FIG. 2 is a side view illustrating a ground rivet structure according to an embodiment of the present invention. FIG. FIG. 4 is a plan view illustrating a ground rivet structure according to an embodiment of the present invention. Referring to FIG. 1 to 4, the structure 1, the main anchor 10, the body 12, the tip 14, the incision 16, the head 18, the base plate 20, A main nut 30, a sub-anchor 40, a computer bolt 50, and a lining nut 52 are shown.

This embodiment relates to a ground rivet structure installed on the ground and in the ground to fix the ground mounting structure on the ground. Unlike the conventional method of simply tying an anchor on the ground, in the present embodiment, the base plate coupled to the front end of the main anchor is securely fixed to the ground with the sub-anchor, so that the main anchor is firmly fixed to the ground .

The ground rivet structure according to the present embodiment may be basically composed of a main anchor 10, a base plate 20, a main nut 30, and a sub anchor 40.

The main anchor 10 is a ground type component. A tip portion is connected to a distal end of the basic body 12 and a head portion 18 is connected to a distal end And may be formed in a connected shape.

As the main anchor 10, a steel pipe can be used. That is, the main body 12 of the main anchor 10 may be a cylindrical steel pipe. A rectangular pipe such as a square pipe may also be used as the main anchor 10. When the square pipe is used, the main anchor 10 buried in the ground is hard to rotate due to external force, so that the underground fixing force of the main anchor 10 can be improved.

The tip portion 14 serves to pierce the ground when the main anchor 10 is typed, and a horn-shaped member can be used. For example, when using the main pipe anchor 10, the conical tip 14 may be used. When the main pipe anchor 10 is used, a quadrangular pyramid tip 14 may be used.

The tip portion 14 may be joined to the distal end of the body 12 by welding or the like and may be fastened with a fitting or the like so that the tip can be physically separated later. When the tip portion 14 is separated and the distal end portion of the main anchor 10 is widened after the main anchor 10 is inserted, the tip portion 14 is coupled to the distal end of the body 12 in a detachable manner good.

The head portion 18 may be formed by a separate member that is a part to be hammered by a hammer or the like when the main anchor 10 is put on the ground and welded to the tip of the body 12 to connect the head portion 18, It is also possible to form the head portion 18 by molding the tip portion of the head portion 12.

A screw can be formed on the outer circumferential surface of the head portion 18 so that the main nut 30 can be fastened to the head portion 18 after seating the base plate 20 with the main anchor 10 as described later have.

In the case where the head portion 18 is formed as a separate member and then welded to the tip of the body 12, a metal bolt coating film may be used as the head portion 18 or a steel pipe pipe coating film formed on the outer surface thereof have. Alternatively, when the steel pipe is used as the main anchor 10, the head portion 18 can be formed by directly machining a screw shape at the tip portion of the body 12.

The head portion 18 according to the present embodiment is not only a portion for hitting with a hammer or the like but also a portion exposed to the ground when the tip portion 14 and the body 12 are inserted into the ground by using the main anchor 10 . That is, all or a part of the head portion 18 is exposed on the ground, so that the main nut 30 described later can be fastened.

The base plate 20 is a component that is attached to the ground surface of the main anchor 10. The through hole 22 is formed at the center of the base plate 20. A plurality of fixing holes 24 are formed in the periphery of the through hole 22 As shown in FIG.

The base plate 20 is formed such that the head portion 18 is exposed through the through hole 22 in a state where the head portion 18 is exposed to the ground by using the main anchor 10 as described above, (18) can be coupled to the main anchor (10) in such a way that it fits into the through hole (22). For this purpose, the size of the through-hole 22 can be made smaller than the outer diameter of the head portion 18.

The plurality of fixing holes 24 are disposed in the periphery of the through holes 22 and are arranged such that the fixing holes 24 are positioned near four corner points in the case of the base plate 20 having a rectangular planar shape as shown in FIG. . A screw may be formed on the inner circumferential surface of the fixing hole 24. When the bolt 50 is inserted into the fixing hole 24 formed with the screw as described above, (1) can be installed.

The base plate 20 according to the present embodiment is characterized in that a plurality of sub-nuts 26 are radially joined to the periphery of the through holes 22. [ Since the plurality of fixing holes 24 are perforated around the through hole 22 as described above, the sub nut 26 can be coupled to be positioned between the fixing holes 24. For example, when the fixing holes 24 are located near the four corners of the rectangular base plate 20 as shown in FIG. 4, the subnuts 26 are coupled to be positioned near four edges .

Since the sub nut 26 is a component that is fastened so that the sub anchor 40 passes through as described later, a hole or groove (refer to 'R' in FIG. 4) So that the sub-anchor 40 does not interfere with passing through the sub-nut 26. Or the sub-nut 26 may be coupled outwardly to the edge of the base plate 20 so as not to interfere with the penetration of the sub-anchor 40.

The sub-nut 26 may be coupled to the base plate 20 by welding or the like. When the sub-nut 26 is engaged, the sub-anchor 40 described later is inserted in the direction in which the nut hole of the sub-nut 26 is perforated. Therefore, the direction of the nut hole of the sub nut 26 determines the entry direction of the sub anchor 40 (see 's' in FIG. 2).

The sub-nut 26 according to the present embodiment is formed such that the direction of the nut hole is inclined so as to form a predetermined angle (see 'a' in FIG. 2) with respect to the entry direction of the main anchor 10 (20). That is, by joining the sub nut 26 in an inclined manner, the type direction of the sub anchor 40 can be made to be a predetermined angle with the type direction of the main anchor 10.

The sub anchor 40 is a component that is installed to be screwed into the sub nut 26 and inserted into the ground. The sub-anchor 40 is inclinedly inserted into the ground by inclining the sub-nut 26 as described above. By providing the sub-anchor 40 so as to form a predetermined angle with the entering direction of the main anchor 10, The plate 20 can be firmly fixed to the ground.

The sub anchor 40 according to the present embodiment may be installed at an angle of 30 degrees (or 40 degrees, or 45 degrees) or more from the entering direction of the main anchor 10. [ To this end, it is possible to engage with the base plate 20 at an inclined angle of the sub-nut 26 as described above.

Since the angle formed by the sub anchor 40 and the main anchor 10 is about 90 degrees when the main anchor 10 is vertically installed in the ground and the sub anchor 40 is lying horizontally on the ground, The angle formed by the entering direction of the sub anchor 40 and the entering direction of the main anchor 10 may be 30 to 90 degrees (or 45 to 60 degrees).

The head portion 18 of the main anchor 10 is exposed through the through hole 22 of the base plate 20 when the main anchor 10 is installed and the base plate 20 is installed. In this state, the main nut 30 can be fastened to the head portion 18. When the main nut 30 is fastened, the main nut 30 presses the base plate 20 so that the base plate 20 is pressed on the ground. For this purpose, the size of the through-hole 22 can be smaller than the outer diameter of the main nut 30.

A plurality of cut-outs 16 may be formed radially as shown in FIG. 1 at a portion where the tip portion 14 is coupled to the end of the main anchor 10. The section 16 is for later expanding the body 12. After the main anchor 10 is typed in the ground, the tip portion 14 is further tapped and separated from the end of the body 12 in the paper, The end of the body 12 can be widened so that a plurality of incisional incisions 16 can be widened by using a device such as a pipe (see Fig. 6). When the end of the main anchor 10 is widened in the ground, the ground resistance of the main anchor 10 can be improved because the resistance of the ground is greater when the main anchor 10 is pulled out.

On the other hand, since the plurality of fixing holes 24 described above are formed with screws on the inner circumferential surface, a plurality of bolts 50 can be fastened to the plurality of fixing holes 24, respectively. 3, when the plurality of lining nuts 52 are fastened to the plurality of bolts 50 before installing the ground structure 1, the ground structure 1 Of the lining nut 52 is supported by the lining nut 52.

That is, when the structure 1 is installed such that the computer bolts 50 are inserted into the holes formed in the bottom surface of the ground structure 1, a plurality of lining nuts 52 are supported by the bottom surface of the structure 1 . In this state, when the degree of fastening of the lining nut 52 is adjusted, the supporting height of the structure 1 is changed. As a result, the level of the ground structure 1 can be adjusted by adjusting the lining nut 52.

As described above, when the horizontal structure of the ground structure 1 can be adjusted by using a separate component (lining nut 52), it is not necessary to align the foundation structure (base plate 20) The difficulty of the construction becomes easy, and the cost and time can be reduced.
