Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building construction method.

[0002]

2. Description of the Related Art At present, there are many demands for shortening working hours such as two days off per week at construction work stations, but it is difficult to systematically set up holidays in the present situation because there are many construction works such as skeleton works that are affected by the weather. is there. On the other hand, the shortage of labor and the aging of workers in recent years have become major problems for the future of the construction industry. Therefore, various measures have been taken to solve these problems, but in the above case, a method of surrounding the entire work place with an awning or the like is adopted. In addition, in the case described later, some robotization is adopted at the stage of ground assembly such as rebar and formwork assembly.

[0003]

However, the method of enclosing the whole work place with the above-mentioned awning or the like has a drawback that a large amount of time and labor is required for refilling, especially in the case of reinforced concrete construction. Due to the difficulty of lifting and arranging the members, the work is actually forced to be stopped when it is raining or snowing. In addition, some robots at the assembly stage such as rebar and formwork assembly have poor feet,
There were many problems such as the fact that a large load could not be applied and the robot itself was difficult to transport to the upper floor, and it was still difficult to make a robot on the assembly floor.

The present invention has been made in view of the above problems, and an object of the present invention is to enable a skeleton work without being affected by the weather and to robotize the construction and the assembly work so that the labor It is to provide a building construction method capable of reducing time, improving workability, and eliminating labor shortage and aging of workers.

[0005]

[Means for Solving the Problems ] To solve the above problems
The means of the present invention for
A guide pillar is erected on the guide pillar, and a part of the guide pillar can be opened and closed.
A roof is installed so that it can rotate and slide freely.
A tower crane is installed in the section, and the lower surface of the roof is
Suspended freely on a guide rail that rotates in one direction
Build the skeleton with the broken assembly device,
By raising the erection roof and tower crane
It

[0006]

In this way, since the erected roof of a size that covers the building is slidably provided on the guide pillar that is erected in the center of the ground where the building is constructed, the structure of the skeleton Construction work can be performed, and as the skeletons are sequentially assembled, the erection roof rises upward, so that the skeleton construction work can be performed without being affected by the weather. In addition, a guide pillar that is erected in the center of the ground where the building is built is provided with a partially openable and closable erection roof that is rotatable and slidable, and the assembling device is suspended on the erection roof. Since the assembly device can be used without being affected by the condition of the floor surface, the construction and assembly work of the frame can be robotized, and the workability can be improved, labor shortage and the aging of workers can be eliminated. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 5 show a building in which a erected roof 2 of a size that covers the building A is slidably provided on a guide pillar 1 that is erected in the center of the ground M where the building A is constructed. It is sectional drawing which shows the construction method of. First of all, building A
A pile retaining wall N is placed on the ground M of the site to be constructed, and a large diameter foundation pile 3 is constructed on site. Then, the iron aggregate is inserted into the foundation pile 3 to build the temporary columns 4, and the guide columns 1 are erected by adding the iron aggregates to four of the temporary columns 4 (FIG. 1).

Next, the erected roof 2 is slidably attached to the guide columns 1 and the ground M is excavated to construct the floor slab 5 on the first floor (FIG. 2). The erection roof 2 is shown in FIG.
As shown in FIG. 7 and FIG. 7, a circular rotary roof 1 a and an assembled roof 1
b and the rotary roof 1a is a slide device 6
On the steel frame truss 7 radially protruding from the rotating body 6a of
It is formed by stretching the root plate 2a. Predetermination of this roof board 2a
An opening 2c is provided at that location, and a slur is inserted in this opening 2c.
The slide plate 2b is slidably attached to the slide plate.
Slide the plate 2b to open the opening 2c.
Allows PC members and other materials to be carried in.
ing. Therefore, by rotating the rotating roof 1a
The opening 2c can be set at any position.
Furthermore, the slide device 6 so that increases the erection roof 2 by sliding the result <br/> guide posts 1 the hydraulic jacks 6b
It has become (Figure 6).

Next, the ground M is sequentially dug down and the tower crane 8 is installed on the upper part of the erected roof 2 (FIG. 3).
This is to lift a building material and carry it in through the opening 2c of the erection roof 2, and to raise it with the rising of the erection roof 2 accompanying the assembling of the ground frame a.

Next, an underground skeleton b is constructed to the lowermost part, and an above-ground skeleton a is assembled to construct a building A. After all of these are completed, the erection roof 2 and the tower crane 8 are dismantled (Fig. 4 and Figure 5). As a result, the construction work can be performed under the erected roof 2 at all times without being affected by the weather.

Next, an embodiment of the construction method of the building A when the assembling apparatus 9 is suspended on the erected roof 2 will be described with reference to FIGS. First, similarly to the above, the mountain retaining wall N is placed on the ground M of the site where the building A is constructed, and the large diameter foundation pile 3 is constructed on site. Then, the iron pillars are inserted into the foundation piles 3 to construct the temporary columns 4, and the guide pillars 1 are erected by adding the iron aggregates to four of the temporary columns 4 (FIG. 8).

Next, the erected roof 2 is slidably attached to the guide pillar 1, and various assembling devices 9 are hung on the erected roof 2.
Floor slab 5 on the 1st floor by lowering and excavating the ground M
(Fig. 9). The erection roof 2 is the same as above
It consists of a circular rotating roof 1a and an assembled roof 1b.
The rotary roof 1a is the rotary body 6a of the slide device 6
The roof plate 2a is stretched on the steel frame truss 7 that is radially projected.
Are formed. An opening is provided at a predetermined position on the roof plate 2a.
2c is provided, and the slide plate 2b is slid into the opening 2c.
It is mounted so that you can ride freely, and slide this slide plate 2b
