Guardrail roadbed combined structure for bridge

Abstract

The invention discloses a guardrail and roadbed combined structure for a bridge, which comprises a guardrail and a roadbed, the guardrail comprises a guardrail body and a plurality of fixing pieces arranged on the guardrail body, all the fixing pieces are sequentially arranged along the length direction of the guardrail body, the roadbed comprises roadbed surface transverse bars and roadbed surface longitudinal bars which are in cross connection. The roadbed surface transverse bars are connected with the fixing pieces, and a plurality of roadbed surface transverse bars and roadbed surface longitudinal bars are arranged. According to the guardrail and roadbed combined structure for the bridge, traditional stress rib and through rib operation is reduced, procedures are effectively saved in actual construction, the construction cost is reduced, meanwhile, an overall bridge deck structure formed by the guardrail and the roadbed surface achieves integrated pouring of the guardrail and the roadbed, binding force of concrete, rib plates and a reinforcing mesh is facilitated, and the stability and shock resistance of the bridge pavement structure are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, in particular, the invention relates to a combination structure of guardrail roadbed for bridges. Background technique [0002] With the rapid development of economy, my country's bridge engineering construction has made rapid progress. At present, in the construction of bridge structures, due to the different construction conditions and construction environments on site, there are various types of bridge structures. Generally, bridge construction follows two parts: pier structure construction and bearing structure construction. Among them, for the bearing part of the bridge, with the development of modern assembly processing and engineering technology, the main structure of super-large bridges is usually constructed in the form of prefabricated assembly structure. For some small and medium-sized bridges, due to the infrastructure environment and engineering requirements, the traditi...

Problems solved by technology

Although this method can be made in the factory to reduce the traffic under the bridge during the construction period, the prefabricated installation in the factory requires welding between the chords and webs, etc. In fact, a large number of welding processes are added before on-site pouring. For the traditional steel mesh Structurally, this method is too costly
