Abstract
The invention relates to a composite anchorage for anchoring multiple fiber reinforcement plastic ribs or cables. One end of its porous anchor cup is connected with one end port of sleeve. There is porous constraint device at the other end of sleeve, which has fill insulation orifice and discharge port connected with the cone cavity. The smaller end of cone cavity is located at the end where the porous constraint device is set. Nuts are set round the sleeve. Multiple fiber reinforcement plastic ribs or cables pass through relative through holes on the porous constraint device respectively and ends are all set between two involutive clips and are compressed into cone holes of porous anchor cup. Said each rib or cable passes through the porous constraint device and thin-walled aluminum sleeve are mated on it at the location of clip. Sealing ring is set between the end of through hole with smaller diameter and corresponding rib or cable and reactive powder concrete is filled in the cone cavity of sleeve. It conquers the problem of earlier failure because of stress concentration. It can anchor multiple fiber reinforcement plastic ribs or cables. It is provided with compact structure, convenient usage, safety and reliability, and big anchoring force.
Description
Technical field
The present invention relates to structure technology, specifically be meant the composite anchorage of a kind of anchoring fibre reinforced plastic reinforcement or drag-line.
Background technology
Fibre reinforced plastics (FRP) are a kind of typical horizontal sight isotropic materials, it is horizontal and longitudinal strength is smaller, traditional strand tapered anchorage will no longer be applicable to the FRP muscle, otherwise will cause the ground tackle assembly to cause generation initial failure in the anchorage zone because stress is concentrated owing to its transverse strength is low excessively.
Summary of the invention
The objective of the invention is, defective at the prior art existence, a kind of composite anchorage that is used for anchoring plurality of fibers reinforced plastic muscle or drag-line is proposed, its optimized integration design feature of strand tapered anchorage and bond type anchorage, it can overcome existing ground tackle causes problem that initial failure takes place and effectively anchoring plurality of fibers reinforced plastic muscle or drag-line in the anchorage zone because stress is concentrated, and compact conformation, easy to use, safe and reliable.
Technical scheme of the present invention is, the described composite anchorage that is used for anchoring plurality of fibers reinforced plastic muscle or drag-line, comprise the porous anchor cup that has a plurality of band tapering through holes, its design feature is, one end of this porous anchor cup is connected with sleeve one end port and the more small-bore end of described band tapering through hole is positioned at this link of anchor cup, cylindrical shell two that its other end is equipped with the described sleeve of porous restraint device is respectively equipped with fill orifice and the steam vent that is communicated with conical cavity in the cylindrical shell, the less end of described conical cavity is positioned at the end that sleeve is equipped with described porous restraint device, described sleeve periphery is provided with external screw thread and nut is housed, plurality of fibers reinforced plastic muscle or drag-line pass through hole corresponding on the porous restraint device respectively, and an end of every fiber reinforced plastic rod or drag-line all places between two involutory band tapering arc clips and is pressed into porous anchor cup is with the tapering through hole accordingly, the through hole that described every fiber reinforced plastic rod or drag-line pass described hole restraint device is with the Thin-walled Aluminum sleeve pipe respectively with the position that is positioned at described intermediate plate, be provided with sealing ring between the more small-bore end of band tapering through hole of porous anchor cup and respective fiber reinforced plastic muscle or the drag-line, be full of the RPC of injecting by described fill orifice in the conical cavity of sleeve.
Below the present invention made further specify.
When reality is used; being with fibre reinforced plastics (FRP) muscle of Thin-walled Aluminum sleeve pipe 3 or drag-line 9 is clipped in the folder muscle hole (i.e. the arc through slot 17 involutory structures that become of two intermediate plates) between the intermediate plate 4; and the intermediate plate that will accompany fiber reinforced plastic rod or drag-line is pressed in the band tapering through hole 14 of porous anchor cup 5; carry out pre-stretch-draw; again sleeve 11 and porous anchor cup 5 are linked together; put described sealing ring 6 again; porous restraint device 13 is installed; pour into cementing medium RPC 8 (RPC) to the conical cavity 16 of sleeve 11 from fill orifice 7; till steam vent 12 overflows; and installation locking device 2; cover top nut 10; anchor on the structure, load onto protective cover 1 at last.
The present invention is cascaded and is formed by intermediate plate anchor and bonding anchor by selecting excellent.The intermediate plate anchor is made up of described porous anchor cup 5, band tapering arc clip 4 and Thin-walled Aluminum sleeve pipe 3 etc., the bonding anchor is made up of sleeve 11, RPC (RPC) 8, porous restraint device 13 etc., and it is by common anchoring fibre reinforced plastic reinforcement of the chucking power of the bond stress of cementing medium and intermediate plate or drag-line.Its anchoring principle is, when using jack tension fiber reinforced plastic rod or drag-line, the fiber reinforced plastic rod of loading end or drag-line produce the trend of axial slip, cause and produce fiber reinforced plastic rod or the adhesion stress of drag-line and cementing medium and the frictional force of fiber reinforced plastic rod or drag-line and intermediate plate, resist the stretching force of fiber reinforced plastic rod or drag-line jointly, reach the purpose of anchoring fibre reinforced plastic reinforcement or drag-line; It makes intermediate plate anchor and bonding anchor common anchoring FRP muscle or drag-line along with the increase of stretching force.
As known from the above, the present invention is a kind of composite anchorage that is used for anchoring plurality of fibers reinforced plastic muscle or drag-line, its optimized integration design feature of strand tapered anchorage and bond type anchorage, overcome existing ground tackle in the anchorage zone because stress is concentrated the problem that initial failure takes place that causes, effectively anchoring plurality of fibers reinforced plastic muscle or drag-line, and compact conformation, easy to use, safe and reliable, anchored force is big.
