Description

Technology area

This utility model relates to the field of construction, in particular, to the attachment points for easily disposable enclosing structures in explosive areas to reduce the consequences of a deflagration explosion.

State of the art

Over the past few years, an increasing number of cases of domestic gas explosions in private and multi-storey buildings have been recorded. Also, every year the number of enterprises with explosive industries is increasing. This is due to both the reconstruction of old production facilities and the construction of new ones. Now the owners of explosive rooms are increasingly faced with the issues of ensuring explosion safety and, as a solution, timely reduction of excess pressure during a deflagration explosion.

The room, in which there is a risk of accumulation of explosive mixtures, must be equipped with explosion-proof structures that protect the walls from collapse and the negative impact of excessive pressure on people. In order for the pressure in the room not to exceed the critical level and not to destroy the building, it must somehow decrease to the maximum permissible values. Overpressure can be relieved by means of easily dumped enclosing structures, during the installation of which a real attachment point is used.

The known design of the attachment point for the hinged facade (Patent RU 8722 dated 03.19.1998), where the attachment point is an intermediate element, clamp and fasteners of the facade. The intermediate element is made in the form of a plate and is fixed on the frame of the building, and the clamp is made of two corners rigidly connected to each other, while the fastening elements of the facade and the intermediate element are placed in elongated grooves, and the clamp is rigidly attached to the intermediate element and the plate, the width of which is not greater than the distance from the edge of the plate to the holes.

The disadvantage of this design is the absence of a collapsing element attachment point in the clamp, which would ensure the easy release of the facade structure and the release of the excess explosion pressure.

Known "Easy-release enclosing structure" (patent RU 159944 from 03.08.2015), where the easily-release enclosing structure consists of double-glazed windows with supporting elements and attachment points for double-glazed windows on the building. Double-glazed windows are fixed outside the building frame with screws and washers, on a metal profile, with the depth of the screws and with a pitch selected from the condition of ensuring the overpressure value is not more than 200 kg / m2 and the force to pull out the screws with washers. The metal profile at the points of fastening of glass units with screws and washers is equipped with sockets for screws with a depth corresponding to the depth of installation of the screws. The structure is equipped with a rubber seal installed between the metal profile and the glass units.

The disadvantage of this design is to ensure sufficient tightness of the external (street) contour of glass units from atmospheric precipitation, since the washers are installed pointwise, which will lead to water leakage into the internal cavities of the structure, followed by leakage into the room. Also, a disadvantage of the design is that the device of this design does not ensure the retention in the opening of the building of its constituent parts flying out during an explosion, which can cause harm to human health and damage to property.

Known "Easy-release window structure" (patent RU 190978 dated 05/21/2019), containing a profile frame, including the first seal, which comes in its figured protrusion into engagement with the first figured groove made on the corresponding walls of the profile frame, the first spacer profile included with its figured protrusion into the second figured groove made on the corresponding walls of the profile frame, the second spacer profile engaging with its figured protrusion with the third figured groove made on the corresponding walls of the profile frame, the first figured rod entering the corresponding figured recess made in the second spacer profile and a profile frame, a glass unit located between the corresponding outer surface of the first sealant and the corresponding outer surface of the second sealant, which engages with its shaped protrusion with the fourth shaped groove made on the corresponding walls by pressing the th strip adjacent to the corresponding outer side of the first spacer profile, the third seal engaging with its shaped protrusion with the fifth shaped groove made on the corresponding walls of the clamping strip, the second shaped rod entering through the through holes made in the corresponding section of the clamping strip and in the first spacer profile, and entering with its protrusion into the corresponding second shaped groove, made with the possibility of being removed from the second shaped groove, characterized in that it contains a fourth seal with a shaped protrusion, the second spacer profile contains a sixth shaped groove made on the corresponding walls, while the figured protrusion of the fourth sealant engages with the sixth figured groove of the second spacer profile, the other side of the fourth sealant adjoins the corresponding side of the third sealant, a sealant is fixed on the outer surface of the glass unit and on the first spacer profile streaming tape.

The disadvantage of this design is the complexity of the selection of the first curly rods for the pulling out load, since in an easily resettable design, glass units of different areas can be installed and, accordingly, the rods for each glass unit must be individual in terms of load. Also, a disadvantage of the design is that the device of this design does not ensure the retention in the opening of the building of its constituent parts flying out during an explosion, which can cause harm to human health and damage to property.

The device disclosed in patent RU 190978 is taken as a prototype.

Disclosure of the essence of the utility model

This utility model is based on the technical problem of creating a universal attachment point for an easily releaseable facade structure, which allows maintaining the integrity of the mounting opening, as well as the structure itself, with timely release from the overpressure of the explosion.

The technical result of using the proposed utility model is to simplify the design, ensure its versatility and facilitate installation.

The technical result is achieved by the fact that the attachment point of an easily resettable structure consists of a bracket in the form of a U-shaped profile intended for attachment to the mounting opening and an embedded part intended for attachment to a front easily resettable structure, characterized in that the bracket and the embedded part are fastened with a bushing and an element that is destroyed by the action of excess pressure on an easily release structure in the event of an explosion.

In particular, all parts of the attachment unit are made of materials with a higher strength than a destructible element.

In particular, the bracket can be represented in the form of two oppositely directed corners united by a plate, in which grooves for supporting elements are provided.

In particular, the bracket and the post of the façade structure are connected by a safety cable.

In particular, the collapsing element is represented by an axis in which weakened points in the form of grooves are provided.

Physical parameters, in particular, strength characteristics (groove depth), dimensions, collapsing axle material are selected depending on the expected loads.

In particular, the collapsing axle is held in the bracket by means of fasteners. Such elements can be represented, for example, by cotter pins, retaining rings, nuts.

In particular, the profile of the embedded part of the rack can be represented by various sections, which are selected according to the catalogs of manufacturers of hinged facade systems.

Implementation of the utility model

FIG. 1 shows the attachment point of an easily resettable structure in accordance with the present utility model. The attachment point of an easily resettable structure consists of a bracket in the form of a U-shaped profile 1 ', intended for attachment to the mounting opening and a fixing part 9 of the post 2 of the facade structure, which are fastened with a bushing 3 and, inserted into it, a destructible element 4, which is fixed when using the fastening element 5, for example, a cotter pin in the grooves of the bracket 1 '. The embedded part 9 performs an adjustment (orientation of the frame of the facade structure horizontally), support and, together with sleeve 3, a shearing function (transfer of the load from the explosion pressure acting on the facade structure through sleeve 3 to the destructible element 4). In this case, the bracket 1 'can be additionally connected to the post 2 with a safety cable 6. The safety cable 6, in turn, can be connected to the bracket 1' and the post 2 by means of a bolt connection 7 and plate 8. The cable 6 can be fixed to the plate 8 and bracket 1 'using carabiners (not shown in the figure). Rope 6 allows you to prevent excessive, unsafe overhang of an easily dumped facade structure in the event of an explosion, as well as to preserve its integrity.

FIG. 2 shows a variant of the attachment point of an easily resettable structure in accordance with the present utility model. The attachment point of an easily resettable structure consists of a bracket 1 '', consisting of two multidirectional corners, united by a plate, intended for attachment to the mounting opening and the post 2 of the facade structure, which are fastened with a destructible element 4, which is fixed using a fastening element 5, for example, cotter pin in the grooves of the bracket 1 ''. The supporting element, consisting of a bushing 12 and a bolted connection 10, is designed to hold the easily resettable structure in weight and is inserted into the open groove 11 of the bracket 1 ''. In this case, the bracket 1 '' can be additionally connected to the post 2 with a safety cable 6. The safety cable 6, in turn, can be connected to the bracket 1 '' and the post 2 by means of a bolted connection 7 and plate 8. The cable 6 can be fixed to plate 8 and bracket 1 '' using carabiners (not shown in the figure). Rope 6 allows you to prevent excessive, unsafe overhang of an easily dumped facade structure in the event of an explosion, as well as to preserve its integrity.

The destructible element consists of a material that is less durable than all elements of the attachment point of an easily releaseable structure, for example, from a fluoroplastic, and can be made in the form of any configuration of a three-dimensional model, the physical parameters of which are selected depending on the expected loads.

Let us consider an example of mounting an attachment point for an easily resettable structure in accordance with this utility model. In this example, the easy-release structure is the mullion-transom façade structure. It should be noted that this attachment point for an easily resettable facade structure is universal and can be installed on post-transom facade systems of various manufacturers. The assembly of the attachment point can be carried out by an installer directly at the construction site, or preliminarily at the factory.

Each assembled easily resettable structure should be supplied with a diagram of the fastening of the destructible nodes, on which the places of their fastening are indicated in accordance with their marking (pre-calculated load of destruction). Each post of the facade structure is attached from above and below to the opening with the help of destructible attachment points.

FIG. 3, the assembly of the attachment point for an easily resettable facade structure is as follows: in the opening from above and below, the places for installing the brackets in the form of an u-shaped profile 1 'are marked in accordance with the step of the posts 2 of the facade structure. Brackets 1 'are fixed to the opening using fasteners (anchors, self-tapping screws). An embedded part 9 is inserted into each post from above and from the bottom of the facade structure, with a pre-drilled hole into which the sleeve 3 is inserted. Each post of the facade structure is oriented between the upper and lower brackets in the opening by means of embedded parts 9 in accordance with the mounting clearances. Embedded parts 9 are fixed to the uprights with 2 self-tapping screws (or other typical fastening according to the catalog of the manufacturer of post-transom facade structures). The bushing 3 is oriented coaxially with the groove in the bracket 1 ', into which the destructible element 4 is inserted in the form of an axis and is fixed on both sides with cotter pins 5. Thus, the bracket 1', the bushing 3 and the embedded part 9 are combined into a single destructible attachment unit. This stage of installation is repeated alternately with all the posts of the facade post-transom structure. After mounting the post-transom frame of an easily resettable structure, a safety cable 6 is mounted to each post using a bolted connection 7, plate 8 and carabiners (not shown in the figure). Further assembly, installation of fillings (double-glazed windows) of an easily resettable structure is carried out according to the traditional technology according to the catalogs of manufacturers of facade systems, with the exception that the abutments (flashing, ebb) are attached only to the frame of the easily resettable structure. Upon completion of installation, a warning sticker is glued to the easily releaseable structure, with information that this window is an easily releaseable structure, and any over-rated pressure can destroy it.

Thus, the use of this utility model makes it possible to simplify the labor intensity of the installation of easily resettable post-transom facade structures by adjusting the mounting clearances by means of embedded parts, which are traditionally used in the installation of conventional, non-easily resettable facade structures of many manufacturers. The assembled easy-to-flush structure meets operational characteristics such as tightness, heat-efficiency, aesthetics on a par with conventional non-easily-flush facade structures. At the same time, the structural elements used in the device, such as a cable, provide a safe discharge of structures without harm to others, which makes it possible to use it both in industrial and residential buildings.
