Description

Technical Field

[0001] The invention relates to the technical field of dome ceiling connection, in particular to a ceiling connection device based on dome shape. Background Art

[0002] There are generally two interpretations of a dome: a suspended hemispherical space or area; the apex or top of a dome or dome-shaped surface; specifically refers to the height difference between the center of a round arch road and its edge. Modern buildings that require a dome structure are generally exhibition halls, libraries, and other buildings that require good lighting. Most domes in modern buildings are glass dome structures, which use curved glass fixed by steel frames to form a dome with good lighting effects. Since modern building domes use a large number of metal frames, in order to reduce the impact of metal frames on the interior aesthetics of art exhibition halls such as libraries, GRG shaped dome structures are used to adapt to the dome arc surface, making the dome ceiling more beautiful.

[0003] When the existing dome-shaped ceiling connection device is in use, the ceiling is connected to the steel frame transfer layer by rivets or bolts, resulting in poor overall adaptability, making it impossible to fine-tune the dome-shaped ceiling connection device according to on-site installation needs. Since the GRG shaped dome structure is a special arc-shaped prefabricated structure, after the top of the ceiling connection device is connected to the steel frame transfer layer, it is very easy to cause errors in the connection between the bottom of the ceiling connection device and the GRG shaped dome structure due to installation errors and other problems, thereby affecting the lifting firmness and splicing accuracy of the GRG shaped dome structure, and reducing the use effect of the dome-shaped ceiling connection device.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing dome-shaped ceiling connection devices on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

[0037] See also Figure 1-11The present invention provides a technical solution: a ceiling connection device based on dome shape, comprising a connection mechanism 1, the connection mechanism 1 comprising an arc top 11, a plurality of hanging plates 12 are fixedly connected to the outer surface of the arc top 11, three vertical angle irons 13 are arranged on the top of the arc top 11, three horizontal angle irons 14 are arranged above the three vertical angle irons 13, the three vertical angle irons 13 are connected to the three horizontal angle irons 14 by bolts, and two mounting holes 15 are provided on the front of each horizontal angle iron 14, and an adjustment mechanism 2 is arranged on the top of the arc top 11;

[0038] The adjustment mechanism 2 comprises a suspended ceiling adaptation unit 21 . The suspended ceiling adaptation unit 21 is located above the arc top 11 . The suspended ceiling adaptation unit 21 is used to adjust the position of the arc top 11 .

[0039] As a further limitation of the adjustment mechanism 2 of the present invention, the ceiling adaptation unit 21 includes a fixed plate 2101, the fixed plate 2101 is located on the left side of the vertical angle iron 13, the right side of the fixed plate 2101 is fixedly connected with an upper clamping plate 2102, a lower clamping plate 2103 is arranged on the right side of the fixed plate 2101, the upper surface of the lower clamping plate 2103 and the bottom surface of the upper clamping plate 2102 are fixedly connected with a plurality of conical blocks 2104, the right side of the fixed plate 2101 is fixedly connected with a fixing frame 2105, the internal rotation of the fixing frame 2105 is connected with an elliptical shaft 2106, and the outer surface of the elliptical shaft 2106 is fixedly connected with a fixing frame 2105.

By setting the ceiling adaptation unit 21, and using the mounting hole 15 to connect the vertical angle iron 13 and the horizontal angle iron 14 to the position where the dome building needs to be suspended to form a dome angle iron conversion layer, the adjustment mechanism 2 can be quickly connected with the dome angle iron rotation layer formed by the vertical angle iron 13 and the horizontal angle iron 14 without using rivets or bolts. At the same time, when the connection position between the adjustment mechanism 2 and the dome angle iron conversion layer needs to be fine-tuned according to the on-site installation, it can be quickly disassembled and installed on different installation points of the vertical angle iron 13 or the horizontal angle iron 14 at different node positions, which effectively increases the adaptability of the connection between the adjustment mechanism 2 and the dome angle iron conversion layer, so that the connection between the adjustment mechanism 2 and the dome angle iron conversion layer can be fine-tuned according to the splicing error of the GRG dome structure (the GRG dome structure is composed of multiple arc tops 11 spliced ​​together), ensuring the convenience of hoisting and splicing accuracy of the GRG dome structure;

[0040] The upper surface of the fixing plate 2101 is fixedly connected with two reinforcing ribs 2116, and the bottom surfaces of the two reinforcing ribs 2116 are fixedly connected with the upper surface of the upper clamping plate 2102. The reinforcing ribs 2116 can increase the connection firmness between the upper clamping plate 2102 and the fixing plate 2101, so that the upper clamping plate 2102 is not easily deformed due to force, and the pressure bearing strength of the upper clamping plate 2102 is improved;

[0041] The fixed plate 2101 is internally slidably connected to a limiting block 2117, the right side of the limiting block 2117 is fixedly connected to the left side of the lower clamping plate 2103, and the limiting block 2117 slides inside the fixed plate 2101, which can limit the position of the lower clamping plate 2103 without affecting the up and down movement of the lower clamping plate 2103, thereby preventing the lower clamping plate 2103 from deflecting;

[0042] The outer surface of the connecting column 2113 is fixedly connected to a limiting ring 2118, and the limiting ring 2118 is rotatably connected to the inside of the connecting seat 2112. The limiting ring 2118 can limit the position of the connecting column 2113 inside the connecting seat 2112 without affecting the rotation of the connecting column 2113, thereby increasing the stability of the connecting column 2113 during use.

[0043] The specific implementation method of this embodiment is as follows: firstly, the vertical angle iron 13 and the horizontal angle iron 14 are arranged and spliced ​​as required, and the vertical angle iron 13 and the horizontal angle iron 14 are connected to the position where the ceiling of the dome building needs to be suspended by using the installation hole 15 to form a dome angle iron conversion layer. When it is necessary to fine-tune the position between the adjustment mechanism 2 and the dome angle iron conversion layer to adapt to the splicing error of the GRG-shaped dome structure, firstly use the pull plate 2111 to pull the clamping plate 2110 to the right to separate from the fixing frame 2105. At this time, the sliding frame 2108 will slide to the right inside the telescopic cylinder 2107 and force the telescopic spring 2109 Stretch, and then turn the telescopic cylinder 2107 clockwise to rotate the elliptical shaft 2106 ninety degrees and disengage from the lower clamping plate 2103, so that the upper clamping plate 2102 and the lower clamping plate 2103 lose the clamping force on the vertical angle iron 13, so that the connection between the adjustment mechanism 2 and the dome angle iron conversion layer is quickly loosened, which is convenient for the staff to fine-tune its position, so that the connection position between the adjustment mechanism 2 and the dome angle iron conversion layer can be quickly disassembled and installed on different installation points of the vertical angle iron 13 or the horizontal angle iron 14 at different node positions, so that the adjustment mechanism 2 and the dome angle iron conversion layer can be quickly disassembled and installed on different installation points of the vertical angle iron 13 or the horizontal angle iron 14 at different node positions. The connection between them can be fine-tuned according to the splicing error of the GRG dome structure to ensure the convenience of hoisting and the splicing accuracy of the GRG dome structure. When the upper clamping plate 2102 and the lower clamping plate 2103 are moved to the position after fine-tuning and need to be fixed, it is only necessary to turn the clamping plate 2110 counterclockwise to drive the elliptical shaft 2106 to rotate, and use the special shape of the elliptical shaft 2106 to push the lower clamping plate 2103 upward with the assistance of the limit block 2117, and then cooperate with the conical block 2104 on the upper clamping plate 2102 and the lower clamping plate 2103 to clamp and fix it on the vertical angle iron 13 or the horizontal angle iron 14. The connection between the adjustment mechanism 2 and the dome angle iron conversion layer is completed, and the connection column 2113 is rotated inside the connecting seat 2112 to cooperate with the limiting ring 2118, so that the top of the ceiling rope 2115 can be rotated as needed. At the same time, the movable frame 2114 can also allow the top of the ceiling rope 2115 to change its angle, so that the ceiling rope 2115 can adapt to the position change between the adjustment mechanism 2 and the dome angle iron conversion layer, and it is not easy for the ceiling rope 2115 to have torsional stress, thereby reducing the influence of the torsional stress of the ceiling rope 2115 on the GRG shaped dome structure.

[0045] See also Figure 1-11 The present invention provides a technical solution: a ceiling connection device based on dome shape. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0046] As a further limitation of the adjustment mechanism 2 of the present invention, the adjustment mechanism 2 further includes a ceiling adjustment unit 22, the ceiling adjustment unit 22 is located above the arc top 11, and the ceiling adjustment unit 22 is used to adjust the height of the arc top 11;

[0047] The ceiling adjustment unit 22 includes an adjustment box 2201, which is located above the arc top 11. A clamping frame 2202 is fixedly connected to the upper surface of the adjustment box 2201, and a plurality of tooth plates 2203 are fixedly connected to the inner wall of the clamping frame 2202. A clamping plate 2204 is slidably connected to the inside of the clamping frame 2202. The outer surfaces of the plurality of tooth plates 2203 and the right side of the clamping plate 2204 are in contact with the outer surface of the ceiling rope 2115. A support frame 2205 is fixedly connected to the left side of the clamping frame 2202. An adjusting bolt 2206 is connected to the internal thread of the support frame 2205. The right end of the adjusting bolt 2206 passes through one side of the clamping frame 2202 and is rotatably connected to the inside of the clamping plate 2204. Two symmetrically distributed fastening plates 2207 are hinged inside the adjustment box 2201. The two fastening plates 2207 are A plurality of anti-skid grooves 2208 are provided on the upper part of the outer surface, and the outer surfaces of the plurality of anti-skid grooves 2208 are in contact with the outer surface of the ceiling rope 2115. Two compression springs 2209 are fixedly connected to the side faces of the two fastening plates 2207 that are away from each other, and the other ends of the four compression springs 2209 are fixedly connected to the opposite sides of the adjustment box 2201, respectively. By setting the ceiling adjustment unit 22, the length of the ceiling rope 2115 can be adjusted according to the arc surface of the arc top 11, so that the distance between the adjustment mechanism 2 and the dome angle iron conversion layer can be freely adjusted according to the different height positions of the arc top 11, so that the adjustment mechanism 2 can more perfectly adapt to the arc surface ceiling requirements of the arc top 11, further increasing the fine-tuning adaptation range of the on-site installation of the ceiling connection device based on the dome shape, making the hoisting of the GRG shape dome structure more convenient, fast and accurate;

[0048] The right end of the adjusting bolt 2206 is fixedly connected with an anti-slip ring 2210, and the anti-slip ring 2210 is rotatably connected to the inside of the clamping plate 2204. The anti-slip ring 2210 can limit the position of the adjusting bolt 2206 inside the clamping plate 2204, so that the adjusting bolt 2206 will not be loosened from the clamping plate 2204, so that the adjusting bolt 2206 can smoothly drive the clamping plate 2204 to move left and right;

[0049] Two symmetrically distributed arc grooves 2211 are provided on the front and back of the adjustment box 2201, and sliding columns 2212 are fixedly connected to the front and back of the two fastening plates 2207. Each sliding column 2212 is slidably connected to the inside of the arc groove 2211, and the other end of each sliding column 2212 is fixedly connected to a lever block 2213. The sliding column 2212 slides inside the arc groove 2211 without affecting the smooth movement of the fastening plate 2207. At the same time, the lever block 2213 is used for the user to control the opening and closing of the fastening plate 2207 from the outside of the adjustment box 2201, thereby increasing the convenience of manual operation of the fastening plate 2207.

[0050] The specific implementation method of this embodiment is as follows: when it is necessary to fine-tune the length of the ceiling rope 2115 to adapt to the change in the horizontal height of the arc top 11, the ceiling rope 2115 located between the adjustment box 2201 and the clamping frame 2202 is pulled upward, and the friction force can be used to provide an upward pulling force for the fastening plate 2207, forcing the fastening plate 2207 to open outwards while the compression spring 2209 contracts, thereby completing the shortening of the ceiling rope 2115. After the ceiling rope 2115 is connected to the arc top 11, gravity will provide the ceiling rope 2115 with a tension force. The downward pulling force, at this time, the friction force between the ceiling rope 2115 and the fastening plate 2207, combined with the elastic force provided by the anti-slip groove 2208 and the compression spring 2209, can force the top ends of the two fastening plates 2207 to approach each other, thereby clamping the position of the ceiling rope 2115 after the fixed length is fine-tuned. Since the greater the downward pulling force, the greater the clamping force of the fastening plate 2207 on the ceiling rope 2115, the fixation of the ceiling rope 2115 after the length is fine-tuned is very stable. When the ceiling rope 2115 needs to be lengthened, only the pull block 2213 needs to be manually moved to force The sliding column 2212 slides inside the arc groove 2211 to move the top positions of the two fastening plates 2207 away from each other to loosen the limit on the ceiling rope 2115. When it is necessary to increase the length adjustment range of the ceiling rope 2115, it is only necessary to turn the adjusting bolt 2206 counterclockwise to make the adjusting bolt 2206 cooperate with the threaded connection relationship with the support frame 2205 and the limit of the adjusting bolt 2206 by the anti-slip ring 2210, so as to drive the clamping plate 2204 to move to the left to loosen the ceiling rope 2115. At this time, the clamping frame 2204 is moved upward. 202 position, increasing the stock of the ceiling rope 2115 between the adjustment box 2201 and the clamping frame 2202, can increase the length adjustment amount of the ceiling rope 2115, so that the distance between the arc top 11 and the dome angle iron conversion layer can be freely adjusted according to the different height positions of the arc top 11, so that the adjustment mechanism 2 can more perfectly adapt to the curved ceiling requirements of the arc top 11, further increasing the fine-tuning adaptation range of the on-site installation of the ceiling connection device based on the dome shape, making the lifting of the GRG shaped dome structure more convenient, fast and accurate.

By setting the fixing mechanism 3, it can cooperate with the ceiling adaptation unit 21 and the ceiling adjustment unit 22, so that the connection between the bottom of the adjustment mechanism 2 and the GRG shape dome structure can also be fine-tuned in direction and angle, preventing the ceiling rope 2115 in the adjustment mechanism 2 from generating torsional force due to the different angle direction structures on the GRG shape dome structure, thereby reducing the stress of the GRG shape dome structure after the ceiling is suspended, and further improving the ceiling stability and reliability of the GRG shape dome structure;

[0055] A reinforcement ring 312 is fixedly connected to the upper surface of the fixed tube 301, and the inner wall of the reinforcement ring 312 is fixedly connected to the outer surface of the ceiling rope 2115. The reinforcement ring 312 can increase the connection firmness between the fixed tube 301 and the ceiling rope 2115, making it difficult for the ceiling rope 2115 and the fixed tube 301 to loosen, thereby greatly improving the connection tightness between the fixed tube 301 and the ceiling rope 2115.

[0056] The specific implementation method of this embodiment is as follows: the positioning plate 307 can be used to insert the positioning column 309 into the reserved hole in the hanging plate 12 on the arc top 11, and then the positioning column 309 is inserted into the anti-drop plate 308. Due to the special shape of the clamping block 310, the return spring 311 can be forced to contract, allowing the clamping block 310 to enter the positioning column 309. When the clamping block 310 passes over the anti-drop plate 308, the return spring 311 will push the clamping block 310 to move upward and be located outside the positioning column 309 again. At this time, the positioning column 309 cooperates with the clamping block 310 to limit the hanging plate 12 on the arc top 11 between the positioning plate 307 and the anti-drop plate 308, so that the connection between the adjustment mechanism 2 and the arc top 11 also does not require the use of rivets or bolts. Therefore, when it is necessary to fine-tune the position between the ceiling rope 2115 and the arc top 11, it is only necessary to press the clamping block 310 to make it enter the positioning column 309 When the anti-slip plate 308 is detached from the hanging plate 12, the connection point between the adjustment mechanism 2 and the arc top 11 can be quickly removed, so that it can be fine-tuned to other positions of the arc top 11 and connected to the plate 12 according to on-site needs. Moreover, by rotating the fixed column 304 inside the fixed tube 301 and hingedly connecting the fixed column 304 with the movable seat 306, the positioning plate 307, the positioning column 309 and the anti-slip plate 308 can be fine-tuned in the horizontal direction and angle, so that the bottom of the ceiling rope 2115 can also better adapt to the arc shape of the arc top 11 and the lifting needs at different positions, and it is not easy for torsional stress to appear at the bottom end of the ceiling rope 2115, further improving the stability and reliability of the ceiling of the GRG shaped dome structure. The elastic force provided by the limit spring 302 cooperates with the meshing of the upper toothed disc 303 and the lower toothed disc 305, which can limit the position of the fixed column 304 after fine-tuning without affecting the rotation adjustment of the fixed column 304 too much.
