Description

Detailed Description of the Invention (Industrial Field of Application) This invention relates to a gap between both roof frames of adjacent buildings, or between a roof frame and a wall frame at a corner such as an inside corner or an outside corner. The invention relates to a corner expansion joint for covering the.

(Prior Art) Conventionally, an expansion joint installed between both roof frames of adjacent buildings or between a roof frame and a wall frame has been disclosed in, for example, Japanese Patent Laid-Open No. 61-36440. There is something. That is, in this case, the holder member is supported by an elastic body between both roof frames of buildings adjacent to each other with a predetermined gap, or between both support members attached to each other between a roof frame and a wall frame. The structure is such that the holder member is slidably installed in a resilient state, and a cover member that covers the gap between the two frame bodies and the roof frame is attached to the holder member. Such a structure has the advantage that the number of component parts of the expansion joint is small, and the structure is simple and can be provided at low cost.

In addition, in the above-mentioned structure, in order to cover the corner gap between both roof frames of adjacent buildings or between the roof frame and the wall frame, the cover member may be extended to the corner, or a separate By connecting the cover member for the corner of the body to the end of the cover member, the gap at the corner is covered.

(Problem to be Solved by the Invention) By the way, it is difficult to solve the problem of expansion joints such as the inside corner and the outside corner of buildings where the outside corner side body and the inside corner side body have a gap and are adjacent to each other in a folded shape. In the corner portion, there are no places on the inner corner side body to which the holder member is attached, and therefore the holder member cannot be installed across both body bodies. As a result, the cover member is not held in place by the movement of the frame, making it difficult to increase the holding force of the cover member at the corner.Furthermore, when wind blows toward the back of the cover member, the wind pressure As a result, problems such as the cover member floating or rattling at the corner portion, and sometimes coming off, occur.

In view of the above-mentioned conventional problems, an object of the present invention is to
An expansion joint for corners that can increase the holding power of the cover member against changes in the structure at corner parts such as inside corners and outside corners, and can prevent the corner parts of the cover member from floating or wobbling. is to provide an in-line.

(Means for Solving the Problem) In order to achieve the above object, the invention of claim 1 provides a corner part for covering a gap at a corner between both roof frames of adjacent buildings or the roof frames. An expansion joint for use in a corner, in which a long support member fixed along the longitudinal direction on the roof frame on the outer corner side of the corner portion is extended to a corner end on the roof frame to provide a corner support. the corner support member is provided so as to be tiltable and slidable in a state in which the corner holder member is resiliently pushed toward the corner support member; A cover member covering the corner gap and the roof frame was combined.

Further, the invention of claim 2 provides a corner gap for covering a corner gap between both roof frames of adjacent buildings or a roof frame and a wall frame, as well as a gap in a straight line portion following the corner gap. The expansion joint is an expansion joint for use in which a pair of elongated supporting members are respectively fixed to both roof skeletons, or a roof skeleton and a wall skeleton, which face each other in the gap between the straight parts, along these two skeletons. A holder member is installed between these long support members so as to be tiltable and slidable in a state in which it is elastically pushed toward the support member, and the holder member has a holder member that is tiltable and slidable. Attach a long cover member to cover the gap and roof frame,
Further, one side edge of the elongated cover member extends to an end of the corner portion to form a corner cover portion, and the elongated cover member is fixed along the roof frame on an outer corner side of the corner portion. A corner support member is formed by extending the support member to a corner end on the same roof frame, and a corner holder member is elastically attached to the corner support member by an elastic body. Provided so that it can be tilted and slid in the raised state,
The corner cover portion was coupled to the corner holder member.

(Function) In the corner expansion joint constructed as described above, when both building frames are displaced relative to each other, the corner holder member slides under the elastic force of the elastic body. The relative displacement can be coped with by moving or tilting.

In addition, the corner holder member provided on the corner support member on the roof frame that forms the outer corner of the corner part,
Since the cover member covering the gap at the corner portion and the roof frame is combined, the holding force of the cover member at the corner portion can be increased.

In particular, since the long support member fixed along the longitudinal direction on the roof frame on the outside corner side of the corner portion is extended to the corner end on the same roof frame to form the corner support member, By fixing the long support member at a predetermined position in the longitudinal direction, the corner support member integrated with the long support member is also fixed, and the corner support member is attached to the corner end of the roof frame. This eliminates the hassle of positioning and fixing. Furthermore, no displacement occurs in the inner and outer directions of the corner support member with respect to the elongated support member.

The other parts are constructed almost the same as in the fourth embodiment. Therefore, this sixth embodiment operates in the same manner as the first embodiment.

(Effects of the Invention) As described above, according to the present invention, when both building frames of a building are relatively displaced, the corner holder member slides or slides while receiving the elastic force of the elastic body. By tilting, it is possible to cope with the relative displacement, so it is possible to prevent an accident in which the cover member or the corner cover portion is twisted or damaged at the corner portion.

Furthermore, since the cover member covering the gap in the corner portion and the roof skeleton is coupled to the corner holder member provided on the corner support member on the roof frame forming the outer corner of the corner portion, the holding force of the cover member at the corner portion is increased. This has the effect that it is possible to actively prevent problems such as the cover member floating or rattling at the corner portion.

In particular, since the long support member fixed along the longitudinal direction on the roof frame on the outside corner side of the corner portion is extended to the corner end on the same roof frame to form the corner support member, By fixing the long support member at a predetermined position in the longitudinal direction, the corner support member integrated with the long support member is also fixed, and the corner support member is attached to the corner end of the roof frame. This eliminates the hassle of positioning and fixing. Furthermore, since there is no misalignment of the corner support member in the inner and outer directions with respect to the long support member,
It is possible to stably and reliably hold the corner holder member and the cover member coupled to the holding member with respect to the corner support member.
