Abstract

The invention provides a compound energy consumption one-way bridge support with a simple construction, convenient machining and stable performance. By using the characteristics of curve and tensile deformation of soft steel curved beams, the support mainly comprises a lower basin (1), an upper basin (2), a spherical cap lining plate (3), a curved beam (4), anchored steel sleeves (9), and anchor bolts (10). The spherical cap lining plate (3) is positioned between the upper basin (2) and the lower basin (1), and is concentrically matched with the upper basin (2). The upper basin (2) and the lower basin (1) are provided with four anchored steel sleeves (9) and the anchor bolts (10) respectively. The curved beam (4) is symmetrically arranged between the upper basin (2) and the lower basin (1), and two ends of the curved beam (4) are hinged with the spherical lining plate (3) and the lower basin (1) respectively. The support allows for the longitudinal bridge deviation between the upper basin and the lower basin, while the transverse bridge deviation is restrained. When the longitudinal bridge deviation between the upper basin and the lower basin occurs, the energy of the system is consumed through the deformation (curve, stretch) of the curved beams to achieve the aim of reducing the vibration; therefore, the conventional support has the function of energy consumption.

Description

technical field [0001] The invention is a composite energy-consuming one-way bridge support device, which is used as a one-way support in bridge engineering, and can play the role of energy dissipation and shock absorption (vibration) on the bridge. Background technique [0002] Energy dissipation shock (vibration) technology is an effective structure control technology, which reduces the response of the structure under dynamic load by installing energy dissipation shock (vibration) devices at appropriate positions in the structure. At present, there are extensive studies on energy-dissipating dampers at home and abroad, but there are few researches and developments on devices that can not only meet the structural functions but also have energy-dissipating characteristics. Research and develop composite energy-consuming devices, and produce damper products with excellent performance, which have important economic and social benefits. The invention proposes a composite energ...
