Embodiment

[0033] The high-efficiency damping type composite floor structure in the present invention comprises a fiber cement board 1, a plurality of I-shaped steel beams 2, a concrete layer 3 and a composite damping layer 4, see figure 1 .

[0034] The I-shaped steel beam 2 is arranged on the fiber cement board 1, and the I-shaped steel beam 2 is provided with a plurality of damping strip tubes 5, see figure 2 and image 3 , the height of the I-shaped steel beam 2 is 5~15cm during concrete implementation.

[0035] The concrete layer 3 is filled on both sides of the I-shaped steel beam 2, so that the concrete layer 3 and the I-shaped steel beam 2 together form a layer structure, which is actually a layer structure with a rectangular cross section.

[0036] The damping strip tube 5 is fixed on the waist 22 of the I-shaped steel beam, and the high-efficiency energy-consuming I-steel structure is constructed through the cooperation of the damping strip tube 5 and the I-shaped steel, so ...

Abstract

The invention relates to an efficient damping type composite floor structure which comprises a fiber cement board, a plurality of I-shaped steel beams, a concrete layer and a composite damping layer, the I-shaped steel beams are arranged on the fiber cement board, and a plurality of damping strip pipes are arranged on the I-shaped steel beams; the two sides of the I-shaped steel beams are filled with the concrete layers, so that the concrete layers and the I-shaped steel beams jointly form a layer structure. The composite damping layer is arranged above the concrete layer and the I-shaped steel beam and comprises an internal metal-nonmetal damping layer and a polyurethane damping layer wrapping the metal-nonmetal damping layer. Compared with the prior art, the efficient energy consumption type I-shaped steel structure is constructed through cooperation of the damping strip pipes and the I-shaped steel, so that vibration energy transmitted in the vertical direction of the I-shaped steel is obviously consumed; and meanwhile, step-by-step energy consumption is achieved through a metal-nonmetal damping layer in the composite damping layer, and dissipation of edge and surface vibration is achieved in cooperation with an energy dissipation structure of the polyurethane damping layer.

Description

technical field [0001] The invention relates to the field of building structures, in particular to an efficient damping composite floor structure. Background technique [0002] The damping floor structure is widely used in architectural scenes that have a strong demand for sound insulation and noise reduction, such as sports venues, multi-functional office buildings, shopping malls, indoor playgrounds, etc. All of the above scenes may generate large vibration and noise, which will wear It is transmitted to other floors through the floor, causing strong noise and vibration interference in other floors. [0003] Most of the existing sound insulation measures are directly laying polymer sound insulation mats. This method is not effective and the sound insulation mats have been damaged. Other measures are to use concrete doped with polymer materials for active noise reduction, but it can only consume 20% of the noise. left and right vibrational energy. [0004] CN110616836A di...
