1、精軋螺紋鋼的聯結器位置應在粗鋼筋中底部,以免與縱向預應力筋發生碰撞,具體下料長度按照技術交底執行。

1, the bar at the bottom of the coupling position should be reinforced in order to avoid collisions with longitudinal prestressed reinforcement, concrete cutting length according to the technical disclosure execution.

2、鋼筋的聯結器應相互錯開,50cm范圍內聯結器數量不宜大于鋼筋總數的25%。

2, reinforced connector should be staggered, the range of 50cm inline junction should not be greater than 25% of the total number of reinforced.

3、精軋螺紋鋼筋的波紋管內徑為ф50,聯結器位置波紋管內徑為ф80,長度40cm,施工時應保證ф80波紋管與ф50波紋管的連接質量，以免漏漿,兩端用封口膠密封。

3, finishing rolling rebar corrugated tube diameter Phi 50, coupling position corrugated pipe diameter is Phi 80, length 40cm, construction should guarantee the quality of connection of phi 80 Phi 50 corrugated pipe and corrugated pipe, to avoid leakage, ends with sealing glue seal.

4、精軋螺紋鋼宜用砂輪鋸切割下料,嚴禁用電焊或氧氣切割。

4. It is necessary to cut down the blanking with a grinding wheel saw and strictly prohibit the use of electric welding or oxygen cutting.

5、精軋螺紋鋼用連接器連接,接長端需用油漆畫出1/2聯接器長度，以保證被連接鋼筋與聯結器相對位置的準確。

5, the bar with the connector, with the long end with paint to draw 1/2 coupling length, to ensure that the connection of reinforcement and the accurate relative position of coupler.

6、 在搬運、安裝精軋螺紋鋼時,應避免碰傷螺紋,嚴禁點焊精軋螺粗鋼筋;  7、張拉端(即下端)鋼筋外露出螺母的長度為4cm,距梁底為 2.5cm,張拉前鋼筋外露出錨具的長度應大于15cm。

6, when transporting and installing finish rolling thread steel, we should avoid bumping thread, strictly prohibit spot welding, finish rolling screw and coarse steel bar, and 7, the length of the exposed nut on the steel bar of Zhang Laduan (lower end) is 4cm, and the distance from the bottom of the beam is 2.5cm. The length of the anchorage outside the steel bar before stretching should be more than 15cm.

8、豎向預應力筋的孔道中心線與孔道端頭的端面應該垂直，防止精軋螺紋鋼筋受拉受彎折斷.不垂直誤差不應大于±3%。

8, the vertical centerline of the prestressed reinforcement should be perpendicular to the end surface of the end of the hole, so as to prevent the finished rolled bar from being bent and broken. The vertical error should not exceed 3%.
