Aluminum alloy scaffold safety operation precautions

As the technology is constantly advanced and developed, aluminum alloy materials widely used in high-intensity use are widely used in today's production and life.application.

The fast-mounted aluminum alloy scaffold is divided into several, mainly according to its width.

1. Single width aluminum alloy

2. Double wide aluminum alloy

According to the type of ladder of the scaffold, it can be divided into:

1.Stranglad frame

2. Scooter Scooter

3. Suspension Scaffolding

Based on the scene and function classification, it is more complicated or exhausted. It can be divided into Construction scaffolding, maintenance and maintenance scaffolding, cleanup installation scaffolding, etc.

The main features of the portable fast-moving scaffold have the following advantages:

1. Aluminum alloyHigh material intensity, high payload, safe and reliable.

2.Light material, the weight is about about other traditional steel scaffolding1/3.

3.Easy to build, fast installation, speed is ordinary steel hornsMore than 10 times. For example, it is necessary to build a 20-meter steel scaffolding, more than 6 hours can be completed. Aluminum alloy fast-built scaffolding has the same height, only 3 people can be completed and do not require any other special tools.

4.Easy to move, reduce the second disassembly work within the construction site.

5.Can be used indoors and outsourcing, can be built in any working terrain, the floor is small,Do not damage ground; no noise.

Portable aluminum alloy scaffolding in China

The time to use the aluminum alloy scaffold in China is still relatively short. Mainly applied to electricity, petrochemical, Aerospace and other enterprises. These companies are relatively comparable to the use and management of equipment.More stable, can be used in accordance with the safe use regulations provided by the supplier, so use The effect is very good, affected by the three aspects of production, sales and use.

With the advantages of aluminum alloy, the advantages of the cracks of the aluminum alloy are gradually recognized by the people in various industries.Enterprise and business units, hotel hotels and cleaning cleaning are also widely used.

However, due to the training of the supplier's training, plus the flow of the user is fasterEqual factors, it is inevitable that there are some safety hazards in the process of use.

Below, the safety construction process and precautions for the aluminum alloy feet are described below:

FIRST, Security check

Before building and using a scaffolding, please check the following accuracy:

1.Check all components to ensure that each parts are intact, and the defect should be supplemented or replaced in time;

2.Soldering point check: Ensure that all welding points should not be sold:

3.Pipe examination: All pipes do not have cracks; significant dents produced without squeezing or bumps. Everything exceed5mm Dissolving pipes are not available;

4.The thread of the adjustable leg should be cleaned and lubricated.

SECOND, installation steps

To ensure maximum security during the construction and use of scaffolding, follow these steps Make installation:

1.Build

•Check all components on-site (see product configuration list);

•Ensure that the ground of building and moving scaffolding can provide sufficiently stable and sturdy support;

•The overall load of each set of scaffoldes is750kg,Single platform board maximum load is250kg:

•Only from the scaffolding side in the process of construction and use;

•Do not use any material in the platform or other increased object to increase the working height.

2.Improve

•At the time of construction, the increase in scaffolding components should use the intensity of reliable materials, such as dedicated hoisting. Bracket, crude rope, etc., and use seat belts;

•According to the regulations, external support or weight is required in a non-standard or large scaffolding;

•Use weight at the bottom to prevent large scaffolding;

•The use of external support can refer to the configuration table;

•Please consult your supplier (or vendor) when you use the outside environment, or in the supply Under the guidance of commercial (or manufacturers), the weight should be placed in overload support using solid materials. On the leg, the weight is safe to place to prevent accidental dismount.

3.mobile

•Scaffolding can only push human power to push the underlying level of the entire shelf:

•When moving, pay attention to electrical appliances that are running nearby, especially air pipelines, etc .;

•When moving, someone or other items are not allowed on the scaffold to prevent falter;

•Be careful when moving on rugged ground or slopes, pay attention to the placement of your foot. direction;

•When the wall is supported, the outer support can only leave enough distance; to avoid obstacles, move the height of the moving scaffold should not exceed the minimum bottom size2.5Multiplier.

For example: the height of non-mobile scaffolding9 meters, the mobile scaffolding is reduced to7.5Meter.

Moving scaffolding should pay attention to:

•Everyone must leave the scaffold and clean up all debris under the rack;

• Construction personnel should push scaffolding at the bottom of the scaffolding:

•Do not pull the top of the scaffold;

•When you stop moving scaffolding, all casters must be locked, while all other attachments must be parallel. Place the ground.

4.use

Be alert to the wind, gust of wind. Wind speed exceeds7.9m/ Second (wind is greater than 4), stop the scaffolding operation; wind speed exceeds13.8m When the fan is larger than 6 levels, the scaffolding is brought on other solid structure; if it is more than 18 m / sec (wind is greater than eight levels), the scaffold should be removed in advance. Pay attention to the whirlwind that can be caused by buildings.

Wind effect reference table:

Wind level	name	Wind speed(m / s)	Terrestrial object	Sea surface waves	Wave high (rice)
0	No wind	0. 0-0.2	Cigarette	calm	0
1	light air	0. 3-1.5	Smoke	Microwave peak without foam	0.1
2	Light wind	1. 6-3.3	Feel wind	Small bee is not broken	0.2
3	breeze	3. 4-5.4	Flag	Small wave peak rupture	0.6
4	Harbor	5.5-7.9	Purge dust	Xiaolang White Peak	1
5	Strong wind	8. 0-10.7	Small tree swing	Slogan	2
6	Gale	10.8-13.8	Radio	Large waves to a foam	3
7	blast	13. 9-17.1	Difficult footage	Broken peak white	•1
8	Wind	17. 2-20.7	Break the branch	Survival	5.5

•When working, there is no high voltage cable around the homework (see Schedule) and other impact Full obstacle.

Use a safe distance reference table:

Voltage circumference (V)	Minimum safe distance(m)
0-300	Avoid contact
300-50000	3
50000-200000	4.6
200000-350000	6
350000-500000	7.6
500000-750000	10.6
750000-1000000	13.7

•It is not possible to abuse components, especially those that are bad or uncontrollable;

•Use a rope to increase or decentralize components, tools and materials, should be carried out on the foot of the scaffolding base. I don't think the platform and the overload of the wholeExceed the standard.

•Building a good scaffold is a work platform, don't use it as a channel.

•Level force(If using the power tool) can produce instability.

•A strait should be used when frequently carrying tools or materials.

THIRD, Scaffold outdoor construction instructions

1. Aluminum alloyScaffolding height scale-room

In the room, the maximum height of the platform is its width3.5Double, such as the width of the platform1.35Rice,

Height cannot be higher than4.7 meters.

2. ExpressScaffolding height scale- Outdoor wind

When there is no wind outdoor, the maximum height of the platform is its width.3 times, such as the width of the platform1.35M, its height cannot be higher than4.1 meter.

Note: Outdoor scaffolding is more strictly limited to its height, cannot be higher than3 times

3.Supported device

In the room, the height of the workbench is its width3.5Multiple, such as deviceST1Standard support, wide Increase3.47Mi, so its height can be increased to12.15 meters.

4.Outer launch device

At outdoor, the height of the workbench is its width3 times,For example置ST2Large support, its width Increasing5.83Mi, so its height can be increased to17.5Meter.

5.Effect of foreign factors

Maximum influencing factors: horizontal force, wind, external force

Ground conditions: obstacles;

The role of external force.

When the construction of the construction worker is drilled on the wall with the electric drill, the effort will produce and The opposite reaction force. Therefore, the scaffold should reduce its use height accordingly.

Please pay attention to the ground status when construction, first check the ground and related positions:

•The ground must be flat

•There is no step (except special requirements)

•No gap

•Clean all garbage

•Pay attention to high dangerous objects

•Height of the ceiling

•beam

•Hang

•Wire, etc.
