Description

Technical Field

[0001] This utility model belongs to the field of building decoration technology, and specifically relates to a large-area prefabricated aluminum panel ceiling structure. Background Technology

[0002] Currently, Chinese utility model patent CN217998578U discloses a prefabricated design structure for large-area aluminum panel ceilings. However, other problems still exist in its use. The main disadvantage of traditional large-area prefabricated aluminum panel ceilings is their poor construction tolerance. When cumulative errors occur in the installation of secondary keels, on-site cutting or rework adjustment is often required. This not only destroys the standardized characteristics of the components but also prolongs the construction period, affects the overall flatness and aesthetics, and significantly increases the cost of manual adjustment. In addition, the rigid connection method of traditional large-area prefabricated aluminum panel ceilings requires extremely high construction precision. When there is a millimeter-level deviation in the installation of primary and secondary keels, it is easy to cause misalignment of aluminum panel installation holes or uneven joints. Long-term use may cause ceiling deformation or cracking of the panel surface. Especially in large-span designs, it will significantly increase the construction difficulty and later maintenance costs. In order to solve the problems mentioned above, we propose a large-area prefabricated aluminum panel ceiling structure. Utility Model Content

[0003] The purpose of this utility model is to provide a large-area prefabricated aluminum panel ceiling structure, which has the advantages of adjustable error and high construction adaptability.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a large-area prefabricated aluminum panel ceiling structure, including a secondary keel, threaded holes are provided on both sides of the bottom of the secondary keel, and a limit bolt is connected to the internal threads of two adjacent threaded holes. A limit groove is slidably sleeved on the bottom of the surface of the limit bolt, and an adjustment plate is provided on the outside of the limit groove. An adjustment mechanism is provided at the bottom of the secondary keel.

[0005] The above technical solution involves the following steps: During installation, first connect the main bolt of the top expansion joint, then connect the main bolt to the flange, connect the flange to the secondary bolt, and connect the secondary bolt to the J-mount. Install the top expansion joint on the roof. Place the main keel on the J-mount and fix it with bolts. Install the secondary keel at the bottom of the main keel. Fix the adjusting plate at the bottom of the opposite end of the two secondary keels with limit bolts. Do not tighten the limit bolts completely. After the secondary keel installation of the overall ceiling structure is completed, observe whether there are any errors that cause gaps between the secondary keels. If there are gaps, allow the limit bolts to slide through the limit grooves on the adjusting plate to align the two secondary keels. Tighten the limit bolts to fix them. This improves the construction tolerance of the prefabricated aluminum panel ceiling. The flexible displacement of the adjusting groove compensates for the installation error of the secondary keel, avoiding rework and cutting caused by dimensional deviations in traditional solutions, while maintaining the universality of standardized components. This mechanical adjustment mechanism improves on-site installation efficiency while ensuring structural strength and effectively solves the common problem of tolerance accumulation in prefabricated buildings.

[0006] The present invention is further configured such that the adjustment structure includes a slider, the slider is welded to the left side of the top of the secondary keel, the surface of the slider is slidably connected with a groove, the outside of the groove is provided with a main keel, and the surface of the main keel is sleeved with a J-shaped hanger.

[0007] The above technical solution employs an adjustment mechanism. After the main keel is installed, the slider on the secondary keel is inserted into the groove of the main keel, and the position of the secondary keel is adjusted by sliding. After the entire secondary keel is set up, the spacing between the secondary keels is observed to see if the difference is too large. If there is a significant difference, the secondary keel is adjusted by sliding. After adjustment, it is bolted and fixed. This significantly improves the construction adaptability of prefabricated aluminum panel ceilings and simplifies the on-site leveling process. Workers only need to adjust the level of the main keel, and the secondary keel can be positioned by sliding and self-adapting. This significantly reduces the dependence on construction precision and is especially suitable for the efficient installation of complex shapes such as large spans.

[0008] The present invention is further configured such that a secondary screw is threadedly connected to the top of the J-shaped pendant.

[0009] The above technical solution involves setting up a secondary keel to connect the J-mount and the top flange.

[0010] The present invention is further configured such that a flange is threadedly connected to the top of the surface of the secondary screw.

[0011] The above technical solution allows for adjustment of the ceiling height by incorporating flanges.

[0012] The present invention is further configured such that a main screw is threadedly connected to the top of the flange.

[0013] The above technical solution allows for the connection of the flange and the top explosion-proof valve by setting a main screw.

[0014] The present invention is further configured such that the top of the main screw is threaded with a top explosion.

[0015] The above technical solution allows the suspended ceiling to be fixed to the top of the house by setting up a top explosion mechanism.

[0016] The present invention is further configured such that an aluminum plate is bolted to the side opposite to the secondary keel located on one side.

[0017] The above technical solution involves installing aluminum panels to enclose the top of the suspended ceiling.

[0018] The present invention is further configured such that the length of the suspended ceiling is not more than 1.5 meters.

[0019] The above technical solution is adopted: the height is set to no more than 1.5 meters, and if it exceeds this, additional reinforcement structures are required.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model improves the construction tolerance of prefabricated aluminum panel ceilings and compensates for the installation error of secondary keel by adjusting the flexible displacement of the groove. This avoids the rework and cutting caused by dimensional deviations in traditional solutions and maintains the universality of standardized components. This mechanical adjustment mechanism improves on-site installation efficiency while ensuring structural strength and effectively solves the common problem of tolerance accumulation in prefabricated buildings.

[0022] 2. This utility model greatly improves the construction adaptability of prefabricated aluminum panel ceilings and simplifies the on-site leveling process. Workers only need to adjust the level of the main keel, and the secondary keel can be positioned by sliding and self-adapting, which significantly reduces the dependence on construction accuracy. It is especially suitable for efficient installation of complex shapes such as large spans. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] Referring to the figure, a large-area prefabricated aluminum panel ceiling structure includes a secondary keel 1. Threaded holes 3 are opened on both sides of the bottom of the secondary keel 1. Limit bolts 4 are threadedly connected inside the two adjacent threaded holes 3. Limit grooves 5 are slidably fitted onto the bottom surface of the limit bolts 4. Adjustment plates 6 are provided outside the limit grooves 5. An adjustment mechanism is provided at the bottom of the secondary keel 1. During installation, the main screw 10 of the top expansion 13 is first connected. The main screw 10 is connected to the flange 12. The flange 12 is connected to the secondary screw 11. The secondary screw 11 is connected to the J-hanger 9. The top expansion 13 is then installed. At the top of the house, place the main keel 2 on the J hanger 9 and fix it with bolts. Install the secondary keel 1 at the bottom of the main keel 2. Fix the adjusting plate 6 at the bottom of the opposite end of the two secondary keels 1 with the limiting bolt 4. Do not tighten the limiting bolt 4 completely. After the secondary keel 1 of the overall ceiling structure is installed, observe whether there is any error that causes gaps between the secondary keels 1. If there are gaps, let the limiting groove 5 on the adjusting plate 6 slide the limiting bolt 4 to adjust the two secondary keels 1. Tighten the limiting bolt 4 to fix it, which improves the construction error tolerance of the prefabricated aluminum panel 14 ceiling.

[0031] Referring to the figure, the top of the J-hanger 9 is threaded with a secondary screw 11. By setting the secondary keel 1, the J-hanger 9 and the top flange 12 can be connected.

[0032] Referring to the figure, the top of the surface of the secondary screw 11 is threaded with a flange 12, which allows the height of the suspended ceiling to be adjusted.

[0033] Referring to the figure, the top thread of flange 12 is connected to main screw 10, which connects flange 12 and top explosion 13.

[0034] Referring to the figure, the top of the main screw 10 is threaded with a top explosion 13. By setting the top explosion 13, the ceiling can be fixed to the top of the house.

[0035] Referring to the diagram, an aluminum plate 14 is bolted to the side opposite to the secondary keel 1 on one side. By setting the aluminum plate 14, the top of the suspended ceiling can be closed.

[0036] Referring to the diagram, the length of the suspended ceiling is set to no more than 1.5 meters. If it exceeds this length, additional reinforcement structures are required.

[0037] Brief description of usage: When installing a suspended ceiling, first lay out the lines to position the overall structure of the ceiling. Connect the main threaded rod 10 of the ceiling expansion 13, connect the main threaded rod 10 to the flange 12, connect the flange 12 to the secondary threaded rod 11, and connect the secondary threaded rod 11 to the J-hanger 9. Install the ceiling expansion 13 on the top of the room. Place the main keel 2 on the J-hanger 9 and fix it with bolts. Install the secondary keel 1 at the bottom of the main keel 2. Fix the adjusting plate 6 at the bottom of the opposite ends of the two secondary keels 1 with the limit bolts 4. Do not tighten the limit bolts 4 completely. After the secondary keel 1 of the overall suspended ceiling structure is installed, observe whether there are any defects. The error caused by the current problem resulted in a gap between the secondary keels 1. When there is a gap, the limiting groove 5 on the adjusting plate 6 allows the limiting bolt 4 to slide, thereby adjusting the two secondary keels 1 and tightening the limiting bolt 4 to fix them. This improves the construction tolerance of the prefabricated aluminum panel 14 ceiling. The flexible displacement of the adjusting groove compensates for the installation error of the secondary keel 1, which not only avoids the rework and cutting caused by dimensional deviation in the traditional solution, but also maintains the universality of standardized components. This mechanical adjustment mechanism improves the on-site installation efficiency while ensuring the structural strength, and effectively solves the common problem of tolerance accumulation in prefabricated buildings.

[0038] Example 2:

[0039] Referring to the figure, a large-area prefabricated aluminum panel ceiling structure includes an adjustment structure comprising a slider 7, which is welded to the left side of the top of the secondary keel 1. A sliding groove 8 is slidably connected to the surface of the slider 7, and a main keel 2 is installed outside the sliding groove 8. A J-shaped hanger 9 is fitted onto the surface of the main keel 2. After the main keel 2 is installed, the slider 7 on the secondary keel 1 is inserted into the sliding groove 8 of the main keel 2, and the position of the secondary keel 1 is adjusted by sliding. After the entire secondary keel 1 is set up, the spacing between the secondary keels 1 is observed to see if the difference is too large. If there is a significant difference, the secondary keel 1 is slidably adjusted. After adjustment, it is bolted and fixed. This significantly improves the construction adaptability of the prefabricated aluminum panel ceiling 14 and simplifies the on-site leveling process. Workers only need to adjust the level of the main keel 2, and the secondary keel 1 can be positioned by sliding self-adaptation.

[0040] Brief description of the usage process: After the main keel 2 is installed, the slider 7 on the secondary keel 1 is inserted into the sliding groove 8 of the main keel 2. The position of the secondary keel 1 is adjusted by sliding. After the entire secondary keel 1 is set up, observe whether the gap between the secondary keels 1 is too large. If there is a large gap, slide the secondary keel 1 to adjust. After adjustment, bolt it in place. This greatly improves the construction adaptability of the prefabricated aluminum panel 14 ceiling and simplifies the on-site leveling process. After the worker adjusts the level of the main keel 2, the secondary keel 1 can be positioned by sliding and self-adapting. This significantly reduces the dependence on construction accuracy and is especially suitable for the efficient installation of complex shapes such as large spans.
