Technical analysis of the entire process of steel support construction

Steel support is a commonly used temporary support structure in construction engineering, typically used in industries such as high-rise buildings, underground engineering, and bridge construction. The main function of steel support is to ensure that the building or structure remains stable during construction, preventing collapse or deformation. The correct operation and technical requirements for steel support construction are crucial for the safety and progress of the project. The following is a technical analysis of the entire process of steel support construction:

1. Preparation before construction

Before steel support construction, sufficient preparation work needs to be done to confirm the smooth progress of the construction.

1.1 Engineering Design and Steel Support Scheme

Firstly, steel support design is carried out based on factors such as the scale, type, geological conditions, and construction environment of the project.

. The steel support scheme includes support forms, installation positions, support specifications, and layout methods. The design should comply with the load-bearing requirements and Enron standards of the construction project

Support types: Common support types include diagonal braces, horizontal braces, cross braces, etc. Choosing the appropriate support type can improve construction efficiency

Calculate load: Based on the load situation of the support points, calculate the specifications and quantity of the supports, and confirm that the steel support system has sufficient bearing capacity

1.2 Material Preparation

Before construction, it is necessary to confirm that the required steel support materials are diverse and the material quality meets the design requirements.

. The main materials include steel pipes, steel bars, connecting fasteners, support rods, etc

Steel quality: The steel should comply with relevant standards, and its strength and corrosion resistance (based on actual reports) should be confirmed

Connector inspection: All connectors (such as fasteners, bolts, etc.) should undergo strict quality inspection to confirm that there are no defects

1.3 Construction Team Training

Steel support construction technology requires high standards, and it is necessary to confirm that the construction personnel have focused skills, understand the operation process and safety requirements.

Operation training: including training on basic operation skills such as installation, disassembly, and inspection of steel supports

Anran Education: Conduct construction Anran training to confirm that operators have the ability to respond to unexpected situations that may occur during construction

2. Installation process of steel support

The installation of steel support is the core link of the entire construction process, which needs to be strictly carried out according to the design drawings and construction plan.

2.1 Setting of Support Points

Steel supports need to be set at reasonable positions, usually at key locations on the construction site.

. The support points should be arranged reasonably based on the overall layout of the project, combined with the bearing capacity of the foundation and construction requirements

Positioning and measurement: Use tools such as theodolites and laser rangefinders to confirm the accurate position of the support points

Verticality of support column: Confirm that the support column is vertical to avoid deviation and affect stability

2.2 Assembly of Steel Supports

The assembly of the steel support system should be carried out layer by layer from bottom to top, ensuring that each layer of steel support is firm and excellent.

Connection between uprights and crossbars: Connect the uprights and crossbars with connecting clips to confirm the tightness of the connection.

Installation of support frame: according to the design requirements, the support frame shall be installed one by one, and reinforced by tie rods, slant support and other components

2.3 Temporary Fixing and Adjustment After the initial construction of the support system is completed, temporary fixing is required to confirm the stability of each component and avoid loosening or displacement during subsequent construction

Support adjustment: Confirm the bearing capacity and stability of the steel support by adjusting the length, angle, etc. of the support rod

Check the support frame: Conduct a comprehensive inspection of the installed steel support to confirm that the installation meets the design requirements

3. Monitoring and maintenance of steel supports

During the construction process, steel supports need to be regularly monitored and maintained to confirm that they are always in a safe state.

3.1 Regular Inspection

Mechanical Performance Inspection: Monitor the stress situation of the steel support and confirm that the support force is evenly distributed.

Connection part inspection: Check the connection parts of the support system to confirm that fasteners such as clips and bolts are not loose or damaged

Deformation monitoring: Use tools such as a level to regularly check the verticality and overall stability of the steel support

3.2 Strengthening Maintenance: Reinforcement of Steel Supports: According to the construction progress and changes in the external environment, timely increase support points and adjust support forms

Anti corrosion treatment (based on actual reports): Steel supports may be affected by corrosion during long-term use and require regular inspection and anti-corrosion treatment (based on actual reports), especially in humid or chemically corrosive environments

4. Dismantling and post-processing of steel supports

The dismantling of steel supports should be carried out after the structure is completed and has self stabilizing ability. The dismantling process should be strictly carried out in accordance with the specifications to prevent accidents.

4.1 Disassembly Preparation

Before disassembling, the following items should be confirmed:

Confirm structural stability: Confirm that the building or structure has sufficient stability to independently withstand loads

Dismantling plan: Based on the actual situation of the construction site, develop a detailed dismantling plan to confirm the smoothness and safety of the dismantling process

4.2 Disassembly steps: First, remove the temporary support: Following the principle of dismantling layer by layer from top to bottom, remove the steel support on the top layer first

Demolition layer by layer: After removing each layer of support, the stability of the lower structure should be checked immediately to confirm that there has been no tilting or deformation

4.3 Post processing and Cleaning The dismantled steel support materials should be cleaned, inspected, and maintained for use in the next construction

Material recycling and maintenance: Clean and inspect the steel support materials to confirm that there are no rusting, deformation, or other issues, carry out maintenance work, and extend their service life

On site cleaning: After the dismantling is completed, the construction site should be thoroughly cleaned to confirm that there are no residues or equipment, and to protect the safety of the construction environment

5. Construction precautions

During the steel support construction process, special attention should be paid to the following aspects:

Anran Protection: Construction personnel should wear Anran helmets, safety belts, and other protective equipment, and set up Anran warning lines to prevent accidents

Weather impact: In bad weather, construction should be temporarily stopped to avoid strong wind, rainstorm and other weather affecting the construction quality

Strictly follow the specifications for operation: All operations should be carried out strictly in accordance with the design drawings and construction specifications to confirm the quality and safety of the project

Summary: Steel support construction is a complex and technically demanding process that involves various stages from design, installation to disassembly. Each stage requires meticulous planning and strict execution to confirm the safety and effectiveness of the construction. Through technically reasonable construction management and technical protection, the safety of the project can be effectively improved, accidents during the construction process can be avoided, and the project can be confirmed to be completed smoothly on schedule
