Description
Technical field
This utility model relates to equipment and installs and technical field of anticorrosion, particularly relates to a kind of foundation bolt anticorrosion structure.
Background technology
When metal is placed in atmospheric environment, its surface would generally form the dampness film (moisture film) not easily seen a layer very thin.When this layer of moisture film reaches 20-30 molecular thickness, it reforms into the electrolyte membrane required for electrochemical corrosion.The formation of this electrolyte membrane, or due to the Direct precipitation of moisture (rain, snow), or the cohesion that causes of the humidity of air or variations in temperature and other various reasons and formed.In coastal area, due to sea wind action, being mingled with substantial amounts of salt granule in air, therefore metal erosion main manifestations in coastal area is atmospheric corrosion, and China southeastern coastal areas generally have the environmental quality of high temperature, high humidity and sunshine-duration length, exacerbate again the seriousness of atmospheric corrosion.
Being usually used in the foundation bolt that equipment installs at present and do not take effective anti-corrosion measure, what have simply protects exposing surface smear slushing oil such as yellow drier oil, but yellow drier oil air-dry after will soon lose safeguard function.
The Chinese patent that application number is 2012200096487.4 (applying date is on March 15th, 2012) discloses one " foundation bolt protective cover ", adopt nut protection body and the integrated cover body of screw rod protection body, and in cover body, fill anticorrosion oils and fats, screw rod protection body inwall is provided with screw thread, can be screwed on the screw thread that foundation bolt exposes, tighten rear protecting cover body to fit tightly with plane on the plain washer on foundation bolt, the water in running environment, vapour is made to cannot be introduced into, it is ensured that it uses for a long time in rugged environment.This scheme is general anticorrosion oils and fats due to what fill, and peripheral hardware protective cover, is relatively specific for rain, general atmospheric corrosion environment that snow is formed descends, but for maritime climate, it does not still possess good protective.It addition, its protective cover housing is on the plain washer of foundation bolt, once plain washer generation corrosion and damage, it will destroy integrally-built seal so that it is safeguard function is substantially reduced.
Summary of the invention
This utility model provides a kind of foundation bolt anticorrosion structure, foundation bolt component surface all brushing oiliness anticorrosive paint, and exposed parts is all placed in protective jacket, the lute in putty filled between foundation bolt component and protective jacket has inorganic acid resistance, alkali, salt corrosion, will not solidify or harden in-50 DEG C～110 DEG C temperature ranges characteristic, and there is good insulating properties；Foundation bolt can be played protective action well, be very suitable for using in coastal area.
In order to achieve the above object, this utility model realizes by the following technical solutions:
A kind of foundation bolt anticorrosion structure, including foundation bolt component, the foundation bolt bottom in described foundation bolt component is embedded in basis, and top sponson is set with packing ring and nut；Described foundation bolt sponson and packing ring, nut overcoat are equipped with protective jacket integrally, and foundation bolt, nuts and washers outer surface are all provided with oiliness anticorrosive paint layer, and be filled with a sealing between protective jacket and foundation bolt component clay putty.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Seeing Fig. 1, be structural representation of the present utility model, this utility model one foundation bolt anticorrosion structure, including foundation bolt component, foundation bolt 1 bottom in described foundation bolt component is embedded in basis 6, and top sponson is set with packing ring 5 and nut 4；Being set with protective jacket 2 integrally outside described foundation bolt 1 sponson and packing ring 5, nut 4, foundation bolt 1, nut 4 and packing ring 5 outer surface are all provided with oiliness anticorrosive paint layer, and be filled with a sealing between protective jacket 2 and foundation bolt component clay putty 3.
Described protective jacket 2 is made up of for threaded section 23 bottom straight section 21, middle part changeover portion 22 and top, protective jacket 2 is provided with the inner chamber of hollow, wherein the inner chamber size of straight section 21 adapts with the overall dimensions of packing ring 5 and nut 4, the inner chamber size of changeover portion 22 and foundation bolt 1 screw portion size adapt, and threaded section of 23 inner chamber set the external screw thread of female thread and foundation bolt 1 screw rod and are connected.
The height of described threaded section 23 is 5～8 times of foundation bolt pitch.
The one side thickness that described lute in putty 3 is filled is 1～1.5mm.
The material of described protective jacket 2 is plastics.
In this utility model, the oiliness anticorrosive paint layer of foundation bolt component adopts the method for brushing or spraying oiliness anticorrosive paint to arrange, the oiliness anticorrosive paint anticorrosive paint that in adopting, oily Hai Ke (Tianjin) anti-corrosion material company limited produces, this anticorrosive paint is by inertia grease, filler, corrosion inhibiter, half solidification oil pasty masses of preservative composition, its feature is non-sclerous in-50 DEG C～110 DEG C temperature ranges, do not solidify, oiliness protecting film can be formed on bolt surface, improve surface defect, and can with lute in putty 3 with the use of, there is the good compatibility.Lute in putty 3 is also that middle oil Hai Ke (Tianjin) anti-corrosion material company limited produces, the flexible glue pureed mixture being made up of inertia grease, filler, corrosion inhibiter, preservative, enhancing chopped fiber (or polyester foamed grain).Its composition is stable, non-sclerous, do not solidify, and has flexibility and the plasticity of excellence, inorganic acid resistance, alkali, salt corrosion, and there is good insulating properties.
