Description

Technical Field

[0001] This invention relates to the field of building component technology, specifically to a ring track hoisting device for inward-tilting glass curtain walls in super high-rise buildings and its construction method. Background Technology

[0002] In the process of rapid development of my country's construction industry, distinctive glass curtain walls have become the main exterior surface of modern skyscrapers. Complex and varied curtain wall forms and shapes are increasingly favored. However, the unique and complex exterior curtain walls bring increased installation technical difficulty and higher quality requirements.

[0003] In existing technologies, the hoisting of curtain wall unit panels mainly includes methods such as suspended scaffolding installation, external scaffolding installation, mobile crane installation, jackhammer installation, and circular track hoisting. Among these, the circular track hoisting method has become a commonly used hoisting method in building curtain wall construction due to its advantages such as vertical transportation and horizontal movement, large load-bearing capacity, high safety factor, less impact from severe weather such as strong winds, fast construction speed, and high hoisting accuracy. This method involves setting up a circular track under cantilevered arms that are fixed to the floor slab and extend beyond the floor level, with the circular track parallel to the curtain wall installation surface. Electric hoists are installed on the circular track to lift the glass curtain wall panels and move them parallel to the building. However, when the building facade is an inwardly sloping facade, existing technologies typically maintain a considerable distance between the curtain wall panels and their installation location to prevent collisions between the panels and the building structure during hoisting. Since the glass curtain wall panels can only move horizontally along a circular track and cannot move along the building's interior, this distance makes installation difficult. Furthermore, manual traction results in uneven movement speed and stress on the panels, increasing the risk of deflection and collisions at heights. For ultra-heavy and ultra-large glass curtain wall panels, manual traction is insufficient, requiring specialized machinery and increasing construction costs. Additionally, with conventional circular tracks, the cables and control devices connecting the electric hoist cannot move synchronously with the track. Operators must manually hold the cables and control devices while moving with the hoist, which is inconvenient and poses safety risks when moving near edges. When the curtain wall installation height exceeds the roof slab height, conventional circular tracks laid at the roof slab edge are insufficient for hoisting the highest-floor glass curtain wall. Therefore, how to use a circular track to hoist glass curtain wall panels when the building facade is an inwardly sloping facade, how to make the cables connecting the electric hoist and the control device connection lines move synchronously with the curtain wall circular track without manual intervention, and how to use a circular track to hoist unit panels when the curtain wall installation height exceeds the roof floor height are problems that need to be solved in the field of curtain wall construction. Summary of the Invention

[0004] The technical problem to be solved by this invention is to overcome the difficulties in the existing technology of hoisting ultra-high-rise inward-tilting glass curtain walls, and to provide a ring track hoisting device and its construction method for ultra-high-rise inward-tilting glass curtain walls.

[0005] The technical solution adopted by this invention to solve its technical problem is: a ring track hoisting device for ultra-high-rise inward-tilting glass curtain walls, comprising:

[0006] The support arm is mounted on the floor slab and is used for load-bearing.

[0007] A circular track is provided below the support arm.

[0012] The second hanging ear plate is fixed to the upper floor slab with bolts;

[0013] The first cantilever arm is provided with several locking steel sleeves on its exterior, and the locking steel sleeves are fixed to the lower floor slab by bolts.

[0014] Furthermore, the support arm includes a second cantilever arm, a cross-shaped steel sleeve disposed outside the second cantilever arm, a T-shaped steel sleeve disposed outside the cantilever arm, a front steel column vertically inserted through the cross-shaped steel sleeve, a rear steel column vertically inserted through the T-shaped steel sleeve, a bottom steel plate disposed at the lower end of the front steel column, and a diagonal tie steel tube disposed between the front steel column and the second cantilever arm;

[0015] The bottom steel plate is fixedly connected to the roof floor slab by bolts;

[0016] The cross-shaped steel sleeve is bolted to the front steel column, and the T-shaped steel sleeve is bolted to the rear steel column.

[0017] Furthermore, the support arm also includes a fixed steel sleeve disposed at the bottom of the rear steel column, a support pad disposed on one side of the fixed steel sleeve, a concrete counterweight frame disposed at the top of the support pad, and a grouting steel pipe connected to the top of the concrete counterweight frame.

[0018] The support pad is fixedly connected to the roof floor slab by bolts.

[0019] Furthermore, the super high-rise inward-tilting glass curtain wall ring track hoisting device also includes a power supply guide rail;

[0020] The power supply guide rail is fixed below the first cantilever arm or the second cantilever arm by a locking steel sleeve and bolts;

[0021] A control device and a T-shaped current collector shoe are provided at the center of the upper surface of the moving track.

[0022] The power supply rail is electrically connected to the control device and the T-shaped current collector shoe, and the power supply rail is electrically connected to the operation control platform, the rail trolley, and the cable.

[0023] Furthermore, a camera is provided at one end of the moving track, and a U-shaped protective steel sleeve is provided at one end of the moving track. The U-shaped protective steel sleeve is located outside the upper half of the camera, and a rubber gasket is provided between the U-shaped protective steel sleeve and the camera.

[0024] The camera is electrically connected to the operation control platform via a wire.

[0025] Furthermore, a hoisting part is provided at the end of the rope at the lower end of the electric hoist;

[0026] The hoisting unit includes a single-groove plate, which is rotatably connected to two first rods and two second rods within the single-groove plate via four hinged joints;

[0027] Both the first and second bars are border-shaped;

[0028] The first member can abut against the lower end of the curtain wall panel;

[0029] The second member can abut against the side end of the curtain wall panel.

[0030] Furthermore, one end of the second rod is connected to the movable block via a spring;

[0031] The movable block is rotatably connected to the single-slot plate via a hinge.

[0032] Two protective grooves are slidably provided on the movable block, and the two protective grooves are fixedly connected to the second rod.

[0035] The coupling connects the movable block or the first rod.

[0036] Furthermore, its construction method is as follows:

[0037] The first step is to move the glass curtain wall to a position parallel to the bottom of the single-groove plate, rotate the two second rods and the two first rods so that they respectively contact the side and bottom ends of the glass curtain wall, and drive the electric hoist to pull the glass curtain wall upward.

[0038] The second step is to move the electric hoist back and forth along the moving track to adjust the glass curtain wall.

[0039] The third step is to move the track trolley left and right along the circular track, so that the track trolley drives the moving track to move left and right, thereby allowing the glass curtain wall to move back and forth for adjustment.

[0040] The beneficial effects of this invention are as follows: It employs a movable track perpendicular to the two circular tracks below them. This movable track can move horizontally along the circular tracks via a track trolley. An electric hoist located on the movable track can move horizontally along the track perpendicular to the building surface. This solves the problem of glass curtain wall panels being unable to be installed when the installation location is too far from the building's inwardly inclined facade. It expands the applicability of the hoisting equipment, diversifies hoisting methods, and eliminates the need for manual traction, increasing construction safety. Furthermore, the electric hoist ensures uniform movement speed and force distribution of the curtain wall panels, reducing the likelihood of deflection or collision and enhancing stability.

[0052] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0053] Example 1

[0054] Please see Figure 1-2 As shown;

[0055] The ring-track hoisting device for inward-tilting glass curtain walls in ultra-high-rise buildings includes:

[0056] Support arm 1, which is installed on the floor slab and is used for load-bearing;

[0057] An annular track 2 is disposed below the support arm 1;

[0058] A track trolley 3 is slidably disposed at the bottom of the annular track 2;

[0059] The movable track 4 is fixedly connected to the track trolley 3 via double ear plates 5, and the movable track 4 and the circular track 2 intersect at different heights;

[0060] An electric hoist 6 is slidably mounted at the lower end of the moving track 4, and can move left and right along the moving track 4. Specifically, this invention employs a moving track 4 perpendicular to the two circular tracks 2 below them. The moving track 4 can move horizontally along the circular tracks 2 via a track trolley 3. The electric hoist 6, located on the moving track 4, can move horizontally perpendicular to the building surface along the moving track 4. This solves the problem of glass curtain wall panels being unable to be installed when the installation location is too far away from the inwardly inclined facade of the building. It expands the applicability of the hoisting equipment, makes the hoisting construction methods more diversified, and eliminates the need for manual traction, increasing construction safety. With the electric hoist 6, the curtain wall panels move at a uniform speed and bear uniform force, making them less prone to deflection and collision, thus enhancing stability.

[0061] Furthermore, the support arm 1 includes a first cantilever arm 11, which is provided with two sets of limiting steel plates 12 at the front and rear ends of the first cantilever arm 11. The two limiting steel plates 12 are used to block and limit the first cantilever arm 11. A first hanging ear plate 13 is provided on the first cantilever arm 11. A diagonal steel wire rope 14 is connected to one end of the first hanging ear plate 13. A second hanging ear plate 15 is provided at the other end of the diagonal steel wire rope 14.

[0062] The second hanging ear plate 15 is fixed to the upper floor slab with bolts;

[0063] The first cantilever arm 11 is provided with several locking steel sleeves 7 on its exterior. The locking steel sleeves 7 are fixed to the lower floor slab by bolts. Specifically, the structure of the arm part 1 is suitable for inter-floor tracks. The inclined steel wire rope 14 and the first hanging ear plate 13 and the second hanging ear plate 15 are used to ensure the firmness of the first cantilever arm 11. The inclined steel wire rope 14 is connected to the first hanging ear plate 13 and the second hanging ear plate 15 with steel wire rope buckles for easy disassembly and assembly. The length of the inclined steel wire rope 14 is adjusted with turnbuckles to ensure that all circular tracks 2 are at the same height.

[0064] Example 2

[0065] Please see Figure 3 As shown

[0066] The support arm 1 includes a second cantilever arm 101, a cross-shaped steel sleeve 102 disposed outside the second cantilever arm 101, a T-shaped steel sleeve 103 disposed outside the cantilever arm, a front steel column 104 vertically inserted through the cross-shaped steel sleeve 102, a rear steel column 105 vertically inserted through the T-shaped steel sleeve 103, a bottom steel plate 106 disposed at the lower end of the front steel column 104, and a diagonal steel tube 107 disposed between the front steel column 104 and the second cantilever arm 101.

[0067] The bottom steel plate 106 is fixedly connected to the roof floor slab by bolts;

[0068] The cross-shaped steel sleeve 102 is bolted to the front steel column 104, and the T-shaped steel sleeve 103 is bolted to the rear steel column 105. The T-shaped steel sleeve 103 and the cross-shaped steel sleeve 102 respectively increase the contact angle between the rear steel column 105 and the front steel column 104, making the fastening connection surface of the second cantilever arm 101 more comprehensive and less prone to collapse under load.

[0069] Furthermore, the support arm 1 also includes a fixed steel sleeve 1093 disposed at the lower end of the rear steel column 105, a support pad 109 disposed on one side of the fixed steel sleeve 1093, a concrete counterweight frame 1091 disposed at the upper end of the support pad 109, and a grouting steel pipe 1092 connected to the upper end of the concrete counterweight frame 1091. Grout can be injected into the concrete counterweight frame 1091 through the grouting steel pipe 1092 to flexibly increase the load-bearing capacity of the support pad 109, making the connection between the rear steel column 105 and the roof slab more secure and improving work efficiency. The support plate 109 is fixedly connected to the roof floor slab by bolts. Specifically, the structure of the support arm 1 is applicable to the roof track. The roof track uses a front steel column 104 and a rear steel column 105 to support the second cantilever arm 101. By setting a support structure on the second cantilever arm 101 to raise the height of the ring track 2, the maximum hoisting height of the ring track 2 covers the highest point of the curtain wall unit to be installed. This solves the problem that the conventional system of laying the ring track 2 at the edge of the roof floor slab cannot meet the hoisting construction problem of the highest glass curtain wall when the installation height of the curtain wall exceeds the height of the roof floor slab.

[0070] Example 3

[0071] Please see Figure 1-5 As shown

[0072] The super high-rise inward tilting glass curtain wall ring track hoisting device also includes a power supply guide rail 8;

[0073] The power supply guide rail 8 is fixed below the first cantilever arm 11 or the second cantilever arm 101 by a locking steel sleeve 7 and bolts;

[0074] A control device 9 and a T-shaped current collector shoe 10 are provided at the center of the upper surface of the moving track 4;

[0075] The power supply rail 8 is electrically connected to the control device 9 and the T-shaped current collector shoe 10, and the power supply rail 8 is electrically connected to the operation control platform, the track trolley 3, and the cable.

[0076] Furthermore, a camera 31 is provided at one end of the moving track 4, and a U-shaped protective steel sleeve 20 is provided at the other end of the moving track 4. The U-shaped protective steel sleeve 20 is located outside the upper half of the camera 31, and a rubber pad is provided between the U-shaped protective steel sleeve 20 and the camera 31. The U-shaped protective steel sleeve 20 can provide anti-collision effect for the camera 31, and the rubber pad can provide shock absorption during the impact process of the camera 31.

[0077] The camera 31 is electrically connected to the operation control platform via a wire. Specifically, the power supply rail 8 is set between two annular tracks 2 below the first cantilever arm 11 or the second cantilever arm 101, parallel to the two annular tracks 2, and is fixed to the first cantilever arm 11 or the second cantilever arm 101 by locking steel sleeves 7 and bolts. The control device 9 is mainly responsible for distributing the current and voltage required by the two track trolleys 3, the electric hoist 6, and the camera 31. It realizes the operation control of the device by connecting to the control operation platform. When the moving track 4 moves, the T-shaped current collector shoe 10 will move synchronously with it on the power supply rail, contacting the conductive block inside the power supply rail 8 to continuously obtain power input, without the need for edge following, thus solving the conventional annular track... When using track 2, the cable connecting the electric hoist 6 and the connection line of the control device 9 cannot move synchronously with the curtain wall ring track, which improves safety and convenience. This device adopts the method of adding a camera 31 at the end of the moving track 4 to make the entire hoisting process visible. Construction operators can lean out of the building to observe and determine the height and position of the glass curtain wall panels being lifted, which improves construction safety, installation accuracy of the glass curtain wall, construction efficiency of glass curtain wall panel hoisting, and saves labor costs. The two identical track trolleys 3 under the two ring tracks 2 are connected through the same signal control circuit to maintain synchronous movement, while the electric hoist 6 on the moving track 4 is controlled separately by another signal.

[0078] Example 4

[0079] Please see Figure 6-8 As shown,

[0080] The lower end of the electric hoist 6 is provided with a hoisting part 21 at the end of the rope;

[0081] The hoisting part 21 includes a single groove plate 211, which is a block with a groove at the lower end. Two first rods 212 and two second rods 213 are rotatably connected in the single groove plate 211 by four hinge parts 219.

[0082] Both the first member 212 and the second member 213 are in the shape of a border.

[0083] The first member 212 can abut against the lower end of the curtain wall panel;

[0084] The second rod 213 can abut against the side end of the curtain wall panel. Specifically, in the unused state, the two first rods 212 and the two second rods 213 can all maintain a free downward shape without any force. In the used state, the two first rods 212 can be rotated in opposite directions through the hinge 219 to maintain a vertical tilt angle, and the two second rods 213 can be rotated in opposite directions through the hinge 219 to a horizontal angle. The two first rods 212 and the two second rods 213 form a six-shaped structure with the rope, so that when the glass curtain wall panel is inserted, its lower and side parts are abutted and limited to prevent it from falling off, ensuring the safety of the hoisting work and preventing the glass curtain wall panel from falling due to insecure mounting or uneven force angle.

[0085] Furthermore, one end of the second rod 213 is connected to the movable block 215 via a spring 214;

[0086] The movable block 215 is rotatably connected to the single-slot plate 211 via the hinge part 219;

[0087] Two protective groove plates 216 are slidably provided on the movable block 215. The two protective groove plates 216 are fixedly connected to the second rod 213. The protective groove plates 216 are plate-shaped with grooves at the bottom, ensuring that when they are slidably connected to the movable block 215, they can only slide back and forth.

[0088] A connecting rod 218 that can sideways abut against the movable block 215 is connected between the two sets of protective groove plates 216. Specifically, during the hoisting of the glass curtain wall, the second rod 213 can stretch the spring 214, so that the second rod 213 can sideways fit against the wider glass curtain wall panel to ensure the suitability of the glass curtain wall panel during hoisting. The two protective groove plates 216 can slide left and right with the second rod 213 to ensure the accuracy of the elastic trajectory of the spring 214. When the glass curtain wall panel tilts to the side, the glass curtain wall panel can abut against the second rod 213 and pull the protective groove plate 216, so that the protective groove plate 216 pulls the connecting rod 218 to abut against the movable block 215, so that the tilting action of the glass curtain wall panel is blocked, and the impact force during the process is dissipated by the elastic work of the spring 214.

[0089] Furthermore, the hinge portion 219 includes a bushing 2191 connecting the single groove plate 211, a rubber sleeve 2192 glued to the bushing 2191, and a connecting shaft 2193 rotatably connected to the bushing 2191 with an interference fit.

[0090] The connecting shaft 2193 connects to the movable block 215 or the first rod 212. Specifically, the rubber sleeve 2192 is flexible and elastic, allowing the connecting shaft 2193 to rotate with resistance. After the connecting shaft 2193 can rotate, it can maintain the rotation angle, which is conducive to the real-time angle adjustment of the first rod 212 and the second rod 213, making it more convenient for the first rod 212 and the second rod 213 to fit the glass curtain wall panels at different angles.

[0091] Working principle: During the installation of glass curtain wall panels, a large number of glass curtain wall installation components and materials need to be hoisted. The inter-floor tracks and accessories are transported to the floor to be installed via a construction elevator, and the roof tracks and accessories can be transported to the roof using a construction tower crane. All materials are neatly stacked according to the type of accessories and installation position, and then assembled by professional operators. Before assembly, the operators need to use a total station to lay out and position the first cantilever arm 11 and the second cantilever arm 101 and the upper hanging parts of the two-division layout of the circular track. Only after checking that everything is correct can the installation work be carried out to complete the track positioning and layout.

[0092] The installation and fixing measures for the horizontal ring rail support system are as follows:

[0093] The front end of the first cantilever arm 11 is limited by expansion bolts and square washers. The top is welded with a first hanging ear plate 13 for connecting with the inclined steel wire rope 14. The rear end of the first cantilever arm 11 can be connected to the pre-embedded parts of the structural edge by bolts. The left and right division and front and back positions of the first cantilever arm 11 are adjusted and fixed.

[0094] The installation measures for the inclined steel wire rope 14 and its fixing points are as follows:

[0095] Inter-floor track: The inter-floor track can be constructed by using a diagonal steel wire rope 14 to diagonally support the first cantilever arm 11. One end of the diagonal steel wire rope 14 is fixed to the second hanging ear plate 15 at the top edge of the floor slab of the floor above the track installation floor, and the other end is fixed to the first hanging ear plate 13 at the top front end of the first cantilever arm 11. The connection between the diagonal steel wire rope 14 and the hanging ear plate is secured with a diagonal steel wire rope 14 clip for easy assembly and disassembly. Turnbuckles are used to adjust the length of the steel wire rope at the connection between the diagonal steel wire rope 14 and the first cantilever arm 11 to ensure that all tracks are at the same height.

[0096] Roof track: The roof track is supported by a front steel column 104 and a rear steel column 105 for the second cantilever arm 101. One end of the front steel column 104 and the rear steel column 105 is connected and fixed to the embedded parts of the main roof floor slab by high-strength bolts, and the other end is welded to the bottom of the second cantilever arm 101. The connection is reinforced and fixed by T-shaped steel sleeves 103 and cross-shaped steel sleeves 102 and limit bolts. The front steel column 104 and the second cantilever arm 101 are connected to each other by a diagonal steel tube 107 to improve stability.

[0097] The installation procedure for the horizontal circular track beam is as follows: First, fix the scaffold boards on the first cantilever arm 11 and the second cantilever arm 101. Use the hand-operated hoist temporarily fixed on the upper layer to lift the circular track 2 and slide it to the installation position at the front end of the first cantilever arm 11 and the second cantilever arm 101. Insert the moving track 4 into the slot of the fixed U-steel sleeve 108, and then slide the other end into the slot of another first cantilever arm 11 or second cantilever arm 101. After adjusting and positioning, tighten the limiting bolt. Install other moving tracks 4 in this way. Finally, fix two adjacent moving tracks 4 in series with bolts, spot weld them, and then grind them.

[0098] The entire hoisting device is powered by electricity, which is supplied through cables and power supply rails 8. Power supply rails 8 are located between the two circular tracks 2 of the first cantilever arm 11 and the second cantilever arm 101. A control device 9 and a T-shaped current collector shoe 10 are located in the middle above the moving track 4. During the movement of the track trolley 3, the T-shaped current collector shoe 10 on the moving track 4 can continuously supply power by following the movement of the power supply rail 8 and always maintaining contact with the power supply line inside the power supply rail 8. The inner wall of the power supply rail 8 is provided with an insulating layer to prevent electric shock and leakage.

[0099] The glass curtain wall panels are connected to the electric hoist 6 on the moving track 4 via the hoisting unit 21, enabling vertical movement of the materials. After the glass curtain wall panels are lifted to the installation floor height, the two identical track trolleys 3 under the two circular tracks 2 are controlled to move horizontally along the circular tracks 2 to the floor to be installed. Then, the electric hoist on the moving track 4 is controlled to move the 6 curtain wall unit panels horizontally from the far end of the floor to the precise installation position near the edge of the floor. After the panels are in place, the construction personnel need to insert, position, and adjust them until the installation is completed.

[0100] During the hoisting process, guy ropes are installed at both ends of the glass curtain wall panel hoisting device to prevent overturning caused by wind or other factors during transportation and to increase stability. The operators responsible for the hoisting device must ensure that the curtain wall glass components or materials are securely fixed before they can start the hoisting device to carry out the component hoisting work.

[0101] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
