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.
The various methods of chemically processing waste rubber are not satisfactory. Part of the scheme of using physical methods to process waste tires is to cut and crush them. This kind of recovery rate is low in efficiency, high in cost, and narrow in application fields.

Embodiment 1

[0020] Embodiment 1: A kind of scrap tire prestressed ring assembly, see figure 1 , composed of a plurality of scrap wheels 1 to form a ring structure, and each scrap tire 1 is penetrated with an outer steel strand 2 and an inner steel strand 3 and prestressed respectively, wherein the inner steel strand 3 is prestressed The stress intensity is greater than the prestress intensity of the outer steel strand 2. Each tire is deformed due to mutual extrusion.

Embodiment 2

[0021] Embodiment 2: On the basis of Embodiment 1, an inner tensioner 7 is connected to the inner side of the adjoining surfaces of adjacent waste tires 1 . see figure 2 , the inner tensioner 7 is threadedly connected with a push rod at both ends of a central adjusting screw sleeve, the threads on both sides are reverse threads, the ends of the push rods on both sides are respectively provided with top feet, and the top feet on both sides are provided with Through-holes for steel strands.

[0022] Examples 3 and 4: see respectively image 3 and Figure 4 After the multi-layer prestressed ring assembly is superimposed up and down, the axial steel strand 4 is penetrated and fixed and prestressed to form a prestressed ring three-dimensional structure. image 3 It is a consistent superposition structure up and down, Figure 4 It is a downward dislocation superposition structure.

Embodiment 5

[0023] Embodiment 5: On the basis of Embodiment 1 or Embodiment 2, in order to prevent the single-layer circular ring assembly from being bent and up and down during the pulling process of the annular prestressed steel strand, a There is a shaped part 6 for keeping adjacent waste tires from being dislocated up and down. see Figure 5 , The shaped part includes upper and lower panels 61 and webs 62, and fixing holes 63 are respectively arranged on the upper and lower panels. Be fixed on the side of waste tire 1 by bolt or rivet in the fixing hole 63 .

Abstract

The invention discloses a prestressed circular ring assembly of waste tires, in which a plurality of waste tires are surrounded to form a ring structure, and an outer steel strand and an inner steel strand run through each waste tire and prestressed respectively, wherein The prestressed strength of the inner steel strand is greater than the prestressed strength of the outer steel strand. An inner tensioner may also be connected to the inner side of the butt joint surface of adjacent waste tires. The invention makes full use of the characteristics of elastic support and long service life of waste tires, the prestressed steel strands provide tensile force, the waste tires provide internal support force, and the structure is very stable and reliable. With the help of high strength and toughness and long service life of waste tires, it can be used as the basic unit of building facilities, so that buildings also have due strength and toughness. 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 prestressed circular ring assembly composed of waste tire monomers. 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 waste tires for high-pollution treatment...
