Combined roofing system of metal tiles and metal eave rafters

Abstract

The invention discloses a combined roofing system of metal tiles and metal eave rafters. The combined roofing system comprises a metal pressing beam (1), the metal tiles (2), rafters (3), purlines (4), a waterproof board (5), a profiled steel plate (6), a supporting framework (7) and an eave rafter metal plate (8) which are arranged on a main body structure (10); embedded parts (9) are embedded inthe main body structure, the supporting framework is installed on the main body structure through the embedded parts, an upper inclined framework (72) is equipped with an adapter (74), the profiled steel plate is installed on the upper inclined framework through the adapter, the waterproof plate is installed on the profiled steel plate and a lower inclined framework; the purlines are connected with the adapter, the rafters are installed on the purlines, the metal tiles are installed on the rafters, and the metal pressing beam is installed on the top part of the supporting framework and connected with the metal pressing beam in a sealing manner; and the eave rafter metal plate is installed on the lower inclined framework. According to the combined roofing system of the metal tiles and themetal eave rafters, the fact that the whole roofing system has better stability and leakproofness can be ensured, the roofing weight can be reduced, and the hidden dangers of deformation of the waterproof board or falling off of the waterproof board and the adapter due to typhoon weather can be eliminated.

Description

technical field [0001] The invention relates to a building roof structure, in particular to a combined roof system of metal tiles and metal eaves rafters. Background technique [0002] At present, antique buildings are mostly constructed in the form of metal roofs and metal eaves. The common roof form of metal tiles and metal eaves rafters is a combination of an independent upper metal tile roof system and an independent lower metal eaves rafter system. , this combined roof has the characteristics of better appearance. However, the following situations are likely to occur during the application process: [0003] (1) For a roof with a large area, the roof system combined with metal tiles and metal eaves and rafters in the prior art will easily cause a safety hazard of instability of the roof support frame due to its heavy 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 raf...

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
