Description

Technical Field

[0001] This invention relates to the field of curtain wall panel installation technology, specifically to a connecting component for curtain wall panel installation. Background Technology

[0002] The connection components for curtain wall panel installation play a crucial role in the curtain wall system, undertaking multiple functions such as fixing, support, load transfer, seismic resistance, stress relief, and waterproof sealing. Their function is not only to ensure a stable connection between the curtain wall panels and the building structure, preventing displacement or detachment of the panels due to external loads such as wind pressure and temperature differences, but also to effectively distribute the load and transfer it to the main structure, avoiding structural damage. The structure of these connection components typically includes multiple parts such as connectors, support components, adjusters, sealing components, and shock-absorbing components. Connectors directly connect the curtain wall panels to the building structure using bolts, aluminum alloy plates, etc. Support components provide additional support force, adjusters are used for precise installation, sealing components ensure the curtain wall's waterproofness, and shock-absorbing components effectively absorb vibrations. Their structural principles are based on design requirements for force transmission, thermal expansion adaptability, and waterproof sealing, ensuring the safety, stability, and durability of the curtain wall system during long-term use.

[0003] The connecting assembly for curtain wall panel installation disclosed in authorization announcement number CN207525955U includes a first support frame and a second support frame. The second support frame includes a fixing part for fixing to the curtain wall panel and a connecting plate for connecting the fixing part. One end of the fixing part is fixed to the back bolt of the curtain wall panel through a limiting sleeve, and the other end is fixed to the connecting plate. A buffer spring is provided inside the limiting sleeve. The surface of the connecting plate is parallel to the surface of the curtain wall panel, and the top of the connecting plate is provided with a locking plate for engaging with a T-shaped block. The position where the locking plate engages with the T-shaped block is provided with a stepped groove, which enables rapid installation of the curtain wall panel and prevents the curtain wall panel from being subjected to rigid impact, thus avoiding damage to the curtain wall panel. The above technical solution is comparable to existing curtain wall panel installation and connection technologies and connecting assemblies. The basic operating method is the same: the connecting components connect to the wall and bear the self-weight of the curtain wall panel as well as the force exerted on the curtain wall panel by external forces, thereby effectively distributing the load to the building's frame structure. However, for L-shaped wall areas, the curtain wall panels are installed at the corner of the building, and adjacent curtain wall panels are supported by connecting components on their respective wall surfaces. Because L-shaped wall areas have more complex geometry and construction environment, the sides of adjacent curtain wall panels only contact each other rather than are directly connected. This will lead to insufficient strength at the connection point. Especially when encountering large wind loads, vibrations, or other external impacts, this contact connection cannot provide sufficient resistance, causing the curtain wall panels to shift or loosen, affecting the stability of the curtain wall. Summary of the Invention

[0004] The purpose of this invention is to provide a connecting assembly for installing curtain wall panels. Two T-shaped back brackets are snapped onto the back of a symmetrical L-shaped corner bracket, and two C-shaped support beams are slidably installed on the outer wall of the symmetrical L-shaped corner bracket away from the T-shaped back brackets. The C-shaped support beams support the curtain wall panel. The assembled T-shaped back brackets, symmetrical L-shaped corner brackets, and C-shaped support beams are brought close to the L-shaped wall area, so that the T-shaped back brackets contact the wall. At this time, the elastic self-pushing anti-detachment structure is stressed and connected to the C-shaped support beams. Then, expansion bolts are used to fix the T-shaped back brackets, symmetrical L-shaped corner brackets, and C-shaped support beams at the L-shaped corner wall area. Finally, the bottom edge of the curtain wall panel is supported by the C-shaped support beams, so that two adjacent curtain wall panels can be connected through the symmetrical L-shaped corner brackets and C-shaped support beams, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a connecting assembly for installing curtain wall panels, comprising:

[0006] A symmetrical L-shaped corner bracket is provided, with T-shaped back brackets bolted to both the left and right outer walls of the symmetrical L-shaped corner bracket. A rectangular cutout portion two is provided on one side of the interior of the T-shaped back bracket. C-shaped support beams are slidably installed on both the left and right inner walls of the symmetrical L-shaped corner bracket. A rectangular cutout portion one is provided inside the C-shaped support beam. After the C-shaped support beam and the symmetrical L-shaped corner bracket are slidably assembled, the center points of the rectangular cutout portion one and the rectangular cutout portion two are collinear, and the extension direction of the line connecting the center points of the rectangular cutout portion one and the rectangular cutout portion two is perpendicular to the length direction of the C-shaped support beam. An expansion bolt is installed on the outer wall of the C-shaped support beam away from the T-shaped back bracket, penetrating to the outside of the C-shaped support beam, the symmetrical L-shaped corner bracket, and the T-shaped back bracket. The top and bottom of the C-shaped support beam are provided with U-shaped grooves for the edge of the curtain wall panel to be inserted.

[0007] The elastic self-propelled anti-detachment structure is installed inside the rectangular hollow part of the T-shaped back seat. The elastic self-propelled anti-detachment structure is used to deform when the T-shaped back seat comes into contact with the wall and connect with the C-shaped support beam.

[0008] Preferably, the symmetrical L-shaped corner bracket consists of a square central column, aluminum alloy profile arms, and a right-angle connecting seat. The aluminum alloy profile arms are provided in four configurations, with two aluminum alloy profile arms welded and fixed to one side of the outer wall of the square central column, and the other two aluminum alloy profile arms fixed to the other side of the outer wall of the square central column. The right-angle connecting seat is located at one corner of the square central column and is used to bolt two perpendicular aluminum alloy profile arms.

[0009] Preferably, the T-shaped back support is disposed on one outer wall of the two aluminum alloy profile arms in the same direction, and a plurality of stainless steel back bolts for connecting with the aluminum alloy profile arms are installed on one outer wall of the T-shaped back support.

[0010] Preferably, a gap is provided between the two aluminum alloy profile arms in the same extension direction, and a perforated protrusion is integrally formed on the outer wall of the T-shaped back seat near the aluminum alloy profile arm, the perforated protrusion extending into the interior of the gap.

[0011] Preferably, the C-shaped support beam has a through hole concentric with the perforated protrusion, and one end of the expansion bolt passes through the through hole and the perforated protrusion in sequence.

[0012] Preferably, the top and bottom walls of the C-shaped support beam are provided with ribs for sliding engagement with the aluminum alloy profile arm.

[0013] Preferably, the left and right outer walls of the C-shaped support beam are provided with several column holes extending into the U-shaped groove, and the left and right inner walls of the rectangular hollow part are provided with positioning holes for connecting with the elastic self-pushing anti-detachment structure.

[0014] Preferably, the elastic self-pushing anti-detachment structure includes a U-shaped frame fixed inside the rectangular hollow section, T-shaped pins slidably installed on both sides inside the U-shaped frame, and a central double-sloping trapezoidal platform fixed at the same end of the two T-shaped pins. The central double-sloping trapezoidal platform and the U-shaped frame are elastically connected. Side plates are fixed on both the left and right outer walls of the U-shaped frame, and a protruding plate is slidably installed on one outer wall of the side plate through a guide. A round protrusion is installed on the outer wall of the protrusion away from the central double-sloping trapezoidal platform. The round protrusion and the positioning hole are concentric. A side trapezoidal platform is integrally formed on the outer wall of the protrusion away from the round protrusion. The side trapezoidal platform and the central double-sloping trapezoidal platform are slidably engaged.

[0015] Preferably, the guide is a hollow column sleeve fixed to the outer wall of one side of the side plate and a guide post slidably installed inside the hollow column sleeve, with one end of the guide post fixedly connected to the outer wall of one side of the convex plate.

[0016] Preferably, a helical spring is installed at one end of the surface of the T-shaped pin, one end of the helical spring is fixedly connected to one side of the outer wall of the central double-sloped trapezoidal platform, and the other end of the helical spring is fixedly connected to one side of the outer wall of the U-shaped frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This connecting assembly for curtain wall panel installation utilizes a structure that integrates a T-shaped backrest, symmetrical L-shaped corner brackets, a C-shaped support beam, an elastic self-push anti-detachment structure, and expansion bolts. The combination of the T-shaped backrest and L-shaped corner brackets provides dual longitudinal and lateral support, ensuring the vertical and horizontal stability of the curtain wall panel after installation. The contact between the T-shaped backrest and the wall allows for even distribution of the load across the entire connecting assembly, effectively preventing instability such as tilting or sinking of the curtain wall panel due to gravity or external forces. The C-shaped support beam supports the weight of the curtain wall panel and provides additional stability. The T-shaped backrest is further connected to the C-shaped support beam via the elastic self-push anti-detachment structure. This effectively prevents unnecessary displacement or detachment of the curtain wall panels. At this time, the C-shaped support beam, T-shaped back seat, and L-shaped corner seat form a tight support system, and the stress points of the curtain wall panels are fully distributed, thereby reducing the risk of excessive local load. When two adjacent curtain wall panels are installed in the U-shaped groove at the top of the C-shaped support beam, the two curtain wall panels share a symmetrical L-shaped corner seat. At this time, the support points of the symmetrical L-shaped corner seat evenly distribute the vertical and horizontal loads from the curtain wall panels, avoiding material fatigue or structural damage caused by excessive local load. This allows the entire curtain wall system to effectively withstand external loads, and when subjected to external forces such as wind and earthquakes, the load can be evenly distributed, reducing the risk of single-point overload and enhancing the load-bearing capacity of the connecting components.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1, by Figures 1 to 4 The present invention includes a symmetrical L-shaped corner bracket 1. T-shaped back brackets 3 are bolted to the left and right outer walls of the symmetrical L-shaped corner bracket 1. A rectangular cutout portion 301 is provided on one side of the interior of the T-shaped back bracket 3. C-shaped support beams 2 are slidably installed on the left and right inner walls of the symmetrical L-shaped corner bracket 1. A rectangular cutout portion 202 is provided inside the C-shaped support beam 2. After the C-shaped support beam 2 and the symmetrical L-shaped corner bracket 1 are slidably assembled, the center points of the rectangular cutout portion 202 and the rectangular cutout portion 301 are collinear. The extension direction of the line connecting the center points of the rectangular cutout portion 202 and the rectangular cutout portion 301 is perpendicular to the length direction of the C-shaped support beam 2. An expansion bolt 4 is installed on the outer wall of the C-shaped support beam 2 away from the T-shaped back bracket 3, penetrating to the outside of the C-shaped support beam 2, the symmetrical L-shaped corner bracket 1, and the T-shaped back bracket 3. U-shaped grooves 201 for the edge of the curtain wall panel to be inserted are provided at the top and bottom of the C-shaped support beam 2.

[0030] The elastic self-propelled anti-detachment structure 6 is installed inside the rectangular hollow part 301 of the T-back seat 3. The elastic self-propelled anti-detachment structure 6 is used to deform when the T-back seat 3 comes into contact with the wall and connect with the C-shaped support beam 2.

[0031] Example 2, based on Example 1, is... Figure 5 and Figure 6 The symmetrical L-shaped corner bracket 1 is composed of a square central column 101, aluminum alloy profile arms 102, and a right-angle connecting seat 103. Four aluminum alloy profile arms 102 are provided, two of which are welded and fixed to one side of the outer wall of the square central column 101, and the other two are fixed to the other side of the outer wall of the square central column 101. The right-angle connecting seat 103 is located at one corner of the square central column 101 and is used to bolt two perpendicular aluminum alloy profile arms 102.

[0032] When using the symmetrical L-shaped corner bracket 1, the staff takes out the square central column 101, aluminum alloy profile arm 102, and right-angle connecting seat 103 in sequence. At this time, the two aluminum alloy profile arms 102 are symmetrically welded and fixed to the left and right outer walls of the square central column 101, while the right-angle connecting seat 103 is fixed to the square central column 101 and aluminum alloy profile arm 102 by stainless steel back bolts 5, thus forming a stable L-shaped corner bracket. Its symmetrical structure design can effectively distribute the vertical and horizontal loads from the curtain wall panel. The load will not be concentrated at a certain point, but will be evenly distributed to the wall through the corner bracket, thereby avoiding structural damage or material fatigue caused by excessive local load.

[0033] T-shaped backrests 3 are mounted on one outer wall of two aluminum alloy profile arms 102 in the same direction. Several stainless steel back bolts 5 are installed on one outer wall of the T-shaped backrests 3 for connecting to the aluminum alloy profile arms 102. A gap 104 is provided between the two aluminum alloy profile arms 102 in the same extension direction. A perforated protrusion 302 is integrally formed on the outer wall of the T-shaped backrests 3 near the aluminum alloy profile arms 102, extending into the interior of the gap 104. The symmetrical L-shaped corner brackets 1 are then assembled. After the T-shaped back bracket 3 is fixed, the staff makes it fit between the two aluminum alloy profile arms 102 in the same direction, that is, the perforated protrusion 302 on one side of the outer wall of the T-shaped back bracket 3 is inserted into the gap 104. At this time, the ends of the aluminum alloy profile arms 102 and the T-shaped back bracket 3 coincide and the holes coincide. Finally, the stainless steel back bolts 5 are used to fix the T-shaped back bracket 3 and the aluminum alloy profile arms 102. At this time, the T-shaped back bracket 3 provides strong longitudinal support on the wall, thereby ensuring the stability of the curtain wall panel in the longitudinal direction.

[0034] The C-shaped support beam 2 has a through hole 204 concentric with the perforated protrusion 302 inside. One end of the expansion bolt 4 passes through the through hole 204 and the perforated protrusion 302 in sequence.

[0035] After the C-shaped support beam 2 and the two aluminum alloy profile arms 102 in the same extension direction are slidably assembled, the center points of the first rectangular cutout 202 and the second rectangular cutout 301 are concentric. At this time, the ends of the expansion bolts 4 also pass through the C-shaped support beam 2, the through hole 204, the perforated protruding column 302, and the T-shaped back seat 3 in sequence and are connected to the wall. Due to the large weight of the curtain wall panel, the support of the bottom edge of the curtain wall panel by the C-shaped support beam 2 effectively prevents the curtain wall panel from sagging or tilting, and improves the overall stability.

[0036] Example 3, based on Example 2, by Figure 7 As shown, the top and bottom walls of the C-shaped support beam 2 are provided with ribs for sliding cooperation with the aluminum alloy profile arm 102. The left and right outer walls of the C-shaped support beam 2 are provided with several column holes extending into the U-shaped groove 201. The left and right inner walls of the rectangular hollow part 202 are provided with positioning holes 203 for connecting with the elastic self-pushing anti-detachment structure 6.

[0037] Example 4, based on Example 3, by Figure 8 and Figure 9 The elastic self-propelled anti-detachment structure 6 includes a U-shaped frame 601 fixed inside the rectangular hollow section 301, T-shaped pins 607 slidably installed on both sides inside the U-shaped frame 601, and a central double-sloping trapezoidal platform 608 fixed at the same end of the two T-shaped pins 607. The central double-sloping trapezoidal platform 608 and the U-shaped frame 601 are elastically connected. Side plates 602 are fixed on both the left and right outer walls of the U-shaped frame 601, and a protruding plate 604 is slidably installed on one outer wall of the side plate 602 via a guide. 4. A round protrusion 605 is installed on the outer wall of the side away from the central double-slope trapezoidal platform 608. The round protrusion 605 and the positioning hole 203 are concentric. A side trapezoidal platform 606 is integrally formed on the outer wall of the convex plate 604 away from the round protrusion 605. The side trapezoidal platform 606 and the central double-slope trapezoidal platform 608 are slidably engaged. The guide is a hollow column sleeve fixed on the outer wall of one side of the side plate 602 and a guide post 603 slidably installed inside the hollow column sleeve. One end of the guide post 603 is fixedly connected to the outer wall of one side of the convex plate 604.

[0038] A helical spring 609 is installed at one end of the surface of the T-shaped pin 607. One end of the helical spring 609 is fixedly connected to one outer wall of the central double-sloped trapezoidal platform 608, and the other end of the helical spring 609 is fixedly connected to one outer wall of the U-shaped frame 601. After the symmetrical L-shaped corner bracket 1, C-shaped support beam 2, and T-shaped back bracket 3 are assembled and come into contact with the wall, the T-shaped pin 607 will slide due to the pressure between the T-shaped back bracket 3 and the wall, causing the T-shaped pin 607 and the central double-sloped trapezoidal platform 608 to slide towards the symmetrical L-shaped corner bracket 1. During this process, the helical spring 609 is in a stretched state. Because the central double-sloped trapezoidal platform 608 is subjected to pressure from the T-shaped back bracket 3 and the wall, the T-shaped pin 607 and the central double-sloped trapezoidal platform 608 slide towards the symmetrical L-shaped corner bracket 1. When the pin 607 pushes, the two sides of the double-sloped trapezoidal platform 608 are forced by the side trapezoidal platform 606 to gradually move away from the side plate 602. The side plate 602 and the guide post 603 guide and support the sliding of the expansion bolt 4 until the round protrusion 605 is inserted into the positioning hole 203. The round protrusion 605 and the positioning hole 203 are used to connect the T-shaped back seat 3 and the C-shaped support beam 2, thereby preventing the C-shaped support beam 2 from sliding in the extension direction of the aluminum alloy profile arm 102. Thus, through elasticity, the curtain wall panel can automatically adjust its position when subjected to external force, thereby maintaining its original position and avoiding falling accidents.

[0039] In this embodiment of the application, the first step is to check whether all construction materials and tools are complete, including the symmetrical L-shaped corner bracket 1, C-shaped support beam 2, T-shaped back bracket 3, expansion bolts 4, and the necessary installation tools, such as bolt wrenches, measuring instruments, and levels. Ensure that all components are undamaged, meet design requirements, and confirm that the materials are of acceptable quality. Simultaneously, based on the design drawings and measurement data, mark the installation positions of the symmetrical L-shaped corner bracket 1, C-shaped support beam 2, and T-shaped back bracket 3. During this process, workers must ensure that the placement of each component is reasonable according to the corner shape of the wall and the installation requirements of the curtain wall panels to meet the support requirements of the curtain wall panels. In accordance with the connection requirements, the workers secured the two T-shaped back brackets 3 to the left and right outer walls of the symmetrical L-shaped corner bracket 1, respectively. Stainless steel back bolts 5 were used to securely fasten the symmetrical L-shaped corner bracket 1 and the T-shaped back brackets 3 together. The two C-shaped support beams 2 were then slidably installed on the left and right inner walls of the symmetrical L-shaped corner bracket 1. This process continued until the symmetrical L-shaped corner bracket 1, C-shaped support beams 2, and T-shaped back brackets 3 were fully assembled. Next, the connecting components were fixed to the wall. During fixing, the workers ensured that the T-shaped back brackets 3 were in close contact with the wall and that the installation position met the design requirements, avoiding any deviations. A level was used to ensure its levelness. To prevent instability of subsequent installed components due to imbalance, the elastic self-push anti-detachment structure 6 will make effective contact with the wall and deform during the process, providing a guarantee for the connection and fixation of the T-shaped back bracket 3 and the C-shaped support beam 2. After the symmetrical L-shaped corner bracket 1, the C-shaped support beam 2, and the T-shaped back bracket 3 are connected to each other through the stainless steel back bolt 5 and the elastic self-push anti-detachment structure 6, the symmetrical L-shaped corner bracket 1 is attached to the corner area of ​​the L-shaped wall, and the expansion bolt 4 securely fixes the C-shaped support beam 2, the T-shaped back bracket 3, and the symmetrical L-shaped corner bracket 1 to the wall. At this time, it is still necessary to check again. Check the levelness of the symmetrical L-shaped corner bracket 1 to ensure its accurate position. The installation of the expansion bolts 4 must ensure that each bolt is tightened in place to avoid loosening of the connection due to improper tightening. After installation, check whether the connection of each component is firm and ensure that the T-shaped back bracket 3, the symmetrical L-shaped corner bracket 1 and the C-shaped support beam 2 are not loose or displaced. At this time, the U-shaped grooves 201 at the top and bottom of the C-shaped support beam 2 can support the curtain wall panel, and each curtain wall panel on the C-shaped support beam 2 supports one curtain wall panel. At this time, the adjacent two curtain wall panels can be connected and limited to prevent the curtain wall panels from shifting or falling off under the action of external force.
