Abstract

PROBLEM TO BE SOLVED: To maintain rigidity and an external appearance characterisitice of wood by forming a cross-shaped steel frame long size material by continuously arranging four thin iron plates in a radial shape, and respectively fixing square timbers to respective installing spaces formed between the adjacent thin iron plates. SOLUTION: Four thin iron plates 11 are continuously arranged in a radial shape by using its lengthwise directional edges as root and trunk parts, and a cross-sectional cross-shaped steel frame long size material 10 is formed. Thin square timbers 12 respectively composed of wood are arranged in four installing spaces A formed of the adjacent thin iron plates 11, and are fixed to the steel frame long size material 10, and a column body 1 is formed. A notch space B to which the thin square timbers 12 are not fixed is arranged in the middle of the column body 1. A beam body is fixed to the notch space B of the column body 1 by bolts and nuts or the like through a bracket. Therefore, rigidity can be maintained by the steel frame long size material 10, and an external appearance characteristic and hygroscopicity of wood can be maintained by the thin square timbers 12.

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a novel composite building material.

[0002]

2. Description of the Related Art Conventionally, wood, iron, etc. have been known as building materials. Wood has excellent hygroscopicity and appearance, while iron has excellent rigidity. In a conventional building, it was determined which building material to use in consideration of these characteristics.

[0003]

However, such conventional building materials have their own advantages as described above, but on the other hand, wood has poor rigidity and iron materials absorb moisture. However, it has the disadvantage that the iron material and the appearance cannot be satisfied for those who desire a wooden house.

An object of the present invention is to eliminate such inconvenience.

[0005]

In order to achieve the above-mentioned object, a composite building material according to the present invention is provided with a steel frame long member having a cross-shaped cross section and four square members, and the steel frame long member is provided. Connect four thin iron plates radially with their longitudinal edges as the roots and form an installation space between these adjacent thin iron plates, and arrange the four timbers in this installation space. Since it was fixed and fixed, and the overall shape was formed into a square pole,

The long steel member having a cross-shaped cross section can maintain the rigidity, and the four square members arranged around the steel member can maintain the appearance and hygroscopicity of the wood.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view of a building structure using the composite building material according to the present invention, FIG. 2 is a perspective view of a first embodiment of the composite building material according to the present invention, and FIG. 3 is the present invention. 4 is a perspective view of a second embodiment of the composite building material according to the present invention, FIG. 4 is a perspective view of a third embodiment of the composite building material according to the present invention, and FIG. 5 is a perspective view of the fourth embodiment of the composite building material according to the present invention. It is a figure.

In FIG. 1, C is a structure, and this structure C is composed of one column body 1 and four beam bodies 2. The column body 1 and the beam bodies 2, 2, 3, 3 correspond to the composite building material according to the present invention.

First, FIG. 2 shows the columnar body 1, and the columnar body 1 has a steel elongated member 10 as an axis. This long steel frame material 10 comprises four thin iron plates 11, 11, ... Connected in a cross shape in cross section, and the same thin iron plates 11, 11 are provided between adjacent thin iron plates 11, 11.
One installation space A, A, ... Is formed. . The long iron frame material 10 may be formed by integrally connecting the thin iron plates 11 and 11 by welding.

.. are fine rectangular members, which are arranged in the installation spaces A, A, ... of the steel elongated member 10 and fixed to the steel elongated member 10 by means of bolts and nuts. At this time, the entire shape is formed in a quadrangular prism shape as shown in the figure. In addition, when fixing the steel long member 10 to the fine rectangular members 12, 12, ..., It is not limited to the bolt and nut means, and includes all the conventional fixing means.

B, B, ... are notched spaces, and the pillar 1
Is formed in the middle of. The cutout spaces B, B, ... Are only the long steel frame members 10, and the rectangular members 12, 12 ,. The beam body 2 is connected to the cutout spaces B, B, ... As shown in FIG.

Next, FIG. 3 shows the first beam body 2, and the first beam body 2 uses the steel elongated member 10 as an axis, like the column body 1. This long steel frame material 10 is exactly the same as the case of the pillar 1. In this beam body 2, the steel frame long material 10 projects in one direction. Then, in the projecting portion of the long steel frame member 10, the pair of horizontal thin iron plates 111, 111 further project to form a gap S therebetween. As shown in FIG. 1, this gap S
When the first beam body 2 is connected to the front column body 1, it is fitted onto the thin iron plate 11 of the notch B in the column body 1. At this time, the leading edge of the vertical thin iron plates 112, 112 of the first beam body 2 is in contact with the side edge of the thin iron plate 11 of the cutout portion B in the columnar body 1. The state in which the first beam body 2 is connected to the column body 2 is as shown in FIG.
It is sandwiched between 5,5 and fixed with bolts and nuts. It should be noted that the brackets 5 and 5 can be fixed by welding without using them.

Next, FIG. 4 shows the second beam body 3, and the second beam body 3 has the steel frame long member 10 as an axis, like the column body 1. This steel long member 10 is exactly the same as the case of the column body 1 or the first beam body 2. In this second beam body 3, the steel frame long material 10 projects in one direction. And, in the projecting portion of the steel frame long member 10, thin iron plates continuously provided vertically
Four L plates 6,6, ... are stacked and fixed along 11,11. The L plates 6, 6, ... Are further projected than the projecting portion of the steel long member 10. A cross gap T is formed between these L plates 6, 6, .... Then, as shown in FIG. 1, when the second beam body 2 is connected to the front column body 1 (the first beam body 2 is already connected), the cross gap T is formed in the column body 1. The thin iron plate 11 and the horizontal thin iron plate 111 of the first beam body 2 are externally fitted to a cross-shaped continuous portion. The second beam body 2 is connected to the column body 2 and the first beam body 2 with
It is fixed with nuts. It should be noted that it is also possible to fix it by welding without using bolts and nuts.

As shown in FIG. 5, fine rectangular members 15, 15, ... Having a triangular cross section (right-angled isosceles triangle) are used.
It is a quadrangular prism-shaped composite building material such as the pillar 1.

Industrial Applicability The composite building material according to the present invention comprises a steel frame long member having a cross-shaped cross section and four square members, and the steel frame long member is composed of four thin iron plates at the edges in the longitudinal direction. Since the installation space is formed between these adjacent thin iron plates while being radially connected to each other as a root portion, and the four square members are arranged and fixed in this installation space, the overall shape is formed into a square column shape,

The long steel member having a cross-shaped cross section can maintain the rigidity, and the four square members arranged around the steel member can maintain the appearance and hygroscopicity of the wood.

Therefore, by using this composite building material, it is possible to easily construct a structure on the exterior wooden structure having excellent rigidity.
