臨邊防護常用的防護欄也叫做基坑護欄，基坑護欄是指基坑周邊用定型或鋼管搭設而成的防護欄桿，主要作用是防止人員墜落到基坑內，是一種新型的防護設施。臨邊護欄根據實際使用環境設計出了很多類型，那么常用的類型是哪幾種呢？下面小編為您講解。

The commonly used guardrails for edge protection are also called foundation pit guardrails. Foundation pit guardrails refer to the guardrails built with shaped or steel pipes around the foundation pit, which are mainly used to prevent people from falling into the foundation pit. They are a new type of safety protection facilities. There are many types of edge guardrails designed according to the actual use environment. What are the common types? The following section explains it for you.

一、網片型：

1、 Mesh type:

網片型臨邊護欄網絲的直徑通常3mm的鍍鋅絲，網孔大小為50*50mm，立柱為50*50mm，邊框為20*20mm，下部擋腳板的寬度在150-200mm之間，連接件（耳朵）常用尺寸50*50mm，厚度3mm。底盤常用尺寸120*120mm，厚度4mm。框網和立柱之間使用專用螺絲進行固定，底盤與地面使用8*80或10*80膨脹螺絲固定。

The diameter of the mesh wire of the mesh type edge guardrail is generally 3mm galvanized wire, the mesh size is 50 * 50mm, the column is 50 * 50mm, the frame is 20 * 20mm, the width of the lower toe board is 150-200mm, the common size of the connector (ear) is 50 * 50mm, and the thickness is 3mm. The common size of chassis is 120 * 120mm, and the thickness is 4mm. Special screws are used to fix the frame mesh and the column, and 8 * 80 or 10 * 80 expansion screws are used to fix the chassis and the ground.

二、欄桿型（豎管型）

2、 Handrail type (riser type)

欄桿型臨邊護欄是用邊框20*30mm的方鋼與內豎管20*20mm的方鋼焊接而成，立柱常用搭配規格為40*40mm或50*50mm方鋼（其他數據請參考以上網片型常用規格粗體字說明。）

The railing type edge guardrail is welded with 20 * 30mm square steel of the frame and 20 * 20mm square steel of the inner riser. The commonly matched specification of the column is 40 * 40mm or 50 * 50mm square steel (For other data, please refer to the above bold description of the commonly used specifications of the mesh type.)

臨邊護欄焊接完成后，為了使它的外表更加美觀醒目且增強防銹能力，需要對護欄進行表面防銹、防腐處理，表面處理經常使用靜電噴漆的方式，顏色分為黑黃或紅白醒目的警示色。

After the edge guardrail is welded, in order to make its appearance more beautiful and eye-catching and enhance its anti rust ability, it is necessary to conduct surface anti rust and anti-corrosion treatment on the guardrail. The surface treatment often uses electrostatic spray paint, and the color is divided into black yellow or red white striking warning colors.

臨邊護欄的安裝通常使用簡便式安裝，配套螺絲隨臨邊護欄配套發貨，臨邊護欄中間鋼板可噴涂“注意，禁止翻越”等警示字樣，也可根據實際環境需求設計噴漆字樣。

The edge guardrail is usually installed in a simple way. The matching screws are shipped with the edge guardrail. The steel plate in the middle of the edge guardrail can be painted with warning words such as "Pay attention to safety, no climbing", or the words can be designed according to the actual environmental needs.

臨邊護欄施工屬于具有一定危險系數的施工場合，臨邊護欄護欄的設計主旨在于警示和防護作用，是施工防護中重要的環節，為了施工人員的，嚴禁隨意拆除、蓄意破壞。更多相關注意事項就來我們網站http://www.retraactit.com進行咨詢了解吧！

The construction of edge guardrails is a construction site with a certain risk factor. The design of edge guardrails is intended to serve as a warning and protection function, and is an important link in the construction safety protection. For the safety of construction personnel, it is strictly prohibited to dismantle or deliberately destroy them at will.
