Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to the improvement of expansion joints that cover spaces between buildings, and an end cover for expansion joints that is particularly suitable for expansion joints that have a large strain absorption width. It is related to.

[Conventional technology]

Buildings are constantly subject to distortion due to expansion and contraction due to temperature changes, uneven settlement, earthquakes, etc., and in order to prevent damage to buildings due to such distortion, large buildings are constructed with interlayer structures. However, in the past, various expansion joints have been used to cover this gap.

Therefore, at the corner where the floor expansion joint and the wall expansion joint meet, an end cover that extends from the end of the wall expansion joint conventionally moves in and out in response to the tilting of the floor expansion joint. It has a structure that covers the corner clearance.

[Problem that the invention seeks to solve]

However, as buildings have become larger in recent years, the width of the gap has widened, and the amount of retraction of the end cover when tilting has increased, resulting in the problem of a large wedge-shaped gap between the end cover and the floor expansion joint. It had

The present invention has been made in view of the above-mentioned problems, and in particular, in an expansion joint that covers a large space, the end cover extending from the end of the wall expansion joint comes out in response to the inclination of the floor expansion joint. The object of the present invention is to provide an end cover for an expansion joint that has a small gap when retracting.

[Means for solving problems]

The end cover for an expansion joint according to the present invention has an appropriate length and is fixedly attached to the edges of both buildings with a gap between them in a wall expansion joint installed in a strain absorbing space of a building. a pair of fixed end plates, a pair of sliding plates supported horizontally in parallel so as to be slidable laterally relative to each of the fixed end plates; a sliding cover that covers the plates so that they can be slid independently in the longitudinal direction; and a sliding cover that covers both sides of the sliding cover so that it can slide from the front side, and that is fixed to each of the fixed end plates. The main feature is that the fixed cover is constructed at the end of the expansion joint so that the end comes into contact with the adjacent expansion joint.

[Effect]

Therefore, the end cover for an expansion joint having the above configuration includes a pair of sliding plates and a sliding cover that covers the sliding plates between the fixed end plates that are fixed across the building.
Since the structure covers the corner of the gap, if the contact surface of the adjacent expansion joint is inclined, the sliding cover and both sliding plates will retreat with one end in contact with the surface of the adjacent expansion joint. do. At this time, the sliding plate that slides on the inner surface of the sliding cover has half the width of the sliding cover, so the amount of retraction is also half that of the sliding cover, making it possible to reduce the wedge-shaped gap caused by displacement. can.

〔Example〕

Embodiments of the expansion joint according to the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show an embodiment of an end cover for a floor expansion joint, and reference numerals 1 and 1 are fixed end plates made of stainless steel plates processed into sheet metal,
They are fixed by fastening members such as bolts 3 to block members 2, 2 fixedly fixed at each end of buildings a, a' facing each other with a gap in between. Both fixed end plates 1 have short channel-like end surfaces, and have two notches 5, 5 on the inner edge 4 side.
A wider outer edge 6 is formed. Symbols 7, 7 are sliding plates shorter than the fixed end plate 1, and guide ribs 8, 8 extend laterally on the back side and engage with the notch 5 so as to be slidable in the lateral direction (arrow A).
It is made by protruding. Further, the pair of sliding plates 7, 7 are arranged in parallel in the lateral direction between the side edges 10, 10 formed on both sides of the front surfaces of the sliding plates 7, 7, and each independently in the longitudinal direction (arrow B) is provided with a sliding cover 9 which is slidably carried by the fixed covers 11, 11, which are fastened and fixed to the fixed plates 1, 1 by means of small screws 12, respectively. Therefore, both ends of the front surface are held down, and the sliding cover 9 has sufficient clearance to slide vertically and horizontally relative to the fixed covers 11, 11.

In the figure, reference numeral 13 denotes a gutter-shaped water stop plate made of a soft material such as vinyl chloride resin and fixed between the block members 2, which are arranged in parallel.

The end cover for an expansion joint having the above configuration includes a pair of sliding plates 7, 7 installed between the fixed end plates 1, 1 fixedly fixed between the buildings a and a', and the sliding plates 7, 7, 7
Since the structure is such that the sliding cover 9 covers the corner of the gap, when the contact surfaces of the adjacent expansion joints 50 are inclined, the sliding cover 9 will cover one end as shown in FIG. It retreats while in contact with the surface of the expansion joint 50. At this time, the sliding plates 7, 7 sliding on the inner surface of the expansion joint 50 each move back with one end in contact with the surface of the expansion joint 50, but each sliding plate 7, 7 slides on the inner surface of the expansion joint 50. Since the cover 9 is half width,
The amount of retraction is also half that of the sliding cover, making it possible to reduce the wedge-shaped gap caused by displacement.

Next, FIG. 5 shows an embodiment of an end cover for an expansion joint for a wall or a ceiling, and a description will be given of portions in which the shapes of the components differ from those of the end cover for an expansion joint for a floor.

This embodiment is molded from aluminum frame material, and the fixed end plates 1, 1 are provided with fixed cover fitting protrusions 14 extending in the longitudinal direction on the front surfaces of both sides, and both fixed covers 11 are provided. , 11 so as to be fitted and fixed to a fitting groove 15 extending in the longitudinal direction formed on the outer side of the back surface of each of the fitting grooves 11. In addition, a packing groove 16 extending in the longitudinal direction formed on the inner side of the back surface of both fixed covers 11 is fitted with a packing 17 that slides into contact with the front surface of the sliding cover 9.

〔Effect of the invention〕

As described above, the end cover for an expansion joint according to the present invention can be slid in the longitudinal direction of the sliding cover that is installed to be slidable in the longitudinal and lateral directions between buildings. By arranging a pair of sliding plates that can move freely in parallel, it is possible to reduce the amount of retreat of the sliding plates when the contact surfaces of adjacent expansion joints are inclined. The practical effects after implementing the invention are extremely large.
