[0149] Step 4: Put the hollow steel pipe skeleton obtained in Step 3 into the reinforced grid frame 5 obtained in Step 1;

[0150] Step 5: Install baffles around the outer sides of the reinforced grid frame 5 with hollow steel pipe skeletons inside the obtained step 4, and pre-embed corrugated pipes at the...

Embodiment 3

[0154] Embodiment 3: The use of the prefabricated light-weight floor slab of the present invention

[0155] Such as Figure 4-5 , this embodiment 3 provides an assembly method of a prefabricated lightweight floor slab in embodiment 1. A stud is welded on both wings of the steel beam, and then the stud is respectively inserted into two adjacent lightweight floor slabs 1 In the center of the stud hole 8, the extra longitudinal reinforcement 9 is bound, the extra space inside the stud hole 8 is poured with ordinary concrete, and finally the gap between the steel beam and the two lightweight floor slabs 1 is filled with high-performance Concrete 11 pouring.

[0156] Preferably, the peg is a steel nail with a cap diameter of 50mm and a nail body diameter of 20mm.

Abstract

The invention discloses a prefabricated assembly type lightweight floor and a manufacturing method thereof, and belongs to the technical field of building materials. The invention provides the prefabricated assembly type lightweight floor composed of a concrete matrix, a hollow steel tube, a batten plate, a reinforcing mesh frame, a hollow steel tube hole, a lightweight filling material and a toggle pin hole and the manufacturing method thereof, not only is the problem of large self-weight of a traditional cast-in-place floor solved, but also the problem of the lower intensity of lightweight concrete is solved, and the practical significance and engineering application value are significant.

Description

technical field [0001] The invention relates to a prefabricated assembled lightweight floor slab and a manufacturing method thereof, belonging to the technical field of building materials. Background technique [0002] The prefabricated structural system refers to the building produced by making housing units or components according to uniform and standard building part specifications, and then transporting them to the construction site for assembly in place. It is characterized by light building weight, energy saving and environmental protection, fast construction speed, and high degree of industrialization. It can solve many problems such as low level of construction industrialization, low labor productivity in house construction, and low quality of traditional house products, and adapts to the development of the construction industry. [0003] At present, the prefabricated floor slabs mainly used mainly include cast-in-place floor slabs and laminated floor slabs. The cas...
