Description

Removable Ground Anchorage}

The present invention relates to anchors used in construction or civil engineering construction, and more particularly, to a dismantleable temporary ground anchor body which can be easily dismantled by improving the constructability.

Permanent ground anchors are anchors that are installed to prevent the movement or distortion of the construction when constructing buildings such as groundwater leaching grounds, slopes, earthquakes, etc., and as a basement fixing structure to be removed after completion of construction, there is a temporary ground anchor bar, the present invention Relate to hypothetical ground anchors.

When constructing high-rise buildings, underground structures of subways or other large structures As the depth of the underground is added, the H beam is fixed vertically to the periphery and a large wall is used to form the earth wall or the exponential wall. In this case, the earth pressure around the transverse transverse flow installed is subjected to pressure of several hundred tons as it enters the basement, resulting in an accident in which the earth wall collapses without overcoming the pressure.

In order to prevent the collapse of the earth wall, a forced ground hole connecting both earth walls in the underground space excavated using a large beam is sometimes installed.

However, these forced support structures cause various problems such as deterioration of work efficiency, extension of construction period, and increase of construction cost due to the structure installed by the grid.

Accordingly, the present invention has been made to solve the above problems, and the object of the present invention is to provide a disassembleable temporary ground anchor body that can be easily and quickly separate the steel wires used in the anchor body to improve the constructability. have.

The present invention for achieving the above object, and a cylinder body having a receiving groove in which a plurality of spacers and tension rebound cone is fitted; An upper disk fixed via a cylinder body to press and support the tension rebound cone; A pair of brackets fixed to the upper disk; A lower disk having the same number of through-holes as the tension member to fix the tension lower portion fitted in the binding state through the spacer and the tension material binding cones; It is provided with a cap which covers the upper part of the said cylinder body.

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

1 is a schematic cross-sectional view of the installation state of the anchor according to the present invention, the present invention is an anchor hole (2) is formed so as to have a predetermined slope on the ground (1), as shown in the figure, the spacing in the anchor hole (2) An anchor is installed in a state in which tension tension member (A) and dismantle tension member (B) are maintained at predetermined intervals through the ash (3), and mortar in which cement and water are combined is injected around the assembly. A well-known earth wall 6 is constructed at the inlet of the anchor hole 2, and a strip 7 is provided at the earth wall 6.

In addition, the anchor 10 has a cylinder body 15 having a receiving groove 14 into which the plurality of spacers 11 and the binding cones 12 and 13 are fitted in the vertical direction as shown in FIGS. 2 and 3, respectively. Wow; An upper disk 16 fixed to the cylinder body 15 to press and support the binding cone 13; The same number of through-holes as the tension member to fix the lower tension tension member (A) and the dismantle tension member (B) to be fitted in a state in which the spacer 11 and the binding cones (12, 13) are bound. A lower disk 18 formed thereon; A cap 19 is provided on the upper portion of the cylinder body 15.

The upper disc 16 has a central through hole 20 formed at a central portion thereof, and a plurality of outer through holes 21 formed radially around the central through hole 20. ) Has a diameter enough to allow the binding cone 12 to pass through.

In addition, a hollow support rod 22 is placed on the binding cone 12 and the support rod A pair of brackets 23 supporting the 22 are attached, and the brackets 23 are provided with a fastening portion 24 on one side and in one direction on the other side facing the fastening portion 24. A bent flange 25 is formed, while a through hole 27 is formed in the flange 25 so that the intermediate element 26 constituting the dismantling tension material B can pass therethrough. .

On the other hand, the binding cones (12, 13) using a conventional wedge cone and forming a conical shape as a whole, the tapered surface 28 is formed on one side, these tapered surfaces 28 are in surface contact with the spacer 11 The spacer 11 is provided with a tapered surface 29 corresponding to the tapered surface 28, while being fitted into the furnace accommodation groove 14, so that the cohesion forces between the binding cones 12 and 13 and the spacer 11 are mutually close. As a result, tension tensioning material A and dismantling tensioning material B are firmly bound on the cylinder body 15.

Therefore, when the external force is removed from the dismantling tension member (B), the tension member (B) leads the binding cones (11, 12) and protrudes in the direction of the arrow, and at the same time, the spacer (10) supporting the binding cones (11, 12). ) As the force balance state collapses as the force is displaced toward the center in the direction of dismantling tension material (B), the binding state of the tension tension material (A) is also released. 12 are gathered into the cap 18 through the central through hole 19 formed in the upper disk 15.

Figure 6 shows an anchor 50 according to a second embodiment of the present invention, which is configured to be used for all the tension material.

That is, the cylinder body 52 in which the receiving groove 51 is formed in the vertical direction, and the receiving groove 51 Spring 53 and a plurality of binding cones 54, which are installed in the tension tension material (A) for holding the binding state via the binding cone 54, the upper and lower portions of the tension tension material (A), respectively, The upper disk 55 and the lower disk 56 to be interposed between the upper disk 55 and the tension member space-separating material 57 is provided to provide a space for the tension tension material (A) elastic operation, and the The cap 58 is provided on the cylinder body 52.

In addition, unlike the anchor body according to the first embodiment, the anchor body according to the second embodiment is configured such that the binding cones 54 bind the tension members only with mutual support force between the binding cones without a spacer.

Therefore, when the external force is removed from the tension member, the tension tension member A leads the binding cones 54 to protrude in the direction of the arrow, wherein the compressed spring 53 moves in the opposite direction to the direction of travel of the tension members A and B. Since the binding cones 54 are pushed out to regulate the binding cones 54 to reenter into the receiving groove 51, the elasticity of the tension members (A, B) is maintained, which is tension tension member (A). And when dismantling the tensioning material (B) is shown at the same time.

On the other hand, the anchor body according to the present invention is not limited to the above-described embodiment and can be carried out by changing the structure according to the place of use, the second bracket 23 used for the anchor body 10 of the first embodiment It can be applied to the anchor body 50 according to the embodiment.

As described above, according to the present invention, It is to improve the workability by allowing the easy anchor to be dismantled after the completion of construction.
