The bonding and grinding mechanism of reinforcing bars is anchorage of reinforcing bars. However, due to the contact of the overlapping steel bars, the contact surface lacks enough concrete wrap and a certain grip force. In view of this, after research and practice, the researchers introduced a correction factor greater than 1 times the anchorage length to compensate for the standard application, that is, the length of lap joint. Therefore, lap length = anchorage length * correction factor.

　　我們知道11g101-1的鋼筋搭接需要我們計算，應該說有點麻煩。但是，16g101-1的新版本要簡單得多，直接提供表格，只要一對一的對應就可以。16G101也是常用的結構。

　　We know that the overlap of 11g101-1 steel bar needs our calculation. It should be said that it is a bit troublesome. However, the new version of 16g101-1 is much simpler, providing tables directly, as long as one-to-one correspondence. 16G101 is also the most commonly used structure.

　　表面層鋼筋與鋼框架的焊接或綁扎允許偏差應符合表7.5.4-1的規定。

　　The allowable deviation of welding or binding between surface steel bars and steel frames shall be in accordance with Table 7.5.4-1.

　　表7.5.4-1表面鋼筋與鋼筋框架焊接或綁扎允許偏差(mm

　　Table 7.5.4-1 Allowable deviation (mm) of welding or binding between surface steel bar and steel frame

　　鋼筋焊接搭接長度不小于5d(d為鋼筋直徑)，單面焊接搭接長度不小于10d。鋼筋綁扎搭接長度不應小于35d。

　　The overlap length of steel bar welding is not less than 5 days (d is the diameter of steel bar), and the overlap length of single side welding is not less than 10 days. The overlap length of steel bar should not be less than 35 days.

　　3.同一豎向截面上焊接或綁扎鋼筋的數量不得超過截面鋼筋總數的25%，相鄰鋼筋的焊接或綁扎接縫應錯開500mm或1000mm。縱向連續加固應每隔30米在綁扎處設置一次。點擊這里下載施工技術

　　3. The number of welded or bonded reinforcing bars on the same vertical section shall not exceed 25% of the total number of reinforcing bars on the section. The welded or bonded joints of adjacent reinforcing bars shall be staggered by 500 mm or 1000 mm. Longitudinal continuous reinforcement should be set at the binding site every 30 meters.

　　鋼筋綁扎搭接長度應滿足設計要求，綁扎點應滿足以下要求:

　　The overlap length of steel bar should meet the design requirements, and the binding point should meet the following requirements:

　　1鋼筋搭接時，中間和兩端應搭接三處，必須單獨搭接，再搭接交叉鋼筋;

　　When the reinforcing bars are lapped, three places should be lapped at the middle and two ends, and the cross reinforcing bars must be lapped separately, and then the cross reinforcing bars should be lapped.

　　主筋2根，分布筋2根，變形節處除2 ~ 3根骨架柱外，其余綁扎均可交叉;

　　There are 2 main reinforcements and 2 distributed reinforcements. Except for 2 - 3 skeleton columns at the deformed joints, all the other bonds can be crossed.

　　3主桿之間或雙向受力桿之間的交點應全部綁扎;

　　The intersection points between the main poles or the two-way bearing poles should be all tied up.

　　4. 單腿箍筋與雙腿箍筋的角部應在主腱交點處完全結扎，雙腿箍筋的直部與主腱交點可交叉結扎;

　　4. The corner of single-leg stirrups and double-leg stirrups should be ligated completely at the junction of the main tendon, and the straight part of the double-leg stirrups and the junction of the main tendon can be cross-ligated.

　　5. 墻體、立柱立柱與底板水平主桿的交接點必須綁扎牢固。懸臂梁較長時，交點必須焊好，必要時增加支撐;

　　5. The joints of the wall, column and horizontal main pole of the floor must be firmly tied. When the cantilever beam is long, the intersection must be welded well and support should be added if necessary.

　　除了兩排外，所有的鋼網片的交叉點都是被綁住的。中間部分的交叉口可以相互交錯并牢固結合。

　　Except for two rows, all the intersections of the steel mesh are tied. Intersections in the middle can be crisscrossed and firmly integrated.
