The connection tube 120 is inserted into and fixed so that the strand (S) can be fixed by the wedge 130 after penetrating.

In addition, the frame 111 and the wedge insertion portion 112 are connected by a plurality of ribs 114 to reinforce the overall connection strength.

In the core post-treatment method using general post-tensioning method, since there is no separate configuration for inserting and fixing the stranded wire to the pre-constructed core member, a buried anchor fixed to one side of the stranded wire is placed close to the outside of the core member. After installing the tensioned end fixed to the other side of the strand, the slab is constructed by placing the slab concrete (see Fig. 1).

However, this method cannot support the sub-moments generated at the connecting portion of the core and the slab because the strand does not extend sufficiently to the central region of the core member. There is a problem that must be reinforcement during construction.

The buried anchor 110 of the present embodiment is disposed so as to be buried in the central region of the core member (C) bar can be omitted this reinforcement and thus has the advantage that can facilitate the construction.

The wedge 130 is configured to be inserted and fixed to one side of the buried anchor 110 so as to fix the strand S disposed through the buried anchor 110.

As shown in FIG. 3, the wedge 130 is divided into three cones 131, 132, and 133 formed on the inner circumferential surface of a plurality of teeth 131a, 132a, and 133a, and are spaced apart from each other before insertion of the strand S. While being kept in a closed state, the insertion of the strand (S) is inserted into the insertion hole (110a) of the buried anchor (110) so that it can be firmly fixed to the strand (S).

Of course, according to another embodiment of the present invention, the wedge 130 may be divided into two cones or four or more cones (not shown).

The closing cap 140 is prepared in a state in which grease (G) is pre-filled in the anchor coupling portion 141 and the spacer receiving portion 143, respectively, and is coupled to the buried anchor 110. When the spacer 150 moves toward the spacer receiving portion 143 according to the use of the unit 100, grease G naturally flows into the buried anchor 110 to efficiently prevent permanent corrosion of one end of the inserted strand S. It becomes possible to prevent it.

The spacer 150 spaces the cones 131, 132, and 133 constituting the wedge 130 before insertion of the strand S. When the insertion of the strand S is completed, the spacer accommodating groove of the closing cap 140 is formed. The cones 131, 132, and 133 of the wedge 130 are moved in close contact with each other so as to be able to fix the strand S.

The spacer 150 has a circumferential shape, but the size of the spacer 150 is slightly smaller than the spacer receiving groove 143a so as to pass through the inside of the pressure spring 160. Of course, according to another embodiment of the present invention, the shape of the spacer 150 may be changed as much as the scope of the present invention is not limited by the shape of the spacer 150.

As described above, the size of the spacer 150 is limited to allow the spacer 150 to be moved toward the spacer receiving portion 143 of the closing cap 140 according to the insertion of the strand S. The method of use of the invention will be described in detail.

Meanwhile, the pressure spring 160 is interposed between the wedge 130 and the closing cap 140 to press the wedge 130 to the buried anchor 110.

The sacrificial tube 170 is connected to the buried anchor 110 at the time of construction of the core member C to provide a passage for inserting the strand S into the buried anchor 110 after completion of the construction of the core member C. It is a structure extended to the formwork M side.

The sacrificial tube 170 of the present embodiment is provided as a hollow cylindrical member made of a plastic material having flexibility, one end is coupled to the connection pipe 120 coupled to the buried anchor 110, the other end to the construction of the core member (C) After protruding to the outside of the formwork (M) is fixed by the sacrificial tube fixing portion 190 to be described later.

If necessary, the sacrificial pipe 170 may be omitted, but when the concrete poured to construct the core member C is cured together with the anti-deformation rod 180 described later, the anti-deformation rod 180 is removed and the strand S Since it becomes difficult to insert the bar, the use of the sacrificial tube 170 is determined in advance in consideration of the overall length of the deformation preventing rod 180 corresponding to the thickness of the core member (C).

The deformation preventing rod 180 prevents the sacrificial pipe 170 from being deformed when concrete is laid for the core member C and is easily separated from the sacrificial pipe 170 after completion of the construction of the core member C. As a result, the bar shape is configured to penetrate the sacrificial tube 170 so as to provide a space into which the strand S may be inserted.

The deformation preventing rod 180 includes a rod body 181 provided to have a diameter larger than the diameter of the strand S, and a wedge inserting portion 183 provided to have a diameter smaller than the diameter of the rod body 181. .

The rod body 181 has a bar shape formed of a plastic material, and the diameter of the rod body 181 is greater than that of the strand S, thereby removing the strain preventing rod 180 and inserting the strand S. This can be done smoothly.

As shown in FIG. 2, the wedge insertion part 183 is a conical configuration provided to gradually decrease in diameter from one end of the rod body 181.

The wedge insertion part 183 is provided to have a diameter smaller than the rod body 181 in order to easily insert the deformation preventing rod 180 into the above-described buried anchor 110, buried anchor 110 and the deformation preventing rod 180 ) Make sure that the coupling is smooth.

The deformation preventing rod 180 is easily inserted into the buried anchor 110 through a wedge inserting portion 183 formed in a conical shape at one end thereof, thereby being closely adhered to the inside of the buried anchor 110, and the other end thereof is fixed to the sacrificial tube. It is fixed to one side of the formwork (M) by the government (190) to prevent the flow of the sacrificial pipe (170) during the pouring of concrete for the construction of the core member (C).

As described above, according to another embodiment of the present invention, the sacrificial tube 170 may be omitted. In this case, the core member C is constructed in a state in which the deformation preventing rod 180 is directly inserted into the buried anchor 110. When the deformation preventing rod 180 is removed later, a passage through which the strand S can be inserted into the buried anchor 110 is provided.

On the other hand, the sacrificial tube fixing portion 190 is configured to be fixed to the sacrificial tube 170 and the deformation preventing rod 180 extending from the buried anchor 110 to one side of the form (M).

As shown in FIG. 4, the sacrificial tube fixing part 190 may include a first unit fixing part 191 and a second unit fixing part 193 and a first unit fixing part provided to have symmetrical shapes. 191 and a fixing band 195 which integrally binds the second unit fixing part 193.

Sacrificial tube insertion grooves 191a and 193a are formed in the first unit fixing part 191 and the second unit fixing part 193 facing the buried anchor 110 to respectively insert and fix one end of the sacrificial tube 170. The outer circumferential surface is formed with band insertion grooves 191b and 193b for inserting and fastening the fixed band 195, respectively, and a milk discharge groove 192a for naturally discharging the concrete milk at the lower side thereof.

According to this configuration, the first unit fixing part 191 and the second unit fixing part 193 are sandwiched at both ends of the sacrificial tube 170 and the deformation preventing rod 180 protruding to the outside of the formwork M, respectively. When the sacrificial tube 170 is inserted into the sacrificial tube insertion groove (191a, 193a), the deformation preventing rod 180 penetrates the first unit fixing portion 191 and the second unit fixing portion 193 to the outside It becomes a protruding state.

Next, when the fixing band 195 is unwound and wrapped around the band insertion grooves 191b and 193b and the bolt B is rotated, the fixing band 195 is gradually reduced while the first unit fixing part 191 and the second unit high. The government (193) will be united.

In addition, even when the first unit fixing part 191 and the second unit fixing part 193 are completely bound by the fixing band 195, the first unit fixing part 191 and the second unit fixing part 193 The milk discharge groove 192a having a predetermined size is formed at the lower side, and the milk flowing into the sacrificial pipe 170 side of the concrete milk poured for construction of the core member C is naturally discharged through the milk discharge groove 192a. It becomes possible.

The milk discharge groove 192a effectively prevents the milk from hardening together with the sacrificial tube fixing part 190 by naturally discharging the concrete milk so that the sacrificial tube fixing part 190 is completed after the completion of the construction of the core member C. It will help to separate smoothly from the 170 and the anti-deformation rod 180.

In addition, although not described, nail holes 192b for penetrating the first unit fixing unit 191 and the second unit fixing unit 193 to the mold M, respectively, are formed through.
