In the space of modern urbanization, due to limited land resources, buildings are developing towards high-rise and dense. With the changing times, people not only need a room, but also need a safer and quieter living space. However, it is inevitable that related sounds will be produced or generated in home life, because sound is the sound wave generated by the vibration of an object, which is transmitted to the human ear through the air, and then transmitted to the brain through the auditory nerve. Therefore, between floors, there are often noises such as falling objects, children jumping, sports equipment touching the ground, or bathroom drainage and showering, etc., which will affect the quiet quality of life of the whole family.

However, under the condition that the rigidity of the main structure of the building is not easy to change, floor decoration materials are bound to be the best means to improve the noise environment; and the current method generally used to improve floor noise is nothing more than thickening the floor, but due to The thicker the floor slabs, partition walls, and building exterior walls are, the more steel bars are required, and the sound insulation effect achieved by the thicker floor slab construction method is better. The higher the weight, the greater the risk of collapse, so it is not ideal in structure, so the construction method of thickening the floor slab will make the indoor space limited and unsafe and economical. Or, some builders try to improve by changing the pipe material or the sound insulation material of the ceiling, but this method cannot actually solve the problem of noise mutual interference between floors.

The comparison results between the construction method S100 of the sound-damping floor of the present invention and the construction method of the prior art will be observed below with the help of Table 1.

Table I

It can be seen from Table 1 that the construction method S100 of the sound damping floor proposed by the utility model can effectively reduce the sound waves generated by air borne sound, floor impact sound (including light and weight impact sound) and no indirect sound. Structure borne sound and other noises of water flow sound, and the construction method S100 of the sound damping floor proposed by the utility model is relatively easy for construction maintenance or area change.

The following table 2 is used to observe the comparison results of the sound collection test between the sound-damping floor 100 of the present invention and the existing sound-damping construction method for floor impact sound (including light and heavy impact sound).

Table II

It should be noted that the traditional floor (bare slab) is directly connected to the floor structure without any medium or elastic material as a buffer surface. Therefore, any sound transmission between floors will be obvious. 2. The weight impact test and the lightweight impact test done are based on the results of the traditional floor (bare slab) sound reception test, and then compare the sound reception test results of the Japanese-style elevated wooden floor and the sound damping floor 100 proposed by the utility model.

The weight impact test refers to the sound produced by the weight impact sound (tire) caused by the falling of heavy objects or the behavior of people's intense activities, that is, the floor weight impact sound. For example, the sound of a basketball falling, children's bouncing or running, and the sound of heavier and softer things. It can be seen from Table 2 that in the weight impact test, the sound damping floor 100 proposed by the present utility model does have an actual isolation effect on the weight impact sound.

In addition, for the light-weight impact test, the light-weight impact sound (tapping machine) refers to the sound generated by falling objects or moving furniture in the room, which is indirectly transmitted to the residents on the downstairs floor, which is light-weight impact sound. . For example, high-heeled shoes, shifting of table and chair legs, or falling of knives and forks, etc., make the sound made when relatively hard and light objects rub against the floor. It can be seen from Table 2 that in the light impact test, although the impact on the light impact sound can also be reduced, the sound damping floor proposed by the utility model can reduce more db values, so the sound damping floor of the utility model 100 The floor impact sound of the light impact source has been significantly improved, which fully demonstrates the effect of the utility model.

To sum up, in the sound-damping floor of the present utility model, the sound-damping layer is an elastic medium between the decorative surface material layer and the floor structure, so the sound-damping layer can be used as a buffer layer, and the sound-damping layer can be used to reduce the Any noise between floors to achieve the purpose of eliminating noise mutual interference between floors.

In addition, the construction method of the sound damping floor proposed by the utility model is relatively easy for construction maintenance or area change.

In addition, compared with the hollow soundproof floor (or hollow floor) in the prior art, the construction method adopted is to install sound-absorbing Styrofoam balls in the floor, which will have a hollow effect after cement grouting, so as to weaken However, the Styrofoam balls in the hollow soundproof floor slabs in the prior art do not cover the entire floor, so the sound insulation effect is still limited. Misplaced Styrofoam balls will reduce the overall seismic capacity of the hollow sound-insulating floor slab in the prior art. In contrast to the present utility model, the sound damping layer of the sound damping floor of the present utility model is composed of high-density Styrofoam board as a whole, and the sound damping layer is interposed between the elastic medium between the modified surface material layer and the floor structure to serve as a buffer layer , to improve the sound insulation effect, and the high-density styrofoam board is also provided with anti-shock rubber pads, which also have anti-shock ability, so the utility model does have the problem of improving the hollow sound-insulating floor slab in the prior art.

The above descriptions only describe the preferred specific implementation or examples of the technical means adopted by the present utility model to solve the problems, and are not intended to limit the scope of implementation of the utility model patent. That is, all changes and modifications that are consistent with the scope of the patent application of the utility model, or made in accordance with the scope of the patent of the utility model are covered by the scope of the patent of the utility model.
