Description

The present invention relates to hardware attached to a deck plate.

Conventionally, in the construction of concrete slabs, metal fittings for spacers have been used in order to secure an appropriate cover thickness for various reinforcing bars. Generally, metal fittings for spacers are installed on the formwork surface, and reinforcing bars are placed on top of it. However, in the case of thick slabs, the installation position of the upper end reinforcements is higher than the formwork surface, and the metal fittings for spacers act externally. The situation becomes unstable with respect to force. Since various construction loads are expected, such as a worker riding on a reinforcing bar during construction, a spacer that does not easily come off, fall, or move against an external acting force is required. For example, in Patent Document 1, a metal fitting for a spacer that supports a reinforcing bar is provided in a mold. Such hardware needs to be fixed to the formwork by welding. Further, as a hardware that can be easily installed without using welding, the one described in Patent Document 2 is known.
