Description
Technical field
The present invention relates to a kind of metal roofing board.In addition, the invention still further relates to a kind of forming method of metal roofing board.
Background technology
Along with the development of China's urban whole level, people are also more and more general to attractive in appearance, the safety of Indoor environment, peace and quiet, insulation, ventilation requirement, and therefore composite metal Roof system is also used more and more in the buildings such as all types of industries, physical culture, amusement, exhibition hall, retail supermarket.The existing metal Roof system of current this kind of building adopts the metal roofing board of inner support anchor structure usually, to obtain attractive in appearance and firm instructions for use.Metal roofing board is the main structural components that steel building field is commonly used.
Existing metal roofing board is by first arranging some holders, again the buckling parts of adjacent two pieces of roof panel is fastened on relatively the outside of holder, because the plate outside of belly of roof panel is long-pending larger, therefore its non-deformability is poor, even if arrange some reinforcing ribs on roof panel, its non-deformability is also general.When being subject to the External Force Actings such as blast, the loads such as negative blast can make the plate abdomen generation deflection deformation of metal roofing board, serious plate abdomen distortion can cause easy opening between the buckling parts of two pieces of roof panel, opening can cause the permanent deformation of roof panel further and bring serious consequence, the phenomenon such as leaking easily appears in roofing, air intake.
As shown in Figure 1, for existing metal roof board system to deform the schematic diagram lost efficacy by negative wind load, under the effect of negative wind load, not only the plate abdomen distortion of roof panel is upwards arched upward, and the distortion of roof panel makes buckling parts ftracture, even can make the holder occurred level displacement of roof panel, and then make to produce between roof panel and holder to thread off, roof panel be departed from completely fixing.As shown in Fig. 2 (a) ~ (c), be the process schematic that existing single piece of metal roof panel deforms by negative wind load, under the effect of negative blast, the plate abdomen distortion of roof panel is arched upward gradually, and the final holder that departs from is threaded off.Therefore the Wind-Pressure Resistance ability of existing metal roofing board is poor, and especially the non-deformability of plate abdomen poor easily causing, permanent deformation occurred.
Summary of the invention
Technical problem to be solved by this invention is the deficiency overcome in prior art, provides a kind of plate abdomen good rigidity, resistance to deformation metal roofing board that Wind-Pressure Resistance ability is strong.
In addition, the present invention also provides a kind of forming method of resistance to deformation metal roofing board.
The technical scheme that resistance to deformation metal roofing board of the present invention adopts is: described resistance to deformation metal roofing board comprises base plate, founds rib, right vertical rib with the integrated left side of described base plate, rib and the described right side are stood in a described left side, and to found rib suitable, the plate abdomen of described base plate is provided with resistance to deformation and strengthens district, described resistance to deformation is strengthened district and to be gathered several protruding and pits, and described projection is with the mutual interval successively of described pit and be uniformly distributed.
On described base plate except fringe area, be described resistance to deformation and strengthen district.
Described projection is identical with the shape of described pit.
With described base plate for interface, the height dimension of described projection is H, and the depth dimensions of described pit is L, H=L.
Described projection and described pit are the pineapple spike-like structures of pineapple surface.
Or described projection and described pit distribute in " H " shape.
Or described projection and described pit Cheng “ Swastika " shape distributes.
The technical scheme that the forming method of resistance to deformation metal roofing board of the present invention adopts is: comprise the following steps:
(1) rib of slab is shaping: by roof panel forming machine, and in the left and right sides of described base plate by cold bending process, one machine-shaping goes out a described left side and founds rib and rib is found on the described right side;
(2) resistance to deformation reinforcement district is shaping: by squeeze moulding process, process densely covered described projection and described pit at the plate abdomen of described base plate, forms resistance to deformation and strengthens district.
The invention has the beneficial effects as follows: because resistance to deformation metal roofing board of the present invention comprises base plate, founds rib, right vertical rib with the integrated left side of described base plate, rib and the described right side are stood in a described left side, and to found rib suitable, the plate abdomen of described base plate is provided with resistance to deformation and strengthens district, described resistance to deformation is strengthened district and to be gathered several protruding and pits, and described projection is with the mutual interval successively of described pit and be uniformly distributed, the present invention strengthens district by arranging resistance to deformation at the plate abdomen of described base plate, be uniformly distributed by the mutual interval successively of described projection and described pit of gathering, greatly enhance the rigidity that described resistance to deformation strengthens district, the Rigidity and strength of whole base plate is increased greatly, can the distortion of effective preventing board abdomen, avoid plate abdomen and be out of shape opening between the buckling parts that may cause, avoid the permanent deformation of roof panel, thus decrease metal Roof system and leak, the generation of the phenomenons such as air intake, therefore the plate abdomen good rigidity of resistance to deformation metal roofing board of the present invention, Wind-Pressure Resistance ability is strong,
Forming method due to resistance to deformation metal roofing board of the present invention is only after the step that traditional metal roofing board rib of slab is shaping, set up resistance to deformation strengthen the shaping step in district, and therefore its method is easier, and cost of production is lower.
