Such a backup material is inserted from the end on the other end side of the frame material which is not joined, and is moved to the vicinity of the joint and arranged.

  The backup material as described above is inserted from the small end of the frame material which is not joined and moved to the vicinity of the joint so that it is difficult to arrange the backup material in an appropriate position, and for example, it is recessed There is a problem that it takes longer to attach than a member that fits into the fitting portion.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a backup material which can be easily disposed in a short time, and a fixture provided with the backup material. is there.

  In order to achieve the above object, according to the backup material of the present invention, end portions of a plurality of frame members having a face material accommodating portion for accommodating the peripheral end portion of the face material and an adjacent space adjacent to the surface material accommodating portion An elastically deformable backup material for restricting the flow of a sealing material filled in the adjacent space, of a joint portion which is butted and joined, a main body disposed in the adjacent space, and the face material It is a back-up material characterized by having a holding part which connects a storing part and the adjacent space, and which is held by a communicating opening whose width in the in-plane direction of the surface material is narrower than the adjacent space.

  According to such a backup material, the elastically deformable backup material is compressed and inserted from the communication opening in which the width of the in-plane direction of the surface material is smaller than that in the adjacent space. It is possible to restore and arrange the main body in the adjacent space. Further, it is possible to easily attach the backup material in a state in which the main body portion is disposed in the adjacent space only by inserting the elastically deformable backup material while compressing it from the communication opening. Therefore, it is possible to provide a backup material that can be easily arranged in a short time.

In the backup material, it is preferable that the main body portion has a slit along a direction intersecting a direction in which the facing material accommodation portion and the adjacent space communicate with each other.
According to such a backup material, since the slit is provided in the main body section in the direction intersecting the direction in which the face material accommodation section and the adjacent space communicate with each other, the main body section is simply inserted into the communication opening. It is possible to make deformation larger than in the case of compression. For this reason, it is possible to compress and thin the main body portion, release from compression, and restore more largely in the adjacent space, thereby narrowing the penetrating space in the longitudinal direction of the frame material.

It is desirable that the main body portion be in contact with the inner wall forming the adjacent space of the frame material.
