Description

Technical Field

[0001] The invention relates to the technical field of ceiling decoration, and in particular to an assembled installation structure for indoor large-area aluminum plate ceiling. Background Art

[0002] In interior decoration, most home ceiling designs and structures use aluminum plate ceiling decoration. The existing decoration method usually uses the light emitted by a laser level as a reference and performs the following operations: calculate the installation position of the hanger according to the indoor space, and drill a hole at that position. Then, insert an expansion bolt into one end of the hanger, use a hammer or other tools to hammer one end of the expansion bolt into the hole, and then use a wrench to fix the expansion bolt to the ceiling. A support hanger is fixed to the other end of the hanger through two nuts. The support hanger is used to hang the main keel. In order to ensure that the support hanger is at the same height, the two nuts on a single hanger need to be repeatedly adjusted, and then the main keel and the secondary keel are connected by the hanging buckle sleeved on the secondary keel. The spacing between the secondary keels needs to be arranged according to the width of the aluminum plate. A ruler is needed in this process, and multiple adjustments are made to ensure that the aluminum plate can be installed smoothly.

[0003] During the construction process, technicians in the field found some drawbacks: 1. When hammering the boom into the pre-set installation hole, construction workers generally need to stand on a ladder. Hammering from bottom to top and the small standing area will make it difficult for construction workers to exert force, increasing the difficulty of construction; 2. When adjusting the height of the support hanger from the ground, the two nuts need to be adjusted multiple times, which is inefficient; 3. After the main and secondary purlins are fixed together by hanging buckles, the spacing between the secondary purlins is difficult to control accurately. For example, it is very easy to touch the secondary purlin when installing the aluminum plate, causing the secondary purlin to deviate from its original position, increasing the difficulty of subsequent construction.

[0004] According to statistics from industry insiders, there are many specifications of aluminum plates for interior decoration, such as 300X300MM, 300X450MM, 300X600MM, 400X600MM, 400X800MM, 600X600MM, etc., and 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, and 600MM.

The switching mechanism 11 switches the operating state of the first limiting mechanism 9 and the second limiting mechanism 10 according to the size of the aluminum plate.

[0019] The distance adjusting mechanism 4 includes a cylinder 401 installed at one end of the lower suspension rod 3 close to the upper suspension rod 2, and a serrated hole 402 is opened on the cylinder 401. The serrated hole 402 can be regarded as two parts, one part is a strip hole, and the other part is a straight hole in a vertical array on both sides of the strip hole. An L-plate 403 is installed at one end of the upper suspension rod 2 close to the lower suspension rod 3, and a first spring telescopic rod 404 is installed on the L-plate 403. A clamping plate 405 is fixed to the end of the first spring telescopic rod 404 away from the L-plate 403, and a connecting rod 406 is fixed to the clamping plate 405. The connecting rod 406 is located at the center of the serrated hole 402, and a slide plate 407 is fixed to the end away from the clamping plate 405.

[0020] The first limiting mechanism 9 includes a limiting cylinder 901 installed through the reference hole 5 and the first correction hole 6. The limiting cylinders 901 are connected by a first connecting plate 902. A first limiting groove 903 is provided on one side of the fixing 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.

[0021] The second limiting mechanism 10 includes a limiting column 1001 installed through the reference hole 5 and the second correction hole 7. The limiting column 1001 in the reference hole 5 passes through the limiting tube 901 in the reference hole 5. The limiting columns 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. The limiting column 1001 is longer than the limiting tube 901, and its outer diameter is smaller than the inner diameter of the limiting tube 901. The limiting column 1001 partially located on the second connecting plate 1002 passes through the first connecting plate 902, and the passing part is a gap connection. A second limiting groove 1003 is provided on one side of the fixing 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 connected. The diameter of the second limiting groove 1003 is equal to the diameter of the limiting column 1001.

[0022] Taking the reference hole 5 as the standard, since the least common multiple of 300mm and 400mm is 1200, the limiting cylinder 901 on the first connecting plate 902 and the limiting column 1001 on the second connecting plate 1002 will be in the same position every 1200mm. In this state, the positional relationship between the limiting cylinder 901 and the limiting column 1001 is the same as that in the reference hole 5, that is, the limiting column 1001 penetrates the limiting cylinder 901.

[0023] The switching mechanism 11 includes a support plate 1101 relatively installed at the bottom of the main keel 1, and a rotating shaft 1102 is installed through the support plate 1101, and a strip rod 1103 is installed on the rotating shaft 1102. The strip rod 1103 is respectively provided with a first slide groove 1104 and a second slide groove 1105. The first connecting plate 902 and the second connecting plate 1002 are respectively provided with a first slide bar 1107 and a second slide bar 1108 at the bottom. The first slide bar 1107 and the second slide bar 1108 are respectively located in the first slide groove 1104 and the second slide groove 1105 on the corresponding sides. The switching mechanism 11 also includes a limiter 1106 installed on the main keel 1, and the limiter 1106 is connected to the rotating shaft 1102, and applies a transmission force to the rotating shaft 1102 and limits the rotation angle of the rotating shaft 1102.

[0024] The limiting member 1106 includes a worm wheel 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, and both ends of the rotating rod 11063 are provided with a spiral pattern 11064, which meshes with the worm wheel 11061 on the corresponding side.

[0025] A guiding mechanism 12 is installed on the fixed seat 8. After the switching mechanism 11 completes the adjustment of the first limiting mechanism 9 and the second limiting mechanism 10, the fixed seat 8 is stopped at a specific position by relying on the limiting cylinder 901 of the first limiting mechanism 9 and the limiting column 1001 of the second limiting mechanism 10. The guiding mechanism 12 includes a fixing plate 1201 installed on the side of the fixed seat 8 close to the reference hole 5, and a second spring telescopic rod 1202 is installed on the fixing plate 1201. An arc plate 1203 is installed on the end of the second spring telescopic rod 1202 away from the fixing plate 1201, and both sides of the arc plate 1203 are inclined surfaces.

[0026] The middle portion of the rotating rod 11063 is hexagonal, and when the rotating rod 11063 is rotated, it is easier to exert force compared to a cylinder, and the rotating rod 11063 can also be rotated with the help of a wrench.

[0027] The working principle is as follows: the construction worker replaces the drill bit of the electric drill with an inner hexagon socket, which is a prior art and an essential tool at the construction site. The side of the upper suspension rod 2 connected with the expansion bolt 203 is docked with the pre-set installation hole, and the hexagonal rod 305 connected to the lower suspension rod 3 is docked with the inner hexagon socket. Then the electric drill is moved upward, and the electric drill drives the hexagonal tube 201 to move upward through the hexagonal rod 305, the lower suspension rod 3, the sleeve, and the upper suspension rod 2. Since the expansion bolt 203 is restricted by the pre-set installation hole and cannot move, the hexagonal tube 201 compresses the first telescopic rod 202, and finally the top of the hexagonal cover is fixed with the fixed The hexagonal groove 205 of the fixed ring 204 is engaged, and the electric drill is turned on at this time. The electric drill drives the entire expansion bolt 203 to rotate, and finally the entire expansion bolt 203 enters the installation hole. At this time, the expansion bolt 203 is in close contact with the inner wall of the installation hole, and the friction is large. The construction worker moves the electric drill downward by a small amplitude, and the hexagonal cylinder 201 moves downward with the electric drill, disengaging from the hexagonal groove 205, but still surrounds the hexagonal nut of the expansion bolt 203. At this time, the electric drill is turned on again, and the electric drill drives the hexagonal nut part of the expansion bolt 203 to rotate, so that the upper suspension rod 2 and the connecting part are fixed by the expansion bolt 203; like Figure 4 As shown, the support hanger 304 and the main keel 1 on the support hanger 304 are installed. The operation is: fit the U-shaped part of the support hanger 304 with the top of the limiting ring 301, and then rotate the limiting nut 303 to limit the support hanger 304 by clamping the limiting nut 303 and the limiting ring 301.

[0028] When the height of the main keel 1 from the ground needs to be adjusted, the construction worker manually presses the slide plate 407, and the slide plate 407 presses the card plate 405 into the inside of the cylinder 401 through the connecting rod 406. At this time, the card plate 405 compresses the first spring telescopic rod 404, and the contact card plate 405 is engaged with the toothed hole 402 on the lower suspension rod 3. At this time, the worker's fingers continue to press the slide plate 407, and the palm and other fingers can control the lower suspension rod 3 to move freely, thereby changing the distance between the lower suspension rod 3 and the upper suspension rod 2 through the movement of the lower suspension rod 3, and then changing the distance between the main keel 1 and the ground through the lower suspension rod 3 and the support hanger 304. After adjusting to the appropriate distance, the worker releases the hand pressing the slide plate 407, and the first spring telescopic rod 404 is reset, driving the card plate 405 to re-engage with the toothed hole 402 to complete the limit.

[0029] It should be noted that before installing the upper suspension rod 2 and its connecting parts, the number of teeth in the toothed hole 402 can be used to control the length of each upper suspension rod 2 and the corresponding lower suspension rod 3 after they are matched. After all are installed, even if adjustments are required, only minor operations need to be performed on a small part.

[0030] 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 300mm or 600mm, the construction worker rotates the rotating rod 11063, and the spiral patterns 11064 at both ends of the rotating rod 11063 synchronously drive the worm wheels 11061 on both sides to rotate synchronously and in the same direction. The worm wheels 11061 drive the strip rod 1103 to rotate through the rotating shaft 1102. Under the guidance of the first slide groove 1104 and the second slide groove 1105 on the strip rod 1103, the first connecting plate 902 and the second connecting plate 1002 are driven away from each other through the first slide rod 1107 and the second slide rod 1108. In this state, the first connecting plate 902 moves toward the direction close to the main keel 1, and the second The 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 correction hole 6 is greater than the depth of the limiting column 1001 penetrating the second correction hole 7, and the limiting cylinder 901 and the fixed seat 8 on the side close to the first correction hole 6 are almost in contact with each other. At this time, the construction worker slides the hanging plate buckle 102. During the sliding process of the hanging plate buckle 102 in the first through hole 101 on the main keel 1, each time the fixed seat 8 fixed with the hanging plate buckle 102 passes through the limiting cylinder 901, the curved plate 1203 moves downward under the guidance of the inclined surfaces on both sides of the curved plate 1203, compressing the second spring telescopic rod 1202. When the curved plate 1203 coincides with the curved surface at the bottom of the limiting cylinder 901, The second spring telescopic rod 1202 is reset to make the arc plate 1203 fit with the bottom of the limiting cylinder 901. At this time, the construction worker will feel obvious resistance when continuing to exert force. Since the spacing between the limiting cylinders 901 is 300mm, the construction worker can accurately control the spacing between the hanging plate buckles 102 according to the size of the aluminum plate. For example, if the width of the aluminum plate is 300mm, the construction worker slides the hanging plate buckles 102 in turn to make them correspond to the positions of the limiting cylinders 901 one by one. Under the action of the guiding mechanism 12, the spacing between the hanging plate buckles 102 will be automatically pre-positioned every 300mm, thereby realizing the distance control between the hanging plate buckles 102. If the width of the aluminum plate is 600mm, the spacing at the position of the reference hole 5 is used as the limit. The first connecting plate 902 is used as the reference, and a hanging plate buckle 102 is arranged at the position of the next limiting cylinder 901 for every other limiting cylinder 901. When all the hanging plate buckles 102 are arranged, the rotating rod 11063 is continued to be rotated in the direction of the initial rotation of the rotating rod 11063. At this time, the first connecting plate 902 continues to drive the limiting cylinder 901 to move away from the second connecting plate 1002, and one end of the limiting cylinder 901 is engaged with the first limiting groove 903 on the fixing seat 8 to complete the fixing of the fixing seat 8. Then, the first secondary keel 103 is installed on the hanging plate buckle 102 corresponding to the limiting cylinder 901 at the position of the reference hole 5, and the secondary keels 103 are installed on the subsequent hanging plate buckles 102 in sequence according to the size of the aluminum plate; If the width of the aluminum plate is 400mm, rotate the rotating rod 11063 in the opposite direction. Unlike the aluminum plate with an installation width of 300 / 600mm, 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 toward the main keel 1.
