Description

Technical Field

[0001] The utility model belongs to the technical field of ceiling suspension, and specifically relates to a ceiling suspension anchoring device for BIM detailed design. Background Art

[0002] In large public building projects such as stations, the installation and maintenance of ceiling suspensions are important links in architectural design and construction. These buildings usually require the ceiling system to be not only beautiful and durable, but also highly safe and stable to cope with a large number of people and complex usage environments. However, traditional ceiling suspension anchoring devices often face some technical challenges in practical applications, especially in terms of the connection stability between the fixing bolts and the concrete under long-term use and complex working conditions.

[0003] With the continuous development of Building Information Modeling (BIM) technology, its application in architectural engineering design, construction, and management is becoming increasingly widespread. By creating a three-dimensional digital model, BIM technology can achieve refined management of the entire life cycle of a construction project, significantly improving the efficiency and quality of design, construction, and operation and maintenance.

[0004] In the design of ceiling suspension anchoring devices, BIM technology can play an important role. Through the BIM model, designers can accurately simulate the installation process of the ceiling, optimize the structural design of the anchoring device, improve construction accuracy and installation efficiency. At the same time, BIM technology can also assist in construction simulation and collision detection, discover and solve potential problems in advance, and ensure the stability and safety of the ceiling system.

[0005] Traditional anchoring devices mainly achieve fixation through the threaded fit of nuts and bolts. However, under long-term vibration, temperature changes, or the action of gravity, the nuts are prone to loosening, resulting in a weakened connection force between the ceiling and the concrete, and thus posing a safety hazard.

[0006] Therefore, in view of the above problems, a ceiling suspension anchoring device for BIM detailed design is proposed. Content of the Utility Model

[0007] In order to make up for the deficiencies of the prior art and solve the problem that traditional anchoring devices mainly achieve fixation through the threaded fit of nuts and bolts, but under long-term vibration, temperature changes, or the action of gravity, the nuts are prone to loosening, resulting in a weakened connection force between the ceiling and the concrete, and thus posing a safety hazard, a ceiling suspension anchoring device for BIM detailed design is proposed.

[0008] The technical solution adopted by the present utility model to solve its technical problems is as follows: A ceiling anchoring device for BIM detailed design of the present utility model includes an expansion sleeve, a fixing bolt, a gasket and a nut. The fixing bolt is installed on the inner wall of the expansion sleeve. The outer wall of the fixing bolt is sleeved with a gasket and a nut. The nut is threadedly connected with the fixing bolt. The gasket is slidably connected with the fixing bolt. An auxiliary mechanism is arranged on one side of the nut;

[0009] The auxiliary mechanism includes a second handle, a first fixing rod, a through hole, a first clamping groove, a second clamping groove and a movable groove. A movable groove is opened on one side of the nut. The first fixing rod is slidably installed on the inner wall of the movable groove. The end of the first fixing rod away from the expansion sleeve is fixedly installed with a second handle. The second handle is embedded in the inner wall of the first clamping groove and / or the second clamping groove. The first clamping groove and the first handle are opened on one side of the movable groove. The end of the second handle close to the expansion sleeve passes through the inner wall of the through hole. The through hole is opened on the side wall of the gasket. A telescopic mechanism is arranged at the end of the first fixing rod close to the expansion sleeve. A pushing mechanism is arranged on one side of the second handle; The stability of the connection between the fixing bolt and the concrete is improved, and the safety is improved at the same time.

[0010] Preferably, the telescopic mechanism includes a second fixing rod installed at the end of the first fixing rod. The second fixing rod is slidably installed on the inner wall of the storage groove. The storage groove is opened at the end of the first fixing rod. A control mechanism is arranged at the end of the second fixing rod close to the first fixing rod; When the first fixing rod passes through the through hole and abuts against the concrete, it can always abut against the concrete stably.

[0011] Preferably, the control mechanism includes a threaded rod arranged on the inner wall of the first fixing rod. The threaded rod passes through the first fixing rod and the second handle and is fixedly installed with a first handle. The threaded rod is threadedly connected with the inner wall of the first fixing rod; The friction between the second fixing rod and the concrete is increased, and the reliability of the auxiliary mechanism is further improved.

[0012] Preferably, the pushing mechanism includes an arc-shaped baffle arranged on one side of the second handle. The arc-shaped baffle is slidably embedded in the inner wall of the arc-shaped groove. The arc-shaped groove is opened on one side of the movable groove.

[0013] Preferably, the length from the end of the first fixing rod close to the expansion sleeve to the side of the second clamping groove close to the expansion sleeve is equal to the length from the side of the second clamping groove close to the expansion sleeve to the side of the nut close to the expansion sleeve; When the second handle is embedded in the inner wall of the second clamping groove, the end of the first fixing rod is flush with the nut, which will not affect the installation of the nut.

[0014] Preferably, the minimum length from the side of the first card slot close to the expansion sleeve to the side of the gasket close to the expansion sleeve is equal to the length between the two ends of the first fixing rod; when the second handle is inserted into the inner wall of the first card slot, the first fixing rod can pass through the through hole, so that the second fixing rod abuts against the concrete, thereby increasing the fulcrum between the nut and the concrete and playing a role in fixing the nut.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The following gives specific embodiments.

[0027] Please refer to Figures 1-4 , the present invention provides a ceiling anchoring device for BIM detailed design, including an expansion sleeve 1, a fixing bolt 2, a gasket 3 and a nut 4. The fixing bolt 2 is installed on the inner wall of the expansion sleeve 1, and the outer wall of the fixing bolt 2 is sleeved with the gasket 3 and the nut 4. The nut 4 is threadedly connected to the fixing bolt 2, and the gasket 3 is slidably connected to the fixing bolt 2. An auxiliary mechanism is provided on one side of the nut 4;

[0028] The auxiliary mechanism includes a second handle 11, a first fixing rod 8, a through hole 5, a first card slot 15, a second card slot 16 and a movable slot 17. A movable slot 17 is opened on one side of the nut 4, and the first fixing rod 8 is slidably installed on the inner wall of the movable slot 17. One end of the first fixing rod 8 away from the expansion sleeve 1 is fixedly installed with the second handle 11. The second handle 11 is embedded in the inner wall of the first card slot 15 and / or the second card slot 16. The first card slot 15 and the first handle 6 are opened on one side of the movable slot 17. One end of the second handle 11 close to the expansion sleeve 1 passes through the inner wall of the through hole 5. The through hole 5 is opened on the side wall of the gasket 3. A telescopic mechanism is provided at one end of the first fixing rod 8 close to the expansion sleeve 1, and a pushing mechanism is provided on one side of the second handle 11.

[0029] After the fixing bolt 2 is installed in the concrete, the second handle 11 can be rotated, so that the second handle 11 disengages from the second card slot 16 and is embedded in the inner wall of the first card slot 15, thereby driving the first fixing rod 8 to pass through the through hole 5 and abut against the concrete, so as to be able to assist in fixing the nut 4, avoiding the problem that the nut 4 is prone to loosen after long-term use, resulting in the loosening of the connection between the ceiling and the concrete and generating potential safety hazards, improving the stability of the connection between the fixing bolt 2 and the concrete, and improving the safety at the same time.

[0030] The telescopic mechanism includes a second fixed rod 9 installed at the end of the first fixed rod 8. The second fixed rod 9 is slidably installed on the inner wall of the receiving groove 10. The receiving groove 10 is opened at the end of the first fixed rod 8. A control mechanism is provided at one end of the second fixed rod 9 close to the first fixed rod 8, which can always be in stable contact with the concrete when the first fixed rod 8 passes through the through hole 5 and abuts against the concrete, avoiding the problem that after the concrete is drilled, the surface is relatively rough, which easily causes the first fixed rod 8 to be not in close contact with the concrete and affects the stable connection of the auxiliary mechanism, and improving the reliability of the auxiliary mechanism.

[0031] The control mechanism includes a threaded rod 7 provided on the inner wall of the first fixed rod 8. The threaded rod 7 passes through the first fixed rod 8 and the second handle 11 and is fixedly installed with a first handle 6. The threaded rod 7 is threadedly connected to the inner wall of the first fixed rod 8. The threaded rod 7 is fixedly connected to the second fixed rod 9. After the second handle 11 is inserted into the inner wall of the first card slot 15, the first handle 6 can be rotated, so that the first handle 6 drives the threaded rod 7 to abut against the second fixed rod 9, making the second fixed rod 9 closely fit the concrete, thereby increasing the friction between the second fixed rod 9 and the concrete and further improving the reliability of the auxiliary mechanism.

[0032] The pushing mechanism includes an arc-shaped baffle 13 provided on one side of the second handle 11. The arc-shaped baffle 13 is slidably embedded in the inner wall of the arc-shaped groove 12. The arc-shaped groove 12 is opened on one side of the movable groove 17. The arc-shaped baffle 13 is connected to the arc-shaped groove 12 through a return spring 14. After the second handle 11 is inserted into the first card slot 15 or the second card slot 16, the arc-shaped baffle 13 will block the second handle 11, avoiding the problem that the second handle 11 disengages from the inner wall of the first card slot 15 or the second card slot 16, resulting in the failure of the auxiliary mechanism, and improving the reliability of the device.

[0033] The length from one end of the first fixed rod 8 close to the expansion sleeve 1 to one side of the second card slot 16 close to the expansion sleeve 1 is equal to the length from one side of the second card slot 16 close to the expansion sleeve 1 to one side of the nut 4 close to the expansion sleeve 1, so that when the second handle 11 is inserted into the inner wall of the second card slot 16, the end of the first fixed rod 8 is flush with the nut 4, which will not affect the installation of the nut 4, avoiding the problem that when installing the nut 4, the first fixed rod 8 extends out of the nut 4, resulting in a large tangential force on the first fixed rod 8 during installation, which easily causes the first fixed rod 8 to be damaged and affects the installation of the nut 4 at the same time.

[0034] The minimum length from one side of the first card slot 15 close to the expansion sleeve 1 to one side of the gasket 3 close to the expansion sleeve 1 is equal to the length between the two ends of the first fixing rod 8. When the second handle 11 is inserted into the inner wall of the first card slot 15, the first fixing rod 8 can pass through the through hole 5, enabling the second fixing rod 9 to abut against the concrete, thereby increasing the fulcrum between the nut 4 and the concrete, playing a role in fixing the nut 4, avoiding the problem that the nut 4 is prone to loosening after long-term use, and improving the stability of the device.

[0035] Working principle: During the installation of the ceiling in the station, first drill a hole in the concrete, then sink the expansion sleeve 1 and the fixing bolt 2 into the hole, and then rotate the nut 4 to make the nut 4 push the expansion sleeve 1 to deform and embed in the hole, thus realizing the installation. Then rotate the second handle 11 to make the second handle 11 disengage from the inner wall of the second card slot 16 and slide along the movable slot 17 to be inserted into the inner wall of the first card slot 15. During the sliding process along the movable slot 17, the second handle 11 will drive the first fixing rod 8 to extend from the nut 4 and embed into the inside of the through hole 5 and abut against the concrete. When the second handle 11 is inserted into the inner wall of the first card slot 15, rotate the first handle 6 to make the first handle 6 drive the threaded rod 7 to rotate. The rotation of the threaded rod 7 will move along the inner wall of the first fixing rod 8, and the movement of the threaded rod 7 will drive the second fixing rod 9 to move, making the second fixing rod 9 abut against the concrete more tightly until the first handle 6 cannot be rotated, thereby realizing the fixation of the nut 4. In addition, after the second handle 11 is inserted into the inner wall of the first card slot 15, since the second handle 11 no longer presses the arc-shaped baffle 13, at this time, under the action of the return spring 14, it will drive the arc-shaped baffle 13 to move on the inner wall of the arc-shaped groove 12, making the side wall of the arc-shaped baffle 13 always fit with the second handle 11 to block the second handle 11 and prevent the second handle 11 from disengaging from the inner wall of the first card slot 15.

[0036] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
