Description

Wall body unit, sound insulation wall and sound insulation wall system of sound insulation wall

Technical Field

The utility model belongs to the technical field of sound insulation walls, and particularly relates to a wall unit of an assembled sound insulation wall, the assembled sound insulation wall and an assembled sound insulation wall system.

Background

A sound-insulating wall is a building structure for reducing the passage of sound to isolate the sound. The sound insulation wall plays an important role in the design and construction of building engineering, and can provide good sound insulation capability by adding certain materials on the premise of not changing the existing building structure, so that the noise inside and outside the building is isolated, and the living and working environments of people are ensured to be quiet and harmonious.

The requirements on the sound insulation effect are continuously improved at any time of social development, and the sound insulation wall is also continuously developed. The development of sound-insulating walls has been through several stages: the first stage is to intercept noise by utilizing the self-quality of the wall body, and the sound insulation wall in the first stage mainly depends on the sound insulation effect of the self-quality of the wall body, has a simple structure but poor sound insulation effect, and can only isolate impact sound insulation and medium-low frequency noise sound insulation; the stage of adding the sound absorption shielding layer is to add sound absorption shielding layers such as sound absorption cotton, asbestos boards and the like on the surface of the wall body, so that the sound insulation effect of medium-high frequency noise is improved, and the sound insulation effect is greatly improved by absorbing and blocking the medium-high frequency noise; the vibration isolation layer is added on the surface or inside of the wall body, and the vibration isolation layer is used for isolating the noise on the surface of the wall body so as to improve the sound insulation effect of low frequency and impact noise. The assembly type interior installation means that dry construction is adopted, and decoration parts, equipment pipelines and the like produced by factories are assembled and installed on a construction site, so that the integrated design of assembly decoration and a structural system, an outer wall system, an inner wall system and an equipment pipeline system is comprehensively considered. The assembly type interior is innovative and simplified in construction flow, decoration can be completed only by simple tools and steps, site construction cutting is reduced, workload and working cost are greatly reduced, and timeliness of decoration is guaranteed. The assembly type process technology provides a new idea for the arrangement of the sound insulation wall.

The existing assembly type sound insulation wall comprises a mortise-and-tenon type connecting sound insulation wall, a bolt connecting sound insulation wall, a hinge type connecting sound insulation wall, an adhesive type connecting sound insulation wall and the like. After the mortise and tenon type mortises are formed in the prefabricated wall body, the joint is sealed by casting concrete or grouting to realize wall connection, shrinkage of the concrete or grouting material at the joint of the sound-insulating wall and cracks generated by the shrinkage can influence the air tightness of the joint, low-frequency noise is easy to penetrate, and vibration formed in the hardening process of the material can also influence the sound-insulating effect. Bolt holes are formed in the joints of the prefabricated walls, connecting steel plates or connecting pieces are connected with the walls through bolts to achieve wall connection, large gaps are formed in the surfaces of the walls through the bolt connection holes of the sound insulation walls, medium-high frequency noise is transmitted from the joints easily, and the sound insulation of low frequency noise is affected due to insufficient tightness of the bolt connection. Hinge type sets up the hinge hole at prefabricated wall body's joint edge in order to articulate the connection lip of wall body, and the sealed hinge of rethread sealing strip is around in order to realize the connection of wall body, and the hinged joint of this kind of sound insulation wall needs to set up great hinge hole on the wall body surface, and this can show the separation of weakening sound insulation wall to high frequency noise, also can influence whole sound insulation effect if the sealing strip is sealed poorly. The adhesive is used for uniformly coating the liquid or solid adhesive on the connecting surface of the prefabricated wall body, and connecting the two wall bodies through chemical reaction hardening or drying after the wall bodies are aligned. If the adhesive layers are uneven and discontinuous, gaps are formed between the walls, so that the middle-high frequency noise is easier to penetrate from the connecting positions. Meanwhile, the adhesive has poor sound insulation effect, and can not provide good barrier to low-frequency noise.

It follows that the strategy for setting up the assembled sound insulation wall is still to be optimized.
