Method for connecting external scaffold with wall for large-span and ultra-story-height structures

Abstract

The invention discloses a method for connecting an external scaffold with a wall for large-span and ultra-story-height structures. Connecting pieces (2) are embedded on the edge beam column of large-space concrete main body structures (1) and are used as wall connecting points (3); when an ultra-story-height structure is met, vertical inclined pulling steel pipes (5) are adopted to be connected with the external scaffold (4); included angles among the vertical inclined pulling steel pipes (5) and the main body structures (1) are 45-60 degrees; when a large-span structure is met, the external scaffold (4) is reliably connected with the main body structures (1) by adopting transverse inclined pulling steel pipes (7); and the included angle among the protections of the transverse inclined pulling steel pipes (7) on a horizontal plane and the external scaffold (4) is 45-60 degrees. The method solves the setting problem of the wall connecting piece of the external scaffold of the large-span and ultra-story-height structures, is applicable to public constructional engineering with difficult fixation of the wall connecting pieces of the large-span and ultra-story-height structures, can effectively guarantee construction safety, meets construction requirements, effectively utilizes resources, lowers engineering investment, and has wide market application prospect.

Description

technical field [0001] The invention relates to the technical field of E04G scaffolding, formwork; formwork construction tools or other construction auxiliary devices [0002] The field involves scaffold erection construction technology, embedded parts installation and construction technology, steel bar and concrete construction technology, especially the method of connecting external scaffolding to walls of large-span and super-high structures. Background technique [0003] In the field of construction, scaffolding is an important construction equipment, and fastener-type steel pipe scaffolding has the advantages of large bearing capacity, convenient assembly and disassembly, flexible erection, and economical applicability. Its double-row scaffolding system has been widely used in construction projects. In the construction process of general buildings, it is easier to connect the external scaffolding wall parts to the main structure, but in large-span, super-high structures...

AI Technical Summary

Problems solved by technology

For cantilever scaffolds with a large frame height, even if the height-to-width ratio is reasonable, under the action of wind load, when the foundation bearing capacity is insufficient, it will still have an adverse effect on the overall stability of the frame.

Under the above three working conditions, if a dense mesh safety net is hung in a large area, it will be extremely unfavorable to the stability of the scaffold.
