Abstract

Anchor device includes a rod with a slat at its lower end, and at least one anchor with rotary blades. Anchor is made as put on the rod the lower and the upper pipe elements with at least two rigidly fixed on those ribs. Each rotary blade is with its one end hinged to the rib of the lower pipe element and with its middle part, through a lever, it is hinged to the rib of the upper pipe element; at the outer ends of the pipe elements supports are provided. High bearing ability of the anchor is achieved, at large side loads, and possibility of application with calculated load directly after installation.

Description

The invention relates to construction and can be used in the construction of objects with the need to perceive a significant lateral load.

A well-known soil anchor (Author's certificate of the USSR Mo 1791540, publ. 30.01.93, bull. Mo4), which includes a tubular body placed in the soil with a tip and rotating blades attached to the body and a draft in the form of a pipe for feeding cement mortar into the soil. The disadvantage of this design is the long duration of production due to the need for a long exposure time for the cement mortar to harden and insufficient bearing capacity for significant lateral loads.

A well-known ground anchor (Russian Patent Mo2029823, publ. 27.02.95, Mob. Bull.), which includes a rod and a pair of rotating blades fixed to the rod with a finger and brackets. The thrust is made with a stop.

The disadvantage of such an anchor is also insufficient bearing capacity for lateral loads.

The invention is based on the task of creating an anchor device that, due to new structural elements and connections between them, would allow to ensure a high load-bearing capacity of the anchor with significant lateral loads and the possibility of using it with the calculated load immediately after installation.

The task is achieved by the fact that in the anchor device, which includes a rod with a bar at the lower end and at least one anchor with rotating blades, according to the invention, the anchor is made in the form of lower and upper tubular elements put on the rod with at least two ribs rigidly fixed on them , each rotating blade is hinged at one end to the edge of the lower tubular element and the middle part is hinged to the edge of the upper tubular element through a lever, stops are made on the outer ends of the tubular elements.

The task is also achieved by the fact that, according to the invention, the device contains two or more anchors, put on the rod, and by the fact that the anchors are turned along the rod by 45" relative to each other.

Figure 1 shows an anchor device with an anchor in a folded state; in Fig. 2 - with an anchor in working condition with fully spread blades.

The anchoring device consists of a rod 1 with a bar 2 at the lower end. The lower C and upper 4 tubular elements with ribs 5 rigidly attached to them are put on the rod 1.

The rotating blade 6 is hinged at one end to the rib 5 of the lower C tubular element, and the middle part is connected to the rib 5 of the upper 4 tubular element by means of the lever 7. Stops 8 are made on the outer ends of the tubular elements C and 4. To bring the anchor into working condition, the inventory tube 9 is put on the rod 1.

The anchor device works in the following way.

The anchor is immersed in a drilled well in a folded state. At the same time, the distance between the tubular elements 3 and 4 is maximum and the blades 6 are adjacent to them. An inventory tube 9 is put on the rod 1, which ensures the transfer of compressive force to the tubular elements C and 4 of the anchor. Due to this effort, the distance between the elements decreases and the blades 6 are pushed apart, entering into contact with the ground. The inventory tube 9 is pulled out and a pulling force is applied to the rod 1, which ensures the complete convergence of the tubular elements C and 4 and the complete opening of the blades 6.

After tensioning, the well is filled with cement mortar or, depending on the ground conditions, cement mortar is injected under pressure using cuff pipes.

To increase the bearing capacity of the anchor device with significant lateral loads, depending on the soil, it is possible to use several anchors on one beam. Also, to ensure the necessary load-bearing capacity, the anchors can be rotated relative to each other along the axis by 45".

The proposed design allows you to use the anchor device immediately after its installation with the calculated load, without waiting for the cement mortar to gain strength. Also, the possibility of using several anchors on one beam makes it possible to ensure the necessary load-bearing capacity of the anchoring device on the ground, depending on its condition. 2 5 6 5 and : -8- in
