Description

Technical Field

[0001] The present invention relates to the technical field of decorative ceilings, and particularly to an assembled installation structure for large-area aluminum plate ceilings indoors. Background Art

[0002] In interior decoration, most families adopt aluminum plate ceilings for the design and construction of the ceiling. The existing decoration method usually uses the light emitted by a laser level as a reference and performs the following operations: Calculate the installation positions of the suspenders according to the indoor space, drill holes at these positions, then sleeve an expansion bolt at one end of the suspender, use tools such as a hammer to hammer one end of the expansion bolt into the hole, and then fix the expansion bolt to the ceiling through a wrench. At the other end of the suspender, a support hanger is fixed by two nuts. The support hanger is used for hoisting the main keel. To ensure that the support hangers are at the same height, the two nuts on a single suspender need to be repeatedly adjusted in position. Then, the main keel and the secondary keel are connected through the hanging pieces buckled on the secondary keel. The spacing between the secondary keels needs to be arranged according to the width of the aluminum plate. During this process, a ruler is required and multiple adjustments are needed to ensure the smooth installation of the aluminum plate.

[0003] During the construction process, those skilled in the art found some drawbacks:

[0004] 1. During the process of hammering the suspender into the pre-set installation hole, construction workers generally need to stand on a ladder. Due to reasons such as hammering from bottom to top and a small standing area, it is difficult for construction workers to exert force, increasing the construction difficulty.

[0005] 2. When adjusting the height of the support hanger from the ground, the two nuts need to be adjusted multiple times, resulting in low efficiency.

[0006] 3. After fixing the main and secondary keels together through the hanging pieces, it is very difficult to precisely control the spacing between the secondary keels. For example, when installing the aluminum plate, it is very easy to touch the secondary keel, causing the secondary keel to deviate from its original position, increasing the difficulty of subsequent construction.

[0007] According to the statistics of industry insiders, there are various specifications for aluminum plates used in interior decoration, such as 300X300MM, 300X450MM, 300X600MM, 400X600MM, 400X800MM, 600X600MM, etc. For the sake of hoisting stability, the spacing between the secondary keels is equal to the short side of the aluminum plate, that is, the spacing between the secondary keels is generally 300MM, 400MM, 600MM. Based on this, this solution proposes a ceiling installation structure suitable for most interior decorations to solve the above problems. Summary of the Invention

Embodiment

[0047] Please refer to Figures 1 - 15 , the present invention provides a technical solution: an assembled installation structure for large-area aluminum plate ceiling indoors, including a main keel 1. A first through hole 101 is opened at the bottom end of the main keel 1. A hanger buckle 102 is slidably installed in the first through hole 101. There are multiple hanger buckles 102, and a secondary keel 103 is clamped on each hanger buckle 102. The secondary keel 103 is used to support the aluminum plate, and further includes:

[0048] An upper suspension rod 2. A hexagonal cylinder 201 is fixed at the top end of the upper suspension rod 2. A first telescopic rod 202 is installed in the hexagonal cylinder 201. One end of the first telescopic rod 202 away from the upper suspension rod 2 is fixed with an expansion bolt 203. A fixing ring 204 is sleeved on the expansion bolt 203. The fixing ring 204 is directly fixed on the expansion sleeve of the expansion bolt 203. A hexagonal groove 205 is opened at the bottom of the fixing ring 204. The inner diameter of the inner wall of the hexagonal groove 205 is larger than the outer diameter of the hexagonal cylinder 201;

[0049] When one end of the hexagonal cylinder 201 is located inside the hexagonal groove 205, the hexagonal cylinder 201 restricts both the hexagonal nut and the expansion sleeve of the expansion bolt 203 at the same time. If the hexagonal cylinder 201 rotates, the entire expansion bolt 203 will rotate.

[0050] The lower suspension rod 3 has a limiting ring 301 sleeved thereon. A thread 302 is provided on the lower suspension rod 3. The thread 302 is located above the limiting ring 301. A limiting nut 303 is sleeved on the thread 302. A support hanging member 304 is provided between the limiting nut 303 and the limiting ring 301. The support hanging member 304 fits with the lower suspension rod 3, and the contact part with the lower suspension rod 3 is U-shaped. The limiting nut 303, the thread 302, and the limiting ring 301 cooperate to fix the position of the support hanging member 304. The support hanging member 304 is used for hoisting the main keel 1. One end of the lower suspension rod 3 far from the upper suspension rod 2 is fixed with a hexagonal rod 305;

[0051] The distance adjusting mechanism 4 is installed on the lower suspension rod 3 and is connected to the upper suspension rod 2. The distance adjusting mechanism 4 is used to adjust the distance between the lower suspension rod 3 and the upper suspension rod 2, so as to change the distance between the main keel 1 and the floor through the support hanging member 304 on the lower suspension rod 3;

[0052] The reference hole 5 is provided on the main keel 1;

[0053] The first calibration hole 6, as Figure 15 shown, the first calibration hole 6 is provided on the main keel 1 and there are several. The distance between the first calibration holes 6 is 300 mm. The distance between the first calibration hole 6 closest to the reference hole 5 and the reference hole 5 is 300 mm;

The distance between the second calibration holes 7 is 400 mm. The distance between the first calibration hole 6 closest to the reference hole 5 and the reference hole 5 is 400 mm;

[0055] There are several fixing seats 8, which are installed on the hanging piece buckle 102 and are located inside the main keel 1;

[0056] The first limiting mechanism 9 is installed on the first calibration hole 6 and is connected to the reference hole 5. The first limiting mechanism 9 combines the reference hole 5 and the first calibration hole 6 to limit the positions of the fixing seats 8 with an interval distance of 300 mm and 600 mm;

[0057] The second limiting mechanism 10 is installed on the second calibration hole 7 and connected to the reference hole 5. The second limiting mechanism 10 combines the reference hole 5 and the second calibration hole 7 to limit the position of the fixed seat 8 with a spacing distance of 400 mm.

[0058] The switching mechanism 11 is installed on the main keel 1 and connected to the first limiting mechanism 9 and the second limiting mechanism 10. The switching mechanism 11 switches the operating states of the first limiting mechanism 9 and the second limiting mechanism 10 according to the size of the aluminum plate.

[0059] The distance adjustment mechanism 4 includes a cylinder 401 installed at one end of the lower suspension rod 3 close to the upper suspension rod 2. A toothed hole 402 is formed in the cylinder 401. The toothed groove 402 can be regarded as two parts. One part is a strip hole, and the other part is a linear hole vertically arranged on both sides of the strip hole. An L-shaped plate 403 is installed at one end of the upper suspension rod 2 close to the lower suspension rod 3. A first spring telescopic rod 404 is installed on the L-shaped plate 403. A clamping plate 405 is fixed at one end of the first spring telescopic rod 404 away from the L-shaped plate 403. A connecting rod 406 is fixed on the clamping plate 405. The connecting rod 406 is located at the center position of the toothed hole 402, and a sliding plate 407 is fixed at one end of the connecting rod 406 away from the clamping plate 405.

[0060] The first limiting mechanism 9 includes a limiting cylinder 901 installed through the reference hole 5 and the first calibration hole 6. The limiting cylinders 901 are connected by a first connecting plate 902. A first limiting groove 903 is formed on one side of the fixed seat 8 close to the first connecting plate 902. The diameter of the first limiting groove 903 is equal to the outer wall diameter of the limiting cylinder 901.

[0061] The second limiting mechanism 10 includes a limiting post 1001 installed through the reference hole 5 and the second calibration hole 7. The limiting post 1001 in the reference hole 5 penetrates through the limiting cylinder 901 in the reference hole 5. The limiting posts 1001 are connected by a second connecting plate 1002. The first connecting plate 902 is located between the second connecting plate 1002 and the main keel 1, and the length of the limiting post 1001 is greater than that of the limiting cylinder 901, the outer diameter is smaller than the inner diameter of the limiting cylinder 901, and a part of the limiting post 1001 located on the second connecting plate 1002 penetrates through the first connecting plate 902, and the penetrated part is in clearance connection. A second limiting groove 1003 is formed on one side of the fixed seat 8 close to the first connecting plate 902. The second limiting groove 1003 is coaxial with the first limiting groove 903 and the two are communicated. The diameter of the second limiting groove 1003 is equal to the diameter of the limiting post 1001.

[0062] Taking the reference hole 5 as the standard, since the least common multiple of 300 mm and 400 mm is 1200, every 1200 mm, the limiting cylinder 901 on the first connecting plate 902 and the limiting post 1001 on the second connecting plate 1002 will be in the same position. In this state, the positional relationship between the limiting cylinder 901 and the limiting post 1001 is the same as that inside the reference hole 5, that is, the limiting post 1001 penetrates through the limiting cylinder 901.

[0063] The switching mechanism 11 includes support plates 1101 oppositely installed at the bottom of the main keel 1. Rotating shafts 1102 are installed through the support plates 1101. Strip-shaped rods 1103 are installed on the rotating shafts 1102. First chutes 1104 and second chutes 1105 are respectively formed on the strip-shaped rods 1103. First sliding rods 1107 and second sliding rods 1108 are respectively arranged oppositely at the bottoms of the first connecting plate 902 and the second connecting plate 1002. The first sliding rods 1107 and the second sliding rods 1108 are respectively located in the first chutes 1104 and the second chutes 1105 on the corresponding sides. The switching mechanism 11 further includes a limiting member 1106 installed on the main keel 1. The limiting member 1106 is connected to the rotating shaft 1102, applies a driving force to the rotating shaft 1102 respectively, and limits the rotation angle of the rotating shaft 1102.

[0064] The limiting member 1106 includes a worm gear 11061 sleeved on the rotating shaft 1102 and a support seat 11062 installed on the support plate 1101. A rotating rod 11063 is installed through the support seat 11062. Threaded grooves 11064 are formed at both ends of the rotating rod 11063. The threaded grooves 11064 are engaged with the worm gears 11061 on the corresponding sides.

[0065] A guiding mechanism 12 is installed on the fixed seat 8. After the switching mechanism 11 finishes adjusting the first limiting mechanism 9 and the second limiting mechanism 10, relying on the limitation of the limiting cylinder 901 of the first limiting mechanism 9 and the limiting post 1001 of the second limiting mechanism 10, the fixed seat 8 pauses at a specific position. The guiding mechanism 12 includes a fixing plate 1201 installed on one side of the fixed seat 8 close to the reference hole 5. A second spring telescopic rod 1202 is installed on the fixing plate 1201. An arc-shaped plate 1203 is installed at one end of the second spring telescopic rod 1202 away from the fixing plate 1201. Both sides of the arc-shaped plate 1203 are inclined planes.

[0066] The middle part of the rotating rod 11063 is hexagonal. When rotating the rotating rod 11063, compared with a cylinder, it is easier to apply force, and a wrench can also be used to rotate the rotating rod 11063.

[0067] The working principle is as follows: The construction worker replaces the drill bit of the electric drill with an internal hexagon socket, which is an existing technology and an essential tool at the construction site. Connect the side of the upper suspension rod 2 with the expansion bolt 203 to the pre-set installation hole, and connect the hexagonal rod 305 of the lower suspension rod 3 to the internal hexagon socket. Then, move the electric drill upward. The electric drill drives the hexagonal cylinder 201 to move upward through the hexagonal rod 305, the lower suspension rod 3, the socket, and the upper suspension rod 2. Since the expansion bolt 203 is restricted by the pre-set installation hole and cannot move, the hexagonal cylinder 201 compresses the first telescopic rod 202. Finally, the top of the hexagonal cover engages with the hexagonal groove 205 of the fixed ring 204. At this time, turn on the electric drill, and the electric drill drives the entire expansion bolt 203 to rotate. Eventually, the entire expansion bolt 203 enters the internal part of the installation hole. At this time, the expansion bolt 203 is in close contact with the inner wall of the installation hole, and the frictional force is large. The construction worker moves the electric drill downward slightly, and the hexagonal cylinder 201 follows the electric drill downward and disengages from the hexagonal groove 205, but still surrounds the hexagonal nut of the expansion bolt 203. At this time, turn on the electric drill again, and the electric drill drives the hexagonal nut part of the expansion bolt 203 to rotate, so as to fix the upper suspension rod 2 and the connection part through the expansion bolt 203;

[0068] As Figure 4 shown in the figure, install the support hanger 304 and the main keel 1 on the support hanger 304. The operation is as follows: Fit the U-shaped part of the support hanger 304 to the top of the limit ring 301, and then rotate the limit nut 303. Through the clamping of the limit nut 303 and the limit ring 301, the support hanger 304 is limited.

[0069] When the height of the main keel 1 from the ground needs to be adjusted, the construction worker manually presses the sliding plate 407. The sliding plate 407 presses the clamping plate 405 into the cylinder 401 through the connecting rod 406. At this time, the clamping plate 405 compresses the first spring telescopic rod 404, and the engagement between the contact clamping plate 405 and the toothed hole 402 on the lower suspension rod 3 is released. At this time, the worker's finger continuously presses the sliding plate 407, and the palm and the remaining fingers can control the free movement of the lower suspension rod 3. Thus, through the movement of the lower suspension rod 3, the distance between the lower suspension rod 3 and the upper suspension rod 2 is changed. Furthermore, through the lower suspension rod 3 and the support hanger 304, the distance between the main keel 1 and the ground is changed. After adjusting to the appropriate distance, the worker releases the hand pressing the sliding plate 407, and the first spring telescopic rod 404 resets, driving the clamping plate 405 to engage with the toothed hole 402 again to complete the limit.

[0070] It should be noted that before installing the upper suspension rod 2 and its connection part, the length of each upper suspension rod 2 and the corresponding lower suspension rod 3 after cooperation can be controlled to be equal by the number of teeth of the toothed hole 402. After all the installations are completed, even if adjustment is needed, only a small part needs to be operated slightly.

[0071] After the main keel 1 is installed, the secondary keel 103 is installed according to the width of the aluminum plate. If the width of the aluminum plate is 300 mm or 600 mm, the construction worker rotates the rotating rod 11063. The spiral threads 11064 at both ends of the rotating rod 11063 drive the two side worm wheels 11061 to rotate synchronously and in the same direction. The worm wheel 11061 drives the strip-shaped rod 1103 to rotate through the rotating shaft 1102. Under the guidance of the first chute 1104 and the second chute 1105 on the strip-shaped rod 1103, the first connecting plate 902 and the second connecting plate 1002 are driven to move away from each other by the first sliding rod 1107 and the second sliding rod 1108. In this state, the first connecting plate 902 moves towards the direction close to the main keel 1, and the second connecting plate 1002 drives the limiting column 1001 to move away from the main keel 1, so that the depth of the limiting cylinder 901 penetrating the first calibration hole 6 is greater than the depth of the limiting column 1001 penetrating the second calibration hole 7. The surface where the limiting cylinder 901 is located on the side close to the first calibration hole 6 of the fixed seat 8 is almost in contact. At this time, the construction worker slides the hanging piece buckle 102. During the process of the hanging piece buckle 102 sliding in the first through hole 101 on the main keel 1, every time the fixed seat 8 fixed to the hanging piece buckle 102 passes by the limiting cylinder 901, under the guidance of the inclined surfaces on both sides of the arc-shaped plate 1203, the arc-shaped plate 1203 moves downward, compressing the second spring telescopic rod 1202. When the arc-shaped plate 1203 coincides with the arc surface at the bottom of the limiting cylinder 901, the second spring telescopic rod 1202 resets, so that the arc-shaped plate 1203 fits with the bottom of the limiting cylinder 901. At this time, when the construction worker continues to exert force, an obvious resistance will be felt. Since the distance between the limiting cylinders 901 is 300 mm, the construction worker can accurately control the distance between the hanging piece buckles 102 according to the size of the aluminum plate. For example, if the width of the aluminum plate is 300 mm, the construction worker slides the hanging piece buckles 102 in sequence to make them correspond to the positions of the limiting cylinders 901 one by one. Under the action of the guiding mechanism 12, the distance between the hanging piece buckles 102 will be automatically pre-positioned every 300 mm, so as to realize the distance control between the hanging piece buckles 102. If the width of the aluminum plate is 600 mm, taking the limiting cylinder 901 at the position of the reference hole 5 as the reference, a hanging piece buckle 102 is arranged at the position of every other limiting cylinder 901. After all the hanging piece buckles 102 are arranged, continue to rotate the rotating rod 11063 in the direction of rotating the rotating rod 11063 at the beginning. At this time, the first connecting plate 902 continues to drive the limiting cylinder 901 to move away from the second connecting plate 1002. One end of the limiting cylinder 901 is engaged into the first limiting groove 903 on the fixed seat 8, completing the fixation of the position of the fixed seat 8. Subsequently, install the first secondary keel 103 on the hanging piece buckle 102 corresponding to the limiting cylinder 901 at the position of the reference hole 5, and install the secondary keel 103 on the subsequent hanging piece buckles 102 in sequence according to the size of the aluminum plate;

[0072] If the width of the aluminum plate is 400 mm, then rotate the rotating rod 11063 in the reverse direction. Different from the aluminum plate with an installation width of 300 / 600 mm, in this state, the first connecting plate 902 moves away from the main keel 1, and the second connecting plate 1002 drives the limiting column 1001 to move towards the main keel 1. At this time, the depth of the limiting column 1001 penetrating the second calibration hole 7 is greater than the depth of the limiting cylinder 901 penetrating the first calibration hole 6, and the surface where the limiting column 1001 is located on the side close to the first calibration hole 6 of the fixed seat 8 is almost in contact. Just perform the same operation as above.

[0073] It should be noted that there are multiple main keels 1, secondary keels 103 and various connected components in this structure, and corresponding arrangements are made according to the actual size of the installation site and the specifications of the aluminum plate.

[0074] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0075] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
