Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a temporary support assembly for a steel truss floor deck. Background Art

[0002] In the field of modern construction, especially for high-rise or large-span buildings, steel structures are widely used due to their high strength, light weight and good earthquake resistance. Floor deck is a prefabricated component used to form the floor of a building, which combines the advantages of two materials: steel truss and concrete. The stress-bearing process of the floor deck is divided into the construction stage and the use stage. The construction stage is the process from the beginning of the assembly of the floor deck to the concrete strength reaching the design requirements. In this process, the self-weight of the floor deck, the weight of the wet concrete and the construction live load are all borne by the steel truss, which is usually welded by steel bars; when the concrete strength reaches the design requirements, the floor deck enters the use stage. In this stage, the upper and lower chord steel bars of the steel frame work together with the concrete, and its stress performance and bearing capacity are the same as those of ordinary cast-in-place concrete floor slabs. In actual applications, the floor deck is usually installed on a pre-constructed steel beam. The steel beam is the basic structure for bearing the floor deck, and the steel beam is usually made of H-shaped steel.

[0003] When the floor decking is laid or the temporary load of pouring concrete is too high, it is inevitable that there will be a large deflection or even collapse in the mid-span of the floor decking. In order to ensure construction safety and the overall strength, rigidity and stability of the floor decking, it is sometimes necessary to set up temporary supports under the floor decking after the floor decking is installed and before the concrete is poured. The temporary supports and the floor decking as a whole bear the deadweight of the components and the construction load. Traditional temporary supports are mostly in the form of steel pipe supports, and the cost of using full-floor scaffolding is relatively high. In addition, this method must be carried out after the lower layer of concrete has been poured and cured to reach a certain strength before it can be supported on it. The entire construction process can only be carried out from bottom to top, which seriously reduces construction efficiency and has an adverse impact on the construction period. It is difficult to meet the requirements of rapid construction of super-high-rise buildings, so it needs to be improved. Summary of the invention

One end of the fixing block 32 extends out of the fixing groove 31 and is provided with a mounting groove 321 for the lower flange of the steel beam to be inserted into. A mounting spring 33 for pressing against the fixing block 32 is fixedly connected between the fixing block 32 and the bottom wall of the mounting groove 321, and the mounting spring 33 always presses against the fixing block 32. A limiting rod 322 is fixedly connected to the outer wall of each fixing block 32, and a first sliding hole 37 is provided on the inner wall of the fixing groove 31 for the limiting rod 322 to pass through and slide. When installing the temporary support assembly, first press the fixing blocks 32 on the two fixing rods 3 into the fixing grooves 31 through the limiting rods 322, then lift the fixing rods 3 to the lower flange of the steel beam, loosen the fixing blocks 32, and the lower flange of the steel beam is inserted into the installation grooves 321 on the fixing blocks 32, so that the connecting rod 1 is installed between adjacent steel beams, and the supporting part 2 on the connecting rod 1 can support the floor decking.

The staff lifts the fixing rod 3 through the first extension rod 5 and the second extension rod 6. At this time, the fixing rod 3 and the lower flange of the steel beam are not in a vertical state. The lower flange of the steel beam is aligned with the installation groove 321 on the fixing block 32, and then the two fixing rods 3 are rotated in the horizontal direction so that the fixing rod 3 and the steel beam are in a vertical state. The lower flange of the steel beam is stuck in the installation groove 321 on the fixing block 32, so that the temporary support assembly is fixed between the two steel beams.
