Description

Technical Field

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

[0002] In the field of architectural decoration, traditional building component installation methods are mainly suitable for regular planar structures. However, with the increasing demands for aesthetics and uniqueness in architecture, the demand for curved walls or irregularly shaped decorative panels is growing. Traditional building components often struggle to meet the decorative needs of curved walls or irregular shapes. Some special architectural designs require decorative effects that are discontinuous, loosely joined, and with angles that are not perfectly flat, in order to create a unique visual experience. However, the market currently lacks prefabricated building components and installation methods that can effectively achieve such special decorative effects. For the decorative needs of curved walls or irregular shapes, traditional panel filling methods are difficult to install precisely, failing to meet the requirements of modern architecture for personalization and aesthetics.

[0003] Chinese utility model patent with announcement number CN209742289U discloses a BIM-based energy-saving exterior wall insulation and decorative panel. The insulation and decorative panel includes connecting components, insulation board components, and decorative board components. This solution is a traditional building component that can only complete the installation on a flat wall surface.

[0004] Chinese invention patent CN118531937A discloses a curved curtain wall support device, comprising: a building exterior wall; and two connecting structures, each fixed to one side of the building exterior wall by washers and bolts. Adjacent sides of the two connecting structures are also fixedly connected to support blocks by washers and bolts. Connecting blocks are installed inside the movable opening via two connecting bolts. An installation block is fixedly connected to the other end of each connecting block. Rotation openings are provided on the other side of the installation block at both the top and bottom positions. This invention provides a curved curtain wall support structure that allows for timely adjustment of the angle of the connecting blocks or the angle of the installation rods to adjust the position of the support plate if deviations occur at the connection points during the installation of the curved curtain wall. This avoids increased installation difficulty due to misalignment at the connection points caused by the irregular shape of the curved curtain wall, thus reducing the risk of installing curved curtain walls on building exterior walls.

[0005] In this proposed solution, each curved curtain wall panel requires a support device for one-to-one connection with the wall surface, necessitating multiple drilling processes. This results in a complex installation structure and low installation efficiency. Furthermore, the existing curved curtain wall technology offers a fixed viewing angle, making multi-angle installation impossible with current supporting building components. It also requires a certain degree of flatness in the wall surface, hindering installation under special conditions such as gradual changes in curtain wall or panel angles.

[0006] In addition, when installing decorative panels on curved walls or irregular shapes using existing technologies, the lack of precise installation guidance means that the construction process often relies on the experience of workers, making it difficult to guarantee installation accuracy and prone to errors, which affects the final decorative effect.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 , 2 As shown in Embodiment 1, a BIM-based prefabricated building component includes a metal mesh 2 for fitting against a wall. Several wall-mounted supports 3 are provided on the wall surface, and each wall-mounted support 3 has a locking structure at its outer end for fixing the metal mesh 2. By providing several wall-mounted supports on the wall surface, an installation base is provided for the metal mesh. The locking structure allows for convenient connection with the metal mesh, thus utilizing the flexibility of the metal mesh to adapt to the curvature requirements of the wall surface, forming an installation base that matches the curvature of the wall surface to meet installation needs under different conditions. Several adjustable connectors 4 are provided on the metal mesh, and these adjustable connectors 4 are connected to a decorative panel 5. Further provision of adjustable connectors enables adjustable connection between the decorative panel and the metal mesh, meeting the installation angle and fixing requirements of the panel.

[0026] Specifically, in this embodiment, the wall mounting base 3 includes a T-shaped base 31, which is fixedly connected to the wall by expansion bolts. A locking structure is located at the end of the T-shaped base 31. In this embodiment, setting the wall mounting base in a T-shape allows for a certain gap between the metal mesh and the wall, avoiding interference with the installation of the decorative panel. As a further effect, the gap between the decorative panel and the wall can be used to form an air layer, using the decorative panel to block light and prevent excessive heat from direct sunlight on the wall in summer, thus providing a certain sunshade effect.

[0027] In practical application, to improve installation accuracy and the rationality of the actual installation layout, this embodiment first utilizes BIM software to model the location and angle of the building components to be installed on the curved building surface. This allows for the simulation and planning of the required number, installation location, and dimensions of the building components, improving accuracy and installation efficiency during actual construction. Subsequently, based on BIM or design information, a corresponding number of wall-mounted brackets are installed at the corresponding positions on the wall. The metal mesh is then connected and fixed using the connecting structure of the wall-mounted brackets, forming an installation base that matches the shape of the wall. Finally, the decorative panels are fixed to the metal mesh using adjustable connectors. During the fixing process, the tilt angle of the decorative panels is adjusted according to the design to meet the installation requirements. This building component installation structure is simple and reliable, and the installation process is simple and efficient, well-suited for the assembly and installation of decorative panels on curved walls.

[0028] Example 2, based on Example 1, such as Figure 3As shown, the locking structure includes a chassis 32 rotatably mounted on the end of a T-shaped base 31. The chassis 32 has several uprights 33, forming a cross-shaped receiving groove between them. The metal mesh 2 passes through the receiving groove. Each upright 33 is inserted into a cover plate 35, and each upright 33 has a nut at its end for locking the cover plate 35. Specifically, in this embodiment, four uprights are arranged in a rectangular pattern. The cross-shaped receiving groove of the trolley is used to engage with the cross intersection of the metal mesh, thus limiting the position of the metal mesh. The cover plate has insertion holes for engaging with the four uprights, and the outer ends of the uprights have external threads. The cover plate is used to press the metal mesh placed in the receiving groove, and the nuts on the uprights are used to lock it in place. The rotatable engagement between the chassis and the T-shaped base facilitates fine-tuning of the angle during installation, adapting to the actual installation angle requirements of the metal mesh, making the structure more reliable.

[0029] Example 3, based on Example 2, such as Figure 4 , 5 As shown, the adjustable connector 4 includes a clamp connected to the metal mesh 2. The clamp is connected to one end of an adjusting rod 41, and the other end of the adjusting rod 41 is connected to a connecting seat 42. The decorative panel 5 is connected to the connecting seat 42. In this embodiment, the metal mesh 2 is a mesh-like steel wire rope mesh. The mesh of the mesh-like steel wire rope mesh is rectangular or rhomboid. The mesh-like steel wire rope mesh is made of steel wire rope and has a certain degree of flexibility, which can better match the shape of the wall. Four adjusting rods are hinged to each connecting seat and connected to the metal mesh through four frames.

[0030] Specifically, the clamp includes a fixing part 44, which is hinged to a clamping part 45. A locking bolt 46 is fitted between the fixing part 44 and the clamping part 45. An arc-shaped groove 47 for engaging with the metal mesh 2 is provided between the fixing part 44 and the clamping part 45. The arc-shaped groove allows for better contact with the metal mesh, improving the fastening effect. When connecting the clamp to the metal mesh, first, the clamping part and the fixing part are separated at a certain angle. The wires of the metal mesh are aligned with the arc-shaped groove, and the engagement angle with the metal mesh is adjusted. Then, the locking bolt is tightened to press the clamping part firmly onto the fixing part.

[0031] As a further implementation, a rubber pad is provided on the arc-shaped groove. After clamping, the deformation can better fill the gap between the arc-shaped groove and the metal mesh, preventing relative rotation and further improving the stability after clamping and the reliability of the connection.

[0032] In a further specific embodiment, the adjusting rod 41 includes an adjusting ring 411, with threaded rods 412 threadedly connected to both ends of the adjusting ring 411. One end of the threaded rod 412 is fixedly connected to the fixing part 44, and the other end of the threaded rod 412 is hinged to the connecting seat 42. The threaded rods at both ends rotate in opposite directions. In this embodiment, four adjusting rods are provided. When it is necessary to adjust the pitch angle of the trim panel, the lengths of the four adjusting rods are adjusted to adjust the pitch angle of the connecting seat to adapt to the installation requirements of trim panels at different angles. When adjusting the length of the adjusting rods, the adjusting ring is rotated to change the engagement relationship between the adjusting ring and the threaded rods at both ends, thereby achieving the purpose of adjusting the overall length.

[0033] In addition, to facilitate quick connection and fixation during actual construction, the connecting base 42 is a rectangular base with a plug 48 on it. The inner wall of the trim panel 5 has a slot 49, and the plug 48 and slot 49 are inserted into each other. The rectangular base is equipped with a locking bolt 50 to lock the position of the plug 48. During construction, the trim panel and the rectangular base are first connected by the plug and slot, and finally locked by the locking bolt.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
