Description

Unit block system

In the present invention, when constructing a modular structure by stacking unit blocks up and down, a guide block protruding from the upper end of the column member of the lower unit block is inserted into the lower end of the column member of the upper unit block to easily attach the upper and lower unit blocks to the correct position. There is, and it relates to a unit block system that does not lower the bearing strength of the column member.

The roof structure installed on the roof of a building is often constructed using the Reinforced Concrete (RC) method as in the reference floor.

However, because the roof structure has a different planar shape from the reference floor, the existing system formwork used for the construction of the reference floor, such as a gang form, cannot be used. Accordingly, the construction is performed using a separate conventional formwork.

These rooftop structures are generally constructed at the end of the framing work. Accordingly, there are restrictions on the use of equipment such as tower cranes, and there are difficulties in the supply and demand of on-site manpower or materials, which makes construction difficult, and there is a problem of delay in construction. In addition, when constructing a rooftop structure using a conventional method, there is a limit to quality assurance, and there is a risk of safety accidents because reinforcement, formwork installation and dismantling, as well as concrete pouring work are performed at high altitude.

Recently, the application of the modular method of manufacturing unit modules in a factory and then assembling them on site is increasing to replace these conventional methods.

In the modular construction method, most of the processes such as finishing, equipment, etc. are performed in advance in factories, etc., so it is possible to secure the quality of the structure and shorten the construction period. In addition, since the completed unit module only needs to be assembled at the site, it is possible to minimize the input of on-site manpower, thereby preventing safety accidents.

However, when the column is a square tube, the lower end of the column must be cut in order to fasten the high-strength bolt, so that a cross-sectional loss occurs, so that the internal strength of the column cannot be fully utilized. In addition, since the bolt fastening operation must be performed inside the cross section of the column, there is a problem of poor workability.

In order to solve the above problems, the present invention is to provide a unit block system that is easy to construct when assembling by stacking unit blocks up and down in a modular structure.
