钢筋网与钢筋骨架有什么不同?

添加时间:2019-01-23      发布人:

  1.钢筋网与钢筋骨架的分段(块),应根据结构配筋特点及起重运输能力而定。一般钢筋网的分块面积以6~20m2为宜,钢筋骨架的分段长度宜为6~12m。
  1. Segmentation (blocks) of steel mesh and steel skeleton should be determined according to the structural reinforcement characteristics and lifting capacity. Generally, the area of steel mesh should be 6 ~ 20m2, and the length of steel frame should be 6 ~ 12m.
  2.钢筋网与钢筋骨架,为防止在运输和安装过程中发生歪斜变形,应采取临时加固措施,图9-121是绑扎钢筋网的临时加固情况。
  2. Temporary reinforcement measures should be taken to prevent skewed deion during transportation and installation. Fig. 9-121 is the temporary reinforcement of steel mesh.
  3.钢筋网与钢筋骨架的吊点,应根据其尺寸、重量及刚度而定。宽度大于1m的水平钢筋网宜采用四点起吊;跨度小于6m的钢筋骨架宜采用二点起吊,跨度大、刚度差的钢筋骨架宜采用横吊梁(铁扁担)四点起吊。为了防止吊点处钢筋受力变形,可采取兜底吊或加短钢筋。
  3. The hanging points of steel mesh and steel frame should be determined according to their size, weight and stiffness. Horizontal steel mesh with width greater than 1 m should be lifted by four points; steel skeleton with span less than 6 m should be lifted by two points; steel skeleton with large span and poor stiffness should be lifted by four points of cross hanger beam (iron flat pole). In order to prevent the stress and deion of the steel bar at the hanging point, the bottom hoisting or the shortening of the steel bar can be adopted.
  4.绑扎钢筋网与钢筋骨架的交接处做法,与钢筋的现场绑扎同。
  4. The method of bonding the joint of steel mesh and steel skeleton is the same as that of bonding steel reinforcement on site.

  钢筋焊接网的钢筋标准:产品精度高,误差小,质量好等特点,钢筋网是一种焊接成型的网状钢筋制品,是纵向和横向钢筋分别以一定的间距排列且互成直角,全部交叉点均用强电阻压力熔焊在一起的钢筋网片。钢筋是国家根据社会生产需要而制订出的材料标准,它的屈服强度、极限强度、延伸率、冷弯及可焊性均有很大的不同,不同级别的钢筋使用位置也有很大的不同。一级钢屈服强度235MPa,极限强度310MPa,二级钢屈服强度335MPa,极限强度510MPa,三级钢屈服强度400MPa,极限强度600MPa。所以钢筋网所用的钢筋为三级钢冷轧CRB550材质。现在生产的钢筋焊接网大部分是用于桥面的铺设 大家都知道近几年来桥面的垮塌事故经常性的发生 造成不可估计的财产损失 所以桥面所用的钢筋网固然也很重要 一些小的作坊厂子在做的时候质量不合格 偷梁换柱安装上去留有一定的安全隐患 钢筋网所用的规格尺寸均按国家标准设计 所以钢筋网的质量一定严格按国家标准设计的规格尺寸生产。
  Reinforcement standard of welded reinforcing steel mesh: high precision, small error, good quality and so on. Reinforcing steel mesh is a kind of welded net-shaped reinforcing steel products. It is a reinforcing steel mesh with longitudinal and transverse reinforcing bars arranged at a certain distance and at right angles to each other. All intersections are welded together by strong resistance pressure. Reinforcement bar is a material standard formulated by the state according to the needs of social production. Its yield strength, ultimate strength, elongation, cold bending and weldability are very different, and the use position of different grades of reinforcement bar is also very different. Yield strength of grade I steel is 235 MPa, ultimate strength 310 MPa, yield strength 335 MPa of grade II steel, ultimate strength 510 MPa, yield strength 400 MPa of grade III steel and ultimate strength 600 MPa. So the reinforcing bars used in the reinforcing bar net are CRB550 cold-rolled grade three steel. Now most of the welded steel mesh is used for bridge deck laying. Everyone knows that in recent years, the frequent occurrence of bridge deck collapse accidents has caused inestimable property losses. So the steel mesh used for bridge deck is also very important. Some small workshop factories have unqualified quality to steal beams and replace columns to install steel mesh with certain safety risks. The steel mesh is designed according to the national standard, so the quality of the steel mesh must be strictly produced according to the specifications and sizes designed by the national standard.
