Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-based composite plates, in particular to an aluminum-based composite plate with a multi-layer structure. Background Art

[0002] In the field of modern building decoration, multi-layer aluminum composite panels are a widely used advanced material. The lightweight nature of multi-layer aluminum composite panels makes them an ideal choice for building decoration. Their low density and high strength characteristics allow the building structure to reduce its own load while ensuring strength, thereby reducing the overall weight of the building, helping to reduce the pressure of the building on the foundation and supporting structure, and improving the overall safety of the building.

[0003] The announcement number is CN218171612U. The Chinese patent discloses a multi-layer structure aluminum-based composite panel, which includes an aluminum-based composite panel, and the aluminum-based composite panel includes an aluminum panel layer, a fire-proof sound-absorbing fiber layer, a reinforcement, an aluminum honeycomb layer and an aluminum back panel layer; the multi-layer structure aluminum-based composite panel is arranged by installing a fire-proof sound-absorbing fiber layer and a reinforcement between the aluminum panel layer and the aluminum honeycomb layer, and the reinforcement is embedded on the top of the fire-proof sound-absorbing fiber layer, so as to strengthen the strength of the aluminum-based composite panel while also reducing noise in the room.

[0004] With respect to the above-mentioned related technologies, the composite board has some shortcomings. In actual use, the plug-in column is directly inserted into the sleeve column and lacks any limiting structure. If the composite board is used for a long time, the bonding effect between the composite layers will weaken, and the plug-in column may detach from the sleeve column, thereby reducing the stability of the aluminum-based composite board. Therefore, it is necessary to provide a multi-layer aluminum-based composite board to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-layer aluminum-based composite plate to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A multi-layer aluminum-based composite plate, comprising:

[0008] A back plate, wherein an aluminum honeycomb layer is bonded to the lower surface of the back plate, a reinforcing layer is bonded to the lower surface of the aluminum honeycomb layer, a fireproof sound-absorbing fiber layer is bonded to the lower surface of the reinforcing layer, a panel is bonded to the lower surface of the fireproof sound-absorbing fiber layer, a plurality of positioning columns are fixedly mounted on the upper surface of the panel, a positioning cylinder corresponding to the position and number of the positioning columns is fixedly mounted on the lower surface of the back plate, and the positioning columns are plugged into the positioning cylinders;

[0009] The upper side of the inner wall of the positioning cylinder is provided with symmetrically distributed fixing grooves, two fixing grooves are hinged with clamping blocks, and springs are fixedly connected between the opposite sides of the two clamping blocks and the bottom of the inner wall of the fixing groove;

[0010] The outer wall at the top of the positioning column is provided with symmetrically distributed card slots, and the card slots are card-engaged with the card blocks. The aluminum honeycomb layer, the reinforcement layer and the fireproof and sound-absorbing fiber layer are all provided with positioning holes corresponding to the position and quantity of the positioning tubes.

[0011] Preferably, a second stopper is fixedly mounted on the bottom of the clamping block, and a first stopper is fixedly mounted on one side of the bottom of the inner wall of the fixing groove.

[0012] Preferably, the opposite sides of the two card blocks are inclined, and the card blocks are matched with the card slots.

[0013] Preferably, the reinforcement layer is made of glass fiber reinforced plastic.

[0014] Preferably, one side of the top of the fixing groove is an arc-shaped surface, and the origin of the arc-shaped surface is consistent with the hinge point between the clamping block and the inner wall of the fixing groove.

[0015] Preferably, the inner diameter of the positioning hole matches the outer diameter of the positioning tube.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model uses a back plate, a panel, an aluminum honeycomb layer, a reinforcement layer, a fireproof sound-absorbing fiber layer, a positioning column, a positioning tube, a positioning hole, a clamping block, a fixing groove, a spring and a clamping groove. The clamping connection between the clamping block and the clamping groove can ensure that the positioning column is firmly clamped in the interior of the positioning tube, so that there is a fixed connection relationship between the back plate and the panel. Even if the composite board is used for a long time and the bonding effect of the composite layer between the back plate and the panel is weakened, the multi-layer composite layer can be firmly limited between the back plate and the panel, thereby improving the stability of the aluminum-based composite board. In addition, through the setting of the reinforcement layer, it can provide better rigidity and corrosion resistance, and is relatively cheap at the same time, thereby improving the overall structural strength of the aluminum-based composite board and making it more durable.

[0018] 2. The utility model uses the first stopper and the second stopper in coordination. The first stopper will limit the second stopper to prevent the block from tilting too much toward the inside of the positioning tube, which would cause the positioning column and the positioning tube to not dock smoothly during docking, thereby improving the stability of the structure during use.

[0028] See also Figure 1-4, an embodiment provided by the utility model:

[0029] A multi-layer aluminum-based composite plate, comprising:

[0030] A back plate 1, an aluminum honeycomb layer 3 is bonded to the lower surface of the back plate 1, a reinforcing layer 4 is bonded to the lower surface of the aluminum honeycomb layer 3, a fireproof sound-absorbing fiber layer 5 is bonded to the lower surface of the reinforcing layer 4, a panel 2 is bonded to the lower surface of the fireproof sound-absorbing fiber layer 5, a plurality of positioning columns 6 are fixedly installed on the upper surface of the panel 2, a positioning tube 7 corresponding to the position and number of the positioning columns 6 is fixedly installed on the lower surface of the back plate 1, and the positioning columns 6 are plugged into the positioning tube 7;

[0031] The upper side of the inner wall of the positioning cylinder 7 is provided with symmetrically distributed fixing grooves 10, and two fixing grooves 10 are hinged with clamping blocks 9, and springs 11 are fixedly connected between the opposite sides of the two clamping blocks 9 and the bottom of the inner wall of the fixing grooves 10;

[0032] The outer wall of the top end of the positioning column 6 is provided with symmetrically distributed card slots 14, and the card slots 14 are carded with the card blocks 9. The aluminum honeycomb layer 3, the reinforcement layer 4 and the fireproof and sound-absorbing fiber layer 5 are all provided with positioning holes 8 corresponding to the position and number of the positioning tube 7.

[0033] A second stopper 13 is fixedly mounted on the bottom of the clamping block 9 , and a first stopper 12 is fixedly mounted on one side of the bottom of the inner wall of the fixing groove 10 .

[0034] In one embodiment, the opposite sides of the two clamping blocks 9 are inclined, and the clamping blocks 9 are adapted to the clamping slots 14 , thereby achieving an automatic clamping effect between the clamping blocks 9 and the clamping slots 14 .

[0035] In one of the preferred embodiments, the reinforcing layer 4 is made of glass fiber reinforced plastic, which can provide good rigidity and corrosion resistance and is relatively cheap, thereby improving the overall structural strength of the aluminum-based composite panel and making it more durable.

[0036] In one of the embodiments, one side of the top of the fixing groove 10 is an arc-shaped surface, and the origin of the arc-shaped surface is consistent with the hinge point between the block 9 and the inner wall of the fixing groove 10, so as to avoid the top of the inner wall of the fixing groove 10 hindering the rotation of the block 9 when the block 9 moves into the fixing groove 10, thereby ensuring the stable connection between the positioning column 6 and the positioning cylinder 7.

[0037] In one preferred embodiment, the inner diameter of the positioning hole 8 is matched with the outer diameter of the positioning tube 7 to ensure that the two can be accurately matched, thereby improving the stability and reliability of the composite board.

[0038] The working principle of the utility model is as follows: the parts not involved in the composite board are the same as the prior art or can be implemented by the prior art. When assembling the aluminum-based composite board, the aluminum honeycomb layer 3 is first bonded to the lower surface of the back plate 1, and the positioning holes 8 on the aluminum honeycomb layer 3 are sleeved on the outer wall of the positioning tube 7. By this method, the bonding of the reinforcing layer 4 and the fireproof and sound-absorbing fiber layer 5 is completed in sequence. Finally, the panel 2 is bonded to the lower surface of the fireproof and sound-absorbing fiber layer 5 and the positioning column 6 is inserted from the bottom end of the positioning tube 7. After the positioning column 6 is inserted into the interior of the positioning tube 7, it will contact the inclined surface of the card block 9, pushing the two card blocks 9 to move in opposite directions, so that the card block 9 enters the interior of the fixing groove 10 and squeezes the spring 11 until the positioning column 6 and the positioning tube 7 are completely fixed. Fully engaged, at this time the block 9 will correspond to the position of the slot 14, and the elastic action of the spring 11 will drive the block 9 to be engaged in the slot 14. The engagement of the block 9 with the slot 14 can ensure that the positioning column 6 is firmly engaged in the positioning tube 7, so that there is a fixed connection relationship between the back plate 1 and the panel 2. Even if the composite board has been used for a long time and the bonding effect of the composite layer between the back plate 1 and the panel 2 is weakened, the multi-layer composite layer can be firmly limited between the back plate 1 and the panel 2, thereby improving the stability of the use of the aluminum-based composite board. In addition, through the setting of the reinforcement layer 4, it can provide better rigidity and corrosion resistance, and is relatively cheap at the same time, thereby improving the overall structural strength of the aluminum-based composite board and making it more durable.

[0039] Under the elastic action of the spring 11, a thrust will always be generated on the block 9, and the block 9 will apply this force to the first block 12 through the second block 13. The first block 12 will limit the second block 13 to prevent the block 9 from tilting too much toward the inside of the positioning tube 7, resulting in poor docking between the positioning column 6 and the positioning tube 7, thereby improving the stability of the structure during use.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
