Description

[Detailed description of the invention] (Industrial application field) The present invention includes a plurality of foundation members that are connected to each of the building frames facing each other along the gap between these building frames, and a A closure attachment device for an expansion joint that improves the relationship between the closure provided at the continuous portion of the cover material and a base member in an expansion joint consisting of a plurality of cover materials arranged in series. Regarding.

(Prior art) Expansion joints are generally installed between building frames that are located close to each other and facing each other, but building frames facing each other in this way are Due to vibrations, uneven subsidence of the ground, and expansion and contraction due to temperature changes during the day and night or season, the expansion joints fluctuate in different directions and their relative positions shift accordingly. Usually, long metal support members are fixed as base materials to both building frames, facing each other along the opposing gaps of the building frames, and then one support member and the other support member are fixed to each other as a base material. It is constructed by attaching a shaku cover member in a freely movable manner. A drainage portion may be added to the cover material as required. The opposing forms of building frames are roof-to-roof, floor-to-floor,
When they are on the same plane, such as walls, or when they form a corner at a predetermined angle, such as when a roof and a wall, a floor and a wall, or a wall and a wall, etc. There are various cases, such as the case where the expansion joint is configured accordingly. However, in any case, the above basic structure of the expansion joint remains the same.

Next, an expansion joint is constructed by sequentially arranging a plurality of elongated structural members in the longitudinal direction, and the gap formed between adjacent structural members at this continuous part is , are closed off by a closing body to prevent the intrusion of wind, rain, rainwater, etc.
For example, as shown in Japanese Utility Model Application Publication No. 58-9406, a plurality of supporting members are provided in series along the gap between the opposing building frames, and a plurality of support members are provided across the supporting members. The base member formed by the covered cover material, each support member, and the draining member is each configured by a plurality of members connected in series,
A closure is provided at the end of each component. The purpose of providing each component with a closing body is to better respond to changes in the structure due to vibrations, temperature changes, and the like.

However, the above structure alone is not sufficient for blocking rain by the blocking body. In other words, the problem with the closing body of the base member is the gap between it and each building frame, and the problem with the closing body of the cover material is the gap between the base member or the closing body attached to the base member. Become. The former can be solved by caulking, but in the latter case, the gap between the cover member and the base member (draining member in the above publication) was far apart, so rainwater could leak through this gap. It was not possible to prevent the blown rainwater from further infiltrating through the gap in the base member or the closing member attached to the base member.

(Purpose of the invention) The present invention solves the above-mentioned drawbacks, and in particular can maintain the closing body stably at all times regardless of fluctuations in the building frame. The object of the present invention is to provide an expansion joint closure mounting device that achieves good airtightness between the expansion joint and the roof and is excellent in rain protection.

A cover material 33 having a dimension and shape is fixedly attached so as to be freely movable. In this example,
The support members 31 and 38 constitute a base member.

The above expansion joint toys, B, C, and D are constructed by consecutively arranging elongated unit components such as a support member, a cover material, and a draining part in the same direction. It is connected to the expansion joint at the corner C1 of the building blocks A and B,
The expansion joint is connected to the expansion joint at the corner C2, and the expansion joint is connected to the expansion joint at the corner C3. Then, the gap created in these continuous parts is closed by the closing body.

Next, the attachment of the closing body to each continuous portion will be explained.

First, in the expansion joint toy, the drain section 5 that is attached to the support member 1 fixed to the standing wall A1 of one building frame is connected to the closure body 10.
It is connected to another draining part 5 via 1. Note that the closing body 101 may be configured to be attached to the front side of the draining portion 5. The same applies to the other closing bodies described next.

Next, the draining section 6 attached to the other building frame B1 is connected to the other draining section 6 via the closing body 102. Although this closing body 102 is not visible in FIG. 2 because it is arranged on the opposite side of the holder 15 when facing the figure, it is also attached in the same manner as the aforementioned closing body 101. Furthermore, the cover material 3 and another cover 3 connected to this cover material are

The only forces exerted in different directions on 2 and 103 are due to expansion and contraction of adjacent expansion joint components 1, 2 and 3 due to temperature differences. This force is the blocking body 101, 10
2 and 103 can be easily absorbed by attaching them in a non-fixed state, such as by loosely locking them to at least one of the adjacent expansion joint components. Therefore, the closing bodies 101, 102, and 103 can respond favorably to changes in the frame structure, and can stably and reliably close the gap between the continuous parts.

Further, one end of the closing body 103 of the cover material 3 is in contact with a drainage portion 6 that constitutes a base member together with the airtight material 50. In this way, the cover material 3 and the draining part 5
Since the closing body 103 and the airtight material 50 of the cover material 3 are in contact with the drainage part 6, the closing body 103 of the cover material 3 can be removed without attaching an airtight material to the closing body 103 itself. It is possible to achieve good airtightness between the base member (draining portions 5 and 6) and to prevent rain. The same applies to other examples.

In addition, in the expansion joint, the support member 31 fixed to the building frame B2
is connected to another support member 31 via a closing body 105. The same applies to the frame A4.
Further, the cover material 33 is connected to another cover material 33 via a closing body 106. Both ends of the closing body 106 are in contact with the draining portion 6 that constitutes the base member together with the airtight material of the cover material 33.

Furthermore, in the expansion joint, the support member 38 on the building frame A6 side is connected to another support member 38 via the closing body 107,
The support member 31 on the building frame B2 side is the closing body 105
The cover member 33 is connected to another support member 31 via a cover member 106, and the cover member 33 is connected to another support member 33 via a closing body 106. One end of the closing body 106 is connected to the support member 38 together with the airtight material of the cover material 33.
In addition, the other end is in contact with the closing body 105 of the support member 31.

Next, the expansion joints 1 to 2 are connected to each other via closing bodies 108, 109, and 110 at the corner portions C1 to C3 of the building frame. In this case as well, the closing bodies 108, 109,
110 is attached to the above-mentioned closing bodies 101 to 1.
It is exactly the same as the case of 07. However, in each of the corner portions C1, C2, and C3, the structures of the cover materials of the expansion joints that are arranged in series with each other are different, and the closing body has a structure that corresponds to this difference.

In addition, in the corner part C2, the ends of the drainage parts 6, 6 of the expansion joint and the support member 31 of the expansion joint,
A corner cap 112 is also attached to the end of the support member 38 of the expansion joint at the corner C3. This cap is also one of the blocking bodies.

The form of the corner part is not limited to the above example,
