Description
Technical field
The present invention relates to a kind of anchor device that is subjected to lacing wire (rope) material, relate in particular to a kind of FRP muscle bond type anchorage and implementation method thereof.
Background technology
The horizontal shear strength of material of FRP muscle (fibre reinforced composites) is lower, and existing FRP muscle ground tackle mainly contains bonded, clipping and combined type (straight tube+inner cone).The bonding colloid has protective effect to the FRP muscle in the bond type anchorage.The stress distribution on muscle material surface presents " broad in the middle small in ends " in the anchor tube, the rule of " the big flat segments of awl section is little ", and relevant with the inner roughening degree of anchor tube.Clipping ground tackle easily produces circumference stress and concentrates, and causes the muscle material to crush destruction, and anchoring efficient is low.The complex structure of composite anchorage to ground tackle material requirements height, has increased cost, be unsuitable for large-scale production and application, and anchorage length is big, and anchoring efficient is lower, is unfavorable for the raising of anchor tube tonnage.
Summary of the invention
The problem to be solved in the present invention provides a kind of anchoring efficient height,, low cost of manufacture low to muscle material damage and is beneficial to FRP muscle that anchor tube tonnage improves with bond type anchorage and implementation method thereof.
In order to address the above problem, the invention provides a kind of FRP muscle bond type anchorage, comprise that anchor tube, nut and end are stifled, it is stifled that described anchor tube two ends are provided with end, described anchor tube is provided with glue filling opening, the stifled locating hole that is provided with of described end, described anchor tube comprises slippage anchor tube and mooring anchor tube, described slippage anchor tube and mooring anchor tube outer surface are provided with screw thread, described slippage anchor tube is connected by fixed by nut with the mooring anchor tube, described screw thread and nut are suitable, and described slippage anchor tube inner surface is shiny surface, and described mooring anchor tube inner surface is matsurface.
As a further improvement on the present invention, described slippage anchor tube or mooring anchor tube interior shape are: an end is flat segments, and the other end is the awl section of varied angle, and described flat segments is continuous shape with the awl section.
As a further improvement on the present invention, described slippage anchor tube, mooring anchor tube respectively are provided with at least one.
As a further improvement on the present invention, described nut is provided with adjusting device, and described adjusting device comprises pin hole and latch, and described pin hole and latch are provided with screw thread, described pin hole and latch by being threaded.
As a further improvement on the present invention, described end is stifled to be provided with boss, and the two ends of described boss and slippage anchor tube or mooring anchor tube are suitable, and described boss thickness is 3mm, and described end is stifled to be centered close on the axis of slippage anchor tube or mooring anchor tube.
As a further improvement on the present invention, the described FRP muscle implementation method of bond type anchorage is characterized in that: may further comprise the steps:
Step 1: by mooring anchor tube and the nut of being threaded, stifled, the nut of FRP muscle material is stifled from holding, slippage anchor tube, end, mooring anchor tube, end pass stifled successively again;
Step 2: fixedly the end at slippage anchor tube two ends is stifled;
Step 3: by slippage anchor tube and the nut of being threaded, make slippage anchor tube be connected by fixed by nut with the mooring anchor tube, FRP muscle material location;
Step 4: fixedly the end of mooring anchor tube is stifled;
Step 5: carry out encapsulating with pressure encapsulating equipment from the glue filling opening opening part, all locating holes stifled up to end all have colloid to overflow, and finish encapsulating;
Step 6: repeat above-mentioned steps, i.e. FRP muscle bond type anchorage installation at the FRP muscle material other end.
Compare with prior art or structure, beneficial effect of the present invention is.
(1) described anchor tube comprises slippage anchor tube and mooring anchor tube, and described slippage anchor tube and mooring anchor tube outer surface are provided with screw thread, and described slippage anchor tube inner surface is shiny surface, and described mooring anchor tube inner surface is matsurface.When stretch-draw, big relative slippage can take place with the FRP muscle in slippage anchor tube, forms big active force on FRP muscle surface; But this displacement does not just meet the requirement of actual engineering too greatly, and the matsurface of mooring anchor tube inner surface has retrained this slippage.The present invention is applicable to the ground tackle of large-tonnage FRP muscle.
(2) described slippage anchor tube is connected by fixed by nut with the mooring anchor tube, and described screw thread and nut are suitable, and described slippage anchor tube or mooring anchor tube interior shape are: an end is flat segments, and the other end is the awl section of varied angle, and described flat segments is continuous shape with the awl section.The present invention takes full advantage of single anchor tube to the cementitiousness of FRP muscle, and (the anchoring efficient of this moment is higher) connects two anchor tubes by nut, thereby obtain higher overall anchoring efficient under the less situation of single anchor tube length degree.
(3) anchor barrel structure of the present invention is simple, and low cost of manufacture is low to material requirements, is suitable for large-scale industrialization production.And the binding material that implementation process is used can effectively be protected the FRP muscle, reduces the damage of FRP muscle, guarantees to implement safety.
