Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a digital modular building auxiliary device based on BIM technology. Background Technology

[0002] BIM technology is not merely as intuitive as a simple 3D CAD file; its components are actually quite complex within the application, providing users with extremely high operational flexibility. When creating a single component, each BIM component is treated as a unique element in the building's form. When these components are loaded into the project model, users can clearly see their relationships with other building elements, thus enabling more precise design and construction.

[0003] Prefabricated modular construction, as an emerging construction method, has attracted much attention in recent years due to its advantages such as convenient construction and fast project progress. However, the assembly process of prefabricated components often requires the use of multiple support rods for assistance, as well as manual angle measurement and simultaneous support on both sides of the component, making the operation quite cumbersome. To solve this problem, we propose a prefabricated building solution based on BIM technology. Through the precise simulation and optimization of BIM technology, the support process can be simplified, assembly efficiency can be improved, and strong support can be provided for the further development of prefabricated modular construction.

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0021] Example

[0022] like Figure 1-4 As shown, the vertically spliced ​​precast component 3 is installed on the horizontally spliced ​​precast component 2. A pair of bases 1 are installed on the horizontally spliced ​​precast component 2 and the vertically spliced ​​precast component through a pair of fixed support structures. The angle adjustment structure is installed on a pair of fixed support structures. The fixed support structure includes: two pairs of lifting negative pressure shaft tubes 4, two pairs of lifting slide rail groups 5, two pairs of lifting slider groups 6, two pairs of lifting buffer limit shaft groups 7, two pairs of lifting limit sleeve spring groups, and two pairs of vacuum suction cups.

[0023] Specifically, each of the bases 1 has two pairs of telescopic cylindrical slots, the two pairs of lifting slide rail assemblies 5 are respectively installed on the inner side of the two pairs of telescopic cylindrical slots, the two pairs of lifting slider assemblies 6 are respectively installed on the two pairs of lifting negative pressure shaft tubes 4, and the two pairs of lifting slider assemblies 6 are respectively movably inserted into the inner side of the two pairs of lifting slide rail assemblies 5, the two pairs of lifting buffer limit shaft assemblies 7 are respectively inserted into the two pairs of lifting slide rail assemblies 5, and the two pairs of lifting buffer limit shafts are respectively movably inserted into the two pairs of lifting slider assemblies 6, the two pairs of lifting limit sleeve spring assemblies are respectively sleeved on the two pairs of lifting buffer limit shaft assemblies 7, and the two pairs of vacuum suction cups are respectively installed on the two pairs of lifting negative pressure shaft tubes 4;

[0024] It should be noted that, as described above, the lifting limit spring assembly on the lifting buffer limit shaft inside the lifting slide group 5 provides elastic pushing, which drives the lifting slider group 6 on it. The lifting slider group 6 then drives the lifting negative pressure shaft tube 4 on it to move up and down stably, thereby achieving the extension and retraction adjustment according to different wall shapes and uneven road surfaces. This allows the lifting negative pressure shaft tube 4 to move stably along the base 1, changing the extension and retraction length and effect of the pair of lifting negative pressure shaft tubes 4. Through the operation of the vacuum suction cups on the two pairs of lifting negative pressure shaft tubes 4, a pair of bases 1 are negatively adsorbed onto the vertical splicing precast component 3 and the horizontal splicing precast component 2. The support effect and angle are adjusted through the angle adjustment structure.

[0025] like Figure 1-4 As shown, the angle adjustment structure includes: a pair of concave horizontal telescopic blocks 8, a pair of convex horizontal telescopic blocks 9, a pair of horizontal telescopic threaded rods 10, a pair of horizontal telescopic threaded tubes 11, a pair of horizontal drive motors 12, two pairs of toothed extrusion blocks 13, multiple extrusion magnets 14, multiple extrusion repulsion magnets 15, two pairs of toothed repulsion blocks 16, multiple extrusion metal rods 17, a pair of concave bearing blocks 18, a pair of T-shaped telescopic rods 19, a pair of telescopic discs, a telescopic limiting shaft tube 20, an extended helical gear set, an extended drive shaft, an extended drive handle, a pair of extended limiting bearings, a pair of extended threaded tubes, and an extended threaded rod;

[0026] Specifically, a pair of concave horizontal telescopic blocks 8 are respectively installed on a pair of bases 1; a pair of convex horizontal telescopic blocks 9 are respectively movably inserted into the inner side of a pair of concave horizontal telescopic blocks 8; a pair of horizontal telescopic threaded rods 10 are respectively inserted into a pair of concave horizontal telescopic blocks 8 via supports; a pair of horizontal telescopic threaded tubes 11 are respectively inserted into a pair of convex horizontal telescopic blocks 9, and a pair of horizontal telescopic threaded tubes 11 are respectively movably fitted onto a pair of horizontal telescopic threaded rods 10; the driving ends of a pair of horizontal drive motors 12 are respectively connected to a pair of horizontal telescopic threaded rods 10; a pair of toothed extrusion limiting grooves are respectively opened on a pair of concave horizontal telescopic blocks 8; two pairs of toothed extrusion blocks 13 are respectively movably inserted into the inner side of two pairs of toothed extrusion limiting grooves; multiple extrusion metal rods 17 are evenly inserted into two pairs of toothed extrusion limiting grooves; a pair of toothed insertion grooves are respectively opened on a pair of concave horizontal telescopic blocks 8; two pairs of toothed repulsion blocks 16 are respectively movably inserted into two... On the inner side of the toothed insertion slot, a plurality of extrusion magnets 14 are respectively installed on a pair of toothed extrusion blocks 13, a plurality of extrusion repulsion magnets 15 are respectively installed on two pairs of toothed repulsion blocks 16, a pair of concave bearing blocks 18 are respectively installed on a pair of convex horizontal telescopic blocks 9, a pair of T-shaped telescopic rods 19 are respectively inserted into a pair of concave bearing blocks 18, the telescopic limiting shaft tube 20 is fitted onto a pair of T-shaped telescopic rods 19, a pair of telescopic discs are respectively installed onto a pair of T-shaped telescopic rods 19, the extension threaded rod is installed on the inner side of the telescopic limiting shaft tube 20 through a pair of extension limiting supports, the extension drive shaft is inserted into the telescopic limiting shaft tube 20, the extension helical gear set is installed on the extension threaded rod and the extension drive shaft, the extension drive handle is installed on the extension drive shaft, a pair of extension threaded tubes are respectively inserted into a pair of T-shaped telescopic rods 19, and a pair of extension threaded tubes are movably fitted onto the extension threaded rod;

[0027] It should be noted that, as described above, the operation of a pair of horizontal drive motors 12 on a pair of concave horizontal telescopic blocks 8 drives the horizontal telescopic threaded rods 10 on the drive ends of the pair of horizontal drive motors 12 to operate. The horizontal telescopic threaded rods 10 drive the horizontal telescopic threaded tubes 11 on them to rotate stably. The horizontal telescopic threaded tubes 11 drive the convex horizontal telescopic blocks 9 on them, so that the convex horizontal telescopic blocks 9 can move horizontally and horizontally along the inner side of the concave horizontal telescopic blocks 8. By changing the position of the two pairs of toothed repulsion blocks 16 inside the toothed insertion slots, the magnetic poles facing each other between the crossed extrusion repulsion magnets 15 on the toothed repulsion blocks 16 and the crossed extrusion magnets 14 on a pair of toothed extrusion blocks 13 are adjusted. The cross extension and retraction of the toothed repulsion blocks 16 transfers the magnetism of the extrusion repulsion magnets 15 on the toothed repulsion blocks 16 to the extrusion magnets 14 on the toothed extrusion blocks 13 through the extrusion metal rods 17. The extrusion magnets 14 drive the horizontal telescopic threaded tubes 11 to rotate stably. The toothed extrusion blocks 13 on it cause a pair of toothed extrusion blocks 13 to extend and retract relative to each other, thereby extruding and retracting the convex horizontal telescopic block 9 horizontally. This causes the toothed extrusion blocks 13 to extend and retract horizontally stably along the inner side of the toothed extrusion limiting groove, thereby pressing and limiting the convex horizontal telescopic block 9 to a certain position and fixing it to the inner side of the concave horizontal telescopic block 8. The extension drive handle is operated, which drives the extension drive shaft to rotate, which drives the extension drive shaft to drive the extension helical gear set on it. The operation of the extension helical gear set drives the extension threaded rod on it to rotate, which drives the pair of extension threaded tubes on it to extend and retract relative to each other. The pair of extension threaded tubes drive the T-shaped telescopic rods 19 on them respectively, so that the pair of T-shaped telescopic rods 19 extend and retract horizontally stably along the inner side of the telescopic limiting shaft tube 20. The pair of T-shaped telescopic rods 19 provide extension and extrusion support for the pair of concave bearing blocks 18.

[0028] As a preferred option, a level is further provided on each of the bases 1.

[0029] As a preferred option, furthermore, a plurality of pulley sets are provided on a pair of the bases 1.

[0030] As a preferred embodiment, a pair of tension ropes are provided on each of the bases 1, and each pair of tension ropes is movably inserted into a plurality of pulley groups.

[0031] As a preferred option, furthermore, each of the two pairs of lifting negative pressure shaft tubes 4 is provided with a circular rubber ring.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
