1.1 本指南涵盖了临时围栏施工中使用的各种材料和方法。 1.2 临时围栏是用于定义和指定施工现场边界的物理屏障。 1.3 临时围栏拟在任何施工活动开始前安装，并在施工阶段结束时拆除。服务期限可能会有所不同；应考虑使用临时围栏的时间长度。 1.4 在确定和指定材料和安装方法时，调查合同规范、合同文件、现场平面图围栏位置，以及可能的地方规范。安装前，检查现有现场条件。在某些情况下，应使用永久围栏设施作为临时围栏。 1.5 单位- 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本指南通过安装6英尺或8英尺（1.83米或2.44米）高的临时施工围栏，规定了施工现场临时围栏应用的最低标准要求，用于划定和形成施工现场的物理屏障。只要成品外观整洁、均匀，就可以接受各种各样的新材料和旧材料。 5.2 临时围栏应形成一个连续的屏障，面板式围栏应牢固连接在一起，或用钢配件连接到支柱上，形成正连接。 注1: 关于屏蔽的最终用户警告:应用于围栏的挡风玻璃形成固体屏障。本标准中所述的临时围栏不能处理每ASCE/SEI 7 110 MPH的阵风- 10、如果要安装屏蔽，应研究和设计与永久围栏相同的围栏，以支持风荷载；请参阅链节制造商协会风荷载指南，WLG 2445。 注2: 关于露天挖掘和街角附近安装的终端用户警告。请参阅合同文件、现场平面图或当地规范，了解围栏与开挖的偏移情况，并确保车辆视线清晰，以确保街角安全。

1.1 This guide covers a variety of materials and methods used in the construction of temporary fences. 1.2 Temporary fences are physical barriers used to define and designate the boundary of construction sites. 1.3 Temporary fences are intended to be installed before any construction activity starting and removed at the end of the construction phase. The duration of service can vary; consideration should be given to the length of time the temporary fence will be in use. 1.4 When determining and specifying materials and installation methods, investigate contract specifications, contract documents, site plan fence location, and, possibly, local codes. Before installation, review and inspect existing site conditions. In some cases, a permanent fence installation should be used as temporary fencing. 1.5 Units— The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This guide sets forth the minimum standard requirements for the application of temporary fences for construction sites by installing 6 or 8 ft (1.83 or 2.44 m) high temporary construction fence enclosures used to delineate and form a physical barrier on the construction site. A wide variety of materials, both new and used, are acceptable as long as the finished product is neat and uniform in appearance. 5.2 Temporary fences should form a continuous barrier, panel type fence to be securely attached together or to a supporting post with steel fitting forming a positive connection. Note 1: Warning to end user regarding screening: Wind screens applied to a fence form a solid barrier. The temporary fence described in this standard is not capable of handing 110 MPH wind gusts per ASCE/SEI 7-10. If screening is to be installed the fence should be researched and designed the same as a permanent fence to support the wind load; refer to Chain Link Manufacturers Institute Wind Load Guide, WLG 2445. Note 2: Warning to end user regarding installations adjacent to open excavation and street corners. Refer to contract documents, site plans, or local codes for fence offset from excavations and to ensure vehicles a clear line of sight for street corner safety.
