Keel structure and roof system

Abstract

The invention discloses a keel structure and a roof system. The keel structure comprises a main keel, an auxiliary keel fixedly mounted on the main keel through a first fastening component and a clamp for supporting the main keel, wherein the main keel comprises a horizontal plate and two vertical plates respectively arranged on the two sides of the horizontal plate in parallel, and a groove is jointly enclosed by the horizontal plate and the two vertical plates; the main keel further comprises two circuitous plates which respectively project and extend into the groove from the vertical plates and then are respectively circuitously bent towards the inner side of the groove, and the two circuitous plates are fixedly connected through a connecting plate; first back-hooking parts are arranged at the ends, far from the horizontal plate, of the vertical plates, and second back-hooking parts are arranged at the ends, far from the vertical plates, of the circuitous plates; a mounting groove is jointly enclosed by the vertical plates, the circuitous plates, the first back-hooking parts and the second back-hooking parts; and the clamp is mounted below the main keel. The keel structure is particularly suitable for outer decoration panels made of high-weight materials, such as support stainless steel plates.

Description

technical field [0001] The invention relates to the field of metal roofs, and more specifically relates to a keel structure and a roof system. Background technique [0002] In the construction industry, a metal roof system with a standing seam roof is often seen. It has the characteristics of large span and various shapes, and has an irreplaceable role in some occasions. The metal roofing system mainly includes standing seams, support seats, fixtures and exterior decorative panels. At present, the installation method of the outer decorative panel of this kind of metal roof is to directly connect the decorative panel to the fixture. However, when the outer decorative panel is a rusty steel plate, due to the heavy weight of a single panel, it is difficult to bear the material of the rusty steel plate when it is supported by the fixture. The load of the external decorative panel, the traditional roofing system can no longer meet the needs of the rusty steel plate material as t...
