Floor bearing plate construction details which to have

Composite floor plate for the heavy machine production of the steel building bearing plate shape concise, wave degree, high strength, installation laying welding mesh reinforcement and concrete after a watering combination, adhesive, on a high building can save steel template, but also can reduce the floor load, at the same carrying capacity next, make engineering steel amount is reduced, thereby saving investment. Floor bearing plate with a special clamping jaw occlusal pressure hole plug connection; special galvanized plug plate and the bearing plate and steel spot welding.

When the floor structure layer elevation change is inconsistent, adopts welded steel measures the level of structure, a step transition, when the lower elevation when the beam web and welding angle; when the lifting elevation beam with welded steel. When the floor is reserved holes size is generally greater than 500mm× 500mm by first opening measures, namely in steel beam with welded steel joists spaced, increase the stiffness, mesh reinforced at the entrance of the cave is disconnected, and the steel welding; the hole size is less than 500mm× 500mm taken after opening measures, i.e. the building bearing plate is added on the plug mesh partition plate, reinforced through, concrete pouring molding after shear reinforcement.

Design of composite slabs with standard reference:

1 composite slab bearing capacity shall be based on actual use of the supporting state ( single, double cross, three cross ) and material thickness, according to the national standard GB/T 50010-2002 and GB/T 50018-2002 design.

The 2 floor bearing plate except in construction as a template and can be used in stage floor required all or a portion of the lower tensile reinforcement.

3 combined floor plates can be designed as simple span or continuous span continuous composite slab, cross, bearing the negative reinforcement should be in accordance with the relevant design codes.

4 Design Engineer on temperature reinforcement should be based on the design specifications.

5 concrete height shall be not less than the floor bearing plate wave 50mm.

6 combined floor plates in the construction stage around the limit below L/180 ( L is the span of slab ), later allowed slab under uniform load, the deflection limit is less than L/360.

The 7 floor bearing plate minimum moment of inertia and the minimum cross section coefficient should meet the engineering design specification, shall comply with the pressure plate design design and construction specification.
