Further, described spherical main top and bottom are provided with groove, and described groove is between the two panels plastics clamping sheet of reinforcing bar holder, and depth of groove is 13 ~ 15mm.
Further, the pin number bottom described reinforcing bar holder is 2 to 4.
Beneficial effect: a kind of steel concrete sound-absorbing hollow floor cover plate of the present utility model, mainly comprise upper and lower two layers of mesh trellis cage of reinforcement and the some baton round assemblies between upper and lower two layers of mesh trellis cage of reinforcement, be filled with damping material in baton round assembly, for the sound wave clashing into floor structure generation, there is sound-absorbing effect.A reinforcing bar holder is all provided with at the upper and lower two ends of hollow plastic ball, the steel bar clamping ring formed by reinforcing bar holder Elastic reed clamps upper and lower two-layer netted cage of reinforcement, namely upper and lower two-layer netted cage of reinforcement is fixed by baton round assembly, baton round assembly is made not only to play sound absorption in sound-absorbing hollow floor cover plate, can also play integrally-built fixation, the Stability Analysis of Structures when concreting.Because upper and lower two-layer netted cage of reinforcement is fixed into entirety by baton round assembly, the thickness of whole hollow floor cover plate after can effectively controlling concreting by the size designing hollow plastic spheres and reinforcing bar holder.Reinforcing bar holder is mated with the circular hole at the upper and lower two ends of hollow plastic ball by the pin bottom it and is connected.One end of pin is folded fundus gallbladder, the diameter at folded fundus gallbladder largest circumference place is greater than the Circularhole diameter 0.8 ~ 1.2mm on hollow plastic ball, the benefit of such setting is because spherical main is plastic products, it has certain elasticity, pin with folded fundus gallbladder, than the circular hole being easier to be embedded on hollow plastic ball, assembles very convenient.Such structure is also conducive to separately preparing whole spherical main and reinforcing bar holder, reduces the difficulty of preparation technology, improves yield rate.Between the two panels plastics clamping sheet of reinforcing bar holder, groove is set, when the reinforcing bar one of latticed cage of reinforcement right-angled intersection place is on another root, when reinforcing bar holder clamping be the reinforcing bar on upper strata time, lower floor's reinforcing bar is just in time placed in groove, thus avoids lower floor's reinforcing bar to the extruding of plastic sphere.

Detailed description of the invention
Below in conjunction with accompanying drawing the utility model done and further explain.
As shown in Figure 1, a kind of steel concrete sound-absorbing hollow floor cover plate, comprises upper and lower two layers of mesh trellis cage of reinforcement, and connects some baton round assemblies of upper and lower two layers of mesh trellis cage of reinforcement.Each baton round assembly comprises spherical main and lays respectively at the reinforcing bar holder of spherical main top and bottom.Wherein, as in Figure 2-4, spherical main is hollow plastic spheres, and the hollow plastic spheres of spherical main to be radius be 50 ~ 60mm, inside is pre-charged with damping material, as Bath sound-absorbing foam.Be fastenedly connected by public rod and mortise between adjacent plastic sphere, between plastic sphere, form connecting pipe.
The reinforcing bar holder of spherical main top and bottom is symmetrical about the horizontal central plane of hollow plastic spheres.Reinforcing bar holder comprises symmetrically arranged two panels plastics clamping sheet 1, and every sheet plastics clamping sheet 1 comprises the arc-shaped elastic reed 12 being positioned at the symmetrically arranged bearing 11 in outside and being positioned at inside bearing.Holder top funnel, fixes in the middle part of the top of elastic spring 12 and bearing, and the lower end of elastic spring 12 freely.Reinforcing bar holder whole height is 32 ~ 42mm, and two arc-shaped elastic reeds 12 of every sheet plastics clamping sheet 1 form steel bar clamping ring, and the vertical distance of steel bar clamping Ring current distribution and rest base is 9 ~ 13mm.Steel bar clamping ring clamps upper and lower two layers of mesh trellis cage of reinforcement.In the present embodiment, the thickness of plastics clamping sheet 12 can be set to 5mm, and holder top funnel opening can be set to 14mm.Reinforcing bar holder is connected with spherical main by bottom pin 2.Spherical main top and bottom are provided with groove 3, and groove 3 is between the two panels plastics clamping sheet 1 of reinforcing bar holder, and groove 3 degree of depth is 13 ~ 15mm.
As shown in Figure 5,6, reinforcing bar holder connects spherical main by pin 2, and one end of pin is fixed on the bottom of reinforcing bar holder, and the other end of pin is folded fundus gallbladder 21.Top and the bottom of spherical main are provided with circular hole, and always, its diameter can be 5mm for Circularhole diameter and pin main diameter.The diameter at folded fundus gallbladder 21 largest circumference place is greater than described Circularhole diameter 0.8 ~ 1.2mm.Pin number bottom reinforcing bar holder is 2 to 4, arranges a pin, or two pins are disposed on two ends bottom every sheet plastics clamping sheet 1 in the middle of namely bottom every sheet plastics clamping sheet 1.
In addition, in order to when later stage concreting, cause overall structure relative to the slip of levels steel mesh reinforcement structure in order to reduce concrete to the impact of baton round assembly, in the present embodiment, the plastics clamping sheet of upper and lower reinforcing bar holder stamps through hole 13, thus reducing when concreting, concrete lifting surface area is moved in the convection current of reinforcing bar holder.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
