Description

The utility model relates to the field of housing and communal services, road services and can be used as a hatch device that closes the entrance to underground engineering structures (water supply and sewerage networks, heat supply and drainage networks, telephone networks), which are located on sidewalks paved with paving stones or tiles, as well as on footpaths of park areas, where the landscape solution and the type of coverage play an important role, and can also be used on sports grounds, in industrial and domestic premises for a comfortable and smooth operation.

The closest technical solution (prototype) is a hatch device (RF Patent No. 151545, E02D 29/14, publ. 04/10/2015 Bull. No. 10), containing a body formed by the bottom and vertical walls that form the shape of a box located in the counterpart, equipped with support platforms formed by flat platforms rigidly fixed on the inner side of the walls of the counterpart of the hatch along its entire inner perimeter, a reinforcing frame placed inside the body and dividing the body into sections for filling with filler, glasses for placing special means for lifting the cover are located in the body box, there are two stiffeners.

Disadvantages of the prototype: reduced operational capabilities of the prototype, because:

1) the implementation of two stiffeners of small thickness and dimensions, which are located in the housing box, reduces the operational capabilities of the prototype, since the strength of the hatch is not ensured;

2) the presence of two glasses of a prismatic shape (without upper barriers), located in the middle of the housing box, reduces the operational capabilities of the prototype, because the possibility of filling them with filler is very high when filling the box of the body with filler;

3) the presence of only two glasses leads to the fact that the maintenance of the hatch is difficult, because a heavy hatch with a filler must be lifted by only one user, while the weight of the hatch may exceed the maximum permissible load on the human body;

4) the presence of four massive ebbs in the counterpart will make it difficult to dismantle the hatch if necessary;

5) the presence of four massive ebbs of the counterpart increases the material consumption of the prototype.

The technical problem solved by the creation of the claimed technical solution is that the existing structures (for example, metal) hatches used to protect underground engineering structures have low operational capabilities, they are made protruding above the surface of sidewalks or footpaths, therefore they can easily be crushed or displaced from their place, for example, by cleaning equipment due to the fact that their design is not able to ensure the uniformity of the sidewalk or pedestrian coverage. At the same time, the driver of the harvesting equipment is forced to bypass these hatches, creating a threat to pedestrian traffic and destroying the sidewalk superstructures. The use of such hatches contributes to the creation of situations that can lead to injuries due to falling into them of a person and an animal, which can arise, for example, due to vandalism or displacement of the hatch by cleaning equipment (for example, in the autumn-winter period of the year, snow cleaning), i.e. .to. these devices are devoid of locking elements, and also protrude above the surface of sidewalks or walkways.

The technical result of the claimed technical solution is to expand the operational capabilities of the hatch device.

The technical result is achieved in that the hatch device contains a body formed by the bottom and vertical walls that form the shape of a box located in the counterpart, equipped with support platforms formed by flat areas rigidly fixed on the inner side of the walls of the counterpart of the hatch along its entire inner perimeter, reinforcing a frame placed inside the body and dividing the body into sections for filling with filler, cups for accommodating the means for lifting the lid are located in the body box, there are two stiffeners, plates of steel sheet material are attached to the four corners of the vertical walls of the body, each of which has one a shaped hole of an oblong shape, under each of which there is a glass having a cylindrical shape, the height of which is equal to the distance from the inner surface of the plate to the inner surface of the bottom of the body, each reinforcing element of a curved U-shape located under each plate slime, made welded to its free generatrix with one end, and with the other two ends welded to the upper surface of the housing bottom, two U-shaped brackets are attached to two opposite outer surfaces of the vertical walls of the counterpart, two stiffeners are made fixed to the lower surface of the housing bottom , all structural elements of the body and the counterpart are separately made connected to each other by welding, all elements of the device are made of structural steel and covered with a corrosion-resistant coating. Moreover, the body and its counterpart are made of a square shape. Moreover, the plates of steel sheet material are made of a triangular shape and are attached to the four corners of the vertical walls by welding. Moreover, each shaped hole of an oblong shape, located in a triangular plate, is made parallel to the hypotenuse of the plate triangle. Moreover, the reinforcing frame of the body, the reinforcing elements of the curved U-shaped plates and the U-shaped brackets of the mating part are made of reinforcing steel bars. Moreover, a zinc coating can be used as a corrosion-resistant coating.

New essential distinguishing features of the proposed technical solution are the following features:

- plates of steel sheet material are attached to the four corners of the vertical walls of the body;

- each of the four plates has one shaped oblong hole;

- under each of the shaped holes of an oblong shape, there is a glass having a cylindrical shape, the height of which is equal to the distance from the inner surface of the plate to the inner surface of the bottom of the body;

- two U-shaped brackets are attached to two opposite outer surfaces of the vertical walls of the counterpart;

- two stiffening ribs are made fixed to the bottom surface of the bottom of the body;

- all structural elements of the body and the counterpart are individually made connected to each other by welding;

- all elements of the device are made of structural steel and covered with a corrosion-resistant coating.

The hatch device (Fig. 1, 2, 3, 4, 5, 6, 7, 8, 9) consists of a body 1 (Fig. 2, 3, 5) having a rectangular shape, and a counterpart 2 (Fig. 1, 2 , 7, 8, 9) of body 1 (Figs. 2, 3, 5). The body 1 is a removable cover in the claimed device of the hatch. The body 1, made without hinges, is formed by a rectangular bottom 3 (Figs. 2, 4) with vertical walls 4 located around it along the perimeter (Figs. 1, 2). The rectangular bottom 3 (Figs. 2, 4) of the housing 1 (Figs. 2, 3, 5) together with the vertical walls 4 (Figs. 1, 2) forms the form of a box. The vertical walls 4 are made with a height of, for example, 80 mm. The body 1 (Fig. 2, 3, 5) can have dimensions, for example, 750 × 750 mm.

Inside the body 1 there is a reinforcing frame 5 (Figs. 2, 3), which divides the inner space of the body 1 (Figs. 2, 3, 5) into sections. Reinforcing frame 5 (Fig. 2, 3) is made in the form of horizontal reinforcing bars 6, located at right angles to each other with the formation of sections. The reinforcing bars 6 of the reinforcing frame 5 are made welded to each other, for example, by means of semi-automatic welding in a gas atmosphere. Reinforcing frame 5 is designed to increase the resistance of the hatch cover - body 1 (Fig. 2, 3, 5) to external pressure, as well as to fill it, for example, with concrete. The total number of reinforcing bars 6 (Fig. 2, 3) of the reinforcing cage 5 in the claimed device can be from 6 to 20 (for example, 10 pieces).

The space inside the box - housing 1 (Fig. 2, 3, 5) is intended for the subsequent laying (filling) of tiles (including floor tiles for swimming pools), paving stones, polymer concrete, asphalt, gravel, rubber crumb, artificial turf, and also other coatings, which allows the claimed device to merge with the environment of its location. A concrete screed is laid under the filler. The design of the filling housing 1 of the hatch device (entrance to the underground communication) allows its installation under any canvas, because The options for the design of the filler are limitless, which allows, depending on the specific application, to ensure a uniform appearance, harmony with nature, tightness and smooth operation on streets, sidewalks, pedestrian, bicycle, jogging paths, green surfaces, in swimming pools, workshops, warehouses.

The counterpart 2 (Fig. 1, 2, 7, 8, 9) of the hatch device is inside provided with supporting surfaces 8 (Fig. 2, 7), which are formed by flat areas rigidly fixed to the lower parts of the inner surfaces 9 (Fig. 2, 8 ) vertical walls 10 (Fig. 2) of the counterpart 2 (Figs. 1, 2, 7, 8, 9) along the entire inner perimeter of the counterpart 2 of the hatch in such a way that the counterpart 2 forms a pallet 11 (Fig. 7) of rectangular shape ... The supporting surfaces 8 (Figs. 2, 7) are welded to each other using, for example, semi-automatic welding in a gas atmosphere, welded to the upper edges (not shown in the figure) of the vertical walls 4 (Figs. 1, 2) of the housing 1 (Fig. 2, 3, 5). Plates 17 (Fig. 1, 2, 3) of triangular shape are made of sheet steel. Each of the four plates 17 of a triangular shape has one shaped hole 18 of an oblong shape. Each shaped hole 18 of an oblong shape is made parallel to the hypotenuse of a triangle of each plate 17 of a triangular shape in which it is located.

In the box of the housing 1 (Fig. 2, 3, 5) under each of the four plates 17 (Fig. 1, 2, 3) of a triangular shape, in the region below the figured holes 18 (Fig. 1, 2, 3) of an oblong shape, there is one vertical glass 19 (Fig. 4) of a cylindrical shape. Four glasses 19 of a cylindrical shape are designed to accommodate, for example, T-shaped keys, with the help of which the cover 1 (Fig. 2, 3, 5) of the hatch device is closed and opened. Also glasses 19 (Fig. 4) of cylindrical shape are designed to prevent the ingress of concrete solution into them when filling with filler (for example, pouring concrete mixture) of the box - cover 1 (Fig. 2, 3, 5) of the hatch device. The height of each glass 19 (Fig. 4) of a cylindrical shape is equal to the distance from the lower surface 20 of the plate 17 (Fig. 1, 2, 3) of a triangular shape to the upper surface 7 (Fig. 3, 5) of the bottom 3 (Fig. 2, 4) building 1 (Fig. 2, 3, 5).

To strengthen the fastening of the plates 17 (Fig. 1, 2, 3) of a triangular shape to the vertical walls 4 (Fig. 1, 2) of the body 1 (Fig. 2, 3, 5) and to prevent their deformation when opening the cover (body 1) of the hatch with the use of special means under each plate 17 (Fig. 1, 2, 3) of a triangular shape, a reinforcing element 21 (Fig. 2, 3, 4) is made of reinforcement, which has a curved U-shape. Each of the four reinforcing elements 21 with their two ends is welded by means of semi-automatic welding in a gas atmosphere to the upper surface 7 (Fig. 3, 5) of the bottom 3 (Fig. 2, 4) of the body 1 (Fig. 1, 2, 5, 9) , and the other (upper) end - is welded to the free generatrix 22 (Fig. 3, 4) plate 17 (Fig. 1, 2, 3) of triangular shape.

All structural elements of the hatch device, except for the reinforcing frame 5 (Fig. 2, 3), reinforcing elements 21 (Fig. 2, 3, 4) and brackets 14 (Fig. 2, 7, 8) U-shaped, are made of structural steel, for example, Art. 3 GOST 380-2005. The welded elements of the body 1 (Fig. 2, 3, 5) and the counterpart 2 (Fig. 1, 2, 7, 8, 9), each separately, are coated with a corrosion-resistant coating, for example, a zinc coating in accordance with GOST 9.303-84 with a coating thickness of 9 microns.

Reinforcing frame 5 (Fig. 2, 3) of the body 1 (Fig. 2, 3, 5), reinforcing elements 21 (Fig. 2, 3, 4) plates 17 (Fig. 1, 2, 3) of triangular shape and staples 14 (Fig. 2, 7, 8) U-shaped counterpart 2 (Fig. 1, 2, 7, 8, 9), made of reinforcing steel bars A500C according to GOST 34028-2016.

The proposed technical solution is used as follows. The counterpart 2 (Fig. 1, 2, 7, 8, 9) of the hatch cover - body 1 (Fig. 2, 3, 5) is installed in the soil (ground) above the sewer well so that the upper boundaries of the vertical walls 4 (Fig. 1, 2) of housing 1 (Fig. 2, 3, 5) and vertical walls 10 (Fig. 2) of the counterpart 2 (Fig. 1, 2, 7, 8, 9) of housing 1 (Fig. 2, 3, 5 ) were flush with the surface of the surrounding space - earth (ground), tiles, concrete, etc. Then the hatch cover-housing 1 is placed on the support surfaces 8 (Fig. 2, 7) of the counterpart 2 (Fig. 1, 2, 7, 8, 9). The inner space of the box - cover 1 (Fig. 2, 3, 5) is filled with filler - concrete, tiles, asphalt, etc. The space outside the vertical walls 10 (Fig. 1) of the counterpart 2 (Figs. 1, 2, 7, 8, 9) is filled with concrete, tiles, asphalt, etc. The type of filler depends on the type of its environment, which allows the proposed hatch device to merge with the environment. Through the shaped holes 18 (Fig. 1, 2, 3) of the oblong shape of the plates 17 having a triangular shape, the hatch cover - body 1 (Fig. 2, 3, 5) is lifted using, for example, T-shaped keys (in Fig. not shown). When using a hatch device on sidewalks and footpaths, the best option is to install it, in which two parallel sides of the structure are parallel to the direction of movement of communal cleaning equipment. The proposed hatch device is capable of withstanding loads of up to 15 tons.

In the proposed technical solution, the presence above four cylindrical glasses of four triangular plates with shaped oblong holes for opening the hatch allows the glasses to be protected from filling them with filler. The location of these glasses and plates with shaped holes of an oblong shape in the four corners of the body also protects the glasses from direct ingress of a cement mixture into it, which increases the operational capabilities of the proposed hatch device, in contrast to the prototype, where there are only two cylindrical glasses, which are located in the center of the body and do not have protective plates, as a result of which there is a high probability of filling the filler into two glasses, which are located in the center of the box. Also, the presence of only two glasses in the prototype leads to difficulty in servicing the hatch, because a heavy suite with filler should be lifted by only one user, while the weight of the hatch filled with filler may exceed the maximum load on the human body.

Unlike the prototype, where there are two stiffening ribs of small thickness and small height, located in the housing box and unable to ensure its strength under the influence of external pressure (loads), in the proposed technical solution, two body stiffeners are made of corners that are welded to the bottom the surface of the bottom of the case, which increases the strength of the case when it is exposed to external (direct vertical and lateral) pressure.

In the proposed technical solution, the presence of a U-shaped reinforcing element located under each of the triangular plates, welded to its freely forming one end, and two other ends welded to the upper surface of the body bottom, strengthens each plate and the bottom of the body from bending, in together, increasing the operational capabilities of the body by strengthening its structure. Thus, the body is not able to bend under the influence of external pressure.

Unlike the prototype, where the counterpart of the body is equipped with four massive reciprocal tides, which increases the dimensions, material consumption and cost of the device, in the proposed technical solution, the outer opposite vertical walls of the pallet are equipped with U-shaped brackets fixed to them, which makes it possible to reduce the consumption of materials and the cost of the claimed devices. The presence of four U-shaped brackets makes it easy to dismantle the hatch device if necessary, which increases the operational capabilities of the proposed technical solution.

In the prototype, the upper part of the body around the perimeter is made of stainless steel, and the lower part of the body is made of carbon steel or other types of steel, which leads to corrosion of the lower part of the body, because it is exposed to humid air, for example, from the opening of a sewer well, which reduces the performance of the prototype. In the proposed technical solution, all structural elements of the device are made of structural steel - St.3 with subsequent zinc coating, which increases the operational properties of the hatch device, tk. the zinc coating does not corrode during the operation of the product.

All the components of the claimed technical solution are connected (fixed) to each other by assembly operations, i.e. are in functional and constructive unity, which ensures the achievement of the claimed technical result for solving the problem.

The proposed technical solution, which has a constructive unity, implements a common functional purpose (functional unity).

Implementation of the proposed utility model allows solving the claimed technical problem and ensuring the achievement of the claimed technical result.

The prior art has not found an analogue characterized by features identical to all essential features of the claimed utility model.

The applicant tested the proposed device, which confirmed the purpose, feasibility and operability, in connection with which the claimed utility model meets the condition of patentability "industrial applicability".
