Description

Technical Field

[0001] The invention belongs to the technical field of bridge construction, relates to bridge piers, and in particular to a bracket positioning platform and a positioning method for rectangular piers. Background Art

[0002] In bridge construction, the cap beam support meets the construction load of the cap beam by means of climbing cones and corbels attached to the piers. In this support system, the height of the corbel determines the height of the cap beam formwork support, and the installation accuracy of the climbing cone affects the installation quality of the corbel. Therefore, the installation and positioning accuracy of the corbel is particularly important, which will affect the reliability and safety of the overall support.

[0003] The traditional installation method is to fix multiple corbels on the pier, and each corbel is provided with multiple climbing cone points. If a single climbing cone is pre-buried separately, the climbing cone may be misaligned or deformed during the pouring of pier concrete, which directly affects the installation quality and stress of the corbel. In severe cases, the corbel cannot be installed, thereby reducing the overall reliability and safety of the bracket, and even causing the bracket to collapse.

[0004] Therefore, we propose a corbel positioning platform and positioning method for rectangular pier columns to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a corbel positioning platform and a positioning method for a rectangular pier column which are accurate in positioning and easy to install.

[0006] To solve the above problems, the technical solution of the present invention is:

[0007] A bracket positioning platform for a rectangular pier column, comprising:

[0008] The positioning platform is fixedly installed on the template of the pier column to form a closed loop structure around the pier column;

[0009] The corbel is arranged on the positioning platform and is fixed on the pier column through a climbing cone;

[0010] The positioning platform comprises a plurality of platform bodies and a leveling unit. The leveling units are fixedly installed on the plurality of platform bodies and are suitable for adjusting the installation level of the platform bodies.

[0011] In a further embodiment, the leveling unit includes a plurality of azimuth bubble gauges and a plurality of horizontal bubble gauges, the azimuth bubble gauges are commonly installed at the ends of adjacent platform bodies, and the horizontal bubble gauges are fixedly installed in the middle of the platform body.

[0012] In a further embodiment, a plurality of platform bodies form a rectangular structure around the pier, and a plurality of azimuth bubble meters are respectively located at the four corners of the rectangular structure.

[0013] In a further embodiment, bolt holes are formed on the platform body to facilitate installation on the template of the pier.

[0014] In a further embodiment, the climbing cone is fixedly mounted on the main reinforcement of the pier column through a plurality of positioning reinforcements.

[0015] In a further embodiment, the main reinforcement is arranged vertically and the positioning reinforcement is arranged horizontally.

[0016] In a further embodiment, an anchor plate is sandwiched between the corbel and the outer surface of the pier.

[0017] A method for positioning a bracket for a rectangular pier column, wherein a positioning platform is fixedly installed on the pier column, and comprises the following steps:

[0018] Step S101: Assembling the positioning platform

[0019] Connecting a plurality of platform bodies, a plurality of azimuth bubble meters and a plurality of level bubble meters to form a positioning platform;

[0020] Adjust the levelness of the positioning platform through the azimuth bubble meter and the level bubble meter;

[0021] The positioning platform is fixedly installed on the formwork of the pier column;

[0022] Step S103: Install the corbel

[0023] Fix the anchor plate and climbing cone on the side of the corbel in sequence; place the corbel on the positioning platform;

[0024] Step S105: Install climbing cone

[0025] The climbing cone is fixed on the main reinforcement of the pier column through positioning reinforcement.

[0026] In a further embodiment, after the climbing cone and the corbel are connected in step S103, the horizontality of the positioning platform is adjusted again by using the azimuth bubble meter and the level bubble meter.

[0027] In a further embodiment, after the climbing cone is installed in step S105 and the concrete pouring of the pier is completed, the positioning platform is disassembled and is suitable for recycling.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The platform body of this positioning platform forms a closed structure around the pier column. Several azimuth bubble gauges are fixedly installed at the four corners of the platform body, and a horizontal bubble gauge is fixedly installed in the middle of the platform body. The azimuth bubble gauge and the horizontal bubble gauge cooperate with each other to ensure the installation level of the positioning platform, and then locate the installation position of the corbel to ensure that the corbel is installed firmly and accurately. After the construction is completed, the positioning platform can be disassembled and assembled again when used next time. It is convenient and quick, can be reused, and reduces construction costs.
