Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a wooden building drum used as a structural horizontal member in a wooden building such as a wooden house.
[0002]
[Problems to be solved by the invention]
In recent years, members processed as sizing materials of a predetermined standard, such as artificial drying materials and laminated materials, are frequently used as structural materials such as columns and beams in the wooden frame construction method. Also, instead of “cutting” work by craftsmen's manual processing, “pre-cut” processing by machining at the factory has become the mainstream, and the construction method is rationalized and the period is shortened.
[0003]
On the other hand, due to nature-oriented, health-oriented, etc., the use of traditional taiko beams as a structural horizontal member and making it look like this is increasing. . However, since taiko-ri is a raw tree, it has drawbacks such as a large twist and expansion / contraction rate, and has a low value as a structural material. Moreover, since the dimensions and shapes are various, they cannot be processed by a general precut processing machine, and the craftsmen have insufficient skills and experience to process them, so that their use has not been achieved. Furthermore, in order to construct a floor on a drum beam, the workability is extremely inferior.
[0004]
The present invention proposes a drum drum with a new structure, and aims to increase the strength against twisting and expansion and contraction, which are disadvantages of natural materials, and to enable the same handling as sizing materials without requiring technology or experience. It is what. And it aims at promoting the utilization of a drum beam by making precut processing possible, improving its workability, and rationalizing the construction method.
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the wooden beam for wooden construction of the present invention is formed as shown in FIG. 1, and the side portion of the square member 3 is fitted and joined to the groove 2 formed along the longitudinal direction on the upper surface. The square bar 3 protrudes to form a ridge along the longitudinal direction on the upper surface. It is preferable that the square member 3 is formed of a laminated material that is unlikely to be distorted or twisted.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be specifically described below with reference to the drawings.
The drawing shows an embodiment of the present invention. The drum beam 1 is formed by cutting off the left and right side surfaces of a log and sawing both edge edges L of the lower surface, and forming grooves 2 along the longitudinal direction on the upper surface. By fitting and joining the side portions of the square members 3 to the grooves 2 and projecting the square members 3, convex strips along the longitudinal direction are formed on the upper surface of the drum beam 1. In this way, the square rod 3 is integrated with the natural drum drum 1, and the square rod 3 is made of a square or flat rod having a size suitable for the size of the drum drum 1, and has a precise dimensional accuracy and a madness. Glulam that is less likely to twist is suitable.
[0007]
The drum beam formed in this manner is stable in the dimensions of the four facets of the fore edge, and is formed with two flat surfaces (the upper surface of the square member 3 and the side surface of the drum beam 1) that serve as the processing reference surface of the processing machine line. Therefore, this can be incorporated into the processing machine line and can be automatically processed by precut in the same manner as the sizing material. Moreover, by constructing this drum beam with the upper surface of the square member 3 as a reference, it is possible to construct a floor without making a leveling structure.
[0008]
【The invention's effect】
As described above, the taiko beam for wooden construction according to the present invention is a structure in which the taiko beam 1 of raw wood is reinforced with the square member 3 to improve the strength against torsion and expansion / contraction peculiar to natural materials. It is possible to obtain suitable and stable performance.
[0009]
In addition, the drum beam of the present invention can be pre-cut, its workability is remarkably improved, and it can be handled in the same way as sizing material without requiring technology or experience. Can be promoted.
[0010]
In addition, since it has a simple structure in which the square bar 3 is joined to the drum beam 1, it can be manufactured at a low cost and can be developed in various standard dimensions according to the application. By using the drum beam of the present invention, a natural material can be obtained. It is possible to easily express a design rich in texture.
