Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a floor structure that is installed directly on a floor base such as a concrete slab.

[Conventional technology]

BACKGROUND OF THE INVENTION In conventional houses, particularly apartment buildings such as condominiums, the floor finish was generally constructed by pasting paper stacks directly onto a floor base such as a concrete slab. However, this carpet has hygienic problems, such as the appearance of mites.

Under these circumstances, wood finishing materials that have a clean appearance and are easy to clean have recently attracted attention, and the need for them is increasing.

[Problem to be solved]

However, such a relatively hard finishing material greatly transmits the living noises of the upper floors, especially the light impact sound of the floor, to the lower floors, making sound insulation measures an important issue.

Therefore, a method in which a synthetic resin foam or the like is pasted on the back side of a wood finishing material has been proposed, but it has not reached the point where it satisfies the performance of the sound insulation grade L-55 or higher, which is the user's supply level. It is also considered to use a thicker synthetic resin foam that satisfies the specified sound insulation requirements, but in this case, the floor covering material itself becomes soft and if furniture is placed on top of it, It has problems such as a large amount of sinking, a too soft foot feel that does not feel like wood, and a tendency to make floor noise, so it is not a sufficient deciding factor.

In view of the above-mentioned circumstances, it is an object of the present invention to provide a floor structure that is lightweight and has excellent impact sound insulation properties, and that does not cause floor rumbling or the like due to its hard texture.

[Means to solve the problem]

That is, the present invention relates to a shock absorber that is soft and has air circulation, and a hard vent that is provided on the buffer and has an air passageway for escaping air discharged from the buffer, or this hard vent. A soft or hard ventilator is provided on the top of the panel to form the lower panel, and a soft or hard ventilator with air circulation is provided on the bottom surface of the surface finishing material made of a relatively hard material such as wood or synthetic resin. The upper panel is constructed only from gas arranged or formed or surface finishing material, a number of lower panels are laid on a floor base such as a concrete slab, and the upper panel is attached to the lower panel.

[Effect]

Generally speaking, in the floor structure of the present invention, when a shock absorber is compressed by an impact, the air held within the shock absorber is compressed and acts like a spring, and the shock absorber may not be able to fully exert its shock-absorbing effect. Taking into consideration the fact that there is Even if an impact force is applied to the floor surface side, the shock absorber effectively exhibits a damping and vibration-proofing effect to effectively absorb and reduce the impact force, thereby improving impact sound isolation characteristics.
