[0002] At present, overpass formwork bridges usually use portal formwork piers, which are mainly composed of two vertically arranged square-section piers and a crossbeam on the top of the two piers. Its advantages are flexible layout and large spanning capacity, but its disadvantages are lack of aesthetics and mechanical imbalance. With the rapid development of my country's infrastructure, the current urban building structure is no longer just considered for its use function and safety, and aesthetics has become another important factor in the design of building structures. In recent years, for this type of formwork bridge, people have become increasingly dissatisfied with the appearance of the square piers in front. Since the curved piers have a reasonable stress state and a novel appearance, they are becoming more and more popular.

[0020] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0021] Reference Figure 1-4 The utility model embodiment is a double-column hyperbolic double-beam portal pier column template, which includes: a pier column template 1, which is assembled from a plurality of template shells 2, and the upper and lower ends of the template shells 2 are provided with connecting flanges 201, and the flange hole positions of the two connecting flanges 201 correspond to each other, and the upper surface of the top connecting flange 201 is provided with a positioning plug plate 202, and the positioning plug plate 202 and the connecting flange 201 are integrally formed, and a slot 203 is opened at the bottom end of the bottom connecting flange 201, and a plurality of nuts 3 are welded and fixed on the lower surface of the top connecting flange 201, and the positions of the nuts 3 correspond to the positions of the flange holes, and the flange holes of the bottom connecting flange 201 are provided with bolt limiter components 4 threadedly fixed with the nuts 3;

[0022] The bolt limiting assembly 4 comprises a bolt 401, a spring 402, and two fixing rings 405 symmetrically arranged in the upper and lower parts. A rotating ring 403 is welded to both ends of the spring 402. Slide blocks 404 are provided on the opposite sides of the two rotating rings 403. A sliding groove 406 is provided on the opposite sides of the two fixing rings 405. The outer wall of the sliding block 404 is rotatably connected to the inner wall of the sliding groove 406. The inner walls of the fixing ring 405, the spring 402, and the rotating ring 403 are all slidably connected to the side wall of the bolt 401. The side wall of the bolt 401 is slidably connected to the inner wall of the flange hole. The thread of the bolt 401 is matched with the thread groove of the nut 3. The upper surface of the top fixing ring 405 is welded and fixed to the lower surface of the rotating handle of the bolt 401, and the lower surface of the bottom fixing ring 405 is welded and fixed to the upper surface of the connecting flange 201. By setting the template shell 2, positioning plug plate 202, and slot 203, when the two groups of template shells 2 are assembled, the positioning plug plate 202 of the lower template shell 2 is inserted into the slot 203 of the upper template shell 2, and the two groups of template shells 2 are quickly positioned directly. The flange holes of the two groups of shells are directly calibrated to provide conditions for connection and fixation, thereby improving the installation efficiency; by the bolt limit assembly 4, nut 3, and connecting flange 201, the two groups of template shells 2 are positioned at the same time, and each bolt 401 is inserted into the corresponding flange hole. In the next step, only the bolt 401 needs to be rotated to be threadedly connected with the nut 3. As the bolt 401 is pushed downward, the spring 402 shrinks accordingly. The spring 402 connects the bolt 401 to the connecting flange 201 as a whole through the rotating ring 403 and the fixing ring 405, and cooperates with the nut 3 welded to the connecting flange 201, which not only shortens the installation steps, but also avoids the loss of parts and affects the assembly.

[0023] Working principle: When in use, when assembling the template shell 2, insert the positioning plug plate 202 of the lower template shell 2 into the slot 203 of the upper template shell 2 to directly complete the rapid positioning of the two groups of template shells 2. The flange holes of the two groups of shells are directly calibrated, and each bolt 401 is inserted into the corresponding flange hole. In the next step, just rotate the bolt 401 to threadably connect with the nut 3. As the bolt 401 is pushed downward, the spring 402 shrinks accordingly. The spring 402 connects the bolt 401 to the connecting flange 201 as a whole through the rotating ring 403 and the fixing ring 405, and cooperates with the nut 3 welded to the connecting flange 201, which not only shortens the installation steps, but also avoids the loss of parts and affects the assembly.
