Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0012] Such as figure 1 with figure 2 Shown, the present invention comprises body 1, and the nominal diameter of described body 1 is 20mm, and described body 1 is hollow cylinder, and the outer surface of described body 1 has several annular projections 2 and four and described annular A continuous raised vertical rib 3 intersected by the protrusions 2, any diameter of the annular protrusion 2 is perpendicular to the direction of the body 1, and the direction of the vertical rib 3 is consistent with the direction of the body 1 . The width of the annular protrusion 2 and the vertical rib 3 is 7 mm. The material of the body 1 is 45Si 2 Cr.

[0013] When in use, due to the adoption of the above-mentioned technical scheme, on the basis of the smooth steel wire, the grip force to cement is increased, and the safety and strength during use are ...

Abstract

A provided novel prestressed steel bar comprises a main body of which the nominal diameter is 16 mm-21 mm, the main body is a hollow column, the external surface of the main body is provided with multiple annular projections and four vertical ribs crossed with the annular projections, any diameter of each annular projection is perpendicular to the direction of the main body, and the direction of each vertical rib is consistent with the direction of the main body. The beneficial effects comprise that by employing the above technical scheme, on the basis of bright steel wires, the bond stress of the steel bar to cement is increased, and the safety and the strength of the steel bar are improved when the steel bar is in use; and also by employing the hollow structure, when the structural strength is guaranteed, raw materials are saved and cost is reduced.

Description

technical field [0001] The invention relates to a novel prestressed steel rod. Background technique [0002] Prestressed steel wire or steel rod has become an important material in the construction of bridges and railways due to its high strength. When using prestressed steel wire, it must ensure the gripping force with cement and other wrappings, so that the prestressed steel wire can be fully utilized during use. role. But the surface of many existing prestressed steel wires or steel rods is smooth, and the holding force is insufficient, which is easy to cause accidents. Contents of the invention [0003] The purpose of the present invention is to provide a new prestressed steel bar with simple structure, safety and reliability. [0004] The technical solution of the present invention is: a new type of prestressed steel rod, including a body, the nominal diameter of which is 16 mm to 21 mm, the body is a hollow cylinder, and the outer surface of the body has several ri...
