Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a positioning device for a scaffold vertical pole on an I-beam. Background Technique

[0002] A scaffold is a temporary construction tool set up at a construction site for workers to operate, aiming to solve the problems of vertical and horizontal transportation. It is mainly used for exterior walls, interior decoration, or places with relatively high storeys, so that construction workers can work up and down, or conduct peripheral safety maintenance and high-altitude installation of components.

[0003] The traditional method of positioning and fixing the scaffold vertical pole on a cantilevered steel beam is to weld steel bar heads on the cantilevered steel beam. This method will cause irreversible damage to the cantilevered steel beam itself. When the cantilevered steel beam is reused, generally the original steel bar heads cannot be utilized, and the steel bar heads need to be cut and welded repeatedly, which is time-consuming, laborious and costly; the frequent damage and repair of the rust-proof layer of the cantilevered steel beam will greatly shorten its service life; on-site high-altitude welding operations, high-altitude operations and welding open-flame operations all have relatively large safety hazards, increasing the difficulty of on-site management.

An installation through hole is opened through the top of the support limiting steel plate. The connecting steel plate is located at the bottom of the I-shaped steel beam on the side away from the bending structure. A second connection through hole corresponding to the first connection through hole is opened through the connecting steel plate.
