Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a technique for attaching concrete floor panels so that they do not shake in the horizontal direction.

[Background Art 1 Conventionally, when installing a concrete floor panel, the end of the floor panel 1 is placed on the beam 2 as shown in FIGS. 7 and 18, and the adjacent floor panels are placed on the beam 2. Steps 16 are formed at the side ends of the panel 1, and reinforcing bars 18 are arranged within the four sections 17 formed by the adjacent steps 16, and the reinforcing bars 18 are welded to the beams 2 in holes 19. Rebar insertion hole 2
0 and formed by the opposing step portions 16.
A concrete floor panel 1 was installed by filling the interior with mortar 9. However, in the above conventional example, it was necessary to weld one perforated plate to the beam 2 on site, and there was also a misalignment of the welding position of the perforated plate 19 or a dimensional error in the floor panel 1. In some cases, it is not possible to remove floor panel 1, and in this case, after welding it on site, it must be removed by fusing, the position adjusted again, and one perforated plate welded. It was necessary to take the time and effort to do so.

[Objective of the Invention J The present invention was invented in view of the above points, and its purpose is to attach a concrete floor panel to t7!1* without welding work on site. The installation of concrete-based floor panels provides an aesthetic experience, since it can be installed reliably and absorb errors in the floor panels, etc., and prevent them from shifting laterally.

[Disclosure of the Invention J The installation of the concrete floor panel of the present invention is as follows:
Place both ends of the concrete floor panel 1 on the adjacent beams 2, insert the bolts 4 into the holes 3 drilled near the ends of the floor panel 1, and insert the bolts 4 into the holes eccentrically from the center of the circular plate 5. Drill an eccentric hole 6 in the floor panel 1, position this circular plate 5 on the back side of the floor panel 1, insert the bolt 4 into the eccentric hole 6, attach the circular plate 5 to the floor panel 1, and attach the circular plate 5 to the outer circumference of the circular plate 5. A part of the beam 2 is in contact with the side end surface of the beam 2, and by adopting such a configuration, the above-mentioned conventional problem α can be solved and the object of the present invention can be achieved. This has been achieved. That is, in the present invention, by attaching the circular plate 5 to the floor panel 1 with the bolts 4 and applying a part of the outer circumference of the circular plate 5 to the gA end face of the beam 2, the floor placed on the beam 2 can be fixed. It is possible to install the panel 1 without shaking in the horizontal direction, and even if there is a dimensional error in the floor panel 1, etc. or an error in the position of the hole 3 drilled in the floor panel 1, the circular @5 Since the bolt 1 is inserted into the eccentric hole 6, by rotating the circular plate 5 around the bolt 1, these dimensional errors can be absorbed and the circular plate 5 can be securely brought into contact with the side end surface of the hole 2. It is now possible.

The invention will be explained in detail below with reference to Examples. A floor panel 1 made of concrete such as lightweight foamed concrete such as an ALC panel has holes 3 drilled near both ends in the longitudinal direction. The upper part of the hole 3 is a large diameter hole 3a. 9 In the figure, 5 is a circular plate, and the circular plate 5 has an eccentric hole 6 at a position eccentric from the center.
is perforated. A bolt 4 is inserted into the hole 3 of the floor panel 1 from above, and the part of the bolt 4 that protrudes toward the bottom surface of the floor panel 1 is inserted into the eccentric hole 6 of the circular plate 5. A nut 7 is screwed onto the lower end of the . The floor panel 1 is arranged between adjacent beams 2, and the floor panel 1
Both ya parts in the longitudinal direction are placed on the upper surface of the beam 2. As a result 2, in the embodiment shown in the drawings, a part of the outer periphery of the circular plate 5 is rotated around the bolt 4 inserted into the eccentric hole 6. The circular plate 5 is brought into contact with the side end surface of the upper flange 11 of the beam 2, and in this state, the nut 7 is tightened to attach the circular plate 5 to the back surface of the floor panel 1. By doing this, the floor panel 1 and It is possible to absorb the dimensional error of the first order in the hole 3 and prevent the floor panel 1 from moving in the X direction in Figure 1, and the force in the X direction is transmitted to the beam 2 via the circular plate 5 and borne. Here, at the end in the Y direction, which is the i direction perpendicular to the X direction, the wall panel support fixed to the top surface of the beam 2' is made of gold, Since the mortar 9 is filled between the panel 1 and the wall panel holder, the force in the Y direction shown in FIGS. 1 and 3 is borne by the metal fitting 8 of the wall panel holder.

In the wall panel holder, a concrete wall panel 10 made of lightweight foamed concrete or the like, such as an ALC panel, is attached to the metal fittings 8. In addition, in the present invention, since the floor panel 1 is made of concrete, it is sufficient to resist the force in the Z direction in FIG. It is.

However, if the lifting force of the floor panel 1 is to be borne by the metal fittings for more secure installation,
This is done as shown in Figure piS4. In other words, in FIG. 4, a locking hole 12 is drilled in advance at the top 72 holes 11 of the beam 2 at the factory, a pad f213 is applied to the bottom side of the circular plate 5, and a bolt is inserted into the insertion hole 14 of the pad plate 13. 4, a part of the outer circumference of the circular plate 5 is brought into contact with the side end surface of the upper flange 11 of the beam 2, and the locking protrusion 15 provided on the backing plate 13 is inserted into the locking hole 12 and locked. A nut 7 is screwed onto the lower end of the bolt 4 to connect the circular plate 5 to the floor panel 1.
It is attached to the lower surface of the cypress board 5 by applying the holder 13 to the circular cedar board 5. In this way, X, Y in Figure 4
, Z are borne by the backing plate 13 and the circular plate 5.

[Effects of the Invention] In the present invention, as described above, a circular plate is attached to a floor panel with bolts, and a part of the outer periphery of the circular plate is placed on the side end face of a beam, so that the circular plate is attached to the floor panel with bolts. It is a device that can be installed to prevent the floor panel on which it is placed from shaking laterally, and there is no need to weld perforated plates etc. to the beams on site as in the conventional method, and it is possible to attach the floor panel on site. This has the advantage of eliminating work, and even if there is a dimensional error in the floor panel or an error in the position of the hole drilled in the floor panel, the bolts can be inserted into the eccentric holes of the circular plate. By rotating the circular plate around the center, these dimensional errors can be absorbed and the circular plate can be reliably brought into contact with the side end surface of the beam.
