Description

Technical Field

[0001] The utility model relates to the technical field of steel support frames, in particular to a quick-disassembly steel support frame. Background Art

[0002] A scaffolding refers to various supports erected at a construction site for workers to operate and solve vertical and horizontal transportation problems. By stacking layers, the height of the scaffolding can meet the usage requirements of construction workers, facilitating construction workers to carry out construction operations at high altitudes. The steel support of the scaffolding is one of the main accessories of the scaffolding, mainly playing a role in supporting and maintaining the stability of the scaffolding. Publication number: CN218205560U, a scaffolding with stable support, includes a bottom plate, the bottom plates are symmetrically distributed left and right, a limiting rod is installed between one bottom plate and another bottom plate, symmetrically distributed vertical rods are installed at the upper end of the bottom plate, and a cross rod is installed between one vertical rod and another vertical rod. This scaffolding uses the bottom plate, limiting rod, vertical rod and cross rod to piece together the overall structure of the scaffolding, with uniform force, not easy to deform, strong bearing capacity, and firm connection of each part, facilitating installation and disassembly, and convenient transportation. Through the auxiliary support component, the support piece can be replaced according to the construction road surface conditions, so as to firmly fix the scaffolding on the ground and prevent the scaffolding from sliding. At the same time, the height of each support piece can also be adjusted according to the uneven ground conditions. However, when using the above technology, since the auxiliary support component is fixed on the scaffolding, the position of the auxiliary support component cannot be adjusted according to the usage position of the scaffolding, and it is also inconvenient for personnel to disassemble, assemble and maintain the auxiliary support component. Therefore, improvements are needed. Summary of the Utility Model
