Abstract

A garage top slab structure comprises an upper layer of top slab, ribbed beams and a lower layer of top slab sequentially from the top down, and inner concrete structure cavity membranes are placed in the closed cavities defined by the upper layer of top slab, the lower layer of top slab and the ribbed beams; each inner concrete structure cavity membrane comprises at least one inner membrane module, and an outer layer of fire-retardant coating and at least one PVC (polyvinyl chloride) fixing frame are arranged on the surface of the inner membrane module; and the inner membrane modules is aare flame-retardant solid polystyrene foam blocks, the density of which is greater than 15Kg / m<3>. The invention also discloses the inner concrete structure cavity membrane, which comprises at least one inner membrane module with the outer layer of fire-retardant coating at the outer surface and at least one PVC fixing frame arranged on the surface of the inner membrane module; and the inner membrane module is the flame-retardant solid polystyrene foam block, the density of which is greater than 15Kg / m<3>. A construction method for the garage top slab structure is characterized in that the construction method includes the following steps: (1) laying a bottom slab formwork; (2) determining the mounting positions of the inner membrane modules; (3) installing the inner membrane modules; (4) tying and fixing anti-floating reinforcements; (5) pouring concrete.

Description

technical field

[0001] The invention belongs to the technical field of garage roof structures, and specifically relates to the application technology of a solid polystyrene foam block in the concrete cavity structure of the garage roof. Background technique

[0002] At present, the concrete structure filling of the garage roof mostly uses cavity components, which are very easy to be damaged during the construction process and the existing filling components are too heavy. They need to be hoisted and transported during installation, which wastes mechanical labor and high construction costs. For example, 00113549.X is a reinforced concrete cast-in-place porous floor and its manufacturing method. It is characterized in that the manufactured cast-in-situ reinforced concrete porous floor contains cavities which are core-pulled to form holes. The production method is as follows: support the bottom formwork of the floor cover, and bind the steel bars; pre-embed the mandrel befo...
