Example Embodiment
[0009] Specific embodiment 1: As shown in Figures 1 to 4, the fire resistance test device for measuring single-layer frames in this embodiment includes an outer furnace body 1, an inner furnace body 2, an oil pipeline 5, and four to eight combustions. The nozzle 6, the oil supply device 7, the weathering pipe 8, the fan 9, the flue gas duct 10 and the measuring device 12. The test device also includes a reaction frame 3 and two jacks 4. The outer furnace body 1 is composed of four outer walls 1-1 encloses a quadrangular prismatic furnace body, the inner furnace body 2 is composed of two inner walls 2-1 and an inner furnace cover 2-2, the inner furnace body 2 is arranged inside the outer furnace body 1, and the four Eight burners 6 are arranged in the furnace body 1, the fuel supply device 7 and the four to eight burners 6 are respectively connected through the fuel pipe 5, and the fan 9 is respectively connected with the four to eight burners 6 through the weathering pipe 8, so Th...
Example Embodiment
[0010] Specific implementation manner 2: As shown in FIG. 1, the fire resistance test device for measuring a single-layer frame in this embodiment, the reaction frame 3 is composed of two uprights 3-1 and a beam 3-2. The upper ends of the two uprights 3-1 are connected together by a cross beam 3-2, and the lower ends of the two uprights 3-1 are respectively fixedly connected to the ground. With this arrangement, the jack 4 can be installed under the crossbeam 3-2, achieving the purpose of applying load to the test member. The other components and connection relationships are the same as in the first embodiment.
Example Embodiment
[0011] Specific implementation manner 3: Figure 1 and figure 2 As shown, the measuring device 12 of this embodiment is composed of a differential displacement meter 12-1, a high-temperature resistant porcelain tube 12-2, four to eight thermocouples 12-3, a data acquisition instrument 12-4, and a computer 12. -5 composition, one end of the four to eight high-temperature resistant porcelain tubes 12-2 respectively penetrates the outer furnace body 1 and is arranged between the outer furnace body 1 and the inner furnace body 2. One end of 12-2 is respectively connected to the reaction frame 3 through a differential displacement meter 12-1. The four to eight thermocouples 12-1 are arranged between the outer furnace body 1 and the inner furnace body 2. 12-1 is connected to computer 12-3 through data acquisition device 12-2. Such a setting can easily measure the fire resistance limit, temperature field and structural response (deformation, side displacement and support reaction force, ...
