Welding method for steel structure truss

The steel structure truss floor support plate needs to be welded with steel bars in the processing plant to make a steel bar truss. In addition, it is welded together with the plate to form a complete steel bar truss floor support plate, which can bear very heavy concrete and construction machinery

The concrete floor slab using steel structure truss floor support plate combines the advantages of traditional cast-in-place concrete floor slab with good overall integrity, high stiffness, and good performance, as well as the advantages of no formwork and fast construction of profiled steel plate composite floor slab. The stress mode of the steel structure truss floor support plate truss is reasonable, and the truss height and steel bar diameter can be adjusted to achieve a large span

The steel-concrete composite floor using steel truss floor support plates can reduce secondary beams, have appropriate shear bolt welding speed, and stable construction quality. As a mature technology, steel truss buildings have been widely used in construction projects in many regions and have broad application prospects in multi story and high-rise buildings

The steel bar truss floor support plate combines the steel bars in the concrete floor slab with the construction formwork, so it is a load-bearing component that can withstand the self weight of wet concrete and construction loads during the construction phase. Moreover, this component can be used as lateral support for steel beams during the construction phase. During the usage phase, the steel truss and concrete work together to withstand the usage load

Unlike traditional construction methods, in the construction site, the steel truss floor support plate can be directly laid on the beam, and then simple steel reinforcement engineering can be carried out to pour concrete. The construction of the floor support plate does not require the installation of wooden templates and scaffolding, and the bottom galvanized steel plate is only used as a template and does not replace the load-bearing steel bars. Therefore, there is no need to consider spraying and maintenance issues, and very thin steel plates can be used

Moreover, the main load-bearing steel bars of the floor slab are positioned and welded into shape on the automatic control production line. The steel bars are evenly arranged, accurately positioned, and the construction speed is suitable, which can reduce the on-site steel bar binding workload by about 70%, greatly shorten the construction period, and save costs. The spacing between the upper and lower layers of steel bars and the thickness of the concrete protective layer can be fully protected, creating favorable conditions for improving the quality of floor construction. The steel truss floor support plate welds the steel reinforcement bones into a whole, with high overall stiffness. When pouring concrete on the floor slab, the deformation is small, and temporary support is generally not required. It can also withstand large construction stage loads
