Description
Technical Field
[0001] This utility model relates to the field of testing equipment, specifically a fire resistance testing device for building materials. Background Technology
[0002] Building materials are a general term for materials used in civil engineering and construction projects. They are usually classified into three main types according to their uses: structural materials, decorative materials, and special materials. The main function of fire resistance testing equipment for building materials is to evaluate the fire resistance performance of materials, ensure building safety, and reduce fire risks. These devices test the flame retardancy of building materials under specific conditions by simulating real or extreme fire scenarios. However, in existing technologies, materials are fixed by upper and lower clamps, while the ignition device is located on the left side of the material. This makes it impossible to conduct comprehensive testing of the material, which may lead to deviations in the measurement data and reduce its practicality.
[0003] To address the aforementioned issues, a fire resistance testing device for building materials, published in Chinese Patent Publication No. CN222439460U, utilizes the coordinated operation of various structures within the testing mechanism to place the building materials on the upper surface of a rotating plate for comprehensive testing. This also prevents workers from directly contacting high temperatures, thereby improving the accuracy of the test results and enhancing practicality.
[0004] While the comparative patent solves the problem of the inability to perform comprehensive testing of materials, which could lead to inaccurate measurement data, the device cannot extinguish the fire in a timely manner after the material is burning. It requires opening the door and using external fire extinguishing equipment to put out the fire, which causes considerable trouble for the staff and reduces the practicality of the device.
[0005] Regarding the aforementioned technologies, this device has the drawback that it cannot extinguish the fire of materials in a timely manner after they start burning. It requires opening the door and using external fire extinguishing equipment to put out the fire, which causes considerable trouble for the staff and reduces the practicality of the device. Utility Model Content
[0006] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a fire resistance testing device for building materials. It features a sealing plug that seals the inner wall of the vent cylinder, ensuring the testing chamber is sealed and lacks the necessary oxygen for combustion. This allows the building materials to extinguish automatically, eliminating the need for external fire extinguishers and improving safety. It also solves the problem of the inability to extinguish burning materials promptly, requiring the opening of the chamber and the use of external fire extinguishers, which is inconvenient for staff and reduces the device's practicality.
[0007] (II) Technical Solution To achieve the goal of sealing the inner wall of the gas outlet with the aforementioned sealing plug, thus ensuring that the interior of the testing chamber is in a closed state and there is no oxygen for combustion, the building materials will automatically extinguish, thereby eliminating the need for personnel to use external fire extinguishing tools and improving safety, this utility model provides the following technical solution: a fire resistance testing device for building materials, including a testing machine body, an operator provided on the front of the testing machine body, a testing chamber opened on the front of the testing machine body, and a combustion component installed inside the testing chamber.
[0008] An air outlet cylinder is fixedly sleeved on the inner top arm of the testing chamber. An air outlet pipe is fixedly connected to the top of the air outlet cylinder. An installation rod is fixedly connected to the inner wall of the air outlet cylinder. An electric telescopic rod is fixedly connected to the bottom of the installation rod. A support plate is provided at the bottom of the electric telescopic rod. A sealing plug is fixedly connected to the bottom of the support plate. The shape of the sealing plug is the same as that of the air outlet cylinder. A filter component is provided at the top of the support plate.
[0009] As a preferred embodiment of this utility model, the inner wall of the testing chamber is rotatably connected to a tempered glass door, and a handle is fixedly connected to the front of the tempered glass door.
[0010] As a preferred embodiment of this utility model, the air outlet is shaped like a frustum cylinder, and the top diameter of the air outlet is smaller than its bottom diameter.
[0011] As a preferred technical solution of this utility model, the combustion component includes a burner fixedly connected to the inner wall of the detection chamber, and the top of the burner is provided with a flame head.
[0012] As a preferred embodiment of this utility model, a support plate is fixedly connected to the inner wall of the testing chamber, and the support plate is composed of multiple thin rods arranged in a crisscross pattern.
[0013] As a preferred embodiment of this utility model, the filter component includes a connecting rod fixedly connected to the top of the support plate, a lifting plate fixedly connected to the top of the connecting rod, and a filter element detachably installed on the top of the lifting plate.
[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a fire resistance testing device for building materials, which has the following beneficial effects: 1. After the fire resistance test is completed, the electric telescopic rod is activated. The electric telescopic rod will move the sealing plug upward, and the sealing plug will seal the inner wall of the air outlet. This will confirm that the interior of the test chamber is in a closed state and there is no oxygen for combustion. The building materials will automatically extinguish, thus eliminating the need for staff to use external fire extinguishing tools to put out the fire, thereby improving safety.
[0015] 2. When the combustion gas passes through the gas outlet, it passes through the filter element, thereby filtering out harmful substances. When the support plate moves upward, it can drive the lifting plate and the filter element upward through the connecting rod, so that the filter element extends to the outside of the gas outlet pipe, and the filter element can be replaced, thus extending the service life of the device.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0019] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention, which provides a fire resistance testing device for building materials, including a testing machine body 1. The testing machine body 1 is an existing device and will not be explained in detail here. An operator 2 is provided on the front of the testing machine body 1, and a testing chamber 3 is opened on the front of the testing machine body 1. A combustion component is installed inside the testing chamber 3. An air outlet cylinder 8 is fixedly sleeved on the inner top arm of the testing chamber 3. An air outlet pipe 9 is fixedly connected to the top of the air outlet cylinder 8. An installation rod 10 is fixedly connected to the inner wall of the air outlet cylinder 8. An electric telescopic rod 11 is fixedly connected to the bottom of the installation rod 10. A support plate 12 is provided at the bottom of the electric telescopic rod 11. A sealing plug 13 is fixedly connected to the bottom of the support plate 12. The shape of the sealing plug 13 is the same as that of the air outlet cylinder 8. When the electric telescopic rod 11 is activated, the electric telescopic rod 11 will drive the sealing plug 13 to move upward, thereby sealing the inner wall of the air outlet cylinder 8. A filter component is provided on the top of the support plate 12.
[0020] Specifically, a tempered glass door 4 is rotatably connected to the inner wall of the testing chamber 3. A handle is fixedly connected to the front of the tempered glass door 4. By closing the tempered glass door 4 with the handle, the testing chamber 3 can be sealed, thereby allowing the fire resistance of the building materials inside the testing chamber 3 to be tested.
[0021] Specifically, the exhaust cylinder 8 has a frustum-shaped cylindrical structure, with the top diameter of the exhaust cylinder 8 being smaller than its bottom diameter, so that the combustion gas inside the detection chamber 3 can be released through the exhaust cylinder 8.
[0022] Reference Figure 1-2 The combustion component includes a burner 5 fixedly connected to the inner wall of the detection chamber 3. The top of the burner 5 is provided with a flame head 6. There are multiple flame heads 6, which are evenly fixedly connected to the top of the burner 5. Thus, the burner 5 can evenly burn the building materials through the flame heads 6.
[0023] Furthermore, a support plate 7 is fixedly connected to the inner wall of the testing chamber 3. The support plate 7 is made up of multiple thin rods arranged in a crisscross pattern, so that the building materials can be placed on top of the support plate 7, thereby supporting the building materials.
[0024] Reference Figure 1-4 The filter component includes a connecting rod 14 fixedly connected to the top of the support plate 12. A lifting plate 15 is fixedly connected to the top of the connecting rod 14. A filter element 16 is detachably installed on the top of the lifting plate 15. When the combustion gas is discharged through the gas outlet 8, it will pass through the filter element 16, and the harmful substances in it will be filtered by the filter element 16. When the support plate 12 moves upward, the lifting plate 15 and the filter element 16 can be moved upward through the connecting rod 14, so that the filter element 16 extends to the outside of the gas outlet pipe 9, and the filter element 16 can be replaced.
[0025] During use, the building materials are placed on the support plate 7, and the burner 5 can burn the building materials evenly through the flame head 6. When the combustion gas is discharged through the gas outlet 8, it will pass through the filter element 16, and the harmful substances in it will be filtered by the filter element 16. After the fire resistance test is completed, the electric telescopic rod 11 is activated. The electric telescopic rod 11 will drive the sealing plug 13 to move upward, and the sealing plug 13 will seal the inner wall of the air outlet 8. Thus, the interior of the test chamber 3 is in a closed state, and there is no condition for combustion oxygen. The building materials will automatically extinguish, so there is no need for staff to use external fire extinguishing tools to extinguish the fire.
[0026] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
