Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a means for covering a gap structure constructed in a building,
In particular, the present invention relates to improvement of an interior expansion joint device for covering a ceiling surface, an inner wall surface, and a gap between a ceiling surface and an inner wall surface of a building.

[Prior Art] Buildings are constantly subject to distortion due to expansion and contraction due to temperature changes, uneven settlement, earthquakes, etc., and when building a structure, a gap structure is constructed as a means to prevent the structure from being destroyed due to such distortion. There is. Therefore, when finishing the interior of such a building, it is necessary to cover this interstitial structure while maintaining elasticity.

As shown in Fig. 3, this type of expansion joint includes a pair of edge frames 5 fixed to the ends of a building a and a with a gap G in between.
It has a structure in which a cover plate 51 is attached to the edge frames 50 and 50, and supports the edges of the ceiling plates A and B stretched from both sides to the edge frames 50 and 50 in an engaged state. Frame 50,5
The covering plate 51, which is a flat plate and has a sufficient width W to accommodate the distortion of the gap G, is attached to the hanging metal fitting 52, which is telescopically inserted and carried between the gaps 50 and 50, through bolts 53. It is fastened to cover the surface of the gap G.

[Problems to be Solved by the Invention] However, according to the structure of the covering plate 51, the width W thereof becomes considerably larger than the gap G due to the structure.
There was a problem in that the covering plate 51 extending along the gap G divided the design of the ceiling surface or inner wall surface of the building. Particularly in recent years, as the width of the gap G has increased as buildings have become larger and taller, the width W 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 interior expansion joint device in which the sparse structure of adjacent inner walls, ceiling surfaces, etc. is not so noticeable from the surface. .

[Means for Solving the Problems] The interior expansion joint device according to the present invention includes an edge base frame fixedly installed at the edge of both buildings across a gap between the buildings, and a front side of the edge base frame. an edge frame assembly that forms a subdued internal vaginal part having a slit gap on the edge side of the structure when both members are fastened by an edge frame member that can be fixed to the structure via a fastening member such as a screw; The gist is that it is composed of a flat cover connecting plate whose both side edges are slidably inserted and supported in the inner cavity through the slit gap of the opposing edge frame assemblies.

In addition, in the case of a gap between a ceiling surface and an inner wall surface, or between an inner wall surface and an inner wall surface, one side of the covering connecting plate can be pivoted to a wall mounting bracket via a hinge mechanism so that it can be angularly displaced in a direction perpendicular to the surface. It can be realized.

Furthermore, it is preferable that the inner wall material engagement edge is integrally formed with the inner edge of the edge frame material.

[Operation] That is, according to the above configuration, the covering connecting plate inserts the edge into the inner cavity of the cover through the slit gap of the edge frame assembly constituted by the edge base frame and the edge frame material. By fixing the edge of the edge frame assembly so as to substantially coincide with the edge of the building, the cover connecting plate appearing between the edge frame assemblies can be made as wide as the gap in the building.

[Example] An example of an interior expansion joint according to the present invention will be described below with reference to the drawings.

FIG. 1 shows an expansion joint that covers a gap between ceiling surfaces or between inner wall surfaces, and the ceiling surface will be explained.

Reference numerals 1 and 1 denote edge base frames which are fastened to structural members c and c along the inner edges of the edges thereof through 3° screws and fixed oppositely to the structures a and a with a gap G between them. The cross section of the edge base frame has a front edge 4 on one side of the bottom plate 2 in which a small hole 3 for the insertion of a screw 3o is bored.
It comprises a folded edge 5 having a fitting groove 4 on one side on the opposite side. Reference numeral 6 denotes an edge frame material having approximately the same width as the edge base frame 1, and a front edge 81 formed on one side of the mounting plate portion 7 to face the front edge 4 on the opposite side. is the above (+
Along with forming a bent edge 9 that fits into the M fitting groove 4.

It is fastened and integrated with the folded edge 5 via screws 31 to form an edge frame assembly 10 consisting of the edge base frame 1 and the edge frame material 6. When assembling both parts, the edge frame assembly 10 is assembled with the front edges 4 of both parts.
A slit gap 12 is formed between the holes 8 and 8, which communicates with the inner cavity 11 of the cover. Furthermore, an inner wall material engaging edge 13 having a substantially U-shaped cross section is formed on the inner edge of the edge frame material 6 on the front edge 8 side. Reference numeral 14 denotes a covered connecting plate having a width W sufficiently wider than the gap G of the building, and bent edges 15, 15 are formed on both edges of the plate, and both edges are connected to the edge frame assembly 10, respectively. The slit gap 12 has a gap width that allows the thickness of the covering connecting plate 14 to slide.

When constructing an interior expansion joint having the above configuration, the edge of the structural member a, a provided along the inner edge of the building a, which faces each other through the gap G, is connected to the structural member a, a through the screw 30. Frame 1
, 1 is concluded. Next, the cover connecting plate 14 is positioned so as to straddle the front edges 4, 4 of the both edge base frames 1, 1, and the edge frame members 6.6 are fastened and fixed to the both edge base frames 1, 1 by screws 31, respectively.

By this fastening, the covering connecting plate 14 is closed to the slit gap 12 formed between the front edges 4 and 8 of the both edge frame assemblies 10.
．． 12, and the inner wall materials such as ceiling boards (s, b) are finished with their edges engaged with the inner wall material engaging edge 13 formed on the inner edge of the front edge 8 side of the edge frame material 6. Perform construction.

Next, FIG. 2 shows an expansion joint between a ceiling surface and a wall surface, or a wall surface and a surface intersecting the wall surface.

To explain the structure different from the first embodiment, reference numeral 16 is a corner cover connecting plate, which has a bent edge 17 on one side and a C-shaped cross-section hinge extending in the longitudinal direction on the other edge. A hinge mechanism 22 is formed by forming a groove 18 and pivotally pivoting a longitudinally extending shaft-like engagement edge 21 formed at the edge of the bending groove 20 of the wall mounting bracket 19 to the hinge groove 18. It consists of

In the above configuration, the corner cover connecting plate 16 is assembled on the bent edge 17 side to the edge frame assembly 10 in the same manner as in the above embodiment, and on the hinge mechanism 22 side, the wall mounting bracket 19 is fixed to the wall structure 4 with the screw 32. The construction will be completed by doing this.

[Effects of the Invention] As described above, the expansion joint according to the present invention can suppress the exposure of the covering connecting plate to approximately the same width as the gap in the structure, so that the width of the structure can be reduced by the expansion joint device. It will not be enlarged, and the line of the expansion joint will not be emphasized and disrupt the overall design of the building. Therefore, it has the feature of being able to reduce the design discomfort on the inner wall surface of a building, and the effects after implementation of the present invention are extremely large.
