As a common safety protection facility, Galvanised Steel Roller Shutter Doors are widely used in commercial, industrial, and residential buildings. Their construction technology is crucial to ensure the door's stability, aesthetics, and functionality. This article will detail the construction technology of Galvanised Steel Roller Shutter Doors, including preparation, installation process, quality control, and finished product protection.
Materials and Equipment Preparation
Galvanised Steel Roller Shutter Doors mainly consist of curtain boards, drums, rails, transmission devices, and control systems. Before construction, all materials should be on-site and meet design requirements and national standards. Also, prepare the necessary construction tools and equipment, such as electric welders, electric drills, levels, chalk lines, steel tape measures, and plumb lines, to ensure smooth construction.
Design and Drawing Review
Before construction, carefully review the construction drawings to understand critical information such as the installation position, dimensions, elevation, and opening direction of the doors. Communicate with the design unit to ensure the accuracy of all parameters in the drawings. For doors with special requirements such as fire resistance and explosion protection, prepare the corresponding protective materials and measures.
Site Investigation and Measurement
Investigate the installation site to confirm if the opening size, embedded parts position, and quantity meet design requirements. If deviations are found, communicate with the design unit for adjustments. Measure and record on-site environmental data, such as floor levelness and wall verticality, to provide references for subsequent construction.
Line Out Rules
According to the design drawings, mark out the vertical lines on both sides of the door opening and the centerline for drum installation. Use tools such as chalk lines and plumb lines to ensure accuracy. For uneven door edges, chisel to ensure a flat installation surface.
Install Drum
Weld the shim of the drum bracket to the embedded iron pieces, ensuring a firm connection. Install the left and right brackets according to the centerline marked on the wall and adjust to horizontal. Ensure the drum is level and equidistant from the rails when installing. Temporarily fix and check adjustments to ensure the drum rotates flexibly after installation.
Install Transmission Device and Electrical Control System
As per design drawings, install the transmission system components and electrical control system. During installation, pay attention to the fitting gaps and safety clearances between components to ensure smooth transmission. Electrically test the motor, drum rotation, and other transmission components' working status to ensure everything is normal.
Install Curtain Boards
Assemble the curtain boards and check for flatness, diagonal lines, and straightness of both sides. Once deemed satisfactory, install the curtain boards onto the drum. Note the correct direction to avoid misinstallation. Ensure the flatness and verticality of the curtain boards during installation to maintain a good outward appearance of the door.
Install Rails
Align and plumb the rails according to the position lines in the drawings, ensuring accurate groove dimensions and uniformity from top to bottom. Weld the rails solidly to the embedded iron pieces on the wall using connectors to ensure stability. After installation, check the verticality and horizontality of the rails to meet design requirements.
Commissioning and Acceptance
After installation, perform overall commissioning. First, check the fit, contact conditions, and uniformity of the activity gaps between the drum, curtain boards, rails, and transmission parts. Then repeatedly open and close the door manually or electrically, observing if its operation is smooth and without abnormal sounds. If there are any blockages or jerks, make timely adjustments. Upon completing the commissioning, proceed to acceptance and document the related records.
Material Quality Control
Ensure all incoming materials meet design requirements and national standards. Strictly inspect and re-check materials to ensure specifications and performance indicators are met. Substandard materials should be promptly removed from the site.
Process Control
Enhance process control, ensuring all construction procedures strictly follow the design drawings and construction plan. Focus on the inspection and acceptance of key procedures and concealed works to ensure conformance with standards. Additionally, maintain construction records and concealed work acceptance records for reference.
Finished Product Protection
During installation, protect the surrounding finishing layers and completed products. When repairing or decorating the surrounding area after installation, promptly clean off any splashed mortar on the Galvanised Steel Roller Shutter Door using wet cotton. Prevent damage from hard objects like scaffold pipes colliding with the door.
Finished Product Protection
After installing the Galvanised Steel Roller Shutter Door, take effective measures for finished product protection. Assign specific personnel to manage and regularly inspect the integrity of the door before handover. Set up protective covers or other measures for vulnerable parts to prevent damage.
Safety Measures
During construction, strictly follow safety operation regulations and production systems. Workers must wear personal protective equipment. Strengthen safety management and supervision, especially for high-altitude and electrical work.
