天然石料或混凝土路缘石与路边边沟以及混凝土护栏装置

注释

b) 高路缘石

(*) 应该在缓速道路出口处，对高路缘石进行一定的保护。

(**) 命名结构：高路缘石类型______，高度______，种类______。

c) 紧固件：

(*) 1978 年 5 月 3 日通过的部令中规定的：对公路交通信号设备、安全设备以及经营设备的一般审批条件，可单独使用在高速公路和对公共交通开放的公路上。

在本手册出版时，通行的唯一紧固件版本是 BN3 安全屏障（专利保护板版），在 SETRA（现为 GC77）指导卷中有定义说明。

3.3 现场浇筑的混凝土产品

a) 路缘石与路边边沟：

(*) 现场浇筑的路缘石与路边边沟的命名按照以下信息，

— 依其类型而定（预制产品类型鉴别为 A、P、T、CS、CC、I、CR 等，第 3.2.a 条注释）。

不论如何，现场浇筑的路缘石与路边边沟的命名借助预制路缘石的命名方式，这不能导致所有材料尺寸一样。

— 依其强度等级而定。

例如：名称：T3 同等路缘石就地浇筑，等级 B。

b) 高路缘石：

(*) 对于含有悬垂部分的工程，不要使用这项技术（参看图示）。

悬垂部分

b) 高路缘石：

高路缘石的高度高于正常路缘石，见下章所述(*)。

高路缘石按以下信息命名(**)。

— 以其高度；

— 以其类型；

— 按照外观和第 6.3 条定义说明的种类而定。

c) 护栏装置：

只用于与 1978 年 5 月 3 日颁布的部长法令的相符的装置。

3.3 现场浇筑的混凝土产品：

应区分以下概念：

a) 路缘石与路边边沟：

现场浇筑的路缘石与路边边沟的命名和等级划分，与同类预制产品相同，按照类型与强度予以确定。强度等级 A、B 和 C，按照第 7.5 条所述条件，根据工程混凝土力学特性划分。

b) 高路缘石：

高路缘石的命名类似于预制高路缘石，按照以下特点：

— 其高度；

— 其种类；

— 有时还要加上其类型。

Foreword

This document (EN 10216-3:2002) has been prepared by Technical Committee EC/TC 29, "Steel tubes and fittings for steel tubes", the secretariat of which is held by UNI.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by November 2002.

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.

ISO 657-1 : 1988 (E)

Table 1 — Dimensions and sectional properties of hot-rolled equal-leg angles (concluded)

NOTES

1. Member countries may choose, to be included in their national standards, the sizes which are required to meet their demand.
2. For the angles so chosen, only thicknesses which can be rolled in their mills to meet the demand of the users may be selected from the list of thicknesses corresponding to equal angles in table 1.
3. The sectional area has been calculated using the formula

   S = [l/2 A - l) + 0,214 6 (r_root² - 2r_toe²)] × 1/100

   where
   

   S is the sectional area, in square centimetres;
   

   l is the thickness, in millimetres;
   

   r_root is the root radius, in millimetres;
   

   r_toe is the toe radius, in millimetres;
   

   A is the leg length, in millimetres.

4. Mass is calculated on the basis of density of steel of 7,85 kg/dm³.
