Description

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 using PC members, and more particularly to a method for installing an interior immediately after PC members are constructed in a corresponding section.

[0002]

2. Description of the Related Art For example, when a multi-story apartment house such as an apartment building is constructed of PC members, it is common to carry out skeleton work using the PC members and then assemble interior materials inside the skeleton.

[0003] However, in this construction method, the size of the interior material and the setup work for assembling are limited by the opening of the skeleton, and in the case of a large interior material, a large opening such as a veranda is required. Can only be brought in,
The work was troublesome.

Therefore, as a construction method of a building using PC members, for example, Japanese Patent Application Laid-Open No.
There is disclosed a method of assembling a member incorporating an interior material inside a C member while sequentially lifting the member to a predetermined position.

The construction procedure in this construction method includes:
As shown in FIG. 3, an interior material manufactured in an interior material manufacturing factory or the like is assembled to a PC member manufactured in a PC member manufacturing factory or the like, and then integrated by packing, curing, etc., and the integrated member is constructed. It is a method of completing the framing work and completing the interior at the same time by carrying it to the site and performing lifting assembly, which is suitable for shortening the construction period.

[0006]

However, in this method, in order to assemble different kinds of members in advance, it is necessary to transport one of the members to a manufacturing factory of the other member, and to unload and unload the members. It took time.

[0007] Further, in the assembled state, since it is a composite member of different materials, it must be transported after taking measures to prevent damage such as packing, and these packages must be unpacked at the time of assembling the frame or after assembling. However, a large trailer is required because of the large size and large weight, and problems such as securing a passage for transportation have arisen.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to assemble PC members and assembling of interior materials alternately at a construction site, thereby improving the efficiency of interior construction and transporting. PC that can solve various problems
An object of the present invention is to provide a method for constructing a building using members.

[0009]

In order to achieve the above object, the present invention provides a method for mounting a pillar made of a PC member at a corner of a slab consisting of a PC member installed at a predetermined position. After loading and installing the prefabricated interior material unit in the section to be partitioned, install the PC beam on the upper part between the columns, assemble it between the columns, and then repeat the work of arranging the slab for each floor It is characterized by the following.

Therefore, according to the method of the present invention, the interior material unit can be suspended and carried in at a stage where the slab of the upper floor, that is, the ceiling is not installed, so that a large area interior material can be supplied at one time. Further, after the loading work is completed, the installation work of the interior material and the slab work of the beams and the ceiling can be performed in parallel, and there is no problem in the work setup.

Further, in the present invention, preferably, the interior material unit is formed in a size corresponding to a room size or a column span size, so that labor for interior work can be saved.

[0012]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG.
4 is a flowchart showing the working steps of the method of the present invention.

First, in step ST1, the PC member manufacturing plant and the interior material manufacturing plant independently operate P
Manufacture C members and interior materials. The members manufactured at the PC member manufacturing factory are PC slab materials, PC columns, PC beams, and the like.

The interior materials manufactured at the interior material manufacturing plant include a large double-wall panel and a large interior wall panel, which are manufactured in accordance with design dimensions such as a previously designed column span. In addition, necessary piping and equipment can be assembled to these.

Next, in steps ST2 and ST3, each member is transported to the construction site in accordance with the construction start time, and stocked in the stock yard at the site.

Next, in steps ST4 and ST5, a PC slab material is placed on a prefabricated foundation and cast-in-place slab concrete (when the PC columns and PC beams are half precast products, they are cast into their hollow portions. Including concrete to be installed), and then the PC
Pillars are built.

After the above construction is completed, step ST
6, In ST7, the large-sized double-panel panel is carried in from the ceiling opening surface, and installation is carried out.

Then, immediately in steps ST8 and ST9, Pc
The work of assembling the Pc beam to the column and the work of assembling the Pc slab on the upper floor are performed, and the work of placing concrete in place is performed. During the process of steps ST8 and ST9, there is little interaction between the interior material work and the skeleton work, so that the interior work or the interior finish work can be performed in parallel with the skeleton work.

The above operation is repeated up to the construction plan floor (step ST10). When the operation is performed up to the top floor, the operation is completed.

FIG. 2 shows a concrete construction structure of the above-mentioned work process. At present, the floor work and the installation of the Pc column 1 are completed at a predetermined floor F, and a large double floor is installed inside the floor work. It shows a state where the panel 2 and the large wall panel 3 are installed. Note that both the double floor panel 2 and the wall panel 3 have a member size corresponding to the span of the column 1.

On this pillar 1, a Pc beam 4 is further connected. The ceiling is covered with a Pc slab 5, and the upper part of the slab 5 is covered with cast-in-place concrete 6, and the next floor F + 1
Column 1 is assembled.

With the column 1 assembled, the double floor panel 3 of this floor F + 1 is hung down and installed and fixed on the slab by a large crane or the like, and then the wall panel 2 is also hung down to a predetermined position. Installed and fixed.

In this state, the Pc beam 4 is connected to the column 1 and then the Pc slab 5 is installed.

During this work, interior work or interior finish work can be performed in parallel.
Assembly of members and loading and installation of interior materials can be performed alternately for each floor.

[0025]

As is apparent from the above description, in the method for constructing a building using the PC member according to the present invention,
Conventionally, when building a building in a state where the interior material is assembled inside the PC member in advance, it is possible to eliminate troubles such as defects at the time of member assembly and packaging problems for curing, which are inherent problems, and labor such as transportation. Since the interior material can be carried in from the large opening portion, the carrying-in work and subsequent assembling workability are also improved.
