1, the lightweight steel design theory of computation is comparatively perfect, but the problem of structure and energy saving integrated does not have fine solution; Lack the heat insulating material of the suitable for China of suiting measures to local conditions;
2, difficulty of construction strengthens, and needs professional contingent;
3, design research and development are combined with market not, and engineering application is limited to pilot more;
4, lightweight steel construction system is served urban villa class building more at present, and overall cost is higher, is difficult to be suitable for for vast village-town house;
5, foam cement or glass bead, can improve insulation, the acoustical effectiveness of building as the insulation layer of body of wall, it is effective that thermal insulation reduces energy consumption, but in light-weight structure residence, not yet apply, universal, in light-weight structure residence, lack complete embodiment.
