[0026] It should be noted that the concepts of "first" and "second" mentioned in this utility model are only used to distinguish between devices, modules or units, and are not used to limit these devices, modules or units to necessarily be different devices, modules or units, nor are they used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0027] To address the issues of poor adaptability and inability to reuse traditional fixed wing plate formwork, please combine... Figures 1 to 3 This application provides an adjustable wing plate formwork, which includes a wing plate formwork connected to the top of the web plate formwork on one side. This application allows the wing plate formwork to be adjusted on the construction site, solving the problem that the wing plate formwork needs to be returned to the factory because its angle is not suitable for bridge wing plate construction, improving the adaptability of the wing plate formwork, and also enabling the reuse of the wing plate formwork.

[0028] It should be noted that box girder construction typically requires the erection of bottom slab formwork, web formwork 200, and wing plate formwork 100. Simultaneously, a formwork truss 300 needs to be erected outside the formwork to support it. In this embodiment, the formwork truss 300 is supported outside the web formwork 200. Adjusting the angle of the wing plate formwork 100 in this application mainly involves adjusting the included angle between the wing plate formwork 100 and the web formwork 200.

[0029] The adjustable wing plate template of this application also includes a template adjustment structure disposed between the wing plate template and the web template. The angle between the wing plate template and the web template is adjusted by the template adjustment structure to achieve the purpose of adjusting the angle of the wing plate template. The template adjustment structure of this embodiment includes an adjustment sleeve 1, a first lead screw 2, and a second lead screw 3. The first lead screw 2 and the second lead screw 3 are respectively inserted at both ends of the adjustment sleeve 1. The end of the first lead screw 2 located outside the adjustment sleeve 1 is used to connect with the wing plate template 100, and the end of the second lead screw 3 located outside the adjustment sleeve 1 is used to connect with the web template 200. Thus, by adjusting the length of the first lead screw 2 and the second lead screw 3 extending out of the adjustment sleeve 1, the angle of the wing plate template 100 relative to the web template 200 is adjusted.

[0030] Specifically, the adjusting sleeve 1 has two threaded sections at both ends, which are respectively threaded to the first lead screw 2 and the second lead screw 3. The two threaded sections of the adjusting sleeve 1 have opposite directions of rotation. By rotating the adjusting sleeve 1, the lead screw can reciprocate along its axial direction, thereby adjusting the length of the lead screw extending out of the adjusting sleeve 1. Furthermore, since the two threaded sections of the adjusting sleeve 1 have opposite directions of rotation, rotating the adjusting sleeve 1 will cause the first lead screw 2 and the second lead screw 3 to move in opposite directions, allowing the first lead screw 2 and the second lead screw 3 to extend or retract into the adjusting sleeve 1 simultaneously.

[0031] Furthermore, the outer side of the adjusting sleeve 1 is provided with an operating rod 11 for rotating the adjusting sleeve 1. The operating rod 11 extends outward along the radial direction of the adjusting sleeve 1 and away from the adjusting sleeve 1. In order to further improve the convenience of operating the operating rod 11, an operating rod 11 is provided on each of its symmetrical sides. The two operating rods 11 can balance the force on the adjusting sleeve 1, so as to better drive the adjusting sleeve 1 to rotate through the operating rod 11.

[0032] The adjustable wing plate template of this application is connected to a first support member 4 at the end of the first lead screw 2 located outside the adjustment sleeve. The first support member 4 can increase the contact area between the top of the first lead screw 2 and the bottom surface of the wing plate template 100, and can disperse the pressure of the first top on the bottom surface of the wing plate template 100, thereby reducing the pressure per unit area, playing a role in protecting the wing plate template 100, and preventing the wing plate template 100 from being partially damaged or deformed.

[0033] Preferably, in this embodiment, the first support member 4 can be made of structural steel or plate, and the first support member 4 extends along the inclined direction of the wing plate template 100. Multiple sets of first support members 4, adjusting sleeves 1, and lead screws can be arranged side-by-side along the width direction of the box girder construction to improve the support capacity for the wing plate template 100 and ensure the angle adjustment effect of the wing plate template 100. The first support member 4 is also provided with a first connecting seat 41. The end of the first lead screw 2 located outside the adjusting sleeve is hinged to the first connecting seat 41 by bolts, allowing the top end of the first lead screw 2 to rotate relative to the wing plate template 100, facilitating the adjustment of the angle of the wing plate template 100.

[0034] Similarly, a second support member 5 is provided outside the adjusting sleeve 1 for the second lead screw 3. The second support member 5 is installed on the template truss 300 of the web template 200, and extends horizontally from the web template 200 away from the web template 200. In this embodiment, one end of the second support member 5 is supported on the template truss 300, and the other end is suspended, so as to adapt to the installation of the adjusting sleeve 1 and the lead screw matching structure at different positions and meet the needs of adjusting the angle of the wing template 100. A second connecting seat 51 is provided on the second support member 5, and the bottom end of the second lead screw 3 is connected to the second connecting seat 51 by bolts, so that the second lead screw 3 can be supported on the second support member 5.

[0035] Furthermore, since the end of the second support member 5 furthest from the web template 200 is suspended, a reinforcing diagonal brace 7 is provided between the bottom of the second support member 5 and the template truss 300. The reinforcing diagonal brace 7 extends obliquely from the end of the second support member 5 furthest from the web template 200 toward the web template 200 and is supported on the template truss 300. By providing the reinforcing diagonal brace 7, part of the load on the second support member 5 can be transferred to the template truss 300 through the reinforcing diagonal brace 7, thereby achieving load distribution and balance. At the same time, the reinforcing diagonal brace 7, the second support member 5, and the template truss 300 together form a triangular structure, giving the second support member 5 of this application good stability and load-bearing capacity.

[0036] In this embodiment, the second support member 5 is selected from steel profiles or plates of the same specifications as the first support member 4, and the second support member 5 corresponds one-to-one with the first support member 4.

[0037] In addition, a third support 6 is provided between the first support 4 and the second support 5 to connect the two. The third support 6 is set parallel to and close to the web template 200. The second support 5 and the third support 6 are vertically connected to ensure that the second support 5 can extend in a direction perpendicular to the web template 200. The first support 4 and the third support 6 are hinged so that the angle between the wing template 100 and the web template 200 can be adjusted by adjusting the angle between the first support 4 and the third support 6, and the adjustment is highly stable.

[0038] Similarly, the third support member 6 is made of the same type of steel or plate as the first support member 4 and the second support member 5, and the third support member 6 is connected to the first support member 4 and the second support member 5 in a one-to-one correspondence.

[0039] In this embodiment, multiple sets of adjusting sleeves 1, a first lead screw 2, and a second lead screw 3 are also provided along the extending direction of the first support member 4 and the second support member 5 to improve the adjustment stability of the wing plate template 100.

[0040] Therefore, when adjusting the angle of the wing plate template 100, the second support member 5, the second lead rod 3, the adjusting sleeve 1, the first lead rod 2, the third support member 6, and the first support member 4 are first installed on the template truss 300. A reinforcing diagonal brace 7 is installed between the second support member 5 and the template truss 300 to ensure the stability of the second support member 5, thereby ensuring the stability of the entire adjustable wing plate template. After the adjustable wing plate template is installed, according to the dimensions of the bridge wing plate, the adjusting sleeve 1 is turned using the operating lever 11 to move the lead rod up and down to adjust the angle of the wing plate template 100 to match the designed bridge wing plate angle. The wing plate template 100 is then installed and fixed onto the first support member 4 for subsequent construction. After construction is completed, the wing plate template 100 is removed and transported to the next construction site, and the above steps are repeated for reuse.

[0041] In summary, the adjustable wing plate formwork of this application uses threaded rods instead of fixed-length steel sections, thereby adjusting the angle of the wing plate formwork 100 by changing the length of the supporting wing plate formwork 100, making it suitable for construction of wing plates at different angles. Furthermore, the adjustable wing plate formwork of this application is detachable and reusable, with high turnover rate, efficient installation and dismantling, and simple operation, thus improving the reuse rate of the wing plate formwork 100.

[0042] The above description is only a partial embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
