Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building steel structure and metal roof, especially relates to a high performance large span integrated metal roof system. BACKGROUND

[0002] In the construction process of modern large public buildings (such as stadiums, airport terminals, exhibition centers, etc.), large-span steel structure and metal roof system are indispensable key components. Both are not only dependent on each other in structure, but also form a pair of "twin brothers" closely linked in function. However, due to their belonging to different sub-sectors, the design and construction of different specialities lead to the common situation of disconnection between design and construction. Therefore, in actual operation, we often face the problem of separation of design and construction, which brings great challenges to the project schedule, quality and cost control. Therefore, the existing metal roof system usually has the problems of large number of components, low installation efficiency and high overall cost.

[0003] In view of this, the present application is made. UTILITY MODEL CONTENT

[0012] Further, a bottom plate reinforcing node is arranged on the steel structure beam, and the reinforcing cover plate is arranged at the bottom plate support and adopts the same plate type as the roof bottom plate.

[0013] Further, the reinforcing cover plate protrudes from the bottom plate support in the width direction, and the protruding width is determined according to the actual specific plate type specification.

[0014] Further, the reinforcing cover plate adopts the same plate type as the roof bottom plate, and an adhesive is applied between the reinforcing cover plate and the roof bottom plate, and the reinforcing cover plate is arranged at the bottom plate support to locally reinforce the support node.
