The repair and reinforcement construction method has the characteristics of easy material acquisition and simple and fast construction method. [Previous technology] In recent years, the occurrence of earthquakes at home and abroad has caused considerable loss of life and property even in several large-scale earthquakes. Among them, the collapse of reinforced concrete (RC) buildings has been very serious. Statistics of damage cause identification According to data analysis, during the collapse of reinforced concrete buildings, usually caused by the failure of the pillars as the supporting structure first, the main reason is that the pillars cannot withstand the lateral forces of the earthquake. As shown in the first figure, in terms of the current structure of the reinforced concrete column 9, it is mainly based on the required cross-sectional area of the column, and a plurality of main bars 91 arranged in parallel and spaced vertically in the vertical direction above 15 And tie a plurality of transverse stirrups% at certain intervals around the main reinforcing steel bars 91, and then completely cover the main reinforcing steel bars 91 and the transverse stirrups 92 with a concrete material to form the shape of the column 9 The concrete material provides the rigidity of the building, the main steel bar 91 provides the tensile toughness, and the effect of the transverse stirrup% is 20 Xiao to provide the lateral support of the main steel bar 91, increase the shear strength of the column 9 and the surrounding bundle. force. The analysis of the failure of the column 9 under the force, when the column 9 is carrying a certain axial force and is simultaneously subjected to the lateral force of the earthquake, it is located outside the main steel bar 6 577952 玖, the description of the invention (2) side concrete The material will crack and peel off first, so that the longitudinal main reinforcement 91 and the transverse stirrup 92 are exposed. If the column 9 is continuously stressed, the main reinforcement 91 between the upper and lower adjacent transverse stirrups 92 lacks support or the transverse stirrups. The damage caused by the drop of 92 makes the column 9 break quickly. Therefore, the characteristic of strengthening the resistance of the lateral main steel bars 91 5 against lateral forces is an effective measure to prevent the column 9 from breaking. Therefore, in order to improve the seismic effect of the column, At present, the United States, Japan, and even China have significantly revised the stirrup specifications for seismic design, including reducing the spacing, increasing the tie bar, and strictly requiring hooks, etc., making the combination of the 10 main steel bars and the transverse stirrups in the column body like Grid-like dense to add a more complete containment effect to the main reinforcement. However, the denser the main steel bars and transverse stirrups means that the difficulty in construction of bending steel bars and pouring concrete slurry has increased. Turning back to improving the toughness and bounding forces of reinforced concrete columns, the performance of spiral stirrups is far better than that of horizontal stirrups. As early as in the 1940s, 15 tests showed that the load-displacement curves of the cylinders of the two types of stirrups were almost identical before they reached the strength limit under axial pressure, but when the strength limit was reached, The brittle failure of the horizontal stirrup column occurred almost immediately, while the concrete shell of the spiral stirrup column spalled first, but the concrete column core surrounded by it could still bear the load until the lateral deformation caused the screw 20 When the hoop tendons fall, they can exhibit plastic failure behavior. However, in terms of construction, the bending of spiral stirrups must use special tools, and there are restrictions on the arc configuration. There is considerable difficulty in actual construction, because the stirrups themselves are made of general steel bars. Larger, more difficult to bend 7 玖, invention description (3). So it is no wonder that although the seismic performance provided by spiral stirrups is better than that of ordinary horizontal stirrups, it is rarely used in the column structure of general buildings. In summary, 'increasing the number and density of transverse stirrups, or using spiral stirrups, although it has a positive effect on the seismic resistance of reinforced concrete columns, it adds considerable difficulties in construction, not only construction Costs increase and construction time increases. On the other hand, when the column is damaged by the lateral force of the earthquake, but the internal main steel bar does not produce a buckling phenomenon, it is necessary to have a fast and effective reinforcement method to avoid further damage to the structural members. For all methods of repair and reinforcement of reinforced concrete buildings, it is not possible to instantly and quickly reinforce structural components such as columns, and some methods are even more difficult to design and construct than to rebuild. Therefore, it is the main object of the present invention how to have excellent characteristics like spiral stirrups when constructing or repairing reinforcing structural members, while simultaneously taking into account the requirements for convenient material acquisition and simple and fast construction. [Summary of the Invention] Therefore, the purpose of the present invention is to provide a repair and reinforcement construction method for strengthening a reinforced concrete structure by using a certain tensile strength as a main reinforcing bar to improve the anti-damage performance of the structure. It also has the characteristics of easy material acquisition and simple and fast construction. Therefore, 'the construction method of the present invention for repairing and reinforcing the reinforced concrete JL structure with steel rims' is applicable to the long-reinforced concrete structural members in the building. The structural members form the opposite in the length direction. And the structural member has a plurality of juxtapositions from the first end to the second end: 577952 发明, the description of the invention (4) the main reinforcing steel that extends and the concrete material covering the main reinforcing steel; the construction method includes the following steps: first The main steel bar of the structure is exposed. Take a steel cable with a certain tensile strength to fix one end of the cable to one of the main 5 steel bars near the first end. Eighth, the steel cables are spirally wrapped around the main reinforcing bars in a spiral manner toward the first end portion to surround the main reinforcing bars. Then fix the other end of the steel cable to one of the main steel bars. Thereafter, to the combination of a plurality of templates 10 define a plasma space surrounded by the main reinforcement of irrigation and the like. A grout is filled into the grouting space to completely cover the main reinforcing bars and steel cables. Finally, the formwork is removed after the concrete slurry has solidified and hardened. [Embodiment 15] the invention and other technical contents, characteristics and effects, in the following detailed description with reference to the drawings, one preferred embodiment will be apparent to understand. Refer to the second figure 'a preferred embodiment of the steel cable repair and reinforcement construction method of the reinforced concrete structure of the present invention is illustrated by the repair of a reinforced concrete column 20' The application is when the column is damaged and the surface concrete Under the condition that cracks have not occurred or there is no slight buckling, the main steel bars inside the column are not bent outward at this time, and the column is reinforced immediately. Among them, the pillar 1 is formed in the vertical length direction with a first end portion 1091 577952 接近, a description of the invention (5) and a second end portion 102 located above, and the pillar portion is For example, the general clay structure has a plurality of main reinforcing bars U extending side by side from the first end 101 to the second end 102, a horizontal box reinforcement 12 surrounding the main reinforcing bar u, and a filler for covering these. Concrete material for main reinforcement 11 and stirrup 12. 5 The steps of the construction method of the present invention are as follows: First, because the outer surface of the column 1 has been damaged, it is in the column! Several temporary support structures 2 such as steel columns are erected on the side to reduce the load of the column and prevent continuous damage. Then, the cracked surface concrete of column 1 is removed with civil appliances, so that the main body inside the column i Reinforcement U and box reinforcement U were exposed to the outside. At this time, the number of main tendons can also be increased by means of planting tendons as needed. θ as shown in the third to fifth figures 'take—a steel cable with tensile strength, in this example, a straight wire is used; ^ 6 mm steel wire 3', and the steel cable 3 is twisted with several plain wires 30. It is made into strands and twisted from multiple strands of plain wires, so that the end of the steel cable 3 is fixed on one of the main 15 steel bars close to the first end of the first end below the column i. The fixing method It is adopted that—the first clamping member 41 and the second clamping member a can be caused by locking—the end of the steel cable 3 is passed around the main reinforcing bar u to form a ring-shaped end 31 around the main reinforcing bar. Then, by locking the first clip 41 and the second clip 42 of the clamp box 4, the steel gauge line 3 located between the first lost piece 41 and the second clip is lost 20, and the annular end portion 31 is fixed. Without leaving the main reinforcing bar u. Of course, the fixing method using the clamp 4 is not unique, as long as it can fix the end of the steel gauge wire 3, any of the fixing methods u can be fixed. 10 577952 Rose, description of the invention (6) Then as shown in the fifth figure (In order to facilitate the description of the repair and reinforcement of the present invention, the original stirrup 12 is not shown in the figure), the steel cable 3 is spiraled from the direction near the first end portion 101 to the second end portion 102 of the column 1 In this way, the main steel bars 11 are wound around the main steel bars 11 at intervals of 5 to 7 cm. In actual operation, the spacing distance between the upper and lower adjacent circles of the main steel bars 11 surrounded by the steel cable 3 can be appropriately adjusted according to the degree of reinforcement ', and the steel cable 3 can be appropriately applied with a proper tensile force to maintain the surrounding Tension of the steel cable 3. After that, the other end of the steel reed wire 3 is also fixed to one of the main reinforcing bars 11 in the same manner as the clamp 4 is locked 10. As shown in the sixth figure, a plurality of templates 5 are combined to surround the bare main steel bars 11 and the steel cables 3 after being bound to define a grouting space 50, and a space 5 is reserved. The connected grouting port 51, because this part is a mature technology of general concrete grouting engineering, will not be described in detail here. Finally, the concrete is filled into the filling space 50 through the filling hole 51 to completely cover the main reinforcing bars 11 and the steel cables 3. After the concrete slurry is solidified and hardened, the formwork 5 is removed to complete the repair of the column 1. The reason for using steel cable is mainly because of its excellent resistance to 20 sheets. Since the steel wire is a combination of multiple plain wires, the defects of each plain wire are scattered over the entire length of the overall steel cable, so the impact of load damage on the overall steel cable is small. It can be said to be very safe. In addition, although the plain wires are twisted with each other, they are independent of each other. If they suffer external damage, only 11 577952 发明, invention description (7) is that the strength of the cross section of the separate plain wire is reduced, which is more normal. For steel, no

In addition, in addition to the above-mentioned mechanical properties, steel cables have a softer bendability than ordinary stirrups. It is also an important consideration, making steel cables much easier to use than ordinary stirrups during construction. No special f-curve tools are required. In addition, since the steel cable is twisted from plain wires, the surface of the steel cable is formed with a lot of depressions and openings. Therefore, the grip between the concrete material and the steel cable is also very good. The slub-like surface of general steel bars has better grip strength. 15 In order to verify that the post-reinforced steel cylinder has better resistance to deformation, the inventor conducted a series of tests at the National Earthquake Engineering Research Center. The following only summarizes a standard test body and the steel cable reinforcement Comparison of test subjects on data. Among them, the standard specimen is a steel 20-reinforced concrete column with a rectangular cross-section designed in accordance with the old specifications. The cross-section of the column is 50 cmX 50 cm and the height is no cm. The main reinforcement is made of 12 bars without any truncation and the yield strength is 4200kg. / cm2 # 8 steel bar, transverse stirrups are made of # 3 steel bar with strength of 2800kg / cm2, and are arranged at a height of 40cm, concrete 12 577952 玖, description of the invention (8) strength is 210kg / cm2, the foundation of the column The width is 180 cm, the length is 245 cm, and the thickness is 74 cm. The same concrete material is arranged and infused above and below and around it with # 8 steel bars at 11 cm intervals. The test is to apply an axial force of 52.5 tons to simulate the static load of the cylinder, and another 5 hydraulic actuator acts laterally on the cylinder to simulate the lateral force of the earthquake. After the anti-load test coating damage up until the cartridge, displacement of the abscissa, the ordinate is the lateral force results in the following data. ο 11 (NPOSIOlcdq 5 11

In addition, from the comparison of the hysteresis loop of the standard test specimen and the hysteresis loop of the test specimen after repair, it can be seen that the hysteresis loop of the test specimen after repair is obviously fuller, which shows that the repaired specimen is effective in dissipating energy The effect is also better. This shows that the reinforced concrete columns repaired and reinforced by steel cables have indeed greatly improved their ability to resist lateral forces without damage. To sum up, the steel cable repair and reinforcement construction method of the present invention with the reinforced concrete structure has the following advantages: 1. High bundle strength: due to the processing of steel wire and other wires, its resistance is 14 577952 发明, description of the invention (10) The strength can be as high as 8000kg / cm2. Although the strength of the steel cable varies with the material and processing process of the plain wire used, it is generally higher than the damage strength of ordinary steel bars or steel, and the overall The strength variability is small, so when it is the main reinforcement of the spirally bound cylinder, its effect is like the spiral ribs, which can greatly improve the ability of the structure to resist earthquakes and deformation. Second, the construction is fast and easy: because the steel cable has the flexibility of being easy to bend, it can be carried out manually without special tools when surrounding the main steel bar, and the fixing is also quite simple, unlike the horizontal stirrups or even spiral hoops. The ribs need special tools to bend or even have to be welded, and the construction is naturally fast. In addition, another advantage of the flexibility of the Li 10 Xiao'e line is that it can be freely bent with the terrain and features of Shi Yu ', as long as there is a small gap to pass through, Shi Wang can be performed, which is not limited to the construction site and surroundings. The influence of the building structure, for example, the column connected to the wall, as long as the connection between the column and the wall creates a working space through which a steel cable can pass. '15 2. Easy material acquisition. Since steel cables are already standardized and widely used materials in the market, the ease of real-time reinforcement construction is also an important factor in increasing the speed of the project. 4 Fetching 4. Low cost ... Based on the use of steel cables and the valley's ease of material acquisition, the overall construction cost can be reduced relatively. Therefore, using the known construction method of this month, whether it is permanent or temporary The structure of sex reinforces a cost-effective method of construction. # Further, because of the pillars of the structure under the old building regulations, due to the lack of stringent rib construction requirements or insufficient length of column reinforcement at the time, although temporarily 15 577 952, the invention description (11) was not earthquake The lateral force destroys but has potential danger, and the pillar can also be reinforced in the manner of the present invention. As shown in the seventh figure, taking a reinforced bar with insufficient cross-sectional area but complete structure ✓ as an example, it originally had a plurality of old main bars 6 1, 5 and 5 surrounding these main bars 61 The old stirrup 62 and the old concrete material 63 covering the main reinforcing bars 61 and the stirrup 62. When expanding the cross-sectional area of the original column as a reinforcement, first of all, because the column is not damaged, the concrete material 63 does not need to be completely removed, and its surface only needs to be roughened (that is, a non-smooth surface of the tank is formed). Then, a new main steel Mu is planted around the column according to the planned enlarged cross-sectional area of 10f. (At present, the technology of planting tendons on the market is a mature technology with a certain anchoring strength, and will not be repeated here. ), And using the same construction method just described, a steel cable 3 is spirally wound around the bundle and fixed on the new main steel bars 11, and then a plurality of formwork are combined, new concrete slabs are poured, and concrete After the slurry is hardened, the formwork is removed, so that the cross-sectional area of the original 15 column can be enlarged to achieve the purpose of strengthening its structural strength. However, the above are only the preferred embodiments of the present invention. Although it will be described using reinforced concrete columns and steel cables as examples, those skilled in the art can naturally infer that it can be applied to The reinforcement of the reinforced concrete placket body is not limited to the steel-lane line, as long as it has a certain tensile strength and can be freely 20, bending materials can also be applied. In addition, this cylinder repair and reinforcement method also eliminates the need to repair and reinforce the entire cylinder from the first lower end to the second upper end, and can selectively repair the first or second end. Therefore, the scope of the implementation of the present invention cannot be limited by the foregoing embodiments, that is, those who apply for the present invention in accordance with the present invention (16), the description of the invention (12), please refer to the patent scope and the description of the invention. , All should still fall within the scope of the invention patent.
