Technical Field
[0001] This invention belongs to the field of fire resistance testing technology for building components, and specifically relates to an intelligent temperature-controlled fire resistance testing device for building partition wall components. Background Technology
[0002] Partition wall components are non-load-bearing wall structures used to separate interior spaces of a building. Their main function is to flexibly divide interior functional areas without increasing the building's load-bearing burden. Partition wall components include horizontal components, which are wall structures arranged horizontally in a building to separate interior spaces but do not bear vertical load-bearing functions.
[0003] A search revealed that Chinese Patent Publication No. CN113340892A, published on September 3, 2021, discloses a method for testing the fire resistance of copper conductors in fire-resistant cables. The method includes the following test steps: S1, selecting a copper conductor; S2, single-strand fire resistance test; S3, cable fire resistance test; S4, determining fire resistance performance. The above embodiment demonstrates that ambient temperature and heating time significantly affect the appearance of the copper conductor; higher temperatures and longer heating times result in a thicker oxide layer adhering to the surface of the copper conductor.
[0004] However, the device still has the following drawbacks: The inability to determine whether penetrating cracks or holes have appeared reduces the effectiveness of fire resistance tests on partition wall components. Summary of the Invention
[0005] To address the aforementioned problems, this invention provides an intelligent temperature-controlled fire resistance testing device for building partition components.

[0009] Furthermore, a storage box is installed on the outer wall of each set of built-in cylinders, a third electric push rod is installed on the top inner wall of each set of storage boxes, and a push block is installed on the output end of each set of third electric push rods.
[0010] Furthermore, two sets of rotating tubes are symmetrically installed on the inner walls of both sides of each set of storage boxes, and a set of sliding inclined plates are sleeved on the outer wall of each set of rotating tubes. Two sets of first tension springs are symmetrically installed at the bottom of each set of sliding inclined plates, and the other ends of the two sets of first tension springs are connected to the bottom inner wall of the storage box.
[0011] Furthermore, the compatible component includes two sets of bonding fan rings, one end of each set of bonding fan rings is installed on the inner wall of the heat insulation plate, a fourth electric push rod is installed on the top of each set of bonding fan rings, a heat insulation plate is installed on the output end of each set of fourth electric push rods, and each set of heat insulation plates is located directly above the bonding fan rings.
[0012] Furthermore, two sets of sealing plates are symmetrically installed on the bottom of each set of heat insulation plates. The outer wall of each set of sealing plates is slidably connected to the inner wall of the heat insulation plate. A set of slots is opened on the bottom of each set of heat insulation plates. A set of filling bag structures is set in each set of slots. A set of air pumps is installed on the top of each set of heat insulation plates. The output end of each set of air pumps is connected to the filling bag structure. A set of heat insulation film is fitted on the outer wall of each set of filling bag structures.
[0013] Furthermore, a first connecting plate is installed on one side wall of each set of fitting fan rings, a telescopic rod is installed on one side wall of each set of first connecting plates, a second connecting plate is installed on one side wall of each set of telescopic rods, one end of two sets of second tension springs is symmetrically installed on one side wall of each set of first connecting plates, the other end of each set of second tension springs is connected to the second connecting plate, a test plate is installed on one side wall of each set of second connecting plates, the two sets of test plates are slidably connected, several sets of test cavities are equally spaced on each set of test plates, and several sets of thermocouple sensors are equally spaced on the top of each set of test plates.
[0014] Furthermore, several sets of third connecting plates are installed on one side wall of each set of second connecting plates, two sets of first vertical plates are symmetrically installed on one side wall of each set of third connecting plates, one end of a set of third tension springs is installed on one side wall of each set of first vertical plates, and a set of second vertical plates is installed on the other end of each set of third tension springs. An elastic sheet is connected between the two sets of second vertical plates.
[0015] Furthermore, a set of sliding columns is installed on the side wall of each group of second vertical plates near the third tension spring, and the outer wall of each set of sliding columns is slidably connected to the first vertical plate. A set of distance measuring sensors is installed on the side wall of each group of second vertical plates.
[0016] The beneficial effects of this invention are: 1. Activate the second electric push rod to move the storage box to the suspected gap on the unexposed side of the specimen, push the cotton pad into the unexposed side of the specimen, and at the same time the inner cylinder descends, it begins to drive the gap probe through the cotton pad and into the gap. Then, continuous compression causes the gap probe and sliding tube to penetrate into the inner cylinder. The horizontal component's unexposed side is monitored for penetrating cracks and holes by a flow thermocouple sensor, and the crack depth is determined by a scale structure. When penetrating cracks or holes appear, the cotton pad will ignite, and the smoke sensor will monitor the fire resistance test effect of the horizontal partition wall component.
[0017] 2. During fire resistance testing, to ensure heat sealing, the fourth electric push rod is activated to lower the heat insulation plate. As the heat insulation plate lowers, the two sets of sealing plates slide on the outer wall of the first connecting plate, and the filling bag structure comes into contact with the top of the first connecting plate. The air pump is then activated to fill the filling bag structure, causing it to expand and fill the gaps, thereby ensuring the heat sealing and concentration effect and improving the heat insulation effect of the partition.
[0018] 3. For the irregular shape of the edge of the horizontal partition wall component, when its end face contacts the second vertical plate, the second vertical plate begins to squeeze the third tension spring with pressure. At this time, the end face state of the horizontal partition wall component can be calculated by the data difference between several sets of distance measuring sensors. When the end face contacts the elastic sheet, the elastic sheet begins to change according to the shape of the end face. At this time, the pressure is simultaneously applied to two sets of adjacent third tension springs and monitored by distance measuring sensors, which improves the monitoring effect of wrapping the irregular end face of the horizontal partition wall component.
[0019] 4. Activate the first electric push rod to raise the sealing cover, then place the horizontal partition wall component between the two sets of second connecting plates and into contact with several sets of thermocouple sensors. During placement, the two sets of second connecting plates are squeezed to adapt to the shape of the horizontal partition wall component, the second tension spring is squeezed, and parallel movement is maintained by the telescopic rod. Then, the gas nozzle is activated to heat the furnace. Hot gas comes into contact with the horizontal partition wall component through the test chamber. Multiple thermocouple sensors are evenly arranged in the test furnace and on the fire-exposed surface of the specimen, continuously measuring and feeding back the actual temperature distribution. The dense thermocouple grid measures the temperature distribution on the unexposed surface to evaluate the thermal insulation performance, improving the temperature detection effect of the thermocouple sensors on the surface of the horizontal partition wall component.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] This invention provides an intelligent temperature-controlled fire resistance testing device for building partition components. It includes a testing component 1, exemplarily such as... Figure 1 As shown, a compatibility component 3 is installed on the inner wall of the test component 1, and a penetration detection component 2 is installed on the bottom of the test component 1.
[0026] Horizontal partition walls are wall structures arranged horizontally in a building to divide interior spaces but do not bear vertical loads. Their main function is to divide different usable areas within the same floor, such as separating rooms. Their design focuses on lightweight, sound insulation, fire resistance, and flexible layout, rather than load-bearing. From a functional architectural perspective, the core function of partition walls is to horizontally divide space, working in conjunction with other horizontal components such as floor slabs and beams in spatial layout. Although floor slabs and beams are primary horizontal load-bearing components, while partition walls are non-load-bearing enclosures or partitions, they are crucial to the overall user experience.
[0027] For example, such as Figure 2 As shown, the test assembly 1 includes a test base 101, a heating furnace 102 is installed on the top of the test base 101, several sets of gas nozzles 103 are connected to the outer wall of the heating furnace 102, a heat insulation plate 106 is installed on the inner wall of the heating furnace 102, a first electric push rod 104 is installed on the top of the heating furnace 102, a sealing cover 105 is installed on the output end of the first electric push rod 104, two sets of load-bearing plates 107 are symmetrically installed on the heat insulation plate 106, and several sets of back-fire thermocouple sensors 108 are distributed in a ring array on the bottom of the sealing cover 105.
[0028] For example, such as Figure 3 , Figure 4 and Figure 5As shown, the penetration detection component 2 includes a first horizontal plate 201. The top of the first horizontal plate 201 is mounted on the bottom of the sealing cover 105. A servo motor 202 is mounted on the bottom of the first horizontal plate 201. A second horizontal plate 203 is connected to the output end of the servo motor 202. Two sets of second electric push rods 204 are symmetrically mounted on the two side walls of the second horizontal plate 203. Each set of second electric push rods 204 has an electric slide 205 mounted on its output end. Each output terminal of 205 is connected to a set of internal cylinders 206. Several sets of flowing thermocouple sensors are arranged in a circular array on the bottom of each set of internal cylinders 206. A condenser structure 207 is connected to the outer wall of each set of internal cylinders 206. A smoke sensor 208 is installed on the outer wall of each set of internal cylinders 206. A placement tube 209 is installed on the inner top wall of each set of internal cylinders 206. A compression spring 2 is installed at the bottom of each placement tube 209. At one end of each set of compression springs 210, a set of sliding tubes 211 are installed at the other end. The outer wall of each set of sliding tubes 211 is slidably connected to the inner wall of the inner cylinder 206. A set of scale structures 212 are installed on the outer wall of each set of sliding tubes 211. A set of gap probes 213 are installed at the bottom of each set of sliding tubes 211. A set of storage boxes 214 are installed on the outer wall of each set of inner cylinders 206. A set of storage boxes 214 is installed on the top inner wall of each set of storage boxes 214. The third electric push rod 215 is provided in a group. Each group of the third electric push rod 215 has a set of push blocks 216 installed on its output end. Two sets of rotating tubes 217 are symmetrically installed on the inner walls of both sides of each group of storage boxes 214. A set of sliding inclined plates 218 are sleeved on the outer wall of each set of rotating tubes 217. One end of two sets of first tension springs 219 are symmetrically installed on the bottom of each set of sliding inclined plates 218. The other end of the two sets of first tension springs 219 are connected to the bottom inner wall of the storage box 214.
[0029] A combination of cotton pad testing and gap probe method was used. The second electric push rod 204 was activated to move the storage box 214 to the suspected gap on the unexposed side of the specimen. The electric slide table 205 was then adjusted, and subsequently, the third electric push rod 215 was activated to push the push block 216 downwards. As the push block descended, it compressed the cotton pad placed inside the storage box 214. Simultaneously, the cotton pad compressed the sliding inclined plate 218. As the sliding inclined plate 218 rotated on the rotating tube 217, it passively compressed the first tension spring 219. After the bottom cotton pad fell in, the push block 216 returned to its original position. Then, the inner cylinder 206 is lowered. As the inner cylinder 206 descends, the gap probe 213 is driven to penetrate the cotton pad and penetrate into the gap. Then, continuous compression causes the gap probe 213 and the sliding tube 211 to penetrate into the inner cylinder 206. The flow thermocouple sensor monitors the penetrating cracks and holes on the unexposed surface of the horizontal component, and the crack depth is determined by the scale structure 212. When a penetrating crack or hole appears, the cotton pad will ignite, and the smoke sensor 208 will monitor it, thus improving the fire resistance test effect of the horizontal partition wall component.
[0030] For example, such as Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the compatible component 3 includes two sets of fitting fan rings 301. One end of each set of fitting fan rings 301 is installed on the inner wall of the heat insulation plate 106. A set of fourth electric push rods 302 is installed on the top of each set of fitting fan rings 301. A set of heat insulation plates 303 is installed on the output end of each set of fourth electric push rods 302. Each set of heat insulation plates 303 is located directly above the fitting fan rings 301. Two sets of sealing plates 304 are symmetrically installed on the bottom of each set of heat insulation plates 303. The outer wall of each set of sealing plates 304 is slidably connected to the inner wall of the heat insulation plate 106. A set of slots is opened on the bottom of each set of heat insulation plates 303. Each set of insulation plates 303 is equipped with a set of filling bag structures 305. Each set of insulation plates 303 has an air pump 306 mounted on its top. The output end of each air pump 306 is connected to the filling bag structure 305. Each set of insulation plates 305 has an insulation film fitted onto its outer wall. Each set of fitting fan rings 301 has a first connecting plate 307 mounted on one side wall. The bottom of each first connecting plate 307 is mounted on the top of one set of load-bearing plates 107. Each set of first connecting plates 307 has a telescopic rod 308 mounted on one side wall. Each set of telescopic rods 308 has a second connecting plate 309 mounted on one side wall. The bottom of each of the first connecting plates 309 is slidably connected to the top of the load-bearing plate 107. Two sets of second tension springs 310 are symmetrically installed on one side wall of each set of first connecting plates 307, with the other end of each set of second tension springs 310 connected to the second connecting plate 309. A set of test plates 311 is installed on one side wall of each set of second connecting plates 309, and the two sets of test plates 311 are slidably connected. Several sets of test chambers 312 are evenly spaced on each set of test plates 311. Several sets of thermocouple sensors 313 are evenly spaced on the top of each set of test plates 311. Several sets of third connecting plates 309 are installed on one side wall of each set of second connecting plates 309. Each set of third connecting plates 314 has two sets of first vertical plates 315 symmetrically installed on one side wall. Each set of first vertical plates 315 has one end of a set of third tension springs 316 installed on one side wall. Each set of third tension springs 316 has a set of second vertical plates 317 installed on the other end. An elastic sheet 318 connects the two sets of second vertical plates 317. Each set of second vertical plates 317 has a set of sliding columns 319 installed on the side wall near the third tension springs 316. The outer wall of each set of sliding columns 319 is slidably connected to the first vertical plate 315. Each set of second vertical plates 317 has a set of distance sensors 320 installed on one side wall.
[0031] During the fire resistance test of the horizontal partition wall component, the first electric push rod 104 is activated to raise the sealing cover 105. Then, the horizontal partition wall component is placed between two sets of second connecting plates 309 and in contact with several sets of thermocouple sensors 313. During placement, the two sets of second connecting plates 309 are squeezed to adapt to the shape of the horizontal partition wall component, and the second tension spring 310 is squeezed. Parallel movement is maintained by the telescopic rod 308. Then, the gas nozzle 103 is activated to heat the furnace. The hot gas comes into contact with the horizontal partition wall component through the test chamber 312. At this time, the first electric push rod is activated to drive several sets of back-fire surface thermocouple sensors 108 to abut against the back-fire surface of the horizontal component. Multiple thermocouple sensors 313 are evenly arranged in the test furnace and on the fire-exposed surface of the specimen, continuously measuring and feeding back the actual temperature distribution. The dense thermocouple grid measures the temperature distribution on the back-fire surface to evaluate the thermal insulation performance, which improves the temperature detection effect of the thermocouple sensors on the surface of the horizontal partition wall component.
[0032] For the irregular shape of the edge of the horizontal partition wall component, when its end face contacts the second vertical plate 317, the second vertical plate 317 begins to compress the third tension spring 316 with pressure. At this time, the end face state of the horizontal partition wall component can be estimated by the data difference between several sets of distance measuring sensors 320. When the end face contacts the elastic sheet 318, the elastic sheet 318 begins to change according to the shape of the end face. At this time, the pressure acts on two adjacent sets of third tension springs 316 at the same time, and is monitored by the distance measuring sensor 320, which improves the monitoring effect of wrapping the irregular end face of the horizontal partition wall component.
[0033] During fire resistance testing, to ensure heat sealing, the fourth electric push rod 302 is activated to lower the heat insulation plate 303. As the heat insulation plate 303 lowers, the two sets of sealing plates 304 slide on the outer wall of the first connecting plate 307, causing the filling bag structure 305 to abut against the top of the first connecting plate 307. The air pump 306 is then activated to fill the filling bag structure 305, causing it to expand and fill the gaps, thereby ensuring heat sealing and concentration, and improving the heat insulation effect of the partition.
[0034] The second electric push rod 204 is activated, which moves the storage box 214 to the suspected gap on the unexposed side of the specimen. The cotton pad is pushed into the unexposed side of the specimen. As the inner cylinder 206 descends, it begins to drive the gap probe 213 through the cotton pad and into the gap. Then, continuous compression causes the gap probe 213 and the sliding tube 211 to penetrate into the inner cylinder 206. The flow thermocouple sensor monitors the penetrating cracks and holes on the unexposed side of the horizontal component. The crack depth is then determined by the scale structure 212. When a penetrating crack or hole appears, the cotton pad will ignite. The smoke sensor 208 is then used for monitoring, which improves the fire resistance test effect of the horizontal partition wall component.
[0035] During fire resistance testing, to ensure heat sealing, the fourth electric push rod 302 is activated to lower the heat insulation plate 303. As the heat insulation plate 303 lowers, the two sets of sealing plates 304 slide on the outer wall of the first connecting plate 307, causing the filling bag structure 305 to abut against the top of the first connecting plate 307. The air pump 306 is then activated to fill the filling bag structure 305, causing it to expand and fill the gaps, thereby ensuring heat sealing and concentration, and improving the heat insulation effect of the partition.
[0036] For the irregular shape of the edge of the horizontal partition wall component, when its end face contacts the second vertical plate 317, the second vertical plate 317 begins to compress the third tension spring 316 with pressure. At this time, the end face state of the horizontal partition wall component can be estimated by the data difference between several sets of distance measuring sensors 320. When the end face contacts the elastic sheet 318, the elastic sheet 318 begins to change according to the shape of the end face. At this time, the pressure acts on two adjacent sets of third tension springs 316 at the same time, and is monitored by the distance measuring sensor 320, which improves the monitoring effect of wrapping the irregular end face of the horizontal partition wall component.
[0037] The first electric push rod 104 is activated to raise the sealing cover 105. Then, the horizontal partition wall component is placed between two sets of second connecting plates 309 and in contact with several sets of thermocouple sensors 313. During placement, the two sets of second connecting plates 309 are squeezed to adapt to the shape of the horizontal partition wall component. The second tension spring 310 is squeezed and parallel movement is maintained by the telescopic rod 308. Then, the gas nozzle 103 is activated to heat the furnace. The hot gas comes into contact with the horizontal partition wall component through the test chamber 312. Multiple thermocouple sensors 313 are evenly arranged in the test furnace and on the fire-exposed surface of the specimen to continuously measure and report the actual temperature distribution. The dense thermocouple grid measures the temperature distribution on the unexposed surface to evaluate the thermal insulation performance, which improves the temperature detection effect of the thermocouple sensors on the surface of the horizontal partition wall component.
[0038] Based on the aforementioned intelligent temperature-controlled fire resistance testing device for building partition components, this invention also proposes a method for using the intelligent temperature-controlled fire resistance testing device for building partition components. Exemplarily, the method includes: Heat is generated by an array of multiple high-precision gas nozzles or electric heating elements distributed within the test furnace; The intelligent temperature control module does not simply output power according to a preset power, but dynamically adjusts it based on a standard curve. The furnace temperature is rapidly increased during the initial heating phase, and then the fuel / electricity input is precisely controlled based on real-time feedback. Ensure that the deviation between the average temperature inside the furnace and the standard curve is strictly controlled within the allowable range, thereby providing a standardized and reproducible thermal attack environment for the specimens; Multi-dimensional real-time monitoring and data acquisition system: perception and feedback. This is the perception layer for realizing "intelligent temperature control" and performance evaluation.
[0039] The system is equipped with multiple high-performance sensor arrays: Furnace temperature monitoring: Multiple thermocouples are evenly arranged inside the test furnace and on the surface of the specimen exposed to heat. Continuous measurement and feedback of the actual temperature distribution serve as a direct basis for adjusting the temperature control system. Specimen back-exposed surface monitoring: A dense thermocouple grid measures the temperature distribution on the back-exposed surface.
[0040] This is key data for assessing thermal insulation performance (e.g., average temperature rise exceeding 140°C or single-point temperature exceeding 180°C). Integrity monitoring: A combination of cotton pad testing and gap probes is used.
[0041] A robotic arm or automated device periodically attaches cotton pads to suspected gaps on the unexposed side of the specimen, and uses a gap probe for measurement. Automatically detects whether penetrating cracks or holes have appeared (e.g., igniting the cotton pad or penetrating with a probe).
[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
