Abstract
The utility model relates to a protecting cover for corrosion protection of steel iron facilities in the ocean, river, lake and other waters is provided. The protecting cover covers the outer layer of the steel tubes, the cover is divided into lengthways two parts of main bodies, the main bodies are hemicycle with a symmetrical structure, and they are combined into be a bucket-shaped; the connecting parts of the two main bodies extent respectively outside and to form two flanges which are fixed each other by bolts. The utility model can prevent the steel iron facilities from corrosion, which are in the ocean, river, lake and other waters.
Description
Technical field
The utility model relates to a kind of iron and steel facility anticorrosion protective cover of protecting steel structure corrosion in the water bodys such as ocean, river and lake.
Background technology
Structure such as the platform of being built in water bodys such as ocean, river, lake, trestle, harbour, shore protection use steel pipe to make pile and crossbeam more; since steel pipe waves splash about the district the partial corrosion especially severe; so many external applications vaseline class; or, protect with protective cover again with after scribbling the putty that epoxy coating or epoxy resin are main component.Always employed organic protective cover, vertical direction are two semicircles of thickness homogeneous, and part also is same thickness near the flange, with two semicircular protective covers of bolt.There is following drawback in aforesaid protective cover: because the homogeneous of protective cover thickness; so with bolt with two protective covers fixedly the time; easily the flange position is deformed into Eight characters shape (referring to Fig. 3); cause near the casing deformation of flange; and make between protective cover and the steel pipe and to produce the gap 5., water just follows the crack and goes into to influence corrosion protection result.Have the fouling organism growth at gap location simultaneously, destroy anti-corrosion material, cause the protective effect of protective cover to be affected.
The utility model content
The utility model purpose provides a kind of protective cover of protecting steel structure corrosion in the water bodys such as ocean, river and lake.
Technical solutions of the utility model are: cover the steel pipe skin, vertically be divided into two-part main body, be semicircle symmetrical structure, fastening forms barrel-shaped, and the flange that its buckling parts extends to form separately laterally interfixes by bolt.Described symmetrical semicircle main body is structure thicker gradually to the wall thickness at flange position, and its body rim thickness can be the thick 3-4 in main body middle part doubly.Wherein: the material of main body is an admixture glass fiber in the unsaturated polyester resin; Its inboard adds foamed plastic or rubber buffering internal layer.
The utlity model has following beneficial effect:
Adopt protective cover of the present utility model; because the wall thickness at its two side flanges position increases gradually, so when tightening with screw, near the body rim the flange also can not be out of shape and be produced the space; and produced good sealing property for the steel pipe corrosion-proof topping, also be easy to simultaneously bolt tightening.In addition and since at the inboard lining of protective cover soft padded coaming, so both made steel surface former thereby uneven because of corrosion etc., its protection effect is also unaffected.Simultaneously, soft liner also can slow down the impact of external force to protective cover.

Fig. 1 is by nut and the fixing protective cover state plane figure of screw.
Fig. 2 is another view of protective cover installment state.
Fig. 3 fixes anticorrosion shell state plane figure for prior art with nut and screw.
Label is: 1. protective cover, 1a. main body, 1b. body rim, 2. flange, 3. screw, 4. nut, 5. gap, 6. cushion coat, 7. steel pipe.
The specific embodiment
Protective cover is used in the steel pipe corrosion-proof erosion, and it covers steel pipe 7 skins, and protective cover 1 is vertically divided equally for two parts main body 1a, is semicircle, and fastening then forms barrel-shaped; Its buckling parts extends to form flange 2 separately laterally, and is fixing by screw 3 and nut 4.The described two symmetrical semicircle main body 1a that vertically divide equally thicken gradually to the wall thickness at flange 2 positions, and its body rim 1b thickness can be the thick 3-4 in main body 1a middle part doubly (present embodiment is 3 times), and reaches maximum and homogeneous at flange 2 position thickness.As shown in Figure 1,1.5-3mm (present embodiment is 2mm) can be adopted in the size of present embodiment protective cover 1 each several part: main body 1a middle part; Flange 2 positions, promptly body rim 1b part can be selected 5-10mm (present embodiment is 7mm) for use.
In view of the water body environment in ocean, river and lake etc., for strengthening corrosion resistance and weatherability, the material of this main body 1a is an admixture glass fiber in the unsaturated polyester resin, and wherein the proportion scale of unsaturated polyester resin and glass fiber is a prior art.The liner padded coaming can be selected polyethylene, plastic foam material for use between main body 1a and the steel pipe 7.
Claims (3)
1. iron and steel facility anticorrosion protective cover is characterized in that: cover the steel pipe skin, vertically be divided into two-part main body, be semicircle symmetrical structure, fasten and form barrel-shapedly, the flange that its buckling parts extends to form separately laterally interfixes by bolt.
2. by the described iron and steel facility of claim 1 anticorrosion protective cover, it is characterized in that: described symmetrical semicircle main body is structure thicker gradually to the wall thickness at flange position, and its body rim thickness can be 3-4 times thick in the middle part of the main body.
3. by the described iron and steel facility of claim 1 anticorrosion protective cover, it is characterized in that: the material of main body is an admixture glass fiber in the unsaturated polyester resin; Its inboard adds foamed plastic or rubber buffering internal layer.
