Precautions for the construction of cast-in-place arch steel formwork.
In building construction, cast-in-place arch steel formwork is a common and important structural form. Its construction is of great significance to ensure the quality and safety of the project. This article will introduce in detail the precautions in the construction process of cast-in-place arch steel formwork to ensure the smooth progress of the construction process.
1. Preparation before construction.
1.Determination of the design scheme: Before construction, a detailed design scheme must be formulated according to the engineering requirements and the actual situation. The design scheme should include the size, shape, material selection and other contents of the arched steel formwork to ensure that the formwork can meet the construction requirements.
2.Material preparation: According to the design plan, prepare the required steel, connectors, support materials, etc. Ensure that the quality of materials meets the requirements of the specification, and avoid substandard construction quality due to material problems.
3.Preparation of the construction site: ensure that the construction site is flat and clean and meets the construction requirements. At the same time, it is necessary to do a good job in drainage work to prevent the construction quality and progress from being affected by rain and other reasons during the construction process.
Second, the installation and fixation of the template.
1.Installation of the template: Before installing the template, the template should be inspected to ensure that its size and shape meet the design requirements. When installing, it is necessary to follow the design plan to ensure that the position and angle of the template are accurate.
2.Fix the template: After the template is installed, fix it. When fixing, it is necessary to choose appropriate connectors and support materials to ensure the stability and safety of the formwork. At the same time, it is necessary to regularly check the fixing of the formwork to prevent the formwork from deforming or collapsing due to loosening and other reasons.
3. Concrete pouring and curing.
1.Concrete pouring: After the formwork is installed and fixed, concrete pouring can be carried out. Before pouring, the concrete should be inspected to ensure that its quality meets the requirements of the specification. When pouring, it is necessary to control the pouring speed and pouring amount to ensure that the concrete can fully fill the inside of the formwork.
2.Concrete curing: After the concrete is poured, it should be cured in time. During the curing period, the concrete should be kept wet to prevent cracking of the concrete due to drying. At the same time, it is necessary to avoid exerting excessive external force on the concrete during the curing period, so as not to affect its strength.
Fourth, construction safety precautions.
1.Safety management at the construction site: Obvious safety warning signs should be set up at the construction site to remind the construction personnel to pay attention to safety. At the same time, the construction site should be inspected regularly to eliminate potential safety hazards in a timely manner.
2.Safety protection of construction personnel: Construction personnel should wear safety protection equipment, such as safety helmets, safety belts, etc. When working at height, safety nets and other protective measures should be set up to ensure the safety of construction personnel.
3.Maintenance and management of construction equipment: Construction equipment should be regularly maintained and maintained to ensure that its performance is good. At the same time, it is necessary to strengthen the inspection and management of equipment to prevent the occurrence of safety accidents caused by equipment failure.
5. Construction quality control.
1.Construction quality inspection: In the construction process, the construction quality should be regularly inspected. The inspection content includes the size, shape, and fixation of the template. Problems should be dealt with in a timely manner to ensure that the construction quality meets the requirements.
2.Supervision of the construction process: There should be a special person to supervise the construction process to ensure the standardization and correctness of the construction process. At the same time, it is necessary to strengthen the training and management of construction personnel and improve their construction skills and safety awareness.
Sixth, the work after the completion of construction.
1.Removal of formwork and **: After the construction is completed, the formwork should be dismantled in time. The demolition should be carried out in accordance with the prescribed order to prevent structural damage caused by improper demolition. After dismantling, the formwork should be cleaned up and improved in time to reduce the waste of resources.
2.Cleaning of the construction site: After the construction is completed, the construction site should be cleaned up in time. The contents of the cleanup include waste, residual materials, etc. After the clean-up, the site should be kept clean and orderly, so as to create good conditions for subsequent construction.
In short, the construction process of cast-in-situ arch steel formwork needs to strictly control the construction quality and ensure the construction safety. In the construction process, it is necessary to make full preparations to strengthen the installation and fixing of the formwork, concrete pouring and maintenance. At the same time, it is necessary to strengthen the safety management of the construction site and the detection and control of construction quality. Only in this way can we ensure the smooth progress of the construction process of the cast-in-place arch steel formwork and ensure the quality and safety of the project.
