BS英标:混凝土与砌体后锚固选择安装规程 8539-2012.pdf简介:
"混凝土与砌体后锚固选择安装规程 8539-2012.pdf" 是一份关于混凝土和砌体结构后锚固技术的安装标准和指南。该规程由中国建筑科学研究院发布,编号为8539-2012,旨在规范和指导在已建结构中(如混凝土和砌体结构)进行后锚固(如安装锚栓、膨胀管等)的设计和施工过程。后锚固技术常用于结构加固、设备固定和扩建工程等,以增强结构的承载能力和连接性能。这份规程详细规定了锚固件的选择、锚固深度、安装方法、质量检验等方面的要求,确保了施工的安全性和结构的稳定性。

5.3.3Base material
BRITISH STANDARD
Not all anchors work in all base materials, so the specifier should ensure that the proposed anchors are suitablefor thebase material concerned. NOTEGuidanceon concrete is given in 5.3.3.2,and on masonry in5.3.3.3
5.3.3.2Concrete
Productcertification/inspection/testing.UsersofthisBritishStandardareadvisedto considerthedesirabilityof selecting anchorswitha EuropeanTechnical Approval (ETA) 2).Annex D, Figure D.1 shows the selection process foranchors in concrete with andwithoutan ETA
5.3.3.2.1 Structural form
The specifier should evaluate thetype and strength of concrete structure,as there might be factors which could influence the choice of anchor or its positioning.

At the time of publication of this British Standard, it is expected that European Technical Approval Guidelines will be replaced by European Assessment Documents and European Technical Approvals will be replaced by European Technical Assessments upon implementation of EURegulation 305/2011(Construction Products Regulation)[2]in July2013

Structural dimensior
Specifiersshouldtakeinto accountthefollowingdimensionallimitationsofthe structure, as these limitations affect anchor performance.
a)Edgeandspacingparameters.
All anchors require an amount of the base materialaround them,to support the forces induced during their installation and/or those transferrec fromthe fixturein service.Datashould be acguired from themanufacturer identifying the edge distances and centre spacings that will provide full performance (characteristic edge distance, Cer or characteristic spacing, s.r), and absoluteminimum dimensions(minimumedge distance,Cminor minimum spacing, Smin), for which performance should be reduced accordin to the prescribed design model (see Figure 3). NOTE 1Anchors conforming to ETAG 001, Parts 1 to 5 ([8] and [11] to [14] will, depending on theiroption, include this data.Some options allow design using minimumdimensions, while others allow anchors tobe specified onlyat the critical distances with no closer dimensions allowed. There is, however, a relationship between the anchor spacing and the edge simultaneously with the minimum spacing, Smin. Minus tolerances should not be specified.
