栓钉长度选择需要考虑以下两方面：

1.焊后栓钉高度大于压型钢板波高30MM（注意选择楼板的型号）；

2.栓钉顶面混凝土保护层不小于15MM（注意楼板总厚度）直径不宜大于19MM。

楼承板栓钉型号有ф8、ф10、ф13、ф16、ф19、ф22、ф25，栓钉一般在钢结构建筑中,普遍使用在柱脚和楼板中,一般刚度要求高的柱脚都采用钢柱内伸至混凝土中，钢柱埋入混凝土的部位四周均布栓钉。

楼承板轻钢结构常用厚度为0.8mm,1.0mm，1.2mm,荷载较大的情况下会用到1.5mm。通常需要用栓钉与钢梁连接，板中配少量钢筋，上面浇混凝土层，总厚度约在100-200mm之间。

The length of the studs needs to consider the following two aspects:

1. After welding the height of the bolt is greater than the pressure plate steel wave height 30MM (note the choice of floor model);

2. Pile top concrete protective layer is not less than 15MM (note the total thickness of the floor) diameter should not be greater than 19MM.

Are the general use of steel structures in the column and the floor, the general requirements of the high stiffness of the column are used steel column, the use of steel pillars, Inside the stretch into the concrete, the steel column buried in the concrete parts around the cloth pegs.

Floor board light steel structure commonly used thickness of 0.8mm, 1.0mm, 1.2mm, the larger load will use the case of 1.5mm. Usually need to use the bolt and steel beam connection, the plate with a small amount of steel, pouring concrete layer, the total thickness of about 100-200mm between.
