Detailed explanation of construction technology of aluminum alloy keel ceiling
Construction technology of aluminum alloy keel ceiling;
1, elastic line positioning
According to the design drawings, combined with the specific situation, the keel and lifting point are located at the bottom of the floor. If the ceiling design needs a certain shape or pattern, the symmetry axis of the ceiling should be popped up first, and the keel and lifting points should be symmetrically arranged. The distance between keel and suspender and the distance between main keel are important factors affecting the height of suspended ceiling. Different keel sections and lifting point spacing may affect the distance between main keels. The spacing between various ceilings, keels and suspenders is usually controlled between1.0 ~1.2m.. Bullets should be clear and accurate. Aluminum alloy panel ceiling, if the slats are stuck on the keel, the keel should be perpendicular to the floor; If it is fixed with screws, it should be specially controlled according to the shape and design requirements of the slats.
2. Determine the ceiling elevation
Draw the design elevation line to the surrounding walls or cylinders; If the ceiling has different heights, the position of the variable section should rebound to the floor. Then angle aluminum or other sealing materials are fixed on the wall or cylinder, and the bottom surface of the sealing material coincides with the elevation line. The general specification of corner aluminum is 25mm x 25mm, and the corner aluminum of aluminum alloy panel ceiling should be the same color as the plate. Angle aluminum is mainly fixed with high-strength cement nails, and can also be fixed with nails.
3。 Cantilever or galvanized iron wire
Fixed at one end of the structure. The common method is to fix the suspender or galvanized iron wire with nail gun (also known as stone gun). There are two kinds of nails with holes and without holes to choose from. If suspenders are used as suspenders, the keel is mainly made of ordinary steel. The impact drill is used to fix the expansion bolt, and then weld the boom to the bolt. Fix the boom and keel. It can be fixed by welding or drilling holes with bolts.
4。 Installation and leveling of keel
When installation, according to determine the main keel (big keel) position and determine the elevation line, in the first place. Auxiliary keels (small and medium keels) should be placed near the main keels. After the keel is in place, completely control the elevation line (cross center line), start from one end, install, adjust, and then fine-tune until the keel is leveled and straightened. If the area is large, the horizontal line should also consider appropriate arching. When leveling, please pay attention to adjust from one end to the other to make it straight. Especially for aluminum alloy ceiling, the leveling and straightening of keel is a troublesome construction process. Whether the keel is flat or not is also the key to the quality control of wooden ceiling. Because only the keel is leveled, the lath facing can achieve the required decorative effect. Otherwise, the corrugated ceiling surface looks uncomfortable as a whole. Keels should be nailed down along the elevation lines of walls or columns. High-strength cement nails are commonly used when fixing, and the nail spacing should not be greater than 50cm. If the strength of the substrate is low and the fastening force is not good, corresponding measures should be taken to change the length of the expansion bolt or increase the length of the nail. Side keels are usually not load-bearing and are only used for sealing. Usually, connectors are used for length. The connector can be aluminum alloy or galvanized steel plate, and the surface of the connector can be barbed and connected with the square hole of the main keel. Completely correct the position and level of the main keel and the auxiliary keel, and install the connectors in the wrong position.
5。 Ceiling installation
When installing the ceiling, the geometric size of the plate should be suitable for the bearing wall of the aluminum alloy keel ceiling. If the grid size is 600mm x 900mm and 600mm x 1200mm, gypsum board cannot be installed, only mineral wool board can be installed.
Detailed explanation of construction technology of aluminum alloy keel ceiling
Aluminum alloy keel is an improvement of iron keel. Because aluminum will not rust after oxidation treatment? Color, the original iron paint keel will rust, yellow and lose paint because of oxidation, so aluminum alloy keel is a common building material for ceiling decoration. After reading Bian Xiao's introduction to you, I believe you have understood the construction technology of aluminum alloy keel ceiling.
