Description
Technical field
The invention belongs to electromagnetic shielding square cabin field, especially relate to the manufacture method of the electromagnetic shielding square cabin that relies on exterior skin shielding.
Background technology
Domestic market increases gradually for the demand of shielding shelter, and capability of electromagnetic shielding is all to have very important effect for civilian or Military Shelter.
Shielding shelter mainly contains two kinds of modes: inside panel shielding, exterior skin shielding.The mode that most shielding shelter adopts is inside panel shielding, and in adopting between inside panel, aluminum corner brace connects, and forms one six shieldings.But rack, the equipment of shelter inside are more, need installation firmly, reliably, just rack, equipment etc. must be spirally connected or rivet with the backing plate of large intralamellar part, so the hole count on inside panel is also many, be the latency that causes leakage field.
More due to shelter appearance face, gap, the rivet hole in especially outer aluminum corner brace, causes shield effectiveness to be difficult to reach desirable index.Outer aluminum corner brace adopts riveting method to be connected with large plate, will hole, to guarantee aluminum corner brace installation strength and surface finish in aluminum corner brace.In order to reach shield effectiveness, pitch-row will guarantee that the linear gap length of aluminum corner brace is in certain scope, and the linear dimension in General Requirements gap is less than λ/10～λ/100.And also will carry out waterproofing work between aluminum corner brace and large plate exterior skin outside, aluminum corner brace inner surface applies fluid sealant outside, for the metal continuity of aluminum corner brace and exterior skin, there is larger impact.Therefore the hole in aluminum corner brace, seam have very significantly impact to the capability of electromagnetic shielding of shelter.

The manufacture method of described electromagnetic shielding square cabin is: adopt gas shielded welding mode along sowing weldering the outer aluminum corner brace of shelter and exterior skin, described gas is pure argon; After outer aluminum corner brace and interior aluminum corner brace installation, conducting resinl is injected from the hole for injecting glue in outer aluminum corner brace, fill up the gap between whole groove and outer aluminum corner brace and exterior skin; At shelter San Kuai great plate, lap-joint is welded with aluminium corner fittings, and lap gap full weld, to guarantee the shielding properties of San Kuai great plate lap-joint.
In described outer aluminum corner brace welding process, to keep the contact surface of outer aluminum corner brace and exterior skin continuous, smooth, with compact heap, compress respectively outer aluminum corner brace and exterior skin, radiating block is installed in compact heap end simultaneously, is guaranteed that the deflection of solder side, in controlled range, does not affect appearance quality.
Electromagnetic shielding square cabin of the present invention relies on outer surface shield, and the metal continuity by between large plate exterior skin, reaches effectiveness.The invention solves shelter appearance face, gap is more and cannot reach the technological difficulties of shielding requirements, can effectively improve the electromagnetic shielding index of shelter integral body.Also solved that the outer aluminum corner brace of shelter is rainproof, seepy question simultaneously, avoided in aluminum corner brace, holing outside, and aluminum corner brace internal high pressure has injected conducting resinl outside, both played and connected outer aluminum corner brace and exterior skin and conduct electricity successional effect, played again the effect of rainwater-proof.Because adopting, outer aluminum corner brace and outer illiteracy be welded to connect, welding is shunk exterior skin is formed to pretightning force, can reduce the bulge of shelter exterior skin, unsticking phenomenon to playing effective prevention effect because external temperature environment changes the skin morph causing, improve shelter quality, life-span.
