Abstract
The utility model discloses a tough non-steel frame composite resin manhole cover, which comprises an upper cover and an outer ring, wherein the upper cover is placed on a step of an inner hole seam allowance of the outer ring, and the upper cover and the outer ring both include composite resins and platinum cloth interlayers which are arranged inside the composite resins and distributed separately from the composite resins. Composite resin surface layers are covered outside both of the upper cover and the outer ring; color image-text marking patterns are arranged on the composite resin surface layer covered on the upper portion of the upper cover; 1-20 layers of the platinum cloth interlayers can be distributed separately from the composite resins and inside the composite resins; and more platinum cloth interlayers are arranged when the load bearing force of the upper cover is larger than that of the outer ring. The manhole cover is produced by mixing specially prepared raw materials, tiling the materials and the interlayers, extruding, forming and demoulding. The manhole cover has fine toughness, long service life, low production cost, small one-time investment and no need of adopting expensive special press machines and special steel moulds. The manhole cover can be produced by adopting self-made simple press machines and self-made moulds, contains no metal materials, avoids rusting and can not be stolen, and the appearance design of the manhole cover can be changed from single-color characters into the various-color image-text marking patterns.
Description
Technical field
The utility model relates to a kind of compound resin well cover, and particularly a kind of tough steel frame-free compound resin well cover belongs to road pipe network ancillary facility.
Background technology
Continuous development along with national economy and society, domestic city infrastructure progress rapidly, the road pipeline network construction constantly enlarges, the well lid demand that pipe network disposed significantly increases, the tradition well lid is casting iron well lid or cement well lid, because casting iron well lid is easily stolen, and heavy and corrosion easily, progressively withdrawing from the market in the nineties in last century is replaced by compound resin well cover.Existing compound resin well cover normally adopts the compound resin internal layer to add steel frame and makes, though this goods rigidity is pure, and poor toughness, very easily broken and damage; The steel frame that internal layer plays booster action is corroded easily, waits to erode to and to a certain degree can cause intermediate gaps to rot and damage; It is many to produce the disposable input of compound resin well cover, needs expensive special pressure machine and special steel mould, the cost of production height; For the compound resin well cover of enhancement mode, because its steel frame is greatly also stolen easily, losing of well lid tends to cause serious personal injury and economic loss.
The utility model content
The utility model is developed a kind of tough steel frame-free compound resin well cover targetedly in order to solve the existing technical problem of above-mentioned existing compound resin well cover, can improve the toughness of compound resin class well lid, increases the service life, and reduces production costs.
The technical solution adopted in the utility model is as follows:
This tough steel frame-free compound resin well cover comprises loam cake and outer ring, and loam cake places on the step of outer ring endoporus seam, and the upper surface of the two maintains an equal level.Described loam cake comprises compound resin and platinum cloth interlayer inner spaced apart with it thereof, and the outer ring also comprises compound resin and platinum cloth interlayer inner spaced apart with it thereof.
Described loam cake and outside, outer ring all cover the compound resin surface course.
The compound resin surface course that described loam cake top covers is manufactured with one or more color picture and text sign picture case.
The inner platinum cloth interlayer that is distributed with the 1-20 layer with interval of described compound resin.Loam cake is because its load-bearing is stressed big, and contained platinum cloth interlayer is many in the compound resin, and the outer ring is stressed less than loam cake owing to its load-bearing, and its platinum cloth interlayer can suitably reduce.
Produce raw material that this well lid adopts special preparation through the operations such as material and interlayer, extrusion modling and the demoulding that mix, tile.
Tough steel frame-free compound resin well cover beneficial effect: tough steel frame-free compound resin well cover good toughness, long service life, cost of production is low, and disposable less investment, need not adopt expensive special pressure machine and special steel mould, employing is made simple press by oneself and can be produced from molding jig; In addition, this well lid is the containing metal material not, and not corrosion can be not stolen; The well lid appearance design can change monochromatic character and indicate pattern for the multicolour picture and text.
Description of drawings
Fig. 1 is the front view of tough steel frame-free compound resin well cover;
Fig. 2 is the sectional drawing of tough steel frame-free compound resin well cover.
The specific embodiment
Further introduce embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, this tough steel frame-free compound resin well cover comprises loam cake 1 and outer ring 2, and loam cake 1 places on the step of outer ring 2 endoporus seams, and the upper surface of the two maintains an equal level, and one is embedded in the pipe network well head and keeps in one plane with ground.
No matter be that loam cake 1 or outer ring 2 external surfaces all cover the compound resin surface course.
For loam cake 1, the compound resin surface course that its top covers is manufactured with one or more color picture and text sign picture case 3.
This well lid comprises loam cake and outer ring, and the raw material proportioning and the production craft step of its all kinds of model specification products are as follows:
(1) raw material mixes preparation raw material resin 5-30%, calcium powder 50-70%, polystyrene 1-3% (needing first heat fused), quartz sand 10-25%, mixing and stirring in the containers of packing into such as short yarn cutting 2-3% can add accelerator and curing compound in right amount according to temperature condition;
(2) tiling mixed material and interlayer are at the mixed material of mixing from molding jig middle berth last layer last process, add one deck by the good platinum cloth of the big cabinet of product area, spread a layered material then and add one deck platinum cloth, can spread 1-20 layer platinum cloth, be paved with one deck mixed material at last, buckle well mould, add screw and fix;
(3) extrusion modling is put under the self-control forcing press, and the normal temperature extruding got final product in two minutes;
(4) demoulding is left standstill the demoulding after 30-120 minute at temperature 10-40 Celsius ℃.
According to the difference of compound resin raw material proportioning with and what of inner platinum cloth interlayer spaced apart with it, can obtain to carry the tough steel frame-free compound resin well cover of 2-30 ton weight.
Generally, the size of well lid weight capacity is relevant with the compound resin composition of raw materials, and how much relevant with the platinum cloth interlayer in the compound resin, under compound resin is filled a prescription constant situation, platinum cloth interlayer in big then its compound resin of the weight capacity of well lid is many, otherwise then few.Moreover because the loam cake load-bearing is stressed greater than the outer ring, the composition of raw materials of loam cake and platinum cloth interlayer are had relatively high expectations, and can adopt unified or different prescriptions and interlayer, but require the weight capacity of the weight capacity of loam cake greater than the outer ring.
Above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model, in the ken that described field those of ordinary skill is possessed, can also make various variations under the prerequisite that does not break away from aim of the present invention.
