Description

Technical Field

[0001] This invention relates to the field of glass curtain wall installation and construction technology, specifically a point-supported glass curtain wall installation and construction process. Background Technology

[0002] Point-supported glass curtain walls consist of decorative glass panels, connecting components, and supporting structures. They are classified into flat-head and convex-head point-supported glass curtain walls according to their exterior decorative effect, and into glass rib point-supported glass curtain walls, steel structure point-supported glass curtain walls, steel tie rod point-supported glass curtain walls, and steel cable point-supported glass curtain walls according to their supporting structures. The diverse supporting structures can meet the needs of different building structures and decorative effects.

[0003] For example, the Chinese authorized patent with announcement number CN211396169U (an installation structure for a point-supported glass curtain wall) includes two glass panels arranged parallel to the wall surface of the building, a glass rib plate arranged vertically and fixedly connected between the building wall and the glass panels, and a clamp connecting the glass panels and the glass rib plate. The glass rib plate is perpendicular to the glass panels, and the two glass panels are symmetrically distributed along the width center line of the glass rib plate. A gap is provided between the two glass panels. One end of the clamp is provided with a connecting component connecting the two glass panels. The connecting component includes a first fixing plate located on the side of the glass panel away from the glass rib plate, a second fixing plate located on the side of the glass panel closer to the glass rib plate, and a threaded fastener passing through the first fixing plate and threadedly connected to the second fixing plate. The threaded fastener is located within the gap. The other end of the clamp is fixedly connected to the building wall through a pre-embedded part, thereby improving the stability of the glass curtain wall.

[0004] However, the existing point-supported glass curtain walls rely on embedded parts and glass auxiliary plates for auxiliary support during installation. Once fixed, it is inconvenient to adjust the strength of the glass curtain wall to be installed, thus affecting its stability. Therefore, it does not meet the current needs. To address this, we propose a point-supported glass curtain wall installation process. Summary of the Invention

[0005] The purpose of this invention is to provide a point-supported glass curtain wall installation process to solve the problem mentioned in the background art that existing point-supported glass curtain walls rely on embedded parts and glass auxiliary plates for auxiliary support during installation. Once fixed, it is inconvenient to adjust the strength of the glass curtain wall to be installed, thus affecting its stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a point-supported glass curtain wall installation construction process, comprising the following steps:

[0007] Step 1: First, lay out the lines to determine the control points. Connect each pair of horizontal control points with guy lines. The connected guy lines form a net in the air. Mark each intersection with a pen to ensure that the intersections of the guy lines remain unchanged during construction. Then, position, install, and inspect the guy lines and suspension rods. The accuracy of the installation and positioning of the suspension rods directly affects whether the glass can be installed according to the design drawings, and affects the flatness of the glass curtain wall after installation, the width of the sealant joint, and the stability of the glass curtain wall. Therefore, the installation sequence, adjustment accuracy, and prestress value of the suspension rods must be strictly controlled in order to effectively control the installation quality of the glass curtain wall.

[0008] Step Two: Installation follows the principle of top-to-bottom and vertical-to-horizontal installation. For vertical cables, the cable length is increased by 1mm-3mm from the top structure, starting from the top. The cables are in a free state. Adjustments are made after all vertical cables are installed, also from top to bottom, adjusting the suspension rods layer by layer according to the size control unit. For horizontal cables, after the vertical cables are installed and adjusted, connect the horizontal cables. Before installation, the horizontal cables should be increased by 1mm-3mm from the length designed in the drawings, in a free state. Install them from top to bottom, layer by layer according to the control unit. Adjust them in place after all installations are completed. Then, the positioning and adjustment of the suspension rods are carried out. During the installation of the suspension rods, the geometric dimensions of the installation positioning of the rods must be checked. The length dimensions of the front and rear cables must be strictly adjusted according to the dimensions in the drawings to ensure the perpendicularity of the suspension connecting rods to the glass plane. The adjustment is based on the unit control point to verify the center position of each suspension rod, ensuring that the front end of each suspension rod is consistent with the glass plane. The overall flatness error is controlled within <5mm / 3m.

[0009] Step 3: Next, conduct a counterweight test. Since the self-weight load of the glass curtain wall and other loads it bears are transferred to the main support structure through the suspended rod structure, in order to ensure that the deformation of the tie rod system is within the allowable range after the glass is installed, a counterweight test must be conducted on the suspended rod. The counterweight test should be set according to the control unit. The weight of the counterweight is the gravity load generated by the glass on the suspended rod multiplied by a coefficient of 1-1.2. The structural deformation after counterweighting should be less than 2mm. During the counterweight test, the counterweight should be applied gradually. The deformation of the suspended rod should be tested after each addition, until all the counterweights are applied to the suspended rod. The deformation value and the reset status after unloading should be measured and recorded in detail.

[0010] Step 4: Before glass installation, check and verify that the verticality, elevation, beam height, and horizontality of the main steel structure support meet the design requirements. Pay special attention to the re-checking of the installation hole positions. Before installation, the surface and bottom of the steel channel must be locally cleaned with a steel brush. Neoprene rubber pads should be added to the U-shaped steel channel at the bottom of the glass joint at 1 / 4 width from the edge of the glass. Before installation, clean the glass and suction cups. Determine the number of suction cups according to the weight of the glass and the specifications of the suction cups. First, check whether the installation position of the connecting claws is accurate. Assemble the connector and glass on the installation platform, and then install it with the connecting claws. To ensure the airtightness and watertightness of the connector, a torque wrench must be used. Determine the torque according to the specific specifications and dimensions of the connecting system. When installing the glass according to the standard, it should always be suspended on the two connectors.

[0011] Step 5: Then install the auxiliary glass onto the connecting assembly for secondary reinforcement and apply adhesive to fix it in place;

[0012] Step Six: Before applying the sealant, clean the glass and steel channel areas with xylene or industrial ethanol and a clean towel. Seal the gap between the bottom of the glass and the steel channel with foam tape to ensure straightness and leave a clearance of 8mm-12mm for the sealant thickness. Apply protective tape to the areas to be sealed, ensuring the tape and sealant joint are straight. Apply the sealant continuously and evenly. The general order of operation is to seal the horizontal joints first and then the vertical joints. Vertical joints should be sealed from top to bottom. After filling the sealant, check for air bubbles, voids, gaps, and impurities. If any are found, deal with them promptly. When applying sealant the next day, clean the sealant head at the joint and cut off the sealant tail from the previous application to ensure a tight connection between the two sealants. After the glass sealant is applied, quickly remove the tape from the glass. After the glass sealant has cured, clean the inside and outside glass and mark the protective areas.

[0013] It also includes a connecting assembly, on which a first fixing frame is provided, an auxiliary glass is installed inside the first fixing frame, a second fixing frame is provided at the front end of the auxiliary glass, a second placement slot is provided inside the second fixing frame, and the front end face of the auxiliary glass is inserted into the second placement slot.

A first limiting plate is provided at the top and bottom ends of each curtain wall glass piece, and a second limiting plate is provided on both side ends of each curtain wall glass piece. A first placement groove is provided inside the first limiting plate and the second limiting plate, and the curtain wall glass pieces are inserted and connected to the first placement grooves on all four sides.

[0015] Preferably, a fixing block is provided at both the upper and lower ends of the front end face of the curtain wall glass, a first support rod is installed between the fixing blocks, a fixing screw is installed on one side of the fixing block, and a second support rod is installed between the first support rods.

[0016] Preferably, a fixing screw is installed on one side of the first fixing frame and the second fixing frame, and a connecting rod is provided on both end faces of the first fixing frame, and four connecting rods are provided.

[0019] Preferably, the front end of the second fixing frame is provided with a cable tray, the cable tray is provided with cable grooves on all four sides, the front end face of the cable tray is provided with an installation groove, and the cable tray is provided with a rotating rod inside.

[0020] Preferably, both the first and second support rods are provided with placement slots inside, and both the first and second support rods are provided with connection ports at their connection points.

[0021] Preferably, the front end face of the first support rod is provided with a connecting hole, a rotating disk is installed on the connecting hole, and a handle is installed inside the rotating disk.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention provides an extension rod on the connecting rods on both sides of the connecting assembly, allowing the fixing plate to extend to different lengths. This enables the connecting rods to be adjusted according to the curtain wall glass, and the extension rods can be fixed using adjusting screws. Simultaneously, a cable tray is provided on the second fixing frame. The cable tray contains longitudinal and transverse cables that pass through cable grooves for connection and fixation. After the curtain wall glass is installed and all cables are installed, adjustments are made by rotating the rotating plate with a lever, which allows the rotating lever to extend and retract the cables, thereby strengthening the support. This solves the problem that existing point-supported glass curtain walls rely on embedded parts and glass auxiliary plates for auxiliary support during installation, making it inconvenient to adjust the strength of the installed glass curtain wall once fixed, thus affecting its stability.

[0024] 2. By setting an auxiliary glass between the first and second fixed frames, multiple supports are provided after installation using cables, connecting components, and the auxiliary glass, ensuring the stability of the glass after installation and guaranteeing the overall support strength.

[0025] 3. By setting up a first support rod and a second support rod, both of which have placement grooves inside, the cable can be placed inside the placement grooves, which not only protects the cable but also ensures the aesthetics of the glass installation. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Please see Figure 1-6 The present invention provides an embodiment of a point-supported glass curtain wall installation construction process, comprising the following steps:

[0035] Step 1: First, lay out the lines to determine the control points. Connect each pair of horizontal control points with guy lines. The connected guy lines form a net in the air. Mark each intersection with a pen to ensure that the intersections of the guy lines remain unchanged during construction. Then, position, install, and inspect the guy lines and suspension rods. The accuracy of the installation and positioning of the suspension rods directly affects whether the glass can be installed according to the design drawings, and affects the flatness of the glass curtain wall after installation, the width of the sealant joint, and the stability of the glass curtain wall. Therefore, the installation sequence, adjustment accuracy, and prestress value of the suspension rods must be strictly controlled in order to effectively control the installation quality of the glass curtain wall.

[0036] Step Two: Installation follows the principle of top-to-bottom and vertical-to-horizontal installation. For vertical cables, the cable length is increased by 1mm-3mm from the top structure, starting from the top. The cables are in a free state. Adjustments are made after all vertical cables are installed, also from top to bottom, adjusting the suspension rods layer by layer according to the size control unit. For horizontal cables, after the vertical cables are installed and adjusted, connect the horizontal cables. Before installation, the horizontal cables should be increased by 1mm-3mm from the length designed in the drawings, in a free state. Install them from top to bottom, layer by layer according to the control unit. Adjust them in place after all installations are completed. Then, the positioning and adjustment of the suspension rods are carried out. During the installation of the suspension rods, the geometric dimensions of the installation positioning of the rods must be checked. The length dimensions of the front and rear cables must be strictly adjusted according to the dimensions in the drawings to ensure the perpendicularity of the suspension connecting rods to the glass plane. The adjustment is based on the unit control point to verify the center position of each suspension rod, ensuring that the front end of each suspension rod is consistent with the glass plane. The overall flatness error is controlled within <5mm / 3m.

[0037] Step 3: Next, conduct a counterweight test. Since the self-weight load of the glass curtain wall and other loads it bears are transferred to the main support structure through the suspended rod structure, in order to ensure that the deformation of the tie rod system is within the allowable range after the glass is installed, a counterweight test must be conducted on the suspended rod. The counterweight test should be set according to the control unit. The weight of the counterweight is the gravity load generated by the glass on the suspended rod multiplied by a coefficient of 1-1.2. The structural deformation after counterweighting should be less than 2mm. During the counterweight test, the counterweight should be applied gradually. The deformation of the suspended rod should be tested after each addition, until all the counterweights are applied to the suspended rod. The deformation value and the reset status after unloading should be measured and recorded in detail.

[0038] Step 4: Before glass installation, check and verify that the verticality, elevation, beam height, and horizontality of the main steel structure support meet the design requirements. Pay special attention to the re-checking of the installation hole positions. Before installation, the surface and bottom of the steel channel must be locally cleaned with a steel brush. Neoprene rubber pads should be added to the U-shaped steel channel at the bottom of the glass joint at 1 / 4 width from the edge of the glass. Before installation, clean the glass and suction cups. Determine the number of suction cups according to the weight of the glass and the specifications of the suction cups. First, check whether the installation position of the connecting claws is accurate. Assemble the connector and glass on the installation platform, and then install it with the connecting claws. To ensure the airtightness and watertightness of the connector, a torque wrench must be used. Determine the torque according to the specific specifications and dimensions of the connecting system. When installing the glass according to the standard, it should always be suspended on the two connectors.

[0039] Step 5: Then install the auxiliary glass onto the connecting assembly for secondary reinforcement and apply adhesive to fix it in place;

[0040] Step Six: Before applying the sealant, clean the glass and steel channel areas with xylene or industrial ethanol and a clean towel. Seal the gap between the bottom of the glass and the steel channel with foam tape to ensure straightness and leave a clearance of 8mm-12mm for the sealant thickness. Apply protective tape to the areas to be sealed, ensuring the tape and sealant joint are straight. Apply the sealant continuously and evenly. The general order of operation is to seal the horizontal joints first and then the vertical joints. Vertical joints should be sealed from top to bottom. After filling the sealant, check for air bubbles, voids, gaps, and impurities. If any are found, deal with them promptly. When applying sealant the next day, clean the sealant head at the joint and cut off the sealant tail from the previous application to ensure a tight connection between the two sealants. After the glass sealant is applied, quickly remove the tape from the glass. After the glass sealant has cured, clean the inside and outside glass and mark the protective areas.

This solves the problem that existing point-supported glass curtain walls rely on embedded parts and glass auxiliary plates for auxiliary support during installation.
