Description

Technical Field

[0001] This invention relates to the field of suspended platform technology, and specifically to a suspended platform construction device based on the outward tilting of the curved curtain wall of an airport control tower. Background Technology

[0002] In the field of modern architecture, airport control towers, as iconic buildings with special functions and architectural forms, often pursue uniqueness and innovation in their design, with the application of outward-tilting hyperboloid curtain walls becoming increasingly common. This complex curtain wall structure can give airport control towers a unique appearance and aesthetic value, but it also brings great challenges to construction. Currently, when facing outward-tilting hyperboloid curtain walls like those of airport control towers, traditional suspended scaffolding installations result in varying distances between the scaffolding and the structural edge on each floor. In particular, the distance is too large at the "waist" of the middle floors of the control tower, failing to meet construction requirements. To address these issues, we propose a construction device based on outward-tilting suspended scaffolding for curved curtain walls of airport control towers. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a construction device for an outward-tilting suspended platform based on the curved curtain wall of an airport control tower, which solves the problems mentioned in the background art.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A construction device for an outward-tilting suspended platform based on the curved curtain wall of an airport tower includes: a suspended platform body, with positioning rings fixedly connected to both the left and right sides inside the suspended platform body, and a main rope movably sleeved inside the positioning rings; an auxiliary rope, which is movably sleeved inside the positioning rings, and both the auxiliary rope and the main rope are movably installed together with the suspended platform body, with mounting rings fixedly connected to the top ends of both the auxiliary rope and the main rope; and a diagonal pull component, which is disposed outside the main rope and used to pull the main rope.

[0005] By adopting the above technical solution and setting up a cable tie, the cable tie can pull the main rope, thereby adjusting the distance between the suspended basket body and the "waist" of the middle floor of the tower.

[0006] Preferably, the inclined pull component includes: a fixing ring fixedly connected to the outer wall of the main rope, and a pull rope fixedly connected to the outer wall of the fixing ring; at least three tensioners, all of which are fixedly connected to the outside of the pull rope, the pull rope being equipped with an automatic tensioning cylinder; and a separating member disposed on the outside of the auxiliary rope for separating the main rope from the auxiliary rope. The automatic tensioning cylinder enables automatic tensioning.

[0007] By adopting the above technical solution and setting a separator, the main rope and the auxiliary rope can be separated, thereby avoiding the main rope and the auxiliary rope from getting tangled together and causing accidents.

[0008] Preferably, the separating component includes: a connecting ring, the connecting ring being fixedly connected to the outer wall of the auxiliary rope, a separating tube being fixedly connected to one end of the connecting ring, and one end of the separating tube being fixedly connected to the outer wall of the fixing ring.

[0009] By adopting the above technical solution and setting up the suspended platform body, after the workers fix the top surface of the auxiliary rope and the main rope to the top of the tower, the suspended platform body can be sent to the waist of the tower by using the auxiliary rope and the main rope together.

[0010] Preferably, a fixing rope is movably installed inside the pulling rope, and one end of the fixing rope is fixedly connected to an anchor.

[0011] By adopting the above technical solution, by setting anchors and connecting the anchors to the middle part of the tower, and then connecting the pulling rope to the fixed rope, and using a rope tensioner to tighten the pulling rope, the pulling rope can pull the auxiliary rope and the main rope to move, thereby adjusting the distance between the suspended platform body and the tower's waist, thus facilitating the workers to carry out construction work on the tower from the suspended platform body.

[0012] Preferably, a tension sensor is fixedly connected to the top surface of the positioning ring, and the tension sensor is movably installed together with the main rope. Two tilt sensors are fixedly connected to the bottom surface of the suspended basket body.

[0013] By adopting the above technical solution, a tension sensor can be set up to monitor the tension between the main rope and the suspended basket body in real time, and an inclination sensor can be set up to monitor the inclination angle of the suspended basket body.

[0014] Preferably, a baffle plate is fixedly connected to the outer wall of the main rope.

[0015] By adopting the above technical solution, by setting baffles, the baffles can limit the maximum height of the suspended platform body's movement. By setting connecting rings, and by using the connecting rings in conjunction with the separation pipes, the auxiliary ropes and main ropes can be separated, thereby avoiding accidents caused by accidental entanglement between the auxiliary ropes and main ropes.

[0016] Preferably, the tension sensor, tilt sensor, and automatic cylinder deactivation device are all electrically connected to the control module, and the control module is connected to the monitoring terminal via a network module.

[0017] In summary, the present invention has the following main beneficial effects: By setting up the suspended platform, after the workers fix the top of the auxiliary rope and the main rope to the top of the tower, the suspended platform can be sent to the waist of the tower through the cooperation of the auxiliary rope and the main rope. By setting up anchors and connecting the anchors to the middle part of the tower, the pulling rope is connected to the fixed rope. At the same time, the pulling rope is tightened with a rope tensioner, so that the pulling rope can pull the auxiliary rope and the main rope to move, thereby adjusting the distance between the suspended platform and the waist of the tower, which makes it easier for workers to carry out construction work on the tower from the suspended platform. By installing tension sensors, the tension between the main rope and the suspended platform can be monitored in real time. By installing tilt sensors, the tilt angle of the suspended platform can be monitored. By installing baffles, the maximum height of the suspended platform can be limited. By installing connecting rings, which work in conjunction with separation tubes, the auxiliary ropes can be separated from the main ropes, thereby preventing accidents caused by accidental entanglement between the auxiliary and main ropes.

A main rope 3 is movably sleeved inside the positioning rings 2, and a secondary rope 4 is movably sleeved inside the positioning rings 2. Both the secondary rope 4 and the main rope 3 are movably installed together with the suspended platform body 1. Installation rings 5 ​​are fixedly connected to the top of both the secondary rope 4 and the main rope 3. An inclined tension component is provided on the outside of the main rope 3. The main rope 3 is used to pull the inclined pull component, which includes a fixed ring 6. The fixed ring 6 is fixedly connected to the outer wall of the main rope 3.

[0024] Example 1: Construction of a moderately tilted glass curtain wall for a new control tower at a medium-sized airport I. Project Overview A new air traffic control tower is being built at a medium-sized international airport. The tower is 60m high, with the 30-50m section consisting of an outward-tilting curved curtain wall structure (maximum outward tilt angle of 15°). The curtain wall is made of double-layered insulated tempered glass (each piece weighs 80kg). The project requires curtain wall installation, sealant application, and subsequent cleaning. The construction area is approximately 800㎡.

[0025] II. Specific Configuration of the Device Suspended platform body: adopts ZLP630 electric suspended platform, rated load capacity 630kg, equipped with 2 sets of anti-tilt safety locks (trigger angle ≤3°), adjustable horizontal support installed at the bottom (adjustment range ±50mm), and adapted to 15° outward curved surface; Main and auxiliary ropes: The main rope is made of Φ16mm galvanized steel wire rope (breaking strength ≥180kN), and the auxiliary rope is made of Φ14mm galvanized steel wire rope (breaking strength ≥120kN). Each rope is 65m long (with a 5m allowance for exceeding the tower height). The inclined cable component consists of three Φ20mm fixing rings (1.5m apart) fixed to the outer wall of the main rope, and the pulling rope is a Φ12mm polyester fiber rope (tensile strength ≥50kN). It is equipped with three manual rope tensioners (adjustable stroke 0-500mm). Separator: A Φ18mm connecting ring is welded to the outer wall of the auxiliary rope. The separation tube is a Φ30mm stainless steel tube (800mm in length), with both ends welded to the connecting ring and the main rope fixing ring, respectively, to ensure that the distance between the main and auxiliary ropes is ≥700mm and to avoid tangling. Monitoring and limiting components: Two tension sensors (range 0-50kN, accuracy ±0.1%) are installed on the top surface of the positioning ring, and two tilt sensors (range ±10°, accuracy ±0.1°) are installed on the bottom surface of the basket. A Φ30mm steel baffle is fixed 5m from the top of the main rope (limiting the maximum working height to 55m). Anchoring components: The mounting ring is a Φ50mm stainless steel ring (welded and fixed to the pre-embedded parts at the top of the tower), and the anchor is a mechanical anchor bolt (fixed to the concrete corbel at a height of 40m on the tower, with an anchoring force ≥80kN). III. Construction Implementation Steps Device installation: First, fix the installation ring to the embedded part at the top of the tower, insert the main and auxiliary ropes and lower it to the ground; connect the basket body to the main and auxiliary ropes through the positioning ring, install the tension sensor and tilt sensor and calibrate them; drill holes at the 40m height concrete corbel to install the anchor, connect the pull rope to the anchor, and pre-tighten the pull rope through the rope tensioner. Commissioning and Verification: The suspended platform is raised to a height of 10m, and the horizontal support is adjusted to ensure that the platform's levelness is ≤0.3°. The main rope tension change is simulated (with a 300kg load), and the alarm threshold of the tension sensor (set to 40kN) is confirmed to trigger normally. The tilt sensor is adjusted so that the safety lock is triggered when the tilt angle is ≥2°, verifying the locking reliability. Formal Operation: Workers enter the suspended platform and raise it to the starting position on the 30m outward-tilting curved surface. The length of the pulling rope is adjusted using the rope tensioner (pausing for 10 seconds every 50mm adjustment to ensure stable force), maintaining a 300mm distance between the platform and the curtain wall. During operation, the tension (main rope tension controlled at 25-35kN) and tilt angle (≤1.5°) are monitored in real time. The baffle limits the platform's maximum height to 55m (avoiding equipment at the top of the tower). Work completion: After a single section of work is completed, slowly lower the basket to the ground, check the wear of the main and auxiliary ropes (wear ≤10%), and after confirming that the rope tensioner and the separating tube are not deformed, move to the next work section and repeat the above steps.

[0026] IV. Implementation Results This embodiment involved the use of two devices, and the entire construction was completed in 15 days. During the construction process, there were no accidents involving the main and auxiliary ropes getting tangled. The maximum tilt angle of the suspended platform was 0.8° (lower than the safety lock trigger value), the tension monitoring error was ≤0.5kN, and the verticality deviation of the curtain wall installation was ≤2mm / m, which met the requirements of the "Technical Specification for Safety of High-Altitude Operations in Building Construction".

[0027] Example 2: Construction of a heavily tilted metal curtain wall for the control tower of a large hub airport expansion project. I. Project Overview The renovation and expansion project of a large international hub airport tower involves the original tower height of 80m. The 45-75m section will be transformed into a heavily outward-tilted curved curtain wall (maximum outward tilt angle of 25°). The curtain wall material is aluminum-magnesium-manganese metal composite panel (each panel weighs 120kg). The project requires the demolition of the old curtain wall, the installation of the new curtain wall, and anti-corrosion treatment. The construction area is approximately 1200㎡.

[0028] II. Specific Configuration of the Device Suspended platform body: The enhanced ZLP630 suspended platform is selected (load capacity increased to 700kg), the anti-tilt safety lock is upgraded to dual trigger mode (mechanical + electronic), the horizontal support adjustment range is expanded to ±80mm, and it is compatible with 25° outward curved surfaces; Main and auxiliary ropes: The main rope is Φ18mm galvanized steel wire rope (breaking strength ≥220kN), and the auxiliary rope is Φ16mm galvanized steel wire rope (breaking strength ≥160kN). The rope length is 90m (with a 10m safety allowance). The cable tie components are as follows: four Φ22mm fixing rings (1.2m apart) are fixed to the outer wall of the main rope; the pulling rope is a Φ14mm aramid rope (tensile strength ≥80kN); and four hydraulic rope tensioners are configured (adjustable stroke 0-800mm, with pressure self-locking function). Separation components: The connecting ring is a Φ20mm alloy ring (welding strength ≥50kN), the separation tube is a Φ35mm seamless steel pipe (length 1000mm), rubber buffer sleeves are installed at both ends, and the distance between the main and auxiliary ropes is ≥900mm; Monitoring and limiting components: tension sensor range 0-80kN (accuracy ±0.05%), tilt sensor range ±15° (accuracy ±0.05%), baffle is a double-layer steel structure (Φ40mm, fixed at 8m from the top, maximum limiting height 72m). Anchoring components: The mounting ring is welded to the steel structure at the top of the tower (welding length ≥ 100 mm), and the anchor is a hydraulic expansion anchor rod (fixed on the steel structure support at a height of 55 m on the tower, with an anchoring force ≥ 120 kN).

[0029] III. Construction Implementation Steps Enhanced installation: Before installation, survey the curved surface of the tower section from 45-75m and mark the points where the outward tilt angle changes; perform non-destructive testing (UT testing) after welding the installation ring; apply special wire rope grease after threading the main and auxiliary ropes; and conduct a pull-out test (load 100kN and hold for 10 minutes without displacement) after the anchor is installed. Precise Adjustment: When the suspended platform is raised to a height of 20m, the horizontal level is adjusted to ≤0.2° using horizontal supports; simulating metal plate hoisting conditions (loading a 600kg weight), the tension sensor alarm threshold is set to 50kN and the tilt sensor alarm threshold to 1.8°; the hydraulic tensioner is adjusted to ensure that the tension change is ≤2kN for every 100mm adjustment; graded operation: the outward-curved surface is divided into 3 sections according to angle (45-55m: 15°, 55-65m: 20°, 65-75m: 25°), and the tensioner is adjusted before each section to maintain a 400mm distance between the suspended platform and the curtain wall (to meet the space requirements for metal plate installation); when removing the old curtain wall, the load change is monitored by the tension sensor (to avoid sudden overload), and the tilt sensor provides real-time feedback on the suspended platform's posture, automatically decelerating when the angle exceeds 1.5°; Dynamic maintenance: Before daily operations, check the welded joints of the separator pipe (no cracks) and the tensioner pressure (maintain 80% of the rated pressure). Replace the worn section of the pull rope every 5 sections of operation (replace when the wear is ≥5%). Calibrate the sensor once a week.

[0030] IV. Implementation Results This embodiment involved the deployment of 3 devices, and the renovation was completed in 22 days. During the operation of the heavily outward tilt section (25°), the maximum tilt angle of the suspended platform was 1.2°, the main rope tension was stable at 35-45kN, and there were no safety lock triggering records. The flatness deviation of the metal curtain wall installation was ≤1.5mm / m, and the anti-corrosion treatment coverage was 100%, meeting the requirements of the "Construction and Acceptance Specifications for Visual Navigation Aids at Civil Airports". The construction efficiency was improved by 30% compared with the traditional suspended platform.
