Key points of steel support construction technology in engineering

Steel support construction technology is crucial in construction engineering, as it protects the stability of the structure and the safety of the construction process. Steel supports are widely used in industries such as high-rise buildings, underground engineering, and bridge construction, playing a crucial supporting role in engineering construction. The following are the technical points in steel support construction:

1. Steel support design and construction plan

1.1 Design requirements

The design of steel support system is the foundation for protecting construction quality and safety.

. When designing, it is necessary to comprehensively consider construction loads, structural stability, geological conditions, and environmental conditions

Support arrangement: Based on the function, structural form, and construction technology of the building, arrange support points reasonably and confirm that the force on each support point is uniform

Steel selection: Choose high-strength steel that meets the standards, confirm the bearing capacity and stable performance of the support.

. The connecting components of steel supports (such as fasteners, bolts, etc.) need to comply with specifications to confirm the stability of the connection

Load calculation: According to the load requirements of the project, calculate the load of the steel support to confirm that the support system can withstand various loads that may be encountered during construction, including construction loads, wind loads, etc

1.2 Construction Plan

The construction plan should specify the installation sequence, erection method, and dismantling requirements of the supports.

. The plan should arrange the construction and usage of the support system reasonably based on the on-site situation

Construction sequence: Steel supports should be constructed according to the design requirements and construction sequence, usually gradually from the lower level to the current level.

Construction progress: Install steel supports according to the construction schedule to avoid unnecessary delays in the construction progress

2. Key points of steel support construction technology

2.1 Reasonable arrangement of support points

The arrangement of steel supports needs to confirm the stability and safety of the building structure.

Support point setting: Based on the structural stress analysis, select appropriate support points for support arrangement. Support points should be arranged at key locations of the building, such as the junction of walls and weak structural areas

Selection of support mode: the support mode should be compatible with the structural form of the building. Common support modes include slant support, horizontal bracing, cross bracing, etc. The choice of support form should be determined based on the load requirements of the building, construction conditions, and the feasibility of the support space

2.2 Connection and installation of supporting structures

The connection and installation of steel support systems are key steps in confirming the safety of construction.

The use of connectors: Steel pipe support systems typically connect support rods to other components through fasteners, bolts, and other connectors. The selection of connectors should meet the standards, confirm that the connection is firm and not loose

Installation of support rods: The installation of support rods should protect their tight contact with the building structure to prevent loosening from affecting the support effect. The upright pole of the support rod should be vertical, the horizontal pole should be parallel, and the angle of the diagonal pole should be confirmed to meet the design requirements

2.3 Stability and Stability of Supporting Structures

Confirming the stability and stability of steel supporting structures is important during construction, especially during the erection process, as the stability of the supporting system is crucial to the safety of the construction.

Verticality inspection: Use a level or laser verticalizer to check the verticality of the steel support system, confirm the verticality of the uprights, and prevent tilting

Tightening of support rod: The support rod should be tightened in place to confirm the even distribution of support force.

. Use one-on-one tools to tighten bolts to avoid loosening

2.4 Temporary fixation and adjustment

After the initial construction of the support system is completed, temporary fixation and necessary adjustments need to be made to confirm the stability of the steel support system.

Temporary fixation: During the construction of the support system, temporary fixation measures such as temporary support frames should be used to ensure that the support frames do not shift or tilt

Adjustment and Calibration: After installation, the support structure should be fine tuned to ensure that all support points are evenly stressed and that the height and angle of all support components meet the design requirements

3. Safety points in steel support construction

3.1 Operation safety

During the construction process, it is necessary to pay attention to the safety of the operation and confirm the safety of the construction personnel.

Personnel protection: Construction personnel need to wear safety helmets, safety belts, gloves and other protective equipment, especially when working at heights, to ensure that personnel are safe

Anran protective railing: Install Anran protective railings on scaffolding, platforms, and other areas to prevent construction personnel from falling

Construction area enclosure: Set up warning lines around the steel support construction area to prevent unrelated personnel from entering the construction site

3.2 Construction Monitoring and Inspection During the construction process, routine inspections and monitoring should be carried out to confirm that the steel support system is always in a safe state

Mechanical monitoring: Regularly check the force situation of the support system to confirm that the force on the support is uniform and there is no overload phenomenon

Connection inspection: Check the connection parts of the steel support system to confirm that the fasteners, bolts, etc. are not loose

Deformation monitoring: Use tools such as level gauges and verticals to regularly check the verticality and levelness of the steel support, and confirm that the support structure is not deformed

4. Maintenance and dismantling of steel supports after construction

4.1 Regular inspection and maintenance

After construction is completed, the steel support system needs to be regularly inspected and maintained to confirm its long-term safety.

Regular inspection: Regularly inspect the installed steel supports, especially the fixing of connection parts, support rods, tension rods, and other components

Corrosion prevention (based on actual reports) maintenance: Steel support materials should be regularly treated with corrosion prevention (based on actual reports), especially in humid and highly corrosive environments, to extend their service life

4.2 Disassembly Requirements The dismantling of steel supports should be carried out according to the progress of the project and the completion of the structure. Special attention should be paid to the following items during dismantling:

Dismantling sequence: The support system should be gradually dismantled from top to bottom and from outside to inside to confirm the stability of the construction structure

Safety measures during disassembly: During the disassembly process, it is necessary to confirm that the safety protection on site is in place to avoid accidents during the disassembly process

5. Summary

Steel support construction technology is a crucial part of construction engineering, and its design, installation, monitoring, dismantling, and other aspects are directly related to the safety and construction efficiency of the project.

. Through technically reasonable support layout, construction management, and safety protection, it is possible to confirm the smooth progress of the project and minimize safety risks during the construction process. Mastering the key points of steel support construction technology is an important protection for engineering quality and safety
