Embodiment Construction

[0028] The following descriptions are only preferred embodiments of the present invention, and do not limit the scope of the present invention.

[0029] Example: as attached figure 1 , 2 , 3 and attached Figure 4 As shown, a stiffened longitudinal girder structure to enhance the robustness of the suspension bridge system of a mid-through arch bridge includes a large pipe unit 1 and a small pipe unit 2 that are nested in each other, and are respectively arranged on the large pipe unit 1 and the small pipe. Two anchoring steel plate units 3 on the outer end of the unit 2 and used to connect the beam 11.

[0030] In this embodiment, suspenders 13 are installed at both ends of the beams 11 according to the prior art to support the bridge deck 12, and the stiffened longitudinal beam structures are arranged between two beams 11 for Ensure that the entire suspension bridge system has greater robustness, and has the advantages of high rigidity and high stability.

Abstract

The invention belongs to the technical field of bridge engineering, and particularly relates to a stiffening longitudinal beam structure for enhancing the robustness of a half-through arch bridge suspension bridge system and a construction method thereof. The large pipe unit and the small pipe unit are connected in a sleeved mode, the supporting pipe unit is inserted, and the anchoring steel plate unit is installed, so that the effect of installing the stiffening longitudinal beam structure between the two cross beams is achieved. The stiffening longitudinal beam structure has the advantages that the steel structure stiffening longitudinal beam is light in weight, large in rigidity and easy to connect, the overall rigidity and stability of a suspension bridge road system are greatly improved, inconsistent deformation, caused by temperature changes, of a bridge floor and the stiffening longitudinal beam can be fully released, impact force generated by suspender breakage can be borne on a certain length, and the robustness of the suspension bridge road system is enhanced; major accidents can be effectively avoided, and good economic value and social effect are achieved.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a stiffened longitudinal beam structure and a construction method for enhancing the robustness of a suspension bridge system of a mid-supporting arch bridge. Background technique [0002] At present, the design of the suspension bridge system of the mid-supporting arch bridge in my country is not based on the stress of the stiffened longitudinal beam, but on the beam. The suspenders are also anchored at both ends of the beam, and then the bridge deck is laid on the beam. Most There is no stiffening stringer between beams. After several years of operation and use of the built half-supported arch bridge, there are many diseases in the suspension bridge system, such as excessive vibration of the bridge deck, serious damage of the bridge deck, and falling off of the support, etc., and have occurred one after another in recent years. There have been many serious...
