[0002] With the development of the construction industry, the design of hyperbolic architectural spaces is becoming increasingly common. To achieve the hyperbolic effect, according to traditional construction techniques, curtain wall panels need to be processed into hyperbolic panels separately before installation. However, due to the small warp value, the traditional processing of hyperbolic panels makes bending difficult and cannot guarantee the accuracy of bending. In actual application and installation, due to component size deviations or rebound deformation, the hyperbolic panels may not be installed properly or may even be impossible to install, resulting in waste. Moreover, the construction difficulty, curtain wall cost, and construction period are all significantly increased. Summary of the Invention

The cold bending bracket is installed on the connecting bracket, and the cold bending bracket includes a base plate disposed on the base plate. A second adjusting elongated hole corresponding to the first adjusting elongated hole is provided on the base plate. The cold bending trolley is slidably connected to the cold bending bracket to move along the base plate. The cold bending trolley includes a trolley body and wheels. The trolley body has through holes. The trolley body is installed on the base plate by connecting bolts passing through the first adjusting elongated hole, the second adjusting elongated hole, and the through holes, and then engaging connecting nuts. The wheels are installed on the trolley body and move along the base plate. The cold bending base is located at the end of the connecting bracket away from the end plate and is spaced apart from the cold bending bracket. The cold bending base is connected to the cold bending bracket by adjusting bolts.

[0006] The further technical solution is as follows: the end of the base plate away from the end plate is bent upward at a 90-degree angle to form a connecting plate. The cold bending base includes a main plate and a support plate. The support plate is vertically arranged at one end of the main plate and is arranged opposite to the connecting plate. The connecting plate and the support plate are respectively provided with holes for the two ends of the adjusting bolt to pass through.

[0007] The further technical solution is as follows: the cold-bending base is fixed to the main structure beam of the curtain wall by fixing bolts, and the main board is provided with a slot for the fixing bolts.

[0025] Please see Figures 1 to 4 As shown, Figure 1 This is a structural schematic diagram illustrating a specific application of a cold bending construction device for curtain wall panels provided in an embodiment of the present invention. The cold bending construction device is installed on the main structural beam 20 of the curtain wall and includes a connecting bracket 11, a cold bending bracket 12, a cold bending trolley 13, and a cold bending base 14. The connecting bracket 11 includes a base plate 111, with an end plate 112 vertically disposed at one end of the base plate 111. A first adjusting elongated hole 101 is provided on the base plate 111 along a direction away from the end plate 112. The cold bending bracket 12 is installed on the connecting bracket 11 and includes a base plate 121 disposed on the base plate 111. A second adjusting elongated hole 102 corresponding to the first adjusting elongated hole 101 is provided on the base plate 121. The cold bending trolley 13 is slidably connected to the cold bending bracket 12 to move along the base plate 121. The cold bending trolley 13 includes a trolley body 131 and wheels 132. A through hole 1311 is formed on the trolley body 131. The trolley body 131 is installed on the base plate 121 by connecting bolts 1001 passing through the first adjusting elongated hole 101, the second adjusting elongated hole 102 and the through hole 1311, and then fitted with connecting nuts 1002. The wheels 132 are installed on the trolley body 131 and move along the base plate 121. The cold bending base 14 is located at the end of the connecting bracket 11 away from the end plate 112 and is spaced apart from the cold bending bracket 12. The cold bending base 14 is connected to the cold bending bracket 12 by adjusting bolts 15.

[0026] The end plate 112 is used to connect with the curtain wall panel for cold bending. A first adjusting elongated hole 101 and a second adjusting elongated hole 102, located away from the end plate 112, ensure that the cold bending trolley 131 moves only in a direction perpendicular to the end plate 112, thus preventing forces from other directions from affecting the cold bending effect of the curtain wall panel. The cold bending construction device for curtain wall panels is connected to a cold bending bracket 12 via a cold bending base 14 and adjusting bolts 15. The cold bending bracket 12 is installed on a connecting bracket 11, and a first adjusting elongated hole 101 is provided on the base plate 111 of the connecting bracket 11 in the direction away from the end plate 112. A second adjusting elongated hole 102 is provided on the bottom plate 121 of the cold bending bracket 12 corresponding to the first adjusting elongated hole 101. A cold bending trolley 13 is slidably installed on the cold bending bracket 12 by means of connecting bolts 1001 passing through the second adjusting elongated hole 102, the first adjusting elongated hole 101, and the through hole 1311 of the trolley body 131, so that the trolley can be rotated. The bolt 15 applies a cold bending force and transmits it to the cold bending bracket 12. The cold bending bracket 12 converts the cold bending force into a force perpendicular to the end plate 13 through the cold bending carriage 13, and transmits this force to the connecting bracket 11. This allows for the cold bending operation of the curtain wall panel through the end plate 112, enabling direct cold bending of the curtain wall panel. This allows for simultaneous cold bending and installation operations, eliminating the need to fabricate the curtain wall panel into a hyperbolic panel before installation. The operation is convenient and simple, simplifying the cold bending construction process, effectively shortening the cold bending construction period, and providing high cold bending accuracy. The structure is also simple and easy to maintain.

[0027] Specifically, in this embodiment, the outer surface of the suspended end of the end plate 112 is arc-shaped. Preferably, the upper surface of the substrate 111 has upper serrations 113 with a toothed cross-section. The number of the first adjustment elongated holes 101 can be three, and the three first adjustment elongated holes 101 are distributed parallel to each other on the substrate 111. The number of the second adjustment elongated holes 102 is one, corresponding to the first adjustment elongated hole 101 located in the middle. Connecting bolts 1001 can be inserted into the first adjustment elongated holes 101 located on both sides, and connecting nuts 1002 can be used to make the connection between the connecting bracket 11 and the curtain wall main structure beam 20 more stable. A connecting washer 1003 is provided between the connecting bolt 1001 and the substrate 111. The lower surface of the connecting washer 1003 has lower serrations with a toothed cross-section, and the lower serrations mesh with the upper serrations of the substrate 111.

[0028] Specifically, in this embodiment, the substrate 111 is provided with a first hook groove 114, and the base plate 121 is provided with a second hook groove 122 that engages with the first hook groove 114. The second hook groove 122 engages with the first hook groove 114, so that the cold bending bracket 12 can be detachably installed on the connecting bracket 11. After the cold bending operation is completed, the cold bending bracket 12, the cold bending carriage 13, and the cold bending base 14 can be separated from the connecting bracket 11, allowing the connecting bracket 11 to continue connecting the cold-bent curtain wall panel to the main curtain wall structural beam 20. The cold bending bracket 12, the cold bending carriage 13, and the cold bending base 14 can be reused, saving costs. The number of the first hook grooves 114 can be two, and they are located at both ends of the first adjusting elongated hole 101. Correspondingly, the number of the second hook grooves 122 is also two, and they are located at both ends of the second adjusting elongated hole 102. The first hook grooves 114 and the second hook grooves 122 can be L-shaped.

[0029] Specifically, the end of the base plate 121 furthest from the end plate 112 is bent upwards at a 90-degree angle to form a connecting plate 123. The cold-bent base 14 includes a main plate 141 and a support plate 142. The support plate 142 is vertically disposed at one end of the main plate 141 and opposite to the connecting plate 123. The connecting plate 123 and the support plate 142 are respectively provided with holes for the two ends of the adjusting bolt 15 to pass through. Side plates 144 connected to the main plate 141 may be provided on both sides of the support plate 142.

[0030] Specifically, the cold-bending base 14 is fixed to the main structural beam 20 of the curtain wall by fixing bolts 1004, and the main plate 141 is provided with slots 143 for the fixing bolts 1004. There can be two fixing bolts 1004, and correspondingly, there can also be two slots 143.

[0031] The main structural beam 20 of the curtain wall is provided with embedded parts 21, and one end of the connecting bolt 1001 is fixedly connected to the embedded parts 21.

[0032] Specifically, a washer 124 is provided between the connecting nut 1002 and the trolley body 131.

[0033] Specifically, in this embodiment, four wheels 132 are arranged in pairs on both sides of the carriage body 131 via connecting shafts 1005. The bottom of the carriage body 131 is provided with connecting bearings 1312 for the two ends of the connecting shafts 1005. Wheels 132 are provided on both sides of the carriage body 131 to make the movement of the cold bending carriage 13 more stable and reliable. Specifically, a deep groove ball bearing 133 is coaxially mounted in the center of each wheel 132 for the connecting shafts 1005 to pass through. The deep groove ball bearing 133 reduces friction during power transmission and improves the efficiency of mechanical power transmission through a rolling connection, making the rotation of the wheels 132 more stable.

[0034] In summary, the present invention provides a cold bending construction device for curtain wall panels. This device involves a cold bending base connected to a cold bending bracket via adjusting bolts. The cold bending bracket is mounted on a connecting bracket, and the base plate of the connecting bracket has a first adjusting elongated hole along the direction away from the end plate. The base plate of the cold bending bracket has a second adjusting elongated hole corresponding to the first adjusting elongated hole. A cold bending trolley is slidably mounted on the cold bending bracket via connecting bolts passing through the second adjusting elongated hole, the first adjusting elongated hole, and the through hole. This allows for the application of cold bending force to the adjusting bolts, which is then transmitted to the cold bending trolley. The cold bending bracket converts the cold bending force into a force perpendicular to the end plate through the cold bending trolley, and then transmits this force to the connecting bracket to perform cold bending operations on the curtain wall panels through the end plate. This allows for direct cold bending of the curtain wall panels, enabling simultaneous cold bending and installation operations. There is no need to separately fabricate the curtain wall panels into hyperboloid panels before installing them. The operation is convenient and simple, simplifying the cold bending construction process, effectively shortening the cold bending construction period, ensuring high cold bending accuracy, and having a simple structure that is easy to maintain.
