Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application shall fall within the scope of protection of the present application.
FIG. 1 is a schematic cross-sectional view of a self-supporting composite sound-absorbing panel according to one embodiment of the present invention; fig. 2 is a schematic cross-sectional view of a self-supporting composite sound-insulating panel according to another embodiment of the present invention. Referring to fig. 1 to 2, the self-supporting composite sound insulation and absorption panel of the present embodiment may include an outer maintenance structure (10), a sound insulation structure (20), a load-bearing frame structure (30), a fitting structure (33), a sound absorption unit (40), and an inner maintenance structure (50).
Referring to fig. 3 and 4, the load-bearing frame structure (30) of the embodiment may include a peripheral frame composed of profiles (31) and a support keel (32) fixed within the peripheral frame. The section bar (31) can be made of metal aluminum, aluminum alloy and other materials. The support keel (32) may be made of light steel or the like. The supporting keel (32) can be provided with a plurality of supporting keels, and the supporting forms can be diversified according to the needs, such as vertical supporting, horizontal supporting, inclined supporting and the like.
The outer maintenance structure (10) can be a steel plate, for example, a 1-2 mm steel plate can be used, the outer surface can be subjected to spraying treatment, and a 0.5-0.8 mm profiled color steel plate can be used. The outer service structure (10) is fixed on one side of the peripheral frame of the load-bearing frame structure (30), for example by welding or screwing.
The sound insulation structure (20) is arranged inside the external maintenance structure (10) and is fixed on the peripheral frame of the load-bearing frame structure (30) by the extrusion of the external maintenance structure (10). For example, the sound insulation structure (20) can be a damping reinforced cement fiberboard, a damping sound insulation composite board or the like. These boards are known in the art, for example, the damping sound insulation board is a high-performance constrained damping structural board, which is generally formed by compounding two boards with different densities, such as a magnesium rock board, a glass magnesium board, a gypsum board, a calcium silicate board, a high-density cement pressure board, and the like, through a layer of polymer damping material. The damping sound-proof board has the principle of larger sound energy conversion consumption on the damping layer, so that the transmission quantity is greatly reduced, the sound transmission coefficient is low, and the sound insulation quantity is greatly improved. Meanwhile, the composite structure with the high molecular damping material plays a role in decoupling and damping, so that the coincidence effect of the plate and the system is greatly weakened, and the sound insulation quantity is obviously improved.
After the outer maintenance structure (10) and the sound insulation structure (20) are fixed, a sound absorption unit (40) can be arranged in a cavity enclosed by the sound insulation structure (20) and the peripheral frame, and the sound absorption unit (40) wraps the support keel (32) therein as shown in fig. 1. For example, the sound absorption unit (40) may be made of a glass wool board, a glass cloth cover, sound absorption paper, a sound absorption plate, and the like. The sound absorption materials are filled in the cavity to play a sound absorption role and also have a heat preservation function.
After the sound absorption unit (40) is set, the inner maintenance structure (50) can be fixed on the other side of the peripheral frame of the load-bearing frame structure (30), thereby basically completing the self-supporting composite sound-insulating panel body structure. The outer maintenance structure (10) can be a metal plate, a plastic plate or the like, and specifically, a metal perforated plate, a sound absorption plate or the like can be used. The inboard service structure (50) may be welded. And is fixed to the outer peripheral frame by means of adhesion, screw connection, or the like.
As shown in fig. 1 and 2, the self-supporting composite sound-insulating panel may further include a fitting structure (33) provided on at least one side surface of the peripheral frame. The figures show that the embedding structures (33) are formed on two sides, and the embedding structures (33) can be formed on one side or more sides according to actual needs. Thus, when the self-bearing composite sound insulation and absorption plate is installed, the embedded structure (33) of one self-bearing composite sound insulation and absorption plate is embedded with the embedded structure (33) of the other self-bearing composite sound insulation and absorption plate, and therefore good fit and sealing among the self-bearing composite sound insulation and absorption plates are guaranteed.
Fig. 5 is a schematic view showing the installation of a plurality of self-supporting composite sound insulation panels (100) according to an embodiment of the present invention, and fig. 6 is a partially enlarged view showing the installation of a plurality of self-supporting composite sound insulation panels according to an embodiment of the present invention.
As shown in fig. 5 and 6, a plurality of self-supporting composite sound-insulating panels (100) can be assembled together and fixed to a building structure such as a concrete column (200) by means of connecting members (34) provided on the sides of the composite sound-insulating panels, thereby forming a closed structure of a building.
The specific embodiments are given above, but the present invention is not limited to the above-described embodiments. The basic idea of the present invention lies in the above basic scheme, and it is obvious to those skilled in the art that no creative effort is needed to design various modified models, formulas and parameters according to the teaching of the present invention. Variations, modifications, substitutions and alterations may be made to the embodiments without departing from the principles and spirit of the invention, and still fall within the scope of the invention.
