栓釘屬於一種高強度剛度連接的緊固件，用（yòng）於各種鋼結構工程中，在不同連接件中起剛性組合連接作用。用焊接方法把他（tā）固定連接在一個零件(或構（gòu）件)上麵，以便再與其（qí）他零件進行連接.栓釘的規格（gé）為公（gōng）稱直徑10～Ф25mm，焊接前總長度40～300mm。

    Bolts are fasteners with high strength stiffness connections for rigid combination connections in various steel structures. He is attached to a part (or component) by welding so that it can be connected with other parts. The specifications of the stud are nominal diameter 10 ~ Ф25mm, the total length of 40 ~ 300mm before welding.

    在鋼結構中（zhōng），不管是（shì）現（xiàn）澆樓板、普通壓型鋼板還是鋼筋桁架（jià）模板，栓釘是必（bì）須設（shè）置的。由於鋼筋桁架模板（bǎn）兩端有支座豎（shù）向鋼（gāng）筋和鋼梁點焊固定（dìng），所以栓（shuān）釘可采用非穿透焊，而普通的壓型鋼板在鋼梁上的固定需通過栓釘，故必（bì）須采用穿透（tòu）焊（hàn）。穿透焊將影響到壓型鋼板的使用性能及栓釘（dìng）的（de）焊接質量。

    In the steel structure, whether it is cast-in-place floor, ordinary pressure plate or steel truss template, pegs must be set. As the steel bar truss at both ends of the bearing at both ends of the vertical reinforcement and steel beam spot welding fixed, so the tap can be used non-penetrating welding, and ordinary pressure plate in the steel beam on the need to fix the bolt, it must be used to wear Through welding. Penetrating welding will affect the performance of the press plate and the quality of the pegs.

     組合樓板下部為鋼梁（liáng），上部為混凝（níng）土板，兩者共同工作。但是在兩者的（de）結合麵上，也就是（shì）混凝土板底和鋼梁頂麵之間，需（xū）要保證其有效傳（chuán）遞剪力（lì），以（yǐ）免兩者之間相對滑（huá）移。這單靠混（hún）凝土和鋼梁之間的粘結力是遠遠不夠（gòu）的，所以要在鋼梁頂設置栓釘，與鋼梁焊接，並埋入混凝土中（zhōng），這樣就能夠（gòu）有效地傳遞剪力了。

The lower part of the composite floor is steel beam, the upper part of the concrete slab, the two work together. But in the combination of the two, that is, between the concrete floor and the top of the steel beam, you need to ensure that the effective transfer of shear, so as to avoid the relative slip between the two. The adhesion between the concrete and the steel beam is far from enough, so it is necessary to set the pegs on the top of the steel beam and weld with the steel beam and embed it in the concrete so that the shear force can be effectively transmitted.
