Problems solved by technology

[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.

Embodiment 1

[0040] Such as image 3 As shown, a cavity inner membrane of a concrete structure comprises at least one inner membrane component 2, an outer fireproof coating is arranged on the surface of the inner membrane component 2, and at least one PVC fixed outer frame 6; the inner membrane component 2 is Density greater than 15Kg / m 3 Flame retardant solid polystyrene foam block. There are two inner membrane components 2, and two PVC fixed outer frames 6. Each PVC fixed outer frame 6 has a rectangular baffle 5 on one side, and the baffle 5 is 10 cm wide to ensure that the inner membrane components 2 are installed with a distance of 10 cm between them, and horizontal displacement will not occur during the construction process; Figure 5 As shown, the top of the inner membrane component 2 is laid with two anti-floating steel bars 7 that are firmly overlapped with the densely ribbed beam 4. The anti-floating steel bars are two secondary threaded steel bars with a diameter of not less t...

Embodiment 2

[0042] The similarities between this embodiment and Embodiment 1 will not be repeated, and the difference is that it is a garage roof structure using a concrete structure cavity inner membrane, such as Figure 1-2 As shown, it includes from top to bottom the upper roof 1, the densely ribbed beam 4 and the lower roof 3, all of which are reinforced concrete structures. Concrete structure cavity inner membrane; said concrete structure cavity inner membrane, which includes at least one inner membrane component 2, an outer layer of fireproof coating is arranged on the surface of the inner membrane component 2, and at least one PVC fixed outer frame 6; said inner Membrane module 2 has a density greater than 15Kg / m 3 Flame-retardant solid polystyrene foam blocks to ensure the thickness of the concrete protective layer; the arrangement of the ribbed beams corresponding to the inner membrane components is a continuous well-shaped arrangement of 1000×1000mm and 1000mm×800mm.

Embodiment 3

[0044] Such as Figure 4 Shown, a kind of garage roof structure construction method, it comprises the steps:

[0045] 1. Lay the base plate formwork;

[0046] 1) The formwork and support system should be designed and calculated according to the actual load and construction height, and the inner membrane load can be ignored;

[0047] 2) The bottom formwork is fully laid, and the formwork should be arched according to the design requirements when supporting the formwork, and the formwork at the post-pouring belt should be laid separately;

[0048] 2. Determine the installation position of the inner membrane; determine the installation position of the inner membrane after the bottom plate and the rib beam steel bars are bound, and pop up the edge of the rib beam, which is the position line of the outer edge of the inner membrane, according to the axis size of the construction drawing, so as to ensure the accurate positioning of the inner membrane; The total size of the engineer...

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...
