What is the difference between a hard stamped scaffolding steel pipe and a non hard stamped scaffold

The outer scaffold does hard protection, and the two-step frame that does it on the outer frame begins.

There are clear provisions for laying hard protection on the first layer of the outer frame, and the rods are specified as follows:

1. All steel pipes on the scaffold are painted yellow;

2. The protruding end of the scaffold façade crossbar shall be unified, and shall not be greater than 10 cm;

3. The scissor brace on the scaffold is fully erected, continuously arranged, from the bottom to the top, and the herringbone brace is strictly prohibited, and when the height of the scaffold meets the height of a pair of scissor braces, it is erected with the angle as the starting point;

4. The spacing of scaffold poles is meters, each pole must stand on the channel steel, the step distance is meters, and the row distance shall not be greater than 70 cm;

5. A pole with a spacing of 40 cm is arranged on both sides of the scaffold big angle pole, which is arranged in a tic-tac-toe shape, and a retaining rod must be vertically arranged at the big angle, and both sides of the unloading platform on the scaffold are double poles;

6. The connecting wall rod is marked with red paint, and the two spans are set together, all of which are made of rigid horizontal tie knots, and the main contact point connected to the outer protective frame shall not be greater than 30 cm and the inner and outer rows are connected;

7. The spacing of the small crossbars shall not be greater than 60 cm;

8. The distance between the outer protective frame and the wall is between 30 cm and 40 cm;

9. The lap point of the adjacent pole of the outer protective frame shall not be in the section of the same step;

10. The outer protective frame must be more than one meter higher than the working surface.

We generally use fastener type scaffolding, steel pipe diameter 48, wall thickness.

There are many people who don't know what the proportion of steel pipe and steel plate stamping fasteners in the construction of steel pipe scaffolding is, so let Zhuo Xuan people tell you this problem: Generally, there are 200 fasteners per ton of steel pipe, and fasteners are generally divided into three types: right-angle fasteners, connecting fasteners, and rotary fasteners.

Their ratio here is: 8:1:

Scaffolding Pipe Introduction:

Scaffolding pipes are the name given to the materials used to build scaffolding, because most scaffolding uses tubular pipes such as bamboo or steel pipes. Moso bamboo and other bamboo scaffolding pipes have been used for a long time, but due to their lack of safety and durability, they are now only used in the construction of small buildings such as self-occupied buildings in rural and backward urban areas. In modern building construction, the most commonly used type of scaffolding pipe is steel pipe pipe, because the erection of scaffolding should not only meet the needs of workers, but also meet the stable and durable characteristics of scaffolding, so strong and hard steel pipe is the best choice.

The selected steel pipe is generally required to have a smooth surface, no cracks, no bending, not easy to rust, and meet the relevant national material standards.

The commonly used scaffolding steel pipe for construction is 48* specification. Length: 6 meters, 3 meters, 2 meters, 1 meter.

The standard length of the scaffolding steel pipe is 6 meters, and there are 6 meters, 3 meters, 2 meters, meters, 1 meter, etc. for ease of use.

According to the actual situation of the construction site, the steel pipes used are 1 meter, 2 meters, 3 meters, 4 meters, and 6 meters, and 6 meters is the longest of these specifications.

The length is different according to different occasions of use. The general length is between 1 meter and 6 meters.

The specifications of scaffolding steel pipes are as follows:

The steel pipe should be used in the national standard GB T13793 or GB T3091 specified in the Q235 ordinary steel pipe, the model should be calculated according to the scheme of 48), the material should provide a product certificate and acceptance, qualified before it can be put into use.

The commonly used scaffolding steel pipe for construction is 48* specification. Length: 6 meters, 3 meters, 2 meters, 1 meter.

GJ 130-2011 "Safety Technical Code for Fastener-type Steel Pipe Scaffolding for Building Construction" stipulates that the nominal outer diameter of steel pipe is and the wall thickness is.

In actual use, the outer diameter of the steel pipe basically meets the requirements of the specification, but the wall thickness is different.

Generally, there are two kinds, one is 48mm outer diameter and wall thickness; The other has an outer diameter of 51mm and a wall thickness of 3mm. According to its location and function, it can be divided into vertical rods, horizontal rods, sweeping rods, scissor braces, etc.

According to the "Safety Technical Code for Fastener Steel Pipe Scaffolding for Building Construction" JGJ 130-2011.

1. The scaffolding steel pipe shall adopt the Q235 ordinary steel pipe specified in the current national standard "longitudinal welded steel pipe" GB T13793 or "welded steel pipe for low-pressure fluid transportation" GB T3091; The steel quality of the steel pipe should meet the provisions of the Q235 grade steel in the current national standard "Carbon Structural Steel" GB T700.

2. The steel pipe of the scaffold should be made of steel pipe. The maximum mass of each steel pipe should not be greater than.

There are many specifications of scaffolding steel pipes, which can be divided into several sizes according to their diameter: There are also many specifications for length:

1 to 6 meters and a half meters a size; It can be processed according to customer specifications. The thickness is generally millimeters, and the diameter is 48 millimeters. The surface is generally not treated, and individual anti-rust paint is applied.

The material of the scaffolding steel pipe is: Q195, Q215 or Q235. The implementation standards for scaffolding steel pipes are:

SY T5768-95 and GB T3091-2001. The weight of the national standard shelf pipe per meter is tons, and the actual weight of the whole pipe: the length of the steel pipe.

Different types of engineering construction use scaffolding and formwork support.

1. The standard size is.

According to the diameter, it can be divided into: the length is 1 to 6 meters and a half meters, the thickness is generally millimeters, and the diameter is 48 millimeters.

2. Advantages. 1) The bearing capacity is large. When the geometric size and structure of the scaffold meet the relevant requirements of the specification, under normal circumstances, the bearing capacity of the single-tube column of the scaffold can reach 15kn 35kn (1 5tf 3 5tf, 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 turnover and utilization rate of steel pipes, the amount of materials can also achieve better economic results. The fastener steel pipe frame is equivalent to about 15 kilograms of steel per square meter of construction.

3. Disadvantages. 1) The fastener (especially its screw) is easy to lose;

2) The members at the node are eccentrically connected, and the load and internal force are transmitted by the anti-sliding force, thus reducing their bearing capacity.

3) The connection quality of the fastener node is significantly affected by the quality of the fastener itself and the operation of the worker.

The standard size of scaffolding steel pipe is one inch and two as standard.

The fastener-type steel pipe scaffold commonly used in China is made of cast iron, and its mechanical properties should conform to the "Steel Pipe Scaffolding Fastener-type Steel Pipe Scaffolding" (GB15831-2006), and the material is not less than KT330-08. It is also required that the fastener-type steel pipe scaffold system has few parts, simple installation, and easy disassembly. In addition to cast iron fastener-type steel pipe scaffolding, there are also steel fastener-type steel pipe scaffolding.

Steel fastener type steel pipe scaffold is generally divided into cast steel fastener type steel pipe scaffold and steel plate stamping, hydraulic fastener type steel pipe scaffolding, cast steel fastener type steel pipe scaffold production process is roughly the same as cast iron, while steel plate stamping, hydraulic fastener type steel pipe scaffold is made of steel plate through stamping, hydraulic technology pressing. The steel fastener type steel pipe scaffold has superior performance in various aspects, such as breaking resistance, slip resistance, deformation resistance, detachment resistance, rust resistance, etc.

The classification method is not clear, the fastener type steel pipe scaffold is divided according to the transmission mode of force, and the last two are classified according to the structural form.

Fastener type steel pipe scaffolding.

Generally, it is composed of steel pipe rods, fasteners, bases, scaffolding, safety nets, etc.

Steel pipe members: generally there are two kinds, one with an outer diameter of 48mm and a wall thickness; The other has an outer diameter of 51mm and a wall thickness of 3mm. According to its location and function, it can be divided into vertical rod, horizontal rod, sweeping rod, etc.

Fastener: Fastener is the connection between the steel pipe and the steel pipe, and there are three forms, namely right-angle fastener, rotary fastener, butt fastener Right-angle fastener: used for the connection of two vertically intersecting steel pipes, it relies on the friction between the fastener and the steel pipe to transfer the load.

Rotating fastener: used for the connection of two intersecting steel pipes at any angle.

Butt fastener: used for the connection of two steel pipes with butt joints.

Base and backing plate: It is a cushion seat set up at the bottom of the upright pole, pay attention to the difference between the base and the backing plate, the base is generally welded with steel plate and steel pipe, and the base is generally placed on the backing plate, and the backing plate can be a wooden board or a steel plate.

Scaffolding (see ** below), safety net (without explanation, this one is simple).

Here are some key incomprehensible terms.

Main node: refers to the fastening point at the junction of the vertical rod, longitudinal and transverse horizontal rods.

Sweeping rod: A horizontal rod close to the ground and connected to the root of the pole.

Vertical distance (or span) of the pole: the longitudinal spacing of the scaffold pole.

Vertical pole step distance (or step): The distance between the axis of the upper and lower horizontal rods. See.

The on-site situation where the floor-to-ceiling type is only erected is erected from the ground. The natural foundation of the ground is load-bearing.

The cantilevered type is the cantilever beam or cantilever frame bearing the load;

Fastener type refers to the material. It is divided into bowl buckle type, fastener type, and door frame.
