Abstract

The invention relates to a jip and bursting test device for bursting testing of a coated fabric membrane material, and belongs to the field of membrane structure engineering. The technical problem that in the prior art, a membrane material test specimen slips in a jip, a bursting device has higher cost and is not suitable for coated fabric are solved. The jip for the bursting testing of the coatedfabric membrane material comprises a first fixing part, a second fixing part, a third fixing part and a jip bracket. The second fixing part is arranged on the jip bracket and is movably connected with the jip bracket, and the first fixing part is arranged above the second fixing part. A membrane test specimen is arranged between the first fixing part and the second fixing part, and the third fixing part is arranged on the side faces of the first fixing part and the second fixing part. A concave and convex groove structure is formed between the first fixing part and the second fixing part. Thejip and bursting test device for the bursting testing of the coated fabric membrane material can be used for testing the mechanical properties of the coated fabric and provide a reference basis for the bursting breaking design of a coated fabric membrane structure.

Description

technical field [0001] The invention relates to the technical field of membrane structure engineering, in particular to a fixture and a bursting device for bursting tests of coated fabric membranes. Background technique [0002] Membrane structure is a kind of space structure that is made of a variety of high-strength film materials and reinforcing components to generate a certain pre-tensioning stress inside to form a certain space shape, as a covering structure, and can withstand certain external loads. [0003] In the existing technology, the membrane structure is exposed to the outside world for a long time and is inevitably subjected to various loads, which causes certain deformation or defects in the membrane material. Under the action of the membrane surface tension, defects such as mesoscopic cracks will expand. , resulting in local damage or even overall damage to the membrane structure. Textiles and other materials are mostly non-coated fabrics, which have low den...
