DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a building such as a high-rise building having a reinforced concrete structure, and more particularly to a construction method aimed at saving labor and semi-automatic construction work.

2. Description of the Related Art JP-A-49-124817 (E0)
4B1 / 35) shows the following construction method for the construction of prefabricated buildings. A temporary turret is built at a predetermined position around the building to be constructed, and a lifting means is provided on the temporary turret to lift construction materials upward, thereby carrying the materials (three-dimensional building parts or room units) to a predetermined height. In addition, the materials are transported horizontally over the already-built buildings, and the buildings are sequentially assembled.

When the building reaches a predetermined height, the temporary turret is jacked up, new components are added to the lower end of the temporary turret, the temporary turret is raised, and construction materials are further raised. To be able to

[0004]

In the above-mentioned conventional method, since the temporary tower is an independent vertically long structure, there is little problem as long as the height is not very high, but the height has reached a considerable level. The task of jacking up the temporary turret further and adding new components to the lower end is quite difficult,
The temporary tower becomes unstable and cannot be raised too high. This limits the height of buildings that can be constructed in this way.

[0005] In addition, after the material is lifted by the lifting means attached to the temporary turret, the material is conveyed laterally over the constructed building. The structure of the building must be capable of building, and there are restrictions on the buildings that can be constructed in this aspect.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to lift materials to a predetermined height by a lifting means attached to a temporary turret, and then transfer the materials to a transportation means such as a crane. The purpose of this is to make it possible to carry it freely in the horizontal direction by using, and to be able to stably jack up the temporary tower to a considerable height.

[0007]

Therefore, according to the present invention, a plurality of temporary turrets are built around a building to be constructed, and temporary beams are bridged between upper ends of these temporary turrets and arranged above the construction site. The temporary turret and the temporary beam are jacked up together with the temporary beam by taking in materials to the site by lifting and carrying means attached to the temporary turret and the temporary beam and building the building sequentially from below to above. A new structural member was connected to the lower end of the temporary tower.

[0008]

The material of the building is lifted upward by the lifting means attached to the temporary turret, and then transported laterally by a transport means such as a crane attached to the temporary beam to construct the building. Since the temporary beams are bridged between the upper ends of the plurality of temporary turrets, the stability is greatly increased compared to the case where the temporary turrets exist alone, and jack-up can be easily performed.

[0009]

FIG. 1 shows an example of a construction method according to the present invention. In the figure, reference numeral 1 denotes a building under construction. Two temporary turrets 2 and 3 are erected around the building 1 to be constructed so as to sandwich the building 1 and these temporary turrets 2 and 3
A temporary beam 4 is bridged between the upper ends of the components and is disposed above the construction site. The temporary turrets 2 and 3 and the temporary beams 4 have a steel truss structure.

Although not shown, a crane or the like is attached to the temporary turrets 2 and 3 as means for lifting construction materials, and the building materials are lifted upward from the ground.

A crane girder 5 is attached below the temporary beam 4, and an overhead traveling crane 6 traverses along the crane girder. The material raised to a predetermined height by the crane 6 is carried to a predetermined position above the building 1.

In order to jack up the temporary towers 2 and 3, the following mechanism is provided at the base. A jack base 7 is provided so as to surround the roots of the temporary turrets 2 and 3, and a plurality of jacks 8 operating in the vertical direction are attached to the upper part of the base 7. Then, a horizontal base plate 9 is attached to the lower end of each jack 8, and the temporary beam 4 is built on the base plate 9.

The building 1 under construction reaches a predetermined height,
When the temporary turrets 2 and 3 and the temporary beams 4 are raised, the jacks 8 arranged at the bases of the temporary turrets 2 and 3 are simultaneously operated to synchronize the base plates 9 and 9 at the lower ends of the temporary turrets 2 and 3. Then, new constituent members 10 and 10 are loaded into the lower ends of the temporary towers 2 and 3 and added. This operation is repeated according to the progress of the building.

[0014]

According to the construction method of the present invention, a plurality of temporary turrets are erected around the building to be constructed, and temporary beams are bridged between the upper ends of these temporary turrets, so that the whole is integrated. The stability is greatly improved compared to the case where the temporary turret exists alone, and the work of jacking them up can be performed very stably because the temporary turrets support each other via the temporary beams. By repeatedly adding a new component to the lower end of the temporary tower, the temporary beam can be raised to a considerably high position. And the material can be transported to the predetermined position by the lifting and carrying means attached to the temporary turret and the temporary beam, and the building can be constructed efficiently,
It greatly contributes to labor saving and semi-automation. Further, the present invention can be applied without being restricted by the structure and shape of the building, and a considerably high building can be efficiently constructed by the method of the present invention.
