Description

Fireproof sound-insulation thermal-insulation door and window section bar Technical Field The utility model belongs to the technical field of door and window profiles, and particularly relates to a fireproof, sound-insulation and heat-insulation door and window profile. Background The broken bridge aluminum is also called a heat insulation broken bridge aluminum section, and has more excellent performance than the common aluminum alloy section. The term "bridge" in the name of "bridge-cut aluminum" refers to a "cold-hot bridge" in a materialized sense, while the "broken" word indicates an action, i.e. "breaking the cold-hot bridge". In particular, because the aluminum alloy is metal and has relatively high heat conductivity, when the indoor temperature and the outdoor temperature are quite different, the aluminum alloy can be used as a bridge for transferring heat, and when the material is made into doors and windows, the heat insulation performance of the door and the window is reduced. The broken bridge aluminum is formed by breaking aluminum alloy from the middle, and the broken aluminum alloy is connected into a whole by adopting a hard plastic or pa66 nylon heat insulation material in the prior art, and because the heat conduction of plastic and nylon materials is obviously slower than that of metal, the heat cannot easily pass through the whole material, but the traditional broken bridge aluminum has poor fireproof performance, poor sound insulation and heat preservation effects and easy aging. Therefore, to above-mentioned technical problem, design fire prevention sound insulation cold-proof door and window section bar, set up aerogel felt layer in the middle of the aluminium alloy ex-trusions, separate aluminium alloy ex-trusions through aerogel, reached fire prevention sound insulation cold-proof, prevent ageing technical problem that the fracture's purpose was need to be solved by the technical problem of technical staff in the field. Disclosure of utility model In order to solve the problems, the utility model provides the fireproof, soundproof and thermal insulation door and window section bar, wherein the aerogel felt layer is arranged in the middle of the aluminum alloy section bar, and the aluminum alloy section bar is separated by the aerogel, so that the purposes of fireproof, soundproof and thermal insulation and aging cracking prevention are achieved. In order to achieve the above object, the present utility model provides the following solutions: The utility model provides a fire prevention sound insulation cold-proof door and window section bar, includes indoor section bar, outdoor section bar, sets up aerogel felt layer between indoor section bar and the outdoor section bar, and be used for fixing indoor section bar, outdoor section bar with the mounting of aerogel felt layer. Preferably, the fixing piece comprises a screw penetrating through the outdoor section bar, the aerogel felt layer and the outdoor section bar in sequence, and the screw is in threaded connection with the indoor section bar and the outdoor section bar. Preferably, a heat insulation rubber sleeve is arranged between the outer wall of the screw and the outdoor section bar, and a heat insulation rubber pad which is clamped with the heat insulation rubber sleeve is arranged between the outdoor section bar and the aerogel felt layer. Preferably, the diameter of the heat insulation rubber cushion is equal to the distance between two adjacent supporting ribs of the outdoor section bar. Preferably, an aluminum buckling strip is arranged outside the notch of the outdoor section bar far away from the aerogel felt layer, a hook-shaped structure is arranged on the aluminum buckling strip, and a convex column matched with the hook-shaped structure is arranged on the outdoor section bar. Preferably, the outdoor section is provided with a through hole for the heat insulation rubber sleeve to penetrate through, and the through hole is in interference fit with the heat insulation rubber sleeve.
