Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a construction method for attaching wall panels of a building.

(Prior Art) Conventionally, wall panels are usually installed using the curtain wall construction method or the like without constructing scaffolding.

First, the wall panel is lifted by a truck or crane and transported to a predetermined installation location, where workers waiting to pull the wall panel and attach it to the building frame.

(Problem to be Solved by the Invention) However, in the conventional method described above, the unstable wall panel suspended in the air is pulled to the building frame and attached, which makes the installation process very time-consuming and dangerous. I had a problem.

In addition, since the installation space for the retsu car is required, there are various restrictions in terms of space at the construction site, and there is a problem that it cannot be carried out on sites where buildings are adjacent to each other, so-called narrow land.

Furthermore, since the wall panels were installed one by one, the construction period was long and construction costs were high.

In order to solve such problems,
Invention described in Publication No. 132861 and Utility Model Application No. 51-77837
A device described in the above publication is known.

It also includes panels that are made up of incidental equipment that would normally be installed on an exterior wall, such as a balcony unit.

(Means for Solving the Problems) In the wall panel installation method of the present invention, a plurality of fixed frameworks that also serve as wall panel guide rails are installed vertically on the outer peripheral surface of a building frame. The fixed frame assembly that also serves as a rail is attached to a support bracket provided at the end of the floor surface of each floor and is erected from the ground to the roof. The wall panel placed between the two wall panel guide rails also serves as a fixed frame, and the wall panel is set at a fixed interval between two wall panel guide rails. The wall panels are engaged with the dual-purpose fixed frame, and the wire ropes of the lifting device installed on the roof of the building frame are used to lift the wall panels one by one and temporarily fix them, and the lowest wall panel is attached to these two walls. After the body panels are fixed between the fixed frame that also serves as guide rails, the temporarily fixed wall panels are unfixed sequentially from the bottom and lowered onto the wall panel below, and the two wall panels are fixed. The fixed frame, which also serves as a panel guide rail, is clamped and fixed by fixing bolts provided on the above-mentioned fixing fittings of the wall panel, thereby forming the outer wall of the building.

(Function) The fixing bracket provided on the back of the wall panel is engaged with the fixing frame that also serves as a wall panel guide rail, and the wall panel is sequentially lifted upward and temporarily fixed, and then the wall panel located below is Then, fix them to the fixed frame that also serves as the wall panel guide rail.
