Description

TECHNICAL FIELD The present invention relates to a half-PC board that can be mounted unmanned using a labor-saving mechanical device such as an outer wall lifting device, and a mounting method therefor.

[Conventional technology]

Generally, a PC curtain wall or an aluminum curtain wall is adopted as a construction method for constructing an outer wall of a building structure. According to this method, a worker lifts the outer wall member lifted by a tower crane or the like from the inside of the building, grabs it, and pulls it to the mounting position to perform the mounting work.

[Problems to be Solved by the Invention]

This half wall PC board has been widely used due to the recent social background such as shortening the construction period at the site, labor saving, and lack of workers. However, the outer wall half-PC board mounting work currently used is basically manual work, and there is a limit to improving the work efficiency while improving the safety. Therefore, even if you try to install an outer wall by introducing a labor-saving mechanical device such as an outer-wall lifting device, the conventional half-PC board for the outer wall cannot handle it, and it seems that it is suitable for a mounting method that can be performed with a labor-saving mechanical device. In addition, it is necessary to improve the joints and joining methods of the outer half PC boards.

The present invention is for solving the above-mentioned problems, and an outer wall half that can be easily and quickly mounted by a labor-saving mechanical device.
The purpose is to provide a PC board and its mounting method.

[Means for Solving the Problems]

Therefore, in the present invention, the upper joining jig provided at the upper end is fitted and fixed to the mounting bracket of the outer girder, and the lower joining jig provided at the lower end is the upper joining jig of the half-PC board on the lower floor. An outer wall half that is fitted and fixed and is a PC plate that includes a plurality of hanging pieces for gripping and transporting in a horizontal state and a plurality of hanging pieces for gripping and lifting in a vertical state. After holding the horizontal transfer hanging piece of the outer wall half PC board by the PC board and the carrying device and carrying it horizontally from the stockyard, the outer wall lifting device holds the lifting piece of the outer wall half PC board for lifting the outer wall. Lifting up to the mounting position, pulling the half PC board to the wall side and dropping it down, the upper joining jig of the outer wall half PC board is the mounting bracket of the upper girder, and the lower joining jig is the lower floor half wall PC board. Mounting the outer wall half-PC plate that is fitted and fixed to the upper joining jig Law and said.

[Action]

The present invention provides a hoist for hoisting from a stockyard for horizontal transportation, a gripped portion for hoisting for hoisting to a mounting position of an outer wall, and a joining jig, respectively.
It is installed on the PC board in advance, and after carrying the outer wall half PC board to the site, it is transported and lifted to the predetermined outer wall half PC board mounting position by the labor-saving machine device, and the upper joint jig of the outer wall half PC board The groove of the side joining jig is fitted in the form of matching with the bolt of the mounting bracket of the upper girder and the bolt of the lower half outer wall half PC board upper joining jig, and then the fixing nut is tightened to fix it, so it is easy, It can be installed quickly, labor saving can be achieved, and safety and work efficiency can be improved.
