Find a joint electronic M1.5.4 type ECU application system wiring harness and layout Thank you, anxious! The
1.5M is the thickness of the board? If it is, in view of the large amount of concrete from the major, then the long spot of the short spot of the prisoners need to pay special training program reported to the chief engineer or expert approval, which is also the most important [template bearing capacity design calculation], proof of design Of the construction program to meet the bearing capacity of concrete to ensure that the template and its bracket should have sufficient carrying capacity, stiffness and stability, can reliably withstand the weight of pouring concrete, side pressure construction load. In recent years, because the construction of non-standard template led to the collapse of a lot of scaffolding, hope to be cited
Not even if you are cheap to say that you are angry, and a ticket stare on the
According to the intrinsic composition of insulation materials can be divided into: inorganic insulation materials and organic insulation materials! Fire rating A is a non-burning point with the insulation effect of materials, materials. Class A non-combustible materials have the characteristics of low density, low thermal conductivity, high pressure capacity, convenient construction, economical and durable. They are widely used in thermal insulation materials and industrial industries such as hot pipes, thermal equipment and other industrial piping equipment and industrial buildings And the civil building envelope structure of the insulation, insulation, sound absorption materials. Because of its good thermal stability, and more for the steel structure of the fire protection coating material. Fire rating B1 level is a flame retardant insulation material, is determined according to the fire resistance of the material, in addition, different parts of the material division is also different! Burning performance: refers to the material and / or products in case of fire burning all the physical and / or chemical changes, that is, the fire reaction characteristics. Fire rating B2 is a combustible insulation material also known as flame retardant materials, mostly organic insulation materials, add the right amount of flame retardants. More common for EPS expansion polystyrene board and XPS extruded polystyrene board, that is, we often say that general board. This material is low in ignition and releases a lot of harmful gases during the combustion process. Fire rating B3 is a flammable insulation material, this is more common as the main material of polystyrene foam insulation material, because this material is easy to burn,
