Abstract
The utility model discloses an indentation metal sleeve type frp flexible anchor rod, which is composed of a frp rod and an anchor tail of the metal sleeve. The connection of the anchor tail of the metal sleeve adopts the method that the metal sleeve and the rod that is nested with the metal sleeve are fixedly connected together as a whole. That is, in the process of molding the frp rod, one indentation groove or a plurality of indentation grooves with a certain taper is or are extruded out on a certain part (or plural parts) of a section of length where the metal sleeve and the frp rod are nested so that the metal sleeve and the frp rod can be fixedly connected together as a whole. The utility model has the advantages of high intensity, large anchoring force and flexibility with cutting function. Therefore, the utility model is applicable in the anchorage of the mine project, the tunnel project, the military industry project and the civil project, particularly in the anchor rod supporting of the coal mine.
Description
Technical field
The utility model relates to a kind of impression metallic sheath tubular type glass fiber reinforced plastic flexible roof bolt.Relate in particular to a kind of supporting product that the colliery underworkings uses that is used for.
Background technology
Along with the development of mine bolt support technology, anchor pole increases gradually at the consumption of down-hole.In some cases, as help at coal road two with work plane open-off cut coal group in, but require the body of rod of the anchor pole that uses to have cutting.The used anchor pole that cuts mainly is wood bolt and bamboo anchoring-bolt, and they exist, and anchored force is low and unstable, processing and fabricating is difficult, shortcomings such as easy corrosion and damage.In order to address this problem, in recent years, all developed glass fibre reinforced plastics rockbolts both at home and abroad, open otch at body of rod rear and fill in chock or boring and the mode of pin fixing metal sleeve pipe is installed forms the anchor tail but existing glass fibre reinforced plastics rockbolts generally adopts, destroyed the overall structure of the body of rod, reduced lever strength, anchored force is less.Therefore, the glass fibre reinforced plastics rockbolts that uses at present awaits improving.
In addition, adopt high-intensity glass fibre reinforced plastics rockbolts, can reduce support cost significantly in the place of adopting anchor metal.And the glass fibre reinforced plastics rockbolts body of rod has flexibility, can overcome the defective that present anchor rod body flexibility is little, rock-bolt length is subjected to the drift section restriction, can further enlarge the scope of application of anchor pole.
Summary of the invention
The utility model purpose is to overcome the defective that existing glass fibre reinforced plastics rockbolts anchor tail connects, and improves the reliability that glass fibre reinforced plastics rockbolts anchor tail connects, thereby improves the anchored force of glass fibre reinforced plastics rockbolts.This glass fiber reinforced plastic flexible roof bolt is made up of the glass fiber reinforced plastic body of rod and metal sleeve anchor tail, and metal sleeve is provided with external screw thread outward.It is characterized in that: the body of rod section integral body of metal sleeve and its socket is fixed together, promptly in the process of formed glass steel pole body, on certain (or the some) position on the segment length that metal sleeve and the glass fiber reinforced plastic body of rod socket-connect, squeeze out the indentation cavity that one or several has certain taper, the metal sleeve and the glass fiber reinforced plastic body of rod are fixed together.The indentation cavity of described metal sleeve has certain tapering.
The utility model compared with prior art has the following advantages:
1. compare with existing glass fibre reinforced plastics rockbolts, the anchor tail connect to adopt whole affixed, does not destroy the overall structure of the body of rod, therefore, have connect reliable, intensity height, advantage such as anchored force is big, and manufacture craft is simple.
2. compare with bamboo anchoring-bolt with wood bolt, the utlity model has corrosion-resistant, the intensity height; Compare with anchor metal, but the utlity model has cutting, pliability, and cost is than low many of anchor metal.
Description of drawings Fig. 1 is the utility model schematic diagram; Fig. 2 is the A-A sectional view of Fig. 1; Fig. 3 is the utility model working state schematic representation.
The specific embodiment
Impression metallic sheath tubular type glass fiber reinforced plastic flexible roof bolt (Fig. 1, Fig. 2) is made up of the glass fiber reinforced plastic body of rod 3 and metal sleeve anchor tail 1, metal sleeve round steel pipe manufacturing, and its internal diameter and the glass fiber reinforced plastic body of rod are complementary.In the utility model process for making, metal sleeve is enclosed within the socket part of the glass fiber reinforced plastic body of rod, in the mould of particular design, push, metal sleeve is deformed, produce equally distributed four indentation cavity 4 that have certain taper, metal sleeve and glass fiber reinforced plastic body of rod integral body are fixed together, and then on metal sleeve external threading 2, thereby realize the purpose of this utility model.When the utility model uses (please refer to Fig. 3) under coal mine, on the rib of tunnel, get out anchor hole in advance, the anchoring agent 5 of packing at the bottom of the hole, reinstall the glass fibre reinforced plastics rockbolts body of rod and stir the anchoring agent, make it in conjunction with evenly closely knit, after the anchoring agent is solidified, dress plate washer 6 on the anchor tail, refill nut 7, thereby realize supporting rib.
Claims (2)
1. impression metallic sheath tubular type glass fiber reinforced plastic flexible roof bolt, comprise the glass fiber reinforced plastic body of rod and metal sleeve anchor tail, metal sleeve is got on the bus and is shaped on external screw thread, it is characterized in that: on the segment length that metal sleeve and the glass fiber reinforced plastic body of rod socket-connect, squeeze out one or several indentation cavity, metal sleeve and glass fiber reinforced plastic body of rod integral body are fixed together.
2. impression metallic sheath tubular type glass fiber reinforced plastic flexible roof bolt as claimed in claim 1, it is characterized in that: the indentation cavity on the described metal sleeve has certain tapering.
