Abstract

FIELD: construction; public utilities; agriculture.

SUBSTANCE: invention can be used in the creation of fences, fences and supports. A pile support with height adjustment consists of two components: underground - a conical driven pile made of two trapezoidal plates bent at an angle of 90 degrees and welded together, forming ribs, and a ground part in a form of a pin with an external thread and a locking locknut that provide adjustment of the pile height, the fastener connected to the upper part of the pin, which provides fastening to the base of the structure being erected.

Description

The invention relates to the field of construction, public utilities or agriculture and can be used in the creation of fences, fences and supports for various purposes.

The Pylex Spytekdeck 44 support was chosen as the closest analogue - the prototype. This support, designed to support a patio, barn or terrace, is easier to install and more economical than a concrete load-bearing block. Its adjustable head makes it easy to level the floor during construction. The support is designed for rough or steep terrain. Its stabilizing anchor hooks allow you to return to its original position after ground movement (freeze, thaw), and the steel construction provides high strength. The height can be adjusted up to 3 inches. Baked powder coating provides excellent rust resistance (https://pylex.com/en/produit/spytekdeck-44-black/, published 2019)

The main disadvantage of this support is that the support is hollow inside and the pin inside is subject to longitudinal play, which does not allow to withstand significant lateral loads of the structure under construction.

The objective of the invention is to develop a reliable driven pile with height adjustment, easy to install.

The technical result of the invention is the possibility of multiple use, this pile allows you to withstand significant lateral loads of the structure under construction.

The technical result is achieved by the fact that a pile support with height adjustment, consisting of two components: underground: a conical driven pile made of two trapezoidal plates bent at an angle of 90 degrees and welded together, forming ribs, and a ground pin with an external thread and a fixing locknut that provides adjustment of the pile height, a fastener connected to the upper part of the pin that provides fastening to the base of the structure under construction, according to the invention, the underground part additionally contains a restrictive plate welded from above to the ribs with a hole in the middle for connecting the constituent parts of the pile, the area of which exceeds the area of the upper of the conical base of the underground part, and also additionally contains a pipe up to 30 cm long with an internal thread welded to the ribs of the conical underground part and to the inner side of the restrictive plate.

In FIG. 1 shows a driven cone pile consists of two components: ground and underground. The ground part of the pile consists of a pin with an external thread 1, a lock nut 2 and a fastener 3 (the types of the fastener are shown in Fig. 9, 10, 11, 12). The underground part of the pile consists of a restrictive plate 4 with a round hole in the middle 5 (Fig. 1, 3), a hollow pipe with an internal thread 6 (Fig. 1, 2, 3). The underground part of the pile is made of two trapezoid plates of sheet iron with a thickness of 1.5 to 5 mm, bent at an angle of 90 degrees and welded together.

A driven pile of square section is shown in Fig. 4 and also consists of two components: ground and underground. This pile additionally contains a square-section liner 7 (Fig. 6, 7, 8) with a base plate 8 (Fig. 6), and in the restrictive plate 4 a square-section hole 5 (Fig. 5). The size of the support plate 8 exceeds the size of the square hole 5 in the restrictive plate 4, which prevents the insert from falling through and turning inside the underground part of the pile (Fig. 5).

In FIG. 5 shows views of screw piles with a square section head, consisting of the same elements as in a driven pile of square section, namely, a pin with an external thread 1, a lock nut 2 and a fastener 3 (Fig. 9, 10, 11, 12) , a restrictive plate 4 with a square hole in the middle 5, a hollow pipe with an internal thread 6, a square insert 7 with a base plate 8 and a square pile head 9.

The device works as follows:

Piles are mounted in any soil: dense, medium - dense, stony, sandy. The choice of the type of pile and its size depends on the technical characteristics of the structure erected on top of this foundation, as well as the characteristics of the soil of the area. They are not affected by freezing, buckling and shrinkage of the soil. They can be used repeatedly, and during their installation the integrity of the surface of the site does not deteriorate. This pile design is designed for installation on a surface with a height difference of up to 300 mm.

The pile is driven or screwed into the ground up to the restrictive plate 4, which is made larger than the upper part of the blade of the pile itself, which makes it possible to prevent the pile from sinking into the ground under load. The ground part of the pile is inserted into the hole 5 in the restrictive plate 4, consisting of a pin with an external thread 1, which is screwed into a pipe with an internal thread 6 of the underground part of the pile. This connection eliminates the longitudinal backlash between the components of the pile, which is present in the prototype. This allows you to increase the reliability of the structure under construction.

The pin 1 is screwed in to a given pile height and fixed with a lock nut 2. This makes it possible to set the required height for mounting the lower chord (strapping) when mounting on a surface with a height difference of up to 300 mm.

After that, the lower belt (strapping) is mounted to the fastener 3, which is the base of the structure being erected.

The use of the connecting unit: a pipe with an internal thread 6 and a pin with an external thread 1 in driven cone piles, and in driven piles of square section and screw piles with a square head, the unit additionally contains an insert 7 with a support plate 8, which allows the structure to withstand significant lateral loads .

During installation, either a mobile pneumatic, hydraulic press or hand tool is used. Driven piles are dismantled using a tool, as a rule: a crowbar, a nail puller, a piece of pipe, by installing it under the restrictive plate and using the lever method, the underground part of the support is removed from the ground. A screw pile is a method of twisting them out of the ground. This allows you to reuse these piles.

All known screw piles are cut off at the end of twisting. The cut height is performed according to the design height of the base of the structure being erected, which practically excludes the possibility of reuse, since the lengths of the piles will be different. The use of driven cone piles is limited to their use only when mounting fence posts.

Experimental studies have shown that the claimed invention significantly reduces material, labor and time costs and allows you to independently perform quick, easy installation and dismantling of piles, in comparison with known ones.

Thus, the claimed invention, through the use of a connecting assembly of a pin with an external thread and a bolt with an internal thread, as well as an insert with a supporting platinum, makes it possible to withstand significant lateral loads of the structure under construction. The possibility of multiple use of these piles. The use of a height adjustment unit in the invention makes the product much more functional.
