Description

A kind of ring anchor integral sealing anti-corrosive apparatus

Technical field

The present invention relates to a kind of prestress wire anchor head anti-corrosive apparatus, particularly a kind of ring anchor integral sealing anti-corrosion dress Put.

Background technology

In prestressed reinforced concrete structure engineering, because the prestressing force that non-bending steel cable applies all is passed by anchorage It is delivered in structure, so the requirement for anticorrosion to anchorage and presstressed reinforcing steel is very high.

The applicant once applied for that a Authorization Notice No. was entitled for CN201033913Y《Unbonded tendon ring anchor anchor Head anti-corrosive apparatus》, preferably solve the problems, such as integrally to carry out unbonded tendon anchor head long-time, effective anti-corrosion, it is particularly suitable In the overall anti-corrosion to unbonded tendon annular anchorage anchor head.

But the patent is found in practice, and there is also in place of some shortcomings：

1）The unbonded tendon ring anchor anchor head anti-corrosive apparatus is divided into the mode of the closing of lower half box or the docking of the box of left and right half, box-like Protective cover when mounted, influenceed by notch is undersized, it is not easy to install；

2）The device space-consuming is larger, influences the stretching construction of ring anchor；Anti-corrosive apparatus length is longer, it is necessary to the ring of perfusion Oxygen preservative substance is more, and structure is bigger than normal, and epoxy anticorrosion material intensity is low, influences the bulk strength of notch；

3）The unbonded tendon ring anchor anchor head anti-corrosive apparatus anchor slab is not relatively fixed with anchor slab position, operation inconvenience.

The content of the invention

It is an object of the invention to provide a kind of ring anchor integral sealing anti-corrosive apparatus, the device is than existing soap-free emulsion polymeization anchor head Anti-corrosive apparatus is simple in construction, easy for construction, occupies little space, and notch bulk strength is high, and can be reliably to anchor head and without viscous Tie muscle and carry out permanently effective anti-corrosion.

The technical scheme to solve the above problems is：A kind of ring anchor integral sealing anti-corrosive apparatus, the ring anchor integral sealing anti-corrosion Device includes right baffle-plate, right shell body, bandage and connection nylon jacket, and right baffle-plate, right shell body are distributed in anchorage both ends, connected by bandage Connect the hollow cavity of nylon jacket composition closing；The right baffle-plate, right shell body end face are provided with answering anchoring prestress muscle number on anchor slab Corresponding n are used to the hole for wearing unbonded tendon, the grouting for irrigating preservative substance is reserved with baffle plate end face or nylon jacket Hole, m sliver transvers sections are provided with side as U types or the little groove of V types；It is external in right baffle-plate, right shell body or nylon jacket Grouting Pipe, integral sealing anti-corrosion of the epoxy resin mortar realization to unbonded tendon ring anchor anchor head is filled up in inner chamber；Above-mentioned m, n value Scope is：M be 1,2 or 3 between arbitrary integer, any even numbers of the n between 2-8.

It is beneficial below due to being had using a kind of ring anchor integral sealing anti-corrosive apparatus of above-mentioned technical proposal, the utility model Effect：

1st, it is easy for construction, occupy little space：

A kind of ring anchor integral sealing anti-corrosive apparatus of the utility model includes right baffle-plate, right shell body, bandage and connection nylon Set, right baffle-plate, right shell body are distributed in anchorage both ends, and connecting nylon jacket by bandage forms totally enclosed hollow cavity, in left gear The external Grouting Pipe of plate, right shell body, epoxy resin mortar is filled up in inner chamber, ring anchor anchor head is in totally enclosed space, is realized to without viscous Tie the integral sealing anti-corrosion of muscle ring anchor anchor head.

Because nylon or braid terminate to be fixed in left baffle again after cutting steel strand wires in ring anchor tensioning, institute Reinforcing bar length is adjusted after spacing between baffle plate can terminate the cutting of rear anchor head according to tensioning, not only reduced device space-consuming but also Good antiseptic effect can be reached, construction is flexible.

2nd, simple in construction, easy to process, cost is low：

A kind of ring anchor integral sealing anti-corrosive apparatus main body of the utility model is right baffle-plate, right shell body adds nylon braid, Simple in construction, easy to process, cost is low.

Due to above feature, a kind of ring anchor integral sealing anti-corrosive apparatus of the utility model is applied to unbonded tendon anchor head It is overall to carry out long-time, effective anti-corrosion, especially suitable for the overall anti-corrosion to unbonded tendon annular anchorage anchor head.

Below, in conjunction with the accompanying drawings and embodiments to a kind of technical characteristic of ring anchor integral sealing anti-corrosive apparatus of the utility model It is further described.
