Description

Technical Field

[0001] This application relates to the field of prefabricated building equipment technology, and in particular to a BIM-based prefabricated building component. Background Technology

[0002] BIM, or Building Information Modeling, is a 3D model of a building constructed using computer terminals based on design drawings. Building upon this 3D model, BIM integrates various relevant information about the construction project into an engineering data model. It is a digital representation of the physical structure and functional characteristics of the project's facilities and is used in various aspects such as construction planning, cost control, and drawing generation. BIM is changing the way the construction industry works, making engineering projects more intelligent, efficient, and sustainable.

[0003] For prefabricated buildings that are prefabricated with BIM as the primary method, the first step is to use BIM on a computer terminal to model local components and build the overall model. This provides theoretical guidance and risk avoidance for actual construction. After the local component modeling (including prefabricated floor slabs, wall panels, steps, and structural columns) and the overall model building are completed and the construction process of the building is simulated, the construction phase can begin gradually.

[0004] During the installation of prefabricated wall panels, it is usually necessary to pre-install reinforcing bars on the building foundation. This means embedding the reinforcing bars in the foundation and using the concrete of the foundation to fix them in place. Then, the prefabricated wall panels with pre-drilled holes on the bottom are hoisted onto the foundation using hoisting equipment. This allows the reinforcing bars pre-installed on the foundation to be inserted into the prefabricated wall panels, thus completing the installation of the wall panels.

[0005] However, after the hoisting equipment lifts the wall panel above the reinforcing bars, the operator needs to constantly fine-tune the position of the wall panel so that the reinforcing bars can be inserted into the installation holes of the wall panel, which consumes a lot of wall panel installation time and reduces the installation efficiency of prefabricated wall panels. Summary of the Invention

[0006] To reduce the time consumed in installing prefabricated wall panels, this application provides a BIM-based prefabricated building component.

[0007] This application provides a BIM-based prefabricated building component, which adopts the following technical solution: A BIM-based prefabricated building component includes a limiting frame, which comprises a limiting plate one and two limiting plates two. The two limiting plates two are respectively located on both sides of the limiting plate one. Two clamping blocks for clamping reinforcing bars are arranged between the two limiting plates two. The two clamping blocks and the two limiting plates two are arranged in a one-to-one correspondence. A sliding block is slidably arranged in the limiting plate two. A connecting rod is slidably installed on the sliding block. A sliding groove for the connecting rod to slide is opened on the limiting plate two. The clamping block is installed on the connecting rod. A connecting mechanism for connecting the two clamping blocks is provided between the two clamping blocks. A driving mechanism for driving the sliding block to slide is provided in the limiting plate two.

[0008] Using the above technical solution, before the operators install the prefabricated wall panels, the limiting frame is placed in the installation position of the wall panel during the wall panel transportation and hoisting time, so that the bottom inner contour of the limiting frame coincides with the edge line of the wall panel. Then, the sliding block is driven by the drive mechanism, so that the sliding block drives the connecting rod and the clamping block to move to the position directly opposite the reinforcing steel, that is, the reinforcing steel of the building foundation is between the two clamping blocks. Next, the connecting rod is slid into the limiting frame, so that the two connecting rods drive the two clamping blocks to move closer to each other, so that the reinforcing steel is clamped by the two clamping blocks. Finally, the wall panel is hoisted into the limiting frame by the hoisting equipment, so that the outer wall of the wall panel and the inner wall of the limiting frame are in contact with each other, and the wall panel is gradually and slowly lowered from top to bottom, so that the reinforcing steel is gradually inserted into the installation holes of the wall panel, completing the installation of the wall panel.

[0009] Under the limiting effect of the limiting frame on the wall panel, and because the spacing and number of steel bars on the building foundation are highly corresponding to the spacing and number of installation holes on the wall panel, once the steel bar held by the clamping block is aligned with the accurate installation hole, the remaining steel bars and installation holes can be accurately aligned to complete the installation.

[0010] In summary, because this equipment reduces the adjustment of wall panels and the alignment of reinforcing bars, and the installation preparation work of the limiting frame can be completed in advance, the time consumed in the installation of prefabricated wall panels is reduced, thereby improving the installation efficiency of wall panels.

[0011] In a preferred embodiment, the present application may be further configured such that: the driving mechanism includes a lead screw, the lead screw is rotatably mounted within the second limiting plate, and the sliding block is threadedly connected to the lead screw.

[0012] With the above technical solution, when the operator needs to adjust the position of the clamping block, by rotating the lead screw, the lead screw drives the sliding block to move along the length direction of the second limiting plate, so that the connecting rod and the clamping block move with the sliding block, thereby completing the position adjustment of the clamping block, which can clamp steel bars with different spacings on the building foundation, thus expanding the application range of this equipment.

[0013] In a preferred embodiment, this application can be further configured as follows: a worm gear is rotatably mounted inside the limiting plate, a worm wheel is mounted on each lead screw, the worm wheel and the worm gear mesh with each other, a drive shaft is rotatably mounted on the limiting plate, a bevel gear is mounted on the worm gear, and a bevel gear is mounted on the drive shaft located inside the limiting plate, the bevel gear and the bevel gear mesh with each other.

[0014] With the above technical solution, when the operator needs to adjust the position of the clamping block, rotating the drive shaft causes the second bevel gear to rotate, which in turn drives the first bevel gear to rotate. The first bevel gear then drives the worm gear to rotate, which in turn drives the worm wheels meshing with it at both ends. Each worm wheel drives the corresponding lead screw to rotate, thereby moving the sliding block and completing the position adjustment of the clamping block. Since only rotating the drive shaft is needed to adjust the position of both clamping blocks, the operation of this equipment is simplified.

[0015] In a preferred embodiment, the present application may be further configured such that the connecting mechanism includes two sets of suction cups arranged opposite each other, the two sets of suction cups being respectively mounted on the two clamping blocks, and the suction cups arranged opposite each other being able to attract and connect with each other.

[0016] Through the above technical solution, as the two clamping blocks approach each other, the two opposing suction cups can attract each other, thus completing the connection between the two clamping blocks and reducing the possibility of the steel bars losing their restraint due to the separation of the two clamping blocks.

[0017] In a preferred embodiment, this application may be further configured such that: the clamping block has a groove for accommodating the reinforcing bar, a protective plate is installed in the groove, and each set of suction cups includes two suction cups, with the two suction cups respectively located on both sides of the groove.

[0018] Through the above technical solution, the protective plate reduces the possibility of the reinforcing bar being damaged by clamping. Furthermore, since suction cups are provided on both sides of the groove, the possibility of the clamping block rotating due to being fixed on one side by the suction cups is reduced, thus improving the stability of the clamping block in holding the reinforcing bar.

[0019] In a preferred embodiment, this application may be further configured such that: each of the second limiting plates is provided with a guide plate at its top, and each guide plate is inclined, with the guide plate inclined away from the side of the corresponding second limiting plate and towards the side away from the first limiting plate.

[0020] With the above technical solution, during the hoisting process of the wall panel, the wall panel only needs to be slowly moved to the perimeter of the limiting frame and then slowly lowered. Under the guidance of the guide plate, the wall panel can slide along the outer wall of the guide plate into the limiting frame, reducing the number of steps required for operators to align the wall panel and the limiting frame, thereby improving the installation efficiency of the prefabricated wall panel.

[0021] In a preferred embodiment, this application can be further configured such that: a plurality of bending plates are installed on the outer side of the limiting frame, the bending plates are provided with a bending part one and a bending part two, the bending part one abuts against the guide plate, the bending part two abuts against the limiting plate two, the bending plates are provided with a connector, and the bending plates are installed on the limiting plate two through the connector.

[0022] Through the above technical solution, the bending plate is installed on the limiting plate 2 through the connector. Under the support of the bending plate, the guide plate reduces the possibility of breakage at the junction of the guide plate and the limiting plate 2 due to the pressure of the wall plate on the guide plate, thereby extending the service life of the equipment.

[0023] In a preferred embodiment, the present application may be further configured such that the connector includes a bolt, and the bending plate and the limiting plate are connected by the bolt.

[0024] Using the above technical solution, the operator installs the bending plate onto the limiting plate 2 using bolt 1 to complete the installation of the bending plate, so as to support the guide plate through the bending plate.

[0025] In a preferred embodiment, this application can be further configured such that: a connecting plate is fixedly connected to the side of the connecting rod near the corresponding clamping block, and a second bolt is provided on the connecting plate, and the connecting plate and the clamping block are connected by the second bolt.

[0026] With the above technical solution, the operator can disconnect the connection between the two pairs of connecting plates and the clamping blocks by unbolting the bolts, so that the operator can replace the clamping blocks of different sizes, thus enabling the clamping of steel bars of different diameters, thereby further expanding the applicable range of this equipment.

[0027] In a preferred embodiment, this application may be further configured such that: the sliding block has an installation groove for accommodating the connecting rod, an elastic block is installed on the top inner wall of the installation groove, the elastic block is provided with an elastic protrusion for preventing the connecting rod from disengaging from the installation groove, and the thickness of the clamping block and the diameter of the connecting rod are both less than the distance from the top surface of the elastic block to the top wall of the sliding groove.

[0028] Through the above technical solution, the operator presses the connecting rod with appropriate force, causing it to overcome the elastic force of the elastic protrusion and embed itself into the installation groove. The elastic protrusion then returns to its original shape, thus limiting the connection rod and reducing the possibility of it detaching from the installation groove. Once the reinforcing bar is inserted into the wall panel's mounting hole, the connecting rod is slid outwards to separate the suction cups, allowing the connecting rod to be removed upwards from the installation groove. This facilitates the operator removing the connecting rod and clamping block from the inside of the limiting frame, reducing interference from the connecting rod and clamping block during the wall panel's descent.

[0029] In summary, this application includes the following beneficial technical effects: 1. This equipment reduces the adjustment of wall panels and the alignment of reinforcing bars, and the installation preparation work of the limit frame can be completed in advance, thus reducing the time consumed in the installation of prefabricated wall panels and improving the installation efficiency of wall panels. 2. During the hoisting process of the wall panel, the wall panel being hoisted can slide along the outer wall of the guide plate into the limiting frame under the guidance of the guide plate, which reduces the number of steps for operators to align the wall panel and the limiting frame, thereby improving the installation efficiency of the prefabricated wall panel. 3. By rotating the drive shaft, the operator can simultaneously move two clamping blocks, thereby clamping steel bars with different spacings and expanding the applicability of this equipment. Furthermore, by replacing the clamping blocks with different sizes, the operator can clamp steel bars of different diameters, further expanding the applicability of this equipment.

[0038] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail.

[0039] This application discloses a BIM-based prefabricated building component.

[0040] See attached document Figure 1 and attached Figure 2 As shown, a BIM-based prefabricated building component includes a limiting frame 1, which is horizontally positioned and has a U-shaped cross-section. The limiting frame 1 includes a limiting plate 101 and two limiting plates 102, which are located on both sides of the limiting plate 101 and are integrally formed.

[0041] See attached document Figure 1 and attached Figure 2 As shown, two clamping blocks 12 for clamping the reinforcing bars are provided between the two limiting plates 102. The clamping blocks 12 have semi-circular grooves 121 for accommodating the reinforcing bars. A protective sheet 122 made of rubber material is installed in the grooves 121. The two clamping blocks 12 and the two limiting plates 102 are arranged in a one-to-one correspondence.

[0042] Since each limiting plate 2 102 and its related structures are the same, only one limiting plate 2 102 will be described in detail below, and the other limiting plate 2 102 will not be described in detail here.

[0043] See attached document Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, each limiting plate 102 is slidably provided with a sliding block 13 along its length direction. Each sliding block 13 has an installation groove 131, in which a horizontally arranged connecting rod 2 is embedded. The limiting plate 102 has a sliding groove 14 along its length direction for the connecting rod 2 to slide. One end of the connecting rod 2 is located inside the limiting frame 1, and the other end extends out of the limiting frame 1. A clamping block 12 is installed on the end of the connecting rod 2 inside the limiting frame 1, and a handle 22 is fixedly connected to the end of the connecting rod 2 extending out of the limiting frame 1.

[0044] See attached document Figure 1 and attached Figure 2 As shown, a connecting mechanism 3 is provided between the two clamping blocks 12. The connecting mechanism 3 is used to connect the two clamping blocks 12. The connecting mechanism 3 includes two sets of suction cups 31 arranged opposite each other. The suction cups 31 arranged opposite each other can be attracted and connected. The two sets of suction cups 31 and the two clamping blocks 12 are arranged in a one-to-one correspondence. Each set of suction cups 31 includes two suction cups 31. The two suction cups 31 in the same set are fixedly connected to the side wall of one of the clamping blocks 12, and the two suction cups 31 in the same set are respectively located on both sides of the groove 121.

[0045] See attached document Figure 1 and attached Figure 2 As shown, a driving mechanism 4 is provided inside the second limiting plate 102. The driving mechanism 4 is used to drive the sliding block 13 to slide along the length direction of the second limiting plate 102. The driving mechanism 4 includes a lead screw 41 rotatably disposed on the second limiting plate 102. The length direction of the lead screw 41 is consistent with the length direction of the second limiting plate 102, and the sliding block 13 is threadedly connected to the lead screw 41.

[0046] See attached document Figure 1 and attached Figure 2As shown, a worm gear 5 is rotatably installed inside the limiting plate 101. The worm gear 5 is horizontally arranged. Each lead screw 41 has a worm wheel 411 coaxially fixedly connected to one end near the limiting plate 101. The worm wheel 411 and the worm gear 5 mesh with each other. A drive shaft 6 is rotatably installed on the limiting plate 101. One end of the drive shaft 6 extends out of the limiting plate 101, and the other end of the drive shaft 6 extends into the limiting plate 101. A bevel gear 61 is coaxially fixedly connected to the end of the drive shaft 6 that extends into the limiting plate 101. A bevel gear 51 is coaxially fixedly connected to the worm gear 5. The bevel gear 51 and the bevel gear 61 mesh with each other. A handwheel is coaxially fixedly connected to the end of the drive shaft 6 that extends out of the limiting plate 101.

[0047] Before installing the wall panel, the operator uses the transportation time of the wall panel to position the limiting frame 1, so that the bottom inner contour of the limiting frame 1 coincides with the edge line of the wall panel. Then, by turning the handwheel, the handwheel drives the clamping block 12 to move through the bevel gear 61, bevel gear 51, worm 5, worm wheel 411, lead screw 41 and connecting rod 2, until one of the steel bars on the building foundation is in the middle of the two clamping blocks 12. Next, the connecting rod 2 is pushed into the limiting frame 1, so that the clamping block 12 moves to the side closer to the steel bar, until the suction cups 31 on the different clamping blocks 12 attract each other, so that the steel bar is clamped by the clamping blocks 12. Finally, adhesive is filled into the installation hole of the wall panel, and the wall panel is transported to the top of the limiting frame 1 by the hoisting equipment, and the wall panel is slowly lowered, so that the steel bar is gradually inserted into the installation hole of the wall panel, completing the installation of the wall panel.

[0048] Under the limiting effect of the limiting frame 1 on the wall panel, and because the spacing and number of steel bars on the building foundation are highly corresponding to the spacing and number of mounting holes on the wall panel, once the steel bar clamped by the clamping block 12 is aligned with the accurate mounting hole, the remaining steel bars and mounting holes can also be accurately aligned.

[0049] In summary, this equipment reduces the need for wall panel adjustment and rebar alignment, and the pre-installation preparation of the limiting frame 1 can be completed in advance, effectively reducing the time consumed in the installation of prefabricated wall panels and thus improving the installation efficiency. Rebar installation on the building floor and wall panel construction can all be guided in advance based on BIM. Combined with the actual installation operation of this equipment, the technical advantages of BIM are fully demonstrated.

[0050] See attached document Figure 1 and attached Figure 3As shown, a connecting plate 21 is welded and fixed to the side of the connecting rod 2 near the corresponding clamping block 12. Two bolts 211 are provided on the connecting plate 21, located on opposite sides of the connecting rod 2. The connecting plate 21 and the clamping block 12 are connected by the bolts 211. By releasing the bolts 211 from the connecting plate 21 and the clamping block 12, the operator can easily replace the clamping blocks 12 with different sizes, thus enabling the clamping of steel bars of different diameters and expanding the applicability of this equipment.

[0051] See attached document Figure 1 and attached Figure 4 As shown, each limiting plate 2 102 has a guide plate 7 at its top. The length direction of the guide plate 7 is consistent with the length direction of the limiting plate 2 102. The thickness and length of the guide plate 7 are the same as those of the limiting plate 2 102. Each guide plate 7 is inclined, with the side of the guide plate 7 away from the corresponding limiting plate 2 102 tilted towards the side away from the limiting plate 1 101. During the gradual downward movement of the wall panel, if there is a certain misalignment between the wall panel and the limiting frame 1, the wall panel can slide downward along the outer wall of the guide plate 7 into the limiting frame 1 under the guidance of the guide plate 7. This reduces the number of steps required for the operator to align the wall panel and the limiting frame 1, thereby improving the installation efficiency of the prefabricated wall panel.

[0052] See attached document Figure 1 and attached Figure 4 As shown, several bent plates 71 are installed on the outer side of the limiting frame 1. The longitudinal section of the bent plate 71 is "L" shaped. The bent plate 71 is provided with a first bent part 711 and a second bent part 712. The first bent part 711 and the second bent part 712 are integrally formed. The first bent part 711 abuts against the guide plate 7, and the second bent part 712 abuts against the limiting plate 102. Under the support of the bent plates 71, the possibility of the guide plate 7 breaking at the junction of the guide plate 7 and the limiting plate 102 due to the pressure of the wall panel on the guide plate 7 is reduced. A connector 8 is provided on the bent plate 71. The connector 8 includes a first bolt 81. The bent plate 71 and the limiting plate 102 are connected by the first bolt 81. The guide plate 7 and the bent plate 71 are also connected by the first bolt 81.

[0053] See attached document Figure 3 Appendix Figure 5 and appendix Figure 6As shown, the longitudinal section of the mounting groove 131 is V-shaped. Elastic blocks 9 are fixedly connected to the inner walls of the top of both sides of the mounting groove 131. Each elastic block 9 has an elastic protrusion 91 on the side near the connecting rod 2. The elastic protrusion 91 prevents the connecting rod 2 from detaching from the mounting groove 131. By pressing the connecting rod 2, the operator overcomes the elastic force of the elastic protrusion 91 and embeds it into the mounting groove 131. Afterward, the elastic protrusion 91 returns to its original shape, thus limiting the connection rod 2 and reducing the possibility of it detaching from the mounting groove 131.

[0054] See attached document Figure 5 and attached Figure 6 As shown, the thickness of the clamping block 12 and the diameter of the connecting rod 2 are both less than the distance from the top surface of the elastic block 9 to the top wall of the sliding groove 14. Therefore, after the reinforcing bar has been inserted into the mounting hole of the wall panel, the operator can forcefully pull the connecting rod 2 outward to separate the suction cups 31 from each other and remove the connecting rod 2 upward from the mounting groove 131. This allows the operator to remove the connecting rod 2 and the clamping block 12 from the inside of the limiting frame 1, thereby reducing the interference caused by the connecting rod 2 and the clamping block 12 to the descent of the wall panel.

[0055] The implementation principle of this embodiment is as follows: Before the operator installs the prefabricated wall panel, the positioning frame 1 is positioned using the manufacturing and transportation time of the wall panel, so that the bottom inner contour of the positioning frame 1 coincides with the edge line of the wall panel. Then, by rotating the handwheel, the clamping block 12 is moved so that one of the steel bars is in the middle of the two clamping blocks 12. Next, the connecting rod 2 is slid into the positioning frame 1 to clamp the steel bar on the building foundation through the clamping blocks 12. Finally, adhesive is filled into the installation hole of the wall panel, and the wall panel is moved above the positioning frame 1 by hoisting equipment, and the wall panel is slowly lowered so that the steel bar is gradually inserted into the installation hole of the wall panel, completing the installation of the wall panel.

[0056] Because this equipment reduces the adjustment of wall panels and the alignment of reinforcing bars, and the installation preparation work of the limiting frame 1 can be completed in advance, it effectively reduces the time consumed in the installation of prefabricated wall panels, thereby improving the installation efficiency of wall panels.

[0057] The embodiments described in this specific implementation are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
