Description

DETAILED DESCRIPTION OF THE INVENTION [Unexploded ψ] relates to a method for constructing girders on masonry walls of buildings constructed of ceramic blocks, bricks, concrete blocks, etc.

Conventionally, in order to dye the upper dC girders, a formwork was built at the upper end of the assembled structure wall using plywood, rafters, separator fittings, etc. Inside the formwork, VCC reinforcing bars were installed in advance and the comfleet tray was filled, and after it had hardened, Although the formwork is demolished, it takes a lot of time and effort to manufacture and dismantle the formwork, and since the formwork is disposable, it has the disadvantage of prolonging the construction period and increasing construction costs.

In addition, when constructors construct masonry walls and girders separately, VC has the disadvantage that the construction period becomes longer because it is difficult to coordinate construction procedures between each construction company. .

The present invention constructs a formwork by installing all outer frame plates of the same shape corresponding to the inner 1m and outer mlll surfaces of the girder to be constructed at the upper end of the assembled structure wall, and inside the formwork. After placing the reinforcing bars and filling the comfleet tray, the reinforced concrete layer is integrated with the outer frame plate as it hardens in the 7th stage. The purpose is to shorten the construction period and reduce construction costs by omitting the work of demolishing the formwork by arranging a part of the girder in the frame.
