Description

The proposed utility model relates to construction, namely, fixators for attaching geotechnical gratings to concrete blocks of retaining walls during the construction of roads and bridge supports.

Known application for the invention of the Russian Federation No. 97100186, IPC E02D 29/02, "SYSTEM OF MODULAR BLOCKS FOR THE FORMATION OF A SUPPORTING WALL AND METHOD FOR ITS CREATION". A modular wall block having a front surface, a rear surface, a lower surface and oppositely located side walls extending between the upper and lower surfaces and the front and rear surfaces, characterized in that a recess is formed in the upper surface for frictional reception of the first parts of the lattice connector for connecting a mesh-like a sheet of material with a modular wall block, and a groove is formed in the lower surface that interacts with other parts of the lattice connector received in recess, to accommodate the overlapping row of masonry wall blocks relative to the lower row of masonry wall blocks with a vertically centered or vertically offset orientation.

The disadvantage of this connector is its low versatility for connecting various types of geotechnical gratings with concrete blocks, as well as its complexity of installation and low reliability in fixing the position of the geotechnical lattice in concrete blocks of the retaining wall.

Closest to the claimed utility model is the RF patent for the invention No. 2353730, IPC E02D29 / 02, “ASSEMBLY OF THE GEOROUS LATTICE WITH THE SUPPORT WALL UNITS AND THE LATTICE CONNECTOR USED IN IT”. The invention relates to the construction and can be used in the construction of transport roads and bridge supports. The node connecting the geogrid with the retaining wall blocks contains a trellis connector having a hook and a finger-shaped element connected with the hook, a geogrid link having an aperture formed by transverse and longitudinal ribs, and a pair of blocks with at least vertically adjacent surfaces on the side of which in one block there is a recess, and the hook of the lattice connector is located in the recess of the block, and the finger-shaped element of the lattice connector is connected to one of the transverse ribs of the geogrid link through its hole. The hole of the geogrid link is made elliptical, the lattice connector is in the form of a finger-shaped element with a power part at one end and a tick-shaped gripper at the other, the tick-shaped gripper is connected through its hole in the geogrid link to its transverse edge, the lattice connector and the mentioned transverse rib of the geogrid are placed in the recess of the block, and at least one longitudinal edge of the geogrid link is brought out through the power portion of the finger-like element of the lattice connector. A trellised connector is also proposed. The technical result consists in increasing the reliability of the connection of structural elements, the accuracy of the assembly, reducing the complexity.

The disadvantage of this solution is the relatively small area of the support base, which is limited to two grips bent down, which reduces the overall reliability of fixing the geotechnical grid in the retaining wall.

In addition, there is inconvenience in the orientation of the connector when connecting it to the geosynthetic lattice as part of the retaining wall, since such a lattice, being located in the tapering jaws of the connector, is pinched at two points and it is difficult to rotate it for orientation with respect to concrete blocks when erecting the retaining wall.

The technical task of the proposed utility model is to improve the installation and operational properties of the connector.

The technical result, the improvement of the installation and operational properties of the connector, is achieved due to the fact that the connector consists of a support base with an inclined section, a middle finger with a grip equipped with an elongated tapering pharynx, making it possible to locate a geotechnical lattice in it. The connector is additionally equipped with two fingers located at the edges of the connector and limiting the length of the inclined portion of the support base. The two extreme fingers are made without grip and are equipped with a shortened pharynx with the possibility of supporting the geotechnical grid in it. The supporting base is made with the possibility of location in the concrete block retaining wall. The supporting base is made with a triangular protrusion, the upper corner of which is truncated, and its right and left sides are made with a bevel.

The essence of the utility model is illustrated by drawings:

FIG. 1. - General view of the connector.

FIG. 2 - Side view of the connector.

The connector 1 consists of a support base 2 with an inclined portion 3, a middle finger 4 with a gripper 5, equipped with an elongated tapering pharynx 6 with the possibility of location of a geotechnical grid in it. The connector 1 is additionally equipped with two fingers 7 located at the edges of the connector 1 and limiting the length of the inclined section 3 of the support base 2. The two extreme fingers 7 are made without grip and are equipped with a shortened shed 8 to enable support of the geotechnical grate in it. The supporting base 2 is made with the possibility of location in the concrete block retaining wall. The supporting base 2 is made with a triangular protrusion 9, the upper angle 10 of which is truncated, and its right and left sides 11 are made with a bevel 12.

The device operates as follows:

The connector 1 is placed in the recesses of the concrete blocks 14. The transverse edge of the link of the geotechnical grid 3 is placed and pinched in the elongated tapering pharynx 6 of the elongated grip 5 of the middle finger 4 of the connector 1 with emphasis on the shortened pharynx 8 of the extreme fingers 7 and resting on the supporting base 2. Other transverse links geotechnical gratings 13 have corresponding horizontal rows in other connectors. Bulk soil is placed between such rows, forming the supporting wall of the building structure.

The proposed connector used in the above-described connection node of the geotechnical grid with concrete blocks of the retaining wall is also used in other conditions, for example, to connect the geotechnical grid panels to each other when laying them on the canvas of the constructed road (not shown in Fig.).

The main advantage of the proposed connector over the prototype, which can significantly improve the installation and operational properties, is to reduce the pinching points in it of the geotechnical lattice and increase the area of its supporting base, while maintaining the reliability of the location of such a lattice on the supporting base of the connector.

The rejection of two grips allows pinching in the proposed connector of the geotechnical grid at one point instead of two. This provides ease of rotation of the geotechnical lattice pinched in the connector for convenient orientation with respect to concrete blocks during the construction of the retaining wall.

The location of the middle finger 4, between the extreme fingers 7, equipped with a shortened shed 8, provides a stable support of the geotechnical grid 13 in such fingers 4 and 7, which in turn ensures the reliability of the geotechnical grid 13 on the support base 2 of the connector 1.

Limiting the length of the inclined section 3 by the extreme fingers 7 provides an increase in the convenience of orientation of the connector 1 on the concrete blocks 14 of the retaining wall.

The location behind the extreme fingers 7 of the side parts adjacent to the inclined section 3 of the rest of the support base 2 provides an increase in the useful area of this base, which in turn increases the reliability of the location of the connector 1 in the retaining wall.

The supply of the supporting base 2 with bevels 12 provides the convenience of inserting the geotechnical grid 13 into the elongated tapering pharynx 6 of the middle finger 4 of the connector 1.

The connector is made of plastic by molding in appropriate forms.

Tests of the proposed connector made according to the following parameters:

- width b, length c, height h, respectively, 51, 52 and 18 mm, length d of the support base is 32 mm;

- the elongated tapering pharynx is formed by the conjugate rounding radii R1 and R2 of the bottom of the elongated grip, respectively 52 and 35 mm.

All of the above indicates the fulfillment of the technical task and the industrial applicability of the claimed device.
