Damp-proof and anti-corrosion fabricated building steel structure

Abstract

The invention belongs to the technical field of building construction, and discloses a damp-proof and corrosion-resistant fabricated building steel structure which comprises a fixing plate, two first steel plates are movably mounted on the upper side and the lower side of the fixing plate correspondingly, and the two first steel plates are fixedly connected through a second steel plate. By arranging the vertical rods and the first springs, due to the elastic force recovery effect of the first springs, the vertical rods can drive the movable plates to move downwards, at the moment, the movable plates can drive the bottom blocks to enter the first steel plates to fix the first steel plates, the first steel plates and the second steel plates make close contact with the fixing plates, and separation is prevented; compared with a traditional device, the device has the advantages that excessive bolts can be prevented from being used, the possibility that the bolts slip is reduced, meanwhile, a good fixing effect can be achieved, and workers can conveniently and rapidly mount and dismount the device.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a moisture-proof and anti-corrosion type prefabricated building steel structure. Background technique [0002] The prefabricated building steel structure is the mainstream building construction method now. It has the following advantages: the steel structure is lightweight and high-strength, saves materials, saves energy, water and land during the construction process, the materials can be disassembled, recyclable, and the recovery rate reaches 70% A well-designed and excellent steel structure has a lower cost, and the exterior surface of the existing prefabricated building steel structure will be painted with a layer of waterproof paint, which can isolate the prefabricated building steel structure from the outside world and effectively prevent moisture and corrosion. [0003] At present, the prefabricated building steel structure is usually used in the construction...

AI Technical Summary

Problems solved by technology

[0003] At present, prefabricated building steel structures are usually used during construction work on construction sites. The prefabricated building steel structures in the prior art are usually fixed with a large number of bolts. Due to the large number of bolts, the prefabricated building The workload of installation and disassembly of building steel structures is greatly increased, and a large number of screw fixings are prone to partial slippage. At the same time, the bolts have weak anti-seismic function and are easily deformed, resulting in failure to use normally. Therefore, it needs to be improved. and optimization
