Preferably, two metal roof boarding of anti-wind combination support both sides that slide between be equipped with interlock limit, the interlock groove of mutually supporting, the interlock groove for falling the U type, the interlock limit locate in the interlock groove, interlock limit and interlock groove between be equipped with continuous welding seam. The inverted U-shaped occlusion groove is positioned at the upper end of the joint of the two metal roof boards, the occlusion edge is inserted into the occlusion groove from the bottom, and rainwater and snow water can be well prevented from leaking into a room from the joint of the two metal roof boards after the structure is continuously welded and fixed.

Preferably, the linear sliding direction of the bottom end of the sliding seat on the base is the length direction of the metal roof panel. The length of the metal roof board far exceeds the width, so the influence of expansion with heat and contraction with cold on the length direction is the largest, and the direction of the linear sliding of the bottom end of the sliding seat on the base is matched with the length direction of the metal roof board.

Preferably, the base is an aluminum alloy base. The base of the scheme can also be an equivalent stainless steel base.
