Anti-cracking artificial ice rink ice layer
The utility model discloses an anti-cracking artificial ice rink ice layer, and belongs to the technical field of structural engineering. The problem that an ice layer of an existing artificial ice rink is prone to cracking is solved. The ice layer is composed of a carbon fiber net layer, a refrigerating layer, a carbon fiber net ice layer and an upper ice layer from bottom to top. The carbon fiber net and the ice layer are integrally stressed, the carbon fiber bears tensile stress, and the ice layer mainly bears compressive stress, so the problems that the tensile strength of the ice layer is far smaller than the compressive strength, so that the ice layer is easy to bend and crack and low in bearing capacity are solved. In addition, compared with reinforcing materials such as a steel wire mesh and reinforcing steel bars, the carbon fiber mesh is higher in strength and elasticity modulus and bears larger tensile stress; the thermal expansion coefficient is small, the self change is insensitive to the temperature change, and the additional stress generated on the ice layer under the action of a non-uniform temperature field is small. The ice layer is simple in structure, convenient to construct, effective and practical, can be applied to artificial ice layer construction, and has wide application prospects. The method is suitable for ice layer cracking resistance of the artificial ice rink.
一种抗开裂的人工冰场冰层，它属于结构工程技术领域。它要解决现有人工冰场的冰层容易开裂的问题。冰层：自下而上由碳纤维网层、制冷层、碳纤维网冰层和上部冰层组成。本发明中所用碳纤维网和冰层整体受力，其中碳纤维承受拉应力，冰层主要承受压应力，从而解决冰层抗拉强度远小于抗压强度的特性造成的易弯曲开裂和承载力低问题。另外，相比钢丝网、钢筋等加强材料，碳纤维网强度和弹性模量更高，承受的拉应力更大；热膨胀系数小，其自身变化对温度变化不敏感，其在不均匀温度场作用下对冰层产生的附加应力小。本发明中冰层构造简单、施工方便且有效实用，可应用到人工冰层建造中，具有广泛的应用前景。本发明适用于人工冰场的冰层抗开裂。
