Description

The invention relates to the field of construction, namely, to translucent structures that provide explosion safety of the room where this design is installed, by relieving excess pressure from the room during an explosion.

An explosion-proof window is known that contains a main frame and a resettable (hinged) frame that is held onto the main one by means of safety elements, each of which includes a permanent magnet and an inductor with a core made of ferromagnetic material (RU 97762 U1, 09/20/2010). In case of excess pressure inside the room, the signal from the pressure sensor is transmitted to the inductor, and a magnetic field appears in the core, which pushes the field of the permanent magnet and pushes the frame or section of the frame.

Known easy-to-reset window construction, which contains a frame installed in the mounting opening using destructible fasteners (RU 182927 U1, 09/06/2018). With increasing pressure inside the room, the attachment points are destroyed, and the frame is thrown out of the mounting opening.

Closest to the proposed one is a window structure containing a frame opening inside the room (the first leaf), hinged to the box, looped to the frame, the inner (second) leaf opening outward for discharge of combustion products into the atmosphere during the explosion, a locking mechanism fixing the inner leaf , an element in the form of a membrane that responds to an increase in pressure indoors, is rigidly connected with the locking mechanism, and an elastic mechanism for opening the inner sash during an explosion in the form of rsion, consisting of a package of plates of high-strength steel, the rods of which are simultaneously fixing fingers for hinges of the inner casement, one end of the package is rigidly fixed in a steel holder mounted in the frame of the window structure, and the other end is fixed in a sleeve mounted in the opening inner casement of the window casement design, and acts as a hinge (RU 2301312 C2, 06/20/2007).

A disadvantage of the known construction is that the torsion bars used as a mechanism for opening the inner casement create an additional dynamic effect on the inner casement and can destroy the casement material, as well as the need for an additional device to control overpressure, which significantly complicates and increases the cost of the window . In addition, this design cannot be integrated used in modern standard windows used in mass construction.

The technical task of the invention is to create a simple design that ensures the explosion safety of the room without destroying the sash and is applicable to windows of the standard design currently used in mass construction.

The technical problem is solved by a translucent structure according to the first embodiment, containing a frame on which the first hinge group is mounted on the side of the room, to which the first sash is connected, opening to the inside of the room, the second hinge group is installed on the first sash on the outside, by means of which a second hinge is attached to the first sash the sash opening outward, while on the second sash there are fittings with trunnions, and on the first sash there are reciprocal strips, the thickness of which is selected from the condition their destruction with increasing pressure indoors.

In a preferred embodiment, the frame is made of a L-shaped profile, the first sash is made of a T-shaped profile and the second sash is made of a T-shaped or Z-shaped profile, and each hinge group is mounted at the end of the rack of the corresponding profile.

The technical problem is solved by the translucent construction according to the second embodiment, comprising a frame with at least one impost, the first hinge group is installed on the frame or impost from the side of the room, to which the first sash is opened, opening to the inside of the room, the second hinge group is installed on the first sash from the outside by means of which a second leaflet is attached to the first leaflet, which opens outward, while the fittings with trunnions are located on the second leaflet, and the reciprocal strips are located on the first leaflet, then ness which ensures their destruction when the pressure inside the room.

In a preferred embodiment, the frame is made of a L-shaped profile, the impost is made of a T-shaped profile, the first sash is made of a T-shaped profile and the second sash is made of a T-shaped or Z-shaped profile.

In this case, each loop group can be located at the end of the rack of the corresponding profile, or the second loop group is located between the profiles of the first and second racks.

The technical result achieved by the invention is to simplify the design by eliminating the need to use a special mechanism for opening the inner flap and a device for controlling pressure.

The invention is illustrated by drawings.

In FIG. 8 - the proposed translucent structure according to the second embodiment with an impost with a second inner casement of a Z-shaped profile, in the closed position.

In FIG. 9 - the proposed translucent structure according to the first embodiment with loop groups located on different sides relative to the translucent element in the closed position.

In FIG. 10 - trunnion of fittings of the second inner sash and the strike plate of the first sash.

The proposed translucent structure can be made in the form of a window, door, sliding structure, etc. from a PVC profile, fiberglass, wood, aluminum, as well as their combinations or other materials.

The translucent structure of the first embodiment shown in FIG. 1, comprises a frame 1 (box) of an L-shaped profile, on which, from the side of the room (in the drawing below), a first hinge group 2 is installed, by means of which a first leaf 3 of a T-shaped profile is attached to the frame 1, which opens into the room.

A second hinge group 4 is installed on the first leaf 3 from the outside (in the drawing above), by means of which a second inner leaf 5 of a T-shaped profile is attached to the first leaf 3, which opens outward. The drawings show that the loopback groups 2 and 4 are located at the ends of the uprights of the profiles of the wings 3, 5. However, the loopback group 4 can be hidden, that is, located in the inner space between the wings 3 and 5.

In the casement 3, a translucent element 6 is installed - a double-glazed window, glass, a sandwich panel, etc.), which is held by a glazing bead 7 mounted on the casement 5 from the inside.

In both variants of the invention, loop groups 2 and 4 can be located both on one side of the translucent element 6 (Fig. 1-8), and on different sides relative to the translucent element (Fig. 9).

A possible embodiment (Fig. 5-8), when the second inner sash 8 is made of a Z-shaped profile. Then the glazing bead 6 is installed on the outside of the sash 8.

On the side opposite to the position of the loopback groups 2 and 4, the handles 3 and 5 are equipped with handles 9 and 10, respectively. The handle 10 is removable and provides locking of the second inner casement 5 (8) relative to the first casement 3.

In the translucent structure according to the second embodiment, the frame 1 may have an impost 11 (Fig. 4, 8), between which and the frame 1 a second translucent element is fixed. In this case, the first loop group 2 can be located both on the frame 1 itself and on the impost 11, as shown in FIG. 5, 8. An embodiment is also possible when the frame 1 has a second impost on the other side of the wings 3 and 5 (8) (not shown in the drawings). In this case, the translucent element may also be located between the imposts. In this embodiment, as in the first, loop groups 2 and 4 can be located at the ends of the racks of the profiles of the wings 3, 5 (8), as shown in FIG. 5. Either loop group 4 can be hidden, that is, located in the inner space between wings 3 and 5 (8).

In the proposed translucent structure, as well as in standard structures used in mass construction, on the first sash 3 there are fittings on the outside, and on the frame 1 or impost 11 there are response strips (not shown in the drawings) which, when engaged with the trunnions of the fittings, provide locking the sash 3 relative to the frame 1 around the perimeter.

In addition, in the proposed design, on the second inner casement 5 (8), fittings 12 are located outside (shown in Fig. 10), and reciprocal strips 13 are located on the inside of the first casement 3, which, when engaged with the pins 14 of the fittings 12, provide locking leaf 5 (8) relative to leaf 3 around the perimeter. The thickness of the strips 13 is determined by the results of bench tests in such a way that the explosion breaks the strips 13 and the second inner casement 5 (8) opens. The required thickness of the mating slats 13 is provided in the manufacture of special mating slats or when milling existing standard slats.

The proposed translucent design works as follows.

The design is made in the form of a complex (combined) combination - “sash in sash”. Due to this, the design can be opened both inside the room (the main type of opening) and outside (type of opening to relieve pressure)

In FIG. 1, 4, 5, 8, and 9 show the closed position of the translucent structure. In this position, tight closure is ensured, as in the normal mode, it is “closed” of any translucent structure. This mode is set using knob 9.

In FIG. 2, 6 show the main type of opening when the sash 3, together with the T-shaped sash 5 or the Z-shaped sash 8, opens into the room. In this case, any type of opening is possible - tilt-swivel, swivel, sliding. The type of opening will depend on the installed hardware. This mode is set using knob 9.

In FIG. 3, 7, the option of opening the T-shaped second leaf 5 or Z-shaped second leaf 8 outward when excessive pressure occurs indoors. Opening occurs automatically when there is an excess of pressure inside the room, for example, when a gas explosion occurs or for another reason, due to the use of fittings on the second inner casement 5 (8) in combination with mating strips 13 on the first casement 3, which break with pins 14 at a certain load. Thereby, the effect of automatically opening the sash 5 (8) and the relief of excess pressure from the room are achieved. It also provides easy exit from the premises in case of emergency.

The advantages of the proposed translucent design are as follows.

1. In the event of an explosion, the second inner casement 5 (8), which opens outward, remains engaged with the main structure (hinge group 4), and does not fly out of the opening, as occurs in easily ejected structures.

2. It is possible to install any filling in a translucent construction of a double-glazed window, glass, sandwich panel, etc.), and it does not require the installation of glass, which should break due to excess pressure, for example, tempered glass.

3. No special pressure sensors, spring mechanisms, etc., are required, as is the case in the design of RU 2301312, since the emergency opening mechanism - fittings and reciprocal slats - is an integral part of the leaf structure and does not depend on external factors (for example, the absence of power supply of any sensor).

4. It is possible to mount the structure (window) in a quarter of the wall opening in accordance with GOST. This allows you to use the design for residential premises, creating a high level of comfort and tightness of the room.

5. The main type of opening the sash 3 inside the room helps to increase heat and sound insulation, the implementation of the ventilation function, provides the necessary level of protection, as well as ease of use and comfort.
