Description

The utility model relates to the covers of concrete wells and can be used as a cover for concrete wells.

A technical problem with all known manhole covers is that they are made of metal.

Reinforced concrete products are known in the art Concrete cover with a hatch (for example, https://zv.market/catalog/stroitelnye-materialy/zhbi/kryshki-dlya-kolodtsev/kryshki-dlya-kolodtsev-s-lyukom/zhbi-betonnaya-kryshka-s -lyukom-diametrom-lm /). A well cover with a hatch is a round reinforced concrete slab with a hole. Covers differ in outer diameter, height, hole size. This is an important structural part of the collection well, it is installed directly on the ring, fixed with cement mortar. For convenience, the products are equipped with mounting hinges.

The technical problem of this kind of solutions is that the upper part of the cover is concrete, which is heavy, technologically complex and expensive, and a crane is needed to install it.

In addition, metal hatches are used in this cover. To open them, you need to remove the entire lid, which is inconvenient and requires considerable physical strength of the employee.

These problems are partially solved in various types of hatch covers with opening doors, which provide the convenience of partially opening the hatch without removing the entire cover.

So, the manhole cover is known according to the patent US 2016168818, publ .: 2016-06-16, attached on hinges. The hatch door is metal, has slots for draining water and light. It can be open and half-open due to the presence of hinges in the middle part of the cover, which is divided into two semicircles.

Also known from the prior art is a manhole cover according to patent CN106592641, publ .: 2017-04-26, which can be in the open and semi-open state due to the presence of hinges in the middle part of the cover, which is divided into two semicircles. Similar solutions are described in patents: CN202830982 (publ: 2013-03-27), CN 201193329 (publ: 2009-02-11).

The closest analogue is the manhole cover according to the patent CN203654325 (publ .: 2014-06-18), which describes the hatch, consisting of two semicircles hinged to each other.

The technical problem of this kind of solutions is that the hatches are metal, are heavy, technologically complex, and even partial opening of them also requires considerable physical strength of the worker.

The task of the utility model is to eliminate the indicated technical problems.

The technical result of the utility model is the elimination of the need to use a concrete cover, a reduction in the weight of the structure, ease of manufacture and installation, and availability of low physical strength to workers.

The specified technical result is achieved due to the fact that the claimed cover of a concrete well having a hatch consisting of two semicircles hinged to each other, characterized in that the hatch itself is made of hard plastic and in the form of a cover, and the lower side of each of the semicircles of the hatch has semicircular grooves for shrinkage on the ends of the walls of the concrete ring of the well, and the articulated connection of the hatch semicircles is formed by hinges in the protrusions on the outside and consists of elements, each of which is a part of the semicircular hatch and forms a single cast part.

Preferably, the protrusions of the hinge joint are located along the diametrical line, with one protrusion of one semicircle of the hatch located between two other protrusions of the other semicircle of the hatch.

Preferably, stiffeners are provided on the outer and inner surfaces of the hatch.

Stiffeners are made in the form of grooves.

Preferably, there are additional stepped stiffeners on the outer surface.

Implementation of the utility model

The cover of the concrete well has a hatch and consists of two semicircles hinged to each other (see Fig. 1 - Fig. 4).

The novelty is that the hatch itself is made of hard plastic and in the form of a cover, and the lower side of each of the semicircles 1 and 2 of the hatch has semi-circular grooves 3.1 and 3.2, respectively, intended for shrinkage on the ends 10 of the walls of the concrete ring of the well 11. The principle of shrinkage is shown in FIG. five.

The hinge connection of the semicircles 1 and 2 of the hatch is formed by hinges 9 in the protrusions on the outer side and consists of elements 4 and 5, each of which is part of the semicircular hatch 1 and 2 and forms a single cast part with them.

The elements of the protrusions 4 and 5 at the interface form a drainage ridge preventing the ingress of water masses from outside.

Replacing a metal cover with a plastic one, which can be made by stamping, press-molding or rotomolding, eliminates the need to use a metal cover, reduces the weight of the structure, and is easy to manufacture and install (since technical devices are not needed due to the light weight of the cover), and also the availability of low physical strength workers in use (also due to the low weight of the plastic cover).

The protrusions 4 and 5 of the hinge joint can be located along the diametrical line, and one protrusion 4 of one semicircle 2 of the hatch is located between two other protrusions 5 of the other semicircle 1 of the hatch.

In order to increase the strength of the cover structure, as well as to reduce the weight of the cover itself, it is preferable that stiffeners 6 and 8 are made on the outer and inner surfaces of the hatch, respectively.

Stiffeners 6 and 8 can be made in the form of grooves.

To further enhance the strength of the lid structure, additional stepped stiffening ribs 7 can be made on the outer surface, for example, in the form of sector flats. They create a truncated cone shape for the cover, which distributes the load of the central zones of the cover to the peripheral sections that rest on the end 10 of the well 11.

Stiffening ribs 6, 7 also act as drainage grooves.

The applicant made a prototype of the product, which showed the reliability and strength of the structure (see Fig. 6), the ability to withstand a significant weight of the load, and at the same time ease and simplicity in installation. The movable part of the cover opens 180 ° (see Fig. 7), lying on the stationary part with one movement of the hand and without much effort.

In the process of manufacturing the lid, the assembly of the two parts of the lid is carried out at the end of the shaping process (hot). Then the finished product is packed folded for easy transportation.
