钢筋网的抗裂能力与哪些因素有关?

添加时间:2019-09-16      发布人:

  钢网经过不断的发展和完善,其抗裂性已经有了很大的提高。如果你的钢丝网片抗裂能力下降的现象,需要及时查明具体原因,是否有救援处理点,以下是钢丝网表抗打击的分析问题。
  After continuous development and improvement, the crack resistance of steel mesh has been greatly improved. If the crack resistance of the wire mesh decreases, it is necessary to find out the specific reasons in time and whether there are rescue treatment points. The following is the analysis of the crack resistance of the wire mesh surface.
  钢焊接网在我国的使用还处于起步阶段,我国钢的使用总量不到十分之一的份额。20世纪90年代初,钢焊接网被国家科委、建设部列为重点工程,并制定了规范和规程。
  The use of steel welding net in our country is still in its infancy, and the total amount of steel used in our country is less than one tenth. In the early 1990s, the steel welding net was listed as a key project by the State Science and Technology Commission and the Ministry of Construction, and the regulations and regulations were formulated.
  随着我国基础设施建设的发展,对基础设施建设的贡献不断增加;实施西部大开发战略。经济建设进入新阶段,电力、交通、水利、住宅及市政等基础设施建设对钢焊接网的需求将成倍增长。
  With the development of infrastructure construction in our country, the contribution to infrastructure construction is increasing constantly, and the strategy of western development is implemented. As economic construction enters a new stage, the demand for steel welding network will be doubled in infrastructure construction such as electric power, transportation, water conservancy, housing and municipal administration.

  根据现场开挖情况,施工侧布置的钢网距表面层10 cm,大大超出规范要求,降低了钢网的抗裂能力。由于温度的日益升高、热胀冷缩的影响以及混凝土的特性,表面层的开裂是显著的。
  According to the site excavation, the steel mesh arranged on the construction side is 10 cm apart from the surface, which greatly exceeds the requirements of the code and reduces the crack resistance of the steel mesh. Due to the increasing temperature, the influence of thermal expansion and contraction, and the characteristics of concrete, the cracking of the surface layer is significant.
  铺装层钢网过低,导致混凝土保护层较厚。据报道,铺装层为桥梁结构板上方14cm厚的混凝土路面,为平面路面,为非承重结构。根据规范,铺装层的钢筋网应敷设在面层下方4厘米处。以上这些因素都可能导致钢网片产生裂纹,进而产生脱落。我们只需要注意这些点,然后我们不需要担心太多。
  The steel net of pavement layer is too low, which results in thick concrete protective layer. It is reported that the pavement is a concrete pavement 14cm thick above the bridge structural plate, a plane pavement and a non-load-bearing structure. According to the specifications, the steel mesh of the pavement should be laid 4 centimeters below the surface. All of these factors may lead to cracks in the steel mesh, which may lead to shedding. We just need to pay attention to these points, and then we don't need to worry too much.
