Embodiment 1

[0041] like Figure 1-3 shown.

[0042] A cast-in-place reinforced concrete hollow floor (slab) with thermal insulation and sound insulation functions, which is formed by pouring concrete and steel bars. The steel bars are composed of upper steel mesh and lower steel mesh. The formed grid-like space is filled with spherical heat-insulating and sound-insulating material bodies, and the diameter of the spherical heat-insulating and sound-insulating material body is smaller than the size of the grid formed by binding the upper and lower steel bars vertically and horizontally. 10-30% of the volume of the whole floor (slab). The insulation compartment material body is one or a combination of foamed plastics such as foamed polyurethane and foamed polyethylene. The material body of the thermal insulation compartment is light in weight, and its density is much lower than that of concrete.

Embodiment 2

[0044] like Figure 1-3 shown.

[0045] A cast-in-place reinforced concrete floor (slab) with thermal insulation and sound insulation functions is prepared through the following steps:

[0046] 1. According to the design requirements, select appropriate steel bars in the vertical and horizontal directions, and bind the lower steel bars of the concrete floor (slab) at a certain interval.

[0047] 2. The diameter of the filler sphere is determined according to the thickness of the final formed floor (slab), and the diameter is preferably changed according to the thickness of the concrete floor (slab), which is conducive to maintaining the concrete floor (slab) while maintaining heat insulation and sound insulation and reducing its own weight. rigidity.

[0048] 3. After determining the diameter of the filler material, determine the spacing of the auxiliary reinforcement according to the diameter of the filler sphere. The auxiliary reinforcement is two thin steel bars placed ...

Abstract

The invention relates to a cast-in-place reinforced concrete hollow floor (plate) with both thermal insulation and sound insulation functions and a preparation method thereof. The hollow floor is prepared by concrete and a reinforcing steel bar poured together and is characterized in that the reinforcing steel bar consists of an upper layer of bar-mat reinforcement and a lower layer of bar-mat reinforcement; a grid space formed by a upper layer of reinforcing steel bar and a lower layer of reinforcing steel bar is filled with a spherical thermal insulation acoustic insulating material body; the diameter of the spherical thermal insulation acoustic insulating material body is less than the dimension of the grid formed by the upper layer of reinforcing steel bar and the lower layer of reinforcing steel bar that are bound horizontally and longitudinally; and the size of the spherical thermal insulation acoustic insulating material body accounts for 10-30% of the size of the grid space formed by the upper and the lower layers of reinforcing steel bars in longitudinal and horizontal directions. The thermal insulation material filled in the reinforced concrete hollow floor (plate) can improve the thermal insulation property of the reinforced concrete hollow floor (plate) and meanwhile, block up sound with certain wavelength from spreading, functioning in sound insulation. When being used for unidirectional and bidirectional load, the hollow floor has good bearing capacity.

Description

technical field [0001] The invention relates to a building structure, especially a building floor (slab) and a preparation method thereof, in particular to a cast-in-place reinforced concrete hollow floor (slab) with thermal insulation and sound insulation functions and a preparation method thereof . Background technique [0002] In order to meet the needs of multi-functional, multi-purpose, large column nets, and large bays in modern buildings, the reinforced concrete floor structure has been continuously improved, and new structural forms are constantly emerging. The emergence and application of reinforced concrete hollow floors began in the 1990s. With the continuous development and improvement of internal mold technology, the development of hollow floors (slabs) is very rapid. Space requirements, but also has good structural performance, suitable for a variety of structural forms, especially multi-storey and high-rise buildings with large spans and large spaces, and has...
