Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame construction method for a wooden house.

[0002]

2. Description of the Related Art In the conventional frame construction method for wooden houses,
A concave portion and a convex portion are provided on a joint surface of wooden timbers constituting a base, a pillar, a girder, a beam, and the like, and these are fitted to form a shaft assembly.

In recent years, the joint portion of the frame construction method has a simplified fitting portion shape, and in order to reinforce it,
Simple reinforcement hardware is used additionally.

[0004]

However, in the structure of the above-mentioned conventional example, when the force applied to the column, girder, beam, etc. is concentrated on the frame joint portion due to an earthquake or the like, the force is received by the fitting portion. Since the strength of the fitting part is reduced by the amount of scraping due to the formation of the concave and convex parts, the wooden square bar itself such as pillars, girders, beams, etc. does not have the strength itself and is destroyed. There is a problem that it ends up. In fact, when investigating the houses of the frame construction method that collapsed due to the earthquake, it was found that many joints of the frame were damaged.

In the framing method, recently, simple reinforcing metal fittings have been additionally used in the joint portion of the framing member, but these metal fittings are combined with the function of the fitting portion to form a wooden square bar of the joint portion. However, if the fitting part is damaged, the joint part will be destroyed even if there is a reinforcing metal object.

Further, in the case of constructing a wooden house by the conventional frame construction method, since concave and convex portions having a complicated structure are processed on the joint surface of the wooden lumber constituting the base, pillar, girder, beam, etc., There is a problem that the construction period becomes long, and there is a problem that a worker who has a technique for processing the concave portion and the convex portion is lacking.

The present invention solves the above problems and provides a base,
The strength of the joints of columns, girders, beams, etc. is great and the work is easy,
It is an object to provide a frame construction method for a wooden house that can shorten the construction period.

[0008]

In order to solve the above-mentioned problems, a frame construction method for a wooden house according to the first aspect of the present invention is made of a wooden timber such as a foundation, a pillar, a girder or a beam of the frame construction method for a wooden house. A fastening plate portion that covers at least the two welding side faces of at least two opposing side faces of each of the joined wooden timbers at the joining portion is integrally formed by bending and welding a metal plate, and the fastening plate portion has a predetermined shape. Arrange a metal joint with a number of bolt holes and screw holes, and fasten a wooden timber whose mutual joint surfaces are all flat joint surfaces by means of fastening members such as bolts, screws, and nails. It is characterized by doing.

In order to solve the above-mentioned problems, the frame construction method in the wooden house of the second invention of the present application is joined to the joint portion of the wooden square members such as the foundation, pillars, girders and beams of the frame construction method in the wooden house. Bending and welding of a metal plate with a joining plate part sandwiching both sides of a flat joining surface of a wooden timber and a fastening plate part covering at least two facing sides of the four joining sides of each joined wooden lumber And a joining metal article having a predetermined number of bolt holes and screw holes provided in the fastening plate portion, and a wooden square bar whose mutual joining surfaces are all flat joint surfaces. Is fastened with fastening members such as bolts, screws, and nails.

In order to solve the above-mentioned problems, the frame construction method for the wooden house of the first or second invention of the present application has a brim portion for fastening the ends of the braces when attaching the braces. It is preferable to use a joining hardware.

[0011]

The function of the frame construction in the wooden house of the first invention of the present application is as follows:
A wooden fitting such as a base, a pillar, a girder, or a beam is attached to each of the joining wood timbers with bolts, screws, bolts, screws, etc. Fasten with a fastening member such as a nail to form a joint,
In addition, since the respective joint surfaces of the wooden lumbers constituting the joint portion are flat joint surfaces, the foundations, pillars and girders by the fastening plate portions on the two opposite side faces of the wooden lumbers such as the base, the pillar, the girder and the beam. ,
The holding power for wooden timber such as beams is not only large, but also has the effect of wrapping the wooden timber such as the base, columns, girders, and beams at the joints to reinforce its strength, and also the foundation, pillars, and joints at the joints, Since there are no weak points due to the formation of recesses or protrusions in wooden lumber itself such as girders and beams, columns,
Even if the force applied to the girder, beam, etc. is concentrated in the frame joint, the strength of the joint that combines the strength of the joint metal and the strength of the wooden timber such as the base, column, girder, and beam is sufficient to withstand it. Has strong strength. Of course, by increasing the number of fastening plates,
If the fastening plate portions are provided on the three side surfaces of the wooden square members such as the girder and the beam, the strength is further improved.

In the frame construction method for the wooden house of the second invention of the present application, since the joining metal object has the joining plate portion which is sandwiched on both sides by the flat joining surface of the joined wooden timber in addition to the constitution of the first invention of the present application, The strength of the joint metal is improved by this joint plate portion, and the action of wrapping the wooden squares such as the base, pillars, girders, and beams in the joint portion to reinforce the strength is also improved. Further improved than the invention.

Further, in the frame construction method in the wooden house of the first or second invention of the present application, since the joint surface of the wooden square members such as the base, the pillar, the girder and the beam is a flat surface, the construction is easier than the conventional construction method. This shortens the construction period and eliminates the need for skilled workers. In addition, when it comes to mass-produced products, the unit price of the joining metal will be less than the labor cost reduction due to the shortening of the construction period, and the overall cost can be reduced.

Further, in the frame construction method in the wooden house of the first or second invention of the present application, a brim portion for fastening the ends of the braces to the joint metal is added and the braces are attached, whereby the strength of the frame is improved. Is greatly improved.
