Abstract
The utility model relates to a well lid, in particular to a glass fiber reinforced plastic well lid which is low in weight, low in manufacturing cost, high in compressive strength, not prone to fragmentation and long in service life. The glass fiber reinforced plastic well lid comprises a metal frame, wherein a glass fiber reinforced plastic plate is arranged on the upper surface of the metal frame, or glass fiber reinforced plastic plates are arranged on the upper surface of the metal frame and the lower surface of the metal frame respectively.
Description
Technical field
The utility model relates to a kind of well lid, relates in particular to a kind of glass fibre reinforced plastic manhole covers.
Background technology
Well lid is for covering sewage, rainwater, and electric power, feedwater, the daily object of the pipeline maintenance management points such as coal gas, it usually is located on the road and the place of vehicle, pedestrian's process is arranged.Existing well lid is distinguished by material, and metal well lid, cement-base composite material well lid, regenerating resin base composite material manhole cover are arranged usually, but existing well lid all has shortcoming separately, and the metal well lid is heavy, and cost is high, and difficulty is installed; It is low, cracked easily that cement based meets the material well lid, the regenerating resin base meets material well lid compressive strength, and application life is short.Now be badly in need of a kind of lightly, cost is low, and compressive strength is high, and not easily broken well lid substitutes existing well lid.
Summary of the invention
Therefore, for above-mentioned problem, the utility model proposes that a kind of weight is light, cost is low, compressive strength is high, the glass fibre reinforced plastic manhole covers of not easily broken, high life.
For achieving the above object, the utility model has adopted following technical scheme: glass fibre reinforced plastic manhole covers, the upper surface that comprises metal framework, described metal framework is provided with or upper and lower surface is respectively equipped with glass epoxy.
Further, relatively be provided with evenly distributedly more than one support steel bar between the side plate in the described metal framework.
Further, the described steel bar that respectively supports is arranged by the mode of right-angled intersection.
Further, be provided with evenly distributedly on the glass epoxy of described upper surface a plurality of for anti-skidding projection.
Further, the lateral surface of described metal framework is provided with more than one handle for conveniently lifting.
Further, described metal framework is rectangle.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: compare with existing well lid, this glass fibre reinforced plastic manhole covers utilizes metal framework for supporting, thereon the surface or upper and lower surface coverage upper glass steel plate, its weight is alleviated greatly, and cost reduces, and compressive strength is also larger, not easily broken, long service life; Further, in metal framework, relatively be provided with evenly distributedly more than one support steel bar between the side plate, the compressive strength of glass fibre reinforced plastic manhole covers is increased; Further, on the glass epoxy of upper surface, be provided with evenly distributedly a plurality of projections, increased the frictional force of well lid, play anti-skidding effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the stereogram of glass fibre reinforced plastic manhole covers.
The specific embodiment
Now with the specific embodiment the utility model is further specified by reference to the accompanying drawings.
With reference to figure 1, Fig. 2, present embodiment provides a kind of glass fibre reinforced plastic manhole covers, comprises that the upper and lower surface of rectangle metal framework 1, described metal framework 1 is respectively equipped with glass epoxy 2.Be provided with evenly distributedly along its length six support steel bars 3 between the described metal framework 1 interior relative side plate, broad ways is provided with two support steel bars 3 evenly distributedly between the described metal framework 1 interior relative side plate, and the support steel bar 3 of described length direction and width is arranged by the mode of right-angled intersection.Be provided with evenly distributedly a plurality of for anti-skidding projection 4 on the glass epoxy 2 of described upper surface.Be respectively equipped with two the handle 5 conveniently lift of being used on the described metal framework 1 two relative lateral surfaces along its length.
Compare with existing well lid, this glass fibre reinforced plastic manhole covers utilizes metal framework for supporting, and surface or upper and lower surface coverage upper glass steel plate alleviate its weight greatly thereon, and cost reduces, and compressive strength is also larger, not easily broken, long service life; Further, in metal framework, relatively be provided with evenly distributedly more than one support steel bar between the side plate, the compressive strength of glass fibre reinforced plastic manhole covers is increased; Further, on the glass epoxy of upper surface, be provided with evenly distributedly a plurality of projections, increased the frictional force of well lid, play anti-skidding effect.
Above-mentioned metal framework also can use the shapes such as circle, triangle, polygon to replace according to actual needs; Above-mentioned projection also can be arranged to groove.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
