Description

Technical Field

[0001] The present invention relates to a metal roof structure, and particularly to a wind-resistant and stable metal roof structure at the ridge. Background Art

[0002] Due to the use of high-quality metal plates as materials, metal roofs have the characteristics of energy conservation, environmental protection, fast installation, durability, and fashion, and are favored by the majority of property owners. As disclosed in the patent with the publication number CN113107142B, the metal roof ridge is an important structure during the installation of the metal roof and is an important node related to the connection of the metal roof and the overall waterproof effect. The rigid connection setting of the metal roof ridge is likely to cause the risk of damage to the metal roof panel and the aluminum alloy support, and is easily damaged by strong winds. It is not conducive to the construction period and cost control. Summary of the Invention

[0003] The purpose of the present invention is to provide a wind-resistant and stable metal roof structure at the ridge to solve the above technical problems.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions: A wind-resistant and stable metal roof structure at the ridge, including a main steel structure, secondary purlins, wire mesh, thermal insulation cotton, aluminum foil, standing seam steel roof panels, locking joints, folding corners, outer sealing plate assemblies, supports, and flashing plates. The main steel structure is distributed on the metal roof, the secondary purlins are installed at the top of the main steel structure, the wire mesh is laid on the secondary purlins, the thermal insulation cotton is laid on the wire mesh, the aluminum foil is laid on the thermal insulation cotton, the standing seam steel roof panels are installed at the top of the aluminum foil through the secondary purlins, and the standing seam steel roof panels are connected through the locking joints. The folding corners are folded upwards at the inner ends of the standing seam steel roof panels. The outer sealing plate assemblies are installed near the ridge of the standing seam steel roof panels, and the peripheries of the outer sealing plate assemblies are caulked and sealed. The supports are installed on the outer sealing plate assemblies, and the flashing plates are installed at the ridge through the outer sealing plate assemblies.

[0005] Based on the above technical solutions, the support includes a bracket, a connection structure, galvanized bolts, galvanized gable fittings, hexagon machine screws, stainless steel rivets, and self-tapping and self-rotating screws. The bracket is installed inside the locking joint, the connection structure is connected to the locking joint, the galvanized bolts connect the connection structure and the bracket, the galvanized gable fittings are arranged at the top of the locking joint, the hexagon machine screws fix the galvanized gable fittings, the stainless steel rivets fix the outer sealing plate assembly to the galvanized gable fittings, and the self-tapping and self-rotating screws fix the bracket to the secondary purlins.

[0006] Based on the above technical solutions, the self-tapping and self-rotating screws are coated with weather-resistant sealant.

[0007] Compared with the prior art, the present invention has the following advantages: The standing-seam steel roof panel of the present invention is fixedly connected by abutting against the support. The support fixed to the secondary purlin is rigidly connected to the outer cladding plate assembly, avoiding damage to the metal roof caused by rigid connection during construction, and buffering the wind to a certain extent in the face of strong wind weather, increasing the wind resistance, reducing the cost waste caused by traditional construction processes, shortening the construction period, and ensuring the construction quality.

DETAILED DESCRIPTION OF THE INVENTION

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] As Figures 1 to 4 shown, a wind-resistant and stable metal roof structure at the ridge includes a main body steel structure 1, secondary purlins 2, wire mesh 3, thermal insulation cotton 4, aluminum foil 5, standing-seam steel roof panels 6, seam connections 7, folding angles 8, outer cladding plate assemblies 9, supports 10, flashings 11. The main body steel structure 1 is distributed on the metal roof. The secondary purlins 2 are installed at the top of the main body steel structure 1. The wire mesh 3 is laid on the secondary purlins 2. The thermal insulation cotton 4 is laid on the wire mesh 3. The aluminum foil 5 is laid on the thermal insulation cotton 4. The standing-seam steel roof panels 6 are installed on the top of the aluminum foil 5 through the secondary purlins 2, and the standing-seam steel roof panels 6 are connected through the seam connections 7. The folding angles 8 are folded upwards at the inner ends of the standing-seam steel roof panels 6. The outer cladding plate assemblies 9 are installed at the near-ridge positions of the standing-seam steel roof panels 6, and sealant is applied around the outer cladding plate assemblies 9. The supports 10 are installed on the outer cladding plate assemblies 9. The flashings 11 are installed at the ridge through the outer cladding plate assemblies 9.

[0015] The support 10 includes a bracket 12, a connection structure 13, a galvanized bolt 14, a galvanized gable fitting 15, a hexagonal machine screw 16, a stainless steel blind rivet 17, and a self-tapping and self-drilling screw 18. The bracket 12 is installed inside the seamed joint 7, the connection structure 13 is connected to the seamed joint 7, the galvanized bolt 14 connects the connection structure 13 and the bracket 12, the galvanized gable fitting 15 is disposed on the top of the seamed joint 7, the hexagonal machine screw 16 fixes the galvanized gable fitting 15, the stainless steel blind rivet 17 fixes the outer cladding panel assembly 9 to the galvanized gable fitting 15, and the self-tapping and self-drilling screw 18 fixes the bracket 12 to the secondary purlin 2.
