JPH0949290A - High tension steel wire bracing - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily fit bracings at the most effective angle without hindrance against a framework at various planes of structure of a wooden building, by using bracings provided with rectangular fixing steel plate tools with needle holes at both ends of a high tension steel wire. SOLUTION: Fixing tools 2 made of a rectangular steel plate with a plurality of needle holes are pushed into both ends of one or more high tension steel wires 1 to form high tension steel wire bracings 2 and 1 fastening or welding them. The fixing tools 2 at both ends of the bracings are fixed to the side faces of a wooden members like a sill 3, a girth 4, an eaves girder 5, a pipe column 6 with nails or wooden screws. Since the intersection 10 of the bracings is bulky two times as much as the diameter of the high tension steel wire 1, it is adjusted so as not to be positioned on a stud 12 or a pipe column 6 or it is fitted to only one direction on one plane of structure. The bracing can be used as well for reinforcing of a non-bearing wall like a narrow wall 8 or a spandrel wall 9 or reinforcing of a horizontal plane of structure like a roof or a floor.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to braces used in wooden construction. The brace can be used anywhere because it is easy to install and is thin and not bulky. For example, in place of conventional braces, used alone or in combination with them for load bearing walls, as well as for stiffening small walls, waist walls, etc., and for stiffening horizontal structures such as roofs and floors. It will improve the proof stress of the building.

[0002]

2. Description of the Related Art Conventionally, the braces used in wooden construction include thick braces, thin braces, round steel braces and steel strip braces.

[0003]

The conventional braces used in wooden construction are slightly cumbersome to construct because they are inserted diagonally inside the quadrilateral frame. It may be subject to the above restrictions. For example, studs attached to the inside of the same quadrilateral framing must have notches at the portions that intersect the braces, or braces cannot be placed across the pipe columns. As a result, due to the lack of understanding by craftsmen, the braces are not performing their performance properly at many sites without proper construction. Many experts have pointed out that one of the causes of the damage to buildings caused by the Great Hanshin Earthquake in January 1995 is the lack of bracing for wooden houses. As is well known. In order to improve such a situation, it is necessary to provide a brace that is easier to use and can be used anywhere.

The problem to be solved by the present invention lies in what kind of means should be taken to solve such a problem.

[0005]

In order to solve such a problem, the present invention proposes the following brace. First of all, in order to be able to be used for all construction surfaces of a building, it must be bulky and not interfere with other steel materials, so the material has a diameter of 2.3 m.
A high-tensile steel wire of about m, for example, a piano wire was used.

Next, in order to facilitate the mounting work,
The fasteners can be fixed with nails or wood screws from the side of wooden parts such as the base, columns, body differences, and eaves girders. As the stopper, a steel plate having a thickness of about 2.3 mm in which several nail holes were drilled was used, and both ends of the high-strength steel wire were screwed, tightened, welded, or the like.

[0007]

As shown in FIG. 1, the braces are inserted diagonally into the construction surface of the building to resist the pulling force against the horizontal load received by the building. Since it is not always necessary to put them in a diagonal line of a quadrangle, it is possible to put as many lines as necessary according to the situation. The installation is extremely simple because it is only fixed with nails or wood screws from the side.

Further, since the pipe pillar can be mounted without being damaged, it can be inserted at an angle close to 45 degrees, which is most effective as a bracing.

Further, as shown in FIG. 1, it can be inserted into a small wall or a waist wall. Even if the required wall ratio under the Building Standards Act was calculated with the horizontal load bearing ratio of non-bearing walls including small walls and waist walls being calculated as 1/3, these non-bearing walls also make sense. It can be said that it is extremely effective as a means of earthquake resistance and wind resistance to improve the rigidity by adding the.

An embodiment will be described with reference to the drawings. FIG. 1 is an explanatory view showing an example of use in which a high-strength steel wire reinforcement according to the present invention is used for an outer peripheral wall. B is a high-strength steel wire bar, which is a high-strength steel wire 1 to which stoppers 2 made of strip-shaped steel plates are attached at both ends. The fastener 2 has a plurality of nail holes formed therein, and is fixed to the base 3, the body difference 4, the eaves girder 5, the pipe pillar 6 and the like with nails 7 or wood screws. Small wall 8 and waist wall 9
It can be easily attached to non-bearing walls such as.
At the bracing crossover 10, the bulk is 2 times the diameter of the high-strength steel wire.
Since it will be double, that is, about 5 mm, the mounting position is adjusted so that the bracing crossing portion 10 is not located on the stud or the pipe pillar so as not to hinder the exterior base material or the exterior material being stretched from above. did. In addition, in order to prevent the braces from crossing, they may be attached to one structure surface in only one direction without being attached to the tray. In the figure, 11 is a bearing wall, 12 is a stud, and 13
Is a cloth foundation.

FIG. 2 is an explanatory view showing one embodiment of a method of mounting the stopper, in which the stopper 2 is mounted on the end portion of the high-strength steel wire 1. A plurality of nail holes 14 were opened in a strip-shaped steel plate having a thickness of 2.3 mm, and the end portion of a high-strength steel wire 1 having a diameter of 2.3 mm was welded thereto. Reference numeral 15 is a welded portion.

FIG. 3 is an explanatory view showing another embodiment in which the stopper 2 is attached to the end of the high-strength steel wire 1, and the method of attaching the stopper is shown. A plurality of nail holes 14 are made in a 2.3 mm thick steel plate processed into strips, and two 2.3 mm diameter holes are formed in this.
The end portion of the high-strength steel wire 1 was welded. Reference numeral 15 is a welded portion.

FIG. 4 is an explanatory view showing another embodiment in which the stopper 2 is attached to the end of the high-strength steel wire 1, and the method of attaching the stopper is shown. A steel plate having a thickness of 2.3 mm was bent and welded as shown in the figure to form a hole 16 through which the high-strength steel wire 1 was inserted, and a plurality of nail holes 14 were formed. 1 thread on end of hole 16
The high-strength steel wire 1 that was cut at No. 7 was passed through, and it was stopped with a hexagon nut 18 through a washer though not visible in the figure.

FIG. 5 is an explanatory view showing a state in which the stopper 2 is joined to the base 3. The protrusions 19 were fixed to the inside of the construction surface with the nails 7 so that the protrusions 19 did not hinder the stretching of the exterior base material or the exterior material. Reference numeral 1 is a high-strength steel wire, which was fixed with a hexagon nut 18 via a washer 20.

[0015]

Since the present invention is constructed as described above, it has the following effects.

The construction is extremely easy because it is only necessary to fix it with nails or wood screws from the side of the construction surface.

The high-strength steel wire braces do not interfere with the frame forming the structural surface, so that they are either bearing walls or non-bearing walls, small walls, waist walls, etc. You can put it in any part.

Further, by increasing the number of inserted pieces,
The bearing capacity of the wall can be increased in any way.
