Description
Technical field
The present invention is the relevant technology that aging or unsubstantial concrete structure are repaired, reinforced, especially tightening and the measurement of torque capacity (TORQUE) of the screw at the two ends by being installed in the tension force material guaranteed that tension force is correct, the invention that is easy to repairing, reinforcement material and the technology of relevant concrete construction again is installed.
Background technology
As everyone knows, the various concrete constructions of using as civil construction are subjected to the infringement of various contaminant water such as climate change and seawater, underground water, rainwater and hazardous substances, quality of concrete can degenerate gradually, also aging phenomenon can occur.
Therefore, concrete structure will periodically carry out safety inspection, if check result does not reach the intensity of requirement or has and abnormally peels off, peels off, breaks etc. during phenomenon, repairing, the reinforcement that should gain in strength, improve load forces.
The technology that relevant concrete structure is repaired, reinforced, Korean Patent Publication No. 10-1999-No. 024271 and 10-20020039389 number introduction was arranged once.
These formerly technology utilize the stainless steel cloth of barrier shape to promote the load forces of concrete structure, stainless steel cloth plays action of steel bars, utilizes reinforcing the gluing and property generation consolidation effect with mortar that forms surface course.
Formerly the reinforcing principle of technology is identical with original concrete establishment principle and organizational styucture system for these, just replaces reinforcing bar with new reinforcement material-stainless steel cloth, forms thickness with reinforcing mortar.That is,, the steel concrete that weakens and overload aging in order to reinforce replaces reinforcing bar with stainless steel cloth, and mortar is sticking and on concrete pier or sheet material with reinforcing, and improves the resistance of reinforcing bar.
But, the above-mentioned technology basis of utilizing gauze wire cloth to reinforce aging concrete structure is judged the quality of quality attached to the tensioning state of the gauze wire cloth in the concrete construction, owing to following reason, can not guarantee tension force and reduce consolidation effect:
1, a coil silk screen is generally 33 on-the-spot tensionings and fixes, and can not guarantee that each bar steel wire all is in tensioning state, pleating shortcoming will occur, does not reach the tension force of requirement, thereby reduces consolidation effect.
When 2, constructing on the coarse surface of damaging of concrete, gauze wire cloth can be pleating, lowers consolidation effect.
3, the produced in lengths of gauze wire cloth about with 30M come out, block use by the length of construction at the scene, it is fragile that the phenomenon that will occur connecting in order to reduce consumption, the position of blocking like this can become, and tension force also can die down.
The part of being oppressed by tensioner when 4, constructing, gauze wire cloth two ends 1-2M can not carry out tensioning, and after tensioner was removed, it was impaired tension force to occur.
Also have, utilize the technology formerly that gauze wire cloth is repaired, reinforced concrete is built, come out in plant produced with unified specification, can not increase and decrease the reinforcing amount at each position according to the purpose of repairing, reinforce, and during problem such as building generation crackle, fragility, to lay reinforcement material in whole cross section, very uneconomical.
Have, cancellated steel wire can be sagging because of deadweight again, so carry out relatively difficulty of following reinforcing as the building in arch cross sections such as tunnel.
At last,,, need do cutting separately as skew bridge, curve bridge etc. if not the reinforcing face on plane, like this can be very loaded down with trivial details, slow.
Korean Patent Application No. 10-0311054 once introduced the repairing and reinforcing technology of concrete structure, promoted the withstand load power of concrete construction on the surface of carbon fibre, glass fiber or aramid fibre with containing silicon silk or garnet fiber reinforcing material.
This concrete structure that utilizes fiber to do reinforcement material is repaired, reinforcement process has many good qualities: light, the cohesive of mortar is good, tension force is big, do not corrode, construction easily when increasing and decreasing the reinforcing amount at each position according to the purpose of repairing, reinforce.But the repairing of the above-mentioned concrete structure that utilizes fiber reinforcing material, reinforcement process have following problem because of the material behavior of himself:
Though the tensile strength of 1 fibrous material is very strong, when being subjected to moment impact, destroy easily, can not bring into play anti seismic efficiency;
The refractoriness of 2 aramid fibres (ARAMID FIBER) is low, when breaking out of fire, fiber has the danger of being burnt, and mortar is heat insulation so construction the time also needs to carry out, surperficial refractory process etc., can increase cost;
3, the end of fibrous material is inserted into the stainless steel and iron carriage, fixes with nailing or connecting line, and the danger that drops out or destroy from fixed position is arranged;
When 4, constructing surface imperfection,, can reduce consolidation effect if fibrous material is provided with not directly;
5, the above fiber roll of long diameter or 15M, carrying and keeping are very difficult, when bending to a certain degree, can not use, and therefore too much connecting portion can occur and tension force can not transmit, problem such as skid;
6, the initiation intensity between fiber roll and the mortar is uncertain, and the cross section of fiber roll is wide, can not form firm bonding force with old concrete.
Repair with concrete structure, reinforce relevant technology, also have following example: Korean Patent Publication No. is utilized the structure of grill-shaped gusset plate for 10-2001-0028610 number, 10-1997-0058912 concrete strengthening epoxy resin board and manufacture method thereof, 10-2001-utilizes for No. 0054105 the carbon foundation to promote the technology of building loading power, 10-2001-utilizes steel wire tension bottom of device sheet material reinforcement process for No. 0107897, especially the fire-resistant reinforcement process of patent No. 10-2002-0075746 landfill mild steel line, build Ministry of Communications and build the adding groove technology that new technology is utilized carbon element plate reinforcing building loading power for No. 295, build Ministry of Communications and build the building strengthening technology that new technology is utilized trapezoidal carbon element rod of landfill and concave-convex surface shape carbon fibre gusset plate for No. 351.
But there is following problem in above-mentioned technology formerly:
Above-mentioned publication number utilizes for 10-2001-0028610 number the structure of grill-shaped gusset plate and 10-1997-0058912 concrete strengthening that the problem that had in the past existed is arranged with epoxy resin board and manufacture method thereof.Sagging the time, merely prevent sagging when losing durability with stickiness; The structure of connecting portion is inaccurate; Require the flatness of contact surface precision, thereby raise the cost and prolong the engineering time.
Especially, 10-1997-0058912 number, use the organic material epoxy resin board different with the steel concrete rerum natura, the time has been grown and interfacial separation can occur, come off, consolidation effect reduces, the burned problem of organic material during breaking out of fire.
Utilizing for 10-2001-0054105 number the carbon foundation to promote the technology of building loading power, 10-2001-0107897 number utilizes the bottom sheets reinforcement process of steel wire tension device that following defective is arranged: reinforcement material is overweight and building deadweight that cause increases and bottom space dwindles, and exposing for a long time of building can produce problems such as damage, fracture.
Especially 10-2001-0107897, L fixed area and central T type carriage are exposed, the center is outstanding, the fracture of chronicity steel wire and slow distortion can fluff, need tensioning again, with oil pressure tension equipment tension steel wire, constructional difficulties, fastening devices is outstanding, and steel wire and pipeline expose and cause that bottom space dwindles and bad order.
Also have, the fire-resistant reinforcement process of patent No. 10-2002-0075746 landfill steel flexible cord, build Ministry of Communications and build the reinforcing building internal loading that new technology utilizes the carbon element plate for No. 295 and add groove technology, build Ministry of Communications and build the building strengthening technology of the carbon fibre gusset plate that new technology utilizes trapezoidal carbon element rod of landfill and concave-convex surface for No. 351 at sheet material or bridge pier grooving landfill, constructional difficulties reduces economy.
Especially build Ministry of Communications and build new technology No. 295 and No. 351, sagging the time, merely prevent sagging with stickiness when losing durability; Use the organic material different No. 295: carbon element epoxy resin with the steel concrete rerum natura, No. 351: carbon element rod or carbon element plate epoxy resin board, time has been grown and interfacial separation can occur, come off, consolidation effect reduces, the burned problem of organic material during breaking out of fire.
