[0002] Bridge pier formwork is a mold structure used to cast concrete for bridge piers and shape them. It is usually made of steel, wood or composite materials. Designed according to the shape and size of the pier, the formwork must have sufficient strength, rigidity and stability to withstand the pressure and lateral pressure during concrete pouring, and ensure the pier's dimensions are accurate and the surface is flat.

[0003] In the construction of highway bridge piers, steel formwork is usually designed and manufactured for piers of a specific diameter. Once piers of different diameters need to be built, new formwork needs to be customized. This is not only time-consuming and labor-intensive, but also greatly increases construction costs. In addition, steel formwork lacks flexibility and is difficult to adapt to different shapes and sizes, which limits its application in various highway bridge projects. Therefore, it is necessary to provide steel formwork for bridge piers that can flexibly adjust the diameter of the formwork by increasing or decreasing the number of rectangular steel molds according to actual needs, so as to meet the construction requirements of piers of different diameters, greatly improve the versatility of the formwork, and reduce the cost of custom formwork.

[0013] In the following description, embodiments of the steel formwork for bridge piers of this utility model will be described with reference to the accompanying drawings.

[0014] Figure 1-4 This invention illustrates a steel formwork for bridge piers according to an embodiment of the present invention, comprising a first arc-shaped steel mold 1; a second arc-shaped steel mold 2 is disposed on the right side of the first arc-shaped steel mold 1; a plurality of rectangular steel molds 3 are disposed between the first arc-shaped steel mold 1 and the second arc-shaped steel mold 2; three connecting plates 4 are welded to the left side of the rectangular steel molds 3; three connecting slots 5 adapted to the connecting plates 4 are provided on the right side of the rectangular steel molds 3; assembly slots 6 are provided at the front and rear ends of the first arc-shaped steel mold 1 near the second arc-shaped steel mold 2; and the front end of the second arc-shaped steel mold 2 near the first arc-shaped steel mold 1... Multiple assembly plates 7, compatible with the assembly slots 6, are welded to both the front and rear ends. Tensioning components 8 are provided on both the front and rear sides between the first arc-shaped steel mold 1 and the second arc-shaped steel mold 2. Each tensioning component 8 includes a rotating frame 81, with threaded pull rods 82 extending through both sides of the rotating frame 81. Hexagonal threaded sleeves 85 are welded to both sides of the rotating frame 81, and the threaded pull rods 82 are threaded into the inner cavity of the hexagonal threaded sleeves 85. Two rotating seats 83 are rotatably connected to the front and rear sides of both the first arc-shaped steel mold 1 and the second arc-shaped steel mold 2. An extrusion plate 12 is welded to one side of each rotating seat 83. The side of the pressure plate 12 away from the rotating seat 83 is tightly fitted to the surface of the rectangular steel mold 3. The rotating seat 83 has a hanging hole 84 on its surface, and the threaded pull rod 82 is fastened into the inner cavity of the hanging hole 84. Through the tensioning assembly 8, the rotating frame 81 and the threaded pull rod 82 work together to pull the rotating seat 83. Simultaneously, the working relationship between the rotating seat 83 and the hanging hole 84 allows the first arc-shaped steel mold 1 and the second arc-shaped steel mold 2 to be pulled and tightened, thereby improving the stability between the first arc-shaped steel mold 1, the second arc-shaped steel mold 2, and the rectangular steel mold 3. Furthermore, it can be tightened and fixed according to different diameters. Multiple bolts 9 are welded to the top of the first arc-shaped steel mold 1, the second arc-shaped steel mold 2, and the rectangular steel mold 3. Connection holes 10 are opened at the bottom of the first arc-shaped steel mold 1, the second arc-shaped steel mold 2, and the rectangular steel mold 3. The bolts 9 are inserted into the inner cavity of the connection holes 10. The surface of the bolts 9 is threaded with nuts 11. Through the cooperation of the bolts 9, the connection holes 10, and the nuts 11, the vertically distributed first arc-shaped steel mold 1, second arc-shaped steel mold 2, and rectangular steel mold 3 are connected and fixed, thereby enhancing the stability of the formed mold.

[0015] Working Principle: When using this invention, the user takes an appropriate number of rectangular steel molds 3 and moves them to the right side of the first arc-shaped steel mold 1, so that the connecting plate 4 engages with the inner cavity of the assembly slot 6, connecting the first arc-shaped steel mold 1 and the rectangular steel mold 3. Simultaneously, the second rectangular steel mold 3 is moved to the right side of the first rectangular steel mold 3, so that the connecting plate 4 engages with the inner cavity of the connecting slot 5. Finally, the second arc-shaped steel mold 2 is moved to the right side of the second rectangular steel mold 3, so that the assembly plate 7 engages with the inner cavity of the connecting slot 5, thus forming an integral mold from the first arc-shaped steel mold 1, the second arc-shaped steel mold 2, and the rectangular steel mold 3. The user then places the threaded pull rod 82 into the inner cavity of the hanging hole 84 and uses a pry bar... Insert the rotating frame 81 into the inner cavity and rotate the rotating frame 81. During the rotation, the rotating frame 81 drives the hexagonal threaded sleeve 85 to rotate. With the cooperation of the inner wall thread of the hexagonal threaded sleeve 85 and the surface thread of the threaded pull rod 82, the rotating seat 83 can be pulled. Continue to rotate the rotating frame 81 until the extrusion plate 12 is pressed against the surface of the rectangular steel mold 3 and the rotating frame 81 can no longer rotate. At this time, the first arc-shaped steel mold 1, the second arc-shaped steel mold 2 and the rectangular steel mold 3 are installed stably. Then, the user performs vertical assembly according to the above assembly method. During assembly, simply put the connecting hole 10 on the surface of the bolt 9 and rotate the nut 11 thread to the surface of the bolt 9 to lock it.

[0016] In summary, the steel formwork for the bridge piers, through the combined use of the first arc-shaped steel mold 1, the second arc-shaped steel mold 2, and the rectangular steel mold 3, forms the pier support formwork. Simultaneously, by increasing or decreasing the number of rectangular steel molds 3, the diameter formed by the first arc-shaped steel mold 1, the second arc-shaped steel mold 2, and the rectangular steel mold 3 can be adjusted. Furthermore, the combined use of the tensioning assembly 8, bolts 9, and connecting holes 10 allows for the assembly and fixation of the first arc-shaped steel mold 1, the second arc-shaped steel mold 2, and the rectangular steel mold 3, thus achieving the goal of easy diameter adjustment and stable and reliable installation.
