Description

Technical Field

[0001] The utility model relates to the field of steel structures, in particular to a detachable assembled building steel structure. Background Art

[0002] At present, a Chinese utility model with the announcement number CN212478094U discloses a detachable assembled building steel structure, including a base, the four corners of the inner bottom wall of the base are fixedly connected with a fixing seat, the tops of the four fixing seats are all penetrated and extended to the top of the base, the insides of the four fixing seats are plugged with square steel columns, a main beam is arranged between two adjacent square steel columns, the two inner sides of the four square steel columns are provided with fixing openings, the two ends of the four main beams are respectively plugged with the adjacent fixing openings, the two sides of the bottom of the four main beams are fixedly connected with a connecting plate, the side of the connecting plate away from the main beam is fixedly connected to the square steel column, the inner sides of the four fixing seats are provided with through openings, and the inner sides of the four square steel columns are provided with sockets. This utility model solves the problem that the assembly by welding is not easy to disassemble in temporary construction projects, which is not conducive to the recycling of steel structure components.

[0003] Although the existing building steel structure can fix the beams on the beams and columns by bolts to achieve prefabricated installation, there are still other problems during use. For example, it does not have a height difference adjustment function. The beam will be in a fixed position after installation. If there is a difference between the other end of the beam and the other beam and column and they cannot correspond, the bottom can only be paved by removing the beam and column. Not only is the operation cumbersome, it also has a certain impact on the construction progress, and the stability of the beam is poor. The beam and the beam are fixed by only two bolts. The bottom of the beam is in a suspended state and there is no reinforcement component on the top, which can easily cause deformation at the connection position and weaken the bearing capacity. In order to solve the above problems, we propose a detachable prefabricated building steel structure. Utility Model Content

[0017] The utility model is further configured that surfaces of the beams, adjustment piles, installation piles, cross beams and top plates are all coated with anti-corrosion paint.

[0018] By adopting the above technical solution and setting the anti-corrosion coating, the anti-corrosion effect of the surface of beams, columns, adjustment piles, installation piles and beams can be improved, thereby extending their service life.
