Description

Technical Field

[0001] The utility model relates to the technical field of crack prevention cloth detection equipment, in particular to a detection equipment for anti-tensile of crack prevention cloth. Background Technique

[0002] The crack prevention cloth is a composite geotechnical material, mainly used to prevent reflection cracks, water damage and enhance the bearing capacity of the road surface during the construction and renovation of asphalt pavements. It is made of a mixture of glass fiber and polyester. This unique combination combines the strength of glass fiber and the flexibility of polyester fiber. By absorbing asphalt materials, a structural layer is formed, which has physical properties of waterproof, heat-resistant and corrosion-resistant. During the production process, it is necessary to conduct anti-tensile detection on the crack prevention cloth to test its strength.

[0003] In this regard, the Chinese utility model patent with the authorization announcement number of CN220650259U discloses a tensile resistance detection device for a new type of membrane material, belonging to the technical field of membrane material testing. It includes a support frame. Inside the support frame, a movable frame and a fixed frame are respectively arranged from top to bottom. On both sides of the inner cavities of the fixed frame and the movable frame, a rotating shaft is rotatably connected through a bearing. On the opposite side of the rotating shaft, a winding roller is fixed. Through the winding roller, the membrane body to be tested is wound and collected. This can avoid cutting the membrane body to be tested when it is stretched. At the same time, the stretching direction of the membrane body to be tested is consistent with the extending direction of the membrane body to be tested, which can ensure that the force detected by the tensile force measuring device belongs to the force acting on the membrane body to be tested, and can accurately detect the change of the tensile force when the membrane body to be tested is stretched. Since the winding roller is fixed by the self-winding of the membrane body to be tested, it can ensure that the membrane body to be tested is evenly stressed when it is stretched, so that the measured data result is a real data.

[0004] The surface of the crack prevention cloth is flat and smooth. When performing anti-tensile detection by fixing, it may fall off and affect the detection result. For this reason, we propose a detection equipment for anti-tensile of crack prevention cloth to solve the above problems. Content of the Utility Model
