DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure of a building and, more particularly, to a floor structure effective for a steel house floor.

[0002]

2. Description of the Related Art FIG. 13 is a perspective view of a standard detail of a steel-frame flooring structure issued by a steel club. In the drawing, reference numeral 1 denotes a concrete foundation in which anchor bolts 2 are buried, and a rim track 5 made of a channel steel is attached to the outdoor side of the upper surface thereof via a clip angle 3 fixed to the anchor bolts 2. I have. Numeral 6 is a lip channel steel, one end of which is a joist inserted between the flanges at right angles to the flange on the indoor side of the rim track 5 and a stiffener 7 is fixed between the rim track 5 and the joist 6. The web is reinforced.

Reference numeral 8 denotes a plywood for floor, which is placed on the rim truck 5 and the joist 6, and is screwed to a flange to form a floor assembly. Reference numeral 9a denotes a channel frame steel, which is a lower frame of a wall frame (hereinafter referred to as a lower frame) mounted on the plywood 8 for floor, and a stud 10 at a position corresponding to the flange of the joist 6.
a, a hole-down hardware (not shown) is attached as needed, and an upper frame of a wall frame (9b in FIG. 14, hereinafter referred to as an upper frame) is attached to the upper end of the stud 10a. Then, the frame constituted by the upper frame 9b, the stud 10a, and the lower frame 9a is positioned on the flange of the joist 6, and the rim truck 5
And the flange of the joist 6 are screwed together and integrally joined to form a frame-shaped frame. In addition, 11 is a surface material stuck on the outdoor side of a wall frame.

FIG. 14 shows the floor structure of the upper floor (the second floor) of FIG. 13, in which 9b is made of channel steel and studs 1 on the first floor.
The upper frame attached to the upper end of the upper frame 9a has a flange of the rim track 5 screwed to the outside of the web of the upper frame 9b. The other structure is the same as the case of the first floor (FIG. 12).

[0005] When a load-bearing wall is formed by braces up and down via a floor set on the second floor, as shown in FIG. 15, a rim truck 5, a joist 6, and a stiffener 7 are placed on an upper frame 9b on the first floor. And a second floor set composed of floor plywood 8 is screwed and fixed, and the second floor wall is positioned so that the second floor stud 10b is located on the flange of the joist 6 via the floor plywood 8 on the joist 6. Place the frame and stud 1
0b to the upper frame 9 on the first floor from the hole-down hardware 12
The bolt 13 is inserted through b, fixed with a nut, and integrally joined.

FIG. 16 shows an example of a conventional second-floor partition wall. Two rim tracks 5a and 5b are arranged back to back by abutting a web, and screwed to the web of the upper frame 9b. . Then, the joists 6a, 6b are fitted between the flanges of the rim tracks 5a, 5b, respectively, and the stiffeners 7a, 7b are fixed between the rim tracks 5a, 5b and the joists 6a, 6b to reinforce both webs. It was done.

[0007]

The stiffener is basically installed directly below the upper stud for the purpose of stress transmission. However, conventionally, when the joist 6 is fixed to the rim track 5, the stiffener is aligned with the module. The studs 10a,
A joist 6 is attached directly below 10b (hereinafter sometimes simply referred to as 10), a web of the joist 6 and a stiffener 7 are joined, and a web of the stud 10 and a web of the joist 6 are arranged on the same plane. Therefore, the stud 10 and the stiffener 7 are not aligned with each other, which is not preferable in structure.

The arrangement of the joist 6 is based on the stud 1
Because it is affected by the arrangement and orientation of the zeros, not only is it time-consuming to maintain the integrity of the framework between the wall frame and the floor, but it is also necessary to give instructions in the drawing, and it is troublesome to check on site and work efficiency Decrease. Further, the fitting of the connecting portions of the wall frames on the upper and lower floors is as shown in FIG.
In the case of the partition wall portion, the length of the joist 6 may differ depending on the orientation of the rim track 5 depending on its orientation even if the layout is the same, because the web of the rim track 5 is arranged on one side of the wall frame. For this reason, detailed instructions using drawings are indispensable, and the amount of information in the drawings and the number of types of members increase, so that management and work are increased.

[0009] The fitting shown in FIG. 16 is also provided, but it is difficult to connect the load-bearing walls by the brace on the upper and lower floors by the hole-down hardware and the bolt as shown in FIG. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a simple structure, good workability, easy connection between upper and lower floors, and a floor structure of a building having a preferable stress transmission mechanism. The purpose is to obtain.
