Description

Technical Field

[0001] The invention belongs to the technical field of construction platforms and relates to a construction operation platform, in particular to a detachable steel structure construction operation platform. Background Art

[0002] With my country's vigorous promotion of green buildings and prefabricated buildings, high-strength, fire-resistant and weather-resistant steel structure housing buildings with the characteristics of green buildings and prefabricated buildings have developed rapidly. However, most of the on-site high-altitude construction technologies and safety measures of steel structures still remain in the traditional structural form.

[0003] The frame system in steel structure projects is generally manually erected using on-site cut steel pipes and fasteners. This leads to problems such as non-standard components, low erection and dismantling efficiency, and stability that relies heavily on workers' experience. The load-bearing capacity is limited, and wooden gangplanks are prone to aging and cracking, posing a risk of falling from height.

[0004] Early modular platforms: Although partially standardized, they still have significant defects: the use of plug-in connections results in weak resistance to lateral displacement of the nodes; the platform plates and load-bearing beams are fixed by welding, which damages the galvanized layer and causes rust, shortening the service life.

[0005] At the same time, it is impossible to achieve full modular on-site assembly and aerial installation of standard section components to meet the practical needs of different scenarios.

[0006] Based on this, we propose a detachable steel structure construction operation platform. Summary of the Invention

Secure the base assembly 1 to the ground. 3. Install the snap-fit ​​seat 11 on the top of the support column 10. The support column 10 and the insertion hole 12 are used to install the standard section assembly 2.

[0068] Step 2, Installation of the Standard Section on the First Floor: 1. Positioning and Docking: Hoist the standard section assembly 2, insert its bottom plug-in connecting column 16 into the base plug-in hole 12; align the connecting plate 18 with the snap-fit ​​seat 11 and snap it into place; 2. Quick Locking: Operate the quick locking assembly 8: tighten the smooth section of the locking half screw 59 through the hole of the connecting plate 18; press down the hinged rod 2 56 to pre-tighten → tighten the locking nut 60 to complete the rigid connection;

[0069] Step 3: Stacking Standard Sections: Interlayer Docking: Insert the plug-in connection column 16 of the upper standard section assembly 2 into the plug-in hole 22 of the lower section; snap the connection plate 18 into the lower connection socket 20, and tighten the process as above; 2.

[0070] Step 4, top platform assembly installation: top platform plug-in connecting column 2 46 is inserted into top standard section plug-in hole 22; connecting plate 2 48 is snapped into connecting clamp 20 → fast locking assembly 8 is locked; safety reinforcement: X-shaped reinforcement rod 2 45 resists horizontal force; top platform fence 51 is installed on the periphery of top platform frame 50;

[0071] Step 5, ladder system installation: step onto the platform ladder assembly 7: the joint plate 1 28 is fixed to the base side frame through the quick locking assembly 8; connect the ladder assembly 5: the joint plate 2 68 is locked on both sides to the ladder mounting seat 1 25 / ladder mounting seat 2 26 / ladder mounting seat 3 / ladder mounting seat 4.

[0072] 2. Lifting and Sectioning Process

[0073] Step 1, initial positioning: the lifting assembly clamps the top standard section, and the guide wheel 38 is close to the column and crosses the avoidance wheel area 27;

[0074] Step 2, jacking preparation: retract the support rod hydraulic rod 41 → lift the support rod 35 out of the frame and close it against the blocking rod 34; manually snap the support seat 43 into the lower locking point;

[0075] Step 3, jacking execution: jacking hydraulic rod 42 extends → support seat 43 presses down → jacking assembly rises as a whole including load-bearing rod 39;

[0076] Step 4, temporary support: the support rod hydraulic rod 41 extends → the jacking support rod 35 is unfolded and pressed against the standard section frame 15;

[0077] Step 5, install the new section: hoist the new standard section assembly 2 to the load-bearing rod 39 → manually adjust → insert the connecting column 16 into the plug-in hole 22 → quickly lock;

[0078] Step 6, system reset: retract the support rod hydraulic rod 41 → lift the support rod 35 out of the frame, retract the lifting hydraulic rod 42 → lift the assembly down to the top clamp of the new standard section;

[0079] Step 7: Complete the single-section raising cycle and prepare for the next lifting.

[0080] The operating procedures of the quick locking assembly 8 are as follows: 1. Insertion and positioning: the smooth section of the locking half screw 59 passes through the hole of the connected part, such as the connecting plate 18; 2. Lever pre-tightening: pressing down the hinged rod 2 56 → the lever amplifies the force → the locking half screw 59 is pulled upward to generate clamping force; 3. Thread locking: tightening the locking nut 60 → pressing the base plate 54 and the connected part → double anti-loosening: locking nut + locking nut.

[0081] 4. Disassembly process: 1. Disconnection: Loosen the quick-locking assembly 8 → Disassemble the ladder, top platform, and standard section from top to bottom; 2. Recover the lifting assembly: Retract the hydraulic rod → Remove the clamping frame; 3. Base removal: Remove the diagonal support rod 14 → Lift off the base body 9.

[0082] In summary, the platform adopts a fully modular design. All components can be prefabricated in the factory and assembled on site like building blocks through the quick locking component 8. Its original lever half-screw locking technology allows one person to complete a single-node rigid connection, improving the tightening efficiency. Combined with the hydraulic jacking and sectioning component 3, the aerial installation of a single-section standard section component 2 can be completed safely in a short time, completely solving the bottleneck of high-altitude manual operation efficiency.

[0083] X-shaped reinforcement rods 24 and 45 cooperate to resist horizontal deformation, and the cross-reinforced connecting rod assembly 6 rigidly transmits lateral forces between floors, thereby improving the platform's wind load resistance. Zero-risk jacking: The jacking process is driven by a hydraulic system, which is stable and efficient, and workers do not need to work in the air at all times. The ladder assembly 5 and the platform ladder assembly 7 are connected and cooperate with ladder guardrail 1 31 and ladder guardrail 2 65 to form an enclosed safe aisle, with an accident rate close to zero.

[0084] The components can be quickly disassembled and transported; the base component 1, standard section component 2, lifting and adding section component 3, top platform component 4, connecting ladder component 5, reinforcing connecting rod component 6, and platform ladder component 7 can all be reused, reducing costs; the height can be freely expanded by increasing or decreasing the number of standard sections to adapt to different scenarios such as bridge towers and power plant chimneys, and the single project utilization rate is industry-leading.
