Description

Floor system for preventing noise and vibration and its construction method {Floor system for preventing noise and vibration and its construction method}

The present invention relates to a flooring system for noise and vibration reduction and a construction method thereof, which can be installed in buildings such as indoor stadiums, indoor sports fields, gymnasiums, auditoriums, classrooms, classrooms, exhibition halls, etc. to reduce or prevent noise and vibration. and a floor system for vibration reduction and its construction method.

In general, the floors of buildings such as gymnasiums, auditoriums, and classrooms are made of concrete, so separate flooring materials are constructed, and the flooring materials are constructed taking into account the flatness, shock absorption, and vibration buffering of the concrete floor.

Conventionally, a number of support blocks to adjust the height are arranged and installed at appropriate intervals on the indoor concrete floor of a building, and after square timbers are installed to support the pillars, plywood and floor boards are sequentially stacked and installed on top of the square timbers. In order to absorb the shock caused by the load transmitted through the floor board, a pad made of elastic material is installed between the support and the square lumber, or between the square lumber and the plywood.

However, the conventional floor structure as described above has the effect of reducing vibration transmitted through the floor by the support member and pad, but does not reduce or prevent noise caused by the load or impact of the floor, and as a result, people There were various problems, such as noise generated by activities such as movement, indoor games, sports practice, physical training, etc., being transmitted through the floor concrete (floor slab) of the building, deteriorating the comfort of the building.
