Novel prefabricated heat preservation and sound insulation floor structure and construction method thereof

Abstract

The invention discloses a novel prefabricated heat preservation and sound insulation floor structure and a construction method thereof. A prefabricated heat preservation and sound insulation floor comprises upper and lower layers of reinforced concrete prefabricated plates and a heat preservation and sound insulation plate. The heat preservation and sound insulation plate is located between the upper and lower layers of reinforced concrete prefabricated plates. The prefabricated heat preservation and sound insulation floor structure is fixedly connected with a cast-in-situ frame beam structure in a cast-in-situ mode to form an integral type frame beam-plate concrete structure. The novel prefabricated heat preservation and sound insulation floor structure can form the integral frame structure with a cast-in-situ frame beam, so that the force bearing requirement is met, and the construction procedures and the construction period are reduced, and meanwhile the heat preservation and sound insulation effects can be also met; and a T-shaped beam member serves as the cast-in-situ frame beam, and a galvanized water stopping steel plate is arranged on the surface of the T-shaped beam member, so that the water seepage prevention property of the junction surface of the prefabricated heat preservation and sound insulation floor and the cast-in-situ frame beam is improved by a large margin.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a novel prefabricated thermal insulation and sound insulation floor structure and a construction method thereof. Background technique [0002] The traditional concrete frame beam and slab structure generally adopts the form of cast-in-place construction, and it is necessary to pre-support the formwork and the steel bar binding construction before proceeding to the overall pouring construction of the concrete structure. However, since the cast-in-place slab structure has only one concrete slab, the thermal insulation and sound insulation effects are poor, and the thermal insulation and sound insulation layers need to be reapplied during later construction and decoration. Not only is the construction process complicated, the construction period is long, and the cost is high. Contents of the invention [0003] The purpose of the present invention is to overcome the defects ...
