Abstract

The utility model relates to a glass fiber reinforced plastic manhole cover for catch basins, which comprises a cover body shaped by glass fiber reinforced plastic material, a seat ring matched with the cover body, and a cover body skeleton composed of steel reinforcement, wherein a supporting beam of the cover body, which is arranged in radial direction and matched with a supporting opening of the seat ring, is arranged below the cover body and shaped into a whole with the cover body, and reinforcing ribs of the supporting beam are provided and matched with the supporting beam. The cover body structure that the reinforcement supporting beam is arranged on the lower part is used in the utility model, and the matching of the supporting beam and the seat ring is used as load bearing support of the cover body to realize the aim that less material is used correspondingly for achieving higher carrying capacity. Compared with the existing similar glass fiber reinforced plastic manhole cover, the utility model has the advantages of strong carrying capacity and low cost. Because the resin, the glass fiber and the quartz sand are used as principal raw material, auxiliary raw material such as reinforcing agent, etc. is added, and the mould shaping and casting technology is used, the utility model is suitable for scale production mode and has the advantage of low cost, and the product can be ensured to have the strength, the toughness, the wear resistant property and the ageing resistance which fully satisfy the operating requirements.

Description

Glass fibre reinforced plastic manhole covers
Technical field
The utility model relates to the civic building facility, is a kind of inspection shaft glass fibre reinforced plastic manhole covers specifically.
Background technology
Inspection shaft be used in upper and lower water course or other underground pipeline projects to check or dredge must establish building owing to be arranged on the road mostly, therefore require well lid that enough intensity and abrasion resistance are arranged.Traditional Cover of inspection well is made of cast iron lid and cast iron seat ring, and is easily stolen because of the material reproducible utilization, and the inspection shaft of having lost well lid can constitute greatly passing pedestrian and vehicle and threatens.For solving the problem that the metal well lid is easily lost, prior art discloses several glass fibre reinforced plastic manhole covers, but owing to all adopt the lower limb of lid to prop up the load-carrying members that mouth cooperates with seat ring, cause the supporting capacity of lid not high, be difficult to satisfy heavily loaded instructions for use, and, cause the cost of production of well lid too high owing to used too much material.
Summary of the invention
The purpose of this utility model is the problems referred to above at existing glass fibre reinforced plastic manhole covers existence, and provides a kind of supporting capacity strong, uses the few glass fibre reinforced plastic manhole covers of material relatively.
The technical scheme that realizes above-mentioned purpose is: a kind of glass fibre reinforced plastic manhole covers, the lid skeleton that includes lid that adopts the glass-reinforced plastic material moulding and the seat ring that cooperates with it and form by reinforcing bar, below its lid, be provided with by radial arrangement and with seat ring and prop up the lid brace summer that matches of mouth, be provided with the brace summer reinforcing rib with the brace summer phase configuration with the lid global formation.
The technical solution of the utility model also comprises: described brace summer is a center line by the five equilibrium angle uniform three with the lid diameter line; The reinforcing rib of described brace summer is connected to form by two reinforcing bars up and down that place beam center line vertical plane respectively, the last reinforcing bar of each reinforcing rib is straight shape, join in the lid centre point and to cross, the following reinforcing bar of each reinforcing rib is arranged to straight shape, downwarp shape respectively, is gone up arch, and not joining in the lid centre point crosses; A mouth of seat ring is provided with the brace summer embedded groove.
The utility model adopts the cover body structure that the reinforcement brace summer is set below, and cooperate with seat ring as the load-bearing of lid by brace summer and to support, thereby effectively improved the force-bearing situation of well lid, realized using relative less material to reach purpose than high bearing capacity, compare with existing glass fibre reinforced plastic manhole covers of the same type, it is strong to have supporting capacity, the characteristics that cost of production is low.

The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing, the utlity model has the disc lid 1 that adopts the glass-reinforced plastic material moulding and with the seat ring 2 in the T-shaped cross section of lid configuration, on lid 1, be symmetrically arranged with the handle hole of uncapping, ring stiffener is set in the seat ring 2 as requested.Be provided with by steel hoop, circular arc reinforcing bar and the lid skeleton 3 formed of reinforcing bar radially with the lid phase configuration, below lid, be provided with by radial arrangement and with seat ring and prop up a mouthful lid brace summer 4 that matches with the lid global formation.As accompanying drawing embodiment, lid brace summer 4 is center line with the lid diameter line preferably and evenly arranges three by the five equilibrium angle, can select when specifically implementing trapezium structure is arranged in the longitudinal and transverse cross section of brace summer, to adapt to its force-bearing situation, improves the supporting capacity of beam.Match with brace summer and to be provided with brace summer reinforcing rib 5, during concrete enforcement, the reinforcing rib of each brace summer is made of continuous two reinforcing bars up and down that place lid diameter line vertical plane respectively, the last reinforcing bar of its each reinforcing rib is arranged to straight shape, and join in the lid centre point and to cross, the following reinforcing bar of each reinforcing rib is arranged to as the straight shape of accompanying drawing 4, accompanying drawing 5, accompanying drawing 6, downwarp shape respectively, is gone up arch, is not join in the lid centre point to cross.The configuration structure of above-mentioned brace summer and reinforcing rib can effectively improve the force-bearing situation of well lid, gives full play to the load-bearing characteristic of structure, when reducing material and using, improves the supporting capacity of well lid.
When lid of the present utility model and seat ring assembling, the lower plane of available support beam end and seat ring prop up the bearing capacity fitting face of mouthful platform plane as lid and seat ring.Also can provide as accompanying drawing, on a mouth of seat ring 2 brace summer 4 embedded grooves 6 are set, through brace summer and cooperating of caulking groove lid is assemblied on the seat ring, this kind assembly structure helps improving the stability that lid cooperates with seat ring.
This glass fibre reinforced plastic manhole covers with resin, glass fiber, quartz sand as primary raw material; add auxiliary materials such as reinforcing agent; adopt the die casting moulding process; be not only applicable to the large-scale production mode; enhance productivity; reduce cost, can also guarantee that product has intensity, toughness, anti-wear performance and the ageing resistace that fully satisfies instructions for use.
The utility model is convenient to add toner in raw material, and produces the well lid of different colours, so that differentiation and identification between the different purposes well lid.
