Abstract
The utility model relates to a manhole cover, in particular to an improved manhole cover structure which is made of a composite material, and is aimed at devising a composite manhole cover with great intensity, even stressing and good stability. The above technique problem of the utility model is solved with the following technique proposal: the composite manhole cover manhole cover is composed of a reinforcement ring, a composite material piece to cover the reinforcement components, a reinforcement rail and a reinforcement montant connected to the lower edge of the reinforcement ring. Containing unsaturated resin, the composite material is strong and firm with no salvage value, therefore, it can guard against theft. The arrangement of the reinforcement rail and the reinforcement montant strengthens the firmness of the manhole cover.
Description
Technical field
The utility model relates to a kind of inspection shaft lid, especially relates to a kind of inspection shaft that the use composite material is made and covers isostructural improvement.
Background technology
At present, in urban road construction, be provided with and be convenient in a large number in inspection or the mediation, the inspection shaft of sewer or other underground utilities, these inspection shafts all need to build with cap seal, to guarantee the safety of pedestrian and vehicle.The inspection shaft lid that generally uses is at present still made by cast iron, but brittle fracture easily takes place and destroys in it, and because cast iron can melt down and make other products again, therefore the stolen phenomenon of well lid often takes place, in case occur just being easy to take place personal injury accident when well lid is lost and the end can in time be augmented again.Employing steel concrete that also has or glass fiber reinforced plastic are that main material is made the inspection shaft lid, though can be worth unmanned the pilferage because of no regeneration, but the well lid intensity with concrete for making is not high, the ribs of inner arrangement of reinforcement and bottom surface is provided with imperfection, the well lid edge easily produces broken and the slump phenomenon, and is that the well lid that material is made can be too light because of weight with glass fiber reinforced plastic, poor stability, vehicle by the time easily to produce string moving, even can have been rolled and broken away from walling crib.Chinese patent literature discloses a kind of composite material manhole cover (00235697.X), and it forms through hot press moulding with the terephthalic unsaturated polyester resin composite material, and its obverse and reverse all has reinforcing rib, and interior thickness is thicker than periphery, and outer border is taper; Inspection shaft is stamped two lockholes and sets up lock, and lockhole covers with the sealing mat card; Inspection shaft covers positive two places handle, and the reverse side periphery has a seal groove embedding sealing ring.But, make and the lid discontinuity rupture easily because its reinforcing rib is circular and radial vertical bar type.
The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, to design a kind of intensity height, and is stressed even, the composite material manhole cover of good stability.
Summary of the invention
The utility model mainly is that solution existing in prior technology inspection shaft lid intensity is not high, the technical problem of poor stability etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Composite material manhole cover of the present utility model comprises reinforced steel bar ring, covers the composite material of reinforcement component, it is characterized in that described reinforced steel bar ring lower edge is connected with reinforcing bar cross bar, reinforcing bar montant.Contain unsaturated-resin in the composite material, fastness is strong, does not have recovery value again, can be antitheft.Reinforcing bar cross bar, reinforcing bar montant are set, strengthen the fastness of inspection shaft lid.
Reinforcing bar montant and reinforcing bar cross bar can be connected to a plane, perhaps are cross-linked.As preferably, the reinforcing bar montant is connected below the reinforcing bar cross bar, to strengthen fastness and globality.
As preferably, reinforcing bar cross bar, reinforcing bar montant and composite material form raised line, to improve supporting capacity.
As preferably, the reinforcing bar cross bar becomes rectangle with the raised line cross section at reinforcing bar montant place, makes supporting capacity the best, and can economical with materials.
Therefore, the utlity model has characteristics such as rational in infrastructure, intensity height, good stability, pilferage durable in use and unmanned.
Description of drawings
Accompanying drawing 1 is a kind of structure vertical view of the present utility model;
Accompanying drawing 2 is a kind of structural profile schematic diagrames of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as accompanying drawing 2, this routine inspection shaft is stamped a reinforced steel bar ring 1, and ring is welded with the reinforcing bar cross bar 2 of four horizontal positioned down, and its adjacent two spacing equates, and the two ends of reinforcing bar cross bar 2 all are welded on the reinforced steel bar ring 1.The reinforcing bar cross bar is welded with the reinforcing bar montant 3 of four horizontal positioned for 2 times, and its adjacent two spacing also equates, cross bar and the welding of montant infall.The bar construction that welding is finished is put into mould, and the cross section of reinforcing bar cross bar, montant place groove becomes rectangle in the mould, fills the composite material 4 that contains unsaturated-resin, hot press moulding.
As accompanying drawing 1, after mold pressing is finished, the moulding of inspection shaft lid, the cross section of the raised line of routing up in the female mold tool all becomes rectangle, has effectively improved bearing capacity.
