A large inventory of the characteristics of floor deck trusses

The floor deck truss, also known as the steel bar truss template, is a composite structural system that processes the main stressed steel bars in the floor slab into a steel bar truss with special equipment in the factory, and then welds it into a whole with galvanized steel plate. In the construction process of the structural floor slab, the system is replaced by galvanized steel plate, and the truss structure constructed by steel bar welding in the structure jointly bears the self-weight and load of the floor concrete, and after pouring concrete, it constitutes its floor slab, and accepts the operating load in the application process, and is currently widely used in multi-storey workshops, multi-storey, high-rise, high-rise steel structure buildings, various irregular floors, various prefabricated slabs, high-speed railways and other structural and architectural categories.

Floor deck trusses

What are the characteristics of floor deck trusses? Here's an introduction.

1. It has the advantages of good integrity, high stiffness, good fire performance, no module, fast construction speed of profiled steel plate composite plate, etc., and its bearing plate stress form is reasonable, and the truss height and steel plate diameter can be adjusted to complete a large span.

2. Floor deck truss floor deck steel-concrete composite floor can reduce secondary beams, fast welding speed, stable construction quality, as a mature new technology, it has been widely used in construction projects at home and abroad, and has a broad application prospect in multi-storey buildings.

3. It separates the steel plate from the formwork, and can accept the load-bearing member of the wet concrete self-weight and load in the construction stage, and can be used as the lateral support of the steel beam during the implementation process, and it and the concrete accept the load together during this period.

4. Different from the traditional construction method, on the site, it can be laid directly on the beam, and then simply reinforce the steel engineering and concrete, the wooden floor bearing plate does not need to set up the construction template and scaffolding, and the bottom of the galvanized steel plate only uses the module, does not replace the stress of the steel bar, does not need to think about fireproof coating and anti-corrosion maintenance, and can use thin steel plate.

5. In addition, the main reinforcement of the floor is positioned and welded on the automatic control production line, the steel bar is evenly arranged, the position is accurate, the construction speed is fast, the on-site steel binding work can be reduced by about 70%, the construction period is greatly shortened, the cost is saved, the upper and lower steel bar spacing and the thickness of the concrete maintenance layer are guaranteed, and favorable conditions are invented to improve the construction quality of the floor bearing plate, it welds the steel bar into a whole, the overall stiffness is large, the deformation of the floor bearing plate is small when pouring concrete, and the temporary support is generally not required, and the construction stage can accept a larger load.

The floor deck truss has strong corrosion resistance, can adapt to the complex building shape, and can make boards on site, so the length of the plate is not limited by the transportation request, and the length of the board is longer, so as to ensure that a roof panel can exceed the entire roof, reduce lap joints, and also reduce the possibility of water leakage.
