Abstract
The utility model relates to a metal anchor rod, particularly to an anticorrosion metal anchor rod. The surfaces of a rod body, an anchor head and an anchor plate of the utility model are all provided with anticorrosion layers which can be a zinc plated layer or a copper plated layer or a nickel plated layer. The anticorrosion metal anchor rod can be effectively prevented from rust, and thus the anticorrosion metal anchor rod is ensured to have enough strength for a long time to avoid accidents. The utility model has the advantages of simple structure and low cost, and is suitable for popularization and use in a large range.
Description
The utility model relates to a kind of anchor pole, particularly a kind of Anti-corrosion metal anchoring-bolt.
Along with the deep development of mine support reform, bolt support technology is a dark horse, and the well lane engineering supporting is played a part very important, and part mine bolt support drilling depth reaches more than 90%.Because of the tunnel median year is dark moist, getting rusty of anchor pole is universal phenomenon, and anchor pole gets rusty and must cause anchor rod strength to descend, thereby cause the generation of some contingencies, though the plastics anchor bar that occurs can prevent to get rusty at present, intensity is obviously not as anchor metal, because of almost not using a bit.
The purpose of this utility model will provide a kind of exactly can prevent effectively that anchor pole from getting rusty, and Anti-corrosion metal anchoring-bolt simple in structure, with low cost.
For achieving the above object, the utility model adopts technical scheme as described below: Anti-corrosion metal anchoring-bolt comprises the body of rod, anchor head, anchor dish etc., there is an anticorrosive coat on the surface of anchor pole, this anticorrosive coat can be zinc coat or copper plate or nickel coating, and this anticorrosive coat can pass through hot plating technology, electroplating technology, chemical plating process, spraying coating process realization under the situation of not destroying the strength of materials.
Adopt the Anti-corrosion metal anchoring-bolt of this structure can effectively prevent getting rusty of anchor pole, can guarantee for a long time that anchor pole has enough intensity, thereby stop the generation of some contingencies, this in addition Anti-corrosion metal anchoring-bolt is simple in structure, with low cost, is suitable for large application scope.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the structural representation of pipe-seam type anchor rod.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
With reference to Fig. 1, Fig. 2.Be example explanation the utility model below with the pipe-seam type anchor rod; pipe-seam type anchor rod is to use more common a kind of; it comprises the body of rod 1; anchor head 3; anchor ring 5 and anchor dish 6; on the body of rod 1 and the anchor head 3 pipe seam 2 is arranged; at the body of rod 1; anchor head 3; all there is an anticorrosive coat 4 on the surface of anchor ring 5 and anchor dish 6; the inner surface of its body of rod 1 also has anticorrosive coat; anticorrosive coat 4 can be a zinc coat; copper plate or nickel coating; wherein especially with zinc-plated economical and practical; the anticorrosive coat on anchor pole surface is under the situation of not destroying the strength of materials; can adopt hot dip; electroplate; chemical plating; technologies such as spraying are coated, need to prove that in addition the anchor pole surface coating anticorrosive coat of other kind all drops within the protection domain of the present utility model.
Claims (4)
1, a kind of Anti-corrosion metal anchoring-bolt, it comprises the body of rod (1), anchor head (3), anchor dish (6), it is characterized in that: there is an anticorrosive coat (4) on the surface of anchor pole.
