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.

Embodiment 1

[0032] Embodiment 1: the first kind of waste tire truss, see Figure 1-Figure 4 , a truss formed by two parallel and adjacent top beams 2 and bottom beams 1, and the top beam 2 is an arched structure. The junction of the top beam and the bottom beam is finally fixed in the foundation.

[0033] Vertical tires 3 are fully filled between the roof beams 2 and bottom beams 1 on each side, while horizontal tires 9 are filled between adjacent two roof beams 2 and two adjacent bottom beams 1, and between adjacent two bottom beams 1 Horizontal tires 9 are filled between the vertical tires 3 .

[0034] Between the adjacent vertical tires 3, a transverse steel strand 4 is penetrated laterally and prestressed, and an oblique steel strand one 5 and an oblique steel strand two 6 are penetrated obliquely and prestressed, so that Each vertical tire 3 generates outward tension, sufficient pressure is generated between adjacent vertical tires 3, sufficient pressure is generated between the ve...

Embodiment 2

[0038]Embodiment 2: the second kind of waste tire truss, see Figure 5 and Figure 6 , the content is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that the top beam 2 is a trapezoidal structure.

Embodiment 3

[0039] Embodiment 3: the third kind of waste tire truss, see Figure 7-Figure 9 , the content is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that the top beam 2 is a triangular structure.

Abstract

The invention discloses a waste tire truss, in which vertical tires are fully filled between the top beam and the bottom beam on each side, and steel strands are run through in the horizontal, oblique or vertical direction and prestressed, and the adjacent An inner tensioner is connected to the inner side of the butt joint surface of the waste tire. The invention makes full use of the characteristics of elastic support and long service life of waste tires. The prestressed steel strands provide tension and the waste tires provide internal support. Under the joint action of the tension and support, the structure is very stable and reliable. The internal tensioner is used to increase the internal support force of some waste tires, so as to overcome the change of the internal support force caused by the different aging degrees of waste tires. The invention has a simple structure, so that the waste tires can be directly utilized as a whole, and the processing amount and processing cost are reduced. Improve the recycling efficiency of waste tires and reduce 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...
