Embodiment Construction

[0029] see figure 1 , in this embodiment, the cast-in-place floor slab is set, which is a box-shaped body with hollow cavities composed of ring beam 1, cover plate 2 and bottom plate 3. The hollow cavities are independently arranged in a matrix, and adjacent hollow cavities are connected in The support ribs 4 between the cover plate 2 and the bottom plate 3, the support ribs 4 are in a cross array;

[0030] figure 1 , figure 2 and image 3 As shown, the floor sound insulation core material 5 is set in the hollow cavity, the floor sound insulation core material 5 is a lightweight elastic embedded part, and the hollow cavity uses the pre-embedded floor sound insulation core material 5 as the forming mold; the ring beam 1 and the support rib 4 The sound insulation layer 6 is set on any plane at the position.

[0031] In the specific implementation, the volume of the sound-insulating core material 5 of the floor slab accounts for 26-55% of the volume of the cast-in-place floo...

Abstract

The present invention relates to a cast-in-place reinforced concrete sound-insulating floor slab and its construction method. It is characterized by setting box-form body cast-in-place floor slab which is formed from ring beam, cover slab and base slab and has hollow cavities, said hollow cavities are respectively independent and formed into matrix-type arrangement, between two adjacent hollow cavities the supporting ribs are set, and connected between the cover slab and base slab, said supporting ribs are formed into a cross array; setting floor slab sound-insulating core material, it is light elastic embedded component, the hollow cavity utilizes the embedded floor slab sound-insulating core material as forming mould; at the same time setting sound-insulating layer.

Description

Technical field: [0001] The invention relates to a cast-in-place reinforced concrete soundproof floor slab and a construction method thereof. Background technique: [0002] At present, the weighted impact sound pressure level of ordinary 10-12 cm thick cast-in-place concrete floor slabs widely used is 80-82dB, and the weighted impact sound pressure level of ideal residential floor slabs should be less than 65dB. The problem of sound insulation on the floor is serious, and many residents have complained. [0003] In modern building construction, the way of known floor sound insulation and thermal insulation technology adopted is to spread a layer of sound insulation pad and thermal insulation material on the finished cast-in-place reinforced concrete floor slab, and then pour 4-10 cm on it. This method increases the weight of the floor slab and increases the cost very much, and makes the floor slab unable to form an overall structure, and cannot achieve the effect of interlo...
