Description

Technical Field

[0001] The invention relates to the technical field of sound-absorbing panels, in particular to a high-strength suspended composite sound-absorbing panel. Background Art

[0002] Sound-absorbing board is an ideal sound-absorbing decorative material. It has the advantages of sound absorption, environmental protection, flame retardancy, heat insulation, heat preservation, moisture resistance, mildew resistance, easy dust removal, easy cutting, parquetry, simple construction, good stability, good impact resistance, good independence, high cost performance, etc. There are a variety of colors to choose from, which can meet the sound-absorbing decoration needs of different styles and levels.

[0003] The advantage of suspended sound-absorbing panels is that they can be flexibly arranged according to the size, shape and acoustic requirements of the space. They can be evenly distributed on the entire ceiling or set in a specific area. The installation method is to install multiple rings of specified specifications on the back of the panel, and flexibly hook them with the keel frame installed on the ceiling or wall. Multiple panels are spliced ​​together to form a complete sealed body.

[0004] However, the existing suspended sound-absorbing panels have the following shortcomings:

[0005] Because the hanging parts used in sound-absorbing panels are all made of metal, metal parts will oxidize and corrode due to various external factors.

[0006] The installation method of separating the hangers from the keel can easily cause the panel positioning structure to loosen, resulting in dangerous accidents such as detachment under the action of gravity.

[0007] The installation method of adding a keel inside the panel body requires grooving, which will damage the material structure and easily cause wrinkles or breaks during the transportation and installation process, which not only increases the difficulty for installers, but also increases safety hazards in the later stage.

[0008] Therefore, we proposed a high-strength suspended composite sound-absorbing panel to solve the above-mentioned problems. Summary of the invention

[0009] The purpose of the present invention is to provide a high-strength suspended composite sound-absorbing panel. Through a secondary reinforcement mechanism connected to a cross-dragon frame, when the structure between the superimposed body and the integrally cast rock plate sleeve becomes loose, one or more sides will move downward, which will generate a downward pulling force on the connected steel wires. The instantaneous external force will force the plastic sealing cover to undergo structural rupture, releasing the colloid in the storage barrel. The colloid can be diffused to evenly cover the structure of the integrally cast rock plate sleeve and the superimposed body. After it dries up, the two are reinforced for the second time to solve the problems raised by the above-mentioned background technology.

[0010] To achieve the above object, the present invention provides the following technical solution: a high-strength suspended composite sound-absorbing panel, comprising a whole cast rock plate sleeve, wherein a rectangular frame is encapsulated inside the whole cast rock plate sleeve, and a cross dragon frame is welded inside the rectangular frame;

[0011] The bottom of the cross dragon frame is provided with a secondary reinforcement mechanism;

[0012] The secondary reinforcement mechanism includes a connecting base, and extension brackets are fixedly installed at the four corners of the connecting base, and a square load-bearing frame is welded between the outer walls of the four extension brackets, and a group of hollow sleeves are fixedly installed inside the square load-bearing frame, and an insulation sleeve is fixedly installed on the inner wall of each hollow sleeve, and a storage barrel is wrapped inside each insulation sleeve, and a plastic sealing cover is provided at the sealing portion of each storage barrel, and a locking joint is fixedly installed on the outer wall of each plastic sealing cover, and a steel wire is fixedly inserted inside each locking joint, and a locking joint is fixedly installed at the end of each steel wire, and a conical plug rod is fixedly installed at the bottom of each locking joint.

[0013] Preferably, a group of lower racks are fixedly installed at the bottom of the cross dragon frame, the number of the lower racks in a group is equal to the plastic sealing cover, a stretch sleeve is fixedly installed at the bottom of each lower rack, and each steel wire is movably placed inside a corresponding stretch sleeve.

[0014] Preferably, the bottom of the integral cast rock panel sleeve is encapsulated with a metal inner sleeve, and the bottom of the metal inner sleeve is provided with an open-hole sound-absorbing steel plate, an acoustic foam layer and an outer wood veneer panel from top to bottom, and each outer wall of the rectangular frame is provided with a group of positioning rods, and each group of positioning rods is inserted into the interior of the integral cast rock panel sleeve.

[0015] Preferably, a group of threaded sleeves are fixedly installed on the top of the cross dragon frame, and the group of threaded sleeves are exposed on the top of the whole cast rock plate sleeve. The inside of each threaded sleeve is rotatably connected with an alloy threaded rod, and the outer wall of each alloy threaded rod is welded with a metal hanging ring.

[0016] Preferably, the metal inner sleeve, the perforated sound-absorbing steel plate, the acoustic foam layer and the outer wood veneer panel are jointly provided with two drainage grooves inside, and the outer wood veneer panel is provided with two collecting channels inside, and the liquid inlet end of each collecting channel is respectively connected to the discharge end of a corresponding drainage groove.

[0017] Preferably, the perforated sound-absorbing steel plate, the acoustic foam layer and the outer wood veneer panel are each provided with an equal number of assembly holes, a group of stamping sleeves are fixedly installed on the bottom of the metal inner liner, and the number of a group of stamping sleeves is equal to a group of assembly holes, and a rivet rod is fixedly inserted between each of the three assembly holes and the inner surface wall of a stamping sleeve.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention sets a secondary reinforcement mechanism. The composite whole is composed of a whole cast rock plate sleeve, a perforated sound-absorbing steel plate, an acoustic foam layer and an outer wood veneer panel, which are stacked and assembled with each other, and divided into two parts. The whole cast rock plate sleeve is independent, and the stacked body of the perforated sound-absorbing steel plate, the acoustic foam layer and the outer wood veneer panel is another part. During use, after the structure between the stacked body and the whole cast rock plate sleeve becomes loose, one or more sides will move downward, which will generate a downward pulling force on the connected steel wires. The instantaneous external force will force the plastic sealing cover to break in structure, releasing the storage barrel. The colloid in the structure can be evenly covered on the whole cast rock plate sleeve and the superposition body after diffusion. After it dries, the two are reinforced for the second time. The mechanism adopts the principle of mechanical transmission and utilizes the instantaneous pulling force generated by the kinetic energy of the superposition body to complete the release of the built-in colloid. The superposition body is provided with a channel to release the excess colloid in time, so as to avoid the accumulation of colloid and accelerate the drying rate of the colloid in the structure. After the composite is reinforced, the falling time of the superposition body can be extended, which provides sufficient preparation time for the formulation of solutions and avoids the probability of dangerous accidents.

[0020] 2. In the present invention, during the pressing and forming process of the integrally cast rock plate sleeve, the rectangular frame and the cross dragon frame are placed in the integrally cast rock plate sleeve material in advance to make the three a whole. After forming, a group of threaded sleeves can be evenly distributed on the top of the integrally cast rock plate sleeve, and thus, compared with secondary processing, the structure of the composite body will not be damaged. During the later installation, an alloy threaded rod with a metal hanging ring can be screwed into the threaded sleeve. This method will not damage the strength of the composite body, and at the same time, it also reduces the difficulty of installation, and ordinary installers can operate it.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Please see attached Figure 1 -Attached Figure 5 As shown, the present invention provides a technical solution: a high-strength suspended composite sound-absorbing panel, comprising an integrally cast rock plate sleeve 1, a rectangular frame 2 is encapsulated inside the integrally cast rock plate sleeve 1, a cross-dragon skeleton 3 is welded inside the rectangular frame 2, and a secondary reinforcement mechanism 4 is provided at the bottom of the cross-dragon skeleton 3.

[0029] according to Figure 2 , Figure 3 and Figure 4 As shown, the secondary reinforcement mechanism 4 includes a connection base 401, and extension brackets 402 are fixedly installed at the four corners of the connection base 401. A square load-bearing frame 403 is welded between the outer walls of the four extension brackets 402. A group of hollow sleeves 404 are fixedly installed inside the square load-bearing frame 403. The inner surface wall of each hollow sleeve 404 is fixedly installed with a heat preservation sleeve 405. The interior of each heat preservation sleeve 405 is wrapped with a storage barrel 406. The sealing portion of each storage barrel 406 is provided with a plastic sealing cover 407. Each plastic sealing cover 407 is provided at the sealing portion of each storage barrel 406. The outer wall of the cover 407 is fixedly installed with a locking joint 408, and a steel wire 411 is fixedly inserted inside each locking joint 408. A locking joint 412 is fixedly installed at the end of each steel wire 411, and a conical plug rod 413 is fixedly installed at the bottom of each locking joint 412. By presetting the above components, the provided insulation sleeve 405 plays a role of constant temperature. Since the storage barrel 406 stores repair colloid, the influence of the external temperature on the built-in colloid is reduced, thereby avoiding the problem of the colloid drying up or deterioration.

[0030] according to Figure 4 As shown, a group of lower frames 409 are fixedly installed at the bottom of the cross dragon skeleton 3, and the number of a group of lower frames 409 is equal to the plastic sealing cover 407. A stretch sleeve 410 is fixedly installed at the bottom of each lower frame 409, and each steel wire 411 is movably placed inside a corresponding stretch sleeve 410. By presetting the above components, the steel wire 411 has strong toughness and can cope with the instantaneous tension caused by the falling of the plate body, and the stretch sleeve 410 can limit the problem of curling of the steel wire 411, so as to avoid the untimely addition of colloid after the plate body falls off the whole cast rock plate sleeve 1, resulting in the failure to achieve the preset result.

[0031] according to Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the whole cast rock slab sleeve 1 is encapsulated with a metal inner sleeve 5, and the bottom of the metal inner sleeve 5 is respectively provided with an open hole sound-absorbing steel plate 6, an acoustic foam layer 7 and an outer wood veneer panel 8 from top to bottom, and each outer wall of the rectangular frame 2 is provided with a group of positioning rods 9, and each group of positioning rods 9 is inserted into the inside of the whole cast rock slab sleeve 1. By presetting the above components, since the rectangular frame 2 is pre-placed in the whole cast rock slab sleeve 1 when pressing, the two are a whole, which can increase the contact area between the cross dragon skeleton 3 and the whole cast rock slab sleeve 1 and provide force balance, and each group of positioning rods 9 is connected to the rectangular frame 2 and is inserted into the inside of the whole cast rock slab sleeve 1, which can further improve the load-bearing range of the whole cast rock slab sleeve 1.

[0032] according to Figure 1 , Figure 2 and Figure 3 As shown, a group of threaded sleeves 10 are fixedly installed on the top of the cross dragon skeleton 3, and the group of threaded sleeves 10 are all exposed on the top of the whole cast rock plate sleeve 1, and the interior of each threaded sleeve 10 is rotatably connected with an alloy threaded rod 11, and the outer wall of each alloy threaded rod 11 is welded with a metal hanging ring 12. By presetting the above components, since the threaded sleeves 10 and the alloy threaded rods 11 are rotatably connected, the welding process of the traditional metal hanging ring 12 is eliminated, thereby reducing the difficulty of plate assembly.

[0033] according to Figure 2 and Figure 5As shown, two drainage grooves 13 are jointly provided inside the metal liner 5, the perforated sound-absorbing steel plate 6, the acoustic foam layer 7 and the outer wood veneer panel 8, and two collecting channels 14 are provided inside the outer wood veneer panel 8. The liquid inlet end of each collecting channel 14 is respectively connected with the discharge end of a corresponding drainage groove 13. By presetting the above components, when the colloid flows out of the storage barrel 406, it will diffuse toward the periphery of the perforated sound-absorbing steel plate 6 and act on the connection between the metal liner 5 and the perforated sound-absorbing steel plate 6, and the excess colloid will be guided by the drainage groove 13, flow into the collecting channel 14, and gather toward the middle of the outer wood veneer panel 8, and finally fall to the ground at the corresponding position under its own gravity. After inspection, relevant personnel can know the location of the damaged plate at the first time.

[0034] according to Figure 2 and Figure 5 As shown, the perforated sound-absorbing steel plate 6, the acoustic foam layer 7 and the outer wood veneer panel 8 are each provided with an equal number of assembly holes 16 inside, a group of stamping sleeves 15 is fixedly installed at the bottom of the metal inner sleeve 5, and the number of a group of stamping sleeves 15 is equal to a group of assembly holes 16, and a rivet rod 17 is fixedly inserted between the inner surface walls of each three assembly holes 16 and one stamping sleeve 15. By presetting the above components, the metal inner sleeve 5, the perforated sound-absorbing steel plate 6, the acoustic foam layer 7 and the outer wood veneer panel 8 are installed in a layer-by-layer stacking manner. After being aligned and stacked, the two ends of the assembly holes 16 are flattened by stamping, one end is inserted into the stamping sleeve 15, and the other end covers the surface of the outer wood veneer panel 8.

[0035] The effect achieved by the whole mechanism is as follows: in the composite production stage, during the pressing process of the whole cast rock plate sleeve 1, the rectangular frame 2 with the cross dragon skeleton 3 installed can be first placed in the material, and the bottom of the cross dragon skeleton 3 is exposed. Each threaded sleeve 10 is evenly arranged on the top of the whole cast rock plate sleeve 1, and at the same time, the metal liner sleeve 5 is embedded in the bottom of the whole cast rock plate sleeve 1, and its bottom is exposed. After the whole cast rock plate sleeve 1 is prepared, the open-hole sound-absorbing steel plate 6 and the acoustic foam layer are stacked on the bottom of the whole cast rock plate sleeve 1 in turn. 7 and the outer wood veneer panel 8, at this time, the top of the perforated sound-absorbing steel plate 6 is fully aligned with the bottom of the metal liner sleeve 5, and at the same time, ensure that the assembly hole 16 is aligned with the corresponding stamping sleeve 15, and insert the rivet rods 17 in turn, and use stamping to act on the bottom of each rivet rod 17, forcing the two ends of each rivet rod 17 to deform, one end is stuck into the stamping sleeve 15, and the other end is flattened to the surface of the outer wood veneer panel 8. At the same time, each conical plug rod 413 is fixedly inserted in the superimposed structural layer.

[0036] During the installation phase of the composite body, the composite sound-absorbing panels are all complete bodies after leaving the factory, and the operator only needs to rotate each alloy threaded rod 11 into the threaded sleeve 10 to complete the assembly of the metal ring 12, and then carry out the splicing process of each complete body in turn according to the hooks reserved on the frame of the ceiling.

[0037] During the use stage of the composite, when the perforated sound-absorbing steel plate 6, the acoustic foam layer 7 and the rivet rods 17 in the outer wood veneer panel 8 are corroded by external factors, they will lose the restriction of the stamping sleeve 15 one by one, causing one or more sides of the superimposed layer to sink to a certain height. At this time, the conical plug rod 413 fixed therein will also drop to a certain height synchronously, which can generate a downward pulling force on the connected steel wire 411. Since the length of the steel wire 411 is limited, the instantaneous pulling force will directly act on the locking joint 412, forcing the plastic sealing cover 407 to rupture. At this time, the colloid in the storage barrel 406 will continue to flow out and drip onto the top of the perforated sound-absorbing steel plate 6, toward After spreading around, a small amount of colloid will enter the structure connected to the metal inner liner 5 and the perforated sound-absorbing steel plate 6, while the overflowed colloid will flow into the drainage groove 13, and then be redirected by the collecting channel 14 to gather towards the middle of the outer wood veneer panel 8. Finally, the colloid falls to the ground at the corresponding position under the action of gravity. Since the excess colloid can be discharged in time, the thin layer of colloid covering the structure connected to the metal inner liner 5 and the perforated sound-absorbing steel plate 6 can dry up quickly and provide short-term support for the entire cast rock plate sleeve 1 and the superimposed layer structure. Relevant personnel can accurately obtain the position of the damaged composite according to the position of the colloid, and make corresponding solutions later.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
