Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a construction method for an aluminum alloy frame glass curtain wall. Background Technology

[0002] Currently, traditional aluminum alloy frame glass curtain wall construction methods often suffer from the following shortcomings: Measurement and layout rely on manual experience, making them susceptible to structural errors, resulting in uneven curtain wall panels and inconsistent joints. The installation of transition pieces and keels lacks systematic correction, and verticality and horizontality are not strictly controlled, leading to uneven curtain wall surfaces. During glass panel installation, insufficient inspection and adjustment can easily result in misalignment and loose sealant joints, affecting aesthetics and sealing. Improper installation of insulation and fireproofing materials leads to poor insulation or fireproofing failure. Insufficient cleaning of joints before sealant application results in weak adhesion and leakage. The overall construction process is loose, lacking standardized acceptance procedures, leading to significant quality fluctuations.

[0003] This solution, based on traditional methods, introduces detailed measurement, calibration, acceptance, and protection steps, forming a systematic construction process. Summary of the Invention

[0004] To address the above problems, this invention discloses a construction method for aluminum alloy frame glass curtain walls.

[0005] The specific plan is as follows: A construction method for aluminum alloy frame glass curtain walls. S1. Measurement and layout; used to ensure the accuracy of the benchmark for curtain wall installation, providing position and elevation basis for subsequent installation, and avoiding cumulative errors; S2. Install adapter; used to connect the curtain wall structure and the main structure, providing reliable support points and ensuring load transfer; S3. Vertical keel installation; used to establish the vertical support structure of the curtain wall, bear the vertical load, and provide a foundation for the installation of horizontal keels and glass; S4. Vertical keel alignment and acceptance; used to ensure the verticality, horizontality and grid dimensions of the vertical keel are accurate, and to guarantee the overall flatness and quality of the curtain wall. S5. Vertical keel protective film packaging; used to protect the surface of aluminum profiles from construction pollution and damage, maintain their appearance, and extend their service life; S6. Measurement, positioning, and layout of floor height and horizontal keel; used to accommodate building structural errors, provide precise positions for horizontal keel installation, and ensure the horizontality and uniformity of horizontal keel division; S7. Horizontal keel installation; used to establish the horizontal support structure of the curtain wall, connect the vertical keels, form a frame system, and bear horizontal loads. S8, installation of thermal insulation cotton, fireproof cotton and interlayer aluminum panels; used to provide thermal insulation and fireproof performance, enhance the safety and energy efficiency of the curtain wall, and improve the building envelope; S9. Glass panel installation; used to install glass panels to form the appearance of a curtain wall, realize the functions of lighting and viewing, and ensure sealing and safety. S10, Apply sealant and install aluminum alloy decorative strips; used to seal joints, prevent water and air penetration, and enhance the durability and aesthetics of the curtain wall.

[0006] Further, in step S1, based on the control axes and control elevation points during the construction of the civil structure, the secondary benchmark control lines and elevation control points required for the installation of the glass curtain wall are measured and laid out. On this basis, the positioning lines of the centerline and outer edge of the glass curtain wall are measured and laid out. The position control benchmark lines for the installation of the transition components are marked with ink lines, and triangular markers are made at both ends with red paint. Simultaneously, the elevation of the structure and the dimensions of the embedded parts are checked, the data is recorded, and feedback is given to the supervisor, owner, and general contractor. Specifically, a level, theodolite, ink lines, and red paint are used. The level is used for leveling, the theodolite is used to measure the vertical control lines, the ink lines are used for marking, and the red paint is used for marking.

[0007] Further, in step S2, after the embedded part processing and measurement layout are completed, the adapter is installed. First, check whether the center line of the embedded part is consistent with the positioning line of the support, and check the left-right and up-down deviations of the embedded part using the cross positioning line. If the deviation is large, report to the design department for adjustment. When installing the post-embedded part, follow the layout position. Conduct a comprehensive inspection of the installed adapter, including corrosion protection, specifications, and adjustment position. Specifically, hand tools such as wrenches and bolts are used. Wrenches are used to tighten bolts, and bolts are used to fix the adapter.

[0008] Further, in step S3, the model and specifications (including color, cross-section, and length) of the vertical keel are checked and aligned. Installation proceeds from bottom to top, with the end with the core sleeve facing upwards. The first vertical keel is fixed at its upper end as a suspension component, and the lower end is fixed after adjustment. The lower end of the second vertical keel is aligned with the core sleeve at the upper end of the first keel, leaving a 21mm expansion joint, and then the upper end is installed using a plumb line or alignment. After installation, initial adjustments are made in three dimensions, with an error of <1mm. Specifically, a large electric drill, a φ12.5 drill bit, a wrench, and a wooden mallet were used. The electric drill is used for drilling holes, the wrench for tightening bolts, and the wooden mallet for light tapping adjustments.

[0009] Further, in step S4, the following steps are performed: laying out the baseline (vertical baseline), drawing the horizontal line (closed horizontal line), establishing the reference plane, calibrating the ruler, measuring errors (out-of-plane error, in-plane vertical error, spacing error), adjusting errors (by lightly tapping with a wooden block or loosening bolts), checking errors with a theodolite, positioning, organizing acceptance (accepted separately by the project manager and the company), recording the acceptance results and signing them. Specifically, a hammer, a tensioner, a level, and a theodolite are used. The hammer is used for adjustment, the tensioner for pulling the line, the level for horizontal measurement, and the theodolite for checking vertical errors.

[0010] Further, in step S5, a plastic film is selected, the surface of the vertical keel is cleaned, and the vertical keel is wrapped from the inside out. Adhesive tape is used to secure it, and any omissions or irregularities are checked. The packaging is done in one layer, with joints connected but not overlapping. Specifically, plastic film, adhesive tape, and white cloth are used. The plastic film is used for wrapping, the adhesive tape for securing, and the white cloth for cleaning the surface.

[0011] Further, in step S6, a level is used to level each floor, measure floor and floor height errors, analyze the errors, formulate an adjustment plan (for approval), and after adjustment, draw a vertical cross-sectional view of the horizontal keel installation. Lines are laid out on the vertical keels (dividing from the middle upwards and downwards) to check accuracy and levelness. Specifically, a level and a measuring tape are used. The level is used for leveling, and the measuring tape is used for measuring distances and errors.

[0012] Furthermore, step S7 includes the installation of positioning pins, the installation of anti-vibration washers for the horizontal keel, and the installation of the horizontal keel itself; preparation of documents, materials, and site cleanup before construction; inspection of the quality of the horizontal keel (e.g., whether the punching is standardized and whether there are burrs); and inspection of the positioning after installation (whether there is misalignment, whether the interfaces fit, whether the washers are neat, whether they are level, etc.). Specifically, manual tools such as screwdrivers are used. Screwdrivers are used to install bolts and washers.

[0013] Further, in step S8, fireproof cotton and thermal insulation cotton are cut according to the design drawings and installed inside the fireproof steel plate or between the frame and the wall (leaving a gap between the thermal insulation cotton and the wall); the interlayer aluminum plate is installed, dust is removed, the aluminum plate is lifted to the installation position, and fixed to the frame with self-drilling self-tapping screws, adjusting the gaps and verticality of adjacent aluminum plates; after the fireproof cotton is installed, the surface is sealed with wire mesh. Specifically, wire mesh and self-drilling self-tapping screws are used. The wire mesh is used to seal the fireproof cotton, and the self-drilling self-tapping screws are used to fix the aluminum plate.

[0014] Furthermore, in step S9, the process includes construction preparation (personnel, materials, site cleanup), inspection and acceptance of glass panels (specifications, quantity, misalignment, damage, structural adhesive, etc.), stacking glass in layers, initial installation (locating glass, transporting glass, adjusting direction, lifting to the installation position, aligning adhesive joints, installing pressure plates and fasteners), adjustment (horizontal alignment, vertical alignment, surface flatness), fixing (tightening with pressure plates), and acceptance (checking panel misalignment, joint quality, and concealed works records). Specifically, suction cups, electric drills, and screwdrivers were used. Suction cups were used to move the glass, electric drills were used to drill holes, and screwdrivers were used to fix the pressure plates.

[0015] Further, in step S10, the spacing and flatness of the exterior trim panels are checked, foam strips are inserted (to a consistent depth), protective tape is applied (width not less than 25mm), the joint surface is cleaned (with alcohol or detergent), adhesive is injected (a compatibility test is performed first), adhesive is repaired (using a scraper to smooth, flat, and even the surface), and cleaning is performed (cleaning the exterior trim, removing the tape, and removing the protective film); the aluminum alloy decorative strip is then installed. Specifically, alcohol, detergent, a scraper, and tape are used. Alcohol is used for cleaning, the scraper for repairing adhesive, and the tape for protection.

[0016] The beneficial effects of this invention are as follows: Through multiple measurements, layouts, and corrections, errors are reduced, ensuring the flatness and verticality of the curtain wall and improving its appearance quality. Error analysis and adjustment schemes adapt to structural deviations, avoiding rework. Protective film packaging and standardized operations reduce damage and contamination to aluminum profiles and glass, extending their service life. Standardized installation of insulation cotton, fireproof cotton, and sealant improves the curtain wall's insulation, fireproofing, and sealing performance, enhancing safety and energy efficiency. Standardized processes and acceptance procedures reduce repetitive work, improve construction efficiency, and lower costs and risks. Recording acceptance data and concealed works information facilitates quality monitoring and subsequent maintenance. Attached Figure Description

[0019] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0020] This invention provides a construction method for aluminum alloy frame glass curtain walls, addressing the following technical problems: Accumulated installation errors due to inaccurate measurement and layout in traditional curtain wall construction are resolved by ensuring accurate positioning through precise measurement and error adjustment. Difficulties in adjusting vertical and horizontal keels during installation, affecting overall flatness and verticality, are addressed by ensuring three-dimensional accuracy through a calibration and acceptance process. Misalignment and inadequate sealing of glass panels are improved through inspection, adjustment, and fixing steps. The mismatch between building structural errors and curtain wall segmentation is addressed through adaptive adjustment using floor height measurement and error analysis. Insufficient material protection leading to damage to aluminum profiles and glass is addressed by reducing contamination and damage through protective film packaging and standardized installation procedures. Insufficient insulation, fireproofing, and sealing performance are addressed by enhancing functionality and safety through the installation of insulation cotton, fireproof cotton, and sealant.

[0021] As shown in the figure, the specific steps are as follows: S1. Measurement and layout; used to ensure the accuracy of the benchmark for curtain wall installation, providing position and elevation basis for subsequent installation, and avoiding cumulative errors. S2. Install adapter; used to connect the curtain wall structure and the main structure, providing reliable support points and ensuring load transfer; S3. Vertical keel installation; used to establish the vertical support structure of the curtain wall, bear the vertical load, and provide a foundation for the installation of horizontal keels and glass; S4. Vertical keel alignment and acceptance; used to ensure the verticality, horizontality and grid dimensions of the vertical keel are accurate, and to guarantee the overall flatness and quality of the curtain wall. S5. Vertical keel protective film packaging; used to protect the surface of aluminum profiles from construction pollution and damage, maintain their appearance, and extend their service life; S6. Measurement, positioning, and layout of floor height and horizontal keel; used to accommodate building structural errors, provide precise positions for horizontal keel installation, and ensure the horizontality and uniformity of horizontal keel division; S7. Horizontal keel installation; used to establish the horizontal support structure of the curtain wall, connect the vertical keels, form a frame system, and bear horizontal loads. S8, installation of thermal insulation cotton, fireproof cotton and interlayer aluminum panels; used to provide thermal insulation and fireproof performance, enhance the safety and energy efficiency of the curtain wall, and improve the building envelope; S9. Glass panel installation; used to install glass panels to form the appearance of a curtain wall, realize the functions of lighting and viewing, and ensure sealing and safety. S10, Apply sealant and install aluminum alloy decorative strips; used to seal joints, prevent water and air penetration, and enhance the durability and aesthetics of the curtain wall.

[0022] In step S1, based on the control axes and elevation points established during the construction of the civil structure, the secondary reference control lines and elevation control points required for the installation of the glass curtain wall are measured and laid out. On this basis, the positioning lines for the centerline and outer edge of the glass curtain wall are measured and laid out. The position control reference lines for the installation of the transition components are marked with ink lines, and triangular markers are made at both ends with red paint. Simultaneously, the elevation of the structure and the dimensions of embedded parts are checked, the data is recorded, and feedback is provided to the supervisor, owner, and general contractor. Specifically, a level, theodolite, ink lines, and red paint are used. The level is used for leveling, the theodolite for measuring vertical control lines, the ink lines for marking, and the red paint for marking.

[0023] In step S2, after the embedded part processing and measurement layout are completed, the adapter is installed. First, check whether the center line of the embedded part is consistent with the positioning line of the support. Check the left-right and up-down deviations of the embedded part using the cross positioning line. If the deviation is large, report to the design department for adjustment. When installing the post-installed embedded part, follow the layout position. Conduct a comprehensive inspection of the installed adapter, including corrosion protection, specifications, and adjustment position. Specifically, hand tools such as wrenches and bolts are used. Wrenches are used to tighten bolts, and bolts are used to fix the adapter.

[0024] In step S3, check the model and specifications (including color, cross-section, and length) of the vertical keel and align them accordingly. Installation proceeds from bottom to top, with the end with the core sleeve facing upwards. Fix the upper end of the first vertical keel as a suspension component, adjust it, and then fix the lower end. Align the lower end of the second vertical keel with the core sleeve at the upper end of the first keel, leaving a 21mm expansion joint, and then install the upper end using a plumb line or alignment. After installation, perform initial adjustments in three dimensions, ensuring the error is <1mm. Specifically, a large electric drill, a φ12.5 drill bit, a wrench, and a wooden mallet were used. The electric drill was used for drilling holes, the wrench for tightening bolts, and the wooden mallet for light tapping adjustments.

[0025] In step S4, the baseline (vertical baseline) is laid out, the horizontal line (closed horizontal line) is drawn, a reference plane is established, the ruler is calibrated, and errors (out-of-plane error, in-plane vertical error, spacing error) are measured. Errors are adjusted (by lightly tapping with a wooden block or loosening bolts). Errors are checked with a theodolite, the location is determined, and acceptance is organized (by the project manager and the company respectively). The acceptance results are recorded and signed. Specifically, a hammer, a tensioner, a level, and a theodolite are used. The hammer is used for adjustment, the tensioner for stringing, the level for horizontal measurement, and the theodolite for vertical error verification.

[0026] In step S5, a plastic film is selected, the surface of the vertical keel is cleaned, and the film is wrapped around the vertical keel from the inside out. Adhesive tape is used to secure it, and any omissions or irregularities are checked. The packaging is done in one layer, with joints connected but not overlapping. Specifically, plastic film, adhesive tape, and white cloth are used. The plastic film is used for wrapping, the adhesive tape for securing, and the white cloth for cleaning the surface.

[0027] In step S6, a level is used to level each floor, measure floor and floor height errors, analyze the errors, formulate an adjustment plan (for approval), and after adjustment, draw a vertical cross-sectional view of the horizontal joists installation. Lines are laid out on the vertical joists (dividing from the middle upwards and downwards) to check accuracy and levelness. Specifically, a level and a measuring tape are used. The level is used for leveling, and the measuring tape is used for measuring distances and errors.

[0028] Step S7 includes the installation of positioning pins, the installation of anti-vibration washers for the horizontal keel, and the installation of the horizontal keel itself; preparation of documents and materials and site cleanup before construction; inspection of the quality of the horizontal keel (e.g., whether the punching is standardized and whether there are burrs); and inspection of the positioning after installation (whether there is misalignment, whether the interfaces fit, whether the washers are neat, whether they are level, etc.). Manual tools such as screwdrivers are used. Screwdrivers are used to install bolts and washers.

[0029] In step S8, fireproof cotton and thermal insulation cotton are cut according to the design drawings and installed inside the fireproof steel plate or between the frame and the wall (leaving a gap between the thermal insulation cotton and the wall); the interlayer aluminum plate is installed, dust is removed, the aluminum plate is lifted to the installation position, and fixed to the frame with self-drilling self-tapping screws, adjusting the gaps and verticality of adjacent aluminum plates; after the fireproof cotton is installed, the surface is sealed with wire mesh. Specifically, wire mesh and self-drilling self-tapping screws are used. The wire mesh is used to seal the fireproof cotton, and the self-drilling self-tapping screws are used to fix the aluminum plate.

[0030] In step S9, the process includes construction preparation (personnel, materials, site cleanup), inspection and acceptance of glass panels (specifications, quantity, misalignment, damage, structural adhesive, etc.), stacking glass in layers, initial installation (locating glass, transporting glass, adjusting direction, lifting to the installation position, aligning adhesive joints, installing pressure plates and fasteners), adjustment (horizontal alignment, vertical alignment, surface flatness), fixing (tightening with pressure plates), and acceptance (checking panel misalignment, joint quality, and concealed works records). Suction cups, electric drills, and screwdrivers were specifically used. Suction cups were used to move the glass, electric drills were used to drill holes, and screwdrivers were used to fix the pressure plates.

[0031] In step S10, the spacing and flatness of the exterior panel pieces are checked, foam strips are inserted (to a consistent depth), protective tape is applied (width not less than 25mm), the joint surface is cleaned (with alcohol or detergent), adhesive is injected (a compatibility test is performed first), adhesive is repaired (using a scraper to smooth, flat, and even the surface), and cleaning is completed (cleaning the exterior surface, removing the tape, and removing the protective film); the aluminum alloy decorative strip is then installed. Specifically, alcohol, detergent, a scraper, and tape are used. Alcohol is used for cleaning, the scraper for repairing adhesive, and the tape for protection.
