Description
Background technology
Invention field
[0001] in one embodiment, the present invention relates to the fibre reinforced cement goods, more specifically, relate to a kind of lightweight, durable and nailable fibre reinforced cement goods, these fibre reinforced cement goods can conveniently be installed as roofing tile.
Description of Related Art
[0002] for example slates and shingle are that two kinds of present world wides use comparatively general roofing goods (roofing article) for natural roof cladding.Yet there is shortcoming in these two kinds of goods.The slate roofing material is being exploited, is being shaped and installing very expensive.Shingle is typically made by mothproof China fir, and owing to the attractive in appearance and easy for installation of them receives an acclaim, but a small amount of supply of high-quality China fir and new building acts restriction are promoting to have the demand of the equivalent material of shingle outward appearance.
[0003] therefore, the concrete roof goods, fibre reinforced cement roofing tile for example has been developed into the substitute of shingle and slates.Yet the high-density that traditional fiber reinforced cement board roof cladding is had makes their extremely difficult nailings.Therefore, they typically are manufactured to the nail hole that has prebored hole.Yet, the shortcoming in prebored hole nail hole is, if preboring nail hole not with roof plate on anchor point align, then the roofing installation personnel does not almost have handiness, especially so-called " great-jump-forward coverture (skip-sheathing) " wherein covers the mode that sheet material is spaced and makes them can not align with prebored hole.For solving this shortcoming, the roofing installation personnel is filled the interval that great-jump-forward covers roofing usually with extra wrapper plate, and this has further increased roof weight and has prolonged the settling time.
[0004] affact when watt going up when pressure and pulling force, present existing cement composite material and concrete roof tile are also broken easily and are damaged.These concrete and cement roof material, especially thistle tile, innately frangible, and when walking in the above, be easy to split and breakage.Some cementitious composite roof claddings can have enough initial toughness and break with opposing in installation process, but along with always can become fragile working life, and become and can not walk.In order to solve this difficult problem, many manufacturerss recommend to use walking liner (walking pad) at present, walking sheet material, or below roof cladding, use polyurethane foam, help to distribute those because the maintenance purpose need be passed the personnel's on roof weight.Yet these extra protections are inconvenient and implement the cost costliness.
[0005] in addition, traditional concrete or cement composite material roofing tile make in the obducent installation of clashing on ridge (hip) or ridge (ridge) zone especially difficult.The roof generally is to make with different gradient (pitch) according to the architectural practice of locality.In order to cover ridge or ridge zone in an opposite direction, the hard concrete tile must be formed several different dihedrals, and in order to cooperate multiple roof style, manufacturers must have multiple dihedral.Other cement composite material roofing tile needs location and nailing conscientious and consuming time, and purpose is that ridge is clashed in assurance and the ridge zone is covered suitably.
[0006] roof cladding, especially slates, shingle or tile are typically installed in the mode of overlap joint to highest point or ridge from the base of roof line.If the end of roof covering row does not overlap any object, it will with difference thereon the angle of wicker angle lie on the roofing board.This not only can not make us accepting on attractive in appearance, and is clumsy architectural practice, because wicker is not supported by first row's object, and is easy to break.For overcoming this defective, for the roofing setter, traditional practice is to get slates, shingle or a tile, cuts from the centre, forms cant strip or eaves shop fixtures layer.Cant strip be placed in each row watt end below, make angle of end row and roof boarding orientation, this angle is approximately equal to the angle of wicker.Although this operation is reasonably from attractive in appearance and performance standpoint, its waste material and consuming time.
[0007] according to top described, therefore expectation provides a kind of light-weight, middle density to low-density fibre refinforced cement material, this material can nail on nail and not ftracture, expose to the open air to use and keep its initial toughness and walking afterwards, freeze/melt and keep its bending or tensile strength after exposing to the open air, and it is good to raise in the test (wind-uplifttest) performance at wind.In addition, also expectation provides a kind of light-weight, durable, nailable roofing goods, the similar natural shingle of these roofing goods, slates or other traditional roof cladding.And expectation provides the fibre reinforced cement roofing goods that can be used as ridge in an opposite direction or ridge coverture or cant strip.
[0008] overcome or improve at least a shortcoming of prior art, or the surrogate that provides usefulness is a purpose of the present invention.
