Xps insulation board and extruded board which is good
The best choice of extruded polystyrene insulation board (extruded board), you said that is called benzene board, much worse than the extruded board, extruded board also qualified to achieve the level, such as B1 level, the market to buy And even the general use of B2 are not reach, especially the cable to produce high temperature, unlike the water to warm. But also to use good, or high temperature certainly toxic
Landing scaffolding to build acceptance records Table 3-6-7 Project name: Engineering unit name: Urban construction company No. Acceptance project erection requirements test results 1 pole base solid level, there are drainage measures. Diverage 5cm thick plank, erected high > 7.55 m, 2 frame and pull knot joint spacing, horizontal, vertical distance to meet the requirements, pull the material meet the requirements, height> 12.6 meters are not allowed to use flexible connection 3 construction layer springboard double springboard banding point of not less than 4 points 4 scissors set not more than 9m set a scissors, angle of 45 ° ~ 60 °, from bottom to top continuous set, the height of more than 24m, in the foot of the corner and the middle along the vertical every 60 ° across the horizontal plane erected Slanting 5 scaffolding material scaffolding fastener steel pipe foot pipe diameter shall not be less than Φ48mm, wall thickness shall not be less than 3.5mm, no serious corrosion, crack, deformation, fastening torque 45 ~ 50N · m6 scaffolding width by design width 1) m erection 7 pole spacing vertical deviation of the vertical bar is not greater than the full length of 1 / 100H, vertical distance between the vertical design (1.8m) m set, deviation ± 50mm8 size horizontal horizontal horizontal vertical.
Insulation materials such as inorganic fiber spraying, glass wool, foam glass, foam ceramic, rock wool, foam cement, closed-cell perlite, etc. . the insulation material is divided into a class of insulation materials: (XPS) / special treatment of polyurethane (PU), phenolic, powder polystyrene particles, etc. . the combustion performance of B2-level insulation materials: the use of non-flammable polystyrene board (XPS) Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE) and so hope can help you!
