The construction of g, sound absorption wall body structure and sound absorption ceiling structure；
The installation of h, door and window：
Doorframe is welding with embedded board connected mode, and the size and flatness of doorframe should be checked before welding；During welding, solder joint should be satisfied
It is full, and brushing antirust paint, doorframe and the micro-expansion cement mortar perfusion of body of wall gap, door pocket is done using core-board before perfusion,
Doorframe is protected, when doorframe is in the milk, bamboo slab rubber formwork is first used, then 500mm is one section, packer grouting, it is to avoid occurred
Hollowing phenomenon；
Check window hole installation dimension, the position not being inconsistent to size carries out picking chisel or repairing treatment, window hole surrounding sound-proof wall with
Cavity between structural wall arranges the wide additional light joist partition walls of 350mm, pre- between additional light joist partition wall and sound-proof wall
50mm spaces, surrounding is stayed to fill out the thick rock wools of 50mm, width 300mm and 50mm thick rubber blanket is corresponding along the laying of window hole surrounding
The core-board of the number of plies, core-board length to should be parallel with glass installation direction,
, it is ensured that glass surrounding completely fills out glass cement when sound control glass is installed.
10. in a kind of room as claimed in claim 9 atrial septum sound shock mitigation system construction method, it is characterised in that：Described
In (b), (C) construction procedure in the construction of sound insulation vibration damper floor, bottom sound insulation buffer layer and base concrete flaggy can be provided with
Construction；
Bottom sound insulation buffer layer is the sound insulating material pipe being arranged side by side；Or be the sound insulating material pipe arranged in spacing distance；Or be
In spacing distance arrange sound insulating material pipe and in spacing distance arrange sound insulating material pipe between fill out set foam sound insulation material
Material；
Base concrete flaggy is set in the upper end of bottom sound insulation buffer layer, base concrete flaggy is precast rc slab, and bottom is mixed
