Prefabricated Panel House Roof Ridge Raising

The roof ridge raising of prefabricated panel houses can be achieved through methods such as red brick masonry, color-steel construction, light steel structure, wooden structure, and double-layer structure. Details are as follows:

1. Red Brick Masonry Ridge Raising: This method involves using red bricks for masonry. After the structure is built, purlins are installed, followed by the laying of red tiles. Red bricks offer good thermal insulation properties, resulting in a roof with relatively good insulation and a longer service life. However, red brick masonry requires certain construction skills and time, and the overall weight is relatively large, imposing certain requirements on the foundation bearing capacity of the house.
2. Color-Steel Construction Ridge Raising: Color-steel is used for construction, which is relatively simple and quick. However, roofs made of color-steel materials have obvious drawbacks, such as poor thermal insulation in winter, resulting in lower indoor temperatures; and strong heat absorption in summer, leading to higher indoor temperatures and reduced living comfort.
3. Light Steel Structure Ridge Raising: Light steel structures have the advantage of being lightweight, effectively reducing the load on the overall house structure. At the same time, the design of light steel structures is flexible, allowing for the creation of aesthetically pleasing roof shapes that are both practical and visually appealing.
4. Wooden Structure Ridge Raising: Wood is used as the beam, on which fir boards are laid, followed by the sequential laying of waterproof materials, insulation boards, steel wire mesh fine aggregate concrete protective layers, and finally asphalt decorative tiles. This structure has multiple layers, providing good waterproofing and thermal insulation. However, the construction process is relatively complex, with high requirements for the quality of the wood and construction techniques.
5. Double-Layer Structure Ridge Raising: First, a prefabricated panel sloped roof is laid on the roof surface, and then wooden purlins and a tile roof are installed on top to form a double-layer structure. This structure offers certain advantages in terms of heat insulation and waterproofing, effectively improving the thermal insulation and waterproofing performance of the roof.

It should be noted that standard prefabricated panels are of 300 modulus. Prefabricated panels with a span exceeding 4200 should be used with caution. Additionally, when laying prefabricated panels on a sloped roof, inclined laying generates a certain amount of horizontal force, which may cause the prefabricated panels to slide, especially when the slope is steep. Moreover, waterproofing of the prefabricated panel roof is also a key issue that requires attention.
