[China Aluminum Industry Network] Metal ceilings are from Europe and the United States and other countries. Ten years ago, aluminum ceilings were regarded as high-end products and were rarely used in China. Now, with the improvement of technology and technological transformation, aluminum plates have started to fluctuate in price. Rationalization, aluminum ceilings are widely used in airports, railway stations, office buildings, shopping malls, subway stations and residential and other places.
Aluminum ceiling light weight, easy installation, aluminum plate has been processed in the factory, and can be processed into any shape, modeling flexibility. As a finished product, the decoration can be achieved after installation, and no other decoration is required on the surface.
The main construction method is to put the line → install the suspender → install the keel → install the aluminum plate → detailed adjustment and handling The release line measurement The pay line is a relatively precise process in the ceiling project and plays an important role in controlling the flatness of the ceiling. The measurement and payoff obeys the overall first and partial local measurement and control procedures, mainly the bullet elevation line and the keel position line. According to the horizontal line of the elevation of the floor and the design elevation, the horizontal line of the ceiling elevation will be projected onto the cylinder surface and the wall surface. The keel sub-position line shall be popped up on the top plate strictly according to the drawings and the axis, and the position line of the lifting point shall be used according to the layout of the aluminum plate. In order to ensure the smooth construction of the aluminum ceiling, use the reticle and level gauges to check the elevation line and keel position line and wait until they are accurate.
Elevation line and keel control line are introduced from wall and column line 50 and axis, design the elevation of aluminum suspended ceiling and the general form of the plane, in particular, the elevation of floating height of the model is on the top of the wall cylinder or the ceiling is fixed. The way to mark, to ensure a certain density, can react to the floating shape of the ceiling. This work is to create conditions for the next step on the one hand, and on the other hand, it is a review of the current situation of smallpox, such as wind pipes, water pipes, electric pipes, and structural beams and columns.
After the installation of the boom in the horizontal line of the ceiling elevation and the keel position line, the elevation of the lower end of the boom is determined. According to the position of the already hoisted suspension point, the impact drill is used to drill and install the expansion bolt, and the boom length is determined according to the elevation of the ceiling. Fixed boom. The spacing should be 900-1200mm. The spread point should be evenly distributed and the installation must be firm.
The keel keel is installed as a load-bearing rod, but at the same time it is a fixture for the fixed slats. It can be used in conjunction with the plate to meet the requirements of multi-functionality. It has light material, high strength, high temperature resistance, corrosion resistance, fire resistance, moisture resistance, chemical stability. Good and easy to assemble.
To install the keel, strictly follow the elevation line and layout drawing, and install the keel separately according to the location shown in the decoration manual. The keel will be assembled and the keel of the suspension fitting will be installed at the split line position.
Leveling the keel is a troublesome process in the entire aluminum ceiling construction. The leveling of the keel is also the key to the quality control of the suspended ceiling. Therefore, only the leveling of the keel can achieve the desired decorative effect of the veneer, otherwise the wavy suspended ceiling surface may not meet the requirements of the macro. For this important process, effective measures should be taken to control the smoothness of the keel, pull the vertical and horizontal elevation lines, start from one end, install one side, adjust one side, and fine tune it later, especially at the junction of the two water sections. We must work hard to make the elevations consistent, and there should be no mistakes or mistakes.
Installation of aluminum plate mounting aluminum plate is carried out on the basis of the leveling of the keel, in accordance with the aluminum plate control line from the middle to the direction of one by one to install in order, using the fastener with the ceiling to be fixed to the keel skeleton. The contact surface between the aluminum panel and the steel keel is insulated with an insulating sheet to prevent electrochemical corrosion. After the large-area aluminum plate is installed, due to the weight change, the deflection of the keel will be changed again, resulting in errors in the local flatness of the panel. After the deformation is stabilized, the aluminum plate is leveled to digest the effect of keel deformation on the flatness of the panel.
Detailed adjustment and handling of lighting, vents, and inspection openings are very important for the coordination of ceilings, especially large-area hall ceilings. The installation of equipment is complicated. From the perspective of construction, lighting, vents, inspection openings, and other installation locations are significant, and the decorative effect is significant. Very eye-catching. If other parts are doing well and these parts are crooked, the ceiling is hardly satisfactory. Smoke, automatic spray, vents and other equipment, and the ceiling surface convergence must be appropriate, the installation should be consistent. This requires the review of drawings between various professions, the discovery of errors, and timely correction.
Quality requirements 1, light steel keel and aluminum plate material, variety, style, specifications, etc. must meet the design requirements. Light steel keel installation position is correct, and the connection is firm and there is no looseness. The aluminum sheet surface layer should have no defects such as delamination, warping, cracking, paint loss, etc. The installation must be firm.
2. The hangers and keels of the light steel keel must be installed correctly and flatly without any bending deformation. The hanging parts should meet the requirements of the product portfolio. The surface of the aluminum plate should be clean, uniform in color, free from pollution and without defects. The bead is straight, wide and narrow. The form of the aluminum plate joints should meet the design requirements. The joints should be uniform in width and width, straight and tidy, and the joints should be straight and straight. The position of aluminum lamps such as lamps, smoke detectors, shower heads, air outlets, etc. is reasonable and beautiful, and the interface with the veneer is consistent and tight.
Precautions for the construction of aluminum ceilings 1 After scaffolding is erected, inspections shall be carried out. Only after complying with the requirements can the operator be operated. When operating at a high altitude, objects should be prevented from falling and hurting people. When working in the ceiling, horse paths should be erected. Non-supervised ceilings are strictly prohibited. , On-site operation using a ladder to pay attention to non-slip.
2 The on-site equipment and lighting electricity should be operated in strict accordance with the regulations; the site should pay attention to fire prevention and anti-virus; the safety staff should combine the specific conditions of the project to make safety disclosures to the operators and conduct regular safety education.
3 All kinds of exposed iron pieces must be treated for rust prevention; when installing lamps and ventilation hoods, they must not be damaged or contaminated; all air-conditioning, fire-fighting, electricity, and telecommunication equipment in ceilings must be erected on their own, not with suspended ceilings. Share hangers; more complex parts of pipeline valves and pipelines, pay attention to the reserved manholes; the fire pipes in the ceiling should be tested before the panel is sealed.
4 All welded parts must be full of welds, and the hanging buckles and pendants must be securely installed; after the ceiling decoration is installed, it must not be cut arbitrarily; if it is necessary to install equipment, drill holes with electric drills are strictly forbidden to open large holes.
After the installation of the ceiling, follow-up engineering operations should take protective measures to prevent pollution.
6 The ceiling seals should be arranged on the upper floor and after the roof waterproofing works are completed.
Due to the large number of aluminum buckle plate types, smooth lines, rich colors, good appearance, and more fire-proof, moisture-proof, easy-to-install, easy-to-clean, etc., it is welcomed by consumers and has been recognized by the world. With the development of the construction industry and the continuous improvement of construction technology, with the improvement of the quality requirements of the decoration, from the perspective of a large number of used engineering results, aluminum ceilings do have their own unique styles, from art, sound absorption, and fire protection. Comprehensive consideration of maintenance and service life, etc., aluminum ceiling can meet the above requirements, is an ideal form of ceiling, so the aluminum ceiling construction has a very broad prospects for development.
