Abstract
The utility model relates to a plastic composite manhole cover support which comprises a support framework of an annular structure, wherein plastic or foaming cement is filled in an annular cavity of the support framework, and a decorating veneering is pasted to the surface of the support framework. By means of the plastic composite manhole cover support, the stress bearing face of the manhole cover support is expanded, bearing capacity is improved, and the plastic composite manhole cover support is low in cost, practical and attractive.
Description
Technical field
The utility model relates to a kind of manhole cover bearing, relates to the compound manhole cover bearing of a kind of plastic cement specifically.
Technical background
The manhole cover bearing is all kinds of manhole covers are located load-bearing in actual applications as well lid special carrier.Tradition well lid bearing is general to adopt the material corresponding with the well lid quality to make.As: cement well lid water distribution mud bearing; The cast steel well lid is joined cast steel supporter; Resin man-hole cover is joined the resin bearing.There is following defective in actual applications in the well lid bearing that above-mentioned material is made:
One, above-mentioned manhole cover bearing, because a variety of causes ubiquity contact area is too small, the pressure that produces during the load pressure-bearing will certainly form certain destruction to well lid seat supports body, causes phenomenons such as the manhole oral area is crooked, sedimentation, all crackings of well.
Two, traditional manhole cover bearing is because due to the limitation of making material, the ubiquity presentation is not good.For example: the corrosion of cast steel well lid bearing is serious, and the well lid bearing that cement, rigid plastics and resin material are made, and easily produces mechanical injuries such as collapsing the limit, fall slag, be damaged.The well lid bearing of these materials making also exists weak point digestion period simultaneously, rolls for a long time to impact easily to produce the molecule fatigue fracture.
Three, traditional well lid bearing generally adopts the monomer braced structures, and bearing carrying flange is narrower, does not have and disperses pressure that effect should be arranged, and opposite narrow limit itself is more vulnerable to impact injury.Not only self can also can cause the well lid that is subjected to its protection chain impaired because of the external force deformation fracture.Also be to limit by the same token, traditional well lid bearing can not be done ornamental design at all, also just is far from being and beautifies the environment.
Summary of the invention
The purpose of this utility model is to overcome the defective of above-mentioned prior art, provides a kind of bearing capacity strong, low cost of manufacture, long service life, the compound manhole cover bearing of practical and attractive plastic cement.
The purpose of this utility model is achieved through the following technical solutions:
The compound manhole cover bearing of a kind of plastic cement is characterized in that: comprise the bearing skeleton of ring structure, be filled with plastic cement or foam cement in the toroidal cavity of described bearing skeleton, the surface is pasted with decorative faced.
Described bearing skeleton is circular, square or polygon.
The outer ring bottom of described bearing skeleton is provided with the right-angle side that turns up.
The interior ring of described bearing skeleton is provided with the well lid with punching press flange and is located Ka Tai.
Described decorative faced composite bed for adopting color plastic material, resin material or metal pattern molding lace to make.
The compound manhole cover bearing of the utility model plastic-steel has following technical characterstic:
One, the utility model well lid bearing; be to design according to the physical relation of lifting surface area and pressure; enclose the circle Combination Welding with steel section bar material by machinery; this technology has effectively been expanded the carrying stress surface of well lid bearing; well lid is done the pressure that produces man-hour discharge effectively and weaken, thereby protected the availability ratio that uses of manhole cover.
Two, the utility model well lid bearing can be filled to entity with the bearing internal cavities with foam cement or plastic material according to concrete instructions for use.So both satisfied the purpose that improves the goods bearing capacity, and can not make the cost of manufacture of well lid bearing too high again, the application of this material has simultaneously also formed the corrosion medium of metal product, and the oxidation cycle of bearing metal material and application life are prolonged.
Three, the utility model well lid bearing, owing to adopt the design of pressure-bearing broadside, in the bearing surface groove that the dicyclo hollow structure forms, but the filling color plastic material; Make matting; Inlay Sign Board or mold pressing character pattern etc.Make the well lid bearing satisfying under the function use prerequisite, play and beautify the environment, the artistic effect of enhanced feature product.
Four, the utility model well lid bearing can and use atmosphere according to customer demand, is made into the well lid bearing of square-outside and round-inside.The square outer rim of this bearing also can be made the card lifting platform, will block platform installation parallel to the ground like this when using, and can form the screens space of laying deckboard at original manhole base, conceals well lid with deckboard and sets off environment for use.If can be in the park, ground such as square, government bodies, tourist attraction is being equipped with excellent result of use.

Fig. 1 is the cross-sectional view of the compound manhole cover bearing of the utility model plastic cement.
Fig. 2 is the compound manhole cover bearing of the utility model plastic cement product vertical view.
Specific embodiments:
The compound manhole cover bearing of plastic cement of the present utility model comprises and adopts angle steel, band steel or square steel to circularize the bearing skeleton 1 of body structure by machinery circle circle Combination Welding, and the body shape of this bearing skeleton 1 is square, circle or polygon.Be filled with plastic material or foam cement 2 in the belt cavity of bearing skeleton 1, make it become solid, the top layer that forms after above-mentioned technology is finished is pressed into or is pasted with decorative faced 3.Described decorative faced 3 for adopting the composite bed of color plastic material, resin material or the making of metal pattern molding lace.Outer shroud bottom at above-mentioned bearing skeleton 1 forms the right-angle side 4 that turns up by punching press, is equipped with the well lid with punching press flange in it and is located card platform 5.
