Problems solved by technology

[0006] As the height of the building increases, the wind pressure increases. The length of the longitudinal overlap is proportional to the wind pressure and inversely proportional to the slope. Such a large overlap length is extremely wasteful and difficult to achieve in actual engineering.

Embodiment Construction

[0020] The present invention is further described in conjunction with the accompanying drawings. For example, a profiled steel tile roof with a slope of 2:100 is designed in a coastal area, and the diameter of the profiled steel tile fastener 2 is 12mm. The upper tile 3 and the profiled steel tile can be selected. The longitudinal lap joint 1 between tiles and tiles 4 has a lap length of 600m. Lay profiled steel tiles on the steel roof truss 5 from bottom to top, and clean the surface at 300mm in the middle of the longitudinal lap. After meeting the bonding requirements, A rubber strip with a width of 40mm and a thickness of 5mm is used as the equal pressure sealing strip 6, which is pasted on the surface of the lower tile 4, and the equal pressure sealing strip 6 is cut at a distance of 10mm at the tile groove 9 to form a drainage groove 7, and then the upper tile is laid 3. Lap according to the length of 600mm, center the isobaric sealing strip, fix the lower tile 4 and upper...

Abstract

The invention is a equal pressure structure waterproof method for pressed steel board tile roof, according to the structure waterproof theory, the equal pressure sealed bar and discharging slot are arranged on the lengthwise connection part, a equal pressure space formed by the upper and subjacent tiles and the equal pressure sealing bar on the connection port position, eliminates the phenomenon rain penetration power and rain capillary absorption formed by the wind pressure on the lengthwise connection part.

Description

technical field [0001] The invention relates to an isobaric structure waterproof method for profiled steel tile roofs. Background technique [0002] The existing profiled steel tile roofs at home and abroad are widely used in industrial buildings with large areas, small slopes, and large spans due to their characteristics of convenient installation, small load, low investment, short construction period, and little influence from building foundation settlement. , such as chemical, metallurgical, building materials and other enterprise factories, in order to reduce the wind load on the building and the load on the roof itself, and reduce the cost of the structure and foundation, the general roof slope is designed to be a small slope between the broken roof and the flat roof , by increasing the length of the profiled steel tiles to improve the integrity of the roof, the profiled steel tiles are usually processed on-site and installed on-site to avoid transportation problems. T...
