Problems solved by technology

[0002] On construction sites, such as construction sites such as bridges and highways, construction equipment such as steel ladders is required. The steel ladders in the prior art are heavy, inconvenient to disassemble, take a long time, and have a low turnover rate. The safety net increases the wind blocking area of ​​the frame, and the stability and strength need to be improved

Embodiment 1

[0019] like Figure 1-2 As shown, an assembled steel ladder includes a steel ladder body 1, the bottom of which is a bottom bracket 2, the top of the bottom bracket 2 is connected with a single structural unit 3, and the outside of the single structural unit 3 is connected with a The door that opens to the inside and outside, the single structure unit 3 is connected with the main structure unit 8, and the outside of the main mechanism unit 8 is connected with a ladder 6, and the ladder 6 is provided with evenly arranged pedals 7, and the ladder 6 on the adjacent floor A horizontally arranged operating platform 9 is provided at the intersection of the two, and a horizontal connecting rod 11 is arranged on the operating platform 9, and an operating panel 10 that can be opened downward is arranged in the middle of the adjacent horizontal connecting rod 11. The opened operating panel 10 is For the stairs used by construction personnel to go up or down, the end of the operating pan...

Embodiment 2

[0021] like Figure 1-3 As shown, a prefabricated steel ladder includes a steel ladder body 1, and the lower part of the steel ladder body 1 is a bottom support 2, which firmly connects the structure of the steel ladder body 1 with the foundation, transfers the upper load to the foundation, and the bottom support 2 The upper part of the structure is connected with a single structural unit 3, which is the basic unit. Each standard segment is composed of two single-section welded structures connected by intermediate connecting rods, which mainly play the role of forming the main body of the structure. After hanging standard ladders and horizontal jumps on it, personnel can pass freely up and down, and arrive at the construction work place. The outside of the single structural unit 3 is connected with a door that can be opened to the inside and the outside, and each section of the single structural unit 3 is provided with 2 doors, and the door is connected with the operation pane...

Abstract

A prefabricated type steel ladder is technically characterized by comprising a steel ladder body, a bottom layer support is arranged at the lower portion of the steel ladder body, a single-body structure unit is connected with the upper portion of the bottom layer support, the outer face of the single-body structure unit is connected with a door capable of being opened inwards and outwards; the single-body structure unit is connected with a main body structure unit, ladder bodies are connected with the outer side of the main body structure unit, a transverse operation platform is arranged at the intersection of the ladder bodies of every two adjacent layers, a horizontal connecting rod is arranged on each operation platform, and an operation plate capable of being opened downwards is arranged between every two adjacent horizontal connecting rods; the operation plates can be used as the ladder allowing a constructor to climb up and down after being opened; bolts are arranged at the ends of the downwards-opened sides of the operation plates; the bolts and the horizontal connecting rods are locked when the operation plates are not opened downwards; turning plate supports are arranged on the two sides of the steel ladder body. By means of the technical scheme, the prefabricated type steel ladder is convenient and rapid to install and detach and capable of being repeatedly used; no safety net needs to be hung outside, the wind resistance area is effectively narrowed, and the anti-tilt stability of the structure is improved.

Description

technical field [0001] The invention relates to the technical field of building auxiliary equipment, in particular to an assembled steel ladder. Background technique [0002] On construction sites, such as construction sites such as bridges and highways, construction equipment such as steel ladders is required. The steel ladders in the prior art are heavy, inconvenient to disassemble, take a long time, and have a low turnover rate. The safety net increases the wind-blocking area of ​​the frame, and the stability and strength need to be improved. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the above technologies, and provide an assembled steel ladder for this purpose. [0004] An assembled steel ladder, comprising a steel ladder body, the lower part of the steel ladder body is a bottom bracket, the upper part of the bottom bracket is connected with a single structural unit, and the outside of the single structural uni...
