1、精軋螺紋鋼的聯(lián)結(jié)器位置應(yīng)在粗鋼筋中底部,以免與縱向預(yù)應(yīng)力筋發(fā)生碰撞,具體下料長度按照技術(shù)交底執(zhí)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(lián)結(jié)器應(yīng)相互錯開,50cm范圍內(nèi)聯(lián)結(jié)器數(shù)量不宜大于鋼筋總數(shù)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(nèi)徑為ф50,聯(lián)結(jié)器位置波紋管內(nèi)徑為ф80,長度40cm,施工時應(yīng)保證ф80波紋管與ф50波紋管的連接質(zhì)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(yán)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(lián)接器長度，以保證被連接鋼筋與聯(lián)結(jié)器相對位置的準(zhǔn)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(yīng)避免碰傷螺紋,嚴(yán)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(yīng)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(yù)應(yīng)力筋的孔道中心線與孔道端頭的端面應(yīng)該垂直，防止精軋螺紋鋼筋受拉受彎折斷.不垂直誤差不應(yīng)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%.
