Description
Technical Field
The invention relates to the technical field of curtain walls, in particular to a combined adjustable sound insulation curtain wall.
Background
The curtain wall is the outer wall enclosure of the building, does not bear the weight, hangs like a curtain, so is also called as a curtain wall, and is a light wall with decorative effect commonly used by modern large-scale and high-rise buildings. The building outer protective structure or decorative structure consists of a panel and a support structure system, can have certain displacement capacity or certain deformation capacity relative to the main structure, and does not bear the function of the main structure.
Application publication number is CN 108487521A's chinese patent discloses a curtain gives sound insulation, including the curtain board, be equipped with honeycomb mechanism in the curtain board, honeycomb mechanism includes honeycomb panel one and honeycomb panel two, one side that honeycomb panel one and honeycomb panel two are close to all is equipped with the heat-resistant layer, and be equipped with the honeycomb inner core that a plurality of symmetries set up between honeycomb panel one and the honeycomb panel two, the both ends of curtain board are equallyd divide and are do not the symmetry and be equipped with the lug, a side hole groove of lug, one side in the hole inslot is equipped with reset spring one, one side of reset spring one is equipped with the stopper, the opposite side of stopper is equipped with connecting rod one, the one end of connecting rod one extends to. Has the beneficial effects that; support curtain board that can be better has improved the bearing capacity of curtain board, and the honeycomb inner core can the dispersion power effect and inhale the effect of sound, has reduced the noise of surrounding environment, has improved user's comfort level to reach the curtain board with the fixed effect of frame, reach the separation of curtain board and frame, make reasonable in design, easy operation.
However, the sound-insulating curtain wall has a disadvantage that the noise is large or small, and the sound-insulating curtain wall absorbs sound through the honeycomb inner core, so that only a part of noise can be absorbed well, the curtain wall may be used for building surfaces in various environments, and the noise in various noise environments is various, so that the sound-absorbing effect of the sound-insulating curtain wall is not good, and the applicability is not high.
Disclosure of Invention
The invention aims to provide a combined adjustable sound insulation curtain wall, which has the advantage that the sound insulation curtain wall can be adjusted according to the noise environment so as to have better sound absorption effect under the current use environment.
The above object of the present invention is achieved by the following technical solutions:
the utility model provides a curtain gives sound insulation with adjustable combination, includes the curtain board, the curtain board is formed by two end plates, two blocks of curb plates and two roof combinations, vacuole formation between end plate, curb plate and the roof, be provided with fixed abatvoix and removal abatvoix in the cavity, fixed abatvoix is fixed to be set up in one side on the curb plate, it slides and sets up to remove the abatvoix in the cavity, the flange department of removing between abatvoix and the fixed abatvoix encloses and is equipped with flexible membrane, it inhales the sound space to remove to form between abatvoix, fixed abatvoix and the flexible membrane, it is used for connecting telescopic structure between them to remove to be provided with between abatvoix and the fixed abatvoix and is used for connecting, be provided with the manual regulating part that is used for adjusting the.
When the technical scheme is implemented, when the curtain wall board is manufactured, firstly, the curtain wall board is used on a building in which area, and if the curtain wall board is used in a place with a poor noise environment, the volume of a sound absorption space is increased a little; at this moment, start manual regulating part with the hand, let the extending structure grow, the distance between removal abatvoix and the fixed abatvoix at this moment will grow, inhale the volume in sound space and just can grow. After the curtain wall board is installed on the surface of a building with a large noise environment, a large amount of noise enters the mobile sound-absorbing board through the curtain wall board and is absorbed into the sound-absorbing space by the mobile sound-absorbing board, and because the volume in the sound-absorbing space is large, the noise is continuously rebounded and rubbed between the mobile sound-absorbing board and the fixed sound-absorbing board, and finally the noise is reduced, so that the large amount of noise is absorbed by the curtain wall board on the building; if the curtain wall board is used in the place that the noise environment is comparatively good, can directly install without adjusting the distance between removal abatvoix and the fixed abatvoix. Set up like this and can adjust so that curtain board noise-absorbing effect preferred under current service environment according to the noise environment sound space of inhaling.
Furthermore, a sound inlet hole is formed in the side plate on the other side, a sound through pipe is connected between the sound inlet hole and the movable sound absorption plate, and the sound through pipe is a corrugated pipe.
