Abstract

The utility model discloses a reinforced manhole cover, which mainly comprises a flat iron frame, steel bars fixed on the flat iron frame and a non-metallic material filling layer filled in the flat iron frame for containing the steel bars, wherein, the filling layer is poured with a fibre cement mortar mixed layer, or fiber is directly mixed in the filling layer. The anti-crushing force and the abrasion resistance of the manhole cover are enhanced, and the reinforced manhole cover has high corrosion resistance, long service life and low cost. The rim edge angles of the manhole cover are not easy to break, and the utility model having the advantages of standard and beautiful appearance and convenient transportation, installation and maintenance is suitable for the public facilities of water supply, power supply, post telephone and telegraph, cables, China Unicom, China Mobile, etc.

Description

A kind of enhancing well lid

(1), technical field:

The utility model relates to a kind of well lid, relates in particular to a kind of enhancing well lid that is made of composite material.

(2), background technology:

The well lid of facilities such as water supply valve on the urban road and post and telecommunications, electric power and municipal administration generally adopts a kind of combined manhole cover, it is that the base-material of Main Ingredients and Appearance constitutes by skeleton with the Inorganic Chemicals, skeleton mainly is made of reinforcing bar and band iron framework, although this well lid is antitheft, but shortcoming is that anti-crushing force and antifraying force are poor, and is perishable.In addition, China's utility model patent manual discloses a kind of combined manhole cover, it by steel ring, be fixed on metal rib on the steel ring and be filled in the nonmetals packed layer that contains rib in the steel ring and form, this packed layer is made of glass fiber or steel fiber reinforced cement material, although this well lid mixes glass fiber or steel fibre in cement, anti-crushing force and antifraying force still are very poor.

(3), summary of the invention:

Technical problem to be solved in the utility model provides a kind of anti-crushing force and strong, the corrosion resistant enhancing well lid of antifraying force.

In order to solve the problems of the technologies described above, technical solution of the present utility model is such: this enhancing well lid by the band iron framework, be fixed on the reinforcing bar on the band iron framework and be filled in the band iron framework nonmetals packed layer that contains reinforcing bar and form, on this packed layer, be cast with fibre cement mortar mixed layer.

Above-mentioned packed layer is made of nonmetals and fibre.

Because the used metal material of the utility model well lid is few, in light weight.Be cast with fibre cement mortar mixed layer on packed layer, or directly fibre mixed in the packed layer, strengthened the anti-crushing force and the antifraying force of well lid, and had very strong decay resistance, the life-span is long, and is with low cost.Because inserts embeds the band iron framework, and high strength cast iron is arranged, intensity height, edge corner angle also are difficult for broken, and appearance standard, attractive in appearance, transportation, install, maintenance is convenient, urban operating mechanism such as be applicable to water supply, power supply, post and telecommunications, wired, UNICOM, move.

(4), description of drawings:

Fig. 1 is the structural representation that the utility model strengthens the well lid specific embodiment.

(5), the specific embodiment:

As seen from Figure 1, the utility model strengthens well lid and comprises band iron framework 1, is welded with plane net trellis reinforcing bar 2 in the framework 1, and other has two reinforcing bar embowments to become right-angled intersection to be welded on the steel ring, and camber is less than or equal to the height of band iron framework 1.Nonmetals can be multiple Inorganic Chemicals, also can be concrete, can also be glass fiber or steel fiber reinforced cement material, are filled in nonmetals in the band iron framework 1 and contain reinforcing bar 2 to constitute packed layer 3.Mix fibre in common cement mortar, constitute fibre cement mortar mixture, fibre cement mortar mixture is poured on the packed layer 3, just form fibre cement mortar mixed layer 4, its thickness is between 0.3cm-1.5cm.In addition, on well lid, have two through holes symmetrically, be easy for installation and maintenance.

The another kind of embodiment that the utility model strengthens well lid is, fibre mixed to be filled in the band iron framework 1 in the nonmetals and to contain reinforcing bar 2 constitute packed layers 3.On well lid, have two through holes equally symmetrically.

Claims

1, a kind of enhancing well lid, comprise the band iron framework, be fixed on the reinforcing bar on the band iron framework and be filled in the nonmetals packed layer that contains reinforcing bar in the band iron framework, it is characterized in that: on described nonmetals packed layer (3), be cast with fibre cement mortar mixed layer (4).

2, enhancing well lid according to claim 1 is characterized in that: described packed layer (3) is made of nonmetals and fibre.

2, enhancing well lid according to claim 1 is characterized in that: the thickness of described fibre cement mortar mixed layer (4) is 0.3cm-1.5cm.
