[0002] Building Information Modeling (BIM) is a new tool in architecture, engineering and civil engineering. The term Building Information Modeling or Building Information Modeling was coined by Autodesk. Prefabricated buildings refer to the transfer of a large number of on-site operations in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on site through reliable connections.

[0003] In the prior art, a BIM-based prefabricated building component is disclosed with patent announcement number CN218437737U. When the assembly of the above patent is connected longitudinally, the supporting ribs of the longitudinal connector are cast inside to improve the structural strength of the longitudinal connection. When the assembly is connected transversely, the supporting ribs of the transverse connector are cast inside to improve the structural strength of the transverse connection. However, the following deficiencies still exist in actual use: From a practical point of view, the BIM-based prefabricated building component is a cast-in-place fixed connector, which requires a long time for concrete cooling, and the strength of the cast-in-place connector alone is not enough, which affects the later life of the building.

[0004] Therefore, there is a need for a BIM-based prefabricated building component to solve the problems existing in the prior art. Utility Model Content

[0009] It should be further explained that the first fixing holes or the second fixing holes of the plurality of regular ones are arranged in the middle of the space where the plurality of regular longitudinal ribs and the plurality of regular transverse ribs intersect.

[0010] As a preferred embodiment, the upper ends of the connecting members described in some rules are provided with sliding grooves on both sides of the second connecting groove. The sliding grooves are arc-shaped, and the arc-shaped sliding grooves are fitted with angle irons for sliding connection. The angle irons are arc-shaped and are fitted with sliding connection on the inner surface of the sliding groove.

[0011] As a preferred embodiment, the several symmetrical raised guides are all arc-shaped, and the several symmetrical raised guides are all fitted and slidably connected to the outer surface of the angle iron at the upper ends of both sides of the second connecting groove.

In addition, the plurality of connecting members will be directly hidden between the prefabricated wall panels on both sides, thereby enhancing the aesthetics of the plane after the plurality of prefabricated wall panels are connected.

[0015] (2) One end of the arc angle iron is squeezed through the protruding guide at the lower end of the connecting piece. When the protruding guide at the lower end of the connecting piece is fitted with the lowest end of the second connecting groove at the upper end of the connecting piece, the other end of the arc angle iron is fitted with the limiting grooves on both sides of the protruding guide, thereby making the stability between the two connecting pieces higher, thereby increasing the practicality of the BIM-based prefabricated building component.

[0024] Further as Figure 4As shown, it is worth explaining in detail that the several regular steel bars 4 include several regular longitudinal bars 401 and several regular transverse bars 402, and the outer surfaces of the several regular longitudinal bars 401 and the several regular transverse bars 402 are fitted and fixedly connected with several regular stirrups 5. Through the several regular longitudinal bars 401 and the several regular transverse bars 402, the several connecting pieces 2 and the prefabricated wall panels 1 can be fixedly connected through the several regular bolts 3, that is, the several regular connecting pieces 2 fix the prefabricated wall panels 1 on both sides, which not only enhances the strength of the connecting pieces 2, but also makes the fixation of the prefabricated wall panels 1 on both sides more stable.

[0025] This scheme has the following working process: first, place a plurality of connecting parts 2 in the first connecting groove 101 between the symmetrical prefabricated wall panels 1, and at the same time, the protruding guide 202 at the lower end of the connecting part 2 will squeeze one end of the arc angle iron 7. When the protruding guide 202 at the lower end of the connecting part 2 fits with the bottom of the second connecting groove 201 at the upper end of the connecting part 2, the other end of the arc angle iron 7 fits with the limiting grooves 2021 on both sides of the protruding guide 202. Then, a plurality of bolts 3 are all fitted and slidably connected to the plurality of regular first fixing holes 102 or the second fixing holes 203 in the middle of the space where a plurality of regular longitudinal ribs 401 and a plurality of regular transverse ribs 402 intersect. Finally, the nuts 301 on both sides of the bolts 3 can be installed.

[0026] According to the above working process, it can be known that: bolts 3 are fitted and slidably arranged through a plurality of regular first fixing holes 102 and second fixing holes 203, so that the prefabricated wall panels 1 and the connecting parts 2 can be fixed to each other, and a plurality of connecting parts 2 will be directly hidden between the prefabricated wall panels 1 on both sides, thereby enhancing the aesthetics of the plane after the plurality of prefabricated wall panels 1 are connected, and a plurality of regular longitudinal ribs 401 and a plurality of regular transverse ribs 402 can be used to fix the plurality of connecting parts 2 and the prefabricated wall panels 1 with a plurality of regular bolts 3, that is, a plurality of regular connecting parts 2 fix the prefabricated wall panels 1 on both sides, thereby not only enhancing the strength of the connecting parts 2, but also making the fixation of the prefabricated wall panels 1 on both sides more stable.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the plurality of regular first fixing holes 102 or the second fixing holes 203 are arranged in the middle of the space where the plurality of regular longitudinal ribs 401 and the plurality of regular transverse ribs 402 intersect. By arranging the plurality of regular first fixing holes 102 or the second fixing holes 203 at the positions of the connecting member 2, the strength of the connecting member 2 can be increased, thereby increasing the connection strength between the prefabricated wall panel 1 and the connecting member 2, and further increasing the stability of the BIM-based prefabricated building component.

[0028] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth explaining in detail that the upper ends of several regular connecting members 2 are provided with sliding grooves 6 on both sides of the second connecting groove 201, the sliding grooves 6 are arc-shaped, and the arc-shaped sliding grooves 6 are fitted with angle irons 7 for sliding connection, the angle irons 7 are arc-shaped, and are fitted with sliding connection to the inner surface of the sliding grooves 6, and the sliding grooves 6 can limit the position and movement trajectory of the arc-shaped angle irons 7.

[0029] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the several symmetrical protrusion guides 202 are all arc-shaped, and the arc-shaped several symmetrical protrusion guides 202 are all fitted and slidably connected to the outer surface of the angle iron 7 on the upper ends of both sides of the second connecting groove 201. Through the shape and position of the several symmetrical protrusion guides 202, the angle iron 7 on the upper ends of both sides of the second connecting groove 201 can be restricted and fixed, thereby increasing the stability between the two interconnected parts 2.

[0030] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that a plurality of raised guides 202 are all fitted and slidably connected to the second connecting groove 201, and the outer surfaces at both ends of the symmetrical nut 301 are parallel to the outer surfaces at both sides of the prefabricated wall panel 1. Through the positions of the outer surfaces at both ends of the symmetrical nut 301 and the outer surfaces at both sides of the prefabricated wall panel 1, the smoothness of the plane after the prefabricated wall panel 1 is connected can be increased, thereby facilitating the subsequent processes of the prefabricated wall panel 1.

[0031] In summary: first, place a plurality of connectors 2 in the first connecting groove 101 between the symmetrical prefabricated wall panels 1, and at the same time, the protruding guide 202 at the lower end of the connector 2 will squeeze one end of the arc angle iron 7. When the protruding guide 202 at the lower end of the connector 2 fits with the lowest end of the second connecting groove 201 at the upper end of the connector 2, the other end of the arc angle iron 7 fits with the limiting grooves 2021 on both sides of the protruding guide 202.

The sliding groove 6 can limit the position and movement trajectory of the arc angle iron 7. The shapes and positions of the plurality of symmetrical raised guides 202 can limit and fix the angle irons 7 at the upper ends of both sides of the second connecting groove 201, thereby increasing the stability between the two interconnected members 2. The positions of the outer surfaces at both ends of the symmetrical nuts 301 and the outer surfaces at both sides of the prefabricated wall panel 1 can increase the smoothness of the plane after the prefabricated wall panel 1 is connected, thereby facilitating the subsequent processes of the prefabricated wall panel 1.
