Description

Technical Field

[0001] This utility model relates to the field of ancient building roof engineering technology, specifically to an anti-slip structure for a pyramidal roof based on a pre-embedded metal support system. Background Technology

[0002] Pyramidal roofs are an important category of traditional Chinese building roofs. However, traditional pyramidal roof construction often suffers from problems such as tiles slipping easily and poor waterproofing, failing to meet the comprehensive requirements of durability and functionality in practical use. Furthermore, how to construct a roof system with modern engineering performance while maintaining the appearance of traditional construction has become a pressing challenge in this field. The specific problems of traditional pyramidal roof construction are analyzed below:

[0003] 1. In terms of waterproofing, traditional pyramidal roofs often use a construction system of wood base + mud backing + tiles. This structure has a weak drainage system, which relies solely on the overlapping of tiles to form a drainage path. The joints are prone to blockage (porosity <15%), and during heavy rain, the water depth can reach 10-15mm, generating lateral thrust that causes the bonding straw and mortar to be lost, resulting in the tiles slipping off.

[0004] 2. In terms of anti-slip, traditional processes rely solely on overlapping tiles and bonding with straw-reinforced mortar to resist the risk of tile slippage. However, since straw-reinforced mortar is an air-hardening material, the alternating wet and dry conditions during the rainy season affect its weather resistance. Over time, this can lead to mortar loss and tile slippage.

[0005] 3. In terms of cost maintenance, under traditional processes, local damage requires the removal of the entire roof tile, with repair costs reaching 500-700 yuan / ㎡. In addition, the bonding strength is low after the mortar has not dried completely, and the roof is not used for a long period of time.

[0006] Based on the above, an anti-slip structure for a pyramidal roof based on a pre-embedded metal support system is invented. Utility Model Content

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A non-slip structure for a pyramidal roof based on a pre-embedded metal support system includes a reinforced concrete base layer of the roof. Several galvanized iron supports are pre-embedded at equal intervals in the reinforced concrete base layer of the roof. Several concrete runners are provided at equal intervals on the surface of the reinforced concrete base layer of the roof, and the galvanized iron supports pass through the concrete runners. The exposed ends of the galvanized iron supports are provided with galvanized iron wire mesh frames. Several perforated tiles are tied between two sets of galvanized iron wire mesh frames by copper wire.

[0009] As a preferred embodiment of the anti-slip structure for a pyramidal roof based on a pre-embedded metal support system described in this utility model, wherein: straw-reinforced mortar is provided between the concrete water-guiding strip and the perforated tile to bond the perforated tile to the concrete water-guiding strip.

[0011] As a preferred embodiment of the anti-slip structure for a pyramidal roof based on a pre-embedded metal support system described in this utility model, the galvanized wire mesh frame is composed of several spliced ​​galvanized wires, and the copper wire passes through the perforated tile and is wrapped around the galvanized wire.

[0012] As a preferred embodiment of the anti-slip structure for a pyramidal roof based on a pre-embedded metal support system described in this utility model, wherein: the top of the concrete water-guiding strip is provided with straw reinforcement mortar, and the straw reinforcement mortar is designed to be arc-shaped.

[0013] As a preferred embodiment of the anti-slip structure for a pyramidal roof based on a pre-embedded metal support system described in this utility model, wherein: the outer side of the straw-fiber mortar is provided with cylindrical tiles, and the cylindrical tiles are designed to be arc-shaped.

[0014] As a preferred embodiment of the anti-slip structure for a pyramidal roof based on a pre-embedded metal support system described in this utility model, tung oil putty is provided between the barrel tile and the perforated plate tile.

[0015] Compared with existing technologies:
