DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows that both ends of a lower panel 21, especially a metallic lower panel 21B are supported and fixed to beams 2 and 2 on both sides, and a floor panel body is provided above the lower panel 21B. The upper panel 1, particularly the metallic upper panel 1A, is arranged so as to form a constant space S between the upper panel 1A and the upper surface of the lower panel 21B.
2 shows a mounting structure of a double-structure floor panel in which both ends are supported and fixed to the beams 2 and 2.

As shown in FIGS. 2A and 3, the upper panel 1A, which is the main body of the floor panel, has both ends of a cylindrical body 6 formed of a metal plate in the shape of a horizontally long rectangle, with both ends made of metal. This is a panel formed by forming a hermetically sealed panel body 8 that is closed by a part closing member 7A, and filling the panel body 8 with a filler 9 such as cement-based aerated milk. The end closing member 7A of the upper panel 1A is formed of a metal plate that is thicker (or has a thickness equivalent to it) than the metal plate forming the tubular body 6 and has a U-shaped cross section. The plate portion 10 is provided with a bolt hole 12, and the upper plate portion 11 is provided with a bolt tightening work hole 13. Lower panel 21
B has almost the same configuration as the upper panel 1A, but the upper plate portion 10 of the end closing member 7B that closes the end portion of the tubular body 6 is the panel mounting plate portion, and the lower plate portion 11 is the upper portion. Board part 1
It is different from the panel 1A in that it is formed shorter than zero.

As shown in FIGS. 1 and 3, the beam 2 is made of H-shaped steel, and bolt holes 14 are provided in the upper flange 2a thereof at regular intervals in the longitudinal direction. The length of each of the upper panel 1A and the lower panel 21B is 10
The width is about 500 to 1500 mm, and the span between the beams 2 and 1000 is about 1000 to 1,000 mm.
The upper panel 1A and the lower panel 21B of 3000 mm can be bridged to 3000 mm or less.

Among the floor panels having the double panel structure consisting of the upper panel 1A and the lower panel 21B as described above, the upper panel 1A is the floor panel body and bears the weight and load of itself. Shall be formed to have sufficient rigidity. Also, the lower panel 21B
Shall not bear the load, but shall be formed to have sufficient rigidity to withstand its own weight and the load during construction work. The lower panel 21B is the upper panel 1A.
It may be formed thinner.

The floor panel mounting structure having the double panel structure will be described in detail as shown in FIG.
First, the end closing member 7B which is the end of the lower panel 21B.
The panel mounting plate portion 10 is placed on the upper flange 2a of the beam 2, and the bolt holes 14 of the upper flange 2a to the bolt holes 12 of the panel mounting plate portion 10 (as shown in FIG. 2B). , Which are provided at two places on the left and right), the bolt 4 is passed upward, and the nut 5 is strongly tightened to lower the panel 21B.
The end portion of is fixed to the beam 2.

Thereafter, another nut 5 is screwed onto the upper side of the bolt 4, and the panel mounting plate portion 10 of the end closing member 7A which is the end portion of the upper panel 1A is screwed onto the upper side of the nut 17. 2 through which the bolt holes 12 (as shown in FIG. 2 (A)) are inserted and contact the upper and lower sides of the bolt hole 12, respectively. 3A is fitted into the bolt 4, and the panel mounting plate 10 is sandwiched between the upper and lower seats 3A and 3A, another nut 5 screwed to the upper end of the bolt 4 is tightened, and thus the upper panel 1A is fixed to the bolt 4. The upper panel 1A is fixed at a required height above the lower panel 21B fixed on the beam 2 by the common bolt 4 and the nut 5 by fixing the upper panel 1A to the upper side of the upper panel 1A of FIG. As shown in Forming a constant parallel space S between the upper surface and the lower surface of the upper panel 1A Le 21B.

In this case, the space S formed between the upper surface of the lower panel 21B and the lower surface of the upper panel 1A forms a sound-insulating air layer and absorbs vibrations and shocks generated in the upper panel 1A. As a result, it is possible to prevent the propagation to the lower floor, thereby improving the vibration and sound insulation performance of the floor panel. If a sound absorbing material is inserted into the space S after securing an appropriate air layer, the sound insulation effect in the high frequency range is significantly improved. Further, this space portion S also functions as a heat insulating space. Further, in this case, the upper panel 1A has the panel mounting plate portions 10 provided at both ends of the panel 1A from above and below by the seats 3A made of a viscoelastic polymer material arranged on both upper and lower sides of the bolt hole 12. Since it is supported on the bolt 4 in a sandwiched state, vibrations and impacts generated on the upper panel 1A are absorbed by the abutment seat 3A and transmitted to the lower panel 21B and the beam 2 via the bolt 4. As a result, the vibration and sound insulation performance of the floor panel is further improved.

Although the upper nut 5 for fixing the panel mounting plate portion 10 of the upper panel 1A to the bolt 4 via the abutment seat 3A needs to be tightened with a certain constant torque,
Be careful not to overtighten. This is because if the nut 5 is tightened too much, the abutment seat 3A is excessively compressed and its vibration and shock absorbing performance is deteriorated. On the other hand, since the bolt 4 and the nut 5 for fixing the end portion of the lower panel 21B to the beam 2 do not have the abutment seat 3A, the nut 5 can be tightened sufficiently strongly,
Thereby, the bolts 4 can be firmly erected and fixed to the beam 2, and the end portions of the lower panel 21B can be firmly fixed to the beam 2, so that the horizontal force generated in the building during a typhoon or earthquake can be applied to the beam 2.
Can be sufficiently transmitted to, eliminating the need for braces.

The above-mentioned pad 3 is a near-gel body of ultra-low hardness, which is made of a viscoelastic polymer material whose main material is silicon and has excellent vibration absorption and shock absorption, and also has durability. It is a super soft elastomer. Then, on the abutment seat 3, a bush-shaped abutment seat 3A or a tip-shaped abutment seat 3C as shown in FIG. 4A, and a tape formed to have a required width as shown in FIG. 4B. There is a sheet-shaped pad 3B, and although not shown, there is also a sheet-shaped pad.
In the case of the tip-shaped abutment seat 3C, it is preferable to make a bolt hole as shown in the drawing. As such a base 3,
For example, those sold under the registered trademark name of "αGEL" by Geltec Co., Ltd., or those sold under the trade name of "Haplagel" by Polysys Co., Ltd. can be used.

A pad 3 made of the above viscoelastic polymer material
Has an excellent effect on absorbing vibrations and shocks. For example, in a raw egg drop test from 18m above the ground, which is equivalent to the 6th floor of a building, a thickness of 2cm formed from the same material as the base 3 The sheet allows you to stop the egg without breaking it, and it has a lower resonance point and a lower resonance magnification than the conventional high-performance anti-vibration rubber. It has excellent anti-vibration performance. FIG. 13 (A) shows a base 3 made of a viscoelastic polymer material.
And a high-performance anti-vibration rubber, and FIG. 3B shows a comparison of damping characteristics with and without the abutment seat 3.

This occurs on the upper panel 1A by supporting and fixing both ends of the metallic upper panel 1A on both beams 2 and 2 via the pad 3 made of the viscoelastic polymer material as described above. Vibration and shock are absorbed by the seat 3A,
It is possible to prevent vibrations and impacts from propagating to the lower floors and improve vibration and sound insulation performance. Further, in the case of the metallic upper panel 1A, as described with reference to FIG. 3, the seats 3 are arranged on the upper and lower sides of the bolt hole 12 of the panel mounting plate portion 10, respectively, and the panel mounting plate portion 10 is arranged. By fixing it to the required height position on the beam 2 with the bolt 4 and the nut 5 in a state of being sandwiched between the upper and lower abutment seats 3A and 3A, it is possible to effectively absorb the vibration and shock in the upper panel 1A.

When using the above-mentioned pad base 3 when using the bush-shaped pad 3A, when the bolt 4 is passed from the bolt hole 14 of the beam 2 to the bolt hole 12 on the floor panel 1A side, the bolt 4 is pressed against the bolt 4. It suffices to fit the seat 3A, and when the tape-shaped pad 3 is used, as shown in FIG. 4C, the tape-shaped pad 3 is previously mounted on the upper flange 2a of the beam 2.
And the hole 14o is opened at a required position of the tape-shaped pad 3 corresponding to the bolt hole 14 provided on the upper flange 2a. A bolt hole is also opened in the tip-shaped pad 3C. Although not shown in the drawings, the tape-shaped abutment seat 3 has an adhesive layer formed on one side thereof, and can be attached to the upper surface of the beam 2 via this adhesive layer.

By sticking it on the upper surface side of the lower panel 21C so as to close 0, the fireproofing treatment of the joint portion 30 can be easily and easily performed. Although not shown, as in the case of FIG. 12, a joint portion between adjacent lower panels 21 is closed and a sufficient air layer is secured without filling the space S with the upper panel 1. By disposing a fireproof coating material having a high sound absorbing property such as rock wool or a ceramic sheet on the upper surface side of the lower panel so as to entirely cover the upper surface side of the lower panel 21 in the state, simplification of the fireproof treatment is achieved. The sound insulation performance of the floor panel is further improved. The upper panel 1 and the lower panel 21 are both fireproof panels.

The reason for disposing the refractory coating material 31 on the upper surface side of the lower panel 21C so as to close the joint portion 30 between the lower panels 21 is as follows.
That is, when a fire occurs on the lower floor, the flame is generated by the lower panel 21C which is the floor panel on the upper floor forming the ceiling of the lower floor.
While heating, the space portion S between the lower panel 21 and the upper panel 1 penetrates from the joint portion 30 between the adjacent lower panels 21 into the joint portion 32 between the upper panel 1 and the space portion S. Although it passes through and goes to the upper floor side, in this case, if the joint part 30 between the lower panels 21C is closed, the fire can be stopped to the minimum extent,
As described above, the joint portion 30 on the lower panel 21 side is closed by the fireproof coating material 31. In addition, in the installation work of the double-structure floor panel composed of the upper panel 1 and the lower panel 21, the lower panel 21 is mounted on the beam 2 first. By disposing the fireproof coating 31 on the upper surface side, fireproof treatment can be easily and easily performed.
Furthermore, by disposing the fireproof coating material 31 on the upper surface side of the lower panel 21 so as to close the joint portion 30, the fireproof coating material cannot be seen from the outside, so that it is possible to make a room without a ceiling.

Generally, in the case of the dry method, it is difficult to perform fireproof treatment on the joints of the panel, and it is necessary to apply a fireproof coating on the entire lower surface of the panel. Since the fireproof coating material 31 can be arranged from the upper surface side of the panel 21, the fireproof treatment becomes easy. Further, since the fireproofing treatment of the lower panel 21 may be a slight treatment to shield the flame, the work becomes easier.
