Introduction to the advantages and precautions of floor deck trusses

The floor deck truss, also known as the steel bar truss formwork, is a combined 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 the steel bar truss and galvanized steel plate into a whole. In the construction stage of the structural floor slab, the system replaces the construction template with galvanized steel plate, and the truss structure constructed by steel bar welding in the structure jointly bears the concrete weight and construction load of the floor slab, and after pouring concrete, it forms a reinforced truss concrete floor slab, accepts the application load in the application stage, 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 advantages of floor deck trusses? Here's an introduction.

1. It has a very good grip with the concrete to prevent it from slipping off from the concrete;

2. The centroid of the composite floor section is very close to the bottom of the slab, which has a stronger resistance to the positive bending moment;

3. The special design of the closed rib has fire resistance;

4. The superior suspension system can be moved, removed, or re-installed;

5. The construction is simple and fast, and there is no need for any plug and there will be no leakage, shortening the construction period;

6. The appearance of the bottom of the plate is smooth, and it can be beautiful and generous without the need to be in the ceiling at the bottom of the plate.

What aspects need to be paid attention to in the construction of floor deck trusses? Let's take a look at what follows.

1. When installing the floor deck truss, the ordinary demand is based on the second floor from bottom to top to stop the device, when the floor deck of each floor is transported in place by the crane, the floor deck of the top floor should be installed first, so that the safety of the device and the operation in rainy days will be more convenient.

2. In the construction process, the mother buckle of the floor bearing plate should be used as the starting edge of the datum, and then the beginning of the laying should be stopped in turn, in the laying process, the bearing plate of each floor should be stopped and positioned according to its effective width, and the block should be used as a unit, while laying while positioning, the beam surface should be welded with the stud, and the center of the bottom plate groove should coincide with the center of the flange.

3. If the floor slab connecting the column or beam and the column is to be cut or opened, it is necessary to use a plasma cutting machine to stop cutting, or you can choose to use other cutting methods agreed by the owner or the supervisor to stop cutting.

4. When the floor deck truss stops closing the edge, or the baffle is set up, or the baffle stops reinforcing it, the concrete should be poured according to the progress request, and the demand is completed on time, in order to ensure the construction quality of the floor deck and prevent the safety and stability of the building from being affected, it is recommended that we must ask a professional and experienced construction team to help stop the construction, so that it is not easy to present problems.
