Solution of the present utility model is: a kind of outdoor cabinet electrolytic zinc-coated steel sheet anti-corrosion structure, it comprises two the electrolytic zinc-coated steel sheet structural members (1) be welded to connect, side coating protection layer (3) being arranged on two electrolytic zinc-coated steel sheet structural member (1) outer surfaces, two electrolytic zinc-coated steel sheet structural members (1) are all bent to form respective vertical kink (4) at the place of being welded to connect towards outdoor cabinet internal vertical, and vertical kink (4) is housed in outdoor cabinet inside and extends into the length difference of outdoor cabinet inside; The place of being welded to connect of two electrolytic zinc-coated steel sheet structural members (1) is provided with some pads (2); Coating protection layer (3) covers the joining place of two electrolytic zinc-coated steel sheet structural members (1).
As the further improvement of such scheme, the vertical kink (4) extending into the length of outdoor cabinet inside shorter is provided with some pads (2).
Further, some pads (2) are evenly distributed on corresponding vertical kink (4).
Preferably, some pads (2) are evenly distributed on corresponding vertical kink (4) along the bearing of trend perpendicular to vertical kink (4).
As the further improvement of such scheme, extend into the vertical kink (4) that the length of outdoor cabinet inside is shorter, its end face is also provided with some pads (2).
Further, on bearing of trend perpendicular to vertical kink (4), the pad (2) of outer most edge is less than 20mm apart from the distance of corresponding outer rim.
Preferably, the length extending into the shorter vertical kink (4) of the length of outdoor cabinet inside is less than 20mm.
As the further improvement of such scheme, the Welding Structure that two electrolytic zinc-coated steel sheet structural members (1) are spliced for structural member.
Preferably, two electrolytic zinc-coated steel sheet structural members (1) are section welding structure or full weld structure or plug welding structure.
As the further improvement of such scheme, the thickness of coating protection layer (3) is 80 ~ 100 μm.
The beneficial effects of the utility model: namely achieve the electrolytic zinc-coated steel sheet that outdoor rack outer surface is complete coating, welding and sheet material cross section are arranged on the inside of rack without coating position, improve the corrosion fatigue life of electrolytic zinc-coated steel sheet outdoor cabinet; In addition can avoid rack outer surface after the application such as plastic-blasting because transport, install, outer surface corrosion that defect that local coatings in use procedure comes off causes, this structure has given full play to the decay resistance of electrolytic zinc-coated steel sheet anodic protection coating; In addition, this anti-corrosion structure can simply, conveniently realize, and can be widely used in sheet material panel beating.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See also Fig. 1, Fig. 2 and Fig. 3, the outdoor cabinet electrolytic zinc-coated steel sheet anti-corrosion structure of present embodiment comprises two the electrolytic zinc-coated steel sheet structural members 1 be welded to connect, the side coating protection layer 3 being arranged on two electrolytic zinc-coated steel sheet structural member 1 outer surfaces.
Two electrolytic zinc-coated steel sheet structural members 1 are all bent to form respective vertical kink 4 at the place of being welded to connect towards outdoor cabinet internal vertical, and vertical kink 4 is housed in outdoor cabinet inside and extends into the length difference of outdoor cabinet inside.The place of being welded to connect of two electrolytic zinc-coated steel sheet structural members 1 is provided with some pads 2, and in the present embodiment, the vertical kink 4 extending into the length of outdoor cabinet inside shorter is provided with 6 pads 2.The length extending into the shorter vertical kink 4 of the length of outdoor cabinet inside is less than 20mm.Pad 2 is positioned at stitching portion within distance structure part bending width 20mm or sheet material cecum cross section, and then ensures the intensity that is welded to connect.As shown in Figures 1 and 3, the pad 2 on most limit is less than 20mm apart from end face length L; Pad 2 is positioned at the stitching portion within distance structure part bending width 20mm or is positioned at bending width h and is less than on the cross section of structural member sheet material cecum of 20mm, thus ensures the intensity that rack is welded to connect.In addition, extend into the vertical kink 4 that the length of outdoor cabinet inside is shorter, its end face also can be provided with some pads 2.
Outdoor cabinet electrolytic zinc-coated steel sheet anti-corrosion structure by two electrolytic zinc-coated steel sheet structural member 1 junctions by welding in the inner side of cabinet structure part after vertical bending, do not have the position of anodic protection coating to be installed in the inside of rack in pad 2, welded section and sheet material cecum cross section etc., then coating protection layer 3 is arranged respectively to this structure surfaces externally and internally; Outdoor cabinet electrolytic zinc-coated steel sheet anti-corrosion structure using the outer surface of the electrolytic zinc-coated steel sheet face of intact coating as outdoor cabinet, decay resistance weak without plating defect position as inner surface.Ensure that the overall high-corrosion resistance of electrolytic zinc-coated steel sheet outdoor cabinet outer surface.
On bearing of trend perpendicular to vertical kink 4, the pad 2 of outer most edge is less than 20mm apart from the distance of corresponding outer rim.6 pads 2 are preferably evenly distributed on corresponding vertical kink 4, can be evenly distributed on corresponding vertical kink 4 along the bearing of trend perpendicular to vertical kink 4, carry out and accomplish that the bearing of trend along perpendicular to vertical kink 4 is in one line, of course along the bearing of trend perpendicular to vertical kink 4, dislocation arranges and is also fine.
Two electrolytic zinc-coated steel sheet structural members 1 can be the Welding Structure of structural member splicing, as section welding structure or full weld structure or plug welding structure.Coating protection layer 3 covers the joining place of two electrolytic zinc-coated steel sheet structural members 1.The thickness of coating protection layer 3 is 80 ~ 100 μm.Coating protection layer 3 can be sprayed plastic coat, complete coating anticorrosive structure surfaces externally and internally, the outside weld gap of interstitital texture part welding.Therefore coating protection layer 3 can be plastic-blasting process, outdoor powder sprayed plastic coat thickness is 80 ~ 100 μm.Respectively plastic-blasting application is carried out to anti-corrosion structure surfaces externally and internally, the surfaces externally and internally of complete covered structure part, the outside weld gap of interstitital texture part welding, prevent weld gap place condensation from entering inside gap and corrosion occurs.
In sum, the utility model is for improving the corrosion-resistant useful life of outdoor electrolytic zinc-coated steel sheet rack.The pad of electrolytic zinc-coated steel sheet is installed in the inside of cabinet structure part by the utility model, and carries out welding to electrolytic zinc-coated steel sheet structural member, then carries out plastic-blasting application to the surfaces externally and internally of rack.The utility model both can meet welded intensity, the electrolytic zinc-coated steel sheet coating structure that rack outer surface is complete can be realized again, good protective is still had without coating open-bottom bubble defect at scuffing, the small size caused that collides with, reach the high-corrosion resistance of electrolytic zinc-coated steel sheet rack, and then ensure that the corrosion-resistant useful life of outdoor cabinet.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
