Analyze the back to the roofing after being destroyed by strong wind and find, weak link is in gutter, ridge, skylight, cornice zone, and the free end of roofing metal sheet is destroyed by strong wind the most easily.Because the draining and the connection performance of die mould metal roofing board, the termination of die mould metal roofing board need outer a part of length of choosing, the length that the free end of gutter is chosen is outward confirmed after need calculating according to the coefficient of thermal expansion and contraction of metal sheet, usually at 200～300mm.Choosing length outward can not be too short, otherwise after die mould roofing metal sheet expanded with heat and contract with cold, rainwater can't enter gutter.Ridge, skylight, cornice also need certain outer length of choosing because of structure requires the plate end from the bearing of interlock.Choose part outward under big wind action, can receive power upwards and downward power reciprocating, free end is peeled off from the bearing of interlock, thereby whole roofing is formed destruction.On the other hand when the roofing free end is cut sth. askew, the actual width (slope length) that uses is will be much larger than design load (roof panel horizontal width) time, and safety factor reduces greatly.Lift badly in case there is the fraction roof panel to be torn, will cause that the chain reaction tearing port enlarges rapidly the safety that jeopardizes whole roofing by strong wind.
Therefore improving the wind loading rating of whole roofing, the roof board wind weak link is strengthened handling, particularly die mould metal sheet gutter, ridge, skylight, cornice zone free end are strengthened handling, is scientific and technical personnel's in the industry effort target.
Summary of the invention
The objective of the invention is that the roof panel free end is constructed wind resistance and strengthen, particularly die mould metal sheet gutter, ridge, skylight, cornice zone free end wind resistance are strengthened handling, a kind of die mould metal roofing board free end end wind resistance connector is provided.
For realizing above-mentioned purpose; The technical scheme that adopts is: a kind of die mould metal roofing board free end end wind resistance connector; Comprise metal roofing board and roofing skeleton; It is characterized in that: the wind resistance accessory is L shaped, and the upper end horizontal plane is fixedly connected with metal roofing board, and vertical edges is equipped with and can supplies the wind resistance shoulder pole to run through the square hole that passes through; The wind resistance shoulder pole is zigzag, and an end end is equipped with the slip-off preventing flanging, and the other end runs through through the square hole on the said wind resistance accessory and is connected with said roofing skeletal fixation.
The width of said slip-off preventing flanging is greater than the width of said square hole, inserts landing from square hole again behind the square hole to prevent the wind resistance shoulder pole.
The present invention has following advantage: the wind resistance accessory can elongatedly be provided with; Wind resistance shoulder pole quantity has a plurality of; In the middle of each roof panel free end, all need be provided with one; So a wind resistance accessory can be used with a plurality of wind resistance shoulder poles, and the roof panel free end is linked to be an integral body, makes it to become whole wind resistance from the monolithic wind resistance; After the wind resistance shoulder pole inserts simultaneously, can control the whole deflection up and down of roof panel, thereby improve wind loading rating greatly.Owing to adopt the wind resistance shoulder pole to run through wind resistance accessory square hole connected mode, the wind resistance accessory can be on the wind resistance shoulder pole before and after slippage, do not influence freely stretch (the expanding with heat and contract with cold) of die mould metal roofing board.The present invention is simple and reasonable, easy for installation, connection is very firm, and overall security is good.
