钢筋是指钢筋混凝土和预应力钢筋混凝土中使用的钢，其截面为圆形，有时为四角正方形。包括圆杆、肋杆、扭杆。塑假山中常用的钢筋是6.5根轻圆钢条，钢是塑假山内部焊接的基础，具有增加产品形状稳定性、增加抗拉强度、抗剪强度、抗弯强度、抗压强度、减少变形、抗拉率等特点。钢与主要钢结构焊接支撑在塑料假山石、固定钢丝网和水泥砂浆中，也能起到塑造山体形状的作用。
Reinforcement refers to the steel used in reinforced concrete and pre-stressed reinforced concrete. Its section is round, sometimes quadrangular. It includes round rod, rib rod and torsion rod. The commonly used reinforcing bars in plastic rockery are 6.5 light circular steel bars. Steel is the basis of internal welding of plastic rockery. It has the characteristics of increasing shape stability, increasing tensile strength, shear strength, flexural strength, compressive strength, reducing deformation and tensile rate. Welding support of steel and main steel structures in plastic rockery, fixed wire mesh and cement mortar can also play a role in shaping the shape of mountains.
塑料假山在钢铁中的作用，供您详细说明:
The role of plastic rockery in iron and steel can be explained in detail for you.
1. 增强强度和韧性。由于钢筋的硬度比较高，水泥砂浆附着在钢筋上，可以塑石假山硬度高。
1. Strengthen strength and toughness. Because of the high hardness of steel bars, cement mortar adheres to steel bars, which can produce high hardness of plastic rockery.
2. 塑造。塑石假山的整体造型主要靠钢焊接来塑造，凹凸和山的造型靠钢的高度来支撑，同时延长塑石假山整体的使用寿命。
2. Shaping. The overall shape of plastic rockery is mainly shaped by steel welding, while the shape of concave and convex rockery is supported by the height of steel, and the overall service life of plastic rockery rockery is prolonged.
3.降低成本。在钢结构的支撑下，塑石假山表面的砂浆层可以适当的薄，大大降低了成本。
3. Cost reduction. Supported by steel structure, the mortar layer on the surface of plastic rockery can be appropriately thin, which greatly reduces the cost.
4、降低收缩系数，塑山假山在温度的影响下会产生一定的膨胀系数，使钢筋的收缩系数降低细度，可以大大降低水泥砂浆的膨胀收缩系数，保持结构的稳定性。
4. Reducing the shrinkage coefficient will produce a certain expansion coefficient under the influence of temperature, which will reduce the fineness of steel bar, greatly reduce the expansion and shrinkage coefficient of cement mortar, and maintain the stability of the structure.
钢筋在市场分为高线和通用线,要注意材料的选择,钢丝是完全符合规定的合格产品,使用钢丝钢可以确保项目的质量在很大程度上。
Reinforcement bar in the market is divided into high-speed line and general line. Material selection should be paid attention to. Steel wire is a qualified product that fully conforms to the national regulations. Using steel wire can ensure the quality of the project to a large extent.
