Description

Technical Field

[0001] The utility model relates to the technical field of a lattice column, and more specifically, to a standard section of a plane frame and a loose-parts assembled lattice column. Background Art

[0002] Lattice columns are a kind of temporary support system widely used in the installation process of steel structures. They are mainly used in the following two applications: 1) as temporary support for the structure when the steel structure is hoisted in sections; 2) as support for floor reinforcement when the lifting equipment is walking on the floor or there is a large concentrated load on the floor. The following solutions are mainly used to select lattice columns: 1) Lease scaffolding poles to set up load-bearing brackets. This is an earlier solution. Scaffolding poles are small in cross-section and easy to bend, so the single-pole bearing capacity is low. When used for load-bearing brackets, many poles are needed to meet the use requirements. The technical, practical, economic, and safety aspects are not good, and it is rarely used now. 2) Temporary purchase of steel sections to make load-bearing brackets; This solution does not make long-term systematic considerations on technology, practicality, economy, and safety. This solution can solve the immediate problem, but its practicality and economy are not good. 3) Renting tower crane sections as load-bearing brackets; Because the tower crane section is part of the equipment, it was not originally designed to be used as a load-bearing bracket. It is a waste of material, and its practicality and economy are not good. Utility Model Content
