Description
Technical field
The invention belongs to detecting instrument technical field, with Accurate Determining municipal administration bridge and civilian can be built more particularly to one kind
Build the detector of accommodation rail safety.
Background technique
Accommodation rail is a kind of important engineering protection class Accessory Members, is widely used in platform upper and stair side
Face ensures crowd's life security to prevent falling accident.Modern age individual building accommodation rail material is aggregate structure,
Modern architecture accommodation rail material is mostly cast iron or stainless steel, is individually wooden or plastic-aluminum.It is generallyd use between railing and handrail
Form is welded or is bolted to be attached.Accommodation rail bottom end generally using buried or bolt be anchored in platform or step it
It is interior, to play protective action.
But in practical projects, many factors may all influence the bearing capacity of accommodation rail.Firstly, no matter railing is helped
Hand getting is which kind of material, all there are endurance issues, accommodation rail is under moist or multigelation environmental condition, and railing root is all
It is possible that phenomena such as corroding, rotting.Secondly as railing belongs to Accessory Members, construction quality is usually ignored, railing bottom
Connecting portion is likely to Construction defect occur between portion and structural elements connecting portion and railing and handrail.In addition, railing
Handrail design selection is improper, insufficient rigidity, it is also possible to cause the deformation of accommodation rail top excessive.Above-mentioned factor all may cause
The forfeiture of its accommodation rail bearing capacity and safety assurance ability.
The degeneration or forfeiture of accommodation rail bearing capacity may directly result in the generation of falling accident, especially for the stream of people
The facilities such as the place of education such as biggish school, kindergarten or megastore and overline bridge are measured, such accident will lead to more
Serious consequence.Such as afternoon on July 10th, 2014, since balcony guardrail aging is broken, the 3 years old youngster in the Changsha International Residential Kai Tong one
Child's pendant is died.On July 18th, 2014, Wuhan steel continent garden district, when a Ms is faced upward by balcony iron railing, the railing fallen that becomes rusty is unexpected
It collapses, dies.When the June in 2018 of self-study at night break on the 20th, the new building Chinese ash school Zhong Jiao of foreign language and row in Zhengzhou
At three buildings vestibules of political affairs office building, because railing is broken suddenly, three boy students is caused to fall down from the building (Fig. 1).
Currently, country mainly has " civil buildings design general rule " for the building trade standard regulation of accommodation rail
GB50352-2005, " Code for design of dwelling houses " GB50096-1999, " middle and primary schools' design specification " GB50099-2011, " child
