A method for manufacturing ultra-thin and light-weight jump floor slabs

Abstract

The invention provides a method for manufacturing ultrathin light duplex floor slabs. The technical scheme includes that the method comprises (1), manufacturing frames of the duplex floor slabs; (2), welding angle steel to form outer frames of the frames; (3), welding a steel grid on a bottom surface of each outer frame when the angle steel is welded; (4), welding transverse prismatic steel, longitudinal prismatic steel and oblique prismatic steel on the outer frames to form the transverse grids; (5), welding two pieces of arched round twisted steel on the outer surface of each outer frame and welding the round twisted steel on the outer frames by steel plates; (6), respectively welding two ends of each piece of round twisted steel at two short edges of the corresponding outer frame and enabling the distances from weld points to the long edges of the outer frames to be equal to one-fifth of the lengths of the short edges of the outer frames; (7), injecting cement mortar into the frames and compressing stone into the cement mortar. The method has the advantages that the duplex floor slabs manufactured by the aid of the method are thin and accordingly only occupy small spaces, and the heights of floors can be increased; the duplex floor slabs are tough and are high in load capacity and free of deformation, and the duplex load-bearing requirements can be met.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a method for manufacturing a floor slab, in particular to a method for manufacturing a jump floor suitable for jumping floors. Background technique [0002] In the existing buildings, there are more and more high-rise buildings. For example, developers now build a lot of loft buildings. In these high-rise buildings, residents are required to separate the high-rises by themselves to form a double-layer space. However, the storey heights of existing high-rise buildings are relatively low, generally less than 5 meters. Therefore, when separating the jump floors, the floor slabs separating the jump floors are required to be as thin as possible while meeting the strength requirements, so as to save space and increase the floor height. At the same time, since the current buildings are all high-rise buildings, once a fire occurs, the consequences will be disastrous. Therefo...

Problems solved by technology

However, the existing floor slabs are usually made by interspersing some steel bars in cement mortar, and the strength of this floor slab is relatively low.

Therefore, in order to increase the strength of the floor to meet the load-bearing requirements, the floor is made thicker, which can occupy a lot of space and reduce the height of the floor, which is difficult to meet the demand for the floor of the high-rise building.
