Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a suspended platform and construction method for irregular roof structures. Background Technology

[0002] Traditional suspended platforms for high-altitude operations are installed on flat, regular horizontal roof structures. In such conventional environments, the platform's supports can be placed stably, counterweights can be neatly stacked, and safety ropes can be easily attached to solid anchor points. However, with the diversification of modern architectural aesthetics, numerous irregularly shaped roof structures with curved, sloping, wavy, or other complex geometric forms have emerged, posing a challenge to the application of traditional suspended platforms.

[0003] On irregularly shaped roofs, the rigid support base of traditional suspended scaffolds struggles to fully conform to the curved or sloping surface, resulting in severely insufficient installation stability and posing significant safety hazards such as slippage or even overturning. Furthermore, the fixed counterweight stacking method is highly prone to slippage on slopes, compromising the overall anti-overturning moment. Simultaneously, irregularly shaped roofs often lack continuous and reliable rigid anchor points, making it difficult to install safety ropes—a lifeline—and even when installed, their effectiveness is often reduced due to poor angles or increased friction. These inherent defects not only lead to cumbersome installation processes, difficult debugging, and low construction efficiency, but also fundamentally constitute serious safety hazards, greatly limiting the application of suspended scaffold technology in various innovative building types.

[0004] Therefore, there is an urgent need in this field for a suspended platform system and its supporting construction method that can fundamentally adapt to the special structure of irregular roofs, ensuring convenient, stable, reliable and safe installation. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a suspended platform and construction method for irregularly shaped roof structures. This suspended platform effectively solves the challenges of installing and using a suspended platform on irregularly shaped roofs through a modular adaptive suspension mechanism, a track-type safety rope system, and an intelligent leveling system.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A suspended platform for irregular roof structures includes a suspension mechanism, a suspension platform, a hoist, a safety lock, and a steel wire rope. The suspension mechanism includes a front support, a rear support, a front beam, a middle beam, and a rear beam. The bottom of the front support and the rear support are both provided with universal adjustment bases that can adjust the angle with multiple degrees of freedom. The rear support is provided with a modular interlocking counterweight system.

[0008] As an improvement of the present invention, the universal adjustment base includes a base plate, a spherical hinge, and a support base. The spherical hinge is disposed between the base plate and the support base and is provided with a damping locking mechanism for locking the angle.

[0009] As an improvement of the present invention, the modular interlocking counterweight system includes several counterweight blocks. Each counterweight block has a mating structure on its upper and lower surfaces and a locking rod that passes through the central through hole of all counterweight blocks. The bottom end of the locking rod is locked by a nut.

[0010] As an improvement of the present invention, a flexible track-type safety rope system is also included. The flexible track-type safety rope system includes an annular guide rail, a sliding hanger, and a safety rope. The annular guide rail is fixed to the roof, the sliding hanger is slidably disposed on the annular guide rail, and the top end of the safety rope is attached to the sliding hanger.

[0011] As an improvement of the present invention, the annular guide rail is fixed to the roof by several adjustable height brackets, and the sliding bracket includes a pulley block and a safety ring.

[0012] As an improvement of the present invention, it also includes an intelligent tilt control system, which is installed on the suspended platform and includes a tilt sensor and a controller. The hoist is a variable frequency speed control motor. The controller receives the signal from the tilt sensor and outputs a control signal to the hoist to adjust its running speed.

[0013] The present invention also provides a method for constructing a suspended platform for irregularly shaped roof structures, using the aforementioned suspended platform and including the following steps:

[0014] S1: Roof Survey and Simulation: Obtain 3D point cloud data of irregular roofs and build models, and simulate the layout of suspended platform installation schemes in the models;

[0015] S2: Install a track-type safety rope system: Based on the model positioning, install a circular guide rail and sliding hanger on the roof, and attach the safety rope;

[0016] S3: Install the adaptive suspension mechanism: Place the front and rear brackets with universal adjustment bases on the roof and adjust the angle to fit the roof, then lock them; install the interlocking counterweight and fix it with the locking rod;

[0017] S4: Assembly and Electrical Connection: Install suspension beams, wire ropes, suspended platform, hoist and safety lock; connect electrical wiring and intelligent tilt control system;

[0018] S5: System integration and debugging: Conduct no-load and load tests to verify the automatic leveling function of the intelligent tilt control system.

[0019] As an improvement of the present invention, in step S1, the three-dimensional point cloud data is acquired by a three-dimensional laser scanner and imported into BIM software to establish an information model.

[0020] As an improvement of the present invention, in step S3, when adjusting the universal adjustment base, a digital level is used to assist in measurement to ensure that the front beam is in a preset slightly tilted state.

[0021] As an improvement of the present invention, in step S5, an off-center load test is performed, and the tilted suspension platform is automatically adjusted to a horizontal position by the intelligent tilt control system, and the adjustment response time and accuracy are recorded.

[0022] The beneficial effects of this invention are as follows:

[0023] The core of this invention lies in its adaptive suspension mechanism: the universal adjustable base, through a ball joint structure and damping lock, achieves full-angle contact between the support and the roof surface, ensuring effective load transfer and fundamentally overcoming the risks of traditional supports being unstable and prone to slippage on inclined surfaces. The modular interlocking counterweight, through a concave-convex interlocking structure and pre-tightening with the central tie rod, integrates the dispersed counterweight blocks into a whole, effectively resisting the instability torque caused by the slippage of individual counterweight blocks on an inclined roof. Simultaneously, the track-type safety rope system, through a pre-set annular guide rail and sliding hanger, provides workers with a continuous and reliable flexible guide rail, ensuring that the safety rope attachment point is always directly above the work point, avoiding friction between the safety rope and the roof edge, and eliminating safety hazards caused by insufficient or improperly installed fixing points.

[0024] This invention achieves active leveling and precise control of the construction platform through an integrated intelligent sensing and control system. The built-in tilt sensor and the variable frequency speed-regulating lifting mechanism form a closed-loop control system that monitors the suspended platform's posture in real time. When subjected to external disturbances (such as changes in roof shape or uneven load), it automatically adjusts the speed difference between the two lifting mechanisms to dynamically maintain the platform's level. This function reduces reliance on operator experience, transforming the traditional "manual observation-intervention" leveling mode into an automated "real-time sensing-active control" mode. This not only improves the construction quality and efficiency of processes such as curtain wall installation and sealing, but also reduces the risk of materials slipping due to platform tilt, enhancing the stability and controllability of the operation process.

[0030] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0031] Example 1

[0032] This embodiment provides a suspended platform for irregularly shaped roof structures, such as... Figure 1 As shown, the system mainly includes an adaptive suspension mechanism, a suspended platform, a flexible track-type safety rope system, and an intelligent tilt control system. These modules work together to achieve safe, stable, and automated construction operations on irregularly shaped roofs.

[0033] Both the front and rear supports of the adaptive suspension mechanism are equipped with universal adjustment bases at their bottoms. Each universal adjustment base consists of a base plate, a spherical hinge, a support seat, and a damping locking mechanism. Preferably, the contact surface between the base plate and the irregularly shaped roof is lined with a neoprene anti-slip pad with a static friction coefficient of not less than 0.6. The spherical hinge allows the support seat to deflect at all angles within a range of ±15°. By tightening the handwheel of the damping locking mechanism, a locking torque of not less than 150 N·m can be provided, securely locking the support at any angle adapted to the roof curvature.

[0034] The rear support is equipped with a modular interlocking counterweight system. The system consists of several counterweight blocks, locking rods, and clamping nuts. Preferably, the upper and lower surfaces of the counterweight blocks have trapezoidal interlocking structures. The locking rods pass through the central through-holes of all counterweight blocks, and their bottom ends are pre-tightened by high-strength nuts. The pre-tightening force F of the locking rods must meet the following conditions:

[0035]

[0036] in:

[0037] F is the preload (N) that needs to be applied to the locking lever.

[0038] μ is the static friction coefficient between the counterweight and the support branch pipe, which is taken as 0.15;

[0039] N is the total weight of the counterweight (N);

[0040] k is the safety factor, which is not less than 2.0 according to GB19155 "High-altitude Suspended Platforms".

[0041] Tighten the nuts with a torque wrench according to the calculated value to ensure that the counterweight as a whole has no risk of slipping on the sloping roof.

[0042] The flexible track-type safety rope system includes a circular guide rail, a sliding hanger, and a safety rope. The circular guide rail is fixed to the roof structure via an adjustable height bracket. The sliding hanger includes a pulley system and a safety ring, allowing it to slide freely along the guide rail. The top of the safety rope is attached to the safety ring, and the bottom is for workers to connect their safety belts, forming continuous fall protection that moves with the suspended platform.

[0043] The intelligent tilt control system includes tilt sensors, a controller, and a variable frequency hoist. The tilt sensors are installed at both ends of the suspended platform to monitor the platform's tilt angle θ in real time. The controller receives the sensor signals and uses a PID control algorithm to output control signals to the variable frequency hoist.

[0044] The control algorithm is as follows:

[0045] The controller input is the tilt angle deviation. ,in The horizontal angle is set to 0°. The controller output is the speed compensation amount Δv, calculated using the following formula:

[0046]

[0047] in, , , These are the proportional, integral, and derivative coefficients, respectively. The speeds of the two hoists are adjusted independently. , This enables the platform to dynamically and automatically level itself.

[0048] Example 2

[0049] This embodiment provides a construction method based on the above-mentioned suspended platform system, such as... Figure 2 As shown, it includes the following steps:

[0050] S1. Install the flexible track-type safety rope system on the roof. Based on the path simulated in the BIM model, install the circular guide rail and sliding hanger, and lower the safety rope.

[0051] S2. Install the adaptive suspension mechanism. Place the front and rear brackets with universal adjustment bases at the predetermined support points, adjust the base angle so that the front beam is in a slightly tilted-up position of 1.5° to 2.5°, and calibrate using a digital level. Then, lock the bases and install the modular interlocking counterweight system, using a torque wrench to ensure that the preload of the locking rod is within the specified range.

[0052] S3. Assemble the suspended platform, hoist, and safety lock, and thread the steel wire ropes through them. Connect all electrical wiring for the intelligent tilt control system and perform a preliminary power-on check.

[0053] S4. Perform system integration and debugging. Conduct no-load operation, a static load test at 125% of rated load (remaining stationary for 15 minutes), and an off-center load test sequentially. In the off-center load test, verify whether the intelligent tilt control system can adjust the tilt angle caused by a 150kg off-center load to within the range of |θ| < 0.5° within 5 seconds.

[0054] S5. After successful commissioning, the suspended platform is put into normal use. During construction, the intelligent tilt control system operates continuously to maintain the platform's level; the flexible track-type safety rope system provides dynamic fall protection throughout the entire process.

[0055] S6. Archive the daily inspection data of the suspended platform, the leveling system operation log, and the final acceptance documents to form a complete digital archive of the suspended platform installation and use for subsequent query and traceability.

[0056] It should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. For those skilled in the art, several improvements and modifications can be made on the basis of the above embodiments without departing from the principle of the present invention, and all such improvements and modifications fall within the scope of protection of the claims of the present invention.
