钢筋垫块机功能
钢筋垫块机功能
Function of reinforcement block machine
建筑材料中，垫块机的应用是很广泛的。在建筑过程中，水泥垫块可以作为其他物品特别是钢筋的保护层，所以水泥垫块的质量一定要可靠。下面我们介绍一些水泥垫块在建筑行业中的作用:
In building materials, the application of block machine is very extensive. In the construction process, the cement cushion block can be used as the protective layer of other items, especially the reinforcement, so the quality of the cement cushion block must be reliable. Here we introduce the role of some cement blocks in the construction industry:
1、承受外力作用 保护层对钢筋有锚固力,利用混凝土与钢筋间的锚固力,两者紧密结合,共同参与工作.保护层过薄或缺失时,减低了它的锚固力从而降低了结构抵抗轴力和弯矩的作用.
1. Under the action of external force, the protective layer has the anchoring force to the steel bar. The anchoring force between the concrete and the steel bar is closely combined to participate in the work together. When the protective layer is too thin or missing, its anchoring force is reduced, so as to reduce the role of the structure against axial force and bending moment
2、防火保护层混凝土具有一定的隔热作用,遇到火灾时能对较易软化的钢筋进行保护,如果保护层厚度过薄,在高温环境下容易开裂,致使钢筋因过热而降低强度从而破坏整体结构.2003年湖南衡阳某工程就因大火燃烧产生的高温高热使钢筋软化导致坍塌并造成重大伤亡事故.
2. The concrete of fire protection layer has certain heat insulation function, which can protect the steel bars that are easy to soften in case of fire. If the thickness of the protection layer is too thin, it is easy to crack under high temperature environment, which causes the steel bars to reduce the strength due to overheating, thus damaging the overall structure. In 2003, a project in Hengyang, Hunan Province, softened the steel bars due to the high temperature and high heat caused by fire combustion, resulting in collapse and major casualties So
3、维护结构耐久性混凝土中保护层太薄容易渗入潮湿气体和水,过厚则易产生裂缝,这些都可能使钢筋锈蚀并膨胀,从而使混凝土遭受破坏,影响使用和结构安全.
3. The protective layer in the durability concrete of maintenance structure is too thin and easy to penetrate into the moist gas and water. If it is too thick, it is easy to produce cracks. All of these may cause corrosion and expansion of steel bars, thus causing damage to the concrete, affecting the use and structural safety
4、从正截面受弯承载力计算公式可以看出,当面筋保护层过厚导致截面有效高度h0减小时,将降低截面受弯承载力.可见保护层厚度是影响结构承载力多么重要的因素. 主要生产各种水泥垫块，塑料垫块，铁垫块、主要用于楼房现浇，公路铁路、桥梁及古建筑，钢筋混凝土保护层垫块、横梁支撑、钢筋层间距标准垫块支撑等。 水泥钢筋保护层垫块的质量，直接关系到钢筋在混泥土工程结构中的承载力.耐久性.耐酸碱.防火等状况.
4. It can be seen from the calculation formula of flexural bearing capacity of normal section that when the effective height H0 of the section is reduced due to the thickness of the protective layer of the gluten, the flexural bearing capacity of the section will be reduced. It can be seen that the thickness of the protective layer is how important the bearing capacity of the structure is. It mainly produces various cement cushion blocks, plastic cushion blocks, iron cushion blocks, which are mainly used for cast-in-place buildings, highways, railways, bridges and ancient buildings, reinforced concrete Cushion block of concrete protective layer, beam support, standard cushion block support of reinforcement layer spacing, etc. The quality of the cushion block of cement reinforced protective layer is directly related to the bearing capacity, durability, acid and alkali resistance, fire protection and other conditions of the reinforcement in the concrete engineering structure
