AI Technical Summary

Technical Problem

The existing semi-prefabricated floor slabs require a lot of labor to rotate bolts during splicing and assembly, resulting in low assembly efficiency and affecting the construction progress.

Method used

The design incorporates a combination of a first floor slab main body, a second floor slab main body, an I-shaped limiting frame, a lever plate, a guide groove, a guide block, a straight rod, a protective groove, a pressure plate, an insert rod, a guide rod, a spring, a limiting groove, and a positioning socket. The I-shaped limiting frame is inserted into the limiting groove, and the spring's elasticity allows the insert rod to be inserted into the positioning socket, achieving rapid fixation.

Benefits of technology

It improved the assembly efficiency of floor slabs, accelerated the construction progress, and enhanced the strength of the poured concrete through steel trusses.

Abstract

The utility model relates to the technical field of fabricated building, and disclose a floor slab for fabricated building, including one floor slab main part and two floor slab main part, the right side of one floor slab main part is overlapped in the left side of two floor slab main part, the both sides of one floor slab main part and two floor slab main part all are provided with the limiting recess, be equipped with the limit frame of I -beam between one floor slab main part and two floor slab main part. The utility model discloses the limit recess inside between one floor slab main part and two floor slab main part is inserted to the limit frame of I -beam, thereby can carry out the limiting fixing between one floor slab main part and two floor slab main part, and the spring resilience can make the one end of the insertion rod insert the inside of the positioning spout, thereby carry out the limiting fixing to the limit frame of I -beam, adopt this kind of mode to be convenient for the fixed assembly between two floor slabs fast, improve the assembly efficiency, speed up the construction progress.
