工地臨時(shí)護(hù)欄的幾點(diǎn)使用須知

來源:http://www.xalianjia.com/   發(fā)布時(shí)間:2022-10-03

在施工工地建設(shè)時(shí),由于施工中存在很多的危險(xiǎn)環(huán)境,所以大多數(shù)的工地都會(huì)選擇安裝工地護(hù)欄,工地護(hù)欄一般用于臨邊環(huán)境中,例如坑、溝、槽邊、基坑周邊以及樓層周刊等。下面來講講工地臨時(shí)護(hù)欄的幾點(diǎn)使用須知。
During the construction of the construction site, because there are many dangerous environments during the construction, most of the construction sites will choose to install site guardrails. Site guardrails are generally used in the edge environment, such as pits, ditches, groove edges, foundation pit periphery and floor weekly. Here are some instructions for the use of temporary guardrails on the construction site.
工地護(hù)欄只有在工地施工進(jìn)行時(shí)進(jìn)行安裝,安裝步驟簡(jiǎn)單明確,使用完后需要進(jìn)行拆除以便于重復(fù)利用。因此這種護(hù)欄也常被稱為臨時(shí)護(hù)欄。臨時(shí)護(hù)欄的使用場(chǎng)合很,在不的環(huán)境中對(duì)護(hù)欄有不的要求,我們挑選了幾種在常用環(huán)境中使用需要注意的事項(xiàng)。
The guardrail on the construction site can only be installed during the construction on the construction site. The installation steps are simple and clear. After use, it needs to be removed for reuse. Therefore, this kind of guardrail is also often called temporary guardrail. Temporary guardrails are used in many occasions. There are no requirements for guardrails in different environments. We have selected several items that need attention when using them in common environments.
1)分段施工的樓梯口和梯段邊要裝工地臨時(shí)護(hù)欄,樓梯口應(yīng)隨工程結(jié)構(gòu)的進(jìn)度安裝正式護(hù)欄或工地臨時(shí)護(hù)欄。梯道旁的一遍應(yīng)設(shè)置扶手。
1) Temporary guardrails on the construction site shall be installed at the stairway entrances and stairway edges for sectional construction, and formal guardrails or temporary guardrails on the construction site shall be installed at the stairway entrances on the top floor according to the progress of the engineering structure. Safety handrails shall be set at the first layer beside the stairway.
臨時(shí)護(hù)欄
2)垂直運(yùn)輸設(shè)備中也需要安裝臨時(shí)護(hù)欄,如:井架、施工電梯、建筑物連接通道兩側(cè)等。在這些場(chǎng)合中使用時(shí),臨時(shí)護(hù)欄的下部需要設(shè)置擋腳板。地面上通道的頂部還需要設(shè)置防護(hù)棚。雙籠井架通道中間的左右兩部應(yīng)予以分割封閉。
2) Temporary guardrails also need to be installed in the vertical transportation equipment, such as: derrick, construction elevator, both sides of the building connecting channel, etc. When used in these occasions, toe boards need to be set at the lower part of the temporary guardrail. The top of the passage on the ground shall also be provided with a safety protection shed. The left and right parts in the middle of the double cage mast passage shall be separated and closed.
3)基坑周邊、為安裝欄桿和欄板的陽(yáng)臺(tái)、料臺(tái)以及各種平臺(tái)周邊、雨蓬與挑檐邊、屋外腳手架的屋面和樓層周邊、水箱、水塔周邊等,在這些環(huán)境中都要安裝基坑臨時(shí)護(hù)欄。
3) Temporary guardrails for foundation pits shall be installed around the foundation pits, balconies for installing handrails and breast boards, material platforms and various platforms, awnings and cornices, roofs and floors of outdoor scaffolds, water tanks and water towers.
