在铺设钢筋网前,应制定钢筋网的布置图。钢网敷设时,应根据现场实际需要放置在现场。当钢网较薄时,可采用钢网的z形变形函数。,将网格的中间部分扭曲,使两端都能刺入梁中,然后铺上网格。
Before laying the reinforcing steel mesh, the layout plan of reinforcing steel mesh should be drawn up. When laying the steel mesh, it should be placed on the spot according to the actual needs of the site. When the steel mesh is thin, the Z deformation function of the steel mesh can be used. First, the middle part of the grid is twisted so that both ends can be pierced into the beam, and then the grid is laid.
当钢筋网无法弯曲时,焊接网端可焊接1-2根钢筋,然后将两个头插入梁内,采用直杆法,采用现场组合法。在切割单杠、钢筋和焊接网的连接处,应选择钢丝绳的连接方式。设置和填充底部网格有两种方法。双向钢筋的面层网络应采用平面搭接接头进行选择。应设置较低的力,应设置在梁边四分之一跨度处,圆的长度不小于30dd,钢筋直径不小于2.5m。
When the reinforcing bar net can not bend, 1-2 reinforcing bars can be welded at the end of the welding net, and then the two ends are inserted into the beam, using the straight bar method and the field combination method. In the connection of cutting horizontal bar, steel bar and welding net, the connection mode of steel wire rope should be selected. There are two ways to set and fill the bottom grid. The surface network of bidirectional reinforcing bar should be selected by plane lap joint. Lower forces should be set at the quarter span of the girder edge. The length of the circle should be no less than 30dd and the diameter of the reinforcing bar should be no less than 2.5m.
的小钢筋搭接接头的搭接长度不应小于1.3倍的小锚固长度之间的后两个焊接接头,它不应该少于200的区域,和每个酒吧电焊网之间的距离不得小于1,和酒吧两网之间的距离应不小于50。筋网的小搭接长度应是小锚固长度的1.3倍,且不应小于300,搭接带是两种钢织物中无横向钢筋的一种。
The lap length of the minimum steel bar lap joint should not be less than 1.3 times of the minimum anchorage length between the last two welded joints, it should not be less than 200 areas, and the distance between each bar welding network and bar welding network should not be less than 1, and the distance between the two bars should not be less than 50. The minimum lap length of the web should be 1.3 times of the minimum anchorage length and should not be less than 300. The lap band is one of the two kinds of steel fabrics without transverse reinforcement.
钢筋网铺装的主要工艺是:焊接钢筋网应按设计图纸进行定位-筛检。一阶钢网是设备的底网—附加缓冲网或钢筋—支撑面网敷设—垂直和水平面网敷设—附加网和钢筋。铺底网时,主应力钢筋应位于网孔下方。铺好地网后,主要钢筋应在网孔上方。
The main technology of steel mesh pavement is: welding steel mesh should be positioned and screened according to the design drawings. The first-order steel mesh is the bottom mesh of equipment - additional buffer mesh or steel bar - support surface mesh laying - vertical and horizontal mesh laying - Additional mesh and steel bar. When laying the bottom mesh, the main stress steel bar should be located below the mesh hole. After laying the net, the main reinforcement bar should be above the net hole.
