Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an expansion joint for covering a gap between skeletons appearing on a surface of a building, and more particularly to an expansion joint having a drainage structure.

[0002]

[Prior Art]

 Conventionally, a gap is formed between the frames as a structure that absorbs expansion and contraction due to temperature changes, uneven settlement, and strain due to earthquakes, etc., and prevents the destruction of buildings caused by such strain. Therefore, this gap appears between the floor surface and the wall surface of the building, so when using it, expansion joints of various structures are used as a structure that covers the gap so that it can expand and contract and absorb level differences. ing.

Also, when two skeletons having a different basic structure from an adjacent skeleton such as a parking lot are connected, a gap is formed between the two skeletons due to the difference in their properties, and this is used as an expansion joint. Therefore, coating is a conventional means.

[0004]

[Problems to be solved by the device]

 However, since the coating of these gaps differs depending on the conditions such as the structure and size of both the skeletons, despite the development of various structures, the next preferred structure is required. It is a thing.

An object of the present invention is to provide an expansion joint that is simple in structure and is particularly suitable for covering a building having a structure that actively drains water that has entered from the covering surface. .

[0006]

[Means for Solving the Problems]

 That is, in the expansion joint according to the present invention, in the expansion joint to be installed in the gap structure constituted by the strain absorbing gap formed between the structures of the structure, the expansion joints are fixed to the opposite edges of both the structures opposite to each other with the gap interposed therebetween. Between the support base frame, which is provided with a groove-shaped support base frame having water draining holes at the opposite corners, and the front wall that is fixed to the groove structure rear wall of the support base frame. A holding frame having a slit-shaped gap extending in the longitudinal direction and a support frame formed by the supporting base frame and the holding frame sandwiching both end edges slidably in the surface direction with respect to the slit-shaped gap of the supporting member. And a pair of spring members that are elastically mounted between the both end edges of the above-mentioned cover plate and the supporting base frame in which the end edges are inserted to hold the cover plate neutrally. Is the gist.

[0007]

[Action]

 The expansion joint having the above-mentioned structure is provided with drainage holes at the opposite corners of the supporting base frame, which has a groove-shaped supporting member fixed to the end faces of both frames with a gap. By making the holes, water that has entered the expansion joint can be positively dropped through the water drain holes in the gap direction of the skeleton, and a flexible waterproof gutter is installed between the skeletons. Therefore, the invading water can be controlled.

[0008]

【Example】

 An embodiment of the expansion joint according to the present invention will be described below with reference to the drawings. Reference numerals 1 and 1 denote support members made of an aluminum-shaped material that are fixedly fixed to each other at the same level in both the frames a and a with a gap G interposed therebetween. The cover plate 2 slides in the width direction between the support members 1 and 1. It was freely installed horizontally.

The support base frame 3 of both the support members 1 and 1 has a bottom plate portion 31 fixed to the end surface of each of the skeletons a and a via mounting bolts 90. The supporting base frame 3 has a flat groove shape continuous in the gap direction, and a front wall 33 whose height is lower than that of the rear wall 32 by the plate thickness of the covering plate 2 is formed on the front side of the bottom plate portion 31, and the pressing is performed. The frame mounting plate portion 34 extends from the rear wall 32 in parallel with the bottom plate portion 31. A large number of drainage holes 35, 35 ... Are provided at appropriate intervals in the longitudinal direction at the corners of the bottom plate portion 31 and the front wall 33.

The pressing frame mounting plate portion 34 of the supporting base frame 3 is formed by fixing the pressing frame plate 4 with a small screw 91. The supporting frame plate 4 is fixed to the front edge of the pressing frame plate 4 at the time of fixing. A slit-like gap G1 is formed between the front wall 33 of the frame 3 and the cover plate 2 described later so as to be slidably sandwiched by the plate thickness of the cover plate 2.

The cover plate 2 has a large number of through holes 21, 21 ... Arranged and drilled on the plate surface, and locking edges 5, 5 having L-shaped cross-sections at both end edges of the cover plate 2, respectively. Are fixed to each other, and the end edges of the support members 1 and 1 are slidably held in the surface direction with respect to a slit-shaped gap G1 formed by the support base frame 3 and the holding frame 4.

Further, reference numeral 6 is a plane-shaped “V” -shaped plate spring elastically mounted between the locking edge 5 and the rear edge 32 of the supporting base frame 3 in the inner cavities of the supporting members 1 and 1, respectively. It is fixed to the rear edge 32 by means of the small screw 51, and is arranged in the longitudinal direction at appropriate intervals.

Reference numeral 7 in the drawing is a flexible structure in which both edges are sandwiched and fixed between both the frames a, a and the support base frame 3 bottom plate portion 31 of the support members 1, 1 and are loosely installed between the gaps G. A waterproof gutter made of water-soluble synthetic resin. Surface materials s, s are provided on the surfaces of the frames a, a, and a caulking material 8 is filled between the surface material s and the support member 1.

In the expansion joint having the above-described structure, the expansion / contraction displacement of the gap width G between the skeletons a and The cover plate 2 has a structure in which it slides in the surface direction and absorbs it, and the cover plate 2 is always elastically held in a stable position by the plate springs 6 and 6 provided on both sides thereof. Then, rainwater and the like that have entered the inner cavities of the support base frame 3 and the holding frame plate 4 of the expansion joint flow along the grooves of the support base frame 3 and from the water drain holes 35, 35 ... It falls into the gap G. Therefore, the water that has entered the gap G from the through holes 21, 21 ... Of the covering plate 2 flows out to the predetermined drainage portion through the water shutoff gutter 7.

[0015]

[Effect of the device]

 As described above, the expansion joint according to the present invention has a water-permeable hole at the opposite side corner of the groove-shaped cross section with respect to the support base frame that constitutes the support member fixed to the end faces of the two bodies with a gap. Since it has a feature that the water that enters the expansion joint can be actively discharged and managed, the practical effect after implementing the present invention is extremely large.
