Sheet connecting fitting for butt joint surface smoothing

Abstract

This article is a connecting fitting for connecting a partition board used to prevent the cast concrete from entering the gap between the arranged concrete joint materials and roughing the joint surface of the covering part when forming the concrete joint surface by arranging the concrete joint materials, and a support member that supports the partition board on the reinforcing bars. It comprises a partition board fitting part that fits into the upper part of the partition board that partitions the area where the concrete is cast on the reinforcing bars, a support member engaging part that engages with the support member fixed to the reinforcing bars at a position horizontally separated from the position where the joint surface is located by a predetermined distance outside the area, and a connecting part that connects the partition board fitting part and the support member engaging part. As shown in Reference Figures 1 to 2 showing the usage state, first, the support member is fixed to the reinforcing bars at a position horizontally separated from the position where the concrete joint surface is located by a predetermined distance. Next, the partition board is arranged at the position where the joint surface is located, the support member is inserted into and engaged with the support member engaging part, and the upper part of the partition board is inserted into and fitted into the partition board fitting part, so that the partition board is fixed to the reinforcing bars via the support member. Then, the concrete joint material is inserted from above between the partition board and the support member, and the concrete is cast. When the concrete is cast, the flow pressure of the concrete acts on the partition board. However, since this article connects the partition board and the support member fixed to the reinforcing bars, it is difficult for it to shift or fall from the fixed position.
