Wire mesh is also known as wire mesh, steel welding mesh, steel welding mesh, steel welding mesh and wire piece. The longitudinal and transverse reinforcement are arranged at a certain distance and right angle, and all intersections are welded together. Do you know what should be paid attention to before steel mesh welding?
当焊接钢丝网粗糙焊接网不能曲折,焊接1 - 2钢筋焊接网的少,然后两个梁,和直接采用网站绑定方法,弥补减少横向钢筋,附加钢筋焊接网连接的每个节点应选择线绑定。在两个焊接网的两端之间，钢筋搭接处的更小搭接长度不得小于更小锚固长度la的1.3倍。
When the welded steel wire mesh rough welded mesh can not be zigzag, and the last welded 1 - 2 reinforcement welded mesh is less, then two beams, and directly use the website binding method to make up for the reduction of transverse reinforcement, each node connected by the additional reinforcement welded mesh shall be bound by a line. Between both ends of the two welded nets, the minimum lap length of the steel bar lap shall not be less than 1.3 times of the minimum anchorage length la.
When two welded steel meshes in the overlapping area have one non transverse reinforcement, the minimum overlapping length of the welded steel mesh with ribs is 1.3 times of the minimum anchoring length La, and is not 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 for 5 days.
Two methods are selected for the bottom network of welded steel mesh: stud location and pad placement. For the veil of welded steel mesh of two-way bamboo bar, the lap joint of the appropriate method should be set at a relatively small pressure, and the net section should be set from the beam quarter. The lap length should not be less than 30 DD circle direction, and the reinforcement and diameter should not be less than 250 mm.
So, in the welding and laying of steel mesh, we should pay attention to what problems we need to complete today. Before the laying of welded steel mesh, the installation scheme of welded steel mesh shall be proposed first, and the laying of welded steel mesh shall be guided according to the actual situation on site and the field service of equipment professionals, so as to minimize the trouble during the laying of welded steel mesh.
