Description

Technical Field

[0001] The utility model belongs to the technical field of industrial and civil construction, and particularly relates to a detachable external frame tie-joining assembly device. Background Art

[0002] In the field of industrial and civil construction technology, the traditional external scaffolding wall connection point is to embed vertical steel pipes in the frame beam. The embedded vertical steel pipes are reliably tied through fasteners, horizontal wall-connecting steel pipes, and internal and external vertical poles near the main nodes of the external scaffolding.

[0003] When dismantling the external scaffolding, the horizontal wall-connecting steel pipes and fasteners need to be removed simultaneously, and the vertical steel pipes embedded in the floor need to be cut off. The steel pipes are removed by gas cutting, which makes it impossible to recover the steel pipes embedded in the concrete at the tie points, resulting in loss of the steel pipes. When building the external walls, scaffolding holes are left because the embedded vertical steel pipes and fasteners occupy the wall position. After the wall connection parts are removed, workers need to be rearranged to seal them. The workload is large and labor-intensive, which affects the progress of the scaffolding dismantling and is prone to cracking and leakage in the scaffolding holes filled later. Utility Model Content
