Description

The present invention relates to an erected beam having a vertical adjustment function for constructing a slab such as a reinforced concrete structure.

Conventionally, when constructing a slab formwork such as a reinforced concrete structure, a large number of steel pipe posts are arranged in a forest, a joist is formed using a butter angle and a steel pipe, and a veneer formwork is laid to form a slab formwork. The up and down adjustment is adjusted by moving the steel pipe post up and down.

It is difficult to operate the leveling machine in the steel pipe posts arranged in the forest, and the vertical adjustment of the slab lacks accuracy. Moreover, the interior of the room where the walls and slab formwork are built is dark, making operation of the level machine more difficult.

Furthermore, loading and unloading a large amount of temporary materials such as steel pipe posts, butter angles, and steel pipes is a heavy labor. Moreover, the slab formwork using a large number of steel pipe posts, butter angles, steel pipes, etc. requires skilled skills and the disassembly of the slab form is dangerous.

Also, as a construction method that does not use steel pipe posts, peco beams that can be adjusted in length are used, but the function of these temporary beams is to adjust the length according to the interval of the beams that span the temporary beams. It is a function that only supports the load.

In addition, the following patent document can be mentioned as a well-known technique relevant to this invention.
