Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a BIM-based prefabricated building structure and its method. Background Technology

[0002] BIM systems are a series of software for building information modeling. BIM-based prefabricated building structures utilize BIM technology to design, construct, and manage prefabricated building structures. Prefabricated building structures utilize modular components prefabricated in factories and then assembled into a complete building structure system on site. BIM-based prefabricated structures, on the other hand, use digital modeling technology to integrate and optimize the design, production, and construction processes of prefabricated building structures. Existing prefabricated structures are too simple during assembly, lack flexibility, and cannot be adjusted after assembly, resulting in low adaptability. Therefore, this invention researches and designs a BIM-based prefabricated building structure and its method. Summary of the Invention

[0027] S2: Adjust the position adjustment mechanism, height adjustment mechanism, first adjustment mechanism and second adjustment mechanism of each building assembly structure according to the first angle information, second angle information and position information of each building assembly structure, so that the construction surface of each assembly plate after assembly matches the target building model.

[0029] The BIM-based prefabricated building structure and method provided by this invention have the following beneficial effects:

[0030] 1. This invention uses a position adjustment mechanism to adjust the relative position of the assembly plate on the slide rail, and a height adjustment mechanism to adjust the height of the assembly plate. The first adjustment mechanism and the second adjustment mechanism respectively adjust the angle between the height adjustment mechanism and the position adjustment mechanism, and the angle between the assembly plate and the height adjustment mechanism. Together, they change the posture of the assembly plate relative to the slide rail. At the same time, based on the adjustment of the height adjustment mechanism, the first adjustment mechanism and the second adjustment mechanism work together to further adjust the height of the assembly plate, so that any construction surface can be built.

At the same time, a limit range is formed between different sliding blocks, which can control the adjustment range when fine-tuning is required after assembly, making it easier to adjust the height of the assembly plate.

[0044] like Figure 1-9 As shown, the present invention provides a BIM-based building assembly structure, mounted on a pair of slide rails 2, comprising:

[0045] Assembly plate 1, wherein multiple assembly plates 1 are disposed above the slide rail 2;

[0046] Multiple position adjustment mechanisms are respectively provided between the assembly plate 1 and the pair of slide rails 2 to adjust the position between two adjacent assembly plates 1;

[0047] Multiple height adjustment mechanisms are respectively provided between the assembly plate 1 and the position adjustment mechanism to adjust the height position of the assembly plate 1;

[0048] The first adjustment mechanism and the second adjustment mechanism are respectively disposed between the position adjustment mechanism and the height adjustment mechanism, and between the height adjustment mechanism and the assembly plate 1, so as to adjust the angle of the height adjustment mechanism relative to the position adjustment mechanism and the angle of the assembly plate 1 relative to the height adjustment mechanism, so as to adjust the position and posture of the assembly plate 1 respectively.

[0049] The first information acquisition module is used to acquire the first angle information of the height adjustment mechanism relative to the position adjustment mechanism and the second angle information of the assembly plate relative to the height adjustment mechanism, respectively.

[0050] The second information acquisition module is used to acquire position information between two adjacent assembly plates;

[0051] A control device controls the first information acquisition module and the second information acquisition module to acquire information. The control device is also connected to the BIM system and a processor. Figure 1-9As shown, a BIM-based prefabricated building structure is constructed by mounting multiple prefabricated building structures on a pair of slide rails 2. The slide rails 2 can be configured as straight lines or curves relative to the surface to be constructed, providing bottom support for the assembly. To achieve the desired building surface shape, multiple prefabricated building structures are used, adjusting the positions and orientations of adjacent prefabricated panels to create the required surface shape. During assembly, a target building model is constructed using a BIM system. Then, multiple prefabricated building structures are used to assemble the required construction surface. After assembly, the BIM system, in conjunction with a measuring device, measures the assembled building model to verify its conformity with the target building model. If it does not conform, the positions and orientations of the multiple prefabricated building structures are readjusted to ensure conformity with the target building model constructed using the BIM system. For example, when constructing continuous inclined construction surfaces, graded inclined construction surfaces, or construction surfaces with alternating planes and inclined surfaces, the required construction surface is first constructed using the BIM system. The system generates parameters such as the installation position and posture of each building assembly structure. Based on these parameters, it adjusts the position and posture of each assembly structure to ensure that the construction surface formed by multiple assembly structures conforms to the target building model constructed by the BIM system. After assembly, the BIM system, in conjunction with a measuring device, is used for verification. The first information acquisition module acquires the first angle information of the height adjustment mechanism relative to the position adjustment mechanism and the second angle information of the assembly plate relative to the height adjustment mechanism in real time. The second information acquisition module acquires the position information between two adjacent assembly plates in real time. After processing by a processor connected to the control device, the real-time first angle information, second angle information, and position information of each building assembly structure are fed back to the BIM system. The BIM system checks the fit between the assembled building model and the target building model. When the assembled building model does not conform to the target building model, the BIM system generates adjustment values ​​for the position and posture of the corresponding building assembly structure based on the current assembled building model, and adjusts them to meet the requirements.

[0052] Specifically, the building assembly structure includes an assembly plate 1, a position adjustment mechanism, a height adjustment mechanism, a first adjustment mechanism, and a second adjustment mechanism. The assembly plate 1 can be a straight plane or a plane with curved sides, depending on the building to be constructed. The position adjustment mechanism adjusts the relative position of the assembly plate 1 on the slide rail 2. The height adjustment mechanism is installed between the assembly plate 1 and the position adjustment mechanism to adjust the height position of the assembly plate 1. The first and second adjustment mechanisms respectively adjust the angle of the height adjustment mechanism relative to the position adjustment mechanism and the angle of the assembly plate 1 relative to the height adjustment mechanism, thus changing the posture of the assembly plate 1 relative to the slide rail 2. At the same time, based on the adjustment of the height adjustment mechanism, the first and second adjustment mechanisms work together to adjust the height position of the assembly plate 1, allowing any construction surface to be built. In this process, the compatibility between multiple assembly plates 1 is also improved, and the assembly plate 1 can be adjusted accordingly after assembly.

[0053] In some embodiments, the position adjustment mechanism includes: a sliding seat 3, which is respectively disposed on a pair of slide rails 2. The bottom of each sliding seat 3 is provided with a pair of slide grooves 4 adapted to the slide rails 2. The sliding seat 3 is slidably connected to the slide rails 2 through the slide grooves 4. A pair of limiting holes 5 are provided on the sliding seat 3 above the slide grooves 4, and limiting screws 6 are respectively disposed in the limiting holes 5. Figure 1-9 As shown, the position adjustment mechanism includes a sliding seat 3, which is slidably connected to the guide rail via a slide groove 4 at its bottom to adjust the position of each building assembly structure as needed. The power input between the sliding seat 3 and the guide rail 2 can be done manually by a worker or by using a traction machine set at a fixed point. Each sliding seat 3 is individually fixed at a fixed point, and the traction machine provides power support to each of them, so that the positions of multiple sliding seats 3 on the guide rail can be changed. After being adjusted to the corresponding position, the limiting screw 6 is screwed into the limiting hole 5, so that the limiting screw 6 abuts against the guide rail 2, and the position of the sliding seat 3 relative to the guide rail 2 is fixed and limited.

[0054] In some embodiments, the first adjusting mechanism includes a first support 7, which is vertically disposed on the sliding seat 3. A first rotating rod 8 is vertically disposed at one end of the first support 7 near the sliding seat 3, and a second rotating rod 9 is vertically disposed at the other end of the first support 7 away from the sliding seat 3. The two ends of the second rotating rod 9 are rotatably connected to both sides of the first support 7. The two ends of the first rotating rod 8 rotatably pass through both sides of the first support 7. Triangular supports 10 are respectively disposed on both sides of the first support 7, and the triangular supports 10 are rotatably connected to the first rotating rod 8. A third rotating rod 11 is further disposed between the pair of triangular supports 10, and the two ends of the third rotating rod 11 are rotatably connected to the pair of triangular supports 10. The connection is such that a gap is provided between the third rotating rod 11 and the first support 7; the third rotating rod 11 is provided with a first through hole, and the second rotating rod 9 is provided with a second through hole; when the second rotating rod 9 and the third rotating rod 11 rotate until the openings of the first through hole and the second through hole face the same direction, the centers of the first through hole and the second through hole are on the same straight line; a first adjusting screw 12 is provided between the first through hole and the second through hole; one end of the first adjusting screw 12 is rotatably connected to the first through hole, and the other end of the first adjusting screw 12 is screwed to the second through hole; a first limiting part is provided at the end of the first adjusting screw 12 near the first through hole, and a first handle 13 is provided at the end of the first adjusting screw 12 near the second through hole. Figure 1-9 As shown, when adjusting the first adjusting mechanism, the first adjusting screw 12 is rotated relative to the second through hole of the second rotating rod 9 by operating the first handle 13, so as to change the relative distance between the second rotating rod 9 and the first rotating rod 8. When the relative distance changes, the triangular support 1 rotates around the first rotating rod 8, so that the base 23 on the triangular support 1 rotates with the first rotating rod 8 as the center, so as to adjust the angle between the base 23 and the sliding seat 3. The first limiting part of the first adjusting screw 12 near the first through hole prevents the first adjusting screw 12 from disengaging from the first through hole, so as to facilitate the change of the relative distance between the first rotating rod 8 and the second rotating rod 9.

[0055] In some embodiments, the second adjustment mechanism includes a second support 14, which is vertically disposed on the back of the mounting plate 1. A fourth rotating rod 15 is vertically disposed at one end of the second support 14 near the mounting plate 1, and a fifth rotating rod 16 is vertically disposed at the other end of the second support 14 near the mounting plate 1. The two ends of the fifth rotating rod 16 are rotatably connected to the two sides of the second support 14, respectively. The two ends of the fourth rotating rod 15 rotatably pass through the two sides of the second support 14. Triangular supports 17 are disposed on the two sides of the second support 14, respectively, and are rotatably connected to the fourth rotating rod 15. A sixth rotating rod 18 is also disposed between the pair of triangular supports 17, and the two ends of the sixth rotating rod 18 are respectively connected to the pair of triangular supports. The second support 14 is rotatably connected to the sixth rotating rod 18, with a gap between them. The sixth rotating rod 18 has a third through hole, and the fifth rotating rod 16 has a fourth through hole. When the fifth rotating rod 16 and the sixth rotating rod 18 rotate until the openings of the third and fourth through holes face the same direction, the centers of the third and fourth through holes are on the same straight line. A second adjusting screw 19 is provided between the third and fourth through holes. One end of the second adjusting screw 19 is rotatably connected to the third through hole, and the other end is screwed to the fourth through hole. A second limiting part is provided at the end of the second adjusting screw 19 near the third through hole, and a second handle 20 is provided at the end of the second adjusting screw 19 near the fourth through hole. Figure 1-9 As shown, during the adjustment process of the second adjustment mechanism, by operating the second handle 20, the second adjustment screw 19 is driven to rotate relative to the fourth through hole of the fifth rotating rod 16, so as to change the relative distance between the fifth rotating rod 16 and the fourth rotating rod 15. When the relative distance changes, the triangular support 2 rotates around the fourth rotating rod 15, so that the base plate 38 on the triangular support 2 rotates with the fourth rotating rod 15 as the center, so as to adjust the angle between the base plate 38 and the mounting plate 1. The second limiting part of the second adjustment screw 19 near the third through hole prevents the second adjustment screw 19 from disengaging from the third through hole, so as to facilitate the change of the relative distance between the fourth rotating rod 15 and the fifth rotating rod 16.

[0056] It should be noted that with the combined action of the first and second adjustment mechanisms, the angle adjustment between the assembly plate 1 and the slide rail 2 is more convenient. Furthermore, with the cooperation of the height adjustment mechanism, when the adjustment range of the height adjustment mechanism is limited, the cooperation of the first and second adjustment mechanisms can overcome the height position that the height adjustment mechanism cannot reach, so that the posture and height position of the assembly surface can reach the expected target.

[0057] In some embodiments, the height adjustment mechanism includes a fixed post, a telescopic cylinder 22, and an auxiliary connector. One end of the fixed post extends into the telescopic cylinder 22, and the auxiliary connector is detachably connected to the outside of the fixed post, such that the auxiliary connector abuts against one end of the telescopic cylinder 22. Figure 1-9 As shown, the height adjustment mechanism adjusts the height to the required level by changing the length between the fixed column and the telescopic cylinder 22 and fixing the position between the telescopic cylinder 22 and the fixed column through the auxiliary connector. The connection between the auxiliary connector and the outside of the fixed column can be in the form of screw connection, snap connection, etc.

[0058] In some embodiments, the fixing column includes: a base 23, which is detachably connected to the pair of triangular supports 10; a cylinder 21 is disposed on the base 23; a guide surface 24 is disposed at the end of the cylinder 21 away from the base 23; a cylindrical tube 25 is disposed at the end of the cylinder 21 away from the base 23; and an arc-shaped guide block 26 is disposed at the end of the cylindrical tube 25 away from the cylinder 21. The maximum radial dimension of the arc-shaped guide block 26 is the same as the radial dimension of the cylinder 21, and a gap is provided between the cylinder 21 and the inner wall of the telescopic cylinder 22. Figure 1-9 As shown, the fixed column includes a base 23. The connection between the base 23 and the triangular support 10 can be made by bolts. The guide surface 24 of the cylinder 21 away from the base 23 makes it easier to align when the fixed column and the telescopic cylinder 22 are assembled. The arc-shaped guide block 26 has the same effect. When the arc-shaped guide block 26 just contacts the opening of the telescopic cylinder 22, it can slide in smoothly. The maximum radial dimension of the arc-shaped guide block 26 is the same as the radial dimension of the cylinder 21. The gap between the cylinder 21 and the inner wall of the telescopic cylinder 22 is provided to allow the cylinder 21 to pass through smoothly.

[0059] In some embodiments, the inner wall of the telescopic cylinder 22 is provided with at least a pair of opposing first radial holes 27, second radial holes 28, and third radial holes 29. The first radial holes 27, second radial holes 28, and third radial holes 29 communicate sequentially from the inside of the telescopic cylinder 22 to the outside of the telescopic cylinder 22, penetrating the inner and outer sides of the telescopic cylinder 22. The diameters of the second radial holes 28, first radial holes 27, and third radial holes 29 decrease sequentially. A sliding block 30 is provided in the first radial hole 27. One end of the moving block 30 extends out of the first radial hole 27 and is provided with a downwardly inclined sliding surface 31. A sliding rod 32 is provided in the third radial hole 29. One end of the sliding rod 32 passes through the second radial hole 28 and is connected to the sliding block 30. The other end of the sliding rod 32 passes out of the third radial hole 29 to the outside of the telescopic cylinder 22 and is connected to a limiting member 33. A spring 41 is sleeved on the sliding rod 32. One end of the spring 41 abuts against the sliding block 30, and the other end of the spring 41 abuts against the inner wall of the second radial hole 28.

[0060] A sliding ring 34 is fitted on the cylindrical tube 25. The sliding ring 34 is slidably connected to the cylindrical tube 25. The top and bottom of the sliding ring 34 are respectively provided with a first sliding surface 35 and a second sliding surface 36. The maximum radial dimension of the sliding ring 34 is the same as the inner diameter of the telescopic tube 22.

[0061] The telescopic cylinder 22 has an arc-shaped sliding surface 37 at one end near the arc-shaped guide block 26, and a base plate 38 at the other end away from the arc-shaped guide block 26. The base plate 38 is detachably connected to a pair of triangular supports 17. Figure 1-9 As shown, the first radial hole 27, the second radial hole 28, and the third radial hole 29 are sequentially arranged from the inside to the outside of the telescopic cylinder 22 to form a connecting channel. The diameters of the second radial hole 28, the first radial hole 27, and the third radial hole 29 decrease sequentially. A sliding block 30 is provided in the first radial hole 27. One end of the sliding block 30 extending into the telescopic cylinder 22 is provided with an inclined downward sliding surface 31. The sliding rod 32 at the other end of the sliding block 30 is slidably connected to the third radial hole 29. When the... When force is applied to the sliding block 30 inside the telescopic cylinder 22, the sliding block 30 slides into the second radial hole 28. The spring 41 on the sliding rod 32 abuts against the inner wall of the sliding block 30 and the second radial hole 28. When the sliding block 30 slides into the second radial hole 28, the spring 41 is compressed. After the applied force is removed, the spring 41 helps it to return to its original position. At the same time, the limiting member 33 limits the other end of the sliding rod 32. The limiting member 33 can be a round or square block with a size larger than the third radial hole 29.

[0062] Specifically, when the arc-shaped guide block 26 moves inward from the opening of the telescopic cylinder 22, its arc-shaped guide block contacts the sliding surface 31 of the sliding block 30. When the arc-shaped guide block 26 continues to move inward into the telescopic cylinder 22, its sliding block 30 slides in the first radial hole 27, causing the sliding rod 32 to slide outward from the telescopic cylinder 22, which in turn compresses the spring 41. When the arc-shaped guide block 26 disengages from the sliding surface 31, since there is no longer any restriction on the sliding block 30, the spring 41 returns to its original deformation. At this time, the sliding block 30 extends into the space formed by the cylindrical cylinder 25 and the inner wall of the telescopic cylinder 22. At this time, the distance between the telescopic cylinder 22 and the fixed column cannot be increased further because the sliding block 30 restricts the arc-shaped guide block 26, and the maximum distance between the telescopic cylinder 22 and the fixed column at this point is limited.

[0063] Specifically, when it is necessary to adjust the maximum distance between the telescopic cylinder 22 and the fixed column, the arc-shaped guide block 26 is continued to slide into the telescopic cylinder 22, causing the guide surface 24 to contact the first sliding surface 35 of the sliding ring 34, and causing the sliding ring 34 to pass through the sliding block 30. This process is the same as the principle of the arc-shaped guide block 26 passing through. Afterwards, the sliding block 30 slides along the second sliding surface 36 of the sliding ring 34. Then, the operation is performed in the opposite direction to increase the distance between the telescopic cylinder 22 and the fixed column. At this time, the sliding block 30 moves towards the sliding ring 34 on the second sliding surface 36. The sliding ring 34 slides upwards, causing it to slide towards the arc-shaped guide block 26. When it comes into contact with the arc-shaped guide block 26, the maximum radial dimension of the sliding ring 34 is larger than the maximum radial dimension of the arc-shaped guide block 26, causing the sliding surface 31 of the sliding block 30 to slide on the first sliding surface 35. The sliding block 30 then slides into the first radial hole 27 until it is fully inserted into the first radial hole 27, allowing the arc-shaped guide block 26 to pass through the sliding block 30. The limit between the arc-shaped guide block 26 and the sliding block 30 is released, and the maximum distance between the telescopic cylinder 22 and the fixed column can be restored.

[0064] Specifically, multiple sliding blocks 30 are evenly arranged on the inner wall of the telescopic cylinder 22. The first sliding block 30 passes through the opening of the telescopic cylinder 22 using an arc-shaped guide block 26 and slides to the corresponding sliding block 30 inside the telescopic cylinder 22. The maximum distance of the sliding block 30 at that location is limited by the sliding block 30. Then, the position of the fixing column and the telescopic cylinder 22 is limited by the auxiliary connector, so that the relative position between the fixing column and the telescopic cylinder 22 is fixed. When the assembly plate 1 needs to be adjusted, it can be moved to the corresponding position relatively easily. At the same time, a limiting range is formed between different sliding blocks 30. When fine adjustment is needed after assembly, it can control the adjustment range and make it easier to adjust the height position of the assembly plate 1.

[0065] Specifically, based on the height adjustment, the first and second adjustment mechanisms are used to make fine adjustments to the distance that cannot be reached between each sliding block 30 within the adjustment range. The coordination between the first and second adjustment mechanisms allows the angle of the fixed column relative to the sliding seat 3 to change while keeping the target angle of the assembly plate 1 unchanged, so as to adjust the corresponding height between the two sliding blocks 30.

[0066] In some embodiments, the auxiliary connector includes a sleeve 39, the outer side of the cylinder 21 is provided with a first thread, the inner side of the sleeve 39 is provided with a second thread, the sleeve 39 and the cylinder 21 are screwed together by the first thread and the second thread, and the outer side of the sleeve 39 is provided with a stop portion 40, the stop portion 40 extending outward from the sleeve. Figure 1-9 As shown, after the relative positions of the cylinder 21 and the telescopic cylinder 22 are adjusted, the sleeve 39 is screwed to the cylinder 21 to move to the corresponding position, so that the abutment part 40 abuts against the bottom of the telescopic cylinder 22. After the sliding block 30 limits the arc-shaped guide block 26, the abutment part 40 further limits the telescopic cylinder 22 to limit the distance between the telescopic cylinder 22 and the cylinder 21.

[0067] In some embodiments, the first information acquisition module includes a first attitude sensor and a second attitude sensor, which are respectively connected to the processor to obtain first angle information and second angle information, respectively. The first attitude sensor is disposed at the center of the base, and the second attitude sensor is disposed at the center of the assembly plate.

[0068] The second information acquisition module includes a displacement sensor connected to the processor to obtain positional information between two adjacent assembly plates. The displacement sensor is positioned at the center of the assembly plate. Figure 1-9As shown, the first information acquisition module includes a first attitude sensor and a second attitude sensor, both commercially available. The second information acquisition module includes a displacement sensor, also commercially available. The first attitude sensor is located at the center of the base 23, and the second attitude sensor is located at the center of the assembly plate 1. After processing by the processor, first angle information and second angle information are obtained to obtain the angle between the base 23 and the guide rail, and the angle between the assembly plate 1 and the guide rail, respectively. This allows for adjustment of the attitude of the assembly plate 1, facilitating coordination with the height adjustment mechanism to adjust the attitude and height position of the assembly plate 1 using the first and second adjustment mechanisms. The displacement sensor acquires the position signals of two adjacent building assembly structures. After processing by the processor, the position information between two adjacent assembly plates is obtained. Combined with the first and second angle information, once the first and second angle information corresponding to each building assembly structure is obtained, the height position and position relative to the sliding seat 3 of the assembly plate 1 can be calculated based on the known parameters of the building assembly structure. For example, once the length of the assembly plate is known, its projection length on the sliding seat can be obtained through trigonometric functions. Thus, the position information of each assembly plate 1 is obtained. When displaying each building assembly structure in real time, the position and posture information of each assembly plate 1 are displayed in the BIM system to obtain the posture and position information of each building assembly structure after assembly. This information is compared with the target building model to verify the fit between the assembled building model and the target building model generated by the BIM system. When the assembled building model does not conform to the target building model, the BIM system generates corresponding adjustment values ​​for the position and posture of the building assembly structure based on the current assembled building model. The position adjustment mechanism, height adjustment mechanism, and the first and second adjustment mechanisms are adjusted according to the corresponding adjustment values. Specifically, when adjusting the height, if the height to be adjusted cannot reach the adjustment range between the two sliding blocks, the first and second adjustment mechanisms can be used in conjunction to change the angle of the fixed column relative to the sliding seat 3 while keeping the target angle of the assembly plate 1 unchanged, so as to adjust to the corresponding height between the two sliding blocks 30. During this process, the adjustment range of the height adjustment through the cooperation of the first and second adjustment mechanisms is included in the posture adjustment value range generated by the BIM system. Accordingly, the assembled building model is verified and adjusted after assembly to achieve the target building model.

[0069] The present invention also provides a BIM-based building assembly method, employing the BIM-based building assembly structure described in the preceding claim, comprising the following steps:

[0070] S1: Use the BIM system to generate the target building model. The BIM system selects the required number of building assembly structures based on the target building model and generates the first angle information, second angle information, and location information for each building assembly structure.

[0071] S2: Adjust the position adjustment mechanism, height adjustment mechanism, first adjustment mechanism and second adjustment mechanism of each building assembly structure according to the first angle information, second angle information and position information of each building assembly structure, so that the construction surface of each assembly plate after assembly matches the target building model.

[0072] S3: Reacquire the first angle information, second angle information, and position information of each assembled building structure after assembly, and use the BIM system to verify each assembled panel after assembly.

[0073] Specifically, for example, when constructing a staircase construction surface, a BIM system, such as Autodesk Revit, is used to generate the required number of prefabricated panels based on the surface shape of the building to be constructed and the specifications of the existing prefabricated panels. Simultaneously, the BIM system generates the first angle information, second angle information, and position information for each prefabricated structure. In the target building model generated by the BIM system, each prefabricated structure is presented with a construction surface, such as a continuous inclined surface, a graded inclined surface, or a construction surface with alternating planes and inclined surfaces. After the BIM system generates the first angle information, second angle information, and position information for each prefabricated structure, the corresponding prefabricated structure is installed using this information.

[0074] Specifically, based on the first angle information, second angle information, and position information of each building assembly structure, the position adjustment mechanism, height adjustment mechanism, first adjustment mechanism, and second adjustment mechanism of each building assembly structure are adjusted respectively. The position adjustment mechanism adjusts the relative distance between each building assembly structure, and the height adjustment mechanism adjusts the position of the assembly plate 1 accordingly. Based on the height adjustment mechanism, the first and second adjustment mechanisms work together to ensure that the assembly plate 1 fits the preset construction surface, while adjusting the first and second adjustment mechanisms to adjust the range that the height adjustment mechanism cannot adjust. With their joint cooperation, the height and posture of the assembly plate 1 are ensured so that each assembly plate 1 adapts to the constructed construction surface, and the construction surface after assembly of each assembly plate matches the target building model.

[0075] Specifically, after multiple assembly panels 1 are assembled, the first angle information, second angle information, and position information of each assembled building structure are reacquired. The acquired signals are transmitted to the processor in real time through the first attitude sensor, second attitude sensor, and displacement sensor of each assembled building structure. After the processor calculates, it generates the first angle information, second angle information, and position information of each assembled building structure and transmits them to the BIM system. The BIM system displays the assembled building model on the target building model. The BIM system checks the fit between the assembled building model and the target building model. If the assembled building model and the target building model do not fit, the BIM system generates the corresponding adjustment values ​​for the position and attitude of the assembled building structure based on the current assembled building model. Then, the position adjustment mechanism, height adjustment mechanism, first adjustment mechanism, and second adjustment mechanism of the assembled building structure that need to be modified and adjusted are adjusted accordingly.

[0076] Specifically, during height adjustment, when the height deviation adjustment value is greater than the distance between the two sliding blocks 30, the height adjustment mechanism is adjusted first, followed by the adjustment of the first and second adjustment mechanisms based on the height adjustment mechanism. When the height to be adjusted cannot reach the adjustment range between the two sliding blocks, the first and second adjustment mechanisms can be used in conjunction to change the angle of the fixed column relative to the sliding seat 3 while keeping the target angle of the assembly plate 1 unchanged, thereby adjusting to the corresponding height between the two sliding blocks 30. During this process, the height adjustment range achieved through the cooperation of the first and second adjustment mechanisms is included within the attitude adjustment value range generated by the BIM system. Accordingly, the assembled building model is verified and adjusted after assembly to ensure that the assembled building model achieves the expected goals.

The above description is only a preferred embodiment of the present invention.
