Description

Technical Field

[0001] This application relates to the field of curtain wall installation technology, and in particular to a connection structure between curtain wall mullions and beams. Background Technology

[0002] A curtain wall is a building envelope or decorative structure that does not bear the main structural function. It consists of panels and a supporting structural system. In curtain wall design, columns and beams are the main supporting structures. They need to be connected together in a reliable structural manner to withstand external forces such as wind loads and earthquakes from all directions, while also ensuring the stability and durability of the structure.

[0003] In existing technologies, mechanical connection structures are commonly used to connect curtain wall mullions and beams. These mechanical connection structures include connectors and sealing plates. The connectors include at least one set of connecting angle aluminum members. Multiple connecting holes are provided on both the vertical and horizontal sections of the connecting angle aluminum members. Multiple mounting holes are provided at the connection point between the curtain wall mullion and the beam, with the number of mounting holes matching the number of connecting holes on the vertical section of the connecting angle aluminum members. All mounting holes are horizontally positioned. The sealing plate is placed between the curtain wall mullion and the connecting angle aluminum members. During the installation of the curtain wall mullion and beam, firstly, the connecting angle aluminum members are vertically aligned... The connecting holes of the bracket are aligned with the mounting holes on the curtain wall mullions. Screws are then passed through the connecting holes and mounting holes in sequence and connected to the vertical part of the connecting angle aluminum and the mullion screws to achieve the installation connection between the connecting angle aluminum and the curtain wall mullion. Then, the horizontal beam is placed on the horizontal part of the connecting angle aluminum on the side of two adjacent curtain wall mullions that are close to each other, so that the end of the horizontal beam abuts against the side wall of the mullion. Bolts are then passed through the connecting holes of the horizontal beam and the horizontal part of the connecting angle aluminum in sequence and tightened with nuts to achieve the connection of the horizontal beam to the connecting angle aluminum, thereby achieving the fixed connection between the curtain wall mullion and the horizontal beam.

[0004] Regarding the aforementioned technologies, the inventors believe that the connection method, which involves the horizontal beam abutting against two adjacent curtain wall columns and using connecting angle aluminum to connect to both the curtain wall columns and the horizontal beam, and using the horizontal part of the connecting angle aluminum to support the horizontal beam, is prone to problems such as insecure connection and loosening, thus affecting the connection stability between the curtain wall columns and the horizontal beam. Summary of the Invention

[0005] To improve the connection stability between curtain wall mullions and beams, this application provides a connection structure for curtain wall mullions and beams.

[0006] The technical solution for the connection structure between curtain wall mullions and beams provided in this application is as follows:

[0007] A connection structure for curtain wall mullions and beams includes mullions, beams, and connecting components;

[0008] A set of slots is provided on the side wall of the column near the curtain wall, and the slots are arranged along the length of the column.

[0009] The connecting component includes a first connector and a second connector. The first connector is fixedly connected to the column, and the second connector is fixedly connected to the crossbeam. When the crossbeam is installed on the column, the first connector and the second connector are engaged.

[0010] The first connector includes a connecting plate, two first engaging plates, and a support plate. The connecting plate is fixedly connected to the column. The first engaging plates are fixedly connected to the side wall of the connecting plate away from the column, and the two first engaging plates are arranged facing each other. The support plate is fixedly connected between the two first engaging plates, and the support plate is arranged horizontally.

[0011] The second connector includes a mounting plate, two second engaging plates, and an engaging plate. The mounting plate is fixedly connected to the crossbeam, and the crossbeam is located in the engaging cavity formed by the two second engaging plates and the mounting plate. The second engaging plates are fixedly connected to the mounting plate, and the two second engaging plates are parallel to the first engaging plates. The engaging plate is fixedly connected between the two second engaging plates, and the engaging plate is parallel to the support plate and engages with the support plate. When the engaging plate engages with the support plate, the surfaces of one first engaging plate and one second engaging plate are in contact.

[0012] By adopting the above technical solution, the first connector is first installed on the column and a stable connection between the first connector and the column is ensured. Then, the second connector, which is fixedly connected to one end of the crossbeam, is placed between the two first locking plates, and force is applied to the second connector to insert it into the locking cavity formed by the two first locking plates and the support plate along the length direction of the first locking plates. The force is applied to the second connector until the second locking plate abuts against the first locking plate and the meshing plate locks with the support plate, so that the meshing plate can no longer move downward. At this point, the force is stopped, and a firm locking connection between the first connector and the second connector is achieved, thereby realizing a stable connection between the column and the crossbeam. This is beneficial to improving the connection stability between the column and the crossbeam. At the same time, the locking connection method also facilitates the quick disassembly and maintenance of the connecting components.

[0013] Preferably, each of the two first locking plates has a locking groove on the side wall of the side that is close to each other. The locking groove is arranged longitudinally. A locking block is fixedly connected to the side wall of the two second locking plates that is far from each other. The locking block is installed in the locking groove.

[0014] By adopting the above technical solution, the locking block drives the second locking plate to slide along the length of the locking groove into the locking cavity formed by the two first locking plates and the support plate, thereby realizing the quick insertion of the second connector and the first connector. At the same time, the locking groove and the second connector are locked together, which also helps to improve the connection stability between the second connector and the first connector.

[0015] Preferably, the top wall of the support plate is provided with an engagement groove, the engagement groove extends toward the first engaging plate, and the bottom wall of the engagement plate is provided with an engagement block that engages with the engagement groove.

[0016] By adopting the above technical solution, the meshing block and the meshing groove are firmly engaged, which causes the bottom wall of the meshing plate to fully abut against the top wall of the support plate, making it easy to achieve secondary fastening of the first connecting member and the second connecting member, and helping to ensure the stable connection between the first connecting member and the second connecting member.

[0017] Preferably, it further includes a support assembly, which includes a support frame located directly below the connecting plate and the support plate, and is fixedly connected to the connecting plate and the support plate.

[0018] By adopting the above technical solution, the support components are designed to provide stable support for the connecting components and beams, preventing the ends of the connecting components or beams from slipping off, which helps to improve the overall stability of the connection structure between the curtain wall columns and beams.

[0019] Preferably, an extension plate is fixedly connected to the side of the connecting plate near the curtain wall. The extension plate is set perpendicular to the connecting plate, and a locking block that engages with the locking slot is also provided on the side of the extension plate away from the connecting plate.

[0020] By adopting the above technical solution, the card block and the card slot are engaged, which facilitates a secondary restriction on the position of the mounting plate on the column, and helps to further improve the connection stability between the connecting plate and the extension plate and the column.

[0021] The extension plate is also provided with a mounting bracket, which includes an integrally formed vertical part and a horizontal part. The horizontal part is respectively set perpendicular to the vertical part and the extension plate and forms an upward opening.

[0022] By adopting the above technical solution, the installation frame is designed to facilitate the support or installation of the curtain wall in conjunction with the columns, thereby improving the installation efficiency of the curtain wall.

[0023] Preferably, a lifting ring is also provided on the top wall of the mounting plate.

[0024] By adopting the above technical solution, the lifting rings facilitate the hoisting of the crossbeams, thereby improving the installation efficiency of the crossbeams.

[0025] Preferably, a sealing gasket is provided between the connecting plate and the column.

[0026] By adopting the above technical solution, the sealing gasket can improve the sealing performance between the column and the connecting plate, and to a certain extent prevent impurities or rainwater from falling into the gap between the column and the connecting plate, thus affecting the stable connection between the column and the connecting plate.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The connection structure between the curtain wall mullions and beams is designed to achieve a stable connection between the mullions and beams through the secure snap-fit ​​of the first connector and the second connector. This helps to improve the connection stability between the mullions and beams. At the same time, the snap-fit ​​connection method also facilitates the quick disassembly and maintenance of the connection components.

[0029] 2. The support components are designed to provide stable support for the connecting components and beams, preventing the ends of the connecting components or beams from slipping off, and thus improving the overall stability of the connection structure between the curtain wall mullions and beams.

[0030] 3.
