Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] Such as Figure 1-5 Shown: a composite orthogonal grid structure sandwich bridge deck with reinforcements, including a composite material orthogonal grid structure core layer 1, a composite material panel 2 with a thickness of 10 mm and a composite material reinforcement system 3;
[0018] The composite orthogonal grid structure core layer 1 is arranged between the upper and lower composite material panels 2 and connected by structural glue. The composite material orthogonal grid structure core layer 1 is composed of mutually perpendicular vertical ribs 4 Constituted with a 10mm thick transverse rib 5;
[0019] In order to strengthen the connection between the longitudinal and horizontal ribs so that they can be co-ordinated, a composite material reinforcement system 3 can be arranged at the intersection node of the composite material o...

The invention discloses a sandwich bridge deck with reinforcing components and in a composite material orthogonal grid structure. The sandwich bridge deck comprises a composite material orthogonal grid structure core layer, composite material panels, and composite material reinforcing component systems, wherein the composite material orthogonal grid structure core layer is arranged between the upper composite material panel and the lower composite material panel and connected with the panels through structural adhesive, the composite material orthogonal grid structure core layer comprises longitudinal ribbed plates and transverse ribbed plates which are vertical in a corresponding manner, the composite material reinforcing component systems are arranged at cross nodes of the composite material orthogonal grid structure core layer, the composite material reinforcing component systems and the composite material orthogonal grid structure core layer are connected through the structural adhesive and shearing bolts, each composite material reinforcing component system comprises four reinforcing components, and each reinforcing component comprises two vertical side plates, an upper plate and a lower plate. The bridge deck disclosed by the invention has the obvious characteristics of light weight, high strength, high rigidness, stripping resistance, dampness resistance, corrosion resistance, simplicity, convenience and rapidness for splicing and construction, and the like, and is suitable for various bridge deck projects.
Description
technical field [0001] The invention relates to the technical field of bridge deck structures, in particular to a composite bridge deck structure that can be used as a sandwich bridge deck in bridge structures, specifically a lightweight, high-strength, corrosion-resistant factory prefabricated bridge deck structure with reinforcements Composite Orthogonal Grid Structure Sandwich Bridge Deck. Background technique [0002] Due to the intrusion of moisture into the core layer of traditional composite sandwich panels, the core layer will easily corrode over time and weaken its bearing capacity, causing safety hazards. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, and provide a kind of anti-corrosion, waterproof, anti-cracking, good interlayer bonding performance and flexible processing technology, which is a factory-fabricated composite material orthogonal grid structure sandwich bridge with reinfor...
