Description
Technical field
The utility model relates to the Bridge Construction field in construction project field, relates in particular to a kind of anticollision barrier for highway and Urban Bridge.
Background technology
According to existing bridge Construction Technology, as the anticollision barrier of ancillary facility, traditional construction method is all to adopt cast-in-place method construction.The construction of anticollision barrier is generally all arranged in that erection of precast beams completes and bridge floor leveling layer pouring concrete carries out after completing, or at cast-in-situ bridge girder, built, bridge floor construction of leveling blanket carries out after completing.Concrete the building of anticollision barrier adopts steel form segmentation pouring construction.Also just because of this feature of the arrangement of anticollision barrier working procedure and construction technology makes this traditional construction method have certain inadequate natural endowment, be embodied in the following aspects:
(1) because will wait until after main girder construction completes, could start construction, cause larger pressure to the duration control in Bridge Construction later stage, and unit in charge of construction often certainly will will increase the input of template, personnel and plant equipment for working to tight deadlines, construction cost also significantly rises.
(2) difficulty that presentation quality is controlled is large.Anticollision barrier adopts the construction technology of steel form section cast-in-place, determined that template will be through turnover use repeatedly, the distortion of template is increasing, add tight, concrete mixing quality of duration, the reasons such as mould of manually vibrating, rise, make difficulty that the Surface Quality of Concrete of anticollision barrier controls more and more greatly, the presentation quality of the anticollision barrier that waters out worse and worse, finally makes this problem become the common quality defect of bridge engineering.
(3) after damage, reparation difficulty is large, and security risk is higher.Once cast-in-situ steel reinforced concrete anticollision barrier is because of after accidental impact damages, also must adopt cast-in-place mode, repair comprises the links such as the cleaning of guardrail concrete, reinforcing bar recovery, branching standing template, concreting, form removal, maintenance, the time needing is long, larger to existing traffic impact, also there is the hidden danger of secure context simultaneously.
(4) cast-in-place anticollision barrier is because one-time-concreting sections is long, and the processing of deformation joint is more difficult, in construction, often because the concrete adhesion of deformation joint causes anticollision barrier to occur the Vertical Cracks running through, has influence on quality and safety.
Summary of the invention
In view of the deficiency that anticollision barrier conventional construction method exists, the utility model proposes a kind of ability simple, anti-dilatation of constructing strong and change assembled steel reinforced concrete anti-collision guard bar easy to maintenance.
The technical solution of the utility model is: by steel concrete anticollision barrier sections, be assembled successively, the both sides of described steel concrete anticollision barrier sections are all embedded with many horizontal location steel sleeve pipes, bottom surface from top to bottom and are embedded with many vertical steel plate internal thread sleeve pipes from left and right, and the location steel sleeve pipe of described adjacent steel concrete anticollision barrier sections is coordinated and pegged graft by pass force crossly bar; Described steel plate internal thread sleeve pipe is threaded connection fining twisted steel pull bar, and the other end of fining twisted steel pull bar is provided with leveling steel cushion block and anchoring nut.
Such scheme can further be improved to:
Described location steel sleeve pipe preferably adopts nominal bore 30mm～40mm coating steel pipe, and pass force crossly bar preferably adopts the round steel of diameter 28mm～32mm.
Described steel plate internal thread sleeve pipe is preferred inside and outside two rows that arrange, vertical bridge is arranged according to 50cm to spacing.
Described steel plate internal thread sleeve pipe comprises steel plate and the fining twisted steel pull rod coupling being welded to each other.
Described steel plate is preferably the steel plate of a block specifications 10cm * 10cm, thickness 16mm.
Described fining twisted steel pull bar preferably adopts the PSB830 fining twisted steel reinforcing bar of diameter 32mm.
The length of described steel concrete anticollision barrier sections is preferably 2.0m.
A kind of assembled steel reinforced concrete anti-collision guard bar of the present utility model is compared with existing cast-in-situ steel reinforced concrete anticollision barrier, has following remarkable advantage:
1, assembled steel reinforced concrete anti-collision guard bar can be in production department or special-purpose prefabricated place processing and fabricating, be convenient to control the precision that steel concrete anticollision barrier is made quality and built-in fitting, construction quality and make precision and can be guaranteed.
2, assembled steel reinforced concrete anti-collision guard bar, can shift to an earlier date processing and fabricating and complete, and after main girder construction completes, just can directly install, and construction technology is simple, and short construction period can shorten the construction period greatly.
3, the ability of the anti-dilatation of assembled steel reinforced concrete anti-collision guard bar is stronger.Because the existence of seam and dowel bar between sections, reduces rigidity between sections, compare with cast-in-situ steel reinforced concrete anticollision barrier, see that dilatation ability is stronger, not because dilatation causes guardrail to occur Vertical Cracks.
4, after the guardrail of indivedual sections damages, replacing is got up very easy, as long as the special-purpose anchoring nut (finish rolling deformed bar) below guardrail is come loose, just can change the sections of damage, facilitates the maintenance and management in later stage.
In view of the utlity model has above-mentioned advantage, compared with prior art, there is larger innovation, there is stronger application value, can be widely used in the construction of all kinds of highway bridges and the Urban Bridge anticollision barrier of straightway and curved section.
