Description

one

The invention relates to the field of construction and concerns the construction of screw anchors used to secure a peat deposit to mineral soil.

Known screw anchor containing the trunk attached to it with a screw blade 1.

The disadvantage of this anchor is that when the anchor is immersed in the ground, a cable release attached to the anchor is wound on the barrel.

A screw anchor is also known, which includes a barrel with a conical tip and a screw blade, and a rotary sleeve with eyelets for attaching the cable ties 2. This screw anchor is closest to the described invention.

A disadvantage of the known anchor is that when it is wrapped in the ground, a cable lanyard attached to the rotary sleeve is not installed at the right angle to the barrel of the screw anchor, but is located near it.

In order to set the protrusion at the desired angle to the trunk, to the rest on

the surface of the soil end of the cable pulls the load, under the action of which the pulling should cut through the soil and take the desired position. However, it is practically impossible to install the pulling in the required position in this way, since for this it is necessary to apply large forces to it, which requires special devices; • whether the mechanisms, in their absence, it is necessary to cut a gap in the ground for stretching. This is usually done manually and is labor and time consuming. The purpose of the invention is to provide installation of the tails at a given angle to the barrel of the anchor.

This is achieved due to the fact that a screw anchor comprising a barrel with a conical tip and a helical blade and a bore. A mouthpiece with lugs for fastening cable pulls is provided with vertical elements in the form of right-angled triangles, each of which is adjacent to the barrel with a roll and facing one of the peaks of the acute angle to the tip, and additional sleeves to which are rigidly attached to the ends adjacent to the trunk of the leg of each vertical element, with the edge of the hypotheuse yaZhdogo; The vertical element is made with a longitudinal groove for the placement of cables and cables, and the bent hole is equipped with plates covering the bore of the rotary sleeve. FIG. 1 shows a general view of the proposed screw anchor, screwed into the ground; in fig. 2 is a view A of FIG. ; in fig. 3 - section B - B in FIG. one; in fig. 4 - section B - B in FIG. 1 and in FIG. 5 - section G - G in FIG. I. The screw anchor contains a cylindrical shaft 1 with a conical tip 2, a screw blade 3, a rotatable sleeve 4 C with eyelets 5 and attached to it by rope wires b mounted on the barrel with the possibility of rotation around its axis, rings 7 and 8, limiting the axial moving the rotary sleeve 4, the vertical elements 9 (according to the number of legs) in the form of right-angled triangles rigidly connected to each other along one of the legs by means of additional sleeves 10 and P. lnymi grooves 12 for receiving; in them, the stitch 6, the lamellae 13 and the fingers 14, and one of the vertical elements in the lower part is provided with plates 15, covering one of the openings 5 of the rotary sleeve 4. The upper end of the barrel is provided with a hole 16, a finger 17 and the sleeve 18. production- .. -: dits with ice image. , ..,. ,,.

Next, a sleeve 18 is installed on the bore of the GERD and a finger 17 is inserted into the hole 16. After this, the anchor is screwed into the underlying mineral soil to a predetermined depth. In this case, the vertical elements 9 do not rotate, and together with the delays 6 are pressed into the ground and the delays are set at the right angle to the barrel of the anchor. After that, the pin 17, the sleeve 18 are removed and the fingers 14 are pulled out of the holes 13. Next, vertical elements 9 are removed from the barrel of the anchor. labor costs for the installation of a screw anchor with tension in general. Claims An inventive screw anchor comprising a barrel with a conical tip and a helical blade and a rotatable sleeve with webs for attaching cable puffs, characterized in that, in order to provide installation of the trigger at a predetermined angle to the trunk, the anchor is provided with vertical elements in the form of right-angled triangles , each of which accepts a catheta to the trunk and faces one and the: angles of the acute angle to the tip and additional sleeves placed on the trunk, to which are rigidly attached with the ends adjacent to the trunk to theta each vertical member, wherein each edge hypotenuse BepTHKajTbHorq vsholnena element with a longitudinal groove for receiving a rope Ott rods, and one of the vertical plates provided ele.mentov covering prouschinu povGorotnoy sleeve. , Sources of information, taken into account in the examination 1.
