Description
Technical Field
The utility model belongs to the field of assembly type buildings, and particularly relates to a hollow PVC inner formwork wall structure with multiple sound insulation.
Background
The frame shear wall building structure is increasingly used in the existing building, and the wall is adopted to divide the floor of the frame shear wall into spaces with different functions. The partition wall in the prior art is roughly divided into two types, one type is an autoclaved aerated concrete block wall body, and the other type is a light steel keel partition wall.
The light autoclaved aerated concrete block wall and the light steel keel partition wall have certain limitations due to the performance characteristics of the used materials of the products. Concrete blocks in the lightweight autoclaved aerated concrete block wall generally need to be built above the structural beams due to the problem of the weight of the concrete blocks, so that the weight of the floor surface can be reduced, but many walls cannot be accurately positioned above the structural beams. When the autoclaved aerated concrete block wall body is built in a building (particularly a high-rise building), if the autoclaved aerated concrete block wall body cannot be accurately positioned at the position of a structural beam, the load of a floor surface is increased, and potential safety hazards are caused. In addition, as the autoclaved aerated concrete blocks are heavy and cannot be manufactured into large blocks for installation, each square wall body is built by small blocks, and the construction efficiency is low. In addition, as the autoclaved aerated concrete block cannot be embedded in advance, clamping grooves are needed when pipelines are arranged in the later period, and the grooving causes a large amount of dust on site, thereby causing environmental pollution. Although the light gauge steel partition wall has the advantages of convenience in construction and high quality, the sound insulation effect of the light gauge steel partition wall is poor, and although sound insulation cotton can be filled in the light gauge steel partition wall, the sound insulation requirement cannot be met. On the other hand, the surface layer of the light steel keel partition wall is generally decorated by adopting a gypsum board, the gypsum board has the characteristic of easy water absorption, the waterproof performance is very poor, the strength of the gypsum board material is low, the gypsum board material cannot be used in the areas needing wall tiles such as toilets and kitchens, and the application range is limited. In addition, because the gypsum board of light gauge steel partition wall is two kinds of different materials with former building wall, the fracture phenomenon often can take place in handing-over department, is difficult to restore, influences decorative effect.
In order to overcome the defects of the autoclaved aerated concrete block partition wall and the light steel keel partition wall, a PVC hollow wall body can be adopted, a light PVC material is used as an inner template, cement mortar is coated on the surface of the PVC hollow wall body to form the wall body, and the wall body is light in weight, good in waterproof and sound insulation effects. However, in places with high sound insulation requirements (such as a music hall, a KTV and the like), the sound insulation capability of the existing PVC hollow wall body still cannot meet the requirements, and the space division effect is influenced.
