Description

Technical Field

[0001] This invention relates to the field of prefabricated wall panel mechanism technology, and in particular to a prefabricated wall panel mechanism based on BIM building construction. Background Technology

[0002] Prefabricated wall panels are a new type of wall material that integrates structural and decorative functions. They replace traditional brick-concrete structural walls and building decoration materials that simply use gypsum board, MDF, paint, etc.

[0003] Prefabricated wall panels are integrated wall products that are typically manufactured using dry construction methods, produced in factories, and assembled on-site. They are suitable for non-load-bearing partition wall designs in interior spaces such as living rooms, bedrooms, kitchens, and bathrooms in civil buildings.

[0004] Current prefabricated wall panels are only connected with cement or other materials at the joints, which is not strong enough. In addition, the square wall panels are not easy to move during assembly. Therefore, there is still room for improvement.

[0005] A search revealed Chinese patent application number CN202220800637.9, which discloses a prefabricated steel structure wall panel connection device, relating to the field of steel structure wall panel technology. This prefabricated steel structure wall panel connection device includes a steel structure wall panel A, a ground insertion mechanism, and a connection mechanism. A steel structure wall panel B is mounted on steel structure wall panel A. The ground insertion mechanism is located at the bottom of both steel structure wall panels A and B. The ground insertion mechanism includes a threaded rod, a ground plug, and a handle. The bottom of the threaded rod is fixedly connected to the ground plug, and the top of the threaded rod is fixedly connected to the handle. The connection mechanism is located between steel structure wall panels A and B and includes a sliding plate, a plug rod, and a spring. There are two sets of sliding plates, each with a plug rod fixedly connected to one side. A spring is fixedly connected between the two sets of sliding plates. The prefabricated steel structure wall panel connection device in the aforementioned patent has the following shortcomings: the use of a spring structure connection results in insufficient reliability, and the square wall panels are not easy to move during assembly, requiring further improvement. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a prefabricated wall panel mechanism based on BIM building construction.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A BIM-based prefabricated wall panel structure for building construction includes multiple interlocking wall panel bodies. Each wall panel body has an opening in the center of both sides, forming an "I"-shaped structure based on the openings. The wall panel bodies are connected to each other via an interlocking mechanism, which includes:

[0009] The filler block is sized to fit the dimensions of the two merged openings;

[0010] The reinforcing plate has an insert plate on one side, and a side groove adapted to the insert plate is opened at the opening of the wall panel body. The reinforcing plate is installed in the side groove through the insert plate, and limit brackets are provided on both sides of the reinforcing plate.

[0011] The connecting plate has two mounting holes and is slidably connected to the limiting bracket. The wall panel body has a first slot that matches the connecting plate, and the filling block has a second slot that matches the connecting plate.

[0015] Corner reinforcement plate: The corner reinforcement plate is fixed at the corner of the main body of the wall panel. The corner reinforcement plate is provided with corner reinforcement mechanism. The four corner reinforcement mechanisms are spliced ​​together to form a ring structure.

[0016] The arc-shaped connecting plate has an arc-shaped structure and is slidably connected to the corner reinforcement mechanism.

[0017] As a preferred embodiment of the present invention, the connecting plate has a T-shaped structure.

[0018] As a preferred embodiment of the present invention, the wall panel body is provided with reinforcing ribs.

[0019] As a preferred embodiment of the present invention: an auxiliary support mechanism is provided at the bottom of the wall panel body, the auxiliary support mechanism comprising:

[0020] The annular screw seat has an installation cavity at the bottom of the wall panel body, and the top of the annular screw seat is installed in the installation cavity;

[0021] The base plate is fixed to the outer wall of the bottom of the annular screw seat, and the width of the base plate is less than the thickness of the main body of the wall panel.

[0022] As a preferred embodiment of the present invention: A positioning cylinder is detachably installed in the installation cavity. A plurality of arc-shaped elastic pieces distributed circumferentially are fixed to the top of the positioning cylinder. The arc-shaped elastic pieces are in a "丿" - shaped structure. A plurality of anti-slip blocks are provided on the side wall of the arc-shaped elastic pieces, and the top ends of the arc-shaped elastic pieces converge inward.

[0023] A connecting cylinder is slidably connected in the positioning cylinder, and an annular screw seat is threadedly connected to the inner wall of the connecting cylinder.

[0024] As a preferred embodiment of the present invention: An annular groove is provided on the inner side of the positioning cylinder. A limiting ring is provided on the circumferential outer wall of the connecting cylinder, and the connecting cylinder slides in the annular groove through the limiting ring.

[0025] As a preferred embodiment of the present invention: A plurality of positioning grooves are provided at the bottom of the wall panel main body, and the positioning grooves are located outside the bottom of the installation cavity. A positioning block adapted to the positioning grooves is provided on the bottom side wall of the positioning cylinder, and the positioning block is snap-fitted into the positioning grooves.

[0026] As a preferred embodiment of the present invention: A clamping groove is provided at the top of the wall panel main body, and the width of the clamping groove is adapted to the width of the bottom plate.

[0027] As a preferred embodiment of the present invention: The construction method of the prefabricated wall panel mechanism includes the following steps:

[0028] S1: Adjust the effective length of the annular screw seat and the connecting cylinder;

[0029] S2: Groove the ground at the assembly location so that the groove is adapted to the shape of the bottom plate;

[0030] S3: Apply cement preliminarily at the assembly location;

[0031] S4: Carry the wall panel main body to the designated position, align it, and embed the bottom plate into the groove on the ground;

[0032] S5: Position another wall panel main body to one side of this wall panel main body in the same way as above, so that the openings of the two wall panel main bodies are aligned;

[0033] S6: Place the filling block in the combined openings of the two;

[0034] S7: Then move one end of the connecting plate into the second groove, so that the positions of the two assembly holes are respectively adapted to the through holes and the screw cylinders, and then fix them with fixing bolts;

[0035] S8: Slide the arc-shaped connecting plate in the arc-shaped groove to connect and reinforce between adjacent two corner reinforcement plates;

[0036] S9: Perform cement construction for filling and reinforcement.

[0037] The beneficial effects of the present invention are:

[0038] 1. The present invention, by setting the wall panel body with an "I" shaped structure, makes it easier for equipment to transport it. The splicing mechanism can place the filling block in the two merged openings during splicing, and then move one end of the connecting plate into the second slot so that the positions of the two assembly holes are adapted to the through hole and the screw cylinder respectively. Then, it is fixed by fixing bolts, thereby achieving the purpose of splicing and reinforcement.

[0039] 2. During the handling and alignment process before splicing, the present invention can protect the main body of the wall panel by setting up a reinforcing plate and other structures, preventing the equipment from damaging the main body of the wall panel. In addition, since the length of the first slot is greater than or equal to the length of the connecting plate, the connecting plate can be hidden in the first slot, so that the handling equipment can better clamp the end face of the reinforcing plate, thereby improving reliability.

[0040] 3. By setting up a corner reinforcement mechanism, the present invention can slide the arc-shaped connecting plate into the arc-shaped groove during splicing, thereby realizing the connection and reinforcement between two adjacent corner reinforcement plates.

[0041] 4. By setting up an auxiliary support mechanism, the present invention can rotate the base plate to a state parallel to the main body of the wall panel during transportation to facilitate transportation. During assembly, the base plate can be rotated to a state perpendicular to the main body of the wall panel. The base plate and the main body of the wall panel form a cross-shaped structure, thereby ensuring the firmness of the structure after assembly.

[0042] 5. By incorporating structures such as arc-shaped springs and connecting cylinders, this invention allows the top of the connecting cylinder to move towards the arc-shaped springs during assembly, based on the downward pressure of the wall panel's own weight. This causes the arc-shaped springs to expand outwards, and the anti-slip block to contact the inner wall of the mounting cavity, achieving the purpose of anti-slip and anti-detachment, thus ensuring the stability of the structure. Furthermore, since the final position of the top of the connecting cylinder may vary, the annular screw seat, which is adjustable via threads and mounted on the inner wall of the connecting cylinder, allows for adjustment of the effective length of the annular screw seat and the connecting cylinder as a whole, according to actual needs. This ensures that the wall panel's final state is horizontal, improving reliability.

[0043] 6. By setting an annular groove and a limiting ring, the present invention can limit the connecting cylinder to prevent it from falling off, thus improving its practicality; by setting a positioning groove and other structures, the positioning cylinder can be positioned to prevent it from rotating on its own, thus improving its reliability.

[0053] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0054] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0055] Example 1:

[0056] A BIM-based prefabricated wall panel structure for building construction, such as Figure 1-8As shown, the wall panel includes multiple interlocking wall panel bodies 1. Each wall panel body 1 has an opening in the center of both sides, forming an "I"-shaped structure based on the openings. The wall panel bodies 1 are connected to each other via an interlocking mechanism, which includes:

[0057] Filler block 4, the size of filler block 4 is adapted to the size of the two merged openings;

[0058] The reinforcing plate 20 has an integral insert plate 19 on one side. The wall panel body 1 has a side groove 7 that matches the insert plate 19 at the opening. The reinforcing plate 20 is installed in the side groove 7 through the insert plate 19. Limiting brackets 15 are integrally provided on both sides of the reinforcing plate 20.

[0059] The connecting plate 13 has two mounting holes and is slidably connected to the limiting bracket 15. The wall panel body 1 has a first slot 2 that matches the connecting plate 13, and the filling block 4 has a second slot 14 that matches the connecting plate 13. The first slot 2 has a through hole 17, and the insert plate 19 has a screw hole 18 that matches the through hole 17. The screw hole 18 and the through hole 17 match one of the mounting holes of the connecting plate 13.

[0060] Screw 21 is embedded in the second slot 14 and is adapted to another mounting hole of the connecting plate 13.

[0061] When the filling block 4 is installed in the two merged openings, the distance from the screw cylinder 21 to the screw hole 18 is adapted to the spacing of the two assembly holes. The length of the first slot 2 is greater than or equal to the length of the connecting plate 13. The connecting plate 13 is fixed to the wall panel body 1 and the filling block 4 by two fixing bolts 16.

[0062] By setting the wall panel body 1 with an "I" shaped structure, it is easier for equipment to handle it. The splicing mechanism can place the filling block 4 into the two merged openings during splicing, and then move one end of the connecting plate 13 into the second slot 14 so that the positions of the two assembly holes are adapted to the through hole 17 and the screw cylinder 21 respectively. Then, it is fixed by the fixing bolt 16, thereby achieving the purpose of splicing and reinforcement.

[0063] In addition, during the handling and alignment process before splicing, the reinforcing plate 20 and other structures can protect the wall panel body 1 and prevent the equipment from damaging the wall panel body 1. Furthermore, since the length of the first slot 2 is greater than or equal to the length of the connecting plate 13, the connecting plate 13 can be hidden in the first slot 2, so that the handling equipment can better clamp the end face of the reinforcing plate 20, thus improving reliability.

[0064] To improve connection strength; such as Figure 1 , Figure 4As shown, a corner reinforcement mechanism 10 is provided at the corner of the wall panel main body 1. The corner reinforcement mechanism 10 includes:

[0065] Corner reinforcement plates 5 are fixed at the corners of the wall panel main body 1. Corner reinforcement grooves 10 are formed on the corner reinforcement plates 5, and four corner reinforcement mechanisms 10 are spliced to form an annular structure;

[0066] Arc-shaped connecting plates 9 are in an arc-shaped structure, and the arc-shaped connecting plates 9 are slidably connected within the corner reinforcement mechanism 10;

[0067] By providing the corner reinforcement mechanism 10, when splicing, the arc-shaped connecting plate 9 can be slid within the arc-shaped groove 12, thereby realizing the connection and reinforcement between two adjacent corner reinforcement plates 5.

[0068] To improve reliability; as Figure 5 shown, the connecting plate 13 is in a T-shaped structure.

[0069] To improve the structural strength; as Figure 3 shown, reinforcing ribs 8 are provided within the wall panel main body 1.

[0070] Embodiment 2:

[0071] A prefabricated wall panel mechanism for BIM building construction, as Figure 1-8 shown, to improve the installation firmness; the following improvements are made to this embodiment based on Embodiment 1: An auxiliary support mechanism is provided at the bottom of the wall panel main body 1. The auxiliary support mechanism includes:

[0072] An annular screw base 22 is provided in an installation cavity 24 opened at the bottom of the wall panel main body 1, and the top of the annular screw base 22 is installed within the installation cavity 24; [[ID=�2]]

[0073] A bottom plate 3 is fixed to the outer wall at the bottom of the annular screw base 22, and the width of the bottom plate 3 is smaller than the thickness of the wall panel main body 1;

[0074] By providing the auxiliary support mechanism, during transportation, the bottom plate 3 can be rotated to a state parallel to the overall wall panel main body 1 for easy transportation. When assembling, the bottom plate is rotated to a state perpendicular to the overall wall panel main body 1, and the bottom plate 3 and the wall panel main body 1 form a cross-shaped structure, thereby ensuring the firmness of the structure after assembly.

[0075] To achieve the purpose of anti-disengagement; as Figure 7 、 Figure 8 shown, a positioning cylinder 30 is detachably installed within the installation cavity 24. A plurality of circumferentially distributed arc-shaped elastic pieces 26 are fixed to the top of the positioning cylinder 30. The arc-shaped elastic pieces 26 are in a '丿'-shaped structure. A plurality of anti-sliding blocks 6 are provided on the side walls of the arc-shaped elastic pieces 26, and the tops of the arc-shaped elastic pieces 26 converge inwardly;

[0076] The positioning cylinder 30 is slidably connected to the connecting cylinder 23, and the annular screw seat 22 is threadedly connected to the inner wall of the connecting cylinder 23.

[0077] By setting up structures such as the arc-shaped spring piece 26 and the connecting cylinder 23, during assembly, the top of the connecting cylinder 23 can move towards the arc-shaped spring piece 26 based on the downward pressure of the wall panel body 1 itself. This causes the arc-shaped spring piece 26 to expand outward, and the anti-slip block 6 to contact the inner wall of the mounting cavity 24, achieving the purpose of anti-slip and anti-detachment, thus ensuring the stability of the structure. Furthermore, since the final position of the top of the connecting cylinder 23 may vary, the annular screw seat 22 is installed on the inner wall of the connecting cylinder 23 in an adjustable manner through the thread. This allows the effective length of the annular screw seat 22 and the connecting cylinder 23 to be adjusted according to actual needs, thereby ensuring that the wall panel body 1 is ultimately horizontal, thus improving reliability.

[0078] To limit the structure; such as Figure 8 As shown, the positioning cylinder 30 has an annular groove 27 on its inner side, and the connecting cylinder 23 has an integrally formed limiting ring 28 on its outer circumference. The connecting cylinder 23 slides in the annular groove 27 through the limiting ring 28.

[0079] By setting the annular groove 27 and the limiting ring 28, the connecting cylinder 23 can be limited to prevent it from falling off, thus improving its practicality.

[0080] For ease of location; such as Figure 7 As shown, the bottom of the wall panel body 1 is provided with multiple positioning grooves 25. The positioning grooves 25 are located on the outer side of the bottom of the mounting cavity 24. The bottom side wall of the positioning cylinder 30 is integrally provided with a positioning block 29 that is adapted to the positioning groove 25. The positioning block 29 is snapped into the positioning groove 25.

[0081] By setting up structures such as the positioning groove 25, the positioning cylinder 30 can be positioned, preventing the positioning cylinder 30 from rotating on its own and improving reliability.

[0082] To facilitate splicing; such as Figure 3 , Figure 4 As shown, the top of the wall panel body 1 is provided with a slot 11, the width of which is adapted to the width of the base plate 3.

[0083] For reliable construction, the construction method of the prefabricated wall panel mechanism includes the following steps:

[0084] S1: Adjust the effective length of the annular screw seat 22 and the connecting cylinder 23;

[0085] S2: Cut a groove in the ground at the assembly point so that the groove matches the shape of the base plate 3;

[0086] S3: Apply cement or other bonding materials to the assembly area initially;

[0087] S4: Move the wall panel body 1 to the designated position and align it so that the base plate 3 is embedded into the groove in the ground;

[0088] S5: Position the other wall panel body 1 to one side of the wall panel body 1 using the same method as described above, so that the openings of the two wall panel bodies 1 are aligned.

[0089] S6: Place filler block 4 within the two merged openings;

[0090] S7: Move one end of the connecting plate 13 into the second slot 14 so that the positions of the two assembly holes are adapted to the through hole 17 and the screw cylinder 21 respectively, and then fix them with the fixing bolt 16.

[0091] S8: Slide the arc-shaped connecting plate 9 into the arc-shaped groove 12 to connect and reinforce the two adjacent corner reinforcement plates 5;

[0092] S9: Cement construction, for filling and reinforcement.

[0093] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
