Description

Technical Field

[0001] The present invention relates to the technical field of curtain wall construction, in particular to a high-efficiency measurement and construction method for a building curtain wall. Background Art

[0002] As an important component of the exterior protective structure of modern high-rise buildings, the greatest feature of the building curtain wall is that it organically combines the building's function, structure, energy saving, aesthetics and other factors, giving the building a unique style and agile temperament.

[0003] In traditional curtain wall construction, a total station is typically used to measure the building's outline to determine the installation location and production dimensions of curtain wall units. However, this measurement method is not only inefficient but also susceptible to environmental influences, resulting in low measurement accuracy. This, in turn, requires frequent adjustments to curtain wall units during installation, increasing construction costs and extending construction schedules.

[0004] To address this problem, the present invention proposes an efficient measurement and construction method for building curtain walls, aiming to improve measurement accuracy and construction efficiency and reduce construction costs. Summary of the Invention

[0010] Step 3: Measurement and layout: Extract the installation point data of the curtain wall keel from the BIM model. The on-site construction personnel will lay out the installation standard lines for fixing the embedded panels and curtain wall keels based on the point data.

[0011] Step 4: Install the fixed embedded plate and curtain wall keel: Install the fixed embedded plate according to the standard line set in step 3, and then connect the curtain wall keel to the fixed embedded plate. During the installation process, use a laser level and a plumb line to monitor in real time and adjust the keel position in time to ensure that the installation position of the keel meets the design requirements;

[0012] Step 5: Install exterior wall insulation: Precisely cut the insulation according to the layout of the insulation in the BIM model. Then, install the insulation between the exterior wall and the curtain wall studs.

[0013] Step 6. Curtain wall aluminum panel installation: Connect the curtain wall aluminum panels to the curtain wall keels one by one according to the set installation position;

[0014] Step 7: Gluing and cleaning the surface of the curtain wall aluminum panels: After the curtain wall aluminum panels are installed, glue the gaps between the curtain wall aluminum panels. After gluing, clean the surface of the curtain wall aluminum panels to remove surface stains and dust to keep the curtain wall clean and beautiful.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. The efficient measurement and construction method for building curtain walls described in the present invention utilizes a 3D scanner to accurately measure the main structure of a building, thereby accurately obtaining the building's 3D contour data. This avoids data errors in traditional measurement methods and improves measurement accuracy. Furthermore, after establishing a BIM model using the acquired 3D building contour data, curtain wall units are designed and optimized, ensuring a perfect match between the curtain wall units and the main structure of the building, reducing the number of adjustments during installation and thus improving construction efficiency. Furthermore, a modular installation method is employed to assemble and install the processed curtain wall units according to design requirements, thereby achieving rapid, efficient, and precise construction of the curtain wall and further reducing construction costs.

[0028] 2. The present invention relates to an efficient measurement and construction method for a building curtain wall. During the docking operation of the two main uprights, the connecting plate is used in conjunction with the pin rod to establish a temporary connection between the main uprights. During the operation, the construction workers do not have to always support the main uprights to be installed, which reduces the labor intensity of the construction workers. At the same time, since the two main uprights are temporarily connected when docked, falling objects from high altitudes are avoided, thereby improving the safety of construction. Furthermore, by changing the relative position of the pin rod in the adjustment slide hole, the position of the main upright to be installed can be fine-tuned, thereby improving the convenience and flexibility of the installation of the main upright. Furthermore, by utilizing the gravity of the main upright to be installed, the adapter is brought into contact with the fixed plate before welding, which can temporarily fix the adapter and improve the convenience of the welding operation. On the other hand, displacement of the adapter during welding is avoided, thereby ensuring the accuracy of the welding position and avoiding the gap between the adapter and the fixed plate, thereby improving the quality of welding.

[0029] 3. The present invention relates to an efficient measurement and construction method for building curtain walls. When the sealant between the aluminum panels of the curtain wall ages and cracks, rainwater seeps through the gaps between the aluminum panels of the curtain wall and is first absorbed by the liquid-absorbing pad arranged on the front of the isolation plate. As the amount of water absorbed increases, the liquid-absorbing pad gradually expands, pushing the supporting plate to slide upward along the height direction of the first limiting plate. When the plane of the supporting plate is flush with the top of the first limiting plate to form a second matching shape, the compressed elastic potential energy of the spring push rod is released, pushing the bottom of the thermal insulation cotton to move it toward the second accommodating area. The insulation cotton eventually forms an inclined position, spanning between the first and second accommodating areas. At this time, rainwater seeping in from the joints of the curtain wall aluminum panels is absorbed by the insulation cotton. Moreover, because the insulation cotton is inclined and spans between the first and second accommodating areas, the contact area between the water-absorbing insulation cotton and the building exterior wall and the dry insulation cotton on the left and right sides is greatly reduced. This effectively inhibits the spread and penetration of rainwater into the building exterior wall and the dry insulation cotton on the left and right sides. On the one hand, the risk of rainwater seeping into the building interior is reduced, and on the other hand, the area of ​​the insulation cotton damaged by moisture after water seepage is reduced, thereby reducing the repair cost of curtain wall leakage.

[0030] Furthermore, the insulation is tilted and spans between the first and second accommodating areas. After absorbing water and expanding, it can contact the curtain wall aluminum panels. This can partially seal cracks in the sealant caused by aging, slowing the rate of rainwater infiltration into the curtain wall and buying time for repairs. Furthermore, the expansion of the insulation compresses the curtain wall aluminum panels, causing them to bulge and deform. This allows repairers to quickly locate cracks in the sealant by observing the deformation of the panels, improving both timeliness and efficiency of repairs. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Example 1: Figures 5 to 7As shown, the efficient measurement and construction method of a building curtain wall according to the present invention comprises the following steps:

[0046] Step 1: Scanning and modeling: Conduct a 3D scan of the completed building facade, compare the actual building facade outline with the design drawings, and then create a BIM model;

[0047] Step 2: Cutting and producing curtain wall studs 4 and aluminum plates: Carry out detailed modeling of the curtain wall studs 4 and aluminum plates that have not been installed on the facade based on the BIM model, and complete the cutting and production of curtain wall studs 4 and aluminum plates;

[0048] Step 3: Measurement and setting out: Extract the installation point data of the curtain wall keel 4 from the BIM model. The on-site construction personnel lay out the installation standard lines for fixing the embedded plate 1 and the curtain wall keel 4 based on the point data.

[0049] Step 4: Install the fixed embedded plate 1 and curtain wall keel 4: Install the fixed embedded plate 1 according to the standard line set in step 3, and then connect the curtain wall keel 4 to the fixed embedded plate 1. During the installation process, use a laser level and a plumb line to monitor in real time and adjust the keel position in time to ensure that the installation position of the keel meets the design requirements;

[0050] Step 5: Install the exterior wall insulation 21: Accurately cut the insulation 21 according to the layout design of the insulation 21 in the BIM model; then, install the insulation 21 between the exterior wall of the building and the curtain wall keel 4;

[0051] Step 6: Install the curtain wall aluminum panels: Connect the curtain wall aluminum panels one by one to the curtain wall keels 4 according to the set installation positions;

[0052] Step 7: Gluing and cleaning the surface of the curtain wall aluminum panels: After the curtain wall aluminum panels are installed, glue the gaps between the curtain wall aluminum panels. After gluing, clean the surface of the curtain wall aluminum panels to remove surface stains and dust to keep the curtain wall clean and beautiful.

[0053] By adopting the efficient measurement and construction method of a building curtain wall described in the present invention and accurately measuring the main structure of the building using a 3D scanner, the 3D contour data of the building can be accurately obtained, thereby avoiding data errors in traditional measurement methods and improving measurement accuracy; further, after establishing a BIM model using the acquired 3D contour data of the building, the curtain wall unit is designed and optimized, which can ensure a perfect match between the curtain wall unit and the main structure of the building, reduce the number of adjustments during the installation process, and thus improve construction efficiency; further, by adopting a modular installation method, the processed curtain wall units are assembled and installed according to design requirements, thereby realizing fast, efficient and precise construction of the curtain wall and further reducing construction costs.

[0054] Specifically, in this embodiment, Tianbao X7 is used to scan the facade of the building; the specific operation is: the top edge, bottom edge and facade of the scanned concrete structure of the building are used as the basis for modeling, and the model position of the top and bottom edges is based on the lowest point in the same plane position of the scan as the plane model elevation; the model position of the bottom edge, when there is a concrete structure, is based on the highest point of the steel plate position in the same plane as the plane model elevation, and when concrete pouring is not temporarily carried out, the highest point of the steel plate position is found as the elevation of the model plane according to the elevation of the placed steel plate; the outer plane of the building is used as a reference for the outer surface of the model according to the maximum value of the convexity of the actual point cloud;

[0055] The specific operations of data processing are: scanning the initial point cloud data → performing point cloud fitting through RealWorks → obtaining high-precision fitted point cloud data → eliminating unnecessary point cloud data → obtaining point cloud data that can be used for tax exemption;

[0056] In the construction of the BIM model, we adopted a segmented and regional approach to obtain a detailed model that meets the needs of the site. The model file is output in a format specific to Rhino software, and a true color point cloud file is also provided as a project reference.

[0057] As a preferred embodiment, based on the above method, further, in the scanning and modeling operation of step 1, the building facade is divided into multiple model sections, and then scanning and modeling are performed section by section according to the divided sections. With this structural setting,

[0058] Specifically, by dividing the building facade into multiple model sections, each section can be scanned and modeled independently. This not only avoids the difficulty of scanning and modeling due to the complex building facade, but also allows for simultaneous data collection for different sections, improving data collection efficiency. Furthermore, scanning and modeling each section facilitates on-site verification and correction by construction personnel, ensuring the accuracy and reliability of the BIM model.

[0059] Example 2: Figure 1 and Figure 2 As shown, the present invention describes an efficient measurement and construction method for a building curtain wall. On the basis of the above-mentioned method, further, the fixed embedded plate 1 includes a fixed flat plate 2 and an adapter 3, and the fixed flat plate 2 is connected to the facade of the building; the adapter 3 is vertically connected to the surface of the fixed flat plate 2; the curtain wall keel 4 includes a main vertical pole 5 and a cross bar 6, the main vertical pole 5 is vertically arranged, and the main vertical pole 5 and the adapter 3 are connected by bolts, and the cross bar 6 is connected between two adjacent main vertical poles 5, and the cross bar 6 is vertically arranged to the main vertical pole 5; when the main vertical pole 5 is connected to the adapter 3, the main vertical pole 5 is installed from the upper part to the lower part of the building.

[0060] In this embodiment, the main uprights 5 are installed from top to bottom, preventing collisions with the already installed and calibrated main uprights 5 during docking, thereby ensuring installation accuracy and stability. This installation method also makes it more convenient for construction workers and improves installation efficiency. In practice, the fixing plate 2 is secured to the building facade using expansion screws, and the adapter 3 is welded vertically to the surface of the fixing plate 2.

[0061] As a preferred embodiment, on the basis of the above-mentioned manner, further, one end of the main vertical pole 5 is further provided with an insertion rod 7, and the other end is provided with an adjustment slide hole 8, the cross-sectional size of the insertion rod 7 is smaller than the cross-sectional size of the main vertical pole 5, and when the two main vertical poles 5 are docked, the insertion rod 7 is inserted into the accommodating cavity inside the docked main vertical pole 5; with the central axis of the main vertical pole 5 as the dividing line, the side of the main vertical pole 5 close to the adapter 3 is the left area 9, and the other side is the right area 10; the adjustment slide hole 8 is set to The strip-shaped structure, the adjusting slide hole 8 is arranged across the left and right areas of the main vertical pole 5, the length of the adjusting slide hole 8 in the left area 9 is greater than the length in the right area 10; the adjusting slide hole 8 is arranged obliquely, and the height of the end of the adjusting slide hole 8 in the left area 9 is lower than the height of the end in the right area 10; a hanging plate 11 is also provided at the end of the insertion rod 7, and a detachable pin rod 12 is inserted in the adjusting slide hole 8. Hanging the hanging plate 11 on the pin rod 12 can establish a temporary connection between the two main vertical poles 5.

[0062] In this embodiment, when the two main vertical poles 5 are connected, the adapter 3 is first connected vertically to the main vertical pole 5 to be installed, and then the insertion rod 7 is inserted into the accommodating cavity of the installed main vertical pole 5. Then, the pin rod 12 is inserted into the adjusting slide hole 8, so that the hanging plate 11 is hung on the pin rod 12. After the temporary connection of the two main vertical poles 5 is established, the main vertical pole 5 to be installed drives the pin rod 12 to slide in the adjusting slide hole 8 under the action of its own gravity until the adapter 3 is connected to the fixed pole 5. The fixed plate 2 stops in contact. At this time, adjust the relative positions of the left and right sides of the main pole 5 to be installed so that the left and right side surfaces of the two main poles 5 are in the same plane, and then weld the adapter 3 to the fixed plate 2; then, separate the connection between the adapter 3 and the main pole 5 to be installed, adjust the distance between the main pole 5 to be installed and the fixed plate 2 so that the main pole 5 to be installed overlaps with the main pole 5 that has been installed above, and then use bolts to connect the main pole 5 to be installed and the adapter 3.

[0063] In this embodiment, when the construction workers are docking the two main uprights 5, they use the connecting plate 11 to cooperate with the pin rod 12 to establish a temporary connection between the main uprights 5. During the operation, the construction workers do not have to always support the main uprights 5 to be installed, which reduces the labor intensity of the construction workers. At the same time, since the two main uprights 5 are temporarily connected when docking, falling objects from high places are avoided, thereby improving the safety of construction. Furthermore, in this embodiment, by changing the relative position of the pin rod 12 in the adjustment slide hole 8, the position of the main upright 5 to be installed can be fine-tuned, thereby improving the convenience and flexibility of the installation of the main upright 5. Furthermore, by utilizing the gravity of the main upright 5 to be installed, the adapter 3 is brought into contact with the fixed plate 2 before welding, which can temporarily fix the adapter 3 and improve the convenience of the welding operation. On the other hand, the adapter 3 is prevented from being displaced during welding, ensuring the accuracy of the welding position, while avoiding the gap between the adapter 3 and the fixed plate 2, thereby improving the quality of the welding.

[0064] As a preferred embodiment, based on the above-mentioned method, the attachment plate 11 is further arranged on the side of the left area 9 of the main vertical pole 5. With this structural arrangement, when the attachment plate 11 is attached to the pin rod 12, the center of gravity of the main vertical pole 5 to be installed will be biased toward the side of the building facade. In this way, under the action of its own gravity, the main vertical pole 5 to be installed will automatically tilt toward the side of the building facade, making the contact between the adapter 3 and the fixing plate 2 closer, further improving the quality of the welding.

[0065] Example 3: Figure 1 、 Figure 3 and Figure 4 As shown, the efficient measurement and construction method of a building curtain wall described in the present invention, on the basis of the above method, further, the cross bar 6 is connected with an isolation plate 13, the isolation plate 13 is arranged in contact with the outer wall of the building, the front of the isolation plate 13 is provided with a first limiting plate 14, and the back is provided with a second limiting plate 15. The connection line between the first limiting plate 14 and the second limiting plate 15 is used as a dividing line to divide the space between adjacent isolation plates 13 into a first accommodating area 16 and a second accommodating area 17. The first accommodating area 16 is arranged on one side of the outer wall of the building, and the thermal insulation cotton 21 is arranged in the first accommodating area 16.

[0066] The first limiting plate 14 is further connected to a bearing plate 18, which is located in the first accommodating area 16. The bearing plate 18 can slide along the height direction of the first limiting plate 14. A liquid-absorbing pad 19 is further provided between the bearing plate 18 and the isolation plate 13. A spring push rod 20 is further provided on the outer wall of the building body, and the spring push rod 20 is arranged on one side of the bearing plate 18. The bearing plate 18 and the first limiting plate 14 have a first fitting form and a second fitting form.

[0067] In the first matching form, there is a height difference between the plane of the supporting plate 18 and the top of the first limiting plate 14. At this time, due to the obstruction of the first limiting plate 14 and the second limiting plate 15, the thermal insulation cotton 21 is stably fixed in the first accommodating area 16; when rainwater seeps in from the joint of the curtain wall aluminum plate, the absorbent pad 19 absorbs water and expands to push the supporting plate 18 to move upward. When the plane of the supporting plate 18 is flush with the top of the first limiting plate 14, the two form a second matching form; at this time, the elastic potential energy of the spring push rod 20 is released, pushing the bottom of the thermal insulation cotton 21 to move it toward the second accommodating area 17, and finally the thermal insulation cotton 21 forms an inclined state spanning between the first accommodating area 16 and the second accommodating area 17.

[0068] Specifically, in this embodiment, when the sealant between the curtain wall aluminum panels ages and cracks, rainwater seeps through the gaps between the curtain wall aluminum panels and is first absorbed by the liquid-absorbing pad 19 arranged on the front of the isolation plate 13; as the amount of water absorbed increases, the liquid-absorbing pad 19 gradually expands, pushing the supporting plate 18 to slide upward along the height direction of the first limiting plate 14; when the plane of the supporting plate 18 is flush with the top of the first limiting plate 14 to form a second matching shape, the compressed elastic potential energy of the spring push rod 20 is released, pushing the bottom of the thermal insulation cotton 21 to move it toward the second accommodating area 17; the thermal insulation cotton 21 finally forms an inclined The state spans between the first accommodating area 16 and the second accommodating area 17; at this time, rainwater seeping from the joints of the curtain wall aluminum panels is absorbed by the thermal insulation cotton 21, and because the thermal insulation cotton 21 is in an inclined state and spans between the first accommodating area 16 and the second accommodating area 17, the contact area between the water-absorbing thermal insulation cotton 21 and the building exterior wall and the dry thermal insulation cotton 21 on the left and right sides is greatly reduced, which effectively inhibits rainwater from spreading and penetrating into the building exterior wall and the dry thermal insulation cotton 21 on the left and right sides. On the one hand, the risk of rainwater seeping into the building interior is reduced, and on the other hand, the area of ​​the thermal insulation cotton 21 damaged by moisture after water seepage is reduced, thereby reducing the repair cost after curtain wall leakage;

[0069] Furthermore, in this embodiment, the insulation 21 is tilted and spans between the first and second accommodating areas 16 and 17. After absorbing water and expanding, the insulation 21 can abut against the curtain wall aluminum panels. This can partially seal cracks in the sealant caused by aging, slowing the rate of rainwater infiltration into the curtain wall and buying time for repair personnel. Furthermore, the expansion of the insulation 21 compresses the curtain wall aluminum panels, causing them to bulge and deform. This allows repair personnel to quickly locate the cracks in the sealant by observing the deformation of the curtain wall aluminum panels, improving the timeliness and efficiency of repairs.

[0070] On the other hand, the combination of the isolation plate 13 and the absorbent pad 19 in this embodiment also provides fire protection. When a fire occurs on the building's exterior wall, the isolation plate 13 can effectively block the spread of flames, slowing the spread of the fire and improving the fire resistance of the building curtain wall. It should be noted that in this embodiment, the surface of the first limiting plate 14 is provided with water-permeable holes, so that leaking rainwater can spread along the surface of the isolation plate 13 to the location of the absorbent pad 19.

[0071] As a preferred embodiment, based on the above approach, the edges of the isolation panels 13 that abut the building's exterior wall are further fabricated from a rubber material; and sealant is applied to the edges of the isolation panels 13 that abut the building's exterior wall. This structural arrangement allows the rubber material to exhibit excellent elasticity and sealing properties, enhancing the tightness of the isolation panels 13 against the building's exterior wall. Furthermore, the sealant further enhances the seal between the isolation panels 13 and the building's exterior wall, effectively preventing rainwater from seeping downward and damaging the insulation 21 below, thereby extending the service life of the curtain wall.

[0072] During the specific implementation process, sealant is first applied to the edge of the isolation panel 13 that abuts the building's exterior wall, and then the isolation panel 13 is installed between the building's exterior wall and the curtain wall keel 4. This improves the convenience of applying the sealant and avoids the situation where uneven application of the sealant leads to poor sealing effect.

[0073] As a preferred embodiment, based on the above method, the isolation panels 13 are further arranged at an upward inclination. This structural arrangement further prevents rainwater from seeping downward through the gap between the isolation panels 13 and the building's exterior wall. Furthermore, the inclined isolation panels 13 facilitate rapid drainage of rainwater, preventing accumulation of rainwater on the isolation panels 13, thereby further extending the service life of the curtain wall.

[0074] As a preferred embodiment, based on the above approach, a further gap is provided between the insulation 21 and the exterior wall of the building structure when the insulation 21 is located in the first accommodation area 16. This arrangement creates an air layer between the insulation 21 and the exterior wall of the building structure, thereby improving the thermal insulation performance of the curtain wall.
