北京做阁楼 搭家庭室内二层钢混楼板施工价格68605253 做钢结构阁楼还是混凝土阁楼房子跨度大,钢结构可以节省一些并少占用空间,还要看你的环境,如果潮湿或防火要求高就不宜于用钢结构,钢结构有抗震、环保和再利用的优点,至于可以用多少年和承受重量这要看你的要求,设计会按业主的要求设计出使用年限和极限荷载。

阁楼制作的工艺材料及方式有很多选择,木质结构,现浇结构,钢结构等。各有优势,其中以钢结构施工快捷,安全稳定,以及很高的性价比,被得到广泛的采纳。钢材与混凝土及木材相比,其屈服点和抗拉伸强度较大,在承载力相同的条件下,钢结构构件截面小,重量轻,便于运输和安装。这些都有利于室内制作结构,同时也会大大的减轻结构因自重对房体本身的负荷。同时钢结构,制造简便,施工周期短,无须保养,后期装饰连接简便。这些优点都有利于楼房结构内的改造与加固。 钢结构阁楼主要以槽钢为主,下面主要讲一下槽钢的搭法阁楼的搭法: 1、槽钢的最关键一点就是槽钢两端的固定。固定方法主要有三种:一种是在墙上用角钢做一个,并用膨胀螺丝锁在墙上,然后用槽钢固定在上面,也可以采用植筋的做法进行固定。此方法只限于两端墙面是承重墙或者刚好有横梁经过的地方,用膨胀螺丝固定于墙上,膨胀螺丝的间隔不超过200mm。另外一种是先在墙上打一个孔,然后把槽钢伸进墙内,并由墙体直接承担槽钢的重量。此方法只限于承重墙或者较厚的剪力墙。另一种方法是直接竖另一条槽钢来支撑横的槽钢,竖的槽钢要固定在墙上。此方法要考虑竖的槽钢所处的位置的楼板的承重能力,宜多点分布式支撑,不要把力集中在少数的槽钢上来承受,第三种做法要求采用槽钢,而不是像第一种做法那样用角钢就行了。一般固定在最长的两边上面,如果最长的两边平行铺设没有固定条件时,也可以与最短的两边进行铺设。
2、解决了槽钢的固定点,下面要解决的就是主龙骨的编排。一般对于居室来说,建议采用120×60×6mm或以上规格的槽钢作用主龙骨。主龙骨应该与最短的一边平行进行铺设,间隔500mm左右。槽钢必须架放在墙上的之上,且与墙面的空隙不超过10mm。槽钢满焊于横档之上。如果与最短的一边平行铺设没有固定条件时,也可以与最长的一边平行进行铺设。
3、再在主龙骨之间焊设副龙骨。副龙骨可采用等边角钢,规格采用5050x4mm或以上的。副龙骨满焊于主龙骨之上,平面一致,并且与主龙骨横向垂直,编排间隔建议值是300mm(最大值),宜密不宜疏。为安全起见,宜在副龙骨与主龙骨之间的下部再焊接一小段角钢的边角料,以策安全。
4、焊接栏杆或者楼梯。栏杆和楼梯只能焊接在主龙骨之上,且必须是满焊。
5、然后用砂纸打磨生锈严重的位置,然后用防锈漆把所有的槽钢和角钢满涂一遍或以上。待其干透后,再涂一层磁漆,磁漆的颜色可以自由选择。
6、在骨架上面铺设15厘的夹板一层,夹板可以用拉钉(铆钉)固定在副龙骨之上。在夹板之上再铺设12厘大芯板(细木工板)一层,两层板之间的板间缝隙位置必须错开,大芯板必须固定在夹板之上,直接打钉就行了。如果不想采用夹板,在副龙骨的密度够密的情况下,在上面铺设一层钢格网之后,甚至可以采用细钢筋加水泥灌浇一层厚度不超过50mm的楼板。采用水泥灌浇的楼板的晃动声要低于用夹板的,但是用水泥灌浇的会有出现一定数量裂缝的可能,这时候必须确保水泥沙浆的配比和混有足够的细钢筋。
7、铺设其他面层材料,例如实木地板,地毯或者瓷砖(限水泥灌浇的楼板)。
