Description
Technical field
It the utility model is related to building engineering field, and in particular to a kind of high intensity refines spiral lamination dowel.
Background technology
The reinforcing bar used at present in architectural engineering is generally single straight line steel bar, dull to have simple in construction, manufacture
The characteristics of easy, but the defects of low poor adhesion between concrete of tensile strength, bond stress deficiency be present, particularly
It is used as high strength anchor bar, template in the large-scale mixed geotechnological journey such as palisades, slope anchorage, large-scale dam, bridge, tunnel, civil buildings
It is outstanding the problem of its bond stress deficiency aobvious to protrude during dowel.
The content of the invention
Deficiency of the purpose of this utility model aiming at above-mentioned technology, there is provided a kind of high intensity refines spiral lamination dowel,
Tensile strength is high, and bond stress is strong, can effectively improve efficiency of construction, and safety guarantee is high.
To achieve the above object, the high intensity designed by the utility model refines spiral lamination dowel, including straightway, also wraps
The bellows segment being connected with described straightway one end is included, the bellows segment includes 1~7 ripple, the straightway and the ripple
Angle a is formed, the scope of the angle is 8 °~30 °.
Preferably, the length of the ripple is 80mm~300mm, and the radius of the ripple is more than 30mm, the ripple
Action 8mm~50mm.
Preferably, the length of the straightway is 40mm~240mm, a diameter of 10mm~40mm of the straightway.
Preferably, the outer surface of the dowel is furnished with T-shaped screw thread.
Preferably, the outer surface of the dowel is furnished with square screw thread.
The utility model compared with prior art, has advantages below：
1st, by setting ripple, tensile strength is high, and bond stress is strong, be adapted to palisades, slope anchorage, large-scale dam, bridge,
Be used as in the large-scale concrete project such as tunnel, civil buildings high strength anchor bar, template dowel, permanent construction it is pre-buried and anchoring；
2nd, efficiency of construction can be effectively improved, and safety guarantee is high.
