Abstract

PURPOSE: An earth anchor bracket is provided to be stably supported by connecting a bearing plate to a hanging groove of an inclined side plate although horizontal component force or torsional force is applied. CONSTITUTION: An earth anchor bracket comprises a pair of inclined side plates (12) and a support plate (17) mutually connecting the inclined side plates. A hanging groove (14), which a whole bearing plate (15) is inserted in and connected to, is formed on the inclined outer side surface of the inclined side plate. The bearing plate is welded on the inclined side plate while being inserted into the hanging groove.

Description

Earth ancher bracket {Earth ancher bracket}

The present invention relates to an earth anchor bracket, and more particularly, to a ground anchor bracket of a new structure that can be firmly mounted to the pressure plate of the anchor body.

In general, when digging or foundation work is carried out at a civil construction site, H beams are embedded in the ground, and supporting plates are inserted between the H beams to form earth walls, and horizontal beams called bands are placed on the outside of the earth walls. The earth anchor method which uses the air anchor bracket, embeds an earth anchor in the ground, and supports the earth wall, so that the side wall of the excavated soil may not fall, is widely used.

Figure 1 shows the structure of the conventional anchor anchor bracket, which is installed on the horizontal beam (3) of the outer surface of the earth wall (1), the earth anchor bracket (1), through the earth wall (1) A base end portion of the anchor body 6 fixed to (2), comprising a pair of inclined side plates 12 spaced apart from each other and a supporting plate 17 for interconnecting the inclined side plates 12, The pressure plate 15, on which the through hole 16 through which the anchor body 6 is coupled, is welded and fixed to the inclined outer surface of 12).

In the conventional earth anchor bracket, a large tensile force acts on the anchor body 6 to resist a large earth pressure acting on the earth wall, and thus is perpendicular to the acupressure plate 15 supporting the tip of the anchor body 6. Large loads act in the direction. In addition, when the actual installation angle of the anchor body 6 and the angle of the pressure plate 15 deviate from the right angle according to the construction error or the site conditions, the side plate of the pressure plate 15 is lateral by the lateral component acting on the anchor body 6. The load in the direction, that is, the load along the inclined surface of the side plate 12 also acts greatly. As a result, the pressure plate 15 may be bent or deformed. As described above, when the pressure plate 15 is twisted, the pressure plate 15 attached to the inclined side plate 12 is separated from the inclined side plate 12, so that the structure of the earth anchor bracket is weak.

Meanwhile, an earth anchor bracket having a toothed portion or an uneven portion formed on the inclined side plate 12 and having the pressure plate 15 configured to be adjustable on the inclined side plate 12 has been introduced, but the position adjustable earth anchor bracket has a structure. Due to the complexity, the production is cumbersome and not easy to be installed in the field, and it is deformed or rusted due to repeated use, so the reuse rate is low in the field, and the pressure plate 15 is deformed as a large load is applied to the pressure plate 15. There was a problem in that it is separated from the inclined side plate 12 structurally weak.

Patent Registration No. 10-0760213

The present invention has been proposed in view of the problems of the conventional earth anchor bracket as described above, the present invention has a simple structure, easy to manufacture and construction, high reuse rate, even if a large force acting on the anchor anchor bracket the pressure plate It is an object of the present invention to provide a new structure of the anchor anchor bracket which can firmly support the anchor body by maintaining the fixed position without departing from the inclined side plate.

According to one feature of the invention, it is installed on the horizontal beam (3) of the outer surface of the earth wall (1), and secures the proximal end of the anchor body (6) which is fixed to the ground (2) through the earth wall (1), A pair of spaced-side inclined side plates 12 and a support plate 17 interconnecting the inclined side plates 12, and through which the anchor body 6 penetrates the inclined outer surface of the shanghai inclined side plate 12; In the earth anchor bracket to which the acupressure plate 15 on which the ball 16 is formed is coupled, the inclined outer surface of the inclined side plate 12 is provided with a locking groove 14 into which the entire acupressure plate 15 is inserted and coupled. The acupressure plate 15 is provided with an earth anchor bracket, which is welded to the inclined side plate 12 while being inserted into the locking groove 14.

According to the present invention, a locking groove 14 is formed on the inclined side plate 12 of the earth anchor bracket to insert and couple the entire pressure plate 15, and the pressure plate 15 is inserted into the locking groove 14. The welding plate is welded to the furnace inclined side plate 12, so that even if a strong load acts on the pressure plate 15 due to the tensile force of the anchor body 6 or a horizontal component force or torsional force acts due to construction errors, the pressure plate 15 inclines. Since it is coupled to the engaging groove 14 of the side plate 12 and is not easily separated, the pressure plate 15 of the earth anchor bracket can maintain the position to firmly support the anchor 6. In addition, according to the present invention, the structure of the earth anchor bracket is simple and easy to manufacture and construction, even if repeated use it can prevent the reuse rate is lowered in deformation or corrosion of parts.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. 2 is an exploded perspective view of an embodiment of the present invention, Figure 3 is a construction state diagram of the embodiment.

As shown, the anchor anchor bracket of the present invention is installed on the horizontal beam 4 disposed on the outside of the earth wall 1, the anchor body which is embedded in the ground 2 and grouted and fixed through the earth wall 1 ( 6) and a pair of inclined side plates 12 vertically installed on the horizontal beams 3 and a through hole 16 which is supported by being placed on the inclined side plates 12 and through which the tip of the anchor body 6 passes. The formed pressure plate 15 is included. The inclined surface 13 of the inclined side plate 12 is manufactured at an appropriate angle so as to support the anchor body 6 at right angles corresponding to the design angle of the anchor body 6 embedded in the ground.

On the inclined side plate 12, a stiffening groove 13 into which the whole pressure plate 15 is inserted and coupled is formed. And the pressure plate 15 is fitted into the coupling groove 13 is coupled. In addition, the pressure plate 15 is welded in the state fitted in the coupling groove 13 is joined to the inclined side plate 12.

According to this configuration, since the pressure plate 15 is welded to the inclined side plate 12 in a state of being fitted into the engaging groove 14 formed on the inclined surface 13 of the inclined side plate 12, it acts in the vertical direction on the pressure plate 15. Even if the load acts along the horizontal component force, that is, the inclined surface 13, depending on the tensile force of the anchor body 6, as well as the torsional force according to the construction error or site conditions, the acupressure plate 15 is locked. ), The anchor body 6 can be firmly supported. In addition, since the structure for supporting the pressure plate 15 to the inclined side plate 12 is simple and simple, the number of parts of the earth anchor bracket is reduced and the structure is simple, so that the construction is easy and the construction in the field is easy, and the breakage or deformation of parts Alternatively, the reuse rate of the earth anchor bracket due to corrosion is prevented from being lowered.
