Abstract
本实用新型公开了一种具有强度高、延性好、握裹力强、耐腐蚀的复合筋材。该复合筋材包括：筋材，在筋材的外部覆盖有纤维树脂复合层。本实用新型的筋材被包裹于纤维树脂复合材层，这样就结合了纤维树脂复合材层的高强度、耐腐蚀性和钢材的延性好的优点，同时纤维树脂复合层外表面上进行纤维缠绕、勒痕或喷砂时，复合筋材的外表壁粗糙，握裹力强，易于和其他物体如混凝土等粘结，因而本实用新型的握裹力也较好。钢筋为变形钢筋，表面有肋，而钢丝直径小，侧面的比表面积大，因此均能与纤维树脂复合层粘合牢靠，整体强度也更佳。
The utility model discloses a composite tendon material with high strength, good ductility, strong gripping force and corrosion resistance. The composite reinforcement includes: a reinforcement, and the outside of the reinforcement is covered with a fiber resin composite layer. The ribs of the utility model are wrapped in the fiber resin composite layer, which combines the advantages of high strength, corrosion resistance and steel ductility of the fiber resin composite layer, and at the same time, fiber winding is performed on the outer surface of the fiber resin composite layer , Stretching marks or sandblasting, the outer wall of the composite reinforcement is rough, the gripping force is strong, and it is easy to bond with other objects such as concrete, so the utility model has better gripping force. The steel bar is a deformed steel bar with ribs on the surface, and the diameter of the steel wire is small, and the specific surface area of the side is large, so it can be firmly bonded to the fiber resin composite layer, and the overall strength is also better.
Description
Technical field
The utility model relates to a kind of compound muscle material.
Background technology
In the reinforced concrete structure of building construction, bridge, water conservancy project, owing to steel easily get rusty under the environment that the aerobic G﹠W divides, thereby cause many structures to be corroded in the long-time back of coming into operation, supporting capacity and durability performance are degenerated.Even concrete protective is arranged, owing to unavoidably have many microcracks in the concrete, concrete cracking place reinforcing bar still corrodes because of lacking protection, and the structural element crackle is constantly expanded, corrosion is constantly deepened, and final component damage causes the generation of accident; And for built structures, reinforcement and strengthening is cumbersome, and cost is bigger.At present, a kind of anti-corrosion measure of employing is to adopt epoxy coating, and epoxy coating is that rebar surface is made one deck epoxy resin thin film topping, and it has the good advantage of chemical stability.Yet because coating bullet mould is little, intensity is low, and bond stress is poor.And it is impaired to be prone to coating in lifting, processing, carrying, colligation and concreting process, and therefore actual antiseptic effect descends to some extent.
FRP is a kind of high performance fibrous composite, corrosion resistance and good, intensity height.The application of FRP in building construction, structure, road, bridge, ground, hydraulic engineering has wide space.But if as main force structure material, its application is but because of the characteristics of non-plastic are subjected to certain restriction, and independent applying FRP bears pulling force in the member, has the risk that FRP ruptures suddenly, member destroys suddenly.
Summary of the invention
The utility model provides a kind of and has had the intensity height, ductility is good, bond stress is strong, corrosion resistant compound muscle material.
The utility model solves technical problem by the following technical programs;
A kind of compound muscle material comprises: the muscle material is coated with the fibre resin composite bed in the outside of muscle material.
Compared with prior art, the utlity model has following advantage;
1. muscle material of the present utility model is wrapped in the fibre resin composite bed, so just combine the good advantage of ductility of high strength, corrosion resistance and the steel of fibre resin composite bed, carry out on the fibre resin composite bed external surface simultaneously fiber twine, when reining in trace or sandblast, the appearance wall of compound muscle material is coarse, bond stress is strong, be easy to and bondings such as other objects such as concrete, thereby bond stress of the present utility model is also better.Reinforcing bar is a notched bars, and there is rib on the surface, and steel wire diameter is little, and the specific area of side is big, therefore all can be bonding firm with the fibre resin composite bed, and bulk strength is also better.
2. the fiber corrosion resistance and good that adopts in the fibre resin composite bed in the utility model, intensity height, it is the fiber of excellent performance, when fibre or FRP sheet material were formed cellulose/resin composite by resin-bonding as the fibre resin composite bed and by fibre and resin, the resin after the curing was closely knit, intensity is high, good toughness; Be distributed with fibre in the resin; good integrity; resin is not easy to crack; fundamentally stopped the generation of steel corrosions; give steel with enough protections, overcome the fragility of FRP and the shortcoming of steel easy-to-rust, compound muscle material durability of the present utility model like this has clear improvement; the life-span significant prolongation of structure, the later period maintenance cost is also low.
3. the volume content of fibrous material of the present utility model and fibre resin composite bed thickness, fiber and resin has designability.

Fig. 4 is the another kind of external structure schematic diagram of the utility model.
The specific embodiment
A kind of compound muscle material comprises; The muscle material is coated with fibre resin composite bed 2 in the outside of muscle material, in the present embodiment, the muscle material can adopt following two kinds of forms: (1) referring to Fig. 1, the muscle material is a round bar 1, is provided with projection 11 on the surface of muscle material, this projection 11 can adopt strip bulge, as: projection 11 is selected screw thread for use; (2) referring to Fig. 2, the muscle material is a tendon 3, and when the muscle material was tendon, tendon and fibre resin composite bed were combined with each other, and the fibre resin composite bed is overlying on the surface of reinforcing bar, steel wire or the steel tendon (rope) etc. of forming tendon, has formed complex.Present embodiment also can adopt following technical measures, that is: the external surface spiral at fibre resin composite bed 2 is wound with the compound rope 4 of fibre resin, and the external surface of fibre resin composite bed 2 is corrugated; Be provided with gravel 6 on fibre resin composite bed 2 external surfaces, the gravel 6 on fibre resin composite bed 2 external surfaces can adopt the method for blasting treatment that gravel is arranged on fibre resin composite bed 2 external surfaces.The cloth product that above-mentioned fibre resin composite bed 2 can adopt market to sell, and can be compound in the external surface of muscle material by structure glue, the cloth that the compound rope 4 of above-mentioned fibre resin also can adopt market to sell is made.
