Plate body material adoption yield strength is not less than 235MPa's galvanized steel sheet, and thickness is not less than 0.8mm. The effective width of plate body is 919mm, expandes width 1250mm, goes out the board rate and reaches 73.5%. The utility model discloses beneficial effect is: adopt reasonable board type, the wave height is moderate, and it is high that the board type goes out the board rate, energy -conserving raw and other materials, it is big that the face covers the width, and the piece number of required panel reduces relatively, has consequently practiced thrift time and cost in transportation and the installation, special design's sub - tongue -and -groove and female tongue -and -groove make overlap joint and installation prompt very fast, bear the weight of the dynamic height, permit the design span big, the quantity of purlin in the economy system, the crest width is big, and the opening is little, the installation of be convenient for insulation material and flexible waterproof coiled material, the self -tapping screw's that is used for fixing quantity has been saved to the great relatively pitch of waves than similar board type.
Description
Technical field
The utility model relates to roof structure technical field.Belong to a kind of individual layer prepared roofing special-purpose steel base plate.
Background technology
That individual layer coiled material Roof system has is good from heavy and light, waterproof thermal-insulated performance, quick construction, easily maintenance, life-span long, the long-term excellent feature of cost performance.Wherein at steel structural roof, the leakage problem of traditional roof system, cold bridge condensation trouble, noise problem, many curved surface structures problem etc. thoroughly can be solved.In view of the remarkable advantage that it is many, individual layer coiled material Roof system is accepted by domestic market accreditation rapidly, and obtain and develop fast, be widely used in the object of construction production such as stadiums, exhibition hall, airport, industrial premises, logistics center, market, hospital, railway terminal.
But the steel sole plate play supporting role in existing individual layer coiled material Roof system, it is not strong to there is professional and complete property in it, and plate production rate is low, designs uneconomical, waste nail, the problems such as construction is inconvenient, construction quality is poor.
Utility model content
The technical problem that will solve of the present utility model is, for above-mentioned deficiency, provides a kind of reasonable in design, constructability, economy, efficiently individual layer prepared roofing special-purpose steel base plate.
For achieving the above object, the utility model is by the following technical solutions:
A kind of individual layer prepared roofing special-purpose steel base plate, it includes plate body, it is characterized in that, is provided with sub-tongue and groove in the side of plate body, is provided with female tongue and groove at the opposite side of plate body, and plate body interlocks is provided with protruding crest and recessed trough.
Wherein, described plate body is made up of six crests, six troughs, a sub-tongue and groove and female tongue and grooves, forms wider coverage rate; Plate body material adopts yield strength to be not less than the galvanized steel plain sheet of 235MPa, and thickness is not less than 0.8mm.
Wherein, the sub-tongue and groove of plate body both sides and female tongue and groove, adopt forming press that folding on steel plate is formed sub-tongue and groove, forming press will be rolled under steel plate and is bent to form female tongue and groove of arc, be convenient to grafting fasten, female tongue and groove fastens the sub-tongue and groove of adjacent panels, forms the good overlap joint mouth fastened.
Wherein, the crest on described plate body and trough, suppressed by forming press and form the recessed plate shape of epirelief, crest is wide, and trough is narrow, and the pitch of waves is greater than 150mm, and wave peak width is greater than 80mm, and crest surfacing, constructability; Wave height 35mm, reasonable in design, meet individual layer coiled material Roof system requirement for bearing capacity.
Wherein, the effective width of described plate body is 919mm, and spreading width 1250mm, plate production rate reaches 73.5%.
The beneficial effects of the utility model are: individual layer prepared roofing special-purpose steel base plate adopts reasonable template, and wave height is moderate, and template plate production rate is high, energy-conservation raw material; Plate face cover width is large, and the block number of required panel reduces relatively, has therefore saved the time in transport and installation and cost; The sub-tongue and groove of particular design and female tongue and groove make overlap joint and install very quick; Bearing capacity is high, allows design span large, the consumption of purlin in saving system; Wave peak width is large, and opening is little, is convenient to the installation of heat insulating material and flexible waterproof sheet; The relatively large pitch of waves, saves the quantity for fixing self threading pin than similar template.
Below by accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model individual layer prepared roofing special-purpose steel base plate.
Fig. 2 is the overlap joint schematic diagram of the utility model individual layer prepared roofing special-purpose steel base plate.
Detailed description of the invention
Shown in Figure 1:
A kind of individual layer prepared roofing special-purpose steel base plate, it includes plate body 1, is provided with sub-tongue and groove 2 in the side of plate body 1, is provided with female tongue and groove 3 at the opposite side of plate body 1, and plate body 1 interlocks is provided with protruding crest 4 and recessed trough 5.
Wherein, described plate body 1 is made up of six crests, 4, six troughs, 5, sub-tongue and groove 2 and a female tongue and groove 3, forms wider coverage rate; Plate body 1 material adopts yield strength to be not less than the galvanized steel plain sheet of 235MPa, and thickness is not less than 0.8mm.
Wherein, the sub-tongue and groove 2 of plate body 1 both sides and female tongue and groove 3, adopt forming press that folding on steel plate is formed sub-tongue and groove, forming press will be rolled under steel plate and is bent to form female tongue and groove 3 of arc, be convenient to grafting fasten, female tongue and groove 2 fastens the sub-tongue and groove 2 of adjacent panels, forms the good overlap joint mouth fastened.
Wherein, the crest 4 on described plate body 1 and trough 5, suppressed by forming press and form the recessed plate shape of epirelief, crest is wide, and trough is narrow, and the pitch of waves is greater than 150mm, and wave peak width is greater than 80mm, and crest surfacing, constructability; Wave height 35mm, reasonable in design, meet individual layer coiled material Roof system requirement for bearing capacity.
Wherein, the effective width of described plate body 1 is 919mm, and spreading width 1250mm, plate production rate reaches 73.5%.
