Description

Technical Field

[0001] The utility model belongs to the field of steel structure workshops, and particularly relates to an assembled oblique span connection steel structure workshop frame. Background Art

[0002] The angle of the roof of a steel structure factory building cannot be adjusted. After the factory building is assembled in the later stage, the drainage will be limited, especially in rainy or snowy areas. The fixed roof angle may not be able to effectively drain rainwater or snow, thereby increasing the risk of water accumulation on the roof. Long-term water accumulation will not only corrode the roof material, but may also cause roof leakage, thereby affecting the environment inside the factory building. Therefore, a factory frame is needed to cooperate with the roof angle adjustment after the later assembly is completed.

[0003] After searching, it is found in the prior art that there is a steel structure factory building with an adjustable top inclination and the publication number is CN113684978A. The device adopts an angle adjustment mechanism to adjust the roof inclination, and the angle of the inclined beam is adjusted by driving the steel cable through motor I, and the movable block and the fixed block are slidably connected; the inclination of the inclined beam is controlled by controlling motor I to clear snow and other debris on the roof, and the movable block and the fixed block on the inclined beam are used to fix the purlins installed on the roof; the device drives the steel cable by controlling motor I, and pulls the steel cable by gravity through the roof and the inclined beam, but affected by the environment (such as strong wind), the roof will shake uncontrollably, and the shaking will cause the roof to drive the inclined beam to hit the connection of the factory building, resulting in poor stability of the factory building.

[0004] After searching, it is found that in the prior art, there is an adjustable support frame of a steel structure factory building with a publication number of CN215519489U. When the operator adjusts the inclination angle of the steel frame beam, the inclination angle of the steel frame beam can also be adjusted by sliding the support member. It should be understood that the length of the support member is fixed. When the operator holds the support member and slides it toward the side close to the ridge, the angle between the steel frame beam and the support column will decrease accordingly. On the contrary, when the operator holds the support member and slides it toward the side away from the ridge, the angle between the steel frame beam and the support column will increase accordingly. When the device adjusts the angle of the steel frame beam, it is necessary to control the angle of the steel frame beam by sliding the support member and the U-shaped slider on the crossbeam. However, when adjusting the angle of the steel frame beam in the later stage, the fixing member between the U-shaped slider and the crossbeam needs to be disassembled each time to adjust the steel frame beam. At the same time, external equipment is also needed to limit the steel frame beam to prevent the weight of the steel frame beam from being too heavy, which makes it impossible for the staff to adjust the angle of the steel frame beam through the support member. Summary of the invention
