Prefabricated assembly type self-supporting steel pipe scaffold system

Abstract

The invention discloses a prefabricated assembly type self-supporting steel pipe scaffold system. The lower end of each lattice column type vertical upright rod unit is fixed to a prefabricated assembly base unit, the anti-overturning capacity of a frame body is increased, oblique sew steel pipes and transverse sew steel pipes are erected between vertical upright rods, then each vertical upright rod unit can be prevented from height-direction deformation, the vertical upright rod units are connected into a whole through transverse horizontal rods, the plurality of vertical upright rod units serve as columns of a traditional frame body, the plurality of columns are connected through shear supporting, the transverse direction of the frame body is prevented from being deformed, and the situations that the traditional scaffold is relatively large in resistance to rotation rigidity of the fasteners and the whole frame body structure belongs to the geometric variable body are improved. Meanwhile, due to the fact that the prefabricated assembling base unit is provided with the detachable structure, the disassembling and the cyclic turnover utilization of the self-supporting scaffold are facilitated.

Description

technical field [0001] The invention relates to the technical field of old building scaffolding, in particular to a prefabricated self-supporting steel pipe scaffolding system. Background technique [0002] With the deepening of reform, the aging problem of housing construction has become increasingly prominent. There are more and more projects for the reinforcement and renovation of old buildings. Because the renovation projects of old buildings often involve the overall demolition of the structure or the construction of large-scale demolition, in order to meet the requirements of dust control and reduce the impact of adverse social effects, some projects use external scaffolding to enclose and shield the reconstructed buildings during the whole construction period. At the same time, due to the problem of no structural wall attached to the enclosure body during the structural demolition construction stage of the reinforcement and reconstruction project, this type of enclos...

Problems solved by technology

[0003] The invention aims to solve the problems of insufficient self-supporting height and easy deformation and instability of traditional scaffolding, and provides a lattice column scaffold structure, and configures an easily disassembled assembly base unit for the lattice column scaffold unit to obtain a prefabricated assembly Self-supporting steel pipe scaffolding system, it is easy to disassemble, the overall structure can be recycled and reused, and at the same time solve the problem that the free height of the double-row scaffold is too low when there is no structure attached to the wall
