Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation board performance detection, and in particular to a building thermal insulation board performance detection device. Background Art

[0002] The insulation board is a rigid foam plastic board made of polystyrene resin as raw material, combined with other raw and auxiliary materials and polymers, which is manufactured by heating and mixing while injecting a catalyst, and then extruding and pressing into shape. It has moisture-proof and waterproof properties, and can reduce the thickness of the building's external envelope structure, thereby increasing the indoor usable area.

[0003] After the insulation board is produced, it needs to undergo a variety of performance tests, including combustion performance test, thermal insulation performance test, and tensile strength test. The tensile strength test of the insulation board can be used to test the bonding strength between the insulation board and the wall, and the tensile strength of the insulation board itself.

[0004] When testing the tensile strength of insulation boards, it is usually after the insulation boards are constructed. Then the staff randomly selects test points on site using a tensile strength tester to perform a tensile strength test. However, due to differences in construction personnel, construction time and construction conditions during the construction of insulation boards, differences in the bonding strength of the insulation boards will occur. When randomly selecting test points, it is inevitable that insulation boards bonded under different conditions will be selected. At this time, it is impossible to determine whether the test results are due to the quality of the insulation boards or the construction reasons, which affects the accuracy of the judgment of the tensile strength of the insulation boards.

The test results obtained in this way are more referenceable.

Compared with the on-site construction affected by the different force applied by the construction workers, the present invention uses uniform force through mechanical rolling, which eliminates the inaccurate test results of the insulation board's anti-pull-out performance caused by bonding factors.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0031] like Figure 1 As shown, a building insulation board performance testing device is used to test the tensile strength of the insulation board, including a base 1, the upper surface of the base 1 is provided with a placement mechanism 5 for bonding to the insulation board, the upper surface of the base 1 is fixedly connected to two left-right symmetrical support frames 4, the performance testing device also includes a driving mechanism 2 for applying tension to the insulation board, the driving mechanism 2 is arranged on the two support frames 4, the performance testing device also includes a connecting mechanism 6 for pressing the insulation board against the placement mechanism 5 and assisting the driving mechanism 2 to perform a tensile strength test, and the connecting mechanism 6 is arranged on the inner side of the support frame 4.

[0032] like Figure 2 As shown, the driving mechanism 2 includes a fixed frame 21 fixedly connected to two support frames 4 , a connecting member 22 is provided on the upper surface of the fixed frame 21 , and a driving member 23 is provided on the fixed frame 21 .

[0033] like Figure 2As shown, the connecting member 22 includes a changing wheel group 223 fixedly connected to the upper surface of the supporting frame 4, a support 222 is fixedly connected to the middle position of the upper surface of the fixed frame 21, a lever 221 is hinged on the inner side of the support 222, and a pull rope 224 is fixedly connected to the left and right ends of the lower surface of the lever 221, and the end of the pull rope 224 away from the lever 221 passes around its corresponding changing wheel group 223 and is fixedly connected to the connecting mechanism 6.

[0034] like Figure 2 As shown, the driving member 23 includes a sliding seat 232 which is slidably connected to the front side of the upper surface of the fixed frame 21, and a hydraulic telescopic cylinder 233 is fixedly connected to the sliding seat 232. A pulling seat 231 is fixedly connected to the telescopic end of the hydraulic telescopic cylinder 233. The pulling seat 231 is provided with a roller which changes the sliding friction between the pulling seat 231 and the lever 221 into rolling friction, and the roller rolls with the upper surface of the lever 221.

[0035] During specific use, first slide the sliding seat 232 on the fixed frame 21 to slide the sliding seat 232 to the left, and then the hydraulic telescopic cylinder 233 contracts to generate downward pressure on the left end of the lever 221 by pulling the seat 231. At this time, the lever 221 rotates on the support 222 to lift its right end upward. At this time, the lever 221 pulls the pull rope 224 at its right end to bypass the changing wheel group 223 to generate tension on the connecting mechanism 6 at the right end, thereby pulling the connecting mechanism 6 upward on the support frame 4.

[0036] It should be noted that when the left end connecting mechanism 6 is needed to perform tensile strength test on the insulation board, the sliding seat 232 is slid to the right end on the fixed frame 21, and then the above steps are repeated to lift the left end connecting mechanism 6 upward.

[0037] like Figure 3 As shown, the placement mechanism 5 includes a connecting groove 51 opened on the upper surface of the base 1, and two left-right symmetrical wall panels 55 are slidably connected inside the connecting groove 51. Two first limit blocks 52 are fixedly connected to the middle position of the inside of the connecting groove 51, and the front and rear surfaces of the opposite ends of the two wall panels 55 are provided with limit ear plates 53. Second limit blocks 54 are provided on the upper surface of the base 1 and between the four limit ear plates 53 and the corresponding support frame 4.

[0038] During specific use, when the connecting mechanism 6 on the left is lifted upward, an insulation board sample is selected and super glue is evenly applied on the bottom, and then placed on the upper surface of the wall panel 55 on the left. The upward pulling force on the connecting mechanism 6 on the left is then canceled by stretching the hydraulic telescopic cylinder 233. After the connecting mechanism 6 on the left is no longer subject to the pulling force, it moves downward.

[0039] It should be noted that after a tensile strength test of the insulation board is carried out on the wall panel 55, the position of the wall panel 55 relative to the connecting mechanism 6 is adjusted by sliding the wall panel 55 inside the connecting groove 51, and the position on the wall panel 55 that has not been tested is adjusted to below the connecting mechanism 6 so that the next test can be carried out quickly. When the wall panel 55 abuts against the first limit block 52, the area of ​​the wall panel 55 directly below the connecting mechanism 6 can be tested once, and when the limit ear plate 53 is in contact with the second limit block 54, the area of ​​the wall panel 55 below the connecting mechanism 6 can also be tested once.

[0040] like Figure 4 As shown, the connecting mechanism 6 includes a rotating member 64 slidably arranged on the supporting frame 4, a connecting member 61 is arranged at the bottom end of the rotating member 64, a plurality of adjusting members 63 are arranged on the connecting member 61, and a plurality of fixing members 62 for connecting with the insulation board are arranged on the adjusting member 63.

[0041] like Figure 4 and Figure 5 As shown, the rotating member 64 includes a plurality of connecting rods 641 that slide up and down and penetrate and are connected to the upper surface of the support frame 4, a connecting spring is sleeved on the vertical section of the connecting rod 641 and is located between the upper surface of the support frame 4 and the horizontal section of the connecting rod 641, the bottom ends of the plurality of connecting rods 641 are commonly fixedly connected to a fixed outer ring 642, the inner circumferential surface of the fixed outer ring 642 is rotatably connected to a rotating inner ring 644, the upper surface of the fixed outer ring 642 is fixedly connected to a cross-shaped limiting bracket 643, and the end of the pull rope 224 away from the lever 221 is fixedly connected to the upper surface of the cross-shaped limiting bracket 643.

[0042] In the initial state, the lever 221 is in a horizontal state, and at this time, the bottom ends of the left and right fixing members 62 are in contact with the upper surface of the wall plate 55 .

[0043] In specific use, after the insulation board is bonded to the wall board 55 and the lever 221 cancels the pulling force on the connecting mechanism 6, the lever 221 pulls the cross-shaped limit bracket 643 upward, and the connecting spring between the connecting rod 641 and the supporting frame 4 is stretched. When the cross-shaped limit bracket 643 is no longer subjected to the pulling force, the cross-shaped limit bracket 643 is pulled downward by the elastic force of the connecting spring. At this time, the fixing member 62 contacts the insulation board placed below it, and the connecting rod 641 is on the supporting frame 4. At this time, the connecting spring is still in a stretched state, and the connecting spring generates a downward thrust on the fixed outer ring 642, which acts on the insulation board through the fixing member 62, and generates downward pressure on the insulation board, so that the connection between the insulation board and the wall panel 55 is more firmly connected. At the same time, the inner ring 644 is rotated on the fixed outer ring 642 to drive the fixing member 62 to make a circular motion on the upper surface of the insulation board, and the insulation board is rolled, so as to reduce the cavity between the insulation board and the wall panel 55, thereby ensuring that the detection result is more accurate.

[0044] like Figure 5 and Figure 6 As shown, the connecting member 61 includes a cross-shaped mounting bracket 612 fixedly connected to the lower surface of the rotating inner ring 644, a connecting column 613 is fixedly connected to the center position of the lower surface of the cross-shaped mounting bracket 612, the bottom end of the connecting column 613 is fixedly connected to a connecting plate 614, and the four bottom ends of the cross-shaped mounting bracket 612 are commonly fixedly connected to a fixing ring 611.

[0045] like Figure 7 As shown, the adjusting member 63 includes a second slide groove 635 opened on the outer circumferential surface of the connecting disk 614 and a first slide groove 632 opened on the inner circumferential surface of the fixing ring 611, and the second slide groove 635 and the first slide groove 632 are slidably connected with a mounting cross bar 633 inside, and a plurality of evenly distributed limiting holes 634 are opened on one side of the mounting cross bar 633, and the two ends of the upper surface of the mounting cross bar 633 are respectively fixedly connected with limiting plates 631, and the upper surface of the limiting plate 631 is provided with fastening bolts.

[0046] like Figure 2 and 7 As shown, the fixing member 62 includes a plurality of connecting seats 624 slidably arranged on the mounting cross bar 633, and a limit pin 627 is elastically slidably connected to the connecting seat 624 for limiting the position of the connecting seat 624 on the adjusting member 63, and the size of the limit hole 634 is adapted to the size of the limit pin 627, and a threaded rod 623 is fixedly connected to the bottom end of the connecting seat 624, and a threaded sleeve 622 is threadedly connected to the bottom end of the threaded rod 623, and a connecting seat 625 is rotatably connected to the circumferential surface of the threaded sleeve 622, and a clamping roller 626 is rotatably connected to the bottom end of the connecting seat 625, and a connecting foot 621 is clamped on the connecting seat 625, and the connecting foot 621 is bonded to the insulation board by strong glue.

[0047] During specific use, when the insulation board is rolled by the fixing member 62, first, according to the detection needs, the position of the connecting seat 624 on the mounting cross bar 633 is adjusted by sliding the connecting seat 624 on the mounting cross bar 633. After the adjustment is completed, the limiting pin 627 is clamped in the limiting hole 634 to limit the connecting seat 624 on the mounting cross bar 633. Then, the above steps are repeated. After the positions of the connecting seats 624 on multiple mounting cross bars 633 are all adjusted, the positions of the mounting cross bars 633 on the connecting disk 614 and the fixing ring 611 are adjusted along the circumferential direction. The distribution state of multiple mounting cross bars 633 is adjusted by sliding the mounting cross bars 633 on the connecting disk 614 and the fixing ring 611. After the distribution state of multiple mounting cross bars 633 is adjusted to the required state, the mounting cross bars 633 are kept relatively fixed with the fixing ring 611 and the connecting disk 614 through the fastening bolts on the limiting plate 631.

[0048] When the position of the installation cross bar 633 is adjusted, when the inner ring 644 rotates, the fixing ring 611 and the connecting plate 614 are driven to rotate synchronously, and the multiple connecting seats 624 are driven to rotate accordingly. At this time, the clamping roller 626 at the bottom end of the connecting seat 624 rotates in contact with the upper surface of the insulation board during the rotation of the connecting seat 624, so as to achieve rolling of the insulation board. After the rolling is completed, the detection point is selected, and the connecting foot 621 is clamped on the connecting seat 625 corresponding to the detection point position. The specific clamping process is: first, the connecting seat 625 is adjusted upward by rotating the threaded sleeve 622 , then evenly apply strong glue to the bottom of the connecting foot 621 and clamp it on the connecting seat 625, then rotate the threaded sleeve 622 in the opposite direction to make the connecting foot 621 close to the upper surface of the insulation board. Then, after standing for a period of time, start the inspection work, the lever 221 is forced to lift upward, and the pull rope 224 bypasses the changing wheel group 223 to generate an upward pulling force on the cross-shaped limiting bracket 643 to perform a pull-out strength test. The staff judges whether the pull-out strength of the insulation board meets the requirements based on the applied pulling force, the degree of damage to the insulation board and the remaining bonding area between the insulation board and the wall panel 55.

[0049] It should be noted that when one end of the lever 221 is lifted upward for testing, after the test is completed, preparations for the next test are carried out. When the preparations for the test are completed, the other end of the lever 221 is lifted upward. At this time, the fallen end can press the insulation board. During the testing work on one side, the preparation work on the other side is completed, thereby improving the efficiency of the testing work.

[0050] Working principle: During specific use, firstly, the fixing part 62 on one side is lifted upwards through the driving mechanism 2. At this time, the connecting spring on the connecting rod 641 is stretched, and then the bottom surface of the selected insulation board test sample is evenly coated with strong glue and bonded to the wall panel 55 under the fixing part 62. At this time, the pulling force generated by the driving mechanism 2 on the fixing part 62 is cancelled, and the fixing part 62 is restored to its original position under the action of the elastic force of the connecting spring itself. Since the insulation board is placed under the fixing part 62, the fixing part 62 cannot be restored to its original position at this time, and the connecting spring remains in a stretched state. At the same time, downward pressure is applied to the insulation board through the fixing part 62, and then the connecting part 61 drives multiple fixing parts 62 to cooperate with the rotating part 64 to rotate in a circular direction on the upper surface of the insulation board, and rolls the upper surface of the insulation board, so that the bonding between the insulation board and the wall panel 55 is more firmly.

[0051] After the rolling operation is completed, the fixings 62 required to be connected to the insulation board are connected to the insulation board through strong glue according to the detection requirements. When the fixings 62 and the insulation board are firmly connected, the pulling force is generated by the driving mechanism 2 until the insulation board is damaged or the insulation board is separated from the wall panel 55. The staff judges whether the tensile strength of the insulation board meets the requirements based on the applied pulling force, the degree of damage to the insulation board and the remaining bonding area between the insulation board and the wall panel 55. When the insulation board is pulled apart as a whole, the greater the degree of damage at the breaking position of the insulation board, the worse the quality of the insulation board itself. When it is pulled apart from the bonding position with the wall, with the same bonding strength, the larger the area of ​​the insulation board leaking out of the wall, the higher the strength of the insulation board itself.
