3.15 meter squared X 22.7 Kg per squared meter = 71.5 Kg -Total working load (35 square feet x 50 p.s.f. = 1,750 pounds Total working load). 例如：整块原木

每平方米工作负荷22.7 Kg（50 lb/平方英尺） 允许跨距2.4m (8英尺)

3.15 平方米 X 22.7 Kg/平方米= 71.5 Kg——总工作负荷（35 平方英尺 x 50 p.s.f. = 1,750磅总工作负荷）。

Example: Nominal thickness lumber (dressed)

Working load 11.1Kgs per square meter (25Lbs per square foot)

3.15 meters squared X 11.1 kgs per squared meter = 35 Kgs -Total working load (35 square feet x 25 p.s.f. = 875 pounds - Total Working Load) 例如：公称厚度木料（加工）

工作负荷11.1Kgs/平方米（25Lbs/平方英尺）

3.15 平方米X 11.1 kgs/平方米 = 35 Kgs——总工作负荷（35平方英尺 x 25 p.s.f. = 875磅——总工作负荷）

NOTE: FOR PERMISSIBLE SPAN - USE THE NEXT HIGHER NUMBER FOR LENGTH OF SPAN.

注：关于允许间距——使用次高数目的间距长度。

4.3.8 Scaffold planking shall be scaffold grade as recognized by grading

rules for the species of wood and stamped on the plank.

要根据木材种类和铺板上打印的标记的分类原则，铺设脚手架铺板。

4.3.9 When a scaffold is built around a line or object, the following guidelines are to be followed:

当脚手架在一条管线或一个物体的周围架设时，要遵循以下指导原则：

4.3.9.1 Toe-board shall be installed around the object. 在物体周围安装隔板。

4.3.9.2 Planking shall be covered with plywood 15.87 mm (5/8\greater and capable of supporting the intended load.

铺板上要覆盖一层厚度等于或大于15.87 mm (5/8英寸)的胶合板并且必须能够承受拟定的负载。

4.3.9.3 Scaffolds shall be planked end-to-end on each side of the object. The planking needs to be supported around the object to ensure the decking or planking will sufficiently hold the intended weight of people and tools and materials.

脚手架铺板必须与物体的各侧接触。铺板需要围绕物体的周围支撑，以确保台面或铺板足以承载人员、工具和材料的预期重量。

4.3.10 All brackets shall be seated correctly with side brackets parallel to frames and end brackets 90° to the frame. Brackets shall not be bent or twisted from normal positions.

所有的托架都必须正确布置，侧向支架要与框架平行，端部支架要与框架呈90°角。托架不得弯曲或从正常位置扭曲。

4.3.11 Scaffolds shall be visually checked by the user prior to use to ensure that no unauthorized changes have been made and that the status tag is still valid. If the tag is not valid, the scaffold shall be removed from service by removing the scaffold tag until repairs are made and the scaffold has been re-inspected. A red tag should be fixed to the scaffolding indicating no one is to use it.

脚手架在使用前要经过使用人的肉眼检查，以确保没有未经授权的变更并且脚手架状态标牌仍然有效。如果标牌失效，必须摘下，脚手架退出使用，直至完成对脚手架的修理并重新通过检验为止。不准任何人使用的脚手架上应该悬挂红色标牌。

4.3.12 Where gin wheels/pulleys (including ropes) or other accessories are fitted to the scaffold, these are to be included into the scope of all inspections mentioned in this procedure.

如果脚手架上装配辘轳/滑轮（包括绳索）或其它附件，这些设备都必须纳入本程序所述的所有检查范围。

4.3.13 When it is proposed to use a lightweight mobile scaffold platforms for light duty work, the scaffold shall be subject to the following:

在建议使用轻便型活动式脚手架从事轻便工作时，脚手架必须符合以下条件：

4.3.13.1 The scaffold is used with all bracing and outriggers in position and wheels locked.

脚手架的所有支撑和外伸支架都要安装就位，所有轮子锁定。

4.3.13.2 All scaffold is used on level firm ground only. 脚手架都只准在水平、坚硬的地面上使用。

4.3.13.3 All points of the scaffold are fully supported by the ground. 脚手架的所有各点位都由地面完全支撑。

4.3.13.4 The individuals erecting the scaffold have been properly trained in its use.

安装脚手架的人都已接受过关于脚手架用途的培训。

4.3.13.5 The height of the scaffold shall not exceed the smallest base dimension by a factor greater than 3:1, subject to the manufacturer confirming that the scaffold is suitable for this and that the manufacturer instruction and information are available. If no information exists, assume 2:1 as the maximum ratio. Additionally, the smallest base dimension shall not be less than 1200 mm (4' feet).

脚手架的高度不得超过最小基本尺寸（用大于3:1的因数计算的尺寸），除非制造厂确认脚手架适合使用并且持有制造厂的说明书和资料。如果没有这类资料，假定按2:1的最大比率计算。另外，最小基础尺寸不得小于1200 mm (4英尺)。

4.3.13.6 Ladders must not be used to extend the height of the scaffold. 不得用梯子来延伸脚手架的高度。 …… 此处隐藏：2381字，全部文档内容请下载后查看。喜欢就下载吧 ……
