Abstract

The utility model belongs to a compound combined material concrete member used for architecture, particularly the buildings used in industrial and civil buildings, railroad and highway bridges, underground railroad projects, dock establishment structures, reservoir dams, water conservancy water-power projects, electric power projects, airfield runways, telecommunication command centers, etc. The utility model thoroughly solves the problems that the reinforcing bar concrete member has large deadweight, high investment, etc., and is corroded and damaged by the chemic raw material such as seawater, steam, water, acid, alkali molecules, etc. Consequently, the compound combined material concrete member not only debases the investment of the buildings, but also greatly enhances the safe use of all kinds of members in the buildings and the capability of resisting the earthquake calamity breakage.

Description

Compound combined material concrete member

The utility model belongs to a kind of " composite combined material concrete component " for building, particularly in can be used for industry and civilian construction, railway and highway bridge, underground railway engineering, terminal facilities structure, reservoir dam and water conservancy and hydropower and power engineering.

In the last hundred years, all be to adopt reinforced concrete member in above-mentioned various engineerings, reinforced concrete member in the Human's production practice, brought into play better action, but also exist the practical problem of five aspects, do not solve so far.

Though first, the reinforcing bar in the reinforced concrete member has high intensity, but decay resistance is poor especially, the area and the city in river, particularly coastal great river, and the building of heavy industry and chemical engineering industry is subjected to the corrosion of the soda acid molecule in seawater, steam, the water, makes the life-span of reinforced concrete member and reliability be subjected to serious threat.In fact there have been many building structure therefore to damage, and can not have used, be forced to remove and rebuild, caused very big loss.

The second, the weight of reinforcing bar in the reinforced concrete member, account for about 1/3 of buildings in general gross weight, account for about 1/2 of highrise building and special use heavy construction thing gross weight.So not only increase the building deadweight greatly and make many engineering design and constructions very difficult, the price of reinforcing bar is more and more higher simultaneously, thereby construction investment is constantly increased.Many enterprise and institution are difficult to bear.Particularly property price soars in recent years, and makes the development of builing industry be subjected to very big impact.What country worked out is to solve the Comfortable Housing Project of house difficulty seldom to realize.

Three, the insulating properties of the reinforcing bar in the reinforced concrete member are very poor, all can produce the interference of very big electromagnetic field to being applied in the buildings such as airport runways and telecommunication command centre, hospital and laboratory, electric substation and modern office equipment computer.

Four, the concrete in the reinforced concrete member in the member use is stressed, can only bear pressure.And crossbeam in the structure and floor, and the fortified defence area that destroys with needs opposing earthquake disaster in the highrise building and the building in city, the multiple bar stress such as curved and tension that is subjected to that produces in the member mainly relies on reinforcing bar to bear, and there are above-mentioned three big problems in reinforcing bar, thereby the reinforcing bar of reinforced concrete member will strengthen conservative design, and the concrete structure sectional area also increases many thereupon.So the deadweight of member increases greatly, and investment also greatly increases.

Five, reinforced concrete member also exists the destruction problem of freezing stress at north cold area, and the method for Xie Jueing is for a long time: the topping of thickening concrete members, or at tens centimeters thick brick wall insulation layers of concrete component outside increase.This method is frozen the stress rupture effect though played to take precautions against, and investment cost increases greatly, because building weight increases greatly, causes bigger difficulty also for design and construction.

" the composite combined material concrete component " that the utility model proposes is the above-mentioned urgency problem to be solved that exists at conventional reinforced concrete member, and the off the beaten track a kind of New Testament part that proposes.And fundamentally solved the big problem of the above-mentioned aspect that the reinforced concrete member exists.Thereby adopt the utility model technology will produce huge economic benefit at each member of from now on building.

Composite combined material in " the composite combined material concrete component " that the utility model proposes is the reinforcing bar that is used for replacing in the reinforced concrete member, and combine closely " composite combined material concrete component " with concrete, its mechanics functional performance is higher than reinforced concrete member, and the corrosive nature of the anti-various chemical raw materials of anticorrosion increases greatly than reinforced concrete member.Resist the also raising greatly of ability that earthquake disaster is destroyed thus.Again because the composite combined material that the present invention proposes has good insulating properties.Therefore, removed reinforced concrete member, to airport runways, dried the scratching of electromagnetic field of laboratory and modern office equipment computer, consequent economic benefit is inestimable.Improved the safety coefficient of taking off and landing greatly.

The composite combined material that the utility model proposes is to be made of following material:

1,65～80% poly-fluorine vinyl chloride, ethene-chlorine fluoride copolymers, ethylene-tetrafluoroethylene copolymer, polyvinylidene fluoride, perfluoro alkoxy, fluorinated ethylene-propylene copolymer, polytetrafluoroethylene (PTFE), 5～10% pottery, 15～25% glass fiber or carbon fiber are composited;

2,35～55% carbon fibers, 45～65% Ceramic Composite forms;

3,40～70% polyvinyl chloride, 4～10% graphite, 10～25% glass fiber or carbon fiber are composited;

4,45～75% polypropylene, 5～15% red soil (or industrial residu), 25～35% carbon fibers or glass fiber are composited;

5,60～80% polystyrene, 3～10% white carbons or French chalk, 20～30% glass fiber or carbon fiber are composited.

6, with thermoplastic and thermosetting plastics, various inorganic filler and organic filler,, be composited by instructions for use with the fibrous matter reinforcing material.

7, with concrete stir even all and improve the concrete in tension stress intensity, and cooperative material has the high fibrous materials of tensile stress intensity such as asbestos long fibre, long glass fiber, synthetic fibers.

8, by 1～7 described material that is composited, replace reinforcing bar being used for concrete component, though various physical performance index has met or exceeded reinforcing bar, hot strength does not satisfy the member instructions for use.Therefore, also need rope or the garden shape wire rod made with asbestos fiber, vinylon fiber, and the wire rod made of the high material of other tensile strengths and above-mentioned composite material are combined into " the composite combined material " of whole use.

The shape facility of " composite combined material " in " the composite combined material concrete component " that the utility model proposes is: garden shape cross section molded about becomes concave-convex and total length prolongation longitudinally, clocklike is twisted into spirality or herringbone.In the middle of the cross section is hole, garden or the hole that is concavo-convex notch.Pass for high wire rods of tensile strength such as vinylon ropes in the hole, two hot weld firmly becomes whole stressed material.Based on the cross section of the composite combined material in the member of compressive strength form around be concavo-convex notch, kernel of section is the solid pore-forming that need not.
