Through the roof and wall structure layer tube root, application of the high level of concrete strength grade beans filling is close-grained, tube roots do seal processing, the pipe fixed. Reinforced concrete roof plate base surface dust sundry cut clean and special parts drawing high up, board face level off clean. 6.2.3.5.1.1.3 insulation brick 1, insulation layer should be dry, the moisture content of closed-end insulation should be equivalent to the moisture content of the material in the local natural air-dry condition, and 0.06% or less (volume ratio). Insulation dry with difficulty, exhaust measures should be adopted, can be set up according to the distance between 6 m exhaust slot (groove width 60 mm), no more than 36 m2 set an exhaust hole and exhaust slot should to strengthen layer, leveling layer, find the slope of frame joint, exhaust slot should be set up, and the exhaust steam pipe with large steam connected mutually, this directly with the exhaust steam trough of the exhaust duct level (hutch defends) through. 2, thermal insulation layer with 50 ~ 120 thick polystyrene board, insulation board close to the surface at the grassroots level paving mat, shake not a phenomenon that adjacent joints staggered, plate gap, between surface and the height of the two plates that face. Polystyrene insulation adopts 1:3 cement mortar fixed point sticking method, slurry point distance of 1 m. 3, insulation layer, after the completion of the shop is stuck in the above do fine stone concrete strengthening layer, control of fine stone concrete slump in 50 ~ 70 mm, laid evenly, surface smooth, compaction, and seam lien frame, frame joint area of no more than 36 m2, seam 20 mm wide and leveling layer, find the slope of the corresponding frame joints, joint filling loose material. 4, when the rainy season construction, if encounter insulation construction may be undertaken on a rainy day, is the construction of insulation layer should use plastic sheets to cover, dryi
