Z型钢和C型钢的区别有哪些?

一、Z型钢和C型钢的角度不一样,C型钢成90度而Z型钢小于90度,所以一定坡度的屋面采用檩条时就要结合受力知识考虑檩条的角度问题,坡度大采用Z型钢可以充分利用其的抗弯性能。
1、 The angle of Z-section steel is different from that of C-section steel. C-section steel is 90 degrees and Z-section steel is less than 90 degrees. Therefore, when purlins are used for roofs with a certain slope, the angle of purlins should be considered in combination with stress knowledge. The use of Z-section steel with a large slope can make full use of its bending performance.

二、C型钢截面与Z型钢截面相比,强弱轴的力学性能差异较大,且与钢架的连接多为螺栓铰接,计算时须按简支考虑.故从受力状态,构造以及计算结果等角度看,后者更合理一些.所以除门窗洞口以及其它特殊节点处理需要外,应优先选用Z型钢截面。

2、 Compared with the Z-shaped steel section, the mechanical properties of the strong and weak axes of the C-shaped steel section are quite different, and the connection with the steel frame is mostly hinged by bolts, which must be considered as simple support in calculation. Therefore, the latter is more reasonable from the point of view of stress state, structure and calculation results. Therefore, in addition to the treatment needs of door and window openings and other special joints, the Z-shaped steel section should be preferred.

三、在屋面坡度较小时,Z型钢檩条抗弯截面模量稍大于C型钢檩条,但差别不大,当屋面坡度增大,Z型檩条对称于竖直方向的抗弯截面模量利用率增大.所以Z型檩条适用于坡度较大的屋面。
3、 When the roof slope is small, the bending section modulus of Z-shaped steel purlin is slightly larger than that of C-shaped steel purlin, but the difference is small. When the roof slope increases, the utilization rate of bending section modulus symmetrical to the vertical direction of Z-shaped purlin increases. Therefore, Z-shaped purlin is suitable for roofs with large slope.

四、对于墙面,选择Z型钢或者C型钢没有多大区别,如果檩条想做成连续构件,最好Z型檩条,因其搭接方便。
4、 For the wall, there is no big difference between selecting Z-shaped steel or C-shaped steel. If the purlin wants to be made into a continuous member, it is best to use Z-shaped purlin because it is easy to overlap.
