Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bridge pier column construction, in particular to a kind of installation of auxiliary pier column construction's hanging type foldable operation platform in scaffold. BACKGROUND

[0002] Scaffold refers to the various supports that are erected at construction sites to enable workers to carry out operations and solve vertical and horizontal transportation, and we need to erect scaffold to provide a working platform for workers at higher places on construction site where direct construction is not possible. When carrying out bridge pier column construction, scaffold needs to be erected to provide safety protection and working platform for steel bar binding, formwork disassembly and construction. After conventional scaffold erection is completed, it needs to maintain a certain distance from pier column to facilitate formwork hoisting, disassembly and worker auxiliary operations.

[0003] However, if the distance between scaffold and pier column is too large, worker directly standing on scaffold to carry out operations is very inconvenient, and there is a great risk of falling, which has great security risks. Therefore, a platform capable of being erected between scaffold and pier column to facilitate worker operations and avoid falling is needed. SUMMARY

Detailed Implementation

[0016] The technical solutions of the invention will be clearly and completely described below with reference to the embodiments. The described embodiments are only a part of the present utility model, and not all of the embodiments. Example

[0017] A hanging, foldable work platform installed on scaffolding includes a longitudinal frame 3, connecting struts 5, and a transverse panel frame 7. The top of the longitudinal frame 3 is welded with multiple hooks 1 for attaching to the horizontal bars of the scaffolding 2. The longitudinal frame 3 is also equipped with cross-shaped fasteners 4 for connecting to the vertical bars of the scaffolding 2. The bottom end of the longitudinal frame 3, away from the scaffolding 2, is hinged to one end of the transverse panel frame 7 via hinges 6. The hinges 6 include hinge ears and hinge shafts, ensuring that the transverse panel frame 7 can rotate within a 0-90 degree range around the hinges 6. To improve the hinge's stability, multiple hinges are used, i.e., multi-point hinged connections. Connecting struts 5 are hinged between the other two sides of the transverse panel frame 7 and the two sides of the longitudinal frame 3 for extending and retracting the transverse panel frame 7. The connecting struts 5 primarily function to extend and retract the work platform. After retracting, the transverse panel frame 7 can be secured by binding to prevent it from naturally unfolding. When installing the work platform, the hooks are suspended from the horizontal bars of the scaffolding, and the horizontal bars of the longitudinal panels are connected and fixed to the uprights of the scaffolding using cross couplers.

[0018] The longitudinal frame 3 includes a square longitudinal outer frame 10. Horizontal bars 8 and vertical bars 9 are connected within the longitudinal frame 3. Cross couplers 4 connect the horizontal bars 8 to the vertical bars of the scaffolding 2. The cross couplers 4 are standard couplers used in the construction industry and are purchased and used commercially. There is at least one horizontal bar 8, and the number of vertical bars 9 and hooks 1 is determined according to the length of the working platform.

[0019] The horizontal panel frame 7 includes a square horizontal outer frame 15, within which longitudinal beams 16 and transverse beams 17 are connected. The top surface of the horizontal outer frame 15 is provided with a panel 13 for standing on during work. There is at least one transverse beam 17, the number of longitudinal beams 16 is determined according to the length of the work platform, and the panel size is determined according to the size of the work platform.

[0020] The connecting strut 5 includes a first connecting strut 11 and a second connecting strut 14. One end of the first connecting strut 11 and one end of the second connecting strut 14 are hinged together by a hinge shaft 12. The other end of the first connecting strut 11 is hinged to the longitudinal frame 3, and the other end of the second connecting strut 14 is hinged to the transverse panel frame 7.

[0021] The work platform is initially in a folded state. After being moved to the installation site, it is slowly lowered along the outside of the scaffolding, allowing the hooks to be engaged with the horizontal bars of the scaffolding. Cross couplers are then used to connect the horizontal bars of the longitudinal panels to the vertical bars of the scaffolding, locking them securely. Once the connection between the work platform and the scaffolding is secure and without wobbling, the cable ties are loosened, and the work platform is unfolded, ensuring the horizontal panels are level. Workers can then stand on the work platform to begin operations.

[0022] The above description is not intended to limit the present utility model, nor is the present utility model limited to the above examples. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
