Oblique microlith coagulation upper layer, transverse direction, Vertical Cracks occur for wall side, have influence on the durability and practical usability of floating build floor
Energy.
China's modern wood structure has progressively gone on the road of industrialization from the later stage nineties, by the development of nearly 30 years,
Just has certain scale, market constantly expands.Although timber structure has the synthesis excellent properties of good green energy conservation, wooden building
Cover affected by vibration larger under normal operating condition, constrain further genralrlization and the use of timber structure to a certain extent.Such as
Where not excessively change scantling in the case of, improve development of the wooden superstructure damping property for China's timber structure have it is important
Meaning.
