Embodiment Construction
[0034] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0035] Such as image 3 , a self-assembled self-supporting steel pipe scaffolding system, including a prefabricated assembly base unit 11 and a lattice column vertical pole unit. Such as Figure 6 and Figure 5 , the prefabricated assembly base unit 11 includes a prefabricated bottom plate 12-C, a prefabricated A plate 12-A, a prefabricated B plate 12-B, a prefabricated A plate 12-A and a prefabricated B plate 12-B each having two rows of multi-column through holes 13 The prefabricated floor 12-C is stacked alternately from bottom to top, and the adjacent surfaces between the prefabricated floor 12-C, prefabricated A-board 12-A, and prefabricated B-board 12-B...

The invention discloses a prefabricated self-supporting steel pipe scaffolding system. The lower end of the lattice column type vertical pole unit is fixed in the prefabricated assembly basic unit to increase the anti-overturning ability of the frame body, and a slanted frame is erected between the vertical poles. Steel pipes and horizontal steel pipes can prevent the vertical deformation of the vertical pole units. Multiple vertical pole units are connected into one body through horizontal horizontal rods, so that multiple vertical pole units can be used as columns of the traditional frame, and the Multiple columns are connected by shear braces to prevent deformation in the lateral direction of the frame, which improves the current situation that the traditional scaffold structure is geometrically deformable due to the large variation in the anti-rotational stiffness of the fasteners. At the same time, because the prefabricated and assembled basic unit has a detachable structure, it is beneficial to the disassembly and recycling of the self-supporting scaffold.
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 the reform, the aging problem of housing construction has become increasingly prominent. There are more and more retrofit projects for old buildings. Because old building renovation projects often involve overall structural demolition or large-scale demolition construction, some projects use external scaffolding to enclose and shield the renovated buildings during the entire construction period in order to meet the requirements of dust control and reduce social adverse effects. At the same time, due to the problem of no structural wall attached to the enclosure in the construction stage of the structural demolition in the reinforcement and reconstruction project, this type of enclosure needs to meet the requirements of the stability of the frame its...
