Description
Technical Field
The utility model relates to a building engineering technical field especially relates to a prefabricated floor exempts from to support connection structure of construction.
Background
With the national emphasis on energy conservation and emission reduction of building engineering, the assembly type building is more and more widely applied. Among them, the prefabricated floor slab is most widely used.
When traditional precast floor slab construction need set up scaffold frame or support at the bottom of the board, and the efficiency of construction is low, with high costs. For assembling a precast floor slab without a support and with less support at the slab bottom, the following connection structure is often used. As shown in fig. 1-2, the connecting structure includes a prefabricated floor slab 1 and two adjacent prefabricated supporting bodies 2, the prefabricated supporting bodies 2 can be prefabricated supporting walls or prefabricated supporting beams, the side surfaces of the two prefabricated supporting bodies 2 close to each other are both provided with a lifting lug 7 as a support of the prefabricated floor slab, and the upper end surface of the lifting lug 7 is flush with the upper end surface of the prefabricated supporting body 2; the prefabricated floor slab 1 is arranged at the upper ends of the two adjacent cantilever lugs 7; casting a cast-in-place support body 5 on the prefabricated support body 2; and a cast-in-situ floor 6 is poured at the top end of the prefabricated floor 1.
No matter this support is cast in situ or prefabricated, all consume manual work and material comparatively. In addition, the ear is chosen to have certain thickness, often influences net height and architectural effect.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prefabricated floor exempts from to support connection structure of construction to solve above-mentioned technical problem.
In order to achieve the purpose, the support-free construction connection structure for the prefabricated floor slab comprises the prefabricated floor slab and two adjacent prefabricated support bodies, wherein the prefabricated support bodies can be prefabricated support walls or prefabricated support beams, and the side surfaces, close to each other, of the two prefabricated support bodies are provided with angle steels; the side surface of the angle steel is welded with an anchoring steel bar; embedding the anchoring steel bars into the prefabricated support body; the top surfaces of the angle steels are flush with the top surface of the prefabricated support body; the prefabricated floor slab is placed on the top surfaces of the two adjacent angle steels.
Further, casting a cast-in-place support body on the prefabricated support body; and pouring a cast-in-place floor slab on the top end of the prefabricated floor slab.
Has the beneficial effects that: the utility model discloses a prefabricated floor exempts from to support connection structure construction of construction more convenient, the architectural effect is good.
