Abstract
The invention discloses a reinforced manhole cover plate of which the upper part is provided with stainless steel plates. The reinforced manhole cover plate comprises angle steel with a pre-embedded entablature, wherein the angle steel is arranged on the upper edge of the wall of a manhole and is used for placing a concrete cover plate, a channel steel covered edge is arranged on the side surface of the concrete cover plate, channel steel and a rebar mesh are integrally welded, both ends of the concrete cover plate are respectively provided with one handle used for moving the concrete cover plate, a stainless steel cover plate is arranged on the top of the concrete cover plate, upturned stainless steel angle steel is welded around the stainless steel cover plate, so as to be connected with the stainless steel cover plate into a whole, and four drilled triangular stainless steel plates for lifting are welded on the stainless steel angle steel. The reinforced manhole cover plate has the advantages that the external corner of the entablature at the upper edge of the manhole can be effectively protected by the angle steel, the deformation of the cover plate due to concrete vibration and the damage to edges and corners during transportation can be prevented by the channel steel covered edge, the quality and use performance of the cover plate are good, the cover plate is convenient to transport and move, the working efficiency is high, additionally, the landscape requirement is satisfied, the installation is simple and convenient, and materials and labor are saved.
Description
Technical field
The present invention relates to a kind of pipe trench manhole cover plate, be particularly useful for higher to the requirement of lid surface view and that security performance is higher all kinds of manhole cover plate and cable channel cover plate.
Background technology
Along with the development in city, large-scale square, park, Applied in Business Pedestrian Street etc. are more and more, people are to the layout of these establishment landscapes and require also more and more higher, but the concrete manhole cover plate of traditional underground utilities, pipe trench is but arranged very inharmonious with the modern view such as surrounding ground marble guidance tape, wood flooring, but can not lack again these provides convenient and the pipeline of various function and the necessary attached manhole cover plate of pipeline.
Traditional reinforced concrete cover plate is after reinforced mesh colligation completes, assembled formwork, concreting is prefabricated again forms, during dimensional errors, vibrated concrete due to model sheetinstallat template deformation and form removal etc. all can cause that cover plate is out of shape, side out-of-flatness or corner angle damaged, add rehandling cover plate, more easily cause corner angle damaged, directly affect quality and the impression quality of cover plate.This cover plate is due to strength deficiency, and after load is stressed, being originally that crack, the breakage of cover plate corner angle appear in concrete cover flexural deformation, is then that concrete comes off, reinforcing bar is exposed, is finally that cover plate entirety destruction is caved in, causes very large potential safety hazard to pedestrian.
Summary of the invention
The technical issues that need to address of the present invention are, design the manhole cover plate that a kind of reinforced cover plate top arranges corrosion resistant plate, both the bend resistance ability of cover plate can have been improved, on the cover board can inlay again identical material of mating formation with cover plate periphery, manhole is overhauled convenient, and coordinate mutually with surrounding landscape, meet view requirement.
Technical scheme of the present invention is: a kind of reinforced cover plate top arranges the manhole cover plate of corrosion resistant plate, comprise and be arranged on angle steel pre-buried along the entablature for placing concrete cover on manhole wall, concrete cover side arranges channel-section steel bound edge, channel-section steel and reinforced mesh integral solder, concrete cover two ends respectively arrange a handle for transportable concrete cover plate, described concrete cover top arranges one deck stainless steel cover plate, the stainless steel angle steel that the surrounding welding of described stainless steel cover plate is turned over and described stainless steel cover plate connect into entirety, described stainless steel angle steel welds four triangle corrosion resistant plates with holes for lifting.
Advantage of the present invention is: adopt the technology of the present invention; water (block) when building manhole; manhole wall places the concrete entablature of concrete cover, the pre-buried angle steel being welded with iron supporting leg before building along building, and angle steel can along the external corner of entablature on available protecting manhole.When concrete cover is prefabricated, the reinforced mesh of concrete cover is fixing more accurately to be facilitated, the channel-section steel bound edge adopted replaces original template, and when can prevent the cover plate distortion that causes due to concrete vibrating and carrying, corner angle are damaged, cover plate quality and functional performance better.Movable cover plate when two handles arranged can conveniently be carried and overhaul, operating efficiency is higher.Concrete cover is provided with stainless steel cover plate, just can inlays identical material of mating formation with cover plate periphery on stainless steel cover plate, meet view requirement.During manhole maintenance, stainless steel cover plate and above pavement material thereof can integral hoistings, the operation of eliminate dismountings, again laying, and save material, manually.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
As shown in Figures 1 to 7, the present invention mainly comprises concrete cover (2), channel-section steel (21), handle (23), corrosion resistant plate (3), triangle corrosion resistant plate with holes (33).
Along building the concrete entablature placing concrete cover (2), the pre-buried angle steel (11) being welded with iron supporting leg (111) before building on manhole (1) wall, angle steel can the external corner of available protecting manhole entablature.
Setting-out cutting channel-section steel (21), the channel-section steel leg on the corner intersected cuts into 45
0angle, then the channel-section steel (21) of concrete cover (2) three sides is welded into entirety, assembling reinforcement mesh sheet (22), steel bar end is connected with channel-section steel (21), finally uses last side of channel-section steel (21) closed concrete cover plate.When precast concrete cover (2), the preformed hole of reserved handle (23), preformed hole adopts PVC plastic pipe (234) to be embedded in concrete, reserved notch (235), the placement of handle (23) when keeping flat for concrete cover (2), makes handle (2) and concrete cover (2) at grade.Handle (23) is made up of circular screw rod (231), nut (232) and iron plate pad (233), after concrete cover (2) maintenance completes, can penetrate handle (23) before use, to facilitate transportable concrete cover plate (2).
Stainless steel cover plate is made up of corrosion resistant plate (3), stainless steel angle steel (31) and triangle corrosion resistant plate with holes (33), stainless steel angle steel (31) turns over form on adopting and corrosion resistant plate (3) is welded into entirety, the upper welding four triangle corrosion resistant plate (33) with holes of stainless steel angle steel (31).At the upper some band irons (32) of laying of mounted concrete cover (2) as isolation, identical material of mating formation with cover plate periphery just can be inlayed, to meet view requirement the corrosion resistant plate plate (3) of installation is upper.Only need penetrate wire rope during manhole maintenance in four triangle corrosion resistant plates (33) with holes and get final product integral lifting stainless steel cover plate and pavement material, then transportable concrete cover plate (2) just can overhaul, and recovers after having overhauled by original state.
Below only just the present invention preferably example be described, but can not be interpreted as it is limitations on claims.The present invention is not only confined to above example, and its concrete structure allows to change, and those skilled in the art can make various change and distortion according to the present invention, only otherwise depart from spirit of the present invention, all should belong to the scope that claims of the present invention define.
