Description

Technical Field

[0001] This invention belongs to the field of building decoration technology, and more specifically, it relates to a method for installing a ceiling light guide plate. Background Technology

[0002] The light guide plate utilizes optical-grade acrylic / PC sheets, then uses a high-tech material with extremely high refractive index and no light absorption to print light guide points on the bottom surface of the optical-grade acrylic sheet using laser engraving, V-shaped cross-grid engraving, and UV screen printing technology. The optical-grade acrylic sheet absorbs light emitted from a lamp and causes it to linger on its surface. When the light hits each light guide point, the reflected light diffuses in various angles, breaking the reflection condition and escaping from the front of the light guide plate. Through various density and size light guide points, the light guide plate can emit light uniformly.

[0003] Light guide plates have a wide range of applications. For aesthetic purposes, light guide plates are often installed on the ceiling of building lobbies to enhance both visual appeal and comfort. However, traditional ceiling light guide plate installation methods have some shortcomings. The splicing of the light guide plate and the perforated aluminum plate is often rough, resulting in uneven light transmission or shadows at the joints. Furthermore, the flatness of the steel frame welding is not strictly controlled, which can easily cause deformation of the light guide plate, thus affecting its aesthetic appeal. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a method for installing ceiling light guide plates.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for installing a ceiling light guide plate, comprising the following steps: S1. Measurement and layout: Based on the design and construction drawings and the overall design renderings, verify the actual dimensions on site and determine the actual dimensions of the finished surfaces of the lobby walls, columns and corridors. The above dimensions must be strictly controlled to ensure that the actual finished dimensions have an error of less than 2mm. S2. Layout and layout: Based on the actual dimensions on site and the actual dimensions of the light guide plate and guide rail from the light guide plate manufacturer, as well as the thickness of the acrylic, the actual dimensions of the perforated aluminum plate are laid out on site, and the aluminum plate is divided into equal parts. S3. Ceiling surface control: After the aluminum panels are cut, the horizontal and vertical control lines of the steel frame keel and the horizontal control line are marked on the wall according to the width of the aluminum panels. S4. Steel frame welding: Weld the steel frame of the wall according to the construction drawings and the actual dimensions on site. The flatness of the finished steel frame surface shall be controlled within 2mm. The infrared level and engineering line shall be used for verification and measurement. S5. Aluminum Plate Processing: Aluminum plate processing requires careful control of professional templates and equipment, and production and processing must be strictly carried out according to the layout drawing dimensions. The dimensions of aluminum plate production must be strictly controlled with an error within 1mm. S6. Light Guide Plate Processing: The light guide plate layout must be strictly based on the construction drawings and renderings. The curvature of each irregular edge must be marked on the CAD drawing. On-site, the light guide plate is laid out and spliced ​​according to the actual dimensions at a 1:1 scale. After splicing, once the actual dimensions are confirmed to correspond with the drawing dimensions, the curvature of the processing machine is adjusted for production. After processing, the light guide plate is actually spliced ​​on-site, and the actual dimensions are then verified on-site to ensure they match the drawing. S7. Light guiding performance test: Using light sources of different performance under the light and in a room with good light transmission (warm, neutral and strong light sources), the acrylic light guide sheet is projected to observe the different light projection effects to determine whether the overall light guiding effect of the light guide sheet meets the design requirements. S8. Installation Control: First, treat the base layer and then drill holes to install the hangers. Then, install the main and secondary keels on the hangers, then install the flame-retardant plate, then install the perforated aluminum plate, and finally install and fix the light guide plate.

[0006] Preferably, in step S1, an infrared level is used for cross-checking, with an error within 1 mm, and a control line is popped out using an ink line.

[0007] Preferably, in step S2, the aluminum plate production size is determined to be 515*2400mm, with adjustments made to the local corner positions based on the actual dimensions on site.

[0008] Preferably, in step S3, an infrared level is used for cross-control, and the errors of the horizontal, vertical and horizontal control lines are within 2mm.

[0009] Preferably, the aluminum plate is installed and fixed with self-tapping screws. When fixing the self-tapping screws, the force needs to be adjusted to prevent the aluminum plate from deforming. An infrared level and engineering lines are used to mark out cross grid lines to strictly control its flatness. During installation, a special person checks its dimensional flatness.

[0010] Preferably, the special fixed guide groove is fixed to the steel frame keel with self-tapping screws and connected to the light guide plate. An infrared level and engineering line are used to lay out cross grid lines to control the levelness of the guide rail.

[0011] Preferably, the seams of the light guide plate must not be glued to avoid light transmission shadows, and a special guide groove is used for fixation, and the vertical seams must be tight.

[0012] Preferably, the installation is completed and needs to be checked and accepted. The flatness / verticality is checked using an infrared level, with an error of ≤2mm. The light transmission effect should be free of black shadows, uneven light spots, etc.

[0013] Preferably, in step S7, the light source uses a cross-projection of blue, yellow, and green alternating light sources.
