Installation technical instructions

I. Installation of general instructions

1、Pre-installation of the purification area of the air duct, the site for cleaning, clear the site of all items not related to construction.

2, by the contractor according to the design drawings to make a specific secondary design, including the top plate layout, top plate decomposition diagram, wall plate layout, wall plate decomposition diagram and the relevant node diagram by both sides to confirm the specifications in accordance with the actual need to order.

3, color steel plate factory should take protective measures film, proper packaging, civilized loading and unloading, reduce the surface layer in the transportation process by damage. Color steel plate and all kinds of accessories storage site must be dry and clean, flat and solid, conditions should be in the field around the enclosure in order to manage. Color steel plate stacking should be neat and tidy, its stacking height shall not exceed 2.0 meters.

4, color steel plate transported to the scene, should be issued product certification and related documents, good inspection procedures. Sandwich panel surface should not be scratched, its geometry should be in line with the requirements of the design drawings, such as scratches, protective film removal after the contractor for technical processing.

5, the installation process does not tear off the wall plate surface plastic protective film, prohibit impact and tread on the board. Fittings and various materials should be strictly checked its specifications, performance and degree of integrity of unqualified or damaged fittings are strictly prohibited.

6、All installation gaps in the clean area should be sealed with silica gel, before gluing, the installation gaps must be strictly cleaned to remove impurities and oil, to ensure that the paste is dense, to prevent dislodging and accumulation of dust. Silicone surface should be smooth, can not appear wrinkled skin phenomenon.

7, every day after the end of construction need to clean up the site cleaning, to do every day after the material clean, site clean.

II. Color steel sandwich panel installation

The installation of the color steel sandwich panel should be carried out after the basic completion of the building decoration project and the completion of the main part of the ventilation, power and electricity, process supervisor. In the installation process cutting machine and other machinery and installation accessories and construction site should be cleaned at any time, wipe clean. According to the installation order for the first installation of the wall plate after the installation of the top plate.

1, wall plate installation

(1) according to the color steel sandwich panel partition plane layout map strict release line, people, logistics and other long distance should be consistent, the error should be less than 1.5 ‰. The corner of the wall should be vertically intersected, and the error of the diagonal line of the room discharging should be less than 1‰.

(2) in accordance with the benchmark, clean the ground, ensure that no dust on both sides of the manger, every interval of 0.5m with a nail to the aluminum alloy manger fixed to the ground, the manger and the ground should be attached to a close fit.

(3)The verticality of the wall plate installation is corrected by magnetic line plumbing, and its deviation should not be greater than 1‰. In order to prevent cumulative error caused by the wall plate tilt distortion, the gap between the wall plate should be strictly controlled within 2.5mm, and should be kept uniform up and down.

(4) wall plate and the top plate connected to the formation of the corner of the installation of shaded arc aluminum, should be cleaned first, wall plate and the top of the formation of the corner with the building sealant seal. Yin corner plastic base and wall top plate connection with aluminum rivets fixed, aluminum profile should be installed with color steel plate paste close fit, can not appear wavy gap.

(5) switch socket line pipe pre-buried by the color steel plate installation workers with electricians, the electrician to confirm the size and location of the switch socket opening, by color steel plate installation workers are responsible for opening.

2、Top plate installation

(1) in the installation, should first according to the second design layout plan to determine the need to hang beams and strengthen the hanging point of the hanging, anchors and other three-dimensional components and roof beams of the linkage fixed position specific as follows hanging spacing every 1.2m arrangement, should be done to the vertical level. The roof beam is fixed with φ10mm expansion screws, and the other end of the hanging bar is connected with galvanized flange bolts and special galvanized dark hanging beams in order to adjust the flatness of the roof plate.

(2)The top plate is installed according to the direction of the room, and the gap should be kept within 2-3mm, and the top surface is connected with the dark suspension beam with rivets every 0.5m, so as to make the connection between each other firmly.

(3)When the length of the top plate is greater than 3m, except in the width direction of hanging dark hanging beam, the length direction should be done to strengthen the processing, with special C-beam reinforced hanging beam and the top plate keel with dovetail screws, and then use the wire hanging up tight.

(4)After the construction of the ceiling board, other types of work in the construction of the ceiling board to make good protection measures, is strictly prohibited in the ceiling board on a large scale processing production.
