BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large-gap extension joint device for covering a gap of a frame appearing on a wall surface of a building.

[0002]

2. Description of the Related Art Since a building is constantly distorted due to expansion and contraction due to temperature change, uneven settlement, earthquake and the like, a gap structure is configured as a means for preventing the destruction of the building caused by the distortion. Since this gap also appears on the wall surface, an expansion joint is used as a structure that covers the gap so that it can be expanded and the level difference can be absorbed during use.

Conventionally, as this type of expansion joint, as shown in FIG. 4, frame bases 50, 50 are fixedly provided on a wall surface with a gap G between buildings, and the frame bases 50, 50 are fixed. In general, a structure in which a covering plate 51 is fixed to a frame base 50, 50 so as to be slidable in the width direction via a suspending member 52 which is stretchably mounted between the frame bases 50, 50 has been used.

[0004]

However, in recent years, when the size of the strain absorbing gap is increased with the increase in size of the building, the conventional configuration requires about twice the width as the gap G increases. Since the cover plate 51 is provided on the wall surface, the front structure of the expansion joint breaks the design of the building, which is not preferable in terms of architectural design.

The present invention has been made in view of the above problems, and has as its object to provide an expansion joint device having a new structure in which the front structure does not become wider than the gap width, especially for a large gap. It is.

SUMMARY OF THE INVENTION An expansion joint device for a large gap according to the present invention is an expansion joint device provided in a strain absorbing gap appearing on a wall of a building. A pair of frame bases which are fixed to the outer wall edge facing surface of the skeleton and a plurality of ribs are provided on the opposite surface, and the outer edge sides are fixed to the both frame bases respectively, and have a substantially quarter width. A pair of cover plates protruding and facing each other in a direction to cover the gap, a central plate positioned on the back of the cover plate and suspended via suspending means formed between ribs of the frame bases, A sliding cover plate consisting of side plates laminated so as to be slidable in the width direction and positioned on both sides of the plate, and the suspending means, the central plate having one end on each of the ribs of the frame bases. One end is pivotally connected to a connecting portion of a center plate suspension connecting rod pivotally connected to one end, and both side plates have one end connected to the one end. A suspension type structure in which the other end is pivotally connected to the connecting portion of the side plate suspension connecting rod pivotally connected to the rib of the frame base at the other end thereof and the pivotal connection portion of the central plate suspension connection rod. The main point is that it has been made.

It is preferable that the frame base be pivotally mounted on hinge receiving bases fixed to the outer wall facing surfaces of the two frames facing each other with a gap therebetween.

[0008]

According to the above construction, the sliding covering plates located on the back surfaces of the two cover plates are suspended by the hanging means constituted by the connecting rods so as to be able to expand and contract the width of the sliding covering plates. The gap can be covered by the cover plate and the sliding cover plate by appropriately selecting the variable of its own width and the sliding range of the cover plate and the sliding cover plate.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an expansion joint device for a large gap according to the present invention; FIG.

Reference numerals 1 and 1 denote hinge receiving bases made of an aluminum material fixed on the outer wall edge-facing surfaces of the two frame members a, which are opposed to each other with a gap G interposed therebetween.
The hinge port 3 rising in the shape of a letter is formed in the longitudinal direction, and is fixed to the facing surface by an anchor bolt 4 embedded in the frame a.

The hinge ports 3 of the two hinge receiving bases 1 and 1 respectively have frame bases 5 and 5 made of an aluminum material.
A column-shaped hinge ridge 6 provided on the outer edge of the cylindrical member 5 is rotatably fitted, and has a degree of freedom of tilting in the direction of arrow A. The two frame bases 5 are located on the inner edge, and three ribs 7, 8,
9 and has a substantially E-shaped cross-section, and a cover plate fixed rib 10 is integrally formed on the front edge, and is erected in the direction in which the gap G extends. It is a formed water stop plate mounting rib.

The cover plate fixing ribs 1 of the frame bases 5 and 5
0 is a cover plate 1 made of aluminum material
2 and 12 fix the outer edge via a screw 13 and
The four sides project from each other in a direction covering the gap G by approximately a quarter width and are opposed to each other. It is suspended via the suspension means 20 constituted between the nine. The sliding cover plate 15 has side plates 19 formed of a front plate 17 and a rear plate 18 on both edges of a center plate 16.
Are integrated so as to be slidable in the width direction indicated by arrow B.

The suspending means 20 is a central plate suspension connecting rod 2 having one end pivotally connected to each of the ribs 8 via bolts 21.
2 and 22 and the center plate 16 are pivotally connected via screws 23, one of which is connected to the rib 18 via bolts 24, and the other is connected to the center plate 16 via screws 23. One end is pivotally connected to the other end of the both-side plate suspension connecting rods 25, 25 and the substantially central portion of the rear plate 18 of the side plate 19 via a screw 26. The side plate suspension connecting rod 25 is provided so as to be inclined with respect to the direction in which the gap G extends, and is disposed with an appropriate gap.

In the figure, b denotes a surface material adhered to the surface of the frame a, and a gap between the surface material b and the cover plate 12 is filled with a caulking material c made of a soft resin. Is not hindered. Reference numeral 27 denotes a water stop plate fixed between the water stop plate mounting ribs 11.

According to the above construction, the sliding cover plate 15 located on the back surfaces of the two cover plates 12, 12 via the suspending means 20 constituted by the center plate suspending speed rod 22 and the side plate suspending speed rod 25. Is suspended so as to be able to expand and contract the width of the plate, so that the amount of radiation caused by the central plate 16 and the side plates 19 and 19 of the sliding cover plate 15 itself and the sliding of the cover plates 12 and 12 and the sliding cover plate 15 By properly selecting the range, the gap G is set to the cover plate 12,
12 and the sliding cover plate 15 can cover the gap width.

[0016]

As described above, the expansion joint device for a large gap according to the present invention is composed of a plurality of plate members in which a sliding cover plate adjusted on the back side of the cover plate is slidably laid in the width direction. The expansion joint can be provided inside the gap by suspending so as to expand and contract through the suspending means, and the front structure does not become wider than the gap width. The characteristic of the present invention is that the unfavorable influence of the expansion joint can be reduced.
