What safety matters need to be paid attention to in steel structure construction?

There are many matters that need to be paid attention to during the construction of steel structures, which may cause unnecessary losses and safety hazards due to neglect.

Below, I will add some safety matters that you need to pay attention to in steel structure construction, come and take a look!

Safety construction measures

Implement the national labor protection policy and strictly implement the company's Relevant safe and civilized construction management systems and regulations.

The project manager is responsible for the construction site and implements the system of "whoever constructs is responsible for safety".

The project manager puts safety first in construction The responsible person is fully responsible for the safe construction on site.

The construction team leader is the specific leader of safe construction and is responsible for the implementation of safe construction in the construction area of ??the on-site team.

Safety and civilized management The safety officer of the team leader is responsible for the safe construction of the construction area of ??the team and implements specific safety construction measures.

Clarify the responsibilities for safe construction, assign responsibilities to each person, and take responsibility at all levels, and effectively implement safe construction.

Strengthen the education of "safety first", insist on briefing before class, and inspect during class, Monday regular meeting system.

Strengthen the publicity of safe construction, hang slogans and warning signs at prominent locations on the construction site to remind construction workers.

Wear safety helmets when entering the construction site.

Construction machinery and tools should be routinely inspected before use every day. In particular, wire ropes and safety belts should be checked for performance once a week to ensure they are in good condition.

During the installation process, on-site machinery and tools should be taken into consideration. Safety protection of equipment and completed projects.

When the wind speed is 10m/s, sometimes hoisting work should be stopped. When the wind speed reaches 15m/s, all work must be stopped.

Wear gloves when installing and handling components and panels.

If the wire rope is broken, broken or tangled during hoisting, it must be replaced immediately.

Special workers must hold valid certificates to work. .

At the end of the work day, the installed building must be properly supported to avoid accidents.

Always wear protective glasses when drilling.

Take safety protection measures on site, erect scaffolding in accordance with regulations, and only use it after passing the inspection

When installing wall panels, each operating platform of the mobile scaffolding used must be firmly fixed and made non-slip. To take measures, pull the protective rope and fasten the seat belt.

There are more than two pulling points between the mobile scaffolding and the wall, and two throwing braces are set up on the outside. The throwing braces need to be fixed on a solid and load-bearing surface. On the ground.

Before moving, clear the obstacles on the road ahead, fill in potholes, and compact the road before moving forward.

Before implementing each task, you should pay attention to the installation Workers repeatedly explain safety matters.

The company adopts a two-level safety supervision system to implement safety education and safety inspections. Special safety precautions

Lifting equipment operation requirements:

When hoisting, the crane should be commanded by a dedicated person. The commander should be located within the sight of the crane driver, and should be able to clearly see the entire hoisting process. The crane operator’s command gestures should be accurate, and the whistle should be bright. Drivers must concentrate, obey instructions, and are not allowed to leave their jobs without authorization.

When operations are interrupted due to equipment failure during the hoisting process, measures must be taken to deal with it, and components must not be left hanging for a long time. < /p>

Hoisting operations are prohibited when the wind force is greater than level 6.

Non-drivers are not allowed to enter the cab without permission. When the crane stops operating, the slewing and traveling mechanisms should be braked.

Lifting equipment is not allowed to work on slopes, and the height difference between the two sides of the crane is not allowed to be too large.

If the site conditions are poor and the soil is soft, although there are walkway slabs under the crawler crane, the soil quality will deteriorate after rain. Becoming softer, in order to prevent the crawler crane from tipping during walking and hoisting, other machinery must be provided on site to level and compact again to avoid accidents.

Preventing falls from high altitudes

All on-site construction workers should wear safety helmets, and those working at heights should wear safety belts and wear them high and low, and fasten them

In a safe and reliable place, on-site workers should wear non-slip shoes.

The hoisting work area should be clearly marked and designated with dedicated personnel to guard. Non-hoisting on-site workers are strictly prohibited from entering. When the crane is working, the lifting arm should not be lowered. It is strictly prohibited to stand on people, and it is strictly forbidden to allow people to stay within the swing radius of the crane's boom.

Ladders and hoisting operating platforms used for climbing should be secure. When the crane moves the operating platform, it is strictly prohibited to stand on it.

< p> When hoisting, high-altitude workers should stand on operating platforms, hanging baskets, and ladders. When hoisting steel beams, add safety protection brackets on the top strings, and pull safety wire ropes above people's work to facilitate construction workers on the top strings of the beams. It can be operated safely, and it is strictly prohibited to walk on unfixed components.

After the structural foundation is installed and the purlins are installed in place, the upper string safety brackets of the beams need to be removed. Before removing the installation brackets, adjust the beams On top of the purlins, pull a brown rope with a diameter of 15mm and a length of 90m from the bottom of the columns on both sides as a safety rope to hang the safety belt. Only then can the safety bracket be removed and the remaining purlins above it installed.

High-altitude operations You must wear safety belts, insulated soft-soled shoes, and take safety measures.

Before it is safe to walk, the roof panels must be fully connected to the purlins, with each side connected to other roof panels. Never walk on partially connected or unconnected roof panels. Do not step on the edge ribs of the panels, the folds near the edges of the panels, or within 5 inches of the edge of the unfixed panels.

Single layer Roof panels must not be used as a working platform. People are not allowed to stand on insulation cotton that has no vertical strength.

Once oily substances are found on roof panels, wipe them off immediately to prevent slipping or falling. When working on the edge of a board, workers should always pay attention to prevent dangerous situations and use safety belts, safety nets and handrails.

People's hands and feet must be kept away from moving heavy objects and lifting equipment. People are not allowed to stand under hoisted objects and hoists. < /p>

Prevent falling objects from high altitudes from injuring people

Various tools, bolts, etc. carried by high-altitude workers should be placed in special tool bags. Safety ropes should be hung when transferring objects at high altitudes. , shall not be thrown casually to prevent injury to people.

During hoisting, scattered objects shall not be stacked or hung on the components. Sporadic objects shall be passed up and down in special bags.

Components must be tied Firmly, the lifting point should pass through the center of gravity of the component. When lifting, it should be stable to avoid vibration or swing. The lifting rigging must not be untied before the component is pulled or fixed to prevent the component from falling and injuring people.

When lifting components, the speed should not be too fast, and should not stay at high altitude for too long. It is strictly forbidden to raise or lower suddenly to prevent the components from falling off.

After the components are installed, the connections of each component should be checked. and stable conditions, only when the connection is truly safe and reliable can the hook be loosened and the rope removed.

When hoisting high-altitude docking components, the slip rope must be tied and its direction controlled.

When working on rainy days , necessary anti-slip measures should be taken, and there should be sufficient lighting for night operations.

Specially pointed out that for loose hooks and unloading ropes during mezzanine hoisting, construction workers should stand on a stable and reliable ladder. < /p>

It is strictly prohibited to throw materials downward from high altitude. ;
