Description

TECHNICAL FIELD

[0001] The application relates to the technical field of insulation board detection equipment, and in particular to a sample holder for water absorption rate detection of an insulation board. BACKGROUND

[0002] As an important building material, the building material insulation board is widely used in building engineering. In order to ensure that the quality of the insulation board meets the standard requirements, the water bleeding performance of the insulation board must be comprehensively detected to evaluate the stability and durability of the insulation board in a humid environment, which is of great significance to improve the overall quality and service life of the building.

[0003] The most commonly used method for detecting the water bleeding performance of the existing building material insulation board is the direct immersion method. The direct immersion method is to directly immerse the insulation board sample in water to test the water absorption rate of the insulation board and then analyze and evaluate the water bleeding performance of the insulation board.

[0004] The method can meet the basic detection requirements, but the overall quality of the insulation board is light, and the insulation board is easy to float on the water surface during immersion, thereby affecting the accuracy of the water absorption rate detection data of the insulation board.

[0047] The following will be described in detail Figures 1-3 The present application will be further described in detail.

[0048] The embodiment of the present application discloses a sample holder for detecting water absorption rate of thermal insulation board.

[0049] Reference Figure 1 The sample holder for testing water absorption rate of thermal insulation board comprises a bottom plate 1, four screw rods 2, a hanging plate 3 and a fixing assembly 4. The bottom plate 1 and the hanging plate 3 are horizontally arranged, the four screw rods 2 are threadedly connected to the bottom plate 1 and the hanging plate 3 at two ends respectively, the fixing assembly 4 is installed on the bottom plate 1 and used for fixing the thermal insulation board sample.

[0050] In use, the thermal insulation board sample is placed on the bottom plate 1, and then the thermal insulation board sample is stably fixed on the bottom plate 1 by the fixing assembly 4. Then, the sample holder and the thermal insulation board sample are immersed in the testing water for testing the water absorption rate of the thermal insulation board.

[0051] Reference Figure 1 and Figure 2 The bottom plate 1 and the hanging plate 3 are both cross-shaped and made of non-water-absorbing material, so as to prevent the bottom plate 1 and the hanging plate 3 from absorbing water and affecting the experimental results during the experiment. The bottom plate 1 is provided with rubber pads 8 for preventing the thermal insulation board sample from being scratched or damaged during installation or binding. The hanging plate 3 is fixedly provided with hooks 7 for facilitating the hanging of the sample holder on the testing equipment. The middle section of the screw rod 2 is provided with a scale line 9 for facilitating the control of the water immersion depth of the thermal insulation board sample by the operator.

[0052] Reference Figure 2 and Figure 3 The fixing assembly 4 comprises a binding belt 41 and a motor 42. The binding belt 41 is arranged on the bottom plate 1 and fixedly connected to the bottom plate 1 at one end. The fixed end of the motor 42 is fixedly installed on the bottom of the bottom plate 1, and the output end of the motor 42 is fixedly connected to the other end of the binding belt 41.

[0053] In use, the thermal insulation board sample is placed on the bottom plate 1 at a proper position, and then the motor 42 is started. The output end of the motor 42 starts to rotate, and the other end of the binding belt 41 is pulled. With the rotation of the motor 42, the binding belt 41 is gradually tightened and wound around the thermal insulation board sample and the bottom plate 1 for testing the water absorption rate of the sample. When the water absorption rate test of the sample is completed, the motor 42 is reversed, the output end of the motor 42 reversely rotates, and the binding belt 41 is loosened, thereby completing the fixing task of the sample.

[0054] Reference Figure 2 and Figure 3 The binding belt 41 is uniformly provided with sawteeth 411, and the bottom plate 1 is simultaneously provided with a loosening prevention assembly 5. The loosening prevention assembly 5 comprises a fixed block 51, a clamping block 52 and a spring 53. The fixed block 51 is fixedly installed on the bottom of the bottom plate 1, and a through hole 511 is formed in the fixed block 51. A section of the binding belt 41 close to the motor 42 is arranged through the through hole 511. The clamping block 52 is hingedly connected to the fixed block 51, and one end of the clamping block 52 abuts against the sawteeth 411 of the binding belt 41. The spring 53 is fixedly connected to the fixed block 51 and the clamping block 52 at two ends respectively.

[0055] In use, when the motor 42 starts to tighten the band 41, the band 41 passes through the through hole 511 on the fixed block 51, and as the band 41 is tightened, the sawtooth 411 comes into contact with the clamping block 52, and the clamping block 52 is tightly abutted on the sawtooth 411 of the band 41 under the action of the spring 53. Each time the band 41 is tightened, the clamping block 52 is clamped on the corresponding sawtooth 411, preventing the band 41 from loosening in the opposite direction. During the process of detecting the water absorption rate of the insulation board, the clamping block 52 is always abutted on the sawtooth 411 of the band 41, so that the band 41 will not loosen even if it is slightly shaken or disturbed by the outside world. When the detection is completed and the insulation board sample needs to be disassembled, the clamping block 52 is manually lifted to be separated from the sawtooth 411 of the band 41, the motor 42 reverses the band 41 to loosen it, and the insulation board sample is taken out, thereby ensuring the stability of the sample installation.

[0056] Referring to Figure 2 and Figure 3 , the bottom plate 1 is simultaneously provided with a anti-tightening assembly 6, which comprises a pressure sensor 61, a thimble 62 and a controller 63. The pressure sensor 61 is fixedly installed on the bottom of the bottom plate 1 and is arranged at the place where the band 41 is wound. The thimble 62 is fixedly installed on the pressure sensor 61 and is vertically arranged, with the needle tip of the thimble 62 abutting on the band. The controller 63 is embedded in the bottom plate 1, and the pressure sensor 61 and the motor 42 are both electrically connected with the controller 63.

[0057] In use, when the motor 42 starts to tighten the band 41, the band 41 comes into contact with the thimble 62 as it is gradually tightened, and the thimble 62 applies pressure to the pressure sensor 61. The pressure sensor 61 monitors the pressure of the band 41 in real time and transmits the pressure signal to the controller 63. When the pressure is too large, the controller 63 controls the motor 42 to stop tightening the band 41, preventing the insulation board from being damaged or the water absorption being reduced due to excessive tightening, and improving the accuracy of the insulation board water absorption rate detection experiment.

[0058] The implementation principle of the sample holder for detecting the water absorption rate of the insulation board according to the embodiment of the application is that a stable frame structure is formed by the bottom plate 1, the screw rod 2 and the hanging plate 3, and the length of the screw rod 2 can be adjusted according to different sizes of the insulation board. The motor 42 in the fixing assembly 4 drives the band 41 to tighten, fixing the insulation board sample on the bottom plate 1. The sawtooth 411 on the band 41 cooperates with the anti-loosening assembly 5 to prevent the band 41 from loosening during the detection process.

[0059] The pressure sensor 61 in the anti-tightening assembly 6 monitors the pressure of the band 41 in real time through the thimble 62. When the pressure is too large, the controller 63 controls the motor 42 to stop rotating, protecting the insulation board sample. The bottom plate 1 and the hanging plate 3 are made of a non-water-absorbing material to ensure the detection accuracy, and the rubber pad 8 on the bottom plate 1 prevents the sample from being damaged. The sample holder provides convenience for detecting the water absorption rate of the insulation board and improves the accuracy and efficiency of the detection.

[0060] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, and thus: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
