Description

TECHNICAL FIELD [0001] The present invention relates to a wedge separator for an internal fixture of a ground anchor,

The present invention relates to a wedge separator for an internal fixture of a ground anchor, and more particularly to a wedge separator for an internal fixture of a ground anchor, The present invention relates to a wedge separator for smoothly separating a wedge assembly having a tensile member and a wedge assembly from each other when the wedge assembly is detached.

In order to prevent the collapse of the ground near the site which is not excavated in the excavation work for the underground structure to construct the construction and the civil engineering structure, the earth retaining work is carried out, and as a stabilizing means to suppress the soil loss of the incision surface of the soft ground Ground anchors are used.

The ground anchor can be divided into compressive type, tensile type, and acupressure type. The most commonly used tensile type ground anchor has a disadvantage that it can not remove the tensile material. Since the anchoring ground anchor is restrained by the tip end pressure, There is a problem that difficulty arises when removing the tensile material.

In order to solve such a problem, the ground anchor proposed is a ground anchor tensile removal type internal fixing body. The inner fixture is fixed to an anchor hole in the ground, and an underground excavation and an underground structure are constructed. Then, a method of cutting the outer fixture of the tensile material fixed on the belt side of the earth wall is used. The wedge assembly was removed, and the wedge engagement with the tensile material was released, so that the tensile material could be easily removed only by the manpower without using the equipment such as the drawing machine.

The tensile removing type internal fixing body is composed of a wedge separating vinyl tape 10a for facilitating separation of the wedge assembly 10 between the wedge assembly 10 and the internal fixing body 5 as shown in Fig. Respectively.

However, since the vinyl tape 10a according to the related art as described above can not be fixed in position precisely on the wedge assembly 10, the vinyl tape 10a can not be installed when the wedge assembly 10 and the inner fixing body 5 are coupled. Is wrinkled or folded, the wedge separation can not be performed.

In addition, if the vinyl tape 10a is not fixed in the correct position in the process of engaging the wedge assembly 10 and the inner fixing body 5, the vinyl tape 10a may be attached to the wedge assembly 10 and the inner fixing body 5 of the wedge as a pinching member.

3, a screw cap 60 is placed on the tip of the main body 50 of the inner fixing body B, and the wedge- Thereby protecting the components contained in the main body 50 including the assembly.

The inner fixing body B includes a main body 50, a screw cap 60, a wedge assembly 70, a wedge expansion ring 81, a tension member film 83, a safety ring support 85, A ring 87, and a wedge lock ring 89. As shown in Fig.

The main body 50 has a tubular shape and the rear end portion of the inner circumferential surface is a wedge leftward tapered portion 51 by tangential posture and a rear end portion of the main body 50 behind the wedge left portion 51 is covered with a flexible synthetic resin tube A tube groove (52) is also formed in which the tip of the tube is fitted when the tip of the tensile material is inserted.

A margin portion 53 is formed in front of the wedge seat 51 near the given wall to secure a space in which the wedge assembly 70 can retreat. A screw 54 for fastening the wedge lock ring 89 and a ring tuck 55 which seats the wedge lock ring 89 at the tip of the clearance 53.

The wedge assembly 70 includes a plurality of wedges 71 arranged in the circumferential direction. 4, a ring horn 71a for fitting a wedge safety ring 87 is formed on the distal end face of the wedge 71, and an outer peripheral front end portion 71b of the wedge 71 is engaged with the wedge left 51 (See FIG. 2).

The rear half of the wedge 71 is a tapered surface 71c corresponding to the wedge seat 51. [ The tapered surface 71c acts to strongly attract the tensile material as the wedges 71 are attracted to the rear end of the wedge seat 51 while being pressed against the tip of the tensile material by the force when the tensile material is tensioned.

A semicircular locking ring groove 71d is formed in the circumferential direction about the middle of the outer surface of the tip portion 71b. The locking ring groove 71d maintains the assembled state of the wedge assembly 70 by inserting the wedge lock ring 89 and when the external fixation of the tensile material is released, the wedge assembly 70 retracted by the reaction force removes the tensile material The wedge assembly 70 has a shallow groove shape in which the edge is processed with a gentle curved line so that the wedge assembly 70 can easily escape from the wedge lock ring 89 that locks the wedge assembly 70 to prevent the wedge assembly 70 from coming out.

A wedge locking groove 71e is formed at the boundary between the front end portion 71b and the rear portion 71c of the wedge 71, that is, behind the locking ring groove 71d. The wedge lock groove 71e is locked to the wedge lock ring 89 when the wedge assembly 70 is pulled back by the force that the tensile member is tucked toward the tip of the inner fusing member by the reaction force when the external fixation of the tensile material is released, At the moment the groove 71e coincides, the wedge assembly 70 is locked by the locking ring 89, which is elastically released, so that the wedge assembly 70, which was retracted when the wedge- .

On the inner surface of the wedge 71, a groove 71f is formed at a position before the lock ring groove 71d. The membrane groove 71f is a reaction force relay means for transmitting the reaction force of the tensile material to the wedge assembly 70 when the tip of the tensile material hitting the wedge assembly 70 comes into contact with the wedge assembly 70 and releases the external fixation, And a tension member curtain 83 serving as a stopper for restricting the insertion length of the tension member 83 when it is held.

Further, on the inner surface of the wedge 71, a membrane 71g is formed at the back of the groove 71f. The opening ring groove 71g is where the wedge opening ring 81 for opening the wedges 71 is inserted. The opening ring groove 71g is placed behind the lock groove 71e. This is necessary to allow the wedges 71 to be easily widened by the wedge ring 81 when the wedge assembly 70 is retracted within the body 50 to facilitate wedge engagement with the leading edge of the tensile material.

4 again, the screw cap 60 is fastened to the screw 54 provided at the tip of the main body 50 to protect all the interior parts of the main body 50, while the internal fixture is fixed and tension is applied to the tensile material The wedge safety ring 87 is held together with the main body 50 so that the wedge safety ring 87 is held at the center of the front end face of the main body 50, The screw 62 is formed.

The inner edge of the rear end of the screw cap 60 is an outwardly tapered beveled surface 63. This beveled surface 63 is formed by provisional fixation of the front edge of the wedge safety ring 87 and provisional fixation of the tension member to the wedge safety ring 87 when the tensile material is tensioned in the inner fixture, Is necessary to allow the wedge safety ring 87 to escape easily between the screw cap 60 and the safety ring support 85 while being elastically disengaged.

The wedge safety ring 87 is inserted into the ring horn 71a as the wedge assembly 70 and placed on the front surface of the wedge lock ring 89 seated on the ring tilts 55 of the main body 50, And the internal surface of the screw cap 60 and the internal surface of the screw cap 60. After the internal fixture is inserted and fixed in the anchor hole of the fixture, external factors such as the fluctuation of the tensile material and the internal fixture, And is a C-shaped elastic ring that is temporarily locked so that the wedge engagement state of the tensile material by the edge wedge assembly 70 is maintained.

The wedge lock ring 89 holds the plurality of wedges 71 in a circumferential direction to maintain the shape of the wedge assembly 70 and to retract the wedge assembly 70 when the external fixation of the tensile material is released, The locking groove 71e of the locking claw 71e is engaged with the locking groove 71e to lock the wedge assembly 70 in place by locking it in place.

The wedge opening ring 81 is formed by wedging the wedges 71 in an outwardly elastic manner as opposed to the wedge locking ring 89 which collects a plurality of circumferentially divided wedges 71 together and maintains the combined state of the wedge- This is also a C-shaped elastic ring.

The tensile material film 83 transfers the reaction force of the moment when the film is inserted into the groove 71f and the external fixation of the tensile material is released to the wedge assembly 70 to retract so that the leading end of the tensile material is transferred to the wedge assembly 70 And is a circular metal plate having a radius and strength such that the film does not leave the grooves 71e after being set in the main body 50 and fixed.

The safety ring support 85 is supported on the wedge lock ring 89 fitted to the wedge assembly 70 by the back edge of the wedge safety ring 87 and supported by the beveled surface 63 of the screw cap 60 The wedge safety ring 87 is a metal ring, which supports the wedge safety ring 87 so that it is properly held.
