Description

Technical Field

[0001] The invention belongs to the technical field of building material installation, and in particular relates to an installation structure for a U-shaped hyperboloid aluminum square tube and the U-shaped hyperboloid aluminum square tube. Background Art

[0002] Aluminum square tube is a kind of metal decorative material, which is made of aluminum alloy through extrusion, stretching and other processes. It is usually in the shape of a long strip with a square or rectangular cross section. The surface can be treated in a variety of ways, such as spraying, oxidation, etc., to obtain different colors and textures. It is often used for ceiling decoration in public areas such as the lobby, corridor, elevator room, etc. of shopping malls, hotels, office buildings, etc., which can create a simple, atmospheric and modern space atmosphere. Aluminum alloy has high strength and hardness, is not easy to deform or twist, and has good corrosion resistance and oxidation resistance. It can maintain a good appearance and performance for a long time, so it is also widely used in architectural decoration.

[0003] The existing installation method of aluminum square tubes usually adopts the whole installation method. The staff will generally place the aluminum square tube on the keel, align the installation holes on the aluminum square tube with the pre-marked positions on the keel, and then pass the bolts through the holes on the aluminum square tube and the keel, put on the gaskets and nuts, and use a wrench to tighten the nuts to make the aluminum square tube and the keel tightly connected. However, this installation method is not only more troublesome during maintenance, but also when part of the aluminum square tube is damaged and needs to be replaced, it is often necessary to replace the entire tube, which not only increases the material cost, but also reduces the maintenance efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a mounting structure for a U-shaped hyperbolic aluminum square tube and a U-shaped hyperbolic aluminum square tube.

[0005] The technical solution adopted to solve the above technical problems is: an installation structure for U-shaped hyperbolic aluminum square tube, including an aluminum square tube, wherein first installation grooves are axially symmetrically opened at both ends of the aluminum square tube, second installation grooves are axially symmetrically opened at both ends of the aluminum square tube, plug-in grooves are symmetrically opened at both ends of the aluminum square tube, and head installation mechanisms are fixedly installed in the two plug-in grooves respectively; a keel is installed above the aluminum square tube, and a keel mounting frame is fixedly installed at the lower end of the keel, the keel and the keel mounting frame are integrated, and the structure is T-shaped, and a plurality of sets of limit fixing mechanisms are evenly fixed in the keel.

[0006] Through the above technical solution, using an axisymmetrically arranged butt installation mechanism, when a section of the aluminum square tube is damaged and needs to be installed, there is no need to remove the entire aluminum square tube, thus avoiding damage and waste to the undamaged part. Only the damaged section needs to be replaced, which greatly reduces the use of new materials, and the maintenance work can locate the damaged part more quickly and replace it.

[0007] Preferably, an installation cavity is provided in the keel, a fixing groove is provided in the keel mounting frame, a plurality of keel mounting ceilings are uniformly and fixedly connected to the upper end of the keel, a fixing chassis is fixedly connected to one end of the plurality of keel mounting ceilings away from the keel, a plurality of bolt holes are uniformly provided in a circumferential manner on the fixing chassis, and the fixing chassis and the ceiling are fixedly installed through a plurality of expansion screws.

[0008] Through the above technical solution, when installing, the worker inserts a plurality of expansion screws into the bolt holes in sequence to fix the fixing chassis and the ceiling, so that the keel can be firmly fixed on the ceiling.

[0009] Preferably, the limit fixing mechanism includes an installation column slidably connected to the keel, a connection handle is fixedly connected to the upper end of the installation column, a plurality of anti-slip lines are provided on the outer circumference of the connection handle, a connection seat is fixedly connected to the lower end of the installation column, a limit plate is fixedly installed at the upper end of the installation column, the limit plate is slidably connected to the keel, a fixing spring is sleeved on the outer side of the installation column, and both ends of the fixing spring are fixedly connected to the limit plate and the keel respectively, and limit blocks are symmetrically and fixedly connected to both ends of the connection seat.

[0010] Through the above technical solution, when the aluminum square pipe needs to be installed on the keel, the grooved side of the aluminum square pipe is inserted into the keel mounting frame at the lower end of the keel, the connection handle is rotated, the connection seat at the lower end of the installation column driven by the connection handle is rotated out of the fixing groove, the connection handle is released, the fixing spring pushes the limit plate upward, the limit plate drives the installation column and the connection seat to move upward, so that the limit blocks at both ends of the connection seat move upward and closely adhere to the inner wall of the aluminum square pipe, realizing the fixation between the aluminum square pipe and the keel. When the aluminum square pipe needs to be removed, the connection handle is pressed downward and rotated, so that the connection seat at the lower end moves back into the fixing groove.

[0011] Preferably, a friction pad is fixedly connected to the upper end of the limit block, and the friction pad is made of rubber.

[0012] Through the above technical solution, the friction pad on the limit block is closely attached to the aluminum square pipe. Through the frictional force, the aluminum square pipe can be effectively prevented from sliding or displacing on the keel, making the connection between the two more stable, ensuring that the aluminum square pipe can maintain its predetermined position during use and maintaining the stability of the entire structure. At the same time, the friction pad plays a role of buffering and isolation, avoiding direct contact between the limit block and the aluminum square pipe, reducing the possibility of scratches, abrasions or deformations on the surface of the aluminum square pipe caused by collisions and frictions during installation or use, and helping to maintain the appearance integrity and aesthetics of the aluminum square pipe.

[0013] Preferably, the butt mounting mechanism includes an installation box slidably connected to the plug-in slot, a connecting slot is provided on one side of the installation box, a return spring is fixedly connected to one end of the installation box away from the connecting slot, the other end of the return spring is fixedly connected to a fixed block, the fixed block is fixedly connected to the aluminum square tube, and a moving block is fixedly connected to one side of the installation box.

[0014] Through the above technical solution, the two adjacent aluminum square tubes are aligned end to end, and the moving blocks are pushed by both hands at the same time to push the two installation boxes into the plug-in slots. When a section of the aluminum square tube is damaged and needs to be replaced, the pushing blocks are moved by both hands at the same time to rotate the two card blocks to adjust to a parallel state. When the card blocks are rotated and adjusted to a parallel state, the reset spring is no longer subject to the limiting force, and the installation box on the corresponding side can be pulled to slide into the plug-in slot, and then the staff can release the fixation between the two aluminum square tubes.

[0015] Preferably, a connecting base is fixedly connected to the installation box, a limiting ring is fixedly installed on the connecting base, a top block is fixedly connected to one side of the limiting ring, the top block is wedge-shaped away from the limiting ring, a clamping block is rotatably connected to the upper surface of the connecting base, one end of the clamping block is fixedly connected to a fixed long rod, a positioning block is installed on the fixed long rod, a push block is fixedly connected to the side of the fixed long rod away from the clamping block, the push block is slidably connected to the second installation slot, and a spring assembly is installed in the installation box.

[0016] Through the above technical scheme, the positions of the butt mounting mechanisms in two adjacent aluminum square tubes are axially symmetrically arranged. Therefore, when the clamping blocks in the two adjacent aluminum square tubes contact the wedge-shaped surfaces of the other top blocks, they can be rotated and adjusted to a parallel state. When the parallel surfaces of the two clamping blocks complete contact, the two limit circles form a circle, and the fixed long rod rotates back to an inclined state under the spring tension of the spring assembly, thereby fixing and locking the two adjacent aluminum square tubes.

[0017] Preferably, the spring assembly includes a mounting seat fixedly installed with the mounting box, a connecting part rotatably connected in the mounting seat, one end of the connecting part is fixedly connected to the spring box, a moving rod is slidably connected in the spring box, a mounting spring is sleeved on the outside of the moving rod, two ends of the mounting spring are respectively fixedly connected to one side of the moving rod and the inner wall of the spring box, the moving rod is fixedly connected to a connecting head at one end away from the connecting part, a connecting ring is fixedly installed on the connecting head, and the connecting ring is ring-connected to the positioning block.

[0018] Through the above technical scheme, when the clamping block is subjected to pressure tending to a parallel state, the fixed long rod rotates and then drives the moving rod to compress the installing spring through the connecting ring to slide. When the pressure tending to a parallel state disappears, the installing spring can push one side of the moving rod to slide toward the inside of the spring box away from one end of the fixed long rod, so that the connecting head drives the fixed long rod to move, and then the limit ring can rotate and return to the inclined state.

[0019] A U-shaped hyperbolic aluminum square tube comprises an aluminum square tube, both sides of which are arranged in a hyperbolic shape, a plurality of groups of the aluminum square tubes are connected head to tail in a corresponding manner, the aluminum square tube is made of aluminum alloy, and an air stringing slot is opened inside the aluminum square tube, and the air stringing slot is arranged in a curved shape.

[0020] Through the above technical scheme, the curved notch increases the structural complexity and rigidity of the aluminum square tube, so that it can better disperse stress when subjected to wind pressure and other external forces, reduce the possibility of deformation and damage, and improve the stability and durability of the overall structure of the aluminum square tube. The curved notch can buffer and disperse the airflow, reduce the vibration and noise caused by the direct impact of the airflow on the notch edge and the inner wall of the aluminum square tube. Compared with the straight notch, the curved notch can effectively reduce wind noise.

[0021] The beneficial effects of the present invention are as follows: (1) The present invention is designed with a matching butt installation mechanism. When a certain section of the aluminum square tube is damaged and needs to be installed, there is no need to dismantle the entire aluminum square tube, thus avoiding damage and waste to the undamaged part. Only the damaged section needs to be replaced, which greatly reduces the use of new materials. The repair work can locate the damaged part more quickly and replace it, reducing many links in the removal and reinstallation process, such as disassembling fixings and carrying long strips of aluminum square tubes. This can effectively shorten the overall time of the repair work, enable the building space to be restored to normal use more quickly, and make the operation more convenient and efficient. (2) The present invention is designed with a limit fixing mechanism. When a worker turns the connecting handle, the connecting handle drives the connecting seat at the lower end of the installation column to rotate out of the fixing groove. When the connecting handle is released, the fixing spring pushes the limit plate upward, thereby causing the limit blocks at both ends of the connecting seat to move upward and fit tightly against the inner wall of the aluminum square tube, thereby fixing the aluminum square tube to the keel. When the aluminum square tube needs to be removed, the connecting handle is pressed downward and rotated in the opposite direction to move the connecting seat at the lower end back into the fixing groove. There is no need to tighten the bolts one by one as in bolt fixing, which greatly reduces the installation time and workload, improves the installation efficiency, and keeps the appearance of the material neat.

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] As Figures 1 - 2As shown in the figure, an installation structure for U-shaped hyperbolic aluminum square pipes in this embodiment includes an aluminum square pipe 1. First installation grooves 12 are symmetrically opened at both ends of the aluminum square pipe 1, second installation grooves 13 are symmetrically opened at both ends of the aluminum square pipe 1, and insertion grooves 11 are symmetrically opened at both ends of the aluminum square pipe 1. Opposite installation mechanisms 4 are fixedly installed in the two insertion grooves 11 respectively. A keel 2 is installed above the aluminum square pipe 1. A keel installation frame 26 is fixedly installed at the lower end of the keel 2. The keel 2 and the keel installation frame 26 are integrally arranged, and the structure is in a T shape. A plurality of groups of limit fixing mechanisms 3 are uniformly and fixedly arranged in the keel 2. By using the axially symmetrically arranged opposite installation mechanisms 4, when a certain section of the aluminum square pipe is damaged and needs to be installed, there is no need to remove the entire aluminum square pipe, avoiding damage and waste to the undamaged part. Only the damaged section needs to be replaced, greatly reducing the usage amount of new materials, and the maintenance work can more quickly locate the damaged part and replace it. An installation cavity 24 is opened in the keel 2, a fixing groove 25 is opened in the keel installation frame 26, a plurality of groups of keel installation ceilings 21 are uniformly and fixedly connected to the upper end of the keel 2, a fixing chassis 22 is fixedly connected to one end of the plurality of groups of keel installation ceilings 21 away from the keel 2, a plurality of groups of bolt holes 23 are uniformly opened in a circumferential manner on the fixing chassis 22, and the fixing chassis 22 and the ceiling are fixedly installed through a plurality of expansion screws. When installing, the worker inserts the plurality of expansion screws into the bolt holes 23 in sequence to fix the fixing chassis 22 and the ceiling, so that the keel 2 can be firmly fixed on the ceiling.

[0026] As Figures 1 - 4As shown, the limit fixing mechanism 3 includes a mounting post 30 that is slidably connected to the keel 2. The upper end of the mounting post 30 is fixedly connected to a connection handle 31. Multiple groups of anti-slip lines are provided on the outer circumference of the connection handle 31. The lower end of the mounting post 30 is fixedly connected to a connection seat 33. A limit plate 32 is fixedly installed at the upper end of the mounting post 30. The limit plate 32 is slidably connected to the keel 2. A fixing spring 36 is sleeved on the outer side of the mounting post 30. The two ends of the fixing spring 36 are respectively fixedly connected to the limit plate 32 and the keel 2. The two ends of the connection seat 33 are symmetrically and fixedly connected with limit blocks 34. When the aluminum square tube 1 needs to be installed on the keel 2, the grooved side of the aluminum square tube 1 is aligned with the keel mounting frame 26 at the lower end of the keel 2 and inserted. The connection handle 31 is rotated. The connection handle 31 drives the connection seat 33 at the lower end of the mounting post 30 to rotate out of the fixing groove 25. The connection handle 31 is released. The fixing spring 36 pushes the limit plate 32 upward. The limit plate 32 drives the mounting post 30 and the connection seat 33 to move upward. Thus, the limit blocks 34 at both ends of the connection seat 33 move upward and closely adhere to the inner wall of the aluminum square tube 1, realizing the fixation between the aluminum square tube 1 and the keel 2. When the aluminum square tube 1 needs to be removed, the connection handle 31 is pressed downward and rotated, so that the connection seat 33 at the lower end moves back into the fixing groove 25; a friction pad 35 is fixedly connected to the upper end of the limit block 34. The friction pad 35 is made of rubber. The friction pad 35 on the limit block 34 is closely attached to the aluminum square tube. Through the frictional force, the aluminum square tube 1 can be effectively prevented from sliding or displacing on the keel 2, making the connection between the two more stable, ensuring that the aluminum square tube 1 can maintain a predetermined position during use, maintaining the stability of the entire structure. At the same time, the friction pad 35 plays a role of buffering and isolation, avoiding the direct contact between the limit block 34 and the aluminum square tube 1, reducing the possibility of scratches, abrasions or deformations on the surface of the aluminum square tube 1 caused by collisions and frictions during installation or use, and helping to maintain the appearance integrity and beauty of the aluminum square tube 1.

[0027] As Figures 1 - 10As shown, the butt mounting mechanism 4 includes a mounting box 40 that is slidably connected to the plug-in slot 11, a connecting slot 41 is provided on one side of the mounting box 40, and a return spring 43 is fixedly connected to one end of the mounting box 40 away from the connecting slot 41, and the other end of the return spring 43 is fixedly connected to a fixed block 44, and the fixed block 44 is fixedly connected to the aluminum square tube 1, and a moving block 42 is fixedly connected to one side of the mounting box 40. The two adjacent aluminum square tubes 1 are aligned end to end, and the moving blocks 42 are pushed by both hands at the same time to push the two mounting boxes 40 out of the plug-in slot 11. When a certain section of the aluminum square tube 1 is damaged and needs to be replaced, the pushing blocks 410 are pushed by both hands at the same time so that the two clamping blocks 47 are rotated and adjusted to a parallel state. When the clamping blocks 47 are rotated and adjusted to a parallel state, the return spring 43 is no longer subject to the limiting force, and the mounting box 40 on the corresponding side can be pulled to slide into the plug-in slot 11, and then the staff can release the fixation between the two aluminum square tubes 1; a connecting base 45 is fixedly connected to the mounting box 40, and the connecting base A limit ring 46 is fixedly installed on the upper surface of the connecting base 45, and a top block 411 is fixedly connected to one side of the limit ring 46. The top block 411 is wedge-shaped away from the limit ring 46. A clamping block 47 is rotatably connected to the upper surface of the connecting base 45. A fixed long rod 48 is fixedly connected to one end of the clamping block 47. A positioning block 49 is installed on the fixed long rod 48. A push block 410 is fixedly connected to the side of the fixed long rod 48 away from the clamping block 47. The push block 410 is slidably connected to the second mounting groove 13, and the mounting box 40 is installed in the mounting box 40. A spring assembly 5 is provided, and the positions of the butt mounting mechanisms 4 in the two adjacent aluminum square tubes 1 are axially symmetrical. Therefore, the clamping blocks 47 in the two adjacent aluminum square tubes 1 can be rotated and adjusted to a parallel state when they contact the wedge-shaped surface of the other top block 411. When the parallel surfaces of the two clamping blocks 47 complete contact, the two limit circles 46 form a circle, and the fixed long rod 48 rotates and returns to an inclined state under the spring tension of the spring assembly 5, thereby fixing and locking the two adjacent aluminum square tubes 1.

[0028] like Figures 1 - 11As shown in the figure, the spring assembly 5 includes a mounting seat 50 fixedly installed on the mounting box body 40. A connecting portion 51 is rotatably connected inside the mounting seat 50. One end of the connecting portion 51 is fixedly connected to a spring box body 52. A moving rod 53 is slidably connected inside the spring box body 52. An installation spring 54 is sleeved outside the moving rod 53. Both ends of the installation spring 54 are fixedly connected to one side of the moving rod 53 and the inner wall of the spring box body 52 respectively. One end of the moving rod 53 away from the connecting portion 51 is fixedly connected to a connecting head 55. A connecting ring 56 is fixedly installed on the connecting head 55. The connecting ring 56 is loop-connected with the positioning block 49. When the clamping block 47 is subjected to a pressure tending to a parallel state, the fixed long rod 48 rotates and then drives the moving rod 53 to compress the installation spring 54 and slide through the connecting ring 56. When the pressure tending to the parallel state disappears, the installation spring 54 can push one side of the moving rod 53 to slide inside the spring box body 52 away from one end of the fixed long rod 48, so that the connecting head 55 drives the fixed long rod 48 to move. Furthermore, the limiting ring 46 can rotate and return to an inclined state.

[0029] As Figure 12 shown, a U-shaped hyperbolic aluminum square pipe includes an aluminum square pipe. Both sides of the aluminum square pipe 1 are arranged in a hyperbolic shape. Multiple groups of aluminum square pipes 1 are connected end to end. The aluminum square pipe 1 is made of aluminum alloy. An air passage slot is opened inside the aluminum square pipe 1, and the air passage slot is arranged in a curved shape. The curved slot increases the structural complexity and stiffness of the aluminum square pipe 1, enabling it to better disperse stress when bearing wind pressure and other external forces, reducing the possibility of deformation and damage, and improving the stability and durability of the overall structure of the aluminum square pipe 1. Moreover, the curved slot can play a role in buffering and dispersing air flow, reducing the vibration and noise generated by the air flow directly impacting the edge of the slot and the inner wall of the aluminum square pipe 1. Compared with a straight slot, the curved slot can effectively reduce wind noise.

[0030] The working principle of this embodiment is as follows. When it is necessary to splice and combine the aluminum square pipes 1, place two aluminum square pipes 1 to be spliced in the same horizontal position, and name them aluminum square pipe 1 one and aluminum square pipe 1 two respectively. Align the heads and tails of the aluminum square pipe 1 one and the aluminum square pipe 1 two, and simultaneously push the moving blocks 42 with both hands to push the two mounting box bodies 40 out of the insertion slot 11. Since the positions of the head-to-head installation mechanisms 4 inside the aluminum square pipe 1 one and the aluminum square pipe 1 two are axially symmetrically arranged, when the clamping blocks 47 inside the aluminum square pipe 1 one and the aluminum square pipe 1 two contact the wedge-shaped surfaces of the opposing top blocks 411, they both rotate and adjust to a parallel state. When the parallel surfaces of the two clamping blocks 47 are in contact, the two limiting rings 46 enclose a circle, and the fixed long rod 48 rotates and returns to an inclined state under the spring tension of the spring assembly 5, thereby fixedly clamping the aluminum square pipe 1 one and the aluminum square pipe 1 two. Repeating this operation can infinitely connect multiple groups of aluminum square pipes 1. When a certain section of the aluminum square tube 1 is damaged and needs to be replaced, the push block 410 is pushed by both hands at the same time, so that the two clamping blocks 47 are rotated and adjusted to a parallel state. When the clamping blocks 47 are rotated and adjusted to a parallel state, the return spring 43 is no longer subject to the limiting force, and the installation box 40 on the corresponding side can be pulled to slide into the plug-in slot 11, and then the staff can release the fixation between the two aluminum square tubes 1; When the aluminum square tube 1 needs to be installed on the keel 2, align the slotted side of the aluminum square tube 1 with the keel mounting frame 26 at the lower end of the keel 2 and insert it, rotate the connecting handle 31, and the connecting handle 31 drives the connecting seat 33 at the lower end of the mounting column 30 to rotate out of the fixing groove 25, loosen the connecting handle 31, and the fixing spring 36 pushes the limit plate 32 upward, and the limit plate 32 drives the mounting column 30 and the connecting seat 33 to move upward, so that the limit blocks 34 at both ends of the connecting seat 33 move upward and close to the inner wall of the aluminum square tube 1, so that the aluminum square tube 1 and the keel 2 are fixed. When the aluminum square tube 1 needs to be removed, press down and rotate the connecting handle 31 in the opposite direction to move the connecting seat 33 at the lower end back into the fixing groove 25.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
