Abstract

PURPOSE:To enhance workability by molding a mounting section whose cross section is recessed on both sides of a flat square-shaped column pipe based on a press molding process or a roll molding process and boring a mounting long hole on the recessed mounting section. CONSTITUTION:A mounting section 1 whose cross section is recessed is formed on both sides of a metal-made flat square-shaped column pipe 2 based on a press molding process or a roll molding process. A mounting long hole 3 is bored on this recessed mounting part 1 in cross section where a specified height wall section 4 is formed there. What is more, a recessed auxiliary member whose length is adjustable in a longitudinal direction is fitted into the cross sectional recessed mounting part 1 in such a fashion that it may move freely. It is, therefore, possible to enhance workability without damaging mechanical strength.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prismatic building material for use, for example, in braces for prefabricated houses, house sidings, and reinforcing materials for construction.

[0002]

2. Description of the Related Art As a frame structure technology for a conventional structure, for example, a house bracing, there is disclosed, for example, Japanese Patent Laid-Open No. 54-1.
As disclosed in Japanese Patent No. 42816, a fixed-angle L-shaped metal fitting having a plate provided on one side of two side faces at a corner between corners between a base and a base, or a cross member such as a base and a body difference. There has been one in which a bracing metal fitting such as a rod-shaped turnbuckle is attached between the L-shaped fittings facing each other so as to be adjustable. As described above, as a means for attaching a brace such as a turnbuckle to the L-shaped metal fitting, a hook for locking a turnbuckle is provided on the mounting plate.

[0003]

By the way, according to the framing method using the conventional brace fittings such as the turnbuckle disclosed in the above publication, the hook for locking the turnbuckle is simply attached to the mounting plate. Since it is provided, it is not possible to completely prevent the deformation due to the lateral force.

[0004]

The prismatic building material of the present invention has the object of solving the above-mentioned problems, and is formed by press-molding or roll-molding concave cross-section mounting portions on both sides of a metal flat prismatic pipe. However, it is characterized in that mounting long holes are respectively provided in these mounting portions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 to FIG. 5 show a first prismatic building material according to the present invention.
1 is a plan view of the prismatic building material of the present invention, FIG. 2 is a front view thereof, FIG. 3 is a side view thereof, and FIG. 4 is a sectional view taken along line AA in FIG. 5 is a sectional view taken along the line BB.

In each of the drawings, reference numeral 1 denotes mounting portions having a concave cross-section formed on both sides of a metal flat prismatic pipe 2 by press molding or roll molding. The mounting elongated holes 3 are formed through the mounting portions 1 having a concave cross section. The mounting long hole 3 is also used as a water draining hole. Walls 4 having a predetermined height are formed on both sides of the recessed cross-section mounting portion 1 in order to obtain mechanical strength.

That is, by forming such a wall portion 4, the mounting portion 1 having a concave sectional shape is extremely strong against twisting, expanding, compressing, and bending stress.

When the prismatic building material according to the present invention is constructed as described above, the workability is improved and the bolts, nuts, etc. are improved without impairing the mechanical strength of the prismatic pipe itself, unlike the one obtained by crushing a round pipe. Unlike the round pipe, the mounting of the end portion with the concave-section-shaped mounting portion 1 has extremely good workability.

FIG. 6 is a perspective view showing a second embodiment of the prismatic building material according to the present invention. In the second embodiment shown in this figure, an auxiliary member 5 having a concave sectional shape whose length can be freely adjusted in the longitudinal direction is provided so as to be fitted and movable with respect to the concave sectional mounting portion 1. Further, the auxiliary member 5 is provided with a mounting long hole 6 which is aligned with the mounting long hole 3 which is provided through the concave section mounting portion 1. Fastening members such as bolts are inserted into the mounting long holes 3 and 6.

FIG. 7 is a perspective view showing a third embodiment of the prismatic building material according to the present invention, in which an appropriate rib 7 is formed in a portion of the mounting portion 1 having the concave sectional shape which requires strength. FIG. 8 is a perspective view showing a fourth embodiment of the prismatic building material according to the present invention, in which appropriate ribs 7 are formed in the upward and downward spaces 8 and 9 where strength is required. . By forming the appropriate ribs 7 in this manner, the prismatic building material of the present invention has a stronger structure.

9 (A) and 9 (B) are sectional views showing a fifth embodiment of a prismatic building material according to the present invention. This prismatic building material is used as a pair of bracing fittings 10 and 11. It is a thing. One of the brace members 10 is shown in FIG.
As shown in (A), the above-mentioned metal flat prismatic pipe 2 is provided with the concave section mounting portions 1 on both sides by press molding or roll molding. An upward space 8 is formed in the center by press molding or roll molding. As shown in FIG. 9 (B), the other brace fitting 11 has mounting portions 1 each having a concave cross-section formed by press molding or roll molding on both sides of the flat metal prismatic pipe 2 made of metal. A downward space portion 9 is formed by press molding or roll molding at substantially the center of the flat-shaped prismatic pipe 2.

FIG. 10 is a side view showing an embodiment of a wall floor framing method in which the pair of brace fittings 10 and 11 shown in FIGS. 9A and 9B are used, for example, by tacking each other. . That is, for example, the installation plates 14 provided at the corners of the horizontal member 12 and the pillar 13 such as the base and the body difference.
In addition, the pair of brace fittings 10 and 11 are hooked on each other and fixed by the mounting portion 1 having the concave sectional shape.

The pair of brace fittings 10 and 11 include:
Since the space portions 8 and 9 are respectively provided at the portions corresponding to the central intersection portion, the pair of bracing metal fittings 10 and 11 in the form of hooks engage each other in the space portions 8 and 9 at the same time. It becomes a flat surface state and can prevent distortion due to lateral force.

EFFECTS OF THE INVENTION According to the prismatic building material of the present invention, mounting portions having concave sectional shapes are formed on both sides of a metal flat prismatic pipe by press molding or roll molding, and the mounting holes are provided in the concave sectional mounting portions. Since it has been pierced respectively, it does not impair the mechanical strength of the prismatic pipe itself, it has better workability unlike the crushed round pipe, and it also has a concave cross-section mounting part with bolts, nuts, etc. Unlike the case of the round pipe, the mounting is sure and firm, the workability is extremely improved, and there are various practical effects such as cost reduction. In addition, the attachment long hole has an effect that it is also used as a water drain hole.
