2. Description of the Related Art In the frame wall construction method, a construction method using a lightweight section steel having a thickness of about 1 mm as a frame material has been widely used in Japan and overseas.
As shown in Japanese Patent No. 0193, a channel steel with a lip (C-shaped steel) is used as a frame material. In this case, as a method for binding the vertical frame members, as shown in FIGS. 5 and 6, a method of bolting with a pull-in hardware is employed as in the conventional wooden frame construction method and the like. Examples of the attracting hardware are shown in the catalog as commercial products. These are shown in FIGS. 5 and 6 in which the band plate 21 of the attracting hardware 2 is pulled from the opening between the lips of the lip-shaped channel steel 1. Channel steel with lip (C-shaped steel)
And is bolted to the inside of the web.

[0003]

However, in the case of fixing the lip-shaped channel steel 1 which is a vertical member using the pull-in hardware 2 as described above, the width of the pull-in hardware 2 is limited to the opening between the lips of the channel steel. , And must be smaller than that. In that case, the width of the base plate 22, which is the attachment portion of the pulling hardware 2 to the foundation, naturally becomes narrow. As an example, when the web width of the lip-shaped channel steel 1 is 89 mm and the lip widths on both sides are 12 mm, the width of the attracting metal is less than 65 mm. Under such conditions, the anchor bolt 4 having a diameter of 22 mm
In order to fix the base plate 22 of the pulling hardware 2 to the foundation by using a nut, it is necessary to use a nut 8 and a washer in order to fasten the anchor bolt 4. 8 and the washer interfere with the reinforcing plate 24 of the pull-in hardware, so that tightening of the nut 8 becomes practically impossible.

[0004] In consideration of the construction accuracy of the anchor bolt 4,
Although a certain tolerance is recognized in the bolt hole 23 provided in the base plate 22, the value is 3 m in the above example.
m, and it is generally difficult to maintain such accuracy. If the value exceeds this value, there is a great problem in construction such as the need to re-mount the anchor bolt 4. In order to solve such a problem, it is conceivable to attach the pulling hardware 2 to the outer surface of the web of the lip-shaped grooved steel 1. However, in general, the vertical frame material that requires the pulling hardware 2 is used to prevent earthquakes and strong winds. As shown in FIG. 1 or FIG. 5, two channel steels are often used together on the web surface, and it is necessary to attach a pull-in hardware 2 to the inner side of the web of the channel steel 1 with lip.

An object of the present invention is to solve the above-mentioned problems of the prior art, so that the width of the pull-in hardware 2 can be made sufficiently large. It is an object of the present invention to propose a fixing structure capable of fixing a lip-shaped channel steel without requiring a number of steps.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a structure in which the width of a base plate, which is a fixing portion of an anchor bolt 4, can be widened without being restricted by the interval between lips of a channel steel having lips. Specifically, the vertical member of the lip-shaped channel steel is attached to the inner side web of the lip-shaped channel steel and fixed to the foundation via a strip plate portion and an anchor bolt which can be fixed. In the fixing structure of the vertical member fixed by the attracting hardware consisting of the base plate to be fixed, the vertical member of the channel steel with a lip has a lip notch near the fixing portion, and the attracting hardware has a width equal to its width. Is made wider than the opening between the lips of the lip-shaped channel steel, and the strip plate portion of the pull-in hardware is provided on the lip-shaped channel steel through a lip notch portion to form an inner surface of the channel steel. Side wa It is intended to be fixed to. Furthermore, the lip notch provided in the lip-shaped channel steel is provided in a minimum range where the reinforcing plate provided in the corner portion of the band plate and the base plate of the drawing hardware does not interfere with the lip of the lip-shaped channel steel. is there.
