11、r 2004 Foreword This part of BS 5516 has been prepared by Technical Committee B/520. This part of BS 5516, together with BS 5516-2:2004, supersedes BS 5516:1991, which is withdrawn. It revises all or part of Clauses 1 to 3, 5 to 9, 10.3 to 10.5, 10.6.2, 10.6.3, 10.8, 11 to 14, 19, 20.1, 20.3, 20.4,
12、21 to 24, 25.1, 25.2, 25.4, 25.6, 25.8, 25.9, 26 to 29 and Annex A to Annex F and Annex J to Annex K of BS 5516:1991. BS 5516:1991 has been revised and restructured to simplify its use and will be published in three parts covering the following areas: Part 1: Code of practice for design and installa
13、tion of sloping and vertical patent glazing; Part 2: Code of practice for sloping glazing; Part 3: Special applications. Requirements for standards of workmanship for glazing have been published separately as BS 8000-7 and, therefore, this subject is not dealt with in this standard. Since the correc
14、t selection of materials to be used in glazing for buildings depends on many factors, attention is drawn to the recommendations in the other parts of this standard. As a code of practice, this British Standard takes the form of guidance and recommendations. It should not be quoted as if it were a sp
15、ecification and particular care should be taken to ensure that claims of compliance are not misleading. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard does not of itself co

17、ntroduction Patent glazing is the term applied to a self-draining and ventilated system of dry glazing that does not rely entirely for its watertightness upon external glazing seals. It consists essentially of a series of longitudinal glazing bars, i.e. patent glazing bars, and an infilling of glass
18、 or other suitable infill material. Patent glazing bars are attached to and supported by structural members, either directly or indirectly. Patent glazing systems are described by the number of edges by which the infilling is supported. They are generally unsealed, at the interface with the building
19、 substrate relying on flashings and/or formed weatherings for weathertightness. They differ from sloping curtain wall systems which form sealed airtight constructions. Curtain wall systems designed for vertical application might not be suitable for sloping application, unless they incorporate a slop
20、ing application drainage facility or are face sealed to exclude water from the glazing rebates. a) Two-edge systems are those in which the infilling is fully supported by patent glazing bars on two opposite longitudinal edges only. Horizontal flashings or other weatherings are normally provided at t
21、he top and bottom edges of single tier glazing and at junctions of glazing of more then one tier. b) Four-edge systems are those in which the infilling is fully supported by patent glazing bars on two opposite longitudinal edges and additionally on the other two edges by transom members. BS 5516-1:2
22、004 2 BSI 26 November 2004 1 Scope This British Standard gives recommendations for the design, manufacture, installation and maintenance of sloping and vertical patent glazing systems attached to and supported by structural members of adequate strength, stiffness and stability. All recommendations a
23、pply to flat, including faceted, patent glazing and infilling. They may also apply to curved patent glazing and infilling except for the structural design where specialist advice is needed. The patent glazing systems included in this standard comprise glazing bars of aluminium or steel, which can be
24、 clad totally or partially clad with lead or PVC-U, for two-edge support and four-edge support systems for single and double glazing or other infill. A range of transparent and opaque infillings of glass, plastics glazing sheet materials and other infill materials are included; specific information
25、on plastics glazing sheet materials is given in BS 5516-2:2004, Annex A. This standard covers the use of patent glazing in permanent buildings and structures, including conservatories but excludes greenhouses. Clauses that are relevant also apply to the use of patent glazing inside buildings. This s
26、tandard does not include recommendations for the design of the supporting structure to which the patent glazing is attached. Requirements for standards of workmanship for glazing have been published separately as BS 8000-7 and, therefore, this subject is not within the scope of this standard. Since
27、the correct selection of materials to be used in glazing for buildings depends on many factors, attention is drawn to the recommendations in the other parts of this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
