Problems solved by technology

However, there is a problem that the construction cost of the double floor will be increased by using such a shock-absorbing and sound-insulating thin-layer material.
In addition, there is a problem that the rubber-based base material deteriorates with long-term use, resulting in a decrease in durability.

Embodiment

[0037] Hereinafter, the present invention will be specifically described by illustrating the embodiments and experimental examples shown in the drawings.

[0038] Fig. 1 shows that at the floor surface of a base ground 100 such as a concrete slab, by means of a unit support foot 1 as a support foot, an underfloor liner 50 is supported and laid at a predetermined height level, and then an An embodiment of a soundproof floor structure formed by laying hard boards or high-density fiberboards 51 to form the lower floor in a double floor, and then laying floor covering materials 52 as floor covering materials.

[0039] Figure 2 to Figure 4 A preferred embodiment of unit support feet using hollow type support bolts is shown.

[0040] The unit support foot 1 of this embodiment includes an elastic base 10 formed of elastic materials such as rubber and having shockproof performance, and a foot member composed of a hollow support bolt 20 that is vertically arranged on the elastic base...

Abstract

A sound insulating floor structure comprises an underlying floor layer of a raised floor constructed by supporting a plurality of underlying floor panels at a predetermined height by means of a group of supporting legs installed on a foundation floor via elastic pedestals attached to the lower ends of the supporting legs, floor covering materials laid over the underlying floor layer, and intermediate materials laid between the underlying floor layer and the floor covering materials. The intermediate material is a hardboard or a high density fiberboard having the flexural strength of 35-50 [N / mm<2>], Young's modulus in flexure of 4,000-5,000 [N / mm<2>] and the density of 0.8-1.2 [g / cm<3>].

Description

technical field [0001] The present invention relates to a double-floor sound-insulating floor structure, and in particular relates to dry-type floor construction by constructing a double-floor in such a way as to form a space with the existing base floor in various buildings such as apartment houses. method to form a soundproof floor structure. Background technique [0002] The supporting feet set upright on the foundation ground through the elastic base support several sub-floor liners at a predetermined height level to form the lower floor in the double floor, and then lay the floor paving material on it through the cushion material. The floor structure is called a dry double floor structure, which is commonly used in buildings such as apartments and sports facilities. This dry double floor structure is provided with elastic bases such as cushioning rubber at the lower ends of the supporting feet, so that the impact applied to the double floor can be relieved. [0003] I...
