The purpose of this utility model then is the problem that exists at above-mentioned prior art, and a kind of technical misgivings of any preservation of not only at room temperature not having are provided, more the unidirectional fibre reinforcement paster that can cut arbitrarily with the demand work at use position.

The purpose of this utility model can reach by following measure:

A kind of unidirectional fibre reinforcement paster is characterized in that: a non-woven or claim to cover with paint, lacquer, colour wash, etc. on the base material of fibrous paper or point is sprayed with thermoplastics type's adhesive-layer, and carbon, glass fiber bundle and base material are made the hot-rolling pressure be bonded to one; With thermoplastics type's non-woven be adhesive-layer directly with carbon fiber, glass fibre, Ke Weila fiber or mutually the high-strength chemical-fibre dimension bundle of shuffling surpassing non-woven or claiming the temperature hot-rolling pressure more than the fibrous paper fusing point being bonded as one; So, can borrow non-woven or claim that fibrous paper is fixed on certain position with carbon fiber bundle, and become a kind of reinforcement paster, then work as cement structures thing or reinforcing bar works and meet damage, maybe to do the reinforcement in advance of stress concentration point, just after the reinforcement paster can being laid in ad-hoc location according to stressed or reinforcement direction, cover with paint, lacquer, colour wash, etc. resin, and make resin fully be evenly distributed between fiber fines, treat just to form a high specific rigidity behind the hardening of resin, the reinforcement material of high specific strength or repairing material, closely combine, thereby a kind of rustlessization is provided with cement structures thing or bone structure thing stickup just, the reinforcement of light weight and high capacity energy.

The utlity model has following advantage:

1, carbon fiber bundle 30 of the present utility model (fibre bundle 50) itself is a kind of material of suitable light weight, for appending to the installing of carrying out reinforcement on the works, can say the increase of works burden itself very little.

2, carbon fiber bundle 30 of the present utility model (fibre bundle 50) itself is a kind of non-fine material that belongs to, not easy rustingization not only, for expose to the sun and rain and variations in temperature all more in the past rigidity reinforcement more excellent performance is arranged.

3, reinforcement paster of the present utility model does not need the existing structure thing to be done the construction procedure of any brill lock in the use again, makes the simplicity of construction improve.

4, reinforcement paster of the present utility model can directly be carried into the job site, visual situation that when participating in the cintest need reinforcement cuts, not only need not any previous operations, and this reinforcement paster can preserve at room temperature all always, overcome existing toughness reinforcement the biggest problem on storing effectively.

Fig. 1 is the cross-sectional schematic of the utility model one preferred embodiment.

Fig. 2 is the cross-sectional schematic of another preferred embodiment of the utility model.

Among the figure:

10 base materials, 20 adhesive-layers, 30 carbon fiber bundles

40 base materials, 50 fibre bundles

Below in conjunction with accompanying drawing the utility model is further described:
