Abstract
The utility model relates to a novel stock with activity barb, including activity barb, the stock body, movable tube, nut, the activity barb distributes on the stock body quartering point all around, and the movable tube parcel is connected with the stock body and gasket in the stock body periphery, and the nut is located the one end that the stock body has the gasket. The utility model relates to a novel stock that has activity barb, simple structure, the installation and after applying the pretightning force through the nut, the stock body activity barb all around inserts around the ground internal and ground body form a whole, has increased anchor power, makes the stock more difficult landing. The movable pipe connected with the anchor rod body and the gasket is adopted to control the movement of the movable barbs, and the recovery is facilitated.
Description
Technical Field
The utility model relates to an anchor rod especially relates to a novel anchor rod with activity barb.
Background
The anchor rod has wide application in the field of rock and soil support. The whole anchor rod is divided into a free section and an anchoring section, wherein the free section is an area for transmitting the pulling force at the head of the anchor rod to an anchoring body and has the function of applying prestress to the anchor rod; the anchoring section is an area where the prestressed tendons and the soil layer are bonded by cement paste, the anchoring section has the functions of increasing the bonding friction effect of the anchoring body and the soil layer, increasing the bearing effect of the anchoring body, and overcoming the defect that the tensile capacity of the rock-soil body is far lower than the compressive capacity through the longitudinal tension effect of the anchor rod body.
The existing anchor rod has simple structure and limited anchoring part, and particularly, the common anchor rod only provides anchoring force by the rod body, so that the anchor rod is insufficient in anchoring force and easy to slip in many projects.
SUMMERY OF THE UTILITY MODEL
The utility model provides a novel anchor rod with movable barbs, wherein the movable barbs are distributed on four equal points around the anchor rod body and are connected with the anchor rod body through a rotating shaft, so that the anchor rod body can be freely attached or kept away, and the movable barbs extend out of the movable pipe through rectangular holes on the movable pipe; the movable pipe is wrapped on the periphery of the anchor rod body and can be bent, and a rectangular hole is formed near the movable barb to limit the movable range of the movable barb; the movable barb is attached to the anchor rod body when the anchor rod is placed into the drilled hole; apply the pretightning force with the nut and pull out the stock body outside drilling to the stock, the relative stock body of movable tube stretches into to drilling, and the movable tube passes through the restriction of rectangle aperture to the activity barb to make the activity barb open, increased the stability and the tensile strength of stock.
The utility model has the advantages that: simple structure, the stock is located the internal new complex body that forms with the ground body of ground to make the bearing capacity of ground body self strengthen greatly, increased anchor power, make the difficult landing of stock.

Detailed Description
The present invention will be described with reference to the schematic structural diagram of the anchor rod in the accompanying drawings.
The anchor rod comprises a movable barb 1, an anchor rod body 2, a movable pipe 3 and a nut 4.
The anchor rod body 2 is cylindrical, the diameter of the anchor rod body 2 is 45-55mm, and the length of the anchor rod body is 1.8-2.0 m. The free end of the anchor rod body 2 is provided with a thread with a certain length, the length of the thread is 200-300 mm, and the thread is also provided with a tray 5 and a nut 4 from inside to outside. The anchor rod body is welded with a movable barb 1 with a rotating shaft, the length is 80-100mm, and the diameter is 3-5 mm. The periphery of the anchor rod body 1 is provided with a circle of flexible pipe 3 which can be bent and moved and is connected with the gasket and the tail end of the anchor rod body, and the length of the flexible pipe is 1.6-2.0 m. The diameter is 60-80 mm.
The use method of the anchor rod comprises the following steps: drilling a drill hole in the rock body, wherein the diameter of the drill hole is 3-5mm larger than the diameter of the whole anchor rod; in the middle of inserting the drilling with the stock that has activity barb 1, press close to the gasket on the rock mass through the nut 4 of screwing, apply the pretightning force to the stock, make the stock body 2 pull out outward to the drilling, the activity pipe 3 stretches into to the drilling is interior, and activity barb 1 opens and inserts in the rock mass on every side.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
