Embodiment 1

[0026] Such as figure 1 Shown is a schematic diagram of the durability improvement structure of the steel-concrete composite bridge of the present invention, including steel 1 , reinforced concrete 2 , steel needle 3 , waterproof brick 4 , rubber 5 and mortar 6 .

[0027] Reinforced concrete 2 is poured on the bottom of the outer surface of steel 1, and a plurality of steel needles 3 are set at the position where steel 1 and reinforced concrete 2 are connected. The specific number of steel needles 3 is not limited, and can be selected according to construction requirements and conditions.

[0028] In a preferred manner, the steel needles 3 are divided into two groups, and the two groups of steel needles 3 are arranged at an angle of 30 degrees to each other, and are respectively welded to the outer surface of the steel material 1 .

[0029] In another preferred manner, the steel needles 3 are divided into two groups, and the two groups of steel needles 3 are arranged at an ang...

Abstract

The invention discloses a steel-concrete-composite-bridge durability improving construction and a construction method. The steel-concrete-composite-bridge durability improving construction comprises steel and reinforced concrete fixedly connected with the steel; a plurality of steel needles are arranged at the position, connected with the reinforced concrete, on the steel and used for increasing the contact area of the steel and the reinforced concrete. By means of the steel-concrete-composite-bridge durability improving construction and the construction method, generation of a crack of the contact face of a steel-concrete composite structure can be reduced, and meanwhile it is prevented that rainwater enters the crack of the contact face; a certain quantity of the steel needles are welded on the steel for being capable of increasing the contact area of the steel and the reinforced concrete, and the possibility of crack developing is reduced; a slope of 5% is set on the upper surface of the reinforced concrete, and rainwater can conveniently and rapidly flows down from the surface of the reinforced concrete; rubber has the certain elasticity, the rubber, the steel and a waterproof face brick can be firmly bonded, and therefore it can be guaranteed that a gap does not exist between the waterproof face brick and the steel when the crank exists between the reinforced concrete and the steel.

Description

technical field [0001] The invention relates to a waterproof structure, in particular to a durability improvement structure and a construction method of a steel-concrete composite bridge. Background technique [0002] The steel-concrete composite structure is a structure in which steel components and reinforced concrete components are combined to form a whole and work together, and has some characteristics of steel structures and reinforced concrete structures. It can be used for floor beams, trusses, slabs and columns in multi-storey and high-rise buildings, roof panels, beams and trusses in roof structures, columns and working platform beams, slabs and bridges in factory buildings, and also used in factory buildings in China In recent years, the crane girder has been widely used in corrugated steel web bridges and cable-stayed bridges. There are four types of steel and concrete composite structures: composite beams, composite slabs, composite trusses, and composite column...
