1.1 本指南涵盖了现浇混凝土施工中止水带的使用。止水带通常放置在混凝土中静态的、不移动的施工接缝内，以将接缝与水封闭，水可能处于显著的静水压力下。它们被用作建筑物或其他结构整体防水策略的一部分。伸缩接头和其他类型的移动接头可能需要使用止水带，止水带可以适应结构的预期移动，超出了本指南的范围。 1.2 以SI单位或英寸-磅单位表示的值应单独视为标准值。每个系统中规定的值可能不完全等同:因此，每个系统应独立使用。合并两个系统的值可能导致不符合标准。1.3 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.4 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》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 4.1 本指南旨在用于现浇混凝土施工中止水带的选择和安装。本指南旨在帮助建筑业主、业主代表、建筑师、工程师、承包商和/或授权检查员制定和安装止水带。4.2 本指南适用于现浇混凝土施工。本指南的使用可能不适用于在其他类型的混凝土结构中安装止水带，包括但不限于气动（即喷射混凝土）和预制混凝土结构。

1.1 This guide covers the use of waterstops within cast-in-place concrete construction. Waterstops are generally placed within static, non-moving construction joints in concrete to close off the joint to water, which may be under significant hydrostatic pressure. They are used as part of the overall waterproofing strategy for a building or other structure. Expansion and other types of moving joints may require the use of waterstops, which can accommodate the anticipated movement of the structure and are beyond the scope of this guide. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.3 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. 1.4 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 ====== 4.1 This guide is intended to be used in the selection and installation of waterstops in cast-in-place concrete construction. This guide is intended to assist the building owner, owner’s representative, architect, engineer, contractor, and/or authorized inspector during the specification and installation of waterstops. 4.2 This guide is applicable to cast-in-place concrete construction. The use of this guide may not be appropriate for installation of waterstops in other types of concrete construction, including but not limited to, pneumatically applied (that is, shotcrete) and precast concrete construction.
