The prefabricated wall module of the present invention, which is for constructing a concrete wall structure, comprises: a plurality of main steel materials which are vertically arranged on the inner opposite sides of a wall structure; a plurality of horizontal support members for horizontally connecting the main steel materials adjacent to each other in the width direction; a plurality of spacing support members for connecting the main steel materials facing each other in the thickness direction; and a horizontal coupler which is formed to protrude from one side end or opposite side ends of the prefabricated wall module and inserted into the side end of another prefabricated wall module adjacent thereto.

Description

Pre-assembled wall module

The present invention allows the joints of both walls to be easily and reliably progressed by inserting and fixing the horizontal joints protruding at the ends of the one-sided pre-assembled wall modules at the ends of the adjacent other pre-assembled wall-modules, and on-site rebar reinforcement work and temporary material construction process The omission is for a pre-assembled wall module capable of shortening air.

In the reinforced concrete structure, construction of each structural member is performed in the order of pouring concrete and curing it after rebar reinforcement at the site. As a result, a lot of manpower has to be put into the field, it takes a lot of air for related construction, and it is not easy to secure quality.

In addition, since the formwork must be supported by an external temporary material before pouring concrete, the installation and dismantling process of the temporary material must be added. However, such a temporary material may cause inconvenience to a worker's passage, and may cause a safety accident.

Accordingly, in recent years, the use of precast concrete members factory-produced for the construction of reinforced concrete structures is increasing.

However, since the precast concrete member is difficult to manufacture to a certain size or more due to manufacturing conditions, heavy load, or transportation burden, there is a limit to the application of the large member.

Accordingly, a technology has been developed for a pre-assembled wall framing unit that can shorten the construction process by pre-fabricating the pre-assembled wall unit (Registration Patent No. 10-1490756). The registration technology has an advantage in that it is possible to omit on-site reinforcement work, and it is possible to install a formwork without a temporary material on the pre-assembled wall framing unit itself, thereby greatly reducing air.

However, the registration technique has a disadvantage in that bolting work is cumbersome since the horizontal reinforcing bar is welded to the leg of the vertical support member and the vertical support member of the neighboring line assembly wall unit is bolted to and interconnected.

In addition, in order to be recognized as a suitable rebar joint at the joint, the welding length of the horizontal reinforcing bar and the vertical support member must be ensured. Accordingly, there is a problem in that the vertical support member must be over-designed over a required cross-section to secure the welding length.

In order to solve the above problems, the present invention can install a formwork without temporary materials with omission of on-site rebar reinforcement work when constructing a reinforced concrete wall, so it is easy to secure the quality of the wall and secure a sufficient work space within the site for smooth passage of workers.
