Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to a method for reinforcing buildings.

[Conventional technology]

Conventionally, flat plates have been used as tensile reinforcing materials for wooden buildings and reinforcing rods for steel-framed buildings.

[Problem that the invention sought to solve] In order to use a flat plate, the pillars and studs had to be cut out by the thickness of the plate. For this reason, there was a drawback that processing was time-consuming and the strength of the column was reduced.

Ideally, braces should be used in a criss-cross pattern, but because the slope is so thick, there is no suitable method for dealing with intersection points, and braces on only one side are often used.

In steel structures, round bars are often used as braces, but they require auxiliary parts such as end fixing fittings, turnbuckles, and cylindrical connecting fittings, and construction costs such as welding and tightening work are high.

[Means to solve the problem]

The object of the present invention is to solve the conventional problems by using a steel strip having continuous holes in the longitudinal direction as a tensile reinforcing material.

[Effect]

Steel strips can be produced in large quantities by methods such as cold rolling, and the drilling process can be made continuous, so they are inexpensive.

In addition, it has high tensile strength and is thin, so it is easy to intersect, long lengths are available, and if holes are made continuously, nailing and bolting are easy. . .

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

A flat steel strip 1 as shown in FIG. 1 was provided with continuous round holes 2 at regular intervals in one to several rows in the longitudinal direction of the central part thereof to serve as a reinforcing material.

The steel strip should preferably have a yield point strength of 2500 kg/cri or more, which has increased tensile strength by increasing carbon content, adding Mn-3i, etc., cold rolling, or quenching. . Its thickness is 0.5~5N, width is 1
A long length of 0 to 200 mm and wound into three coils is used. Round holes are for passing nails and bolts, and their straight lines range from several to ten.

Usage Example 1 In a wooden frame structure, as shown in Fig. 2, braces are installed in a cross pattern between the pillars 4 on the wall.

The ends are fixed with nails 5 through appropriate round holes. Tighten the bolts 6 and nuts 1) at the intersections of the steel strips. The parts where it intersects with the studs 41 are fixed by nailing.

As shown in the third ryI, it is also effective to use it as a horizontal brace. Wrap it around pillar 4 and nail it, and with the steel band upright, install it under the floor or in the ceiling. A mounting bracket may be attached to the column and the steel strip may be stretched on a rough floor. It is available in long lengths and does not take up as much space as flat plates, so it can be installed in places where it was previously difficult to add braces.

Usage example 2 In a lightweight steel structure, as shown in Figure 4, the wall surface 7
It is used as a criss-cross brace along the .

A screw hole is cut in the steel frame 8, and the steel band 1 is directly fixed with bolts 6.

Even in a 2 x 4 wooden structure, it is possible to strengthen the structure by reinforcing it with steel bands along the wall, as shown in Figure 4, to increase its earthquake resistance.

Other Usage Examples FIG. 5 shows an example in which it is used as a brace on a panel 10 with crosspieces 9. The steel strip I is nailed diagonally to the back surface of the surface plate 1).

It can also be used for tensile reinforcement of steel structures, and instead of reinforcing bars,
It can also be used in conjunction with reinforcing bars to reinforce concrete. (Refer to the patent application filed on March 14, 1986, title of the invention: "Method for reinforcing concrete.") [Effects] Since this invention is constructed as described above, it has the following advantages. There is.

■ Steel strips are most suitable for mass-producing high-strength materials at low cost using methods such as cold rolling.

■ The 6m band can be mass-produced at low cost because the hole drilling process is suitable for continuous processing.

■ Since the steel strip can be wound into a coil, long lengths can be supplied.

■ Since the holes are continuous, nails and bolts can be passed through and fixed at any location.

■ Because it is thin, it can be attached directly to a pillar or wall without making a notch.

■ Because it is thin, it is easy to cross the steel strips, and it is also possible to connect them through holes.
