Description

Technical Field

[0001] The utility model relates to the technical field of waterproof performance detection devices for waterproof materials, in particular to a waterproof performance detection device for waterproof materials for construction projects. Background Art

[0002] Waterproof membrane is an important structure of buildings. Its purpose is to prevent the penetration of rainwater, snow water and groundwater, and prevent the erosion of moisture, steam and other harmful gases and liquids in the air. Building waterproof materials are a general term for these materials that prevent penetration, leakage and erosion. To detect whether the waterproof material is qualified, professional testing equipment is needed to conduct waterproof testing on it. During the testing process, a waterproof performance testing device for building waterproof membrane testing is needed.

[0003] The existing detection device only performs detection by spraying to simulate rain, which is unable to detect the ultimate failure state of the waterproof membrane, and it is difficult to find the leakage point by spraying for a short time. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the above problems, a waterproof performance detection device for waterproof materials of construction projects is provided, which solves the above problems.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0007] Preferably, a honeycomb hole support net is fixedly provided in the test sample tray, and the honeycomb hole support net is provided with a plurality of evenly spaced through holes. When in use, the waterproof membrane is cut to a suitable size and fixed on the honeycomb hole support net with its waterproof surface facing upward, simulating the environment of the waterproof membrane when it is actually used.

[0008] Preferably, a drain pipe penetrating downward is welded and fixed to the bottom of the water tank, and the drain pipe is used for draining water, so as to facilitate rapid discharge when the detection is completed or the detection water needs to be replaced.

[0009] Preferably, a stop valve is provided in the drain pipe.

[0010] Preferably, a through pressure relief port is provided at the upper end of the water injection cylinder. When the water pump injects water into the water injection cylinder, the sealing rubber plug is located above the pressure relief port but does not separate from the inner cavity of the water injection cylinder. This facilitates water injection. After the water injection is completed, the sealing rubber plug is pushed down by the electric push rod to pass over the pressure relief port, thereby making the inner cavity of the water injection cylinder in a sealed state and increasing the water pressure in the water injection cylinder as the sealing rubber plug continues to descend.

[0011] Preferably, a water pressure gauge is provided at the lower side of the water injection cylinder and connected to its inner cavity for monitoring the water pressure in the water injection cylinder.

[0012] The advantages and positive effects of the utility model are:

[0013] When in use, the waterproof membrane is cut into a circular shape and fixed on the honeycomb hole support net according to the method of use of the waterproof membrane, and then the honeycomb hole support net is sealed to simulate a waterproof sealing state, and then the test sample tray is threaded and sealed to the lower end of the water injection cylinder, and then the water pump is started to add water into the water injection cylinder. After the filling is completed, the electric push rod is started to press down the sealing rubber plug to increase the water pressure in the water injection cylinder. The actual water pressure in the water injection cylinder can be obtained through the water pressure gauge, and the water injection cylinder is made of tempered glass to observe the waterproof ability of the waterproof membrane sample in real time. When the electric push rod is continuously pressed down until the lower end of the test sample tray begins to seep water, it means that the waterproofing fails, and the ultimate pressure resistance of the waterproof membrane can be detected. Compared with the traditional spray waterproof test, the test performed by this device can be closer to the scene during the actual use of the waterproof membrane. BRIEF DESCRIPTION OF THE DRAWINGS
