Technical Field

[0001] The utility model relates to the technical field of air duct fireproof boards, in particular to an inorganic floating bead silicon crystal air duct fireproof board. Background Art

[0002] Ventilation ducts (air ducts) are piping systems used for air transportation and distribution. In the technical regulations for ventilation duct construction, air ducts are divided into galvanized steel plate and ordinary steel plate air ducts, stainless steel air ducts, aluminum plate air ducts, phenolic composite air ducts and polyurethane composite air ducts, fiberglass composite air ducts, inorganic fiberglass air ducts and rigid polyvinyl chloride air ducts.

[0003] Duct fireproof board is a fireproof material specially used for ventilation ducts, which has excellent fireproof performance and durability. In the field of construction, duct fireproof board is widely used in various ventilation systems, such as air conditioning system, ventilation system, smoke exhaust system, etc., to ensure that the fire can be effectively prevented from spreading when a fire occurs.

[0004] For existing fireproof duct panels, during installation, they are usually fixed by using a nut and a screw rod. However, during use, the nut needs to be continuously screwed from one end of the screw rod to a specified position to play a fixing role. When installing multiple duct fireproof panels, it is very laborious and inefficient. Utility Model Content

[0009] Wherein, a quick adjustment and disassembly device is arranged on the air duct shell.

[0010] Preferably, the quick adjustment and disassembly device comprises two C-shaped frames, which are respectively sleeved on the upper and lower sides of the air duct housing, and both ends of the C-shaped frames are fixedly connected with horizontal plates.

[0011] Preferably, a screw rod is provided between the two corresponding transverse plates, both ends of the screw rod penetrate the outer surface of the transverse plate, and the outer surface of the screw rod is provided with two sets of quick-release nut mechanisms.

[0016] 1. The inorganic floating bead silicon crystal air duct fireproof board is installed at the required place by using bolts to pass through the installation and fixing holes on the mounting plate, and then the quick-release nut mechanism is opened and sleeved on the appropriate position on the screw, and then the two rotating clamps are merged together, and then the sleeves are sleeved on the outer surfaces of the two rotating clamp straight plates until the block is connected. At this time, the two rotating clamps are combined into one, and the threaded sleeves are arranged on the outer surface of the screw. At this time, the quick-release nut mechanism can be turned to adjust the position of the cross plate on the screw, and when it needs to be disassembled, the two rotating clamps can be separated by removing the locking sleeve, and the threaded grooves thereon will also be separated from the screw. Through the operation of the above structure, the air duct shell can be quickly and conveniently installed and disassembled, which improves the installation efficiency of the air duct shell to a certain extent, and avoids the need to twist the nut for a long time when using nuts to connect and fix in the traditional way, and the nut needs to be continuously twisted from one end of the screw to the specified position to play a fixing role, which brings about low installation efficiency.
