Mobile box column abutting-joint assembly connecting part with expansion locking liner

Abstract

A mobile box column abutting-joint assembly connecting part with an expansion locking liner comprises box columns, an inner casing, locking pins, a steel wire snap ring, cone linings and bolts. The mobile box column abutting-joint assembly connecting part is characterized in that the inner casing is a column-shaped tubular connecting part, wherein each end of the inner casing is in a step platform shape; the cross section of the inner casing is in a square shape which is matched with the cross section of the inner wall of each box column; the outer wall of the middle of the inner casing is provided with a circle of protruding ring; the pipe wall which is formed on each side of the protruding ring is provided with a pair of circular holes which are used for installing the corresponding locking pin; the diameter of each locking pin is matched with that of the corresponding circle holes; each locking pin is in a circular pipe shape; each end of each locking pin are cut into four pieces; the inner wall of the top of each end of each locking pin serves as a conical opening; every cone lining is arranged at the position of the corresponding conical opening; the two locking pins which are arranged at the two ends penetrate two circular holes which are formed in the upper box column and the lower box column respectively to be arranged in the corresponding circular holes of the inner casing; each bolt penetrates the corresponding locking pin to enable the corresponding box column and the inner casing to be fixedly locked. The mobile box column abutting-joint assembly connecting part with the expansion locking liner is simply structured, easy to detach and installation, requires low cost, and possesses high precision; construction manufacturing amount can be reduced; and structural assembling efficiency can be improved.

Description

technical field [0001] The invention relates to a mobile building component, in particular to a mobile box column butt joint assembly connector with an expansion locking lining. Background technique [0002] With the widespread use of prefabricated mobile buildings, steel structure mobile buildings are built on site according to needs, and many connections between box columns are required during site construction. At present, a large number of steel structure boxes are stacked and installed. The butt joint between the column and the lower column generally uses a structure in which the gusset plate and the gusset plate are fastened by several bolts, or is usually assembled on site and connected by electric welding. In the process of on-site construction, the assembly workload is large, the labor intensity is high, the workload is large, and disassembly and assembly are not easy. People pay more and more attention to reducing labor intensity and improving work efficiency. Peo...
