Description

Technical Field

[0001] The utility model relates to the field of scaffolds, in particular to a flap-type scaffold. Background Art

[0002] At present, scaffolding operation is an important part of construction activities. Regarding the protection measures for scaffolding ladders and the holes on the edges of the ladders at the working platform, the scaffolding specification "ST / T 3555--2014" has corresponding requirements:

[0003] 1. Within the first and second steps of the scaffolding, the straight ladder can be set on the outside of the scaffolding; (corresponding to the straight ladder entering and exiting the working platform, a hole is set at the edge.)

[0004] 2. Regarding the protection requirements for the holes on the side of the vertical ladder at the working platform: "The vertical ladder should be equipped with a movable guardrail at the exit of each working platform, and the movable guardrail should have at least two cross bars.

[0005] There are the following problems:

[0006] 1. The specification requires that "movable guardrails (at least two horizontal bars) be set up at the edge holes", but there is a lack of description of technical details. This makes specific implementation difficult, and the existing solutions are complex in structure and poor in practicality.

[0007] 2. Due to the lack of a good solution, protective measures for edge holes have been missing. Safety inspectors of various companies have always regarded it as a blind spot and turned a blind eye to it. The safety risk of workers falling from high edges always exists. Utility Model Content

[0008] The purpose of the utility model is to provide a flap type scaffolding in view of the above-mentioned shortcomings.

[0009] The utility model comprises a scaffold body which is assembled by a group of horizontal bars and a group of vertical bars. A supporting plane is arranged in the scaffold body, a manhole is opened on the supporting plane, and a pair of door panels for opening or closing the manhole are arranged on the supporting plane.

[0010] The supporting plane is composed of a group of horizontal scaffolding boards and a group of vertical scaffolding boards. A group of horizontal scaffolding boards are arranged in sequence and laid in the scaffolding body, and a group of vertical scaffolding boards are laid above the horizontal scaffolding boards. The angle between the horizontal scaffolding boards and the vertical scaffolding boards is a manhole.

[0011] One end of the door panel is located on the vertical scaffolding board, and the other end of the door panel is located on the cross bar of the scaffolding body.

[0013] The A rotation limit ring and the B rotation limit ring are both made of iron wire. Multiple groups of through holes are respectively opened on the door panel, the horizontal scaffolding board and the vertical scaffolding board. The A rotation limit ring is installed in the corresponding through holes on the door panel and the vertical scaffolding board. One of the B rotation limit rings is installed in the corresponding through holes on the door panel and the horizontal scaffolding board, and the other B rotation limit ring passes through the through hole of the horizontal scaffolding board and is wrapped around the scaffolding body.

[0014] A hook is arranged on the cross bar of the scaffold body above the door panel, and one of the opened door panels is hooked by the hook to keep the door panel in the open state.

[0015] The hook is made of iron wire, one end of the hook is wound around the crossbar of the scaffold body, and the other end of the hook is inserted into the through hole of the door panel.

[0026] The supporting plane 2 is composed of a group of horizontal scaffolding boards 4 and a group of vertical scaffolding boards 5. A group of horizontal scaffolding boards 4 are arranged in sequence and laid in the scaffolding body 1, and a group of vertical scaffolding boards 5 are laid above the horizontal scaffolding boards 4. The angle between the horizontal scaffolding boards 4 and the vertical scaffolding boards 5 is a manhole.

[0027] One end of the door panel 3 is located on the vertical scaffolding board 5, and the other end of the door panel 3 is located on the crossbar of the scaffolding body 1. The front and rear ends of the door panel 3 are respectively placed on the vertical scaffolding board 5 and the crossbar, which ensures the support strength of the door panel 3.

[0028] One end of a pair of door panels 3 is movably mounted on the vertical scaffolding board 5 through the A rotating limit ring 6, the other end of the door panel 3 close to the horizontal scaffolding board 4 is movably mounted on the horizontal scaffolding board 4 through the B rotating limit ring 7, and the other end of the door panel 3 away from the horizontal scaffolding board 4 is movably mounted on the scaffolding body 1 through the B rotating limit ring 7.
