Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of constructing a composite building having a wooden interior and a concrete exterior.

Conventional technology and problems Wooden buildings have the advantage of short construction times and good ventilation, but they are not built robustly using factory-produced building materials. It was difficult to use concrete for the exterior walls due to strength issues. Concrete buildings have the advantage that the aggregates are all steel frames and reinforcing bars, and that they do not require the use of internal or external formwork when pouring concrete, resulting in a sturdy building. This method has disadvantages such as the need for assembling and dismantling frames and the use of machinery such as cranes for construction, which inevitably lengthens the construction period and the need for a large work space.

The present invention was created by focusing on these problems.
Using predetermined wooden construction components pre-produced in a factory,
A composite building with a solid wooden interior and a concrete exterior can be completed in a short period of time, as well as a proposal for a construction method for a composite building that can be constructed without the use of machinery such as cranes, as well as improvements in heat insulation and soundproofing properties. The purpose of this paper is to propose a useful construction method for complex buildings that will lead to the construction of excellent complex buildings. - Means for solving the problem The present invention involves erecting columns at appropriate locations on the foundation, constructing an insulating floor for the lower floor using insulating floor panels over the inwardly extending portion of the foundation, and placing the insulating floor on top of the insulating floor. A concrete slab for the lower floor is constructed, and on the periphery of the concrete slab, a plurality of insulation side wall panels that also serve as lower floor formwork are erected in parallel with the insulation material on the outside and the space on the inside. An insulated ceiling for the lower floor is constructed using an insulated ceiling panel over the side wall panels, and concrete is poured between the outer formwork for the lower floor and the insulated side wall panel that also serves as the inner formwork for the lower floor and on the valve of the insulated floor. Construct the concrete slab for the lower floor m7<-r concrete side wall and the upper floor, then construct the upper floor concrete slab with the insulation side wall panel that also serves as the inner formwork with the insulation material on the outside and the space on the inside. The insulation ceiling for the upper floor is erected in parallel on the peripheral edge of the insulation side wall panel, and the insulation ceiling for the upper floor is constructed over the insulation side wall panel, and the insulation ceiling for the upper floor is installed between the outer formwork for the upper floor and the insulation side wall panel that also serves as the inner formwork for the upper floor. Concrete was poured on top of the insulation ceiling, concrete side walls for the upper floor and a concrete slab for the upper floor were constructed, and the upper floors were constructed one after another by repeating the above lower floor construction method. The proposal is to install the roof on top of the concrete slab on the top floor and then dismantle the external formwork.

Effects The present invention uses factory-produced homogeneous wooden building components such as insulated floor panels, insulated side wall panels, and insulated ceiling panels, so it is possible to construct a sturdy wooden building, and the exterior can be made of concrete. There is also no need to worry about damage to the internal wooden structure.

These building components are made of wood, heat insulating materials, etc., making them lightweight, making them easy to transport without the use of cranes, etc., and using heat insulating side wall panels as inner formwork. It can also be used for concrete pouring, and used as a wooden building without being dismantled. Therefore, it is possible to work in a narrow work space, and the construction can be carried out efficiently by not dismantling the heat insulating side wall panels, which has the effect of shortening the construction period. In addition, the constructed composite building is constructed using a heat insulating side wall panel with a heat insulating material attached to one side and a space formed on the other side, with the heat insulating material on the outside and the space on the inside. Not only does the outer insulation material have a heat insulation effect, but the inner space also provides heat insulation and soundproofing effects, offering excellent insulation performance.
It also has the effect of having excellent soundproofing properties.
