Metal roof system

Abstract

The invention relates to metal roof system structural modification and provides a metal roof system. The metal roof system comprises color steel roof panels disposed on purlines. A gutter is correspondingly disposed at the end of each color steel roof panel. The side of each color steel roof panel is connected with a gable closing edge of a wall face outer board. The metal roof system is characterized in that the color steel roof panels are mutually connected through lap joint fasteners. Each lap joint fastener comprises a support plate disposed below a color steel roof panel lap joint part and a pressing strip disposed above the color steel roof panel lap joint part, the support plate is provided with riveting screws, the pressing strip is fixed with the riveting screws penetrating the color steel roof panel lap joint part, and an arc-shaped water hole is formed in the pressing strip. The metal roof system is good in wind pressure resistance and waterproofing and reasonable in connecting structure.

Description

technical field [0001] The invention relates to an improvement of a metal roof system structure. Background technique [0002] At present, the existing metal roofing system has many problems due to its unreasonable structure: 1. The overlapping of two color steel roof panels is unreasonable, and it is difficult to guarantee the wind pressure resistance and waterproof performance. [0003] The traditional lapping of color steel roof panels is to add a lining plate at the bottom, and use self-tapping nails to directly drill through the color steel roof panel to fasten the color steel roof panel with the lining plate. This connection method, because the color steel roof panel does not have pre-punched holes and beading, and there are many human factors when nailing, it is difficult to guarantee the overall resistance to wind pressure and waterproof performance of the color steel roof.

AI Technical Summary

Problems solved by technology

[0002] At present, the existing metal roof system has many problems due to its unreasonable structure: 1. The overlapping of two color steel roof panels is unreasonable, and it is difficult to guarantee the wind pressure resistance and waterproof performance

This connection method, because the color steel roof panel does not have pre-punched holes and beading, and there are many human factors when nailing, it is difficult to guarantee the overall resistance to wind pressure and waterproof performance of the color steel roof.

[0004] 2. The structure of the gutter pull belt is unreasonable: the traditional gutter pull belt is a galvanized sheet bent U-shaped groove buckled on the wave crest of the roof panel, and connected to the gutter with self-tapping screws. The disadvantages are: the appearance is not beautiful and cannot be adjusted The angle between the roof panel and the gutter, the design of the U-shaped groove of the gutter belt and the connection between the roof panel have hidden dangers of water seepage

[0005] 3. The plug structure at the eaves of the existing color steel roof is unreasonable: the crest of the color steel roof forms a certain space at the eaves, in order to ensure the air and water tightness of the color steel roof and prevent birds from To build a nest in the space, it is necessary to set up a plug in the space; the traditional color steel plate roof eaves use foam (PE) plugs, and use double-sided tape to stick the foam plugs to the bottom of the color steel plate peaks, which is only a temporary perfunctory project Acceptance, can not achieve the proper function; poor sealing performance, and easy to fall off

[0006] 4. The connection structure between the metal roof panel and the color steel plate gable is unreasonable: at present, the connection method between the metal roof panel and the color steel gable is: the metal roof is directly connected to the color steel gable by nailing; The deformation caused by expansion and contraction is usually set as a sliding structure. However, the method of directly connecting the metal roof and the gable makes the metal roof at the connection with the gable lose the ability to slide; this will have adverse effects on the entire roof system. influences

[0007] 5. The connection structure between the color steel roof panel and the purlin is unreasonable: the color steel roof panel needs to be fixed on the purlin through the fixing seat. Due to the influence of temperature changes, the color steel roof panel will expand with heat and contract with cold; in addition, the roof purlin There is also the problem of unevenness on the upper surface

The existing color steel plate fixing seat usually only has the sliding function of the slidable color steel roof panel, so as to absorb the deformation caused by thermal expansion and contraction

However, it fails to solve the problem of unevenness on the upper surface of the roof purlins. At present, this problem can only be solved by the incomplete contact between the fixing seat and the roof color steel plate

[0008] 6. The structure of the fan base installed on the color steel roof panel is unreasonable: the surface of the color steel roof panel has crests. Since the bottom surface of the existing fan base is flat, it is necessary to cut off the crest of the color steel roof panel when installing the fan base. , which not only destroys the structure of the roof system, but also has a great impact on the waterproof performance of the roof system
