Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] refer to figure 1 and image 3 , the present invention is suitable for a self-balancing cable anchoring structure in bridge piers and bridge towers, including columns 10 of bridge piers and bridge towers, and left and right cables 11a and 11b anchored on the columns 10 . The cylinder 10 is a hollow structure with any cross-sectional shape, and a solid section 13 is arranged in the cylinder 10 at the anchoring positions of the left cable 11a and the right cable 11b, and a trapezoidal anchoring tooth block structure 12 is arranged on the top of the solid section 13 . The trapezoidal anchoring tooth block structure 12 and the solid section 13 adopt a reinforced concrete structure, and the slope of the two sides of the trapezoidal anchoring tooth block structure 12 ensures that the left cable 11a and the right cable 11b can be vertically anchored ...

Abstract

The invention discloses a self-balancing type stay-rope anchoring structure applicable to inner parts of bridge piers and bridge towers. The self-balancing type stay-rope anchoring structure has the advantages that the stay-rope anchoring structure is effectively simplified, the problems of difficulty in operation and the like caused by narrow construction space in the bridge towers (bridge piers) are avoided, the design and construction difficulties are reduced and the cost of bridge engineering is greatly reduced. The self-balancing type stay-rope anchoring structure comprises a column body of the bridge pier or the bridge tower, a left-side stay rope and a right-side stay rope, wherein the left-side stay rope and the right-side stay rope are anchored on the column body; the column body is of a hollow structure with any section shape; and solid sections are arranged in the column body and at the anchoring positions of the left-side stay rope and the right-side stay rope, and trapezoidal anchoring teeth block structures are arranged at the upper parts of the solid sections. The trapezoidal anchoring teeth block structures and the solid sections adopt reinforced concrete structures, the inclination of the two side edges of the trapezoidal anchoring teeth block structures guarantees that the left-side stay rope and the right-side stay rope can be vertically anchored to the trapezoidal anchoring teeth block structures along the axis, the generated horizontal component forces are counteracted mutually, and the vertical component forces are transferred to the column body from the solid sections.

Description

technical field [0001] The invention relates to bridge engineering, in particular to a self-balancing cable anchorage structure system suitable for bridge piers and bridge towers, which can be used for anchorage of buckles, back cables and stay cables in bridge piers or bridge towers during bridge cantilever construction. Background technique [0002] In recent years, the construction of long-span bridges in my country has achieved rapid development, and a large number of long-span complex bridges with novel structures, complex technologies and difficult construction have been built. Among them, the most representative ones should belong to arch bridge and cable-stayed bridge. Arch bridges and cable-stayed bridges have gradually become the two preferred bridge types for crossing canyon terrain and water systems due to their advantages such as high structural rigidity, strong spanning ability, and easy adaptability to the environment. However, whether it is an arch bridge or...
