In embodiment of the present utility model, more specifically, this fire protecting performance proving installation also comprises infrared temperature-measuring gun 5, and described infrared temperature-measuring gun 5 is located at support 4 one sides, and the temperature sensing position of described infrared temperature-measuring gun 5 is right against between two clips and is provided with gap.In addition, this fire protecting performance proving installation also comprises timer.
In the utility model embodiment, because horizontal iron chi is not subject to the effect of other external force, be only own wt, therefore for convenience of dismounting, and do not affect the horizontal positioned of electric furnace, more specifically, described surveyor's staff 3 is fixed on the platform of lifting table 1 by metal double-side glue.
In embodiments of the present invention, it is 220V that electrothermal furnace 2 is selected rated voltage, and rated power is 2500W, and rated temperature is the laboratory electric furnace of 1100 ℃.
Support 4 is chosen the iron stand of the common casting pig material in laboratory as sample holder, and wherein, base 41 is of a size of 210 * 135mm, is cast iron manufacture, and weight is 1.5kg, can guarantee that selected sample holder is reliable and stable; Montant 42 diameters are 12mm, high 60mm, and there is M10 * 18mm screw thread one end; Dull and stereotyped folder 43 bar footpaths are 8mm, and length is 180mm, the closed gap L EssT.LTssT.LT of clip 0.1mm, and butterfly nut is M5.
During the selection of infrared temperature-measuring gun 5, because big panel method is to take that the time of sample unexposed surface temperature when reaching 220 ℃ or test specimen and carrying on the back fiery face and occur penetrating is final experimental result, therefore measure temperature in time, accurately, be related to the accuracy of test findings.And in test, need to control intensification by adjusting specimen height, the temperature that needs continuous test sample coat side, therefore, in device design process, need frequently to measure temperature, for convenience of, thermometric fast and accurately, the utility model selects hand-held, non-contacting infrared line temperature measurer to carry out temperature survey, its temperature-measuring range-18 ℃～1500 ℃, 0.1 ℃ of measuring accuracy.
Timer is selected the existing general manual time-keeping in laboratory, when temperature reaches after 220 ℃, stops immediately stopwatch, timing.
Above-mentioned each parts are assembled after choosing, and the basic step of assembling is:
1, by the conventional method in day-to-day test, support 4 is in place;
2, with metal double-side glue, the surveyor's staff of one level 3 (iron chi) is fixed on to lifting table 1 bottom surface, then lifting table 1 is raised up to certain altitude, with the adjustment height that facilitates later stage or liter or fall;
3, electrothermal furnace 2 is placed on lifting table 1;
4, pair of brackets 4 is placed in respectively to electrothermal furnace 2 the right and lefts, distance is advisable to facilitate test, sample carrier not to contact electric furnace;
5, infrared temperature-measuring gun 5 (infrared thermometer), timer (stopwatch) are taken out, to facilitate follow-up thermometric and timing.
In actual application of the present utility model, after experiment starts, press timer (stopwatch), be placed on experiment table, with infrared temperature-measuring gun 5, measure sample back temperature at set intervals, when test has just started, thermometric interval can be elongated a little, when back temperature to be tested approaches 220 ℃, pick up stopwatch, prepare writing time at any time.Because the thermometric speed of infrared temperature-measuring gun 5 is fast, only need 2～3 seconds, therefore, and in test teaching, completely can be by the operation of single finishing device.Operate concrete mode as follows:
