Abstract
A wedge-type anchor bar comprises a bar body and a wedge body, wherein the head of the bar body which is made from steel pipes is provided with a spreading slot, a tray and the wedge body is fixedly connected with the bar body by insertion through the spreading slot, and the flatly-triangular tail part of the bar body is provided with a necked-in section. With the utility model, the drilling diameter can be decreased, the drilling speed can be improved, the consumption of anchoring agent can be reduced, and the assemblage and usage costs of the anchor bar can be remarkably decreased. The utility model can satisfy the requirements of high production and high efficiency in the construction of tunnels and laneways.
Description
Technical field
The utility model relates to a kind of anchor pole that tunnel, tunnel support are used that is used for, and particularly is suitable for coal mine roadway, the wedge-type anchor pole that railway, highway tunnel supporting are used.
Background technology
At present, the low anchored force anchor pole that two lateral walls such as domestic coal mine roadway and railway, highway tunnel use mostly is round steel to make a headband screw, the anchor pole of another headband twisted shape.Also has a kind of pipe-seam type anchor rod that is formed from strip steel.There is different defectives separately in these two kinds of anchor poles, show: the processing technology complexity of twisted shape anchor pole, and the diameter of its afterbody fried dough twist is bigger, and bore diameter is also big, and the consumption of anchoring agent is also big in the work, contaminated environment, the high installation rate of processing cost is low.Pipe-seam type anchor rod is reinforced country rock by the swollen tension of elasticity of metal material, as runs into metal material quality instability, the body of rod and aperture size do not match or the down-hole trickle excessive, the body of rod is corrosion very easily, causes supporting to fail.It adopts alloy steel manufacturing, cost of raw material height, and processing technology complexity, support cost height in addition.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of super quality and competitive price are provided, and is simple in structure, adopts wedge locking, realizes the smokeless wedge-type anchor pole of using for roadway support of producing.
The purpose of this utility model is achieved in that and comprises the body of rod, wedge, its structural feature is: the body of rod head made from steel pipe has the spreading seam, and pallet, wedge are pegged graft with the body of rod by the spreading seam and are fixed together, the afterbody of the body of rod is pressed with the undergauge section, and tail end is a berrette file shape.
Be arranged at intervals with inferior circular, annular, polygon undergauge section on the excircle of body of rod afterbody successively, the total length that the undergauge section is provided with distribution is the 1/4-1/2 of body of rod length.
The tapering of the centre bore of described pallet is greater than 1 °.
The quantity of described spreading seam is greater than 1, and it highly be 1-5 a times of pallet height.
Diameter, the tapering of the tapering of described wedge, diameter and pallet are complementary, and its length is 1-5 times of pallet height.
Compared with prior art, the utility model has the advantages that:
1, processing technology is simply pollution-free.The utility model has been cancelled the screw thread of body of rod end, adopts wedge locking, at the end processing spreading seam of the body of rod, the other end is provided with the undergauge flattening and cuts point, processing technology is simple, saved fried dough twist formula anchor pole drawing, rolled thread, forging, twist operation such as flower, can reduce the processing cost 40% of anchor pole.The utility model processing need not heating, realizes smokeless production, and is free from environmental pollution.
2, support cost is low.Body of rod diameter of the present utility model is installed the comparable prior art of penetration rate and is doubled less than fried dough twist formula, pipe-seam type anchor rod, and the amount ratio prior art of anchoring agent reduces one times.Can reduce support cost greatly.
The explanation of accompanying drawing drawing
Fig. 1 is the utility model structural representation.
Fig. 2 be Figure 1A-A to sectional drawing, be the inferior circular undergauge segment structure schematic diagram that the utility model amplifies.
Fig. 3 be Figure 1B-B to sectional drawing, be the annular undergauge segment structure schematic diagram that the utility model amplifies.
Fig. 4 be Fig. 1 C-C to sectional drawing, be the polygon undergauge segment structure schematic diagram that the utility model amplifies.
The specific embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model is a kind of wedge-type anchor pole that tunnel and tunnel support are used that is used for.As Fig. 1, form by the body of rod 4 and the pallet 2, the wedge 1 that are used for connecting-rod body 4 usefulness.The body of rod 4 usefulness steel pipes are made, and its head is provided with spreading seam 3, and the effect of spreading seam 3 is fastening pallets 2.Pallet 2 is pegged graft by spreading seam 3 and fasteningly is connected with the body of rod 4, and the tapering of the centre bore of pallet 2 is greater than 1 °.For the body of rod 4 and pallet 2 are connected firmly, the utility model is provided with wedge 1 at the apical head of the body of rod 4, and pallet 2, wedge 1 insert to connect with the body of rod 4 by spreading seam 3 and be fixed together.Be arranged at intervals with 2-8 undergauge section 5 on the excircle of the afterbody of the body of rod 4 successively, form by inferior circle, annular, polygon undergauge section.As Fig. 2 is that the cross section is inferior circular undergauge section, is the undergauge section of ring-shaped section and ring-shaped as Fig. 3, is polygonal undergauge section as Fig. 4 cross section.Undergauge section 5 is an one with the body of rod, and its purpose that is provided with is the anchoring strength that increases the anchor hole on the body of rod 4 and the country rock, and the total length that undergauge section 5 is provided with distribution is the 1/4-1/2 of the body of rod 4 length.The afterbody top of the body of rod 4 is flattened triangular in shape, and this set drives the anchor pole rotation by electric drill or jumbolter during in order to the anchoring body of rod, will place the packing of the anchoring agent of bolthole to stir brokenly and mix.
The quantity of spreading seam 3 that is used for fastening pallet 2 is greater than 1, its height be pallet 2 height 1-5 doubly.For the body of rod 4 and pallet 2 are connected firmly, the tapering and the diameter of the tapering of wedge 1 and diameter and pallet 2 centre bores are complementary, and the length of wedge 1 is equal to or greater than the length of spreading seam 3.
Claims (5)
1, a kind of wedge-type anchor pole comprises the body of rod, and wedge is characterized in that: the body of rod head made from steel pipe has the spreading seam, and pallet, wedge are pegged graft with the body of rod by the spreading seam and be fixed together, and the afterbody of the body of rod is pressed with the undergauge section, and tail end is a berrette file shape.
