Description

A kind of Detachable multilayer carbon cloth anchor

Technical field

This utility model belongs to prestressed reinforcement concrete correlative technology field, it is proposed that a kind of Detachable multilayer carbon cloth anchor, it is adaptable to the anchoring function in the Concrete base facility engineering structure such as building, water conservancy.

Background technology

For a long time, the objective factors such as candle, material aging are invaded because of environment, the anthropic factors such as design error or construction wrong, structure institute function changes, is changed by purposes such as load increases, the act of god effects such as war, fire, snowstorm, earthquake, flood desert, and the amendment of relevant design codes specification, to many reasons such as the raisings of structural safety reserve requirements, a large amount of works with and the engineering structure such as civil buildings, traffic bridge need to carry out repairing and reinforcement.High-strength carbon fiber composite, have lightweight, high intensity, low creep, the performance such as low thermal coefficient of expansion and good acid-alkali-corrosive-resisting, the development for civil engineering provides more wide space.But, current substantial amounts of achievement in research and engineering example show, the method using fibre reinforced to reinforce comes with some shortcomings, such as, elastic modelling quantity is too low relative to its intensity, and intensity utilization ratio is too low, cause suppress malformation, crack extesion effect little；In addition, anchorage part design is unreasonable, construction inconvenience, is susceptible to shear and stripping damage, makes the intensity of carbon cloth to make full use of, reduces anchor system service life, is difficult to ensure that architectural effect.

Utility model content

Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of Detachable multilayer carbon cloth anchor is provided, the convenience operated during to improve civil structure anchoring and the reliability of anchoring so that it is be satisfied with the demand of through engineering approaches application.

For achieving the above object, the utility model discloses following technical scheme:

A kind of Detachable multilayer carbon cloth anchor, including anchor block and jacking block two parts:

Described anchor block includes fixture and lower clamp two parts, the front end of upper lower clamp is respectively provided with outer convex globoidal, upper and lower fixture forms location by the concaveconvex structure mutually agreed with, the core of upper and lower fixture is provided with the first through hole carrying out carbon cloth winding, marginal portion is provided with the bolt hole of symmetry simultaneously, and upper fixture is fixed together with lower clamp by bolt by bolt hole；

Described jacking block includes being bolted to connection upper jacking block together and lower jacking block, jacking block has corresponding with anchor block to intrados, can split mutual with anchor block, jacking block is additionally provided with the installing hole for being connected with concrete, and draws the second through hole of carbon cloth.

As a kind of preferred version, the lower surface edge of described upper fixture has downward projection, and the top surface edge of lower clamp is provided with the groove of correspondence.

As a kind of preferred version, the bolt hole on described anchor block is symmetrical arranged.

Disclosed in this utility model, a kind of Detachable multilayer carbon cloth anchor, has the advantages that

1, reusable, anchoring efficiency is high, it is possible to realizing the multi-storey up-down and translation anchoring to xoncrete structure, shaped form feature ensure that the uniformity of pulling force simultaneously simultaneously, it is to avoid causes carbon fiber board stress distribution uneven.

2, anchorage is detachable, simple in construction, and operation step plays simplicity, and the anchor structure of formula is easier to implement.

3, anchoring effect is reliable, gives full play to the ultimate strength of carbon fiber board, improves the rate of utilization of strength of carbon fiber tape.

Detailed description of the invention

Below in conjunction with embodiment and referring to the drawings this utility model is further described.

Refer to Fig. 1-Fig. 3.

A kind of Detachable multilayer carbon cloth anchor, including anchor block 1 and jacking block 2 two parts:

See Fig. 2 (a), anchor block 1 includes fixture 11 and lower clamp 12 two parts, the front end of upper lower clamp is respectively provided with outer convex globoidal, upper and lower fixture forms location by the concaveconvex structure mutually agreed with, the core of upper and lower fixture is provided with and carries out the first through hole 13 that carbon cloth 3 is wound around, marginal portion is provided with the bolt hole 14 of symmetry simultaneously, and upper fixture 11 is fixed together with lower clamp 12 by bolt 15 by bolt hole 14；

See Fig. 2 (b), jacking block 2 includes being bolted to connection upper jacking block together and lower jacking block, jacking block 2 has corresponding with anchor block 1 to intrados, can split mutual with anchor block 1, it is additionally provided with the installing hole 21 for being connected with concrete on jacking block 2, and draws the second through hole 22 of carbon cloth.

In the present embodiment, the lower surface edge of upper fixture 11 has downward projection, and the top surface edge of lower clamp 12 is provided with the groove of correspondence.

This utility model is when anchoring, according to the predetermined direction reinforced and distance, firstly the need of installing jacking block 2 to xoncrete structure, then two bundle carbon cloths 3 are wound around fixture 11 and lower clamp 12 respectively, and when being wound around, carbon cloth 3 is penetrated by the first through hole 13, passed by the rear surface of fixture again, after winding, the carbon cloth end not being wound around is extraction in the middle of upper and lower fixture, is then passed through the second through hole 22 of jacking block 2.When drawing carbon cloth 3, anchor block 1 coordinates with the shaped form feature of jacking block 2, makes anchor block 1 be formed fixing, and achieves the orientation of carbon cloth 3.

It should be noted that the carbon cloth 3 in this utility model needs through pre-preg, carbon cloth 3 needs first it fully to be infiltrated in prepreg, after dipping, re-use anchor to be wound, after treating that it has solidified, then carry out assembling and be installed to reinforce position.

The above is only preferred implementation of the present utility model, is not intended to limit；Should be understood that, although this utility model being described in detail with reference to the various embodiments described above, it will be understood by those within the art that, the technical scheme described in the various embodiments described above still can be modified by it, or the most some or all of technical characteristic is carried out equivalent；And these amendments and replacement, do not make the essence of corresponding technical scheme depart from the scope of this utility model each embodiment technical scheme.
