Description

Technical Field

[0001] The invention belongs to the technical field of thermal insulation roofs, and in particular relates to a hollow thermal insulation roof of an assembled building. Background Art

[0002] In prefabricated steel structure villas, the traditional installation methods of building sloping roofs mainly include: prefabricated component installation, PC composite panel installation, welding installation, and clamp installation.

[0003] Installation of prefabricated components: Large roof components (such as steel roof trusses and insulation panels) are prefabricated in the factory and then assembled on site (by tower crane) using special large transport vehicles.

[0004] Disadvantages: 1. High transportation cost and easy damage during long-distance transportation; 2. Difficulty in lifting, requiring large-scale machinery to cooperate, and high requirements for the flatness of the site; 3. Complex on-site adjustments. If the component size exceeds the error range, on-site cutting or welding is required, which affects the construction period.

[0005] PC composite panel installation: The overall roof structure is formed by combining prefabricated concrete composite panels with cast-in-place concrete layers. The prefabricated panels are hoisted by special hoists and installed from the middle to the surrounding areas.

[0006] Disadvantages: 1. The weight is too large. The overall thickness of the composite floor is between 140-180mm, and the weight per unit area is about 400KG / m²; 2. The construction process is complicated, and it is necessary to accurately control the lifting angle and the construction quality of the cast-in-place. 3. The cost is relatively high.

[0007] Welding installation: The main and secondary roof keels are welded on site.

[0008] Disadvantages: 1. High risk of deformation. High welding temperature causes local shrinkage of steel, which may cause structural warping. 2. Complex quality inspection and high cost of dealing with weld defects. 3. Dangerous high-altitude operations. Welding can easily cause fires. Workers need to be certified to work, and labor costs are high.

[0009] Clamp installation: The components are installed on the roof with the help of clamps.

[0010] Disadvantages: 1. Limited bearing capacity, only suitable for light roofing materials. 2. Poor durability, the fixture is prone to corrosion due to long-term exposure, and requires regular maintenance. 3. Weak waterproofing, the tile overlap is prone to leakage. Summary of the invention
