Abstract
The utility model relates to a kind of bar planting stratified fiber reinforced composite beam, this composite material beam by multilayer from nested composite panel forms successively outside to inside composite material beam body, be embedded in composite panel and with the bar planting of beam body axially parallel and form.Compared with prior art, the utility model proposes lamination theory, the inner rigidity of reasonable disposition composite material beam, the foaming FRP material that section bar cortex adopts the larger FRP material of density or do not foam, foams less, have outer hard interior tough, specific strength is high, and the advantage that consumptive material is economized, in conjunction with embedding re-bar technique, implant muscle material in composite inner, efficiently solve the problem that composite material beam rigidity is less, and section bar is for entirely prefabricated, constructs convenient.
Description
Technical field
The utility model belongs to technical field of civil engineering, especially relates to a kind of bar planting stratified fiber reinforced composite beam.
Background technology
In recent years, in building bridge construction, continue concrete structure and steel work, be regarded as the superior function of fiber-reinforced polymer of the third constructional materials gradually by engineering circles is approved, external many engineerings start FRP to be applied in newly-built bridge, or even in Longspan Bridge Local Members.
The application of " foaming " this concept and foamed material has been deep into numerous areas at present, as foamed plastics, foam metal, foam glass, foam concrete etc., even to be called as the National Aquatics Center of " the Water Cube " be also successfully to use bubble theory first in the world and the stadiums that build up in the 2008 Beijing Olympic Games, its steel superstructure adopts the polyhedron space steel frame form of structure based on bubble theory, and appearance appears in public with the image that is full of bubble.
Utility model content
The purpose of this utility model is exactly the bar planting stratified fiber reinforced composite beam that provides in order to overcome the defect that above-mentioned prior art exists that a kind of intensity is high, consumptive material is economized, efficiently solves the problem that composite material beam rigidity is less.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of bar planting stratified fiber reinforced composite beam, by multilayer from nested composite panel forms successively outside to inside composite material beam body, be embedded in composite panel and with the bar planting of beam body axially parallel and form.
Multilayer successively nested composite panel is successively decreased successively from rigidity outside to inside, forms outer toughly in hard, reaches the object of saving material.
Described composite panel is fiber-reinforced composite material board, realizes rigidity and reduces successively by controlling the density of every layer of composite panel.In described fiber-reinforced composite material board, fortifying fibre used is glass fiber, carbon fiber, basalt fibre, aramid fiber or boron fibre, and matrix used is vinyl, epoxy resin, polyurethane or phenolic resins.
Described composite panel is foamed fibre reinforced composite plate, realizes rigidity reduce successively by the content of control blowing agent.In described foamed fibre reinforced composite plate, foamed fibre used is glass fiber, carbon fiber, basalt fibre, aramid fiber or boron fibre, and matrix used is phenolic resins.
Described bar planting is reinforcing bar, fiber-reinforced composite material rib material or bamboo.
In described fiber-reinforced composite material rib material, fortifying fibre used is glass fiber, carbon fiber, basalt fibre, aramid fiber or boron fibre, and matrix used is vinyl, epoxy resin, polyurethane or phenolic resins.
The shape of bar planting stratified fiber reinforced composite beam is determined according to engineering is actual, is rectangle, circle or oval.
The shape of described bar planting is determined according to engineering is actual, is circle, rectangle or ellipse.
Compared with prior art, the utlity model has following advantage:
(1) lamination theory has been proposed, the inner rigidity of reasonable disposition composite material beam, the foaming FRP material that section bar cortex adopts the larger FRP material of density or do not foam, foams less, has outer toughly in hard, and specific strength is high, the advantage that consumptive material is economized.
(2) in conjunction with embedding re-bar technique, implant muscle material in composite inner, efficiently solve the problem that composite material beam rigidity is less.
(3) section bar, for entirely prefabricated, is constructed convenient.
