Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a soundproof floor structure in an apartment complex or the like.

In apartment complexes, floor impact sounds from upper floors, such as footsteps and floor impact noises caused by moving furniture, are transmitted directly to the lower floors through slabs, so a floor structure that reduces floor impact noise from upper floors is desired.

For this reason, various soundproof floor structures have been proposed, but for example, in a floating floor structure, variations in construction quality immediately affect the performance, making it difficult to guarantee the quality of soundproofing performance.

In addition, problems are likely to occur from a long-term perspective due to creep settling of the floor cushioning material and cracking of the floating floor material.

In addition, there are issues such as space for piping equipment and floor thickness.In particular, apartment complexes are owned in sections, so piping must fit within the same residence, and these issues must also be addressed.

The soundproof floor structure of the present invention has been proposed to address the above-mentioned problems, and aims to improve the soundproofing performance against impact noise and to make effective use of the structure space by streamlining the floor structure.

FIG. 1 shows an embodiment □ of the present invention, in which a reverse lip slab structure is adopted as shown in the figure, and the lip 2 of the reverse rib slab 1 is
A joist or floor panel 4 is placed in the notch 7 provided on both sides of the upper part of the joist with a cushioning material 3 interposed therebetween, and a flat flooring material 5 is placed on top of it. Furthermore, a floor finishing material 6 such as a finished floor or a carpet is pasted on this flooring material 5 to construct a floor. - At this time, a gap is created between the upper surface of the lip 2 and the lower surface of the floor material 3, so that a portion of the impact directly above the lip 2 can be absorbed by the deflection of the floor material 5, etc.

Further, as the cushioning material 3, vibration-proof rubber, synthetic resin sponge, and other commonly used cushioning materials can be used.

As the reverse lip slab 1, there is a single force facing push slab with lips 2 provided on one side only as shown in FIGS. 2 and 3, or a double lip slab with lips 2 provided in two directions as shown in FIGS. Using a directional lip slab, lip 2 acts as a beam.

Moreover, in FIG. 1, 8 is a through hole for equipment piping provided on the side surface of the lip 2.

Note that the level of heavy impact sound such as footsteps transmitted from the upper floor slab is mainly determined by the slab thickness and surface density. If the density of the slab material is constant, the impact sound level can be lowered by increasing the slab thickness, but the weight of the slab is large. Therefore, in this invention, 1.1 is provided with a cross-section -::・, 70 thick "reverse beam" at the required position of 3, 7 degrees, to directly transmit the impact load to this, and to provide a buffer between the reverse beam and the floor slab. By interposing the material, the sound reduction effect is achieved without significantly increasing the weight of the syslab.

The present invention has the above configuration and has the following advantages and features.

■ Good soundproofing performance against floor impact noise, and performance defects due to construction variations are less likely to occur. Note that impact noise can be counteracted by the deflection of flooring materials, the rigidity of lip parts, etc.

■Since the joists or floor panels are placed in the notch of the lip, the floor height can be reduced by the height of the notch, compared to the case where they are placed on the top of the lip. In addition, a portion of the impact directly above the lip can be absorbed by the deflection of the flooring, etc.

■ The inside of the lip of the reverse slab can be used as a space for equipment piping, and the structure allows flooring to be placed on the lip, making it convenient for maintenance to prevent pipe corrosion. Japanese room 1
From clam to Western-style room, Western-style power 1. It can accommodate future changes in use, such as a Japanese-style room.

■ Since a reverse lip slab is used, there is no need for a direct ceiling, and the floor can be constructed without installing small beams, so there are no beam shapes in the room.

■ Modularization is possible by determining specifications such as spacing, height, and width. With this modularization, floor formwork or PC boards can be made at low cost.0 ■ By controlling the cross-sectional performance of the lip of the reverse slab, the slab thickness can be made constant.

■ The double floor structure keeps the floor warm and keeps the bottom from getting cold. Additionally, a floor heating system can be installed.

■ The space under the floor can be used as an air supply route for gas combustion appliances, a heat storage tank for air conditioning, or an underfloor storage space.
