What are the general considerations for construction engineering scaffolding

1) The above-mentioned scaffold should be reliably connected with the building by rigid wall pieces, and set up according to 3 steps and 3 spans.

2) It should be focused on checking: the setting and connection of rods, and whether the structure of connecting wall pieces, supports, door trusses, etc. meets the requirements; Whether there is water accumulation in the foundation, whether the base is loose, and whether the pole is suspended; whether the fastener bolts are loose; Whether the deviation between the settlement of the vertical rod and the verticality of the scaffold with a height of more than 24m meets the requirements of the technical specifications; Whether the safety protection measures of the frame meet the requirements; Whether there is an overload of use, etc.

3) The construction plan, pole foundation, frame body and building structure tie, rod spacing and scissor support, scaffold board and protective railing, disclosure and acceptance 6 items in the "Floor External Scaffolding Inspection and Scoring Form" are guaranteed items. The guarantee item is a one-vote veto item, and when the safety inspection score is implemented, when one of the guarantee items in the checklist is not scored or the subtotal score of the guarantee item is less than 40 points, the inspection score sheet shall not be scored.

4) The main forms of safety inspection can generally be divided into regular safety inspection, regular safety inspection, seasonal safety inspection, holiday safety inspection, start-up and resumption safety inspection, professional safety inspection and equipment and facilities safety acceptance inspection.

What information should be done in scaffolding during construction! Hello, glad to answer for you. The information to be done for scaffolding in construction is:

When erecting scaffolding, it is necessary to scaffold the special plan for the sedan car frame (there must be specifications, calculations, thunderbolts, etc.), steel spring sheds, deduction of test reports, expert demonstration (such as the project belongs to the scope of the "construction quality 2009 No. 87" "safety management measures for sub-projects with greater risk", this demonstration needs to be consulted specifically in the "construction quality and J 2009 No. 87") construction stage documents: 1, scaffolding acceptance record 2, inspection record (daily) 3, fasteners, steel pipes, section steel, Embedded parts (if the embedded parts are made by themselves, raw material certificate is required), type certificate (each batch), I hope mine can help you! Do you have any other questions?

Dear, hello, I am glad to send a hand to answer for you: what does the scaffolding project include A: Dear, hello, the composition of the scaffolding project mainly includes:

Upright poles, longitudinal horizontal rods, transverse horizontal rods, longitudinal sweeping rods, transverse sweeping rods, fasteners (right-angle fasteners, rotary fasteners, butt 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 boards, wall pieces (also known as wall points, wall rods), bases, etc. Thank you for your patience. The above is all my reply, if you are satisfied with my service, please give a thumbs up, and then I wish you all the best!

Peace and joy! <>

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 scaffold structure and components, such as the initial bending and corrosion of the rods, the erection size error, and the load eccentricity.

4. The connection point with the wall has a large variation in the constraints of the scaffolding.

What are the engineering characteristics of scaffolding?

Peculiarity. 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 scaffold structure and components, such as the initial bending and corrosion of the rods, the erection size error, and the load eccentricity.

4. The connection point with the wall is wide, and the constraints on the scaffold vary greatly. 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.

Key points of scaffolding construction material requirements:

1) The selection of steel pipes, the thinnest wall thickness of steel pipes shall not be less than should be no serious corrosion, bending, flattening or cracks); The corrosion depth on the surface of the old steel pipe shall comply with the provisions of the "Safety Technical Code for Fastener-type Steel Pipe Scaffolding for Building Construction" JGJ130-2011. Three steel pipes with serious corrosion shall be extracted, and the most serious part of each rust source shall be transversely cut off for sampling and inspection, and the corrosion depth shall not be used if the corrosion depth exceeds the specified value. In addition, the steel pipe entering the site should also be sampled and retested, and it can be used only after it is qualified.

2) The fastener warranty information should be complete, and the sampling retest should be carried out after entering the site, and the technical performance should meet the provisions of GB15831 of the "Steel Pipe Scaffolding Fasteners".

3) Bamboo scaffolding boards made of moso bamboo or nan bamboo.

4) The safety net adopts dense green net, the flame retardant standard of the safety net implements the national standard, and the flame retardant performance of the safety net is tested for the lighter to ignite the mesh for 12 seconds, and after leaving the first source, the flame retardant and continuous combustion do not exceed 4s. The safety net should be woven with 9mm hemp rope, brown rope and nylon rope, and each net should be able to withstand the impact test of the national standards.

5) The I-beam I20 used for cantilever scaffolding shall be made of the material in accordance with the provisions of the current national standard "Carbon Cable Structural Steel" GB T700 or "Low Alloy High Strength Structural Steel" GB T 1591.

The above is collected and sorted out by Zhongda Consulting.

On the construction site, there are four types of scaffolding that are more common: 1. Scaffolding for decoration engineering operations (referred to as decoration scaffolding): It is a scaffolding set up to meet the decoration construction work.

2. Support and load-bearing scaffolding (referred to as formwork support frame or load-bearing scaffolding): It is a scaffold set up to support the formwork and its load or to meet other load-bearing requirements. 3 Structural engineering operation scaffolding (referred to as structural scaffolding) of Hongcheng Building Materials Service Department in Hongshan District, Wuhan:

It is a scaffolding set up to meet the needs of structural construction operations, also known as masonry scaffolding. 4. Protective scaffolding: including wall-type single-row scaffolding for operation enclosure and passage protection shed, etc., which is a frame set up for construction safety.

If it is a structural scaffolding, it should be a fastener-type steel pipe scaffolding, and if it is a decorative scaffolding, it should be a portal scaffolding!!

Aluminum alloy single-tube scaffolding, decoration and decoration, difficult engineering construction, maintenance and installation, aerial work, etc.

Tangshan Steel Mill Direct Sales 48 Welded Pipe (Shelf Pipe Scaffolding), Specification: 48*; Excellent product quality and reasonable price; And according to customer requirements, anti-rust painting treatment and hot and cold dip galvanizing treatment;

Generally, it can be divided into the following four categories:

1. Structural engineering operation scaffolding (referred to as structural scaffolding): It is designed to meet the needs of structural construction operations.

Scaffolding, also known as masonry scaffolding.

2. Decoration engineering operation scaffolding (referred to as decoration scaffolding): It is set up to meet the decoration construction work.

Scaffold. 3 Support and load-bearing scaffolding (referred to as formwork support frame or load-bearing scaffolding): It is used to support the formwork and its load.

or scaffolding set up to meet other load-bearing requirements.

4. Protective scaffolding: including wall-type single-row scaffolding for operation enclosure and passage protection shed, etc., for construction safety.

Set the shelves.

The construction load and frame width of structural scaffolding are generally greater than that of decoration scaffolding, so in structural engineering.

After the construction is completed, it can be directly used for decoration operations. In the structure and decoration work frame, the worker is carrying out the step frame of the construction work.

This is called the "job layer".
