Description

Structure of self-adjusting angle anchor bracket for eath anchor method}

The present invention relates to an earth anchor method used during earth retaining construction, and more particularly, to an automatically adjustable anchor bracket.

When excavating the basement during construction and civil works, earth retaining work is performed to prevent the collapse of the surroundings of the building due to the pressure of the soil.

The earth anchor method is a method of drilling a hole in a retaining wall instead of a brace with an earth drill, inserting a tension member such as reinforcing bar or PC rigidity (wire) into the hole, grouting the area around it with mortar to harden it, and then applying tensile force to PC steel wire or reinforcing bar from the outside to fix it. It has good work efficiency, and since the anchor body is an individual structure, it is a construction method mainly adopted in most construction and civil engineering works due to its good applicability.

To briefly introduce the earth anchor method, earthen retaining walls are made by constructing earth plates between thumb piles, then drilled on earth plates using a crawler drill and compressor, then mounted casing, and when drilling is finished, separate casing, insert earth anchor wire after drilling is completed, inject cement milk into the earth anchor insert injection pipe, cure it, grout the earth anchor hole, install wales on the top and bottom, and installed wales Anchor brackets (pedestals), which are tension supports for steel wires (wires), are installed on the upper and lower parts, and then the ground anchor steel wires (wires) are adjusted and installed according to the design load (specifications) using a tensioner.

The present invention consists of a body member 100, a rotation block member 70, and a fixing member 80.

The body member 100 is composed of a pair of side plate members 10 having the same structure, and the side plate member 10 is structurally formed in a triangular shape by combining an upper inclined portion 10-1 and a lower inclined portion 10-2.

In addition, a deformation prevention hole 16 is provided between the upper inclined portion 10-1 and the lower inclined portion 10-2, and the deformation preventing hole 16 extends horizontally at the same position as the lower inclined portion 10-2. It is formed. Therefore, it is formed to minimize distortion such as deformation by distributing the pressure received by the lower inclined portion 10-2.

The upper inclined portion 10-1 is formed by protruding the upper contact portion 12 to the rear surface, so that the upper reinforcing portion 20 can be interviewed.

The lower inclined portion 10-2 is formed by protruding the lower surface portion 13 to the rear surface, so that the rear surface reinforcement portion 60 is interviewed, and the upper portion of the lower surface surface portion 13 has a protruding portion 14. It is formed so that it can be mounted on the upper surface 210 of the H beam during use.

A space portion 15 is formed between the upper contact portion 12 and the lower face contact portion 13, so that in one implementation, the upper face contact portion 12 is interviewed to the H-beam front portion 220, and the lower face contact portion 13 is interviewed to the H-beam front portion 220'. That is, the space part 15 is made of a structure that is not interviewed by the H beam during installation, and serves to distribute the load to the upper contact part 12 and the lower contact part 13 during use.

In order to prevent bending, the side plate member 10 has a front reinforcement part 30 on one side of the upper part of the upper inclined part 10-1 and an extension part 40-1 on the lower part of the upper inclined part 10-1, and the central reinforcement part 40 and the lower reinforcement part 50 are formed sequentially on the upper part of the lower inclined part 10-2,

The extension part 40-1 and the central reinforcing part 40 should be integrally formed.

A through hole 11 is formed in the center of the side plate member 10 so that the rotary block member 70 and the fixing member 80 can be interviewed.

A roller interview portion 11-1 is formed in a semicircular shape inside the through hole 11 to interview the rotating roller 70-6 of the roller portion 71, and in order to distribute the load of the roller interview portion 11-1, the roller interview portion 11-1 has a horizontal reinforcement part 11-2 at the top, a triangular reinforcement part 11-3 at the center, and an inclined reinforcement part 11-4 at the bottom. can be distributed.

The diameter or width of the roller face portion 11-1 should be greater than that of the rotating roller 70-6 of the roller portion 71 for a correct structure. In addition, the circular arc of the roller interview unit 11-1 should not exceed a maximum of 180°, and this is because the roller unit 71 can be mounted toward the front side.

The rotating block member 70 is divided into a horizontal plate 70-1 and a roller unit 71.

The horizontal plate 70-1 is formed by penetrating the anchor head inner part 70-2 so that the anchor head 200 can be placed in the center.

A triangular support plate 70-3 is formed below the horizontal plate 70-1, and a rotation roller 70-6 having a second screw part 70-5 formed in the center near the vertex of the support plate 70-3 is provided. In addition, an inner reinforcing part 70-4 is separately provided on the rear surface of the support plate 70-3 and the rear surface of the rotation roller 70-6 to minimize damage to the rotation roller 70-6 due to the load of the support plate 70-3.

The rotational roller 70-6 of the roller unit 71 is mounted on the roller facet 11-1 of the side plate member 10 and then fixed to the fixing member 80 to enable rotation. That is, after the rotating roller 70-6 is mounted on the roller face portion 11-1, the first screw portion 80-3 of the fixing member 80 is screwed into the second screw portion 70-5 of the rotating roller 70-6 by the through hole 11 to be fixed. The first screw portion 80-3) and the second screw portion 70-5 have a structure in which a female screw and a male screw are connected in a screw coupling method.

The fixing member 80 is formed of two circular arcs.

The fixing member 80 has a circular portion 80-1 formed in a cylindrical shape, and a semicircular portion 80-2 having a semicircular shape is provided on the outer diameter of the circular portion 80-1. That is, since the semi-circular portion 80-2 has the same diameter and diameter as the rotating roller 70-6, it can prevent the rotating roller 70-6 from coming off to the front, and since the circular portion 80-1 does not adhere to the through hole 11, the load is not transmitted to the fixing screw when the anchor head is installed. Accordingly, deformation and damage of the fixing member 80 are minimized, and separation and maintenance are simplified due to the small-diameter circular portion 80-1. can be done smoothly.

In addition, as shown in the attached FIG. 8, the angle display member 110 protrudes and is formed on the front surface of the upper inclined portion 10-1 so that the rotation angle of the anchor head 200 can be confirmed.
