O-shaped steel bar connecting structure

Abstract

The invention relates to an O-shaped steel bar connecting structure. The O-shaped steel bar connecting structure comprises two rows of U-shaped steel bars arranged on different concrete components. The two rows of the U-shaped steel bars are oppositely overlapped and crossed to form the O-shaped steel bar structure which is internally provided with a plurality of supporting cushion steel bars and forms anchorage-type connecting through pressure-bearing concrete pouring. According to the O-shaped steel bar connecting structure, a traditional mode and a force-transferring mechanism of steel bar connecting are changed, the width of a wet joint formed by connecting is greatly reduced to be less than half of the width of a non-welding wet joint of a traditional steel bar, steel bar connecting and component jointing are simplified, material using is reduced, engineering cost is reduced, the workload is greatly reduced, construction site quick connecting of factory precast concrete components is achieved, and development of a bridge girder industrial construction technology is promoted.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to an O-shaped steel bar connection structure. Background technique [0002] At present, adopting a structural point of view and an industrialized model to implement the construction of less soil, no soil, high efficiency, and low-cost projects at the level of scale and serialization is becoming the development direction of my country's green road construction. Among them, the complete set of technology for small and medium-sized structures is a key part of the implementation of green road construction and road industrialization. After years of exploration, although this technology has been greatly developed and the demonstration effect is good, there are still many shortcomings: such as insufficient large-scale construction, absence of key structures, lagging control structures, and lack of theoretical breakthroughs. [0003] The wet joint reinforcement conne...

After years of exploration, although this technology has been greatly developed and the demonstration effect is good, there are still many shortcomings: such as insufficient large-scale construction, absence of key structures, lagging control structure and lack of theoretical breakthroughs

[0003] The wet joint reinforcement connection between precast concrete components has always been a difficult problem in domestic design and construction: when the steel bars are lapped and welded according to the specifications, the wet joints are too wide and the workload is too large. If other connection methods are used, the connection The effect cannot be guaranteed
