Embodiment Construction

[0020] Combine below figure 1 and 2 The present invention will be described in detail. Such as figure 1 As shown, the present invention provides a COCS composite bridge deck structure, including an asphalt wear layer 1, a UHPFRC layer 2, a waterproof layer 3, a CLT top plate 4, a corrugated steel plate 5 and a diaphragm 6 arranged in sequence from top to bottom. Layer 1 is laid on the surface of UHPFRC layer 2 , waterproof layer 3 is laid on the surface of CLT roof 4 , and UHPFRC layer 2 and CLT roof 4 are connected by shear connector 9 .

[0021] As mentioned above, COCS is the abbreviation of Corrugated Sheet Steel -Orthotropic CLT - SFRCComposite Bridge Deck System Corrugated Steel Orthotropic Cross-Laminated Timber-Steel Fiber Concrete Composite Bridge Deck System, and UHPFRC is Ultra-High Performance Fiber Reinforced Concrete The abbreviation of reinforced concrete, CLT is the abbreviation of Cross-Laminated Timber. For the convenience of description, the abbreviation ...

Abstract

The invention discloses an A COCS combine bridge deck structure which comprises an asphalt abrasion layer, a UHPFRC layer, a Waterproof layer, CLT top board, a corrugated sheet steel board and a diaphragm board, all of which are orderly arrayed from the top to the bottom. The UHPFRC layer is provided with a ribbed reinforcing steel mesh, the asphalt abrasion layer is laid on the surface of the UHPFRC layer, the waterproof layer is laid on the surface of the CLT top plate, and the UHPFRC layer is connected with the CLT top plate through a shear connector. A CLT top board, the c corrugated sheet steel board and the UHPFRC layer are combined organically, A PZ-type shear connector and a screw connector are used to effectively combine that parts, The advantages of each material are further brought into play to avoid the welding connection of the traditional structure, to overcome the problem of stress concentration at the vulnerable position caused by the number and collection of the structural weld seams, to improve the fatigue resistance of the orthotropic plate, to improve the integrity of the assembled building, to facilitate the manufacture and installation, to be simple in maintenance and to be low in production cost.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a COCS composite bridge deck structure. Background technique [0002] The orthotropic steel bridge deck structure is a combined structural system that bears wheel loads and is composed of a steel deck, transverse and longitudinal stiffeners welded to the deck, and a waterproof layer and a pavement layer on the deck. Because of the remarkable advantages of light weight and high strength, orthotropic steel bridge decks are widely used in the construction of modern long-span steel bridges at home and abroad. However, the fatigue problem caused by complex structure, many weld seams and geometric discontinuities has become a chronic problem hindering the development of orthotropic steel bridge decks. Therefore, in response to the national green building policy, it is an urgent requirement to design a bridge deck that is environmentally friendly, easy to use local materials...
