临边防护常用的防护栏也叫做基坑护栏，基坑护栏是指基坑周边用定型或钢管搭设而成的防护栏杆，主要作用是防止人员坠落到基坑内，是一种新型的防护设施。临边护栏根据实际使用环境设计出了很多类型，那么常用的类型是哪几种呢？下面小编为您讲解。

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、网片型：

1、 Mesh type:

网片型临边护栏网丝的直径通常3mm的镀锌丝，网孔大小为50*50mm，立柱为50*50mm，边框为20*20mm，下部挡脚板的宽度在150-200mm之间，连接件（耳朵）常用尺寸50*50mm，厚度3mm。底盘常用尺寸120*120mm，厚度4mm。框网和立柱之间使用专用螺丝进行固定，底盘与地面使用8*80或10*80膨胀螺丝固定。

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、栏杆型（竖管型）

2、 Handrail type (riser type)

栏杆型临边护栏是用边框20*30mm的方钢与内竖管20*20mm的方钢焊接而成，立柱常用搭配规格为40*40mm或50*50mm方钢（其他数据请参考以上网片型常用规格粗体字说明。）

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.)

临边护栏焊接完成后，为了使它的外表更加美观醒目且增强防锈能力，需要对护栏进行表面防锈、防腐处理，表面处理经常使用静电喷漆的方式，颜色分为黑黄或红白醒目的警示色。

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.

临边护栏的安装通常使用简便式安装，配套螺丝随临边护栏配套发货，临边护栏中间钢板可喷涂“注意，禁止翻越”等警示字样，也可根据实际环境需求设计喷漆字样。

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.

临边护栏施工属于具有一定危险系数的施工场合，临边护栏护栏的设计主旨在于警示和防护作用，是施工防护中重要的环节，为了施工人员的，严禁随意拆除、蓄意破坏。更多相关注意事项就来我们网站http://www.jnpfjc.com进行咨询了解吧！
