Description

Construction method of pre-assembled wall using pre-assembled wall module

In the present invention, a horizontal joint protruding from one end of the pre-assembled wall module is inserted into and fixed at the end of the other adjacent pre-assembled wall module, so that the joint of both sides can be easily and reliably proceeded, and the on-site rebar reinforcement work and temporary construction process It is about the construction method of pre-assembled wall using pre-assembled wall module that can shorten the construction period by omission of.

In the reinforced concrete structure, each structural member is constructed in the order of curing by pouring concrete after reinforcing reinforcement at the site. Accordingly, a lot of manpower must be put into the site, a lot of time is required 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 concrete pouring, the installation and dismantling process of the temporary material must be added. However, these temporary materials cause inconvenience to the operator's passage, and there is a risk of causing a safety accident.

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

However, the precast concrete member is difficult to manufacture in a certain size or more due to manufacturing conditions, weight, or transportation burden, so there is a limit to the application of large-sized members.

Accordingly, a technology for a pre-assembled wall frame unit that can shorten the on-site construction process by pre-fabricating the pre-assembled wall unit has been developed (Registration Patent No. 10-1490756). The registration technology has the advantage of being able to eliminate the reinforcement work on site, and to install a formwork without temporary materials on the pre-assembled wall frame unit itself, which can greatly shorten the construction period.

However, the registration technology has a disadvantage in that the bolt fastening operation is cumbersome because the horizontal reinforcing bar is welded to the leg of the vertical support member and the vertical support members of the adjacent pre-assembled wall units are bolted to each other.

In addition, in order to be recognized as an appropriate reinforcing bar joint at the joint, the welding length of the horizontal reinforcing bar and the vertical support member must be secured beyond the specified value. Accordingly, there is a problem in that the vertical support member has to be overdesigned beyond the 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 while omitting reinforced reinforcement work on site when constructing a reinforced concrete wall, so that it is easy to secure the quality of the wall and ensure a sufficient working space in the site to ensure smooth passage of workers. And it is intended to provide a method of constructing pre-assembled walls using pre-assembled wall modules capable of preventing safety accidents.
