Description

Technical field

This utility model relates to the field of construction, in particular, to the attachment points of easily erasable enclosing structures in explosive rooms to reduce the effects of a deflagration explosion.

State of the art

Over the past few years, an increasing number of cases of explosion of domestic gas in private and high-rise buildings have been recorded. Also, every year the number of enterprises with explosive industries is increasing. This is due to the reconstruction of old industries, and the construction of new ones. Now the owners of explosion hazardous premises are increasingly faced with questions of ensuring explosion safety and, as a solution, timely reduction of overpressure in a deflagration explosion.

The room, in which there is a risk of the accumulation of explosive mixtures, must be equipped with explosion-proof structures that protect the walls from collapse and the negative effects 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 be reduced to the maximum permissible values. Overpressure can be relieved by means of easily erasable enclosing structures, the installation of which uses this mount.

A well-known common design of the anchor plate (Patent RU 137918 from 07/30/2013), where the anchor plate is a part obtained from sheet metal, which has holes for attaching it to wall openings or to supporting building structures, and a curved element, wherein the anchor plate contains along the entire length on both sides there are bent edges to give rigidity to 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 lack of a collapsing element in the plate, which would ensure the release of excess pressure, preventing an explosion, as well as its unregulated length, which can complicate installation.

The well-known “Easily erasable building envelope for explosive rooms”, patent RU 177097 dated 10/05/2017, where the easily erasable building envelope consists of a support bracket connected to a building using a power frame and a displaceable element attached from the inside of the room to the support bracket using a screw that passes through the hole in the support bracket, through a distance washer installed in the hole in the bracket with a gap, and through the collapsible washer to oruyu screw presses its head to the support bracket.

The disadvantage of this design is the complexity of installation and manufacture: not all fixtures can fit this fastener. The mounting seam can have significant deviations, irregularities, in this regard, for each individual window, careful measurements are required and the support brackets of different heights are made, which entails additional labor and time costs.

Known "Easily erasable design based on a window unit made of aluminum alloy", patent RU 164517 dated 04/22/2016, relating to erasable structures used at excess pressure, which is created as a result of accidents, and can be used to fasten structures of window blocks of aluminum alloy in explosive areas. To increase the reliability of the structure at normal pressure, improve performance and operational safety, the reliability of the structure itself as a whole, at various wind loads, which entail changes that cause destruction of the fasteners, it contains supporting elements, basic elements, destructible fasteners, including fastening elements, spacer sleeves with destructible elements mounted on them, as well as at least two safety devices, each of which which is made in the form of a galvanized steel cable fixed at one end in the mounting wall opening of an easily erasable structure, and with the second end fixed to the frame of an easily erased window structure using a bracket and fasteners, the spacer sleeves of destructible fasteners being installed with the possibility of eliminating the contact of basic elements and fastening elements made in the form of studs, each of which is rigidly fixed at one end to the frame by means of a rivet nut, and the second the end is rigidly connected to the destructible element, equipped with a spring clip and a protective cap.

The disadvantage is the complexity of the design, the complexity of installation and manufacture: not all fasteners can fit this fastener, as well as a galvanized steel cable, the presence of which adversely affects the thermal characteristics: freezing of the mounting joint of an easily ejected design.

You can also add to the disadvantages that both patents RU 164517 and RU 177097 are unaesthetic, bulky and have direct access to collapsing elements.

The device disclosed in patent RU 177097 is taken as a prototype.

Utility Model Disclosure

The present utility model is based on the technical task of creating a universal fastener for an easy-to-clean design that allows you to maintain the integrity of the mounting opening, as well as the design itself with timely release from excess pressure.

The technical result from the use of the proposed utility model is to simplify the design, ensure its versatility and ease of installation.

The technical result is achieved by the fact that the fastener assembly of the easy-to-erase structure consists of two plates, one of which is intended for fastening to the easy-to-erase structure, and the other is intended for fastening to the mounting opening, and are fastened using an element that collapses from excess pressure on the easy-to-erase structure.

In particular, both plates are made of a material with a strength higher than the collapsing element.

In particular, a plate intended for attachment to an easy-to-erase structure is made of several tear-off segments, each of which contains an opening for fixing a collapsing element.

In particular, the plates are connected by a safety cable.

In particular, the collapsing element is represented by a collapsing sleeve.

Physical parameters, in particular, strength characteristics, dimensions, weight of the collapsing sleeve are selected depending on the expected loads.

In particular, the collapsing element is represented by a collapsing plate.

In particular, the collapsing plate has divisions for several expected loads with notch recesses.

Brief Description of the Drawings

The essence of this utility model is illustrated with reference to the drawings, in which:

- in FIG. 1 shows a fastener assembly of an easily erasable structure with a collapsing member represented by a collapsing sleeve;

- in FIG. 2 shows a fastener assembly of an easily erasable structure with a collapsing member represented by a collapsing plate;

- in FIG. Figure 3 shows the assembly of an easily resettable window structure.

Utility Model Implementation

In FIG. 1 shows a fastener assembly of an easily erasable structure in accordance with this utility model. An attachment unit of an easily erasable structure consists of a segmented adjustable plate 1 intended for attachment to an easily erasable structure, of a plate 2 intended for attachment to a mounting opening, interconnected by a collapsing element represented by a 3 ’collapsing sleeve. At the same time, the plate 1 can be additionally connected to the plate 2 by a safety cable 4. The safety cable 4, in turn, can be connected to the plates 1 and 2 by means of carbines (not shown in the figure). Cable 4 allows you to maintain the integrity of the easy-to-reset design. For example, if the window is an easily resettable structure, then the cable 4 will keep it from falling to the ground.

In FIG. Figure 2 shows the fastener assembly of an easily erasable structure in accordance with this utility model. The fastening assembly of an easily erasable structure consists of a segmented adjustable plate 1 intended for attaching to an easily erasable structure, of a plate 2 intended for attaching to a mounting opening, interconnected by a collapsing element, presented in the form of a crushing plate 3 '', which can be made adjustable by permissible pressure level. This can be achieved due to the design of the plate, including cut lines. When using such a unit during installation, the installer makes an incision on such a plate in accordance with the expected fracture loads. The collapsing plate 3 ’’ can be fastened to the plates 1 and 2 by means of fasteners. Such elements may be represented, for example, by rivets or a screw and nut. In this case, the plate 1 can be additionally connected to the plate 2 with a safety cable 4. The safety cable 4, in turn, can be connected to the plates 1 and 2 using carabiners (not shown in the figure).

The plate 1 and the plate 2 are made of materials with a higher strength than the collapsing element, for example, steel, plastic. The plate 1 is made of several tear-off segments, which allows for adjustment along the length, and each of which contains a hole for fixing the collapsing element.

The collapsing element consists of a less durable material than plates 1 and 2, for example, of 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.

The cable 4 can be made of various materials, in particular, synthetic aramid fiber. The advantages of synthetic material over steel are that it does not freeze, which positively affects the thermal characteristics of the window.

Consider an example of mounting an attachment point for an easily ejectable structure in accordance with this utility model. In this example, the window is an easily resettable construction. It should be noted that the fastener assembly can be assembled as an installer when installing the window, and the assembly can also be carried out by the manufacturer before shipment to the final consumer. In any case, the fastener assembly is easily assembled and is initially adjusted for the window and its mounting opening for fastening.

Each mounted easy-to-dismount structure must be supplied with a fastening scheme for destructible nodes, on which their fastening points are indicated in accordance with their marking (pre-calculated fracture load). Destructible nodes are attached to the window in previously designated places. Installation of safety cables on destructible nodes is carried out in accordance with the attached scheme.

In FIG. 3, the assembly of the fastener assembly is as follows: the plate 1 is connected by means of a collapsing element 3 to the plate 2. The plate 1 and the plate 2 can be additionally connected to each other by a cable 4, at the ends of which carbines can be fixed (not shown in the figure). If necessary, adjust the assembled assembly to the required length, segments with a hole for a collapsing element are torn from the plate 1. Using fasteners, the plate 1 is attached to the window 5. Next, the window is installed in the mounting opening 6 on the supporting surface 7 and is leveled, the plate 1 can be bent to the required size of the mounting seam, and the plate 2 is attached to the mounting opening 6 of the window 5. Upon completion mounting onto an easily resettable structure, a warning sticker is glued with information that this window is an easily resettable structure and any pressure beyond the design value can destroy it.

Thus, the use of this utility model makes it possible to simplify the laboriousness of mounting easily removable structures by adjusting the length of the fastener, due to its suitable application to most easily removable structures, as well as the similarity to the established method of mounting ordinary windows on anchor plates. At the same time, used in structural elements, such as a cable, ensure safe discharge of structures without harming others, which allows it to be used in production, to and directly, in a residential facility.
