Description

domain of technology

The utility model relates to the field of construction, namely to the construction of mushroom-shaped foundations and can be used in the installation of overhead power lines for the construction of foundations for metal, reinforced concrete or combined racks, or supports.

State of the art

The closest analogue of the claimed utility model is the mushroom-shaped foundation disclosed in the patent of the Russian Federation for utility model RU 154946, 09/20/2015. The foundation includes a base plate and a stand connected by a keyway-groove connection. The base plate has two embedded elements in the form of protruding corners forming grooves for accommodating the rack embedded elements, which also have the shape of corners, with the formation of a spike-groove connection. In this case, the protruding parts of the embedded elements freely pass into the groove of the response elements, and two connecting rods are introduced between the embedded elements.

The disadvantage of this design is the relative complexity of installing the rack in the foundation, associated with the need to drive the rods.

Utility Model Disclosure

The objective of the claimed utility model is to eliminate the shortcomings of known analogues and to develop a mushroom foundation that provides easy installation and installation of elements while maintaining strength and other functional characteristics of the structure.

The technical result of the utility model is to simplify the assembly and installation of the foundation.

The specified problem is solved, and the technical result is achieved due to the fact that the mushroom-shaped foundation contains a base plate and a stand connected to it, made tapering to the top; the base plate is provided with two horizontal keyways, and the rack in the lower part on both sides is equipped with horizontal protrusions located in these keyways; moreover, the horizontal protrusions of the rack have a wedge-shaped profile with a narrowing in the direction peripheral relative to the axis of the rack and are placed in the keyways with direct contact of their outer surface with the inner surface of the keyways having geometry corresponding to the horizontal projections of the rack.

In addition, according to private options for implementing the utility model:

- the base plate has vertical protrusions, while the keyways are made in these vertical protrusions;

- the base plate in the Central part has an upper supporting surface that mates with the side surfaces along inclined faces, while the vertical protrusions are made on the specified supporting surface.

- the rack can be made of reinforced concrete or metal material;

- the rack may have a rectangular or I-beam cross section;

- the rack can be made vertical or inclined.

In contrast to the closest analogue, the device under consideration uses a stand having wedge-shaped protrusions that form keys for placement in the reciprocal grooves of the foundation with direct contact of the surfaces of the connected elements. This difference allows for simple installation without the use of additional operations for the mutual fixing of the foundation elements (driving rods, installing bolts, etc.).

The described special cases of the implementation of the structure are also aimed at simplifying the installation of the structure. However, they are not the only possible embodiments of the utility model. Moreover, the technical result of the utility model is achieved without the use of these additional features.

It should be noted that the utility model also provides additional benefits associated with increased reliability and durability of the structure. In particular, the proposed design allows to reduce the corrosion effect due to the lack of contact of metal elements with the external environment.

Brief Description of the Drawings

The design of the claimed device is illustrated by drawings, where:

in FIG. 1 shows a view of the claimed foundation assembly;

in FIG. 2 shows the elements of the foundation;

Utility Model Implementation

The claimed foundation includes a base plate (1) and a vertical or inclined rack (2) mounted on it.

The base plate (1) preferably has a prismatic shape with an elevation in the form of a horizontal supporting surface (3), mating with vertical surfaces (4) along inclined faces (5) with the formation of trapezoidal end faces (6).

On the supporting surface (3) two vertical protrusions (7) are made in the form of corners with an inclined base and cantilever horizontal hooks directed to each other. These protrusions (7) are preferably integral with the main part of the base plate (2). The protrusions (7) form the keyways (8) for attaching the rack (2). These grooves have a wedge-shaped, and more specifically trapezoidal profile, with a narrowing in the direction from the center of the plate (1). The base plate (1) can be made, preferably, of reinforced concrete.

The stand (2) can be made of steel or reinforced concrete.

Reinforced concrete stand, as a rule, is performed with a rectangular section and a trapezoidal run from the top to the base along one of the faces (narrowing to the top). The angle of inclination of said face is approximately equal to the angle of inclination of the face of the intermediate support.

The steel stand, as a rule, has an I-section with a smooth decrease in thickness to the top.

In the lower part of the post (2), two horizontal protrusions (9) are made from opposite sides, forming trihedral dowels of a wedge-shaped (trapezoidal) shape with a narrowing in the direction peripheral to the axis of the post. The outer surface of the horizontal protrusions (9) of the uprights (2) has a geometry that corresponds to the geometry of the inner surface of the keyways (8) of the base plate (2) so that the protrusions (9) are placed in the grooves (8) with direct contact along all three faces .

In the case of a rack (2) made of reinforced concrete, a metal (steel) head (10) can be installed in its upper part, welded to a metal embedded part of the rack (2). Possible versions of the head (10) are rotated through an angle of 45 ° at the axis of the support beam. The base plate of the head (10) can have 4 round holes for installing the bolts securing the support to the foundation rack.

When performing a rack of metal material in the upper part, it may have a flange for attaching the support.

The rack (2) is mounted on the base plate (1) by horizontal placement of the projections (keys) of the rack into the keyways of the plate. At the same time, to increase the adaptability of the installation process and ensure tight contact of the protrusions with the grooves, a reusable mounting device can be used.
