Abstract
The utility model relates to a round manhole cover and cover seat with a welding framework, belonging to an accessory of the auxiliary construction of a municipal engineering of draining water, gases, etc. The manhole cover and the cover seat both comprise the framework and basal materials whose main element is inorganic materials, and the framework mainly comprises a steel bar and a flat iron frame. The consumption of the rolled steel of the manhole cover is little, and the cost is low, thus reaching the purpose of preventing the manhole cover from being missed. The utility model can be used in the municipal engineering of draining water, gases, etc.
Description
The utility model is a kind of round manhole cover, cage that welded framework is arranged, and belongs to the accessory of municipal engineering ancillary structures such as plumbing, coal gas.
It is investigated card: be used to show well lid, cages such as well, gate shaft, sink hole, gasser at present both at home and abroad and adopt iron casting more, its complex process, cost height, easy fracture, easily lose.Also useful steel concrete is made, and its rolled steel dosage is big, the volume heaviness, and easily unfilled corner is fallen rib.
The purpose of this utility model provides that a kind of cost is lower, and weight is lighter, has the round manhole cover that welded framework is arranged, the cage of higher impact strength simultaneously.
The purpose of this utility model realizes by following mode.
There are the round manhole cover of welded framework, the base-material that cage by skeleton with the inorganic raw material is Main Ingredients and Appearance to constitute.
Skeleton mainly is made of reinforcing bar and band iron framework.The well lid skeleton is welded mutually with the band iron framework by principal rod, distribution bar and constitutes.
Base-material adopts light magnesium oxide (MgO) and a certain amount of elasticity aglite such as wood sawdust or bamboo bits mix, adds certain density magnesium chloride (MgCl
26H
2O) solution mixes, and adds an amount of fiber reinforced material such as glass fiber again, fully stirs into the thick plastic of certain flowability.It is poured in skeleton or the mould, after vibrating, curing molding.
Well lid described in the utility model, cage compared with prior art have following advantage: 1, have certain elasticity and toughness, the resistance ability is good, the impact strength height.2, rolled steel dosage is little, cost is low, anti-lost.3, little, the non-environmental-pollution of power consumption.4, simple, the quick solidifying of rational in infrastructure, technology, in light weight, labor strength is low.
Below in conjunction with well lid is that the accompanying drawing of ribbed panel form is described in detail the utility model.
As shown in drawings: (1) is cage; (2) be well lid; (3) be well lid band iron framework; (3 ') are the pre-buried band iron framework of cage; (4) be principal rod; (5) be the cage reinforcing bar; (6) base-material; (7) be rib of slab; (b) do one section curved muscle of structure and band iron framework welding enlarged drawing for principal rod.As shown in the figure, well lid (2) and cage (1) are base-material (6) formation of Main Ingredients and Appearance by skeleton with the inorganic raw material.Skeleton mainly constitutes with reinforcing bar and band iron framework.The well lid skeleton is welded mutually with the band iron framework by principal rod, distribution bar and constitutes.Base-material adopts light magnesium oxide (MgO) and a certain amount of elasticity aglite such as wood sawdust or bamboo bits mix, adds certain density magnesium chloride (MgCl
26H
2O) solution mixes, and adds an amount of fiber reinforced material such as glass fiber again, fully stirs into the thickness plastic of certain flowability, it is poured in skeleton or the mould, and after vibrating, curing molding.
The principal rod of skeleton (4) is done one section curved muscle of structure and is welded mutually with band iron framework (3) at its edge.
The base-material surface layer can add an amount of mineral pigment and hard aggregate such as sand, also can add an amount of waterproof moisture proof agent in the base-material.The another kind of form of base-material is that cement is added elasticity aglite, fiber reinforced material and other waterproof reinforcing agents such as acrylics emulsion.
Well lid of the present utility model has flat type, can make the prestressing force form, preferably is made into the form of ribbed panel.Principal rod in the well lid rib of slab of ribbed panel form is done one section curved muscle of structure and is welded mutually with the band iron framework.
Claims (2)
1, a kind of round manhole cover, cage that welded framework is arranged is characterized in that: well lid (2) and cage (1) are that the base-material of Main Ingredients and Appearance constitutes by skeleton with the inorganic raw material, and skeleton mainly is made of reinforcing bar and band iron framework.
2, by right 1 described well lid, cage, it is characterized in that: the well lid skeleton has by principal rod (4), distribution bar and band iron framework (3) and welds formation mutually.
