Abstract

This application provides a training device for fireproof sealing material construction techniques, involving fireproof sealing materials, a main support system, and hole modules and gap modules, including at least one hole module or gap module, which is detachably installed on the main support system to form a training structure for fireproof sealing material construction. This application creatively introduces a "detachable release layer structure" as its core design. This structure (such as a polypropylene 3D-printed liner) is attached to the inner wall of the module. After training, it can be removed as a whole along with the cured sealing material, ensuring that the main body of the module, composed of a stainless steel frame and poplar wood substrate blocks, remains intact and can be immediately used for the next round of training.

Description

Technical Field

[0001] This invention relates to the field of fireproof sealing, and more specifically, to a training device for fireproof sealing material construction techniques. Background Technology

[0002] Fire sealing in buildings is a crucial measure to ensure fire safety and prevent the spread of fire. It is widely used to seal holes and gaps in walls or floors where cables, pipes, and air ducts penetrate. In the training of fire protection engineering professionals, the skills training of construction personnel, and qualification certification assessments, practical training is a core component for mastering the construction techniques of various materials such as fireproof putty, fireproof boards, fireproof sealants, and fire-resistant bags.

[0003] Currently, the main training methods have the following significant drawbacks:

[0004] Training costs are high and cannot be repeated: Traditional training often relies on "on-the-job training" at real construction sites or on one-off simulated walls. The former is inefficient due to limitations in project schedule and safety; the latter, once the sealing material is applied and cured, adheres firmly to the wall structure and is difficult to remove, making the simulated wall and its sealing structure disposable and unable to be reused, resulting in huge material waste and training cost pressure.

[0005] The training scenarios are limited and the simulation level is insufficient: Existing training devices often have fixed structures, making it difficult to flexibly and cost-effectively simulate the diverse types of holes in buildings (such as circular pipe holes of different diameters and square cable tray holes) and structural gaps (such as building expansion joints). At the same time, it is also difficult to simulate the construction conditions of different substrate surfaces such as concrete, tiles, and painted walls, resulting in insufficient adaptability of trainees when facing real and complex working conditions.

[0006] Training quality assessment is difficult and difficult to standardize: Due to the lack of a unified and comparable training platform, instructors find it difficult to conduct intuitive and fair quantitative evaluation of the construction results (such as filling density, sealing flatness, and installation standardization) of different trainees under the same conditions, which affects the effectiveness of teaching feedback and the fairness of skills assessment.

[0007] Therefore, we have made improvements and proposed a training device for fireproof sealing material construction techniques. Summary of the Invention

[0008] The purpose of this invention is to provide a training device for fireproof sealing material construction techniques, which creatively incorporates a "removable demolding layer structure" as its core design. This structure (such as a polypropylene 3D-printed liner) is attached to the inner wall of the module. After training, it can be removed as a whole, along with the cured sealing material, ensuring that the main body of the module, composed of a stainless steel frame and poplar wood substrate, remains intact and can be immediately used for the next round of training. This fundamentally solves the industry problem of permanent adhesion between the sealing material and the training device, transforming the device from a "disposable consumable" to a "reusable teaching aid," resulting in extremely low cost per training session.

[0009] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0010] Fireproof sealing material construction technique training device, including:

[0011] Main support system;

[0012] Hole modules and slot modules, comprising at least one hole module or slot module, which is detachably mounted on the main support system to form a training structure for the application of fire-stopping materials;

[0013] A release layer structure, which is detachably attached to the inner wall of the hole module and the slot module, is used to prevent the sealing material from permanently bonding to the module body;

[0014] The release layer structure can be removed from the hole module or gap module along with the fireproof sealing material after the fireproof sealing material has cured, so that the module body can be reused.

[0015] As a preferred technical solution of this application, the main support system includes a perforated metal plate, and the mounting holes on the perforated metal plate are arranged in a standard grid to provide mounting interfaces for the modules.

[0016] As a preferred technical solution of this application, the hole module includes a stainless steel frame and at least one base block detachably fixed therein. The base block is fixed to the inside of the stainless steel frame by bolts. The base block is made of poplar wood blocks and is used to simulate building structures.

[0017] The hole module and the slot module have the same structure.

[0018] As a preferred technical solution of this application, the release layer structure is a 3D printed liner made of a low surface energy material, preferably polypropylene, and its inner surface can be made with a texture that simulates real building materials.

[0019] As a preferred technical solution of this application, the 3D printed liner is attached to the inner wall of the substrate block with double-sided adhesive, which facilitates overall replacement.

[0020] As a preferred technical solution of this application, it also includes a release agent coating sprayed on the surface of the 3D printed liner and the substrate block, as part of the release layer structure, for further reducing adhesion.

[0021] As a preferred technical solution of this application, the outer surface of the substrate block can be treated with a finishing process, including painting, pasting tiles, painting concrete, or pasting wallpaper, to improve the realism of the construction scene.

[0022] As a preferred technical solution of this application, the substrate block of the hole module is drilled with holes of different diameters to simulate the through holes of a circular pipe;

[0023] The position of the base block of the gap module is adjustable to form gaps of different widths, simulating building expansion joints.

[0024] As a preferred technical solution of this application, the fireproof sealing materials adapted to the device include fireproof putty, fireproof board, rock wool, fireproof sealant, fire-resistant bag and fire-resistant ring.

[0025] The main support system also includes a movable main frame and a movable sub-frame. The bottom of the movable main frame and the movable sub-frame are equipped with casters. The perforated metal upright plate is located inside the movable main frame. Support frames are slidably mounted on both sides of the perforated metal upright plate for fixed connection with the movable main frame. Adjusting bolts are threadedly connected to the perforated metal upright plate.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] In the scheme of this application:

[0028] 1. This invention creatively introduces a "detachable release layer structure" as its core design. This structure (such as a polypropylene 3D-printed liner) is attached to the inner wall of the module. After training, it can be removed as a whole, along with the cured sealing material, ensuring that the main body of the module, composed of a stainless steel frame and poplar wood substrate, remains intact and can be immediately used for the next round of training. This fundamentally solves the industry problem of permanent adhesion between the sealing material and the training device, transforming the device from a "disposable consumable" into a "reusable teaching aid," resulting in extremely low cost per training session.

[0029] 2. By replacing different hole modules (with pre-fabricated holes of varying diameters) and gap modules (with adjustable gap width), various typical fire-sealing conditions such as pipe penetration, cable tray penetration, and building expansion joints can be quickly simulated. The outer surface of the base block (poplar block) can be finished (e.g., painted, tiled), highly replicating real building walls and enhancing the realism and practicality of training;

[0030] Meanwhile, the hole module and the slot module adopt the same "stainless steel frame + replaceable base material block" main structure, which standardizes the production, maintenance and management of the modules, and reduces manufacturing costs and spare parts complexity.

[0031] 3. The main support system uses perforated metal uprights with standard grid-like installation interfaces, allowing for quick and accurate module assembly and disassembly. The device is equipped with casters and an adjustable support structure, ensuring convenient movement and stable support to adapt to different training environments. The release layer is attached with double-sided adhesive, making replacement simple and quick, further reducing maintenance difficulty and time costs. Attached Figure Description

[0043] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0044] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0045] In the description of this invention, it should be noted that the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use, or the orientation or positional relationship commonly understood by those skilled in the art. These terms are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] Please see Figures 1 to 4 The present invention provides a technical solution: a training device for construction techniques of fireproof sealing materials, and a main support system 1;

[0047] Hole module 2 and slot module 3, comprising at least one hole module 2 or slot module 3, are detachably mounted on the main support system 1 to form a training structure for the application of fire-resistant sealing materials;

[0048] The release layer structure 4 is detachably attached to the inner wall of the hole module 2 and the slot module 3 to prevent the sealing material from permanently bonding to the module body;

[0049] The release layer structure 4 can be removed from the hole module 2 or the gap module 3 along with the fireproof sealing material after the fireproof sealing material has cured, so that the main body of the module can be reused.

[0050] Because the invented fireproof sealing material construction technique training device has the above structure, its core innovation lies in the reusability of the training device itself through the detachable release layer structure 4. During construction training, the fireproof sealing material only comes into contact with the release layer 4; after training, the cured sealing material along with the release layer 4 can be removed as a whole, while the hole module 2 and gap module 3, which are the main components of the training structure, are retained. This greatly reduces the material cost per training session and solves the waste problem caused by the single-use of existing training walls.

[0051] The main support system 1 includes a perforated metal plate 11, on which mounting holes are arranged in a standard grid to provide mounting interfaces for modules.

[0052] Because the fireproof sealing material construction technique training device invented has the above structure, the porous metal upright plate 11 is a standardized mounting base. The gridded mounting holes on it provide flexible and adjustable mounting positions for the hole module 2 and the gap module 3, so that modules of different sizes and different arrangements can be conveniently and firmly installed on the bracket. Thus, multiple training scenarios can be combined on a single main bracket, improving the versatility and flexibility of the device.

[0053] The hole module 2 includes a stainless steel frame 21 and at least one base material block 22 detachably fixed therein. The base material block 22 is fixed to the inside of the stainless steel frame 21 by bolts. The base material block 22 is made of poplar wood blocks and is used to simulate building structures.

[0054] The hole module 2 and the gap module 3 have the same structure.

[0055] Because the invented fireproof sealing material construction technique training device has the above structure, its modules adopt a combination design of stainless steel frame 21 and poplar wood substrate blocks 22. The stainless steel frame 21 provides a robust support structure, ensuring the structural stability and durability of the module under repeated installation, disassembly, and construction forces. Poplar wood blocks are lightweight, easy to process (drilling, cutting, surface treatment), and inexpensive, making them an ideal choice for simulating building wall substrates. The bolted connection method allows for individual replacement of damaged or worn substrate blocks, further reducing maintenance costs. The hole module and the gap module have the same main structure, achieving standardization of core components and facilitating production, inventory management, and interchangeability.

[0056] The release layer structure 4 is a 3D printed liner 41 made of a low surface energy material, preferably polypropylene, and its inner surface can be made with a texture that simulates real building materials.

[0057] Because the invented fireproof sealing material construction technique training device has the above structure, 3D printing technology allows the lining to be precisely molded and perfectly fit the inner walls of holes or gaps machined on the substrate block. The use of low surface energy materials such as polypropylene effectively reduces adhesion to fireproof sealing materials (such as fireproof putty, sealant, etc.). The pre-set textures on the inner surface (such as simulating the rough surface of concrete, the smooth surface of metal pipes, etc.) increase the realism of the training, allowing trainees to practice construction techniques under conditions close to actual working conditions.

[0058] The 3D printed liner 41 is attached to the inner wall of the substrate block 22 with double-sided adhesive, making it easy to replace as a whole.

[0059] Because the invented fireproof sealing material construction technique training device has the above structure, double-sided adhesive is a simple, reliable, and extremely low-cost fixing method. It can maintain the stability of the lining during training, and when replacement is needed, it allows the user to easily peel the lining along with the cured sealing material on it from the base block, achieving rapid cleaning and resetting, and ensuring the high efficiency of the training process.

[0060] It also includes a release agent coating 42 sprayed on the surface of the 3D printed liner 41 and the substrate block 22, as part of the release layer structure, for further reducing adhesion.

[0061] Because the fireproof sealing material construction technique training device has the above structure, the release agent coating 32 (such as silicone oil, wax-based release agent, etc.) forms an isolation film on the surface of the lining 41, providing additional and more reliable anti-sticking protection for some fireproof sealing materials with particularly strong adhesion (such as some fireproof sealants), ensuring that even in extreme cases, the cured material can be smoothly and completely removed together with the lining, thereby protecting the reusability of the substrate block and the lining itself.

[0062] The outer surface of the substrate block 22 can be finished, including painting, tiling, applying concrete, or wallpapering, to enhance the realism of the construction scene.

[0063] Because the invented fireproof sealing material construction technique training device has the above structure, it can highly simulate the surfaces of various walls or structures in real buildings by applying diverse finishing treatments to the outer surface of the substrate block. For example, trainees can practice grouting on tiled walls or edge sealing on painted walls. This highly realistic training environment helps trainees master the construction techniques and precautions on different substrates, effectively enhancing the practical value of the training.

[0064] The base block 22 of the hole module 2 is drilled with holes 23 of different diameters to simulate the through holes of circular pipes; the base block 22 of the gap module 3 is adjustable in position to form gaps 24 of different widths to simulate building expansion joints.

[0065] Because the invented fireproof sealing material construction technique training device has the above structure, by pre-drilling holes 23 of different diameters on the same base material block 22, or by adjusting the relative positions of multiple base material blocks 22 to form gaps 24 of variable width, a single module can provide training conditions of various specifications. This greatly expands the training coverage of a single module, allowing instructors to achieve pipe penetration sealing from DN50 small diameter to DN150 or even larger pipe diameters, and sealing training of gaps of different widths from 5mm to 20mm, without having to prepare a large number of fixed modules of different specifications. This significantly improves the training efficiency and cost-effectiveness of the device.

[0066] The fire-stopping materials compatible with the device include fireproof putty, fireproof board, rock wool, fireproof sealant, fire-resistant bag and fire-resistant ring.

[0067] Because of its structure, the invented fire-stopping material construction technique training device, with its modular design and detachable demolding layer, is compatible with various mainstream fire-stopping materials and construction methods. Trainees can practice the construction of filling materials (fireproof putty, fire-resistant bags), board materials (fireproof boards), fiber materials (rock wool), and sealing materials (fireproof sealant) sequentially or selectively on the same device, and can also practice the installation of fire-resistant rings. This provides trainees with a comprehensive, one-stop integrated skills training platform.

[0068] The main support system 1 also includes a movable main frame 12 and a movable sub-frame 13. The bottom of the movable main frame 12 and the movable sub-frame 13 are both equipped with movable wheels 14. The perforated metal upright plate 11 is located inside the movable main frame 12. Support frames 16 are also slidably assembled on both sides of the perforated metal upright plate 11 for fixed connection with the movable main frame 12. Adjusting bolts 15 are threadedly connected to the perforated metal upright plate 11.

[0069] Because the invented fireproof sealing material construction technique training device has the above structure, the movable wheels 14 at the bottom of the main and auxiliary frames give the entire device good mobility, making it easy to move flexibly between training classrooms, workshops, and assessment sites. The design of the support frame 16 and the adjusting bolts 15 allows the installation height of the perforated metal upright plate 11 within the movable auxiliary frame to be adjusted, and it can be locked in place by the adjusting bolts 15. This adapts to the operating habits of trainees of different heights, or simulates construction positions at different heights (such as holes through floor slabs and holes through walls), improving ergonomics and adaptability to training scenarios.

[0070] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
