Description

[Detailed description of the invention] This invention relates to a floor panel mounting structure.

Conventional floor panels are installed as shown in FIG. That is, a connecting plate 2 is welded and fixed to the inner surface of a lattice beam 1 installed between pillars, a large support fitting 3 is bolted to this connection plate 2, and a wooden main puller 4 is placed on the large support fitting 3. The frame is fixed, and a floor panel 5 is placed on the wooden stand 4 and fixed with nails 6. As described above, since the installation of the floor panel 6 requires the installation work 4, there is a problem in that the installation is complicated.

Therefore, the purpose of this invention is to provide a floor panel mounting structure that can be easily constructed.

An embodiment of this invention will be explained with reference to FIGS. 1 to 11. In other words, this floor panel mounting structure has four corners at square corners, as shown in Figure 2.
A book pole 7 is erected, and 4
A bridge is constructed by aligning the external lattice beams 8 at the same height, and a pair of external lattice beams 8, 8 facing each other are constructed.
An internal lattice beam 9 is bridged between the central positions of the internal lattice beams 9 and the upper surface of the internal lattice beam 9 is placed at a lower position than the upper surface of the external lattice beam 8. Note that the above-mentioned rectangle includes a square and a rectangle. In addition, panel holders (details will be described later) are installed on the inside corners of the external lattice beams 8, 8 and on the opposing inside surfaces of a pair of external lattice beams 8, 8 parallel to the internal lattice beams 9. The upper surface is set at approximately the same height as the upper surface of the internal lattice beam 9 and spaced apart, and the two floor panels 10, 10 are mounted and fixed in parallel on these panel brackets and the internal lattice beam 9. .

The detailed structure of each joint is as follows. First, the structure of the joint A in FIG. 2 is as shown in FIG. End plate 12

The upper surface 9a is arranged at a lower position than the upper surface 8c of the external lattice beam 8.

The structure of the joint B in Fig. 2 is similar to that in Figs. 4 and 5.
As shown in the figure. That is, the external lattice beams 8 have end plates 1 welded to their end faces.
5 to the two adjacent sides of pillar 7, bolt 16, nut 1
Fix by 7. In this case, the nut 17 is welded and fixed to the inner surface of the column 7 in advance. Furthermore, a panel holder 19 is attached to the inner end of the external lattice beam 8 via a hat-shaped plate 18. This hat-shaped plate 18 has fitting slits 18a formed at its upper and lower ends.
Insert the flanges of the upper chord member 8a and lower chord member 8b into the outer lattice beam 8 and attach them to the external lattice beam 8. Furthermore, the panel holder 19 has an L shape made up of a vertical piece 19a and a horizontal piece 19b.
While reinforcing the shaped piece with ribs 19c, the vertical piece 19
A and a horizontal piece 19b are provided with bolt insertion holes 19d, and the vertical piece 19a is placed in contact with both outer flange pieces 18b of the hat-shaped plate 18, and the bolt 20 and nut 2 are inserted.
Connect by 1. In this case, the height of the horizontal piece 19b is set to be approximately the same as the height of the upper surface 9a of the internal lattice beam 9 (FIG. 3). The floor panel 10 is constructed by mounting a lower corner portion of a panel outer frame 10a formed of a channel steel frame on a horizontal piece 19b of a panel receiving fitting 19, and connecting the panel frame 10a with bolts 22 and nuts 23.

The structure of the joint C in FIG. 2 is similar to that in FIGS. 6 and 7.
As shown in the figure. That is, the connecting plate 24 is welded and fixed to the inner surface of the external lattice beam 8,
A panel holder 25 is fixed to this connection plate 24. This panel holder 25 also has an L-shaped piece consisting of a vertical piece 25a and a horizontal piece 25b, reinforced with ribs 25c, and bolt insertion holes 25d are bored in the vertical piece 25a and horizontal piece 25b to connect the vertical piece 25a. It is connected along the plate 24 with bolts 26 and nuts 27. In this case, the height of the horizontal piece 25b of the panel holder 25 is the same as that of the panel holder 19 shown in FIG.
Align it to the same height as the horizontal piece 19b. floor panel 10
The panel outer frame 10a is mounted on the horizontal piece 25b of the panel holder 25 and connected with bolts 28 and nuts 29. In addition, in FIG. 7, 10b is a panel middle frame formed of channel steel.

The structure of the joint D in FIG. 2 is as shown in FIG. 8. That is, the panel holder 30 is bolted to the connection plate 31 welded to the external lattice beam 8. In this case, the panel holder 30 is the seventh
It has the same structure as the panel holder 25 shown in the figure, and is attached to the external lattice beam 8 in the same manner as the panel holder 25. On the horizontal piece 30a of this panel holder 30, the adjacent corner parts of two floor panels 10, 10 arranged in parallel are mounted on the right half and the left half, respectively, and the respective panel outer frames 10a, 10a are mounted. The corner portion is connected to the horizontal piece 30a by bolts and nuts through the bolt insertion hole 30b.

The structure of the joint E in FIG. 2 is as shown in FIG. 9. That is, the panel outer frame 10a of the floor panel 10 is orthogonally mounted on the internal lattice beam 9 via the spacer 32, and the hook part 33 of the hook bolt 33 is
The floor panel 10 is connected to the internal lattice beam 9 by hooking the hook bolt 33 onto the upper chord member 9b, passing the threaded portion 33b of the hook bolt 33 through the panel outer frame 10a, and fastening the nut 34. In this case, the height of the top surface of the spacer 32 is set to be the same as the height of the top surface of the horizontal piece 19b of the panel holder 19 shown in FIG.

The structure of the joint F in FIG. 2 is as shown in FIGS. 10 and 11. That is, the connecting plate 35 is welded and fixed between the upper chord member 9b and the lower chord member 9c (FIG. 3) of the internal lattice beam 9, and the panel holder 36 is attached to the connecting plate 35. This panel holder 36 is an L-shaped piece consisting of a vertical piece 36a and a horizontal piece 36b. Bolt insertion holes (not shown) are bored in both pieces 36a and 36b, and the vertical piece 36a is aligned with the connecting plate 35 and bolted 37, connected by a nut 38. In this case, the height of the horizontal piece 36b is set to the fourth
It is set at the same height as the horizontal piece 19b of the panel holder 19 shown in the figure. The floor panel 10 is mounted with its panel middle frame 10b orthogonally mounted on the horizontal piece 36b of the panel holder 36, and connected with bolts 39 and nuts 40.

In this way, the floor panel 10 is connected to the external lattice beam 8.
In other words, it is bolted directly to each panel bracket 19, 25, 36 connected to the internal lattice beam 9, so that
Construction can be simplified because the main draw 4) shown in the figure can be omitted altogether. In addition, since a large floor panel with a metal panel frame is used as the floor panel 10, the rigidity of the panel frames 10a and 10b is lower than that of the conventional wooden Ohiki.
It is much larger than the one shown in Figure 1, and the sound insulation performance of the upper and lower floors can also be improved.

As described above, the floor panel mounting structure of this invention consists of four pillars arranged at square corner positions, four external beams bridging between adjacent pillars, and a pair of facing external beams located at the center. An inner beam with a bridge in between and a top surface lower than the top surface of the outer beam, and a pair of outer beams that are parallel to the inside corner of the outer beam and the opposite inner surfaces of the pair of outer beams are parallel to each other. Panel holders are arranged at intervals in the direction and their upper surfaces are aligned at the same height as the upper surface of the inner beam, and panel holders are arranged in parallel along the inner beam with their sides abutted, and the center of the lower surface of each is aligned with the inner beam. Since it is equipped with a plurality of floor panels that are mounted and fixed on a rack and each of which has its four corners on the lower surface mounted and fixed on the panel receiving metal fittings, it has the advantage that it can be easily constructed.
