Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit framework construction method for general wooden houses, terrace houses and other wooden structures.

[0002]

2. Description of the Related Art Conventionally, as a building construction method for a wooden house, there has been known a construction method using a frame structure which is a conventional construction method using a lot of braces and metal. Further, as another building construction method, there is known a so-called prefabricated construction construction method in which standardized members such as floors and walls are assembled and processed in a factory in advance to reduce on-site work as much as possible. The prefabricated building is roughly classified into lightweight steel frames, wooden panels (panel type prefabricated construction method), and precast concrete. In particular, the panel-type prefabricated construction method is a simple construction method in which walls, floors, and roofs are made from panels made of plywood glued to a wooden frame, and has the advantage of easy on-site assembly and less waste. . Furthermore, there is a two-by-four construction method called the so-called frame wall construction method, which is called after the cross-sectional dimensions of the main timber.

[0003]

However, in the conventional example, all the building frame members for the entire construction area of a wooden building are preliminarily machined in the factory as parts based on the configuration of a fixed distribution pattern. Therefore, when the frame member is assembled on site, it is not easy to change the combination of the parts of the frame member, and the degree of freedom in changing the floor plan and the like cannot be used. For example, at the installation site, when changing the relationship between the adjacent road and the entrance position, the distribution pattern due to the family, etc., in the case of expansion, remodeling, etc., it is not possible to deal with this sufficiently and immediately, However, there was a problem that the design change had to be made at the stage of machining parts, which was rather expensive and complicated work.

The present invention has been made in view of the above-mentioned problems, and the degree of freedom of changing the floor plan or the like can be obtained even if an existing part is used as the construction frame member by the conventional construction method of the field assembly type. Another object is to provide an inexpensive and simple unit construction method for wooden buildings.

[0005]

In order to achieve the above-mentioned object, according to the present invention, in a construction method of a wooden building which is framed by a field assembly method, a frame structure of the first floor by the frame construction method is used. The body is composed of a plurality of frame assembly unit structural parts so as to form at least two or more compartment distribution compartments, and the adjacent frame assembly arrangements of the frame assembly unit structural parts are appropriately changeable, thereby achieving a room layout. It is a unit framework construction method for wooden buildings, which is characterized by giving flexibility to compatibility.

[0006] Further, the second-floor frame structure structure may be constituted by a chiseling structure unit so as to cover the entire first-floor frame unit structure part, or the first-floor frame unit structure part may be provided with a distribution room, respectively. It is possible to install a through pillar that allows the shaft assembly to be reassembled or added by changing the. Further, the frame structure on the first floor is provided with a base beam part having a variable frame form so that the layout of each of the compartments formed by partitioning can be changed, and the base beam part is erected on the base beam part. It is composed of a pillar portion and a through pillar that are partitioned into a plurality of frame unit structure portions, and a barrel portion that is arranged above the pillar portion, and the second floor frame structure body is the first floor frame structure structure. It is characterized in that it has a through pillar that is integrally extended from.

In the unit construction method for wooden buildings according to the present invention, the layout can be interchanged at the installation site by appropriately changing the adjacent arrangement of the construction units of the construction units. Room pattern changes, expansion,
Remodeling is simple and inexpensive. In addition, since the frame structure of the second floor is composed of the gassho structure unit so as to cover the entire structure part of the frame unit of the first floor, only the outer wall around the building with respect to the whole frame structure of the first and second floors. Can maintain sufficient strength. Since there are no extra columns or walls in the interior of the framework structure on the second floor, it is possible to freely configure the number of rooms and the room shape around the stairs, for example.

As shown in FIG. 7, the first-order frame structure 1A composed of a girder-shaped girder member 5 for arranging the main body and the through column 4 are extended upward, and a girder member is provided above the through column 4. 6 is laterally framed, and is composed of a frame structure 1B on the second floor that forms a gassho roofing unit by installing a gassho roof member 7 on the girder material 6.

At this time, the shaft structure of the through column 4 and the girder member 6, and the support column 3 or the through column 4 and the body inserting member 5 is conventionally a sickle joint or a sledge joint, which is shown in FIG.
As shown in FIG. 9, a pair of joining metal fittings 8 on the tongue protruding from the side surface of the column 3 or the through column 4 are fitted into the split grooves 6A and 5A formed at the end of the beam member 6 or the body inserting member 5. The driving pin 10 is fixed to the side of the girder member 6 or the barrel member 5 so as to penetrate the joint fitting 8 to be integrated. Further, the frame structure of the foundation beam member 2, the large beam member 2A, the beam member 5A, the girder member 6 and the like is, for example, a precut seat dovetail joint or a seat sickle joint (not shown) formed by a conventional construction method. Done through.

The foundation beam member 2 constituting the first floor frame structure 1A has a variable frame form so that the floor plan of each of the compartments partitioned and formed can be arbitrarily changed. Specifically, as shown in FIG. 1 and FIG. 2, the through columns 4 are provided at four corners on each of the foundation beam members 2 in which the floor plan is formed.
Is erected and each of the constituent units of the first-order frame assembly unit is formed in a block shape, and is divided into a first unit part A, a second unit part B, and a third unit part C. . In addition, as shown in FIG. 10, in the middle of the through column 4, a column connection fitting 9 that is provided at a required place over the base beam member 2 and the body insertion member 5 is provided.
