Description

Technical Field

[0001] The invention relates to the technical field of waterproof material permeability detection, and in particular to a building waterproof material permeability detection device. Background Art

[0002] Waterproof materials are a common type of material in the construction field. Waterproof materials are used on the surface of buildings and in some locations where leakage and seepage are more likely to occur, in order to prevent leakage and seepage from occurring in the building, thereby ensuring that the main structure of the building will not be damaged due to seepage, and at the same time ensuring that there will be no leakage and seepage problems inside the building that affect people's living experience.

[0003] Silicone waterproofing agent is a commonly used waterproofing agent. During use, it is necessary to apply the silicone waterproofing agent to the outer surface of building components to form a waterproof coating, so as to prevent water such as rainwater or pipe leakage from penetrating through the building components and entering the interior of the building. In order to ensure that the waterproof coating has sufficient anti-penetration performance, it is necessary to carry out anti-penetration testing on the building components coated with the waterproofing agent coating to determine the anti-penetration parameters of the waterproof material.

[0004] The Chinese invention patent with patent invention number CN202223450992.7 records a building waterproof material permeability detection device, which can divert and collect water that has passed through the waterproof material into a measuring cylinder through the inclined bottom plate and the drainage trough shell, and then count through the timer. When the set time is reached, the controller in the control box can start the electric telescopic rod to drive the sliding seat to slide along the guide groove to ensure that the measuring cylinder is moved away from the end of the drainage trough shell. In this way, the purpose of collecting the infiltrated water at a regular time can be achieved, which is convenient for more accurate comparison when testing the permeability of various waterproof materials. However, in the above-mentioned detection device, when the infiltrated water is diverted by the inclined bottom plate and the drainage trough shell, the water is likely to remain on the surface of the inclined bottom plate and the drainage trough shell, and a certain amount of evaporation occurs. This results in a large measurement error when the infiltrated water is small, which seriously reduces the accuracy of the test results. Summary of the invention
