Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a construction method for a building, particularly a building comprising a three-story house mainly made of wood.

(Problems to be Solved by the Invention) Currently, there is an increasing demand for three-story houses due to the difficulty in obtaining residential lots and the need for effective use of land. For three-story houses, conventional wooden structures have pillar cross sections that are too large, and there are concerns about the overall strength of the structure, so this is not generally done. Many have reinforced concrete structures. However, since there is a large need for wooden buildings in residential buildings, there is a desire to develop construction methods for buildings that meet this demand.

This invention was developed to meet the above-mentioned needs.

(Means for Solving the Problem) This invention first arranges an elevator shaft having a load-bearing structure and a rectangular plane in the core part of a building, then installs a working crane on the elevator shaft in the core part, and Using a crane, beams are placed along the sides of the elevator shaft in a cross-shaped pattern, and pillars or thin walls are placed around the core portion, and then the roof is supported by the elevator shaft. This is a building construction method characterized by constructing a three-story building in this manner.

(Example) In Figures 1 and 2, the core of the building is first an elevator shaft A with a load-bearing structure and a rectangular planar shape.
Place. And this elevator shaft A
A power winding trunk elevator A1 is installed in the area.

In order to make elevator shaft A a load-bearing structure, it may be made of wood with an increased number of columns, or may be made of steel or reinforced concrete. Around the core elevator shaft A, columns 1 and beams 2, which form the frame of a wooden structure and have a thinner cross section than the normal design, are placed. At this time, the beams 2 are arranged in parallel with the elevator shaft A in a parallel grid pattern. This tree structure can also be a two-by-four structure. Then, using the elevator shaft A of the core part, the beam 2 is spanned, and the pillar 1 or the thin wall is written.

The third class roof of the roof shed is also supported by the elevator shaft A together with the pillar 1. The roof frame may be a wooden structure, a steel structure, or a combination of both. The roof can be completely prevented from sinking by using a steel structure or a combination of these and a core part with high structural strength.

In this embodiment, each of the third floors is mainly constructed of wood.

In the figure, 4 indicates a gauge, and 5 indicates an entrance/exit door.

FIG. 3 shows another embodiment, in which the first floor has a reinforced concrete structure or a steel frame structure, and the second and third floors are mainly wooden structures. The roof frame 3 is supported by the elevator shaft A together with the pillars 1.

As the elevator, a hydraulic or electric type elevator A2 is installed.

When constructing the above building, first construct the core elevator shaft A, then install a working crane on top of the elevator shaft A and use it to erect columns 1, beams 2, or wall panels of the two-by-four structure. .

When the elevator shaft A is made of steel or reinforced concrete, the column 1 may be attached to the elevator shaft, but the end of the beam 2 can be directly supported by the elevator shaft A.

(Effects of the Invention) The present invention has the above-mentioned configuration, in which the entire or second and third floors of a residential building or the like are mainly made of wood, a load-bearing structure, a rectangular planar elevator shaft is arranged in the core part, and the elevator shaft is placed on top of the elevator shaft. A working crane is installed, and the crane can be used to arrange beams along the elevator shaft in a grid pattern, and to construct columns and walls. Furthermore, the elevator shaft supports the roof and reinforces the wooden structure, making it possible to make the cross section of the wooden structural member thinner than in a conventional design. Therefore, a three-story building can be made mainly of wood structure. Furthermore, since the elevator shaft in the core is used as a platform for loading each member, construction efficiency is improved and economical construction is possible.

Claims (1)

[Claims] 1. First, place an elevator shaft with a load-bearing structure and a rectangular plane in the core of the building, then install a working crane on top of the elevator shaft in the core, and use the working crane to install a beam on the side of the elevator shaft. A three-story building is constructed by placing pillars or thin walls around the outer periphery of the core part, and supporting the roof by the elevator shaft. construction method for buildings.
