[0036] In one embodiment, in step S3, the specific steps of construction preparation are as follows:

[0037] According to the plan, make preparations for on-site construction, mainly including the deployment of operators for each system of the composite curtain wall, mechanical measures, material conditions, as well as environmental protection and safety measures, to provide a foundation for the next step of on-site construction.

[0038] In one embodiment, in step S4, the specific contents of the civil engineering handover are as follows:

[0039] The general contractor's project management personnel shall organize the civil engineering and curtain wall professional management, technical personnel, and operating personnel to verify the completion status of the civil engineering division to check whether there are any omissions in the construction items and whether there are any quality defects in the completed processes (such as the handover of axis lines, outdoor elevations, lightning protection and grounding locations, measurement control points, etc.), and the person in charge of each professional unit shall sign a process handover confirmation form. Any corresponding problems found shall be rectified within a limited time.

[0040] In one embodiment, in step S5, the specific contents of the error check of the civil engineering structure 25 are as follows:

[0041] In order to ensure the overall effect of the facade, 3D scanning technology is used to scan the completed main body, generate a point cloud model, and combine it with the curtain wall BIM model to eliminate construction errors to the greatest extent possible from the source.

[0042] In one embodiment, in step S6, the specific steps of measuring and setting out are as follows:

[0043] S61. First, determine the installation elevation of the first floor buried slab based on the elevation control points handed over by the civil engineering;

[0044] S62. Using the control elevation of the first-floor rear embedded slab as the base point, calculate the longitudinal spacing along the column to the top rear embedded slab (combined with the design drawing elevation and the building structure elevation);

[0045] S63. The spacing of the horizontal rear embedded slabs shall be calculated along the beam using the axis as the base point in the structural design drawings. The spacing shall be calculated from the central axis of the building to both sides, or from the axis of one side as the reference line to the other side.

[0046] S64, performing line drawing according to the determined points;

[0047] S65. After the longitudinal and transverse measurements are completed, re-measurement is carried out to ensure that the accuracy meets the allowable deviation range before proceeding to the next construction process.

[0048] In one embodiment, in step S7, the installation process of the post-embedded component 24 is as follows:

[0049] According to the measurement and layout results, before installing the rear embedded plate, clean the hole first, clean the dust in the hole, and then install the post-cut mechanical anchor bolt 23;

[0050] Install the back-embedded parts 24. During the installation process, strictly control the verticality and horizontality of the back-embedded parts 24. The installation deviation shall not exceed the allowable deviation range.

[0051] The model, specification and number of bolts of each post-embedded part 24 must meet the design requirements, and each anchor bolt must be tightened without any looseness.

[0052] In one embodiment, in step S8, the specific steps of the pull-out test of the post-embedded part 24 are as follows:

[0053] The testing unit shall conduct on-site pull-out tests and the testing organization shall issue a qualified test report. The next construction process shall not be carried out until the test is qualified.

[0054] In one embodiment, in step S9, the specific contents of the connector installation are as follows:

[0055] S91. Install channel steel connectors according to the center line and grid lines drawn by the layout. Spot weld first, and then perform full welding and repair welding after the entire layer has been corrected. The welds must be full and dense, and no welding defects such as slag inclusions, pores, and cold welds should be present.

[0056] S92. After the welding is completed and the team self-inspects and passes, the project's dedicated quality inspector will inspect and confirm that there are no quality defects. After that, the supervisor and Party A will be notified to conduct on-site welding quality inspection and acceptance. Quality control shall be strictly carried out in accordance with the "three inspections" system.

[0057] S93. After acceptance, perform anti-rust treatment on welds and connectors and apply three coats of anti-rust paint.

[0058] In one embodiment, in step S10, the specific steps of installing the keel are:

[0059] The curtain wall aluminum alloy columns 3 are bolted to the channel steel connectors using stainless steel bolt assemblies 6. The curtain wall aluminum alloy cross frame 2 is installed and securely connected to the curtain wall aluminum alloy columns 3 using stainless steel spring pins 11. The upper and lower curtain wall aluminum alloy columns 3 are connected by aluminum alloy inserts. Installation direction for the same floor is from bottom to top. At a certain height, inspection, adjustment, calibration, and fastening are carried out to ensure that the quality meets the design and construction quality acceptance standards.

[0060] Installation quality requirements: Install the vertical frame 18 first, and pre-install the vertical frame 18 and the connecting parts first; adjust the height deviation of the vertical frame 18 axis and elevation position to no more than 2mm, the inside and outside deviation of the axis is no more than 2mm, the left and right deviation is no more than 3mm, the installation deviation of two adjacent verticals is no more than 1mm, the maximum vertical deviation on the same floor is no more than 5mm, and the height deviation is no more than 1mm.

[0061] In one embodiment, in step S11, the curtain wall fire protection, lightning protection, and thermal insulation system are installed in the following specific steps:

[0062] The gaps between the glass curtain wall and the inter-story floor, and between the curtain wall and the transverse partition wall, are separated by fireproof rock wool 21, with a laying thickness of not less than 200mm. After the rock wool is laid, it is supported by hot-dip galvanized steel plates 20, and the joint gaps are effectively sealed with fireproof sealant to ensure a fully enclosed isolation zone with the floor or wall.

[0063] The main structure lightning protection system is connected by welding and painted with anti-rust paint, with an overlap length of at least 100mm and full triangular welding. The lightning protection steel bars are hot-dip galvanized and painted with anti-rust paint after welding. Lightning protection belts should be installed in areas susceptible to lightning strikes, such as corners, and the curtain wall lightning protection system should be reliably connected to the top and bottom of the main structure. Before installing the lightning protection wire, the surface coating of the aluminum profile must be removed to ensure that the welds are full and firm, and no weld leaks or arbitrary changes in node positions are allowed.

[0064] The thermal insulation rock wool 29 is fixed to the rear side of the aluminum single plate 28 by rock wool nails 30 .

[0065] In one embodiment, in step S12, the specific steps of the hidden acceptance are as follows:

[0066] After the above steps are completed, the team and project management personnel will conduct self-inspection and make corrections, and then the supervisor will jointly organize the hidden acceptance inspection with Party A;

[0067] The acceptance contents include 24 post-embedded parts, firm connection of keels, lightning protection grounding and devices, etc.; the hidden acceptance raw material incoming inspection report and re-inspection report are complete, and the pull-out test report is complete.

[0068] In one embodiment, in step S13, the specific steps of installing the glass panel are as follows:

[0069] Connection method: Horizontally, the glass frame is bonded to the glass, and the glass frame and the beam are fixed at a fixed distance using stainless steel bolts through the decorative cover plate 8; vertically, the glass is fixed with a full-length aluminum alloy pressure block, and the pressure block and the column are fixed at a fixed distance using self-drilling screws.

[0070] When the glass area is less than 3㎡, it can be installed manually; if it exceeds 3㎡, mechanical assistance is required, such as a vacuum suction cup; vertical transportation of glass requires the cooperation of a tower crane for lifting. During installation, a certain gap should be maintained between the glass and the component, and a positioning pad with a width consistent with the groove and a length of at least 100mm should be placed at the bottom.

[0071] In one embodiment, in step S14, the specific steps for installing the aluminum composite panel and the aluminum single panel 28 are as follows:

[0072] The aluminum veneer 28, aluminum composite panel and aluminum auxiliary frame are connected by aluminum nails, and the aluminum auxiliary frame is fixed to the curtain wall aluminum alloy horizontal frame 2 by self-drilling screws;

[0073] Installation steps: After each aluminum composite panel and aluminum single panel 28 is cut, corner-cut, folded, and corner pieces, reinforcement ribs and frame are installed in the assembly plant, labels are affixed to each panel.

[0074] Install it on the aluminum alloy frame with self-drilling nails according to the grid diagram, and adjust the left and right positions of the panels from top to bottom to ensure the flatness and joint spacing of the two adjacent panels; after overall correction, fill the gaps between the panels with foam strips and apply weather-resistant sealant.

[0075] In one embodiment, in step S15, the decorative grille installation step:

[0076] S151. After completing the relevant construction processes of the glass curtain wall, install the glass curtain wall transverse keels and the glass curtain wall wing-shaped decorative grille structure (which serves as both glass fixing fixtures and wing-shaped grille installation supports);

[0077] The horizontal frame 17 at the tail end of the decorative grille is bolted and fixed to the decorative cover plate 8 and the curtain wall aluminum alloy horizontal frame 2 by using a stainless steel bolt assembly 6 after the glass is installed; the integrated decorative cover plate 8 and the curtain wall aluminum alloy horizontal frame 2 together serve as the horizontal force-bearing structure of the single-piece wing-type grille; the decorative cover plate 8 serves as both a fixing member of the curtain wall glass 1 and a horizontal support member for the installation of the wing-type grille. The force is distributed by the decorative cover plate 8 of the same length as the grille, thereby ensuring the stability of the distributed force of the horizontal frame 17.

[0078] S152. The vertical skeleton 18 on the side of the decorative grille is positioned in sections using a theodolite. After the left and right stainless steel cantilevers 10 of the grille are leveled to the same height, the bottom plate of the stainless steel cantilevers 10 at the tail end is locked and fixed in the slot of the curtain wall aluminum alloy column 3 using internal angle screws. The horizontal and vertical skeletons 18 of the wing-type decorative grille structure are easy to install. The components are produced in units by the manufacturer. The prefabricated construction is conducive to ensuring the construction period. At the same time, it avoids the risk of deformation and falling off of the grille due to excessive wind pressure and load.

[0079] Four stainless steel spring latches 11 are staggered through the stainless steel pick 10 and pinned into the dedicated holes on the side of the decorative grille. After the left and right grilles are uniformly leveled, the ends are plugged in and fixed with aluminum fixings. The staggered installation of the latches and the end plug-in fixation help ensure the stability of the wing-style grille. The uniform leveling reduces the error control of the overall straightness of the wing-style grille.

[0080] S153. Finally, insert the integrated slot on the aluminum alloy wing grille into the decorative cover 8, insert the locking screws on the pick, and secure the grille with self-tapping screws to complete the single-piece installation.

[0081] S154. Repeat the above process until all glass curtain wall wing-shaped decorative grille structures are installed; finally, install the integrated lighting engineering lamps.

[0082] S155. After installation, construction workers should take protective measures on the installed glass curtain wall wing-type decorative grille structure and cover the easily contaminated parts with plastic film or other materials for protection.

[0083] The LED light strip is fixed in the slot structure by the screws at the tail of the base. The wiring circuit is led into the electrical box through the opening of the internal structure of the wing grille. The LED light strip adopts the "buried closing" method to ensure the consistent and beautiful overall color tone of the wing-style decorative grille. At the same time, the assembled full-length linear light strip presents a richer lighting effect for the glass curtain wall structure.

[0084] Drainage is achieved through the upper and lower milling holes in the wing grille lamp slots, and no weather-resistant glue is applied between adjacent grille joints or milling holes. On the one hand, the drainage structure promotes drainage efficiency through the structural slope of the grille itself, and on the other hand, no weather-resistant glue is applied between adjacent grille joints or milling holes, which provides a secondary guarantee for drainage efficiency and effectively prevents wire short circuits caused by water accumulation in the lamp trough.

[0085] In one embodiment, in step S16, the specific steps of dust removal and glue application are as follows:

[0086] S161. Before gluing, clean up any impurities or dust on the surface;

[0087] S162. Check whether the color of the glue is consistent with the design requirements;

[0088] S163. Gluing operations shall not be carried out in rainy weather, gusts of wind above level 5, or in summer weather accompanied by sandstorms;

[0089] S164, keep a certain distance between the glue and apply even force to ensure that the glue is full, even, and free of bubbles and other quality defects; ensure that the seam width is consistent;

[0090] S165. When gluing the wing grille and glass curtain wall aluminum alloy, masking tape should be used to protect them first to avoid contamination.

[0091] S166. For gluing, select professional and skilled workers to carry out the gluing.

[0092] The beneficial effects of the present invention are as follows:

[0093] 1. A composite curtain wall system with wing-shaped decorative grilles and its construction method effectively solve the problems of precise and rapid construction and high-quality adjustment of each unit module of the composite curtain wall in decoration projects with tight construction schedules. All components are fully assembled and installed, reducing on-site secondary processing procedures, facilitating construction, and improving the construction efficiency of decoration, lighting, and drainage projects. At the same time, it also avoids secondary damage to various system components at the construction site and reduces the loss rate.

[0094] 2. The wing-shaped decorative grille has an integrated functional mold, which optimizes the grille's own weight; the hidden stainless steel connector structure and the embedded integrated light trough structure ensure the continuity of the grille's appearance and the uniformity of the building's curtain wall appearance; the stainless steel cantilever and the sliding installation structure connected to the aluminum alloy column slot, the spring pin staggered installation and the end aluminum fixings doubly guarantee the high quality and stability of the structural connection system, and reduce the error control of the overall wing-shaped straightness of the decorative grille assembly.

[0142] In order to ensure the overall effect of the facade, 3D scanning technology is used to scan the completed main body, generate a point cloud model, and combine it with the curtain wall BIM model to eliminate construction errors to the greatest extent possible from the source.

[0143] In step S6, the specific steps of measuring and setting out are as follows:

[0144] S61. First, determine the installation elevation of the first floor buried slab based on the elevation control points handed over by the civil engineering;

[0145] S62. Using the control elevation of the first-floor rear embedded slab as the base point, calculate the longitudinal spacing along the column to the top rear embedded slab (combined with the design drawing elevation and the building structure elevation);

[0146] S63. The spacing of the horizontal rear embedded slabs shall be calculated along the beam using the axis as the base point in the structural design drawings. The spacing shall be calculated from the central axis of the building to both sides, or from the axis of one side as the reference line to the other side.

[0147] S64, performing line drawing according to the determined points;

[0148] S65. After the longitudinal and transverse measurements are completed, re-measurement is carried out to ensure that the accuracy meets the allowable deviation range before proceeding to the next construction process.

[0149] In step S7, the installation process of the post-embedded part 24 is as follows:

[0150] According to the measurement and layout results, before installing the rear embedded plate, clean the hole first, clean the dust in the hole, and then install the post-cut mechanical anchor bolt 23;

[0151] Install the back-embedded parts 24. During the installation process, strictly control the verticality and horizontality of the back-embedded parts 24. The installation deviation shall not exceed the allowable deviation range.

[0152] The model, specification and number of bolts of each post-embedded part 24 must meet the design requirements, and each anchor bolt must be tightened without any looseness.

[0153] In step S8, the specific steps of the pull-out test of the post-embedded part 24 are as follows:

[0154] The testing unit shall conduct on-site pull-out tests and the testing organization shall issue a qualified test report. The next construction process shall not be carried out until the test is qualified.

[0155] In step S9, the specific contents of the connector installation are as follows:

[0156] S91. Install channel steel connectors according to the center line and grid lines drawn by the layout. Spot weld first, and then perform full welding and repair welding after the entire layer has been corrected. The welds must be full and dense, and no welding defects such as slag inclusions, pores, and cold welds should be present.

[0157] S92. After the welding is completed and the team self-inspects and passes, the project's dedicated quality inspector will inspect and confirm that there are no quality defects. After that, the supervisor and Party A will be notified to conduct on-site welding quality inspection and acceptance. Quality control shall be strictly carried out in accordance with the "three inspections" system.

[0158] S93. After acceptance, perform anti-rust treatment on welds and connectors and apply three coats of anti-rust paint.

[0159] In step S10, the specific steps of keel installation are:

[0160] The curtain wall aluminum alloy columns 3 are bolted to the channel steel connectors using stainless steel bolt assemblies 6. The curtain wall aluminum alloy cross frame 2 is installed and securely connected to the curtain wall aluminum alloy columns 3 using stainless steel spring pins 11. The upper and lower curtain wall aluminum alloy columns 3 are connected by aluminum alloy inserts. Installation direction for the same floor is from bottom to top. At a certain height, inspection, adjustment, calibration, and fastening are carried out to ensure that the quality meets the design and construction quality acceptance standards.

[0161] Installation quality requirements: Install the vertical frame 18 first, and pre-install the vertical frame 18 and the connecting parts first; adjust the height deviation of the vertical frame 18 axis and elevation position to no more than 2mm, the inside and outside deviation of the axis is no more than 2mm, the left and right deviation is no more than 3mm, the installation deviation of two adjacent verticals is no more than 1mm, the maximum vertical deviation on the same floor is no more than 5mm, and the height deviation is no more than 1mm.

[0162] In step S11, the specific steps for installing the curtain wall fire protection, lightning protection, and thermal insulation systems are as follows:

[0163] The gaps between the glass curtain wall and the inter-story floor, and between the curtain wall and the transverse partition wall, are separated by fireproof rock wool 21, with a laying thickness of not less than 200mm. After the rock wool is laid, it is supported by hot-dip galvanized steel plates 20, and the joint gaps are effectively sealed with fireproof sealant to ensure a fully enclosed isolation zone with the floor or wall.

[0164] The main structure lightning protection system is connected by welding and painted with anti-rust paint, with an overlap length of at least 100mm and full triangular welding. The lightning protection steel bars are hot-dip galvanized and painted with anti-rust paint after welding. Lightning protection belts should be installed in areas susceptible to lightning strikes, such as corners, and the curtain wall lightning protection system should be reliably connected to the top and bottom of the main structure. Before installing the lightning protection wire, the surface coating of the aluminum profile must be removed to ensure that the welds are full and firm, and no weld leaks or arbitrary changes in node positions are allowed.

[0165] The thermal insulation rock wool 29 is fixed to the rear side of the aluminum single plate 28 by rock wool nails 30 .

[0166] In step S12, the specific steps of concealed acceptance are as follows:

[0167] After the above steps are completed, the team and project management personnel will conduct self-inspection and make corrections, and then the supervisor will jointly organize the hidden acceptance inspection with Party A;

[0168] The acceptance contents include 24 post-embedded parts, firm connection of keels, lightning protection grounding and devices, etc.; the hidden acceptance raw material incoming inspection report and re-inspection report are complete, and the pull-out test report is complete.

[0169] In step S13, the specific steps of installing the glass panels are as follows:

[0170] Connection method: Horizontally, the glass frame is bonded to the glass, and the glass frame and the beam are fixed at a fixed distance using stainless steel bolts through the decorative cover plate 8; vertically, the glass is fixed with a full-length aluminum alloy pressure block, and the pressure block and the column are fixed at a fixed distance using self-drilling screws.

[0171] When the glass area is less than 3㎡, it can be installed manually; if it exceeds 3㎡, mechanical assistance is required, such as a vacuum suction cup; vertical transportation of glass requires the cooperation of a tower crane for lifting. During installation, a certain gap should be maintained between the glass and the component, and a positioning pad with a width consistent with the groove and a length of at least 100mm should be placed at the bottom.

[0172] In step S14, the specific steps of installing the aluminum composite panel and the aluminum single panel 28 are as follows:

[0173] The aluminum veneer 28, aluminum composite panel and aluminum auxiliary frame are connected by aluminum nails, and the aluminum auxiliary frame is fixed to the curtain wall aluminum alloy horizontal frame 2 by self-drilling screws;

[0174] Installation steps: After each aluminum composite panel and aluminum single panel 28 is cut, corner-cut, folded, and corner pieces, reinforcement ribs and frame are installed in the assembly plant, labels are affixed to each panel.

[0175] Install it on the aluminum alloy frame with self-drilling nails according to the grid diagram, and adjust the left and right positions of the panels from top to bottom to ensure the flatness and joint spacing of the two adjacent panels; after overall correction, fill the gaps between the panels with foam strips and apply weather-resistant sealant.

[0176] In step S15, the decorative grille installation steps are:

[0177] S151. After completing the relevant construction processes of the glass curtain wall, install the glass curtain wall transverse keels and the glass curtain wall wing-shaped decorative grille structure (which serves as both glass fixing fixtures and wing-shaped grille installation supports);

[0178] The horizontal frame 17 at the tail end of the decorative grille is bolted and fixed to the decorative cover plate 8 and the curtain wall aluminum alloy horizontal frame 2 by using a stainless steel bolt assembly 6 after the glass is installed; the integrated decorative cover plate 8 and the curtain wall aluminum alloy horizontal frame 2 together serve as the horizontal force-bearing structure of the single-piece wing-type grille; the decorative cover plate 8 serves as both a fixing member of the curtain wall glass 1 and a horizontal support member for the installation of the wing-type grille. The force is distributed by the decorative cover plate 8 of the same length as the grille, thereby ensuring the stability of the distributed force of the horizontal frame 17.

[0179] S152. The vertical skeleton 18 on the side of the decorative grille is positioned in sections using a theodolite. After the left and right stainless steel cantilevers 10 of the grille are leveled to the same height, the bottom plate of the stainless steel cantilevers 10 at the tail end is locked and fixed in the slot of the curtain wall aluminum alloy column 3 using internal angle screws. The horizontal and vertical skeletons 18 of the wing-type decorative grille structure are easy to install. The components are produced in units by the manufacturer. The prefabricated construction is conducive to ensuring the construction period. At the same time, it avoids the risk of deformation and falling off of the grille due to excessive wind pressure and load.

[0180] Four stainless steel spring latches 11 are staggered through the stainless steel pick 10 and pinned into the dedicated holes on the side of the decorative grille. After the left and right grilles are uniformly leveled, the ends are plugged in and fixed with aluminum fixings. The staggered installation of the latches and the end plug-in fixation help ensure the stability of the wing-style grille. The uniform leveling reduces the error control of the overall straightness of the wing-style grille.

[0181] S153. Finally, insert the integrated slot on the aluminum alloy wing grille into the decorative cover 8, insert the locking screws on the pick, and secure the grille with self-tapping screws to complete the single-piece installation.

[0182] S154. Repeat the above process until all glass curtain wall wing-shaped decorative grille structures are installed; finally, install the integrated lighting engineering lamps.

[0183] S155. After installation, construction workers should take protective measures on the installed glass curtain wall wing-type decorative grille structure and cover the easily contaminated parts with plastic film or other materials for protection.

[0184] The LED light strip is fixed in the slot structure by the screws at the tail of the base. The wiring circuit is led into the electrical box through the opening of the internal structure of the wing grille. The LED light strip adopts the "buried closing" method to ensure the consistent and beautiful overall color tone of the wing-style decorative grille. At the same time, the assembled full-length linear light strip presents a richer lighting effect for the glass curtain wall structure.

[0185] Drainage is achieved through the upper and lower milling holes in the wing grille lamp slots, and no weather-resistant glue is applied between adjacent grille joints or milling holes. On the one hand, the drainage structure promotes drainage efficiency through the structural slope of the grille itself, and on the other hand, no weather-resistant glue is applied between adjacent grille joints or milling holes, which provides a secondary guarantee for drainage efficiency and effectively prevents wire short circuits caused by water accumulation in the lamp trough.

[0186] In step S16, the specific steps of dust removal and glue application are as follows:

[0187] S161. Before gluing, clean the surface impurities and dust.

[0188] S162. Check whether the color of the glue is consistent with the design requirements;

[0189] S163. Gluing operations shall not be carried out in rainy weather, gusts of wind above level 5, or in summer weather accompanied by sandstorms;

[0190] S164, keep a certain distance between the glue and apply even force to ensure that the glue is full, even, and free of bubbles and other quality defects; ensure that the seam width is consistent;

[0191] S165. When gluing the wing grille and glass curtain wall aluminum alloy, masking tape should be used to protect them first to avoid contamination.

[0192] S166. For gluing, select professional and skilled workers to carry out the gluing.

[0193] Example 3

[0194] like Figures 2 to 4 As shown, this embodiment provides a glass curtain wall wing-type decorative grille structure, including a multi-layer grille assembly installed on the outside of the glass curtain wall, each layer of the grille assembly includes a plurality of grille units 16 spliced ​​in sequence, and adjacent two grille units 16 are locked by a locking assembly. Each grille unit 16 is provided with a decorative light trough 9 for installing a decorative light, each decorative light trough 9 is provided with a drainage channel, and each decorative light trough 9 is installed with a lighting assembly.

[0195] Each grille unit 16 includes an integrally formed grille main structure 5, a transverse frame 17 installed on the inner side of the grille main structure 5, and vertical frames 18 arranged on the left and right sides of the grille main structure 5; the transverse frame 17 is installed horizontally on the glass curtain wall, and the vertical frame 18 is installed longitudinally on the glass curtain wall. The inner side of the grille main structure 5 and the left and right ends of the grille main structure 5 are respectively installed on the transverse frame 17 and the vertical frame 18.

[0196] Specifically, the horizontal and vertical frames 18 of the grille units 16 are easy to install. The components are manufactured in units by the manufacturer. The assembled construction method helps ensure the construction period and avoids the risk of deformation and fall-off of the grille caused by excessive wind pressure and load. Each grille unit 16 is made of aluminum alloy.

[0197] Each grille unit 16 includes an integrally formed grille main structure 5, a transverse frame 17 installed on the inner side of the grille main structure 5, and vertical frames 18 arranged on the left and right sides of the grille main structure 5; the transverse frame 17 is installed horizontally on the glass curtain wall, and the vertical frame 18 is installed longitudinally on the glass curtain wall. The inner side of the grille main structure 5 and the left and right ends of the grille main structure 5 are respectively installed on the transverse frame 17 and the vertical frame 18.

[0198] The main grille structure 5 is wing-shaped and integrally formed. The inner side of the top of the main grille structure 5 is recessed inward to form a mounting hole. Each main grille structure 5 is mounted on the transverse frame 17 via a first inner angle screw 7 in the mounting hole.

[0199] The inner side of the top of the grille main structure 5 is recessed inward to form a decorative light trough 9. There is at least one decorative light trough 9. Each decorative light trough 9 is arranged horizontally. The lighting assembly is an LED light strip installed horizontally in the decorative light trough 9.

[0200] Specifically, the LED light strip is secured to the decorative light trough 9 via screws at the rear of the base. Lighting circuit wiring 14 is routed through openings within the grille's internal structure and into the electrical box. The LED light strip utilizes a "buried" design to ensure a consistent and aesthetically pleasing color throughout the grille. The assembled, ultra-long linear light strip creates a richer lighting effect for the glass curtain wall structure.

[0201] The drainage channel is a drainage hole 13 provided at the bottom of the decorative lamp trough 9 and communicating with the bottom of the grille main structure 5 . The number of the drainage hole 13 is at least one.

[0202] Specifically, the drainage structure promotes drainage efficiency through the structural slope of the grille itself on the one hand, and on the other hand, weather-resistant glue is not applied between adjacent grille joints and milling holes, which provides a second guarantee for drainage efficiency and effectively prevents the problem of wire short circuit caused by water accumulation in the decorative lamp trough 9.

[0203] Weatherproof sealant is not applied to the upper and lower milling holes in the grille lighting fixture slots, the joints between adjacent grilles, or the milling holes. Neutral weatherproof sealant is used to seal the joints between adjacent grilles and the gaps between the curtain wall horizontal keels.

[0204] The transverse skeleton 17 includes a curtain wall aluminum alloy transverse frame 2 arranged inside the glass curtain wall, an aluminum alloy pressure plate 4 arranged outside the glass curtain wall, and a stainless steel bolt assembly 6 for connecting the curtain wall aluminum alloy transverse frame 2 and the aluminum alloy pressure plate 4. Each grid main structure 5 is installed on the aluminum alloy pressure plate 4 through the first internal angle screw 7 in the mounting hole.

[0205] Specifically, after the curtain wall glass 1 is installed, the transverse framework 17 is secured by bolting the aluminum alloy pressure plate 4 to the slots of the curtain wall aluminum alloy transverse frame 2 using stainless steel bolt assemblies 6. The integrated aluminum alloy pressure plate 4 and curtain wall aluminum alloy transverse frame 2 together serve as the transverse load-bearing structure of the single-piece airfoil grille. The aluminum alloy pressure plate 4 serves as both a fixing fixture for the curtain wall glass 1 and a transverse support for the airfoil grille installation. By distributing the load on the aluminum alloy pressure plate 4, which is the same length as the grille, the stability of the transverse framework 17 is ensured.

[0206] The aluminum alloy pressing plate 4 serves as a connector to connect the glass curtain wall aluminum alloy horizontal frame 2 and the tail of the grille main structure 5, which helps to ensure the lateral force dispersion of the grille main structure 5 and the overall straightness of adjacent grille main structures 5.

[0207] Each vertical frame 18 includes a curtain wall aluminum alloy column 3 embedded in the glass curtain wall, a stainless steel cantilever 10 arranged on the outside of the glass curtain wall, and a second internal angle screw 19 for connecting the curtain wall aluminum alloy column 3 and the stainless steel cantilever 10. The left and right sides of each grid main structure 5 are connected to the corresponding stainless steel cantilever 10 through a locking assembly.

[0208] Specifically, the vertical frame 18 is positioned in sections using a theodolite. After the left and right stainless steel picks 10 of the grille are leveled to the same height, the second inner angle screws 19 are used to lock the bottom plate of the stainless steel pick 10 into the slot of the curtain wall aluminum alloy column 3.

[0209] The locking assembly includes a plurality of spring latches 11 and an end aluminum fixing member 12. The plurality of spring latches 11 are connected between two adjacent grid main structures 5 in a staggered state.

[0210] Specifically, four stainless steel spring latches 11 are offset through stainless steel picks 10 and connected to dedicated holes on the sides of the grille main structure 5. After the two adjacent grille main structures 5 are uniformly leveled, the ends are plugged in and secured with aluminum fasteners. The staggered installation of the latches and the plug-in fastening of the ends help ensure the stability of the grille main structure 5; uniform leveling also reduces errors in the overall straightness of the grille main structure 5.
