Description

Tension material dismantling device for anchor method {to pieces equipment for anchor a method of construction use}

The present invention relates to a tension member dismantling device used in the anchor method, the anchor method is a method used to reinforce the soft ground in civil works, such as earthquake construction, stabilization of the tunnel shaft, stonework and retaining wall reinforcement. After drilling the ground by inserting the inner body consisting of grout hose and tension member into the drilled hole and injecting grout through the grout hose, and when the injected grout is cured with the lower body, the tensioned material is stretched by using a tensioner on the cured grout and ground. As a method of reinforcing the soft ground by tensioning, it is a method commonly used in civil engineering. However, the application of anchor method in urban construction has the advantages of effective construction management and shortening of air. However, the construction of drilling equipment and drilling equipment is due to the hypothesis of the tensile material whose strength is about 6 times higher than that of general reinforcing bar in subsequent construction of adjacent areas. Loss and air delay occurs. Therefore, the removal anchor used to remove the tension member in accordance with the construction process after completion of the excavation work is used, which is the tension member dismantling device used in the anchoring method.

The tension member dismantling apparatus used in the conventional anchor method is the head 300 is inserted into the dismantling wedge 200 of the coarse-shaped dismantling wedge 200 is inserted into the tension member 100, as shown in Figure 1 ), The support plate 400 is inserted into the upper annular groove of the dismantling wedge 200 to support the distal end of the dismantling wedge 200 and the tension member 100, and the wedge cover 600 into which the dismantling screw 500 is rotated and inserted. have. 1 is a state in which the tension member 100 is tensioned using a tensioner in the anchor method. After cutting the tension member 100 in this state and rotating the tension member 100, the dismantling screw 500 in contact with the end of the tension member 100 is inserted into the groove of the wedge cover 600 as shown in FIG. And when the dismantling wedge 200 releases the restraint of the tension member 100, the tension member 100 is pulled to complete the dismantling of the tension member 100.

However, when the tension member dismantling apparatus used in the conventional anchoring method rotates the tension member after the cutting of the tension member 100, only the tension member 100 is idled in the support plate 400 at which the end of the tension member 100 is in contact with the disassembly screw 500. There is a case that can not rotate, the tensile force generated during the tension of the tension member 100 is acted as a strong repulsive force when the removal of the tension member 100, the dismantling screw 500 is to hit the groove of the wedge cover 600 to the wedge screw ( 500 is stuck in the groove of the wedge cover 600, and when the tension member 100 is rotated causes only the tension member 100 is idling, a separate process of rotating the tension member 100 after cutting the tension member 100 And problems such as the need for equipment.

In addition, the part which prevents the tension member 100 and the head 300 from spiral coupling (A) is often buried in construction delay or underground, and water penetrates into the blocking part during the grout curing period, and rust is frequently formed inside. When removing the tension member, a problem occurs that becomes a factor of failure.

The present invention has been made in order to solve the above problems, the tension member 10 is inserted into the hook-shaped hook jaw 40 is formed in the upper portion of the support plate 30 for supporting the inserted end of the tension member 10 It is mounted inside the dismantling wedge 20 and the wedge cover 70, and the stepped rod 80 inserted into the locking jaw 40, the spring 90 inserted between the dismantled wedge 20 and the stepped rod 80, Composed of a wedge cover (70) and spirally coupled to the head 60 is a cockle cone (55) inserted into the tension material 10 is tightly coupled to prevent the occurrence of rust during construction delays or underground buried, tensile tension material (10) By using the repulsive force generated during the cutting of the tension member 10 is pushed up the dismantling wedge 20 to the stepped rod 80, the locking step 400 and the stepped rod formed on the disassembled wedge 20 This naturally combined tension member removal device for anchoring method that can remove the tension member 10 without the need for additional process And the gongham for that purpose.

Hereinafter, the configuration and the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 is a full exploded perspective view of the present invention, the support plate 30 and the support plate 30 is inserted into the annular groove of the dismantling wedge 20 to support the end of the tension member 10 is inserted and inserted into the tension member 10 By forming an annular locking jaw (40) on the upper portion of the dismantling wedge (20). At this time, the dismantling wedge 20 is separated into three pieces and binds with a rubber ring 50 to form a cockle cone.

In addition, the dismantling wedge 20 configured as described above is inserted into the head 60. At this time, the dismantling wedge 20 of the pinch type inserted into the head 60 serves as a wedge when the tension member 10 is tensioned, and the inner surface is helically formed so that when the tension member 10 is tensioned, The tension line 10 serves to prevent the departure.

In addition, the lower portion of the head 60 into which the tension member 10 is inserted is blocked with a cockle cone 55 made of plastic. In this case, the cockle cone (55) is simply installed by inserting the tension line 10, and then pushed in the head 60, the waterproof effect to prevent the water penetrates into the tension material dismantling device and thereby prevents the role of rust prevention do.

In addition, the head cover 60 is spirally coupled with the wedge cover 70 is formed in the inner space with a diameter and depth that can be inserted into the dismantling wedge 20, the stepped rod 80 is mounted on the upper end of the inner surface. At this time, the stepped rod 80 'of the stepped rod 80 is located directly above the locking step 40 so that the dismantling wedge 20 can be coupled to the stepped 80' of the stepped rod 80 when moved upward. At this time, the diameter of the inner space of the wedge cover 70 is the stepped rod 80 and the disassembled wedge even if the disassembly wedge 20 is opened when the stepped 80 'and the locking step 40' of the stepped rod 80 are combined. It is enough that (20) does not depart.

In addition, the circular spring (90) inserted into the inner space of the wedge cover (70) is easily coupled to the disassembly wedge (20) when the stepped rod (80) and the dismantling wedge (20) are easily cut together after the tension line (10). The inserted tension line 10 serves to prevent the departure.

Figure 4 is a cross-sectional view showing a state in which the tension member 10 is tensioned by the tension member dismantling apparatus according to the present invention as described above is a state in which the tension member 10 is tensioned as much as possible. As shown in FIG. 5, due to the repulsive force generated in the tension member 10, the tension member 10 pushes the support plate 30 that supports the ends of the tension member 10 upward and presses the dismantling wedge 20. Combining the stepped 80 'of the stepped rod 80 while compressing the spring 90 and the dismantling wedge 20 can be easily removed from the restraint of the tensioning member 10, the tension member 10 can be easily removed.

The present invention is not related to rust or strong tensile repulsion, which is a failure factor of dismantling of tensile material in the removal of the tensile material installed in the ground in the anchoring method, and it is possible to remove the tensile material from the dismantling wedge at the same time as the cutting of the tensile wire without additional equipment or process. Is a very useful invention.
