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

[0039] The general project manager shall organize the civil engineering and curtain wall professional management, technical personnel, and operating personnel to check the completion status of the civil engineering division to see if 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, the completed main body is scanned using 3D scanning technology to generate a point cloud model, which is then combined with the curtain wall BIM model in order 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 according to the elevation control point position handed over by the civil engineering;

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

[0045] S63. The structural design drawings use the axis as the base point to calculate the spacing of the horizontal rear embedded plates along the beam, and calculate 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, the next construction step will be carried out only after the accuracy is within the allowable deviation range.

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

[0049] According to the measurement and layout results, the hole is cleaned before installing the rear embedded plate, and the dust in the hole is cleaned before installing the rear cut mechanical anchor bolt 23;

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

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

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

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

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

[0055] S91. Install the channel steel connectors according to the center line and grid line drawn by the layout. Spot welding is performed first. After the whole layer is corrected, full welding and repair welding are performed uniformly. The weld must be full and dense, and no welding defects such as slag inclusion, pores, and false welding should occur.

[0056] S92. After the welding is completed and the team self-inspects and passes, the project's full-time quality inspector will inspect it. After confirming that there are no quality defects, 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-inspection 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 through the stainless steel bolt assembly 6, and the curtain wall aluminum alloy cross frame 2 is installed and reliably connected to the curtain wall aluminum alloy columns 3 through the stainless steel spring latch 11. The upper and lower curtain wall aluminum alloy columns 3 are connected through the aluminum alloy insert. The installation direction of the same floor is from bottom to top. When installed at a certain height, it is checked, adjusted, corrected, and fixed. The quality meets the design and construction quality acceptance specifications.

[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 specific steps for installing the curtain wall fire protection, lightning protection, and thermal insulation system are as follows:

[0062] The gaps between the glass curtain wall and the interlayer 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, hot-dip galvanized steel plate 20 is used for support, and the joint gaps are effectively sealed with fireproof sealant to ensure that a fully enclosed isolation zone is formed with the floor or wall;

[0063] The lightning protection system of the main structure is connected by welding and painted with anti-rust paint. The overlap length is at least 100mm, and triangular full welding is used; the lightning protection steel bars are hot-dip galvanized and painted with anti-rust paint after welding; lightning protection belts should be installed at parts 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 body; before installing the lightning protection wire, the surface coating of the aluminum profile must be removed to ensure that the weld is full and firm, and no leakage or arbitrary changes in the node position are allowed;

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

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

[0066] After the above process 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 with Party A;

[0067] The acceptance contents include post-embedded parts 24, firm keel connection, lightning protection grounding and devices, etc.; the hidden acceptance raw material entry 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 form: The glass frame is bonded to the glass horizontally, and the glass frame and the beam are fixedly connected at a fixed distance by stainless steel bolts through the decorative cover plate 8; the glass is fixed vertically by a full-length aluminum alloy pressure block, and the pressure block and the column are fixedly connected at a fixed distance by 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 of installing the aluminum composite panel and the aluminum single panel 28 are as follows:

[0072] The aluminum veneer 28, the aluminum composite panel and the 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, corner pieces, reinforcement ribs and frame are installed in the assembly plant, labels are attached to each panel.

[0074] Install it on the aluminum alloy frame with self-drilling and self-tapping 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 procedures of the glass curtain wall, install the glass curtain wall transverse keel and the glass curtain wall wing-type decorative grille structure (which serves as both a glass fixing fixture and a wing grille installation support);

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

[0078] S152. The vertical skeleton 18 on the side of the decorative grille is positioned in sections by the theodolite. After the left and right stainless steel cantilevers 10 of the grille are leveled to the same height, the rear end bottom plate of the stainless steel cantilevers 10 is locked and fixed in the slot of the curtain wall aluminum alloy column 3 by 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 pins 11 are used, which are staggered through the stainless steel pick 10 and pinned into the special holes on the side of the decorative grille. After the left and right grilles are uniformly leveled, the ends are plugged and fixed with aluminum fixings; the staggered installation of the pins and the end plug-in fixing help to ensure the stability of the wing-type grille; the uniform leveling reduces the error control of the overall straightness of the wing-type grille;

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

[0081] S154. Repeat the above process until all glass curtain wall wing-type 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 through 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 and closed" method to ensure that the overall color tone of the wing-style decorative grille is consistent and beautiful. 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 without the use of weather-resistant glue 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 used between adjacent grille joints or milling holes, thereby providing a secondary guarantee for drainage efficiency and effectively preventing 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 days, gusts above level 5 or in summer with sandstorms;

[0089] S164, keep a certain distance and even force when applying glue 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 different materials of the wing grille and the glass curtain wall aluminum alloy, masking tape should be used for protection to avoid contamination;

[0091] S166. Choose professional and skilled workers to apply glue.

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

[0093] 1. A composite curtain wall system with a wing-type decorative grille and a construction method effectively solve the problem of accurate and rapid construction and high-quality adjustment of each unit module of the composite curtain wall in the decoration project with a tight construction period. All components are assembled and installed throughout the process, which reduces the secondary processing procedures on site, facilitates construction, and improves the construction efficiency of decoration, lighting, and drainage projects. At the same time, it also avoids secondary damage to the components of each system at the construction site and reduces the loss rate.

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

[0140] The general project manager shall organize the civil engineering and curtain wall professional management, technical personnel, and operating personnel to check the completion status of the civil engineering division to see if 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.

[0141] In step S5, the specific contents of the error check of the civil engineering structure 25 are as follows:

[0142] In order to ensure the overall effect of the facade, the completed main body is scanned using 3D scanning technology to generate a point cloud model, which is then combined with the curtain wall BIM model in order 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 according to the elevation control point position handed over by the civil engineering;

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

[0146] S63. The structural design drawings use the axis as the base point to calculate the spacing of the horizontal rear embedded plates along the beam, and calculate 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, the next construction step will be carried out only after the accuracy is within the allowable deviation range.

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

[0150] According to the measurement and layout results, the hole is cleaned before installing the rear embedded plate, and the dust in the hole is cleaned before installing the rear cut mechanical anchor bolt 23;

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

[0152] The model, specification and bolt quantity of each post-embedded part 24 must meet the design requirements, and each anchor bolt must be tightened without 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 test and the testing organization shall issue a qualified test report. The next construction process shall not be started before the test is qualified.

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

[0156] S91. Install the channel steel connectors according to the center line and grid line drawn by the layout. Spot welding is performed first. After the whole layer is corrected, full welding and repair welding are performed uniformly. The weld must be full and dense, and no welding defects such as slag inclusion, pores, and false welding should occur.

[0157] S92. After the welding is completed and the team self-inspects and passes, the project's full-time quality inspector will inspect it. After confirming that there are no quality defects, 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-inspection 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 through the stainless steel bolt assembly 6, and the curtain wall aluminum alloy cross frame 2 is installed and reliably connected to the curtain wall aluminum alloy columns 3 through the stainless steel spring latch 11. The upper and lower curtain wall aluminum alloy columns 3 are connected through the aluminum alloy insert. The installation direction of the same floor is from bottom to top. When installed at a certain height, it is checked, adjusted, corrected, and fixed. The quality meets the design and construction quality acceptance specifications.

[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 system are as follows:

[0163] The gaps between the glass curtain wall and the interlayer 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, hot-dip galvanized steel plate 20 is used for support, and the joint gaps are effectively sealed with fireproof sealant to ensure that a fully enclosed isolation zone is formed with the floor or wall;

[0164] The lightning protection system of the main structure is connected by welding and painted with anti-rust paint. The overlap length is at least 100mm, and triangular full welding is used; the lightning protection steel bars are hot-dip galvanized and painted with anti-rust paint after welding; lightning protection belts should be installed at parts 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 body; before installing the lightning protection wire, the surface coating of the aluminum profile must be removed to ensure that the weld is full and firm, and no leakage or arbitrary changes in the node position are allowed;

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

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

[0167] After the above process 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 with Party A;

[0168] The acceptance contents include post-embedded parts 24, firm keel connection, lightning protection grounding and devices, etc.; the hidden acceptance raw material entry 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 panel are as follows:

[0170] Connection form: The glass frame is bonded to the glass horizontally, and the glass frame and the beam are fixedly connected at a fixed distance by stainless steel bolts through the decorative cover plate 8; the glass is fixed vertically by a full-length aluminum alloy pressure block, and the pressure block and the column are fixedly connected at a fixed distance by 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, the aluminum composite panel and the 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, corner pieces, reinforcement ribs and frame are installed in the assembly plant, labels are attached to each panel.

[0175] Install it on the aluminum alloy frame with self-drilling and self-tapping 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 procedures of the glass curtain wall, install the glass curtain wall transverse keel and the glass curtain wall wing-type decorative grille structure (which serves as both a glass fixing fixture and a wing grille installation support);

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

[0179] S152. The vertical skeleton 18 on the side of the decorative grille is positioned in sections by the theodolite. After the left and right stainless steel cantilevers 10 of the grille are leveled to the same height, the rear end bottom plate of the stainless steel cantilevers 10 is locked and fixed in the slot of the curtain wall aluminum alloy column 3 by 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 pins 11 are used, which are staggered through the stainless steel pick 10 and pinned into the special holes on the side of the decorative grille. After the left and right grilles are uniformly leveled, the ends are plugged and fixed with aluminum fixings; the staggered installation of the pins and the end plug-in fixing help to ensure the stability of the wing-type grille; the uniform leveling reduces the error control of the overall straightness of the wing-type grille;

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

[0182] S154. Repeat the above process until all glass curtain wall wing-type 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 through 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 and closed" method to ensure that the overall color tone of the wing-style decorative grille is consistent and beautiful. 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 without the use of weather-resistant glue 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 used between adjacent grille joints or milling holes, thereby providing a secondary guarantee for drainage efficiency and effectively preventing 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 up any impurities or dust on the surface;

[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 days, gusts above level 5 or in summer with sandstorms;

[0190] S164, keep a certain distance and even force when applying glue 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 different materials of the wing grille and the glass curtain wall aluminum alloy, masking tape should be used for protection to avoid contamination;

[0192] S166. Choose professional and skilled workers to apply glue.

[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 two adjacent grille units 16 are locked by a locking assembly, each grille unit 16 is provided with a decorative lamp trough 9 for installing decorative lamps, each decorative lamp trough 9 is provided with a drainage channel, and each decorative lamp 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 a vertical frame 18 arranged on the left and right sides of the grille main structure 5; the transverse frame 17 is installed transversely 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 unit 16 are easy to install, and the components are produced in units by the manufacturer. The assembled construction is conducive to ensuring the construction period, and at the same time, it avoids the risk of deformation and falling 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 a vertical frame 18 arranged on the left and right sides of the grille main structure 5; the transverse frame 17 is installed transversely 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 grille main structure 5 is wing-shaped as a whole and is integrally formed. The inner side of the top of the grille main structure 5 is recessed inward to form a mounting hole. Each grille main structure 5 is mounted on the transverse frame 17 by 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 fixed in the decorative light slot 9 by the screws at the tail of the base, and the lamp circuit threading 14 is led into the electrical box through the opening of the internal structure of the grille. The LED light strip adopts the method of "buried closing" to ensure that the overall color tone of the machine grille is consistent and beautiful. At the same time, the assembled super-long linear light strip presents a richer lighting effect for the glass curtain wall structure.

[0201] The drainage channel is a drainage hole 13 which is arranged at the bottom of the decorative lamp groove 9 and is connected 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 glue is not applied to the upper and lower milling holes in the slots of grille lamps, the joints between adjacent grilles, and the milling holes. Neutral weatherproof sealant is used to seal the joints between adjacent grilles and the gaps between the horizontal keels of the curtain wall.

[0204] The transverse frame 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 grille main structure 5 is installed on the aluminum alloy pressure plate 4 through the first internal angle screw 7 in the installation hole.

[0205] Specifically, after the curtain wall glass 1 is installed, the stainless steel bolt assembly 6 is used to bolt the aluminum alloy pressure plate 4 and the curtain wall aluminum alloy horizontal frame 2 to fix the transverse frame 17. The aluminum alloy pressure plate 4 and the curtain wall aluminum alloy horizontal frame 2, which are designed in an integrated manner, together serve as the transverse force-bearing structure of the single-piece wing-type grille; the aluminum alloy pressure plate 4 serves as both a fixing fixture of the curtain wall glass 1 and a transverse support for the installation of the wing-type grille. The aluminum alloy pressure plate 4, which is the same length as the grille, distributes the force, ensuring the stability of the distributed force of the transverse frame 17.

[0206] The aluminum alloy pressing plate 4 is used as a connecting piece to connect the glass curtain wall aluminum alloy cross frame 2 and the rear end of the grille main structure 5, which helps to ensure the lateral dispersion of the grille main structure 5 and the overall straightness of the 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 outside 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 grille 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 by a theodolite, and after the left and right stainless steel cantilevers 10 of the grille are leveled to the same height, the second inner angle screws 19 are used to lock and fix the bottom plate of the stainless steel cantilevers 10 at the rear ends into the slots of the curtain wall aluminum alloy columns 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 pins 11 are used, which are staggered through the stainless steel pick 10 and connected to the special holes on the side of the grille main structure 5. After the two adjacent grille main structures 5 on the left and right are uniformly leveled, the ends are plugged and fixed with aluminum fixings. The staggered installation of the pins and the end plug-in fixation help to ensure the stability of the grille main structure 5; the uniform leveling reduces the error control of the overall straightness of the grille main structure 5.
