Waste and old tyre truss

Abstract

The invention discloses a waste and old tyre truss. A space between a top beam and a bottom girder at each side is fully filled with vertical tyres, steel strands go through along a transverse direction, an inclined direction or a vertical direction, pre-stress is applied to the steel strands, and inner sides of butt joint surfaces of adjacent the waste and old tyres are connected to inner tighteners. The waste and old tyre truss fully utilizes the waste and old tyre characteristics of flexible support and long service life, the pre-stressed steel strands provide pulling forces, the waste and old tyres provide inner support forces and under the synergism of the pulling forces and the support forces, the structure is very stable and reliable. The inner tighteners improve the inner support forces of a part of the waste and old tyres thereby avoiding inner support force change caused by different aging degrees of the waste and old tyres. The waste and old tyre truss has a simple structure, realizes direct utilization of whole waste and old tyres, reduces a processing amount and a processing cost, improves waste and old tyre recovery utilization efficiency and reduces environmental pollution.

Description

technical field [0001] The invention relates to the technical field of waste tire recycling, in particular to a truss that uses waste tires, steel frames and prestressed steel strands to form an overall stable structure. Background technique [0002] With the rapid development of my country's automobile industry, the number of waste tires continues to rise, and the number of waste tires produced in China is increasing at a rate of 8% to 10% every year. In 2007, there were about 160 million waste tires in my country. In 2010, the production of waste tires in China reached about 250 million, and the recycling rate was only about 50%, which was less than 30% of that in western developed countries. These tires not only pollute the environment, but also waste resources, so the disposal of waste tires has become a serious social problem. It is often seen that waste tires are piled up like mountains. In general, some tires can be retreaded and then reused. But more is to recycle...

AI Technical Summary

Problems solved by technology

[0006] However, for the disposal of waste tires, so far there is no method that fully meets the requirements of environmental protection, energy saving, high efficiency and low cost.

Various methods of chemically treating waste rubber are not satisfactory. At present, some patents provide solutions for using waste tires in physical methods, such as using waste tires as a buffer layer on the surface of guardrails to overcome the complex structure of mechanical buffer structures such as springs. , high cost, not conducive to popularization and use

However, this method only passively utilizes the toughness characteristics of waste tires, and does not make full use of the mechanical properties of waste tires such as elasticity and support.
