Description

The technical solution relates to the field of construction, namely to easy-reset window constructions used in explosive facilities.

From the prior art, the invention is known as the "window structure and its elements" according to US patent US 6216401, publ. 04/17/2001, containing:

Profile sections of the frame, including:

- the main element installed between the profiled sections, designed to accommodate and support the corresponding end of the glass;

- a stiffener designed to support the end of the glass and transmit explosive pressure in the event of its impact on the glass to the main element;

- a damping device made in the form of a zigzag, flexible metal strip, designed to extinguish explosive energy acting on the glass;

- gaskets with curly protrusions;

- figured grooves for sealants;

- glass.

Common features of the characterized invention and the proposed technical solution are:

- profiled frame;

- gaskets with curly protrusions;

- figured grooves for sealants;

- glass;

The disadvantage of the described invention is that this invention is not able to provide the dropping of glass when exposed to a blast wave, as a result of which overpressure, for example, a load of 70 kilograms per square meter formed in the room, will destroy the entire window structure and damage the load-bearing walls on which it has been fixed. The damping device is not able to withstand destruction from a blast wave.

Also, from the prior art there is known a technical solution according to the patent of the Russian Federation No. 63403 for the utility model "Easy-reset window construction", containing:

- window unit with frame;

- double-glazed window;

- gaskets;

- supporting elements;

- stud bolts equipped with destructible elements that are mounted on the stud bolts mentioned above by means of spacer sleeves;

- fasteners, including basic elements connected with the window block, made in the form of brackets;

- spacers made with an annular protrusion of material that does not form sparks when impacting with steel, and installed with the possibility of eliminating the occurrence of contact of self-tapping pins and base brackets;

- a frame with a double-glazed window, installed in the window unit using the above-mentioned fastening nodes.

Common features of the above utility model and the proposed technical solutions are:

- profile frame construction;

- glass;

- gaskets;

- fastening elements of the profile frame to the frame (in the case of the proposed technical solution, this is a crossbar from the profile).

The technical essence of the described technical solution lies in the fact that it allows for the removal (easily erasable) of window openings of plastic and aluminum frame window blocks glazed with single and double chamber glass units, since at elevated pressure, for example, up to 70 kilograms per square meter in the room, it is destructible the element of the fastener assembly fails, thereby freeing the self-tapping screw from communication with the base element of the fastener, and thereby excludes the fastening of the frame window unit with glass mounted in the wall panel, by fixing the base member - angled metal sheets. With increased pressure, the fluoroplastic disk (destructible element) is destroyed, and thereby the attachment point loses additional fixation and collapses, and the window structure flies out.

The disadvantage of the described utility model is that when the blast wave is destroyed, the entire frame window unit with a double-glazed window is destroyed, the wall openings to which the structure is fixed are damaged, resulting in labor costs for the restoration of the entire window structure, wall openings, which generally confirms the inefficiency of such a design . As tests show, the main load during the blast wave primarily affects the glass, and if there is no quick extrusion (discharge) of glass due to its delay by some elements, then to overcome the obstacle the blast wave can destroy the entire window structure, including including damage to the supporting structures of the building, responsible for the strength and safety of the structure. Therefore, the effectiveness of easy-to-clean window structures depends to the greatest extent on how quickly the glazing is removed, as a result of which the reduction of excess pressure arising from internal explosions at objects will occur faster.

From the existing level of technology is also known easy-to-remove design without opening elements SIAL KP50, selected as the closest analogue (prototype) and containing:

- profile frame;

- glass;

- gaskets;

- grooves for sealants;

- an additional element, made in the form of a figured profile with a groove at its corresponding end, for fixing the protrusion of the seal into it, and with a protrusion at its other end for fixing into the corresponding groove, made in the profile frame, while the additional element has a branch section, parallel to adjacent to the corresponding surface area of the glass;

- a corner, one section of which is attached to the crossbar, and the other parallel to the branch section of the additional element adjoins the glass;

- adhesive tape or butyl connecting self-adhesive tape located between the corner surface parallel to each other and the glass surface;

- a clamping level with a decorative cover;

- figured core;

- figured recess, made in the profile frame for entering into it a shaped rod with the possibility of extraction;

Common features of the prototype described above and the proposed technical solution are:

- profile frame;

- glass;

- gaskets;

- grooves for sealants;

- a clamping level with a decorative cover;

- shaped rod included in its corresponding figured recess, made in the profile frame;

The disadvantage of the described prototype is the low discharge characteristics of the window construction elements.

This is primarily due to the fact that the glass is glued by means of adhesive tape or butyl connecting adhesive tape to the corresponding section of the corner, which is parallel to the surface of the glass to which it is attached, fixed to the crossbar. As practice shows, during operation, in particular at temperature extremes, glass is very reliable, due to the adhesive properties of the connecting adhesive tape, adheres to the specified corner, which requires considerable force to detach it from the surface of the specified corner. In the event that the glass does not detach from the corner, then when extruding, the glass will pull the corner attached to the crossbar while extruding, resulting in damage to the crossbar. Another disadvantage of the prototype is the configuration of the additional element, made in the form of a shaped profile, which is located at one of its ends, having a protrusion, in the corresponding groove of the profile frame, and its other end, having a groove, is engaged with the protrusion of the seal, while the branched section of the additional element parallel to the corresponding surface area of the glass. When the pressure of the glass on the branch section of the additional element, which is adjacent to the corresponding surface of the glass, additional effort is required to remove the end of the additional element having a protrusion from its corresponding groove in the profile frame. Thus, for the implementation of the rapid discharge of glasses in the specified technical solution, it is necessary to overcome two additional forces, and the elements that delay the discharge of glasses can cause the collapse of the strut and the subsequent destruction of the supporting elements.

The technical result of the proposed technical solution is to increase the speed of discharge of structural elements at an overpressure of a blast wave.

The technical result is achieved due to the fact that the easy-to-clean window construction contains a profile frame, including a first distance frame, a first seal, which engages with its figured protrusion with the first figured groove made on the corresponding walls of the profile frame, the first glass located between the corresponding outer surface of the first the seal and the corresponding outer surface of the first distance frame, the second seal, which engages with its figured protrusion about the second shaped groove made on the corresponding walls of the profile frame adjacent its corresponding outer side to the corresponding external side of the second distance frame, a shaped rod included in its corresponding figured recess made in the profile frame between the first and second distance frames, made with the possibility of extraction from a figured recess and connected by a fastener through a through hole made in the corresponding section of the clamping plate, wife on the corresponding section of the outer surface of the profile frame having a first shaped groove engaged with the protrusions of the third seal adjacent its corresponding outer surface to the corresponding external surface of the profile housing, a second shaped groove engaged with the protrusions of the fourth seal adjacent its corresponding external surface to the corresponding outer surface of the second glass adjacent its other outer surface to the corresponding outside It surfaces of the first spacer.

For clarity, we give a breakdown of some terms used to characterize the proposed technical solution:

- gaskets are elastic gaskets of a tubular or more complex shape, running along the perimeter of the window, protecting against the penetration of cold air, noise and moisture;

- the first distance frame - the frame that holds the glass at a distance (distance) between each other;

- the second distance frame is the frame that forms the necessary distance (space, distance) inside the profile frame, through which the frame is connected to the crossbar.

The implementation of the proposed technical solution with a remote frame, which is mainly made of plastic, for example, by injection molding of melt using prefabricated molds, and without any shaped protrusions and grooves on its surfaces, is necessary for the formation of the technologically necessary space between first and second and second glass, as well as to facilitate the rapid loss of glass at high pressure.

Under normal loads, the first distance frame is sandwiched between the first and second glass, as a result of which it cannot fall out, while between the surfaces of the first distance frame and the surface of the glasses, as well as its surface adjacent to the corresponding wall of the figured groove intended to enter the figured the rod, there is no adhesive material or self-adhesive connecting tapes, and there are no protrusions and grooves that interlock them and interfere with its free falling out of the structure when increased pressure on the glass.

A figured rod included in its corresponding figured recess, and its execution with the possibility of extraction from the figured recess made in the profile frame between the first and second distance frames, and the connection of the figured rod with the pressure bar through a through hole made on the corresponding section of the pressure bar, which through the fourth sealant holds the second glass, separated from the first glass by the first distance frame, provides power at an overpressure of the blast wave, For example, more than 70 kilograms per square meter, squeezing the first and second glasses that are outwardly as a result of movement, act on the clamping plate, which is connected through a through-hole with a shaped rod located in the corresponding shape and size figure recess in the profile frame. Removing the clamping strip entails removing the curly rod from the corresponding recess in the profile frame. Thus, the entire window structure is released from the glass, as a result of which the excess pressure in the room is reduced, and the remaining structural elements of the window structure and the supporting structures of the building responsible for safety and stability remain intact. At the same time, to ensure the necessary strength, under normal loads on the glass, a fastening element, for example, a self-tapping screw connecting the clamping bar to the figured rod, is made with the possibility of entering the body of the figured rod and has a groove at its corresponding end for screwing it, for example , a screwdriver, into the body of a curly rod. The shaped rod can be made, for example, hollow and of plastic material, for example, by injection molding using prefabricated molds. The clamping bar can be made of any known material, for example plastic, for example, by the known method of injection molding of melt using prefabricated molds. When the fastening element is twisted, for example, to the right side, depending on the direction of the thread, the figured rod expands towards the inner walls of the figured recess, which ensures the necessary strength of fixing the figured rod in the figured recess. When the specified fastening element is loosened in the opposite direction, the figured rod is weakened with respect to the inner walls of the figured recess, as a result of which it can be freer removed from the figured recess. To ensure the operation of the easy-to-reset window structure in various operating conditions, the density of fastening of the figured rod in the figured recess necessary for these purposes is chosen. The profile frame can be made, for example, of any material that meets the necessary strength characteristics for these purposes, for example, aluminum, for example, by injection molding using prefabricated molds. As glass, for example, glass that has not undergone heat treatment (unhardened, non-heat-strengthened, not laminated with film, unreinforced) can be used. Sealers can be made of any material that meets their functional purpose, for example, rubber. The second distance frame is made of any known material, for example, aluminum, for example, by injection molding using prefabricated molds. The proposed easy-to-reset window construction is attached to the crossbar by means of a fastening element, for example, a bolt passing through the corresponding through holes made in the second distance frame. The crossbar is attached to the building opening due to fasteners, for example, bolts.
