Description

Technical Field

[0001] The present invention relates to the technical field of evaluating the fire resistance performance of building components, and particularly to a method for testing the resistance of building components to water spray impact, a device for testing the resistance of building components to water spray impact, an electronic device, and a computer-readable medium. Background Art

[0002] Fire resistance performance is an important performance of building components. Good fire resistance performance can enable building components to maintain their structural functions in a fire, and can also confine the fire within a certain space, ensuring the fire safety of buildings. However, building components will be damaged under the action of external forces such as collapsed furniture or other heavy objects and the water column of a fire hose during fire extinguishing in an actual fire, causing the building components to lose their original functions, thereby enabling the fire to spread rapidly. In this case, it is necessary to consider the test of the water spray impact performance of building components immediately after the fire resistance test. Currently, some building components such as fire doors, fire windows, and fireproof sealing materials used in key positions are required to conduct water spray impact performance tests immediately after the fire resistance limit test.

[0003] The national standard GB / T26784-2011 describes the path of water spray impact as follows: "The water spray impact first acts on the bottom of the fire-exposed surface of the specimen, and then acts on all other parts, slowly changing the direction so that the water impact moves inside the outer perimeter of the specimen, without concentrated impact, stopping at any point on the specimen, or randomly changing the direction. Within 310 mm of the outer perimeter of the specimen, the direction of the water impact can be changed in the following ways: a) Impact along the perimeter of the specimen, starting from any bottom corner of the specimen and moving upward. b) After the water flow covers the perimeter of the specimen, make the water flow move vertically, and impact at intervals of 305 mm until the entire width direction is impacted. c) Subsequently, make the water flow move horizontally, and impact at intervals of 305 mm until the entire height direction is covered. If the specified impact time has not been reached, repeat in the reverse steps." Although the standard describes the method of water spray impact, it does not provide a detailed description of the specific water spray impact path, nor does it mention the path coordinate calculation method.

[0004] Chinese Patent Application CN202310965772.8 proposes a method and device for testing the resistance to water spray impact. Using an automated control logic, after the test starts, no manual intervention is required. The test device automatically determines the data of building separation components, formulates the water spray impact path, and automatically drives each execution unit, enabling the water spray impact test to be fully automated. The method and device for testing the resistance to water spray impact provided by the present invention can completely eliminate the differences in manual operations and personnel safety, and ensure the accuracy of specimen verification.

[0005] Although the method of this patent application mentions that the test device automatically formulates the route of water spray impact, it does not mention the specific water spray impact path, nor does it mention the method of calculating path coordinates. Its disadvantages are mainly reflected in the following aspects: (1) The prior art does not mention the specific trajectory of the water impact path, so that there is no unified water impact path when performing water impact tests between different laboratories or among different personnel. It is possible that the same sample may have different water impact paths in different tests, resulting in different test results. (2) The prior art does not mention the method of calculating path coordinates, making it impossible to conduct a fully automatic water spray impact test. Summary of the Invention

[0021] The following will introduce the method for testing the resistance of building components to water spraying impact of the present invention in detail: 1. A water impact path for testing the resistance of building components to water spraying impact The water impact path is identified by the impact points of the water spray column on the surface of the sample to be measured as feature points, and the straight line between two consecutive feature points.

[0022] According to the different numbers of water impacts in the vertical and horizontal movement directions inside the surface of the sample to be measured in the water impact path, it is divided into four different test water impact paths, as follows. Among them: NV is the total number of internal water impacts in the vertical movement direction, excluding 2 times of door frame impacts; NH is the total number of internal water impacts in the horizontal movement direction, excluding 2 times of door frame impacts.

[0023] (1) When NV is odd and NH is odd, the water impact path is as follows Taking a sample with a size of 1100mm * 2300mm as an example to draw the water impact path, the water impact feature points of the first six points, Pre point, P1 point (Point A), P2 point (Point B), P3 point (Point C), P4 point (Point D), P5 point, and the path are as Figure 2 shown.

[0024] 1) The feature points and path of the first cycle are as Figure 3 ; 2) Since the first cycle returns to Point A and each subsequent cycle is exactly the same, the coordinates of the feature points in several subsequent cycles are exactly the same as those of the feature points in the first cycle.

[0025] In the first path mode, the coordinate sequence of feature points in each cycle is the same, and the water spraying path starts from the bottom corner of the sample to be measured and moves upward. After completing the vertical direction impact, it impacts at intervals along the horizontal direction until the entire surface of the sample is covered.

[0026] (2) When NV is odd and NH is even, the water impact path is as follows Taking a sample with a size of 1000mm * 2000mm as an example to draw the water impact path, the water impact feature points of the first six points, Pre point, P1 point (Point A), P2 point (Point B), P3 point (Point C), P4 point (Point D), P5 point, and the path are as Figure 4 shown.

[0027] 1) The characteristic points and path of the first cycle are as Figure 5 ; 2) After the first cycle, return to point D. The path of the second cycle is different from that of the first cycle and needs to be recalculated. The characteristic points and path of the second cycle are as Figure 6 ; 3) After the second cycle, return to point A. The path of the third cycle is the same as that of the first cycle, and copy the path of the first cycle; after the third cycle, return to point D. The path of the fourth cycle is the same as that of the second cycle, and copy the path of the second cycle; and so on.

[0028] In the second path mode, the characteristic point coordinate sequences of odd cycles and even cycles change alternately. After completing an odd cycle, adjust the impact direction and perform an even cycle, and subsequent cycles repeat according to the alternating mode.

[0029] (3) When NV is even and NH is odd, the water impact path is as follows Taking a sample with a size of 800mm * 2300mm as an example to draw the water impact path, the water impact characteristic points of the first six points, Pre point, P1 point (point A), P2 point (point B), P3 point (point C), P4 point (point D), P5 point, and the path are as Figure 7 shown.

[0030] 1) The characteristic points and path of the first cycle are as Figure 8 ; 2) After the first cycle, return to point B. The path of the second cycle is different from that of the first cycle and needs to be recalculated. The characteristic points and path of the second cycle are as Figure 9 ; 3) After the second cycle, return to point A. The path of the third cycle is the same as that of the first cycle, and copy the path of the first cycle; after the third cycle, return to point B. The path of the fourth cycle is the same as that of the second cycle, and copy the path of the second cycle; and so on.

[0031] In the third path mode, the characteristic point coordinate sequences of odd cycles and even cycles change alternately. After completing an odd cycle, adjust the impact direction and perform an even cycle, and subsequent cycles repeat according to the alternating mode.

[0032] (4) When NV is even and NH is even, the water impact path is as follows Taking a sample with a size of 800mm * 2000mm as an example to draw the water impact path, the water impact characteristic points of the first six points, Pre point, P1 point (point A), P2 point (point B), P3 point (point C), P4 point (point D), P5 point, and the path are as Figure 10 shown.

[0033] 1) The characteristic points and path of the first cycle are as Figure 11 ; 2) After the first cycle, return to point C. The path of the second cycle is different from that of the first cycle and needs to be recalculated. The characteristic points and path of the second cycle are as Figure 12 ; 3) After the second cycle, return to point A. The path of the third cycle is the same as that of the first cycle, and the path of the first cycle is copied; after the third cycle, return to point C. The path of the fourth cycle is the same as that of the second cycle, and the path of the second cycle is copied; and so on.

[0034] In the fourth path pattern, the coordinate sequences of the characteristic points of odd cycles and even cycles change alternately. After completing an odd cycle, the impact direction is adjusted to perform an even cycle, and subsequent cycles are repeated according to the alternating pattern.

The pressure adjustment point is Pre. P(N)x represents the x-value of the coordinate of the Nth water impact characteristic point; P(N)y represents the y-value of the coordinate of the Nth water impact characteristic point.

[0042] The coordinate ratios of the corresponding plane are as follows: P1x = Cx + SW / 2, P1y = Cy - SH / 2; P2x = Cx + SW / 2, P2y = Cy + SH / 2; P3x = Cx - SW / 2, P3y = Cy + SH / 2; P4x = Cx - SW / 2, P4y = Cy - SH / 2; Prex = Cx + SW / 2, Prey = -1.6.

[0043] NV is the total number of internal water impacts in the vertical movement direction, excluding 2 impacts on the door frame, unit: times; When SW - 0.305 * int(SW / 0.305) = 0, then NV = SW / 0.305 - 1; When SW - 0.305 * int(SW / 0.305) > 0, then NV = int(SW / 0.305); NVt represents the number of internal water impacts in the vertical movement direction that have been carried out, unit: times, and the initial value of NVt is 1.

[0048] (4)The calculation of the flushing path is carried out according to the following process, referring to Figure 15 The specific calculation process is as follows: 1) Coordinate calculation method for each feature point in the first cycle From NVt = 1 to NVt = NV, P(3 + 2 * NVt)x = P(4 + 2 * NVt)x = Cx + SW / 2 - 0.305 * NVt P(3 + 2 * NVt)y = Cy + (SH / 2) * (-1) NVt P(4 + 2 * NVt)y = Cy - (SH / 2) * (-1) NVt P(5 + 2 * NV)x = Cx - SW / 2 P(5 + 2 * NV)y = Cy - (SH / 2) * (-1) NV From NHt = 1 to NHt = NH, P(4 + 2 * NV + 2 * NHt)y = P(5 + 2 * NV + 2 * NHt)y = Cy - (SH / 2 - 0.305 * NHt) * (-1) NV P(4 + 2 * NV + 2 * NHt)x = Cx + (SW / 2) * (-1) NHt P(5 + 2 * NV + 2 * NHt)x = Cx - (SW / 2) * (-1) NHt P(4 + CPN)x = Cx - (SW / 2) * (-1) NH P(4 + CPN)y = Cy + (SH / 2) * (-1) NV If there is only one-cycle impact of water flushing, then P(5 + CPN * CycleN)x = Prex P(5 + CPN * CycleN)y = Prey After that, the calculation ends.

[0049] 2) Coordinate calculation method for each feature point in the second cycle From NVt = 1 to NVt = NV, P(4 + CPN + NVt)x = P(5 + CPN + NVt)x = Cx - (SW / 2 - 0.305 * NVt) * (-1) NH P(4 + CPN + NVt)y = Cy - (SH / 2) * (-1)^NVt * (-1) NV P(5 + CPN + NVt)y = Cy + (SH / 2) * (-1)^NVt * (-1) NV P(5 + 2 * NV + CPN)x = Cx - (SW / 2) * (-1) NH P(5 + 2 * NV)y = Cy + SH / 2 From NHt = 1 to NHt = NH, P(4 + CPN + 2 * NV + 2 * NHt)y = P(5 + CPN + 2 * NV + 2 * NHt)y = Cy + SH / 2 - 0.305 * NHt P(4 + CPN + 2 * NV + 2 * NHt)x = Cx - (SW / 2) * (-1) NHt P(5 + CPN + 2 * NV + 2 * NHt)x = Cx + (SW / 2) * (-1) NHt P(4 + 2CPN)x = Cx + SW / 2 P(4 + 2CPN)y = Cy - SH / 2 If the water impact is only the secondary cycle impact, then P(5 + CPN * CycleN)x = Prex P(5 + CPN * CycleN)y = Prey Then the calculation ends.

[0050] 5) Calculation method for the coordinate of each characteristic point in the third cycle and subsequent cycles From N = 1 to N = CPN When the cycle number is odd, P(4 + CPN * (CycleT - 1) + N)x = P(4 + N)x P(4 + CPN * (CycleT - 1) + N)y = P(4 + N)y When the cycle number is even, P(4 + CPN * (CycleT - 1) + N)x = P(4 + CPN + N)x P(4 + CPN * (CycleT - 1) + N)y = P(4 + CPN + N)y After all the cycles end, then: P(5 + CPN * CycleN)x = Prex P(5 + CPN * CycleN)y = Prey The calculation is then completed.

[0051] Compared with the prior art, the present invention mainly has the following two advantages: (1) The present invention proposes a water spray impact path trajectory diagram for samples of different specifications and sizes during the water impact test, which can unify the practice and reduce the deviation of test results in different tests.

[0052] (2) The present invention proposes a calculation method for the coordinates of different characteristic points of the water impact path. When using devices such as robotic arms and automatic water spray systems, the precise position of the water impact point at different times can be calculated according to this method, so as to realize a fully automatic water spray impact test and reduce the deviation caused during the manual test process.
