Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in an expansion joint device for covering gaps in walls or ceilings of buildings, particularly in exterior walls.

[Prior Art] Buildings are constantly subject to distortion due to expansion and contraction due to temperature changes, uneven settlement, earthquakes, etc., and gap structures are constructed as a means to prevent buildings from being destroyed due to such distortion.

An example of this type of expansion joint is a building A with a gap G in between, as shown in Figure 3.

It has a structure in which a cover plate 51 is attached to a pair of frame bases 50 and 50 fixed to the ends of A', and both frame bases 50 and 50 are attached to each other.
．． The plate-shaped covering plate 51 is fastened via bolts 53 to a hanging fitting 52 which is telescopically connected between the two ends of the cover plate 51 to cover the surface of the gap G.

[Problems to be Solved by the Invention] However, when the covering plate 51 is made of a metal plate, there is a problem that the covering plate 51 extending along the gap G divides the design of the wall or ceiling of the building. It had Particularly in recent years, as the width of the gap G has increased due to larger and higher-rise buildings, the width of the cover plate 51 has also increased, which has often resulted in an unnatural design.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide an expansion joint device that has a structure that has excellent design consistency with adjacent walls, ceiling surfaces, etc., and has an inconspicuous gap structure.

[Means for Solving the Problems] An expansion joint device according to the present invention has frame bases fixedly installed on each step formed at the edge of both buildings with a gap between the buildings, and A covered connecting plate is slidably installed between the tables, and
``2. A surface substrate is formed on the front edge of both bases, extending from both edges of the covering connecting plate at a gap of approximately the same width as the gap, and slidingly contacting the front surface of the covering connecting plate, The purpose is to continuously construct a decorative structure on the surface of a building on the surface substrate, and the purpose can be further completely achieved by constructing a decorative surface structure similar to the decorative structure on the surface of the building on the surface of the covering connecting plate. It can be made into something.

[Operation] That is, according to the above configuration, by providing the surface decorative structure on the surface substrates facing each other with substantially the same gap as the gap in the building, the width of the structure by the expansion joint device can be expanded. There is no surface decoration structure and level difference (concave level difference).
However, since a decorative surface similar to the surface decorative structure is constructed in the gap, the overall design of the building is not disrupted.

[Example] An example of the expansion joint according to the present invention will be described below with reference to FIGS. 1 and 2.

Reference numerals 1 and 1 indicate the respective steps of buildings a and a with gap G in between;
An angle frame is installed by driving into the outer corner of b, and frame bases 2 and 3 having a substantially U-shaped cross section are fastened to the angle frame 1゜1 through screws 16 to both steps. And they are fixed opposite each other.

One frame base 2 has one mounting plate 46 of the hinge frame 45 fixed to the bottom plate 21 near the edge of the gap G, and a front substrate 23 whose end faces the end position of the gap G. is fastened to the front edge of the side plate portion 22 via screws 1-7. The other frame base 3 has the hinge frame 4 attached to the inner edge of the bottom plate portion 3''.
The inner plate part 32 is constructed such that the end edge thereof is approximately at the same level as the level of the mounting part 47 of No. The auxiliary surface substrate 36 whose end faces the end position of the gap G is fastened via the screw 18.

Reference numeral 4 denotes a covering connecting plate 4 that is stretched between the frame bases 2 and 3, and a surface decorative material C, which will be described later, is attached to the front surface between both edges 41 and 41 via an appropriate adhesive 42. Same or similar
It is made by pasting a surface decorative material 43 such as tiles. The covered connecting plate 4 has a rear surface closer to one side fixedly connected to a mounting portion 47 of a hinge frame 45, and is slidably supported by a pivot portion 48 of the hinge frame 45, and a rear surface closer to the other side is fixedly connected to a mounting portion 47 of a hinge frame 45. The packings 1.5.15 are slidably supported on the edge of the inner plate part 32, and are also slidably and closely attached to the front surface of the surface decorative material 43, respectively fixed to the edges of the surface substrate 23 and the auxiliary surface substrate 36. Each of the packings 15.15 has a base portion fitted and fixed into a fitting groove 24.37 formed on the back side of the edge of the front substrate 23 and the auxiliary front substrate 36.

The front surface a1 of the building a, each surface of the front substrate 23.35 and the auxiliary surface substrate 36 are finished to the same level,
A decorative surface material C such as a tile is applied to the front surface a1 of one building a and the surface substrate 23 via the subsurface structure C1.
At the same time, a subsurface structure C is provided on the front surface a1 of the other building a, the surface substrate portion 35, and the auxiliary surface substrate 36.
A decorative surface material C such as a tile is applied to the auxiliary surface substrate 3 through 1.
It is covered up to the edge of 6.

Incidentally, if necessary, a water return gutter 12 made of flexible synthetic resin may be interposed between the two angle frames -21.

The expansion joint with the above configuration is provided at each step of buildings a, a,
Angle frames 1, 1 are driven and installed at the outer corners of b, respectively, and frame bases 2, 3 are fastened and fixed to each angle frame 1, 1 with screws 16, and are opposed to each other with a gap G in between.

For each frame base 2, screws 17 and 18 are removed and the front board 23 and auxiliary front board 36 are removed.In this state, both frame bases 2,
The covering connecting plate 4 is suspended between the two edges 41, 4.
A surface decorative material 43 is attached to the front surface between 1 and 1 through an appropriate adhesive 42.
Paste.

After that, screws 1.7.18 are fastened to fix the front substrate 23 and the auxiliary surface substrate 36, forming each surface of the front substrate 23.35 and the auxiliary surface substrate 36 at the same level as the front surface a1 of the building a. . The front surface a1 of the building a and the surface substrate 23.35
The construction is completed by covering each surface of the auxiliary surface substrate 36 with a surface decorative material C such as a tile via the surface structure c1, and it is possible to obtain a surface structure of a building in which the joint structure is inconspicuous.

[Effects of the Invention] As described above, the expansion joint according to the present invention has a structure in which the surface decorative structure is provided on the surface substrates facing each other with substantially the same gap as the gap between the buildings, so that the expansion joint can expand and contract. The width of the part structure is not expanded by the joint device, and the line of the expansion joint part is not emphasized and the overall design of the building is not divided.

In addition, although there is a level difference between the surface and the surface decorative structure, a decorative surface similar to the surface decorative structure is constructed in the gap, so the design of the entire building is continuous and does not feel strange. Therefore, the effects after implementing the present invention are extremely large.
