Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a structure in which concrete floor panels are stretched and attached to the floor of a building, such as the second or third floor.

[Background technology] Conventionally, as shown in Fig. 4, two girders are placed between one column.
A small beam 3 is constructed so as to be perpendicular to one of the large beams 2.
are constructed to constitute the frame of the building, outer wall panels 4 are arranged around the outer periphery of the building, the outer wall is assembled, and the outer wall panels 4 are fixed to the girders 2 with attachment materials 5.
On the floors of the second and third floors, a large number of concrete floor panels 6 are lined up over the entire surface, and the ends of adjacent concrete floor panels 6 are placed on the small beams 3. The concrete floor panels 6 that are adjacent to each other in the longitudinal direction of the small beams 3 are in contact with each other on their sides, and at the wall perpendicular to the small beams 3, the sides of the concrete floor panels 6 are placed above the large beams 2, and the small beams 3
The end of the concrete floor panel 6 is placed on the girder 2 near the wall parallel to the girder 2 . In the concrete floor panel 6, a notch 7 is provided along the entire length on the upper surface side of the side part, and a joint reinforcing bar 8 is installed in this notch 7.
is arranged, and a mounting plate 9 is erected between the end faces of the adjacent concrete floor panels 6 on the small beam 3.
The joint reinforcement 8 is inserted into the insertion hole 10 of the concrete floor panel 6, and the mortar 12 is filled so as to bury the joint reinforcement 8 in the side joint groove 11 between the sides of the concrete floor panel 6 formed by the notch 7. End joint groove 1 between end faces of adjacent concrete floor panels 6 via 3
3 is also filled with mortar 12. Also, at the wall where there is a large beam 2 perpendicular to the small beam 3, as shown in Figures 5 and 6, a spacer 14' is placed on the large beam 3 (the height of the upper surface of the large beam 2 is lower than that of the small beam 3). Therefore, a spacer 14' is interposed to absorb this level difference) The side part of the concrete floor panel 6 is placed,
A mounting plate 9 is erected on this spacer 14', and the joint reinforcement 8 inserted through the insertion hole 10 of the mounting plate 9 is positioned in the notch 7, and the girder 2
Above, mortar 12 is filled between the outer wall panel 4 and the side surface of the concrete floor panel 6 and in the notch 7. However, in such a conventional example, a large amount of mortar 12 is required to fix the side part of the concrete floor panel 6 on the large beam 2 on the wall perpendicular to the small beam 3.
The drawback was that it required a lot of work and was time-consuming to construct.

[Purpose of the invention] The present invention was made in view of the points mentioned above, and the purpose of the invention is to easily fix the side of a concrete floor panel near a wall with fixing brackets and to eliminate excess mortar. To provide a concrete floor panel mounting structure that does not require any work and is easy to construct.

[Disclosure of the invention] The mounting structure of the concrete floor panel of the present invention is to erect a large beam 2 along the wall of a building, erect a small beam 3 perpendicular to the large beam 2, and install a concrete floor panel on top of the small beam 3. The ends of the panels 6 are placed so that the end faces of the adjacent concrete floor panels 6 face each other via the small beams 3, and the side surfaces of the concrete floor panels 6 adjacent to each other in the longitudinal direction of the small beams 3 are made to face each other, and the concrete A joint reinforcing bar 8 is placed in a notch 7 provided along the entire length on the upper surface side of the floor panel 6, and an insertion hole for a mounting plate 9 is provided between the end faces of the concrete floor panel 6 adjacent to the small beam 3. 10
The joint reinforcing bars 8 are inserted into the grooves, and the side joint grooves 11 between the sides of the concrete floor panel 6 formed by the notches 7 are filled with mortar 12. filled with mortar 12, the girder 2 near the wall
A fixing fitting 15 is fixed on the top with a fixing device 16 such as a screw, and a locking hole 17 provided in the upper part of the fixing fitting 15 is fixed.
is fixed to a notch 7 in the side of a concrete floor panel 6 near a wall, and by configuring it as described above, the drawbacks of the conventional example are solved. In other words, fix the fixing fitting 15 on the girder 2 near the wall with a fixing device 16 such as a screw, and insert the locking hole 17 provided at the top of the fixing fitting 15 into the notch 7 on the side of the concrete floor panel 6 near the wall. By locking, the side part of the concrete floor panel 6 can be placed on the girder 2 near the wall by simply fixing the fixing metal fittings 15 on the girder 2 with the fasteners 16 and locking the locking holes 17 in the notches 7. It can be attached and can be easily constructed without requiring extra mortar 12 as in the conventional method.

The present invention will be explained in detail below using examples.

The structure of the building is the same as the conventional example, so the explanation will be omitted. Further, the concrete floor panel 6 is a concrete panel such as ALC, and has a notch 7 having a quarter circular cross section over the entire length on the upper surface side of the side part. The concrete floor panels 6 are also laid out in the same way as before and are attached in the same way as before, except for the walls that are perpendicular to the small beams 3, so the explanation will be omitted. A U-shaped spacer 14 with a lip in cross section is mounted on the large beam 2 that is perpendicular to the small beam 3.
The sides of the concrete floor panel 6 are placed on top. As shown in FIG. 3, the fixing metal fitting 15 is formed into a substantially L-shape, with an attachment hole 18 bored in the horizontal piece of the fixing metal fitting 15, and a fitting hole 18 along the notch 7 in the upper part of the vertical piece of the fixing metal fitting 15. A locking hole 17 is provided, and a through hole 19 is bored in the locking hole 17. When attaching the side part of the concrete floor panel 6 to the girder 2, as shown in FIGS. The fixing tool 16 such as a screw is inserted into the spacer 14 from the mounting hole 18 to fix the fixing tool 15, and the through hole 1
Starting from 9, nails 20 are driven into the concrete floor panel 6. Note that when the side of the concrete floor panel 6 is attached with the fixing fittings 15 in this way, a space is created between the side of the concrete floor panel 6 and the exterior wall panel 4, but the interior wall panel is placed on the indoor side of the exterior wall panel. Since the upper part of the empty space is covered, there is no problem when finishing the floor on the concrete floor panel 6.

[Effects of the invention] As described above, the present invention fixes a fixing fitting on a large beam near a wall using a fixing device such as a screw, and connects the locking part provided at the top of the fixing fitting to the side of a concrete floor panel near the wall. Since it has been secured to the notch, the side of the concrete floor panel can be attached to the main beam near the wall by simply securing the fixing bracket to the main beam with the fixing tool and locking the locking part to the notch. It is possible to eliminate waste of mortar without requiring extra mortar as in conventional methods, and it can be easily constructed.
