Description

Technical Field

[0001] The present invention relates to the technical field of ancient building roofing engineering, and specifically provides an anti-slip structure for the conical roof of an ancient building based on a pre-embedded metal support system. Background Art

[0002] The conical roof is an important category of traditional ancient building roofs. However, under traditional craftsmanship, the conical roof often has problems such as easy slipping of the tile surface and poor waterproof performance, which cannot meet the comprehensive requirements of durability and functionality in actual use. At the same time, how to construct a roofing system with modern engineering performance while maintaining the appearance of traditional craftsmanship has become a difficult problem that needs to be urgently solved in this field. Among them, regarding the problems existing in the conical roof under traditional craftsmanship, the specific analysis is as follows: 1. In terms of waterproofing, the conical roof under traditional craftsmanship mostly adopts a structural system of wooden base + mud backing layer + tiles. The drainage system of this structure is weak. Its drainage only depends on the overlapping of tiles to form a drainage path, and the joints are easily blocked (porosity < 15%). Moreover, during heavy rain, the accumulated water depth can reach 10 - 15 mm, and lateral thrust is generated, causing the bonded straw-reinforced ash mortar to be lost and resulting in the slipping of the tile surface. 2. In terms of anti-slip, traditional craftsmanship only relies on the overlapping of tiles and the bonding of straw-reinforced ash mortar to resist the risk of tile surface slipping. Since the straw-reinforced ash mortar is an air-hardening material, the wet-dry alternation during the rainy season affects its weather resistance. Over time, it will cause the loss of mortar and the slipping of the tile surface. 3. In terms of cost maintenance, local damage under traditional craftsmanship requires the removal of the entire tile surface. The repair cost reaches 500 - 700 yuan per square meter, and there are also defects such as low bonding strength when the mortar is not completely dry and a long shutdown period for the roof.

[0003] Based on the above, an anti-slip structure for the conical roof based on a pre-embedded metal support system is invented. Summary of the Invention

[0004] To solve the above technical problems, according to one aspect of the present invention, the following technical solutions are provided: An anti-slip structure for the conical roof based on a pre-embedded metal support system, which includes a roof reinforced concrete base layer. A number of galvanized iron supports are pre-embedded at equal intervals in the roof reinforced concrete base layer. A number of concrete water flow strips are arranged at equal intervals on the surface of the roof reinforced concrete base layer, and the galvanized iron supports pass through the concrete water flow strips. A galvanized iron wire mesh frame is provided at the exposed end of the galvanized iron support. A number of perforated tile are tied between two groups of the galvanized iron wire mesh frames by copper wires.
