What are the components of various types of scaffolding?

Steel pipe fastener type scaffolding.

With its excellent stability and strong overall stiffness, it has now become the most common scaffolding on construction sites, which is supported by various stressed members, large and small crossbars, vertical rods, and scissors.

tie points, etc. Large crossbar: Because the transverse structure of the outer frame itself is a single-span structure with a huge difference in the height span ratio, if it is difficult to ensure the overall stability of the structure by relying on the transverse piece alone, and prevent the scaffold from overturning after compression or under the action of horizontal force, the specification requires that a large crossbar be set up to improve the overall reliability of the outer frame.

Small crossbar: The small crossbar is the main member that constitutes the transverse frame of the outer frame, is an important part of the scaffold to directly bear and transmit the vertical load, and is the main body of force and force transmission. Scissor braces:

Because the outer frame is a square frame composed of upright rods and longitudinal and transverse horizontal rods, its structure itself has congenital deficiencies, and it is easy to produce longitudinal deformation, in order to strengthen the overall stiffness of the longitudinal façade of the outer frame, so that it forms a geometrically stable framework, so as to prevent the bottom displacement of the upright rod under the action of eccentric moment.

Tie point: Tie point is a constraint point that effectively transfers the load and other horizontal loads borne by the outer frame to the main structure and restricts the vertical free deformation (swing) of the scaffold. Scaffolding is roughly divided into full-hall scaffolding; Multi-pole scaffolding portal scaffolding.

and pole-type scaffolding. Full house of scaffolding.

It is mainly used for the decoration construction of single-storey factories, exhibition halls, gymnasiums and other buildings with high floors and large bays. It is composed of upright rods, cross bars, diagonal braces, scissor braces, etc. Multi-pole scaffolding is mainly composed of horizontal rods, vertical rods, oblique rods, nodes, adjusting bolts, and bottom plates.

Gantry scaffolding is based on gantry.

Cross supports, connecting rods, buckle-type scaffolding boards or horizontal frames, lock arms, etc. form the basic structure, and then set up horizontal reinforcement rods, scissor supports, and sweeping rods.

Sealing rods, brackets and bases, and using connecting wall pieces.

A standardized steel pipe scaffold connected to the main structure of the building. Gantry steel pipe scaffolding can be used not only as external scaffolding, but also as internal scaffolding or full scaffolding. The vertical pole scaffold is composed of a longitudinal and transverse sweeping rod, a vertical pole, a large crossbar, a small crossbar, a scissor brace, a wall piece, a scaffold board, a foot guard, and a safety net.

Mobile scaffolding is mainly composed of main frame, horizontal frame, cross diagonal brace, scaffold board, adjustable base, etc. The cross tie rod, also known as the diagonal tie rod, is a cross-type tie rod that connects two sets of masts longitudinally. The flattened parts at both ends of the rod are punched with pin holes, and are locked firmly with the locking pins on the mast upright rods when assembled.

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. Scaffolding of a single specification steel pipe. It uses only one specification of steel pipes, such as fastener-type steel pipe scaffolding, and only 48 electric welded steel pipes.

Scaffolding with a combination of steel pipes of various specifications. It is constructed of more than two different specifications of steel pipes, such as portal scaffolding. Scaffolding based on steel pipes.

That is, the scaffold composed of steel pipes and supplemented by other steel rods, such as the scaffold with channel steel roof or base, and the scaffold with connecting steel plates.

A kind of hanging tool scaffold, it is characterized in that: the upper part of the double-row boom type scaffold that is composed of a boom, a large cross bar and a connector is connected with a horizontal beam, the top of the horizontal beam is connected with a fixed arm, a lifting ring is installed on the fixed arm, the lifting ring is connected with the outer end of the boom through a fixed cable, the boom passes through the window hole, the door hole or the balcony hole, its inner end is installed and fixed in the building, the outer end of the boom is also connected with one end of the adjustable length tie rod, and the other end of the adjustable length tie rod is fixed on the floor slab through the screw rod through the plate; Two horizontal support legs hinged together are installed on both sides of one end of the fixed arm close to the wall; The inner side of the scaffold is tied to the building by connecting wall pieces. The utility model discloses with less material, saves manpower, and operates safely, and is convenient and quick.

During the decoration construction phase, the scaffolding was instead suspended from the roof and descended from floor to floor.

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 is not the same as the ladder that people usually say, and the former is closely related to the safety of construction personnel, so when building or choosing, you should choose the right one, and the types of scaffolding are divided into many kinds. Scaffolding is not the same as the ladder that people usually say, and the former is closely related to the safety of construction personnel, so when building or choosing, you should choose the right one, the types of scaffolding are divided into many kinds, and different classification methods are not the same, how many types of scaffolding are divided into? How is scaffolding classified?

Take a look at the introduction below.

There are several types of scaffolding

Scaffolding is divided into steel pipe fastener scaffolding.

Bowl buckle steel pipe scaffolding, disc buckle scaffolding.

1. Steel pipe 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. Bowl-buckle steel pipe scaffolding.

It is a multi-functional tool-type scaffolding, which is composed of main components, auxiliary components and special components. The whole system is divided into 23 categories and 53 medium specifications. Uses: single and double row scaffolding, support frames, support columns, material hoisting frames, cantilever scaffolding.

Climbing scaffolding, etc.

3. Disc buckle scaffolding.

Disc buckle scaffolding, also known as chrysanthemum disc scaffolding system, disc type multi-function scaffolding, is a bowl buckle scaffolding.

Later upcycles. It is mainly used for lighting racks and background racks for large-scale concerts.

How is scaffolding classified?

1. If it is classified according to its use, it can be divided into three types: operation scaffolding, including structural operation scaffolding and decorative operation scaffolding; Scaffolding for protection, mainly used for safety protection; Load-bearing and supporting scaffolding, mainly used for formwork support.

2. If it is classified according to the type of erection, it can be divided into single-row scaffolding, double-row scaffolding and full-hall scaffolding.

3. If it is divided according to the material, it can be divided into bamboo, wooden scaffolding and scaffolding erected with wood or bamboo poles; Steel pipe scaffolding, including steel pipe fastener scaffolding, bowl buckle scaffolding, disc buckle scaffolding, portal scaffolding.

4. If it is classified according to the support method, it can be divided into: floor scaffolding, cantilevered scaffolding, wall hanging scaffolding, suspension scaffolding, and attached lifting scaffolding.

How many types of scaffolding are there? How is scaffolding classified? After passing the above content, you must have understood it, in fact, the classification of scaffolding is divided into a lot, in the face of different classifications have different advantages, the application of the field and the effect are also different, when the selection should be combined with the actual needs to choose, so that it will be more appropriate.

Hello. Home expert Yingzi is happy to answer for you. The composition of the scaffolding project mainly includes:

Vertical rods, longitudinal horizontal rods, transverse horizontal rods, longitudinal sweeping rods, transverse sweeping rods, fasteners (right-angle fasteners, rotary fasteners, butt chain old fasteners, anti-slip fasteners), scissor braces (also known as cross braces, cross covers), transverse diagonal braces (also known as transverse diagonal rods, zigzag files), scaffolding, wall pieces (also known as wall point shed bumps, wall rods), bases, etc. Hello, I hope my answer can help you. If you have any questions, please ask me.

Have a great day. If I can help you, you give a like, look forward to your like, dear, thank you.

1. Full scaffolding.

The full scaffolding is composed of upright poles, cross bars, diagonal braces, scissor braces, etc.

2. Portal scaffolding.

This kind of scaffolding is mainly composed of the main frame, the horizontal frame, the cross diagonal brace, the pure reed core scaffolding, the adjustable base, etc.

Scaffolding features:

1. The variability of the load is large;

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

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

4. The constraints of scaffolding are very different at the connection with the wall. The research on the above problems lacks systematic accumulation and statistical data, and there are no conditions for independent probability analysis. Therefore, the adjustment factor multiplied by the value of the structural resistance of less than 1 is correctly calibrated with the safety factor used in the past.

Therefore, the design approach adopted in this specification is semi-probabilistic and semi-empirical in nature. It is the basic condition for design and calculation that the scaffolding meets the construction requirements specified in this code.

Scaffolding is mainly for the construction personnel to work up and down or the perimeter safety net enclosure and high-altitude installation components, etc., to say that the white cong branch is to build a frame, some projects also use scaffolding as a formwork, in addition to the advertising industry, municipal, traffic roads and bridges, mining and other departments are also widely used. Let's take a look at the classification and characteristics of scaffolding.

Classification of scaffolding.

1. Whether it is movable: it is divided into two types: mobile and fixed;

2. Materials: divided into wood, steel and soft ladders;

3. Tower connection form and use purpose:

Formwork support - a shelf erected with scaffolding materials for supporting the formwork.

Single-row scaffolding - referred to as single-row scaffolding, that is, there is only a row of vertical poles, and one end of the transverse horizontal rod rests on the wall.

Double-row scaffolding - referred to as double-row scaffolding, that is, scaffolding composed of two rows of vertical poles and horizontal poles inside and outside.

Decoration scaffolding - used for decoration engineering construction work.

Structural scaffolding - used for masonry and structural engineering construction work.

Cantilever scaffolding - used for equipment installation or maintenance of cantilever operations.

4. Construction nature: divided into construction scaffolding and installation scaffolding.

5. Occlusion size.

Open Zheng You style: scaffolding with only railings and foot guards on the working floor, and no other blocking facilities. Shouting Zheng Pin is a popular scaffolding rental in Tianjin.

Fully enclosed: A scaffold that is enclosed along the outside of the scaffold at full length and height.

Semi-enclosed: scaffolding with 30% and 70% of the sheltered area.

Partial closure: the occlusion area is less than 30%.

6. Miscellaneous. Soft ladder: Hanggan uses short wooden sticks or steel pipes, ropes are tied to the crossbar, fixed at the top when used, and often used during maintenance of catalytic large flues, reactors, regenerators, inclined pipes, etc.

Mobile ladders and baskets: fixed ladders or baskets that can be moved, generally with hooks or slides at the top, and hung in firm parts.

Features of scaffolding:

Different types of engineering construction use scaffolding and formwork support. Most of the bridge support frames use bowl buckle scaffolding, and some use portal scaffolding. Fastener scaffolding is mostly used in the construction of the main structure, and the longitudinal distance of the scaffold pole is generally; The horizontal distance is generally.

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, and there is a large variation in the performance of the joint;

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 factor of the structural resistance multiplied by less than 1 is determined by calibrating the safety factor used in the past. 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 scaffold meets the structural requirements specified in this code.
