Description

Bracket device for earth anchor {BRAKECT DEVICE FOR EARTH ANCHOR}

The present invention relates to a bracket device for an earth anchor, and relates to a bracket for fixing an anchor body during the construction process of an earth anchor.

In general, the earth anchor method is widely used as a way to prevent earth walls from collapsing due to ground earth pressure acting as earth walls when excavation holes are formed during earth digging (burrowing) work in civil construction work or foundation work. In the anchoring method, a bracket is required to apply tensile force to the strands of the anchor body and fix them.

That is, in the earth anchor method, a wale (horizontal beam) made of H beams is installed on the earth wall formed by an excavation hole, then a drilling hole is formed in the earth wall, a bracket is installed on the wale, and the anchor strand is inserted into the wale.

Then, as the anchor body is fixed by tensioning the strand by grouting, a portion of the strand is exposed to a certain length from the bracket, thereby maintaining the uprightness of the earth wall and resisting earth pressure.

As such, the earth anchor bracket is fixed to the horizontal beam by welding or the like because it has to withstand the tension of the strand and the high load on the earth wall, so high compressive pressure performance and rigidity are required.

Therefore, according to the conventional earth anchor bracket, when the bracket is installed on the horizontal beam, work by skilled workers (installation, welding, etc.) is performed, which increases cost and construction period, and it is difficult to dismantle the bracket, making it impossible to recycle. there was.

On the other hand, when trying to dismantle the bracket after the completion of the structure construction, a work process in which oxygen welding or cutting of the welded part is added, which increases the construction period and exposes the worker to a dangerous situation, so there is a problem in securing safety.

In addition, the bracket protrudes from the outside of the horizontal beam, that is, into the construction space of the structure where formwork and scaffolding can be installed, and the construction space is very narrow, resulting in poor workability. There was a problem.

In addition, a part of the wale 10 is inserted into the couplers 20a and 20b and mutually supported to fix the bracket 20 to the wale 10 more firmly.

For example, in the couplers 20a and 20b, the first horizontal beam 12 is inserted into the first coupler 20a by the rotation of the bracket 20, and the second horizontal beam 12 is inserted into the second coupler 20b ( 14) can be fixed so as to firmly support the first and second horizontal beams 12 and 14 and the bracket 20 with each other as they are inserted.

Referring to Figures 5a and 5b to explain the operating method of the bracket installed on the wale according to the present invention, the earth wall is installed to prevent collapse of the soft ground when a steep slope is formed in excavation or foundation work at a civil engineering and construction site. do.

In the front, which is the construction space of the earth wall, vertical beams are installed at regular intervals in the vertical (longitudinal) direction from the ground, and the first horizontal beam 12 with wale 10 in the horizontal (lateral) direction on the vertical beam toward the construction space The second horizontal beams 14 are installed sequentially along the longitudinal direction of the vertical beams at regular intervals.

It is excavated at a predetermined inclination angle between the first horizontal beam 12 and the second horizontal beam 14 to form a perforation so that the anchor body can be inserted.

The bracket 20 is inserted between the first horizontal beam 12 and the second horizontal beam 14 in parallel with the wale 10, and the fixing member 30 is aligned with the perforated part around the axis and then inserted.

Thereafter, the bracket 20 is rotated so as to be perpendicular to the wale 10, but the lifting hole 223 is positioned so as to face the first horizontal beam 12. At this time, the outer and inner surfaces of the front flange of the first horizontal beam 12 are fixed in close contact with one side of the first plate 22 and the second plates 241 and 242, respectively, and the second horizontal beam 14 The outer and inner surfaces of the front flange are adhered and fixed by the other sides of the first plate 22 and the second plates 241 and 242, respectively, so that the bracket 20 is firmly attached to the first and second horizontal beams 12 and 14. can be fixed

As described above, the fixing member 30 of the bracket 20 and the perforation part are aligned around the axis, and the anchor body EA passes through the fixing member 30 and is inserted into the perforation part, followed by grouting.

At this time, the bracket 20 is firmly supported by the first horizontal beam 12 and the second horizontal beam 14 to support the anchor body. The support capacity of the bracket 20 against various external forces is further improved.

Through this, the first horizontal beam 12, the second horizontal beam 14, and the fixing member 30 evenly distribute the support pressure for the tensile force of the anchor body to the first and second plates 22 and 24, The bracket 20 can sufficiently overcome the tensile force of the anchor body.

In addition, the first and second plates 22 and 24 are supported from the first horizontal beam 12 and the second horizontal beam 14 by the tensile force of the anchor body, so that they are not bent or twisted, and as a result, the tensile force of the anchor body is reduced. can perform well enough.

In addition, the bracket 20 can sufficiently support the tensile force of the anchor body even under a lightweight structure, thereby improving workability due to light weight and reducing manufacturing costs.

In addition, as shown in FIG. 6, the present invention suggests an example in which the upper and lower supports 243 and 244 are configured between the second plates 241 and 242. The support pressure for the tensile force applied to the anchor body is distributed to each of the second plates 24 through the first plate 22, and each of the second plates 24 moves integrally to the anchor body of the bracket 20. It is to double the bearing capacity against the tensile force.

In this embodiment, in addition to this, as shown in the drawing, a weight 245 is further configured in the support 244 formed at the bottom, which, as shown in FIG. ) and the second horizontal beam 14, and then rotate the bracket 20 as shown in FIG. 5B so that the bracket 20 is fixed to the wale 10, the constructor supports only the fixing member 30 In one state, rotation is performed by the weight of the weight 245 to promote ease of construction.

If there is no weight 245, the constructor has to artificially rotate one end of the bracket 20 while supporting the fixing member 30. Position adjustment is required. In this embodiment, if the installer supports only the fixing member 30, the rotation is made automatically to facilitate the construction.

Meanwhile, as mentioned above, the present invention makes the first plate 22 and the second plate 24 closely adhere to the wale 10, so that the bracket 20 can be attached to the wale 10 without welding or bolting. For mounting, of course, the length (height) of the second plate 24 must be smaller than the distance between the webs of the first horizontal beam 12 and the second horizontal beam 14. Accordingly, a gap is formed between the second plate 24 and the webs of the first horizontal beam 12 and the second horizontal beam 14 in a state where the bracket 20 is mounted on the wale 10. Due to this gap, twisting may occur in the bracket 20 when tensile force is applied to the anchor body, and this twisting may have a problem of not expressing sufficient bearing capacity and may cause defects such as bending in the bracket 20. .

Accordingly, in the present invention, as shown in FIG. 7, an example in which the elastic packing 246 is configured at the lower end of the second plates 241 and 242, and the pressing port 247 made of an elastic material is configured at the upper end. are presenting

In particular, the pressurizing part 247 is controlled by rotating and pressing the attachment end 247-1 attached to the outer side of the upper end of the second plate 24 and bent at the upper end of the attachment end 247-1. It is characterized in that it consists of a rotary pressing end 247-2 interposed between the upper end of the 2 plate 24 and the web of the upper wale (first horizontal beam 12).

When there is no external force, the pressing part 247 maintains the folded state of the attachment end 247-1 and the rotational pressure end 247-2, and then applies an external force so that the rotation pressure end 247-2 is attached to the attachment end 247-2. -1) is rotated as an axis, and as shown in FIG. 8B, it can be fitted between the second plate 24 and the web in a forced fit method.

As shown in the drawing, it is appropriate that the attachment end 247-1 is configured in a plate shape, and the rotational pressure end 247-2 is configured in a shape having a larger thickness than the attachment end 247-1.

The material of the packing 246 and the pressurizer 247 is not limited as long as it is made of an elastic material. For example, rubber or the like may be applied.

Looking at the operating state of this embodiment, as shown in FIG. 8A, when the bracket 20 is rotated between the first horizontal beam 12 and the second horizontal beam 14 to stand upright, the second plate 24 is moved by its own weight. The packing 246 configured at the lower end is in contact with the web of the second horizontal beam 14, and the upper end of the second plate 24 is in a state of forming a spaced apart from the web of the first horizontal beam 12. Subsequently, as shown in FIG. 8B, the rotational pressure stage 247-2 is interlocked with rotation and pressurized between the upper end of the second plate 24 and the web of the first horizontal beam 12 (247-2). ) is inserted so that the bracket 20 is firmly fixed in the wale 10. In this state, when a tensile force is applied to the anchor body, the support force is developed without twisting the bracket 20.

According to the earth anchor bracket device of the present invention, the process of installing and disassembling the bracket on the wale is convenient, and it is possible to work by unskilled people and reuse is possible, so cost can be reduced, and heavy equipment use or welding , cutting work, etc. are unnecessary in the process of installation and disassembly, so the safety of the operator can be secured, and the bracket installed on the wale has a buried structure that does not protrude into the construction space, so it is possible to secure the construction space and convenience of work. In addition, it has the effect of improving the quality of concrete construction.

Of course, the present invention is not limited to the above-described embodiments, and may include a combination of two or more embodiments or a combination of at least one embodiment and known technology as a new embodiment.
