Abstract

The invention provides a vertical rod fixing piece comprising a fixing sleeve, a fixing rod and a fastening assembly. An inner cavity of the fixing sleeve can be connected with the outer contour of anI-shaped steel cantilever beam in attached and sleeving modes. The fastening assembly is arranged on the fixing sleeve and used for firmly mounting the fixing sleeve on the exterior of the I-shaped steel cantilever beam. The fixing rod is welded to the fixing sleeve and used for inserting and fixing a vertical rod of a scaffold. According to the vertical rod fixing piece, by using the fixing sleeve with the welded fixing rod, the situation that the fixing rod is directly welded to the I-shaped steel cantilever beam is avoided, and the damage hidden danger of the I-shaped steel cantilever beamand the fixing rod in construction operation due to stress concentration is reduced; during mounting and demounting, an I-shaped steel cantilever beam without a welded fixing rod can penetrate through a shear wall independently, the aerial operation procedures are simplified, and the construction risks are reduced; and meanwhile, the collision deformation risk of scaffold parts in the process that the scaffold parts are stored and transported to other sites is also avoided. On the basis of the vertical rod fixing piece, the invention further provides the scaffold.

Description

technical field

[0001] The invention relates to the technical field of construction equipment, in particular to a pole fixing piece and a scaffold. Background technique

[0002] Cantilevered scaffolding refers to the scaffolding structure unloaded on the rigid cantilever beam (frame) attached to the building structure. It is used for the main body or decoration project in construction and its safety protection needs. The erection height shall not be greater than 20m.

[0003] In the prior art, the structure of the vertical pole positioning part at the end of the cantilever beam of the cantilevered scaffold is: a steel bar with a diameter of 20 mm and a height of 200 mm is welded at a distance of 100 mm from the center line of the flange above the end of the I-beam cantilever beam. . The scaffolding pole is inserted on the steel bar to play the role of fixing the pole. Weld a steel bar with a diameter of 20mm and a height of 100mm at a distance of 100mm from the center lin...
