Cast-in-place concrete floor slab structure

Abstract

The invention provides a cast-in-place concrete floor slab structure. The cast-in-place concrete floor slab structure includes a splicing frame, the two ends of the splicing frame are fixed to a fixing frame, a material feeding inlet is arranged at one end of the fixing frame in a penetrating mode, an air outlet is formed in one side of the material feeding inlet, a limiting groove is arranged at one end of the air outlet in a penetrating mode, a hollow cylinder is arranged at one end of the limiting groove in a penetrating mode, a water outlet pipe is arranged on one side of the hollow cylinder in a penetrating mode, a water storage groove is arranged on one side of the water outlet pipe in a penetrating mode, the inner part of the hollow cylinder is movably connected with an extracting plate in an embedded and sleeving mode, a sliding frame slides on one end of the extracting plate, the upper end of the splicing frame is embedded with a groove, by arranging the hollow cylinder, the temperature of concrete rises due to the fact that hydration reaction occurs in the inner part of the concrete, through the principle of expansion and contraction, the volume of the concrete is expanded slightly, when the concrete expands, the concrete squeezes the sliding frame which moves in the vertical direction, and when the sliding frame moves, the extracting plate is driven to squeeze the air in the inner part of the hollow cylinder.

Description

technical field [0001] The invention belongs to the technical field of buildings, in particular to a cast-in-place concrete floor structure. Background technique [0002] Cast-in-place refers to setting up the formwork on site, installing steel bars on the formwork, pouring concrete on the formwork, and then removing the formwork. Compared with prefabricated floors, the cast-in-place layer can enhance the integrity and earthquake resistance of the house. Larger bearing capacity, but also has certain advantages in heat insulation, sound insulation, waterproof and so on. [0003] For example, the patent whose application number is CN200810082642.5 discloses a cast-in-place reinforced concrete slab, including reinforced concrete and components for forming holes. There are connecting parts for combination, the combination parts have grooves, and stiffeners are arranged at the groove positions, so that it is suitable for use in various cast-in-place concrete hollow floors, roofs...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a cast-in-place concrete floor structure to solve the problem that a large amount of concrete needs to be poured when the existing cast-in-place concrete floor structure is being constructed, and the concrete is usually thicker after pouring, and the concrete The interior contains a lot of water, which makes the existing concrete take a lot of time to dry during pouring, and the existing cast-in-place concrete floor structure cannot assist the concrete to dry quickly, so that the construction time of the existing cast-in-place concrete floor is longer, and Because the connection between the concrete floor structure and the concrete is a joint connection, the stability between the existing concrete floor structure and the concrete is poor, and the problem that the concrete cannot be assisted in forming
