Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is designed to reduce the gap between both roof frames of adjacent buildings, or at a corner such as a large corner or a protruding corner between a roof frame and a wall frame. This relates to a corner expansion joint for covering.

(Prior Art) Conventionally, an extension joint installed between both roof frames of adjacent buildings or between a roof frame and a wall frame has been disclosed, for example, in Japanese Patent Application Laid-Open No. 61-36550. There is. That is, in this case, both roof frames of adjacent buildings separated by a predetermined gap,
Alternatively, a holder member is slidably installed between the supporting members of the roof frame and the wall frame that are attached to each other by an elastic body, and the holder member There is 1 cover member that covers the gap between the frames and the roof frame! It is designed to be worn. 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 case, in order to cover the corner gap between both roof frames of adjacent buildings or between the roof frame and wall frame, the cover member may be extended to the corner, or a separate cover member may be extended to the corner. 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, in the corner part of an expansion joint such as the large corner or projecting corner of a building that is adjacent to each other, there is a gap between the outer corner side frame and the inner corner side frame. , there are no places on the inner corner side frame to which the holder member can be attached, so it is not possible to erect the holder member across the space between the two frame bodies. Therefore, the cover member is not held due to the movement of the frame,
This makes 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 causes the cover member to
Problems such as floating, rattling, and sometimes coming off may occur in the parts where the parts are attached.

In view of the above-mentioned conventional problems, it is an object of the present invention to increase the holding power of a cover member against fluctuations in the frame at corner portions such as large corners and protruding corners, and to prevent lifting or rattling of the corner portions of the cover member. To provide a corner expansion join that can prevent sticking.

(Means for Solving the Problems) In order to achieve the above object, the invention of claim 1 provides a method for covering the gap at the corner between both roof frames of adjacent buildings or between a roof frame and a wall frame. This is a corner expansion joint, in which a support member is disposed on the roof frame on the outer corner side of the corner part, and the support member has a corner holder member that is elastically springed by an elastic body so that the corner holder member can be tilted and rotated.
NvJ is possible, and the corner holder member is combined with a cover member that covers the corner gap and the roof frame.

Furthermore, 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. A support member is provided between the two roof structures or the roof structure and the wall structure that face each other in the gap between the linear parts, and a holder member is provided between the support members. is installed so as to be tiltable and slidable in a state where it is resiliently pushed against the support member by an elastic body, and a cover member is attached to the holder member to cover the gap between the two frame bodies and the roof frame, and further, One side edge is extended to the corner part to form a corner cover part, while a support member on the roof frame on the outer corner side of the corner part is provided with a corner holder member that is resiliently held by an elastic body and can be tilted and slid. The corner cover portion is movably provided, and the corner cover portion is 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. Alternatively, by tilting, it is possible to cope with the relative displacement, so at the corner part,
Accidents in which the cover member or the corner cover portion is twisted or damaged can be prevented.

In particular, since the cover member that covers the gap in the corner portion and the roof skeleton is coupled to the corner holder member provided on the support member on the roof skeleton that forms the outer corner of the corner portion, the holding force of the cover member at the corner portion is reduced. This makes it possible to prevent problems such as the cover member floating up or rattling at the corner portions.
