To ensure the quality of the installation of the partition track, it is necessary to strictly control from aspects such as early preparation, installation process control, precision calibration, fixing methods, detail handling, and completion acceptance. The following are specific key points and operational suggestions:

I. Early Preparation: Precise Measurement and Planning

1. Space Dimension Verification

   • Use laser rangefinders, spirit levels, and other tools to measure the length, width, and height of the installation area, as well as the verticality and flatness of the wall/ceiling. Key points to note:
     • The horizontal datum line of the track installation location (e.g., the ground track should be consistent with the ground elevation, and the ceiling track should match the elevation of the ceiling keel).
     • Whether the distance between the two side walls is consistent (error ≤3mm), to avoid "track misalignment" after the track is installed.
   • Example For example, if the installation height of the ceiling track is 3 meters, ensure that the elevation difference at both ends is ≤2mm; otherwise, the track will tilt, causing the pulley to jam.

2. Track Selection Matching

   • Select the track type according to the partition weight and frequency of use:
     • Lightweight track Suitable for single-partition weight <50kg, such as office screen partitions, track thickness ≥2mm.
     • Heavy-duty track Suitable for large partitions (such as banquet hall partitions), when the weight is >200kg, thickened steel (thickness ≥5mm) or aluminum alloy tracks should be used, and the track should have reinforcing ribs reserved.
   • Confirm that the track material matches the installation environment (e.g., stainless steel tracks for humid environments, flame-retardant materials for fire-protected areas).

II. Installation Process: Positioning, Fixing, and Precision Calibration

1. Track Positioning and Laying Out

   • Use a chalk line box or laser line projector to mark the center line and edge lines of the track on the wall/ceiling, ensuring that the lines are straight and without bends.
   • For multi-section spliced tracks (e.g., extra-long tracks need to be installed in sections), a 5-10mm expansion joint should be reserved at the joints to prevent deformation due to thermal expansion and contraction.

2. Track Fixing Methods

   • Ground Track Fixing ：
     • Concrete walls/floors: Use expansion bolts (diameter ≥8mm, spacing 300-500mm) for fixing. The drilling depth should be ≥50mm to ensure that the bolts are firmly anchored.
     • Tile/wooden floor: First, groove the track position (depth consistent with the track thickness), embed the track, and then use structural adhesive + expansion bolts for double fixing to avoid damaging the decorative surface.
   • Ceiling Track Fixing ：
     • When the ceiling is a light steel keel, the track should be welded to the main keel or connected with L-shaped angle brackets (thickness ≥4mm), with no less than 2 screws at each connection point.
     • For concrete ceilings, fix directly with expansion bolts. The bolts should avoid overhead pipelines (check the overhead pipeline diagram before installation).

3. Levelness and Straightness Calibration

   • Levelness Check ：
     • Use a laser level to scan the entire track. The bubble offset within each 1-meter range should be ≤1mm, and the total error should be ≤3mm.
     • If the track is tilted, add stainless steel shims (thickness 1-3mm) under the fixing point for adjustment until it is level.
   • Straightness Check ：
     • Pull a 5-10-meter thin steel wire, close to the inner edge of the track, and observe whether the gap between the steel wire and the track is uniform (error ≤2mm) to avoid track "bending" causing the partition to jam.

III. Detail Handling: Accessory Installation and Functional Testing

1. Pulley and Track Matching

   • Before installation, check whether the pulley bearings are flexible. The pulley diameter should match the track groove width (error ≤0.5mm).
   • Heavy partitions should use double pulley groups (2-4 pulleys per group), evenly distributed on the track to avoid excessive stress on a single point.

2. Limit Device Installation

   • Install rubber buffers or metal limit blocks at both ends of the track to prevent the partition from hitting the wall during sliding. The height of the limit block should be 20-30mm higher than the top of the pulley to ensure effective blocking.
   • For electric partition tracks, install electromagnetic induction limiters synchronously, which work with the control system to accurately control the stopping position of the partition.

3. Sealing and Dust Prevention

   • The gaps between the track and the wall/floor should be filled with Silicone sealant Fill, joint width 5-8mm, ensure sealing and waterproofing.
   • Installation in track groove Dust brush strip Or rubber seal strip, to prevent dust accumulation affecting pulley operation (especially suitable for environments with high wind and sand).

IV. Completion Acceptance: Functional Testing and Hidden Trouble Inspection

1. Load-bearing test

   • After installation, the track is Full-load test run : Install all partitions in place, push back and forth 5-10 times, observe if the track has deformation, looseness or abnormal sound.
   • Heavy-duty tracks require additional Static load test (Load 1.5 times the weight of the partition, maintain for 24 hours), check whether the track deflection is ≤5mm.

2. Precision re-check

   • Re-check the horizontality, straightness and installation dimensions of the track with a spirit level and steel tape measure to ensure that they meet the design requirements (e.g., track elevation error ≤3mm, length error ≤5mm).
   • Check if the track interfaces are smooth, the splicing seam ≤2mm, and there is no height difference.

3. Hidden trouble inspection

   • Tighten all fixing screws, tap the track with a wrench to check for loose welding or looseness.
   • Clean debris inside the track, apply Track-specific lubricating grease (such as lithium-based grease), ensure that the pulley runs smoothly without jamming.

V. Common Problems and Solutions

Summary

The installation quality of the movable partition track directly affects the service life and user experience of the partition, the key lies in Accurate measurement, firm fixing, strict calibration and detail processing . It is recommended that professional teams carry out the construction, and make a record of the hidden engineering during the installation process (such as the position of the fixing points, the thickness of the shims, etc.), which is convenient for later maintenance.
