At the same time, bridge construction has also promoted the research and development and application of new technologies, new materials and new processes, and promoted the scientific and technological progress and industrial upgrading of the entire society.

[0003] The tied arch bridge, also known as the thrust-free arch-type combined system bridge, is a member of the arch bridge family and has the advantages of both arch and beam. It combines the two basic structural forms of arch and beam to bear the load together, giving full play to the structural performance and combined effect of the beam being bent and the arch being compressed. The tied arch bridge transmits the horizontal thrust of the arch to the piers through the tie rods, thereby reducing the size and number of the piers, making the bridge lighter and more beautiful. In addition, the tied arch bridge is an over-static system inside and statically determinate outside, which has no effect on the uneven settlement of the piers. As a bridge structure that combines the advantages of arch and beam, the tied arch bridge has the advantages of high structural rigidity, strong bending resistance, and high bearing capacity. Its unique structural characteristics and wide application fields make the tied arch bridge play an important role in bridge construction and other construction fields.

[0004] The main longitudinal force system of the tied arch bridge is composed of arch ribs, tie rods and hangers. During the construction process, it is necessary to strictly control the construction accuracy and construction technology, especially the construction of hangers. Before the construction of hangers, the position of the anchor ear plates at the beam ends and arch ends should be checked to ensure the accurate installation of hangers. Therefore, it is of great significance to design a device for accurate calibration and measurement of anchor ear plates. Summary of the invention

[0007] Furthermore, the anchor head main plate comprises a top plate, a bottom plate and a web plate, and the top plate and the bottom plate are connected together through the web plate.

[0008] Furthermore, the top plate and the bottom plate are provided with pin holes, the outer side of the web plate is provided with an annular mortise, and the inner side is provided with a rounded corner at the connection with the top plate and the bottom plate.

[0009] Furthermore, the latch includes a shaft nut and a shaft column, and the diameter of the shaft nut is larger than that of the shaft column.

[0010] Furthermore, a tenon is provided at the lower end of the adjusting sleeve, and is connected to the annular mortise on the outer side of the web of the anchor head main board through the tenon.

[0011] Furthermore, a central small hole is left in the center. Two layers of limit plates are arranged inside the adjusting sleeve, and small holes are arranged in the center of the limit plates and the top plate, and the diameter of the top surface small hole is smaller than the small hole of the limit plate.

[0012] Furthermore, the target ring scale is calibrated to millimeter level.

[0013] Furthermore, when in use, the ear plate calibration and measuring devices of the two sets of double-fork ear hangers are respectively fixed on the hanger ear plates of the beam section and the arch end. When the laser pen in the ear plate calibration and measuring device at the beam end points to the center of the calibration target ring at the arch end, and at the same time, the laser pen in the ear plate calibration and measuring device at the arch end points to the center of the calibration target ring at the beam end, it indicates that the position of this group of ear plates is accurate; if one of the laser pens points to other positions of the calibration target ring, the ear plate can be adjusted accordingly according to the number of calibration target rings until the laser pen points to the center of the calibration target ring of the ear plate calibration and measuring device of the double-fork ear hanger.
