Color steel sandwich panel roof design(一）

  

  Sandwich panels used in construction, is a new development of building technology, in which there is not a previous set of load-bearing building board, insulation, waterproofing and renovation in one of the functions. Based on this characteristic, in the application of sandwich panels in buildings, we should give full play to consider these characteristics and avoid the problems posed by these characteristics. Sandwich panels used for large-span industrial buildings and public buildings roof, most of them for the plate, purlin structure, sandwich panels are now produced by Sandwich plate processing equipment.
   Roof sandwich panels do not only have to bear the weight of construction to withstand the load, snow load and negative wind loads, it must be connected to the roof purlins, load transmitted beams, columns by the purlins and the like. Therefore, the connection point to the emergence of several plates and purlins; roofing Apart from sheet metal, there are several sorts of flashing accessories. Pan of water between parts, between the pan of water and the plate, between the board and the board, between the member and the surrounding buildings flashings should be linked, which resulted in a large number of connection points. These connection points above process constitutes a key color steel sandwich panel design.
