Description

[0001] The utility model relates to equipment for training employees (workers) of fire departments, emergency rescue services, as well as individuals, and for studying the influence of fire spread on objects under study when creating situations similar to a fire, specifically to the design of a confined space limiter, inside which a simulation of the combustion process is created, intended for the short-term stay of a person or objects under study inside this space.

[0002] For the purposes of this description, the term "Test Block Container" (TBC) is used, meaning a confined space limiter within which a microclimate and temperature regime of a fire is created, or a controlled partial imitation of the results of the combustion process, intended for the short-term stay of a person or objects under study within this space.

[0003] At the present time, there is a need to conduct training to improve the behavior of personnel of fire protection units and emergency rescue services, as well as employees of the Ministry of Emergency Situations when creating a simulated fire - creating a source of flame spread, smoke, studying the spread of fire and its impact on various models, etc. For these purposes, fire simulators, artificial structures containing a flame generator, a technical control unit, at least one test block container, a ventilation system, various sensors, etc., can be used, for example, a Modular Fire Simulator (patent document US 5203707 (A); IPC A62C 99 / 00, G09B 19 / 00, G09B 9 / 00; published on 20.04.1993), as well as an Installation for Simulating Fires (patent document EP 3195904 (A1); IPC A62C 99 / 00, G09B 9 / 00; published on 26.07.2017).

[0004] The prototype of the utility model is a technical solution according to the patent Modular building for a fire simulator (patent US 12456388 (B1); IPC A62C 99 / 00, E04B 1 / 24, E04B 1 / 343; published 10 / 28 / 2025), containing a metal frame, an upper covering and side walls equipped with closed openings.

[0005] The disadvantage of the prototype, which initiates the problem solved by the utility model, is the possibility of deformations (warping and / or burnout when applying thermal loads) of the internal surfaces of the side walls, which reduces the reliability of the structure.

[0006] The utility model was created to solve the technical problem of developing a test block container for a fire simulator, ensuring the reliability of the design.

[0007] The solution to the stated problem is a test block container for a fire simulator (TBC) containing a metal frame, a floor, an upper covering and side walls equipped with closed openings, wherein the side walls are formed by internal and external partitions with a gap between them, the external partition is made of sheet metal fixed to the external side of the frame, the internal partition is made in the form of two layers of metal plates, the plates of the first layer are fixed to the internal side of the frame, the plates of the second layer are fixed to the internal side of the frame, superimposed on the plates of the first layer and closing the gaps between the opposite ends of the plates of the first layer, wherein the plates of the second layer are installed with gaps between the opposite ends, respectively.

[0008] The technical result achieved through the implementation of the utility model is an increase in reliability, consisting in extending the failure-free period and increasing durability, as well as improving maintainability, which increases the reliability of the design.

[0009] In special cases of execution:

[0010] To optimize assembly operations, the number of standard sizes and interchangeability of parts, the first layer plates can be installed in a staggered pattern;

[0011] To improve maintainability, when replacing the plates of the first or second layer, if necessary, the fastening unit of the plates of the first and second layers can be made in the form of a bolt passing through coaxial holes made in the plates of the first and in the plates of the second layer, as well as holes in the frame, screwed into a nut located in the gap between the internal partition of the side wall and the frame, while the nut can be made in the form of an elongated transition nut (coupling) according to DIN 6334 or manufactured according to individual drawings.

[0012] The following graphic materials are used to explain the essence of the utility model:

[0017] Fig. 5 - installation of the second layer plates overlapping the first layer plates (fragment);

[0018] Fig. 6 - fragment Fig. 3.

[0019] The test block-container IBC is the main element of the fire simulator and contains a metal frame 1, a floor 2, an upper covering 3 and side walls 4, equipped with closed openings 5.

[0020] The IBC can preferably be made in the form of a parallelepiped (Fig. 1).

[0021] Frame 1 is made of metal, equipped with vertical load-bearing supports 22 with horizontal crossbars 23 installed on them and lathing 24 fixed to them (Fig. 2). Vertical supports 22 and horizontal crossbars 23 can be made of angle steel profile of at least 140×140×9 GOST 8509-93, and / or square steel profile of at least 100×100×3, or rectangular steel profile of at least 100×50×3 GOST 30245-2003 or GOST 8639-82. The lathing 24 can be made from a square steel section of at least 25×25×2 and / or a rectangular steel section of at least 40×20×2 GOST 30245-2003 or GOST 8639-82, and / or a hot-rolled steel strip of at least 25×4 mm according to GOST 103-76 103-2006, and / or a hot-rolled square of at least 20 mm in size according to GOST 2591-2006, and / or sheet steel of at least 3 mm in thickness according to GOST 19903-2015.

[0022] The side walls 4 are provided with closed openings 5, for example doors, for passage into the interior space or technological hatches for supplying and removing air or combustion products from the interior space of the IBC.

[0023] The side walls 4 are formed by internal 6 and external 7 partitions with a gap 8 between them (Fig. 3). The gap 8 can be filled with a heat-resistant thermal insulation material, for example, expanded clay gravel, basalt wool, ceramic filler, etc.

[0024] The external partition 7 is made of sheet metal 9, fixed to the outer side of the frame 1. To form the external surface, standard rolled sheet steel with a thickness of at least 2 mm in accordance with GOST 19903-2015 and / or steel sheets with rhombic and lentil corrugation of at least 3 mm in accordance with GOST 8568-77, cut in accordance with the design development, can be used.

[0025] The internal partition 6 facing the closed space of the IBC is made in the form of two layers 10, 11 of metal plates.

[0026] The plates of the first layer 12 are fixed on the frame 1 and installed with gaps 13 between the opposite ends (Fig. 4).

[0027] The plates of the second layer 14 are fixed on the frame 1, placed on the plates of the first layer 12 and cover the gaps 13 between the opposite ends of the plates of the first layer 12. The plates of the second layer 14 are installed with gaps 15 between the opposite ends, respectively (Fig. 5).

[0028] The production of IBC can be carried out by generally accepted methods used in the production of metal structures using welded or threaded connections.

[0029] The utility model is implemented as follows.

[0030] During internal fire tests, a fire situation is simulated within the IBC, with the inner surfaces of the side walls subjected to localized thermal loads. Thermal loads cause thermal expansion of the first and second layer plates. Since each plate has the ability to linearly expand within the gaps between its opposite ends, it prevents its impact on adjacent plates, reducing the likelihood of warping of the inner surface and preventing warping, thereby increasing durability. Since the surfaces of the second layer plates cover the gaps between the first layer plates, uncontrolled combustion product release from the IBC is prevented, which corresponds to the fire test conditions.

[0031] In case of unacceptable deformation of the internal surface area of ​​the IBC, the plates forming this area are replaced with new ones, and the remaining plates remain unchanged, resulting in improved maintainability and durability of the structure.

[0032] It is obvious that the implementation of the utility model ensures the implementation of the technical result.

[0033] In special cases of execution.

[0034] The plates 12 of the first layer can be installed in a staggered manner (Fig. 4).

[0035] The fastening unit 16 of the plates of the first and the plates of the second layer of the internal partition of the side wall is made in the form of a bolt 17 passing through coaxial holes made in the plates of the first 18, the plates of the second layer 19 and the frame 20, screwed into a nut 21 located in the space between the internal partition of the side wall and the frame (lathing) (Fig. 6).

[0036] Nut 21 can be made in the form of an elongated transition nut (coupling) according to DIN 6334 or manufactured according to individual drawings.
