    钢框架结构和混凝土结构的对比!
    来源:http://www.wasolo.com  2019-06-18 11:23:41
    钢结构具有结构重量轻、抗震性能好、工业生产水平高、施工速度快、建筑造型美观、环保、空间大等优点。建设部称其为可重复使用的环保绿色建筑。在砂石资源日益紧张的今天,钢结构的优势越来越明显。
    Steel structure has the advantages of light weight, good seismic performance, high level of industrial production, fast construction speed, beautiful building shape, environmental protection and large space. The Ministry of Construction calls it an environmentally friendly and reusable building. In today's increasingly tense sandstone resources, the advantages of steel structure are becoming more and more obvious.
    一、钢框架结构与普通钢混凝土结构相比的优点
    I. Advantages of Steel Frame Structures over Ordinary Steel Concrete Structures
    1. 钢框架结构采用钢混凝土柱+钢梁结构。由于明显高于混凝土强度,钢结构强度大大减少框架柱和梁截面,使混凝土和钢铁消费大大减少,主要的是大大减少了体重的结构,根据体重(柱和梁)大约可以减少约30%,从而大大减少压力的基础上,减少土壤基础施工开挖的体积,小而破坏的土地资源可以显著降低地基成本(在高层建筑中,占整个建筑成本的三分之一)。
    1. Steel frame structure adopts steel concrete column + steel beam structure. Because the strength of steel structure is obviously higher than that of concrete, the cross-section of frame columns and beams is greatly reduced, and the consumption of concrete and steel is greatly reduced. The most important thing is the structure which greatly reduces the weight. According to the weight of columns and beams, it can be reduced by about 30%. On the basis of greatly reducing the pressure, the volume of excavation of soil foundation construction is reduced. Small and destructive land resources can significantly reduce the foundation composition. Ben (in high-rise buildings, accounts for one third of the total construction cost).
    2. 钢混凝土柱提高了框架柱的承载力,减小了柱的钢板厚度,增加了柱的刚度以及相应的结构侧移刚度,有利于提高柱的防火能力。
    2. Steel reinforced concrete columns improve the bearing capacity of frame columns, reduce the thickness of steel plates, increase the stiffness of columns and the corresponding lateral stiffness of structures, which is conducive to improving the fire resistance of columns.
    3.钢结构的强度明显高于混凝土结构,使其更容易获得较大的空间,提高了室内空间的利用率。在以前空间较大的建筑中,内部有较大截面的混凝土柱,影响了外观和使用。部分地区的主要组成部分的钢结构小于钢筋混凝土结构(列部分是1/6和梁高度为150 ~ 200小根据这个项目的初步框架计算),使所有者获得更大的可用面积相同的情况下。一般可扩大使用面积5%-10%。
    3. The strength of steel structure is obviously higher than that of concrete structure, which makes it easier to obtain larger space and improves the utilization ratio of indoor space. In previous buildings with larger space, concrete columns with larger cross-section in the interior affect the appearance and use. In some areas, the main components of the steel structure are smaller than the reinforced concrete structure (column is 1/6 and beam height is 150-200 according to the preliminary frame calculation of this project), so that the owner can obtain larger available area under the same circumstances. Generally, the area of use can be expanded by 5%-10%.

    4、钢结构施工速度快,综合考虑制造周期、安装周期、材料成本、管理费等因素,成本长时间对项目具有经济优势。
    4. The construction speed of steel structure is fast. Considering the factors of manufacturing cycle, installation cycle, material cost and management fee, the long-term cost has economic advantages for the project.
    5. 由于钢结构零件在厂内生产规模大,加工精度高,有利于现场施工精度控制,其误差控制采用“毫米”控制;混凝土施工精度是“厘米”控制的。
    5. Because of the large scale of production and high processing accuracy of steel structural parts in the factory, it is beneficial to the accuracy control of field construction. Its error control adopts "millimeter" control; concrete construction accuracy is "centimeter" control.
    6、钢结构施工可干燥、节水、施工面积小,生产噪音、扬尘小,且建筑物外观可轻易满足多样化的要求,有利于外墙的装饰。
    6. Steel structure construction can be dry, water-saving, small construction area, low noise and dust, and the appearance of buildings can easily meet the requirements of diversification, which is conducive to the decoration of external walls.
    7、钢结构的使用可以大大减少混凝土和砖瓦的使用,有利于环保是当前建筑发展的趋势。
    7. The use of steel structure can greatly reduce the use of concrete and bricks, which is conducive to environmental protection is the current trend of building development.
    8. 建筑使用寿命期满后,拆除钢结构产生的固体废物较少,废钢资源的回收价格较高。目前钢结构建筑是对城市环境影响小的结构之一,因此被称为绿色建筑,也是当年国家重点扶持和发展的对象。
    8. After the service life of the building has expired, the solid waste produced by demolishing the steel structure is less, and the recovery price of the scrap steel resources is higher. At present, steel structure building is one of the structures with the smallest environmental impact on the city, so it is called green building, and it is also the object of national key support and development in that year.
    9,易于使用的钢框架结构的地板使用钢筋桁架LouCheng板和混凝土组合楼板,钢桁架信使的板楼,选择正确的类型的信使地板,倒在3 m跨层不支持,从而大大减少了剂量的铸造板使用脚手架、模板、和人工成本,大量的措施,以降低工程造价,降低工程造价,加快施工速度,可根据工程要求节省脚手架和模板约40% - 50%。
    9. The floor of easy-to-use steel frame structure is composed of steel truss LouCheng slab and concrete slab, steel truss messenger slab, and the right type of messenger floor is selected, which is not supported by 3 m span floor. As a result, the amount of scaffolding, formwork and manual cost of cast slab is greatly reduced. A lot of measures are taken to reduce the cost of construction, reduce the cost of construction and accelerate the construction speed. Scaffolding and formwork should be saved about 40% - 50% in engineering.
    二世。钢框架结构与普通钢混凝土结构相比的缺点:
    King II. Defects of steel frame structure compared with ordinary steel concrete structure:
    从现有的钢结构建筑来看,钢结构的主要缺点是腐蚀和防火两个方面,
    From the point of view of existing steel structure buildings, the main shortcomings of steel structure are corrosion and fire protection.
    钢结构在发生火灾时防火性能较差,需要用油漆刷或混凝土包上防火涂料。
    In case of fire, the fire resistance of steel structure is poor, so it is necessary to coat it with paint brush or concrete.
    2. 在生产和施工过程中,应注意除锈防锈。
    2. In the process of production and construction, attention should be paid to rust removal and rust prevention.
    3.变形比混凝土框架结构大,但在多层结构中变形不明显。
    3. Deformation is larger than that of concrete frame structure, but it is not obvious in multi-storey structure.
    4. 钢结构暴露时,会出现特殊的冷桥问题,需要通过设计来解决。
    4. When steel structure is exposed, there will be special cold bridge problems, which need to be solved by design.
    5. 超高层建筑具有明显的经济性,但多层常规结构的造价往往较高。
    5. Super high-rise buildings have obvious economy, but the cost of multi-storey conventional structures is often higher.
