[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 cover material is protruded from a building body provided with a gap to the gap side, and both cover materials are overlapped to cover the gap. .

[0002]

2. Description of the Related Art In general, an expansion joint has a plurality of holders attached to an edge of a building frame provided with a gap therebetween at intervals, and the holder supports both ends of a cover material covering the gap. When both buildings were displaced relative to each other due to vibrations or differential settlement, a structure was adopted that responded well to the displacement. However, the conventional cover material was not very good when the relative displacement of the building frame was large.

[0003] Conventionally, a gap between the building bodies has been covered with a single cover material. Therefore, if the gap between the building bodies is large, the width of the cover material is also widened, and the weight of the cover material makes the work troublesome. In addition, an excessively wide cover material has a drawback that the appearance is inferior.

[0004]

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

[0005]

Means for Achieving the Object In order to achieve the above object, the expansion joint according to the present invention comprises a holding member disposed along each edge of a building frame provided with a gap, and each holding joint is provided with a holding member. its along the longitudinal direction of the member
A plurality of holders are arranged at intervals, one end of each of the holders is supported by an elastic support member at a position slightly away from the gap between the building bodies , and the other end of each of the holders together with elastically by the support so as to be hooked up from the holding member of the support member in a state of being suspended in the holding member, the above-mentioned holder between the building skeleton
The cover material protrudes toward the gap side of the building , and one of the cover materials has a recess formed at a position corresponding to the gap between the building structures , and the bent portion of the other cover material slides in the recess. The cover members are movably stored so that the surfaces of the cover members on both sides are substantially flush.

[0006]

According to the above construction, when the building frame is relatively displaced in the direction of approaching or separating from each other due to vibration, uneven settlement, etc., it slides at the overlapping portion of both cover materials. The displacement can be dealt with. Also,
When the building frame is relatively displaced in the opposite direction parallel to each other, the two cover members are separated from each other from the overlapping portion or are in a state of being strongly pressed against each other. In the latter case, the holder itself, which is supported by the support member, is lifted up from the holding member and displaced in the direction, so that no excessive force is applied to the cover material and the displacement of the building frame is prevented. It can respond well. Further, since the gap between the building bodies is covered with two sheets of cover material, even if the gap is wide, it is sufficient to attach the sheets one by one, so that the weight of the cover material does not hinder the work, and Appearance appearance is also good.

[0007] In addition, one end of each holder is located between the building frames.
It is supported at a position slightly away from the gap, and the other end is
Because it is suspended on a holding member,
The cover material can be sufficiently supported with force, and
Height position of holder when mounting is determined by holding member
Therefore, the work of adjusting the height position becomes easy.

[0008] Further, the concave portion of one cover material is inserted into the concave portion of the other cover material.

FIG. 1 is a sectional view of an expansion joint. Reference numeral 1 denotes a building body provided with a gap S therebetween. A substantially L-shaped elongate holding member 2 is fixed along each edge of the building frame 1, and both ends of the water stop plate 3 stretched in the gap S are held by the holding member 2. Have been. In addition, a plurality of holders 4 are arranged at intervals on each edge of both building structures 1. As shown in FIG. 2, the holder 4 has a holder body 4a in which an insertion groove 7 is formed by opposing pieces 5 and a bottom part 6 projecting from both sides to face each other, and is pressed into the insertion groove 7 from an end of the holder body 4a. A holder piece 4a
A support piece 9 protruding toward the gap S is press-fitted into the insertion groove 7 and fixed. One side of the holder main body 4a is supported on the upright portion 2a of the holding member 2, and the other end of the holder body 4a has the tip of a hanging portion 8a formed together with the mounting portion 8 on the fixed piece 8 abutted on the surface of the building frame 1. In this state, it is supported on the building body 1 by a screw 11 (support member) with a holding spring 10 in the form of a leaf spring (or another spring such as a coil spring). The holding spring 10 is formed in a mountain shape. Due to the elasticity of the holding spring 10, the holder 4 is supported so as to be able to rise from the surface of the building frame 1.

Next, the gap S is covered with a pair of cover members 12. One side end of each cover member 12 is bent in a Z-shape, and the bent end portion 13 is fixed to an end fixing piece 8 mounting portion 8b of each holder 4 by a screw, a rivet 14, or the like. The two cover members 12 overlap at substantially the center of the gap S to cover the gap S.
An airtight material 15 is attached to the bent portion 13 at the end of the cover material 12 on the outside to prevent a gap from being formed between the overlapping portions of the two cover materials 12. In addition, the inside cover material 1
The second end is also bent to the opposite side to the end of the outer cover member 12, and is further supported by a support piece 9 protruding from the holder 4 for fixing the outer cover member 12.

In the expansion joint having the above-mentioned structure, when the building frame 1 is relatively displaced in the direction A (the direction of approaching or separating from each other) in FIG. Because it slides
The displacement can be dealt with. When the building frame 1 is relatively displaced in the direction B (the opposite direction parallel to each other), the two cover members 12 are separated from each other from the overlapping portion, and
Alternatively, they are in a state of being strongly pressed against each other. In the latter case, the holder 4 itself is displaced in the floating direction due to the elasticity of the holding spring 10, so that an unreasonable force is not applied to the cover member 12, and the displacement of the building frame 1 can be appropriately handled. . Further, since the gap S between the building bodies 1 is covered by the two cover members 12, even if the gap S is wide, it is sufficient to mount the cover members one by one.
The weight does not hinder the work.

In addition, one end of each holder 4 is located between the building frames.
Is supported at a position slightly away from the gap S, and the other end is maintained.
Since it is suspended on the holding member 2, it is small due to the principle of leverage.
With sufficient force, the cover material 12 can be sufficiently supported.
In addition, the height position of each holder 4 at the time of mounting is determined by the holding member.
The height position is easily adjusted.

Further, one cover member 12 has a concave portion
The folded portion 13a of the cover material is slidably housed and
Since the surface of the cover material 12 is made substantially flush,
The appearance is improved.

FIG. 3 shows an application example in which two building frames 1 form a corner. In this case, the supporting piece 9a and the cover member 12a on one of the frames 1 are bent in accordance with the state of the corner. What is necessary is just to form. The members denoted by the same reference numerals as those in FIG. 1 indicate the same members as those in FIG. 1 and the description is omitted.

FIG. 4 shows another example of an expansion joint, in which a holder 4 is supported by a holding member 2 of a water stop plate 3. That is, the screw holding groove 16 is formed in the holding member 2, and the screw holder 17 of the screw 11 with the holding spring 10 is inserted into the screw holding groove 16. If the head of the screw 11 is rotated, the holder 4 is supported by the screw 11 so as to float up. Therefore, according to this example, the position of the screw 11 almost coincides with one of the support portions of the holder 4, so that the holder 4 can be easily moved. The other configurations are the same as those of the above-described embodiment, and are denoted by the same reference numerals, and description thereof will be omitted.

FIG. 5 shows an example in which the same holder 4 is attached and the building frame 1 constitutes a corner. In this case, the support piece 9a and the cover member 12a of one frame 1 are inserted. What is necessary is just to bend and form according to a corner state. 3 denote the same members as in FIG. 3, and a description thereof will be omitted.

As shown in FIG. 6A, the fixing member 18 is press-fitted into the end of the holder body 4a, and the bent end of the cover material 12 is inserted into the fixing member 18. 13 may be screwed and fixed, and the airtight material 15 may be attached to the bent end portion 13 or, as shown in FIG. The member 18 is pressed into the engagement groove 19
Alternatively, the bent end portion 13 of the cover member 12 may be configured to be engaged and fixedly engaged.
