Description

Technical Field

[0001] This invention relates to the field of building curtain wall construction technology, and in particular to a device and construction method suitable for leveling and installing aluminum ceiling panels for large-area curtain walls. Background Technology

[0002] In building curtain wall construction, large-area aluminum composite panel curtain walls are widely used due to their aesthetic appeal and durability. Traditional installation of large-area aluminum composite panel curtain walls typically employs a leveling process of "installing the main and secondary keels first, then installing the panels." This process has the following problems:

[0003] 1. Flatness control is difficult and cumulative errors are uncontrollable: In high-altitude working environments, the installation accuracy of a single keel is not easy to guarantee. The keel error and the deformation of the panel are superimposed, resulting in the overall flatness exceeding the limit, which ultimately leads to poor installation flatness of the aluminum ceiling panel curtain wall (with appearance defects such as wavy and unevenness).

[0004] 2. High-altitude operations are risky and have low leveling efficiency: When leveling the main and secondary keels, the elevation and position of each keel need to be adjusted one by one on the suspended platform or lifting platform. The leveling of a single keel takes more than 30 minutes. Adjusting the flatness at high altitude is very time-consuming and laborious, and poses great safety hazards.

[0005] Therefore, there is a need for a device and construction method suitable for leveling and installing aluminum ceiling panels on large-area curtain walls, which can solve the problems of poor flatness during installation and time-consuming and laborious high-altitude flatness adjustment in the existing technology. Summary of the Invention

[0006] The purpose of this invention is to provide a device and construction method for leveling and installing aluminum ceiling panels for large-area curtain walls, which can solve the problems of poor flatness during installation of aluminum ceiling panel curtain walls and the time-consuming and laborious process of adjusting flatness at high altitudes in the prior art.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows:

[0008] A device and its construction method for leveling and installing aluminum ceiling panels for large-area curtain walls include: a leveling platform, a keel positioning component, and a measuring system; the bottom of the leveling platform is equipped with several leveling legs at intervals, allowing the work surface of the leveling platform to be adjusted to a horizontal state through the leveling legs; the keel positioning component is set on the work surface of the leveling platform and located at one end of the work surface, the main keel and secondary keel are connected on the keel positioning component to form a keel assembly, the work surface of the leveling platform is provided with several fine-tuning support feet at intervals, several sets of keel assemblies are spliced ​​on the work surface of the leveling platform, and the height of the keel assembly is adjusted by the fine-tuning support feet to form a curtain wall keel unit with a flat surface; the measuring system is installed on the leveling platform and the curtain wall keel unit to measure the flatness of the curtain wall keel unit.

[0009] The measurement system includes laser emitters installed at the four corners of the leveling platform work surface and several laser receiving targets magnetically attached to the curtain wall keel unit. The laser receiving targets receive the laser beams emitted by the laser emitters.

[0010] The measurement system also includes a data processing terminal, which is wirelessly connected to the laser receiving target and is used to store the measurement data of the laser receiving target.

[0011] A construction method for a device suitable for leveling and installing aluminum ceiling panels on large-area curtain walls includes the following steps:

[0012] Step 1: Level the leveling platform on the ground and install the laser emitter of the measuring system at the corner of the worktable of the leveling platform;

[0013] Step 2: Position and install the main keel and assemble and fix the secondary keel using the keel positioning components to form the keel assembly;

[0014] Step 3: Several sets of keel components are spliced ​​on the workbench of the leveling platform to form a curtain wall keel unit, and the flatness of the curtain wall keel unit is monitored by a measurement system;

[0015] Step 4: The data processing terminal of the measurement system determines whether the flatness of the monitored curtain wall keel unit meets the construction requirements based on the measurement data. If yes, proceed to step 5; otherwise, activate the alarm and adjust the flatness of the curtain wall keel unit by fine-tuning the support feet until the flatness of the curtain wall keel unit meets the construction requirements.

[0016] Step 5: The entire curtain wall keel unit is hoisted into place;

[0017] Step 6: Install the curtain wall keel unit onto the building structure using embedded parts;

[0018] Step 7: Install the aluminum panels onto the curtain wall keel unit;

[0019] Step 8: Repeat steps 2 to 7 to complete the installation of all aluminum panels and form an aluminum panel curtain wall.

[0020] In step 1, two workers use an electronic level to measure from the four corners and center of the leveling platform. By adjusting the level of the worktable using the four leveling legs, the levelness of the worktable is made ≤0.5mm / m.

[0021] Step 3 includes the following sub-steps:

[0022] Step 31: Install connectors and lifting points on the keel assembly, and perform surface treatment on the keel assembly;

[0023] Step 32: Arrange several measurement points at intervals along the length of the main keel and secondary keel, and magnetically arrange a laser receiving target at each measurement point;

[0024] Step 33: Set the measurement frequency in the data processing terminal of the measurement system, and perform laser grid scanning on the surface of the curtain wall keel unit according to the measurement frequency using a laser transmitter and a laser receiving target;

[0025] Step 34: The data processing terminal collects and stores the measurement data of the laser receiving target.

[0026] In step 32, the distance between two adjacent measurement points shall not exceed 500mm, and the measurement points shall be mainly arranged at the splice joints of the keel components and the mid-span of the curtain wall keel units.

[0027] Step 5 includes the following sub-steps:

[0028] Step 51: Selection of hoisting equipment and auxiliary tools;

[0029] Step 52: Conduct a trial lift. The lifting equipment slowly raises the hook to lift the curtain wall keel unit 30cm off the ground, and checks the force on the clamps of the auxiliary tools and the deformation of the main and secondary keels of the curtain wall keel unit.

[0030] Step 53: After the trial lift is successful, the hoisting equipment slowly lifts the curtain wall keel unit. During the lifting process, the coordinates of the four corners of the curtain wall keel unit are detected in real time through the measurement system. Based on the monitoring data of the measurement system, the operator adjusts the attitude and position of the curtain wall keel unit by adjusting the rotation angle of the hoisting equipment to ensure that the curtain wall keel unit rises along the designed trajectory.

[0031] Step 6 includes the following sub-steps:

[0032] Step 61: Install the embedded parts on the building structure according to the design position. After the curtain wall keel unit is raised to the installation height by the hoisting equipment, the hoisting equipment slowly rotates back to align the positioning line on the curtain wall keel unit with the embedded parts.

[0033] Step 62: Workers use a platform to temporarily fix the connectors on the curtain wall keel unit to the embedded parts with bolts;

[0034] Step 63: An elongated hole with a diameter larger than that of the bolt is formed on the connector. The position of the curtain wall keel unit is finely adjusted through the elongated hole to ensure that the installation posture and position of the curtain wall keel unit are accurate and without deviation. Tighten the bolt.

[0035] Step 64: Weld the reinforcing connectors and embedded parts to permanently fix the curtain wall keel unit to the building structure.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. This invention assembles curtain wall keel units on the ground using a leveling platform and adjusts the surface flatness of the curtain wall keel units. The ground assembly environment is better than that at high altitudes, which can effectively improve the flatness adjustment accuracy and efficiency of the curtain wall keel units. This provides an extremely flat installation foundation for aluminum ceiling panels and saves a lot of time on high-altitude measurement and adjustment. It solves the problems of high-altitude leveling operations being difficult, time-consuming, labor-intensive, inaccurate, and posing significant safety hazards, and can significantly improve the installation flatness and construction efficiency of aluminum ceiling panel curtain walls.

[0038] 2. This invention allows the installation and leveling of the curtain wall keel unit to be carried out on the ground, which greatly reduces the time and risk of high-altitude operations and the interference of human factors in high-altitude operations. It can significantly improve construction safety and help ensure the stable construction quality and standardized process of aluminum ceiling panel curtain walls.

[0039] 3. This invention hoists the curtain wall keel unit assembled on the ground into place in one go, which significantly improves the installation efficiency of aluminum ceiling panels, helps to shorten the construction period, reduce labor, machinery shifts and safety investment, reduce costs and increase efficiency, and can be applied to curtain wall projects with various complex shapes and large areas.

Detailed Implementation

[0047] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more comprehensive overview of the device and construction method for leveling and installing aluminum ceiling panels for large-area curtain walls proposed in this invention. The advantages and features of this invention will become clearer from the following description and claims. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, intended only to facilitate and clarify the illustration of the embodiments of this invention.

[0048] Please see the appendix Figure 1 and attached Figure 3 A device for leveling and installing aluminum ceiling panels for large-area curtain walls includes a leveling platform 1, a keel positioning component 2, and a measuring system. Several leveling legs 11 are installed at intervals on the bottom of the leveling platform 1, allowing the work surface of the leveling platform 1 to be adjusted to a horizontal state. The keel positioning component 2 is set on the work surface of the leveling platform 1 and located at one end of the work surface. The main keel and secondary keel are connected on the keel positioning component 2 to form a keel assembly 9. Several fine-tuning support feet (not shown in the figure) are provided at intervals on the work surface of the leveling platform 1. Several sets of keel assemblies 9 are spliced ​​on the work surface of the leveling platform 1, and the height of the keel assemblies 9 is adjusted by the fine-tuning support feet to form a flat curtain wall keel unit 10. The measuring system is installed on the leveling platform 1 and the curtain wall keel unit 10 to measure the flatness of the curtain wall keel unit 10.

[0049] Preferably, the length of the leveling platform 1 is equal to the maximum length of the curtain wall keel unit 10 plus 2m, and the width of the leveling platform 1 is equal to the maximum width of the curtain wall keel unit 10 plus 2m, to allow space for splicing construction. The work surface of the leveling platform 1 can be made of a rectangular welded steel frame + 20mm thick steel plate, forming a platform for assembling the keel assembly 9 and the curtain wall keel unit 10. The leveling legs 11 can be hydraulic legs with an adjustment accuracy of ±5mm / m using existing technology. Four leveling legs 11 are provided, located at the four corners of the work surface, for adjusting the levelness of the work surface.

[0050] The keel positioning component 2 can be made of 50*50*4mm hot-dip galvanized angle steel welded together. The shape and size of the keel positioning component 2 are determined according to the shape and size of the keel assembly 9, so that the main keel and secondary keel can be accurately positioned on the keel positioning component 2, thereby splicing them to form the keel assembly 9. The main keel and secondary keel are first spliced ​​into the smallest unit keel assembly 9, and then each keel assembly 9 is spliced ​​on the workbench to form a curtain wall keel unit 10 that is hoisted in one go.

[0051] Preferably, the fine-tuning support feet can be made using existing jacks or precision screws with an adjustment accuracy of 0.1mm. The fine-tuning support feet are used to lift or lower the keel components 9, so that the surface flatness of each keel component 9 after splicing into the curtain wall keel unit can be controlled at the millimeter level, so that aluminum ceiling panels can be directly installed after the overall hoisting is completed.

[0052] Please see the appendix Figure 1 The measurement system includes laser emitters 3 installed at the four corners of the work surface of the leveling platform 1 and several laser receiving targets 4 magnetically attached to the curtain wall keel unit 10. The laser receiving targets 4 receive the laser beams emitted by the laser emitters 3.

[0053] Select appropriate laser transmitter 3 and laser receiver target 4 for construction to ensure signal matching, interference-free transmission, and effective range that meets actual site requirements.

[0054] The measurement system also includes a data processing terminal (not shown in the figure), which is wirelessly connected to the laser receiving target 4 and is used to store the measurement data of the laser receiving target 4.

[0055] The data processing terminal can use existing computer equipment to collect and store the measurement data of the laser receiving target 4, and determine the surface flatness of the curtain wall keel unit 10 based on the measurement data.

[0056] Please see the appendix Figure 1 To be continued Figure 5 A method for leveling aluminum ceiling panels suitable for large-area curtain walls includes the following steps:

[0057] Step 1: Level the leveling platform 1 on the ground and install the laser emitter 3 of the measuring system at the corner of the worktable of the leveling platform 1.

[0058] Specifically, two workers use an electronic level with an accuracy of 0.02mm to measure from the four corners and center of the leveling platform 1. By adjusting the level of the worktable by adjusting the four leveling legs 11, the level of the worktable is made ≤0.5mm / m.

[0059] Leveling the work surface using an electronic level is a standard procedure in this field and will not be described in detail here.

[0060] Step 2: Position and install the main keel and assemble and fix the secondary keel using the keel positioning component 2 to form the keel assembly 9.

[0061] The keel assembly 9 is the smallest unit of the keel system in the aluminum ceiling panel curtain wall. The main keel and secondary keel are precisely positioned by the keel positioning component 2, and the main keel and secondary keel are welded together according to the design requirements.

[0062] Welding the main keel and the secondary keel to form the keel assembly 9 is a standard operation in this field and will not be described in detail here.

[0063] Step 3: Several sets of keel components 9 are spliced ​​on the workbench of the leveling platform 1 to form curtain wall keel units 10, and the flatness of the curtain wall keel units 10 is monitored by a measurement system.

[0064] Step 3 includes the following sub-steps:

[0065] Step 31: Install connectors 6 and lifting points 7 on the keel assembly 9, and perform surface treatment on the keel assembly 9.

[0066] Specifically, an angle grinder can be used to remove weld beads, burrs, etc. from the surface of the main keel and secondary keel, with a focus on removing the contact area of ​​the laser receiving target 4 to ensure that the laser receiving target 4 can fit tightly with the surface of the main keel and secondary keel without gaps.

[0067] Preferably, the connector 6 can be made of angle steel and installed on the side where the keel assembly 9 connects to the building structure 8. The suspension point 7 is installed on the top of the keel assembly 9. The number of connectors 6 and suspension points 7 can be adjusted according to actual construction needs.

[0068] Step 32: Arrange several measurement points at intervals along the length of the main keel and secondary keel, and magnetically arrange a laser receiving target 4 at each measurement point.

[0069] Preferably, the distance between two adjacent measurement points does not exceed 500mm, and the measurement points are mainly arranged at the splice seams of the keel assembly 9 and the span of the curtain wall keel unit 10. During installation, the laser receiving target 4 and the laser emitter 3 should be located in the same horizontal plane. If the surface of the curtain wall keel unit 10 is not flat, there will be a height difference between the laser receiving target 4 and the laser emitter 3. Then, there will be an angle between the laser beam received by the laser receiving target 4 and the horizontal line. The laser receiving target 4 converts this angle into a height difference, which is the measurement data, that is, the surface flatness deviation of the curtain wall keel unit 10.

[0070] The laser receiving target 4 is installed on the main keel and secondary keel by magnetic attraction, which is convenient and quick to install and remove. When installing by magnetic attraction, it is necessary to ensure that the laser receiving target 4 is precisely aligned with the measurement point.

[0071] Step 33: Set the measurement frequency in the data processing terminal of the measurement system according to the actual usage requirements, and perform laser grid scanning on the surface of the curtain wall keel unit 10 according to the measurement frequency through the laser transmitter 3 and the laser receiving target 4.

[0072] Laser emitter 3 emits laser beams in different directions toward curtain wall keel unit 10. Each laser beam is received by laser receiving target 4 at a different location, forming a laser grid scan on the surface of curtain wall keel unit 10. Laser emitter 3 and laser receiving target 4 are commonly used laser scanning detection methods in this field, and their working process and working principle will not be described in detail here.

[0073] Step 34: The data processing terminal collects and stores the measurement data of the laser receiving target 4.

[0074] Step 4: The data processing terminal of the measurement system determines whether the flatness of the monitored curtain wall keel unit 10 meets the construction requirements (e.g., flatness deviation ≤ 2mm / m) based on the measurement data. If yes, proceed to step 5; otherwise, activate the alarm and adjust the flatness of the curtain wall keel unit 10 by fine-tuning the support feet until the flatness of the curtain wall keel unit 10 meets the construction requirements.

[0075] Preferably, alarms can be implemented using methods such as sound alarms, light alarms, background pop-up alarms, and push notification alarms, depending on actual construction needs.

[0076] Step 5: The curtain wall keel unit 10 is hoisted into place as a whole.

[0077] Step 5 includes the following sub-steps:

[0078] Step 51: Selection of hoisting equipment and auxiliary tools.

[0079] The appropriate hoisting equipment is selected based on the weight of the hoisting keel, the hoisting height, and the working radius; a truck crane is generally used. Auxiliary tools include steel wire ropes with rubber pads and clamps to fix the hoisting curtain wall keel unit 10. A measurement system (including a laser transmitter, a laser receiving target, and a data terminal) is used for real-time monitoring during hoisting.

[0080] The hoisting equipment and auxiliary tools are commonly used hoisting tools in this field, and will not be described in detail here.

[0081] Step 52: Conduct a trial lift. The lifting equipment slowly raises the hook, so that the curtain wall keel unit 10 is 30cm off the ground, and checks the force on the clamps of the auxiliary tools and the deformation of the main keel and secondary keel of the curtain wall keel unit 10.

[0082] If the stress on the auxiliary tool clamps and the deformation of the main and secondary keels of the curtain wall keel unit 10 are all within the construction safety range, then the trial lifting is qualified; otherwise, the trial lifting is unqualified.

[0083] Step 53: After the trial lifting is successful, the hoisting equipment slowly lifts the curtain wall keel unit 10. During the lifting process, the four corner coordinates of the curtain wall keel unit 10 are detected in real time through the measurement system. Based on the monitoring data of the measurement system, the operator adjusts the attitude and position of the curtain wall keel unit 10 by adjusting the rotation angle of the hoisting equipment to ensure that the curtain wall keel unit 10 rises along the designed trajectory.

[0084] Measuring the four corner coordinates of the curtain wall keel unit 10 using a laser emitter 3 and a laser receiving target 4, determining the attitude and position of the curtain wall keel unit 10 based on the four corner coordinates, and controlling the attitude and position of the curtain wall keel unit 10 by controlling the rotation angle of the hoisting equipment are conventional hoisting techniques for the curtain wall keel unit 10 in this field, and will not be elaborated here.

[0085] Step 6: Install the curtain wall keel unit 10 onto the building structure 8 through the embedded part 5.

[0086] Step 6 includes the following sub-steps:

[0087] Step 61: Install the embedded part 5 on the building structure 8 according to the design position. After the curtain wall keel unit 10 is raised to the installation height by the hoisting equipment, the hoisting equipment slowly rotates back to align the positioning line on the curtain wall keel unit 10 with the embedded part 5.

[0088] Preferably, the embedded part 5 can be composed of channel steel and anchor bolts, and is pre-embedded and installed on the curtain wall mounting surface of the building structure 8 during the construction of the building structure 8. The pre-embedding and installation of the embedded part 5 is a conventional operation in this field, and will not be described in detail here.

[0089] Step 62: Workers use a platform to temporarily fix the connectors 6 on the curtain wall keel unit 10 to the embedded parts 5 with bolts.

[0090] Step 63: An elongated hole 61 with a diameter larger than that of the bolt is formed on the connector 6. The position of the curtain wall keel unit 10 is finely adjusted through the elongated hole 61 to ensure that the installation posture of the curtain wall keel unit 10 is accurate and without deviation. Tighten the bolt.

[0091] Preferably, the diameter of the elongated hole 61 is 3mm larger than the bolt diameter, allowing the position of the connector 6 to be adjusted upwards, downwards, leftwards, and rightwards relative to the embedded part 5, thereby ensuring that the installation posture and position of the curtain wall keel unit 10 are accurate and without deviation.

[0092] Step 64: Weld the reinforcing connector 6 and the embedded part 5 to permanently fix the curtain wall keel unit 10 to the building structure 8.

[0093] After welding and reinforcement are completed, clean the dust from the joints and apply sealant to ensure reliable connection.

[0094] Step 7: Install the aluminum ceiling panels onto the curtain wall keel unit 10.

[0095] The aluminum panels are installed on the curtain wall keel unit 10 using conventional installation techniques, which will not be described in detail here.

[0096] Step 8: Repeat steps 2 to 7 to complete the installation of all aluminum panels and form an aluminum panel curtain wall.

[0097] When this invention was applied to an airport connection line project, the following specific technical effects were obtained through statistical analysis:

[0098] index Traditional methods This invention flatness error ≤5mm / m ≤2mm / m working hours 1.5h / m2 0.4h / m2 High-altitude operations percentage 80％ 15％ rework rate 15％ ≤2％

[0099] As can be seen from the table above, the present invention can significantly improve the flatness of aluminum ceiling panels during installation, shorten working hours, and reduce the proportion of high-altitude operations and rework rate.
