Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a construction method for attaching wall panels, such as ALC panels (autoclaved light weight concrete panels), to the steel frame of a building.

The vertical wall insertion reinforcement method is known as a method of attaching this type of wall plate to a steel frame structure, but as shown in Figure 8, the conventional method is to weld the angle b through the beam a of the frame. After marking the installation horizontal line of the wall board c on this angle b, and marking the assignment ink for each width dimension of the wall board c, weld one vertical wall plate d to the intersection of these marks, and then The erection is carried out by placing both ends of the lower end surface of the wall plate c on the adjacent plates d and d.

It is difficult to accurately set the joint spacing between the upper end surface of the lower wall plate c and the plate d, which has already been erected, and the position of the through angle b may vary depending on the height position of the beam a of the frame. This method has the disadvantage that it cannot deal with on-site errors or changes because the

Furthermore, as mentioned above, the through plate d is welded to the through angle b after setting the mounting position of the wall plate c, so the work is not only troublesome but also requires scaffolding. Therefore, the workability is extremely poor, and there is a problem that the erection work of wall boards cannot be carried out efficiently.

The present invention provides a construction method that eliminates such problems.
