Processing technology of vacuum extrusion molding fiber cement composite floor slab

Abstract

The invention discloses a processing technology of a vacuum extrusion molding fiber cement composite floor slab. The processing technology comprises the following steps: preparing an ECP plate; preparing a steel bar truss (2); and the ECP plates (1) and the steel bar trusses (2) are assembled and fixed. The ECP plate and the steel bar truss which are high in strength are combined to serve as the laminated plate, the overall strength can be improved on the premise that the weight is reduced, and the ECP plate contains a large number of fibers. The multiple prefabricated holes formed in the ECP plate can serve as wiring holes and offline holes of water and electricity lines when the water and electricity lines are arranged, the complexity of follow-up construction is reduced, the clamping grooves are formed in the outer end face of the ECP plate, the lower chord steel bars of the steel bar truss are inserted into the clamping grooves from the side edges in a penetrating mode, and after installation is qualified, the lower chord steel bars of the steel bar truss can be inserted into the clamping grooves. The gap between the lower chord steel bar and the clamping groove is filled with the structural adhesive, so that the lower chord steel bar and the clamping groove are firmly fixed, steel bar trusses of different models can be clamped with the ECP plate only by changing the position of the clamped clamping groove, the process is simple, and the application range is wider.

Description

technical field [0001] The invention belongs to the technical field of laminated floor slabs, and in particular relates to a processing technology for a vacuum extrusion forming fiber cement laminated floor slab. Background technique [0002] The existing laminated board products in the industry are widely used in buildings such as floor structures, large-span structures, descending slab structures, sloped roofs, and residential structures. , The concrete prefabricated layer is used, and the bottom reinforcement is prefabricated in the prefabricated layer, and then cast in place. The thickness of the prefabricated layer and the cast-in-place layer is thicker, which increases the structural load more, and the finished product is not versatile. SUMMARY OF THE INVENTION [0003] In view of the deficiencies described in the above-mentioned prior art, the present invention provides a process for processing a fiber cement laminated floor slab by vacuum extrusion. [0004] The t...

Problems solved by technology

[0002] The existing laminated slab series products in the industry are widely used in buildings such as floor structures, long-span structures, descending slab structures, slope roofs, and residential structures. The main structural forms are reinforced truss laminated slabs, but the existing reinforced truss , the concrete prefabricated layer is used, and the bottom steel bar is prefabricated in the prefabricated layer, and then cast-in-place. The prefabricated layer and the cast-in-place layer are thicker, which increases the structural load more, and the finished product is not universal
