Device for automatically adjusting horizontal expansion, retraction and torsion of external lifting scaffold and construction method

Abstract

The invention relates to a device for automatically adjusting horizontal expansion, retraction and torsion of external lifting scaffold and a construction method. The device for automatically adjusting horizontal expansion, retraction and torsion of external lifting scaffold comprises an adjusting plate and four bolts, wherein cross stiffening processing is performed on the back surface of the adjusting plate, and the whole height is 8-10 mm, the adjusting plate is enabled to cover two adjacent basic unit frame scaffold plates and is fixed on one basic unit frame scaffold plate in a two-sided manner through one bolt, and a hinging point is formed; other three bolts are fixed on the two basic unit frame scaffold plates in one sided manner, and the three extended bolts are used for limiting the adjusting plate in the cross stiffened position of the back surface of the adjusting plate; and contacts of other three bolts and the adjusting plate are limit points. By means of one-point hinge and three-point limitation, the horizontal protective safety of adjusting gaps of the lifting scaffold is guaranteed, investment of labor and material resources is also reduced, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a special-shaped horizontal connecting plate of an external climbing frame of a building and a construction method, and is especially suitable for an automatic adjustment device for horizontal expansion and twisting of the connecting plate of the external climbing frame. Background technique [0002] With the rapid development of the economy, super high-rise buildings have developed from regular shapes to multi-body curved surfaces. All-steel external climbing frames are widely used in the facade protection of super high-rise buildings due to their many advantages. The connection of basic unit scaffolding boards cannot meet the requirements of building expansion and torsion adjustment. Even if horizontal protective coverage is added to basic unit scaffolding boards, there will be staggered gaps, and at the same time, the consumption of labor and materials will be increased.
