Description

Technical Field

[0001] The present invention relates to a dry hanging technology for installing building panels on a wall, and in particular to a building panel dry hanging system. Background Art

[0002] In recent years, rapid economic development has led to a concentration of populations in cities, resulting in the proliferation of tall buildings and residential buildings. This, in turn, has led to a gradual reduction in green space. This, coupled with industrial development and the widespread use of vehicles, has resulted in the urban heat island effect. Modern buildings and residences are primarily constructed of reinforced concrete. During the day, the concrete exterior walls and roofs of these buildings and residences trap solar radiant heat, which is then released at night. This heat causes urban temperatures to be higher than those of surrounding areas, both during the day and at night, undoubtedly exacerbating the urban heat island effect. Summary of the Invention

[0023] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the relative position terms used in the following description, such as "front-back direction X", "left-right direction Y", and "top-bottom direction Z" are relative to each other. Figure 1 The orientation shown is a reference, and the front-to-back direction X, the left-to-right direction Y, and the top-to-bottom direction Z are perpendicular to each other, and similar components are represented by the same reference numerals.

[0024] See Figure 1 and Figure 2 An embodiment of the dry-hanging system for building panels of the present invention is suitable for installation on a wall 1 of a building (not shown), and comprises a plurality of vertical members 2, a plurality of horizontal members 3, and a plurality of dry-hanging modules 4.

[0025] The vertical members 2 are installed on the wall 1 at intervals along a left-right direction Y and extend along a top-bottom direction Z respectively.

[0026] See Figures 2 to 4 The horizontal members 3 are installed at intervals along the top-bottom direction Z on the side of the vertical member 2 opposite the wall 1 and extend along the left-right direction Y. Each horizontal member 3 is made of aluminum alloy and includes a rear base plate 31 capable of resting against the side of the vertical member 2 opposite the wall 1, a top protrusion 32 extending forward from the top of the rear base plate 31 along the front-back direction X and spaced apart from the vertical member 2, a bottom plate 33 extending forward from the bottom end of the rear base plate 31, and a front baffle 34 extending upward from the end of the bottom plate 33 opposite the rear base plate 31. The rear base plate 31, the top protrusion 32, the bottom plate 33, and the front baffle 34 cooperate to define a forwardly open accommodating space 35. The rear base plate 31 and the top protrusion 32 cooperate to define a rearwardly open positioning slot 36.

[0027] Each dry hanging module 4 includes a building board 41 , four hanging members 42 , four main elastic members 43 , a plurality of locking members 44 , and four auxiliary elastic members 45 .

[0028] The hangers 42 of each dry-hanging module 4 are fixedly connected to the building board 41 in pairs along the top-bottom direction Z, and the hangers 42 are hung in pairs on two adjacent ones of the horizontal members 3 along the top-bottom direction Z. Each hanger 42 is made of aluminum alloy and comprises a front base plate 421 connected to the building board 41 and resting against the front end of the top protrusion 32 and the front end of the front baffle 34; a top plate 422 extending rearward from the top end of the front base plate 421 and resting against the top end of the top protrusion 32; an insertion plate 423 connected to an end of the top plate 422 opposite the front base plate 421 and extending bottomward and engaging with the positioning groove 36; a partition plate 424 extending rearward from the front base plate 421 into the accommodating space 35; and a bottom protrusion 425 extending bottomward from the partition plate 424 and spaced apart from the front base plate 421 along the front-to-back direction X. The partition 424 cooperates with the bottom protrusion 425 and the front substrate 421 to define a bottom-open slot 426 for the front baffle 34 to fit into. The front substrate 421 has two through holes 427 extending along the front-to-back direction X and spaced apart along the left-to-right direction Y.

[0029] See Figures 3 to 5 The main elastic members 43 of each dry-hanging module 4 correspond to the hangers 42 and are located in pairs within two corresponding accommodating spaces 35 of the horizontal member 3 that are adjacent along the top-bottom direction Z. Each main elastic member 43 includes a rear support portion 431 that abuts against the rear base plate 31 of the corresponding horizontal member 3, a top support portion 432 connected to the top of the rear support portion 431 and configured to elastically abut the top protrusion 32, a front support portion 433 connected to the top support portion 432 and configured to elastically abut the front base plate 421, a first clamping portion 434 connected to the front support portion 433 and configured to elastically abut the partition 424, a bottom support portion 435 connected to the bottom of the rear support portion 431 and configured to elastically abut the bottom plate 33, and a second clamping portion 436 connected to the bottom support portion 435 and configured to elastically abut the bottom protrusion 425.

[0030] It should be noted that each hanger 42 also has a rubber gasket 428 attached to the insertion plate 423, the top plate 422 and part of the front substrate 421 facing the insertion plate 423, and another rubber gasket 429 attached to the side of the bottom protrusion 425 adjacent to the card slot 426, the side of the partition 424 adjacent to the card slot 426 and the side of the front substrate 421 adjacent to the card slot 426, so that when the hanger 42 is hung on the horizontal member 3, the insertion plate 423 is embedded in the positioning groove 36, the top plate 422 is attached to the top of the top protrusion 32, the front substrate 421 is against the front side of the top protrusion 32, and the front baffle 34 is embedded in the card slot 426, the rubber gaskets 428 and 429 can provide an anti-slip function. In addition, each main elastic member 43 also has a rubber gasket 437 covering the outside of the rear support portion 431, the top support portion 432, the front support portion 433, the first clamping portion 434, the bottom support portion 435 and the second clamping portion 436, so that when the main elastic member 43 is elastically pressed between the top protrusion 32 and the bottom plate 33, between the rear substrate 31 and the front substrate 421, and between the partition 424 and the bottom protrusion 425, the rubber gasket 437 can provide an anti-slip function.

[0031] See Figure 4 and Figure 5 The through holes 427 of the front substrate 421 of each hanger 42 are located on opposite sides of the corresponding main elastic member 43 along the left-right direction Y, and the through holes 427 are used to allow two of the locking members 44 to extend through and be screwed to the building board 41. The two locking members 44 can be used to limit the position of the main elastic member 43 along the left-right direction Y.

[0032] It is worth noting that in other variations of this embodiment, the front substrate 421 may have only one through-hole 427 , and the main elastic member 43 may further have a through-hole (not shown) extending along the front-to-back direction X and communicating with the through-hole 427 . The through-hole 427 and the through-hole allow one of the locking members 44 to extend through and be screwed to the building board 41 .

[0033] See Figure 3 、 Figure 5 and Figure 6The auxiliary elastic member 45 of each dry-hanging module 4 is disposed between the hanger 42 and the corresponding horizontal member 3. Each auxiliary elastic member 45 comprises a fixed end 451 locked to the top protrusion 32 of the horizontal member 3, a movable end 452 locked to the top plate 422 of the hanger 42, a buffer portion 453 elastically connected between the fixed end 451 and the movable end 452 along the left-right direction Y, and a fine-tuning member 454 screwed between the movable end 452 and the top plate 422 and constantly in contact with the top protrusion 32. When the building board 41 is subjected to an external force along the left-right direction Y, the buffer portion 453 provides elastic cushioning along the left-right direction Y to absorb the external force. When the fine-tuning member 454 is rotated so that the fine-tuning member 454 is relatively locked into the top plate 422, the fine-tuning member 454 is constantly pressed against the top protrusion 32, and the top plate 422 moves in a direction away from the top protrusion 32, thereby driving the building board 41 to move toward the top; conversely, when the fine-tuning member 454 is rotated so that the fine-tuning member 454 is relatively locked away from the top plate 422, the top plate 422 moves in a direction close to the top protrusion 32, thereby driving the building board 41 to move toward the bottom.

[0034] See Figure 1 and Figure 5 The dry hanging modules 4 are hung in an array on the horizontal member 3, so that the building panels 41 are connected to form a building wall 411 spaced apart from the wall 1. The distance between the building wall 411 and the wall 1 is about 7.5 cm, and the building wall 411 and the wall 1 cooperate to define an air flow channel 412 connected to the outside for air circulation. The space between two adjacent building panels 41 is filled with silicone sealant and the edges are treated (such as Figure 5 As shown), to prevent the air in the air flow channel 412 from flowing out to the outside through the gap between the two adjacent building boards 41. It is worth noting that, refer to Figure 7 In other variations of this embodiment, in addition to filling with silicone for edge finishing, an edge trimming material 46 may be provided at each end of each building board 41 along the top-bottom direction Z and the left-right direction Y. Silicone may be filled between adjacent edge trimming materials 46 of two adjacent building boards 41 to enhance the connection strength between the building boards 41. The edge trimming materials 46 may be made of metal materials such as stainless steel and aluminum.

[0035] See Figure 8 The building board dry hanging system further includes an air intake module 5 arranged at the bottom end of the building wall 411 and an exhaust module 6 arranged at the top end of the building wall 411.

[0036] The air intake module 5 includes a bottom cover plate 51 connected to the bottom end of the building wall 411, a solar panel 52 disposed on the outside of the bottom cover plate 51, and multiple air intake fans 53 (only one is shown in the figure) disposed on the inside of the bottom cover plate 51 and powered by the solar panel 52. The bottom cover plate 51 cooperates with the building wall 411 and the wall 1 to define the air flow channel 412. The bottom cover plate 51 is separated from a base wall 101 disposed on the ground 100 to form an air intake hole 55 connecting the air flow channel 412 with the outside. The air intake module 5 also includes an insect screen 54 disposed on the air intake hole 55 to prevent foreign matter from entering the air flow channel 412. The air intake fan 53 is located within the air flow channel 412 and is used to blow external air into the air flow channel 412 through the air intake hole 55. It should be noted that, in other implementations, the solar panel 52 can also be installed on a roof of the building (not shown) and can also provide power to the intake fan 53, so it is not limited to this embodiment.

[0037] The exhaust module 6 includes a solar panel 61 connected to the top of the building wall 411, a top cover plate 62 connected to the top of the solar panel 61, a top cover plate 63 covering the top of the top cover plate 62, and multiple exhaust fans 64 (only one is shown in the figure) located inside the solar panel 61 and powered by the solar panel 61. The top cover plate 62, the top cover plate 63, the bottom cover plate 51, the building wall 411, and the wall 1 cooperate to define the airflow channel 412. The top cover plate 63 has an exhaust hole 631 connecting the airflow channel 412 with the outside, and an insect screen 632 located in the exhaust hole 631 to prevent foreign matter from entering the airflow channel 412. The exhaust fan 64 is located in the airflow channel 412 and is used to exhaust air in the airflow channel 412 to the outside through the exhaust hole 631. The bottom cover plate 51, the top cover plate 62, and the top cover plate 63 are all made of stainless steel. It should be noted that in other embodiments, the solar panel 61 can also be installed on the roof to power the exhaust fan 64, while the top cover plate 62 is connected to the top of the building wall 411, and the exhaust fan 64 is installed inside the top cover plate 62. Therefore, this embodiment is not limited thereto.

[0038] The intake fan 53 draws cool air into the air flow channel 412 , and the exhaust fan 64 exhausts hot air from the air flow channel 412 , so that air forms a convection circulation in the air flow channel 412 .

[0039] The building board dry hanging system further includes an aluminum foil bubble film layer (not shown) attached to the wall surface of the wall 1 adjacent to the air flow channel 412 for reflecting radiant heat.

[0040] When assembling the building panel dry-hanging system of the present invention, the aluminum foil bubble film layer must first be applied to the wall 1. The vertical members 2 are then installed at intervals along the left-right direction Y on the wall 1. The horizontal members 3 are then installed at intervals along the top-bottom direction Z on the vertical members 2. The dry-hanging modules 4 are then hung on the horizontal members 3. First, the main elastic member 43 of each dry-hanging module 4 is placed into the corresponding accommodation space 35 of the corresponding horizontal member 3. The building panel 41, secured with the hanger 42, is then hung on the horizontal member 3 via the hanger 42. The insertion plate 423 of each hanger 42 is inserted into the positioning slot 36. The partition 424 and the bottom protrusion 425 are inserted between the first clamping portion 434 and the second clamping portion 436. The front baffle 34 is then inserted into the retaining slot 426, so that the front base plate 421 abuts against the front end of the top protrusion 32, the front end of the front support 433, and the front end of the front baffle 34. The secondary elastic member 45 is then locked between each hanger 42 and the corresponding horizontal member 3. This ensures that each building board 41 is securely hung on the horizontal member 3. Silicone is then filled between any two adjacent building boards 41 to form a closed building wall 411. Finally, the air intake module 5 is installed at the bottom of the building wall 411, and the exhaust module 6 is installed at the top of the building wall 411, completing the installation of the building board dry hanging system of the present invention. The construction of the dry hanging system of the building board of the present invention is quite simple and convenient. It not only increases the construction speed and shortens the construction period, but also requires less manpower than the existing construction methods and can reduce the amount of concrete used in the wall 1, thus significantly reducing the construction cost and time.

[0041] In summary, the dry-hanging system of the building board of the present invention forms the building wall 411 through the building board 41, which can effectively block the sunlight from directly hitting the wall 1, and the wall 1 is affixed with the aluminum foil bubble film layer, which can also effectively reflect radiant heat and reduce the solar radiant heat accumulated by the wall 1. The building wall 411, the bottom cover plate 51, the top cover plate 63, and the top sealing plate 62 are spaced from the wall 1 and cooperate to form the air flow channel 412. In addition to being able to effectively block heat conduction, the air intake fan 53 of the air intake module 5 also draws cold air into the air flow channel 412 and the exhaust fan 64 of the exhaust module 6 discharges hot air from the air flow channel 412, allowing the air to form a convection cycle in the air flow channel 412, which is conducive to heat dissipation, and thus can indeed achieve the purpose of the present invention.

[0042] However, the above is only an embodiment of the present invention and should not be used to limit the scope of the present invention. In other words, any simple equivalent changes and modifications made according to the claims and description of the present invention still fall within the scope of the present invention.
