Thus, the water grate can be compared with a cast iron water grate completely, and the water grate has the advantage of convenient installation, the advantage that the water grate can not be stolen because of no reuse value, etc. The utility model is a high compressive strength drainage water grate of composite materials.

Description

High strength road drainage water grate

The utility model relates to the water grate of a kind of road, square draining.

Existing road drainage water grate is mainly by cast iron casting and concrete prefabricated forming, and cast iron water grate is often stolen, and causes the potential safety hazard of pedestrian and driving; Concrete prefabricated water grate has certain fragility, is easily crushed by vehicle and discards.Patented technology that CN97210207.8 discloses a kind of " composite material shutter grate ", single cover plate is made up of top layer and bearing course, adds the beam type bar frame in bearing course.Its top layer is mixed and stirred and is formed by pigment powder, high-strength cement or spherical cement, water, its bearing course is mixed and stirred and is formed by steel fibre, high-strength cement or spherical cement, granite or limestone pellet, silica flour or flyash, water, water reducing agent, obviously the nest mortar of the difficult dehydration of this patented technology mud prefabricated component.The water grate has only cover plate, does not have supporting grate seat, and is influential to road construction speed.

The purpose of this utility model design at the deficiencies in the prior art a kind of do not have recycle to be worth and to be difficult for stealing, have suitable toughness, resistance to pressure strong, the road drainage water grate that grating and grate seat are supporting.

The purpose of this utility model can realize by following measure: it is made up of grating and grate seat two large divisions, and drain hole is arranged on the grating, is embedded with reinforcing bar in grating and the grate seat, the grate seat by the frame between housing, inside casing and the interior housing along forming.

The utility model can come perfect by following measure:

Reinforcing bar in the grating divides three layout layers, the upper strata between each drain hole, parallel distribution with drain hole, the middle level is in the both sides and the intermediate distribution of grating, and is vertical with top reinforcement, lower floor distributes between two parties in length and breadth in the grating bottom; The reinforcing bar that buries in the grate seat has the positioning bar between outer ring, inner ring and two circles; Between the housing of grate seat and the frame edge triangle tractive piece is arranged.

Fig. 1 is the utility model surface structure stereogram.

Fig. 2, Fig. 3 are the A-A sectional view of Fig. 1.

Fig. 4, Fig. 5 are respectively grating, grate seat reinforcing bar Pareto diagram.

The utility model is below in conjunction with embodiment and contrast accompanying drawing and described in detail: this water grate is with unsaturated-resin and auxiliary material thereof, in bury reinforcing bar, form through heating and mould pressing.Integral body is divided into grating 6 and grate seat 1 two large divisions, and drain hole 5 is arranged on the grating 6, grate seat 1 by housing 2, inside casing 7, and in frame between the housing 2 and 7 form along 3, it is square that the water grate mostly is greatly, is many with rectangle especially, for beautifying needs, other geometry also can be made.Be that example illustrates now with rectangle water grate, the length of grating 6 is respectively 40 * 40 * 2.5 (units: cm, down together), the length of grate seat 1 housing 2 is 50-60 * 40 * 2, frame is 5 along 3 height, therefore the overall height of grate seat 1 is 7, frame along the length of 3 inner edges with wide should with the length of grating 6 and wide consistent.Inside casing 7 is in order to shelve grating 6.Drain hole 5 on the grating 6 can be arranged by common double parallel, bury reinforcing bar 8 in the composite material between the Kong Yukong (being unsaturated-resin and auxiliary material thereof), from guaranteeing intensity and saving cost consideration, reinforcing bar 8 adopts the standard thread steel, use Φ's 22 at main origin of force, intensive place uses Φ's 10, and the wire rod of non-main origin of force and the available Φ 6.5 in corner bevelling place is for it.The reinforcing bar 8 of grating 6 can be arranged the 3-4 layer, the upper strata comes between each drain hole 5, is arranged in parallel, and the middle level comes grating 6 both sides with middle, with the top reinforcement vertical arrangement, lower floor can be rich font and arrange in the grating bottom, or two horizontal vertical setting of types row, (the foursquare cross arrangement that is), consider the reinforcing bar number that this is horizontal with perpendicular with the length of grating 6 in a word, its principle is segmentation or whole arrangement placed in the middle, enables equilibrium and bears pressure.From grate seat 1 stressing conditions, can bury all reinforcing bars in each in housing 2 and inside casing 7 bottoms, with spacer bars tractive location, these reinforcing bars can be welded in the frame shape and be embedded in unsaturated-resin and the auxiliary material thereof therebetween.Triangle tractive piece 4 is also formulated when molding, is located at housing 2 and frame between 3, is also formed by unsaturated-resin and auxiliary material integral body thereof mold pressing together.The water grate of other geometry, the shape of its drain hole and arrangement can make dispositions according to firm, practical, attractive in appearance principle again, and the reinforcing bar layout of burying in it also can be done corresponding change, and these do not need can draw with creative work, do not give unnecessary details for this reason.Composite material is by 13-15 weight portion unsaturated-resin, and 18-25 part reinforcing agent, 0.1-0.2 part curing compound, 1-2 part release agent, 40-60 part filler etc. are mediated in kneader and formed.Raw material is pulvis, solvent, tight in the presswork, and structure is tight.

The base-material of this water grate is that unsaturated-resin and auxiliary material heating and mould pressing thereof form, in bury the standard thread steel, grating and grate seat form a complete production network, easy for installation, crushing resistance is strong, is difficult for brokenly, regeneration is worth low and is not stolen.Product (CJ/T3012-93) is tested with reference to Ministry of Construction's industry standard " castiron well cover " through building engineering quality supervision inspection post, Zhejiang Province, and cracking load reaches 240-250KN, and rupture load reaches 365-380KN, meets heavy well lid class requirement.
