Background technology
In bridge main beam, boats and ships, at present conventional sheet material is steel plate or traditional sandwich clad steel, this steel plate or traditional sandwich clad steel have the shortcomings such as a large amount of weld seams, inner easy-to-rust, difficulty are safeguarded, rigidity is inadequate, are difficult to adapt to the use under rugged environment and under complicated stressing conditions of bridge, boats and ships.
Utility model content
The purpose of this utility model is the problem existing for prior art, and it is the sandwich that core, steel plate are covering that the employing composite material that a kind of rigidity is large, weld seam is few, intensity is high, be easy to safeguard is provided.
The technical solution adopted in the utility model is: a kind of composite material that adopts is the sandwich that core, steel plate are covering, comprise upper and lower two-layered steel plates covering and middle one deck composite material core, between steel plate covering and composite material core, bond and be bolted by structure glue;
Between multiple described sandwich, be connected by concavo-convex joint, or for increasing bonding strength, connect by two recessed heads, in the middle of two recessed heads, set up a rectangular steel tube, be convenient to welding;
Described composite material core adopts drawing and extruding section bar or sandwich structure, and drawing and extruding section bar is separate type or several monolithic being connected to form.
As preferably, described drawing and extruding section bar comprises I shape, grooved and hollow section.
As preferably, the filler of described sandwich structure comprises wooden or foam.
As preferably, for strengthening its globality, in described sandwich structure, can set up rib.
As preferably, described composite material core is by fiber and resin solidification moulding, fiber comprises carbon fiber, glass fiber, basalt fibre, aramid fiber or hybridization fiber, and resin adopts unsaturated polyester (UP), vinylite, epoxy resin, phenolic resins and all kinds of structure glue.
Beneficial effect: the sandwich that the utility model is combined into by upper and lower two-layered steel plates and middle one deck composite material core, can avoid a large amount of welding job of conventional interlayer steel plate, reduce weld seam; Composite material, as internal material, is protected by steel plate, does not have ultraviolet ageing and fire prevention and poison gas problem, and surface steel sheet is also easy to safeguard; When composite material core adopts hollow section, can also reduce the preserved pipeline of various pipelines.This sandwich can be applied to ship domain, and rigidity is large, intensity is high, abrasion resistance is good, and composite material is as sandwich material, stressed less; Also can be applied in steel case beam and substitute orthotropic plate, rigidity is large, and hogging moment area is few, stressed more reasonable.
