DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary structure used for supporting a formwork for forming a slab or a beam, a steel frame, or the like when constructing a concrete structure, a steel frame structure, a bridge girder, or the like. .

[0002]

2. Description of the Related Art For example, in forming a concrete structure, in order to form a slab or a beam on an upper floor, it is necessary to support a slab and a beam formwork from above a slab on a lower floor by a shoring.

Conventionally, as a support for supporting a slab form or a beam form, a pipe support or a temporary structure combining pipes has been used.

[0004]

By the way, the use of a pipe support has a problem that the supporting strength is extremely unstable and many trees stand on the floor, making it impossible to work or walk on the floor. Therefore, other operations such as loading of materials have to wait until the slab is solidified, which is a factor of reducing the construction efficiency of the concrete structure.

In a conventional temporary structure in which pipes are combined, vertical columns are successively extended upward, the vertical columns are arranged at predetermined intervals, and adjacent vertical columns are sequentially formed by horizontal bars and diagonal members. By joining, the structure is assembled in a jungle gym shape, so even in this case, the space between the vertical columns is closed by the crosspiece and the diagonal material, and the loading and unloading and walking of the material on the floor surface Etc. are difficult and there is no function as a scaffold.

In a conventional temporary structure, a lower frame provided between the uppermost vertical columns has a structure in which both ends of an upper horizontal rail are attached to the vertical columns in order to support a slab form or a beam form. Because of this, the strength of the column and the load bearing strength are weak, and the rigidity of the temporary structure cannot be increased.In addition, if the spacing between the columns is changed, the length of the lower frame must be changed accordingly. However, there are problems that the number of types of lower frames increases, material management and assembling of temporary structures become complicated, and the production cost increases.

Accordingly, an object of the present invention is to provide a path for carrying in / out materials or walking while supporting a slab formwork, a beam formwork, a steel frame, etc., and have a function as a scaffold.
There is no danger that the components will be removed and the passage will be formed on its own, and there will be no danger of lowering the load supporting force.
An object of the present invention is to provide a temporary structure capable of reducing the number of types of members by sharing members.

[0008]
