Abstract
A large roof boarding, the horizontal one is wavy, its key point is that its wave is big, the wave height is 45-260 mm, the wave distance is 120-700 mm; the wave form is roughly semicircular, and the wave bottom is a plane. The utility model discloses a roof boarding, horizontal bending strength is high, and face length can reach more than 13m, and construction convenience need not the overlap joint, and is fast, saves panel, and the wholeness is good, and the airtight gas leakage is favorable to taking precautions against earthquakes, dampproofing, heat preservation, and accommodation is wide, is the light-duty roofing building material of an ideal.
Description
The utility model belongs to the building material technology scope, particularly relates to a kind of large roof slab.
In the prior art, no matter the light-weight roof slab of what material all is the ripplet formula, wave height generally at 25-33mm, the pitch of waves about 63-90mm, its rupture strength is poor, plate face length degree generally should not surpass 3m.The light-weight roof slab of this small-sized ripplet formula needs overlap joint during construction, globality is poor, be unfavorable for shockproof, the ventilative gas leak is unfavorable for heat-holding dampproof, and construction simultaneously is convenient inadequately, speed is slow, waste sheet material only should be applicable to general factory building, warehouse, temporory structure, can not be applicable to industrial premises, and the warehouse etc. that the restriction of humidity, heat-retaining condition is arranged, the scope of application is little.
Task of the present utility model provides a kind of rupture strength height, easy construction, need not overlap, large roof slab applied widely, to overcome the above-mentioned shortcoming that prior art ripplet formula roof panel exists.
Task of the present utility model is big according to ripple, the principle design that laterally rupture strength is high realizes that its horizontal corrugate is as sine wave, trapezoidal wave etc., its main points are that its ripple is big, wave height is 45-260mm, and the pitch of waves is 120-700mm, can be selected according to length requirement, when plate face length degree requires when big, its wave height, the pitch of waves can be corresponding big, plate face dimensional requirement hour, and wave height, the pitch of waves then can be littler.
Above-mentioned said wavy, when in general laterally becoming sinusoidal wave, its rupture strength height, but during construction, the contact area between its bottom surface and the support is little, is unfavorable for load-bearing; Laterally in echelon during ripple, the contact area between bottom surface and the support is big, helps the even distribution of load, and weight capacity is strong, but the corresponding not as above person of rupture strength.For integrated application the two advantage, the horizontal waveform of the utility model roof panel can be to be roughly semicircle, wave base is the plane, as shown in the figure, in order to strengthen its rupture strength, and make appearance and modeling elegant in appearance, and said wave base, its width can be the wide 1/4-3/5 of said semicircle ripple.
Accompanying drawing is a transverse cross of the present utility model.
Roof boarding transverse wave of the present utility model is big, and High anti bending strength is more than the plate face length Du Keda 13m, it is easy to use to construct, and need not overlap, and speed is fast, save sheet material, the roofing good integrity, stuffy gas leak is conducive to shockproof, moistureproof, insulation, applied widely, elegant in appearance, durable, be a kind of desirable Large-scale Roof construction material.
Claims (2)
1, a kind of large roof slab, laterally corrugate is characterized in that its ripple is big, and wave height is 45-260mm, and the pitch of waves is 120-700mm; It is semicircle that waveform becomes substantially, and wave base is the plane.
2, roof panel according to claim 1 is characterized in that said wave base, and its width is the wide 1/4-3/5 of said semicircle ripple.
