Design and Force Analysis of A New Type of Prefabricated Ditch
Aiming at the vertical locking edge metal roofing system often adopts U-shaped compression strips and wind-resistant clip wind exposure measures,there are wind exposure efficiency is low,the appear-ance is not beautiful enough and other shortcomings,this paper through the roof panel in the T-type support under the laying of a layer of waterproofing roll-roofing material TPO,and based on the excellent airtight-ness,low elasticity and modulus of the characteristics of the existing vertical locking edge of the metal roof-ing to improve the wind exposure of the wind exposure design.The principle is to utilize the high airtightness and flexibility of TPO to preferentially consume the suction force generated by the roof wind;when TPO is in contact with the roof panel,both of them bear the wind load together,so that the wind uncovering perfor-mance of the whole system can be improved.Finally,through numerical calculation of its wind uncovering performance,compared with the traditional metal roofing system,its wind uncovering performance has been significantly improved.
