Description

  The present invention relates to a diagonal support for a pipe support used mainly for adjustment of a wall formwork.

When constructing a wall of a concrete structure, attach the upper end of the inclined pipe support to the horizontal end thick material of the wall formwork, and attach the square base plate on the lower end to the receiving bracket attached on the concrete slab. The pipe support is supported by the wall mold so as to be supported, but in order to support the base plate by the metal fitting, the rising piece provided at the tip of the metal fitting (the wall mold side) is used. There is a structure in which the base plate is disposed so as to pass between an upper end and the concrete slab surface, and receives a load from a pipe support to support a wall formwork (for example, Patent Document 1).
