It relates to the joint structure.
[0002]
[Prior art]
Conventionally, the following joint structure has been adopted when connecting adjacent housings through a gap extending in the vertical and horizontal crossing direction.
That is, a building 74 in which a parapet 72 is provided on a rooftop 71 as shown in FIG. 9 and a tower 73 is erected, and a building 76 whose outer wall surface 75 is higher than the rooftop 71 are separated by a gap V. In the horizontal direction on the outer wall surface 75 of the building 76, the side cover material 79 of the expansion joint 78 is held by the notch groove 77 in one side end portion. The upper surface of the frame gap is closed with the cover material 79, and at the same time, the portion of the outer surface of the tower 73 where the horizontal cover material 79 abuts is cut to insert the base side edge of the horizontal cover material 79. The horizontal cover member 79 is fixed to the tower 74 by caulking the portion 80, and the horizontal cover member 79 covers the upper surface of the gap extending in the horizontal direction while closing the vertical gap in the horizontal cover member 79. The top of 79 The inner cover material 81 is provided, and the expansion joint 82 is enforced by contacting the lower end of the lower cover material 81 with the upper surface of the horizontal cover material 79 and closing with a caulking material. It was.
[0003]
[Problems to be solved by the invention]
Originally, by implementing the expansion joint 78 at the corner between the building 74 and the building 76 in this way, it is possible to absorb the fluctuations of the building and prevent the intrusion of rainwater into the frame gap. First, since the end portion of the lateral cover material 79 was inserted into the notch portion formed on the outer side surface of the tower 73 as described above and the caulking process 80 was performed here, both the buildings 74 and 76 were in the longitudinal direction of the frame gap (this direction) , Hereinafter referred to as “Y direction”), the horizontal cover material 79 itself may be damaged, and it cannot be said that the expansion joint function is sufficiently exhibited.
[0004]
In view of this, the present invention has improved the above expansion joint structure in order to solve the problems of the conventional expansion joint structure of this type, and has entered rainwater into the gap extending in the vertical and horizontal crossing directions formed between adjacent housings. It is an object of the present invention to provide an expansion joint structure that can reliably prevent the above-described problem and can absorb the fluctuation in the Y direction of the building.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention connects adjacent housings via a gap extending in the crosswise direction and closes the longitudinally extending housing gap in an expansion joint structure that closes the housing gap. The drainage cover material is arranged between the vertical cover material and the horizontal cover material that closes the frame gap extending in the horizontal direction. That is, the present invention connects the adjacent housings through a gap extending in the longitudinal and transverse crossing directions, and in the expansion joint structure that closes the housing gap, the vertical cover material that closes the longitudinal gap extending in the longitudinal direction, A drainage cover material that is integrally stretched so as to cover the frame gap extending in the horizontal direction from the lower end of the vertical cover material, and a horizontal cover that covers the frame gap extending in the horizontal direction with a slide insertion part on the lower surface side. The vertical cover material is attached to one housing so as to be rotatable in the horizontal direction, the base end side portion of the horizontal cover material is slidably inserted into the slide insertion portion of the drainage cover material, and the horizontal cover material One side edge was fixed to one housing.
[0006]
As a result, it is possible to close the frame gap extending in the vertical direction with the vertical cover material, and to close the frame gap extending in the horizontal direction with the horizontal cover material and the drainage cover material. Rainwater intrusion into the gap extending in the crosswise direction can be reliably prevented. In addition, when the adjacent casings change in the longitudinal direction of the gap between the casings (this direction is referred to as “Y direction” throughout the specification), the vertical cover member rotates in the horizontal direction following this. At the same time, the drain cover material formed integrally with the vertical cover material also rotates in the horizontal direction, and the horizontal cover material is fixed to the housing only at one edge, and can slide on the drain cover material. Since it is inserted and arranged in the case, it is possible to slide following the variation in the Y direction of the housing. On the other hand, in the case where adjacent housings change in the housing gap width direction (this direction is referred to as “X direction” throughout the specification), both the vertical cover material and the horizontal cover material are only for one housing. Fixed, the draining cover material is not fixed to any housing, so one of the adjacent housings can fluctuate in the X direction without damaging the vertical cover material, draining cover material and lateral cover material. it can. Thus, the expansion joint structure of the said structure can absorb this, without a failure | damage | failure, even when an adjacent housing | casing changes to any direction of an X direction and a Y direction mutually.
[0007]
In the above-described configuration, for example, a water-stopping member that can be elastically deformed is attached to a side edge portion that faces the casing of the draining cover material, and the draining cover material and the casing are closely bonded to each other through the water-stopping member. Water stoppage between the drainage cover material and the housing can be ensured without hindering the rotation of the cover material.
[0008]

These are the perspective plan views which showed the operation | movement when the building frame B fluctuate | varied to the Y direction.
[0010]
For example, as shown in FIG. 3, the expansion joint structure 1 includes a side wall outer surface a of the casing A, a side wall outer surface b of the casing B, and a side wall in the adjacent casings A and B through the casing gap extending in the vertical and horizontal crossing directions. An expansion joint structure which is constructed in an entrance corner formed from the top end surface c of the parapet C formed integrally with the outer surface b and prevents rainwater from entering the frame gap, and the frame gap extending in the vertical direction A corner cover material 12 as a vertical cover material to be closed, a drainage cover material 11 integrally formed at the lower end of the corner cover material 12, and a horizontal cover material 13 to close a laterally extending housing gap It is composed of
[0011]
First, the corner cover material 12 will be described. The corner cover material 12 is bent along a corner shape composed of the side wall outer surface a and the side wall outer surface b, and further, both ends are folded toward the side wall outer surface a or the side wall outer surface b. A bent cover body 123 is fixedly backed by a pivot support piece 121, and one end of the pivot support piece 121 is connected to the outer surface a of the side wall of the housing A via a pivot section 122. It is pivotally fixed so as to be pivotable in the horizontal Z direction, and gaskets 117 and 117 are provided along both side edges of the cover body 123 in the X direction. A gap between the cover body main body 123 and a gap between the other end edge in the X direction and the side wall outer surface b are respectively closed by gaskets 117 and 117 as water-stopping members that can be elastically deformed.
[0012]
Next, the drain cover material 11 forms a notch 111 on the upper surface 110 that matches the contour of the lower end cross section of the corner cover material 12, and welds the notch 111 and the lower end of the corner cover material 12. Are joined together by an adhering means such as a top surface, a hanging surface 113 is formed on the front surface side in the Y direction of the top surface portion 110, a hanging surface 114 is formed on the front surface side in the X direction of the top surface portion 110, and Is cut out so as to substantially conform to the shape of the lateral cover member 13 to form a slide insertion portion 113a.
The drainage cover member 11 is provided with gaskets 117 and 117 as water-stopping members that can be elastically deformed along the side edges 115 and 116 facing the side wall outer surfaces a and b. The outer surfaces a and b are tightly joined and closed through these gaskets 117 and 117.
[0013]
As shown in FIG. 1, the lateral cover member 13 bends the X direction front end edge of the upper surface 130 downward to form a drooping surface 131, and raises the X direction base end edge to form a fixed edge 132. The base end edge in the Y direction is raised to form a flange 133.
The horizontal cover member 13 is inserted and disposed in the slide insertion portion 113a so that the upper surface 130 is in contact with the lower surface of the drainage cover member 11, the fixed edge portion 132 is fixed to the side wall outer surface a, and the fixed portion is sealed. And fixed. At this time, it is preferable that the lower surface of the one side hanging surface 113 of the drainage cover material 11 and the upper surface 130 of the lateral cover material 13 are arranged to slide while in contact with each other without a gap.
[0014]
In the state where the horizontal cover member 13 is inserted into the slide insertion portion 113 a of the drainage cover member 11, a gap d is secured between the X-direction front side portion of the slide insertion portion 113 a and the hanging surface 131 of the horizontal cover member 13. The gap d is set to be at least larger than the width of the gasket 117 in the X direction.
[0015]
If the expansion joint structure 1 is configured as described above, from the viewpoint of preventing rainwater intrusion into the frame gap, the gaskets are formed at both end edges in the X direction of the corner cover member 12 that covers the frame gap extending in the vertical direction. 117 and 117 are attached to prevent the intrusion of rainwater into the gap between the casings extending in the longitudinal direction because the gap with the side wall outer surface a is closed. Further, a drainage cover member 11 is disposed on the base end side of the corner of the housing gap extending in the lateral direction, and between the drainage cover member 11 and the side wall outer surfaces a and b via gaskets 117 and 117. Since the side cover material 13 for closing the laterally extending housing gap is disposed at the front end side of the entrance corner and the adhering portion with the side wall outer surface a is sealed, it is closed in the lateral direction. Prevents the intrusion of rainwater into the gaps between the bodies. Thus, it is possible to reliably prevent rainwater from entering the housing gap.
[0016]
Next, when the expansion joint structure 1 is viewed from the viewpoint of the expansion joint function, as shown in FIG. 4, when the housing B changes in the arrow Y direction, the corner cover material 12 has the pivot 122 as a fulcrum in the horizontal Z direction (see FIG. The drain cover material 11 also rotates together with the corner cover material 12 at the same time. At this time, the gasket 117 attached to the side edge portion 115 that is in contact with the housing A is deformed by its elasticity to maintain the sealing performance while maintaining the sealing performance, and in the slide insertion portion 113a, The gap d formed between the X-direction front side portion of the slide insertion portion 113a and the hanging surface 131 of the horizontal cover member 13 ensures the rotation width of the drainage cover member 11. Further, since the horizontal cover member 13 can slide within the slide insertion portion 113a of the drain cover member 11, the expansion joint structure 1 absorbs this change when the casings A and B change in the Y direction. can do.
[0017]
On the other hand, as shown in FIG. 3, when the casings A and B change in the X direction, the corner cover member 12 and the lateral cover member 13 are fixed only to the casing A side, Since neither the chassis A nor B is fixed, even if the chassis B and the parapet C are varied in the X direction, the expansion joint structure 1 is not damaged as long as it is within a certain range. This variation can be absorbed when B varies in the X direction.
[0018]
In the expansion joint structure 1, the rubber elastic sheet 2 is attached between the corner walls of the adjacent casings A and B so as to be closed and receive rainwater, or the outer side wall of the other casing B By fixing the receiving rod 3 to b, regardless of the variation between the two housings A and B, from between the outer wall surface b of the housing B and the inner wall surface of the corner cover material 12 welded by the notch 111. It can also be configured to reliably receive the rainwater that flows down.
[0019]
For example, as shown in a perspective view in FIGS. 3 and 5 and in a plan view in FIG. 6, between the longitudinal direction of the housing A and the housing B and between the lateral direction between the housing A and the parapet C integrated with the housing B. The rubber elastic sheets 2 and 2 are attached, and the elastic elasticity of the rubber elastic sheets 2 and 2 is used to follow the fluctuation in the XX ′ direction, so that the side wall outer surface a of the casing A and the casing B The space between the side end surface and the side wall outer surface c of the parapet C is closed, and flows down between the side wall outer surface b of the housing B and the inner wall surface of the corner cover material 12 erected along the notch 111 of the drainage cover material 11. It is more preferable to fix the receptacle 3 for receiving rainwater to the outer wall b of the side wall of the housing B in order to completely prevent rainwater from entering.
[0020]
That is, as shown in FIG. 5, the receiving rod 3 is formed with a seal portion mounting piece 32 and rising pieces 33, 34 raised on the rod body 31, and a guide seal portion 35 is provided on the seal portion mounting piece 32. It has been done. The receiving part 3 has a rear surface part fixed to the side wall outer surface b of the side end part of the case B, and the mounting position in the vertical direction is the upper surface of the parapet C and the side cover which are arranged orthogonally with the case B. A protrusion is formed between the material 13.
[0021]
The rainwater entering from above by the attachment of the receptacle 3 flows down directly or along the inner wall surface of the corner cover material 12, and the rainwater flowing down along the outer wall b of the side wall of the housing B is in the direction of the arrow. It is guided by the guide seal portion 35 and enters into the receptacle 3 and is drained from the receptacle 3 along the inner surface of the side wall of the parapet C on the back side of the lateral cover member 13. That is, if the receiving rod 3 is fixed on the outer wall b of the side wall B of the housing B and placed on the upper surface of the parapet C integral with the housing B, the intrusion of rainwater can be prevented completely, and the above-mentioned Since the rubber elastic sheet 2 and the cradle 3 are shielded from sunlight on the back side of the corner cover material 12 and the side cover material 13, they are more preferable because they can retain their functions for many years.
[0022]
The expansion joint structure of the present invention has a corner structure composed of one casing wall surface, the other casing wall surface, and a parapet top end surface integral with the casing wall as described above, as well as, for example, as shown in FIG. The side wall outer surface a of the housing A and the side wall outer surface b of the housing B, the top end surface e of the parapet E integrated with the side wall outer surface a, and the top end surface c of the parapet C integrated with the side wall outer surface b. Moreover, the present invention can be applied to a corner structure having a frame gap extending in the crosswise direction.
[0023]
That is, as shown in FIG. 7, instead of the corner cover member 12, a flat cover member 12 'is used as a vertical cover member, and the flat cover member 12' is pivotally attached to the gap side end surface of the side wall outer surface a. Then, the casing gap extending in the vertical direction is closed. From the lower end of the flat cover member 12 ', the drain cover member 11 is integrally formed so as to cover the gap in the horizontal direction as described above. Then, in the slide insertion portion 113a of the drainage cover material 11, the Y-direction base end side of the mountain-shaped lateral cover material 13 ′ is slidably inserted and disposed so as to ensure the gap d as described above. What is necessary is just to arrange | position so that this mountain-shaped horizontal cover material 13 'may cover the housing gap | interval which extends in the vertical direction across the top end surface e of the parapet E, and the top end surface c of the parapet C.
[0024]
Further, the horizontal cover member 13 is fitted on the top end surface e of the parapet E and the top end surface c of the parapet C so as to be fitted to cover holders 4, 4. It is fixed and attached so as to be variable in the X direction. For example, as shown in FIG. 8, if the bolt insertion hole on at least one side of the fixing surface of each cover holder 4 is a long hole 5 that is long in the X direction, that is, a loose hole, the cover holder 4 is moved in the X direction. It can be installed slidably.
