Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an expansion joint for absorbing strain in a building, and more particularly to an expansion joint for an inner wall formed on a wall portion of glass or a board.

[0002]

[Prior art]

 Since structures are constantly distorted due to expansion and contraction due to temperature changes, unequal subsidence, and earthquakes, etc., a gap structure is constructed in the skeleton as a means to prevent destruction of buildings from such distortion. Therefore, since a gap appears on the wall surface of the building, an expansion joint is used as a structure that covers the gap so that it can be expanded and narrowed and can absorb the level difference. Expansion joints of various constructions are used.

[0003]

[Problems to be solved by the device]

 However, since this gap structure must be constructed the same inside the building, the expansion joint used for the inner wall is not only the concrete wall but also the decorative material that covers the surface of the concrete wall. Expansion joints must also be used at positions corresponding to the gaps of various surface materials such as various boards, and especially in the case of glass plates, the expansion structure may become a problem in order to eliminate damage due to distortion. Many. Further, the expansion joint has a drawback that the design of the inner wall surface is impaired.

The present invention has been made in view of the above problems, and can be smartly used for an inner wall surface of a structure formed of a board material such as glass, and has a simple structure. It is an object of the present invention to provide a beautiful expansion joint for an inner wall that does not damage the design of the inner wall.

[0005]

[Means for Solving the Problems]

 The expansion joint for an inner wall according to the present invention is an expansion joint in which a board-shaped inner wall such as a glass plate crosses a strain absorbing gap of a building, and an outer groove portion formed in a base portion is appropriately elastically sealed. And a base frame formed by fitting an engaging projection having a hinge end extending in the longitudinal direction at the groove center of the inner groove portion while being fitted to the opposite edges of the board-shaped inner wall via the hinge. A hinge structure in which a hinge engaging end that rotatably fits with the end is provided, and when the hinge engaging end and the hinge end are fitted and pivoted to each other, there is a slight swingable angle with respect to the base frame. In addition to the above, the two cover plates are spaced apart from the base and formed in parallel so as to project in a direction to cover the strain absorbing gap, and sliding lips are provided along the longitudinal direction at the edge of each cover plate. The inner edge of the board-shaped inner wall that opposes the above-mentioned pair of members. On the other hand, the gist is that the outer groove portions of the base frame are fitted and fixed to each other, and the respective sliding lips are configured to slide in close contact with each other on the surface of the covering plate extending from the sliding frames facing each other. It is a thing.

Further, it is preferable that each of the base frame and the sliding frame is formed of an aluminum form material.

[0007]

[Action]

 According to the above configuration, the strain in the plane direction of the board-shaped inner wall that traverses the strain absorbing gap can be absorbed by the change in the overlapping amount of the cover plate of the sliding frame extending from both directions, and The tilt is absorbed by the angular displacement of both hinge structures.

[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 are base frames formed by aluminum form members and fixed to opposite ends of the glass plates a and a, respectively. The base frame 1 has a substantially H-shaped cross section. Then, the edge of the glass plate a is fitted into the outer groove portion 2 through the gasket 3 made of an elastic material, and the gap between the outer groove portion 2 and the glass plate a is filled with the elastic sealing material 4 and fixed. become. An engaging projection 7 having a cylindrical hinge end 8 extending in the longitudinal direction is provided at the center of the inner groove 5 of the base frame 1.

Further, reference numerals 9 and 9 are sliding frames which are formed of an aluminum frame material similarly to the base frame 1 and are pivotally integrated with the inner groove portion 5 of the base frame 1, respectively, and have a substantially cross section. At the center of the T-shaped base 10, there is provided a hinge engaging end 11 having a C-shaped cross section and extending in the longitudinal direction, which is rotatably fitted to the cylindrical hinge end 8. Then, when the cylindrical hinge end 8 is fitted and pivoted to the hinge engaging end 11, minute gaps (12) are formed at both ends of the base 10 and the end of the inner groove 5, respectively. The sliding frame 9 is tilted with respect to the base frame 1 to form a hinge structure 13.

Two covering plates 14 and 14 extend in the surface direction from the above-mentioned base 10 at its end and about 2/3 position, and are formed in such a manner as to cover the strain absorbing gap G. A sliding lip 16 made of elastic rubber is fitted and integrated in a packing fitting groove 15 formed continuously on the edge of the covering plate 14 in the longitudinal direction so as to project from the surface of the covering plate 14. The sliding lips 16 are in close contact with the surface of the covering plate 14 extending from the sliding frame 6 fixed to the opposing glass plate a.

The expansion joint for the inner wall having the above-described structure is used for an inner wall structure in which a glass plate material crosses the strain absorbing gap G portion, and extends the strain in the plane direction (arrow A) from both directions. It is absorbed by the variation of the overlapping amount of the covering plates 14, 14 of the sliding frame 9, and the inclination of the surface is absorbed by the angular displacement of both hinge structures 13, 13.

It should be noted that the expansion joint for inner wall can be used not only as a glass plate but also as a strain absorbing structure for a portion where inner wall materials such as various board materials cross the strain absorbing gap G. Needless to say.

[0013]

[Effect of device]

 As described above, the expansion joint for the inner wall according to the present invention has the inner wall strain absorbing structure formed of the glass plate or the like traversing the strain absorbing gap, which is formed of the aluminum form material, Since it has a smart structure that is fitted to the edge of the inner wall plate, it has the characteristic that the design of the inner wall surface can be maintained and it can be kept beautiful. Extremely large.
