Description

TECHNICAL FIELD The present invention relates to a building composite member.

(Prior Art) Conventionally, as a building composite member, there is one in which an iron plate 91 is fixed to the outer surface of a prismatic base material 90 as a reinforcing material with bolts and nuts 92, as shown in FIG.

(Problems to be Solved by the Invention) The conventional building composite member described above is suitable when used in a location that cannot be seen from the outside, but when used in a location that is seen from the outside, the iron plate 91 is the base. Since it is fixed to the outer surface of the material 90, there is a problem of impairing the appearance of the building, especially the interior.

An object of the present invention is to solve the above problems of conventional members and to provide a building composite member that can obtain a desired strength without impairing the appearance of the building.

(Means for Solving the Problems) In order to achieve the above object, the building composite member according to claim (1) comprises a tubular or semi-cylindrical base material having an inner wall surface and an outer wall surface, and A building composite member comprising a reinforcing material bonded and fixed to the inner wall surface of a base material, wherein the base material is formed by laminating thin single plates in the same direction.

The building composite member according to claim (2) is characterized in that, in the building composite member according to claim (1), the reinforcing material is bonded and fixed only to a site having a required strength in the building composite member. And

Note that, here, “a portion having a large required strength” means a portion having a relatively large required strength as compared with other portions of the building composite member.

The building composite member according to claim (3) is the building composite member according to claim (1), in which both the base material and the reinforcing material are tubular, and the reinforcing material is press-fitted into the hollow portion of the equipment. It is characterized by being.

(Operation effect) Since the building composite member of the present invention has the above-mentioned configuration, it has the following operation effects.

According to the building composite member of claim (1), since the base material is tubular or semi-cylindrical, the weight can be reduced and desired strength can be obtained, and the base material is hollow due to its inner wall surface. Since the part or the recess is formed and the reinforcing material is bonded and fixed to the inner wall surface of the part or the recess, the reinforcing material is accommodated in the hollow part or the recess.

Therefore, according to this building composite member, a desired strength can be obtained by the reinforcing material without impairing the building appearance even when it is used in a location visible from the outside.

Further, the base material can be formed simply by laminating thin veneers, and since the laminating directions of the thin veneers are the same direction, it can be formed by laminating the thin veneers in order. As a result, the building composite member can be easily manufactured. Further, even when the peripheral wall portions of the base material are separately produced and then joined, the lamination surfaces of the thin veneers are in the same direction over all the peripheral wall portions, and therefore the treatment of the joint surface is unnecessary. Therefore, the manufacturing can be easily performed, and as a result, the building composite member can be easily manufactured.

Moreover, since the base material can be formed by sequentially laminating and fixing thin veneers that have been formed in a predetermined shape in the same direction in sequence, it is possible to easily form a substrate whose axis is non-linear.

According to the building composite member of claim (2), in the building composite member of claim (1), the reinforcing material is bonded and fixed only to a portion of the building composite member having a large necessary strength. Therefore, it is possible to reduce the weight because there is no reinforcing material in other parts.

According to the building composite member of claim (3), in the building composite member of claim (1), both the base material and the reinforcing material are tubular, and the reinforcing material is provided in the hollow portion of the base material. Since it can be formed by press fitting, it can be manufactured more easily.

Moreover, since the base material and the reinforcing material are both tubular,
It is possible to increase the strength while reducing the weight.
