With the support of the state for the modernization transformation of the construction industry, the construction industry will enter an unprecedented peak, and more and more steel structure buildings will be reflected in people’s eyes.Steel structure is widely used in high-rise buildings because of its light weight, short construction period and strong seismic capacity.With the increase of steel structure engineering, the problems in the project are gradually exposed. For more than ten years since 3D steel structure has been engaged in the construction industry, the safety in the construction process of steel structure is summarized as follows.

 1、 The necessity of safety protection in steel structure construction

 In the process of steel structure installation, due to its special working conditions and working environment, the safety of steel structure construction process is determined.Due to the steel structure building in the process of welding work, need more manual operation, low degree of mechanization leads to the continuous increase of welding personnel construction, logistics security protection construction of some construction teams in our country is relatively backward, lack of capital investment, safety protection measures are not in place, resulting in poor safety protection conditions on the construction site.

2、 The process of steel structure construction is complicated and diverse

 In the process of steel structure building, it is necessary to distinguish the construction types of steel structure, which are mainly divided into space steel structure, residential steel structure, high-rise steel structure, light steel structure and heavy steel structure.And from the factory steel structure shipping to the construction site for resettlement construction, according to a certain process, the implementation of lifting, mobile assembly, alignment, fixed placement, welding connection step by step.In the construction of steel structure, the welding technology is mostly used for manual arc welding. If necessary, gas welding, protective welding, tungsten electrode welding, argon arc welding and other methods are used. The grinding machine cutting method is also used in the cutting process. Pay attention to the safety in the construction process.

 3、 Bad working environment of electric welding

 In the process of steel structure construction, a large number of electric welding processes are required. However, the working environment of welding site is complex and lack of safety guarantee. For example, most of the work is carried out in the open field, which will face the situation of sun exposure and wind and rain. When working at high altitude, the temperature is high, and the ground is far away, and the safety is low.There are many operation obstacles in these operation sites, and the speed of position change is fast, which is very inconvenient in the process of transformation.If the construction site is small and there are many equipment stacked, it will cause great potential safety hazard. If the construction personnel are exposed to electric welding work for a long time, they can work under the conditions of inflammable and explosive, high temperature and strong radiation, and take corresponding measures to reduce the impact on the physical and mental health of construction personnel.
