There was one. Further, as a device used when sound insulation performance is required, there has been a device in which a pair of projecting pieces are formed in the longitudinal direction at the center of the back surface of the backing plate body, and a holding portion to which a refractory material can be attached is provided. We use seismic slit materials and fireproof materials attached to these backing plates, but the method of attachment is to use seismic slitting materials with adhesive tape pasted on one side in advance, on both sides of the flat surface of the backing plate, In the meantime, the adhesive tape was stuck so as to form a gap with a certain width, a refractory material was fitted into the gap, and an adhesive tape was stuck from the surface so as not to get out. Also, when sound insulation performance is required, the seismic slit material is similarly attached to the surface of the backing plate body, then the refractory material is fitted into the holding part formed on the back surface, so that it does not fall out. It was stuck from the surface with adhesive tape.

[0003]

In the above conventional method,
Preparing to attach the adhesive tape to the anti-seismic slit material is required in advance to attach and attach the backing plate and the anti-seismic slit material or fire-resistant material with adhesive tape, and to apply by hand In addition, the mounting accuracy is poor, and the use of a large amount of adhesive tape is not economical.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to use an earthquake-resistant slit material or a fire-resistant material without using an adhesive tape or the like.
An object of the present invention is to provide a backing plate that can be easily and accurately attached and that can securely hold them.

[0005] As means for this, a pair of left and right holding pieces having at least one or more inwardly formed protrusions are formed along the longitudinal direction substantially at the center of the surface of the plate-shaped backing plate body, and the refractory material is attached. At the same time as the mounting part, on both sides of the surface of the backing plate main body, a protruding piece that inserts and holds the seismic slit material, and on the back side, a support arm that hooks to the separator that holds the formwork is slidable up and down Are formed along the longitudinal direction, respectively. In addition, the mounting portion is provided at a position substantially at the center of the back surface of the backing plate main body, or is provided at a position substantially at the center of both surfaces of the backing plate main body.

According to the above structure, a pair of left and right holding pieces are formed along the longitudinal direction on the front surface, the back surface, and substantially the center of both surfaces of the backing plate body to provide a mounting portion for attaching a refractory material. It can be easily installed by inserting the refractory material. Moreover, since one or more projecting pieces are formed on the pair of left and right holding pieces toward the inside, it is possible to prevent the refractory material from coming out to the outside after being once attached to the mounting portion. Since the protruding pieces are provided on both sides of the surface of the backing plate main body, it can be easily mounted by inserting it into the earthquake-resistant slit material. On the back side of the backing plate main body, a pair of support portions that allow the support arm hanging on the separator holding the formwork to be slidable up and down are formed. The object of the present invention is to solve the above-mentioned conventional problems, for example, it can sufficiently withstand the lateral pressure of concrete and can be accurately arranged.
