Description

Improved roof sheet tile

The present invention relates to a kind of improvement of roof sheet tile or the improvement relevant, relate to especially and a kind ofly profile is conformed to and the improvement or the relevant with it improvement of interlockable tile with a kind of roof sheet tile.

" profile conforms to " used herein, a speech meaned a kind of tile with a shaping upper surface, for example, and two semicircle arches, protruding roll forming or analogous shape.This tile has the shaping sidepiece usually on each side of central shaped portion, the sidepiece of shaping has the groove that notch faces upward or downward respectively, so that in use, makes the every tile tile interlocking adjacent with the side on the roof.

Fig. 1 shows existing in the art common tile.In order to cover the upper surface of this watt, its bottom shape must be identical with upper surface.In other words, this means what tile thickness (lead edge portion) in vertical direction always equated.The radius R of the arcuate part of upper surface is identical with the radius R of bottom surface arcuate part, but the center of these two radiuses is in differing heights, and its difference in height equates with tile thickness.Yet described as former manual background technology part, this design of tile does not exist the gap when overlapping except making tile, and structural strength etc. is not had substantial role, makes the lead edge portion of tile have excess weight on the contrary.

The objective of the invention is to overcome the existing existing shortcoming of tile, reduce the unnecessary weight of tile, save material, and roof sheet tile as indicated above is provided easily.

For achieving the above object, the invention provides a kind of roof sheet tile, described tile comprises an outstanding central forming section, outstanding interlocking sidepiece on the described tile side and the depressed part between each sidepiece and described central forming section, and described tile also has a leading edge face, described leading edge face traverse described tile width and when using towards deck, it is characterized in that, the thickness of described leading edge face changes, and promptly gradually becomes big than light filling bar to adjacent with described interlocking sidepiece thicker section from corresponding with described central forming section.

Preferably, the thickness of the leading edge face of tile of the present invention changes at the tile width, promptly thinner with described central portion corresponding position, thicker with the depressed part corresponding position, and the thickness of described interlocking sidepiece adjacent between preceding two kinds of thickness.

Preferably, tile of the present invention in use, the leading edge face thickness of described depressed part correspondence less than the interlocking sidepiece of adjacent tiles in conjunction with thickness.

Preferably, the thickness approximate center forming section of the leading edge face corresponding with the tile depressed part corresponding than light filling bar thickness half with the corresponding thicker section thickness sum of described adjacent tiles interlocking sidepiece.

Preferably, aforesaid central forming section is thinner on tile 1/3rd length at least, is preferably on the whole length of tile all thinner.

In addition, its outstanding central forming section of tile of the present invention comprises one along the last forming face on the tile length direction, the similar corresponding top ridge of going up forming face that the interlocking sidepiece of adjacent tiles was produced when its top ridge was lower than by use.

Preferably, tile of the present invention is two semicircle arches, protruding roll forming.

The present invention includes also roof by above-mentioned tile covered, under user mode, every level row tile is arranged tile with adjacent level and is arranged in the half lap scarf joint mode, and the tile in a row tile with it on and/or adjacent under it respectively arrange the overlapping head of tile and afterbody is identical or essentially identical in conjunction with overlapping thickness.

The outward appearance on roof can be that the depressed part thickness of each row tile on the roof is constant, and the arcuate part of the tile in adjacent each row and independent each row has thick-thin, thick-thin outward appearance.

Below in conjunction with accompanying drawing, with way of example one embodiment of the present of invention are described in detail, wherein:

Fig. 1 is the end-view of prior art roof sheet tile;

Fig. 2 is the top perspective view of roof sheet tile of the present invention;

Fig. 3 is the end-view from vertical being seen two roof sheet tiles of tile;

Fig. 4 is the top perspective view that is used for many tiles on the roof.

As shown in Figure 1, the thickness of the forward edge of traditional concrete roof sheet tile remains unchanged at the width of tile, there is the gap between each tile when preventing to be stacked on the roof, and structural strength of tile etc. there is not substantial effect, the weight of tile is increased, and the thickness that suitably reduces the tile forward edge can make tile weight saving; Therefore, need provide a kind of forward edge thickness less and can guarantee not exist when overlapped the tile in gap, make required composition material, cement, filler and the pigment of tile thereby save.

As Fig. 2, shown in 3,4, the invention provides a kind of so interlockable shaping roof sheet tile 10, the tile shown in the figure is " protruding roller " shape.

The vertical view of this tile 10 is roughly rectangular, comprise left and right shaping

sidepiece

12,14, central forming section 36, the depressed part 41 and 42 between shaping

sidepiece

12,14 and the central forming section 36, wherein, the top ridge 38 of central forming section is lower than the respective top ridge 40 of sidepiece 12 basically.

As conventional art, sidepiece 12 has a bottom surface 16, and

flange

18,20 and

groove

22 and 24 of longitudinal extension are arranged on it, and sidepiece 14 has an end face 26, and

flange

28,30 and

groove

32 and 34 of shape and sidepiece 12 upper grooves and flange complementation are arranged on it.During use, flange on flange on each tile sidepiece and groove and the adjacent tiles sidepiece and groove interlocking.

Different with the prior art tile is that the thickness of the leading edge face 44 of tile 10 of the present invention changes on the tile width.Concrete, the thinner thickness of the leading edge section 441 corresponding on this leading edge face 44 with central forming section 36, the leading edge section 442,442 corresponding ' thicker with depressed part 41,42, the leading edge section 443,443 corresponding with

sidepiece

12 and 14 adjacent parts ' thickness between preceding two kinds of thickness.Specifically ask for an interview the leading edge section 441 corresponding with central forming section 36, the thickness at this place is thinner than remainder on the tile, the bilge redius R at this place ₁With the top radius R ₂Difference, R ₂Compare R ₁Long, and two radiuses have identical center.So make such two tiles with its center between not only overlapping and tile but also not exist the mode in gap to place be impossible.Do not deposit the gap when making two tiles overlapping,

sidepiece

12 and 14 upper and lower limit have another form, and promptly bilge redius is long R ₂, the top radius is short R ₁, and the center is on differing heights.Such two tiles must be placed on the roof in the half lap scarf joint mode, and in the case, radius is R ₂It is R that the bottom surface of last tile (corresponding to part 12 and 14) is put in radius ₂On the upper surface of following tile (should be in part 36 to 8), radius is R ₁The situation identical (soffit corresponding to part 36 is positioned on

part

12 and 14 upper surfaces) of part.The upper surface of arcuate part has radius R alternately ₁And R ₂Otherwise the bottom surface of this part has radius R alternately ₂And R ₁Adopt this structure, can make the thinner thickness of central shaped portion 36, produce the gap simultaneously in the time of also can not making each tile overlapping.

In addition, can all be consistent at the whole length direction of tile 10 corresponding to the thickness of the leading edge face section 441 of central forming section 36, perhaps thinner on its partial-length, as thinner on 1/3rd length.

In addition, corresponding to the leading edge section 442,442 of depressed part ' thickness be that leading edge section 441 thickness add the leading edge section 443 adjacent with

sidepiece

12,14, half of 443 ' thickness sum, as can be seen from Fig. 3, under user mode, two overlapping depressed part 41,42 thickness equal or are substantially equal to central forming section 36 thickness and interlocking

sidepiece

12,14 thickness sums.

Tile of the present invention in use only can cover on the roof in the half lap scarf joint mode.See Fig. 3 and 4, its result of use is extremely attractive, and the thickness of the tile depressed part of aligning is consistent, and above the roof as seen, the roll forming part outward appearance of tile all is thick one thin, thick one thin pattern on direction in length and breadth.

Tile 10 of the present invention can be made by the concrete roof sheet tile processing line of routine, wherein, tile mortar in the hopper is pressed through under a forming rolls and slide block, and on series of identical roof tile pallet, forming tile mortar band, the shape of tile and thickness are by the upper surface and the decision of the slit between forming rolls and the slide block soffit of pallet.Then, cut formed mortar band, thereby on pallet, form discontinuous tile.

Tile with structure of the present invention can reduce tile weight significantly, for example can alleviate 15% weight at most, and the intensity of tile is evenly distributed on the roof with effective and efficient manner.

Should be appreciated that within the scope of the invention and also can make other modification, and the also available clay of tile of the present invention or other suitable mixed material are made.
