Description

Technical Field

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

[0002] Water permeability testing of building materials is a test that evaluates the ability of building materials to penetrate water, which is crucial to the waterproof performance of buildings. The water permeability of building materials directly affects the waterproof performance of buildings. If building materials do not have good water permeability, it may cause problems such as leakage and seepage in the building, which in turn may cause a series of problems such as wall mildew and structural corrosion. In severe cases, it may even cause the building to collapse, threatening people's lives and property safety.

[0003] After searching, a Chinese patent document with publication number CN218524539U discloses a device for detecting the water resistance of building materials. The patent provides a device for detecting the water resistance of building materials with high efficiency and low work intensity. The patent includes a base, a material discharging frame and a support rod, etc. The middle part of the upper side of the base is provided with a material discharging frame, and the front and rear sides of the upper part of the base are provided with support rods, and the left and right sides of the two support rods are slidably connected with sliding rods.

[0004] This patent starts a water pump, which then extracts the incoming water. The water flowing to the three sprinkler heads can then be sprayed on the building materials. The water at the three sprinkler heads can be used to test the waterproofness of the building materials. In this way, the waterproofness of the building materials can be tested, thereby improving the efficiency of people's testing of the waterproofness of building materials.

[0005] However, the above invention has the following shortcomings: the above patent directly tests the waterproofness of the building materials below by setting up multiple nozzles. This method will cause the phenomenon of the waterproof test to be not obvious enough, and it is not convenient for quick observation and judgment. It takes a certain amount of time to conduct waterproof identification of the building materials after the test; at the same time, since the building materials are set below the nozzles, the water can easily flow randomly under the action of gravity, and the water will splash, affecting the reliability of the test results, so there are limitations.
