Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing a structure using reinforced concrete.

Reinforced concrete work involves form work, reinforcing steel work, and concrete work, all of which require a great deal of time and effort. Also, some of the various construction works mentioned above are t!
As these projects are carried out in parallel, a huge amount of construction materials and materials are delivered to the construction site at once, which not only makes arranging, processing and managing the materials extremely troublesome, but also takes up a considerable amount of space during construction. It will be occupied by the storage area for supplies and materials.

This invention was proposed in view of the above-mentioned circumstances, and when constructing a reinforced concrete structure, the amount of work required for formwork work, reinforcing steel work, and concrete work, as well as the amount of work required for the various types of work described above, are used. A construction method for constructing structures using reinforced concrete that allows construction to progress smoothly while equalizing the amount of construction materials and materials used, and that makes it extremely easy to arrange, process, and manage construction materials and materials. The purpose is to provide

The method for constructing a structure using reinforced concrete according to the present invention is to construct a structure planned in a cross-shaped or Y-shaped plan shape by having a plurality of wing parts protrude from a core part arranged as a common facility or equipment using reinforced concrete. During the construction, a series of various tasks were carried out, including assembling reinforcing bars for columns in the core and each wing section, assembling formwork for columns, beams, and floors, assembling reinforcing bars for beams and floors, and placing concrete. A multi-story structure made of reinforced concrete is constructed by shifting the work to the core section, then to each wing section, and then sequentially moving the same amount of work toward the upper floors of the structure. Therefore, according to the structure construction method according to the present invention, the series of the above-mentioned various operations in the core part and the wing part are performed with the same amount of work, so that time, effort, materials, and materials are concentrated on a part of the operations. Things like that.

This allows the entire construction work to proceed smoothly.

Further, since only some of the building materials and materials are brought in and used in large quantities, it is easy to arrange, process, and manage the building materials and materials.

Also, the large space of the priest is not taken up by the storage of building materials and materials.

Hereinafter, the method for constructing a reinforced concrete structure according to the present invention will be explained based on a reinforced concrete structure planned in a Y-shaped plan view.

The figure is a plan view of a mid-to-high-rise building planned in a Y-shaped plan, with a core part A where common facilities and equipment are located, and wing parts B, O, and D where living rooms, etc. are located. It is planned from The core part is the wing part B, (1
, D will proceed with construction one or two floors ahead of D.

In wing sections B, O, and D, reinforcing bars were assembled for the columns, and formwork was assembled for the columns, beams, and floors.

A series of operations including reinforcing bar assembly work for beams and floors and concrete pouring work, reinforcing bar assembling work for columns, formwork assembly work for columns, formwork assembly work for beams and floors, and reinforcing bars for beams and floors. Divided into 6 tasks: assembly work and concrete pouring work, these 6 tasks are carried out on wing section B, then wing section 0. The process is carried out in the direction of the upper floors of the building while shifting sequentially in the order of D. In other words, when assembling formwork for beams and floors and assembling reinforcing bars for beams and floors at lying section B.

In the wing section O, the formwork assembly work for the beams and floor sections and the reinforcing bar assembly work for the beams and floor sections have already been completed, and concrete pouring work will be carried out. In addition, concrete pouring work has already been completed at the wing section, and the next step, which involves assembling reinforcing bars for the pillars on the floor directly above and assembling the formwork for the columns, will be carried out at the wing section B.
Concrete pouring work was carried out at the wing section O, and in parallel with this, the reinforcing bars for the columns on the floor directly above were assembled and the formwork for the column sections were assembled at the wing section O, and the beams and floor sections were constructed at the wing section O. Perform formwork assembly work and reinforcing bar assembly work.

Furthermore, in the second stage, the reinforcement work and formwork assembly work for the column part on the floor directly above in wing part B is carried out 1! i-implementation 5
In parallel with this, formwork assembly work and reinforcing bar assembly work for beams and floors will be carried out at wing section 0, and concrete (4) pouring work will be carried out at wing section 0.

Thereafter, in the same manner, the above six operations are carried out sequentially in the direction of the upper floors of the building.

Next, when constructing a building planned in a cross-shaped plan with four wing parts protruding from the core part A, assembling the reinforcing bars for the columns, assembling the formwork for the columns, beams, and floors, The four tasks of assembling reinforcing bars for beams and floors and concrete pouring are carried out in the upper floors of the building while shifting them sequentially in each wing section. In addition, in the embodiment, the core part A precedes the wing parts B, O, and D by about 1 to 2 floors.

By using it as a transportation route for construction materials and materials and supporting wing sections B, O, and D during construction, work efficiency and work safety were improved.

As described above, according to the method for constructing a structure according to the present invention, construction can be carried out by averaging the amount of work for formwork work, reinforcing steel work, and concrete work, as well as the amount of construction materials and materials used for various works. This will allow for smooth progress. Furthermore, the arrangement, processing, and management of building materials and materials can be made extremely easy.

Claims (1)

[Claims] When constructing a structure with reinforced concrete that has multiple wing sections protruding from the core section and is planned to have a cross-shaped or Y-shaped planar shape, it is necessary to assemble reinforcing bars for the columns in the core section and each wing section, as well as for columns, beams, etc. A series of various operations such as assembling formwork outside the floor, assembling reinforcing bars outside the floor and beams, and pouring concrete were carried out on the upper floors of the structure while rubbing the core first, then each wing section sequentially fc 9f. A method for constructing structures made of reinforced concrete, which is characterized by being constructed in the same direction.
