[0023] refer to Figure 1-4 Now, a sound insulation and shock absorption device for building floors provided by an embodiment of the utility model is described. The sound insulation and shock absorption device for building floors comprises a floor 1, which is composed of an upper plate body 101 and a lower plate body 102. A first groove 8 is provided on the lower end surface of the upper plate body 101, and a second groove 9 is provided on the upper end surface of the lower plate body 102. The first groove 8 and the second groove 9 together form a sound absorption cavity, and a sound absorption component is arranged inside the sound absorption cavity. A sound-absorbing blanket 2 is arranged on the upper end of the upper plate body 101, and a shock-absorbing pad 5 is arranged on the lower end of the lower plate body 102.

[0024] Specifically, since the floor 1 is composed of an upper plate body 101 and a lower plate body 102, it is convenient to install the sound-absorbing component inside the floor 1. After the floor 1 is assembled, the floor 1 is spliced ​​on the floor of the floor, so that the noise generated upstairs will be initially absorbed by the sound-absorbing blanket 2, and the weakened noise enters the sound-absorbing cavity. With the cooperation of the sound-absorbing component, the noise can be weakened again, thereby improving the sound insulation effect. At the same time, with the cooperation of the shock-absorbing pad 5, the shock-absorbing effect can be improved, effectively preventing the noise generated by the vibration from affecting the lives of the residents downstairs.

[0025] An insertion groove 6 is provided on the upper end surface of the upper plate body 101 and the lower end surface of the lower plate body 102. An insertion strip 7 is slidably connected inside the insertion groove 6. The two insertion strips 7 are fixedly connected to the sound-absorbing blanket 2 and the shock-absorbing pad 5 respectively. By setting the insertion groove 6 and the insertion strip 7, the sound-absorbing blanket 2 and the shock-absorbing pad 5 can be respectively connected to the upper and lower ends of the floor 1 during operation, so that the floor 1 can be easily spliced.

[0026] The left end faces of the upper plate body 101 and the lower plate body 102 are both provided with installation grooves 3, and the installation grooves 3 are in an arc shape. The right ends of the lower plate body 102 and the upper plate body 101 are fixedly connected with installation blocks 4, and the installation blocks 4 correspond to the installation grooves 3. By setting the installation grooves 3 and the installation blocks 4, when working, with the cooperation of the installation grooves 3 and the installation blocks 4, it is convenient to splice the two floors 1 together.

[0027] The sound-absorbing component includes sound-absorbing cotton 10 and a pointed head 11. The sound-absorbing cotton 10 is fixedly connected to the bottom end of the sound-absorbing cavity, and the pointed head 11 is fixedly connected to the upper end of the sound-absorbing cotton 10. A plurality of pointed heads 11 are arranged, and are evenly distributed in a linear array on the upper end of the sound-absorbing cotton 10. By arranging the pointed heads 11 and the sound-absorbing cotton 10, noise can be weakened under the action of the pointed heads 11 and the sound-absorbing cotton 10 during operation.

[0028] A positioning groove 12 is provided on the lower end surface of the upper plate body 101, and a limiting frame 13 is slidably connected inside the positioning groove 12. The limiting frame 13 is fixedly connected to the lower plate body 102. By setting the positioning groove 12 and the limiting frame 13, during operation, the upper plate body 101 and the lower plate body 102 can be conveniently spliced ​​together under the action of the positioning groove 12 and the limiting frame 13.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
