轻质保温防水预制复合板

<正> 轻质保温防水预制复合板(以下简称预制复合板),是以聚乙烯泡沫板与卷材经工厂加工复合而制成的2000mm×1000mm×53mm板块,自1988年由长春市建材化工实验厂首次研制成功和应用后。

预制聚氨酯复合板及其墙体外保温系统

以聚氨酯硬质泡沫塑料(PURF)模塑发泡一步整合成型的方法,预制成具有隔热保温、防水和外饰面层的多功能复合板,作为墙体外保温工程的主体预制构件,采用铺贴墙体面砖的传统工法,用水泥基胶凝材料把预制复合板满粘铺贴上墙,构成隔热保温、防水和外装饰于一体的墙体外保温工程。

外墙外保温用预制聚氨酯复合板研究

介绍了一种外墙外保温用预制聚氨酯复合板的制备工艺、技术性能和施工方法。该复合墙板由聚氨酯硬质泡沫塑料(PURF)与防水结合层和柔性饰面层经模塑发泡一步整合成型,以其作为墙体外保温工程的主体预制构件.采用铺贴墙面砖的传统工艺方法,用掺适量建筑胶的素水泥浆铺贴上墙,可构成集隔热保温、防水和外装饰于一体的墙体外保温工程。

墙体材料未来的主力军——建筑板材

伴随建筑结构大空间、大柱网、大开间灵活隔断的出现,墙体材料的发展趋势将是块状制品向板状制品发展,单一墙体向复合墙体发展,重型墙体向轻型墙体发展.因此,建筑板材越来越受到社会的青睐.国外建筑板材用于墙体材料已占有相当份额,如日本占60%,美国占47%,德国占41%,东南亚国家也达30%以上.

Experimental study on axial compressive behaviors of prefabricated composite thermal insulation walls after single-side fire exposure

The axial bearing capacity of prefabricated composite walls composed of inner and outer concrete wythes,expandable polystyrene(EPS)boards and steel sleeve connectors is investigated.An experimental study on the axial bearing capacity of four prefabricated composite walls after fire treatment is carried out.Two of the prefabricated composite walls are normal-temperature specimens,and the others are treated with fire.The damage modes and crack development are observed,and the axial bearing capacity,lateral deformation of the specimens,and the concrete and reinforcing bar strain are tested.The results show that the ultimate bearing capacity of specimens after a fire is less than that of normal-temperature specimens;when the insulation board thicknesses are 40 mm and 60 mm,the decrease amplitudes are 20.8%and 16.8%,respectively.The maximum lateral deformation of specimens after a fire is greater than that of normal-temperature specimens,and under the same level of load,the lateral deformation increases as the insulation board thickness increases.Moreover,the strain values of the concrete and reinforcing bars of specimens after a fire are greater than those of normal-temperature specimens,and the strain values increase as the thickness of insulation board increases.
