一、防護欄桿的設置:
1、 Installation of protective railings:
肢體操作防護欄桿主要用于防止人員墜落。它能承受一定的沖擊或沖擊,在機械性能方面能承受1000牛頓的外力,從而保證安全。當臨邊防護工作面邊緣無防護設施或圍欄低于80厘米時,應按規(guī)定設置防護欄桿。設置防護欄桿的要求如下:
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.防護欄桿由上下欄桿和欄桿組成。上軌離地高度為1.0m~1.2m,下軌離地高度為0.5m~0.6m,如果軌長超過2m,需要加欄桿。
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.欄桿柱與橫桿固定連接,其整體結構應使上桿上的防護欄桿無處不在;
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.圍欄需要上下用密目封閉,或在欄桿底部設置高度不小于18厘米的腳板,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、防護欄桿應涂上醒目的安全顏色。
4. Protective railings should be painted with eye-catching safety colors.
5.樓梯和通道保護結構已連接。
5. The protective structures for stairs and passages have been connected.
二、臨邊防護欄安裝的注意事項:
2、 Precautions for installing edge guardrails:
1.上桿距地面1.2m,下桿距地面0.5~0.6m,坡度大于1,333,602.2的屋面,防護欄桿高度為1.5m,并設置安全網(wǎng)。除設計計算外,鋼軌長度超過2m,必須增加鋼軌立柱。
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.欄桿立柱的固定應符合下列要求:
2. The fixation of railing columns should meet the following requirements:
a、基坑周圍固定時,可使用鋼管打入50 ~ 70厘米深的地面。鋼管與側口之間的距離不得小于50厘米。當基坑周圍采用板樁時,鋼管可以放在板樁的外面。
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、混凝土樓板、屋面或墻體固定后,預埋件可用鋼管或鋼筋焊接。使用竹木欄桿時,可在預埋件上焊接30cm長的50*5角鋼,上下鉆一個孔,然后用10cm的螺栓用竹木桿固定。
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、當固定在磚或砌體等砌體上時,可預先用預埋鐵將符合規(guī)格的80*6排架扁鋼做成混凝土塊,然后用上述方法項固定。
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.欄桿柱的整體結構及其與橫桿的連接應確保防護欄桿能夠承受上部桿上任何方向1000牛頓的外力。當欄桿位置可能出現(xiàn)人群擁堵、車輛碰撞或物體碰撞時,應增加橫桿的橫截面或填充柱之間的距離。
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、防護欄桿需要自上而下用安全網(wǎng)封閉。
4. Protective railings need to be enclosed with safety nets from top to bottom.
