Abstract
The utility model discloses a novel wall fence used for a road, which comprises an inside prefabricated layer and an outside cast-in-place layer that are solidified together, wherein the outside cast-in-place layer is formed by the cast-in-place of a framework of steel reinforcement and concrete; the inside prefabricated layer is formed by arranging prefabricated blocks side by side; and carbomer is filled in the gas between the adjacent prefabricated blocks. The novel wall fence is made by the method of combining a prefabricated fence panel and the cast-in-place and has high strength, attractive shaping and high fineness; in addition, a vibrating table is prefabricated, thereby avoiding the honeycomb and the pitted surface, reducing the porosity of the cast-in-place concrete and improving the grade strength and the compactedness of fence, so as to effectively prolong the service life of the fence and lower the maintenance cost at the later stage.
Description
One. technical field: the utility model relates to a kind of highway barrier, particularly relates to a kind of novel wall fence for highway.
Two. background technology: along with the development of economic technology, China Higher level highway is more and more, various forms of bridges are also more and more, in order to adapt to expressway safety, requirement economic, practical, attractive in appearance, on highway and bridge, all design guardrail during design, the guardrail that has is the railing type waveform configuration, is made of column and horizontal Crashworthy plate, generally is used in the roadbed range section; Another guardrail is a wall type structure, and cast-in-site forms, and generally is used in bridge construction beyond the region of objective existence side.But, corrugated guardrail only is used in the roadbed range section at present, be used in the requirement that to satisfy security performance on the works, and the cast-in-site wall fence security performance of bridge construction beyond the region of objective existence side is low, road not attractive in appearance scape is inharmonious, speed of application slow, later maintenance expense height.
Three. the content of utility model:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of novel in design unique, intensity is high, safety good and the novel wall fence for highway of long service life.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of novel wall fence for highway contains inboard preformed layer and outside cast in situs layer, and described inboard preformed layer is set in outside cast in situs layer, and described outside LIFT is formed by cage of reinforcement and concrete cast in situs.
Described inboard preformed layer is arranged side by side by prefabricated section and forms.
Be filled with macromolecule glue in the slit between the adjacent described prefabricated section.
The beneficial effects of the utility model are:
1, the utility model is made by the method that prefabricated guardrail panel and cast-in-site combine, have the intensity height, moulding is attractive in appearance, highly polished, adopt vibroplatform prefabricated in addition, avoid honeycomb, pitted skin, reduced the concrete pore rate of cast-in-site, improved the grade strength and the compactness of guardrail, thereby effectively improve the application life of guardrail, reduce later stage maintenance cost.
2, the utility model prefabricated section and cage of reinforcement are all made according to designing requirement in the processing space unification, and be transported to the job site then and carry out assembly unit, the construction of batch production production line, its high efficiency, cost of manufacture is low.
3, the utility model integrates numerous advantages such as short construction period, cost be low, is applicable to the making of multiple highway and Bridge guardrail, has good economic benefit after the popularization.
Four. description of drawings:
Fig. 1 is the structural representation of novel wall fence for highway.
Five. the specific embodiment:
Embodiment: referring to Fig. 1, among the figure, the inboard preformed layer 1 of novel wall fence for highway is set in outside cast in situs layer 2, and outside LIFT 2 is formed by cage of reinforcement 3 and concrete cast in situs.
Inboard preformed layer 1 is arranged side by side by a plurality of prefabricated sections and forms.And, be filled with macromolecule glue (not drawing among the figure) in the slit between contiguous prefabricated.
Its making step is:
A, site operation setting-out: according to construction design drawing, go out the inside and outside sideline of guardrail with total powerstation accurate setting-out on bridge hollow board, and along absolute altitude control point of the every 4-5 rice layout of inner edge, measure the elevation at each absolute altitude control point with level gauge, guarantee that the height of guardrail meets design requirement;
The installation of b, cage of reinforcement: according to the inner edge of the guardrail of site operation setting-out and the thickness of prefabricated section, on hollowcore slab, indicate the inner edge of cage of reinforcement with the line of ink marker, at a guardrail reinforcing bar of distance guardrail outer edge design protection layer thickness place with the outside control line of a line of ink marker as cage of reinforcement, the guardrail reinforcing bar is processed into semiproduct in the unification of reinforcing bar processing space according to code requirement, is transported to connect weldering with the prestressed cored slab reserved steel bar behind the job site and make type;
C, leveling layer is set: with the M12.5 mortar the wide leveling layer of 5cm is set along the guardrail inner edge on the hollowcore slab top;
D, prefabricated section and outboard template are installed: prefabricated section is in the unified processing of prefabricated processing space, be transported to the job site with transport vehicle, guardrail inner edge according to the site operation setting-out is provided with control line with cotton rope with the absolute altitude control point on the cage of reinforcement of guardrail upper end, with the elevation and the line style of this control line control prefabricated section; After the leveling layer mortar reaches certain intensity, by outside vertical columns and the outside horizontal support bar supporting outboard template is installed, with crane prefabricated section is lifted on the leveling layer then, after prefabricated section is just flat, install and fix the inboard vertical columns and the inboard horizontal support bar of prefabricated section, and prefabricated section and outboard template are closely connected into an integral body by the twice drag link of inboard vertical columns top and bottom, prefabricated section and outboard template are carried out essence put down by adjusting the drag link that is connected with inboard vertical columns and diagonal member;
E, concreting: at first water is moistening with hollowcore slab top and prefabricated section, use the bucket special of making according to guardrail width suitable for reading that the guardrail concrete is discharged in the guardrail template then, the guardrail concrete is built moulding at twice, for shortening the time interval of two-step pouring, each cover equipment that vibrates of front and back is constructed continuously;
F, health: after finishing, concreting in time covers with geotextiles, and the health of after concrete final set, sprinkling water;
G, piece are handled: after treating that the guardrail concrete reaches the intensity of design and code requirement, carry out the prefabricated section piece and handle.At first the cement mortar in the piece is rejected, with pencil and ruler the not straight suitable part of piece is marked then, subsequently according to the pencil line that indicates, with the small-size concrete cutting machine the not straight suitable part of piece is repaired, guarantee that piece is directly suitable up and down, seam is wide evenly, size is consistent, clog piece with macromolecule glue at last.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
