Description

Technical Field

[0002] In recent years, building waterproof membranes have been increasingly used in urban rail transit and urban underground spaces. In actual applications, building waterproof membranes will come into contact with some sharp objects such as exposed steel bar heads on the foundation ground. When the waterproof membranes are spread and constructed, the membranes will be stretched and stressed. The contact area between the steel bar heads and other sharp objects and the membranes is small, and the contact area will be deformed by stress. If the puncture strength test of the building waterproof membrane fails, the steel bar heads and other sharp objects will pierce the membranes, causing the membranes to rupture and leak, losing their waterproofing effect.

[0003] At present, the puncture resistance strength test of building waterproof membrane is mainly carried out through the puncture resistance strength device. During the test process, it is necessary to clamp the membrane sample and the puncture resistance clamp by manual compression.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following technical defects that need to be improved:

[0005] When manually compressing building waterproof membranes, uneven force is often applied to different parts, which indirectly affects the accuracy of the puncture resistance test results. In addition, manual compression is time-consuming and labor-intensive, reducing the test efficiency. Utility Model Content
