Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to a bridge pier column template positioning bracket. Background Art

[0002] The pier is an important load-bearing structure in the bridge construction process, and plays a vital role in the safety and stability of the entire bridge structure. Therefore, it is necessary to strictly control the construction accuracy of the pier to achieve a reasonable force form and ensure the safety of the structure. However, in the actual construction process, it is difficult to accurately control the adjustment of the pier formwork, and it is often the case that the target position cannot be reached after repeated adjustments for a long time. This not only wastes manpower and material resources, but also increases safety risks for construction workers working at heights for a long time, which is prone to safety accidents. If the final template cannot be accurately adjusted to the target position, it will cause deformation and deflection of the pier after forming, affecting the structural appearance and normal force, and creating safety hazards. Therefore, it is necessary to design a device that can accurately position the bridge pier formwork to solve the above problems. Summary of the invention

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0015] This embodiment includes a fixed ring buckle 1, which is like a hoop, with one end of the fixed ring buckle 1 open and the other end closed, and the open end of the fixed ring buckle 1 is fastened together by a fastening screw 2, and the closed end of the fixed ring buckle 1 is integrally connected to a horizontal short connecting rod 3, and the short connecting rod 3 is rotatably connected to a horizontal telescopic cantilever 4, and the telescopic cantilever 4 is a telescopic rod. In this embodiment, the ends of the telescopic cantilever 4 and the short connecting rod 3 are both provided with corresponding circular holes, and the circular hole at the end of the telescopic cantilever 4 is located above the circular hole of the short connecting rod 3, and the bolt 9 vertically passes through the upper and lower circular holes, and the telescopic cantilever 4 can rotate around the bolt 9, and a nut is provided at the lower part of the bolt 9, and the nut is not drawn in the attached figure, and the telescopic cantilever 4 is stopped from rotating by tightening the nut.

[0016] A wire reel 5 is installed at the end of the telescopic boom 4, and the wire reel 5 is rotatable. A suspension wire 6 is wound on the wire reel 5, and a plumb bob 7 is connected to the lower end of the suspension wire 6. The suspension wire 6 is retracted and released by rotating the wire reel 5, thereby adjusting the height of the plumb bob 7. The wire reel 5 used can be a manual rotating reel, that is, a manually rotating wire reel 5, or an electric rotating reel, that is, a wire reel 5 that can be rotated by a motor.

[0017] This embodiment further includes a grid plate 8, which is located below the plumb bob 7. The grid plate 8 used in this embodiment has a side length of 30 cm, and the surface of the grid plate 8 is evenly divided into a number of squares with a side length of 1 cm, and the grid plate 8 is marked with scales.

[0018] When in use, first fix one of the brackets of this embodiment on the four corners of the temporary bracket outside the pier column, embed the fixing ring buckle 1 on the pole, and tighten the fastening screw 2 to ensure the stability of the bracket. Place four square grid plates 8 at the four corners of the pier column, respectively, and place the measuring prism on the grid nodes of the square grid plates 8 at the four corners of the pier column, use the total station to lay out the design coordinates of the four corners of the pier column, and use the scale on the square grid plate 8 to accurately adjust the prism position according to the offset data of the layout result, and then observe, and after reaching the design coordinates, use a marker to mark on the square grid plate 8. Then keep the grid plate 8 in place, rotate the telescopic cantilever 4 to adjust the angle, stretch the telescopic cantilever 4 to adjust the bracket length, adjust the height of the plumb bob 7 through the reel 5, align the plumb bob 7 with the marked point on the grid plate 8, and place the plumb bob 7 directly above the marked point on the grid plate 8. Place a ruler vertically at the marked point on the grid plate 8, and adjust the height of the plumb bob 7 up and down according to the height difference measured by the total station and the ruler scale. After adjustment, the position of the bottom end of the plumb bob 7 is the target position and height of the template. Then adjust the position and height of the template according to the plumb bob 7, so that the four corners of the template are moved to the target positions of the four corners of the template marked by the plumb bob 7 respectively. After the template moves into place, the template is reinforced. In the later stage of the pier column concrete pouring process, the plumb bob 7 can also be used to observe the dynamics of the template in real time. If the concrete pouring causes the template to drift, the template is adjusted in time according to the plumb bob 7 to avoid the problem of secondary offset of the template caused by the concrete pouring.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
