Description

Adjustable hand rack with wall foot and use method Technical Field The invention relates to the field of building exterior protection scaffold erection construction, in particular to an adjustable wall foot connecting hand frame and a use method thereof. Background In the building construction process, the scaffold is an indispensable temporary facility, and the stability of the scaffold is directly related to the construction safety. The wall connecting piece is used as a key connecting component between the scaffold and the main building structure, and has the main functions of reliably connecting the scaffold with the main building structure, transmitting horizontal load and preventing the scaffold from being unstable or capsized under the action of horizontal force. The traditional wall connecting piece is usually fixed with the building main body by adopting a pre-buried steel pipe or a rear anchor bolt and the like, and then is connected with the scaffold vertical rod through a fastener. However, in actual construction, due to factors such as construction errors of a main structure of a building, accumulated deviation of scaffold erection and the like, the distance between the wall connecting piece and the scaffold upright rod is often mismatched, and connection is difficult or impossible. At this time, constructors often adopt nonstandard modes such as forcibly prying the frame body, adding cushion blocks and the like to treat, so that the stress performance of the wall connecting piece is affected, and potential safety hazards are brought to the overall stability of the scaffold. In addition, traditional even wall spare can't exert initiative pretightning force to the scaffold frame, when the scaffold frame takes place horizontal deformation or produces the displacement in the use, is difficult to carry out effectual pullback correction.
