Abstract
The utility model discloses a cast-in-place outer vertical face seamless seal anchor structure which comprises a box beam provided with an anchor port and a seal anchor template which is attached to the box beam through a plurality of tie pieces and covers the anchor port. A sleeve communicated with the anchor port is embedded at the top of the box beam, and a vibration rod is inserted into the sleeve. By means of a concentrator, the cast-in-place outer vertical face seamless seal anchor structure with strong uniformity between seal anchor concrete and an outer vertical face of whole box beam concrete is achieved. The cast-in-place outer vertical face seamless seal anchor structure has the advantages of avoiding manual filling decoration and being seamless and attractive.
Description
Technical field
The utility model relates to a kind of sealing off and covering anchorage structure, the outer seamless sealing off and covering anchorage structure of facade of espespecially a kind of Cast-in-situ Beam.
Background technology
In bridge on highway, Urban Bridge and railroad bridge now; More use the prestressed concrete cast-in-situ box girder.Using in large quantities prestressing force is a trend of bridge development, but problem is that Cast-in-situ Beam is after using prestressing force, and particularly after using transverse prestress, its anchor mouth position is located at the outer facade of case beam often.Traditional sealing off and covering anchorage technique is to establish the concrete casting orifice in the upper end of sealing off and covering anchorage template, then can cause the template of sealing off and covering anchorage mouth can't once stand the top, from long-term Construction practices, this kind sealing off and covering anchorage method is vibrated because concrete can't adopt vibrating head, can only adopt artificial simple tamping, be difficult to guarantee the concrete quality of sealing off and covering anchorage; And since the template of sealing off and covering anchorage once Zhi Li put in place, need to reserve concrete pouring gate, its manually shutoff of sprue gate topmost, the concrete of sealing off and covering anchorage is difficult to accomplish smooth closely knit like this, the outer facade of whole case beam is difficult to keep apparent uniformity, have larger repairing vestige, there are larger defective in this and the bridge fair-faced concrete outward appearance that requires now.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and provide the seamless sealing off and covering anchorage structure of facade outside a kind of Cast-in-situ Beam, realized the outer seamless sealing off and covering anchorage structure of facade of Cast-in-situ Beam that the outer facade uniformity of a kind of sealing off and covering anchorage concrete and whole box beam concrete is strong, have and need not manually to fill up modification, seamless advantage attractive in appearance.
The technical scheme that realizes above-mentioned purpose is:
The outer seamless sealing off and covering anchorage structure of facade of a kind of Cast-in-situ Beam of the present utility model, comprise the case beam that offers the anchor mouth and by fit described case beam and cover the sealing off and covering anchorage template of described anchor mouth of a plurality of lacing wires, the sleeve pipe that a plurality of and described anchor mouth is communicated with is buried at the top of described case beam underground; Be inserted with respectively a vibrating head in the described sleeve pipe.
Described case beam upper surface is given prominence in the upper end of above-mentioned sleeve pipe, and the lower end of described sleeve pipe is charged in the described anchor mouth.
Above-mentioned sleeve pipe is bellows.
The utility model has been owing to adopted above technical scheme, makes it have following beneficial effect to be:
Because the employing of the sleeve pipe that is communicated with the anchor mouth of case beam, thereby realize anchor mouth concreting from case back section, need not on the sealing off and covering anchorage template, to offer in addition plug hole, realized case beam outward flat appearance and the uniformity of facade, need not to carry out follow-up repair procedure; The simultaneously employing owing to sleeve pipe can realize inserting the automatic stirring that vibrating head is realized mixed earth, thereby has reduced constructor's labour intensity, has guaranteed the mixing quality of mixed earth, has improved the efficiency of construction of engineering.
Description of drawings
Fig. 1 is the structural representation of the outer seamless sealing off and covering anchorage structure of facade of the utility model Cast-in-situ Beam.
The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
See also Fig. 1, the outer seamless sealing off and covering anchorage structure of facade of a kind of Cast-in-situ Beam of the present utility model, comprise the case beam 1 that offers anchor mouth 11 and by a plurality of lacing wire 2 applying case beams 1 and cover the sealing off and covering anchorage template 3 of anchor mouth 11, the top of case beam 1 is embedded with a plurality of sleeve pipes 4 that are communicated with anchor mouth 11; The sleeve pipe 4 interior vibrating heads 5 that are inserted with respectively.Case beam 1 upper surface is given prominence in the upper end of sleeve pipe 4, and the lower end of sleeve pipe 4 is charged in the anchor mouth 11.Sleeve pipe 4 is bellows.
Because the employing of the sleeve pipe 4 that case beam 1 is communicated with anchor mouth 11, thereby anchor mouth 11 concretings from case beam 1 top have been realized, need not on sealing off and covering anchorage template 3, to offer in addition plug hole, realized flat appearance and the uniformity of case beam 1 outer facade, need not to carry out follow-up repair procedure; The simultaneously employing owing to sleeve pipe 4 can realize inserting the automatic stirring that vibrating head 5 is realized mixed earth, thereby has reduced constructor's labour intensity, has guaranteed the mixing quality of mixed earth, has improved the efficiency of construction of engineering.
The utility model is based on satisfying under the prerequisite of impression quality of the concrete closely knit and guard box beam 1 outer facade of sealing off and covering anchorage as far as possible, the sealing off and covering anchorage template 3 at anchor mouth 11 positions once Zhi Li puts in place, form the cavity of sealing, need not reserve the filling concrete mouth, while pre-buried bellows in anchor mouth 11 upper tank beams 1 concrete roof, bellows is suitable for reading to be passed from case beam 1 end face; End opening inserts anchor mouth 11, forms the concrete passage of perfusion sealing off and covering anchorage; And utilizing this passage, vibrating head 5 stretches into anchor mouth 11 in bellows, carry out the concrete operation of vibrating.Can guarantee that like this sealing off and covering anchorage concrete once-cast puts in place, manually not fill up modification at needs, guarantee the uniformity of the outer facade of sealing off and covering anchorage concrete and whole case beam 1 concrete, guarantee as much as possible the impression quality of clear-water concrete.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not consist of restriction of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
