Novel floating build floor and its construction method

Abstract

The invention relates to a novel floating floor and a building and constructing method for the same. The novel floating floor mainly comprises a reinforced concrete layer, a soundproof layer, a concrete cushion and a wood floor or other decorative floor on the concrete cushion, wherein, the soundproof layer is arranged between the reinforced concrete layer and the concrete cushion. The soundproof layer in the novel floating floor is made of polyolefin foaming materials which are formed by composition of a plurality of layers or by primary foaming and are provided with upper surface structures and lower surface structures. The total thickness of the polyolefin foaming materials is between 11 and 20 millimeters; the thickness of the upper layer is between 3 and 6 millimeters, and the density of the upper layer is between 50 and 100 kilograms per cubic meter; the thickness of the intermediate layer is between 5 and 8 millimeters, and the density of the intermediate layer is between 30 and 50 kilograms per cubic meter; and the thickness of the lower layer is between 3 and 6 millimeters, and the density of the lower layer is between 50 and 100 kilograms per cubic meter. The floating floor is waterproof, moistureproof and mildewproof, is small in thickness and light in weight, and has no pollution; and the floating floor does not require special construction equipment, can be conveniently laid, and is difficult to form rigid connection with a foundation floor and walling to create a sound bridge. The novel floating floor overcomes the defects of the prior floating floor, simultaneously has a good soundproof effect, is economic and practical, and has obvious effect.

Description

technical field [0001] The invention belongs to the field of building materials and construction, in particular to a novel floating floor slab and a building construction method thereof. Background technique [0002] Sound insulation is an important environmental protection measure in modern buildings. Construction noise includes two forms of airborne sound and impact sound, and most of the noise transmitted through the floor is impact sound. The impact sound of buildings is mainly the noise generated by the collision between objects and building components, and the vibration waves propagate along the building structure and radiate into the surrounding air. In general buildings, the floor is the main building component that generates impact noise. For example, the collision of door and window switches, objects falling on the ground, dragging of tables and chairs, children playing, and the knocking of heels when people walk on the floor will all cause impact. noise.

Problems solved by technology

[0004] The application number is 200710130940.2, which is called a composite sound-insulating floor and its building construction method. A composite sound-insulating floor is mentioned, but its multi-layer composite causes the cost to be too high, and the addition of extruded boards and films has caused construction difficulties and costs. Increase

[0005] Traditional floating floor sound insulation materials generally use rock wool boards, glass wool boards, wood fiber boards, and sugarcane boards. However, these materials are prone to mold and even lose their sound insulation functions after absorbing water and moisture. Therefore, strict waterproofing must be carried out during construction.

The increase in cost and the complexity of construction technology have directly led to the increase in the cost of this type of material and the reduction in cost performance, so it has been difficult to promote it on a large scale.

[0006] The above existing technologies undoubtedly have a certain sound insulation effect, but practice has proved that the sound insulation effect is not ideal or has the disadvantages of difficult construction or high cost
