Problems solved by technology

[0002] At present, there are many kinds of scaffolding used on construction sites, among which portal scaffolding and bowl-buckle scaffolding are more commonly used: portal scaffolding is shaped like a door and is welded, and multiple portal frames can be built to form a bent frame. Not only is the structure more complicated, but the position of the center nail of the diagonal tie rod is easy to break, the supporting strength is poor, and the installation and disassembly are more dangerous; moreover, its large shape makes it inconvenient to transport
Bowl buckle scaffolding is simpler in structure and better

Embodiment Construction

[0021] The scaffolding of the present invention includes a vertical bar 1 and a cross bar 2. The vertical bar 1 is provided with a connecting piece 3 for connecting the cross bar 2 at a certain distance, the cross bar 2 is connected with the connecting piece 3 from top to bottom, and the upper part of the connecting piece A clip 4 that prevents the cross bar 2 from coming out upwards is provided.

[0022] The above-mentioned clip can be a screw 401 (such as Figure 1-4 ).

[0023] Above-mentioned clip also can be the lock ring 402 that is arranged on the top of connector 3, and the upper end of lock ring has spiral slope 5, and its lower end face clamps and presses cross bar 2, and vertical rod is also provided with spiral slope 5 phase wedges. The limit pin 6 of the lock ring 402 is provided with a vertical through hole 7 that is arched outwards so that the lock ring can slide up and down (such as Figure 5-8 ).

[0024] Above-mentioned clip also can be the clasp 403 t...

Abstract

The invention relates to a scaffold which comprises vertical bars and cross bars. The scaffold is characterized in that the vertical bar is provided with connecting components which are arranged at a certain interval and used for connecting the cross bars, the cross bars are in mortice and tenon joint with the connecting components from up to down, and the upper part of the connecting component is provided with a clamp unit for preventing the cross bar from separating upwards. The scaffold provided by the invention has the advantages that through setting the clamp unit for preventing the cross bar from separating upwards at the upper part of the connecting component, the cross bar connected with the connecting component can not be separated from the connecting component, thereby avoiding the potential safety hazards existing in the utilization of the scaffold.

Description

technical field [0001] The invention relates to a novel scaffold. Background technique [0002] At present, there are many kinds of scaffolding used on construction sites, among which portal scaffolding and bowl-buckle scaffolding are more commonly used: portal scaffolding is shaped like a door and is welded, and multiple portal frames can be built to form a bent frame. Not only is the structure more complicated, but the position of the center nail of the diagonal tie rod is easy to break, the supporting strength is poor, and the installation and disassembly are dangerous; moreover, its large shape makes it inconvenient to transport. Bowl buckle scaffolding is simpler in structure and better in strength than portal scaffolding, but it mainly relies on the cooperation of bowl buckle welded on the column and the hook of the cross bar to form a bent frame. Its structure is still more complicated, with more parts and relatively low cost. At the same time, it is easy to cause in...
