RPC steel joist combined bridge floor and continuous beam bridge

Abstract

The invention provides a RPC steel joist combined bridge floor and a continuous beam bridge. The RPC steel joist combined bridge floor includes a joist-box type beam, the joist-box type beam includesa top plate, a lower wing panel which is arranged at the bottom of the joist-box type beam and two ventral plates, and two sides of the lower portion of the two ventral plates are separately connectedwith RPC stiffening portions in a fixing mode; each of the RPC stiffening portions includes a soffit formwork and a RPC layer, one end of the soffit formwork is fixedly connected below the each of the ventral plates, the other end of the soffit formwork extends outward in the two sides of the joist-box type beam direction, and the RPC layer is filled in a region surrounded by the soffit formwork,the ventral plates and the lower wing panel; and each of the ventral plates is fixedly connected with a small vertical beam, the small vertical beam is fixedly connected with a bridge floor steel bottom plate, and the bridge floor steel bottom plate is poured with a RPC bridge floor. A lower layer bridge floor of the two layer bridge floor is the RPC steel joist combined bridge floor. The bridgefloor of the double layer continuous beam bridge is the RPC steel joist combined double layer bridge floor. The RPC steel joist combined bridge floor and the continuous beam bridge have the advantagesof high strength, light weight, good bearing, fatigue resistance, long service life and so on.

Description

technical field [0001] The invention belongs to the field of bridge structures, in particular to an RPC steel truss composite deck and a continuous girder bridge. Background technique [0002] Most of the existing highways and urban bridges are single-layer plane bridges. Motor vehicles, non-motor vehicles and pedestrians will interfere with each other when passing such bridges, which not only affects the speed of crossing the river, but also makes travel very unsafe, especially with the recent With the rapid development of shared bicycles on the Internet, bicycles have become an indispensable means of transportation for people's daily travel. However, when using bicycles to cross the river, they often face problems such as unsafe bicycle lanes and difficulties in climbing on bridges. Therefore, this This form of bridge does not conform to the development trend of future traffic. In order to solve this problem, the width of the bridge can be increased and two bridges on the...
