Description

Supporting device for floor support plate Technical Field The utility model relates to the technical field of civil engineering construction, in particular to a supporting device of a floor supporting plate. Background At present, the supporting device of the floor support plate is used as a key temporary support system in cast-in-place concrete construction, and is particularly widely applied to steel structure building engineering. This type of structure is generally used for supporting profiled steel sheets arranged on steel beams and completing the casting work of concrete floors thereon. The traditional support system is mainly composed of a steel pipe column, a disc buckle frame or a sleeve type steel support member, and is built through screw threads, bolts and the like. These constructions have certain advantages in terms of versatility and bearing capacity, but in practical steel construction scenarios, there are still significant drawbacks in terms of operational convenience, adjustment accuracy and connection stability. However, the supporting device of the existing floor support plate, such as the full-hall support of the disc-buckle type scaffold, still has a plurality of problems in practical application. On one hand, the node connection is usually in a rigid connection mode such as bolts, pin shafts or bolts, and the structural stability is greatly dependent on the assembly precision and locking quality of manual operation. Under construction disturbance, long-term load or frequent disassembly and assembly conditions, the connection part is easy to loose or deviate, and the stability of the whole support system is reduced. On the other hand, the current bearing structure generally adopts coarse pitch lead screw or sleeve adjusting device, and the regulation precision is lower, is difficult to realize millimeter level fine adjustment. In steel construction floor construction, building carrier plate braced system if can not provide reliable node location and high accuracy's altitude control, will be difficult to guarantee concrete floor's elevation uniformity and closely laminate with the girder steel, easily lead to quality problems such as floor thickness inequality, fire prevention protective layer thickness error, and then influence floor structure's overall security, construction quality and durability. Based on the state of the art, the utility model provides an improved supporting device for a floor support plate, so that the problems that an existing structure depends on manual operation, is easy to loosen and has insufficient height adjustment precision in a connecting mode are solved, and further quality hidden troubles such as uneven floor thickness, unsmooth bonding with a steel beam, deviation of a fireproof layer and the like caused by unstable support or elevation error are avoided, and the construction precision, safety and usability of the structure are ensured.
