Description

Technical Field

[0001] This application relates to the technical field of prefabricated buildings, and particularly to a prefabricated building based on BIM technology. Background Art

[0002] Building Information Modeling, abbreviated as BIM, is a brand-new building information modeling technology that integrates all the information involved in the whole process of building project design, construction, and operation management into a single, complete digital information model. The application of BIM technology in prefabricated buildings is mainly reflected in its integrated support for the whole process of design, production, construction, decoration, and management, such as the composition of doors, walls, assembly plates, etc.

[0003] The existing Chinese invention patent document with the publication number CN114412206B discloses a prefabricated building based on BIM technology, including a base, as well as a first structural support member and a second structural support member. The first structural support member and the second structural support member are symmetrically arranged, and the distance between the output ends of the two is greater than the distance between their fixed ends. This structure achieves the purpose of reliably fixing and conveniently adjusting precast components, and solves the problems of low construction efficiency and cumbersome processes in the traditional method.

[0004] In the above solution, an instrument is needed to measure the perpendicularity of the component, and then the first structural support member and the second structural support member are used for connection. The operation is relatively cumbersome, and it is not easy to keep the precast component in a vertical state during the connection process. Therefore, there is still room for improvement. Summary of the Invention

[0005] This application provides a prefabricated building based on BIM technology.

[0006] This application adopts the following technical solutions: A prefabricated building based on BIM technology includes a structural main body and precast components, and further includes a positioning plate arranged on the side wall of the precast component and a connecting component for connecting the positioning plate and the structural main body. The positioning plate is perpendicular to the surface of the precast component; the connecting component includes a base arranged on the surface of the structural main body, a lifting seat slidably arranged vertically on the base, a first elastic member arranged between the base and the lifting seat, and a locking member arranged on the lifting seat for connecting with the positioning plate. The surface of the lifting seat is horizontally arranged, and a positioning member for positioning the abutting seat is arranged on the base; The locking member includes a sliding seat slidably disposed on the side wall of the lifting seat and an abutting seat disposed on the sliding seat. The lifting seat is provided with a sliding groove for the sliding seat to slide; a space for inserting the positioning plate is formed between the abutting seat and the sliding seat. When the positioning plate abuts and fits on the surface of the lifting seat, sliding the sliding seat can make the abutting seat abut on the surface of the positioning plate. An inclined support is connected between the precast member and the structural body.

[0007] By adopting the above technical solution, when the precast member is installed on the structural body, the positioning plate abuts on the surface of the abutting seat. When the positioning plate and the surface of the abutting seat are in contact, the precast member is in a vertical state. Then, the positioning plate and the abutting seat are connected together by the locking member, and the abutting seat is positioned by the positioning member, so that the precast member is in a vertical state. Finally, the precast member is further reinforced by the inclined support.

[0008] Optionally, a rotating column is rotatably disposed on the side wall of the abutting seat. One end of the rotating column away from the abutting seat is threadedly connected with a screw rod. A positioning groove is formed on the side wall of the sliding seat. When the abutting seat abuts on the positioning plate, rotating the rotating column makes the screw rod corresponding to the position of the positioning groove and can pass through the lifting seat and be inserted into the positioning groove.

[0009] By adopting the above technical solution, after the positioning plate and the abutting seat are connected together, the screw rod passes through the abutting seat and is inserted into the positioning groove, thereby further positioning the sliding seat and the abutting seat and improving the stability of the structure.

[0010] Optionally, a reinforcing plate is disposed on the positioning plate. A relief groove for accommodating the reinforcing plate is formed on the abutting seat; a connecting member capable of connecting with the reinforcing plate is disposed on the abutting seat.

[0011] By adopting the above technical solution, the abutting seat and the reinforcing plate are connected together by the connecting member, improving the stability of the abutting seat.

[0012] Optionally, an installation hole is formed on the side wall of the abutting seat, and the installation hole penetrates through to the relief groove. A rotating shaft is disposed on the rotating column, and the rotating shaft is rotatably connected in the installation hole. The connecting member includes a connecting rod slidably disposed in the installation hole and a second elastic member disposed between the connecting rod and the inner wall of the installation hole. A slot for inserting the connecting rod is formed on the reinforcing plate; when the rotating shaft rotates, the connecting rod can be driven to slide and be inserted into the slot, and the second elastic member provides a restoring force for the connecting rod.

[0013] By adopting the above technical solution, when the rotating shaft rotates, it pushes the connecting rod to slide and insert into the slot, thereby connecting the abutting seat and the reinforcing plate together.

[0014] Optionally, an arc-shaped protrusion is provided at one end of the rotating shaft close to the connecting rod, and a contact seat is provided at one end of the connecting rod close to the rotating shaft. When the rotating shaft rotates, the arc-shaped protrusion can abut against the contact seat and push the connecting rod to slide.

[0015] By adopting the above technical solution, when the rotating shaft rotates, the arc-shaped protrusion abuts against the contact seat, thereby pushing the connecting rod to slide.

[0016] Optionally, a sliding column is slidably arranged on the surface of the sliding seat, and a limiting groove for inserting the sliding column is provided on the inner wall of the sliding groove; a triggering member is arranged in the sliding seat. When the screw rod is inserted into the positioning groove, the sliding column can be driven by the triggering member to insert into the limiting groove.

[0017] By adopting the above technical solution, when the screw rod is inserted into the positioning groove, the sliding column is driven by the triggering member to insert into the limiting groove, further improving the connection stability between the sliding seat and the lifting seat.

Detailed Description of the Embodiment

[0027] The following further describes the present application in detail with reference to the drawings.

[0028] An embodiment of the present application discloses a prefabricated building based on BIM technology. Refer to Figure 1 , the prefabricated building includes a structural main body 1 and prefabricated components 2 installed on the structural main body 1, and further includes a positioning plate 3 installed on one side wall of the prefabricated component 2 and a connecting component 4. The positioning plate 3 is an L-shaped structure, and the horizontal part of the positioning plate 3 is vertically arranged on the surface of the prefabricated component 2 and is provided with a plurality of them along the horizontal direction. In this embodiment, 3 are used for illustration. The connecting component 4 corresponds to the positioning plate 3, and 3 are also correspondingly provided.

[0029] Refer to Figure 1 and Figure 2 , the connecting component 4 includes a base 41 installed on the surface of the structural main body 1, a lifting seat 42 slidably arranged on the base 41, a first elastic member 43 installed between the lifting seat 42 and the base 41, and a locking member 44 installed on the lifting seat 42. The surface of the lifting seat 42 is horizontally arranged, a column 23 is fixed at the lower end of the lifting seat 42, and a slot 24 for the column 23 to slide is opened on the base 41. The first elastic member 43 is a spring and is installed between the bottom of the slot 24 and the lower end of the column 23. When installing the prefabricated component 2, the positioning plate 3 can abut against the lifting seat 42 and squeeze the lifting seat 42 to move downward, and adjust the prefabricated component 2 until the positioning plate 3 fits on the surface of the lifting seat 42. A positioning member 5 is installed on the base 41, and the positioning member 5 is a second bolt threadedly connected to the side wall of the base 41. When the prefabricated component 2 is in a vertical state, the second bolt abuts against the column 23 to position the column 23.

[0030] An extension block 25 is fixed at the lower end of the side wall of the base 41. A first bolt 27 passes through the extension block 25, and a waist-shaped slot 26 is opened on the extension block 25. The first bolt 27 passes through the waist-shaped slot 26 and is connected to the structural main body 1, so that the base 41 can be adjusted in a certain direction along the waist-shaped slot 26 to make the lifting seat 42 correspond to the positioning plate 3.

[0031] Refer to Figure 2 and Figure 3 , a chute 6 is opened on the side of the lifting seat 42 facing away from the prefabricated component 2. The locking member 44 includes a sliding seat 441 slidably inserted into the chute 6 and an abutting seat 442 installed on the sliding seat 441. There is a gap between the abutting seat 442 and the sliding seat 441. When the positioning plate 3 abuts against the upper surface of the lifting seat 42, the sliding seat 441 is inserted into the chute 6, and the abutting seat 442 abuts against the surface of the positioning plate 3, so that the prefabricated component 2 is not easily displaced again and remains in a vertical state. At this time, the positioning plate 3 fits on the surface of the lifting seat 42, and the abutting seat 442 fits on the surface of the positioning plate 3. Then, a plurality of diagonal braces 30 are connected between the prefabricated component 2 and the structural main body 1 by welding.

[0032] Refer toFigure 4 and Figure 5 Rotating posts 7 are rotatably mounted on the outer walls of both sides of the end of the abutting seat 442 near the prefabricated component 2, and a screw 8 is threadedly connected to one end of the rotating post 7. Positioning slots 9 are defined on the side walls of the sliding seat 441. When the sliding seat 441 is inserted into the chute 6, the rotating posts 7 are rotated to a vertical position. Through holes 29 are defined on the side walls of the lifting seat 42 at positions corresponding to the positioning slots 9. The screw 8 can pass through the through holes 29 and be inserted into the positioning slots 9, thereby preventing the sliding seat 441 from sliding out of the chute 6.

[0033] In a further embodiment, referring to Figure 3 and Figure 4 A reinforcing plate 10 is fixed to the positioning plate 3. The reinforcing plate 10 has a triangular structure. A clearance groove 11 is formed on the abutment seat 442. When the abutment seat 442 abuts the surface of the positioning plate 3, the clearance groove 11 abuts the clearance groove 11. A connecting member 12 is also installed on the abutment seat 442. When the rotating column 7 rotates to allow the screw 8 to be inserted into the positioning groove 9, the connecting member 12 can be synchronously driven to connect the abutment seat 442 and the reinforcing plate 10 together.

[0034] The sidewall of the abutment seat 442 is provided with a mounting hole 13, which extends through the clearance groove 11. A rotating shaft 14 is fixed to the rotating column 7 and is rotatably connected to the mounting hole 13 via a bearing or other means. The connecting member 12 includes a connecting rod 121 that is slidably mounted in the mounting hole 13, and a second elastic member 122 that is connected between the sidewall of the connecting rod 121 and the inner wall of the mounting hole 13. The second elastic member 122 is a spring and is sleeved on the outer wall of the connecting rod 121. The inner wall of the mounting hole 13 provides a space for installing the second elastic member 122. To facilitate installation, the abutment seat 442 can be a spliced structure. A slot 15 is provided on the reinforcement plate 10 at a position corresponding to the mounting hole 13. When the rotating shaft 14 rotates, the rotating shaft 14 can push the connecting rod 121 into the slot 15. At this time, the second elastic member 122 is in a stretched state, providing a force for the connecting rod 121 to slide back into the mounting hole 13.

[0035] An arc-shaped protrusion 16 is fixed to one end of the rotating shaft 14, and two arc-shaped protrusions 16 are symmetrically arranged. Two abutment seats 17 are fixed to the end of the connecting rod 121 close to the rotating shaft 14, and the edges of the abutment seats 17 are in an arc-shaped structure. When the rotating shaft 14 rotates, the arc-shaped protrusion 16 can abut against the abutment seats 17 and push the connecting rod 121 to slide, so that the connecting rod 121 is inserted into the slot 15. In order to limit the sliding of the connecting rod 121 in the mounting hole 13, a guide groove and a guide block can be provided between the connecting rod 121 and the inner wall of the mounting hole 13 (not shown in the figure). In other embodiments, the connecting rod 121 can be provided as a square rod structure, and the position of the mounting hole 13 corresponding to the connecting rod 121 is a shape that is compatible with the connecting rod 121.

[0036] Reference Figure 5 and Figure 6 The upper surface of the sliding seat 441 is provided with a sliding column 18 that slides up and down. The sliding column 18 is located in the middle of the sliding seat 441 and is provided with two. Figure 7 The inner top surface of the sliding groove is provided with a limit groove 19, which corresponds to the sliding post 18. A trigger member 20 is mounted on the sliding seat 441. When the screw 8 is inserted into the positioning groove 9, the trigger member 20 can drive the sliding post 18 to slide upward and insert into the limit groove 19.

[0037] Reference Figure 4 and Figure 7 The sliding seat 441 is provided with a receiving slot 21, into which the sliding post 18 is slidably mounted. The sliding seat 441 is provided with a mounting slot 22, which extends radially along the positioning slot 9 and connects the positioning slot 9 with the receiving slot 21. The trigger member 20 includes a trigger rod 201 that is slidably inserted into the mounting slot 22, and a third elastic member 202 mounted on the outer wall of the trigger rod 201. The third elastic member 202 is a spring, and the mounting slot 22 provides space for the elastic member to be installed. For ease of installation, the sliding seat 441 can be a structure that is spliced in half. Under the action of the third elastic member 202, one end of the trigger rod 201 extends into the positioning slot 9. A fourth elastic member 28 is mounted between the inner wall of the receiving slot 21 and the sliding post 18. The fourth elastic member 28 is a spring. Both ends of the trigger rod 201 have an arc-shaped structure, and the lower end of the sliding post 18 also has an arc-shaped structure. In the natural state, the lower end of the sliding post 18 abuts the end of the trigger rod 201. When the screw rod 8 is inserted into the positioning groove 9, the screw rod 8 presses against the trigger rod 201 and pushes the trigger rod 201 to slide toward the sliding post 18. The trigger rod 201 then drives the sliding post 18 to slide upward and insert into the limiting groove 19. When the screw rod 8 disengages from the positioning groove 9, the third elastic member 202 drives the trigger rod 201 to return to its original position, and the sliding post 18 slides downward again into the receiving groove 21.

[0038] The implementation principle of a prefabricated building based on BIM technology in the embodiment of the present application is as follows: the prefabricated component 2 is adjusted so that the surfaces of the positioning plate 3 and the lifting seat 42 abut against each other, so that the prefabricated component 2 is in a vertical state, and then the positioning plate 3 and the lifting seat 42 are connected together by the locking member 44, and the column 23 is positioned by the second bolt. Finally, the inclined support 30 can be used to further reinforce the connection between the prefabricated component 2 and the structural body 1. After the prefabricated component 2 and the structural body 1 are connected to the outer wall and the cast part solidifies, the connecting assembly 4 and the positioning plate 3 can be removed.

[0039] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application.
