Description

Technical Field

[0001] This invention relates to the field of building component technology, and more specifically to a curtain wall connection structure. Background Technology

[0002] Prefabricated steel structure buildings: Prefabricated buildings are constructed with steel components as their structural system. To qualify as a prefabricated steel structure building, the steel structure, enclosure system, equipment and pipeline system, and interior decoration system must be harmoniously integrated. While traditional steel structure buildings use steel as the building's framework and new thermally insulated lightweight steel frame panels as the enclosure structure, prefabricated steel structure buildings combine these two construction methods. Since the lightweight steel frame panels are prefabricated and installed in a factory, the panels only need to be transported to the construction site and connected using welding, bolts, etc. Currently, prefabricated steel structures are widely used in industrial plants, public buildings, coal conveyor bridges, and rail transit systems.

[0003] In the assembly process of prefabricated steel structures, I-shaped horizontal beams and U-shaped vertical beams are used for assembly. The connecting parts are usually bolted together. Since the horizontal beams are installed on the outside of the vertical beams, support plates are usually welded to the outside of the vertical beams for pre-installation and positioning during the connection of the horizontal and vertical beams to facilitate the installation of the horizontal beams. During installation, workers need to use tools to connect each horizontal beam to the vertical beam in sequence by bolting. Although the assembly process is simple, the steps are cumbersome. When bolting the horizontal beams to the vertical beams embedded in the concrete wall, the length of the horizontal beams extending outside the concrete wall is limited to ensure the stability of the vertical beams. There is insufficient space for workers to tighten the bolts during installation, which increases the assembly difficulty. Summary of the Invention

[0025] Preferably, the support plate is provided with a sealing gasket, and the sealing gasket is coaxial with the connection port.

[0026] In summary, the present invention has the following main beneficial effects:

[0027] By setting up vertical beams, during application, workers can embed the vertical beams in the concrete wall. Two rings located within the horizontal bars can be moved using a movable component. The synchronous, distancing movement of the two rings allows the bolt to rotate. Simultaneously, the bolt rotates and moves into the connection port until it is threaded into the connection port, securing the support plate to the vertical beam. This achieves the purpose of fixing the horizontal beam welded or inserted onto the support plate to the vertical beam. A horizontal beam is inserted between the support plates on every two adjacent vertical beams in the concrete wall to ensure the stability of the horizontal beam. When the movable component moves the rings, the positioning component can also move the positioning rod. During the ring movement, grease is squeezed into the positioning port by the force of the ring movement. As the grease increases in the positioning port, it causes the positioning rod to move. Using the grease to force the positioning rod into the positioning port, the support plate placed on the vertical beam can be positioned. That is, when the ring moves, it first uses the grease to move the positioning rod and then positions the support plate onto the vertical beam through the positioning port. Finally, the bolt is rotated and moved to thread-connect the bolt to the connection port. This design ensures that the support plate will not shift during bolt connection, preventing misalignment and connection failure. When the bolt moves to the preset position, some grease in the vertical beam is delivered to the connection port as the ring moves. The grease in the vertical beam soaks the various components and guides the grease to the connection port, providing grease protection for the bolts and components in the vertical beam. Multiple support plates cover the vertical beam to form a seal, and the grease isolates the components and bolts inside the vertical beam from external air. This not only provides good rust prevention but also lubricates the bolts and other components. Furthermore, the connection can be completed using only moving parts. Even with limited operating space after the support plates are covered on the vertical beam, the stability of the connection is guaranteed. Compared to existing technologies, this application solves the problem of requiring operators to use tools to sequentially fasten each crossbeam to the vertical beam with bolts, which, while simple, is cumbersome. It reduces assembly difficulty, enhances connection stability, and provides stable continuity after connection. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] refer to Figures 1-10 A curtain wall connection structure, comprising:

[0046] Vertical beam 100 embedded in the wall;

[0047] Support plates 101 are distributed on the four sides of the vertical beam 100;

[0048] A crossbeam 102 connected to the support plate 101;

[0049] A horizontal bar 103 is installed inside the vertical beam 100, and two rings 104 are provided inside the horizontal bar 103;

[0050] Multiple connection ports 105 are provided on the support plate 101. The connection ports 105 are provided on the side of the support plate 101 near the vertical beam 100. The vertical beam 100 is provided with bolts 106 corresponding to the connection ports 105.

[0051] Multiple positioning holes 107 are provided on the support plate 101, and positioning rods 108 adapted to the positioning holes 107 are provided on the vertical beam 100.

[0052] A movable component located between the vertical beam 100 and the horizontal bar 103 is used to move two ring bodies 104. The two ring bodies 104 move away from each other and move synchronously. When the ring body 104 moves to a preset position, it can rotate the bolt 106 and move the bolt 106 into the connection port 105 to be threadedly connected to the connection port 105.

[0053] A positioning component located between the ring body 104 and the positioning rod 108 is used to move the position of the positioning rod 108 when the ring body 104 moves to a preset position. The positioning rod 108 moves and is inserted into the positioning port 107. The positioning rod 108 moves before the bolt 106.

[0054] The vertical beam 100 is filled with grease. When the moving part moves the ring 104 to the preset position, it can also deliver a portion of the grease to the connection port 105. The positioning part can use the grease to move the positioning rod 108.

[0055] By setting up the vertical beam 100, during application, the operator can embed the vertical beam 100 in the concrete wall. The portion of the vertical beam 100 extending out of the wall provides the necessary space for the installation of the support plate 101. The operator can weld the horizontal beam 102 to the support plate 101, or place the support plate 101 on the vertical beam 100 and then use a moving component to move the position of the ring 104. The movement of the ring 104 allows multiple bolts 106 located in the vertical beam 100 to be threaded into the connection port 105, after which the horizontal beam 102 is inserted into the support plate 101. Specifically, the operator can use a moving component to move two rings 104 located in the horizontal bar 103. The synchronous movement of the two rings 104, moving away from each other, allows the bolts 106 to rotate. As the bolts 106 rotate... Simultaneously, it can also move into the connection port 105 until the bolt 106 is threadedly connected to the connection port 105 and the support plate 101 is fastened to the vertical beam 100. This achieves the purpose of connecting the support plate 101 to the vertical beam 100, thereby fixing the crossbeam 102 welded or inserted onto the support plate 101 to the vertical beam 100. The crossbeam 102 is inserted between the support plates 101 on every two adjacent vertical beams 100 on the concrete wall to ensure the stability of the crossbeam 102. When the moving part moves the ring 104, the positioning part can also move the position of the positioning rod 108. When the ring 104 moves, the grease is squeezed into the positioning port 107 by the force of the ring 104 moving. As the grease increases in the positioning port 107, it can cause the positioning rod 108 to generate The movement of the ring 104, using grease to force the positioning rod 108 into the positioning port 107, positions the support plate 101 placed on the vertical beam 100. Specifically, the ring 104, upon movement, first uses grease to move the positioning rod 108 and then positions the support plate 101 onto the vertical beam 100 through the positioning port 107. Then, the bolt 106 is rotated and moved, threading it into the connection port 105. This ensures that the support plate 101 does not shift during bolt 106 connection, preventing misalignment and connection failure. When the bolt 106 moves to the preset position, with the movement of the ring 104, some grease in the vertical beam 100 is also delivered to the connection port 105, allowing the grease in the vertical beam 100 to soak and clean the internal components. By guiding grease into the connection port 105, the bolts 106 and components in the vertical beam 100 can be protected against corrosion. Multiple support plates 101 cover the vertical beam 100, forming a seal. The grease further isolates the components inside the vertical beam 100 and the bolts 106 from external air contact, providing not only good rust prevention but also lubrication for the bolts 106 and other components. Furthermore, the connection can be completed using only moving parts. Even with limited operating space after the support plates 101 are placed on the vertical beam 100, the stability of the connection is guaranteed. Compared to existing technologies, this application solves the problem of requiring operators to use tools to sequentially fasten each crossbeam 102 to the vertical beam 100 using bolts 106.While the assembly process is simple, the numerous steps involved reduce the assembly difficulty, enhance the stability of the connection, and provide consistent stability after connection.

[0056] As a further embodiment of the present invention, it also includes a positioning rectangular tube 200 disposed on the vertical beam 100, a positioning rectangular groove 201 adapted to the positioning rectangular tube 200 is provided on one side of the support plate 101, a connection port 105 and a positioning port 107 are provided in the positioning rectangular groove 201, and a connection opening 202 penetrating the vertical beam 100 and the positioning rectangular tube 200 is provided on the four sides of the interior of the vertical beam 100, and a bolt 106 is disposed in the connection opening 202.

[0057] The bolt 106 includes a rotating section 203 rotatably connected to the connection opening 202, a threaded section 204 slidably connected to the rotating section 203 and threadedly connected to the connection opening 202, and a nut 205 adapted to the threaded section 204 is provided in the connection port 105.

[0058] By setting a positioning rectangular tube 200 and opening a positioning rectangular groove 201 on the support plate 101 that is compatible with the positioning rectangular tube 200, it is convenient for operators to quickly and initially position the support plate 101 when placing it on the vertical beam 100. In application, when the ring body 104 moves, it can make the rotating section 203 rotate. The rotation of the rotating section 203 can drive the threaded section 204 to rotate. The rotation of the threaded section 204 can use the force of the thread to make the threaded section 204 gradually move into the connection port 105. After the threaded section 204 is threadedly connected to the nut 205 in the connection port 105, when the threaded section 204 moves into the connection port 105 to the preset position, the rotating section 203 limits it. When the threaded section 204 and the nut 205 are tightened, the position of the nut 205 can be pulled so that the support plate 101 can be tightly attached to the vertical beam 100, so as to achieve the purpose of fastening the support plate 101 to the vertical beam 100.

[0059] As a further embodiment of the present invention, the movable component includes a plurality of slides 300 formed on the outer side wall of the crossbar 103, a connecting rod 301 extending through the slides 300 into the crossbar 103 is connected to the inner side wall of the ring body 104, a movable ring 302 is connected to the connecting rod 301, a lead screw 303 is rotatably connected inside the vertical beam 100, the movable ring 302 is threadedly connected to the lead screw 303, and one end of the lead screw 303 passes through the vertical beam 100 and is connected to a hexagonal block;

[0060] By setting up a hexagonal block, during application, the operator can use a tool to rotate the hexagonal block, thereby rotating the lead screw 303. The lead screw 303 can use the force of the thread to move the moving ring 302. The moving ring 302 can move the ring body 104 through the connecting rod 301, thus achieving the purpose of using only the rotation of the lead screw 303 to make the two ring bodies 104 move synchronously and away from each other, simplifying the installation steps. In addition, the grease filled in the vertical beam 100 can prevent rust and lubricate the lead screw 303, ensuring the service life of the lead screw 303.

[0061] As a further embodiment of the present invention, the moving component also includes a rack 304 disposed on the ring 104, and a gear 305 meshing with the rack 304 is disposed on the rotating section 203;

[0062] By setting the rack 304, the rack 304 can move when the ring 104 moves, and the movement of the rack 304 can make the gear 305 rotate, thereby achieving the purpose of making the rotating section 203 rotate.

[0063] As a further embodiment of the present invention, a conveying port 400 is provided at one end of the rotating section 203, and an oil injection port 401 communicating with the conveying port 400 is provided on the threaded section 204. A bracket 402 is provided inside the oil injection port 401, and a first piston 403 adapted to the conveying port 400 is provided on the top of the bracket 402. A second piston 404 is connected to one side of the ring body 104, and a first conveying pipe 405 slidably connected to the second piston 404 and rotatably connected to the conveying port 400 is provided. Dividing pipes 406 are respectively connected to the two sides inside the vertical beam 100, and the first conveying pipe 405 extends into the dividing pipe 406.

[0064] By setting the first piston 403, in the initial state, the first piston 403 is located inside the delivery port 400, which can close the delivery port 400. When the ring body 104 moves, causing the rack 304 to drive the gear 305 to rotate, causing the connection port 105 on the threaded section 204 to rotate, the first piston 403 leaves the delivery port 400, the delivery port 400 is opened, and the grease in the vertical beam 100 can flow into the downward-facing connection port 105. When the ring body 104 continues to move, causing the second piston 404 to move into the separator tube 406, the grease in the separator tube 406 can be compressed into the first delivery tube 405, and guided by the first delivery tube 405, the grease can be delivered to the remaining unfilled connection port 105. The grease can flow to the bolt 106 and nut 205, thereby achieving... When the threaded section 204 moves to the preset position, grease can flow into the connection port 105 to lubricate and prevent rust and corrosion of the threaded section 204 and nut 205 in the connection port 105. This enhances the sustainable usability of the threaded section 204 and nut 205 and avoids the problem of air contact with the threaded section 204 and nut 205 causing rust and affecting subsequent stability. At the same time, when the second piston 404 moves to fill the connection port 105 with grease, the air inside is gradually compressed and replaced by grease. That is, the connection port 105 is in a positive pressure state. The force generated by this positive pressure can make the support plate 101 move away from the vertical beam 100, while the threaded section 204 makes the nut 205 and support plate 101 move towards the vertical beam 100. The interaction of the two forces can further enhance the stability after connection.

[0065] As a further embodiment of the present invention, the positioning component includes a connecting groove 500 formed on the positioning rectangular tube 200, a positioning rod 108 slidably connected in the connecting groove 500, a third piston 501 slidably sleeved inside the crossbar 103 connected to one side of the moving ring 302, a second conveying pipe 502 connected to the crossbar 103, one end of the second conveying pipe 502 communicating with the interior of the crossbar 103, and the other end of the crossbar 103 extending through the crossbar 103, the partition tube 406 and the vertical beam 100 to the connecting groove 500, and a flow port 503 communicating with the interior of the crossbar 103 is formed on the outer side wall of the crossbar 103, the flow port 503 being located between the second conveying pipe 502 and the third piston 501;

[0066] By setting the third piston 501, during application, the grease in the vertical beam 100 can flow into the cavity between the third piston 501 and the second delivery pipe 502 through the flow port 503. The movement of the ring body 104 can drive the third piston 501 to move. When the third piston 501 moves past the flow port 503, it can squeeze the grease into the second delivery pipe 502. The grease can be guided into the connecting groove 500 through the second delivery pipe 502. The grease gradually fills the connecting groove 500, which can achieve the purpose of moving the positioning rod 108, thereby improving the stability when the support plate 101 is connected to the vertical beam 100.

[0067] As a further embodiment of the present invention, a groove 306 is provided on the side of the rack 304 near the ring 104, and a slider 307 is connected to the ring 104 and slidably connected to the groove 306.

[0068] By setting the slide groove 306, the rack 304 meshes with the gear 305 in the initial state. The rotation of the rotating section 203 generates a large force to make the threaded section 204 rotate and move. The movement of the ring body 104 allows the slider 307 to slide a certain distance in the slide groove 306 to the limit position. Only after the continued movement of the ring body 104 can the rack 304 follow suit. That is, the ring body 104 will first drive the third piston 501 to move to the preset position before the rack 304 can move, so that the grease can pass through the second conveyor first. The feed tube 502 enters the connecting groove 500, allowing the positioning rod 108 to be inserted into the positioning port 107 to position the support plate 101. The moving rack 304 causes the threaded section 204 to rotate and move into the connecting port 105 to be threadedly connected to the nut 205. This ensures that the nut 205 and the threaded section 204 are perpendicularly aligned before the threaded section 204 is connected, avoiding connection failure. This eliminates the need for operators to constantly try to connect, thereby increasing connection speed and simplifying the operation steps.

[0069] As a further embodiment of the present invention, a return port 504 is provided on one side of the third piston 501, a baffle 505 is provided inside the return port 504, and a first spring 506 is connected between the baffle 505 and the return port 504.

[0070] By setting the return port 504, the baffle 505 and the first spring 506 can close the return port 504. When the third piston 501 initially moves, the first spring 506 restricts the position of the baffle 505 to close the return port 504, so that the third piston 501 can push the grease through the second delivery pipe 502 into the connecting groove 500. When the ring 104 continues to move to make the rack 304 move and the connecting groove 500 is filled with enough grease, the force required for the third piston 501 to move increases. The baffle 505 moves and the second spring stretches to open the return port 504, so that the grease can overflow through the return port 504, avoiding the problem of grease affecting the continued movement of the ring 104.

[0071] As a further embodiment of the present invention, a tapered opening 507 is provided on the side wall of the positioning opening 107;

[0072] By setting the tapered opening 507, when the operator places the support plate 101 on the positioning rectangular tube 200, there may be a slight misalignment. When the positioning rod 108 moves, it will first contact the tapered opening 507 and squeeze the tapered opening 507. When the positioning rod 108 continues to move, the misaligned support plate 101 can be straightened, ensuring that the nut 205 and the threaded section 204 can be coaxial when the threaded section 204 is connected to the nut 205 later.

[0073] As a further embodiment of the present invention, a sealing gasket 206 is provided on the support plate 101, and the sealing gasket 206 is coaxial with the connection port 105.

[0074] By setting a sealing washer 206, after the threaded section 204 is tightened with the nut 205, the sealing washer 206 can enhance the sealing between the support plate 101 and the vertical beam 100.

[0075] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
