本专利提出一种建筑用墙板,它可用作外墙材料。其特点是在岩棉毡的一侧复合掺有纤维的碳酸钙水泥板,另一侧复合镀锌薄钢板。这种墙板绝热性、耐热性、隔声性及抗冲击性都极好,而且重量轻、使用性能好。该建筑用墙板如图所示。图中1为岩棉毡;2为掺有纤维的碳酸钙水泥板;3为镀锌薄钢板;5为槽钢;4为由槽钢构成的钢框,该钢框配置在2和3之间,将岩棉毡1的周围包起来;掺有纤维的碳酸钙水泥板2通过螺钉6固定在钢框4上;镀锌薄钢板则通过例如粘接等方法加以固定。该建筑用墙板经JIS A 1302规定的室外防火2级试验证实,该板绝热性和防火性都很好,完全合格,而且重量轻,使用方便。用作外墙板时,各材料的厚度为:掺有纤维的碳酸钙水泥板2为8mm;岩棉毡1
This patent proposes a building wallboard that can be used as an exterior wall material. It is characterized by the composite of calcium carbonate cement boards with fiber on one side of the rock wool blanket and the composite galvanized steel sheet on the other side. This kind of wallboard is excellent in heat insulation, heat resistance, sound insulation and impact resistance, light weight, and good performance. The building wall panel is shown in the picture. 1 is a rock wool blanket; 2 is a calcium carbonate cement board with fiber; 3 is a galvanized steel sheet; 5 is a channel steel; 4 is a steel frame composed of channel steel, and the steel frame is arranged in 2 and 3 The surrounding of the rock wool blanket 1 is wrapped; the calcium carbonate cement board 2 doped with fibers is fixed to the steel frame 4 by screws 6; and the galvanized steel sheet is fixed by, for example, adhesion. The outdoor fireproof Class 2 test specified by JIS A 1302 for the building wallboard has confirmed that the board is very good in heat insulation and fire resistance, fully qualified, light in weight, and easy to use. When used as an exterior wall panel, the thickness of each material is: the calcium carbonate cement board 2 with fiber is 8mm; rock wool blanket 1
