Abstract

The invention discloses a positioning construction method for butt joint bolts of a multilayered steel column and solves the technical problem that section columns connected in an existing steel framesystem are complex in construction step, inaccurate to position, great in perpendicularity deviation and hard to correct. The construction method comprises the following steps: enabling an upper positioning part and a lower positioning part to correspond to each other and match with each other, and meanwhile, inserting a liner plate between an upper section column and a lower section column, wherein bolts can be positioned accurately and are high in perpendicular precision; after butt joint positioning, matching a groove opened outward in a connecting port with the inner linear plate to reserve a weld joint, and welding the upper section column and the lower section column through the full penetrating groove weld joint opened outward; and after the upper section column and the lower section column are mounted in a butt joint manner, screwing out high-strength bolts from a connecting plate, wherein the upper and lower positioning parts can be taken down for repeated use, and a condition that the inhered performance of a section column structure by forming bolt holes in the section columns is avoided.

Description

technical field [0001] The invention relates to the technical field of steel structure buildings, in particular to a positioning construction method for butt joint bolts of multi-layer steel columns. Background technique [0002] Steel structure buildings have the advantages of low energy consumption, less construction waste, and short construction periods, and are green buildings that meet sustainable development. At present, domestic steel structure building systems are mostly steel frame systems, steel frame-concrete core tube systems, steel frame-shear wall systems, and steel frame support systems. The column structures in the above systems mostly adopt cross-shaped columns, box-shaped columns, etc. When the cross-shaped columns are connected to the cross-shaped columns, and when the box-shaped columns are connected to the box-shaped columns, ear plates, connecting splints and high-strength bolts are usually used. However, this traditional construction procedure is very...
