It is an important and most important part of the balcony, which mainly plays a role of safety protection. Modern life also pays more attention to the beautiful decoration function. Not only are the guardrails safe in style, strong and durable, and reasonable in location, they must also have adequate protection capabilities. But many of the things we have installed in our lives now have problems:

 

　　 1. The styling design is unreasonable

 

　　According to national construction standards, the clearance between the vertical bars of the guardrail should not be greater than 0.11m. And measures must be taken to prevent children from climbing, but we find that we often see many sad things in life because of the unreasonable design of the vertical pole spacing or the lack of design to prevent children from climbing. In order to eliminate such problems, the design unit should first clearly indicate in the drawings which type of railing to adopt. If the construction unit needs to decide on its own, it should be confirmed by the supervisor and design unit after selection before it can be adopted. However, some construction units single-sidedly emphasized beauty and ignored the most important safety protection functions, resulting in unreasonable railing spacing and patterns, leaving hidden safety hazards.

 

　　2, insufficient height

 

The national standard requirement is that the height of the ground to the handrail surface is at least 1.1 meters, and the top railing requires at least 1.2 meters. However, many buildings are designed because of the lack of common sense of the designers or to save costs, and many heights fail to meet the national requirements. . At the same time, pay attention to the measurement position when checking the height of the armrest.

 

　　 3. Improper installation location

 

The installation position of 　　 must be accurate, the handrail method must be selected reasonably, and the detailed design must be done in advance before installation. The correct installation position should be installed in the center of the retaining wall. If there is no retaining wall, the fixed point of the column must be at least 10 cm from the edge of the balcony. Too close to the edge will affect the firmness of the fixed point.

 

　　 4. Improper selection of materials

 

　　 should be made of strong and durable materials. When metal pipes are used for railings, the pipe diameter and pipe wall thickness should meet the design requirements.
