Embodiment Construction
[0014] The present invention will be further explained below in conjunction with the accompanying drawings.
[0015] Such as figure 1 As shown, a reinforced concrete sound-absorbing hollow floor slab includes an upper and lower two-layer grid-like steel skeleton, and several plastic ball components connecting the upper and lower two-layer grid-like steel skeleton. Each plastic ball assembly includes a spherical main body and steel bar clip seats respectively located at the top and bottom of the spherical main body. Among them, such as Figure 2-4 As shown, the spherical body is a hollow plastic sphere, and the spherical body is a hollow plastic sphere with a radius of 50-60 mm, and the interior is pre-filled with sound-absorbing materials, such as Bath sound-absorbing foam. Adjacent plastic spheres are tightly connected by male rods and mortise holes, and connecting pipes are formed between the plastic spheres.
[0016] The steel bar holders at the top and bottom of the sph...

Abstract
The invention relates to a reinforced concrete sound-absorption hollow floor slab. The reinforced concrete sound-absorption hollow floor slab mainly comprises an upper layer latticed steel reinforcement framework, a lower layer latticed steel reinforcement framework, and a plurality of plastic ball assemblies positioned between the upper layer and the lower layer of latticed steel reinforcement frameworks; the plastic ball assemblies are filled with a sound absorption material which has a sound absorption effect on sound waves generated by impacting the floor slab. A steel reinforcement clamping holder is arranged on the upper end and the lower end of each hollow plastic ball respectively; the upper layer and the lower layer of latticed steel reinforcement frameworks are clamped by steel reinforcement clamping rings formed by elastic reeds in the steel reinforcement clamping holders, namely the upper layer and the lower layer of latticed steel reinforcement frameworks are fixed by the plastic ball assemblies, so that the plastic ball assemblies not only play a sound absorption role in the sound-absorption hollow floor slab, but also play a fixing role in the integral structure, and the structure is stable in the concrete pouring process. Since the upper layer and the lower layer of the latticed steel reinforcement frameworks are fixed into a whole through the plastic ball assemblies, the thickness of the whole hollow floor slab after concrete pouring can be effectively controlled by designing the sizes of the hollow plastic ball bodies and the steel reinforcement clamping holders.
Description
technical field [0001] The invention relates to a reinforced concrete sound-absorbing hollow floor slab. Background technique [0002] At present, the floor slabs in buildings are mostly reinforced concrete floor slabs, which are solid structures made of concrete and steel bars. This kind of floor slab is strong, durable, high in rigidity, high in strength, and good in fire resistance, and is currently widely used. According to the construction method, it can be divided into two categories: cast-in-place reinforced concrete floor slab and fabricated reinforced concrete floor slab. The construction process of cast-in-place reinforced concrete slabs includes steps such as setting out wires, forming and erecting formwork, making and binding steel bars, pouring concrete, and removing formwork. The cast-in-place reinforced concrete floor is a solid structure, and the noise generated by the impact force acting on it is unavoidable. Contents of the invention [0003] Purpose o...
