Problems solved by technology
The nail-type lap joint method has concentrated stress at the nail joint, and the strength and rigidity are not enough to resist harsh weather conditions; in addition, the screws and the roof panels are made of different materials and they are in direct contact. Long-term exposure outdoors is likely to cause electric shock between the two. The roof panels are corroded by chemical reactions, and the watertight and airtight performance of the nailed lap joint is not ideal
[0003] Therefore, there is a need for a new overlapping method of bolt assemblies with stronger wind and waterproof functions to overcome the disadvantages of poor durability, easy to corrode, reduce the wind resistance of the roof and easy to leak in the prior art

The invention provides a horizontal lapping method for a metal roof panel system, which comprises the steps as follows: a water-proof packing rubber strip is laid at the end part of a downhill roof panel, and a center line is aligned to a plurality of precast holes; a reinforced back panel is provided, a plurality of pressure riveting bolts are riveted and fixed on the reinforced back panel in the width direction, and the pressure riveting bolts penetrate through the precast holes and the water-proof packing rubber strip on the downhill roof panel from bottom to top; the pressure riveting bolts penetrate through the precast holes formed on an uphill roof panel from top to bottom; a hold-down strip is provided, a plurality of mounting holes are formed in the hold-down strip in the width direction, and the pressure riveting bolts penetrate through the hold-down strip through the mounting holes from top to bottom and are jointed with the surface of the uphill roof panel; in addition, stop nuts are respectively installed on the pressure riveting bolts, and the uphill roof panel and the downhill roof panel are connected in a tightly overlapping manner. The horizontal lapping method has the characteristics of attractive appearance, durability, seepage resistance, wind load-bearing capacity and the like, is better than the traditional lapping manner on the aspects of saving installation cost, improving field construction efficiency and the like, and shows the unique superiority.
Description
technical field [0001] The invention relates to the technical field of overlapping of metal roof panel systems, in particular, the invention relates to a method for horizontal overlapping of metal roof panel systems. Background technique [0002] At present, the connection method of the horizontal overlap of the metal roof panel system commonly used in construction is the method of direct nailing connection of double-layer panels. The nail-type lap joint method has concentrated stress at the nail joint, and the strength and rigidity are not enough to resist harsh weather conditions; in addition, the screws and the roof panels are made of different materials and they are in direct contact. Long-term exposure outdoors is likely to cause electric shock between the two. The chemical reaction will corrode the roof panel, and the watertight and airtight performance of the nailed lap joint is not ideal. [0003] Therefore, there is a need for a new overlapping method of bolt assem...
