Description

The technical field to which the utility model belongs.

This utility model relates to the field of construction, and more specifically to the connecting elements of the rope and the supporting structure, mainly the ground anchor, including a metal body having a first section of attachment to the rope and a second section of attachment to the ground anchor and is intended for fastening steel ropes of mesh fences for protection against avalanches, snow or mountain collapses to anchor fixed on the ground.

The level of technology.

The prior art connection element of the rope and the supporting structure, including a metal body having a first section of attachment to the rope and a second section of attachment to the supporting structure described in the patent of the Russian Federation for utility model No. 158018, published in 2015.

This level of technology is the closest in technical essence to the claimed utility model and is taken as a prototype to the proposed utility model.

The disadvantage of this prototype is the inability to absorb energy from dynamic (shock) exposure.

Disclosure of a utility model.

Based on this original observation, the present utility model mainly aims to propose a connecting element of the rope and the supporting structure, including a metal body having a first section of attachment to the rope and a second section of attachment to the supporting structure, allowing at least to smooth at least , one of the above disadvantages, namely, to ensure the leveling of negative effects from dynamic (shock) effects, as well as equalization or redistribution of load in two parallel installed ropes, which is the technical task of the utility model.

To achieve this goal, the first section of attachment to the rope is made in the form of a deformable element made of rolled steel, which at one end forms a loop for attachment to the rope, and the second end passes, passing around, through a series of axes located on the body.

Thanks to this advantageous characteristic, it becomes possible to use the deformable element as an energy absorber, since it takes on the impact on the ropes and dampens it by stretching.

There is an advantageous embodiment of the utility model, in which the housing is made in the form of a central supporting plate and one external restrictive plate interconnected by threaded fasteners forming axes.

Thanks to this advantageous characteristic, it becomes possible to implement the proposed site in a specific way.

There is also such an advantageous variant of the utility model, when the casing is made in the form of a central supporting plate and two external restrictive plates interconnected by threaded fasteners forming axes

Due to this advantageous characteristic, an alternative opportunity appears for another variant of the specific implementation of the proposed site.

There is another advantageous variant of the utility model, in which at least several axes have rollers located on them, around which a deformable element is located

Due to this advantageous characteristic, it becomes possible for the deformable element to slip around the rollers when pulled.

Finally, there is a variant of the utility model in which the deformable element has a locking loop.

Due to this advantageous characteristic, it becomes possible to stop the deformable element at the end of the drawing and create an additional possibility of energy absorption.

The set of essential features of the proposed utility model is unknown from the prior art for devices of similar purpose, which allows us to conclude that the criterion of "novelty" for the utility model is met.

According to figures 1-7, the connecting element of the rope 1 and the supporting structure, mainly soil anchor 2, including a metal casing having a first section of attachment to the rope 1 and a second section of attachment to the soil anchor 2.

The first section of the attachment to the rope is made in the form of a deformable element 3, of rolled steel, which at one end forms a loop for attachment to the rope 1, and the second end passes, passing around, through a series of axles 4 located on the body.

Rolled steel can be round, square or rectangular.

The housing is made in the form of a central carrier plate 5 and one external restrictive plate 6, interconnected by threaded fasteners forming axes 4.

The housing is made in the form of a central carrier plate 5 and two external restrictive plates 6, interconnected by threaded fasteners forming the axis 4.

At least several axles 4 have rollers 7 located on them, around which a deformable element 3 is located.

The rollers 7 are plain bearings.

The deformable element has a locking loop 8.

The arrows in figure 7 show the installation location of anchors with energy absorbers on the ropes of the grid suspension (catching structural element) and guy wires.

The connecting element is installed in the gap between the anchor 2 and the steel rope 1 and is intended to convert the energy of a moving (captured) object into mechanical work to change the shape of the deformable element 3.

The main feature in the proposed design is the use of ordinary steel products of round, square or rectangular section as a plastically deformable element with a workpiece length of up to 6 meters, while this element is not subjected to any other mechanical processing and welding, except for cutting into workpieces of the required length and bending it with a large radius (bending radius of at least 2 material thicknesses) to give the desired shape.

Implementation of a utility model.

The connecting element of the rope and the supporting structure is used as follows. (A non-limiting example of a utility model is given).

Stage 1. Install the proposed connecting element of the rope and the supporting structure in the fastening systems of steel ropes of mesh fences to protect against avalanches, snow or mountain collapses to the anchor fixed on the ground.

Stage 2. When the rock block acts on the barrier, the mesh and the ropes are simultaneously tensioned. The grid is fixed on racks and on the upper and lower ropes. Bearing ropes are fixed on soil anchors through the proposed site.

Stage 3. During the construction process, the force is transmitted from the block to the grid, further from the grid to the ropes and along the ropes to the anchors and supports, which, in turn, are held by cable ropes fixed to the anchors directly or through en. where the load has a shock character.

Stage 4. The deformable element bends around the rollers and when pulling it out of the body rolls along them, the rollers slide along the axes.

Stage 5. At the initial moment of operation of the barrier, the rope tension is greatest and exceeds the failure threshold, which is 60-90% of the tensile strength of the rope. Also, the energy of the moving debris will do the work in the energy absorber and decrease until it falls below the threshold value or completely develops the working length of the deformable element.

Industrial applicability.

The connecting element of the rope and the supporting structure can be carried out by a specialist in practice and, when implemented, ensures the implementation of the declared purpose. The possibility of being implemented by a specialist in practice follows from the fact that for each feature included in the utility model formula based on the description, the material equivalent is known, which allows us to conclude that the criterion of “industrial applicability” for the utility model and the criterion of “completeness of disclosure” for the utility model are met .

In accordance with the proposed utility model, the applicant made a prototype of the proposed connecting element of the rope and the supporting structure.

Pilot operation of the proposed connecting element of the rope and the supporting structure showed that it ensures the achievement of the technical result achieved - the restriction ("smoothing the force diagram") of the transfer of force from an inextensible rope to the anchor, leveling of negative impact from dynamic (shock) impact, as well as equalization or redistribution of load in two parallel installed ropes.
