Through bar type concrete composite floor slab structure and manufacturing and assembling method thereof

Abstract

The invention relates to the field of assembled concrete buildings, in particular to a through bar type concrete composite floor slab structure and a manufacturing and assembling method thereof. The structure comprises prefabricated base plates, longitudinal stressed steel bars, reserved transverse stressed steel bar grooves, hogging moment steel bars, transverse stressed steel bars and the like. Due to the fact that transverse stressed steel bars of the unique prefabricated base plates are continuous, additional connecting measures and additional connecting steel bars are not needed for connection of the prefabricated base plates, construction is simplified, materials are saved, and the integrity of composite slabs is greatly strengthened. The reserved transverse stressed steel bar grooves of the through bar type concrete composite floor slabs reinforce shear resisting and tensile resisting connection of a cast-in-place concrete layer and the prefabricated base plates, and the overall performance of the composite slabs is greatly improved. The transverse stressed steel bars of the through bar type concrete composite floor slab structure are placed in the reserved transverse stressed steel bar grooves formed in the prefabricated base plates, maximum approximating to the prefabricated base plates is achieved, and the anti-bending stress performance of the prefabricated base plates can be same as the performance of cast-in-place slabs.

Description

technical field [0001] The invention relates to the field of prefabricated concrete buildings, in particular to a reinforced concrete laminated floor structure and a manufacturing and assembling method thereof. The produced reinforced concrete laminated floor can be used as a floor used in prefabricated concrete buildings. Background technique [0002] In prefabricated concrete buildings, floor slabs are generally made of concrete laminated slabs. There are many forms of concrete laminated slabs, including prestressed concrete sandwich laminated slabs, concrete laminated slabs with reverse ribs, ordinary prestressed concrete hollow laminated slabs, self-supporting reinforced concrete laminated slabs, and concrete laminated slabs with shear keys Wait. For these laminated slabs, because the transverse stress reinforcement of the precast concrete floor is cut off at the edge of the precast floor, measures such as adding additional steel bars are required for the connection bet...

AI Technical Summary

Problems solved by technology

For these laminated slabs, because the transverse stress reinforcement of the precast concrete floor is cut off at the edge of the precast floor, measures such as adding additional steel bars are required for the connection between the precast concrete floor, which increases the complexity of the construction and the amount of reinforcement. The discontinuity of the reinforced steel bars also has an adverse effect on the stress of the overall concrete laminated slab
