Description

Square bar fixing clamp for mold

The present invention relates to a clamp for clamping lumber, and more particularly, to shorten the air of the reinforced concrete structure and to reduce the construction cost by allowing the panel and the wood slab disposed on the upper panel to be easily fastened in order to extend the overall height of the panel. The present invention relates to a neck clamp that can be lowered.

When building an apartment or other high-rise building, in order to pour concrete, formwork is usually formed by a plurality of panels manufactured to have a predetermined area. In other words, by extending a plurality of panels in the longitudinal and transverse directions, and placing the concrete in a space formed by standing up to face the panels in such a state, as the curing of the concrete to form a wall forming the building.

On the other hand, these panels are largely classified into gangform, euroform and aluminum foam, where gangform refers to all panels made of iron plate, and the Eurofoam is made of plywood on the surface contacting with concrete and the profile of the plywood is settled, and the yoke · Jang Sun-jae refers to a panel made of metal and light in weight.
