Abstract

PURPOSE:To prevent weight of a over material from causing a trouble to work and to improve external appearance by gradually displacing a plural number of the cover material in accordance with displacement of a building body, favourably corresponding to larger displacement by this, covering a gap between the building bodies with the cover material and possibly applying the cover material piece by piece even when the gap is wide. CONSTITUTION:Side holders 4a, 4a on both sides arranged along respective end edges of building bodies facing against each other are reciprocally positioned face to face against each other. A central holder 4b is held free to slide in the cross direction of a gap S against at least one of the side holders 4a, 4a. Cover materials 12a, 12a, 12b are fixed on each of the side holders 4a, 4a, and both of the side cover materials 12a fixed on at least one of the side holders and the central cover material 12b fixed on the central holder 4b are polymerized free to slide.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an expansion joint in which a gap between opposing building frames is covered with a divided cover material.

[0002]

2. Description of the Related Art Generally, in an expansion joint, a plurality of side holders are attached to an edge of a building body provided with a gap, and both side ends of a cover material covering the gap are attached to the side holders. It was supported, and a structure was adopted that responds well to the relative displacement of both building skeletons due to vibrations or differential settlement. However, the conventional cover material does not respond well when the relative displacement of the building frame is large.

Further, conventionally, one cover material covers the gap between the building skeletons. Therefore, if the gap between the building skeletons is wide, the width of the cover material is wide, and the weight of the cover material makes the work troublesome.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks and to provide an expansion joint having excellent adaptability to relative displacement of the building frame.

[0005]

In order to achieve the above-mentioned object, the expansion joint according to the present invention has a plurality of side holders spaced from each other along each edge of the building frame which is opposed to each other with a gap. Are arranged, and the side holders on both sides are made to face each other and projected to the gap side,
A central holder is disposed between the side holders on both sides, the central holder is slidably held in the width direction of the gap with respect to the side holders on both sides, and a cover material is fixed to each side holder, It is characterized in that the side cover members fixed to the side holders on both sides and the central cover member fixed to the central holder are slidably polymerized to cover the gap.

Further, in the expansion joint, the central holder is fixed to the one side holder and is held slidably in the width direction of the gap with respect to the other side holder, and a cover material is attached to each holder. The side cover material fixed and fixed to the other side holder and the central cover material fixed to the central holder may be slidably polymerized to cover the gap.

[0007]

According to the above construction, when the building skeletons are relatively displaced in the direction of approaching or separating from each other due to vibration, differential settlement, etc., the central holder slides with respect to the side holders on both sides. Since the central cover material slides on both side cover materials at the same time, it is possible to cope with the above displacement satisfactorily. Further, when the building skeletons are relatively displaced in opposite directions parallel to each other, the side holders on both sides and the side cover materials on both sides are displaced in the same direction, and the central holder also follows the side holders on both sides. Since it is displaced, the central cover material is also displaced following the central holder. As described above, the three cover members are gradually displaced, so that it is possible to favorably cope with a large displacement. Furthermore, since the gap between the building frames 1 is covered by the three cover materials, even if the gap is wide, it is sufficient to mount them one by one, so the weight of the cover material does not hinder the work. In addition, the appearance is also good.

The central holder is fixed to the one side holder, and is held slidably in the width direction of the gap with respect to the other side holder, and a cover material is fixed to each holder, and the other side holder is fixed. Even when the side cover material fixed to the side holder and the central cover material fixed to the central holder are slidably overlapped to cover the above-mentioned gap, the same effect can be obtained.

1 is a sectional view of an expansion joint. Reference numeral 1 indicates a building frame that faces each other with a gap S therebetween. A substantially long holding member 2 is fixed along each edge of the building body 1, and the holding member 2
Both side ends of the water blocking plate 3 stretched over the gap S are held by. Further, a plurality of side holders 4a, 4a on both sides are arranged at intervals at each end edge of both the building skeletons 1. The side holders 4a and 4a on both sides include a side holder body 8 in which an insertion groove 7 is formed by a facing piece 5 and a bottom portion 6 which project from both sides of the holder 4a so as to face each other as shown in FIG.
The side holder body 8 includes a fixing piece 9 which is press-fitted into the insertion groove 7 and attached, and the side holder body 8 abuts the tip of the hanging portion 9a formed on the fixing piece 9 against the surface of the building body 1. Alternatively, they are supported on the holding member 2 in a state of being brought close to each other, and are supported on the building frame 1 by screws 11 having a holding spring 10 such as a leaf spring (or a coil spring or the like). Leaf spring 1
0 is formed in a mountain shape. Due to the elasticity of the holding spring 10, the side holders 4 a, 4 a on both sides are supported so as to be able to float up from the surface of the building frame 1.

A central holder 4b is disposed between the side holders 4a on both sides, and both ends of the central holder 4b are slidable in the insertion groove 7 of the side holders in the width direction of the gap S. Held in.

Next, the gap S is defined by the holders 4a on each side.
Both side cover materials 12a, 12a fixed to 4a, 4b and a central cover material 12b are covered. One side end of each side cover material 12a, 12a is bent into a Z shape,
The bent end 13 is fixed to the end fixing pieces 9 of the side holders 4a and 4a on both sides by screws, rivets 14 and the like. The other end of each side cover member 12a, 12a has a gap S.
Bent to the side. On the other hand, the central cover material 12b is fixed to the central holder 4b with screws 14, rivets and the like, and both side cover materials 12a and
A bent portion 16 that is bent so as to engage with the bent portion 15 of 2a is formed. Then, both side cover members 12a, 12a fixed to the side holders on both sides and the central holder 4b.
The central cover material 12b fixed to the above is slidably polymerized to cover the gap S.

In the expansion joint having the above-mentioned structure, when the building frames 1 and 1 are relatively displaced in the direction A (direction toward or away from each other) of FIG. 1 due to vibration, differential settlement, etc., the central holder 4b has both sides. Side holder 4
Since the center cover material 12b slides on both side cover materials 12a, 12a at the same time,
It is possible to favorably deal with the above displacement. When the building frame 1 is relatively displaced in the B direction (opposite directions parallel to each other), the side holders 4a and 4a on both sides and the cover materials 12a and 12a on both sides are displaced in the same direction, and the central holder is also displaced. Since 4b also follows the side holders 4a and 4a on both sides and is displaced, the center cover material 12b also follows the center holder 4b and is displaced. In this way, the three cover members 12a, 12
It is possible to favorably cope with a large displacement by displacing a and 12b little by little. When the building skeletons 1 and 1 are tilted, it can be considered that the A direction and the B direction are combined. Further, since the gap S between the building frames 1 is covered by the three cover members 12a, 12a, 12, even if the gap S is wide, it is sufficient to mount them one by one.
The weight of the cover material does not hinder the work, and the side edges of the cover materials 12a, 12a, 12b appear as a triple line, so that the appearance is good.

The mounting manner of the side holders 4a, 4a on both sides to the building frame 1 is as shown in FIG.
At the end of the building frame 1 on the side of the gap S, the holding member 1 for the water blocking plate 3
7 is attached to form a rising edge 18 on the holding member 17, one end of each of the side holders 4b and 4b on both sides is supported on the rising edge 18, and a hanging portion 9a at the other end is attached to the building body 1 surface. And the central portion of the holding spring 10
It may be configured such that the building body 1 is supported by the attached screws 11.

FIG. 4 shows an application example in which two building frames 1 and 1a form an inner corner. In this case, one of the frame 1a is used.
The side holder 4a on the side and the side cover material 12a may be bent and formed in accordance with the entering corner state. In addition, the members indicated by the same reference numerals as those in FIG. 1 are the same members as those in FIG. 1, and the description thereof will be omitted. Of course, the side holders 4a and 4a on both sides may be attached as shown in FIG.

Regarding the fixing of the side cover material 12a, as shown in FIG. 5 (a), the fixing piece 9 of the fixing member 19 is press-fitted into the end portion of the side holder body 8 and the side cover member 12a is fixed. The bent end 13 of the material 12a may be fixed by screwing, and the airtight material 20 may be attached to the bent end 13, or as shown in FIG. The fixing member 22 having the engaging groove 21 may be press-fitted, and the bent end portion 13 of the side cover material 12a may be tapped into the engaging groove 21 to press-fit and fix each other.
