Novel sound insulating floor slab

Abstract

The invention provides a novel sound insulating floor slab, which comprises a floor slab structural layer, a floor slab surface layer and at least one arched sound-absorbing shed positioned between the floor slab structural layer and the floor slab surface layer, wherein the arched sound-absorbing sheds comprise bottom boards and arched boards; the bottom boards seal up openings of the arched boards to form arched sound-absorbing chambers; the bottom boards are attached to the floor slab structural layer; the arched sound-absorbing chambers are also provided with sound-absorbing boards; the two arched sound-absorbing sheds can be arrayed sequentially and closely, and also can be arrayed at intervals; steel bar meshes are arranged at an interval position; the spaced arched sound-absorbing sheds can be fixed by a fixer, and also can be directly inserted or the two arched sound-absorbing sheds are respectively connected by a sound-absorbing shed connector or sound-absorbing shed sealing covers cover free ends of the arched sound-absorbing sheds so as to seal up the arched sound-absorbing chambers; and the arched sound-absorbing sheds also can be provided with strengthening ribs. The novel sound insulating floor slab has the advantages of novel structure, light weight, good effect of sound insulation, strong load-bearing capacity, effective reduction of the thickness of the floor slab, minimum influence on floor clear height and simple and easy construction.

Description

Technical field [0001] The present invention relates to the technical field of floor slabs, more specifically, to the technical field of sound-proof floor slabs, in particular to a new type of sound-proof floor slab. Background technique [0002] Modern building structures often focus on thermal insulation and waterproof performance, but ignore the ability of floor slab sound insulation. The sound of children bouncing upstairs, the sound of slippers tapping when people walk, the sound of falling heavy objects, and the sound of dragging tables and chairs can be transmitted and affect the lives of the residents downstairs. Insufficient understanding and indifference to noise issues has made noise governance more difficult. [0003] The above-mentioned noise belongs to vibration and sound transmission, which mainly vibrates through the floor and propagates along the steel connecting layer of the building structure. Finally, the vibration structure radiates to the receiving space to f...

AI Technical Summary

Problems solved by technology

The sound insulation methods of this kind of vibration sound transmission belonging to impact sound include: one is to weaken the vibration caused by the vibration source hitting the floor, but it is difficult to be widely used in practice; the other is to block the vibration structure from radiating airborne sound to the receiving space, which is It is usually solved by making a sound-proof ceiling under the floor, and the ceiling must be closed and elastically connected to the floor, which is not popular in terms of cost and occupied space; the third is to block the transmission of vibration in the floor structure, the most effective way It is a floating floor, which is to set a layer of elastic sound insulation cushion between the floor surface and the structural layer, such as a sponge layer, a plastic layer and other sound insulation layers, but the sound insulation effect is limited, the load-bearing capacity is poor, the construction is difficult, and it is easy to fade over time. Compression deformation; there are also hollow bricks installed between the floor surface and the structural layer, but the weight is large, resulting in a large thickness of the floor and increased construction difficulty
