[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an expansion joint device for a large gap for covering a gap of a body appearing on a wall surface of a building.

[0002]

[Prior art]

 Since a structure is constantly distorted due to expansion and contraction due to temperature changes, unequal subsidence, and earthquakes, etc., a gap structure is constructed as a means to prevent destruction of the structure caused by the distortion, and this structure is also applied to the wall surface of the structure. Since a gap will appear, an expansion joint is used as a structure that covers this gap so that it can be expanded and sandwiched at the time of use and can absorb the level difference.

As an expansion joint of this type, conventionally, as shown in FIG. 4, frame bases 50, 50 are fixedly mounted on a wall surface with a gap G of a building interposed therebetween, and the frame bases 50, 50 are also fixed. A structure is generally used in which a covering plate 51 hung on the frame is fixed between the frame bases 50, 50 so as to be slidable in the width direction via a suspending member 52 extensible and extensible.

[0004]

[Problems to be solved by the device]

 However, as the size of the building has increased in recent years, and the strain absorbing gap has increased in size, in the above-described conventional configuration, when the gap G is increased, the covering plate 51, which requires about twice the width, is formed on the wall surface. Since it is provided, there is a problem in terms of architectural design that the front structure of the expansion joint divides the design of the building.

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

[0006]

Means for Solving the Problems The expansion joint device for a large gap of the present invention is an expansion joint to be installed in a strain absorbing gap appearing in a wall portion of a building. A pair of frame bases fixed to the facing surfaces of the edges and a plurality of ribs provided on the facing surfaces, and outer edges of the frame bases fixed to the frame bases. A pair of cover plates projecting in the direction of covering G and facing each other, and a sliding cover plate located on the back surface of the both cover plates and suspended via suspending means formed between the ribs of the frame bases. The purpose is to be composed of.

The sliding cover plate may be implemented by a laminated structure composed of a plurality of materials including a central plate and side plates that are slidable in the width direction.

Further, the suspending means is composed of a plurality of connecting rods, and both ends of each connecting rod are rotated between a frame base and a center plate of the sliding cover plate and between adjacent members composed of the center plate and the side plates. It can be implemented by freely pivoting.

[0009]

[Action]

 According to the above configuration, the sliding cover plates located on the back surfaces of both cover plates are hung so that the plate width can be expanded and contracted via the suspending means constituted by the connecting rod. The gap can be covered by the cover plate and the sliding cover plate by appropriately selecting the width variation and the sliding range of the cover plate and the sliding cover plate.

【Example】

 An embodiment of a large gap expansion joint device according to the present invention will be described below with reference to FIGS.

Reference numerals 1 and 1 denote hinge receiving bases made of an aluminum mold material fixed to the outer wall edge facing surfaces of the two frames a and a that are opposed to each other with a gap G in between. The hinge port 3 standing upright is formed in the longitudinal direction, and is fixed to the facing surface by the anchor bolt 4 embedded in the frame a. The hinge ports 3 of both the hinge receiving bases 1 and 1 are rotatably fitted with the cylindrical hinge protrusions 6 provided on the outer edges of the frame bases 5 and 5 made of aluminum mold material, respectively. And has a tilting degree of freedom in the direction of arrow A. The both frame bases 5 have three ribs 7, 8 and 9 located at the inner edge and have a substantially E-shaped cross section, and a cover plate fixing rib 10 is integrally formed at the front edge to form a gap. It is erected in the extending direction of G, and reference numeral 11 is a water stop plate mounting rib formed on the inner edge of the rib 9. The cover plate fixing ribs 10 of both the frame bases 5 and 5 are provided with cover plates 12 and 12 each made of an aluminum mold member with outer edges fixed via screws 13 and the inclined edge 14 side having a gap of about a quarter width. Suspending in which the sliding cover plate 15 is located between the ribs 8 and 9 of both frame bases 5 and 5 and is located on the back surface of both cover plates 12 and 12 so as to project in the direction of covering G and face each other. It is suspended by means 20. The sliding cover plate 15 has side plates 19 composed of a front plate 17 and a rear plate 18 formed on both edges of a center plate 16, and the center plate 16 is slidable in the width direction with respect to the side plates 19 as indicated by an arrow B. It is sandwiched and integrated into one. The suspending means 20 is configured such that both ends of the central plate suspension connecting rods 22, 22 pivotally attached at one end to the ribs 8, 8 via bolts 21 and the central plate 16 are rotatable via screws 23. One end of each of the two side plate suspension connecting rods 25, 25, one end of which is pivotally attached to the rib 18 via a bolt 24 and the other end is pivotally attached to the central plate 16 via a screw 23. The rear plate 18 has a structure in which a substantially central portion thereof is pivotally attached via a screw 26 so that the central plate suspension connecting rod 22 and the side plate suspension connecting rod 25 are oblique to the direction in which the gap G extends. It is provided, and is provided with an appropriate gap.

In the figure, b is a surface material adhered to the surface of the skeleton a, and a caulking material c made of a soft resin is filled in a gap between the surface material b and the cover plate 12, and the arrow A The structure does not prevent displacement in the direction. Further, reference numeral 27 is a water blocking plate fixed between the water blocking plate mounting ribs 11, 11.

According to the above configuration, the sliding cover plate 15 located on the back surface of both cover plates 12 and 12 via the suspending means 20 composed of the central plate suspension connecting rod 22 and the side plate suspension connecting rod 25. Since the width of the sliding cover plate is hung freely, the variation of the width of the sliding cover plate 15 itself due to the central plate 16 and the side plates 19 and 19 and the sliding of the cover plates 12 and 12 and the sliding cover plate 15 can be reduced. The gap G can be covered with the width of the gap by the cover plates 12 and 12 and the sliding cover plate 15 by appropriately selecting the moving range.

[Effect of device]

 As described above, the expansion joint device for a large gap according to the present invention is configured by a plurality of plate materials in which the sliding cover plates adjusted on the back side of the cover plate are laminated so as to be slidable in the width direction, and the suspending means is provided. The expansion joint was able to be installed inside the gap by suspending it so that the front structure does not become wider than the gap width, and therefore the expansion and contraction for the design of the building It has the feature that the unfavorable influence of the joint can be reduced, and the practical effect after implementing the present invention is extremely large.
