Novel fiber corrugated cement tile

Abstract

The invention discloses a novel fiber corrugated cement tile, the length of which is 800 mm to 1900 mm, and the width of the tile is 500 mm to 900 mm. , The arc distance is 65-130 mm, the wave height is 18-30 mm, the thickness is 4-8 mm, and the wave number is nine. The present invention has basically the same billet forming process as the common asbestos cement small wave tile in the existing market, the length, width and thickness are basically the same, there is no special requirement for the user's use conditions, and the advantages of the existing small wave tile are inherited. The wave type design is reasonable and comprehensive. The performance is good, the effective use area is increased by more than 10% compared with the small wave tile, and the production process can be simplified, energy saving and consumption reduction, and cost reduction. The invention only overlaps one wave to achieve the sealing effect of being able to withstand the strong rainfall in the south, makes the tiles closer to the purlins, is not easy to be damaged, makes the entire roof smoother, and increases the effective use area of ​​the wave tiles.

Description

technical field [0001] The invention relates to a roofing material, in particular to a novel fiber corrugated cement tile. Background technique [0002] Corrugated tiles and small tiles in fiber corrugated cement are a kind of roofing materials, which are produced by using mineral fibers, organic fibers or cellulose fibers and Portland cement or ordinary Portland cement as raw materials. The wave pattern size of the standard medium wave tile is: wave height 31 mm, wave pitch 131 mm, wave number 5.7, and the wave shape size of the standard small wave tile is: wave height 17 mm, wave pitch 63.5 mm, wave number 11.5. [0003] At present, the standard small wave tiles have the following problems: 1. Since the wave height of the small wave tiles is only 17 mm, in order to achieve the sealing effect to withstand the heavy rainfall in the south, the overlap between two adjacent tiles needs two waves to overlap, so the overlap There will inevitably be a gap of more than 6 mm betwee...
