之間的兩塊焊接網、較小的鋼筋搭接長度不應小于1.3倍較小的錨固長度,和不應小于200毫米的搭接區(qū),每個焊接網片橫向鋼筋不應小于1,兩個鋼絲網片的橫向鋼筋間距不應小于50毫米。
The overlapping length of the last two welded meshes and the smaller reinforcement shall not be less than 1.3 times of the smaller anchoring length, and the overlapping area shall not be less than 200 mm. The transverse reinforcement of each welded mesh shall not be less than 1, and the spacing between the transverse reinforcement of the two steel mesh shall not be less than 50 mm.
搭接區(qū)域有一個無橫向鋼筋的鋼網片時,加筋鋼網片的較小搭接長度應是較小錨固長度la的1.3倍,且不應小于300mm。當搭接區(qū)域縱向受力鋼筋直徑d≥10mm時,搭接長度應增加5d。
When there is a steel mesh without transverse reinforcement in the overlapping area, the smaller overlapping length of the reinforced steel mesh shall be 1.3 times of the smaller anchoring length La, and shall not be less than 300 mm. When the diameter of the longitudinal stressed reinforcement in the overlapping area D ≥ 10 mm, the overlapping length shall be increased by 5 days.
今后鋼網設備的檢驗方法:鋼網鋪裝的主要工序是:鋼網焊接后應按設計圖紙定位——網片設備——網片檢驗。補強鋼網的一級配筋是:設備底網-附加墊網或補強設備-承重面網鋪-水平和水平面網鋪-附加網和補強設備。
Inspection method of steel mesh equipment in the future: the main process of steel mesh pavement is: after the steel mesh is welded, it should be positioned according to the design drawings - mesh equipment - mesh inspection. One grading reinforcement of steel mesh reinforcement is: equipment bottom net - Additional mat net or reinforcement equipment - bearing surface net - horizontal and horizontal surface net - additional net and reinforcement equipment.
在網架的底部,左右要注意主筋應放在擋塊的底部,當網架的主筋左右放在擋塊的頂部。當兩個相鄰的網格存在重疊時,在重疊區(qū)域的和兩端應選擇鋼絲綁扎牢固,綁扎點不小于3。附加的鋼筋和焊接網的每個接頭都由鐵絲綁扎而成。
At the bottom of the grid, the left and right main reinforcements should be placed at the bottom of the block, when the main reinforcements of the grid are placed at the top of the block. When there is overlap between two adjacent grids, steel wire shall be selected at the center and both ends of the overlapping area to bind firmly, and the binding point shall not be less than 3. Each joint of additional reinforcement and welded mesh is bound by iron wire.
