发布时间:2015-9-7 9:17:13 浏览次数:499



墙体结构

承重墙由立柱、顶导梁和底导梁、支撑、墙体结构面板组成。立柱为C形轻钢构件,其壁厚根据所受的荷载而定,通常为075~2mm,立柱间距一般为400~600mm,立柱的下端为开口朝上的底导梁,立柱上端为开口向下的顶导梁;为提高墙柱的稳定性,一般墙柱高度范围内设1~2道水平钢拉条或撑杆。这种墙体结构布置方式,可有效承受并可靠传递竖向荷载,且布置方便。为抵抗水平风荷载与地震作用,轻钢结构住宅体系中抗侧力体系、抗剪墙可采用墙体结构面板、交叉支撑或K型支撑形式。用作抗剪墙的结构面板可采用定向刨花板、石膏板、水泥纤维板及薄钢板。上下楼层之间通过连接件可靠连接,以有效传递水平剪力与和上拔力。

屋面结构

屋面结构采用轻钢桁架的方式作为屋面的主要承重结构。屋面桁架的间距根据屋面荷载的不同可以按照300~1200mm布置。屋面桁架上部可以用轻型的檩条,檩条跨度最大可以做到1800mm。屋面的围护可以根据客户的需求采用传统的水泥瓦、陶瓦,或者是时尚的多彩沥青瓦或颜色丰富的金属屋面板。由于整个屋面系统都是空间桁架,整个屋面的保温隔热都可以集成到斜屋面和平吊顶两部分,中间的空间可以通风,让整个建筑更加透气,成为可以呼吸的房屋。


The wall structure

Main wall by columns, guide beam top and bottom of guide beam, support, the structure of the wall panel. Column for c-shaped steel members, according to the wall thickness of load, usually 075 ~ 2 mm, column spacing generally is 400 ~ 600 mm, the lower end of the column to open up the bottom of the guide beam, the column top is open to the bottom top guide beam; In order to improve the stability of the wall column, general wall column height will be 1 ~ 2 level steel brace or poles. This kind of wall body structure arrangement, can effective and reliable delivery under vertical load, and the arrangement is convenient. To resist horizontal wind load and earthquake action, light steel structure housing system in the system to resist lateral force, shear wall can use wall panel structure and cross support or K type support form. Used as the structure of shear wall panel can use directional particieboard, gypsum, cement fiberboard and thin plate. By fitting a reliable connection between upper and lower floors, in order to effectively transfer horizontal shear force and pulling force.

Roof structure

Using light steel roofing structure as the main bearing structure of roof truss. According to different roof load of roof truss spacing can be according to the 300 ~ 1200 mm. The upper roof truss can use lightweight purline, purlin biggest span can do 1800 mm. Roof enclosure can according to customer demand the traditional cement tile, ceramic tile, or is fashionable and colorful asphalt shingle or colorful metal roofing board. Because the whole roof system is space truss, the whole roof heat preservation and heat insulation of peace can be integrated into inclined roofing condole top two parts, in the middle of the space can be ventilated, make the whole building more breathable, the house of the be able to breathe.
