a. Drawing Preparation
The final construction drawing shall be formed after communication and modification by civil engineering, escalator manufacturer and Party A.
b. Installation of Escalator Main Body
The escalator manufacturer shall process, install, debug and trial the main body of the escalator according to the relevant drawings. After the installation is completed and qualified, the next installation can be carried out.
c. Construction Preparation
Confirm that the lighting pipeline and fire spray hidden at the bottom of the escalator are installed and tested to be qualified, and confirm that the construction environmental conditions on site meet the construction requirements. And prepare the construction materials, construction tools, scaffolding and construction personnel technical disclosure and other work.
d. Measurement and Positioning
According to the requirements of the design drawings and the geometric dimensions, the two sides and the bottom of the escalator are straightened, squared, ruled, measured and snapped to determine the size and quantity of the decorative metal plates.
e. Fixing Steel Keel Frame
Seal a layer of 12cm thick grade A bottom plate as the base, the steel keel frame of the horizontal and vertical bar and the main skeleton of the escalator for welding and fixing, and should be pre-anti-corrosion treatment. The position of the installation skeleton should be accurate and the combination should be firm. After installation, the center line and surface elevation should be thoroughly checked.
f. Installation of Metal Decoration Panel
After installing the LED light belt at the bottom and sealing the base, the escalator metal decorative panel will be installed. The installation sequence starts from the side panel, one side is installed, and then the other side is installed, and then the bottom corner arc plate is installed, and finally the aluminum plate at the bottom of the escalator is installed.
The method of fixing the metal decoration panel is mainly to set the installation hole or install the special angle code when the metal plate is processed, and then hang or pull riveted on the steel keel frame.
The closing of the luminator groove and the metal plate, the closing of the end, the pressing of the horizontal part, and the handover of two different materials are not only related to the decorative effect, but also have a greater impact on the use function. Generally in the drawing stage should be considered clearly, and draw comprehensive, do a good job of technical disclosure, according to the drawing construction can be.
h. Running Test and Self-test
After all the installations are completed, the escalator is again tested for operation, and the relevant dimensions of the overall completion are reviewed and self-checked to confirm whether they are in line with the design drawings and specification requirements.
a. Review the escalator civil construction dimensions should be carried out many times, including the measurement of lifting height, span, supporting beams and pits and so on. Especially pay attention to the upper and lower support beams of the escalator and the centerline of the escalator should be kept perpendicular.
b. Metal decorative panel varieties, quality, color, pattern, line must meet the design requirements, there should be product certification. The specification and shape of the keel must meet the design requirements, and the fixing of the board surface and the skeleton must be firm and not loose.
c. When installing metal decorative panels, the line should be lifted and checked in time so that errors can be eliminated in time. In order to ensure the quality of appearance, the position of bolts must be accurate.
d. When installing metal decorative panels, the size of the cut board should be accurate, the corners should be neat and smooth, the lap size and direction should be correct, and butt joints are strictly prohibited. Lap length should be in accordance with the design requirements, there shall be no seam phenomenon.
e. When the metal decorative panels are installed, pay attention to the parts that are easy to be contaminated with plastic film to cover the protection. Easy to be scratched, touch the parts, should be set up to protect the board or set up safety railing protection.
f. After the completion of construction, to review the building floor, ground finished surface and escalator platform location relationship, such as escalator area cover plate and ground material there is a height difference, or the relationship between the closure is unreasonable, all need to be adjusted in a timely manner.
g. Protective measures (e.g., paving, shading) must be taken before construction to protect other completed project works. During construction, no damage shall be caused to various utility lines and pre-buried parts due to operation.
i. The exterior decorative metal decorative panels in addition to meet the requirements of fire prevention, aesthetics, but also to ensure that any point on its vertical application of 250N force acting on the 25c ㎡ area, the exterior decorative panels do not produce breakage or lead to deformation of the seams.
