METHOD FOR CONSTRUCTION INDOOR DOUBLE FLOOR STRUCTURE [0002]

The present invention relates to an indoor double-layer structure and an indoor double-layer structure construction method, and more particularly, to an indoor double-layer structure and an indoor double-layer structure that enable an indoor double- To a method of constructing a multi-layer structure.

In recent years, urban residential properties such as office buildings, office rooms, and the like have been constructed in accordance with the miniaturization of residential space. In such an urban living house, a multi-storey structure that divides the indoor space by increasing the floor height for one floor may be applied. Therefore, even a small indoor space can be divided into two upper and lower spaces, so that various activities can be performed in separate spaces.

Generally, the multi-layered structure forms a middle floor in the interior space and divides the interior space into the upper and lower layers. Here, the lower layer is an indoor space formed on the lower side of the middle floor, and is used as a space for office work or living, i.e., a dynamic space, and has a relatively high ceiling. Further, the upper layer is used as a space for taking a rest or sleeping, i.e., a static space, and has a relatively low ceiling, and at least one side is opened.

On the other hand, the construction of the middle layer dividing the indoor space into the upper and lower layers in the multi-layer structure is very important. In order to maximize the utilization of the indoor space, the middle layer must have a relatively thin thickness, be structurally stable, and be easily installed. In addition, the middle layer should have a light weight and good flame retardancy against fire and good water resistance against moisture or moisture. The middle layer for the multi-layer structure consists of a reinforced concrete structure, a steel structure, and a wood structure.

The middle layer of the reinforced concrete structure consists of a concrete layer with reinforcing bars arranged. This middle layer has a relatively large load. The formwork must be installed in the interior space, and it takes time to transport the material for the formwork installation and to construct the formwork. As a result, the middle layer of the reinforced concrete structure requires a considerable construction time, and the work process is complicated. Also, since the curing process is performed after the concrete is poured, the construction period is further increased. Therefore, the multi-layer structure needs to be installed safely while reducing the construction time when it is installed in an indoor space.

A method for constructing an indoor multi-layer structure according to a preferred embodiment of the present invention aims at quickly and firmly constructing a multi-layer structure in an indoor space.
