脚手架指施工现场为工人操作并处置垂直和水平运输而搭设的各种支架。建筑界的通用术语,指建筑工地上用在外墙、内部装修或层高较高无法直接施工的中央。主要为了施工人员上下作业或外围安全网围护及高空安装构件等,说白了就是搭架子,脚手架制造材料通常有:竹、木、钢管或合成材料等。有些工程也用脚手架当模板运用,此外在广告业、市政、交通路桥、矿山等部门也普遍被运用。

Scaffolding refers to various scaffolds for workers to operate and handle vertical and horizontal transportation at construction sites. General terminology in the construction industry refers to the construction site used in the external wall, internal decoration or high-rise can not be directly constructed in the center. Mainly for the construction of workers up and down work or periphery safety net enclosure and high-altitude installation components, it is clear that the scaffolding manufacturing materials are usually: bamboo, wood, steel pipes or synthetic materials. Some projects also use scaffolding as a template, in addition to advertising, municipal, transportation, roads and bridges, mines and other departments are widely used.

不同类型的工程施工选用不同用途的脚手架和模板支架。桥梁支撑架运用碗扣脚手架的居多,也有运用门式脚手架的。主体结构施工落地脚手架运用扣件脚手架的居多,脚手架立杆的纵距普通为1.2~1.8m;横距普通为0.9~1.5m。

Scaffolds and formwork supports are chosen for different types of engineering construction. Most of the scaffolds used in the bridge are bowls and scaffolds. In the construction of main structure, fastener scaffolding is mostly used. The vertical distance of scaffolding vertical bar is generally 1.2-1.8 m, and the horizontal distance is usually 0.9-1.5 M.

脚手架与普通结构相比,其工作条件具有以下特点:

Compared with ordinary structures, scaffolds have the following characteristics:

1、所受荷载变异性较大;

1, the load variation is large.

2、扣件衔接节点属于半刚性,且节点刚性大小与扣件质量、安装质量有关,节点性能 存在较大变异;

2. Fastener joint is semi-rigid, and its rigidity is related to fastener quality and installation quality. The performance of the joint varies greatly.

3、脚手架结构、构件存在初始缺陷,如杆件的初弯曲、锈蚀,搭设尺寸误差、受荷偏心 等均较大;

3. The scaffolding structure and components have initial defects, such as initial bending, corrosion, erection size error, load eccentricity and so on.

4、与墙的衔接点,对脚手架的约束性变异较大。 对以上问题的研讨缺乏系统积聚和统计资料,不具备独立中止概率分析的条件,故对结构抗力乘以小于1的调整系数其值系经过与以往采用的安全系数中止校准确定。因此,本规范采用的设计方法在实质上是属于半概率、半阅历的。脚手架满足本规范规则的构造恳求是设计计算的基本条件。

4, the binding point with the wall has a larger variation on scaffolding. The study of the above problems lacks systematic accumulation and statistical data, and does not have the conditions of independent stopping probability analysis. Therefore, the value of structural resistance multiplied by an adjustment coefficient less than 1 is accurately determined by the stopping calibration of the safety factor previously used. Therefore, the design method adopted in this code is in fact a semi probabilistic and semi empirical one. Scaffolding meets the requirements of the rules and regulations is the basic requirement for design calculation.
