一、防护栏杆的设置：

1、 Installation of protective railings:

肢体操作防护栏杆主要用于防止人员坠落。它能承受一定的冲击或冲击，在机械性能方面能承受1000牛顿的外力，从而保证安全。当临边防护工作面边缘无防护设施或围栏低于80厘米时，应按规定设置防护栏杆。设置防护栏杆的要求如下：

Limb operated protective railings are mainly used to prevent personnel from falling. It can withstand certain impacts or impacts, and can withstand an external force of 1000 Newtons in terms of mechanical performance, thereby ensuring safety. When there are no protective facilities at the edge of the edge protection working face or the fence is less than 80 centimeters, protective railings should be set up according to regulations. The requirements for setting up protective railings are as follows:

1.防护栏杆由上下栏杆和栏杆组成。上轨离地高度为1.0m~1.2m，下轨离地高度为0.5m~0.6m，如果轨长超过2m，需要加栏杆。

1. The protective railing is composed of upper and lower railings and railings. The height of the upper rail from the ground is 1.0m~1.2m, and the height of the lower rail from the ground is 0.5m~0.6m. If the rail length exceeds 2m, railings need to be added.

2.栏杆柱与横杆固定连接，其整体结构应使上杆上的防护栏杆无处不在;

2. The railing column is fixedly connected to the horizontal bar, and its overall structure should ensure that the protective railing on the upper bar is everywhere;

3.围栏需要上下用密目封闭，或在栏杆底部设置高度不小于18厘米的脚板，并固定牢固。

3. The fence needs to be closed with dense mesh above and below, or a foot board with a height of no less than 18 centimeters should be set at the bottom of the railing and fixed firmly.

4、防护栏杆应涂上醒目的安全颜色。

4. Protective railings should be painted with eye-catching safety colors.

5.楼梯和通道保护结构已连接。

5. The protective structures for stairs and passages have been connected.

二、临边防护栏安装的注意事项：

2、 Precautions for installing edge guardrails:

1.上杆距地面1.2m，下杆距地面0.5~0.6m，坡度大于1，333，602.2的屋面，防护栏杆高度为1.5m，并设置安全网。除设计计算外，钢轨长度超过2m，必须增加钢轨立柱。

1. The upper pole is 1.2m above the ground, and the lower pole is 0.5-0.6m above the ground. For roofs with a slope greater than 1333602.2, the height of the protective railing is 1.5m and a safety net is installed. In addition to design calculations, if the length of the steel rail exceeds 2m, additional steel rail columns must be added.

2.栏杆立柱的固定应符合下列要求：

2. The fixation of railing columns should meet the following requirements:

a、基坑周围固定时，可使用钢管打入50 ~ 70厘米深的地面。钢管与侧口之间的距离不得小于50厘米。当基坑周围采用板桩时，钢管可以放在板桩的外面。

a、 When fixing around the foundation pit, steel pipes can be used to drive into the ground at a depth of 50-70 centimeters. The distance between the steel pipe and the side opening shall not be less than 50 centimeters. When sheet piles are used around the foundation pit, steel pipes can be placed outside the sheet piles.

b、混凝土楼板、屋面或墙体固定后，预埋件可用钢管或钢筋焊接。使用竹木栏杆时，可在预埋件上焊接30cm长的50*5角钢，上下钻一个孔，然后用10cm的螺栓用竹木杆固定。

b、 After fixing the concrete floor slab, roof or wall, the embedded parts can be welded with steel pipes or steel bars. When using bamboo and wood railings, a 30cm long 50 * 5 angle steel can be welded onto the embedded parts, and a hole can be drilled up and down. Then, a 10cm bolt can be used to fix it with a bamboo and wood rod.

c、当固定在砖或砌体等砌体上时，可预先用预埋铁将符合规格的80*6排架扁钢做成混凝土块，然后用上述方法项固定。

c、 When fixed on bricks or masonry, the 80 * 6 truss flat steel that meets the specifications can be pre embedded with iron to make concrete blocks, and then fixed using the above methods.

3.栏杆柱的整体结构及其与横杆的连接应确保防护栏杆能够承受上部杆上任何方向1000牛顿的外力。当栏杆位置可能出现人群拥堵、车辆碰撞或物体碰撞时，应增加横杆的横截面或填充柱之间的距离。

The overall structure of the railing column and its connection to the crossbar should ensure that the protective railing can withstand an external force of 1000 Newtons in any direction on the upper pole. When there is a possibility of crowd congestion, vehicle collisions, or object collisions at the railing position, the cross-section of the crossbar or the distance between the filling columns should be increased.

4、防护栏杆需要自上而下用安全网封闭。

4. Protective railings need to be enclosed with safety nets from top to bottom.
