Two baffles 212 are installed inside the slider 211, and two limit plates 216 are installed on the top of the slider 211. A crossbar 214 is disposed inside the slider 211 and the two partitions 213, and two compression springs 215 are disposed on the crossbar 214; The two limiting plates 216 are each provided with a latch 217, and the latch 217 is adapted to penetrate the interior of the partition 213; The plate distance adjustment mechanism 300 includes a truss assembly 310 disposed in a slider 211 and clamped by two baffles 212; The double-sided pressure-bearing assembly 220 includes a pressure pad 221 mounted on the slider 211. Two vertical grooves 224 are formed inside the pressure pad 221, and two beams 230 are movably mounted in the two vertical grooves 224. A first oblique arm 222 is movably mounted on one of the beams 230, and a second oblique arm 223 is movably mounted on the other beam 230. A tensioning screw 225 is movably mounted in the first oblique arm 222, and the tensioning screw 225 is mounted in a screw hole inside the second oblique arm 223. The plate distance adjustment mechanism 300 is used to provide a suspended support platform for the center of gravity offset assembly 210, and to provide constant and reverse pressure measurement kinetic energy for the two sets of plate surface pressure measurement mechanisms 400; The plate surface pressure measuring mechanism 400 includes an extrusion head 450 for multi-point compression testing of the foam plastic material board 100, a guide tube 420 arranged inside the extrusion head 450, and a liquid booster pad 470 is arranged inside the extrusion head 450. The liquid booster pad 470 is used to perform puncture testing on the foam plastic material board 100 and provide injection kinetic energy for different solutions.
[0026] Since foam plastic boards are mainly used on the main body of buildings, they need to be arranged according to the walls of the buildings according to the requirements of use. During the arrangement process, the workers' installation process, the cleanliness of the walls, the environment and other factors will cause the foam plastic boards to tear. As the boards are stacked higher, the center of gravity of the boards will change. Therefore, under the influence of the above factors, the strength of the boards will be weakened, which will affect the performance of the foam plastic boards.
[0027] The gravity center offset assembly 210 disposed on the beam plate 311 can be used as a sliding platform for the double-sided pressure bearing assembly 220. When the foam plastic material plate 100 is clamped by the two beams 230, the gravity center offset assembly 210 can be selectively moved laterally along the outside of the beam plate 311 by controlling the selective movement of the gravity center offset assembly 210. At this time, the two beams 230 can change the gravity center of the foam plastic material plate 100 under pressure. At the same time, the foam plastic material plate 100 that is positioned and constrained by the propulsion assembly 390 can be subjected to constant pressure and directional compression resistance testing by the two sets of plate surface pressure measuring mechanisms 400 in the state of changing the gravity center. As the two sets of plate surface pressure measuring mechanisms 400 continue to apply pressure, different solutions to be tested that are transferred and sprayed through the guide tube 420 and the extrusion head 450 can be infiltrated into the compressed part of the foam plastic material board 100, and at this time, different solutions can be used to perform anti-corrosion testing at the compressed and deformed part of the foam plastic material board 100; When the guide tube 420 and the extrusion head 450 are idle, the liquid booster pad 470 which is reversely pressurized by the linkage assembly 490 can fall downward. At this time, the pins set in the liquid booster pad 470 will be squeezed out from the micropores of the extrusion head 450, and finally the foam plastic board 100 can be further tested for its puncture resistance.

[0029] Preferably, when the hydraulic component 313 is in operation, its internal hydraulic sub-rod will cooperate with the end 314 to pull the traction plate 315 to effectively extend. At this time, the linkage frame 350 movably installed at the bottom of the traction plate 315 can be compressed and apply constant pressure and directional traction to the two force arms 330. At this time, the through holes opened in the two support frames 320 can provide support for the force arms 330 while ensuring the stability of the bracket 410 when it is pressed and lifted.
[0030] An end head 340 is provided in the middle of the outer side of the beam plate 311, and a linkage frame 350 is movably installed outside the end head 340; The other end of the traction plate 315 is movably mounted on the end rod at the bottom of the linkage frame 350; The plate distance adjustment mechanism 300 further includes two guide members 360, and the two guide members 360 are respectively installed on both ends of the beam plate 311, and two brackets 320 are arranged on the beam plate 311; A force arm 330 is disposed inside the two support frames 320, and a slideway is provided at the outer end of the force arm 330; Two pads 380 are disposed on the inner side of the beam plate 311 , and a horizontally placed propulsion assembly 390 is disposed on the two pads 380 .
[0031] Preferably, the two feet 380 can serve as a supporting platform for the entire propulsion assembly 390. When multi-point compression testing is required on both ends of the foam plastic material board 100, the two guide rods 391 can be controlled to adjust along the slots on the two feet 380. At this time, the foam plastic material board 100 clamped by the side wall clamp 392 can be selectively moved along the bottom of the two sets of board surface pressure measuring mechanisms 400.

At the same time, according to the actual use requirements, the two columns 370 can also be directly fixed on the ground of the site to be tested by concrete. Embodiment 3: Combination Figure 9-11 As shown, based on Example 1, the plate surface pressure measuring mechanism 400 further includes a bracket 410, a flow guide tube 420 is installed in the bracket 410, and a liquid injection joint 430 is provided at one end of the flow guide tube 420; The other end of the flow guide pipe 420 is provided with a plurality of evenly distributed water delivery holes 440 .

When the bottom end of the extrusion head 450 continues to squeeze the foam plastic material board 100, the rubber column head at the bottom of the impact rod 493 can be reversely squeezed by the rest of the foam plastic material board 100, which will eventually cause the extrusion member 492 to drop in the opposite direction, and the liquid booster pad 470 can squeeze the solution in the inner cavity of the extrusion head 450, thereby accelerating the penetration of different solutions into the compressed part of the foam plastic material board 100.

Constrained by the two guide members 360, the two brackets 410 pulled by the two force arms 330 can effectively apply pressure to the plates of different widths.
[0039] The liquid boost pad 470 is composed of a T-shaped end tube, a cylindrical plug, and a plurality of evenly distributed pins; A micro hole is provided in the annular groove at the bottom of the extrusion head 450, and the pin is adapted to fit into the micro hole.
[0040] Preferably, the evenly distributed multiple insertion needles are suitable for the state where no solution is transferred, and the insertion needles through the microholes can further perform the puncture resistance test on the compressed part of the plate.
[0041] Working principle and use process of the present invention: At present, there are also great differences in the application fields of different types of plastic boards, among which foam plastic board is a branch of plastic board, which is mainly divided into polyethylene foam board, polyvinyl chloride foam board and polypropylene foam board; Plastic foam boards are mainly used to protect the main structure of buildings and extend the life of buildings. They can also provide a heat-insulating structural layer for buildings. However, after the foam plastic board is installed on the building, it will be affected by the installation process and the interference of the installation process, and the compressive strength of the board will also change, which will seriously reduce the life of the board; The device is mainly used for tearing resistance detection of simulated variable center of gravity of foam plastic boards used in buildings. When the two columns 370 are fixed on the workbench, the supported truss assembly 310 can provide a sufficiently stable support force for the center of gravity simulation control mechanism 200, and then the combined cushion 240 and the auxiliary pressure plug 250 are removed from the two beams 230, and then the tensioning screw 225 is adjusted until the two beams 230 expand outward, and then the foam plastic board 100 is placed in the gap between the two beams 230; Then, the tensioning screw rod 225 is adjusted again to rotate in the opposite direction until the two beams 230 are pressed against the top and bottom of the foam plastic material plate 100, and then the combined cushion 240 and the auxiliary pressure plug 250 are installed on the two beams 230 after reset, and bolts can be set in the cushion 240, and the cushion 240 is fixed to the beam 230 by using the additional bolts. At this time, the spring 260 will apply a squeezing force to the inner end of the auxiliary pressure plug 250 and the scale 270, and the foam plastic material plate 100 can be pre-pressed and calibrated with the side wall clamp 392; Considering that the foam plastic sheet 100 is subjected to external foreign body pressure after being installed on the building, the two beams 230 can be shifted on the foam plastic sheet 100 until the center of gravity of the foam plastic sheet 100 to be measured matches the center of gravity of the building after assembly, and the two limit plates 216 after movement are fixed by controlling the two latches 217. At this time, the offset slider 211 will drive the double-sided pressure-bearing component 220 to move sideways on the foam plastic sheet 100. Then, the hydraulic component 313 is operated until the hydraulic sub-rod inside it drives the end 314 to move horizontally. After the traction plate 315 is subjected to traction, the linkage frame 350 can be turned sideways with the end 340 as the center. At this time, the two force arms 330 constrained by the two support frames 320 will be subjected to constant traction. Finally, under the calibration limit of the two brackets 410 by the two guide members 360, the outer ends of the brackets 410 will slide along the slideways at the outer ends of the force arms 330. The two brackets 410 with double pressure will press the top of one end of the foam plastic material board 100 and the bottom of the other end. At this time, the bottom end of the extrusion head 450 will be pressurized to perform a tear resistance test on the foam plastic material board 100, and by adjusting the lateral movement of the propulsion component 390 on the two pads 380, the foam plastic material board 100 can simulate the tear resistance test on the building under the state of selectively changing the center of gravity. As the extrusion head 450 continues to pressurize the foam plastic material board 100, the two injection joints 430 can input the solution to be tested into the guide tube 420 and the inner cavity of the extrusion head 450, until the impact rod 493 is pressurized and rises in the opposite direction, the extrusion member 492 will apply a downward thrust to the liquid pressurization pad 470 under the constraint of the positioning plate 491, and the solution in the inner cavity of the extrusion head 450 will be pressurized and sprayed from the micropores at the bottom toward the foam plastic material board 100; This process uses different solutions for testing, so that the actual tear resistance of the foam plastic board 100 after being assembled on the building can be effectively measured.
[0042] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
