Embodiment Construction

[0014] The lightweight floating floor of the present invention includes a sealant 3 , a vibration isolator 4 , a keel 5 , a sound insulation board 6 , a concrete base 7 and sound-absorbing cotton 8 . In the figure, 1 is the foundation (floor, ground, etc.), and 2 is the wall. Wherein the keel 5 is mostly made into a cross grid form, and can also be made into other forms according to actual requirements. Weld a steel plate on the lower surface of the keel that needs to place the fixed equipment, and pour concrete machine base 7 on this plate to ensure that it is fixed with the keel. Lay the sound insulation board 6 on the remaining keels, and fix the two, and also the sound insulation board 6 can be made into fritters and fixed on the keel respectively, which is conducive to maintenance and repair in the future. At an appropriate position of the keel 5 (usually at the intersection), it is connected with the foundation 1 through a vibration isolator 4 to provide support for the...

Abstract

The invention discloses a light-weight floating floor for controlling structure noise of fixing equipment and a use method thereof. A keel is used as a framework to manufacture the floating floor, a concrete machine seat is cast on the keel for containing the fixing equipment, the other keels are paved with a sound isolation plate, the floating floor is connected with a foundation through a vibration isolator, and then the structure noise of the fixing equipment is effectively controlled. The light-weight floating floor consists of the keel, the vibration isolator, the sound isolation plate, the concrete machine seat, sound absorbing asbestos and sealant, wherein the keel is used as the framework of the floating floor, the concrete machine seat is cast on the keel for containing the fixing equipment, the sound isolation plate can be manufactured into small blocks to be respectively and fixedly arranged on the keels, the upper and lower ends of the vibration isolator are respectively connected with the keel and the foundation, the support is provided for the keel, and the sound isolator can adopt the spring isolator, so as to obtain the vibration isolation effect. The sound absorbing asbestos is filled in the keel, and the sealant is filled among the keel, the sound isolation plate and the wall, so as to realize a better noise reducing effect.

Description

technical field [0001] The present invention relates to a light-duty floating floor, more specifically to a light-duty floating floor for controlling structural noise of fixed equipment and its application method. Background technique [0002] There are many types of fixed equipment in the building, which are widely used in various production and living facilities. At present, the fixed equipment used in large quantities at home and abroad generally has the problem of high noise, especially the structural noise is mostly low-frequency, propagates far, and is difficult to control, which has a negative impact on industrial production and the living environment. [0003] At present, the following types of measures are mainly taken to control the structural noise of fixed equipment in buildings. One is the use of vibration isolation technology for vibration isolation of fixed equipment, including two-stage, multi-stage vibration isolation, air spring vibration isolation, etc. ...
