Various ideas have been proposed for buildings that combine the advantages of wooden buildings and the advantages of reinforced concrete structures. However, as related to the present invention, for example, “ Reinforced concrete exterior wooden building and its construction method ".

The “reinforced concrete exterior wooden building and its construction method” described in Patent Document 1 includes a foundation construction process for constructing a foundation in which a bottom plate portion is formed along the outer periphery of the rising portion, and an outer surface on the upper side of the rising portion. On the upper side of the bottom plate part outside the rising part, the wooden step of building the wooden building formed by the wooden board, the reinforcing step of arranging the reinforcing bars along the wooden board on the upper side of the bottom plate part outside the rising part Through a formwork installation process in which a formwork is placed on the outer side of the reinforcing bar, a concrete pouring process in which concrete is poured into the gap between the wooden board and the formwork, and a concrete curing process in which the concrete is cured, wooden construction The outer wall made of reinforced concrete is integrated with the outer surface of the object.

Japanese Patent No. 4879359

“Reinforced concrete exterior wooden building” described in Patent Document 1 has the advantages of being able to feel the warmth of wood and demonstrating the same strength as reinforced concrete. In terms of points, it is insufficient.

In particular, the wooden structure that constitutes the above-mentioned “steel reinforced concrete exterior wooden building” is formed of a wooden board on the outer surface, so that not only requires a lot of labor and time for construction, but also wiring the wall part formed of a wooden board. It is difficult to use as space for piping.

Therefore, the problem to be solved by the present invention is that the construction period can be greatly shortened and the construction cost can be reduced, the thermal insulation is excellent, the wall part can be effectively used, and the advantages of the wooden building Another object is to provide a building that combines the advantages of a reinforced concrete structure and its construction method.

The construction method according to the present invention is:

A bar arrangement process for arranging reinforcing bars in an area on the rising portion outside the plate material,
A step of standing a mold on the outside of the reinforcing bar with a separator interposed between the plate member,
Placing concrete between the plate and the formwork;
And a step of removing the mold after the concrete is solidified.

With such a configuration, a simple structure wooden frame structure can be constructed in a short period of time on the rising part of the reinforced concrete foundation, and the construction of the wooden part and the construction of the reinforced concrete part are alternately or in parallel. Therefore, the construction period can be greatly shortened and the construction cost can be reduced. That is, since it is possible to carry and assemble wood that has been precut at the factory, it can be constructed in a short period of time. In addition to the wooden frame construction method, it is also possible to use it in a pre-cut of the wooden two-by-four method and the light weight steel frame method.

In addition, because a plate material is interposed between the wooden frame structure and the wall part made of reinforced concrete, it has excellent heat insulation properties, and the space between the columns of the outer wall part of the wooden frame structure is between the columns. Since there is an effective space that can be used for piping and wiring, the wall portion can be effectively used. Moreover, in the conventional construction method, internal construction work (electrical wiring, water pipes, etc.) was completed before placing concrete, and then, after placing concrete, wiring and piping after placing concrete However, in the construction method of the present invention, since wiring and piping are performed after placing the concrete, there is an advantage that the wiring and piping can be arbitrarily changed.

Furthermore, since the inside of the building is made of wood with good texture and the outside is made of sturdy reinforced concrete, it provides a building that combines the advantages of a wooden building and the strength of a reinforced concrete building be able to. In particular, in Japan, it seems that using a wooden frame construction method will create a building and living environment suitable for the Japanese climate.

Here, in the construction method, as the separator, a wood screw portion that is screwed to the wooden frame structure from the outside of the plate material, and a base end side of the wood screw portion is coaxial with the wood screw portion. It is possible to use one provided with a separator shaft to be screwed and a P-con to be screwed to the base end side of the separator shaft.

Further, in the construction method, as the separator, a folded plate member bent into a folded plate shape, and the wooden structure penetrating through a valley portion of the folded plate member to fix the folded plate member to the outside of the plate member. It is also possible to use one provided with a wood screw that is screwed to the shaft assembly and a P-con that is screwed to the peak portion of the folded plate member.

Furthermore, in the construction method, as the separator, a separator shaft having a fixing metal member fixed to a front end side, and the wooden frame structure body that penetrates the fixing metal member to fix the fixing metal member to the outside of the plate member. It is also possible to use a screw provided with a wood screw to be screwed to the base and a P-con to be screwed to the base end side of the separator shaft.

On the other hand, in the construction method, it is desirable to erect the formwork in a state where the inner surface of the lower edge side of the formwork is in contact with the outer side surface of the rising portion.

Next, the building according to the present invention is
A wooden frame structure built on the rising part of a reinforced concrete foundation;
A plate material installed in a state in contact with the outer wall of the wooden frame structure or included in the outer wall;
A reinforcing bar disposed outside the plate member and in a region on the rising portion;
A wall part made of reinforced concrete formed in a region on the rising part in a state of being in close contact with the plate material and incorporating the reinforcing bar.

According to the present invention, the construction period can be significantly shortened and the construction cost can be reduced, the heat insulation is excellent, the wall part can be effectively used, and the advantages of the wooden building and the reinforced concrete building are obtained. It is possible to provide a combined building and a construction method thereof.
