A solid web type rigid suspender and its installation method

Abstract

The invention discloses a solid web type rigid suspender and an installation method of the solid web type rigid suspender. The member comprises a panel, the panel is in a solid structure, the edge of the side surface of the panel is removed along the length direction to form a chamfer, a wing plate is arranged on each of the opposite two sides of at least one end part of the panel, the two wing plates are both vertical to the width direction of the panel, the wing plates at the upper end parts of the panel are used for connecting an arched beam, the lower part of the panel is used for connecting a bridge floor, the method comprises the steps of connecting the two wing plates and the panel to form an integrity, then fixing the two wing plates with the arched beam and the bridge floor sequentially. By using the member, the aerodynamic configuration of the panel is effectively improved, the wind-induced vibration is reduced, the vortex-induced resonance is inhibited, the wind load resistance of the panel is improved, the torsional amplitude of the end part of the suspender is reduced, the fracture of the end part is avoided, and the safety is improved; adopting the method is favorable for controlling the perpendicularity of the panel, the installation height is conveniently adjusted, the connection is more stable, and the method is convenient in construction.

Description

technical field [0001] The invention relates to the field of building engineering construction, in particular to a solid web type rigid suspender and an installation method. Background technique [0002] Arch bridges are widely used because of their beautiful shape, economy and practicality, and large spanning capacity. In the middle and lower-through arch bridges, rigid suspenders and flexible suspenders are two commonly used structural forms of suspenders. As the main bearing of this type of bridge As a force component, the suspender is used to connect the arch beam and the bridge deck system, transfer the load of the bridge deck system in the bridge span to the arch beam, and then transfer the load to the abutment through the arch beam, so the safety of the suspender is directly It affects the safety, durability and normal use of the arch bridge structure, but the arch bridge has the basic characteristics of large span and low stiffness, and is sensitive to wind load. The...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies such as the poor wind resistance of the existing rigid suspenders, which are greatly affected by wind-induced vibrations, and the ends are prone to generate large torques, resulting in damage to the rigid suspenders, and provide a solid web type rigid suspender And the installation method, effectively improve the aerodynamic shape of the rigid boom, improve the wind pressure resistance of the rigid boom, effectively reduce the torque on its end, and prolong the service life
