Description

Technical Field

[0001] This utility model is a bridge pier ice-breaking body installation and positioning device, belonging to the field of bridge pier construction technology. Background Technology

[0002] Icebreakers are facilities installed in seasonally frozen rivers in northern my country to protect bridge piers from impacts by floating ice. Typically, an icebreaker is placed on the ice-facing side, with welded steel reinforcement inside tied to the pier's steel reinforcement and cast as a single unit. The piers protected by icebreakers are generally main piers, located in the water. To meet flood season water level requirements, the icebreaker height is usually designed to be tens of meters or even higher. However, the construction process for bridge piers typically involves tying the steel reinforcement and casting the concrete section by section, making it impossible to cast to the top elevation of the icebreaker in one go. This means the icebreaker needs to be installed in sections in conjunction with the pier formwork. Furthermore, icebreakers are highly susceptible to deformation during processing, installation, and casting, easily causing difficulties in pier formwork construction within the icebreaker area and uncontrolled pier shape. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bridge pier ice-breaking body installation and positioning device.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a bridge pier ice-breaking body installation and positioning device, including a positioning frame 1 with upper and lower layers, an ice-breaking body 5 with upper and lower layers, and a pier body template 6 with upper and lower layers. Positioning ear plates 2 are uniformly welded on the ice-breaking body 5. The positioning frame 1 is provided with a plurality of hook bolts 3, and the hook bolts 3 are connected to the positioning ear plates 2.

[0028] See Figure 1-5 The positioning frame 1 includes a main frame 11, lifting lugs 14, left and right flanges 13, upper and lower flanges 12, and supporting steel 15. The main frame 11 is composed of two steel frame pieces, and the main frame 11 is arranged correspondingly to the frame position of the pier body template 6. The left and right flanges 13 are connected to the pier body template 6 by bolts. There are multiple upper and lower flanges 12, and the supporting steel 15 is connected between the upper and lower flanges 12. The lifting lugs 14 are fixed to the supporting steel 15. The left and right flanges 13 and the upper and lower flanges 12 are jointly arranged on the main frame 11. An adjusting frame 4 is stacked between the upper and lower layers of the positioning frame 1. The adjusting frame 4 includes auxiliary lifting lugs 16, auxiliary left and right flanges 17, auxiliary upper and lower flanges 18, and auxiliary supporting steel 15. 9. The auxiliary left and right flanges 17 are connected to the pier body template 6 by bolts. There are multiple auxiliary upper and lower flanges 18, and the auxiliary support steel 19 is connected between the auxiliary upper and lower flanges 18. The auxiliary lifting lugs 16 are fixed on the auxiliary support steel 19. The auxiliary left and right flanges 17 and the auxiliary upper and lower flanges 18 are connected to each other. The upper and lower flanges 12 are connected to the auxiliary upper and lower flanges 18 of the adjusting frame 4 by bolts. The positioning ear plate 2 is provided with a positioning hook hole. The hook head of the hook bolt 3 matches the positioning hook hole of the positioning ear plate 2. The hook bolt 3 consists of a threaded hook rod with one end bent into a hook shape and a nut. The main frame 11 of the positioning frame 1 is provided with a through hole for the threaded hook rod to pass through. There are multiple through holes.

[0029] The height of the positioning frame 1 is smaller than that of the icebreaker 5 by one adjustment frame height, which facilitates on-site welding of the icebreaker 5. The upper and lower flanges 12 are made of steel plates by CNC cutting according to the shape of the icebreaker, and the upper and lower flanges 12 are fixedly welded with supporting steel 15, which makes the icebreaker 5 more precise in shape. When the icebreaker 5 and the positioning frame 1 are connected by hook bolts 3, the hook bolts 3 can move freely on the main frame 11 of the positioning frame 1. Because the main frame 11 has multiple through holes, the threaded hook rod can pass through the corresponding through hole, which means that the threaded hook rod moves on the main frame 11 in a disguised way, so that the threaded hook rod with hooks contacts the positioning ear plate 2, and the hook head of the threaded hook rod hooks the positioning ear plate 2. The nut is then screwed on the threaded hook rod. In this way, the hook bolt 3 adapts to the error caused by welding of the positioning ear plate 2, making the installation faster during construction.

[0030] When processing the icebreaker 5, the positioning frame 1 is fixed to the flat workbench with bolts. The pre-assembled icebreaker 5 is placed on it. The positioning ear plate 2 is spot welded to the icebreaker 5 according to the design and the corresponding position of the main frame 11 of the positioning frame 1. Then, the positioning ear plate 2 is hooked with the hook bolt 3 to fix the icebreaker 5 and the positioning frame 1 together to form a stable whole. Then, the icebreaker 5 and the internal steel bars are welded to avoid deformation of the icebreaker 5 during welding. The upper and lower pier body templates 6 are composed of several template pieces. Some of them are installed with bolts and left and right flanges 13. The remaining pier body templates 6 need to be connected with screws and threads, which can be seen directly in the figure.

[0031] See Figure 6-7 A welded body connects the icebreakers 5 on the upper and lower positioning frames 1. The welded body includes a lower insertion cylinder 7, a middle insertion cylinder 8, and an upper insertion piece 9. The middle insertion cylinder 8 is inserted into the lower insertion cylinder 7. Both the middle insertion cylinder 8 and the lower insertion cylinder 7 have threaded mounting holes 10. The upper insertion piece 9 is inserted into the middle insertion cylinder 8, and the outer surface of the upper insertion piece 9 has a secondary threaded mounting hole 20 corresponding to the threaded mounting hole 10. A top plate 21 is fixed to the top of both the middle insertion cylinder 8 and the upper insertion piece 9. The size of the top plate 21 is... The lower insertion cylinders 7 are of equal size, and the bottom of the top plate 21 is fixed with a through reinforcing rod 22. The upper through reinforcing rod 22 passes through the top plate 21 of the middle insertion cylinder 8, and the lower through reinforcing rod 22 slides into the lower insertion cylinder 7. The lower insertion cylinder 7, the middle insertion cylinder 8 and the upper insertion part 9 are interlocked to increase the length of the welded body. The auxiliary threaded mounting hole 20 and the threaded mounting hole 10 correspond to each other. After the bolts are inserted, the length of the welded body is adjusted and fixed. The design of the through reinforcing rod 22 enhances the overall strength and ensures that the designed component has strong rigidity.

[0032] In practice, during the segmented construction of the pier column, the positioning frame 1 and the ice-breaking body 5 are fixed together as a stable whole. They are then hoisted to the installation position using the lifting lug 14. The left and right flanges 13 of the positioning frame 1 are connected to the pier body template 6 with bolts. The left and right flanges 13 are actually two flanges located on the left and right sides of the positioning frame 1. Then, the upper and lower segmented ice-breaking bodies 5 are welded together by using the space reserved in the adjustment frame 4 between the upper and lower positioning frames 1. The length of the welded body corresponds to the reserved space in the adjustment frame 4, and the two ends of the welded body correspond to the ice-breaking body 5 and are welded. Then, the adjustment frame 4 is installed and stacked. The adjustment frame 4 is connected to the upper and lower positioning frames 1 and the left and right pier body templates 6 with bolts. Thus, the entire pier body template system forms a whole, ensuring the stability of the template system during the pouring process and eliminating the deformation of the ice-breaking body 5 caused by the impact of concrete pouring or the lateral pressure of concrete. This ensures that the pier column forming effect is consistent with the design requirements.

[0033] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
