Description

Technical Field

[0001] This invention relates to the field of curtain wall assembly technology, and in particular to a curtain wall track hoisting and positioning device based on a BIM system and its usage method. Background Technology

[0002] In modern architecture, curtain walls, especially glass curtain walls, have become an indispensable and important component of public buildings, particularly high-rise buildings, serving as a crucial medium for showcasing architectural facades and visual effects. Compared to traditional solid brick walls, glass curtain walls offer advantages such as lighter weight, greater transparency, and better lighting, providing excellent interior views. As people's living standards continue to improve, their pursuit of a higher quality of life is also increasing, leading to the emergence of many aesthetically pleasing buildings in cities. However, these buildings often feature avant-garde designs and frequently utilize irregularly shaped curtain walls. While most curtain walls on the market are rectangular or triangular panel structures, which are relatively easy to install, these more artistically oriented buildings often employ curved shell structures. This makes it difficult to secure and install them using only ropes, and the corners are more susceptible to damage and deformation due to the overall pressure during installation.

[0003] For example, Chinese patent application numbers CN202111675305 and 9 disclose a hoisting device and hoisting control method for curtain wall glass. The device includes: a vehicle body, a component fixing bracket, a lifting component, a panoramic lens, a gripping component, and a detection lens. The component fixing bracket is disposed on the top surface of the vehicle body, the lifting component is disposed on the component fixing bracket, the panoramic lens is disposed on the top of the component fixing bracket, the gripping component is connected to the lifting component and moves up and down with the lifting component, and the detection lens is disposed on the gripping component.

[0004] The above solution can achieve automatic identification, grabbing, hoisting and transmission of the curtain wall through various lenses, lifting components, grabbing components and vehicle body, reducing the workload of installation, reducing the difficulty of installation, shortening the assembly time and human resource costs. However, the complex structure of the device still makes it unable to adapt to the shape of curved glass for efficient and accurate installation, and requires the construction of additional transportation and lifting devices, which increases the assembly cost. Summary of the Invention

[0005] In view of the problems mentioned in the background art regarding the complex structure, limited application, and high construction and maintenance costs of existing curtain wall hoisting devices, this invention provides a curtain wall track hoisting and positioning device based on a BIM system. The device uses a support guide rail mechanism to support a multi-functional mechanical mechanism to mark the positions of the curtain wall panels to be installed, and combines BIM technology to construct a building information model to ensure that the subsequent glass hoisting work is completed efficiently and accurately.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A curtain wall track hoisting and positioning device based on a BIM system includes:

[0008] Support rail mechanism, a hoisting support mechanism installed on the top of a building;

[0009] A multi-functional mechanical mechanism is slidably mounted on a support guide rail mechanism to complete the hoisting of curtain wall panels;

[0010] The displacement drive mechanism drives the multi-functional mechanical mechanism to move along the support guide rail mechanism.

[0011] The multi-functional mechanical mechanism is connected to the BIM system, and the multi-functional mechanical mechanism performs point measurements on the position of the panel to be installed before hoisting the curtain wall panel.

[0012] This application utilizes BIM technology for model creation, simulation testing, and point calibration. The main and secondary keels and track hoisting devices are then installed according to the calibrated points. The track hoisting device disclosed in this application can be controlled by a motor to move a multi-functional mechanical device, using guide rails and steel cables as auxiliary mechanisms, to a designated position in a plane. This multi-functional mechanical device can perform point calibration, precise distance measurement, and remote sensing transmission. It can also hoist and clamp curved glass curtain walls. The entire process is simulated in real-time using BIM technology, with feedback and follow-up. This application employs a multi-functional mechanical mechanism for the hoisting of curtain wall panels and the measurement work before hoisting. By deploying a supporting guide rail mechanism on the top of the building, it ensures that the multi-functional mechanical mechanism can accurately move and transport the curtain wall panels within a preset range.

[0013] Furthermore, the supporting guide rail mechanism includes a base platform disposed on the top of the building and an extended guide rail extending outward from the top of the building. The displacement driving mechanism includes a first moving motor disposed on the extended guide rail, and the multifunctional mechanical mechanism is disposed on the first moving motor. The machine platform is used to provide counterweight for the extended guide rail, ensuring that the displacement driving mechanism remains stable during the operation of the multifunctional mechanical mechanism. The extended guide rail extends outward from the top edge of the building facade. The first moving motor can drive the multifunctional mechanical mechanism to move in the near and far directions on the facade. Since the facade has various structural forms, the forward and backward movement of the multifunctional mechanical mechanism can ensure the smooth completion of point marking and hoisting work.

[0014] Preferably, the supporting guide rail mechanism includes a supporting column mounted on the top of the building; a winch assembly is mounted on the base, the winch assembly including connecting cables connected to both ends of the extended guide rail, and the winch assembly drives the extended guide rail to move up and down along the supporting column. The winch assembly is used to control the overall height and angle of the extended guide rail; when the building facade is an inclined or curved structure, the winch assembly adapts to the building facade structure by controlling the height of both ends of the extended guide rail and tilting the angle of the multi-functional mechanical mechanism, ensuring more accurate and reasonable point measurement and hoisting positions.

[0015] Preferably, the multifunctional support mechanism includes a drive module with a base on the drive module, a rotating track on the base, and a pair of distance measuring sliders on the rotating track. Several lifting rods are arranged along the edge of the drive module, and suction cups are attached to the top of each lifting rod. The distance measuring sliders can move inward and outward along the radius of the base, making them more flexible in use. They can reduce their occupied space before reaching the desired position to avoid interference with other objects, and when ready to measure, they can expand outward to obtain a sufficient measurement range, resulting in excellent practical performance.

[0016] Preferably, the distance measuring slider is slidably mounted on a rotating track. The distance measuring slider includes a wireless transmission module and a laser distance measuring module. A drive motor is also mounted on the distance measuring slider, and a drive belt connects the drive motor and the distance measuring slider. The distance measuring slider is driven by the drive motor to rotate the drive belt, thus reciprocating on the rotating track to adjust the coverage area. The rotating track can rotate 360 ​​degrees on the base, allowing the line connecting the two distance measuring sliders to cover the entire plane, effectively increasing the distance measuring range of the slider. This allows for flexible and convenient access to target locations using the laser distance measuring module when facing various structural facades. It can also measure flatness through scanning. Combining the laser distance measuring module with a BIM system can improve the accuracy of the building information model. The distance measuring slider has its own remote sensing and transmission device, which can remotely sense and measure distance and curvature, transmit real-time data, check the accuracy of point calibration, determine the curvature of the wall, and interface with the BIM system in real time.

[0017] Preferably, the base includes a wireless transmission ring, on which a fastener disc is fixedly mounted. A track fastener is fastened to the fastener disc, and the rotating track is welded to the track fastener. The drive module includes a brake motor, which includes a rotating central shaft that passes through the base and is fixedly connected to the track fastener. The wireless transmission ring includes a horizontal sensing instrument and a wireless transmission instrument, capable of sensing the current angular position of the ranging rotating track. The track fastener transmits the power provided by the brake motor from the rotating central shaft to the rotating track, ensuring that the rotating track can carry the ranging slider for accurate measurement.

[0018] Preferably, each of the four corners of the drive module is equipped with a lifting motor, and the lifting rod is connected to the lifting motor. Except when the multi-functional mechanical mechanism is not performing glass adsorption, the lifting motor keeps the lifting rod within the drive module to avoid positional interference. When it is necessary to hoist the curtain wall panel, the lifting motor drives the lifting rod to extend. Operators can install suction cups at the ends of the lifting rods. The specifications of the suction cups can be selected according to the size and shape of the curtain wall panel. After installation, it is ensured that the curtain wall panel is stably connected to the suction cups of each lifting rod, ensuring safe and stable hoisting operations.

[0019] Preferably, the supporting guide rail mechanism is further provided with a transverse guide rail arranged along the width direction of the facade. The displacement driving mechanism includes a second moving motor mounted on the transverse guide rail, which drives the base and support column to move along the transverse guide rail. The transverse guide rail is arranged along the width direction of the facade, allowing the extended guide rail to move within a certain range in the width direction. Obviously, the shape of the transverse guide rail corresponds to the shape of the building facade, including but not limited to straight lines, arcs, and V-shapes. This multi-functional mechanical mechanism, capable of moving in close contact with the facade surface, can more flexibly assist in the installation of curtain wall panels. Especially for small-sized curtain wall panels, it avoids increasing the workload of operators due to misalignment in the width direction, eliminating the need for additional pulling devices to readjust the position of the curtain wall panels, and ensuring that each curtain wall panel is correctly aligned in its installation position.

[0020] This invention also discloses a method for using the above-mentioned curtain wall track hoisting and positioning device based on a BIM system, including the following steps:

[0021] S1: Construct a building model of the curtain wall panels to be installed using a BIM system, and conduct collision tests and simulation experiments;

[0022] S2: Mark the anchor points of the track hoisting device according to the shape of the building facade, and install the support guide rail mechanism according to the anchor points;

[0023] S3: Install the multi-functional mechanical mechanism and displacement drive mechanism on the support guide rail mechanism, and ensure that the multi-functional mechanical mechanism is connected to the BIM system during installation;

[0024] S4: Construction begins. A pair of distance measuring sliders slide to the closest distance, and the winch assembly lowers the outer guide rail so that the multi-functional mechanical mechanism reaches the position where the curtain wall panel is to be installed.

[0025] S5: The drive module controls the rotating track to rotate and stop at each preset angle, and drives the distance measuring slider to measure the building information parameters at each preset angle through the transmission motor;

[0026] S6: The winch assembly lowers the multi-functional mechanical mechanism to the position where the glass to be hoisted is placed, the drive module drives the lifting rod to attract the glass to be hoisted, and the winch assembly lifts the multi-functional mechanical mechanism to the top;

[0027] S7: A pair of distance measuring sliders slide to their farthest distance, the winch assembly lowers the multi-functional mechanical mechanism to the curtain wall panel installation position, the distance measuring sliders move closer to each other and to the keel of the curtain wall panel installation position, the lifting rod drives the curtain wall panel to move closer to the curtain wall panel installation position, and the installation is completed manually.

[0028] Before using the BIM-based curtain wall track hoisting and positioning device, a model should be built using BIM technology, and collision and simulation tests should be conducted to mark the anchoring points of the track hoisting device. Anchor the panels at the anchoring points and install the track hoisting device, ensuring it is perpendicular to the wall surface. After installing the track positioning and hoisting device, it can be used in various construction processes such as surveying and setting out, checking the position of embedded T-slots, locating the support brackets, and adjusting the straightness of the curtain wall, or in environments requiring point marking, precise distance measurement, flatness testing, and positioning and setting out. During use, first tighten the distance measuring slider, then lower the multi-functional mechanical device to the designated position using a winch. Next, remotely rotate the track to the designated position and open the distance measuring slider outwards, waiting for the distance measuring slider to transmit the distance data. Repeat the process of remotely rotating the track and opening the distance measuring slider until all distance measurement steps are completed. During hoisting and installation, two winches are used to quickly lower the multi-functional mechanical device. Then, based on BIM simulation calculations and the floor surface location data and curvature, a telescopic suction cup extends to a specified length to lift the glass curtain wall panel to be installed. It is then quickly raised to the top, and the distance measuring slider is extended to its maximum distance. The horizontal motor is then remotely controlled to move to the designated point for lowering. First, the steel cables of both winches are lowered. Upon reaching the designated point, one winch is fixed while the other is lowered until the installation point is reached, thus satisfying the "fast first, slow later" lowering method to ensure safety and efficiency. After reaching the designated potential, the distance measuring slider is retracted to the clamping position on the keel, the suction cup on the lifting rod extends, and finally, the curtain wall panel is installed.

[0029] It is worth noting that during construction, the BIM system should be connected and simulated in real time. The multi-functional mechanical device in the initial state is mainly used for multiple steps in the construction process, such as measurement and layout, checking the position of the embedded T-slots, locating the support and adjusting the straightness of the curtain wall. Its main functions are flatness detection, distance detection and quality control.

[0030] Furthermore, a transverse guide rail is installed on the top of the facade, and several extended guide rails can be installed on the transverse guide rail, each of which is equipped with a multi-functional mechanical mechanism.

[0031] Once the transverse guide rails are installed on the exterior of the building, multiple sets of extended guide rails can be installed on the transverse guide rails, enabling multiple sets of multi-functional mechanical mechanisms to work simultaneously, significantly improving the efficiency of curtain wall construction.

[0032] Therefore, the present invention has the following beneficial effects:

[0033] 1) By supporting the guide rail mechanism, the multi-functional mechanical mechanism marks the location of the curtain wall panel to be installed, and combines BIM technology to build a building information model to ensure that the subsequent glass hoisting work is completed efficiently and accurately;

[0034] 2) Since the facade has various structures, the multi-functional mechanical mechanism that moves back and forth can ensure the smooth completion of point marking and hoisting work by cooperating with the support guide rail mechanism and the displacement drive mechanism.

[0035] 3) A pair of distance measuring modules can be used together and rotated, split and joined to accurately measure various structural parameters of the curtain wall panel to be installed. Combined with the BIM system, the position correction is completed during the hoisting of the multi-functional mechanical mechanism, ensuring that the curtain wall panel is accurately placed at the target position when hoisting, and shortening the time for operators to prepare before installation.

[0036] 4) The two winches of the winch assembly work together to adjust the height of the multi-functional mechanical mechanism and the tilt angle of the multi-functional mechanical mechanism and the curtain wall panel, so that it is more in line with the setting angle of the facade keel before installation, thereby improving the assembly efficiency of irregular curtain walls.

[0049] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0050] Example 1

[0051] A curtain wall track hoisting and positioning device based on a BIM system includes: a support guide rail mechanism and a hoisting support mechanism installed on the top of the building; a multi-functional mechanical mechanism 1, which is slidably installed on the support guide rail mechanism 2 to complete the hoisting of the curtain wall panel 100; a displacement driving mechanism that drives the multi-functional mechanical mechanism to move along the support guide rail mechanism; the multi-functional mechanical mechanism is connected to the BIM system, and the multi-functional mechanical mechanism performs point measurement on the position of the panel to be installed before hoisting the curtain wall panel.

[0052] The application utilizes BIM technology for model creation, simulation testing, and point calibration. The main and secondary keels 200 and the track hoisting device are then installed according to the calibrated points. The track hoisting device disclosed in this application can be controlled by a motor to move a multi-functional mechanical device, with guide rails and steel cables 16 as auxiliary mechanisms, to a designated position in a plane. This multi-functional mechanical device can perform point calibration, precise distance measurement, and remote sensing transmission, and can also hoist and clamp curved glass curtain walls. The entire process is simulated in real-time using BIM technology, with feedback and follow-up. This application employs a multi-functional mechanical mechanism for the hoisting of curtain wall panels and the measurement work before hoisting. By arranging a supporting guide rail mechanism on the top of the building, it ensures that the multi-functional mechanical mechanism can accurately move and transport the curtain wall panels within a preset range.

[0053] The supporting guide rail mechanism includes a base platform mounted on the top of the building and an extended guide rail 21 extending outward from the top of the building. The displacement driving mechanism includes a first moving motor 7 mounted on the extended guide rail, and the multi-functional mechanical mechanism is mounted on the first moving motor. The supporting guide rail mechanism includes a supporting column 22 mounted on the top of the building; a winch assembly 3 is mounted on the base platform 23, and the winch assembly includes connecting cables 24 connected to both ends of the extended guide rail. The winch assembly drives the extended guide rail to move up and down along the supporting column. In this embodiment, a counterweight 25 is set on the base platform according to the specifications of the curtain wall panels. The first moving motor mounted on the extended guide rail is a horizontal motor. The extended guide rail is composed of two channel steels, allowing the horizontal motor rollers to slide horizontally. The horizontal motor is a ring motor with a hole in the middle and a directional wheel at the bottom. The operator can remotely drive the motor to move left and right, thereby realizing the adjustment of the position of the multi-functional mechanical mechanism relative to the facade.

[0054] The machine platform is used to counterweight the extended guide rail to ensure that the displacement drive mechanism remains stable during the operation of the multi-functional mechanical mechanism. The extended guide rail extends outward from the top edge of the building facade. The first moving motor can drive the multi-functional mechanical mechanism to move in the near and far directions of the facade. Since the facade has various structures, the multi-functional mechanical mechanism can be moved back and forth to ensure the smooth completion of point marking and hoisting work.

[0055] The winch assembly is used to control the overall height and angle of the extended guide rail. When the building facade is an inclined or curved structure, the winch assembly adjusts the angle of the multi-functional mechanical mechanism by controlling the height of both ends of the extended guide rail to adapt to the building facade structure, ensuring more accurate and reasonable point measurement and hoisting positions.

[0056] The multifunctional support mechanism includes a drive module 11, a base 5 on the drive module, a rotating track 14 on the base, and a pair of distance measuring sliders 4 on the rotating track. Several lifting rods 15 are arranged along the edge of the drive module, and suction cups are attached to the top of each lifting rod. The distance measuring sliders are slidably mounted on the rotating track. Each distance measuring slider includes a wireless transmission module 43 and a laser distance measuring module. A drive motor 41 is also mounted on the distance measuring slider, and a drive track 42 is connected between the drive motor and the distance measuring slider. The base includes a wireless transmission ring 51, on which a fastener disc 52 is fixedly mounted. A track fastener 53 is fastened to the fastener disc, and the rotating track is welded to the track fastener. The drive module includes a brake motor 13, which includes a rotating central shaft 12 that passes through the base and is fixedly connected to the track fastener. Lifting motors 8 are located at each of the four corners of the drive module, and the lifting rods are connected to the lifting motors.

[0057] The distance measuring slider can move inward and outward along the radius of the base, making it more flexible in use. It can reduce its occupied space before reaching the desired position to avoid interference with other objects, and then expand outward to obtain a sufficient measurement range when ready to measure, resulting in excellent practical performance. The distance measuring slider is driven by a transmission motor to rotate a transmission track, allowing it to reciprocate on a rotating track to adjust its coverage area. The rotating track can rotate 360 ​​degrees on the base, enabling the line connecting the two distance measuring sliders to cover the entire plane, effectively increasing the distance measuring range. It can flexibly and conveniently reach the target position when facing various structural facades, using a laser distance measuring module for distance measurement, and can also measure flatness through scanning. Combining the laser distance measuring module with a BIM system can improve the accuracy of the building information model. The distance measuring slider has its own remote sensing and transmission device, which can remotely sense and measure distance and curvature, transmit real-time data, check the accuracy of point calibration, determine the curvature of the wall, and can interface with the BIM system in real time. The wireless transmission ring includes a horizontal sensing instrument and a wireless transmission instrument, which can sense the current angular position of the ranging rotating track. The track fastener transmits the power provided by the brake motor's self-rotating central shaft to the rotating track, ensuring that the rotating track can carry the ranging slider for accurate measurement. Except for the multi-functional mechanical mechanism which is not performing glass adsorption, the lifting motor keeps the lifting rod within the drive module to avoid positional interference. When it is necessary to hoist the curtain wall panel, the lifting motor drives the lifting rod to extend. Operators can install suction cups at the ends of the lifting rods. The suction cup specifications can be selected according to the size and shape of the curtain wall panel. After installation, it is ensured that the curtain wall panel is stably connected to the suction cups of each lifting rod, ensuring safe and stable hoisting operations.

[0058] In this embodiment, the size of the channel steel is not specified; it only needs to be suitable for the size of the horizontal motor's directional wheel during factory manufacturing. Pulleys must be installed at all cable bends to assist in directional changes.

[0059] The size of the multifunctional mechanical device is based on the actual production in the factory. In principle, the length of the rotating track should be no less than 1 to 2 times the longest side of the largest glass curtain wall panel of the building to be installed, and the sum of the areas of the top suction cups of the telescopic suction cups should be no less than 25% of the glass curtain wall panel.

[0060] When connecting each unit of the curtain wall frame material or unitized curtain wall to the connector, the entire curtain wall should be inspected and corrected, and then the connector should be welded to the embedded parts of the main structure (including anchoring with expansion bolts).

[0061] The gaps in the unitized curtain wall should be sealed with V-shaped, W-shaped or other adhesive strips and filled completely without any omissions.

[0062] The installation of unitized curtain wall glass should be carried out according to the design drawings. After the glass is installed in place, it should be fixed to the frame with rubber strips or other filler materials in a timely manner. Temporary fixing or leaving it suspended is not allowed.

[0063] When selecting steel cables, it is necessary not only to ensure that they can withstand the maximum load that occurs once every 50 years, but also to consider visual and psychological feelings. It is recommended to use 1*37 diameter 20 stainless steel stranded wire, which has a minimum breaking force of 21KN. 1Cr18Ni9 austenitic stainless steel should be used as the material for the support system (struts, etc.).

[0064] The installation accuracy of the device directly determines the precision of the glass curtain wall hoisting position. Therefore, by using BIM technology for modeling and positioning, the movable two-dimensional positioning error of the steel cables, struts, and each pulley support point must be controlled within 1cm, and the third-dimensional positioning error within 3mm.

[0065] All materials and equipment of the device are first modeled in the BIM system according to the national architectural model and actual site requirements, and then collision tests and simulation experiments are conducted. After passing the tests, the data is output, and then all components are prefabricated in the prefabrication plant according to the data.

[0066] Example 2

[0067] This embodiment also discloses the method of using the curtain wall track hoisting and positioning device based on the BIM system in Embodiment 1, including the following steps:

[0068] S1: Construct a building model of the curtain wall panels to be installed using a BIM system, and conduct collision tests and simulation experiments;

[0069] S2: Mark the anchor points of the track hoisting device according to the shape of the building facade, and install the support guide rail mechanism according to the anchor points;

[0070] S3: Install the multi-functional mechanical mechanism and displacement drive mechanism on the support guide rail mechanism, and ensure that the multi-functional mechanical mechanism is connected to the BIM system during installation;

[0071] S4: Construction begins. A pair of distance measuring sliders slide to the closest distance, and the winch assembly lowers the outer guide rail so that the multi-functional mechanical mechanism reaches the position where the curtain wall panel is to be installed.

[0072] S5: The drive module controls the rotating track to rotate and stop at each preset angle, and drives the distance measuring slider to measure the building information parameters at each preset angle through the transmission motor;

[0073] S6: The winch assembly lowers the multi-functional mechanical mechanism to the position where the glass to be hoisted is placed, the drive module drives the lifting rod to attract the glass to be hoisted, and the winch assembly lifts the multi-functional mechanical mechanism to the top;

[0074] S7: A pair of distance measuring sliders slide to their farthest distance, the winch assembly lowers the multi-functional mechanical mechanism to the curtain wall panel installation position, the distance measuring sliders move closer to each other and to the keel of the curtain wall panel installation position, the lifting rod drives the curtain wall panel to move closer to the curtain wall panel installation position, and the installation is completed manually.

[0075] The construction process for installing curtain wall panels includes: measuring and setting out lines → checking the position of the pre-embedded T-slots → inserting screws → fixing brackets → accurately aligning brackets → welding brackets → roughly hanging V-shaped and W-shaped tapes → hoisting the curtain wall and padding it with shock-absorbing rubber pads → tightening screws → adjusting the straightness of the curtain wall → filling with hot-pressed windproof strips → installing interior window sills and inner corner braces → filling the space between beams and columns with fireproof and thermal insulation materials.

[0076] Before using the BIM-based curtain wall track hoisting and positioning device, a model is first constructed using BIM technology, and collision and simulation experiments are conducted to mark the anchoring points of the track hoisting device. The panels are then anchored at the anchoring points, and the track hoisting device is installed, ensuring it is perpendicular to the wall surface. After installation, the device can be used in various construction processes, such as measurement and layout, checking the position of embedded T-slots, locating the support brackets, adjusting the straightness of the curtain wall, or other situations requiring point marking, precise distance measurement, flatness testing, and positioning. During use, first tighten the distance measuring slider, then lower the multi-functional mechanical device to the designated position using the winch assembly. Next, remotely rotate the track to the designated position and open the distance measuring slider outwards, waiting for the distance measuring slider to transmit the distance data. Repeat the process of remotely rotating the track and opening the distance measuring slider until all distance measurement steps are completed. During hoisting and installation, the multi-functional mechanical device is first quickly lowered using two winches. Then, based on BIM simulation calculations and the floor plan data and curvature of the area to be installed, a telescopic suction cup extends to the specified length and lifts the glass curtain wall panel to be hoisted. It is then quickly raised to the top, and the distance measuring slider is extended to its maximum distance. Subsequently, a remotely controlled horizontal motor moves the device to the designated point for lowering. First, the steel cables of both winches are lowered. Upon reaching the designated point, one winch is fixed while the other is lowered until the installation point is reached, thus satisfying the "fast first, slow later" lowering method to ensure safety and efficiency. After reaching the designated potential, the distance measuring slider retracts to the clamping position on the keel, the telescopic suction cup extends, and finally, the curtain wall panel is installed. The above steps are then repeated until all curtain wall panels are installed. The installation sequence should, in principle, follow the principle of "bottom to top, left to right."

[0077] It is worth noting that during construction, the BIM system should be connected and simulated in real time. The multi-functional mechanical device in the initial state is mainly used for multiple steps in the construction process, such as measurement and layout, checking the position of the embedded T-slots, locating the support and adjusting the straightness of the curtain wall. Its main functions are flatness detection, distance detection and quality control.

[0078] Example 3

[0079] In this embodiment, the supporting guide rail mechanism is further provided with a transverse guide rail 6 arranged along the width direction of the facade. The displacement driving mechanism includes a second moving motor 9 disposed on the transverse guide rail. The second moving motor drives the base and support column to move along the transverse guide rail. The transverse guide rail is arranged along the width direction of the facade, enabling the entire track hoisting mechanism to move within a certain range in the width direction of the building facade. Obviously, the shape of the transverse guide rail is set to correspond to the shape of the building facade, including but not limited to straight, curved, and V-shaped types. The multi-functional mechanical mechanism that can move in close contact with the facade surface can more flexibly assist in the precise installation of curtain wall panels, especially small-sized curtain wall panels. This avoids increasing the workload of operators due to misalignment in the width direction, eliminating the need for additional pulling devices to readjust the position of the curtain wall panels attached to the multi-functional mechanical mechanism, and ensuring that each curtain wall panel can be aligned with the installation position. A transverse guide rail is installed at the top of the facade. Several sets of curtain wall track hoisting and positioning devices based on the BIM system proposed in this application can be installed on the transverse guide rail. Each extended guide rail is equipped with a multi-functional mechanical mechanism. This allows multiple sets of multi-functional mechanical mechanisms to work simultaneously, significantly improving the efficiency of curtain wall construction.

[0080] In addition to the above embodiments, within the scope disclosed in the claims and specification of this invention, the technical features of this invention can be reselected and combined to form new embodiments. These can be achieved by those skilled in the art without creative effort. Therefore, these embodiments not described in detail in this invention should also be regarded as specific embodiments of this invention and within the protection scope of this invention.
