Abstract
The utility model discloses a prefabricated tube concrete member, particularly a prefabricated aramid fiber reinforced tube concrete member, which is composed of two matched semicircle thin plates, the length of each of which is from 1 m to 10 m, the thickness of each of which is from 3 mm to 8 mm and the diameter of each of which can be determined according to the actual diameter of the reinforced post. By the additional specific aramid fiber hoop or anchoring device, the two matched semicircle thin plates are connected closely and are wrapped out of the post, and thereby, the protection for the post is completed. The ductility of the post is increased by the utility model which has the advantages of energy absorption performance and shock absorption performance, the steel bar concrete of the inner post is free from chemical corrosion, unexpected impact and dynamic load can be prevented, and thereby, the shock resistance of the structure is enhanced.
Description
Technical field the utility model relates to a kind of prefabricated pipe concrete member, particularly a kind of prefabricated aramid fiber reinforcement pipe concrete member.
Widely used prefabricated pipe concrete member in the background technology civil engineering because its material itself and execution conditions are limited, exposes many shortcomings that are difficult to remedy in the middle of using.Along with the rise of modern new material technology and going deep into of dependency structure theoretical research, make prefabricated pipe concrete reinforcement members with some new materials and in the civil structure field, furtherd investigate.
At present, the steel pipe concrete member is widely used in the civil construction project always, but practice shows, there are many problems in actual applications in this member, existing material itself, also there is the execution conditions influence to be caused, be embodied in following 4 points: (1) steel pipe is peeled off often with inner steel bar concrete, make the steel pipe concrete member can not form a good whole stress system, thus the application life of having reduced member; (2) steel pipe self subjects to various chemical attacks outside, and then influences inner steel bar concrete, destroys its intensity; (3) construction is frequent, and the construction plant is restricted, causes later maintenance or retrofit work difficulty.(4) the steel pipe concrete member is because of its construction and maintenance difficulty, and actual is to have prolonged the duration, causes investment cost to increase indirectly.
In order to solve this present situation, some are introduced gradually as the new material of prefabricated units reinforcement, opened up the frontier that civil structure research is used as fibrous material, more representational have glass fiber, a carbon fiber, but it is bigger that the two all exists material fragility, the shortcoming of anti-severe impact poor performance.
Summary of the invention is in order to remedy the defective that exists in the existing product, the utility model discloses a kind of prefabricated aramid fiber reinforcement pipe concrete member, this member adopts aramid fiber in the hoop direction, and axial direction adopts carbon fiber or aramid fiber, manufacture craft is simple, easy construction, the duration is short, in the ductility that has improved post simultaneously, prolonged the whole service life of member again, but also have energy absorption capacity and damping property, can resist unexpected the impact and dynamic load, thereby strengthen the shock resistance of structure.
Aramid fiber reinforcement prefabricated pipe concrete structure provided by the invention, combine by two aramid fiber semicircle thin plates, the length legislations of this semicircle thin plate is in the 1-10m scope, needs according to design and construction, make the semicircle thin plate of different-diameter during manufacturing in advance, lamella thickness is 3-8mm, and then select supporting aramid fiber semicircle thin plate up to specification, every pair of semicircle thin plate is added aramid fiber hoop or special ground tackle, make the semicircle thin plate between the different length classification fix and be combined into whole cylinder by aramid fiber hoop or the binding of special ground tackle, be wrapped in institute's reinforcement post around, play corresponding strengthening action.
Compared with prior art, the present invention has following tangible beneficial effect:
1. according to the post of different size, press different-diameter, the prefabricated supporting semicircle aramid fiber thin plate of different length selection, the density of aramid fiber is less than 1/5 of steel, and thickness is in light weight about 3-8mm, easily installs, and it is simple and easy to construct, and need not the heavy equipment facility.
2. adopt the combination of two semicircle thin plates to do packaged tube, safeguard, transformation and dismounting be all very simple and easy in the future.
3. the intensity of aramid fiber is 5 times of steel, and stress-strain relationship is linear, and it is little to play mould, and strain is big, has increased the bearing capacity of pipe concrete.
4. aramid fiber possesses good resistance to corrosion, does not have the reinforcement corrosion problem, and useful life period is long, and later maintenance is very simple.Cut off contacting of inner steel bar concrete and external environment condition simultaneously, prevented the erosion of extraneous water, air and chemical element.
5. aramid fiber is non-conductive, reduces potential electromagnetism danger, simultaneously, effectively with electrical environment isolation on every side, prevents the electrochemical corrosion of inner reinforcing bar.Can be widely used in the electromagnetization environment such as subway, industrial premises.
6. the easy application of aramid fiber can be allocated different scene colors, beautiful environment according to different occasions.
7. aramid fiber possesses good energy absorption capacity and damping property, can resist unexpected the impact and dynamic load, has strengthened the shock resistance of structure.
Appended drawings is that two aramid fiber semicircle thin plates are combined into aramid fiber pipe concrete structure elevation:
Among the figure: 1. semicircle aramid fiber thin plate 1 2. semicircle aramid fiber thin plates 2 3. aramid fiber hoops
4. aramid fiber pipe concrete inwall 5. semicircle thin plate assemble lines
The following specific embodiment of the specific embodiment by this aramid fiber pipe concrete member of description of drawings
According to the design and construction needs, respectively two of the pairing that will make semicircle aramid fiber thin plates (1) and (2) be wrapped in post around, make two semicircle thin plate inwalls (4) be close to the surface of post by adding specific aramid fiber hoop (3), two semicircle thin plates are located close proximity at its assemble line (5), thereby finish the reinforcement of aramid fiber pipe concrete member coupled columns.
Embodiment 1:
A kind of aramid fiber reinforcement prefabricated pipe concrete member, being designed to semicircle thin plate length is 5m, lamella thickness is 5mm, selects the thin plate diameter according to the diameter of institute's reinforcement post.By aramid fiber hoop or special ground tackle make it to be close to post around.Than steel pipe concrete with do not manage the post of concrete structure, adopt the post of this aramid fiber pipe concrete structure that very big enhancing has not only been arranged on ductility, and shock resistance also is greatly improved.
Embodiment 2:
A kind of aramid fiber reinforcement prefabricated pipe concrete member is designed to the reinforcement to old post, and semicircle thin plate length is 8m, and lamella thickness is 7mm, selects the thin plate diameter according to the actual diameter of old post.By aramid fiber hoop or special ground tackle make it to be close to post around.Through the pillar after the reinforcement, weight bearing power is greatly improved than before.
