Description
Technical field
Corrugated sheet is gone along with sb. to guard him in a kind of integrated building shielding that the present invention relates to electromagnetic shielding and building field.Specifically high-performance, a multi-functional corrugated sheet of going along with sb. to guard him for architectural shielding, this integrated building shielding is gone along with sb. to guard him corrugated sheet and is not only applicable to power test hall, is also applicable to shield the place of going along with sb. to guard him requirement, for example Forces Command Post, anechoic chamber, etc.
Background technology
In recent years, for the demand of architectural shielding, particularly growing to the demand in power test shielding hall, market prospects are wide especially both at home and abroad.
The patent that announce applicant's 7 days July in 2010, " for the corrugated sheet of architectural shielding " (patent No. ZL2009.1.0033117.9), after coming into the market, demonstrate powerful vitality, short more than 3 years in the time, having substituted traditional framed (piece) formula shielding construction completely, is a subversive revolution of shielding industry, has created more value and abundant return to society to client simultaneously.
Existing space enclosing structure-individual layer or composite laminboard, only only have safeguard function, do not have function of shielding.
Existing containment system exists surface and sees that head of screw, multiple tracks transverse joint, vertical overlap joint, sealing are poor, receives limit and angle of cut processing and the defect, particularly leakage problem such as be not good at, and has greatly affected application life.
For the corrugated sheet of architectural shielding, still can not meet the requirement of going along with sb. to guard him at present.Combine with shielding corrugated sheet if will go along with sb. to guard him corrugated sheet, can not embody advanced and creative.
Client is expecting to occur a kind of more novel shielding product, unites two into one going along with sb. to guard him with shielding, has multi-functionally, greatly shortens the construction period, is that client creates higher technology and economic worth, saves Installed capital cost also to country simultaneously.
The present invention once designs just can reach shielding and Support Function.Traditional design, first carries out the design of steel knot containment system, secondly carries out double optimization design by unit in charge of construction, finally carries out optimum design for the shielding protection by shielding manufacturer.Exist many problems, often an engineering construction is over, and Change In Design has not also had.Owner is entangled with very much, has much shortcoming and helpless, produces many problem engineerings.
It is very significant that the integrated architectural shielding of one of the present invention is gone along with sb. to guard him corrugated sheet, is another subversiveness revolution of shielding industry, has really realized shielding and architecture-integral, makes shielding easier, more economical, more scientific.Present low-carbon (LC), green, the multi-functional completely new product of energy-saving and environmental protection to society!
