Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vibration-proof floor structure for a building.

As a conventional anti-vibration countermeasure, elastic bodies such as rubber and air springs are inserted into various parts of a building to reduce vibrations. It is difficult to say that it is effective in cases where it has certain characteristics, and there are problems such as seismic safety cannot be ensured.

The present invention has been made in view of the above-mentioned points. Underfloor concrete is provided under the first floor floor, splices and floor bundles are fixed on the underfloor concrete through reinforcing metal fittings, and large tensions are placed on the splices and floor bundles. , reinforcing the main drawer, tethers, and floor bundles with braces, placing a joist on the above-mentioned main drawer, placing waterproof thick plywood on the joist, and laying tatami mats on the waterproof thick plywood. For floors on the second floor or higher, a reinforcing support beam is provided on the trunk, the second floor beam is connected to the reinforcing support beam via metal fittings, a joist is placed on the second floor beam, and a joist is installed on the joist. To provide a vibration-proof floor structure for a building, in which a waterproof thick plywood is covered and a tatami is laid on the waterproof thick plywood.

Figure 1 shows an example of a conventional one-story floor assembly structure, in which a large pull-out 3 is supported by a floor bundle 2 installed on a bundle stone 1.
A joist 4 is placed on top, a floorboard 7 is placed on the joist 4,
It has a structure in which a tatami mat 8 is laid on the floor plate 7, and the above-mentioned sill 3 is connected at right angles to a base 6 provided on a cloth foundation 5. Note that 9 is a pillar.

FIG. 2 shows an example of a conventional floor assembly structure for the second floor or higher. A joist 4 is provided on the second floor beam 11 which is connected to the pillar 9 at right angles through the box hardware 10. It has a structure in which a floor plate 7 is stretched and a folding 8 is laid on the floor plate 7, and 12 is a trunk holder.

Next, embodiments of the present invention will be described in detail with reference to FIGS. 3 and 4. Figure 3 shows 1 according to the present invention.
This shows a floor construction. After removing the conventional floor construction and leveling the ground under the building's floor, gravel 19 is laid on the foundation, and concrete 18 under the floor is laid on top of the gravel 19. , the underfloor concrete 18
A floor bundle 2 is fixed on top with bolts 21 via an L-shaped metal fitting 20, a wire 3 is provided on the floor bundle 2, a splice 13 is provided at both ends of the wire 3, and the wires 13 and Pull 3
The floor bundles 2 and the main pullers 3 are alternately reinforced on one side with a support rod 16, and the above-mentioned attachment bundles 13 and the main puller 3 are reinforced with support rods 16 from both sides. A new floor bundle 15 and attachments 13 are fixed on the underfloor concrete 18 with bolts 21 via L-shaped fittings 20, and a new floor bundle 14 is provided on the new floor bundle 15 and attachments 13. and the new floor bundle 15 are alternately reinforced on one side with a support rod 16, and the above-mentioned attachment bundle 13 and the above-mentioned new Ohiki 14 are reinforced with support rods 16 on both sides,
It has a structure in which a joist 4 is arranged on the above-mentioned Ohiki 3 and the new Ohiki 14, a waterproof thick plywood 17 is placed on the joist 4, and a tatami mat 8 is laid on the waterproof thick plywood 17, and 5 is a cloth foundation. , 6 is the base, and 9 is the pillar.

FIG. 4 shows a floor assembly structure for the second floor or higher according to the present invention, in which a reinforcing support beam 22 is provided on the trunk sill 12,
A new second-story beam 23 is fixed to the reinforcing support beam 22 between the second-story beams 11 via a beam support fitting 24, and a joist 4 is placed on the second-story beam 11 and the new second-story beam 23. A waterproof thick plywood 17 is placed on top of the waterproof thick plywood 17.
It has a structure in which a tatami mat 8 is placed on top, and 9 is a pillar.
Although this embodiment shows an example in which the reinforcing support beam 22 is used, the reinforcing support beam 22 does not necessarily need to be provided depending on the conditions. Furthermore, although the above embodiment has been described in the case of a Japanese-style room, in the case of a Western-style room, a floor finishing material is pasted up on the waterproof thick plywood 17.

In the case of reinforcing both the first floor floor and the floors above the second floor, it is important to ensure the cross-sectional performance and rigidity by reinforcing or replacing the defects of each member and the parts that have deteriorated significantly over time.

As explained above, the building vibration isolation floor structure according to the present invention consistently exhibits a stable vibration isolation effect based on numerous experimental examples conducted by the inventor. Note that the present invention is not limited to the above-mentioned examples, and may be constructed by combining necessary construction methods without departing from the spirit of the present invention.
