臨邊護欄規(guī)范以及作用是怎樣的?

臨邊護欄是工地文明施工標準化的重要防護,那么臨邊護欄規(guī)范以及作用是怎樣的?臨邊護欄規(guī)范和標準規(guī)定如下:
The edge guardrail is an important protection for the standardization of safe and civilized construction on the construction site. What are the specifications and functions of the edge guardrail? The specifications and standards for edge guardrails are as follows:
臨邊護欄標準規(guī)范:
Standard specifications for edge guardrails:
基坑開挖深度達到2m及以上時,周邊必須安裝防護欄桿。欄桿高度不宜低于1.2m,立桿之間不宜大于2m。臨邊護欄有很多種,一般使用比較醒目的紅白和黑黃顏色。
When the excavation depth of foundation pit reaches 2m or more, protective railings must be installed around it. The height of the railing should not be less than 1.2m, and the distance between the upright poles should not be more than 2m. There are many kinds of edge guardrails, and the striking red white and black yellow colors are generally used.
使用臨邊護欄欄桿還具有以下這幾點作用:
The use of edge guardrails also has the following functions:
1、使工地更加整潔美觀、文明。
1. Make the construction site more clean, beautiful, civilized and safe.
2、預(yù)防過往機動車輛靠太近基坑邊緣而造成塌方。
2. Prevent the collapse caused by passing motor vehicles getting too close to the edge of the foundation pit.
臨邊護欄
3、防止工人不小心掉入基坑。防止雜物掉入基坑,從而對基坑內(nèi)作業(yè)人員造成傷害。
3. Prevent workers from accidentally falling into the foundation pit. Prevent sundries from falling into the foundation pit, thus causing injury to operators in the foundation pit.
我們在選購臨邊護欄的時候,一般對臨邊護欄高度也是有要求的,如果臨邊護欄高度達不到標準,則臨邊護欄就不能夠發(fā)揮其應(yīng)有的作用。那么臨邊護欄高度應(yīng)符合什么標準呢?
When purchasing edge guardrails, we generally have requirements for the height of edge guardrails. If the height of edge guardrails fails to meet the standard, the edge guardrails cannot play their due role. What standard should the height of edge guardrail meet?
但凡標準的大型工地施工作業(yè)都需要符合JGJ80-2016《施工高處作業(yè)技術(shù)規(guī)范》及JGJ59-2011《建筑施工檢查標準》。
All standard large-scale site construction operations shall comply with JGJ80-2016 Technical Code for Safety of Construction Work at Heights and JGJ59-2011 Standard for Safety Inspection of Building Construction.
此外在使用臨邊護欄時其高度可以高于標準高度,但一定不能夠小于標準高度,過高沒有作用,過低則起不到相應(yīng)的作用。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://www.diaoxx.com咨詢吧!
In addition, when using the edge guardrail, its height can be higher than the standard height, but it must not be lower than the standard height. If it is too high, it will not work, and if it is too low, it will not work. More relevant content will come to our website http://www.diaoxx.com Consult!
