Wheel button type scaffold

Abstract

The invention discloses a wheel button type scaffold which comprises a plurality of support rods and cross bars, wherein wheel button discs are arranged on the vertical rods; plugging ports are formed in the wheel button discs; and plugging boards are arranged at the end parts of the cross bars and are plugged into the plugging ports to connect the cross bars with the vertical rods. According to the wheel button type scaffold, the wheel button discs are used as intermediate connecting members and the cross bars are allowed to be plugged into the plugging ports to form a staggered structure of the vertical rods and the cross bars. Therefore, the assembly of the scaffold can be finished by simple plugging work; and the wheel button type scaffold is stable and reliable in structure and can be repeatedly used. The wheel button type scaffold disclosed by the invention is suitable for house and bridge scaffold projects and can be used for a support frame of a template and other temporary platform supports and the like and is a multifunctional scaffold.

Description

technical field [0001] The invention relates to a scaffold used in civil construction engineering. Background technique [0002] At present, there are many types of scaffolding used in construction sites, among which portal scaffolding, bowl-buckle scaffolding and disc-buckle scaffolding are more commonly used. [0003] Portal scaffolding is shaped like a door, and multiple doors can be built to form a bent frame. The structure is not only complicated, any change in the size of the frame requires another type of mast and its accessories, the cross support is easy to break at the middle hinge point, the shaped scaffolding is heavy, the support strength is poor, and installation and removal are difficult. It is more dangerous, and its shape is large, and it occupies a large area for stacking, so it is inconvenient to transport.

AI Technical Summary

Problems solved by technology

The structure is not only complicated, any change in the size of the frame requires another type of mast and its accessories, the cross support is easy to break at the middle hinge point, the shaped scaffolding is heavy, the support strength is poor, and installation and removal are difficult. It is more dangerous, and its shape is large, it takes up a large area for stacking, and it is inconvenient to transport

[0004] Bowl-buckle scaffolding is simpler in structure than door-type scaffolding, and its strength is better, but it mainly relies on the cooperation of bowl buttons welded on the columns and the hooks of the crossbars to form a bent frame. The loss of parts is relatively expensive, and it is easy to cause injury to the operator during installation and disassembly

The crossbars of the bowl button scaffolding are shaped rods of several sizes, which limits the size of the frame and lowers the work efficiency; secondly, it also has design defects, such as the damage of one of the crossbars to the vertical poles, resulting in the The connection node between the vertical pole and the horizontal pole is loose, which brings a huge safety hazard to the use

[0005] The buckle-type scaffolding is more convenient to overlap, but when the buckle falls off when it is removed, it is easy to cause deformation, and the number of maintenance is more, resulting in a low reuse rate
