BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support device for a temporary work for supporting a supported object such as a form panel in a temporary work at a building site.

[0002]

2. Description of the Related Art Conventionally, when supporting an object to be supported in building construction, for example, a form panel assembled at the time of pouring concrete, a square member or the like is applied to the outside of the form panel, and this is nailed and fixed. There are many methods for supporting and reinforcing a form panel.

[0003]

However, when the formwork panel is supported by nailing of the formwork as described above, the force for supporting the formwork panel depends on the strength of the formwork. As a result, the force for supporting the formwork panel increases, and it is difficult to cope with the nailing of the square material as in the related art. Therefore, in order to increase the supporting force of the formwork panel, the number of nails may be doubled by using a large number of square bars having a large diameter.In this case, not only the labor of nailing is increased but also the temporary work becomes complicated, There is a problem that it takes time to remove nails and the dismantling work becomes troublesome. The present invention solves the above-described problem, and supports a form panel or the like with a member having strength greater than that of a square bar, and increases the supporting force without performing many nailing operations, thereby increasing the size of temporary construction work. It is an object of the present invention to provide a temporary construction support device capable of efficiently performing temporary work and dismantling work on site.
