Ground Anchor

Abstract

A ground anchor having a head and anchoring elements in the form of pipes or rods, wherein the ground anchor comprises an anchor head (5) which has a polygon or an ellipse cross-section, the upper part of which is open or closed with at least one opening having a head socket (7), said ground anchor contains at least two anchoring elements (6) in the form of pipes or rods passing through at least two at an angle to the vertical axis of the anchor head and anchoring element guides fixed to the anchor head (3) wherein the anchoring element guides have a hole or holes (4) for blocking the anchoring element through, wherein a screw or screws (8) lock the anchoring element passes and wherein the head socket (7) has a hole or holes (9) for locking the fastening element (1) with self-tapping screws (2).

Claims

1. A ground anchor having a head and anchoring elements in the form of pipes or rods, characterized in that in the anchor head with a polygon or an ellipse cross-section the upper part is open or closed with at least one opening having a head socket, contains at least two anchoring elements in the form of pipes or rods passing through at least two at an angle to the vertical axis of the anchor head and anchoring element guides fixed to the anchor head where the anchoring element guides have a hole or holes for blocking the anchoring element through which the screw or screws that lock the anchoring element passes and the head seat has a hole or holes for locking the fastening element with self-tapping screws.

2. The ground anchor according to claim 1, characterised by the fact that it has two guides of the anchoring element and two anchoring elements.

3. The ground anchor according to claim 1, characterised by the fact that it has three guides of the anchoring element and three anchoring elements.

4. The ground anchor according to claim 1, characterised by the fact that it has four guides of the anchoring element and four anchoring elements.

5. The ground anchor according to claim 1, characterised by the fact that the cross-section of the head socket is in the shape of a polygon.

6. The ground anchor according to claim 1, characterised by the fact that the cross-section of the head socket is in the shape of an ellipse.

7. The ground anchor according to claim 1, characterised by the fact that the cross-section of the guides of the anchoring element is in the shape of a polygon.

8. The ground anchor according to claim 1, characterised by the fact that the cross-section of the guides of the anchoring element is in the shape of an ellipse.

9. The ground anchor according to claim 1, characterised by the fact that the cross-section of the anchoring element is in the shape of a polygon.

10. The ground anchor according to claim 1, characterised by the fact that the cross-section of the anchoring element is in the shape of an ellipse.

11. The ground anchor according to claim 1, characterised by the fact that in the socket head is an element for height adjustment on which is mounted an adapter for attaching said fixed element.

Description

[0008] The subject of the invention is shown in the drawing where FIG. 1 presents an anchor with four guides in a general view, FIG. 2 presents an anchor with four guides in a side view, FIG. 3 presents an anchor with four guides in a plan view, FIG. 4 presents an anchor with three guides in a general view, FIG. 5 presents an anchor with three guides in a plan view, FIG. 6 presents an anchor with two guides in a general view, FIG. 7 presents an anchor with two guides in a plan view, FIG. 8 presents an anchor for large loads or low load bearing land, FIG. 9 presents an anchor with adapter and height adjustment, FIG. 10 presents an anchor with a head for direct fixing of the fixed element. Designation of figure elements: 1—fixed element, 2—the lock screw height of the fixed element, 3—guides of the anchoring element, 4—hole for blocking the anchoring element, 5—an anchor head, 6—anchoring element, 7—head socket, 8—the lock screw of the anchoring element, 9—hole for locking the fixed element, 10—ground level, 11—element for height adjustment, 12—adapter for attaching fixed element.

[0009] The main element of the anchor is the anchor head 5, which is fixed in the ground by driving steel pipes or rods 6, passing through the guides 3 of the anchoring element 6 attached to the anchor head 5. These guides are placed at an angle to the vertical axis of the anchor head, allowing the force needed to move the entire anchor in any direction is multiplied. In the upper part of the anchor head there is also a head socket 7, in which is fastened the fixed element 1—e.g. a fence post, road sign, platform support, etc. (FIG. 1). The fixed element 1 can also be inserted directly into the anchor head—then the anchor head is not closed by the head socket (FIG. 10). The anchor element guides and the head seat are welded to the anchor head. The guides have holes 4 for blocking, by means of the lock screw 8 the anchoring elements, the possibility of the head moving relative to the inserted anchoring elements (e.g. pipes) after setting the end position of the anchor. Allowing this, we have the possibility of very precise settings, e.g. the height of the fence post or the height of the platform, terrace, etc. Depending on the anticipated force needed to fix a given fixed element and the type of soil, the anchor can be found in various sizes, number of guides, length of driven pipes. The anchor head is made in a way that enables fixing a given type of structural element (e.g. for a square post for system fences or for a road sign). The anchor head can also be made as a head with the option of mounting an additional adapter 12 for fixing of the fixed element. In this case, is inserted into the head of the head 7 an element 11 for adjusting the height (e.g. a screw), which makes it possible to adjust the mounting level of the fixed element (e.g. for attaching a wooden pole or for mounting the extraction rope). Due to the fact that only pipes (rods) passing through the guides are driven, no risk of damaging the anchor head or (what is more important) the fixed element is made at any time during the anchor assembly. Fixed element inserted in the socket in the anchor head, set roughly to the vertical and using a hammer or a special attachment for the rotary hammer we drive through the guides of the steel pipe head. After sinking the pipes at full depth, we set the anchor exactly to the vertical and block the position of the head by screwing the appropriate number of self-tapping screws into the pipes through the holes in the head guides. Then insert or extend the fixed element in the head to the desired height and block its position by means of self-tapping screws screwed into the element through the hole in the head seat.
