Description

[Technical Field]

[0001] The present invention relates to a method for constructing a wooden building. [Background technology]

[0002] While traditional construction methods (wooden frame construction) are mainstream for wooden buildings in Japan, wooden frame wall construction (two-by-four construction) is also popular. Wooden frame wall construction is characterized by its ability to disperse earthquake and other forces and provide high earthquake resistance because it is a structure that supports the building on a surface. Furthermore, wooden frame wall construction has fewer types of structural members than wooden frame construction, and the work is streamlined, so it does not require advanced carpentry skills. Furthermore, in recent years, not only wooden frame construction but also wooden frame wall construction has been shortened in construction sites by pre-cutting at factories (see, for example, Patent Document 1).

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-97181 Summary of the Invention [Problem to be solved by the invention]

[0004] However, pre-cutting lumber is costly. In addition, because the locations where each piece of pre-cut lumber will be used are predetermined, all lumber is numbered, and it is necessary to select the correct piece by checking it against the blueprint when assembling. However, since all lumber looks similar, it is very confusing and even finding the lumber you need is difficult.

[0005] Therefore, the object of the present invention is to provide a method for constructing wooden buildings that does not require pre-cutting, does not require numbering, and can be constructed at low cost by minimizing the number of types of lumber. [Means for solving the problem]

[0006] The wooden building construction method of the present invention is characterized by the use of only square timbers cut to the same predetermined length as structural materials.In the wooden building construction method of the present invention, only square timbers cut to the same predetermined length are used as structural materials for the main structural parts such as the foundations, pillars, girders, joists and ties that form the framework that supports the wooden building, i.e., structural materials that support the structure of the wooden building, so it is easy to know which square timber to use in which place at the construction site.

[0007] Here, it is desirable to join structural members together using screws for wooden construction, which allows structural members to be easily joined together simply by driving in the screws for wooden construction, without the need for tenon, dovetail, or hook processing.

[0008] The method for constructing a wooden building of the present invention is characterized by creating a structural drawing that uses only timbers cut to the same predetermined length as structural materials. This makes it possible to easily construct a wooden building according to the structural drawing that uses only timbers cut to the same predetermined length as structural materials, and makes it easy to understand which timbers to use in which locations at the construction site.

[0009] Furthermore, in the wooden building construction method of the present invention, it is desirable that the number of types of timbers cut to the same predetermined length be four or less. By using only four or less types of timbers cut to the same predetermined length as structural materials, it becomes easier to determine which timbers to use in which locations at the construction site.

[0010] Furthermore, in the method for constructing a wooden building of the present invention, only square timbers cut to the same predetermined length are used as structural materials, and structural boards are joined to the framework formed by these structural materials, thereby obtaining a wooden building using a new wooden frame wall construction method. [Effects of the Invention]

[0011] (1) Since only square timbers cut to the same predetermined length are used as structural materials, it is easy to know which square timber to use in which location at the construction site, pre-cutting is not required, and no numbering is required, making it possible to minimize the number of types of wood and build at low cost. (2) Since pre-cutting is not required and the timber only needs to be cut to the specified length, no advanced skills are required and anyone can easily build. In addition, leftover materials are minimized, resulting in no waste and being environmentally friendly. (3) Since no numbering is required, it is possible to prepare and stock lumber cut to the same specified length. (4) Since structural materials are joined together using screws for wooden structures, advanced techniques such as tenoning, dovetailing, and hooking are not required. Anyone can easily build a structure by simply driving in the screws for wooden structures. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] <First Embodiment> Figure 1 is a structural drawing (plan view) of a wooden building according to a first embodiment of the present invention. The wooden building according to the first embodiment of the present invention is a single-story building. The structural drawing shown in Figure 1 is created on the premise that only square timber (wood) cut to the same predetermined length will be used as structural materials for the main structural parts such as the foundation, pillars, girders, joists, and ties that form the framework that supports the wooden building.

[0014] Figure 2 is a diagram showing the layout of the foundation of a wooden building in the first embodiment of the present invention. In the method for constructing a wooden building in the first embodiment of the present invention, the foundation 1, which is a structural material, is formed only from square timbers 10 cut to the same length of 3 m, as shown in Figure 2. The square timbers 10 are cedar pieces measuring 105 mm x 105 mm. As shown in Figure 2, a total of 15 square timbers 10, each 3 m long, are used for the foundation 1.

[0015] Figure 3 is a diagram showing the arrangement of columns in a wooden building in the first embodiment of the present invention. In the method for constructing a wooden building in the first embodiment of the present invention, columns 2, which are structural materials, are formed only from square timbers 10, the same as the foundation 1, as shown in Figure 3 by the cross marks in squares. As shown in Figure 3, a total of 69 square timbers 10, each 3 m long, are used for columns 2.

[0016] Fig. 4 is a diagram showing the arrangement of girders and ties of a wooden building in the first embodiment of the present invention. In the method for constructing a wooden building in the first embodiment of the present invention, as shown in Fig. 4, the structural members, girders 3 and ties 4, are formed only from square timbers 10, the same as the foundation 1. As shown in Fig. 4, a total of 29 square timbers 10, each 3 m long, are used for the girders 3 and ties 4.

[0017] That is, the structural materials used in the method for constructing a wooden building in the first embodiment of the present invention are only one type of timber 10, 105 mm x 105 mm square and 3 m long, a total of 113 pieces. These structural materials are joined together using wooden structural screws (not shown). At this time, it is desirable to screw the wooden structural screws diagonally into the timber 10. By screwing the wooden structural screws diagonally into the timber 10, the wooden structural screws enter diagonally into the annual rings of the timber 10, improving the pull-out strength. For example, Panelid S (product name) from Synegic Co., Ltd. can be used as the wooden structural screws.

[0018] Furthermore, by joining structural plywood as structural boards to the framework formed by these structural materials, a wooden building can be obtained using a new, simple and easy-to-construct wooden frame wall construction method. The structural plywood used is, for example, 12 mm x 1000 mm x 2000 mm. The structural plywood is fixed to the square timbers 10 at a specified pitch using coarse threads or the like.

[0019] In this way, in the wooden building of the first embodiment of the present invention, only square timbers 10 cut to the same predetermined length of 3 m are used as structural materials for the foundation 1, pillars 2, girders 3, ties 4, etc., so there is no need to consider which square timber to use in which location at the construction site, and anyone can easily build by simply using one type of square timber 10 in each location.

[0020] Furthermore, structural materials such as the base 1, pillars 2, girders 3, and ties 4 are joined together using structural wood screws, so advanced techniques such as tenoning, dovetailing, and hook-and-loop processing are not required, and anyone can easily build a structure by simply driving in structural wood screws.

[0021] In the method for constructing a wooden building according to the first embodiment of the present invention, pre-cutting and numbering are not required. Therefore, it is possible to stock timber 10 cut to the same 3-meter length, and these can also be used for wooden buildings constructed elsewhere. Furthermore, because only a minimum number of types of wood are required, construction can be carried out at low cost.

[0022] <Embodiment 2> The wooden building in the second embodiment of the present invention is a two-story apartment building. Figure 5 is a diagram showing the layout of the foundation of the wooden building in the second embodiment of the present invention. In the construction method for a wooden building in the second embodiment of the present invention, as shown in Figure 5, the foundation 5, which is a structural material, is formed only from the aforementioned square timbers 10 cut to the same length of 3 m. As shown in Figure 5, a total of 30 square timbers 10 with a length of 3 m are used for the foundation 5.

[0023] Figure 6 is a diagram showing the arrangement of first floor columns and first floor girders / joints of a wooden building in a second embodiment of the present invention. In the construction method for a wooden building in the second embodiment of the present invention, the first floor columns 6A, which are structural materials, are formed only from square timbers 10, the same as the foundation 5, as shown in Figure 6 by the cross marks in squares. As shown in Figure 6, a total of 160 square timbers 10, each 3 m long, are used for the first floor columns 6A.

[0024] In the wooden building construction method according to the second embodiment of the present invention, a total of 86 3-meter-long timbers 10 are used for the structural first floor girders 7A and ties 9A, as shown in Figure 6. In the wooden building construction method according to the second embodiment of the present invention, 28 2-meter-long timbers 11 cut to the same length are used as ties 8A. The timbers 11 are cedar pieces measuring 105 mm x 105 mm.

[0025] Figure 7 is a diagram showing the arrangement of second-floor columns of a wooden building in a second embodiment of the present invention. In the method for constructing a wooden building in the second embodiment of the present invention, as shown in Figure 7, second-floor columns 6B, which are structural materials, are formed only from square timbers 10, the same as the foundation 5. As shown in Figure 7, a total of 160 square timbers 10, each 3 m long, are used for the second-floor columns 6B.

[0026] Figure 8 is a diagram showing the arrangement of second floor columns and second floor girders and ties of a wooden building in the second embodiment of the present invention. In the construction method for a wooden building in the second embodiment of the present invention, as shown in Figure 8, the second floor girders 7B and ties 8B, which are structural materials, are formed only from the same square timbers 10 as the foundation 5. As shown in Figure 8, a total of 65 square timbers 10, each 3 m long, are used for the second floor girders 7B and ties 8B.

[0027] That is, the structural materials used in the wooden building construction method of the second embodiment of the present invention are only two types: 105 mm x 105 mm square timbers 10 with a length of 3 m and 2 m square timbers 11, for a total of 501 pieces of 3 m square timbers 10 and 28 pieces of 2 m square timbers 11. As in the first embodiment, the structural materials are joined together using wooden construction screws (not shown).

[0028] As described above, in the wooden building of the second embodiment of the present invention, only two types of structural materials are used for the foundation 5, first floor columns 6A, second floor columns 6B, first floor girders 7A, second floor girders 7B, ties 9A, 8A, 8B, etc.: square timbers 10 cut to the same predetermined length of 3 m and square timbers 11 cut to 2 m. Therefore, it is easy to know which square timber to use in which location at the construction site, and anyone can easily build.

[0029] In this embodiment, an example has been described in which only two types of timbers 10, 11 cut to the same predetermined length are used, but it is also possible to use 4m or 1m timbers as the same predetermined length. Furthermore, although the dimensions of the timbers can be changed as desired, to simplify construction, it is desirable to limit the number of types of timbers cut to the same predetermined length to four or less, more preferably three or less, and even more preferably two or less.
