Construction method of metal tile and metal eave-rafter built-up roof

Abstract

The invention discloses a construction method of a metal tile and metal eave-rafter built-up roof. The construction method comprises the following steps that S1, built-in fittings (9) are amounted ina structural main body (10); S2, a support skeleton (7) is assembled on the structural main body through the built-in fittings; S3, a profiled steel plate (6) is laid; S4, waterproof plates (5) are laid; S5, an eave-rafter metal plate (8) is mounted; S6, purlins (4) are laid; S7, rafters (3) are laid; S8, metal tiles (2) are laid; S9, a metal pressing beam (1) is mounted at the ridge, and the upper end of one waterproof plate is extended into the metal pressing beam and is sealed; and S10, drip tile pieces (24) and eave tile pieces (23) are mounted on the metal tiles. According to the construction method, the connection air tightness and the water tightness of the metal tile and metal eave-rafter built-up roof are ensured, so that the roof structure does not leak and does not deform, and then the roof structure has good wind resistance and waterproof performance.

Description

Technical field [0001] The invention relates to a construction method of a roof structure, in particular to a construction method of a combined roof of metal tiles and metal eaves rafters. Background technique [0002] Currently, archaized buildings at home and abroad are mostly constructed in the form of combined roofs. The common roof form combining metal tiles and metal eave rafters is a combination of an independent upper metal tile roof system and an independent lower metal eave rafter system. This combined roof has the characteristics of good appearance. However, the following situations are prone to occur during the application process: [0003] (1) For roofs with a larger area, the prior art roofing system combining metal tiles and metal eaves rafters may easily cause safety hazards of instability of the roof support framework due to its large weight. [0004] (2) There is a gap between the waterproof board of the upper metal tile roof system and the waterproof board of the...

AI Technical Summary

Problems solved by technology

[0003] (1) For larger roofs, the roof system combined with metal tiles and metal eaves and rafters in the prior art will easily cause safety hazards of roof support frame instability due to its own weight

[0004] (2) There is a gap between the waterproof board of the upper metal tile roof system and the waterproof board of the lower metal eaves rafter system in the prior art. In coastal typhoon areas with large wind loads, the waterproof board is easily deformed or waterproofed under the action of negative wind pressure The plate and the adapter piece fall off, which is easy to cause separation and water leakage

Once separation and water leakage occur, maintenance is more difficult and costly, and safety hazards cannot be effectively eliminated after maintenance

[0005] In the existing construction system, there is not a complete set of standardized processes for reference in the combined roof construction of metal tiles and metal aluminum rafters

Especially in coastal typhoon areas with large wind loads, poor construction quality can easily cause roof separation and water leakage. Metal composite roofs are different from concrete roofs, and leakage points cannot be found, which greatly reduces the safety and security of buildings. Residential experience
