Description

  The present invention relates to a joint for a sheet stopper in a greenhouse, and more particularly to a joint suitable for fixing or reinforcing a sheet stopper to a channel material constituting a purlin or a rafter.

  A greenhouse, a greenhouse that grows and cultivates plants, has a sheet stopper fixed to a channel material consisting of a main house or rafters, and a transparent hard or soft sheet fixed to the sheet stopper to secure the roof, sides, and wife. The sheet is spread on the surface. As such a sheet stopper, for example, one having a structure disclosed in Patent Document 1 has been developed.

  As shown in the reference front view showing the state of use, the seat stopper has a drum-shaped main body, a pair of legs provided on both sides of the main body, and a pair of flanges provided horizontally at the lower ends of the legs. Each of the hooks is fixed to the channel material with screws, and a transparent hard sheet is held on the main body via other screws and caps.

  However, the sheet stopper shown in the above-mentioned Patent Document 1 is not necessarily functionally defective. However, since the collar portion is only fixed with a screw on the channel material, the screw and the screwed portion of the screw are not provided. If it rusts or loosens due to aging, the holding force on the sheet stopper will be weak, especially if strong wind acts on the sheet, or if the channel material vibrates due to an earthquake or strong wind, the screw will loosen, and the sheet stopper will be against the channel material. May loosen, come off, and the spread sheet may be distorted or damaged.

  For this reason, as shown in Patent Document 2, Patent Document 3, and Patent Document 4, a joint that can be reinforced so that the sheet stopper does not loosen or come off from the channel material even if the screw loosens and the holding force weakens. Has been developed.

  These joints are provided with a support piece, an opening formed at the upper end of the support piece, and a pair of hooks provided on both sides of the upper end of the opening. The tool is inserted, and then the sheet stopper is held by the hook while the support piece is fixed to the channel member via a screw or a wedge.

  However, since the pair of hooks of these joints are respectively in contact with the hook provided on the lower end side of the main body of the seat stopper and the inclined surface of the main body at a position higher than the hook, the height positions of the hooks are different.

  For this reason, when these joints are used for fixing or reinforcing a sheet stopper provided with a pair of horizontal hooks on both sides of the lower end of the main body as shown in the above-mentioned Patent Document 1, one of the hooks on one high position is set on one hook. As a result, the joint rattles, and as a result, not only the sheet stopper can be fixed but also cannot be reinforced.

  On the other hand, as shown in Patent Document 5, there is also a joint including a support piece, an opening formed at the upper end of the support piece, and a pair of horizontal hooks facing each other at the same height level on both sides of the upper end of the opening. Has been developed.

  This joint is used for fixing a sheet stopper composed of a dovetail frame with dovetail-shaped side walls, but a pair of hooks face the same horizontal level and have the same height. Since these hooks can be brought into contact with the upper surfaces of the hooks on both sides of the sheet stopper shown in Patent Document 1, it can be used not only for fixing the sheet stopper but also for reinforcement.

Design Registration No. 1575859 (see reference front view showing usage) Japanese Patent No. 4255122 (see FIG. 6, paragraphs 0004 to 0013 and FIG. 3) JP 2014-198986 A (see paragraphs 0010 to 0014, FIG. 5) JP 2017-85939 A (see paragraphs 0003 to 0011, FIG. 5 and FIG. 6) Design Registration No. 1507240 (see reference perspective view)

  However, the joint shown in Patent Document 5 is formed into a U-shape when the opening below the hook is viewed from the front, and the width between both side surfaces of the opening is larger than the width of the sheet stopper, Similarly, it is normal for the depth of the lower part to be longer than the height of the sheet stopper, so when inserting the sheet stopper into the opening, in other words, the opening at the bottom of the fixed sheet stopper. While the joint can be easily fitted with the joint inclined, there are the following problems.

  First, when the sheet stopper is inserted into the opening, there is a gap between the side of the sheet stopper and the inner periphery of the opening, and the joint moves left and right or diagonally in this gap, causing backlash. The manual operation that tries to level the joint is troublesome.

  Secondly, if there is a gap as described above between the side of the sheet stopper and the side surface of the opening, even when the sheet stopper is fixed to the channel material by the joint, the joint will have an external force corresponding to the gap. May move left and right, and as a result, the mounting position of the sheet stopper with respect to the channel material may change, and the spread sheet may be distorted or broken.

  Accordingly, an object of the present invention is to allow a sheet stopper having a pair of horizontal ridges to be accurately and smoothly inserted into the opening from an oblique direction, and after the insertion, a gap is generated between the ridge and the side surface of the opening. It is an object of the present invention to provide a joint that can guide the heel to the base end position of the hook without causing it to be aligned easily and accurately with respect to the sheet stopper and can prevent play.

  In order to achieve the above object, the means of the present invention comprises a support piece, an opening formed at the upper end of the support piece, and a pair of hooks provided horizontally on opposite sides of the upper end of the opening. A joint for coupling a sheet stopper provided with a pair of left and right flange-shaped ridges inserted into the opening portion while crossing a channel material constituting a purlin or a rafter into the channel material; The dimension between the ends is formed to a length that is the same as the width dimension between the ends of the pair of scissors, and the lower end of the opening is formed from the lower base end of the hook on one or both sides of the opening. It is characterized in that a guide surface for heel guidance that is continuous with the corner portion is formed.

According to the invention of each claim, the following effects can be achieved.
A) Since a guide surface for guiding the heel from the lower base end portion of the hook to the lower end corner of the opening is formed on one or both side surfaces of the opening, the heel of the sheet stopper is formed along the guide surface. Can be inserted accurately and smoothly up to the lower end corner of the opening. In other words, the joint can be fitted to the seat stopper while the heel is brought into contact with the guide surface and inclined.
B) Furthermore, after fitting the sheet stopper in the opening, the joint is leveled manually, and then the joint is pushed down manually or via a wedge, the joint support piece is lowered along the guide surface, in other words, The hook of the sheet stopper rises along the guide surface, and finally, the outer base end of the hook hits the lower base end portion of the hook and can be fitted.

  In this state, there is no gap between the side surface of the heel and the inner side surface of the opening, and the joint itself can be prevented from moving laterally, and the joint is positioned at an appropriate position, for example, at the lower center of the seat stopper. it can.

  C) In particular, since the dimension between the lower base ends of each hook is formed to be the same length as the width dimension between the pair of hooks in the sheet stopper, the upper surface of the pair of hooks contacts the lower surface of each hook. When held in contact, there are no gaps on either side of each heel, the joint is restricted from moving laterally, and these members do not move left or right even if an external force is applied to the seat stopper or joint. No looseness is generated, and therefore the joint is not loosened and the sheet stopper can be stably and firmly held.

  As a result, it is possible to prevent the sheet held by the sheet stopper from being distorted or broken.

  Below, the joint which concerns on one embodiment of this invention is demonstrated based on FIGS. In this case, the joint shown in FIGS. 1 to 8 and its use state relate to an embodiment that can be used for reinforcing and fixing the sheet stopper.

  The joint shown in FIGS. 9 to 13 relates to another embodiment used for reinforcing the sheet stopper.

  The joint shown in FIGS. 14 to 15 relates to another embodiment used for reinforcing the sheet stopper.

  The joint shown in FIGS. 16 to 21 and the use state thereof relate to another embodiment used for fixing the sheet stopper.

  A common basic configuration of the joint according to each of the above embodiments includes a support piece 1, an opening 2 formed at the upper end of the support piece 1, and a pair of horizontally provided opposite to both sides of the upper end of the opening 2. The channel member 9 includes a sheet stopper 8 including a pair of left and right flange-shaped rods 7 and 7 inserted into the opening 2 while crossing the channel member 9 constituting the purlin or rafter. A joint to be coupled, wherein the dimension C between the lower base ends 5C, 5C of the hooks 3A, 3B is the same length as the width dimension L in the short direction of the sheet stopper 8, and is further open 2 on one side or both side surfaces of the hook 3A, the guide surface 4 for guiding a ridge that continues from the lower base end portion 5C of the hook 3A to the lower end corner portion 5A of the opening portion 2 is formed.

  Each embodiment will be described in detail below. A joint P1 shown in FIGS. 1 to 5 is a joint according to an embodiment of the present invention, which can be selectively used for both reinforcing and fixing the sheet stopper 8.

  In this case, the reinforcement means that the sheet stopper 8 is fixed in advance to the channel member 9 made of a C-shaped channel constituting the purlin or the rafter via the screw V, and the rigid transparent sheet S is formed via the sheet stopper 8. Newly when the holding force of the screw V decreases due to rusting or loosening due to aging of the screw V or the screwed portion of the screw V in the state where it is stretched on the roof surface, side surface or wife surface of the greenhouse. The joint P1 is assembled and held on the channel material 9 to supplement the holding force of the screw V.

  On the other hand, the fixing means that the sheet stopper 8 arranged in the direction in which the joint P1 crosses the channel material 9 is attached to the channel material 9 from the beginning. 8 is held.

  In this case, when the joint P1 is used for reinforcement, the wedge K is inserted into the wedge insertion guide holes 1C and 1C provided at the lower end as shown in FIGS.

  On the other hand, when the joint P1 is used for fixing, as shown in FIGS. 6 to 8, the wedge K is inserted into the other wedge insertion guide groove 1D on the opening 2 side.

  As described above, the joint P1 includes the support piece 1, the opening 2 formed at the upper end of the support piece 1, and a pair of hooks 3A and 3B provided horizontally on opposite sides of the upper end of the opening 2. And a sheet stopper 8 having a pair of left and right flange-like ridges 7 inserted while being crossed with a channel material 9 constituting a purlin or a rafter in the opening 2 is coupled to the channel material 9. .

  In the joint P1, as described above, the dimension C between the lower base ends 5C and 5C of the hooks 3A and 3B is the same as the width dimension L (see FIG. 3) between the pair of flanges 7 and 7. Molded to length.

  Further, a guide surface 4 for scissors guidance is formed on one side surface of the opening 2 from the lower base end 5C on the right side to the lower right corner 5A on the right side of the opening 2.

  The illustrated guide surface 4 is composed of a downwardly inclined surface formed from the lower base end portion 5C of the right hook 3B toward the right lower end corner portion 5A. It may be configured by a vertical surface that extends from the upper end of the inclined surface to the lower base end portion 5C of the hook 3B. In short, the hook 7 of the sheet stopper 8 is smoothly inserted into the opening 2 while being inclined, and after the insertion Other shapes may be used as long as the end of the flange 7 can be guided from the lower end corner 5A to the lower base end 5C of the hook 3B.

  In the opening 2, the dimension A between the inner ends of the pair of hooks 3 </ b> A, 3 </ b> B is shorter than the dimension L between the outer ends of the side hooks 7, 7 in the sheet stopper 8. The dimension B between the upper end of the tip of the left hook 3A and the right lower corner 5A is the same as or preferably longer than the dimension L between the outer ends of the flanges 7 and 7. Yes.

  The support piece 1 in the joint P1 is composed of a pair of opposed plate pieces 1A connected by a horizontal bottom plate 1B, and a pair of wedge insertion guide holes 1C, 1C opposed to each other at the lower end of each plate piece 1A are formed. A guide groove 1D for inserting a wedge is formed at the bottom of the opening 2 formed at the upper end of each plate piece 1A. A notch 1G is formed on the lower side surface of each plate piece 1A.

  Also, a screw insertion hole 1F is formed in the bottom plate 1B, and the joint P1 can be fixed to the channel member 9 with a screw inserted into the hole 1F. However, it can be used without the screw insertion hole 1F.

  3 to 5 show a state in which the sheet stopper 8 is reinforced and held by the channel member 9 made of a C-type channel using the joint P1. As shown in FIG. 3, this reinforcing state is based on the premise that the sheet stopper 8 is fixed to the channel member 9 in advance via screws V, and the sheet S is also fixed to the sheet stopper 8 and stretched. While maintaining this state, the joint P1 is inserted into the channel member 9 and the sheet stopper 8 from the lower side of the sheet S.

  The sheet stopper 8 is a long drum-like main body 15, a pair of leg portions 16, 16 provided on both sides of the main body portion 15, and the leg portions 16, 16, as shown in Patent Document 1. And a pair of flange-like ridges 7, 7 provided horizontally at the lower end.

  The sheet stopper 8 is arranged so as to intersect the channel material 9, and the flange 7 is fixed to the channel material 9 via a screw V.

  Further, for example, a transparent hard sheet S is sandwiched between the main body 15 and the cap 17 fitted on the main body 15, and the sheet S is spread on the roof surface or the like.

  In the above state, the sheet stopper 8 is fixed to the channel material 9 via the screw V in advance, but when it is visually confirmed that the holding force of the screw V is reduced, the sheet stopper 8 is held by the joint P1. To reinforce.

  In this case, in the state where the sheet stopper 8 is held by the channel member 9 with the screw V, the joint P1 is manually moved from the inside of the greenhouse of the greenhouse to the lower side of the channel member 9. Insert while tilting.

  At this time, since the notch 1G is formed on the lower side surface of the plate piece 1A, it is prevented from interfering with the channel material 9 at the initial stage of rotation of the plate piece 1A.

  Next, while further tilting the joint P1, the flanges 7 and 7 of the sheet stopper 8 are inserted to the position of the lower end corner 5A of the opening 2, and the lower wedge is returned with the joint P1 returned to a horizontal posture. A wedge K is driven into the insertion guide holes 1C and 1C in a direction crossing the channel material 9.

  As a result, the tightening force of the wedge K acts on the sheet stopper 8 and the joint P1, and since the sheet stopper 8 is fixed by the screw V and does not move, the entire joint P1 is pushed downward, and the upper surface of the channel member 9 is Both ends 7 and 7 of the sheet stopper 8 are firmly sandwiched between the lower surfaces of the hooks 3A and 3B, and the tightening force by the joint P1 is added in addition to the retaining force of the screw V to compensate for the lowered retaining force of the screw V. The sheet stopper 8 is prevented from loosening and dropping off.

  In the above procedure, it should be noted that when the opening 2 is fitted on the outer periphery of the flange 7 while the joint P1 is inclined, in other words, the flange 7 of the sheet stopper 8 is inserted into the opening 2 while being inclined. 3, the outer periphery of the right collar 7 is smoothly guided while being guided to the lower end corner 5A of the opening 2 along the guide surface 4, and as a result, the inclined posture when the joint P1 is inserted is constant and manually The insertion operation of the joint P1 becomes easy, and it is not necessary to adjust the posture every time.

  Next, when the flange 7 reaches the lower end corner 5A, the joint P1 is manually leveled, and when the wedge K is driven into the wedge insertion guide hole 1C in this state, the entire joint P1 is lowered.

  At this time, since the guide surface 4 is in contact with the outer periphery of the right flange 7, the joint P1 descends in a horizontal posture while being guided by the guide surface 4, and finally the end portions of the pair of flanges 7 and 7 are When the hooks 3A and 3B come into contact with the lower base end portions 5C and 5C, they stop.

  In this manner, when the wedge K is driven, the joint P1 descends along the guide surface 4 in a horizontal posture, so that the posture at the time of lowering is not disturbed, and there is no need to manually adjust the posture of the joint P1, and the wedge K of the joint P1. The tightening and mounting operations are smooth and easy.

  Moreover, when the flanges 7 and 7 are accommodated in the lower base end portions 5C and 5C of the hooks 3A and 3B, no gap is generated between the flange 7 and the inner periphery of the opening 2, and as a result, the sheet The stopper 8 has no play, does not move from side to side, and does not rattle, and can be stably attached to a predetermined position, for example, the center position of the sheet stopper 8 to hold and reinforce the sheet stopper 8.

  In the present embodiment, the wedge K is inserted into the guide hole 1C for wedge insertion from the crossing direction orthogonal to the channel member 9, in other words, from the direction orthogonal to the plate piece 1A. Here, if the sheet stopper 8 is fixed by inserting the wedge K between the bottom plate 1B of the joint P1 and the channel member 9 in a direction parallel to the channel member 9, the wedge insertion side is inserted when the wedge K is inserted. The hook 3A is inclined downward with respect to the hook 3A on the opposite side. Therefore, a large load may be applied to the flange 7 pressed by the hook 3A on the wedge insertion side, and the flange 7 may be deformed. On the other hand, when the wedge K is inserted in the intersecting direction perpendicular to the channel material 9 as in the present embodiment, the hooks 3A and 3B on both sides simultaneously press the flanges 7 and 7 on both sides. The load is not concentrated and deformation of the flange 7 can be prevented.

  However, in this embodiment, the wedge K is driven into the wedge insertion 1C from the direction orthogonal to the channel material 9, but it is parallel to the channel material 9 between the channel material 9 and the bottom plate 1B of the joint P1. The sheet stopper 8 may be fixed by inserting a wedge K in the direction.

  As described above, according to the joint P1 of FIG. 1, the flange 7 can be smoothly inserted to the lower end corner 5A of the opening 2 along the guide surface 4, and further, when the joint P1 is pushed down by the wedge K, The support piece 1 can be smoothly lowered along the guide surface 4 and finally the outer end of the flange 7 can be brought into contact with the lower base end portions 5C of the hooks 3A and 3B to be fitted.

  In this state, as described above, no gap is generated between the side surface of the flange 7 and the inner side surface of the opening 2, and the joint P2 itself can be prevented from moving in the lateral direction. 8 can be positioned at an appropriate position in the lower center.

  Therefore, when the upper surfaces of the pair of flanges 7 and 7 are held in contact with the lower surfaces of the hooks 3A and 3B, the joint P1 is restricted from moving in the lateral direction, and an external force acts on the seat stopper 8 and the joint P1. However, these members do not move left and right and do not generate backlash. Therefore, the joint P2 does not loosen, and the sheet stopper can be stably and firmly held.

  As a result, it is possible to prevent the sheet S held by the sheet stopper 8 from being distorted or broken.

  6 to 8 show a state in which the sheet stopper 8 is fixed to the channel member 9 using the joint P1.

  This state is apparently the same as the above-mentioned reinforcing state, but the procedure of the joint P1 attachment step and the sheet S extension step is completely different.

  In this state, the sheet stopper 8 is not held by the channel member 9 and the sheet S is not stretched, and the sheet stopper 8 is fixed to the channel member 9 by the joint P1 from the beginning. Is spread through the sheet stopper 8.

  The steps of this procedure are a step of placing the sheet stopper 8 on the fixed channel member 9 (first step), and a step of inserting the joint P1 while inclining the joint P1 to the lower side of the channel member 9 (second step). Step), a step of inserting the collar 7 of the sheet stopper 8 while being inclined into the opening 2 (third step), and a wedge K is driven into the wedge insertion groove 1D below the opening 2 A step (fourth step) of holding the collars 7 and 7 of the sheet stopper 8 between the wedge K and the hooks 3A and 3B, and a step of finally holding the sheet S by the sheet stopper 8 (fifth step); , Is made up of.

  Through the above process, the sheet stopper 8 can be fixed to the channel member 9 by the joint P1 alone. Then, in the step of inserting the collar 7 of the sheet stopper 8 into the opening 2, the collar 7 enters while being guided by the guide surface 4, and then rises due to the tightening force of the wedge K to lower the lower bases of the hooks 3A, 3B. Fits in end 5C. The effect of the guide surface 4 in this case is the same as that in the reinforcing step shown in FIGS.

  When the sheet stopper 8 is fixed by driving the wedge K below the opening 2, the wedge K is positioned on the upper surface of the channel member 9. As a result, as shown in FIG. 7, the expansion position of the sheet S can be raised upward by the height of the wedge K, and even if the sheet S is pushed downward by an external force such as wind pressure, the channel material 9 It is possible to prevent the occurrence of problems such as making contact judgments.

  9 to 13 show a joint P2 according to another embodiment of the present invention and a state in which the joint P2 is used for reinforcement.

  The basic structure including the opening 2 of the joint P2, the hooks 3A and 3B, and the guide surface 4 is the same as the basic structure of the joint P1 according to the embodiment of FIG.

  However, although the hooks 3A and 3B are slightly different in the shape in which the wide ear pieces are provided in the horizontal direction, the operational effects of the basic structure are exactly the same.

  Moreover, although the joint P1 of FIG. 1 is comprised by a pair of plate pieces 1A and 1A which the support piece 1 opposes, the joint A2 which concerns on embodiment of FIG. 9 is the point that the support piece 1 is one piece. It is different.

  That is, as shown in FIG. 9, the joint P2 has a support piece 1 comprising a single plate piece 1E and a contact plate 1H provided horizontally at the lower end of the plate piece 1E, and the plate piece 1E and the contact plate 1H are connected to each other. The holes 10 and 11 for inserting screws are respectively formed.

  The joint P2 is used for reinforcement, but can also be used for fixing.

  11 to 13 show a state in which the sheet stopper 8 is reinforced through the joint P2.

  In this case, in the state where the sheet stopper 8 is fixed to the channel member 9 with the screw V in advance, when it is visually confirmed that the holding force of the screw V is reduced, the joint P2 is connected to the channel member from the lower side of the sheet S. The sheet stopper 8 is fixed to 9 and reinforced in addition to the holding force of the screw V.

  While the joint P2 is inclined, the opening 2 is fitted into the flanges 7 and 7 of the sheet stopper 8, and then the joint P2 is moved toward the channel member 9 to bring the plate piece 1E into contact with the outer surface of the channel member 9, and The plate piece 1 </ b> E is manually pulled downward to hook the backing plate 1 </ b> H on the lower surface of the channel material 9.

  Thereafter, as shown in FIG. 11, the plate piece 1E and the contact plate 1H are fixed by driving the screws V1 into the screw insertion holes 10 and 11, respectively, and the hooks 3A and 3B. , 7 is pressed in and the sheet stopper 8 is reinforced.

  In the above process, when the plate piece 1E is pulled down, the flange 7 is guided to the guide surface 4, in other words, the plate piece 1E is lowered along the guide surface 4 and finally the lower base ends of the hooks 3A and 3B. Stop at position 5C. As described above, the function and effect in this case are the same as the function and effect of the joint P1 in FIG.

This is different from the joint P2 according to the embodiment of FIG. 9 in that the hooks 3A and 3B are formed in a square shape and are not provided with an ear piece, but the other structure, function and effect are the same as the joint P2 of FIG. Therefore, details are omitted.

  16 to 20 show a joint P4 according to another embodiment of the present invention and a state in which the joint P4 is used for fixing.

  The basic structure including the opening 2 of the joint P4, the hooks 3A and 3B, and the guide surface 4 is the same as the basic structure of the joint P1 according to the embodiment of FIG. However, although it differs in the shape of the support piece 1 and the hooks 3A and 3B, it is exactly the same as the case of the joint P1 in FIG.

  The joint P4 is composed of a pair of opposing long and thin plate pieces 1J and 1J in which the support piece 1 is connected by a horizontal top plate 12. The joint P4 is connected to the end of the top plate 12 and the top end of the plate pieces 1J and 1J.
