Abstract

PROBLEM TO BE SOLVED: To give a strength about five times stronger than wooden members to this composite member, by embedding iron members such as iron plates or iron rods in the whole length, so as not to be exposed at the sides. SOLUTION: Two sheets of iron plates 2, 2 are embedded in the upper and lower parts of a columnar wooden member with a rectangular section, in the whole length, so as not to be exposed to the sides. Four iron rods can be vertically and laterally embedded in the columnar wooden member 1 with a rectangular section so as not to be exposed at the sides. There are various embedding ways of iron plates or iron rods. In this case, the wooden member 1 is divided and iron plates or rods are arranged therein and integrally connected together with an adhesive. Accordingly, this method can give a strength about five times stronger than a wooden member. The composite member is appropriate for a long span beam or column and a firm connection is easily realized. And since one can handle it in the same feeling with wooden members, it does not bring any incongruous feeling to workers and further, the same workability with wooden buildings and the strength equal to steel channels can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building material used for "beams", columns and the like of a wooden building.

[0002]

2. Description of the Related Art Conventionally, it has been generally practiced to construct a building of a wooden building through a reinforcing metal fitting or a joint metal fitting between structures.

[0003]

However, serious defects such as insufficient frictional force between the connecting surfaces of wood and metal, cracking of the wood by tightening the bolt, and loosening of the bolt by shrinkage of the wood occur. There was fear.

[0004] In wooden construction, it is desirable to connect timber structural members without using metal fittings as in the case of an old construction method, but it is impossible in terms of workability, cost, and strength. there were.

[0005]

Means for Solving the Problems Applicants have arrived at the present invention as a result of intensive studies to solve the above-mentioned problems, and the present invention is based on the toughness of steel materials (iron plates, reinforcing bars, etc.). Developed a composite structural member that combines the goodness of wood with the gentleness of wood, which gives it about five times the strength of wood, and gives the construction company a sense of incongruity by using wood. It can be used as usual without connecting, and by providing a connecting part at the end of the structure, the connection with other members is simple and robust, and it is possible to use the conventional connection hardware It is intended to provide a building material which is several steps in comparison.

FIG. 5 is a perspective view of a column-shaped composite construction member in which a steel material (2) is buried intermittently over the entire length, and FIGS. 2) is a perspective view of a column-shaped composite construction member in which an iron plate or a steel material (2) having a U-shaped cross section is joined and integrated on opposite side surfaces.

FIGS. 8 to 10 show a third embodiment of the present invention, in which the columnar member according to the present invention is used in a horizontal direction such as tension and the like. FIG. 3 is a perspective view showing a bar arrangement specification and partially embedded in a longitudinal direction of a member. 11 to 18 are diagrams showing an embodiment according to claim 4, wherein only the steel material (2) is extended at the end of the construction member to form a connection portion (2-1).
Reference numeral (3) in the drawing indicates a bolt hole or a screw hole at the time of connection with another member.

[0008]

FIG. 1 shows a construction member in which two iron plates (2) and (2) are buried and interposed over the entire length of a pillar-shaped timber (1) having a rectangular cross section over the entire length. In addition, the dark-eye shape in the present invention indicates a shape in which the embedded steel material (2) is not exposed on the side. FIG. 2 shows a construction member in which a single iron plate (2) is buried in the center of a pillar-shaped timber (1) having a rectangular cross section over the entire length.

FIGS. 3 and 4 are views showing an embodiment in which a reinforcing bar (2) is inserted and inserted in place of the iron plate. FIG. 3 shows four reinforcing bars vertically and horizontally for a columnar timber (1) having a rectangular cross section. FIG. 4 shows a columnar timber (1) in which two rebars (2) are embedded.

Various methods are conceivable for the embedding of the iron plate or the reinforcing bar (2). One example is shown in FIGS.
As shown in (1), the wood (1) is divided, the iron plate (2) is arranged, and joined integrally with an adhesive. FIG. 19 is a cross-sectional view of a columnar body, where wood is (1-a), (1-b), (1-c), (1).
-D), and the metal plate (2) is arranged at the center and bonded and molded. FIG. 20 shows that wood is divided into two parts (1-a) and (1-a).
b) Then, the iron plate (2) is sandwiched and bonded and formed.

FIG. 5 and FIG. 6 show a pillar-shaped timber having a rectangular cross section (1).
This is a construction material in which an iron plate (2) is integrally bonded to opposing sides. FIG. 7 is an embodiment diagram of a construction material in which a steel cross-section (2) having a U-shaped cross section is bonded.

FIGS. 8, 9 and 10 show the case where the columnar member is used in a horizontal direction such as tension, etc., with reference to FIGS. In the case of FIG. 8, the upper iron plate (2) is embedded at both ends and the lower iron plate (2) is buried in the center in the case of FIG. It retains the same strength as the implanted one. Therefore, the same effect is obtained in the case of the reinforcing bar of FIG. 9 and the case of the iron plate (1) of FIG.

FIG. 11 and FIG. 12 show members in which a joint (2-1) is formed by extending the end of a steel material (2) embedded in wood (1), and FIG. This is a member in which a joint is formed. In the figure, a member having a joint portion provided at one end of the member is shown. However, it is needless to say that the member may be provided at both ends as necessary. Symbol (3) in the figure
Are bolt holes and screw holes for convenient connection with other members.

FIG. 14 and FIG. 15 show modifications of the extended connection portion. FIG. 14 shows a T-shape, and FIG. 15 shows an embodiment in which a thread (2-2) is engraved on a reinforcing bar. .

FIGS. 16 and 17 show a joint (2-1) formed by bonding an iron plate (2) to opposing sides of a columnar timber (1) having a rectangular cross section and extending an integrated iron plate end. In the drawings, reference numeral (3) indicates a bolt hole or a screw hole at the time of joining. Further, FIG. 18 shows a steel sheet having a U-shaped cross section bonded in place of the iron plate. In the figure, only one of the steel sheets (2) is brought out to join the joint (2-1).
Is formed, but it is of course possible to provide both as needed.

Although not shown, the steel material (2) may be replaced with an H-shaped steel or the like, if necessary, and may be a stronger construction material. In some cases, the steel material (2) may be replaced with an aluminum material, a glass fiber plate or a steel material. By using an inorganic fiber plate such as a carbon fiber plate, a lightweight and strong construction member can be obtained.

[0017]

The composite construction member of the present invention can be made as a composite member of wood and steel, so that it can have a strength about five times that of wood, and can be used as a long span beam or column. Suitable for conventional wooden building components that are easy to connect, robust and easy to work with, as well as wood, so that workers do not have a sense of incongruity, workability equivalent to wooden buildings and strength comparable to steel groove Has an outstanding action and effect that is not seen.
