Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method for a wooden building, which should be called a panel construction method using a double beam joint structure in a wooden building.

[0002]

2. Description of the Related Art Heretofore, in this type, the following has been done. 1. Japanese traditional wooden architecture was composed of columns and beams with a large cross section, and joints and joint structures were also rigidly joined. 2. The current general conventional method has been modernized and rationalized, and it is reinforced with a metal with a small cross section and becomes a pin joint.
The stilts bear the horizontal load. 3. The wood was also naturally dried and was constructed using sufficiently dried wood, but recently it has been artificially dried with a dryer. 4. The construction is supported by the skills of skilled carpenters. 5. Log logs are few due to lack of wood resources. 6. Since the steps of trees and beams have become smaller, the space between columns (span) has become smaller and more columns have been used.
Cutting, processing, and assembly are complicated. 7. There are various methods for the beam joint structure.

[0003]

The problems described in the prior art have the following problems. 1. It requires marking, cutting, processing and assembling by skilled carpenters with traditional Japanese techniques. 2. There is a wide variety of methods for joining horizontal materials such as beams, and the horizontal material is taken out from the pillars and continued, so the standard length is shortened. 3. Since it is a pin joint, a streak and a striking beam are required. 4. Although artificial drying is performed, it is difficult to dry because of the large cross section of the beam and only the surface is dried, so it is often a complaint after construction. 5. Due to lack of timber resources, there are problems such as soaring timber prices and being unable to remove thick materials. The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide a device capable of solving the above problems.

[0019]

Since the present invention is configured as described above, it has the following effects. [Effects of Double Beam Joint Structure] 1. No need for inking, cutting and processing by skilled carpenters with traditional Japanese techniques, and even relatively inexperienced people can easily perform cutting and processing. 2. Since the joint structure part of the double beam serves as a core joint on the column, it has the following effects. A. There is no need to bring out the horizontal material from the pillar and connect (connect) it as in the conventional case. That is, the standard length of the horizontal member is not wastefully shortened, and the length can be used as it is, so that the loss of the material is reduced. B. Since the size of the horizontal material can be set to the standard length,
Mass production of double beams is possible. C. The spacing between the columns can be between 2 (3,640 mm) and 2.5 (4,550 mm). That is, the pattern processing of the pillars is reduced, and further, the overall joint processing is also eliminated. As a result, panelization of the wall portion, floor portion, and roof portion can be promoted.

3. The joint part of the double beam can be connected simply by installing a backing plate. A. Since no skilled carpenter is needed on site, it is possible to solve the shortage of skilled carpenter, improve workability, and shorten the construction period. B. The strength is increased because it has a triple structure sandwiching the patch. That is, strong wood, reinforced plastic,
Bonding strength can be increased by using materials such as ceramics and iron. C. By shifting the holes in the caul plate, the beams can be pulled together when the lag screw is used for fastening. As a result, the joint portions come into close contact with each other, and the dimensional deviation at the joint portion is eliminated.

4. The base, the body difference, and the girder are 3.5 square members, and the double beam has the following effects. That is, 3
Even when high structural strength such as a story is required (a beam with a large cross section is required), it can be configured with double beams of 3.5 square beams. →
Material purchase management becomes easy and less expensive beam materials are required. 5. There is no restriction on the plan. That is, the structure of the framework can be determined by simply determining the positions of the columns, and extension / renovation can be easily performed.

[Effect of Paneling Floor Assembly] 1. The following effects are obtained due to the panel construction based on the floor construction of the conventional construction method. A. Panels with the same structure can be achieved on the first floor and the second floor. B. The panel size is 3 x 6 and it is easy to transport and install. C. Since the panel receiving material is used, it can be temporarily installed just by dropping it. 2. It can be used as a temporary scaffold by laying a control panel etc. by temporarily installing it by making the floor panel into panels, so it is possible to ensure the safety of erection work.

3. Since it is not necessary to process the floor assembly material (digging a joist), the work and assembly work is reduced and the construction period is shortened. 4. It is possible to prevent unevenness of the floor finish surface due to drying, warping, twisting, etc. of joists and differences in thickness. 5. No need for a skilled carpenter for flooring.

[Effect of Wall Panel] 1. Larger panels will be used between the columns, and panel manufacturing and erection work will be shortened. 2. The following effects can be achieved by using pillar-mounted panels. A. Pillars can be put in the required parts of the pillar (openings, joints of partition walls, etc.). B. If the column or beam is mounted above the opening, magsa can be included. C. Extension and renovation can be done easily as with the conventional method.

3. Since the bearing wall is made of structural plywood, there is no need for streaks, and the panel manufacturing effort is reduced. 4. The studs are 30 m / m in height and the underground P. By using B 12 m / m, it is possible to omit the building material underground furring, so panel processing and assembly costs are reduced. 5. It is possible to prevent kinks and breaks of uneven cloth on the finished wall surface due to drying, warping, twisting, etc. of the wall assembly, and differences in thickness. 6. No need for a skilled carpenter for wall assembly.

[Effect of roof panel] 1. The following effects are obtained due to the panel construction based on the conventional roof construction method. A. The panel is used in the field tarki part, which is lightweight and easy to stop because the mounting is flat. B. It is also possible to incorporate the base plywood into the panel in advance. C. Since the hut structure is the same as the conventional method, it can be assembled as usual. That is, on-site assembly is possible without using a crane or the like. 2. By using roof panels, curing in rainy weather can be done immediately and the entire building can be protected. 3. The roof panel makes it possible to reduce the amount of work at high places, which is safe and shortens the construction period. 4. After finishing the hut assembly (beams, bundles, purlins, hut reinforcements, etc.), the roof assembly is completed simply by fixing the panels, and the roof finishing material can be roofed. The safety of external work is good and the building itself can be protected quickly from rain.
