This kind of climbing ladder step has a relatively simple structure and is relatively convenient for maintenance and repair, and has been widely applied to various inspection wells, water towers, subway tunnels, etc.

[0003] Traditional prefabricated climbing ladder steps for steel pipe scaffolds generally adopt measures such as building with steel pipes and fasteners or purchasing finished products for installation. When installing, relevant components need to be connected through a drilling tool. This process is not only cumbersome in operation and low in work efficiency, but also a large amount of smoke and dust will be generated when drilling rigid materials, which will affect the lives of residents. Content of the Utility Model

[0004] The purpose of the utility model is to provide a prefabricated climbing ladder step for a steel pipe scaffold, which effectively solves problems such as low erection and demolition efficiency and single procurement specifications when adopting measures such as building with steel pipes and fasteners or purchasing finished products, and is prone to cause low erection and demolition efficiency of the climbing ladder and poor civilized construction.

[0005] To achieve the above purpose, a prefabricated climbing ladder step for a steel pipe scaffold is provided, which includes a first support frame and a second support frame. Both the first support frame and the second support frame are provided with a plurality of installation holes. A climbing ladder step body is installed between the first support frame and the second support frame. Connection columns are fixedly connected to both vertical parallel sides of the climbing ladder step body. A detachable connection component is arranged between the installation hole of the first support frame and one of the connection columns, and the other connection column is slidably installed in the installation hole of the second support frame.

[0006] As a further improvement of this technical solution, the connection component includes a connection cylinder connected in the installation hole of the first support frame. Threads for connection are provided at both ends of the connection cylinder. The connection cylinder is composed of a pair of arc plates. A screw for limiting is arranged in the middle of the pair of arc plates. One of the connection columns is threadedly connected to the connection cylinder.

[0007] As a further improvement of this technical solution, a fixing nut is threadedly connected to the outside of the other connection column, and the nut is located outside the second support frame.

[0008] As a further improvement of this technical solution, the climbing ladder step bodies are linearly and evenly distributed between the first support frame and the second support frame.

[0009] As a further improvement of the technical solution, the main body of the ladder step is composed of a pair of right-angle frames and a plurality of fixing columns, and a pair of connecting columns are fixedly connected to the outer sides of the two right-angle frames, and a plurality of fixing columns are fixedly connected between the pair of right-angle frames.

[0010] Compared with the prior art, the beneficial effects of the present utility model are:

[0011] For the prefabricated ladder step of the steel pipe scaffolding, by providing threads in the installation holes of the first support frame, the connecting component can quickly thread-connect one of the connecting columns of the ladder step body with the installation hole of the first support frame. By thread-connecting a nut for fixation on the outer side of the other connecting column, it is connected to the second support frame. The combination and installation procedures of the entire device avoid punching and other settings, not only improving the installation efficiency of the device, but also facilitating subsequent disassembly.
