Description

Technical Field

[0001] The present invention relates to the technical field of building construction, in particular to a hoisting platform for building construction. Background Art

[0002] In the field of construction, especially in high-altitude operations such as curtain wall installation and roof construction of high-rise buildings, hoisting platforms are key equipment to ensure construction safety and efficiency. The hoisting platforms in the existing technology generally have the following shortcomings: Insufficient structural stability: Traditional steel keel frames mostly use single-specification pipes, which are prone to deformation under uneven load distribution or wind loads. Due to insufficient keel stiffness, the maximum deflection of the platform exceeds the specification limit, posing a risk of overturning.

[0003] Incomplete safety protection measures: The safety rope often shares a fixed point with the platform hanging system. Once the platform structure fails, the safety rope is easily implicated. In addition, the height of the guardrail is generally less than 1.5m, which cannot effectively prevent people from falling.

[0004] Low installation and disassembly efficiency: When moving the existing platform, all components must be disassembled and rely on manual handling. For example, in a certain project case, it took 4 hours to move an 8m×8m platform, which seriously affected the construction progress.

[0005] Poor wire rope fixing reliability: Insufficient number of wire rope clamps or improper installation leads to sliding failure. For example, in an accident, there were only two wire rope clamps, causing the platform to fall.

[0006] In response to the above problems, the present invention provides a safer and more efficient hoisting platform for construction by optimizing structural design, strengthening safety protection and standardizing construction technology. Summary of the Invention

[0007] In view of the deficiencies in the prior art, the present invention provides a hoisting platform for construction, which solves the problems raised in the above-mentioned background technology.

[0008] Technical Solution: To solve the above technical problems, according to one aspect of the present invention, more specifically a hoisting platform for construction, comprising a steel keel frame, a zipper assembly, a protective structure and a connecting assembly; The steel keel frame includes a main keel and a secondary keel. The main keel is made of F60×3.7-4 square steel tube, and the secondary keel is made of Φ48.3×3.0 round tube. The main keel and the secondary keel are welded or connected by fasteners to form a frame structure. The zipper assembly includes a hanging steel wire rope and a supporting steel wire rope. The hanging steel wire rope is a Φ16mm steel wire rope, which is set at the four corners and the middle of the four sides of the steel keel frame to suspend the steel keel frame to the main steel structure of the building. The supporting steel wire rope is a Φ12mm steel wire rope to enhance the stability of the steel keel frame. The protective structure includes a guardrail and a scaffolding board. The guardrail is not less than 1.5m high and is arranged around the steel keel frame. The scaffolding board is laid on top of the steel keel frame. The connecting assembly includes a wire rope clamp and a steel component. The wire rope clamp is used to fix the hanging wire rope and the supporting wire rope. The steel component is welded to the steel beam of the hanging wire rope to prevent the hanging wire rope from sliding.

[0009] Furthermore, the size of the steel keel frame is 8100mm×8100mm or 8100mm×4400mm.

[0010] Furthermore, the breaking force of the hanging steel wire rope is not less than 144 kN, and the breaking force of the supporting steel wire rope is not less than 86.3 kN.

[0011] Furthermore, the number of the wire rope clamps is no less than 3, and the rope clamp buckles the clamp seat on the working section of the wire rope, and the U-bolt is buckled on the tail section of the wire rope.

[0012] Furthermore, it also includes a safety rope, which is made of Φ16mm nylon rope and is independently fixed to the roof structure for workers to hang safety belts.

[0013] Furthermore, the scaffolding board is made of scaffolding steel mesh and is tied and fixed to the secondary keel with steel wire.

[0014] Furthermore, the construction process of the present invention is as follows: S1. Ground assembly of the hoisting platform: complete the welding of the steel keel frame on the ground, connect the steel cables and supporting components on the lower side of the platform, install the handrail poles and crossbars around it, lay the scaffolding steel mesh and fix it to the scaffolding, and hang the platform and the main steel structure with φ16 steel wire rope; S2. Platform crane installation: After the platform is assembled on the ground and accepted by the supervision unit, it is lifted by a tower crane. The tower crane is connected to the four lifting rings in the middle of the platform and lifted to the installation height. The four corner lifting rings of the platform are fixed to the main frame steel beams through steel wire ropes. The tower crane ropes are removed, and the four lifting rings in the middle of the platform are fixed to the main frame steel beams through steel wire ropes. S3. Operation and Use: After the platform and the main frame steel beams are installed and fixed, and after passing the inspection by the supervision unit, the workers enter the platform to carry out curtain wall installation. A maximum of 5 people can work on each platform at the same time. The curtain wall materials are evenly placed on the platform. Workers working on the platform wear a five-point double-hook safety belt and hang on the safety rope; S4. Move or dismantle: When the installation of the curtain wall inside the platform is completed, report to the project department and the supervision unit for approval and then move the platform. Connect and fix the tower crane rope through the four lifting rings in the middle of the platform, cut the wire ropes at the eight hanging points on the platform, and hoist the platform to the ground by the tower crane. Use a manual hydraulic pallet truck on the ground to move the platform to the position ready for lifting. After the project department and the supervision unit have re-accepted the platform and it is hoisted and installed to the next position; when dismantling the platform, hoist the platform to the ground and remove the horizontal connection between the vertical steel structure of the platform and the main steel structure, the connecting wire rope between the platform and the main steel structure, the flat steel mesh on the platform, the platform handrail, the steel cable on the lower side of the platform and the supporting structure in sequence.

[0015] The beneficial effects of the hoisting platform for construction of the present invention are: (1) The present invention has a strong structural stability. The main keel adopts F60×3.7-4 square steel tube, and the secondary keel adopts Φ48.3×3.0 round tube. The frame structure is formed by welding or fastener connection, which enhances the overall rigidity of the frame.

[0016] In the zipper assembly, hanging steel wire ropes are set at the four corner points and the middle positions of the four sides of the steel keel frame. The supporting steel wire ropes are used to enhance stability, effectively resist uneven load distribution and wind loads, and reduce the risk of deformation and overturning.

[0017] (2) The present invention has perfect safety protection, and the height of the guardrail is not less than 1.5m, which can effectively prevent people from falling.

[0018] The safety rope is made of Φ16mm nylon rope and is independently fixed to the roof structure to avoid sharing the same fixing point with the platform hanging system. Even if the platform structure fails, the safety rope will not be affected, providing reliable safety protection for the operators.

[0019] The scaffolding boards are made of scaffolding steel mesh and are fixed to the secondary purlins with steel wire to ensure that the scaffolding boards are stable and prevent workers from stepping on empty space.

[0020] The wire rope is fixed reliably, the number of wire rope clamps is not less than 3, and they are installed in accordance with specifications. The rope clamp buckles the clamp seat on the working section of the wire rope, and the U-bolt is buckled on the tail section of the wire rope, effectively preventing the wire rope from sliding and failing.

[0021] The steel parts are welded to the steel beams of the hanging wire ropes, which further prevents the hanging wire ropes from sliding and improves the reliability of the connection.

[0022] (3) The present invention has high installation and disassembly efficiency. During the construction process, after the platform is assembled on the ground, it is lifted by a tower crane, and the installation process is simple and fast.

[0023] When moving the platform, it is lifted to the ground using a tower crane and moved using a manual hydraulic pallet truck, eliminating the need to disassemble all components. This significantly shortens moving time and improves construction efficiency. For example, the time required to move an 8m×8m platform was significantly reduced from the traditional four hours. The specific time was not specified, but efficiency has been significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS
