Description

Technical Field

[0001] The invention relates to the field of curtain wall decoration, and in particular to an inwardly inclined curved glass curtain wall with an adjustable angle grid and a construction method. Background Art

[0002] In some public buildings, especially large, high-rise ones, streamlined lines, curved surfaces, inverted structures, and other unusual structures are often used to create landmarks, highlight the designer's inspiration, and showcase the uniqueness and aesthetic beauty of the architectural design. This creates a more graceful, curvaceous, and representative building. Due to the large variations in the irregular curves and the unique stress conditions, the deviations caused by torsion between the main structure and the curtain wall keel, which are typically used in glass curtain walls with steel as the main structure, greatly affect the stability and aesthetics of the curtain wall structure, posing a significant safety hazard. How to fully demonstrate the architect's design inspiration, create a landmark building, showcase the morphological aesthetics and decorative effects of the building's exterior wall, and eliminate the deviations caused by torsion between the main structure and the curtain wall keel, has become an urgent problem to be solved.

[0003] Compared with existing conventional structures: Conventional component-type glass curtain walls have a relatively square or circular geometry, which is convenient for construction and force transmission. The entire structure is generally vertically coplanar from top to bottom.

[0004] Compared to existing inward-tilting curtain wall structures, these are generally used in low-rise, small buildings, tending to be square and slightly inward-tilted. The angle (amplitude) of inclination is generally small, and the area involved is relatively small, making large-scale torsion and tilt unlikely. Furthermore, because curved torsion glass curtain walls are subjected to uneven forces, their tension, compression, and shear properties differ from those of conventional curtain wall structures. This can easily lead to loosening, falling off, and deformation at the intersection of the mullions and transoms, particularly when tilted inward, compromising the curtain wall's safety.

[0005] Compared with the stress analysis of existing conventional curtain walls: the stress of ordinary glass curtain walls is generally more uniform and consistent, and vertical stress is adopted, so there will be no tilted stress, uneven force points and keel nodes.

[0006] Compared with the construction difficulty analysis of existing conventional curtain walls: conventional glass curtain walls do not have the characteristics of inward tilt, torsion, and curved surface at the same time; inverted glass curtain walls are generally composed of multiple layers of tempered glass in order to better achieve sound insulation and heat insulation, which inevitably leads to their heavy weight, eccentric force, uneven force, and the force cannot be well transmitted to the supporting structure, resulting in the installed glass easily falling off.

[0007] The processing of special-shaped glass in hyperbolic twisted glass curtain walls is challenging, resulting in low yields and high costs. During construction, challenges often arise, including difficulty coordinating and unifying the curved grids and blocks, complex technical parameters for the individual glass panels, and long processing times. Furthermore, conflicts and inconsistencies arise between the main structural design and the curtain wall. The question is how to fully demonstrate the architect's design inspiration, create a landmark building, and showcase the building's exterior aesthetics and decorative effects. Summary of the Invention

The angle direction formed by the adjustable support piece on the connecting piece is opposite to the angle direction formed by the curtain wall vertical frame and the connecting piece.

[0014] Furthermore, there is an adjustment gap in the adjustable support, and the curtain wall vertical frame is connected to the adjustable support to adjust the angle through the adjustment gap, and an adjustment hole is provided on the adjustable support; the adjustment hole is a long strip structure, and the adjustment hole is axially aligned with the docking bolt hole opened at the upper end of the curtain wall vertical frame and is movably connected through a fastening bolt, and the fastening bolt slides linearly in the adjustment hole.

[0017] Furthermore, the grille connector consists of a rotating shaft and two connecting wing plates, the connecting wing plates are hinged on the side walls of the rotating shaft, and the connecting wing plates are connected to the vertical keel connector of the adjustable angle grille through fastening bolts.

[0018] Furthermore, the inclination angle of the adjustable angle grille is consistent with the inclination angle of the curtain wall mullion, and both the adjustable angle grille and the curtain wall mullion are inwardly inclined structures.

[0019] Furthermore, the main body of the steel structure is composed of a main beam, a secondary beam and an edge beam. The edge beam is installed at both ends of the main beam, and the secondary beam is connected perpendicular to the main beam. The edge beam is connected to the supporting structure connection end plate and the structural connection reinforcement plate of the transfer support by welding, and steel bars are embedded in the main body of the steel structure.

[0020] A construction method for an inwardly inclined curved glass curtain wall with an adjustable angle grille comprises the following steps:

[0021] S1. Construction preparation: Based on the design drawings and design instructions, use 3D modeling software to build a BIM model of the building's internal inclined curved glass curtain wall. Use the BIM model to compare and analyze the steel structure and perform collision detection. Use the Python high-level programming language to unfold the curved glass to a flat surface. The warpage value of each piece of glass is different. Use simulation software to analyze and regularize the glass warpage of the internal inclined curved glass curtain wall.

[0022] S2. Re-survey and measurement of steel structure: A 3D laser scanner was set up to scan the main steel structure to verify its construction accuracy and make error adjustments. By comparing the 3D scan model with the BIM model, the structural errors within the absorbable range of the curtain wall were optimized and adjusted in the BIM model. Structural deviations beyond the absorbable range of the curtain wall were corrected to meet the construction requirements of the curtain wall. Based on the coordinate control points, the coordinate control points of the inward-inclined glass curtain wall were measured and laid out. A total station was used for layout, and the center line was drawn on the ground with an ink fountain. The positions of the points were marked with red paint, and the brackets and curtain wall keel installation position lines were laid out one by one.

[0023] S3. Installation of transfer supports: Before the construction of transfer supports, the fire retardant coating on the surface of the steel beams of the steel structure should be removed. At the same time, the galvanized layer at the connection position between the transfer supports and the edge beams of the steel structure needs to be polished and removed in advance. Use an aerial crane to deliver the transfer supports to the location where they need to be installed, and manually move them to the location where they need to be installed. After re-measurement of the installation position, adjust the installation angle and position, and verify that they are correct, weld the transfer support structure connection reinforcement plate to the edge beam of the welded main steel structure. After the reinforcement plate is welded, weld the stiffeners on both sides of the transfer supports.

[0024] S4. Curtain wall keel installation: When installing the steel inserts on the top of the transfer support, the installation position should be re-measured. Only after the re-measured position is accurate can the vertical frame steel inserts be installed to provide a support foundation for the installation of the curtain wall vertical frame and to adjust the error and expansion deformation of the curtain wall vertical frame. Then, the vertical frame should be straightened and the installation position adjusted. The bottom of the curtain wall vertical frame should be preliminarily fixed to the steel inserts on the top of the transfer support by fastening bolts. It should be preliminarily fixed to the top steel bracket using the top transfer support and the adjustable support pre-installed on the curtain wall vertical frame. Then, the final position and angle of the vertical frame should be adjusted. After adjusting and correcting the vertical frame installation position, pay special attention to the error adjustment caused by the change of the curved surface and the structural deviation. After confirming that it meets the installation requirements, the reverse support at the top of the vertical frame should be welded to the transfer support to achieve effective fixation of the single vertical frame. After the vertical frame installation is completed, the horizontal aluminum frame steel inserts should be installed first according to the installation position of the curtain wall horizontal frame design, and then the curtain wall horizontal frame should be installed. The single-piece internal inclined glass installation and fixing frame is formed by combining the horizontal and vertical parts of the curtain wall.

[0025] S5. Glass installation: According to the glass number processed in advance at the factory and sent to the construction site, a crane and a glass suction cup car are used to transport the glass to the corresponding installation position. After adjusting the installation angle, the installer first adjusts the error using glass spacers, then preliminarily fixes the glass around the edges, and then uses self-tapping bolts to gradually fix the stainless steel pressure blocks to the entire single glass;

[0026] S6. After the glass and pressure blocks are installed, install the buckle cover. During the installation process, protect the fluorocarbon coating on the buckle cover to avoid affecting the final decorative effect. After the installation is completed, tear off the protective layer on the buckle cover; apply glue to close the curtain wall. Before applying glue, clean any impurities or dust on the glass surface. Maintain a certain spacing and apply glue evenly to ensure that the glue is full and even, without bubbles and other quality defects. Ensure that the seam width is consistent. When applying glue to different materials, use masking tape to protect them first to avoid contamination. Choose professional and skilled workers to apply glue.

[0027] S7. Installation of grille connectors: After measuring and positioning the control axis, make detailed measurements and confirm the location where the grille adapter needs to be installed. In order to ensure the overall effect and aesthetics of the grille installation, the grille connector needs to be kept in a straight line vertically from the bottom of the inner-inclined glass curtain wall to the top of the curtain wall during installation. The adapter is located at the center of the sealing plate at the end of the adapter support. The vertical error does not exceed ≤2mm, ensuring that the horizontal and vertical directions of the grille connector are on a straight installation segment; after confirming that the position is correct, connect it to the inner-inclined sealing plate of the adapter support through full welding to provide an installation support foundation for the grille. Each grille requires no less than 2 grille adapters when installing, and the angle of a single grille can be adjusted through this adjustable angle connector; after the grille adapter is installed, it is necessary to conduct pull-out tests and weld flaw detection, etc. On the basis of passing the self-inspection, entrust a third party to conduct pull-out testing. After passing the third-party quality inspection, the weld is subjected to rust-proof treatment. Only after the rust-proof treatment is qualified can the next construction process be carried out;

[0028] S8. Grille installation: After completing the relevant installation steps of the inward-tilted glass curtain wall and after being inspected and verified as qualified by the responsible parties, the inward-tilted adjustable angle grille is installed; the grille is transported to the bottom of the building where it needs to be hoisted by a forklift, and then hoisted to the required installation position by an overhead crane. The grille is manually moved to the required installation position. During the movement, pay attention to protecting the finished glass curtain wall to avoid damage; during installation, first fix the grille connection accessories reserved at the bottom of the grille to the protruding adapter of the bottom adapter support, and then fix the adapter accessories reserved at the top of the grille to the adapter reserved on the top steel bracket, and then perform preliminary fixation with the fixing nuts on the adapter;

[0029] S9. Grille Closure: Due to the length limitations of individual grilles, single-row grilles are typically constructed from multiple pieces. After installation, the vertical joints should be sealed with glue. Before applying glue, any impurities or dust on the grille surface should be cleaned. Glue the grille joints with a consistent spacing and even pressure to ensure full, even application without air bubbles or other quality defects. The glue seams should also be consistent in width.

[0030] Based on the above technical solution, the present invention can produce the following beneficial effects:

[0031] The present invention provides an inward-inclined curved glass curtain wall with an adjustable angle grille and a construction method. The present invention enables the inclined vertical frame to be adjusted in inclination during installation by means of a steel insert provided on a transfer support and an adjustable support provided in the opposite direction; and the inward-inclined curtain wall is supported under the action of the transfer support, and the stress is dispersed to improve the bearing capacity of the inward-inclined curtain wall. The inward-inclined curved glass curtain wall with an adjustable angle grille and the adjustable angle decorative grille help to show the rhythm, light and shadow, hierarchy and changing architectural features of the building, thereby showing a more beautiful, more prominent curve and more representative building. The inverted curved surface changing curtain wall and the angle-adjustable adjustable angle grille are used to create a unique and dynamic aesthetic of the building, laying a solid foundation for building landmark buildings and creating the possibility of creating buildings with special-shaped curves, twists, inverted and the like.

[0064] A construction method for an inwardly inclined curved glass curtain wall with an adjustable angle grille comprises the following steps:

[0065] S1. Construction preparation: Based on the design drawings and design instructions, use 3D modeling software to build a BIM model of the building's internal inclined curved glass curtain wall. Use the BIM model to compare and analyze the steel structure and perform collision detection. Use the Python high-level programming language to unfold the curved glass to a flat surface. The warpage value of each piece of glass is different. Use simulation software to analyze and regularize the glass warpage of the internal inclined curved glass curtain wall.

[0066] S2. Re-survey and measurement of steel structure: A 3D laser scanner was set up to scan the main steel structure to verify its construction accuracy and make error adjustments. By comparing the 3D scan model with the BIM model, the structural errors within the absorbable range of the curtain wall were optimized and adjusted in the BIM model. Structural deviations beyond the absorbable range of the curtain wall were corrected to meet the construction requirements of the curtain wall. Based on the coordinate control points, the coordinate control points of the inward-inclined glass curtain wall were measured and laid out. A total station was used for layout, and the center line was drawn on the ground with an ink fountain. The positions of the points were marked with red paint, and the brackets and curtain wall keel installation position lines were laid out one by one.

[0067] S3. Installation of the transfer support 4: Before the construction of the transfer support 4, the fire retardant paint on the surface of the steel beam of the steel structure should be removed. At the same time, the galvanized layer at the connection position between the transfer support 4 and the edge beam 11 of the steel structure needs to be polished and removed in advance. Use an aerial crane to deliver the transfer support 4 to the required installation position, and manually move it to the required installation position. After re-measurement of the installation position, adjust the installation angle and position and verify that they are correct, weld the structural connection reinforcement plate of the transfer support 4 to the edge beam of the welded main steel structure. After the reinforcement plate is welded, weld the stiffening plates on both sides of the transfer support 4.

[0068] S4. Installation of curtain wall keels: When installing the steel insert 7 on the top of the transfer support 4, the installation position should be re-measured. Only after the re-measured position is accurate can the vertical frame steel insert 7 be installed to provide a support foundation for the installation of the curtain wall vertical frame 1 and to adjust the error and expansion deformation of the curtain wall vertical frame 1. Then straighten the vertical frame and adjust the installation position.

Construction Preparation: Based on the design drawings and design specifications, use 3D modeling software to create a BIM model of the building's internal inclined curved glass curtain wall. Use the BIM model to conduct comparative analysis and collision detection with the main steel structure. Use the Python high-level programming language to unfold the curved glass to a flat surface. Since the warpage value of each piece of glass is different, use simulation software to analyze and regularize the glass warpage of the internal inclined curved glass curtain wall. S2. Re-survey and measurement of steel structure: Set up a 3D laser scanner to scan the main steel structure to verify the construction accuracy of the main steel structure and make error adjustments. Compare the 3D scanning model with the BIM model to optimize and adjust the structural errors within the absorbable range of the curtain wall. Make structural corrections to the structural deviations beyond the absorbable range of the curtain wall to meet the construction requirements of the curtain wall. According to the coordinate control points, measure and lay out the coordinate control points of the inner tilted glass curtain wall. Use a total station to coordinate the layout. Use an ink fountain to pop out the center line on the ground. Use red paint to mark the position of the point. Lay out the adapter support (4) and the curtain wall keel installation position line one by one. S3. Installation of the transfer support (4): Before the construction of the transfer support (4), the fire retardant coating on the surface of the steel beam of the steel structure should be removed. At the same time, the galvanized layer at the connection position between the transfer support (4) and the edge beam (11) of the steel structure should be polished and removed in advance. The transfer support (4) should be sent to the location where it needs to be installed by a high-altitude crane, and manually moved to the location where it needs to be installed. The installation position should be re-measured. After the installation angle and position are adjusted and verified, the transfer support (4) structural connection reinforcement plate should be welded to the edge beam of the main steel structure. After the reinforcement plate is welded, the reinforcement plates on both sides of the transfer support (4) should be welded. S4. Installation of curtain wall keels: When installing the steel insert (7) on the top of the transfer support (4), the installation position should be re-measured. Only after the re-measured position is accurate can the vertical frame steel insert (7) be installed to provide a support base for the installation of the curtain wall vertical frame (1) and to adjust the error and expansion deformation of the curtain wall vertical frame (1). Then, the vertical frame is straightened and the installation position is adjusted. The bottom of the curtain wall vertical frame (1) is preliminarily fixed to the steel insert (7) on the top of the transfer support (4) by fastening bolts (16). Then, the adjustable support pre-installed on the top transfer support (4) and the curtain wall vertical frame (1) is used to adjust the vertical frame (7). The support member (8) is initially fixed on the top transfer support member (4), and then the final position and angle of the vertical frame are adjusted; after adjusting and correcting the installation position of the vertical frame, special attention is paid to the error adjustment caused by the change of the curved surface and the structural deviation; after confirming that it meets the installation requirements, the adjustable support member (8) is welded on the transfer support member (4) at the top of the vertical frame to achieve effective fixation of the single vertical frame; after the vertical frame is installed, the horizontal aluminum frame steel insert is installed first according to the installation position of the curtain wall horizontal frame design, and then the curtain wall horizontal frame is installed, and a single piece of internal tilted glass installation fixing frame is formed by combining the horizontal and vertical parts of the curtain wall; S5. Glass installation: According to the glass number processed in advance at the factory and delivered to the construction site, a crane and a glass suction cup car are used to move the glass to the corresponding installation position. After adjusting the installation angle, the installer first adjusts the error using glass spacers, then preliminarily fixes the glass around the edges, and then uses self-tapping bolts to gradually fix the stainless steel pressure blocks to the entire single glass; S6. After the glass and pressure blocks are installed, the buckle cover is installed. During the installation process, the fluorocarbon coating on the surface of the buckle cover is protected to avoid affecting the final decorative effect. After the installation is completed, the protective layer on the buckle cover is torn off; the curtain wall is sealed with glue. Before gluing, impurities or dust on the glass surface should be cleaned. When gluing, keep a certain distance and apply the glue evenly to ensure that the glue is full and uniform without air bubbles and quality defects. Ensure that the seam width is consistent. When gluing different materials, masking tape should be used for protection first to avoid contamination. Choose professional and skilled workers to do the gluing. S7. Installation of grille connectors: After measuring and positioning the control axis, first confirm the location where the grille connectors need to be installed. To ensure the overall effect and aesthetics of the grille installation, the grille connectors must be installed in a straight line from the bottom of the inward-sloping glass curtain wall to the top of the curtain wall. The grille connectors must be located at the center of the adapter support and adapter end plate, with a vertical error of no more than 2mm. Ensure that the grille connectors are on a straight installation line both horizontally and vertically. After confirming the correct position, it is connected to the transfer end plate of the transfer support through full welding to provide a support foundation for the installation of the grille. Each grille is installed with no less than 2 grille connectors. At the same time, the grille connectors can be used to adjust the angle of a single grille. After the grille connectors are installed, they need to undergo a pull-out test and weld flaw detection. On the basis of passing the self-inspection, a third party is commissioned to conduct a pull-out test. After passing the third-party quality inspection, the welds are subjected to rust-proof treatment. Only after the rust-proof treatment is qualified can the next process be carried out. S8. Grille installation: After completing the relevant installation steps of the inward-tilted glass curtain wall and after inspection and verification by the responsible parties, the inward-tilted adjustable angle grille is installed. The grille is transported to the bottom of the building where it needs to be hoisted by a forklift, and then hoisted to the installation height by an overhead crane. The grille is manually moved to the required installation location. During the movement, care should be taken to protect the finished glass curtain wall to avoid damage. During installation, first fix the grille connection fittings reserved at the bottom of the grille to the grille connection piece protruding from the bottom transfer support (4), then fix the grille connection fittings reserved at the top of the grille to the grille connection piece reserved at the top transfer support (4), and then perform preliminary fixation by fixing the nuts on the grille connection piece; S9. Grille closing: Because a single grille is limited by length, single-row grilles on site are made up of multiple grilles. After the single-row grilles are installed, the joints at the vertical joint positions of the single-row grilles should be sealed with glue. Before gluing, impurities or dust on the surface of the grille should be cleaned. The gluing of the grille joints should be kept at a certain distance and with uniform force to ensure that the glue is full, uniform, and free of bubble quality defects, and the width of the glue seams must be consistent.
