Description

The present invention relates to an assembling fence for livestock, a temporary assembly tool for the fence, and an installation method for the fence.

Traditionally, livestock fences have been used on farms to enclose livestock. In addition, livestock fences are used for internal partitions in the ranch. As such a fence for livestock, for example, Patent Document 1 discloses a fence for a ranch. The ranch fence disclosed in Patent Document 1 is used for cattle, and the ranch fence is a plurality of stanchions embedded in the ground around the rangeland at predetermined intervals and a wooden cross rail straddled between the stanchions. And barbed wire. The fence for the ranch has a wooden doorway for people to enter and exit, and a doorway for cattle to enter and exit, and a gate is provided at the wooden doorway and the doorway.

On the other hand, in recent years, the area of the land surrounded by the livestock fence has expanded, and cultivating machines such as tractors have come to enter the land inside the livestock fence. For this reason, wide doorways have come to be seen that allow cultivating machines to pass through. The example shown in FIG. 1 is an example in which the gate G is installed between the columns 3 and 4 provided in the wide doorway 2 provided in the livestock fence 1. In this example, a fence 90 having a rectangular metal frame 91 is attached to the doorway 2.

When the fence 90 provided with the metal frame 91 is used as the gate G, one vertical frame 92L is rotatably attached to a support column 3 provided on one side of the doorway 2 by a mounting member 93 such as a hinge. The other vertical frame 92R is locked by the engaging / disengaging member 94 to the support column 4 provided on the other side of the doorway 2. The fence 90 shown in FIG. 1 has, for example, a width of about 1600 mm and a height of about 980 mm, but there are also fences having a width close to 5000 mm. The fence 90 provided with such a metal frame 91 is used by attaching it to the columns 3 and 4 installed on both sides of the doorway 2, and also by using an attachment member and an engagement / disengagement member to partition the inside of the barn. It may be used without.

Japanese Unexamined Patent Publication No. 61-290175

However, a fence equipped with a metal frame used for a conventional gate is difficult to transport due to the transportation regulations and transportation charges of the transportation company when the width of the doorway is widened and the total length of the fence is increased. There was a problem that it may become.

For example, the maximum size of a package that can be delivered using a public delivery service such as a courier company is often 160 size (the total of the three sides of height and width is 160 cm), which is shown in Fig. 1. A long fence such as the fence 90 shown, which has a total length of 160 cm, did not meet this size regulation and could not be delivered by courier. On the other hand, fences over 160 size may be sent for an additional fee depending on the courier company, and some companies have a maximum size of 200 or 260, and some companies have a maximum size of 450. It can be delivered. However, fences with a size of more than 450 cannot be sent by courier, and the trucks will be chartered independently, which has the problem of extremely high charges.

Further, as shown in FIG. 1, when the conventional fence 90 is used as a gate G provided at the doorway 2 of the livestock fence 1 in the ranch, the rancher may perform various methods according to the size of the doorway 2 provided with the columns 3 and 4. I want a fence of a large size. For this reason, the fence manufacturing company has to prepare a plurality of types of fences, and has a problem that the warehouse fee increases due to the inventory of many types of fences.

Is characterized in that it is engaged and installed so that it can be engaged and disengaged by using an engaging and disengaging member.

A third form of the method for installing a prefabricated livestock fence of the present invention that achieves the above object is a method for installing a prefabricated livestock fence using the above-mentioned prefabricated livestock fence, which is an entrance / exit of a ranch fence. The predetermined number of the second reference fences sandwiched between the two first reference fences is determined according to the length between the first and second columns on both sides, and the two first reference fences and the predetermined number are determined. Correspondence between the first reference fences, the first and second reference fences, or the second reference fences, which are transported to the installation site by public delivery service without being connected to the second reference fence of the number and connected. With the openings of the upper pipe member and the lower pipe member facing each other, insert both sides of the temporary assembly into the facing pipe holes, and place the first end of the pushing member on the outer peripheral surface of the pipe member. By pushing until it reaches, the moving member is moved in the direction away from the fixing member by the separated second ends protruding from the second opening, and the plate-shaped spring is deformed by the moving moving member to make the lock protrusion into the lock hole. By inserting, the pipe members are temporarily connected, and in the temporarily connected state, bolts are inserted into the connecting holes made at the corresponding positions of the vertical plate and the intermediate vertical plate, and they are fastened with nuts to form a livestock assembly type fence. One of the vertical frames of the first reference fence formed and located on both sides is rotatably held by the first strut using a rotation holding member, and the other vertical frame is held by the engaging / disengaging member. It is characterized in that it is installed by engaging with two columns.

The fourth form of the method for installing the assembling fence for livestock of the present invention that achieves the above object is the method for installing the assembling fence for livestock using two sets of the assembling fence for livestock described above, and the fence for ranch. According to the length between the first and second stanchions on both sides of the doorway, the length of each of the two prefabricated livestock fences and the first reference fence on both sides of each prefabricated livestock fence. A predetermined number of second reference fences to be sandwiched between them is determined, and two first reference fences forming each of the two sets of prefabricated livestock fences and a predetermined number of second reference fences are installed without being connected. Open the corresponding upper and lower pipe members between the first reference fences, the first and second reference fences or the second reference fences that are carried and connected to the location by public delivery service. In the state of facing each other, both sides of the temporary assembly are inserted into the facing pipe holes, and the first end of the pushing member is pushed until it reaches the outer peripheral surface of the pipe member, whereby the separation protruding from the second opening. The moving member is moved away from the fixing member by the second end portion, and the plate-shaped spring is deformed by the moving moving member to insert the lock protrusion into the lock hole, whereby the pipe member is temporarily connected and temporarily connected. In this state, insert bolts into the connecting holes made at the corresponding positions of the vertical plate and the intermediate vertical plate, and fasten them with nuts to form two assembling fences for livestock. , The first reference of the one livestock assembly fence The vertical frame of the fence is rotatably held by the first strut using the rotation holding member, and the first reference of the other livestock assembly fence. The vertical frame of the fence is rotatably held by the second support column using a rotation holding member, and the free end of the livestock assembly type fence rotatably held by each of the first and second columns. It is characterized in that the vertical frames of the first reference fence on the side are engaged with each other so as to be disengaged by using an engaging / disengaging member.

In the first to fourth forms of the method for installing the assembly type fence for livestock, the first and second reference fences are transported to the installation location by courier or mail in a non-connected state, and the vertical plates are connected to each other. Before joining the plates to each other or between the vertical plate and the intermediate vertical plate, it is possible to temporarily connect them using a temporary assembly tool and connect them in a temporarily connected state.

According to the assembling fence of the livestock fence of the present invention, the assembling fence is sandwiched between one kind of first reference fence for both sides and the first reference fence, and at least one kind of second is connected. The first reference fence and the second reference fence are transported to the ranch using public delivery services in an unconnected state, and are connected at the ranch to save transportation costs. However, it has the effect of being able to provide a fence that matches the width of the entrance and exit of the ranch at low cost.

Further, according to the temporary assembly tool for the assembly type fence of the livestock fence of the present invention, when the vertical plates are connected to each other, the intermediate vertical plates are connected to each other, or the vertical plates and the intermediate vertical plates are connected by using bolts and nuts, the upper part is used. The pipes and the lower pipes can be easily temporarily connected to each other, and since the connecting holes overlap in this state, the connection can be easily performed.

Further, according to the method of installing the assembly type fence for livestock fences of the present invention, the doorways of various widths provided in the fences installed on the ranch are opened to one side when the width of the doorways is narrow. If the width is wide, installing it in a double-door state has the effect of allowing smooth opening and closing.

The livestock assembly type fence described in this embodiment is mainly used for cattle, but the livestock is not specialized for cattle, and various livestock are also the livestock assembly type of the present invention. It goes without saying that fences can be used. Further, in the following description, as a general rule, the connection between the reference fences is referred to as a connection, and the connection between the vertical plates is referred to as a connection.

FIG. 2A is a front view showing the configuration of another example livestock fence 80, which is longer than the conventional fence 90 shown in FIG. The outer frame 85 of the livestock fence 80 includes vertical pipes 81 and 82, an upper pipe 83, and a lower pipe 84, and a reinforcing member 86 is provided inside the outer frame 85. The total length of this livestock fence 80 is less than 3 m, and it cannot be delivered by courier. Therefore, in the present invention, the conventional livestock fence 80 is divided into three at the position indicated by the line C1-C1 and the position indicated by the line C2-C2 to obtain three small fences F1, F2, and F3. If the width of each of the three small fences F1, F2, and F3 is 90 cm and the height is 90 cm, the width is about 5 cm, so the total length, width, and height is about 185 cm, and up to 200 sizes can be delivered. It will be possible to deliver by courier.

Here, since the small fence F1 having the vertical pipe 81 and the small fence F3 having the vertical pipe 82 have a line-symmetrical shape, the small fence F3 having the vertical pipe 82 is left and right of the small fence F1 having the vertical pipe 81. It turns out that you should reverse. Therefore, in the present invention, when making an equivalent fence 80 for livestock shown in FIG. 2 (a), as shown in FIG. 2 (b), two first reference fences provided with a curved portion 19 are provided. We decided to combine 10 with one second reference fence 20 placed in the middle of the fence.

Then, the two first reference fences 10 and the one second reference fence 20 are sent to the farm by courier, and the two first reference fences 10 and the one second reference fence 20 are delivered to the farm. Arrange as shown in FIG. 2 (b). In this state, if the vertical plate 12 of the first reference fence 10 and the intermediate vertical plate 22 of the second reference fence 20 are connected by the bolt 35 and the nut 36 on the farm, as shown in FIG. 2C, Assembled fence 70 equivalent to the livestock fence 80 shown in FIG. 2A can be made.

As an application example, two first reference fences 10 and two second reference fences 20 are sent to the farm by courier, arranged side by side as shown in FIG. 2 (d), and adjacent vertical plates are attached to bolts 35. When fastened with the nut 36, a prefabricated fence 70L longer than the prefabricated fence 70 shown in FIG. 2C is completed.

The rod 44 is fixed to the insertion hole 41A of the tubular portion 41 of the sleeve 40, and the lengths of the portions of the two rods 44 protruding from the tubular portion 41 are equal. The inner diameter of the engaging / disengaging ring 45 is large, and the rods 44 can be prevented from being separated by inserting the adjacent rods 44.

Here, the first reference fence 10 is of one type (this is referred to as fence A), the second reference fence 20 is of two types (the one having the same width as fence A is fence B, and the width is half that of fence A). The type of the assembled fence that will be completed when the fence C is prepared will be described with reference to FIG. In FIG. 9, the internal structures of the fences A, B, and C are omitted, and only the outer shape is shown. The fence with the left and right sides of the fence A reversed is described as the fence A.

FIG. 9A shows three types of fences A, B, and C. Here, the form of an assembling fence formed by using fences A, B, and C is short in the lateral direction. The explanation will be given in order from. FIG. 9B shows the smallest form of assembling fence that can be formed when three types of fences A, B, and C are prepared, and only two fences A are used. On one side of the fence A , the left and right sides of the fence A are reversed, and the above-mentioned vertical plates are connected to the fence A with bolts and nuts.

The next form is a form in which one second reference fence is sandwiched between two first reference fences, and FIG. 9C is a form in which a fence C is sandwiched between the fence A and the fence A and connected. It is an assembly type fence, and FIG. 9D is an assembly type fence connected by sandwiching a fence B between the fence A and the fence A. The next form is a form in which two second reference fences are sandwiched between two first reference fences, and FIG. 9E shows a fence B and a fence C between the fence A and the fence A. It is an assembly type fence connected by sandwiching one by one, and FIG. 9F is an assembly type fence in which two fences B are sandwiched between fence A and fence A and connected. In this way, if the types and number of the second reference fences 20 sandwiched between the two first reference fences 10 are increased, the length of the prefabricated fence can be increased as shown in FIG. 9 (g). Therefore, the description of the forms after FIG. 9 (g) will be omitted.

Here, the reinforcement of the prefabricated fence will be described. As shown in FIG. 9 (g), if the total length of the prefabricated fence becomes long, bending or deformation may occur at the connecting portion. In such a case, a rod for preventing deformation may be incorporated in the diagonal direction of the assembled fence. An example of incorporating the deformation prevention rod into the assembly type fence will be described with reference to FIG.

As shown in FIG. 10, when the deformation prevention rod 9 is incorporated into the assembly type fence 70, the vertical plate 12 of the first reference fence 10 and the intermediate vertical plate 22 of the second reference fence 20 are replaced with FIG. The wide vertical plates 12A and 22A shown in 3 (a) are used. In this case, the elongated holes 8 provided in the wide vertical plates 12A and 22A are located on the same side of the first and second reference fences 10 and 20. The width of the elongated hole 8 in the lateral direction is formed to be larger than the diameter of the deformation prevention rod 9, and the length of the elongated hole 8 in the longitudinal direction is such that the deformation prevention rod 9 diagonally attaches the prefabricated fence 70. The length is such that it does not interfere with the deformation prevention rod 9 when arranged so as to cross.

In the embodiment shown in FIG. 10, after the assembly type fence 70 is assembled, the deformation prevention rod 9 is inserted into the elongated holes 8 of the wide vertical plates 12A and 22A, and one end of the deformation prevention rod 9 is inserted into the first reference fence 10. Weld to the lower end of the vertical pipe 11 and weld the other end to the curved portion 19 of the first reference fence 10 to fix it. Further, the portion where the deformation prevention rod 9 and the elongated holes 8 of the wide vertical plates 12A and 22A in contact with the deformation prevention rod 9 intersect with the wide deformation prevention rod 9 is also welded and fixed. Further, the intersection of the deformation prevention rod 9 and the reinforcing member 16 intersecting the rod 9 may be welded.

In this way, by arranging the deformation prevention rod 9 diagonally with respect to the assembly type fence 70 and welding after assembling the assembly type fence 70, the deformation of the assembly type fence 70 can be prevented. Instead of the deformation prevention rod 9, a wire or a wire provided with a turnbuckle may be used to apply tension between the curved portion 19 of the prefabricated fence 70 and the diagonal corners. When a wire is used, the wire can be inserted into the elongated hole 8, but a hole for inserting the wire is provided in a portion of the wide vertical plates 12A and 22A where there are no connecting holes 12H and 22H, and the wire is inserted through this hole. You can also do it. Further, the wire is hooked at the lower end of the vertical pipe 11 of the first reference fence 10 at one end and the curved portion 19 of the first reference fence 10 at the other end, and the portion between them is hooked. It can be provided in a reciprocating state while being inserted into a hole for inserting a wire.

11 (a) to 11 (f) show an embodiment in which the deformation prevention rod 9 is obliquely incorporated into the assembly type fence 70 of the embodiment shown in FIGS. 9 (b) to 9 (g). .. The length of the elongated holes 8 provided in the wide vertical plates 12A and 22A in the longitudinal direction is such that the deformation prevention rods 9 are incorporated into the assembly type fence 70 of the embodiment shown in FIGS. 9 (b) to 9 (g), respectively. Even in this case, the length is provided so that the deformation prevention rod 9 can be inserted.

Further, as shown in FIG. 9 (f), when the total length of the assembly type fence 70 is long and the length of the deformation prevention rod 9 is long, the deformation prevention rod 9 is used as shown in FIG. 9 (g). It is possible to reinforce using two. Further, if the deformation prevention rod 9 cannot be delivered to the farm by courier due to its length, it can be lengthened by welding a plurality of deformation prevention rods 9 having a length that can be carried by courier at the farm. The deformation prevention rod 9 to be incorporated into the assembling fence 70 may be reinforced from the side surface by inserting the elongated holes 8 provided in the wide vertical plates 12A and 22A described above, and the number of reinforcing rods 9 may be increased. The length and installation location are not particularly limited.

FIG. 12A facilitates the opening / closing operation of the assembling fence 70 on the engagement / disengagement side with the support 4 of the assembly fence 70 installed between the columns 3 and 4 shown in FIG. 7A. An embodiment in which the caster 50 is attached is shown. The assembling fence 70 is rotatably attached to the support column 3 by a rotation holding member 5, and operates to open and close the doorway 2. However, if the opening / closing operation does not go smoothly, the assembly type fence 70 on the support column 4 side The caster 50 can be attached to the lower end of the vertical pipe 11 of the 70. The casters 50 can smoothly open and close the assembling fence 70 by supporting the load of the assembling fence 70 and traveling on the ground.

FIG. 12B shows an embodiment of the structure of the caster 50 shown in FIG. 12A and the method of attaching the caster 50 to the prefabricated fence 70.

It includes a U-shaped hook 58 and a nut 59. The fork 56 can be turned 360 degrees with respect to the top plate 55.

In the embodiment described with reference to FIG. 6, the width of the second reference fence 20 is fixed, and the width of the prefabricated fence 70 is the second reference fence sandwiched and connected between the two first reference fences 10. It was decided by the number and type of 20. On the other hand, if there is one telescopic fence whose width can be changed in the second reference fence 20 of a plurality of types, the prefabricated fence 70 can correspond to the width of the entrance and exit of the livestock fence of various farms. Can be made to. Here, the structure of the telescopic fence 20C, which is the second reference fence with a changed width, and its usage status will be described with reference to FIGS. 14 and 15.

FIG. 14 shows an embodiment of the structure of the telescopic fence 20C whose width can be changed. In the telescopic fence 20C, the intermediate upper pipe 23 and the intermediate lower pipe 24 of the second reference fence 20S shown in FIG. 6C are divided (divided into two equal parts) at the central portion thereof, and the telescopic mechanism 60 is provided in the divided portion. It is formed by sandwiching it. Then, the width of the telescopic fence 20C is changed from the width of the second reference fence 20S shown in FIG. 6 (c) to the width of the second reference fence 20 shown in FIG. 6 (b) by the telescopic mechanism 60. Enabled to change within the range. The intermediate upper pipe 23 and the intermediate lower pipe 24 of the telescopic fence 20C are hollow pipes having the same dimensions as the upper pipe 13 and the lower pipe 14 of the first reference fence 10.

As shown in FIG. 14A, the telescopic mechanism 60 includes two slide rods 61, a central vertical frame 62, an enlarged fixture 63, and a plurality of stretchable ropes 64. The two slide rods 61 have a thickness that allows them to be slidably fitted into the pipe holes of the intermediate upper pipe 23 and the intermediate lower pipe 24 located on both sides of the expansion / contraction mechanism 60. Then, the central portions of the two slide rods 61 are vertically connected at the upper end portion and the lower end portion of the central vertical frame 62. In this embodiment, the central vertical frame 62 is drawn in a flat plate shape, but the central vertical frame 62 does not have to be in a flat plate shape. The fixture 63 is a screw for fixing the positions of the two slide rods 61 fitted in the pipe holes of the intermediate upper pipe 23 and the intermediate lower pipe 24, and is a through hole provided in the intermediate upper pipe 23 and the intermediate lower pipe 24. It is screwed onto 26 from the direction indicated by arrow A or arrow B.

Further, the elastic rope 64 is provided between both sides of the central vertical frame 62 and the two intermediate vertical plates 22, respectively, and the two slide rods 61 are the pipe holes of the intermediate upper pipe 23 and the intermediate lower pipe 24. When you immerse yourself in 27, its length shrinks. The fixture 63 is screwed into the through hole 26 provided in the intermediate upper pipe 23 and the intermediate lower pipe 24, and the position of the slide rod 61 is fixed by screwing. As the elastic rope 64, an elastic rope, a tow rope, or a tension spring can be used. Further, instead of the stretchable rope 64, a stretchable attachment member such as a turnbuckle may be provided between the ropes to adjust the total length of the rope.

FIG. 14B shows a state in which the second reference fence 20C shown in FIG. 14A is assembled, expanded to the maximum, and fixed by the fixture 63. The width of the telescopic fence 20C at this time is equal to or less than the width of the second reference fence 20 shown in FIG. 6 (b). In this state, both ends of the slide rod 61 are inserted to the depth of more than half the length of the intermediate upper pipe 23 and the intermediate lower pipe 24, and the insertion portion of the slide rod 61 into the intermediate upper pipe 23 and the intermediate lower pipe 24 is inserted. It is designed so that it does not rattle. At this time, the elastic rope 64 can prevent the intermediate vertical plate 22 from being further opened.

FIG. 14C shows a state in which the telescopic fence 20C shown in FIG. 14B is brought closer to the most contracted state and fixed by the fixture 63. When the telescopic fence 20C is in the most contracted state, the width of the telescopic fence 20C becomes close to the width of the second reference fence 20S shown in FIG. 6 (c). As the width of the telescopic fence 20C is reduced in this way, both ends of the slide rod 61 project outward from the ends of the intermediate upper pipe 23 and the intermediate lower pipe 24.

On the other hand, even when the width of the telescopic fence 20C is reduced and both ends of the slide rod 61 project outward from the ends of the intermediate upper pipe 23 and the intermediate lower pipe 24, the telescopic fence 20C is adjacent to the telescopic fence 20C. As shown in 15, the first reference fence 10 or the second reference fence 20. The upper pipe 13 and the lower pipe 14 of the first reference fence 10, the intermediate upper pipe 23 and the intermediate lower pipe 24 of the second reference fence 20 are all hollow pipes having the same dimensions.

That is, the upper pipes 13, 23 and the lower pipes 14, 24 of the adjacent first reference fence 10 or the second reference fence 20 are all hollow pipes having the same dimensions. Therefore, the protruding portion 61E of the slide rod 61 protruding outward from the ends of the intermediate upper pipe 23 and the intermediate lower pipe 24 slides into the pipe holes 27 of the adjacent upper pipes 13 and 23 and the lower pipes 14 and 24. Will be inserted. As a result, the connection between the telescopic fence 20C and the adjacent first reference fence 10 or the second reference fence 20 is strengthened.

The assembled fence according to the present invention has been described above based on the examples, but the assembled fence of the present invention can be installed on a ranch or a farm as described above. First, the installation when one prefabricated fence is used will be described.
(1) First, a combination (number) of the second reference fences sandwiched between the two first reference fences according to the length between the first and second columns on both sides of the entrance and exit of the ranch fence. Or type) is determined. In this case, if the telescopic fence 20C described with reference to FIGS. 14 and 15 is used, the length can be adjusted to the length between the first and second columns.

(2) The first and second fences of the determined combination will be delivered to the installation location by courier or mail without connecting. Since the first and second fences of the present invention are all housed in a size that can be delivered by courier, they can be delivered to the installation location at a low fare.

(3) When the second reference fence is a single number, the vertical plate of the first reference fence facing each other and the intermediate vertical plate of the second reference fence are combined to form an assembly type fence at the installation location. When there are a plurality of second reference fences, the vertical plates of the first reference fence facing each other and the intermediate vertical plates of the second reference fence are joined, and the intermediate vertical frames of the second reference fences facing each other are connected to each other. Join to form a prefabricated fence. It is also possible to make a prefabricated fence by using only two first reference fences.

(4) In the assembled fence assembled in this manner, one vertical pipe of the first reference fence is rotatably held by the first support column using a rotation holding member, and the other vertical pipe is engaged. It can be installed by engaging with the second support column using the detachable member.

Next, the installation when two assembling fences are used will be described, but here, only the parts different from the installation method when one assembling fence is used will be described. In (1), the length of each of the two prefabricated fences and the number of both sides of each prefabricated fence are matched to the length between the first and second columns on both sides of the entrance and exit of the ranch fence. The difference is that the combination (number or type) of the second reference fence sandwiched between the first reference fences is determined. The procedures of (2) and (3) are the same. In (4), the vertical pipe of one of the first reference fences of the two assembly type fences is rotatably held by the first support column by using the rotation holding member, and the other first reference fence is rotatably held. The vertical pipe of the above is rotatably held by the second support column. Then, if the vertical pipes on the free end side of the two assembly type fences rotatably held by the first and second columns are engaged with each other so as to be disengageable by using the engagement / disengagement member, the two assembly types The type fence can be installed between the first strut and the second strut so that the double doors can be opened.

FIG. 16 is a perspective view showing an embodiment of a specific embodiment of the reinforcing member 16 in the first reference fence 10 and the second reference fence 20 shown in FIG. 4A. In this embodiment, in order to clarify the structure of the reinforcing member 16, the vertical plate 12, the outer frame 15, and the intermediate vertical plate 22 are drawn by virtual lines. Further, the illustration of the connecting hole and the bolt and nut for connecting the first reference fence 10 and the second reference fence 20 is also omitted. The vertical reinforcing member 16V attached and reinforced between the upper pipe 13 and the lower pipe 14 of the first reference fence 10 and between the upper pipe 23 and the lower pipe 24 of the second reference fence 20 has a flat plate shape. Further, the horizontal reinforcing member 16H attached and reinforced between the vertical pipe 11 and the vertical plate 12 of the first reference fence 10 and between the two intermediate vertical plates 22 of the second reference fence 20 is a round bar. ..

The wide surface of the vertical reinforcing member 16V is arranged so as to face the vertical plate 12 and the intermediate vertical plate 22. On the other hand, both ends of the vertical reinforcing member 16V are twisted 90 degrees with respect to the wide surface so as to be orthogonal to the wide surface, so that the end surface of the vertical reinforcing member 16V is the upper pipe 13. It is parallel to the longitudinal direction of the lower pipe 14, the intermediate upper pipe 23, and the intermediate lower pipe 24. Therefore, the end face of the vertical reinforcing member 16V on the first reference fence 10 can be welded along the longitudinal direction of the upper pipe 13 and the lower pipe 14, and the end face of the vertical reinforcing member 16V on the second reference fence 20 can be welded. Can be welded along the longitudinal direction of the intermediate upper pipe 13 and the intermediate lower pipe 14.

Further, FIG. 18 (c) is a partially enlarged view of portion C of FIG. 18 (a). When the pipe holes of the upper pipes 13 and 23 and the lower pipes 14 and 24 are closed by both ends of the vertical plate 12', the wide vertical plate 12A', the intermediate vertical plate 22', and the wide intermediate vertical plate 22A', the upper pipe is used. The entire circumferences of 13 and 23 and the lower pipes 14 and 24 are welded to the vertical plate 12', the wide vertical plate 12A', the intermediate vertical plate 22', and the wide intermediate vertical plate 22A'. In this case, as shown in an example of FIG. 18C, since the welded portion S between the intermediate vertical plate 22'and the upper pipe 23 extends over the entire circumference of the upper pipe 23, the welding strength is increased and the first reference fence is used. The strength of the 10 and the second reference fence 20 is increased.

In FIG. 19A, when the first and second reference fences 10 and 20 shown in FIG. 4A are connected, the upper pipe 13 and the upper pipe 23 and the lower pipe 14 and the lower pipe 24 are bolted 35. It is an exploded perspective view which shows the structure which tentatively connects using a temporary assembly tool 70J before connecting with a nut 36. Further, FIG. 19B is a partially enlarged side view showing the structure of an embodiment of the temporary assembly tool 70J shown in FIG. 19A. In the temporary assembly tool 70J, for example, before fastening the first and second reference fences 10 and 20 with the bolt 35 and the nut 36, the upper pipe 13 and the intermediate upper pipe 23 and the lower pipe 14 and the intermediate lower pipe 24 are used. Temporarily connects the connection part of. Here, the structure of an embodiment of the temporary assembly tool 70J will be described with reference to FIGS. 19B and 20, but only when the temporary assembly tool 70J is inserted between the upper pipe 13 and the upper pipe 23. The description will be omitted when the connection portion between the lower pipe 14 and the lower pipe 24 is temporarily connected by the temporary assembly tool 70J.

The temporary assembly tool 70J includes a fixing member 71, moving members 72 provided on both sides of the fixing member 71, and a plate-shaped spring 73 and a moving member 72 to which a plurality (four in this embodiment) are attached to the outer peripheral portion of the fixing member 71. It is configured to include a pushing member 74 to be moved. The fixing member 71 has a columnar shape, and the curved side surface has four groove portions 71M for attaching the central portion 73B of the plate-shaped spring member 73. The width of the groove portion 71M is the same as the width of the plate-shaped spring member 73, and the height from the bottom surface of the side surface of the groove portion 71M is the same as the thickness of the plate-shaped spring member 73. The central portion 73B of the plate-shaped spring member 73 has a screw hole 73H, and the groove portion 71M facing the screw hole 73H also has a screw hole 71H. The plate-shaped spring member 73 is attached to the fixing member 71 by inserting the screw 75 into the screw hole 73H and screwing it into the screw hole 71H.

In addition, in one groove portion 71M of the fixing member 71, a guide hole (bifurcated passage) 71A which is divided into two parts in the middle and smoothly communicates with the opening 71B which opens at the center of both end faces 71F of the fixing member 71 is opened. Has been done. The plate-shaped spring 73 attached to the groove portion 71M provided with the guide hole 71A is provided with a through hole 73A overlapping the guide hole 71A at a position facing the guide hole 71A. Further, both side portions of the central portion 73B of the four plate-shaped springs 73 are inclined portions 73S that are bent and inclined in the axial direction passing through both end surfaces 71F of the fixing member 71.

The inclined portion 73S can be deformed to the outside when pushed from the inside. A lock protrusion 73L is provided on the upper surface near the tip of the inclined portion 73S. The lock protrusion 73L is inserted from the inside into the lock hole 13H provided in the upper pipe 13 (the lock hole provided in the upper pipe 23 is not shown). The moving member 72 has a truncated cone shape, and the inclination of the side surface between the upper base and the lower base is an inclination along the inclination of the inclined portion 73S of the plate-shaped spring 73. The moving member 72 is surrounded by a plate-shaped spring member 73 so as not to come out from both sides of the fixing member 71, and when pushed from the fixing member 71 side, the moving member 72 moves in a direction away from both end surfaces 71F of the fixing member 71. Then, the inclined portion 73S of the plate-shaped spring 73 can be pushed up.

The pushing member 74 has a rod shape, and the cross-sectional shape in the direction perpendicular to the longitudinal direction is provided in the guide hole 73A provided in the central portion 73B of one plate-shaped spring 73 and in the groove 71M of one fixing member 71. It has a shape that allows it to pass through the hole 71A. The pushing member 74 has a slit 74S in the longitudinal direction, and the tip portion of the pushing member 74 can be separated to the left and right by the slit 74S. Further, the push member 74 is made of a material that cannot be deformed in the longitudinal direction but can be deformed and curved in the lateral direction. When the pushing member 74 is inserted into the hole 71A through the through hole 73A from the direction of the tip portion having the slit 74S, the pushing member has the guide hole 71A bifurcated, so that the tip portion side is separated to the left and right.

The pushing member 74 is pushed into the fixing member 71 until the end surface on the tip end side where the slit 74S is located reaches the opening 71B, and in this state, the rear end portion of the pushing member 74 on the opposite side of the opening 71B is a plate-shaped spring 73. It protrudes from the guide hole 73A. This state is shown in FIG. 21A, and the temporary assembly tool 70J is delivered in this state. When the first reference fence 10 and the second reference fence 20 are connected, the temporary assembly tool 70J is inserted into the pipe holes 27 of the upper pipe 13 and the upper pipe 23 so that the pushing member 74 faces upward. Therefore, recesses 13C and 23C for receiving the temporary assembly tool 70J are provided on the upper side of the upper pipe 13 and the end faces of the upper pipe 23.

When the temporary assembly tool 70J is inserted into the pipe holes 27 of the upper pipe 13 and the upper pipe 23, and the rear end side without the slit 74S protrudes from the recesses 13C and 23C in the connecting portion, the upper pipe 13 and the upper pipe 23 are , Not joined by the temporary assembly tool 70J. Therefore, in this state, the end surface of the rear end portion of the pushing member 74 protruding from the connecting portion of the upper pipe 13 and the upper pipe 23 is hit with a hammer 76. Then, the pushing member 74 moves in the guide hole 71A without changing the length in the longitudinal direction, and the tip portion protrudes from the opening 71B to push the moving member 72. As a result, the moving member 72 moves away from the fixing member 71 and pushes up the inclined portion 73S of the plate-shaped spring 73.

When the end portion of the pushing member 74 is continuously hit with the hammer 76, the end portion of the pushing member 74 eventually reaches the outer peripheral surfaces of the upper pipe 13 and the upper pipe 23, and does not move any more. This state is shown in FIG. 21 (b). In this state, the inclined portion 73S approaches the inner surfaces of the upper pipe 13 and the upper pipe 23, and the lock protrusion 73L projecting from the inclined portion 73S is provided in the upper pipe 13 and the lock holes 13H and 23H provided in the upper pipe 23, respectively. Immerse yourself. Since the engagement between the lock protrusion 73L and the lock holes 13H and 23H occurs in all the plate-shaped springs 73, the upper pipe 13 and the upper pipe 23 are locked and connected by the temporary assembly tool 70J.

The length of the pushing member 74 protruding from the temporary assembly tool 70J is the end surface of the tip opposite side of the pushing member 74 when the rear end portion of the pushing member 74 reaches the outer peripheral surfaces of the upper pipes 13 and 23 by the hammer 76. The length of the lock protrusion 73L may be set so as to immerse in the lock holes 13H and 23H, respectively, by the moving member 72 pushed by the moving member 72.

Can be used for connection. That is, when the first reference fence 10 and the second reference fence 20 are to be fastened with the bolt 35 and the nut 36, the connecting hole 12H of the first reference fence 10 and the connecting hole 22H of the second reference fence 20 It is troublesome to align.

In such a case, before fastening the first reference fence 10 and the second reference fence 20 with the bolt 35 and the nut 36, first, the temporary assembly tool 70J is used to connect the upper pipe 13 of the first reference fence 10 and the second reference fence 20. The upper pipe 23 of the reference fence 20 of 2 is temporarily connected by the above-mentioned method. Next, the lower pipe 14 of the first reference fence 10 and the lower pipe 24 of the second reference fence 20 are temporarily connected by the temporary assembly tool 70J by the method described above. Then, since the connecting holes 12H of the vertical plate 12 and the connecting holes 22H of the intermediate vertical plate 22 all overlap, the first reference fence 10 and the second reference fence 20 using the bolts 35 and nuts 36 can be easily fastened. be able to.

Therefore, when the above-mentioned prefabricated fence of the present invention is sent to a ranch or farm for installation, whether one prefabricated fence is assembled and used, or two prefabricated fences are assembled and used as a board, bolts and nuts are used. If the first reference fence 10 and the second reference fence 20 are temporarily connected using the temporary assembly tool 70J before connecting the first reference fence 10 and the second reference fence 20 using the above. , The first reference fence 10 and the second reference fence 20 can be easily fastened using the bolt 35 and the nut 36.

In FIG. 22A, when the first and second reference fences 10 and 20 shown in FIG. 4A are fastened, the upper pipe 13 and the upper pipe 23 and the lower pipe 14 and the lower pipe 24 are bolted 35. It is an exploded perspective view which shows the temporary assembly tool 70K of another Example which temporarily connects before connecting using a nut 36. 22 (b) is a plan view of the metal plate 70L showing a state before drawing the temporary assembly tool 70K of another embodiment shown in FIG. 22 (a), and FIG. 22 (c) is FIG. 22 (c). It is a partially enlarged side view which shows the structure of the temporary assembly tool 70K shown in a). The temporary assembly tool 70K of this other embodiment also has the upper pipe 13, the intermediate upper pipe 23, and the lower pipe 14 before fastening the first and second reference fences 10 and 20 with the bolt 35 and the nut 36. The connecting portion of the intermediate lower pipe 24 is temporarily connected.

Here, the structure of the temporary assembly tool 70K of another embodiment will be described with reference to FIGS. 22 (a) to 22 (e). Again, the temporary assembly tool 70K is between the upper pipe 13 and the upper pipe 23. Only the case of being inserted into the lower pipe j14 will be described, and the case of temporarily connecting the connecting portion of the lower pipe j14 and the lower pipe 24 with the temporary assembly tool 70K will be omitted.

The temporary assembly tool 70K can be formed into the temporary assembly tool 70K having the shape shown in FIG. 22 (c) by drawing one metal plate 70L shown in FIG. 22 (b). The temporary assembly tool 70K of this embodiment includes an upper pipe fixing portion 77, a vertical plate fixing portion 78, and a connecting portion 79. The upper pipe fixing portion 77 has a shape of being attached around the outer peripheral portions of the upper pipes 13 and 23, and the vertical plate fixing portion 78 has a shape of sandwiching the vertical plates 12 and 22 from both sides. Further, the joint portion 79 is provided with a bolt insertion hole 70H, and the bolt 35 is inserted into this hole and fastened with a nut 36.

When the first and second reference fences 10 and 20 are temporarily connected by the temporary assembly tool 70K, the first and second reference fences 10 and 20 are adjacent to each other as shown in FIG. 22 (d). , The opposing vertical plate fixing portions 78 of the temporary assembly tool 70K are separated and opened. In this state, as shown in FIG. 22 (e), the upper pipe fixing portions 77 are put on the upper pipes 13 and 23, and the overlapping end faces of the vertical plates 12 and 22 are sandwiched between the vertical plate fixing portions 78. Then, when the bolt is inserted into the bolt insertion hole 70H and fastened with the nut 36, the state shown in FIG. 22F is obtained. If the lower pipes 14 and 24 are temporarily connected in the same manner, the connecting holes 12H in the vertical plates 12 and 22 will overlap, so the first and second reference fences 10 and 20 are temporarily connected with the temporary assembly tool 70K. , Can be easily and firmly connected using bolts and nuts 36.

FIG. 23A is a front view of the first reference fence 10 and the second reference fence 20 constituting the assembly type fence 70 of another embodiment of the present invention. The difference between the assembled fence 70 of this embodiment and the assembled fence 70 of the above-described embodiment is as follows.
(A) The point where the upper pipe 13 and the lower pipe 14 of the first reference fence 10 are formed in a U shape via two curved portions 19.
(I) The point that the reinforcing member is composed of only the vertical reinforcing member 16T, and (c) near the curved portion 19 on the upper side of the first reference fence 10, the fence is engaged with the support by using a locking tool. This is a point where a ring 17 for stopping is provided.

As shown in FIG. 23 (b), the first reference fence 10 and the second reference fence 20 of this embodiment are fixed by sandwiching the second reference fence 20 between the two first reference fences 10. As a result, the prefabricated fence 70 can be formed. Since only the vertical reinforcing member 16T is used as the reinforcing member in the assembly type fence 70 of this embodiment, even if the cow inserts the forefoot between the reinforcing member 16T and the reinforcing member 16T, the forefoot is caught by the reinforcing member 16T. Absent. Therefore, the fracture of the forefoot of the cow is prevented and it is safe. In this embodiment, the vertical plate 12 is used to connect the upper pipe 13 and the lower pipe 14 of the first reference fence 10, and to connect the intermediate upper pipe 13 and the intermediate lower pipe 14 of the second reference fence 20. Although the intermediate vertical plate 22 is used, the wide vertical plate 12A, the vertical plate 12'or the wide vertical plate 12A'is used instead of the vertical plate 12, and the wide vertical plate 22A, the vertical plate 22'or is used instead of the intermediate vertical plate 22. A wide vertical plate 22A'may be used.

Further, as shown in FIG. 23 (c), the first reference fence 10 and the second reference fence 20 of the present embodiment have a second reference fence 20 after being connected to the first reference fence 10. By connecting the reference fence 10 of 1 upside down to the second reference fence 20, the ring 17 can be positioned on the diagonal line of the prefabricated fence 70. As a result, the assembly-type fence 70 of the present embodiment can be attached with the deformation prevention rod 9 by using the ring 17 on the diagonal line, and the deformation of the assembly-type fence 70 can be prevented. When a wire is used instead of the deformation prevention rod 9 to prevent the assembly type fence 70 from being deformed, both ends of the wire are hooked on the ring 17 to fix the wire, and the wire intersects the vertical reinforcing member 16T. The portion may be attached by crossing the wire with respect to the vertical reinforcing member 16T in a zigzag manner.

Generally, in Japan, the distance between structures is set in multiples of 90 cm. For example, the distance between columns in a ranch is often determined by the distance between the centers of the columns, and the width of the first and second reference fences is set. If both are set to 90 cm, the prefabricated fence may not fit between the columns. Therefore, it is possible to make the width of the first reference fence, which is arranged only at both ends of the assembled fence, shorter than 90 cm. Specifically, an embodiment in which the width of the first reference fence is 78 cm and the width of the second reference fence is 90 cm is possible.

When the width of the first reference fence is 78 cm and the width of the second reference fence is 90 cm, the distance between the support column for attaching the rotation holding member for rotating and holding the assembled fence and the first reference fence needs to be 8 cm. The distance between the support column to which the engagement / disengagement member is attached and the first reference fence is 16 cm. If the distance between the support and the first reference fence is 16 cm, the engagement / disengagement member for engaging and disengaging the assembled fence with the support can be attached between the support and the first reference fence with a margin.

In FIG. 24, the width of the first reference fence A is 90 cm, and the widths of the two types of second reference fences B and C are 65 cm and 90 cm, respectively. It is explanatory drawing of another embodiment of the combination of the 1st and 2nd reference fences which can be realized. Here, the distance between the columns will be described using the "between" (about 1800 mm) of the shakkanho method. The distance between the columns is generally indicated by the distance between the centers of the columns. Further, the fence is attached to the support column by using a hinge which is a rotation holding member, and the distance between the vertical pipe and the support column in this case is required to be 80 mm.

The leftmost column in the table shown at the top of FIG. 24 shows the distance between the columns in "between", from 1 to 3 and a half. The fourth column from the left in this table shows the distance between the columns minus the hinge width and the column width of 100 mm. Since the distance between struts is the distance between the centers of the struts, the actual distance between struts is the distance between struts minus half the width of the struts on both sides, which is the distance between struts minus the width of the struts. Equal to the distance. Therefore, the distance in the fourth row from the left in this table is the width of the assembly fence that can be attached between the columns and the distance from the vertical pipe on the opposite side of the hinge of the assembly fence to the column (the engagement / disengagement member is attached). It is the total of the space to be used, which is called the clearance here). Generally, a clearance of 30 to 100 mm is required.

The third column from the right side of this table is the optimum width of the prefabricated fence when the width of the first reference fence is 90 cm and the width of the two types of second reference fences is 65 cm and 90 cm. The combinations of are listed in the rightmost column. In this embodiment, the clearances are all 70 mm when the distance between the fences is 1 to 3, which is most suitable for attaching the engagement / disengagement member, and the widths of the first and second reference fences in this embodiment. It can be said that the setting of is one of the ideal settings when the distance between the columns is up to 3.
