來源:http://www.btmj.net/   發(fā)布時間:2021-11-15

一、臨邊防護(hù)欄需采用工具化和定型化,規(guī)格尺寸以及連接方式應(yīng)符合相關(guān)要求。

1、 The edge guard shall be tooled and shaped, and the specification, size and connection mode shall meet relevant requirements.
二、防護(hù)欄由上下橫桿、邊框以及內(nèi)豎管或網(wǎng)片焊接而成,上桿離地1.1-1.2m,下桿離地0.5-0.6m,當(dāng)橫桿長度達(dá)到2m以上時,需要加設(shè)專用立柱。
2、 The protective fence is welded by upper and lower cross bars, frames and inner vertical pipes or nets. The upper bar is 1.1-1.2m above the ground and the lower bar is 0.5-0.6m above the ground. When the length of the cross bar reaches more than 2m, special columns need to be added.
三、防護(hù)欄需自上而下加設(shè)密網(wǎng)封閉,在欄桿下部應(yīng)設(shè)置高度18cm以上的擋腳板,擋腳板刷紅白或黑黃相間的條形警示漆。

3、 The protective fence shall be closed with a safety dense net from top to bottom. A toe board with a height of more than 18cm shall be set at the lower part of the railing, and the toe board shall be painted with red, white or black and yellow strip warning paint.
四、防護(hù)欄安裝固定需牢固,欄面與橫桿的連接應(yīng)能承受來自任何方向1000N的外力沖擊。
4、 The protective fence shall be firmly installed and fixed, and the connection between the fence surface and the cross bar shall be able to withstand the impact of 1000N external force from any direction.
五、在接料平臺兩側(cè)使用時,需自上而下加掛密網(wǎng)。
5、 When used on both sides of the receiving platform, a safety dense net shall be hung from top to bottom.
六、當(dāng)臨邊護(hù)欄使用在街道附近時,除防護(hù)欄桿外,敞口立面還需滿掛密網(wǎng)作全封閉處理。
6、 When the edge guardrail is used near the street, in addition to the protective guardrail, the open facade needs to be fully hung with safety dense net for full sealing treatment.
