Description

Technical Field

[0001] This invention belongs to the field of building decoration, specifically a prefabricated wall panel and its installation and positioning method. Background Technology

[0002] With the rapid development of industrialized construction, prefabricated buildings, due to their advantages such as factory prefabrication, on-site assembly, green environmental protection, and energy efficiency, have become a core direction for the transformation and development of the construction industry. Prefabricated wall panels, as core components of enclosure and partition structures, are widely used in various engineering projects, including residential and public buildings. Their installation quality and assembly efficiency directly affect the construction progress, construction cost, and overall performance of the entire building project. The core requirement for installing prefabricated wall panels is to connect the prefabricated wall panels to the building foundation wall to meet the various functional requirements of load-bearing, thermal insulation, and sound insulation during the building's use. Currently, the industry commonly uses multi-position bolt fixing for the fixed connection between prefabricated wall panels and the foundation wall. This method has the following drawbacks: This method requires pre-setting installation holes on the base wall, opening matching holes at corresponding positions on the wall panel, then inserting bolts through the holes in the wall panel and the base wall, and finally tightening them with nuts to achieve fixation, resulting in low installation efficiency. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides a prefabricated wall panel and an installation and positioning method, which effectively solves the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated wall panel, comprising a decorative wall panel, wherein an assembly assembly is provided on the back of the decorative wall panel; The assembly includes two fixed columns fixedly installed on the back of the decorative wall panel. An adsorption end plate is installed on the end of the fixed column away from the decorative wall panel. A rotating plate is rotatably installed on the outside of the fixed column. A rotating cylinder is fixedly installed on the side of the rotating plate away from the decorative wall panel. A limit block is fixedly installed on the inner top wall of the rotating cylinder. A pre-assembly component is provided on the inner side of the rotating cylinder. The pre-assembly component is bolted to the base wall and is used to connect the base wall to the fixed column. A toothed ring is mounted on the circumference of the rotating cylinder, and a rotation drive component is provided between the two toothed rings.

[0005] Preferably, two limiting plates are symmetrically installed on the fixed column, and the two limiting plates limit the rotating plate. The limiting plate on the side away from the decorative wall panel has a positioning block installed at an equal angle on the side away from the decorative wall panel, and a roller is rotatably installed on the inner side of the limiting block.

[0006] Preferably, the rotation drive component includes a fixed box fixedly installed on the back of the decorative wall panel. The fixed box is located between two fixed columns. Toothed plates are symmetrically installed on both sides of the fixed box. The two toothed plates are respectively engaged with toothed rings on the side closest to each other. A connecting plate is fixedly installed between the two toothed plates and is located above the fixed box.

[0007] Preferably, the fixed box has an air storage chamber inside, and a piston block is movably installed inside the air storage chamber. The outer wall of the piston block is in close contact with the inner wall of the air storage chamber. Push rods are symmetrically installed on the top of the piston block, and the top of the push rods extends through to the top of the fixed box. The top of the push rods is fixedly connected to the connecting plate.

[0008] Preferably, an air inlet pipe is fixedly installed at the bottom of the fixed box, and the air inlet pipe is connected to the air storage chamber located below the piston block. A first one-way valve is installed inside the air inlet pipe.

[0009] Preferably, the pre-assembled component includes a fixed cylinder, on the end face of which positioning grooves are formed at equal angles, and the positioning grooves correspond one-to-one with the positioning blocks. A negative pressure groove is formed inside the fixed cylinder, and an insertion groove is formed at one end of the negative pressure groove. The diameter of the insertion groove is larger than the diameter of the negative pressure groove, and the diameter of the insertion groove is the same as the diameter of the adsorption end plate.

[0010] Preferably, the top of the fixed cylinder is symmetrically equipped with limiting baffles, and a limiting gap is formed between the two limiting baffles. After the rotating cylinder is inserted into the outside of the fixed cylinder, the adsorption end plate is inserted into the insertion groove, so that the outer wall of the roller contacts the bottom wall of the fixed cylinder. After the rotating cylinder rotates, the limiting block is locked into the limiting gap. An exhaust pipe is fixedly installed at the bottom of the fixed cylinder. The exhaust pipe is connected to the negative pressure groove, and a second one-way valve is installed inside the exhaust pipe.

[0011] Preferably, a mounting plate is fixedly installed at the end of the fixed cylinder away from the insertion groove, and bolt positioning holes are opened at equal angles on the mounting plate.

[0012] A preferred method for installing and positioning prefabricated wall panels is as follows: S1. Pre-installed components: Install the two fixing cylinders onto the foundation wall with bolts, ensuring that the two fixing cylinders correspond one-to-one with the two fixing columns; S2. Inhalation pump connection: Take the dual-head inhalation pump, connect the two nozzles to the exhaust pipes at the bottom of the two fixed tubes through hoses, and connect the exhaust tail pipe of the inhalation pump to the inhalation pipe through a hose. S3. Positioning Installation: Insert the two adsorption end plates on the back of the decorative wall panel into the two insertion slots respectively, and make the positioning block correspondingly inserted into the positioning slot to achieve positioning; S4. Assembly and installation: Turn on the air pump to drive the air in the negative pressure groove to be discharged and output to the air storage chamber, so that negative pressure is generated in the negative pressure groove to achieve negative pressure fixation, and push the toothed plate to move upward, drive the positioning groove to rotate, so that the limit block is locked into the limit gap, and complete the fixed assembly and installation.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention involves inserting two adsorption end plates on the back of a decorative wall panel into two insertion slots, and positioning them using a positioning block and positioning slot. A vacuum is created by venting air outward from the inner cavity of the negative pressure slot, causing the fixing cylinder and the adsorption end plates to be fixed by negative pressure adsorption, thus achieving the assembly and installation of the decorative wall panel and facilitating installation. This invention, by having two toothed plates meshing with two toothed rings on one side close to each other, can limit the decorative wall panel while simultaneously driving the piston block to move upward, causing the rotating cylinder to rotate, which allows the limiting block to engage in the limiting gap between the two limiting baffles, further improving the limiting effect and enhancing the fixing stability. This invention connects the two suction heads of a dual-suction pump to two exhaust pipes, and connects the exhaust tail pipe of the suction pump to the intake pipe. The suction pump drives the air in the negative pressure groove to be discharged to form a negative pressure fixation, while the air is output to the air storage chamber, pushing the piston block to move upward, realizing rotation limit and improving installation efficiency.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] Example 1, by Figures 1-2 The present invention includes a prefabricated wall panel, comprising a decorative wall panel 1, wherein an assembly assembly 2 is provided on the back of the decorative wall panel 1; Depend on Figure 3 As shown, the assembly component 2 includes two fixed posts 201 fixedly installed on the back of the decorative wall panel 1. An adsorption end plate 204 is installed at the end of the fixed post 201 away from the decorative wall panel 1. A rotating plate 205 is rotatably installed on the outside of the fixed post 201. A rotating cylinder 206 is fixedly installed on the side of the rotating plate 205 away from the decorative wall panel 1. A limit block 207 is fixedly installed on the inner top wall of the rotating cylinder 206. A pre-assembly component 3 is provided on the inner side of the rotating cylinder 206. The pre-assembly component 3 is bolted to the base wall and is used to connect the base wall to the fixed post 201.

[0018] Depend on Figures 5-6The pre-assembled component 3 includes a fixed cylinder 303. Positioning grooves 306 are formed at equal angles on the end face of the fixed cylinder 303, corresponding one-to-one with positioning blocks 203. A negative pressure groove 305 is formed inside the fixed cylinder 303, and an insertion groove 304 is formed at one end of the negative pressure groove 305. The diameter of the insertion groove 304 is larger than the diameter of the negative pressure groove 305, and the diameter of the insertion groove 304 is the same as the diameter of the adsorption end plate 204. The two adsorption end plates 204 on the back of the decorative wall panel 1 are respectively inserted into the two insertion grooves 304 and positioned by the positioning blocks 203 and the positioning grooves 306. A vacuum is formed by venting air outwards from the inner cavity of the negative pressure groove 305, causing the fixed cylinder 303 and the adsorption end plates 204 to be fixed by negative pressure adsorption, thus facilitating the assembly and installation of the decorative wall panel 1. Limiting baffles 307 are symmetrically installed at the top of the fixed cylinder 303. A limiting gap 308 is formed between the baffles 307. After the rotating cylinder 206 is fitted onto the outside of the fixed cylinder 303, the adsorption end plate 204 is inserted into the insertion groove 304, so that the outer wall of the roller 208 contacts the bottom wall of the fixed cylinder 303. After the rotating cylinder 206 rotates, the limiting block 207 is locked into the limiting gap 308. An exhaust pipe 309 is fixedly installed at the bottom end of the fixed cylinder 303. The exhaust pipe 309 is connected to the negative pressure groove 305. A second one-way valve 310 is installed inside the exhaust pipe 309. The second one-way valve 310 is used to restrict air from being discharged from the negative pressure groove 305 to the external environment through the exhaust pipe 309, so that air cannot enter the negative pressure groove 305 from the external environment through the exhaust pipe 309. An installation plate 301 is fixedly installed at the end of the fixed cylinder 303 away from the insertion groove 304. Bolt positioning holes 302 are opened at equal angles on the installation plate 301.

[0019] Depend on Figure 3 As shown, a toothed ring 209 is mounted circumferentially on the rotating cylinder 206, and a rotation drive component 210 is provided between the two toothed rings 209.

[0020] Two limiting plates 202 are symmetrically installed on the fixed column 201. The two limiting plates 202 limit the rotating plate 205. The limiting plate 202 on the side away from the decorative wall panel 1 has a positioning block 203 installed at an equal angle on the side away from the decorative wall panel 1. A roller 208 is rotatably installed on the inner side of the limiting block 207.

[0021] Depend on Figure 4The rotating drive component 210 includes a fixed housing 2101 fixedly installed on the back of the decorative wall panel 1. The fixed housing 2101 is located between two fixed posts 201. Toothed plates 2106 are symmetrically installed on both sides of the fixed housing 2101. The two toothed plates 2106 are respectively engaged with toothed rings 209 on their respective sides. A connecting plate 2105 is fixedly installed between the two toothed plates 2106. The connecting plate 2105 is located above the fixed housing 2101. An air storage chamber 2102 is opened inside the fixed housing 2101. A piston block 2103 is installed inside the gas storage chamber 2102. The outer wall of the piston block 2103 is in close contact with the inner wall of the gas storage chamber 2102. A push rod 2104 is symmetrically installed on the top of the piston block 2103. The top of the push rod 2104 extends to the top of the fixed box 2101 and is fixedly connected to the connecting plate 2105. Two toothed plates 2106 are respectively engaged with two toothed rings 209 on one side of each other. This can limit the movement of the decorative wall panel 1. When the piston block 2103 is driven to move upward, it drives the rotating... Rotating the moving cylinder 206 allows the limiting block 207 to engage in the limiting gap 308 between the two limiting baffles 307, further enhancing the limiting effect and improving the fixing stability. An air inlet pipe 2107 is fixedly installed at the bottom of the fixed box 2101. The air inlet pipe 2107 is connected to the air storage chamber 2102 located below the piston block 2103. The two suction heads of the dual-suction pump are connected to the two exhaust pipes 309 respectively, while the exhaust tailpipe of the suction pump is connected to the air inlet pipe 2107. The suction pump drives the negative pressure groove 30. While the internal air is discharged to form a negative pressure fixation, the air is output to the air storage chamber 2102, pushing the piston block 2103 to move upward, realizing rotation limit and improving installation efficiency. The air inlet pipe 2107 is equipped with a first one-way valve 2108. The first one-way valve 2108 is used to restrict the air from entering the air storage chamber 2102 from the outside through the air inlet pipe 2107, so that the air cannot be discharged from the air storage chamber 2102 to the outside environment through the air inlet pipe 2107.

[0022] Working principle: During use, the two fixing cylinders 303 are installed on the base wall by the cooperation of the bolts with the bolt positioning holes 302 on the mounting plate 301, and the distance between the two fixing cylinders 303 corresponds one-to-one with the position of the two fixing posts 201 on the back of the decorative wall panel 1. Take a dual-nozzle suction pump, connect the two suction nozzles to the exhaust pipes 309 at the bottom of the two fixed cylinders 303 respectively through hoses, and connect the exhaust tail pipe of the suction pump to the intake pipe 2107 through a hose. Then, the decorative wall panel 1 is installed. During installation, the two rotating cylinders 206 are respectively fitted onto the outside of the two fixed cylinders 303, so that the two adsorption end plates 204 are respectively inserted into the two insertion slots 304, and the outer wall of the adsorption end plate 204 is in close contact with the inner wall of the insertion slot 304. The positioning block 203 is correspondingly inserted into the positioning slot 306 to achieve positioning. At this time, the roller 208 on the inner side of the limiting block 207 on the bottom wall of the rotating cylinder 206 contacts the bottom wall of the fixed cylinder 303. Then the suction pump is turned on. Under the action of the suction pump, the air inside the two negative pressure grooves 305 is extracted and input into the air storage chamber 2102. When the air inside the negative pressure grooves 305 is discharged, it generates negative pressure suction on the adsorption end plate 204 to achieve negative pressure fixation. After air is input into the space below the piston block 2103 inside the air storage chamber 2102, the air pressure below the piston block 2103 increases, pushing the piston block 2103 to move upward, which in turn drives the two toothed plates 2106 on both sides to move upward. The two toothed plates 2106 are respectively engaged with the two toothed rings 209 on one side, thereby driving the rotating cylinder 206 to rotate. When the piston block 2103 moves upward to the limit position, it drives the two rotating cylinders 206 to rotate half a turn, so that the roller 208 moves along the outer wall of the fixed cylinder 303 to the top of the fixed cylinder 303, so that the limiting block 207 is engaged in the limiting gap 308 between the two limiting baffles 307, completing the installation. After installation, the two toothed plates 2106 are engaged with the two toothed rings 209 on one side of each other. Through the cooperation of the adsorption end plate 204 and the insertion groove 304, and the cooperation of the positioning block 203 and the positioning groove 306, the longitudinal plane limit and the parallel plane limit are achieved. The limiting block 207 enters the limiting gap 308 between the two limiting baffles 307 to achieve the perpendicular plane limit, thereby improving the installation stability. The exhaust pipe 309 is equipped with a second one-way valve 310. The second one-way valve 310 is used to restrict air from being discharged from the negative pressure tank 305 to the external environment through the exhaust pipe 309, thus preventing air from entering the negative pressure tank 305 from the external environment through the exhaust pipe 309. The intake pipe 2107 is equipped with a first one-way valve 2108. The first one-way valve 2108 is used to restrict air from entering the air storage chamber 2102 from the outside through the intake pipe 2107, thus preventing air from being discharged from the air storage chamber 2102 to the external environment through the intake pipe 2107, thereby ensuring the stability of the negative pressure and the locking stability of the limit block 207. After installation, simply pull out the three hoses connected to the negative pressure pump.
