钢结构檩条用C型钢好还是Z型钢好

来源:/ 日期:2022-10-20 发布人:jiangucaigang
响应环保要求,这几年一直搞钢结构料棚。做钢结构料棚,大部分图纸设计都要考虑用C型钢做檩条。也有人咨询:钢结构檩条用C型钢好还是Z型钢好?下面济南C型钢厂来给您讲讲相关内容。
In response to environmental requirements, steel structure material shed has been established in recent years. As for the construction of steel structure material shed, C-shaped steel shall be considered as purlin in most drawings. Someone also asked: Is it better to use C-shaped steel or Z-shaped steel for steel purlins? Next, Jinan C Steel Plant will tell you something about it.
1、先说一下Z型檩条和的特点。
1. First, let's talk about the characteristics of Z-shaped purlins and.
A、Z型檩条因为弱轴方向的惯性距比同类的C型檁条大,所以它的整休性比C型檩条要好。
A. Since the inertia distance of Z-type purlin in the weak axis direction is larger than that of similar C-type purlin, its integrity is better than that of C-type purlin.
B、因为在连接处要牢固搭接,这样搭接后就成为连续檩条,而C型檩条只能按简支檩条计算。
B. Because the joints shall be firmly lapped, so that they will become continuous purlins after lapping, while C-type purlins can only be calculated as simply supported purlins.
2、现在谈谈檩条的选用问题。
2. Now let's talk about the selection of purlins.
A、一般屋面荷载较大、C型檩条计算困难或算出的结果需选用超大的C型檩条时,考虑用。
A. In general, when the roof load is large, the calculation of C-type purlins is difficult, or the calculated results need to use oversized C-type purlins, consider using.
B、有较大的基本风压的地区,檩条计算此时常常由风吸力控制,此时若用C型檩条计算困难时也可选用Z型檩条。
B. In areas with large basic wind pressure, purlin calculation is often controlled by wind suction at this time. At this time, if it is difficult to calculate with C-type purlin, Z-type purlin can also be selected.
C、建议当屋面板采用暗扣式板而且项目所在地的基本风压较大时,用Z型檩条。因为很多人对暗扣式板和檩条的连接的可靠性表示怀疑,怕在较大的风作用下,暗扣式板会被吸掉,万一出现这种情况,檩条弱轴方向的稳定就成问题了。一般屋面坡度较小时用C型檩条,坡度较大时用Z型檩条,一般屋面坡度在0.10-0.05时用 C型檩条计算就可满足了!
C. It is recommended to use Z-purlins when the roof panel adopts concealed buckle plate and the basic wind pressure of the project site is large. Because many people doubt the reliability of the connection between the concealed buckled plate and the purlin, they are afraid that the concealed buckled plate will be sucked off under the action of strong wind. If this happens, the stability of the weak axis direction of the purlin will become a problem. Generally, C purlins are used when the roof slope is small, Z purlins are used when the slope is large, and C purlins are used when the roof slope is 0.10-0.05!
从受力性能上来说Z型钢要好于C型钢,但为了施工方便,现在墙面及檐口檩条一般还是采用C型钢。所以这个问题就这么讲解完毕了,您对此有什么想法都可以来我们网站提出,互相交流!
In terms of stress performance, Z-shaped steel is better than C-shaped steel, but for the convenience of construction, C-shaped steel is generally used for wall and cornice purlins. So that's the end of this question. You can come to our website if you have any ideas about it Put forward and communicate with each other!
