Example Embodiment

[0014] The present invention will be further explained below in conjunction with specific embodiments.

[0015] The large-space concrete main structure 1 is embedded in the connecting piece 2 on the edge beam and column, as the connecting wall point 3, when the super-high structure is encountered (attached figure 1 ), when the connecting piece 2 of the outer scaffold 4 and the main structure 1 cannot meet the requirements of two steps and three spans, the connecting piece 2 is embedded in the main structure 1, and the vertical inclined steel pipe 5 is used to connect with the outer scaffold 4. The angle between the steel pipe 5 and the main structure 1 is 45-60°, and the projection of the vertically inclined steel pipe 5 on the floor is perpendicular to the scaffolding plane; when it comes to a large-span structure (attached) figure 2 ), the horizontally inclined steel pipe 7 is used to form a reliable connection between the outer scaffold 4 and the main structure 1, and the proje...

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...
