JP-A-08-13963

By the way, in the gatepost of Patent Document 1, the outer shell portion is formed by joining the front plate portion and the rear plate portion made of synthetic resin. , misalignment, separation, etc. may occur. In short, since this type of gatepost is installed outdoors, it is impossible to eliminate or drastically reduce the number of partition walls in order to maintain and stabilize durability and strength. Since the gatepost of Patent Document 1 has an internal structure essentially including a partition wall, it can be said that the degree of freedom in designing the internal space is extremely low. In addition, the gatepost of Patent Document 1 cannot be said to have taken into account the durability and strength when a home delivery box or the like is attached.

The present invention has been proposed in consideration of such circumstances, and its object is to provide a gatepost, a gatepost installation structure, and a gatepost installation method that are excellent in durability, strength, and flexibility in designing the interior space. It is in.

In order to achieve the above object, the gatepost of the present invention is a gatepost having a hollow outer shell portion that opens downward, the outer shell portion being made of metal and comprising a front plate portion and a rear plate portion. and a plurality of metal rods are welded to a lower portion within the outer shell portion to connect the front plate portion and the rear plate portion.

In the gatepost installation structure of the present invention, in a state in which a reinforcing bar is inserted through the insertion hole so as to penetrate the gatepost in the front-rear direction, the inner and outer portions of the lower portion of the gatepost including the reinforcing bar and the insertion hole are cement-based underground. It is characterized by being fixed and embedded with a material.

The gatepost installation method of the present invention includes inserting a reinforcing bar into the insertion hole so as to penetrate the gatepost in the front-rear direction, disposing the inner and outer portions of the lower part of the gatepost including the reinforcing bar and the insertion hole in the gatepost construction hole, and It is characterized by pouring a cement-based material into the gatepost construction hole.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings.
First, the basic configuration of the gateposts 10 and 10A will be described with reference to FIGS. 1 to 4 and 9 to 10. FIG.
The main gateposts 10, 10A have a hollow outer shell 20 that opens downward. The shell portion 20 is made of metal and includes a front plate portion 21 and a rear plate portion 22 . A plurality of metal bars 16 that connect the front plate portion 21 and the rear plate portion 22 are welded to the lower portion inside the outer shell portion 20 . Below, the direction in which the front plate portion 21 and the rear plate portion 22 of the gateposts 10 and 10A are arranged is defined as the front-rear (depth, projection) direction.
The gateposts 10 and 10A may be used with a gate attached, or may be erected without a gate attached. Moreover, the gateposts 10 and 10A may be connected to the outer wall, or may be erected independently.

Next, the detailed configuration, installation structure, and installation method of the gatepost 10 according to one embodiment will be described with reference to FIGS. 1 to 7. FIG. As shown in FIGS. 2 and 3, etc., the main gatepost 10 has a striped pattern on its surface, but the striped pattern is omitted from the perspective view of FIG.

As shown in FIG. 1, the outer shell part 20 of the gatepost 10 has a thin rectangular parallelepiped shape like a slate, and has a front part 11, a back part 12, a top part 13 and two side parts 14. As shown in FIG. The bottom part is open. In order to create a monument-like design on the outer surface of the gatepost 10, for example, a striped pattern is formed by continuous elongated protrusions of about 30 to 50 mm in length and 2 to 5 mm in width. As the metal plate, it is preferable to use a rolled checkered plate material (checkered steel plate (checker plate)), or an aluminum checkered plate may be used. It should be noted that other patterns may be used in place of such patterns, and metal plates such as steel plates and aluminum plates without surface patterns may be used. Further, the outer surface of the gatepost 10 may be made glossy by painting, or may be finished to have a matte texture. The height dimension of the gatepost 10 is approximately 1750 mm, the width dimension is approximately 800 mm, and the depth dimension is approximately 150 mm. The gatepost 10 of the present embodiment is thus a wall-shaped gatepost with a small dimension (depth) in the front-rear (prospect) direction.

The gatepost 10 according to this embodiment is installed so that the front part 11 faces the same direction as the front of the building, and is installed, for example, on the front side of the building of a detached house so as to face a road or the like. The outer shell portion 20 has two working plate bodies 30 , one working plate body 30 forming the front plate portion 21 and the other working plate body 30 forming the rear plate portion 22 . The processing plate 30 includes a square flat plate portion 31 and three side wall plate portions 32 connected to three sides of the square flat plate portion 31 (see FIGS. 1 to 4).
The outer shell portion 20 is formed by welding based on a plurality of processed plate bodies 30 formed by processing a flat metal plate. Work plates 30 are formed by joining them together so that a seam 18 runs in the direction.

The rectangular flat plate portion 31 of the processed plate body 30 of the front plate portion 21 includes a mailbox opening 24a, a home delivery box opening 25, an interphone mounting hole 26, and a reinforcing bar 45 (see FIG. 5B) for installing and fixing the gatepost 10. ) are opened. The rectangular flat plate portion 31 of the processed plate body 30 of the rear plate portion 22 is provided with a mailbox mounting opening 24b, a home delivery box opening 25, and two insertion holes 23 through which reinforcing bars 45 for installing and fixing the gatepost 10 are inserted. there is Further, the back plate portion 22 may be provided with a support base 35 for supporting the home delivery box 53 (see FIG. 6) (see the two-dot chain line in FIG. 2B). A nameplate 27 is attached to the upper portion of the mailbox opening 24a (see FIG. 6).

The processed plate body 30 is formed by processing a checkered steel plate having a shape as shown in the developed view of FIG. 4(b). The thickness of the checkered steel plate is about 1.5 mm to 5 mm. If the thickness of the checkered steel plate exceeds 5 mm, the weight of the gate post 10 becomes large and it becomes difficult to handle. Also, if the thickness of the checkered steel plate is 1.4 mm or less, it will be too thin and the strength of the gatepost will be questionable. After processing the delivery box opening 25, the insertion hole 23, etc. in the rectangular flat plate portion 31, the three side wall plate portions 32 are bent and the side wall plate portions 32 are welded to each other to form a processed plate having side walls on three sides. A body 30 (front plate portion 21, rear plate portion 22) is formed.

The two processed plate bodies 30 are connected to each other by welding so that the end faces of the side wall plate portions 32 are butted against each other, and are welded to each other via three bars 16 in the lower part of the internal space 17. The processing plate bodies 30 are connected to each other. A top surface portion 13 and two side surface portions 14 of the gatepost 10 are formed by connecting the side wall plate portions 32 to each other. Although it is desirable that the three bars 16 are arranged substantially parallel to the top surface 13 as in this example, they may be arranged at different height positions.

The gatepost 10 having the above structure can be easily formed from a metal plate as described above, and can be finished strongly. As will be described later, the bottom surface of the gatepost 10 is open so that the cement-based material enters the internal space 17 when the gatepost 10 is installed. Therefore, there is a risk that the strength of the lower part or the whole will be reduced if the top surface 13 alone does not generally have a bottom plate, but the main gate post 10 is made up of a plurality of metal bars 16, the front plate 21 and the rear plate. Since the parts 22 are connected, they can serve as a substitute for the bottom part, and are reinforced by these parts, thereby suppressing the occurrence of obstacles due to aging such as deformation, warping, deviation, and separation of the outer shell part 20 .

In addition, since the outer shell 20 is made of metal and the reinforcing bar 16 is provided in the lower part, there is no need to provide a reinforcing structure in the central part of the internal space 17. 17 can be designed freely, and the internal space 17 can be used freely. For example, a delivery box 53 larger than that shown in the figure may be provided, or the delivery box 53 may be provided at a different position. Further, for example, if an opening is formed in the rectangular flat plate portion 31 and an openable and closable door is provided therein, the internal space 17 can be used as a storage space.

In addition, since the striped pattern appears on the surface of the outer shell part 20, the gatepost 10 can be stylish and aesthetically pleasing while having a simple structure. In addition, although a welded seam 18 appears on the top surface portion 13 and the side surface portion 14, if a regular striped pattern is continued without deviation between the two processed plates 30 as shown in the example, it will be aesthetically pleasing from any angle. The gatepost 10 can be excellent in

Furthermore, since the two processed plates 30 are welded at the flat top surface portion 13 and the side surface portion 14, the welding work is easy, and the gatepost 10 can be manufactured efficiently without making a mistake in the vertical direction. . In addition, since the working plates 30, 30 having substantially the same shape are used, it is easy to manage the inventory of members.

Next, the installation method and installation structure of the gatepost 10 will be described with reference to FIGS. 5 to 7. FIG. The gatepost 10 is installed with its lower portion buried in the ground. The part to be embedded is at least about 20 to 30 cm from the lower end including the insertion hole 23 .
The installation method is as follows.

(1) First, an H-shaped gatepost construction hole 40 as shown in FIG. 5(a) is provided at the installation location of the gatepost 10 (see FIG. 5(a)). The gatepost construction hole 40 has a central groove 42 and two vertical grooves 41 . The central groove 42 is a groove in which the central portion of the gate post 10 excluding both ends in the width direction is arranged. The two longitudinal grooves 41 are grooves in which both ends including the insertion hole 23 of the gate post 10 are arranged. A section indicated by 43 in FIG.

(2) Before and after the work of forming the gatepost construction hole 40 in (1), the reinforcing bars 45 are inserted in the longitudinal direction through the two insertion holes 23 of the outer shell portion 20 of the gatepost 10 . In order to enhance the anchoring effect of the cement-based material and prevent misalignment during the fixing work of the gatepost 10 described later or after the cement-based material hardens, the outer side of the insertion hole 23 is placed as shown in FIG. 5(b). It is desirable to form a curved portion in a portion of the reinforcing bar 45 .
A wire cord (not shown) of the intercom 51 is covered with a protective tube (not shown), and the wire cord is pulled out from the opening at the lower end of the gatepost 10 .

(3) Next, a cement-based material for temporarily placing the gatepost 10 is applied to the gatepost construction hole 40 at a portion near the lower part of the gatepost 10, including both longitudinal grooves 41 and the central groove 42 (Fig. 5(a) ( Pour into the cross-hatched portion in b)). In this case, it is desirable to pour the cement-based material to such a height that the insertion hole 23 is filled when the gatepost 10 is temporarily placed, but the insertion hole 23 may be hidden during the main injection of the cement-based material. .
Examples of cementitious materials include cement, mortar, and concrete. Concrete is preferably used to provide a strong installation structure.

(4) Then, the gatepost 10 is temporarily placed in the central groove 42 so that both ends (the insertion hole 23 and the reinforcing bars 45) in the width direction of the gatepost 10 are arranged in the vertical grooves 41 of the gatepost construction hole 40 (FIG. 5). (a)). Temporary placement should be done so that the insertion hole 23 in the lower part of the gatepost 10 is filled with the cement-based material and the gatepost 10 is in a horizontal state. By temporarily placing in this way, the reinforcing bars 45 and the insertion holes 23 are mostly buried in the cement-based material.
In addition, the temporary placement causes the cement-based material to enter the lower space inside the outer shell portion 20 . A larger through-hole 23 may be provided so that the cement-based material enters the internal space 17 through the through-hole 23 .
Also, the wire cord should be taken out so that it can be wired to the power supply.

(5) With the gatepost 10 temporarily placed, further cement-based material is poured into the gatepost construction hole 40 to such an extent that the reinforcing bars 45 and the insertion holes 23 are not exposed. In the example shown. The cement-based material is injected so that the bar 16 is also buried. After that, the cementitious material is cured (see FIG. 5(b)).
The cementitious material is poured into the vertical groove 41 in this way, and is also poured into the central groove 42 so as to fill the gap between the central groove 42 and the gate post 10 . Note that the cement-based material may be poured into the internal space 17 from the delivery box opening 25 . Note that the bar 16 may also be embedded in the cement-based material.
By hardening the cement-based material in this way, a strong reinforced concrete/cement-based gatepost installation structure is formed.

(6) With the gatepost 10 installed, the surface of the gatepost construction hole 40 is covered with soil or gravel so that the cement-based material and the surplus soil portion 43 are not exposed.

To summarize the above gatepost installation method, the reinforcing bar 45 is inserted into the insertion hole 23 so as to penetrate the gatepost 10 in the front-rear direction, and the lower inner and outer portions of the gatepost 10 including the reinforcing bar 45 and the insertion hole 23 are inserted into the gatepost construction hole 40. In this state, the inner and outer parts of the lower part are fixed with a cement-based material. The installation structure of the gatepost 10 installed in this manner is such that the lower inner and outer parts of the gatepost 10 including the reinforcing bars 45 and the insertion holes 23 are inserted into the insertion holes 23 so as to penetrate the gatepost 10 in the front-rear direction. is assumed to be fixed in the ground with cement-based material and buried.
According to the gatepost installation method described above, since the gatepost 10 has an opening facing downward, the inner and outer parts of the lower part of the gatepost 10 are hardened with a cement-based material so as to communicate with each other, realizing a strong installation structure. be done.

FIG. 6 is a front view showing an installation state in which the lower part of the gatepost 10 is buried in the ground. FIG. 7 is a side view of the same. An intercom 51 , a mailbox 52 and a delivery box 53 are attached to the gatepost 10 , and rear parts of the mailbox 52 and the delivery box 53 protrude rearward from the back side of the outer shell part 20 . A cover for a mailbox 52 is attached to the front of the gatepost 10 (see FIG. 6). Also, the delivery box 53 is supported by the support base 35 (see FIG. 7).

8A and 8B are diagrams showing a modification in which the delivery box 53 is not attached to the gatepost 10, where (a) is a front view of the gatepost, (b) is a side view of the same, and (c) is a plan view of the same. . Although illustration of the bottom view is omitted, it is the same as the bottom view of FIG. , a plurality of metal bars 16 connecting the front plate portion 21 and the rear plate portion 22 are welded. The example shown in FIG. 8 is different from the above example in that the home delivery box 53 is not added, so the opening 25 for the home delivery box is not formed in the rectangular flat plate portion 31 of the processed plate body 30 of the front plate portion 21 . Different but otherwise similar. In FIG. 8, the nameplate 27, the mailbox 52, and the intercom 51 are indicated by dotted lines because they are not limited to the illustration.

Also in the gatepost 10 in the modified example of FIG. Well, the durability, the strength, and the degree of freedom in designing the internal space 17 are excellent, and the internal space 17 can be used freely. In addition, since a striped pattern appears on the surface of the outer shell part 20 and no delivery box is added, the gatepost 10 can be stylish and aesthetically pleasing while having a simpler structure. In addition, although a welded seam 18 appears on the top surface portion 13 and the side surface portion 14, if a regular striped pattern is continued without deviation between the two processed plates 30 as shown in the example, it will be aesthetically pleasing from any angle. It is the same as the above example that the gatepost 10 can be excellent in

Next, a gatepost 10A according to another embodiment will be described with reference to FIGS. 9 and 10. FIG. A striped plate material may also be used as the outer shell 20 of the main gatepost 10A.
