Abstract
The utility model discloses a composite carbon fiber threaded bar. The composite carbon fiber threaded bar comprises a threaded bar body, and is characterized by further comprising a metal alloy layer, a carbon fiber layer, a threaded part and a second carbon fiber layer which are sequentially arranged on the outer side of the threaded bar body. The composite carbon fiber threaded bar has the benefits as follows: the composite carbon fiber threaded bar is not only light in weight, convenient to transport, unlikely to corrode, convenient to store and relatively long in service life, but also has greater strength than a threaded steel bar.
Description
Technical field
The utility model relates to a kind of Novel threaded muscle, is specifically related to a kind of carbon fiber reinforce plastic twisted steel.
Background technology
At building field, twisted steel is conventional reinforcing material, is widely used in the civil works construction such as house, bridge, road, is mainly used in the reinforcing of support, scaffold and the reinforcing of mixed earth.A kind of as high-performance fiber, carbon fiber is most important reinforcing material in composite material, at building field, obtains extensive use.
Existing twisted steel mostly is screw thread steel muscle, exists quality to be difficult for greatly transportation, the easy deficiencies such as affecting the life-span that is corroded.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of NEW TYPE OF COMPOSITE carbon fiber twisted steel.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
Carbon fiber reinforce plastic twisted steel, comprises twisted steel body, it is characterized in that, also comprises: the metal alloy layer, carbon fiber layer, threaded portion, the second carbon fiber layer that are successively set on above-mentioned twisted steel body outside.
Further, the thickness of above-mentioned carbon fiber layer is greater than the thickness of metal alloy layer, and the thickness of above-mentioned metal alloy layer is greater than the radius of twisted steel body.
Further, above-mentioned twisted steel body is reinforcing bar.
Further, above-mentioned metal alloy layer is titanium alloy layer; Above-mentioned threaded portion is titanium alloy threaded portion.
Further, above-mentioned carbon fiber layer is the aramid fiber cloth around above-mentioned twisted steel body outside 10 ~ 15 circles; Above-mentioned the second carbon fiber layer is the carbon fibre initial rinse fabric around outside, threaded portion 1 ~ 2 circle.
Usefulness of the present utility model is: carbon fiber reinforce plastic twisted steel not only quality is light in transportation, and not perishable, be convenient to deposit there is longer application life, and in intensity not second to the intensity of screw thread steel muscle.
Accompanying drawing explanation
Fig. 1 is that the utility model is gone out the sectional view of the second carbon fiber layer.
The implication of Reference numeral in figure:
1-twisted steel body, 2-metal alloy layer, 3-carbon fiber layer, 4-threaded portion,
The radius of a-twisted steel body, the thickness of b-metal alloy layer, the thickness of c-carbon fiber layer.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Carbon fiber twisted steel as shown in Figure 1, comprising: twisted steel body 1, be successively set on metal alloy layer 2, carbon fiber layer 3, threaded portion 4, the second carbon fiber layer (not shown) in twisted steel body outside.Be that twisted steel body 1 outside is provided with metal alloy layer 2, metal alloy layer 2 outsides are provided with carbon fiber layer 3, and carbon fiber layer 3 outsides are provided with threaded portion 4, and outside, threaded portion is provided with the second carbon fiber layer.
The thickness c of carbon fiber layer 3 is greater than the thickness b of metal alloy layer 2, and the thickness b of metal alloy layer 2 is greater than the radius a of twisted steel body 1.As a kind of preferred version, twisted steel body 1 is reinforcing bar, and in order to reduce as much as possible the weight of reinforcing bar, the radius a of twisted steel body 1 is as much as possible little; Metal alloy layer 2 is titanium alloy layer, and threaded portion 4 is titanium alloy threaded portion, and titanium alloy quality is light, toughness is large, and titanium alloy layer plays transitional function between reinforcing bar and carbon fiber layer; Carbon fiber layer 3 is that aramid fiber cloth is mainly used in strengthening the intensity of fine steel rib, so the thickness of carbon fiber layer 3 is large as much as possible around the aramid fiber cloth of twisted steel body outside 10 ~ 20 circles; The second carbon fiber layer is that carbon fibre initial rinse fabric mainly plays the effect of retaining thread portion 4 around the carbon fibre initial rinse fabric of outside, threaded portion 1 ~ 2 circle, and increases surface strength and corrosion resistance.The radius a of twisted steel body 1 is 3 ~ 4mm preferably, and the thickness b of metal alloy layer 2 is 4 ~ 5mm preferably, and the thickness c of carbon fiber layer 3 is 5 ~ 6mm preferably.
Carbon fiber reinforce plastic twisted steel of the present utility model increases titanium alloy layer and carbon fiber layer in very thin reinforcing bar outside, substitute as original screw thread steel muscle, greatly reduce the quality of original screw thread steel muscle, do not lose again its original intensity, improved engineering efficiency.
More than show and described basic principle of the present utility model, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
