Method for enhancing wind uplift resistance and durability of metal roofing boards

Abstract

The invention discloses a method for enhancing wind uplift resistance and durability of metal roofing boards. The method is characterized in that a technician deeply researches a roofing system beforeconstruction to determine the position and size requirements of a T-shaped support of the metal roofing boards, and determine the size specification and model of a reinforcing component; the reinforcing component is divided into three parts of a main piece, an auxiliary piece and a bolt with a cap head, and the three parts are produced by a manufacturer, and are fastened and arranged after meshing and overlocking of the metal roofing boards are finished on site; and drilling is conducted through a high-speed steel drill, positioning is conducted through an auxiliary piece of a fastening fastener, the main piece is arranged and screwed down after drilling is completed, a second bolt is arranged according to the same method, and one reinforcing component can be arranged after two bolts arearranged. According to the method, due to the installation of the reinforcing component, the metal roofing boards and the T-shaped support are firmly connected, the wind uplift resistance of the roofing boards is greatly enhanced while the overall stress performance of the metal roofing boards is ensured, the maintenance cost of the roofing boards is greatly saved, the operation is simple and convenient, and the reinforcing effect is good.

Description

technical field [0001] The invention relates to the technical field of metal roof panels, in particular to a method for enhancing the wind resistance and durability of metal roof panels. Background technique [0002] Almost most modern public building roofs use metal roof panels. Compared with roof systems such as concrete roofs or tile surfaces, metal roof systems have a shorter installation period and better integrity. Factory processing and on-site cutting according to needs make construction more convenient. And the performance of metal roofing system including thermal insulation and sound absorption is unmatched by other roofing systems. The general metal roof panels are occluded and fixed by "T"-shaped aluminum alloy brackets, so that their waterproof performance and wind resistance performance are guaranteed to a large extent. However, during the long-term use of the metal roof panel fixed only by the "T" aluminum alloy bracket, under the repeated operation of temper...

AI Technical Summary

Problems solved by technology

However, during the long-term use of the metal roof panel fixed only by the "T" aluminum alloy bracket, under the repeated operation of temperature deformation stress and wind force, the occlusal part will inevitably be deformed to a certain extent, thereby reducing its wind resistance performance. The waterproof performance and durability will be affected to a certain extent; if there is water leakage or being overturned by the wind due to the large deformation of the roof panel in the later stage, the maintenance cost of the roof system will also be high
