Technical field

The invention relates to the technical field of building construction, and in particular to a steel truss floor deck opening sealing mold and a method of use.

Background technique

Steel truss refers to a truss made of steel bars as upper chords, lower chords and web members, connected by resistance spot welding. Reinforced truss floor bearing plate refers to a composite load-bearing plate that connects the steel truss and the bottom plate (profiled steel plate) through resistance spot welding. It can withstand the dead weight of wet concrete and construction load during the construction stage. It can significantly reduce the amount of on-site steel tying work. , the advantages of easy disassembly and assembly of prefabricated formwork and connectors and improving the progress of on-site construction; during the construction process, two adjacent steel truss floor decks are connected through Yin and Yang buckle ties, so that multiple steel truss floor decks can The plates form a whole.

During the use of the steel truss floor deck, it is necessary to reserve opening positions; at the same time, in order to ensure the overall structural strength and bearing capacity of the steel truss, as well as the quality of the concrete after construction, it is necessary to wait until the concrete of the floor deck reaches 75% of the design strength. Only then can the steel bars and steel plates of the steel truss floor deck be cut. Therefore, in the prior art, openings are reserved in the steel truss floor decking by means of formwork, and after the concrete layer reaches strength, the formwork is removed and the steel truss floor decking is cut off to form the opening.

As one of the existing construction methods, wooden formwork is used to set up the formwork to form an opening. Steel nails are used to fasten the wooden formwork. A jagged gap is preset on the wooden formwork for the steel truss to pass through. At the gap, Concrete is intercepted by tying steel bars or steel wires; in this method, the wooden formwork is removed after the concrete slab is formed, but the formwork usually suffers from high losses. As the second existing construction method, when concrete columns and beams are poured in stages, steel wire mesh is placed around the opening to intercept the concrete, that is, the steel wire mesh is tied to the steel truss and the hole is formed in a circle; however, this method For steel truss floor decking, the concrete pouring height is higher than the truss steel bars. The steel wire mesh tied to the steel truss cannot form the same effective interception effect on the concrete layer higher than the truss as the lower layer.
