Technical Field
[0001] This invention belongs to the field of building curtain wall construction technology, and specifically relates to an installation device and method for prefabricated glass curtain walls. Background Technology
[0002] Building curtain walls are an important component of building facades, serving multiple functions such as decoration, lighting, ventilation, thermal insulation, and sound insulation. They are widely used in various mid- to high-rise buildings, including commercial complexes, office buildings, and convention centers. Among them, prefabricated glass curtain walls, which are assembled into complete curtain wall structure units by processing various curtain wall panels, structural frames, and components in a factory, and then installed on the main structure as an outer curtain wall through a transfer method, have become the mainstream choice for the facade design of high-rise buildings.
[0003] However, existing technologies for installing prefabricated curtain walls suffer from low construction efficiency, high safety risks, and difficulties in controlling installation accuracy. They are particularly ill-suited to the comprehensive requirements of high-rise and super high-rise buildings for construction quality, efficiency, and safety. Specifically, firstly, traditional operations rely on suspended platforms or scaffolding, requiring individual glass curtain wall units to be positioned, fixed, and sealed on-site sequentially. This process is cumbersome, with an average installation time exceeding 30 minutes per unit, and is significantly affected by adverse weather conditions such as wind and rain, making it difficult to guarantee project progress. Secondly, prolonged work at height increases the risk of glass tipping or falling during handling and installation. Furthermore, the cumulative errors from on-site measurements and manual assembly often result in an overall flatness deviation of the curtain wall exceeding 5mm, failing to meet design requirements for flatness deviation. Summary of the Invention

[0006] Furthermore, the prefabricated glass curtain wall unit includes the curtain wall frame, the curtain wall glass, and the curtain wall positioning pins; The curtain wall frame is a rectangular frame structure, and the curtain wall glass is fixed at the bottom of the curtain wall frame; the curtain wall positioning pins are arranged at the four corners of the curtain wall frame to position and fix the curtain wall frame to the building body.
[0007] Furthermore, it also includes a laser emitter, a laser positioning component, and a central controller; The laser emitter is set on a preset reference point of the installed prefabricated glass curtain wall unit or the main building body, and the laser emitter is used to emit a preset reference laser surface; The laser positioning components are located on the outer sides of both ends of the adjustable gripper mounting box. The laser positioning components are used to receive and send a reference laser surface to the central controller. The central controller is installed inside the connection box. The central controller is used to generate and send a gripper adjustment command to the adjusting gripper assembly based on the received reference laser surface. The gripper adjustment command is used to drive the adjusting gripper assembly to slide at the bottom of the adjusting gripper mounting box.
[0008] Furthermore, it also includes suction cup fixing components and binding straps; The suction cup fixing assembly is disposed on the upper part of the inner surface of the curtain wall glass. The upper end of the suction cup fixing assembly is connected to the fixing base installed on the inner side of the bottom end of the curtain wall frame, and the lower end of the suction cup fixing assembly is connected to one end of the binding strap. The suction cup fixing assembly can be adsorbed and fixed to the inner surface of the curtain wall glass by vacuum adsorption. The other end of the binding strap goes around the bottom of the curtain wall glass and passes through the outer surface of the curtain wall glass before connecting to the curtain wall frame.
[0009] Furthermore, the suction cup fixing assembly includes a vacuum suction cup, a vacuum pump, a strap switch, and a signal receiver; The vacuum suction cup is adsorbed and fixed to the upper inner surface of the curtain wall glass, and the top of the vacuum suction cup is connected to the fixing base; the vacuum pump is set on the top side of the vacuum suction cup, and the vacuum pump is used to perform vacuum treatment on the vacuum suction cup. One end of the strap switch is connected to the bottom side of the vacuum suction cup, and the other end of the strap switch is connected to the end of the strap. The output terminal of the signal receiver is connected to the vacuum pump control terminal, and the input terminal of the signal receiver is connected to the central controller; wherein, the central controller is further configured to generate a vacuum pump operating command and a switching command based on the received reference laser surface; wherein, the vacuum pump operating command is used to trigger the vacuum pump to turn on or off; and the switching command is used to trigger the strap switch to turn on.
[0010] Furthermore, the laser positioning assembly includes a telescopic arm, a receiver mounting block, and a laser receiver; The telescopic arm is horizontally installed on both sides of the adjusting gripper mounting box and can extend and retract horizontally in the direction away from or towards the adjusting gripper mounting box; the receiver mounting block is a cubic structure, one face of the receiver mounting block is connected to the free end of the telescopic arm, and a laser receiver is respectively provided on the remaining face of the receiver mounting block; wherein, each laser receiver is used to receive and send a reference laser surface to the central controller.
[0011] Furthermore, the adjustable grab arm mounting box is a hollow box structure with an open bottom. The interior of the adjustable grab arm mounting box is provided with a grab arm slide rail, and the top of the adjustable grab arm assembly is slidably mounted on the grab arm slide rail. The axial direction of the grab arm slide rail is perpendicular to the exterior facade of the building.
[0012] Furthermore, the adjustable grab arm assembly includes a traveling mechanism, an upper swing arm, a connecting shaft, a lower swing arm, and a curtain wall fastener; The traveling mechanism is slidably mounted on the grab arm slide rail. The top end of the upper swing arm is connected to the bottom end of the traveling mechanism. The bottom end of the upper swing arm is connected to the top end of the lower swing arm through the connecting shaft. The bottom end of the lower swing arm is connected to the top end of the curtain wall frame through the curtain wall fastener.
[0013] Furthermore, the control terminal of the walking mechanism is connected to the central controller; wherein, the central controller is also used to generate and send a walking adjustment command to the walking mechanism based on the received reference laser surface; wherein, the walking adjustment command is used to trigger the walking mechanism to slide along the grab arm slide rail.
[0014] The present invention also provides an installation method for prefabricated glass curtain walls, utilizing the aforementioned installation device for prefabricated glass curtain walls; Installation methods include: The precast glass curtain wall unit is fixed to the bottom of the adjusting grab arm assembly; then, the hoisting rope is connected to the preset hoisting equipment, and the hoisting of the precast glass curtain wall unit begins; when the precast glass curtain wall unit is hoisted to the preset installation position, the top of the adjusting grab arm assembly slides at the bottom of the adjusting grab arm mounting box to adjust the position of the precast glass curtain wall unit until the precast glass curtain wall unit reaches the preset installation accuracy, and then the positioning, fixing and sealing of the precast glass curtain wall unit begins.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The installation device for prefabricated glass curtain walls provided by this invention, through the coordinated operation of hoisting ropes, connecting boxes, connecting pipes, adjusting grab arm mounting boxes, and adjusting grab arm assemblies, achieves overall hoisting by connecting the hoisting ropes to pre-set hoisting equipment. This eliminates the safety hazards of workers handling at heights and glass tipping or falling during installation, significantly reducing safety risks. Specifically, the top of the adjusting grab arm assembly is slidably connected to the bottom of the adjusting grab arm mounting box. After the curtain wall unit is hoisted to the installation area, the position of the prefabricated glass curtain wall unit can be finely adjusted by sliding the adjusting grab arm assembly at the bottom of the mounting box. This effectively compensates for the accumulated errors of traditional on-site measurement and manual assembly, controlling the overall flatness deviation of the curtain wall within the design requirements, significantly improving installation accuracy and efficiency, and better meeting the comprehensive requirements of high-rise and super high-rise buildings for construction quality, efficiency, and safety.
[0016] Furthermore, designing the curtain wall frame as a rectangular frame structure provides a stable mounting platform for the curtain wall glass, ensuring its secure fixing and preventing damage due to uneven stress during hoisting and installation. Simultaneously, positioning pins are placed at the four corners of the curtain wall frame. The precision of corner positioning allows for rapid positioning and guidance when the prefabricated glass curtain wall units are connected to the building structure, reducing on-site positioning errors and effectively improving installation accuracy. This also simplifies subsequent fixing procedures and, combined with the overall hoisting structure, significantly shortens installation time, balancing stability and efficiency.
[0017] Furthermore, a reference laser surface is emitted from the laser emitter at the reference point of the installed curtain wall unit or the main building, providing a precise visual reference for installation positioning. The laser positioning component receives the reference laser surface in real time and feeds it back to the central controller. The central controller automatically generates a grab arm adjustment command based on the feedback signal, driving the adjustment grab arm component to slide and achieve fine adjustment of the curtain wall unit position. This realizes automated control of the installation and positioning of prefabricated glass curtain wall units, eliminating the need for manual adjustment by workers at height. This reduces the safety risks of workers working at height and significantly improves the accuracy and efficiency of position adjustment, making it suitable for the stringent installation accuracy requirements of high-rise and super high-rise buildings.
[0018] Furthermore, the suction cup fixing assembly uses vacuum adsorption to fix the glass to the upper part of the inner surface of the curtain wall glass, which can not only achieve a quick connection between the curtain wall glass and the device, but also avoid damage to the surface of the curtain wall glass. At the same time, one end of the binding strap is connected to the suction cup fixing assembly, and the other end goes around the bottom of the curtain wall glass and connects to the curtain wall frame, forming a two-way fixing structure for the curtain wall glass. This limits the position of the curtain wall glass from both the top and bottom, effectively preventing the curtain wall glass from tipping over or slipping during hoisting and position adjustment. This effectively improves work efficiency while enhancing the stability of the curtain wall unit during hoisting.
[0019] Furthermore, by setting up a grab arm slide rail, a stable guiding structure is provided for adjusting the sliding of the grab arm assembly, ensuring the smoothness of the sliding process of the grab arm assembly, avoiding positional deviation of the curtain wall unit caused by sliding offset, and improving adjustment accuracy. Among them, the design of the grab arm slide rail axis being perpendicular to the exterior facade of the building body makes the sliding direction of the adjusting grab arm assembly consistent with the installation and fitting direction of the curtain wall unit, which can directly realize the fitting degree adjustment between the curtain wall unit and the exterior facade of the building body, simplifying the adjustment process and improving adjustment efficiency.

[0043] Installation method and working principle: Based on the above-described installation device for prefabricated glass curtain walls, this embodiment also provides an installation method for prefabricated glass curtain walls, including: The precast glass curtain wall unit is fixed to the bottom end of the adjusting grab arm assembly 5; then, the hoisting rope 1 is connected to the preset hoisting equipment to start the hoisting of the precast glass curtain wall unit; when the precast glass curtain wall unit is hoisted to the preset installation position, the top end of the adjusting grab arm assembly 5 slides at the bottom end of the adjusting grab arm mounting box 4 to adjust the position of the precast glass curtain wall unit until the precast glass curtain wall unit reaches the preset installation accuracy, and then the positioning, fixing and sealing of the precast glass curtain wall unit begins.
[0044] Specifically, the installation method for prefabricated glass curtain walls includes the following steps: Step 1, Preliminary Preparation: Complete the prefabrication, testing, and information labeling of all prefabricated glass curtain wall units in the factory; during the construction of the main building, pre-embed the fixing bases to ensure that the pre-embedding deviation of the fixing bases is less than or equal to 3mm.
[0045] Step 2, Transportation and Lifting: Place the precast glass curtain wall unit on a transport frame with flexible cushioning pads and transport it to the construction site. Before lifting, use four binding straps 8 and four suction cup fixing components 7 to bind the curtain wall glass 200 in the precast glass curtain wall unit. Start the vacuum pump 73 to ensure that the vacuum suction cups 71 are properly adsorbed on the surface of the curtain wall glass 200. Then, fix the curtain wall fixing device 55 in the adjusting grab arm assembly 5 to the curtain wall frame 100 in the precast glass curtain wall unit. Next, use a tower crane to lift the precast glass curtain wall unit to the preset installation area. During the tower crane lifting process, use traction ropes to help control the air posture of the precast glass curtain wall unit to avoid rotation and swaying, until the precast glass curtain wall is transported to the outside of the target installation floor.
[0046] Step 3: Positioning, Fine-tuning, and Mechanical Locking: After the prefabricated glass curtain wall unit reaches the preset installation area, the laser emitter and laser positioning component 6 are turned on to monitor the real-time position of the prefabricated glass curtain wall unit. Using the central controller, the walking mechanism 51 is controlled according to the received base laser surface to achieve fine-tuning of the position of the prefabricated glass curtain wall unit until the installation position deviation of the prefabricated glass curtain wall unit is within the allowable range. Then, the prefabricated glass curtain wall unit is positioned and fixed using the curtain wall positioning pin 300. Afterward, the fixed base 400 and the fixed base are locked and fixed.
[0047] Step 4: Release Adsorption, Sealing, and Stage Inspection: After positioning and locking using the curtain wall positioning pins 300 and fixing bases 400, the central controller controls the vacuum pump 73 to shut down, releasing the adsorption force of the curtain wall glass; then, the central controller controls the binding strap switch 74 to open; the suction cup fixing assembly 7 is retrieved, completing the installation of the precast glass curtain wall unit; subsequently, silicone weather-resistant sealant is injected at the joints of adjacent precast curtain wall glass to strengthen the seal; after the installation of every 10 precast glass curtain wall units is completed, a sampling pressure spray water test is conducted to test water tightness, and a total station is used to scan the flatness to ensure that the cumulative deviation meets the design requirement of less than or equal to 3mm.
[0048] Step 5: Post-replacement maintenance and replacement. When a single precast glass curtain wall unit needs to be replaced, simply remove the sealant around the unit to be replaced, pull out the curtain wall positioning pin 24, and disconnect the connection between the fixing base and the fixing seat. Then, the unit to be replaced can be removed using hoisting equipment. Install and seal the pre-installed new unit according to steps 3 and 4.
[0049] The installation system for prefabricated glass curtain walls described in this embodiment achieves overall hoisting by coordinating hoisting ropes, connecting boxes, connecting pipes, adjustable grab arm installation boxes, and adjustable grab arm assemblies, connecting the hoisting ropes to pre-set hoisting equipment. This not only achieves a multiple increase in construction efficiency and a significant reduction in construction period, but also greatly reduces the risks of high-altitude operations through a fundamental change in the work process, ensuring sealing quality and installation accuracy from the source, and enabling the curtain wall performance to stably meet or even exceed the current highest standard requirements. In this embodiment, through the combination of highly integrated modular design and factory prefabrication, the core drawbacks of traditional on-site installation methods are systematically solved, significantly reducing the overall cost throughout the entire life cycle, and providing a complete, efficient, safe, economical, and reliable solution for curtain wall projects of high-rise and super high-rise buildings.
[0050] In this embodiment, a laser emitter positioned at a reference point on the installed curtain wall unit or floor slab emits horizontal and vertical reference laser surfaces; the laser receiver 63 converts the received light signal into an electrical signal and transmits it to the central controller; the central controller controls the walking mechanism 51 to move on the grab arm slide rail, thereby driving the entire adjusting grab arm assembly 5 to swing, thus causing the prefabricated glass curtain wall unit to make fine-tuned angle adjustments in a plane parallel to the building facade; a suction cup fixing assembly 7 and a binding strap 8 are used to safely attach the glass panel 1 and assist in hoisting; wherein, the suction cup fixing assembly... The vacuum suction cup 71 in 7 is connected to the vacuum pump 73 through a pipeline, and the vacuum pump 73 is connected to the central controller through the signal receiver 72. Before hoisting, the vacuum pump 73 is started by the central controller to generate negative pressure in the vacuum suction cup 71, which firmly adsorbs the curtain wall glass 200. The curtain wall glass 200 is then tied and fixed with the binding strap 8. When the prefabricated glass curtain wall unit reaches the preset installation position, the vacuum pump 73 and the binding strap switch 74 in the suction cup fixing assembly 7 receive the information command from the central controller, start the binding strap switch 74, and turn off the vacuum pump 73.
[0051] The installation device for prefabricated glass curtain walls described in this invention effectively solves the technical problems of low construction efficiency, high risk of high-altitude operations, difficulty in controlling installation accuracy, and inconvenience of later maintenance in traditional curtain wall construction through highly integrated modular prefabrication and intelligent on-site installation. It significantly improves construction quality, safety, and overall economic benefits, and is especially suitable for curtain wall projects of high-rise and super high-rise buildings.
[0052] The above embodiments are merely one of the implementation methods for achieving the technical solution of the present invention. The scope of protection claimed by the present invention is not limited to this embodiment, but also includes any variations, substitutions and other implementation methods that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention.
