CONSTITUTION:Hanging members 16 and 26 are respectively fixed to the rear of the internal ends of fixed bearing plates 11 and 21 of coupling plate brackets 1 and 2. A coupling plate mounting arm 3 is pivoted freely inclinably on the center of a coupling arm 31 constructed between the hanging members 16 and 26 through a small screw 32. In addition, a coupling plate 4 fixed to the coupling plate mounting arm 3 through a small screw 33 is spaned to bearing edges 12 and 22 of the coupling plate bearing brackets 1 and 2. After that, mounting higes 7 and 8 connecting to a wall (a) are swingably pivoted on the external ends of the fixed bearing plates 11 and 21. In the constitution, the load on mounting elements caused by expansion and strain can be prevented.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to improvements in expansion joints that cover gaps in buildings, and particularly relates to the structure of mounting hinges in expansion joints used in gaps in large spans. be.

[Prior Art] Buildings are subject to distortion due to constant expansion and contraction due to temperature changes, uneven settlement, earthquakes, etc., so gap structures are constructed as a means to prevent buildings from being destroyed due to such distortion. Expansion joints are used as a covering structure, but as buildings become larger, the span of the gap becomes larger and longer, so expansion and contraction and distortion of the expansion joint itself due to temperature changes has become a problem.

[Problem to be solved by the invention] The present invention has been made in view of the above problems.

The object of the present invention is to provide a new mounting hinge structure for an expansion joint that can be fixedly installed between walls by simple construction, especially for covering a large-span strain-absorbing gap. It is.

[Means for Solving the Problems] That is, the structure of the mounting hinge in the expansion joint according to the present invention is such that the structure of the mounting hinge in the expansion joint according to the present invention is
Continuing from the outer edge of the support fixed plate portion having a suitable width and having a support edge at the inner end, a front plate parallel to the front side of the support fixed plate portion is formed, and on the back surface of the inner end side of the support fixed plate portion. a pair of connecting plate support brackets each having a U-shaped cross-section hanging member; and a connecting plate pivotably tilted to a connecting arm suspended between the hanging members of the reconnecting plate support bracket. a connecting plate fixed to the front surface of the mounting arm and suspended from the support edge of the reconnecting plate support bracket; and a connecting plate fixed to the front surface of the front plate of the reconnecting plate support bracket, both edges of the connecting plate. and a cover plate which is slidably held between the inner edge and the supporting edge of the connecting plate support bracket, respectively, and the outer end of the reconnecting plate supporting bracket is attached to the outer wall surface with a gap therebetween. The main feature is that the support structure is pivotally connected via a mounting hinge that is rotatable in a direction inclined to the mounting surface, and that the support structures are arranged at equal intervals in the longitudinal direction of the expansion joint.

[Function] According to the above configuration, the cover plate and the connecting plate of the expansion joint are suspended and supported by the connecting plate support bracket fixed to the wall surface by means of the mounting hinge. Therefore, by cutting the connecting plate and the cover plate to appropriate lengths, expansion/contraction and distortion due to temperature changes of the expansion joint itself are separated, and no load is applied to the attachment site. As a result, it can be implemented as an expansion joint that covers a long strain absorbing gap with a large span.

The outer end of the support plate 21 constitutes a mounting hinge 8 that connects to the wall a, and has a hinge protrusion 81 protruding from the outer end surface, and a hinge protrusion 83 protruding from the base plate 82. are pivotally connected via a pin shaft 84 between them, and
The base plate 82 is fastened and fixed by bolts 86.86 screwed into anchor plugs 85.85 embedded in the bottom surface of the stepped portion a1.

Support fixed plate portion 11 of the above-mentioned both connecting plate support brackets 1 and 2,
On the back surface of the inner end side of each of the hook members 16 and 21, a U-shaped cross section hooking member 16 and 26 is fixed.
6.26 A connecting plate mounting arm 3 which is screwed and fastened through a small screw 32 is pivotally attached to the center of the connecting arm 31 suspended between 6 and 26. A connecting plate 4, which is fixed via screws 33 and 33, is suspended from the supporting edges 12 and 22 of both the connecting plate support brackets 1 and 2.

Further, the connecting plate 4 is connected to both the connecting plate supporting brackets 1 and 2.
