Description

Technical Field

[0001] The invention belongs to the technical field of building exterior wall decoration, and particularly relates to an aluminum single plate for building exterior walls. Background Art

[0002] Building exterior wall decoration refers to the decoration and protection of the building's facade, including the application of materials such as paint, tiles, and aluminum veneers. Aluminum veneers are a commonly used exterior wall decoration material, which is popular because of its light weight, high strength, good corrosion resistance, and easy processing and installation. When using aluminum veneers, they are first formed according to the design requirements, and then fixed to the exterior wall of the building through brackets or fixings, forming a beautiful and durable appearance, while also playing a role in heat preservation and sound insulation. In general, the application of aluminum veneers not only enhances the beauty of the building, but also enhances its functionality and durability.

[0003] The Chinese patent with application number 202410955190.6 discloses a brushed aluminum veneer, including an aluminum veneer frame, a reinforcing component is provided on the top of the aluminum veneer frame, and hanging ears are provided on both sides of the aluminum veneer frame, and a closed component is movably installed on the top of the hanging ears. The present invention uses a reinforcing frame and an elastic airbag to fill a certain amount of inert gas in the reinforcing frame and the elastic airbag, and utilizes the high-pressure environment under the inert filling, and at the same time cooperates with the use of inert gas with low thermal conductivity to achieve thermal insulation reinforcement inside the aluminum veneer frame, and cooperates with polyurethane foam and mineral wool in the filling layer to achieve heat insulation on both sides of the inside and outside during the installation and use of the brushed aluminum plate on the building wall, and has better warmth preservation effect in the cold winter climate, effectively avoiding heat loss, and at the same time in the hot summer environment, it enhances the insulation of external heat, reduces the impact of external environmental heat on the interior, and greatly improves the comprehensive insulation capacity, and has a good use effect.

[0004] When installing aluminum panels, usually the outer fixing frame of the aluminum panels is inserted into the gap and then the fixing frame is fixed to the bracket of the outer wall by bolts. Although this method is more beautiful and can make the gap between adjacent aluminum panels smaller, if a single aluminum panel is damaged, it is impossible to quickly remove and fix the damaged aluminum panel, which makes subsequent maintenance inconvenient; at the same time, if a single bolt fixation becomes loose, the aluminum panel will fall off, causing safety problems; and, for some aluminum panels that can be quickly installed and removed, it is too easy to cause accidental touches, making the installation unstable. Summary of the invention

[0008] Furthermore, a straight slot is penetrated through the side surface of one end of the L-shaped rod, and four abutment rods are evenly fixed in a circumferential direction on the back side of the control panel; the abutment rods correspond to the straight slots one by one, and when the control panel is pressed, the abutment rods can extend into the interior of the corresponding straight slots and approach the middle end of the L-shaped rod.

[0009] Furthermore, when the torsion spring is in a normal state, the L-shaped rod is located in the limit slot, and the threaded end of the limit rod does not extend out of the corresponding threaded opening; when the threaded end of the limit rod extends out of the corresponding threaded opening and the threaded end is threadedly connected to the fixing screw hole, one end of the L-shaped rod extends out of the limit slot.

[0010] Furthermore, a rotation groove is fixedly provided at the inner bottom end of the square shell, and the threaded opening is located outside the rotation groove; a second limiting ring is rotatably connected in the rotation groove, and the sliding rod is located in the middle of the second limiting ring; four through tubes are evenly fixed in an annular direction on the second limiting ring, and the through tubes correspond to the straight slot openings one by one; one end of the through tube is located in the corresponding straight slot opening and is slidably connected to the straight slot opening; the abutment rod can extend into the interior of the corresponding through tube.

[0013] Furthermore, the ends of the clamping cylinder and the abutting rod are both configured with rounded corners.

[0014] Furthermore, when the limiting ring abuts against the limiting plate, the control surface plate and the front surface of the square shell are in the same horizontal plane.

[0015] A method for loading and unloading the above-mentioned building exterior wall aluminum single plate comprises the following steps: S1. Align the threaded opening of the square housing with the fixing screw hole on the corresponding mounting frame, and then rotate the control panel to align the abutment rod of the control panel with the through pipe on the corresponding straight slot; S2. Press the control panel to insert the abutment rod into the interior of the through pipe, then rotate the control panel to drive the second limiting ring to rotate, so that the through pipe slides from the end of the straight slot close to the middle of the L-shaped rod to the end away from the middle of the L-shaped rod. At this time, the through pipe is connected with the circular groove, the threaded end of the limiting rod extends out of the corresponding threaded opening and is screwed with the fixing screw hole, and one end of the L-shaped rod extends out of the limiting slot; S3, loosen the control panel, and under the reset action of the reset spring, the abutment rod leaves the through pipe and the straight slot. At this time, the clamping cylinder in the circular slot extends into the through pipe under the reset action of the second reset spring to clamp and limit the L-shaped rod to complete the installation; S4. When disassembly is required, rotate the control dial to align the abutment rod with the through tube on the corresponding straight slot, and then press the control dial to insert the abutment rod into the inside of the through tube. At this time, the abutment rod squeezes the clamping cylinder into the inside of the circular groove to release the clamping limit; finally, rotate the control dial to release the threaded end of the limit rod from the fixed screw hole. At this time, one end of the L-shaped rod simultaneously extends into the inside of the limit slot to complete the disassembly.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The cooperation between the control panel and the limit fixing mechanism of the present invention can not only quickly fix the square shell, but also limit the adjacent limit fixing mechanisms, thereby preventing the square shell from accidentally falling off. Specifically, by threading the limit rod of the L-shaped rod with the corresponding threaded opening, the threaded end of the limit rod can extend out of the corresponding threaded opening when the L-shaped rod is rotated and be threadedly fixed with the fixing screw hole on the mounting frame. On the basis of this fixing method, by pressing the control panel, the abutment rod can extend into the corresponding straight slot and approach the middle end of the L-shaped rod, so that The L-shaped rod is controlled to rotate by subsequently rotating the control panel, so that the threaded end of the limit rod extends out of the corresponding threaded opening and is screwed with the fixing screw hole, and one end of the L-shaped rod extends out of the limit slot. In this way, the L-shaped rods in the four limit slots of the square shell can be extended to limit the surrounding limit slots, and at the same time, the threaded ends of the limit rods can be extended out of the corresponding threaded openings and screwed with the fixing screw holes on the mounting frame. Even if the square shell becomes loose, it will be limited by the L-shaped rods of the surrounding square shells, thereby preventing the square shell from accidentally falling off.

[0017] (2) The present invention can realize the fast clamping and fixing of the clamping mechanism to the limit fixing mechanism through the cooperation of the second limit ring, the clamping mechanism and the limit fixing mechanism, and can also quickly release the clamping state, so as to facilitate the fast installation and removal of the building exterior wall aluminum veneer, thereby facilitating the maintenance of a single building exterior wall aluminum veneer; and it can also prevent the control panel from being accidentally touched; specifically, when the control panel is rotated to make the threaded end of the limit rod extend out of the corresponding threaded opening and the threaded end is screwed with the fixing screw hole, the rotation of the control panel drives the second limit ring to rotate, and when the through pipe slides from the end of the straight groove opening close to the middle of the L-shaped rod to the end away from the middle of the L-shaped rod, the through pipe is connected with the circular groove, and the control panel is released at this time. The clamping cylinder can automatically extend into the through pipe under the reset action of the second reset spring to clamp and limit the L-shaped rod, thereby realizing fast clamping and fixing of the limit fixing mechanism. When disassembly is required, the control panel is rotated to align the through pipe on the corresponding straight slot of the abutment rod, and then the control panel is pressed to insert the abutment rod into the inside of the through pipe. At this time, the abutment rod squeezes the clamping cylinder into the inside of the circular groove to release the clamping limit. Finally, the control panel is rotated to release the screw connection between the threaded end of the limit rod and the fixing screw hole, so that quick disassembly can be realized, thereby facilitating the maintenance of a single aluminum single panel for the exterior wall of the building; and after the square shell is installed, the aluminum single panel cannot be disassembled by simply rotating or pressing the control panel, thereby preventing the control panel from being accidentally touched.

[0018] (3) The present invention adopts the structural design of the torsion spring, which can not only make the L-shaped rod be located in the limit groove when the square shell is not fixedly installed, thereby reducing the volume of the aluminum plate and facilitating transportation, but also can assist in disassembling the square shell so that the threaded end of the limit rod is unscrewed from the fixed screw hole, thereby facilitating quick disassembly.

[0024] like Figure 1 to Figure 9As shown, an aluminum veneer for building exterior walls includes a square shell 100, a circular notch 120 is provided on the front of the square shell 100, and four side walls of the square shell 100 are provided with limit notches 110, and the circular notch 120 and the four limit notches 110 are connected to each other; a slide rod 140 is fixedly provided in the middle of the interior of the square shell 100, and a limit plate 141 is fixedly provided at the end of the slide rod 140; a control panel 300 is matched with the circular notch 120, and a limit tube 320 is fixedly provided in the middle of the back of the control panel 300, and the limit tube 320 is fixedly provided in the middle of the back of the control panel 300. 0 is fixedly provided with a limit ring 321 inwardly; the limit plate 141 is located inside the limit tube 320 and is slidably connected to the limit tube 320, and the slide bar 140 is slidably connected to the limit ring 321; a return spring 150 is sleeved on the slide bar 140, and the two ends of the return spring 150 are respectively movably abutted against the inner bottom end of the square shell 100 and the limit ring 321; the four limit slots 110 are all installed with a limit fixing mechanism 400, and the control panel 300 is transmission-connected with the limit fixing mechanism 400, which is used to limit and fix the square shell 100.

[0025] The cooperation between the control panel 300 and the limiting fixing mechanism 400 of the present invention can not only quickly fix the square shell 100, but also limit the adjacent limiting fixing mechanisms 400, thereby preventing the square shell 100 from accidentally falling off; the limiting fixing mechanism 400 will be described in detail later.

[0026] It is worth noting that the square housing 100 and the control panel 300 of the present invention are made of aluminum to improve the aesthetics, and the material of the internal structure can be conventionally selected according to the actual situation.

[0027] Furthermore, the limiting and fixing mechanism 400 includes an L-shaped rod 410, the middle part of which is fixedly connected to the limiting rod 420; one end of the limiting rod 420 is a threaded end 421, and four threaded openings 130 are evenly penetrated around the inner bottom end of the square shell 100, and the threaded end 421 of the limiting rod 420 is threadedly connected with the corresponding threaded openings 130; a torsion spring 430 is sleeved on the limiting rod 420, and the two ends of the torsion spring 430 are respectively fixedly connected to the inner bottom end of the square shell 100 and the L-shaped rod 410; a mounting frame 200 is provided on one side of the back side of the square shell 100, and fixing screw holes 210 are opened on the mounting frame 200, and the fixing screw holes 210 correspond one to one with the threaded openings 130.

[0028] It is worth noting that the mounting frame 200 is fixed on the exterior wall of the building. As for the specific fixing method, conventional methods can be selected, such as by pre-embedding or bolts, etc., which will not be described in detail here.

[0029] Furthermore, a straight slot 411 is penetrated through the side surface of one end of the L-shaped rod 410, and four abutment rods 310 are evenly fixed in a circumferential direction on the back side of the control panel 300; the abutment rods 310 correspond to the straight slots 411 one by one, and when the control panel 300 is pressed, the abutment rods 310 can extend into the interior of the corresponding straight slots 411 and approach the middle end of the L-shaped rod 410.

[0030] It is worth mentioning that in the normal state, the abutment rod 310 is not in contact with the straight slot 411, and the control panel 300 will not act on the L-shaped rod 410 even if it rotates randomly. At the same time, since the control panel 300 is made of an opaque material, if the control panel 300 needs to be pressed so that the abutment rod 310 can be accurately inserted into the corresponding straight slot 411, the position needs to be determined by marking, which is a conventional setting and will not be described in detail here.

[0031] Furthermore, when the torsion spring 430 is in a normal state, the L-shaped rod 410 is located in the limiting slot 110, and the threaded end 421 of the limiting rod 420 does not extend out of the corresponding threaded opening 130; when the threaded end 421 of the limiting rod 420 extends out of the corresponding threaded opening 130 and the threaded end 421 is threadedly connected to the fixing screw hole 210, one end of the L-shaped rod 410 extends out of the limiting slot 110.

[0032] The present invention uses a method of threading the limiting rod 420 of the L-shaped rod 410 with the corresponding threaded opening 130, so that when the L-shaped rod 410 is rotated, the threaded end 421 of the limiting rod 420 can extend out of the corresponding threaded opening 130 and be threadedly fixed to the fixing screw hole 210 on the mounting frame 200; based on this fixing method, by pressing the control panel 300, the abutting rod 310 can extend into the corresponding straight slot 411 and approach one end of the middle part of the L-shaped rod 410, so that the L-shaped rod 410 can be controlled to rotate by subsequently rotating the control panel 300, so that the threaded end 421 of the limiting rod 420 extends out of the corresponding threaded opening 130. When the groove 130 and the threaded end 421 are screwed with the fixing screw hole 210, one end of the L-shaped rod 410 extends out of the limiting groove 110; in this way, the L-shaped rod 410 in the four limiting grooves 110 of the square shell 100 can be extended to limit the surrounding limiting grooves 110, and at the same time, the threaded end 421 of the limiting rod 420 can extend out of the corresponding threaded mouth 130 and be screwed and fixed with the fixing screw hole 210 on the installation frame 200; even if the square shell 100 becomes loose, it will be limited by the L-shaped rods 410 of the surrounding square shells 100, thereby preventing the square shell 100 from accidentally falling off.

[0033] Furthermore, a rotating groove 170 is fixedly provided at the inner bottom end of the square shell 100, and the threaded opening 130 is located outside the rotating groove 170; a second limiting ring 500 is rotatably connected in the rotating groove 170, and the sliding rod 140 is located in the middle of the second limiting ring 500; four through tubes 510 are evenly fixed in an annular direction on the second limiting ring 500, and the through tubes 510 correspond one to one with the straight slot openings 411; one end of the through tube 510 is located in the corresponding straight slot opening 411 and is slidably connected to the straight slot opening 411; the abutment rod 310 can extend into the interior of the corresponding through tube 510.

[0034] When the abutment rod 310 extends into the interior of the corresponding through pipe 510, by rotating the control panel 300, the second limiting ring 500 rotates synchronously. At the same time, the through pipe 510 also slides in the straight slot 411 to drive the L-shaped rod 410 and the limiting rod 420 to rotate.

[0035] Furthermore, four circular grooves 160 are evenly opened in an annular direction at the inner bottom end of the rotating groove 170, and a clamping mechanism 600 is provided in the circular groove 160. The clamping mechanism 600 includes a clamping cylinder 610, and the clamping cylinder 610 is slidably connected to the circular groove 160; a second return spring 620 is provided in the circular groove 160, and the two ends of the second return spring 620 are respectively fixedly connected to the clamping cylinder 610 and the circular groove 160; the end of the clamping cylinder 610 movably abuts against the second limiting ring 500.

[0036] Furthermore, the through tube 510 corresponds one-to-one to the clamping cylinder 610; when the second limiting ring 500 rotates to make the through tube 510 slide from one end of the straight slot 411 close to the middle of the L-shaped rod 410 to one end away from the middle of the L-shaped rod 410, the through tube 510 is connected to the circular groove 160.

[0037] The present invention can realize the fastening and fixing of the fastening mechanism 400 by the fastening mechanism 600 through the cooperation of the second limiting ring 500, the clamping mechanism 600 and the limiting fixing mechanism 400, and can also quickly release the clamping state, so as to facilitate the fast installation and removal of the building exterior wall aluminum veneer, thereby facilitating the maintenance of a single building exterior wall aluminum veneer; and, it can also prevent the control panel 300 from being accidentally touched; specifically, when the control panel 300 is rotated to make the threaded end 421 of the limiting rod 420 extend out of the corresponding threaded opening 130 and the threaded end 421 is screwed with the fixing screw hole 210, the rotating control panel 300 drives the second limiting ring 500 to rotate, and when the through pipe 510 slides from one end of the straight groove opening 411 close to the middle of the L-shaped rod 410 to one end away from the middle of the L-shaped rod 410, the through pipe 510 is connected with the circular groove 160, and at this time, the clamping member in the circular groove 160 is released after the control panel 300 is released. The connecting cylinder 610 can automatically extend into the through pipe 510 under the reset action of the second reset spring 620 to clamp and limit the L-shaped rod 410, thereby realizing rapid clamping and fixing of the limit fixing mechanism 400. When disassembly is required, the control panel 300 is rotated to align the through pipe 510 on the corresponding straight slot 411 of the abutting rod 310, and then the control panel 300 is pressed to insert the abutting rod 310 into the inside of the through pipe 510. At this time, the abutting rod 310 squeezes the clamping cylinder 610 into the inside of the circular groove 160 to release the clamping limit. Finally, the control panel 300 is rotated to release the threaded end 421 of the limiting rod 420 from the fixing screw hole 210 to realize rapid disassembly, thereby facilitating the maintenance of a single aluminum single panel for the exterior wall of a building; and, after the square shell 100 is installed, the aluminum single panel cannot be disassembled by simply rotating or pressing the control panel 300, thereby preventing the control panel 300 from being accidentally touched.

[0038] Furthermore, the ends of the clamping cylinder 610 and the abutting rod 310 are both rounded, so that the movement of the clamping cylinder 610 and the abutting rod 310 is facilitated by the rounded design.

[0039] Furthermore, when the limiting ring 321 abuts against the limiting plate 141, the control panel 300 is in the same horizontal plane as the front of the square housing 100. This design improves the overall aesthetics of the aluminum single plate.

[0040] Through the structural design of the torsion spring 430, the present invention can not only position the L-shaped rod 410 in the limiting groove 110 when the square shell 100 is not fixedly installed, thereby reducing the volume of the aluminum plate for convenient transportation, but also assist in unscrewing the threaded end 421 of the limiting rod 420 from the fixing screw hole 210 when disassembling the square shell 100, thereby facilitating quick disassembly.

[0041] A method for loading and unloading the above-mentioned building exterior wall aluminum single plate comprises the following steps: S1, align the threaded opening 130 of the square housing 100 with the fixing screw hole 210 on the corresponding mounting frame 200, and then rotate the control panel 300 to align the abutment rod 310 of the control panel 300 with the through pipe 510 on the corresponding straight slot 411; S2, press the control panel 300 to insert the abutting rod 310 into the interior of the through tube 510, then rotate the control panel 300 to drive the second limiting ring 500 to rotate, so that the through tube 510 slides from the end of the straight slot 411 close to the middle of the L-shaped rod 410 to the end away from the middle of the L-shaped rod 410, at this time, the through tube 510 is connected with the circular groove 160, the threaded end 421 of the limiting rod 420 extends out of the corresponding threaded opening 130 and the threaded end 421 is screwed with the fixing screw hole 210, and one end of the L-shaped rod 410 extends out of the limiting slot 110; S3, release the control panel 300, and under the reset action of the reset spring 150, the abutment rod 310 leaves the through pipe 510 and the straight slot 411. At this time, the clamping cylinder 610 in the circular groove 160 extends into the through pipe 510 under the reset action of the second reset spring 620 to clamp and limit the L-shaped rod 410 to complete the installation; S4. When disassembly is required, rotate the control panel 300 to align the abutment rod 310 with the through tube 510 on the corresponding straight slot 411, and then press the control panel 300 to insert the abutment rod 310 into the inside of the through tube 510. At this time, the abutment rod 310 squeezes the engaging cylinder 610 into the inside of the circular groove 160 to release the engaging limit. Finally, rotate the control panel 300 to release the threaded connection between the threaded end 421 of the limiting rod 420 and the fixing screw hole 210. At this time, one end of the L-shaped rod 410 simultaneously extends into the inside of the limiting slot 110 to complete the disassembly.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and changes without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
