A kind of spiral tight hoop type fixture for bamboo tensile test and its application method

Abstract

The present invention is a spiral clamp type clamp for tensile test of bamboo and its use method, wherein, the upper end of the rotating shell in the circumferential direction is provided with a rotating groove, and the middle and lower end of the rotating shell in the circumferential direction is provided with a number of corresponding movable jaws. The matching movable jaws move the guide rail; the rotating disc is set in the inner rotating shell, and the rotating disc and the rotating shell can rotate relatively through the rotating groove; the conical thread is fixed on the inner side of the rotating shell, and one end of each movable jaw is telescopic The other end is the protruding end. The protruding ends of several movable jaws are set in the corresponding moving guide rails of the movable jaws. Cooperate with the moving guide rail of the movable jaws; the clamping part is fixed on the upper end surface of the rotating disk; when in use, the bamboo to be tested is socketed in the cylindrical structure, and the protruding end of the clamping part is fixed on the tensile testing machine. The invention has the advantages of simple structure, convenient operation and strong practicability.

Description

technical field [0001] The invention relates to a clamp and a using method thereof, in particular to a spiral-tight hoop-type clamp for a bamboo tensile test and a using method thereof. Background technique [0002] With the continuous development of society, buildings made of bricks and concrete have risen in large areas in cities and villages, but the rise of these buildings is based on high energy consumption and high pollution, which has caused great harm to the environment. In recent years, with the continuous enhancement of people's awareness of environmental protection, the concept of energy conservation and environmental protection has been deeply rooted in the hearts of the people. If bricks and concrete can be replaced as materials for making houses or objects, it has become the development direction of society. Due to its fast growth and easy recycling after dismantling, bamboo has been vigorously developed in recent years. However, according to the variety and ag...

Problems solved by technology

The reasons may be as follows: firstly, the diameter of the original bamboo is relatively large, and there is no suitable tensile equipment to clamp the original bamboo directly for testing; secondly, the diameter of the original bamboo varies unevenly, sometimes in an elliptical shape, and there is no unified test The device is ready for operation
