Abstract
The utility model relates to a glass-fiber reinforced composite manhole cover in the shape of the arch, which comprises a ring base and a cover. The ring base is a hollowed member mainly constructed by the glass-fiber BMC molded plastic. A plurality of vertical through-holes and/or blind holes are distributed on the bottom surface of the cover. The cover is in fixed connection with the upper portion of the ring base. A plurality of reinforcement ribs are arranged on the lower end of the composite manhole cover. The reinforcement ribs are in the structure of arch gradually lowered from the outer peripheral of the bottom of the composite manhole cover to the center, and an structure of arches gradually rising from the outer periphery of the top surface of the manhole cover to the center is provided on the upper surface of the manhole cover. Furthermore, reinforcement ribs are densely arranged onto the periphery ring portion of the manhole cover, and flexible filaments are filled into the periphery ring portion. The utility model is light in weight, great in mechanical performance, easy to be adhered to the concrete, unlikely to be overlapped, strong in bearing capability, and saves material. The abrasion resistance thereof is better than manholes in the prior art by far. Thus, the utility model is suitable for widely application for urban roads, squares, residential districts or the like.
Description
Technical field
The utility model relates to a kind of manhole cover, relates in particular to the compound manhole cover of a kind of glass enhancement mode arc.
Background technology
In the past, at the inspection shaft mouth, check that well head etc. locates to be provided with usually casting iron well lid, but this well lid cost is high, and is very heavy, and corrosion resistant not.For this reason, people are developed again and cement well lid, composite drain cover etc., but these well lids are if will have than large bearing capacity, then thickness must be very thick, so just cause the bulky heaviness of well lid, outside it, this class well lid is not if crush accidentally, then easily fall into inspection shaft or check well head, and then the vehicle on satisfying the need, pedestrian cause danger.
The utility model content
The purpose of this utility model is to propose the compound manhole cover of a kind of glass enhancement mode arc, and its weight is little, the intensity height, and bearing capacity is big, thereby has overcome deficiency of the prior art.
For achieving the above object, the utility model has adopted following technical scheme:
The compound manhole cover of a kind of glass enhancement mode camber, comprise walling crib and well lid, well lid is arranged on walling crib top, it is characterized in that: described walling crib is for mainly hollowing out member by what glass BMC moulding compound constituted, vertically through hole and/or blind hole of distributive plural on its bottom face.
Say further: described compound manhole cover lower end is provided with the complex root reinforcing rib, the arcuate structure of described reinforcing rib for being reduced gradually by circumferential center outside the described compound manhole cover bottom surface.
Described compound manhole cover upper surface has the arcuate structure that is raise gradually by circumferential center outside the described compound manhole cover upper surface.
The intensive reinforcing rib that is provided with in the flange portion of described compound manhole cover, and fill soft silk in the flange portion.
Vertical through hole more than two is set on the described well lid.
This case inventor is through studying for a long period of time and putting into practice, technology and application requirements according to product, adopt glass BMC moulding compound as main raw material(s), produce manhole cover, well seat, water grate, tree guard and other similar products through the high pressure mould pressing process at a certain temperature with excellent mechanical performances.
Adopt glass BMC moulding compound to be among the present invention:, in polymer, to optimize the important method that cross-linking system, curing system, interpolation reinforcer improve material property in technical field of polymer materials as the reason of main raw material(s).And as universal law, the bat wool material can effectively improve hot strength (having under the prerequisite of bonds well performance at filler and matrix resin) and rigidity (closely related with the draw ratio or the flakiness ratio of filler).If in the multicomponent mixed system, have crosslinking agent, initator, filler, form so-called hybrid structure and then can form multiple humidification with variform structure.The present invention adopts the different reinforcing materials of several character, structure and modulus such as bulk BMC filler, soft silk fiber, interlinkage reinforcing material to come modified unsaturated polyester, has realized the enhancing of unsaturated polyester (UP); Simultaneously, adopt the crosslinking agent (high surface elastic body micro mist is as anti-shrinking medium and flexibilizer) and the initator of new preparation, make BMC moulding compound curing system the degree of polymerization, press the place to obtain the modification and the raising of essence than, density.
Compared with prior art, the beneficial effects of the utility model are:
(1) walling crib adopts hollow structure, and this structure is alleviating walling crib weight, saving on the basis of BMC composite material, and walling crib more firm difficult rollover on ground, easier being stained with concrete are closed;
(2) compound manhole cover upper surface and bottom reinforcing rib adopt arc degree structure design, and this structure design makes well lid center stress point easier of diffusion all around, follows the flat well lid to compare, and the well lid intensity of arc degree and elasticity have increased by 1/3rd dynamics;
(3) flange adds soft silk in the compound manhole cover structure, reinforcing rib is encrypted design, and well lid flange abrasion resistance has been improved more than 2 times.
Description of drawings
Fig. 1 is the lateral view of the compound manhole cover of a kind of glass enhancement mode arc in the utility model specific embodiment;
Fig. 2 is the vertical view of the compound manhole cover of the enhancement mode arc of glass shown in Fig. 1;
Fig. 3 is the upward view of the compound manhole cover of the enhancement mode arc of glass shown in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment content of the present invention is further described.
Shown in Fig. 1～3, this manhole cover 1 is to adopt glass enhancement mode camber composite material to make through the high pressure mould pressing process, and it comprises walling crib 12 and well lid 11, and well lid 11 is arranged on walling crib 12 tops.
Wherein, described walling crib 12 is for hollowing out or partly hollow out member entirely, distributive plural vertical through hole and/or blind hole 122 on its bottom face.
Further, compound manhole cover lower end is provided with complex root reinforcing rib 121, the arcuate structure of reinforcing rib for being reduced gradually by circumferential center outside the compound manhole cover bottom surface; Simultaneously, compound manhole cover upper surface has by the circumferential arcuate structure 111 that raises gradually of center outside the compound manhole cover upper surface.
In addition, the intensive reinforcing rib that is provided with in the flange portion of compound manhole cover, and fill soft silk in the flange portion.
Be symmetrical arranged two vertical through holes 112 on the described well lid.
Above embodiment only is used to illustrate content of the present utility model; in addition; the utility model also has other embodiments; in every case those skilled in the art are because of the related technology enlightenment of the utility model, replace or technical scheme that the equivalent deformation mode forms all drops in the protection domain of the present utility model and adopt to be equal to.
