DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall frame comprising a base made of a channel steel mounted on a foundation, upper and lower frame members made of channel steel, and vertical frame members made of lip channel steel. And a steel house comprising a base and a floor plywood attached to a joist made of channel steel, wherein the wall frame is fixed to the base via the floor plywood, and more particularly to a base structure thereof. It is.

[0002]

2. Description of the Related Art Recently, steel houses have been constructed in place of wooden houses. This steel house, especially its base structure, is composed of a base installed on a foundation, an upper frame, a lower frame (track) of about 1 mm thick channel steel, and a vertical frame material (stud) of 1 mm thickness. A wall frame constructed by incorporating front and rear lip channel steels into a frame shape, and the wall frame is erected and fixed on the base via a plywood and a spacer for floor mounted on the base and the joist. It is.

FIG. 11 is a perspective view of a standard detail of a base structure of a steel house issued by the Steel Club, and FIG. 12 is a schematic longitudinal sectional view of FIG. In both figures, reference numeral 1 denotes a concrete foundation on which anchor bolts 2 are erected, and a base 3 made of channel steel is attached to the outdoor side of the upper surface thereof via a clip angle 4 fixed to the anchor bolts 2. ing. 5 is made of lip channel steel,
On the indoor side of the base 3, a joist is mounted between the flanges at right angles to the flange, and a web reinforcing member 6 is fixed between the base 3 and the joist 5 to reinforce both webs.

[0004] Reference numeral 7 denotes a floor plywood placed on a joist 5 and screwed thereto, and 8 denotes a base 3 in contact with an outdoor end of the floor plywood 7.
The spacer is screwed on top. 9 is a track (lower frame) made of a channel steel, and 10 is a stud made of a lip channel steel and erected on the track 9.
A truck (upper frame) (not shown) is attached to the upper end of the “0”, and these form a frame-like wall frame 17.

In order to assemble the base structure as described above, first, the clip angle 4 is fixed to the anchor bolt 2 of the base 1, and the base 3 is screwed to the clip angle 4 to fix the base 3 to the base 1. . Then, web reinforcement 6
A floor frame is constructed by attaching a joist 5 through the above, and a floor plywood 7 is placed thereon, and a spacer 8 is placed on the base 3 and fixed with screws. Next, the wall frame 17 previously assembled by inserting the studs 10 into the upper and lower tracks 9 and screwing it is placed on the floor plywood 7 and the spacer 8, and the track 9 of the wall frame 17 is put on the floor plywood. 7 and spacer 8
Screw on the base 3 and the joist 5 via. Then, the face material 11 is screwed to the outdoor side of the base 3 and the wall frame 17 and the indoor side of the wall frame 17.

[0006]

In the base structure of the conventional steel house constructed as described above, the base 3 is attached via the clip angle 4, and in particular,
In the 2 × 4 size wall, the anchor bolt 2 cannot be provided on the center line of the track 9 in the width direction. For this reason, existing hole down hardware cannot be installed,
The stress transmission in the lower part of the stud 10 at the side end of the wall frame 17 is not properly performed.

Further, since the flange width of the base 3 is narrow, only the spacer 8 is fixed on the flange, and the floor plywood 7 cannot be fixed. Therefore, depending on construction conditions, as shown in FIG. The end of the plywood 7 may hang down. Furthermore, since the joist 5 is mounted inside the flange of the base 3, there is a step between the spacer 7 fixed on the flange of the base 3 and the floor plywood 7 fixed on the joist 5. It is formed. For this reason, it becomes difficult to mount the wall frame 17 vertically and accurately.

In order to solve such a problem, a substantially H-shaped base in which channel steels constituting the base 3 are joined back to back may be used, but the anchor bolt 2 is still passed through the center of the wall frame 17. In addition, in order to fix the base 3 to the foundation 1, it is generally necessary to use two anchor bolts.
This leads to higher costs. If the base is fixed with one anchor bolt, the construction is complicated and the structure becomes complicated.

In order to secure the strength, rigidity or durability of the base, an H-shaped steel may be used as the base. However, when the wall frame 17 is temporarily fixed to the base, the flange of the H-shaped steel is thick. For this reason, there are various problems such as the inability to use a normal tapping screw.

[0010] The present invention has been made to solve the above-mentioned problems, and an anchor bolt can be provided at the center in the width direction of a track constituting a wall frame.
The purpose of the present invention is to obtain a steel house base structure in which floor plywood and a spacer can be installed on the same plane, and a steel house base structure in which the channel steel forming the base is not likely to deform or buckle. It was done.

[0011]
