Cement floor support plate and manufacturing method thereof

Abstract

The invention provides a cement floor support plate and a manufacturing method thereof. The cement floor support plate comprises a bottom template with an embedded steel plate. Each steel bar truss comprises a group of upper chord steel bars and two groups of lower chord steel bars. The upper chord reinforcing steel bars and the lower chord reinforcing steel bars are welded into a whole through the wave-shaped web member reinforcing steel bars to form a three-dimensional structure truss with triangular end faces. The steel bar truss is welded with the steel bar mesh. The steel bar truss and the steel bar mesh as a whole are welded with the pre-embedded steel plate. A welding connection process is adopted, the bottom formwork body is provided with the embedded steel plate, production is more convenient, a bolt or screw connection mode is not needed, a punching production process is omitted, production efficiency is high, and performance is reliable. By adopting the reinforcing mesh, the defect of difficulty in on-site reinforcement penetrating can be overcome, manual transverse reinforcement penetrating is not needed, the problem of difficulty in on-site equipment pipeline construction is also solved, the labor intensity is reduced, and the construction cost is reduced.

Description

Technical field [0001] The present invention belongs to the technical field of cement building, and more particularly to a cement building board and a method of making it. Background technique [0002] In the construction field, the cement floor is more widely used, and the cement floor disclosed in the prior art also has the following problems: 1. Cement floor combination connection only bolts or screw connection methods; 2 The bolt or screw connection is used to high production accuracy, resulting in high cost of production equipment, low efficiency; 3. The number of steel truss is more and the bolt or screw is fixed, which requires a plurality of mounting holes to open by bolts. Or the screw is connected, the time is laborious, the production efficiency is low, the production capacity is not going; 4. Using bolts or screws, metal parts leakage rust problem is generally influencing engineering quality and residential comfort; 5. The number of steel bars is much larger, the dens...

AI Technical Summary

Problems solved by technology

[0002] In the construction field, the cement floor deck structure is more and more widely used, and the cement floor deck disclosed in the prior art still has the following problems in the use process: 1. The combined connection of the cement floor deck only has bolts or screw connections; 2. .The use of bolt or screw connection requires high production precision, resulting in high cost and low efficiency of production equipment; 3. The number of steel trusses is large and fixed with bolts or screws, which requires multiple installation holes on the bottom plate and then through the bolts or screws to connect, time-consuming and laborious, low production efficiency, and production capacity cannot be increased; 4. Using bolts or screws, the leakage and corrosion of metal parts are common, which affects the quality of the project and the comfort of living; 5. The number of steel trusses is large, the density is high, The amount of steel used is large, and a large number of steel bars are required to be constructed on site. Compared with mechanically produced steel mesh, the error is large and the quality is poor. It also makes the construction of on-site equipment and pipelines difficult, increases labor costs, and prolongs the construction period; 6. Floor deck steel truss Participating in the stress, the truss models have many types and are troublesome to produce. Due to the large design restrictions, it is difficult to achieve marked mass production; 7. At present, most cement floor decks use plastic connectors, which have poor fire resistance. The stripping of the main body is a great safety hazard; 8. The production process of the bottom formwork on the upper truss steel bars must be used in the production of bolt or screw connection, and the components need to be turned over in the later stage. This process equipment is bulky and expensive, and the production High cost and low production efficiency
