Description

Technical Field

[0001] The utility model belongs to the field of disc-type scaffolding, and in particular relates to a disc-type scaffolding crossbar set with a variable length. Background Art

[0002] Scaffolding systems are widely used in the construction of housing, roads, railways and other projects, providing construction workers with an operating platform and forming a safe and reliable working environment. The convenience, safety and stability of its erection will directly affect the construction efficiency and the safety of the construction site. As a new type of tool-based support system, the disc-type scaffolding has been vigorously promoted in recent years for its good overall stability, easy erection and dismantling, material saving and environmental protection, and beautiful frame.

[0003] Since the accessories of the disc-type scaffolding are modular and standardized in production and construction, their fixed models and specifications lead to poor flexibility in the erection of the frame and limited scope of application. The standard lengths of the crossbars of the disc-type scaffolding are 300mm, 600mm, 900mm, 1200mm, etc., which are difficult to adapt to the complex and changeable actual conditions of the construction site, and the frames outside the modular range cannot be erected normally. Utility Model Content

[0005] The utility model provides the following technical solutions: a variable-length disc-type scaffolding crossbar set, comprising an outer crossbar, an inner crossbar and a bolt, wherein two inner crossbars are connected with the outer crossbar at both sides of the outer crossbar by sockets; the inner crossbar is provided with connecting holes along its length direction, the connecting holes penetrate the inner crossbar, and the outer crossbar is provided with a first positioning hole and a second positioning hole, the first positioning hole and the second positioning hole are located on both sides of the inner crossbar and are aligned with any one of the connecting holes on the inner crossbar, the bolt passes through the first positioning hole, the connecting hole of the inner crossbar is screwed with the second positioning hole; the ends of the two inner crossbars away from the outer crossbar are connected with plugs.

[0006] Furthermore, the connecting hole penetrates along the radial direction of the inserted cross bar.

[0007] Furthermore, a through hole is provided on the outer sleeve cross bar, a pad is welded on the outer wall of the outer sleeve cross bar at the through hole, the screw hole on the pad serves as a second positioning hole, and the bolt passes through the through hole of the outer sleeve cross bar and is screwed into the second positioning hole.

[0008] Furthermore, the bottom surface of the pad is a curved surface that fits with the outer wall of the outer sleeve cross bar.

[0009] Furthermore, the hole spacings of the connecting holes on the inserted crossbar are equal.

[0010] Compared with the prior art, the advantages of the present invention are:

[0011] The utility model provides a variable-length disc-type scaffolding crossbar set, which has a wide range of length adjustment and can adapt to different erection spacing requirements of the disc-type scaffolding; the operation is simple, and the purpose of quickly adjusting the length of the crossbar set can be achieved by changing the hole position of the connecting hole where the bolt is inserted into the inner crossbar after the bolt is pulled out; the crossbar set can be adjusted in length in both directions, the adjustment is flexible, and the on-site versatility is strong.
