Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction equipment, in particular to a folding and avoiding mechanism for a walking board of an attached lifting scaffold. Background Art
[0002] An attached lifting scaffold is fixed to a high-rise or super-high-rise engineering structure through an attached support structure, and uses its own lifting equipment and devices to climb layer by layer with the construction of the engineering structure until after the structure is capped. When the requirements for exterior wall decoration operations are met, it can descend layer by layer. Compared with the traditional cantilever scaffold, the attached scaffold is more firm and stable, can reduce the sway caused by external factors such as wind, and effectively improve the sense of security of workers and the stability during operation.
[0003] When a high-rise or super-high-rise building structure is being built, a tower crane is installed to transfer materials. In order to ensure the stability of the tower crane, a cross brace is set between the tower crane support and the building structure to improve the stability of the tower crane through the cross brace. However, the problem is that the cross brace of the tower crane will block the normal lifting of the lifting scaffold. Therefore, when the lifting scaffold is lifted to the position of the cross brace, the walking boards inside the lifting scaffold need to be removed layer by layer at the corresponding position, and then reinstalled after the climbing frame passes through the cross brace. The installation and disassembly operations are relatively troublesome, affecting the climbing and positioning efficiency of the lifting scaffold, and there are safety hazards in frequent high-altitude operations, which need to be improved. Summary of the Utility Model

The walking board is composed of multiple square plate bodies connected end to end. At the position corresponding to the cross brace of the tower crane support on the walking board, there is a notch. At both ends of the notch, there are folding plates hinged on the end face of the walking board. After the two folding plates are in a horizontal state, the outer ends of the two just butt to form a closed plane. The width dimension formed by the horizontal butt of the two folding plates is the same as the length dimension of the notch. An inclined stay wire is connected to the outer end of the folding plate. The inclined stay wire is required to have a high tensile strength. The upper end of the inclined stay wire is connected to the square frame support between the upper and lower walking boards. After the inclined stay wire is tightened, the folding plate is in a horizontal state. The folding plate and the walking board form a complete walking channel, and an adjusting mechanism is provided between the inclined stay wire and the folding plate.

[0007] Preferably, two diagonal stay wires are provided between the folding plate and the square frame support. The diagonal stay wires, the U-shaped hanger and the folding plate form a right triangle structure. The lower ends of the two diagonal stay wires are connected to the two corners at the end of the folding plate.
[0008] Preferably, an auxiliary baffle that can be turned up and down is hinged to the side surface of the walkway board, and meshes for draining rainwater can be provided on the surface of the walkway board.
[0009] Preferably, the folding plates in each layer of the walkway board are arranged corresponding to each other up and down.
[0010] Preferably, a protective net is provided outside the walkway board. The protective net is formed by butting a plurality of protective net plates. There are gaps at the positions of the protective net corresponding to the cross braces and the notches on the walkway board.

DETAILED DESCRIPTION
[0020] Example 1, see the attached specification Figure 1-2 The folding and avoiding mechanism of the walkway plate of an attached lifting scaffold comprises a walkway plate 12 arranged at a medium interval on the scaffold body, the walkway plate is a walking working channel for construction workers, and a notch is provided at a position corresponding to the cross brace 11 of the tower crane support. The notch is an avoiding notch, and folding plates 13 hinged on the end surface of the walkway plate are respectively provided at both ends of the notch. The width dimension formed by the horizontal butt joint of the two folding plates 13 is the same as the length dimension of the notch, and the folding plates in each layer of the walkway plate 12 are arranged correspondingly up and down, and an inclined wire 14 is connected to the outer end of the folding plate 13. Under the action of the inclined wire 14, the folding plate 13 can only be folded upward, and the upper end of the inclined wire is connected to the square frame bracket 15 between the upper and lower walkway plates 12, and the frame bracket 15 provides pulling support for the inclined wire, and after the inclined wire 14 is tightened, the folding plate 13 is in a horizontal state.
[0021] There are two inclined cables 14 between the folding plate 13 and the square frame bracket 15. The lower ends of the two inclined cables are connected to the two corners of the end of the folding plate 13. The double cables can provide the folding plate with a pulling force of sufficient strength and stability to ensure its stability.
[0022] The side of the walkway board 12 is hinged with an auxiliary baffle 17 that can be folded up and down. In order to ensure the smooth lifting operation of the lifting scaffolding, a certain gap will be set between the lifting scaffolding and the building body. Building materials and other debris will fall from the gap. Therefore, the auxiliary baffle 17 that can be folded up and down is designed. It is folded up during lifting and then lowered to support it on the wall at an angle after lifting.
[0023] A protective net 19 is provided on the outside of the walkway board 12. Gaps are provided at positions corresponding to the protective net, the cross brace 11 and the notch on the walkway board 12. A gap that passes through the protective net and the cross brace 11 can be provided at positions corresponding to the protective net and the cross brace 11. During the construction process, there is no need to install or remove the protective net. The gap has little effect on the protection quality. The protective net 19 can also be reinstalled after lifting and avoiding to form all-round protection.
[0024] The walkway plate 12 and the folding plate 13 are hinged via hinges, and the hinges are hinged between the upper surfaces of the walkway plate and the folding plate.
[0025] The diagonal stay wire 14 is a steel wire rope, and a plastic layer is coated on the steel wire rope. The plastic layer plays an anti-corrosion effect on the steel wire rope and can avoid the phenomenon that the diagonal stay wire scratches the construction workers.
[0026] When the avoidance mechanism is in use, the diagonal stay wire 14 provides a horizontal pulling force for the folding plate 13, so that the folding plate 13 is in a stable horizontal state and docks with the walkway plate 12 to form a complete scaffolding walking operation passage. When the scaffolding is lifted past the cross brace of the tower crane, the folding plate 13 can be turned up to enable the scaffolding to avoid the cross brace 11. After passing the cross brace, the folding plate 13 can be turned down to be horizontally docked with the walkway plate 12 again, and the avoidance operation of the scaffolding can be completed simply and efficiently.
[0027] Embodiment 2, see the attached instruction Figure 3-4 , on the basis of Embodiment 1, an adjusting mechanism is provided between the diagonal stay wire 14 and the folding plate 13. The adjusting structure includes a U-shaped hanging bracket 16 fixedly connected to the end of the upper surface of the folding plate. The U-shaped hanging bracket is not only used for hanging the diagonal stay wire 14, but also can form a reinforcing rib on the surface of the folding plate 13 to improve the structural strength of the folding plate 13. A plurality of hanging holes 162 are equidistantly arranged along the length direction of the side rod 161 of the U-shaped hanging bracket. The diagonal stay wire 14 passes through the hanging holes, and a retaining piece 163 or a retaining rod is provided at the end of the diagonal stay wire 14 extending out of the hanging hole 162 to hang the diagonal stay wire 14 on the side rod 161.
[0028] During the use of the folding plate 13, due to the trampling of construction workers or the influence of other external forces, the levelness will become poor, resulting in the unevenness of the walking operation passage formed by the walkway plate 12 and the folding plate 13. At this time, by adjusting the hanging position of the lower end of the diagonal stay wire 14 on the hanging hole 162, the folding plate 13 can be conveniently and quickly readjusted to the horizontal position, restoring the flatness of the walking operation passage and ensuring the construction safety.
