FIG. 8 is a plan view, FIG. 8 is a side cross-sectional view showing a connection state by a room corner fitting B, FIG. 9 is a drawing showing a procedure for joining floor concrete boards 1, 1 by a butt joining fitting A, and FIG. Drawing which shows the connecting work procedure by the corner part metal fitting B, FIG. 11 is a back view of the part of the beam part metal fitting 3 and the tightening bolt 4, FIG. 12 is the same beam part metal fitting 3
And FIG. 13 is a front view of the beam insertion fitting 3 and the tightening bolt 4, FIG. 14 is a plan view of the tightening plate 5, and FIG. 15 is a side view of the tightening plate 5.

FIG. 1 is a bird's-eye view showing a state in which the floor concrete board 1 is placed and fixed on the floor portion on the second floor. Beams 2 supporting the floor of the second floor are arranged in parallel. On the flat surface portion 2a of the beam 2, concrete floor boards 1 are placed in a butt shape from the left and right. With the floor concrete boards 1 and 1 butted against each other, a tightening bolt 4 is provided in a small space formed between them.
, And the tightening plate 5 is placed on the upper surface of the floor concrete board 1.1.
The beam insertion fitting 3 is disposed on the lower surface of the.

The beam insertion fitting 3 is required to be fixed not only on the lower surface of the floor concrete board 1.1 but also between the floor concrete board 1.1 and the beam 2. Therefore, the beam portion fitting 3 is provided with a fitting U-shaped portion 3a that is laterally fitted to the flat surface portion 2a of the beam 2. By fitting the fitting U-shaped portion 3a into the flat portion 2a formed on the upper portion of the beam 2 from the side, the butt joint metal fitting A and the end portion of the floor concrete board 1.1 are brought into contact with each other. The tangential engagement prevents the floor concrete board 1 from moving in the longitudinal direction. The floor concrete board 1 is prevented from moving in the lateral direction by the floor concrete board 1 being spread.

The floor concrete board 1 is constructed as shown in FIG. The floor concrete board 1 is made of soft foam concrete (ALC).
Then, above and below the end portion in the longitudinal direction, the upper connection concave portion 1a,
The lower connecting concave portion 1b is configured. The upper connection recess 1a
And the lower connection concave portion 1b are formed in different shapes.

In FIG. 3, a butt joint metal fitting A is shown. The butt joint metal fitting A includes a beam insertion metal fitting 3, a tightening bolt 4, and a tightening plate 5. The tightening bolt 4 is welded and fixed to the beam portion fitting 3 to be integrated. Then, as described above, the beam insertion fitting 3 is provided with the fitting U-shaped portion 3a which is inserted into the plane portion 2a of the beam 2 from the side surface. Also tightening plate 5
Is a reinforcing rib 5a for improving its tightening strength.
Two are projected. Further, a fastening nut 8 is screwed onto the fastening bolt 4 to fix the floor concrete board 1.

In FIG. 4, the structure of the room corner coupling fitting B is disclosed. The room corner joining fitting B is composed of a concrete board for floor 1 and a beam holding fitting 6 that comes into contact with the flat portion 2a from below, a tightening bolt 7 and a round washer. A fastening nut 10 is screwed onto the fastening bolt 7 for fastening. The beam reinforcing member 6 also has a strength reinforcing rib 6a protruding therefrom.

In FIGS. 5 and 6, the fastening state by the butt joint metal fitting A is shown. Beam 2 is usually
It is composed of "D" shaped steel and has a flat surface 2
a is constituted. The fitting U-shaped portion 3a of the beam insertion fitting 3 is fitted to the flat surface 2a. Further, a joint gap is formed between the floor concrete boards 1 and 1 in order to facilitate the assembly, and conventionally, mortar was poured into this portion, but in the present invention, the joint is formed. The tightening bolt 4 is passed through the gap.

7 and 8 show the state of connection by the room corner connection fitting B. As shown in FIG. In the wall portion of the house, a wall frame 9 is erected on the beam 2. Therefore,
Only the end of the floor concrete board 1 from one side is placed on the flat portion 2a of the portion, and the floor concrete board 1 is placed and fixed on the half of the flat portion 2a. There is a need to. Therefore, since the tightening bolt 7 cannot be passed through utilizing the joint gap between the floor concrete boards 1 and 1, the insertion hole for the tightening bolt 7 is drilled in the floor concrete board 1. Then, the beam clamping member 6 having the bent portion 6b is brought into contact with the lower side of the end of the floor concrete board 1,
A fastening nut 10 is screwed into a fastening bolt 7 fitted in the hole of the beam holding member 6.

FIG. 9 illustrates a procedure for connecting and fixing the floor concrete boards 1 and 1 by the butt joint metal fitting A. The concrete board for floor 1 is placed on the flat surface portion 2a of the beam 2 in order from the end of the room. Then, in the end portion of the floor concrete board 1, the portion of the fitting U-shaped portion 3a of the beam insertion fitting 3 is fitted to the flat surface portion 2a on the side where the floor concrete board 1 is not yet mounted. To do. Then, the tightening bolt 4 is projected upward, and the other new concrete board for floor 1 is placed on the flat surface portion 2a. At a position where both ends are in a butted state with the tightening bolt 4 interposed therebetween, the tightening plate 5 is inserted and tightened by the tightening nut 8.

FIG. 10 illustrates a fixing and fastening procedure using the room corner coupling fitting B. First, the end portion of the floor concrete board 1 is placed on the flat surface portion 2a so as to abut against the wall shaft assembly 9 with a small gap (however, before the wall shaft assembly 9 is constructed, the floor concrete material is placed). Board 1 may be installed first). Next, a hole is opened in the upper connection concave portion 1a of the floor concrete board 1 with a drill. Tightening bolts 7 are inserted from below or above the holes to penetrate the beam-portion holding metal fittings 6 and the holes. Then, the fastening nut 10 is screwed and fastened to either the upward or downward fastening bolt 7. 7 and 8 show the state in which the tightening bolt 7 is inserted from above and the tightening nut 10 is screwed.

11, 12, and 13 show the portions of the beam insertion metal fitting 3 and the tightening bolt 4 which constitute the butt joint metal fitting A. In the beam insertion fitting 3, a notch 3b is formed in the fitting U-shaped portion 3a so that the fastening bolt 4 can be easily welded and fixed. Further, the fitting U-shaped portion 3a is formed with an introduction inclined surface 3c so as to be easily fitted to the flat surface portion 2a.

In FIGS. 15 and 16, the tightening plate 5 is shown. The tightening plate 5 is provided with a strength reinforcing rib 5a and a bolt hole 5b through which the tightening bolt 4 penetrates is opened.

[0019]

As described above, the present invention has the following advantages. Since it is configured as in claim 1, the mortar work required in the conventional fixing work of the house floor board is eliminated, and the curing period is eliminated,
By shortening the setup time and eliminating the staggering of floors caused by mortar, it was possible to prevent the construction site from becoming soiled by mortar work.

According to the second aspect of the present invention, the room corner connecting fitting B allows the room corners to be connected and fixed without using mortar even at the part facing the wall shaft assembly 9. It became possible, and all the work of installing the board for the house floor could be done by dry work, which does not require mortar.
