Description

Technical Field

[0001] The invention relates to the technical field of building steel structures and metal roofs, and in particular to a high-performance, large-span integrated metal roof system. Background Art

[0002] In the construction process of modern large-scale public buildings (such as stadiums, airport terminals, exhibition centers, etc.), large-span steel structures and metal roofing systems are indispensable key components. The two are not only interdependent in structure, but also form a pair of closely connected "twin brothers" in function. However, since they belong to different sub-industries, their professional design and professional construction lead to the widespread disconnection between design and construction. Therefore, in actual operation, the problem of separation between design and construction is often faced, which brings considerable challenges to the project's construction period, quality and cost control. As a result, the existing metal roofing systems usually have a large number of components, low installation efficiency, and high overall cost.

[0003] In view of this, this application is made. Summary of the invention

[0004] The present invention provides a high-performance large-span integrated metal roof system, which combines the respective characteristics of large-span steel structure and metal roof to solve some problems existing in the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a high-performance large-span integrated metal roof system, including a steel structure beam, a roof main purlin and a roof secondary purlin, a column is connected between the steel structure beam and the roof main purlin, a roof bottom plate is arranged on the steel structure beam, a reinforcing cover plate is arranged on the roof bottom plate, a plurality of roof panel supports are arranged on the roof secondary purlin, and a metal roof panel is arranged on the roof panel supports.

[0006] Furthermore, a leveling steel plate is laid on the roof bottom plate.

[0007] Furthermore, a vapor barrier membrane, thermal insulation rock wool and a flexible waterproof membrane are sequentially laid on the leveling steel plate.

[0008] Furthermore, the flexible waterproof coiled material is turned up at the column and connected to the column by a stainless steel clamp.

[0009] Furthermore, a groove-shaped connecting piece is provided on the steel structure beam, and the roof bottom plate is fixed to the groove-shaped connecting piece.

[0010] Furthermore, the roof base plate is a high-performance base plate, which adopts a large-wave high-pressure steel plate with a wave height greater than 70 mm, and sound-absorbing cotton is arranged between the waves.

[0011] Furthermore, the steel structure beams are main structure members or purlin members above the main structure, and the beam spacing of the steel structure beams is controlled between 3 and 6 meters.

[0012] Furthermore, a bottom plate reinforcement node is provided on the steel structure beam, including a bottom plate support. The reinforcement cover plate is arranged at the bottom plate support and adopts the same plate type as the roof bottom plate. Adhesive is applied between the reinforcement cover plate and the roof bottom plate for locally reinforcing the support node.

[0013] Furthermore, the reinforced 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 specifications.

[0014] Furthermore, the reinforcing cover plate adopts the same plate type as the roof base plate, adhesive is applied between the reinforcing cover plate and the roof base plate, and is arranged at the base plate support to locally strengthen the support node.

[0015] Furthermore, the secondary roof purlins are connected to the main roof purlins through bolts and connecting plates; the main roof purlins are welded to the columns through roof purlin brackets, and the tops of the columns are provided with closed steel plates for leveling.

[0016] In summary, the present invention adopts a high-performance roof bottom plate, which greatly increases the span of the roof bottom plate, controls the spacing of the steel structure beams, and completely eliminates the roof bottom plate purlins, thereby greatly reducing the number of roof components, improving the installation efficiency of the roof, and reducing the cost of the roof system. Compared with the prior art, the present invention has the following beneficial effects: (1) High-performance large-span base plate: By adopting high-performance roof base plates and locally strengthening the support nodes, the span capacity of the roof base plate is greatly improved, and the plate span capacity can reach about 3 to 6 meters.

[0017] (2) Integration of steel structure and metal roof: By adopting high-performance roof base plates, the plate span capacity can reach about 3 to 6 meters, which can greatly reduce the number of purlins. By reasonably controlling the spacing between steel structure beams, purlins can be eliminated, thereby greatly reducing the amount of steel used in the roof base plate purlins.

[0018] (3) Providing an installation platform: By adopting a high-performance roof base plate, roof-related operations can be performed directly on the roof base plate during the installation process, eliminating the need to set up temporary installation measures and improving the safety of the installation process.

[0019] (4) Shorten the installation cycle: By reducing the number of roof base purlins and using high-performance roof base as the installation platform for subsequent roofs, the roof installation efficiency is greatly improved and the installation cycle is effectively shortened.

[0020] (5) Reduce the cost of the roof system: The cost of the roof system can be effectively reduced by reducing the amount of steel used in roof purlins and shortening the installation period. BRIEF DESCRIPTION OF THE DRAWINGS
