Description

Technical Field

[0001] This application relates to the field of glass curtain wall installation technology, and in particular to a vertically visible and horizontally concealed glass curtain wall structure and construction method. Background Technology

[0002] Glass curtain walls are an aesthetically pleasing and novel method of architectural wall decoration, a prominent feature of the modernist high-rise building era. With the rapid development of the construction industry, glass curtain walls are widely used in various types of buildings. However, existing construction techniques for vertical and horizontal concealed glass curtain walls are relatively traditional and cumbersome, especially during the installation and fixing process. Controlling the flatness and stability of the glass curtain wall is difficult, and the subsequent dismantling and maintenance are also challenging.

[0003] The existing technology still has the following problems:

[0004] 1. The existing construction methods for vertical exposed and horizontal concealed glass curtain walls have relatively poor safety during construction, low overall construction efficiency, and difficulty in ensuring that the flatness and stability of the glass curtain wall meet safety standards, requiring multiple rectifications and wasting manpower and resources.

[0054] To address the issues of cumbersome installation processes and insecure fixing during installation, this invention uses a fixing component to secure the connection between the column and the clip, while also enabling quick installation and disassembly. Furthermore, to address the problem of insufficient tightness in the sealing strip connection between glass panes, this invention uses a strip assembly to ensure close contact between the sealing strip and the glass, thereby improving the overall sealing performance of the glass curtain wall.

[0055] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0056] Example 1

[0057] Please see Figure 1 and Figure 2 As shown, a vertically visible and horizontally concealed glass curtain wall structure includes columns 1, a horizontal beam 2 fixedly installed in the middle of the columns 1, a buckle 3 on the outer surface of the columns 1, fixing components 4 in the inner cavities at the upper and lower ends of the columns 1, one end of the fixing component 4 being fixed to the inner cavity of the buckle 3, a sealing strip assembly 5 in the middle of the inner cavity of the horizontal beam 2, a first cover 6 slidably connected to the upper and lower ends of the columns 1, a second cover 7 slidably connected to the outer surface of the horizontal beam 2, and glass panels 8 at the upper and lower ends of the sealing strip assembly 5 extending out of the horizontal beam 2. The glass panel 8 is in close contact with the crossbeam 2 and the buckle 3. The fixing component 4 is located in the inner cavity of the first cover 6. The crossbeam 2 is fixedly installed on the column 1, and the buckle 3 is engaged with the column 1 by the fixing component 4. The adhesive strip component 5 is used for sealing between the glass panels 8 to increase aesthetics and maintain the airtightness between the glass panels 8. The first cover 6 is used to operate the fixing component 4 to quickly separate the buckle 3 and the column 1. The second cover 7 is used for the expansion of the adhesive strip component 5 to make the adhesive strip component 5 and the glass panel 8 fit tightly together.

[0058] Please see Figure 3 , Figure 4 and Figure 5As shown, the fixing component 4 includes a connecting plate 41, a pull block 42 is fixedly installed on the outer surface of the connecting plate 41, and fastening mechanisms 43 are fixedly connected to both ends of the connecting plate 41. A limiting mechanism 44 is sleeved on the end of the fastening mechanism 43 away from the pull block 42. The limiting mechanism 44 and the buckle 3 are fixedly connected. The fastening mechanism 43 includes a moving rod 431, an adjusting rod 432 is rotatably connected to the inner cavity of the moving rod 431, a first retaining ring 433 is slidably connected to the end of the adjusting rod 432 away from the connecting plate 41, and a second retaining ring 434 is fixedly installed on the end of the adjusting rod 432 away from the connecting plate 41. Both the first retaining ring 433 and the second retaining ring 434 are frustoconical and symmetrically distributed. 31 and adjusting rod 432 are connected by threads. Moving rod 431 and column 1 are slidably connected. Limiting mechanism 44 includes fixing ring 441. The inner cavity of fixing ring 441 has a receiving cavity 442. The inner cavity of receiving cavity 442 is provided with a first spring 443. The inner cavity of receiving cavity 442 is provided with elastic rod 444. Elastic rod 444 and first spring 443 are sleeved. One end of elastic rod 444 is fixedly installed with a locking block 445. The locking block 445 and receiving cavity 442 are slidably connected. The locking block 445 and second locking ring 434 are engaged. One side of locking block 445 is an inclined surface, and the inclined surface faces the side of moving rod 431. Fixing ring 441 and buckle 3 are fixedly connected. When fixing column 1 and buckle 3, the first spring 444 is fixedly connected with the second spring 443. The locking ring 441 is fixedly connected with the second spring 443. When fixing column 1 and buckle 3, the locking ring 441 is fixedly connected with the second spring 443. When the cover 6 exposes the inner cavity of the column 1, the movable pull block 42 moves the connecting plate 41 within the inner cavity of the column 1. The movement of the connecting plate 41 causes the moving rod 431 to slide within the inner cavity of the column 1. The sliding of the moving rod 431 causes the second retaining ring 434 to press against the retaining block 445. At this time, the retaining block 445 is compressed and stored in the inner cavity of the storage cavity 442, facilitating the passage of the second retaining ring 434 through the retaining block 445. At this time, the retaining block 445 and the second retaining ring 434 are engaged, making the fixing ring 441 and the moving rod 431 fixedly connected as a whole. Then, by rotating the adjusting rod 432, the adjusting rod 432 moves within the inner cavity of the moving rod 431, making the second retaining ring 434 and the retaining block 445 tightly engaged, thereby making the buckle 3 and the column 1... When the fixed connection needs to be disassembled, push the pull block 42 again to drive the first retaining ring 433 to squeeze the retaining block 445. At this time, the first spring 443 and the adjusting rod 432 are slidably connected, so that the first retaining ring 433 passes through the retaining block 445. After the first retaining ring 433 passes through the retaining block 445, pull the moving rod 431 back. At this time, the first retaining ring 433 squeezes the retaining block 445, causing the first spring 443 to compress, thereby driving the elastic rod 444 to move in the inner cavity of the storage cavity 442 until the first spring 443 and the second retaining ring 434 are tightly fitted. Then the retaining block 445 opens, allowing the first retaining ring 433 and the second retaining ring 434 to pass quickly and fall out of the inner cavity of the fixing ring 441. This allows the buckle 3 to be quickly disassembled, which is convenient for later maintenance.

[0059] Please see Figure 6 and Figure 7 As shown, the sealing strip assembly 5 includes a sealing strip 51, an expansion cavity 52 is provided on one side of the sealing strip 51, and a pressure cylinder 53 is fixedly installed in the middle of the sealing strip 51. The pressure cylinder 53 communicates with the inner cavity of the expansion cavity 52. ​​A first connecting hole 54 is opened at one end of the pressure cylinder 53 near the inner cavity of the expansion cavity 52. ​​A piston block 55 is slidably connected to the inner cavity of the pressure cylinder 53. A pull rod 56 is fixedly installed on the outer surface of the piston block 55. A second spring 57 is sleeved on the outer surface of the pull rod 56. The outer surface of the pressure cylinder 53... A second connecting hole 58 is provided on the surface of the pressure cylinder 53. A cover 59 is slidably connected to the outer surface of the pressure cylinder 53. A rear end cover 510 is provided at the end of the pressure cylinder 53 away from the first connecting hole 54. The sealing strip 51 is located in the middle inner cavity of the crossbeam 2, and the two outer ends of the expansion cavity 52 are tightly fitted to the glass panel 8. The pressure cylinder 53 is located in the cavity at the second cover 7. The first connecting hole 54 is located inside the expansion cavity 52. ​​The second connecting hole 58 is located at the end near the rear end cover 510. The second spring 57 is located between the piston block 55 and the... Between the rear end cover 510 and the pressure cylinder 53, the rear end cover 510 and the pressure cylinder 53 are connected by threads. When the sealing strip 51 is placed in the middle of the glass panel 8, the expansion chamber 52 is expanded to make the sealing strip 51 and the side of the glass panel 8 in tight contact. By rotating the rear end cover 510, the second spring 57 is removed. At this time, the sliding cover 59 exposes the second connecting hole 58. Then, the pull rod 56 is pulled to drive the piston block 55 to move in the inner cavity of the pressure cylinder 53, allowing external air to pass through the second connecting hole 58. Between the piston block 55 and the first connecting hole 54, the piston block 55 is continuously pumped, forcing the air in the inner cavity of the pressure cylinder 53 into the inner cavity of the expansion chamber 52, causing the outer surface of the sealing strip 51 to expand, making it easier to make close contact with the glass panel 8. After the expansion chamber 52 expands, the second spring 57 is placed again between the rear end cover 510 and the piston block 55, generating a squeezing force on the piston block 55, keeping the contents of the expansion chamber 52 from being discharged, so that the side of the glass panel 8 is always in close contact with the outer surface of the sealing strip 51.

[0060] Example 2

[0061] Before construction, preparations include scaffolding erection and site preparation. For large-area curtain walls, the installation will combine on-site installation with factory fabrication, depending on the actual situation. A scaffolding system with a 300mm gap from the wall will be erected for the installation of the curtain wall frame. After the frame installation is complete, the scaffolding will begin to dismantle. When hoisting or using a boom crane for vertical lifting, all on-site scaffolding should have been dismantled, and the road surface should have been completed with crushed stone or a water-stabilized layer. Factory-processed materials should be stored in a well-ventilated, level, dry, and rainproof area, protected from rain and moisture, and kept away from acids, alkalis, salts, and other liquids. To facilitate material transport, the glass should be placed against a sturdy wall at an 80-degree angle to the ground, with soft cushioning material placed at the contact points with the wall. Measurements and layout are required, including verticality, floor height, horizontality, and measurements of irregularly shaped walls. The specific steps are as follows: familiarizing oneself with the building structure and curtain wall design drawings; dividing the entire project into sections and faces; determining the reference measurement layer; determining the reference measurement axis; determining key points; laying out lines; and measuring. Wall decoration construction measurements are also required, with vertical lines drawn on the exterior walls. For the main parts of the keel, use the suspension wire method or plumb line method to measure and record the vertical line along the wall surface, and draw a vertical diagram. Set control points for the vertical keel positions on the uppermost exterior wall surface of the curtain wall, lower the wire to the bottom layer, and simultaneously observe and fix the vertical position of the wire using two theodolites in two mutually perpendicular directions. Establish corresponding control points for the same wire at the uppermost and bottom layers, connect them with wire, and fix them after checking and confirming their conformity using theodolites in two mutually perpendicular directions. The embedded parts connecting the curtain wall and the main structure should be installed according to design requirements, and the measurement and layout error should not exceed ±3mm in height. The left-right and front-back axes of the embedded parts should be consistent. The error must not exceed 10 mm. To ensure the verticality and accurate positioning of the curtain wall, measurements and checks should be performed continuously during frame installation. After checking and measuring the structural dimensions of the entire building, the actual measured structural dimensions should be compared with the curtain wall design dimensions. Lines should be drawn according to the confirmed grid construction drawings. Lines should be drawn after the waterproof layer on the wall is constructed. The upper and lower horizontal lines of the windows should be determined by the design elevation +50 mm line of each floor. After finding the window grid lines, various panel lines should be drawn according to the panel layout plan of each wall. If there is a deviation between the actual dimensions of each window and the design dimensions, the panel joint size can be adjusted if the error is small. The joints should be consistent from top to bottom.

[0062] For the installation of embedded parts, this project uses pre-embedded parts for construction, employing hot-dip galvanized steel flat embedded parts. These embedded parts should be installed during concrete construction to ensure accurate positioning. The placement of the embedded parts should be controlled according to the axis, ensuring their entry and exit points and elevation positioning are secure and safe. After locating the positioning points, the legs of the embedded parts should be welded firmly to the main steel reinforcement. The embedded parts should then be installed after the installation process. Measurements should be taken according to the embedded part layout diagram to accurately mark the center line and hole spacing of each embedded part. When using chemical bolts, the hole depth must be controlled (not too deep), the dust inside the hole must be thoroughly cleaned, and the bolts can only bear load after the chemical agent has cured. After the bolts are installed, the adapter should be installed after the curing period, and the top washer, spring washer, and nut should be tightened.

[0063] In the fabrication of curtain wall keel, straightening is a crucial process in steel structure manufacturing, ensuring the quality of the steel structure. For various profiles, if deformation exceeds the standard, straightening should be performed before cutting. Before layout, the construction drawings must be checked, process standards must be familiarized, and the precise dimensions of each component must be mastered to strictly control dimensional accuracy. Measuring tools must be calibrated by a legally recognized metrology unit. Layout should be based on the actual dimensions in the construction drawings. Before marking, the symbols and quantities on the templates should be thoroughly understood, and the reference inspection line should be marked for plate marking. Hole marking should be done according to the gauge hole lines. Cutting: Steel plates are cut using gas cutting. The flatness, cut depth, and local notch depth of the gas-cut steel plates and profiles must meet acceptance requirements. Processing: To eliminate hardening or the formation of a hardened layer in the steel after cutting, ensuring tight and smooth connections between components, processing is carried out. The quality of the weld bevel is ensured; hole making is carried out by drilling on a drilling machine. To ensure the quality of the work, small holes should be punched or drilled on the parts in advance. When assembling the structure, the holes are enlarged to the designed diameter to ensure that the hole wall is not damaged and achieves a smooth hole wall; welding is carried out on site in accordance with the specifications of materials and process requirements. All welds should be uniform, full and free of slag inclusions to ensure welding quality. Fillet welds or welds without specified heights are treated as full welds. The weld height is the thickness of the thinner weldment. The height of the steel angle bracket weld connecting the curtain wall column 1 to the anchor plate is not less than 6mm. Three-sided welding is adopted, and the effective length of a single angle bracket weld is not less than 100mm; rust removal is carried out by mechanical shot blasting. Special rust removal equipment is used for rust removal. Shot blasting can improve the fatigue strength and corrosion resistance of steel.

[0064] For the curtain wall keel installation, all pre-embedded parts of the frame are placed on the outer side of the floor slab shear walls and beams. The shear walls and columns are embedded in the plane, connected by channel steel, and stainless steel tie bolts are used as fasteners. The pre-embedded parts are accurately located, and the connectors are fixed by welding to the embedded parts, connecting the curtain wall structure to the main concrete structure. Therefore, when installing the connectors, first, remove rust from the embedded parts and perform anti-corrosion treatment before welding the connectors. For column 1 installation, the specific steps are: check the model and specifications of column 1, align it in place, and install the lower end of column 1. The installation of column 1 proceeds from bottom to top, with the end containing the core tube facing upwards. The first column 1 is fixed at the top as a suspension component, then the bottom is fixed after adjustment. For the second column 1, the bottom is aligned with the core tube at the top of the first column 1, leaving an expansion joint of at least 20mm. The top of column 1 is then installed using a plumb line or alignment. This process is repeated for each column. After installation, the measurements are compared to the previous steps. For the positioning line, make initial adjustments in the three-dimensional direction, keeping the error <2mm. After the basic installation is completed, make comprehensive adjustments in the next process. Avoid dead angles in bolt installation to maintain the adjustability of bolt holes. When using galvanized angle brackets, do not forget the anti-corrosion treatment between column 1 and the angle bracket. Place EPDM flexible gaskets between the connectors and column 1 to prevent friction noise. After fixing column 1 with tie bolts, calibrate the entire installed column 1. Repeated calibration and inspection of this process is the basic guarantee for the quality of the entire curtain wall. Therefore, the installation of column 1 takes the most time, is the most technically complex, and has the highest precision requirements in curtain wall construction. Adjust the plane error, vertical error, and division error. If necessary, use a theodolite to check the error and perform positioning. After the curtain wall column 1 is hoisted and adjusted, the support is aligned and welded, and then the curtain wall can be hoisted. The curtain wall hoisting should be carried out from bottom to top. Place the hoisting electric trolley on the top of the floor. Install pulleys under the electric trolley. The hoisting equipment should be able to bear a load of 1.0T, use a winch to lift the curtain wall panels. After the curtain wall is lifted, windproof ropes should be installed at its lower end. When the curtain wall is slowly positioned, four workers on the upper level should be prepared to tighten it with screws and wrenches. When the curtain wall is lifted to the installation position, use a long pole to hook the windproof ropes to the upper level for control by the upper level personnel. At this time, the lower end of column 1 is inserted into the steel sleeve core of the upper end of column 1 that has been installed on the lower level. The upper level personnel insert the bolt through the connector hole into the bolt hole of column 1, and washers should be placed in the middle of the bolt. Horizontal beam 2 is installed. The steel horizontal beam 2 is installed by welding stainless steel brackets to the side of column 1. The installation is a continuous installation. After the first horizontal beam 2 is installed, the second horizontal beam 2 is also installed. The floor height and horizontal beam 2 are measured, positioned, and laid out. After the installation and protection of column 1 are completed, the horizontal beam 2 installation is then prepared. The measurement, positioning, and layout of the horizontal beam 2 are adjustments for architectural errors. To ensure the aesthetic requirements of the curtain wall both indoors and outdoors, the vertical division of the curtain wall should be appropriately adjusted according to the design requirements. Adjustments are generally made on a floor-by-floor basis. Layout can only proceed after measurement and positioning. For installation: drill round holes at one end of the horizontal beam 2 for bolts. First, find the correct position, then pre-place the angle brackets of the horizontal beam 2 at both ends. Use stainless steel bolts to pass through the oblong holes in the angle brackets of the horizontal beam 2 for adjustment. Tighten the stainless steel bolts. Simultaneously, check for errors in the positioning of various parts of the horizontal beam 2, whether the interfaces between the horizontal beam 2 and the column 1 match, whether the horizontal beam 2 is level, and whether the outer surface of the horizontal beam 2 is on the same plane as the outer surface of the column 1. Adjust the position of each component to ensure the installation quality of the horizontal beam 2.

[0065] The specific operation for installing a horizontally concealed and vertically exposed steel frame glass curtain wall is as follows: For straight boom truck glass installation: confirm the specifications and dimensions of the panels; place the glass in the safety basket with wooden padding at the bottom; secure the glass with nylon ropes to prevent displacement during boom lifting; one worker enters the safety basket to control the boom lifting; one supervisor constantly observes the movement of personnel on the sidelines; personnel are prohibited from passing within the work area of ​​the articulated boom truck; two workers inside the building wait for glass installation; place the glass in the pre-determined position; tighten the glass clamps with screws at the upper and lower points; adjust the glass installation positioning points; press the clamps into the upper and lower concealed frame grooves of the glass according to the design requirements; and install the next glass panel.

[0066] In summary, by sliding the first cover 6 to expose the inner cavity of the column 1, the movable pull block 42 drives the connecting plate 41 to move within the inner cavity of the column 1. The movement of the connecting plate 41 causes the moving rod 431 to slide within the inner cavity of the column 1. The sliding of the moving rod 431 causes the second retaining ring 434 to press against the retaining block 445. At this time, the retaining block 445 is compressed and stored in the inner cavity of the storage cavity 442, facilitating the passage of the second retaining ring 434 through the retaining block 445. At this time, the retaining block 445 and the second retaining ring 434 are engaged, making the fixing ring 441 and the moving rod 431 fixedly connected as a whole. Then, by rotating the adjusting rod 432, the adjusting rod 432 moves within the inner cavity of the moving rod 431, causing the second retaining ring... 434 and 445 are tightly engaged, thereby fixing the buckle 3 and the column 1. By expanding the expansion chamber 52, the sealing strip 51 and the side of the glass panel 8 are in close contact. The second spring 57 is taken out by rotating the rear cover 510. At this time, the sliding cover 59 exposes the second connecting hole 58. At this time, the pull rod 56 is pulled to drive the piston block 55 to move in the inner cavity of the pressure cylinder 53. By allowing the outside air to pass through the second connecting hole 58 into the space between the piston block 55 and the first connecting hole 54, the piston block 55 is continuously pulled, forcing the air in the inner cavity of the pressure cylinder 53 into the inner cavity of the expansion chamber 52, causing the outer surface of the sealing strip 51 to expand, so that it can be in close contact with the glass panel 8.
