之间的两块焊接网、较小的钢筋搭接长度不应小于1.3倍较小的锚固长度,和不应小于200毫米的搭接区,每个焊接网片横向钢筋不应小于1,两个钢丝网片的横向钢筋间距不应小于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.
搭接区域有一个无横向钢筋的钢网片时,加筋钢网片的较小搭接长度应是较小锚固长度la的1.3倍,且不应小于300mm。当搭接区域纵向受力钢筋直径d≥10mm时,搭接长度应增加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.
今后钢网设备的检验方法:钢网铺装的主要工序是:钢网焊接后应按设计图纸定位——网片设备——网片检验。补强钢网的一级配筋是:设备底网-附加垫网或补强设备-承重面网铺-水平和水平面网铺-附加网和补强设备。
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.
在网架的底部,左右要注意主筋应放在挡块的底部,当网架的主筋左右放在挡块的顶部。当两个相邻的网格存在重叠时,在重叠区域的和两端应选择钢丝绑扎牢固,绑扎点不小于3。附加的钢筋和焊接网的每个接头都由铁丝绑扎而成。
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.
