Abstract
The utility model discloses an anchor head device for a tensile test piece of a glass fiber reinforced plastic anchor rod. The anchor head device comprises a steel tube, wherein a plug is arranged at one end of the steel tube; an adhesive is arranged in the steel tube; the other end of the steel tube is equipped with a steel cap. The steel tube is a two-section steel tube which is arranged at the two ends of the test piece respectively; each section of the steel tube is equipped with the plug, the adhesive and the steel cap. The test piece is arranged at the center of a central axis of the two-section steel tube. The plug is a PVC (polyvinyl chloride) plug. According to the anchor head device for the tensile test piece of the glass fiber reinforced plastic anchor rod disclosed by the utility model, the anchor head device is additionally arranged at the two ends of the test piece, so that requirements on a tensile strength test of the test piece of the glass fiber reinforced plastic anchor rod on a reinforcing steel bar testing machine can be satisfied.
Description
Technical field
A kind of glass fibre reinforced plastics rockbolts tensile test piece of the utility model anchor head assembly, for glass fibre reinforced plastics rockbolts test specimen test for tensile strength.
Background technology
Glass fibre reinforced plastics rockbolts is as a kind of new material, can cut, lightweight, intensity is high, good endurance and the advantage such as production cost is low owing to having, and adopts at coal and underground engineering construction field.Due to its distinctive fragility, on regular reinforcement testing machine, cannot directly carry out test for tensile strength.
Summary of the invention
The utility model provides a kind of glass fibre reinforced plastics rockbolts tensile test piece anchor head assembly.By installing this anchor head assembly additional at test specimen two ends, can meet glass fibre reinforced plastics rockbolts test specimen and on steel bar test machine, carry out the requirement of test for tensile strength.
The technical scheme that the utility model is taked is: a kind of glass fibre reinforced plastics rockbolts tensile test piece anchor head assembly, comprise steel pipe, and steel pipe one end is provided with stopper, is provided with bonding agent in steel pipe, and the steel pipe other end is provided with steel cap.
Described steel pipe is two sections of steel pipes, and two sections of steel pipes lay respectively at test specimen two ends, and each section of steel pipe is equipped with stopper, bonding agent and steel cap.Test specimen is positioned at the center of two sections of steel pipe central axis.Described stopper is PVC stopper.
A kind of glass fibre reinforced plastics rockbolts tensile test piece of the utility model anchor head assembly, PVC stopper both can leak stopping in the time of perfusion bonding agent, can ensure that again test specimen is positioned at steel pipe center.Steel cap can ensure in bonding agent solidification process, and test specimen is positioned at steel pipe center.This apparatus structure is simple, easy to operate; By this device, glass fibre reinforced plastics rockbolts can carry out test for tensile strength on steel bar test machine.
Brief description of the drawings
Fig. 1 is the utility model apparatus structure schematic diagram;
Fig. 2 is the utility model device partial cross sectional views.
Embodiment
As shown in Figure 1 and Figure 2, a kind of glass fibre reinforced plastics rockbolts tensile test piece anchor head assembly, comprises steel pipe 3, and steel pipe 3 one end are provided with stopper 5, are provided with bonding agent 4 in steel pipe 3, and steel pipe 3 other ends are provided with steel cap 2.Described steel pipe 3 is two sections of steel pipes, and two sections of steel pipes lay respectively at test specimen 1 two ends, and each section of steel pipe is equipped with stopper 5, bonding agent 4 and steel cap 2.Described stopper 5 is PVC stopper.Bonding agent 4 can be selected epoxies or resene bonding agent.
Implementation step:
First, test specimen 1 being put into two sections of steel pipes, put PVC stopper at test specimen 1 end, and PVC stopper is filled in respectively to wherein one section of steel pipe, to prevent that bonding agent 4 from spilling.Then keep test specimen 1 to be positioned at the center of this section of steel pipe central axis, the bonding agent 4 modulating is circulated into the space between test specimen 1 and steel pipe 3, and utilize the mode of knocking or vibrate to discharge the air in bonding agent 4.After perfusion, steel cap 2 is filled in respectively to the upper end of this section of steel pipe, to ensure that test specimen 1 in bonding agent 4 solidification processs is positioned at the center of this section of steel pipe central axis.Solidify after a period of time, process in the same way other one section of steel pipe for to be bonded dose 4.Test specimen 1 is positioned at the center of two sections of steel pipe central axis.By the utility model device, glass fibre reinforced plastics rockbolts can carry out test for tensile strength on steel bar test machine.
