For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0044] See also Figure 1-8As shown, an embodiment of the present application provides a bridge flange area support frame (which may be referred to as a "support frame"), which is mainly used to support the formwork system of the bridge flange area. As the formwork system of the flange area, it mainly includes an outer straight area and an inner arc angle area. The support frame mainly includes a bottom bracket 100, multiple support beams 200, a plurality of first connecting members 300, a plurality of second connecting members 400 and a plurality of support rods 500. The bottom bracket 100 is set up below the flange area, at least covering the formwork system area; the support beam 200 is installed on the bottom bracket 100; the first connecting member 300 is detachably installed on the support beam 200, and the plurality of first connecting members 300 are all distributed below the straight area; the second connecting member 400 is detachably installed on the support beam 200, and the plurality of second connecting members 400 are all distributed below the arc angle area. The length of the support rod 500 is adjustable, and the multiple support rods 500 are divided into two groups, which are respectively located below the straight area and the arc angle area (i.e., corresponding to the first connecting member 300 and the second connecting member 400, respectively); the lower end of the support rod 500 located in the straight area is detachably connected to the first connecting member 300, and the upper end is supported on the formwork system; the lower end of the support rod 500 located in the arc angle area is detachably connected to the second connecting member 400, and the upper end is supported on the formwork system. The above-mentioned support frame is first arranged on the ground through the bottom bracket 100 as a basic support, and then the support beam 200, connecting members (including the first connecting member 300, the second connecting member 400) and the support rod 500 are arranged on the bottom bracket 100 to provide force support for the formwork system in the beam flange area. The bottom bracket 100, the support beam 200, the connecting members, the support rod 500, and the formwork system are detachably connected, and the construction and installation are simple, the disassembly and transportation are fast, the support is stable, and it can be reused.

[0045] It is understandable that the bottom bracket 100 is generally erected on the foundation below the flange area, flush with the top, and the erection height generally does not exceed the formwork system, mainly playing the role of basic support. The bottom bracket 100 can be a general scaffolding or a steel pipe pole, as long as it can play the role of basic support, so it will not be repeated.

[0046] It is understandable that the number of the support rods 500 is generally required to be equal to the sum of the number of the first connecting members 300 and the second connecting members 400. Of course, the first connecting members 300 and the second connecting members 400 may also exist for backup.

[0047] See also Figure 1 , 2As shown in Figures 3, 4, and 6, in some embodiments, a walking mechanism is also arranged between the bottom bracket 100 and the support beam 200, and the walking mechanism mainly includes a track beam 800 and a roller assembly 220 that cooperate with each other. The track beam 800 is fixedly installed on the bottom bracket 100, and the track beam 800 is arranged along the length direction of the bridge. The roller assembly 220 is fixedly installed below the support beam 200, and the roller assembly 220 and the track beam 800 are slidably matched to realize the walking of the support beam 200 along the length direction of the bridge. By setting up the walking mechanism, the lower support structure of the flange area (the support structure includes the support beam 200 and the part above the support beam 200) can be directly slid and displaced on the track beam 800 to the next stage for reuse after the casting is completed in one stage, thereby realizing the reuse of the support structure of different flange sections of the same bridge. Compared with the existing technology, it does not need to be repeatedly disassembled and transferred, which greatly shortens the construction period and reduces the cost.

[0048] Specific to Figure 2 , 3 In the illustrated embodiment, the roller assembly 220 includes a pair of wheel base plates 221 and rollers 222. The pair of wheel base plates 221 are welded and fixed to the lower portion of the support beam 200, and are arranged parallel and symmetrically to each other. The rollers 222 are rotatably connected to the pair of wheel base plates 221 at both ends.

[0049] Furthermore, a plurality of anti-roll bars 223 are welded between the pair of wheel base plates 221, preferably two anti-roll bars 223, and the two anti-roll bars 223 are distributed on the front and rear sides of the roller 222. Figure 2 A pair of wheel base plates 221 and an anti-roll bar 223 form a slot structure that is buckled on the track beam 800, so that the support beam 200 always remains vertical and stable with the track beam 800, preventing overturning from the front, back, left and right directions.

[0050] See also Figure 5 , 7 As shown, in some embodiments, the support rod 500 includes at least one steel pipe upright pole 510 and a top support 520, and the top support 520 is connected to the upper end of the steel pipe upright pole 510 by threaded matching, which is convenient for adjusting the height of the top support 520, enhancing adaptability, and is convenient for disassembly and replacement. The lower end of the steel pipe upright pole 510 has a screw rod 511. When the support rod 500 is not long enough in the height direction, multiple steel pipe upright poles 510 can be connected end to end and threadedly connected by the screw rod 511 to adjust and adapt to different height requirements. Of course, the length of a single steel pipe upright pole 510 can also be adjusted, or steel pipe upright poles 510 of various length specifications can be prepared for standby, such as 30cm, 50cm, 70cm, 100cm and other lengths for batch production for installation at different heights.

[0051] It should be noted that the formwork system of the flange area adopts the formwork system in the prior art, which mainly includes a formwork, a wooden square 700 and a steel pipe 600.

The detachable connection is achieved by the matching of the latch teeth 210 and the through holes.

[0053] Specifically, two through holes may be provided on each of the first connecting member 300 and the second connecting member 400, so that the connection is more firm and stable.

[0054] Furthermore, a first connecting sleeve 310 is provided on the upper surface of the first connecting member 300 . The first connecting sleeve 310 is perpendicular to the first connecting member 300 and faces upward. The first connecting sleeve 310 is connected to the screw rod 511 by threaded fitting to achieve a detachable connection.

[0055] Furthermore, the first connecting member 300 is a C-shaped structure, which can be buckled on the support beam 200 when connected. Among them, the support beam 200 can be made of H-shaped steel, and the first connecting member 300 can be made of channel steel, which is convenient to obtain.

[0056] See also Figure 6 As shown, in some embodiments, the second connecting member 400 includes a rotating shaft 410 and a second connecting sleeve 420, both ends of the rotating shaft 410 are rotatably connected to the second connecting member 400, the second connecting sleeve 420 is fixedly connected to the middle of the rotating shaft 410, and can rotate at any angle with the rotating shaft 410, and the second connecting sleeve 420 is connected to the screw rod 511 by threaded matching. The second connecting sleeve 420 that rotates at any angle can make the support rod 500 arranged at any angle to support the arc angle area of ​​any arc of the template system, and can be changed in length and angle according to the shape of the arc angle area, and can be reused to adapt to different positions and angles.

[0057] Furthermore, the second connecting member 400 also includes a pin 430, the end of the rotating shaft 410 has a plurality of radially penetrating pin holes 411, and the second connecting member 400 is provided with a socket 401; when the angle of the second connecting sleeve 420 is determined, the pin 430 can be inserted into the socket 401 and the corresponding pin hole 411 at the same time to achieve fixation.

[0058] Furthermore, the second connecting member 400 is an H-shaped structure, and is configured to be buckled on the support beam 200 to enhance stability. The second connecting member 400 can be made of H-shaped steel, which is easy to obtain.

[0059] The construction method of the bridge flange area support frame in the above preferred embodiment mainly includes the following steps:

[0060] S1. Set up a bottom bracket 100 below the flange area and adjust the top of the bottom bracket 100 to be flush.
