栓釘長度選（xuǎn）擇需要考慮以下兩方麵（miàn）：

1.焊後栓釘高度大於（yú）壓（yā）型（xíng）鋼板波高30MM（注意選擇樓板的型號）；

2.栓釘頂麵混凝（níng）土保護層不小（xiǎo）於15MM（注意樓板總厚度）直徑不宜大於19MM。

樓承板栓釘型號有ф8、ф10、ф13、ф16、ф19、ф22、ф25，栓釘（dìng）一般在鋼結構建築中,普遍使用在柱腳和樓板中,一般剛度要求高的柱（zhù）腳都（dōu）采用鋼柱內伸至混凝（níng）土中，鋼柱埋入混凝土的部位四周均布栓（shuān）釘。

樓承板輕鋼結構常用厚度為0.8mm,1.0mm，1.2mm,荷載較大的情況下（xià）會用到1.5mm。通常需要（yào）用栓（shuān）釘與鋼梁（liáng）連接，板中配少量鋼筋，上麵澆混凝土層，總厚度約在100-200mm之間。

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.
