Abstract

The utility model discloses a porous cement pantile and relates to the technical field of cement pantile manufacturing. Spherical concave holes are formed in at least one side of the porous cement pantile. When the porous cement pantile is unfolded, optional three adjacent concave holes form an isosceles right triangle. The distance between the centers, which are close to and parallel with the edges of the porous cement pantile, of the concave holes and the edges of the porous cement pantile ranges from 10-20mm, the diameter of each concave hole is 3-12mm, and the maximum depth of each concave hole is half to two thirds of the thickness of the porous cement pantile. Under the circumstance that cost of the porous cement pantile is lowered while strength of the porous cement pantile is unchanged, cold shrinkage crack of the porous cement pantile is reduced.

Description

The honeycombed cement pantile

Technical field

The utility model relates to cement corrugated tile manufacturing technology field, especially a kind of honeycombed cement pantile.

Background technology

The material of producing on the market at present that is used for covering roofing, price is cheapest to be cement waveform asbestos shingle, the side of this cement waveform asbestos shingle generally all is comparatively smooth curved surface, this cement waveform asbestos shingle is layered on the top in house, the shortcoming that a maximum is arranged is to meet cold shrinkage cracking, and is especially particularly outstanding in this phenomenon of northern area; The approach that solves cement waveform asbestos shingle cracking at present has two kinds, the one, the consumption of asbestos in the increase cement asbestos shingle, the 2nd, the density of reduction cement asbestos shingle, the former causes cement waveform asbestos shingle cost to raise, and the latter causes the second-rate of cement waveform asbestos shingle.

Summary of the invention

The purpose of this utility model provides a kind of honeycombed cement pantile, this honeycombed cement pantile can significantly reduce the phenomenon that cement corrugated tile is met cold shrinkage cracking not improving cement waveform asbestos shingle cost and not reducing under the situation of cement waveform asbestos shingle intensity.

In order to address the above problem, the technical solution adopted in the utility model is:

This honeycombed cement pantile is distributed with the dome shape shrinkage pool at least one side.

In the above technical scheme, further scheme is: after the expansion, three adjacent described shrinkage pools are the isosceles right triangle distribution arbitrarily, be 10 ~ 20mm near the center of each limit of honeycombed cement pantile and the described shrinkage pool that is arranged in parallel along each limit to the distance range on each limit of described honeycombed cement pantile, the diameter of described shrinkage pool is 3 ~ 12mm, and the depth capacity of described shrinkage pool is 1/2 ~ 2/3 of described honeycombed cement pantile thickness.

In the above technical scheme, further scheme is: described honeycombed cement pantile length range is L=600mm ~ 3000 mm, and width range is B=400mm ~ 1200 mm, and thickness range is δ=3 mm ~ 10 mm, the wave height scope is h=15 mm ~ 55 mm, pitch of waves scope t=60 mm ~ 185 mm.

Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:

1, the weight of this honeycombed cement pantile unit area reduces, and intensity increases.

2, this honeycombed cement pantile is met cold shrinkage cracking phenomenon and is reduced significantly.

3, making every this honeycombed cement pantile material therefor reduces.
