Description

Technical Field

[0002] At present, with the rapid construction of grain warehouses in large quantities, their structural form is generally a shallow silo structure. The top of the silo is a sloped cone shell plate with a slope of about 25°. There is often a trestle for belt conveyor above the cone shell plate structure of the silo. The trestle is generally a concrete structure, so the formwork support system will be set up on the sloped cone shell plate during construction. In the existing construction process, it is customary to directly set up the vertical pole on the slope surface, and then insert a wedge-shaped wooden block at the bottom of the vertical pole, that is, pre-embed the steel bar head on the cone shell plate surface or implant the steel bar head behind, put the vertical pole on the steel bar head, and then insert the wooden block around it. However, the actual effect is too poor. On the one hand, in the support frame system scheme, the design of the vertical pole foundation conditions is calculated based on a solid concrete horizontal plane, resulting in inaccurate calculations. On the other hand, the anti-slip ability of the wedge-shaped wooden block cannot be guaranteed and the angle is difficult to adjust. It is difficult to provide a horizontal plane to set up the template to support the vertical pole, and it is impossible to ensure a stable and horizontal vertical pole foundation plane. The entire support system is difficult to verify safety, resulting in the on-site construction safety cannot be guaranteed. Summary of the invention
