Abstract
The utility model discloses a refined spiracle steel bar with high strength, which consists of a linear section and a corrugated section. The utility model solves the problems of the prior product of low intensity of resisting pulling, bad agglutinative force with the concrete and deficient gripping power. The utility model has the advantages of high intensity of resisting pulling and strong gripping power and is especially fit for being used as a high-strength anchor rod, a template anchor bar, a split screw etc. in the rock face, the slope anchorage, the large dam, the bridge, the tunnel industry, the civil building and the large concrete project.
Description
Technical field
The utility model relates to the reinforcing bar that a kind of construction work is used, and specifically a kind of high strength is made with extra care the spiral lamination reinforcing bar.
Background technology
At present widely used spiral lamination reinforcing bar is single linear pattern reinforcing bar in the construction work, they have simple in structure, make easy characteristics, but they exist poor adhesion, bond stress defect of insufficient between the low and concrete of tensile strength.When particularly being used as high strength anchor bar, template dowel, Screw arbor with nut at both-ends etc. in crag, slope anchorage, large-scale dam, bridge, tunnel industry and civilian construction and large-scale mixed geotechnological journey, it bonds hypodynamic problem and shows outstanding especially.
Summary of the invention
Goal of the invention of the present utility model is exactly the defective at the said goods, provides the strong high strength of a kind of tensile strength height, bond stress refining spiral lamination reinforcing bar, to remedy the deficiency of existing product.
Goal of the invention of the present utility model is achieved in that it is made up of straightway and bellows segment two parts.Length of straigh line is 40mm-180mm, and bellows segment is made up of 1-4 ripple, and the length of each ripple is 120mm, and the ripple radius is 35mm-180mm, and the angle of slope between straightway and the bellows segment is 10 °-30 °
The utlity model has tensile strength height, advantage that bond stress is strong, be particularly suitable in crag, slope anchorage, large-scale dam, bridge, tunnel industry and civilian construction and large-scale mixed geotechnological journey, being used as uses such as high strength anchor bar, template dowel, Screw arbor with nut at both-ends.
