金属网状梁和柱ce认证标准-ETA认证

EAD 130031-00-0304: 2018 METAL WEB BEAMS AND COLUMNS 金属网状梁和柱

Metal-web beams and columns are shallow parallel-chord trusses in which timber flanges are connected to each other by a system of triangulation provided by steel webs. A web is a thin gauge steel member that is fixed to the flanges of the beam or column by the pressed insertion of integral nail-plates. A metal web beam or column always has webs on both of the wider faces of the beam or column, although the arrangement of the webs on one face may not be the symmetrical opposite of the other face. A typical beam is shown in elevation in Figure 1 and in cross-section in Figure 2. This EAD covers beams or columns of any depth.

上海郜盟提示金属网架梁和柱是一种浅平平行弦桁架结构，其中木材翼缘通过由钢网提供的三角连接系统相互连接。网架是一种薄规格钢构件，通过整体钉板压入的方式固定在梁或柱的翼缘上。金属网架梁或柱通常会在梁或柱较宽的两面都设有网架，尽管一面上的网架布局可能并非与另一面对称相反。图1中展示了典型梁的立面图，图2展示了其横截面图。此EAD适用于任何深度的梁或柱。

The flange must provide sufficient material for insertion of all the teeth of the nail-plates without overlap between opposing nail-plates. For any particular type and size of integral nail-plate, the minimum section depth and width dimensions of the flange shall be specified in the ETA, with a minimum cross-section area of 2000 mm2.

法兰必须提供足够的材料，以便容纳钉板上的所有齿，且相邻的钉板之间不存在重叠。对于任何特定类型和尺寸的整体钉板，法兰的最小截面深度和宽度尺寸应在ETA中予以规定，最小横截面面积为2000平方毫米。

The flanges may be of strength graded solid timber or of structural glued laminated timber. Where necessary the flanges may be end-jointed using punched metal plate fasteners (known as splice plates) pressed into the top and bottom faces of the flanges (Figure 3).

法兰盘可采用强度分级实心木材或结构用胶合层压木材制成。如有必要，法兰盘可采用端部接合方式，使用冲制金属板紧固件(俗称接合板)压入法兰盘的上、下表面(图3)。

The webs are typically produced in end-joined pairs, called V-webs. On elevation the V-webs have integral nailplates at each end and at the root of the V-web as shown in Figure 4. These nailplates are pressed into the sides of the flanges to form triangulated frameworks of the type shown in Figure 1. For beams and columns or parts of beams and columns under high load,double webs may be used whereby two webs are placed adjacent and parallel to each other on each side of the flanges as shown in Figure 5. Figure 5 also shows that half V-webs are used to make up a double web at the end of a joist, whilst in the middle of a joist double webs are generally achieved by up-turning alternate V-webs. Beams and columns with spans that are not multiples of the nominal horizontal module of the V-web must have sufficient strength and stiffness along their entire length

网板通常以端部拼接对的形式生产，称为V型网板。从立面看，V型网板两端及根部均有完整的钉板，如图4所示。这些钉板被压入法兰板的侧面，从而形成如图1所示的三角形框架结构。对于承受高载荷的梁和柱或梁柱部件，可使用双网板结构，即两侧的网板彼此相邻且平行放置，如图5所示。图5还表明，在搁栅的末端，使用半V型网板来构成双网板结构;而在搁栅中部，通常通过翻转交替排列的V型网板来实现双网板结构。跨度并非为V腹板名义水平模数倍数的梁和柱，其全长必须具有足够的强度和刚度。

The example methods below of achieving any length of metal-web beams may be followed:

1.A Vierendeel bay is formed in the joist by fixing two short timber verticals between the flanges as shown in Figure 6 where the distance between the timber verticals does not exceed the horizontal module of the steel V-web

2.The metal-web triangulation is discontinued locally such that the final webs on opposite sides of the non-triangulated zone are parallel to each other as shown in Figure 7. The maximum extent of the non-triangulated zone along either flange is half the horizontal module of the steel V-web.

3.The metal-web triangulation is discontinued locally with a vertical timber post fixed equidistant from the nearest metal webs as shown in Figure 8. The maximum distance along either flange from the centre of the post to the nearest integral nailplate is half the horizontal module of the steel V-web.

以下是实现任何长度金属网梁的示例方法，可供参考:

1. 在搁栅上通过固定两根短木料垂直件于翼缘板之间（如图 6 所示）而形成一种维伦代尔式海湾结构，其中木料垂直件之间的距离不超过钢 V 横肋的横向模块

2.金属网三角结构已在局部区域停止使用，这样一来，非三角区域两侧的最终网片将彼此平行，如图 7 所示。沿任一翼缘方向的非三角区域最大范围为钢 V 网横向模块的一半。

3.金属网架三角结构已在局部区域停止使用，取而代之的是垂直的木桩结构，该木桩固定在与最近金属网架等距的位置上，如图 8 所示。沿任何一侧翼缘从木桩中心至最近整体钉板板面的最大距离，为钢 V 型网架水平模块的一半。

If other methods or models for achieving alternative lengths of metal-web members are developed, these shall be verified by calculation to EN 1995-1-1.

若开发出其他方法或模型以实现不同长度的金属网构件，则这些方法或模型须通过计算验证是否符合 EN 1995-1-1 标准。

This EAD provides for the flanges of the metal-web beams and columns to be made of preservative or fire retardant treated timber. It does not include within its scope fire retardant coatings that may be applied post-fabrication.

本 EAD 规定金属网梁和柱的法兰盘应采用经防腐剂或阻燃剂处理的木材制成。其适用范围不包括可能在制造后施用的阻燃涂层。

 

What is an EAD?什么是EAD？

A European Assessment Document, or EAD for short, is a harmonised technical specification developed by EOTA as the basis for European Technical Assessments (ETAs).上海郜盟提示欧洲评估文件（简称EAD）是由欧洲技术认证组织（EOTA）制定的统一技术规范，作为欧洲技术评估（ETA）的基础。

In combination with the ETA, the EAD provides manufacturers with a way to CE marking for construction products that are not or not fully covered by a harmonised European standard (hEN) under the Construction Products Regulation (EU) 305/2011. The CE marking allows the manufacturer to freely market his product in the entire European Economic Area as well as in Switzerland and Turkey.

结合ETA，EAD为制造商提供了一种对未被或未完全被《建筑产品法规》（EU）305/2011所涵盖的协调欧洲标准（hEN）覆盖的建筑产品进行CE标志认证的途径。获得CE标志后，制造商即可在全部欧洲经济区以及瑞士和土耳其自由销售其产品。

Finished floor or ceiling covering as well as possible sound reducing materials are not part of the kit.

完成的地板或天花板覆盖物以及可能的隔音材料不属于套件的一部分。

This EAD is not applicable when

-timber treatments (preservatives, fire and flame retardants) are used, and/or

-recycled material is used.

此 EAD 在下列情况下不适用:

-木材处理工艺（防腐剂、防火阻燃剂）被应用于其中，且/或

-使用了回收材料。

Concerning product packaging, transport, storage, maintenance, replacement and repair it is the responsibility of the manufacturer to undertake the appropriate measures and to advise his clients on the transport, storage, maintenance, replacement and repair of the product as he considers necessary.

关于产品的包装、运输、储存、维护、更换和修理事宜，制造商有责任采取相应措施，并在其认为必要的情况下向客户提供有关产品运输、储存、维护、更换及修理方面的建议。

It is assumed that the product will be installed according to the manufacturer's product installation instructions (MPl) or (in absence of such instructions) according to the usual practice of the building professionals

假定该产品将按照制造商的产品安装说明（MPl）进行安装，或者在无此类说明的情况下，则按照建筑专业人员的惯常做法进行安装

Relevant manufacturer's stipulations having influence on the performance of the product covered by this European Assessment Document, shall be considered for the determination of the performance and detailed in the ETA.

对于本欧洲评估文件所涵盖产品的性能判定，应考虑相关制造商的规定，这些规定会对产品性能产生影响，相关内容将在 ETA 中予以详细阐述。
