Detailed Description

The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master.

The utility model discloses technical scheme is dedicated to and is improved among the super high-rise building and is born electromechanical device and produce a large amount of vibrations and noise influence all ring edge borders body and feel and user's comfort level when moving, and the innovation has reachd a floating platform for high-rise building.

Since the intermediate floors of the super high-rise building provided with the air-conditioning equipment rooms are usually planned at the beginning of building design, the number of modeling materials, specification thickness, maximum load strength and the like of the foundation structure floor corresponding to the floors are fixed. Therefore, the utility model discloses consider that the floating platform of design uses original structure floor to carry out the institutional advancement as the basis on the one hand, and the load weight that on the other hand increased satisfies the gross load that does not surpass original structure floor with electromechanical device's gross weight. As shown in fig. 1, the floating platform is characterized in that an elastic layer 2 and a floating layer 3 are sequentially laid on the basis of a structural floor slab 1, so that a flexible supporting structure with vibration energy absorption capability is formed. The elastic layer 2 is a flexible supporting layer formed by a rubber vibration isolation and sound insulation pad 21 and vibration isolation colloidal particles 22 embedded in the rubber vibration isolation and sound insulation pad, and mainly plays roles in energy absorption, conversion and dissipation; the floating layer 3 is a 100-thick cast-in-situ reinforced concrete slab laid on the surface of the elastic layer and mainly plays a supporting role; and a guide wall 4 is built on the structural floor around the elastic layer and the floating layer.

In more detail, the rubber anti-vibration sound insulation plate 5 and the encapsulated waterproof silica gel are arranged at the gap between the elastic layer and the floating layer on the inner side of the guide wall 4, so that the transverse diffusion of vibration is guaranteed to be transmitted to the original structural floor through the guide wall.

The elastic layer 2 needs to ensure the structural strength thereof at the same time, thereby ensuring the stability of the moving load. Therefore, the 1:3 cement mortar layer and the polyurethane waterproof coating are integrally and compositely pre-laid at the bottom of the elastic layer. This process is a common practice in the construction industry, and therefore the details of its construction thickness and other specifications are omitted.

The electromechanical equipment which correspondingly operates and vibrates on the surface of the floating layer 3 is also built and connected with an inertia base 6 and a spring shock absorber 7. This inertia base mainly used simulate former structure floor and increase thickness and connect etc. in order to do benefit to electromechanical device's drilling, and adjustable spring shock absorber is convenient for adjust damping performance according to the intensity change of equipment dead weight and during operation load, and bigger can also choose for use damping spring damping device to replace certainly.

The manufacturing method of the floating platform is understood from field construction, the construction scene is the structural floor slab corresponding to the floor blank, and the specific operation steps are developed as follows.

S1, budgeting and material preparing, firstly, calculating the static load of the floating platform according to the field use requirement, then calculating the live load of the floating platform according to the technical parameters of equipment operation, and adding the static load and the live load to obtain the total load. Then, the total number of the vibration isolation rubber particles required for isolation is calculated according to the maximum allowable load of each square of the vibration isolation rubber particles, and finally the arrangement intervals of the vibration isolation rubber particles are designed according to the area of the floating platform and the number of the rubber particles.

S2, building a guide wall according with the electromechanical equipment bearing range on the basis of the structural floor slab to enclose into a closed shape, and connecting an FCD type lateral special rubber vibration-proof sound-proof board on the inner side of the guide wall, wherein specification parameters can be selected to be 145mm high and 20mm thick, and the length can be freely customized according to the actual circumference of the floating platform.

Wherein, a conventional horizontal pouring process is adopted before the leveling layer, then the laid vibration isolation and sound insulation pad is used as a foundation for bottoming to serve as a transition connection layer, and the floating structure on the surface is the elastic support layer which is formed by gradually building according to the vibration isolation rubber particle amount and the arrangement interval calculated in the step S1. And the last top waterproof coating is used as the transition of the floating layer, so that the effect of protecting the vibration isolation and sound insulation material is achieved to a certain extent.

S4, laying 100 thick cast-in-situ reinforced concrete plates on the surface of the top waterproof coating to form a floating floor, and simulating the original structural floor with a full-rigid surface to provide horizontal connection of large electromechanical equipment. After the surface and the inner lining are completely solidified, an inertia base can be further built, and then auxiliary mounting facilities and tools such as a spring damper and the like are positioned and mounted.
