Problems solved by technology

[0005] In view of the problem that in the air layer of the existing double-layer hollow floor, part of the formwork is closed inside and cannot be taken out, resulting in a reduction in the sound insulation and noise reduction performance of the double-layer hollow floor, the purpose of the present invention is to provide a double-layer hollow sound insulation The concrete slab and its construction method use the prefabricated slab to close the top of the cavity, and use the prefabricated slab as the pouring bottom form of the upper floor, which eliminates the work of removing the bottom form and avoids objects that may cause solid sound transmission to be left in the cavity. Eliminate the sound bridge that can transmit sound to ensure the sound insulation and noise reduction effect of the concrete slab

Embodiment 1

[0025] Example 1: Combining Figure 4 Describe the double-layer hollow sound-insulating concrete slab of this embodiment. This embodiment takes the structure of the floor as an example. It includes two parallel and spaced bottom plates, which are respectively the lower floor 1 and the upper floor 6; the lower floor 1 and the upper floor At least two beams 2 are arranged at intervals between 6, the beams 2 are all perpendicular to the lower floor 1, and two adjacent beams 2 are arranged in parallel, the lower floor 1, the upper floor 6 and the beam 2 form a plurality of cavities 4; it also includes The prefabricated slabs 5 arranged in sequence and overlapped between two adjacent beams 2 can close the top of the cavity 4 , and the prefabricated slabs 5 and the upper floor 6 are integrated.

Embodiment 2

[0028] Embodiment 2: Combination Figure 7 Explain that the double-layer hollow sound-insulating concrete slab of this embodiment is different from the first embodiment in that notches 3' are provided on both sides of the top of the beam 2, and the prefabricated slabs 5' are arranged in sequence and placed between two adjacent beams 2 notch 3' and closes the top of the cavity 4'. In this embodiment, the notch 3' provided on the beam 2 is used to support the prefabricated slab 5', which saves the construction work of the corbel and makes the operation easier.

Embodiment 3

[0029] Example Three: Combining Figure 1 to Figure 4 Describe the construction method of the double-layer hollow sound-insulating concrete slab of the present embodiment, and the present embodiment takes the construction of the floor slab as an example, figure 1 and figure 2 The dotted line in the middle indicates the location of the lower surface of the upper floor, and the specific construction steps are as follows:

[0030] S301: Prepare the prefabricated slab 5, so that the length of the prefabricated slab 5 is not less than the shortest distance between the corbels 3 on two adjacent beams 2;

[0031] S302: if figure 1As shown, the formwork is erected, the lower floor 1 and the crossbeam 2 perpendicular to the lower floor 1 are poured, and the embedded parts (not shown) are set on the side of the top of the crossbeam 2 (not shown in the figure), the thick solid line in the figure represents the steel formwork;

[0032] S303: if figure 2 As shown, remove the formwor...

Abstract

The invention provides a double-layer hollow sound insulation concrete slab and a construction method thereof, relates to the technical field of concrete members and aims at solving the problem of degradation of sound insulation and noise reduction performance of a double-layer hollow floor slab due to the fact that some templates are enclosed in and cannot be removed out of an air layer of an existing double-layer hollow floor slab. The double-layer hollow sound insulation concrete slab comprises two parallel and spaced base plates, at least two beams spaced between the two base plates, and a prefabricated panel which is arranged at one end of each of the beams, overlapped between the adjacent two beams and made with the adjacent base plate into a whole. The construction method includes the steps of 1 manufacturing a prefabricated panel; 2 pouring the base plate at a lower layer and the beams; 3 removing templates of the base plate at a lower layer and the beams, overlapping the prefabricated panel between the adjacent two beams, and closing a cavity between the adjacent two beams; 4 pouring concrete to the prefabricated panel as a bottom mold of the base plate at a higher layer to obtain the double-layer hollow sound insulation concrete slab.

Description

technical field [0001] The invention relates to the technical field of concrete components, in particular to a double-layer hollow sound-insulating concrete slab and a construction method thereof. Background technique [0002] With the rapid development of urban construction and the improvement of people's quality of life, creating a high-quality living environment has become an urgent desire of people. Among them, a good indoor acoustic environment is an important part of ensuring a high-quality living environment. [0003] Since floor sound transmission is one of the most important sources of indoor noise, how to improve the sound insulation and noise reduction performance of floors has been a problem that people have been constantly exploring. In the current building construction technology, the sound insulation and noise reduction of buildings is mostly started from the perspective of building materials and decoration. The specific measures mainly include the following p...
