Description

Wall structure using precast combined foundation rebar network and precast wall and its construction method {WALL STRUCTURE USING COMBINED PRECAST FOUNDATION REINFORCEMENT NETWORK AND PRECAST WALL USING AND ITS CONSTRUCTION METHOD}

The present invention relates to a wall structure, and more specifically, to a precast combination type foundation rebar network and precast construction in which both the floor foundation and the wall part are constructed in parallel with precast concrete and cast-in-place concrete without reinforcement or other high-altitude work. It relates to a wall structure using a cast wall and its construction method.

This part only provides background information related to the content of this application and does not necessarily constitute prior art.

A typical reinforced concrete structure is constructed through the process of arranging rebar, installing a form, pouring concrete into the form, and then curing it.

This on-site casting method requires the installation of forms and supports and reinforcement, and also requires a long concrete curing time, so the construction period is very long. Moreover, since the arrangement of reinforcement, especially vertical reinforcement, is done at high altitudes, it requires a lot of work by workers. There is a problem with safety accidents such as falls.

In addition, there is a disadvantage in that construction material waste is generated because a lot of construction materials (forms, scaffolding, scaffolding, etc.) are used.

To solve these problems, the precast method is used.

The precast method is a method of manufacturing precast concrete bodies (segments) of a certain shape and structure using molds in a factory, transporting these precast segments to the construction site of the structure, and assembling them on site. The construction period is from on-site casting. Although it has the advantage of being very short compared to the existing method, the existing method is composed of a full-section precast wall, meaning the entire precast segment is made of precast concrete, so it is very heavy, making it difficult and costly to transport to the construction site. .

The purpose is to provide a wall structure and a construction method using precast walls.

A wall structure using a precast combined basic rebar network and a precast wall according to the present invention includes a basic rebar network including precast; The first and second walls are connected with a hollow part in between, and the bottom part is supported by the foundation reinforcing bar network and is constructed in combination with on-site casting of concrete, including hollow precast wall panels that are erected at a certain distance from each other, and the foundation is constructed in combination with on-site casting. The reinforcing bar network is a precast concrete foundation panel, a reinforcing bar network arranged to be connected to the inside and outside of the precast concrete foundation panel, assembled or integrally formed on the upper part of the precast concrete foundation panel, and the hollow precast wall panel. This fixed wall fixing part includes a form part that is integrally formed or assembled at the edge of the precast concrete foundation panel to form a pouring space for on-site pouring of concrete, and the hollow precast wall panel includes the first, 2 The lower end of the main reinforcing bar embedded in the panel protrudes to the bottom and is fixed to the wall fixture.

It is characterized by including.

According to the wall structure and its construction method using a precast combined foundation rebar network and a precast wall according to the present invention, the foundation and the wall are made of precast concrete and in-situ casting in parallel to minimize separate reinforcement work at the site. By eliminating it, it has the effect of shortening the construction period and reducing costs. In addition, it has the effect of improving constructability and economic efficiency by eliminating the use of scaffolding by eliminating work at heights. The precast part functions as a formwork and the formwork is integrated into one piece. Since there is no need for workers (scaffolding, scaffolders, and form workers) for each process, it has the effect of reducing costs by minimizing the number of workers. Manufacturing costs are reduced by simplifying the structure of the basic rebar network and hollow wall panel and their connection structures. In addition to saving money, it has the effect of maintaining a solid bonding state both in the on-site pre-assembly state and in the completed construction state after on-site casting.

In addition, the assembly structure of precast and rebar makes it very easy to control the quality of the product, and the structure can be constructed robustly by maintaining uniform quality.
