Description

The present invention relates to a structural material composed of a combination of a wooden structural member and a metal.

In wooden construction, CLT (Cross) is used for structural materials such as columns and beams.
In the case of wooden structural members made only of wood such as Laminated Timber) or laminated wood, there are fragile aspects such as distortion and compression as wood, so long spans and large cross sections are taken into consideration. It is difficult to form the structural material of.
Therefore, it is known that a wooden structural member and a metal are combined to form a long and large cross-section structural material having high rigidity. For example, a structural material composed of a combination of laminated wood and a steel material such as H-shaped steel is known (see Non-Patent Document 1).

However, in the structural material that combines the laminated wood and the steel material described above, for example, when forming a beam having a long span, it is necessary to increase the beam sill, so that the steel material must also be a steel material having a high stake. It doesn't become.
That is, in the structural material in which the above-mentioned laminated wood and the steel material are combined, a recess for incorporating the steel material must be formed inside the laminated wood forming the surface side of the structural material such as a beam or a column. Processing) cost is high.
In addition, in the structural material that combines the above-mentioned laminated material and steel material, when forming a beam, various cross-sectional dimensions are obtained according to the required beam length and cross-sectional dimensions of the beam (beam width, beam length). A steel material is required, and when a column is formed, a steel material having various cross-sectional dimensions corresponding to the required column length and cross-sectional dimension of the column is required, so that the component cost is high.
That is, there is a problem that the cost of the structural material which is a combination of the laminated wood and the steel material described above becomes high.
The present invention provides an inexpensive structural material having high rigidity by combining a wooden structural member and a metal.

In contact with each other, the vertical plate is installed so as to be sandwiched between the facing surface of one wooden structural member and the facing surface of the other wooden structural member, and the lower end of the vertical plate of one T-section steel and the other T. Since a gap is provided between the vertical plate and the lower end of the shaped steel, structural materials with various cross-sectional dimensions can be formed by using T-shaped steel with a constant cross-sectional dimension and changing the spacing. At the same time, the wooden structural member of the structural material is constrained from the outside by one T-shaped steel and the other T-shaped steel, so that a more rigid structural material can be provided.

The plate material is installed in a state of being sandwiched between the facing surfaces of the wooden structural members, and a space is provided between the lower end of the vertical plate of the T-shaped steel and the plate material. By using a constant T-shaped steel and changing the interval, it becomes possible to form structural materials with various cross-sectional dimensions, and the amount of T-shaped steel used can be reduced. It will be possible to provide it at a low price.
Further, since the horizontal plate of the T-shaped steel is fixed to one wooden structural member and the other wooden structural member by a fixing member, one wooden structural member, the T-shaped steel, and the other wooden structural member are used. And can be more firmly integrated, and the rigidity of the structural material can be further improved.
