Description

High-performance inter-floor noise prevention structure {FLOOR NOISE PREVENTION STRUCTURE}

The present invention relates to a high-performance anti-noise structure between floors, and more specifically, it is possible to prevent or maximally prevent the generation of inter-floor noise through an efficient structure, as well as simple construction and convenient maintenance, resulting in cost. It relates to a high-performance interlayer noise prevention structure that can reduce the

A typical construction method for a building with two or more floors, such as an apartment or multi-family dwelling, consists of a wall-type structure in which a column made of concrete having a certain thickness and a slab supported by a wall are connected to form a single structure.

In other words, after completing the foundation work by constructing slabs supported on pillars and walls according to the number of floors of the building, the cement mortar is applied in a state where pipes such as heating and water supply pipes are arranged at regular intervals on the concrete slab. It is to be installed to a certain thickness.

A building having such a structure has a blocking performance to some extent against air transmission sounds transmitted through air, such as speech sounds and TV sounds.

However, as the floor, that is, the slab that divides the floors, is constructed only with concrete, noise and vibrations caused by shocks generated inside the corresponding floor of the building are easily transmitted to the adjacent household and the floor immediately below through the inter-floor slab.

The noise problem is mainly caused by external or internal shocks or vibrations, that is, noise between floors. The noise, the sound of moving furniture, and the noise between floors, which are generated when you work on the floor or wall, cause considerable discomfort to the neighboring households. There is a trend to further strengthen these soundproofing standards.

For reference, inter-floor noise is defined in Article 44 (1) of the Housing Act and Article 57 (1) 21 of the Enforcement Decree of the Housing Act. It is defined as the sound of using a washing machine, vacuum cleaner, or exercise equipment in the early hours, and the sound of flushing water in the bathroom and kitchen.

Therefore, the technology for blocking noise between floors is a very important factor in securing market competitiveness of building companies, and various technologies for preventing or reducing the occurrence of such noise have been proposed.

In particular, recently, the government is significantly strengthening the standard requirements for sound insulation, insulation, and reinforcement characteristics for buildings. Therefore, several companies are in the process of developing technologies for high-performance interlayer noise prevention structures.
