The main classification of mobile scaffolding, what are the categories of scaffolding according to i

And mobile scaffolding is not too difficult to find now, I suggest you go here to see mobile scaffolding, the value in use is more perfect, the surface does not need maintenance, and the mobile scaffolding net in other places. The main processing technology is to determine that mobile scaffolding can be found anywhere, which may not be as comprehensive as mobile scaffolding here. So when using mobile scaffolding accessories, you should pay attention to maintenance, so that its service life can be more, mobile scaffolding nets in other places, and the elimination period of use, I suggest you go here to see mobile scaffolding, the surface does not need maintenance.

About finding specific mobile scaffolding, and mobile scaffolding is not too difficult to find now, the cost is high, all of them are galvanized, resulting in many scaffolding accessories are very difficult to use, and the raw materials that need to be used are more complicated. 5 years for surface treatment, the reason is that mobile scaffolding is easy to find.

Determine where you can find mobile scaffolding, every part of the surface, in the market share is relatively large, the reason why the mobile scaffolding here is more complete, the reason why the mobile scaffolding here is more complete, the cost is moderate.

The service life of the integral cold galvanized mobile scaffolding accessories is about 5 years. In actual use, the overall service life is about 5 years. But.

So, even knock out. Regarding finding specific mobile scaffolding, there are many mobile scaffolding accessories because of deformation, and they are not subject to any restrictions in use, and the service life of hot-dip galvanized mobile scaffolding accessories is about 10 years, the reason is that mobile scaffolding is easy to find, and other reasons, it is very close: welding scaffolding accessories and then galvanizing.

Classification of steel pipe scaffolding.

The scaffolding made of steel pipe materials used in China now includes fastener steel pipe scaffolding, bowl buckle steel pipe scaffolding, buckle disc scaffolding, socket steel pipe scaffolding, portal scaffolding, trapezoidal scaffolding, as well as all kinds of scaffolding, hanging scaffolding and other steel pipe material scaffolding. Starting from its material and construction, it can be roughly divided as follows:

1. Operate (operational) scaffolding.

Operational scaffolding is scaffolding that provides working at height conditions for construction operations. Operation scaffolding is further divided into structural work scaffolding (structural scaffolding) and decoration work scaffolding (decoration scaffolding). The standard values of the construction load on the frame deck are specified as 3kn m2 and 3kn m2 respectively.

2. Scaffolding for protection.

Protective scaffolding refers to scaffolding that is only used for safety protection, including various guardrail frames and scaffolding. The standard value of the frame construction (erection) load can be calculated according to 1kn m2.

3. Scaffolding for load-bearing and support.

Scaffolding for load-bearing and support refers to scaffolding used for the operation, storage, support and other bearing purposes of materials, such as receiving platforms, formwork support frames and installation support frames. The construction load of the frame surface is calculated according to the actual use value.

The use is two types of load-bearing scaffolding and construction scaffolding, a temporary construction measure.

Operation, Protection, Load-bearing support.

I know that there are portal scaffolding, steel pipe scaffolding, and I don't know the others very well, or you go to the fast rental network to take a look, there are many scaffolding companies, you should find more classification.

Scaffolding Type:According to its erection position, it is divided into external scaffolding.

and the two categories of scaffolding; According to its structural form, it is divided into multi-force rod type, frame type, bridge type, hanging type, lifting type, and tool scaffolding for interlayer operation, and the materials used are wood, bamboo, steel pipe scaffolding, steel pipe scaffolding is the most widely used in China, has the largest number of erection tools, generally using A3 electric welded steel pipe, its condition, development and improvement of China's construction scaffolding technology will have a decisive impact.

Requirements for erecting scaffolding.

1. Pole foundation:

When the scaffold is erected, it is required that the ground at the construction position must be flat and have a certain bearing capacity, and special drainage equipment is set up to ensure that the base meets the standard requirements.

2. Scaffolding and building ties:

At the beginning of the construction, it is necessary to meet the safety standards, and the spacing of the main node between the wall pieces must be controlled within 30 centimeters, and at the same time, it must be set from the ground floor. If the height of the scaffolding exceeds 24 meters, rigid joints should be used.

3. Scaffolding scissor support:

The scissor brace has a horizontal and longitudinal distinction, and the construction needs to be carried out in strict accordance with safety standards, especially the lengthening of the rod, the position of the oblique rod and the connection of the frame. In addition, the distance of the scaffolding pole must also meet the requirements of safety standards.

The main types of scaffolding are fastener scaffolding, portal steel pipe scaffolding, and lifting scaffolding.

Details are as follows:

1. Fastener scaffolding:

Fastener scaffold is a kind of multi-pole scaffold that is widely used at present, and can also be used as scaffolding and full scaffolding.

formwork, etc. There are three commonly used fasteners: rotary fasteners, right-angle fasteners, and butt fasteners.

2. Gantry steel pipe scaffolding:

Gantry steel pipe scaffolding, also known as "scaffolding" and "frame scaffolding", is a popular form of scaffolding in the international civil engineering industry, with a complete range of varieties and more than 70 kinds of accessories.

3. Lifting scaffolding:

Attached lifting scaffold refers to an external scaffold that is erected at a certain height and attached to the engineering structure, relying on its own lifting equipment and devices, which can climb or descend with the engineering structure layer by layer, and has an anti-overturning and anti-falling device.

The attached lifting scaffold is mainly composed of the attached lifting scaffold body structure, the attached bearing, the anti-tilting device, the anti-falling device, the lifting mechanism and the control device.

Compared with the general structure, the working conditions of scaffolding have the following characteristics:

1. The variability of the load is large.

2. The fastener connection node is semi-rigid, and the rigidity of the node is related to the quality of the fastener and the installation quality of the mold, and there is a large variation in the performance of the node.

3. There are initial defects in the scaffolding structure and components, such as the initial bending and corrosion of the rods, the erection size error, and the load eccentricity are large.

4. The connection point with the wall has a large variation in the constraints of the scaffolding. The research on the above problems lacks systematic accumulation and statistical data, and does not have the conditions for independent probability analysis, so the adjustment coefficient of the structural resistance multiplied by less than 1 is passed and the safety factor used in the past is passed.

Perform a calibration determination.

Therefore, the design method adopted in this specification is semi-probabilistic and semi-empirical in nature. It is the basic condition for the design and calculation that the trace scaffold meets the structural requirements specified in this specification.

Introduction: mobile scaffolding is one of the indispensable construction tools in on-site construction, its main role is to solve the transportation between vertical or horizontal, its biggest advantage over fixed scaffolding is that it can be disassembled, so the installation is relatively simple, and its bearing performance is also relatively strong, so many construction sites are used mobile scaffolding. Since the seventies of the last century, this new type of scaffolding has been used in our country.

So next, Tuba Rabbit will tell you about the classification of several mobile scaffolding, Laqing and their respective characteristics!

The first is the scaffold of the fastener code coarse type, the bearing capacity of this scaffold is relatively strong, and because it is more convenient to erect, the fastener between the various parts of the scaffold is easier to disassemble, and it is also relatively easy to adjust, so it can be applied to the construction of various buildings. And its economic cost is relatively low, and its cost per investment is relatively low. Of course, because it is a fastener-type scaffolding, it has a lot of deductions, so you must keep it carefully, otherwise it will be easily lost.

There is also the problem of paying attention to the center of gravity at the node, otherwise it is easy to have some safety hazards if the construction is not good.

The second is portal scaffolding. The structure of portal scaffolding is more reasonable than that of fastener design, and it is safer to build than Chizhen. However, it is the least flexible in centralized scaffolding, it is like a rectangular board, as long as one of the components is moved, the other parts will also be affected, so the overall cost is still relatively expensive.

It is used as long as it is used on a movable workbench.

The third type is the bowl-type steel pipe scaffolding, which is the most used scaffolding on the construction site today. Because it is more powerful, its parts of the node are more flexible, so the size of each part can be changed according to the requirements of specific site construction, and the shape and style can also be adjusted accordingly. In addition, the bowl buckle type is also relatively safe and reliable, because the pressure of the bowl buckle is considered in the design, so the friction is just right when designing, and it will not cause some accidents due to insufficient force during construction.

The fourth type is buckle scaffolding, which has strong flexibility and the ability to maneuver. So it can adjust the scope of the entire scaffold according to the size of the construction area. And it is also possible to build scaffolding of different shapes and specifications according to the needs of construction.

Finally, it is also more convenient in terms of transportation and storage, because it is relatively small, so it can pass through narrow pipes.

As we all know, the houses we live in are getting higher and higher. People generally build boards high in the air to facilitate the construction of buildings. But in the lower floors, for example, the height of the first and second floors, people usually use a more convenient item, that is, mobile scaffolding, this kind of scaffolding is very convenient in use, but it also has different classifications, each classification has different characteristics and **, let us understand it in detail.

Main classifications and features of mobile scaffolding:

1. Fastener-type foot skin.

Advantages: (1) Large bearing capacity. When the geometric size and structure of the scaffold meet the relevant requirements of the code, under normal circumstances, the bearing capacity of the single-tube column of the scaffold can be slowed down to 15kn 35kn (, design value).

2) Easy to assemble and disassemble, flexible to erect. Because the length of the steel pipe is easy to adjust and the fasteners are easy to connect, it can be adapted to the scaffolding of buildings and structures of various planes and elevations. (3) Relatively economical.

The processing is simple, and the one-time investment cost is low; If the geometric dimensions of the scaffold are carefully designed, and attention is paid to improving the utilization rate of the steel pipe around the fuel pin, the amount of material can also achieve better economic results. The fastener steel pipe frame is equivalent to about 15 kilograms of steel per square meter of construction.

2. Bowl-buckle steel pipe scaffolding.

Advantages: (1) Multi-functional: According to the specific construction requirements, it can form a variety of construction equipment with various functions such as single and double row scaffolding, support frame, support column, material lifting frame, climbing scaffolding, cantilever frame and other functions according to specific construction requirements.

It can also be used to erect facilities sheds, material sheds, lighthouses and other structures. It is especially suitable for erecting curved scaffolding and heavy-duty support frames. (2) Efficacy:

The longest of the commonly used members is 3130mm, which is heavy. The speed of the whole frame is 3 5 times faster than the conventional, the dismantling is fast and labor-saving, and the workers can complete all the operations with a hammer, which avoids many inconveniences caused by bolt operation.

Moving scaffolding's **:

Scaffolding Type 95 Trapezoidal Frame Movable Mobile Frame Thickened Gear Pedal Load-bearing Larger.

Hot-dip galvanized extra-heavy thickened scaffolding trapezoidal movable scaffolding mobile scaffolding.

Heavy-duty thickened scaffolding trapezoidal scaffolding mobile scaffolding.

Thick weight 88 kg set ladder type mobile scaffolding.

Galvanized movable scaffolding, moving wheels, ladders, doors, scaffolding.

Trapezoidal scaffolding movable scaffolding moves.

Find the same style to find similar thickened trapezoidal scaffolding to move the scaffolding.

There is no perfect object in the world, even if people are, of course, the items are the same, with special advantages, there will be disadvantages, let's talk about the bowl buckle steel pipe scaffolding, this kind of scaffolding is more expensive, and the shaping rod of the crossbar will be the size of the frame has certain limitations. Fastener-type scaffolding also has disadvantages, such as the impact of fastener nodes will be directly related to the operation of workers. Fasteners are easy to lose, etc., so everyone should pay attention when using them.
