Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a green building component for prefabricated building design based on BIM. Background Art

[0002] In the field of modern construction, prefabricated buildings, as a new type of construction method, have been widely used due to their high efficiency and environmental protection. Prefabricated buildings prefabricate building components in factories and then assemble them on site, which greatly shortens the construction period and reduces the environmental impact of on-site construction. However, with the increasing demand for diversified architectural design, the existing prefabricated building component system has exposed some limitations, especially in the connection method between components.

[0003] At present, common prefabricated building components mainly adopt standardized right-angle connection design. This design has good stability and ease of operation during construction and is suitable for most traditional building structures. However, when faced with complex building structures or innovative designs that require inclined splicing, the limitations of right-angle connections begin to emerge. Since prefabricated components are mainly designed with right-angle connections in mind, in actual applications, the splicing angles between components cannot be flexibly adjusted, which cannot meet the architects' design requirements for achieving inclined splicing and non-standard angle splicing.

[0004] This technical problem not only limits the freedom of architectural design, but also leads to compromises in architectural aesthetics and functionality in some cases. In addition, in order to achieve tilted splicing, the construction party often needs to make additional adjustments or processing on site, which increases the complexity and cost of construction. Therefore, the development of a prefabricated building component that can support tilted splicing has become a key technical challenge that needs to be urgently solved in the current field of prefabricated buildings. This new component will help improve the flexibility and diversity of architectural design while maintaining the efficiency and environmental protection characteristics of prefabricated buildings. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a green building component for BIM-based prefabricated building design, which solves the problem that the existing prefabricated building components cannot be spliced ​​at an angle.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a green building component for BIM-based prefabricated building design, including a prefabricated tube that provides a basic connection and a wall panel assembled therewith, the top and bottom of the prefabricated tube are fixedly connected with a connecting seat, and an annular steel bar hoop for providing a connecting position is installed on the outside of the prefabricated tube, a plurality of groups of plug holes are provided in the middle of the connecting seat, and a docking hole corresponding to the position of the plug hole is provided at the end of the wall panel, and a positioning steel bar is passed between the plug hole and the docking hole.

[0007] Preferably, a partition for dividing the space is fixedly installed inside the wall panel, and the partition divides the internal space of the wall panel into two parts: an open cavity and a closed cavity.

[0008] Preferably, a connection groove matching the size and position of the annular steel bar hoop is provided at the end of the wall panel to facilitate the entry of the entire wall panel.

[0009] Preferably, an arc-shaped notch matched with the size of the prefabricated tube is opened at the end of the wall panel, and the curvature of the arc-shaped notch corresponds to the curvature of the prefabricated tube.

[0010] Preferably, a second plugging hole is provided on the periphery of the connection seat, and a second docking hole corresponding to the position of the second plugging hole is provided on the end of the wall panel.

[0011] Preferably, the annular steel bar hoop and its mounting portion are offset from the positions of the first and second insertion holes to ensure effective insertion of the positioning steel bars.

[0012] Preferably, a pouring port 1 is provided on the top of the connecting seat, and the pouring port 1 is communicated with the inner cavity of the prefabricated tube.

[0013] Preferably, a step groove is opened on the outer side of the connecting seat, a casting template is installed on the outer side of the connecting seat through connecting bolts, and the casting template is installed at the position of the step groove.

[0014] Preferably, the open cavity is communicated with the space enclosed by the plurality of casting templates, and a second casting port is provided on the top of the wall panel, and the second casting port is communicated with the open cavity.

[0015] Preferably, the number and position of the docking hole 1 and the plug-in hole 1 and the position of the mounting portion of the annular steel bar hoop are adapted to the angle of the components to be spliced.

[0016] Working principle: first install the prefabricated tube at the prefabrication position, then lift the wall panel as a whole through the hoist, align the connecting groove and the annular steel bar hoop, then move the wall panel along the connecting groove between the two prefabricated tubes, first preliminarily fix the wall panel, and then insert the positioning steel bars from the positions of plug hole one and plug hole two. After passing through the pouring mouth two and plug hole two, the positioning steel bars pass through the middle of docking hole one and docking hole two, and pass through the middle of the annular steel bar hoop, and then pass through the plug hole one and plug hole two at the bottom, thereby completing the connection between the prefabricated tube and the wall panel, and then tie the positioning steel bars and the annular steel bar hoop on the outside for subsequent pouring operations. When splicing, the docking hole 1 corresponding to the plug-in hole 1 and the docking hole 2 corresponding to the plug-in hole 2 can be adjusted as needed, so as to change the splicing angle of the two wall panels. Then, after the wall panel and the prefabricated tube are spliced, the casting template is installed at the step groove position through the connecting bolts, thereby sealing and blocking the open part on the outside of the prefabricated tube. Then, concrete slurry is injected from the pouring port 1 and the pouring port 2 to fill the open cavity, the internal cavity of the prefabricated tube, and the space enclosed by the prefabricated tube and the casting template with concrete. After solidification is completed, the wall panel and the prefabricated tube can be completely assembled, thereby improving the structural strength after assembly and greatly improving the construction efficiency.

[0017] The present invention provides a green building component for BIM-based prefabricated building design, which has the following beneficial effects: 1. The present invention provides a plurality of groups of plug-in holes 1 and 2 in the middle of the connection seat, and provides matching docking holes 1 and 2 at corresponding positions of the ends of the wall panels. Thus, the connection position of the wall panel and the prefabricated tube can be changed according to the installation requirements between the two wall panels, thereby realizing the angled splicing between the two wall panels, which greatly improves its practicality.

[0018] 2. The present invention opens an open cavity at the end of the wall panel, and installs multiple casting templates outside the connecting seat through connecting bolts, connects the open cavity and the space enclosed by the casting template, and then pours concrete through the second casting port. After the concrete solidifies, the connection of the wall panel, prefabricated tube, annular steel hoop, positioning steel bar and other structures can be completed, thereby improving the structural strength of the prefabricated building and improving the construction efficiency.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example: Please see attached Figure 1 -Attached Figure 4 , an embodiment of the present invention provides a green building component for BIM-based prefabricated building design, including a prefabricated tube 2 that provides a foundation connection and a wall panel 1 assembled therewith. During the construction process, the prefabricated tube 2 is first preinstalled at a specific position to ensure the accuracy of its position and verticality, and the stability of the prefabricated tube 2 is ensured by necessary reinforcement measures. Thereafter, the prefabricated wall panel 1 is inserted from the side of the prefabricated tube 2 to connect the wall panel 1 to the prefabricated tube 2. Through this construction method of pre-installing the prefabricated tube 2 first and then assembling the wall panel 1, the efficiency and accuracy of on-site construction are significantly improved, the manpower and time costs are effectively reduced, and the impact on the environment during the construction process is reduced, so that such green building components have a wider applicability in various construction projects.

[0023] The internal structural design of the wall panel 1 fully considers the rationality of material use and the balance of structural strength. Inside the wall panel 1, a partition 12 for space division is fixedly installed, and the partition 12 divides the internal space of the wall panel 1 into two parts: an open cavity 13 and a closed cavity 11. The existence of the partition 12 not only effectively enhances the overall structural strength of the wall panel 1, but also reduces unnecessary material consumption by optimizing the use of materials, thereby reducing production costs. In addition, the design of the open cavity 13 makes it possible to further enhance the stability and firmness of the connection by pouring concrete after the wall panel 1 is connected to the prefabricated tube 2. In the process of pouring concrete in the open cavity 13, the concrete can form an integrated structure with the connection part of the prefabricated tube 2, thereby greatly improving the overall performance of the entire component and ensuring that it can remain stable during long-term use.

[0024] See attached Figure 2 -Attached Figure 6 , the top and bottom of the prefabricated tube 2 are fixedly connected with a connection seat 3, and the outer side of the prefabricated tube 2 is installed with a ring steel hoop 21 to provide a positioning reference for connection with the wall panel 1. The end of the wall panel 1 is provided with a connection groove 16 that matches the size and position of the ring steel hoop 21. This design not only ensures that the wall panel 1 can be accurately inserted between the prefabricated tubes 2, but also greatly simplifies the installation process. After the prefabricated tube 2 is installed as a whole, the wall panel 1 is lifted to a suitable height by the hoisting equipment, and the connection groove 16 on the side of the wall panel 1 is aligned with the ring steel hoop 21 on the prefabricated tube 2. In this process, the construction personnel only need to pull the wall panel 1 horizontally to accurately pull it between the two prefabricated tubes 2 to complete the tight connection between the wall panel 1 and the prefabricated tube 2. This operation method ensures that the connection between the wall panel 1 and the prefabricated tube 2 is tight and firm, thereby significantly improving the seismic resistance and service life of the wall structure, and is particularly suitable for high-rise buildings and complex building environments.

[0025] In addition, an arc-shaped notch 15 matching the size of the prefabricated tube 2 is designed at the end of the wall panel 1. The curvature of the arc-shaped notch 15 corresponds to the curvature of the prefabricated tube 2, ensuring that the wall panel 1 can rotate along the circular surface of the prefabricated tube 2 during installation. Through this design, the wall panel 1 can not only adjust the angle more flexibly during installation, but also adapt to different architectural design requirements and realize more complex and diversified architectural structures. This flexibility of the wall panel 1 enables it to cope with the challenges of various installation angles in practical applications, ensuring that the installation can be completed smoothly under any circumstances and maintaining a high level of structural stability.

[0026] There are multiple groups of plug holes 4 evenly distributed in the middle of the connection seat 3. These plug holes 4 are distributed in a circle along the center position of the prefabricated tube 2, so that the wall panel 1 can find the corresponding connection point no matter from which angle it is spliced ​​with the prefabricated tube 2. The end of the wall panel 1 is also correspondingly provided with a docking hole 17 corresponding to the position of the plug hole 4. This design not only enhances the stability of the entire structure, but also greatly facilitates the installation and connection of multiple wall panels 1 during the construction process. Especially when multiple wall panels 1 need to be spliced ​​at different angles, this multi-point connection method can effectively ensure the close fit between the wall panels 1, improve the overall stability and seismic performance of the building, and is suitable for various stringent architectural structure design requirements.

[0027] See attached Figure 5 and attached Figure 6 , the outer periphery of the connection seat 3 is also provided with a plug hole 2 5, and the end of the wall panel 1 is correspondingly provided with a docking hole 2 18 corresponding to the position of the plug hole 2 5. Positioning steel bars 7 are inserted between the plug hole 1 4 and the docking hole 17, and between the docking hole 2 18 and the plug hole 2 5. After the wall panel 1 is hoisted between the two prefabricated tubes 2, the construction personnel manually adjust the holes of the plug hole 1 4 and the docking hole 17 to accurately align them, and then insert the positioning steel bar 7 from the plug hole 1 4, and the positioning steel bar 7 passes through the docking hole 17 and the plug hole 1 4 at the bottom into the prefabricated tube 2 and passes out again to complete the firm connection between the wall panel 1 and the prefabricated tube 2. When vertical angle installation is required, the construction personnel only need to insert the positioning steel bar 7 between the docking hole 17 and the plug hole 1 4 to ensure the connection strength between the wall panel 1 and the prefabricated tube 2. At the same time, the setting of the plug hole 2 5 not only provides convenience for the subsequent template installation, but also provides a reliable fixed reference during the concrete pouring process. When the wall panel 1 is installed to the right angle edge of the connection seat 3 of the prefabricated tube 2, if the installation angle of the two wall panels 1 is not a right angle, additional positioning steel bars 7 can be inserted through the positions of the plug hole 2 5 and the docking hole 2 18, so as to further enhance the installation stability of the wall panel 1 and the structural strength of the entire building. The number and position of the docking hole 17 and the plug hole 1 4, as well as the installation position of the annular steel bar hoop 21, are precisely designed according to the angle of the components to be spliced, ensuring that the wall panel 1 and the prefabricated tube 2 can achieve accurate and stable connection at any angle.

[0028] See attached Figure 2 -Attached Figure 6, the annular steel bar hoop 21 and its installation position are precisely staggered with the positions of the plug hole 1 4 and the plug hole 2 5 to ensure that the positioning steel bar 7 can be inserted smoothly and avoid being blocked during the insertion process. This careful staggered design not only ensures smooth connection during the construction process, but also effectively improves the installation efficiency and reduces construction delays caused by obstruction of steel bar insertion. A pouring port 6 is provided on the top of the connecting seat 3, and the pouring port 6 is connected to the inner cavity of the precast tube 2. After completing the connection between the wall panel 1 and the precast tube 2, the construction personnel can pour concrete into the inside of the precast tube 2 through the pouring port 6. This practice further improves the overall strength of the precast tube 2, while ensuring that the entire building component can withstand greater external loads, improving the overall compression and shear resistance of the building, and meeting the structural requirements of high-strength buildings.

[0029] Refer to the attached Figure 3 and attached Figure 5 , a step groove 31 is provided on the outside of the connection seat 3, and a casting template 32 is installed on the outside of the connection seat 3 through a connecting bolt 33, and the casting template 32 is precisely installed at the position of the step groove 31. When the wall panel 1 and the prefabricated tube 2 are spliced, a certain angle will be formed between the wall panel 1 and the connection seat 3. At this time, the casting template 32 can be firmly installed at the position of the step groove 31 through the connecting bolt 33, thereby providing template support for subsequent concrete pouring. The open cavity 13 is connected to the space surrounded by multiple casting templates 32, and a second casting port 14 is also provided on the top of the wall panel 1, and the second casting port 14 is connected to the open cavity 13. After the installation of the casting template 32 is completed, the construction personnel can pour concrete into the open cavity 13 through the second casting port 14, and the concrete will enter the space surrounded by the casting template 32 through the open cavity 13. After the concrete is completely solidified, the connection between the wall panel 1 and the prefabricated tube 2 will be tighter and firmer, and the integrity and strength of the entire structure will be greatly improved. Through this comprehensive pouring of concrete, the strength of the building components has been further enhanced, which can effectively cope with various complex external loads and natural disasters. At the same time, the poured structure not only has high strength characteristics in the short term, but also shows excellent durability and stability in long-term use, further ensuring the safety and service life of the building.
