It can be carried out.

Next, other embodiments of the present invention will be described.

This embodiment is a method suitable for use when building columns and beams on the lower floor below the columns on the first floor.

First, as shown in FIG.
The pillars 22 and 22 are joined to assemble the pillar and beam unit 24. Since the column and beam unit 24 is symmetrical, the center of gravity is located at the center.

A whistle l-16 disposed on the horizontal conveyance means I8,
This column and beam unit 24 is suspended and supported.

On the other hand, the temporary support is supported by the boat support 26 so that the interval between the previously constructed main columns 8.8 is longer than the length of the columns 22.22 to be erected.

The columns 22.22 can be held vertically by hanging them with hoists 16 at the center of the column and beam units 24.

The hoist 16 is moved along the horizontal transport means 18 to transport the column and beam unit 24 to a predetermined position.

The temporary support adjusts the length of the upper support member 26 to set the interval between the previously constructed main pillars 8.8 to the regular position.

When constructing a building using this upper pillar and beam unit 24, as shown in FIG. By transferring it to the means 18, the beam and column units 24 are joined at a predetermined position.

According to this embodiment, when the pillars on the lower floor were erected below the main pillars 8 on the first floor that had been constructed in advance, the columns 24 were safely transported to the column and beam unit 1 by the horizontal transport means 18 of the tower crane IO1. Since the work is carried out later, the work can be easily carried out in the same way as normal construction work without requiring any skill.

Furthermore, since the column and beam units 24 are assembled symmetrically, they can be easily balanced without the need for any special balancing jig when hoisting I and gating with the hoist 16, which improves work safety. I can do things by directing people.

"Effects of the Invention" According to the method and device for constructing a building according to the present invention, it is possible to simultaneously perform the work of joining columns and beams located between the layers of each composite beam in multiple layers. Therefore, it is possible to shorten the construction period.
