[0025] Specifically, the installation process of the bridge cap beam formwork support device provided in this embodiment is as follows: first, the support rod 301 is installed into the pier 100 and the support blocks 302 are respectively installed at both ends of the support rod 301, and the sand cylinder 303, the I-beam 304 and the support plate 305 are sequentially installed on the support block 302. After the support plate 305 is installed, the cap beam formwork body 200 can be assembled on the installation plate and the second support assembly 400 can be installed in the circumferential direction of the cap beam formwork body 200. The cap beam formwork body After the assembly of the bridge cap beam formwork 200 is completed, the support frame 404 is rotated respectively to keep the support frame 404 parallel to the corresponding side of the cap beam formwork body 200, and the driving mechanism 402 is operated to adjust the position of the movable block 401 on the support plate 305 until the support beam abuts against the cap beam formwork body 200, so that the position of the cap beam formwork body 200 on the support plate 305 can be fixed and the cap beam formwork body 200 can be supported, ensuring that the position and structure of the cap beam formwork body 200 remain stable during the cap beam casting process.

A slot connected to the through hole is provided on the pier 100, and the support rod 301 has a rib 307 that cooperates with the groove. The support rod 301 is limited to rotate in the through hole through the cooperation of the rib 307 and the groove, so as to avoid the support rod 301 from rotating unexpectedly during the construction process, which causes the bridge cap beam formwork support device to tilt.

[0028] In detail, the support block 302 is provided with a connecting mounting hole and a slot 308, the support rod 301 matches with the mounting hole, and the rib 307 matches with the slot 308. The support block 302 is provided with a mounting hole matching with the support rod 301 so as to facilitate the installation of the support block 302 on the support rod 301, and after the support block 302 is installed on the support rod 301, the rib 307 matches with the slot, thereby limiting the rotation of the support block 302 on the support rod 301 and improving the reliability of the bridge cap beam formwork support device.

[0029] like Figure 2 and Figure 4 As shown, the driving mechanism 402 includes an adjusting screw 405 rotatably arranged on the support plate 305, the axial direction of the adjusting screw 405 is consistent with the moving direction of the movable block 401, and the movable block 401 is provided with a threaded hole matched with the adjusting screw 405. The adjusting screw 405 rotatably arranged on the support plate 305 is matched with the threaded hole on the movable block 401, when the adjusting screw 405 rotates, the movable block 401 moves along the axial direction of the adjusting screw 405, and the axial direction of the adjusting screw 405 is consistent with the moving direction of the movable block 401, so that the position of the movable block 401 can be adjusted, and the moving direction of the movable block 401 can be changed by controlling the rotation direction of the adjusting screw 405, so as to adjust the movable block 401 to a suitable position.

[0030] Specifically, the second support assembly 400 further includes a guide block 406 having a guide groove 407, the length direction of the guide groove 407 is consistent with the moving direction of the movable block 401, and the movable block 401 is movably disposed in the guide groove 407, and the adjusting screw 405 is rotatably disposed in the guide groove 407. The moving direction of the movable block 401 on the support plate 305 is limited by installing the guide block 406 having the guide groove 407 on the support plate 305, so as to prevent the movable block 401 from deviating from the preset direction when moving, and the adjusting screw 405 is rotatably disposed in the guide groove 407, so as to ensure reliable cooperation between the adjusting screw 405 and the movable block 401.

[0031] like Figure 4 As shown, one end of the adjusting screw 405 passes through the guide block 406 and extends out of the guide slot 407, and an adjusting hand wheel 408 is provided at the end of the adjusting screw 405 extending out of the guide slot 407. The adjusting hand wheel 408 is provided at the end of the adjusting screw 405, and the adjusting hand wheel 408 can be operated to conveniently rotate the adjusting screw 405 and move the movable block 401, and the rotating direction and the rotating angle of the adjusting screw 405 can be conveniently controlled by rotating the adjusting screw 405 through the adjusting hand wheel 408, so as to adjust the movable block 401 into place.

[0032] Please combine Figure 1 , Figure 2 and Figure 4 A rotating rod 409 is provided at one end of the support arm 403 away from the movable block 401 , a mounting portion 410 is provided on the support frame 404 , and a connecting hole matching with the rotating rod 409 is provided on the mounting portion 410 . The rotating rod 409 is set at one end of the support arm 403 for connecting with the support frame 404, and the mounting portion 410 on the support frame 404 is provided with a connecting hole matching the rotating rod 409. The rotating rod 409 is inserted into the connecting hole to realize the rotation connection between the support frame 404 and the support arm 403, so that the support frame 404 can rotate smoothly relative to the support arm 403 to adjust the inclination angle of the support frame 404, and at least two push plates 412 are spaced apart on one side of the bracket close to the cap beam formwork body 200. When the support frame 404 is in contact with the cap beam formwork body 200, the push plates 412 are in contact with the surface of the cap beam formwork body 200, ensuring that the structure of the cap beam formwork body 200 remains stable under the support of the support frame 404.

[0033] In detail, the end of the rotating rod 409 has a second threaded portion and the rotating rod 409 is provided with a locking nut 411 matched with the second threaded portion, and the locking nut 411 abuts against the mounting portion 410. The locking nut 411 is used to lock the inclination angle of the support frame 404. The locking nut 411 is rotated to abut against the mounting portion 410 through the cooperation between the locking nut 411 and the second threaded portion, so that the position of the mounting portion 410 can be fixed, so as to prevent the support frame 404 from unexpectedly rotating when it is under pressure during the cap beam casting process, causing the cap beam template body 200 to be stretched open, and ensure that the shape of the cast cap beam meets the preset.

[0034] Please refer to Figure 1 and Figure 2 In order to improve the safety of the bridge cap beam template support device, a fence 500 is further provided on the support plate 305. The fence 500 is arranged around the cap beam template body 200 and is arranged close to the edge of the support plate 305. The fence 500 is used to protect workers who perform cap beam casting operations on the bridge cap beam template support device to prevent workers from accidentally falling from the support plate 305, which is conducive to improving the safety of the bridge cap beam template support device during use.
