Description

Single-keel fireproof sound-absorbing aluminum alloy ceiling system

Technical Field

The utility model relates to a single fossil fragments fire prevention inhales sound aluminum alloy furred ceiling suspended ceiling system belongs to the application of aluminium and aluminum alloy class new material.

Background

Aluminum alloy furred ceiling suspended ceiling system is as its use by extensive domestic and foreign as third generation for building interior decoration furred ceiling board product, and aluminum alloy furred ceiling suspended ceiling system has obvious advantage such as light for traditional gypsum board furred ceiling suspended ceiling, plasticity is strong, decorative effect is good, service life is long etc. so at present in large-scale public building field such as airport hall, high-speed railway station, subway station, hospital, meeting exhibition center its inside space decorate the time the aluminum alloy furred ceiling system of choosing for the vast majority of furred ceiling part. At present, the aluminum alloy suspended ceiling system is standardized mainly by the following modes: the system comprises a square plate system, a batten system, a net-drawing ceiling system and a special-shaped ceiling system, wherein the batten system and the net-drawing ceiling system are open ceiling systems, the square plate system and the special-shaped ceiling system are closed ceiling systems. The common way of the existing closed ceiling system is that a frame which is staggered horizontally and vertically is formed by a horizontal keel and a vertical keel which are hung by a suspender, and a ceiling board is arranged on the keel frame in a hooking or clamping way. With the continuous development and progress of the interior decoration industry of buildings, new requirements are gradually made on the functionality of a suspended ceiling system, and some adjustment is made on the previously specified functional indexes, for example, the sound absorption performance of the suspended ceiling system in a closed space is required to reach the level II and above standards in GB/T16731-1997 Classification of sound absorption performance of building sound absorption products. GB50222-2017 'fire code for building interior decoration' also stipulates that when a water heating (or steam) heating system is installed inside indoor ceiling, wall surface, ground and partition decoration materials, the combustion performance of the decoration materials and heat insulation materials adopted by the ceiling is class A. And no matter the formula is taken in colluding to present closed square board system or buckle formula all adopts two keel structures and do not do special design to inhaling sound and fire behavior and handle, only pastes one deck non-woven fabrics through the mode of spouting the glue at the back of furred ceiling board, does not play the effect that increases fire behavior basically and also do not have the effect of obvious promotion sound absorption coefficient. Therefore, aiming at the defects and shortcomings of the mode, the aluminum alloy ceiling structure is expected to achieve the level II sound absorption performance and the level A combustion performance at the same time, and the aluminum alloy ceiling structure is expected to simplify the installation and reduce the consumable material.

The small folding lugs on the decorative ceiling board are matched with the hole grooves on the long folding edges to splice the decorative ceiling boards one by one. And the filling core layer is arranged on the back surface of the decorative ceiling board and is pressed by using a backing aluminum plate to finally form a three-layer structure of the decorative ceiling board, the filling core layer and the backing aluminum plate. The top surface of the keel is connected with the suspender through a bolt, and the other end of the keel is locked on the long folding lug of the decorative ceiling board. The hanger bar is secured to the concrete structure of the wall top by expansion bolts. A certain gap exists between the decorative ceiling board and the back lining aluminum board, fireproof sound insulation materials can be filled, the fireproof sound insulation materials adopted by the filling core layer are CAS nano aluminum magnesium fireproof damping sound insulation felt, the sound absorption performance reaches II level and above standard in GB/T16731-1997 sound absorption performance grading of building sound absorption products, the combustion performance can reach A level, the fireproof and sound insulation effects can be effectively achieved, and the effective service life is about 20 years. The back lining aluminum plate is placed on the back of the decorative ceiling board, the long folding lugs of the keels and the decorative ceiling board limit the movement of the decorative ceiling board in the height direction, and the back lining aluminum plate does not need to be fixed. The whole back lining aluminum plate is embedded into the back of the decorative ceiling board by utilizing the structure optimization and is limited by the keel, so that the installation is simpler and more convenient. This structure is for its structure that adopts single fossil fragments of traditional formula of colluding or joint formula aluminum alloy furred ceiling suspended ceiling system makes consumptive material greatly reduced to the mode that adopts two blocks of boards joint each other has reduced the construction degree of difficulty, makes the project cycle change in the management and control more. Meanwhile, good fireproof and sound-absorbing effects can be achieved. Meanwhile, the outer surface of the decorative ceiling board is treated by adopting a fluorocarbon spraying process, so that the surface color is high in selectivity and the decorative effect is good.

The beneficial effects of the utility model are that a single fossil fragments fire prevention inhales sound aluminum alloy furred ceiling suspended ceiling system has abandoned the two fossil fragments modes that traditional furred ceiling all need violently erect fossil fragments through the structural style of decorating mutual joint between the furred ceiling board, has reduced the use of material. On the other hand, the whole suspended ceiling system adopts a mode of decorating the suspended ceiling plate, filling the core layer and backing the aluminum plate, so that the sound absorption performance of the suspended ceiling system reaches II level and above standard in GB/T16731-1997 Sound absorption performance grading of building sound absorption products, and the combustion performance can reach A level. In addition, the whole ceiling system is made of aluminum alloy from the aspect of material, the keel is made of 6063T6 aluminum alloy sections, the back lining aluminum plate and the decorative ceiling plate are made of 3003 series aluminum alloy plates, the ceiling system is light in weight, fluorocarbon paint spraying treatment is carried out on the outer surface of the ceiling decorative plate, and various appearance effects can be achieved.
