Description

Technical Field

[0001] The present application relates to the technical field of unit curtain walls, and in particular to special-shaped unit curtain walls based on BIM. Background Art

[0002] BIM broadly refers to the use of disciplines such as architecture, engineering, and civil engineering, using electronic information technology as a modeling guide and retaining construction information to create traceable and easily simulated building information models. Buildings and structures constructed using BIM facilitate pre-construction planning and facilitate targeted maintenance and traceability later on, leading to its widespread adoption and application. The construction of special-shaped unitized curtain walls is a prime example of BIM-based construction.

[0003] In the actual construction of existing BIM-based special-shaped unitized curtain walls, construction workers often first install the keel frame used to mount the special-shaped curtain wall on the building's exterior wall based on the modeling information. They then install individual special-shaped curtain wall panels onto the keel frame, assembling adjacent special-shaped curtain walls on the same keel frame to form the special-shaped unitized curtain wall on the building's exterior wall.

[0004] However, when construction workers install independent special-shaped curtain walls one by one on the keel frame on the exterior wall of the building, there is a problem that adjacent special-shaped curtain walls are difficult to abut and assemble, which greatly increases the construction difficulty for construction workers and needs to be improved. Summary of the Invention

[0005] In order to improve the problem of high construction difficulty of special-shaped unit curtain walls on buildings, the present application provides a special-shaped unit curtain wall based on BIM.

[0006] The BIM-based special-shaped unit curtain wall provided in this application adopts the following technical solutions:

[0007] The BIM-based special-shaped unit curtain wall includes a curtain wall portion, a wall mounting portion and a fixing portion; the wall mounting portion includes a wall mounting keel and a wall mounting mechanism, and the wall mounting keel is arranged on a building body for installing the special-shaped unit curtain wall through the wall mounting mechanism; the curtain wall portion includes a splicing keel, a matching mechanism and multiple special-shaped curtain walls, and the multiple special-shaped curtain walls are installed on the splicing keel through the matching mechanism, and the multiple special-shaped curtain walls located on the same splicing keel abut against each other; the wall mounting keel is provided with an assembly groove for the splicing keel to be inserted into, and the fixing portion is arranged in the side wall of the assembly groove, so as to position the splicing keel inserted into the assembly groove in the side wall of the assembly groove.

[0008] By adopting the above technical solution, the wall mounting keel is quickly fixed to the outer wall of the building through the wall-mounting mechanism, and multiple special-shaped curtain walls are quickly installed on the splicing keel through the mounting mechanism, which helps to reduce the tediousness of construction workers in installing special-shaped curtain walls one by one on the outer wall of the building and abutting and assembling them; after the splicing keel is inserted into the inner cavity of the assembly groove, the fixing part fixes the splicing keel and the wall mounting keel, so that multiple special-shaped curtain walls can be quickly installed on the outer wall of the building to form a unit curtain wall; this process reduces the construction difficulty of construction workers by installing multiple special-shaped curtain walls on the building at the same time, and effectively ensures the installation stability of the unit curtain wall on the outer wall of the building.

[0009] In a specific feasible implementation scheme, the mounting mechanism includes a positioning support plate, a plug-in plate and mounting bolts. The plug-in plate is arranged on each special-shaped curtain wall, the positioning support plate is arranged on the material connection keel, and a limiting channel for the plug-in plate to be inserted and slid is provided through the positioning support plate; the mounting bolts are arranged on the positioning support plate to position the plug-in plate in the side wall of the limiting channel.

[0010] By adopting the above technical solution, after the plug-in plate is pushed into the inner cavity of the limiting channel, the plug-in plate and the positioning plate are fixedly connected by bolts, thereby realizing the rapid positioning of the special-shaped curtain wall on the material connection keel; in addition, as the plug-in plate slides along the length direction of the limiting channel, adjacent special-shaped curtain walls can be quickly pushed against each other on the same wall keel to form a structurally stable unit curtain wall.

[0011] In a specific possible implementation scheme, the mounting mechanism further includes a correction bar, which is provided on each special-shaped curtain wall, and an adaption channel for the correction bar to press into and slide is provided through the material splicing keel.

[0012] By adopting the above technical solution, the correction strip is inserted into the inner cavity of the matching adapter channel, so that the connection strength and installation stability of the special-shaped curtain wall on the splicing keel are greatly improved, thereby effectively ensuring the position stability and application stability of the special-shaped curtain wall after installation.

[0013] In a specific possible implementation scheme, the wall mounting mechanism includes a wing extension plate and locking bolts. The wing extension plate is arranged on the wall keel, and the locking bolts are used to position the wing extension plate on the building.

[0014] By adopting the above technical solution, the wing extension plate increases the contact area between the wall keel and the building body. The locking bolt passes through the wing extension plate and is threaded on the outer wall of the building body, so that the wing extension plate is fixedly connected to the outer wall of the building body, thereby enabling the wall keel to be quickly and stably fixed to the building body, which helps to ensure the installation stability of the unit curtain wall on the building body.

[0015] In a specific possible implementation scheme, the connecting part includes a material connecting screw and a stop nut, the material connecting screw is arranged in the side wall of the assembly groove, and the material connecting screw is passed through the material connecting keel entering the assembly groove; the stop nut is threadedly connected to the material connecting screw to position the material connecting keel in the side wall of the assembly groove.

[0016] By adopting the above technical solution, after the end of the connecting screw rod close to the wall mounting keel is pressed into the inner cavity of the assembly groove, the connecting screw rod passes through the connecting keel to reduce the phenomenon of the connecting keel being separated from the wall mounting keel; the locking nut is tightened on the connecting screw rod so that the connecting keel and the wall mounting keel are fixedly connected as a whole to ensure the installation stability of the unit curtain wall on the building.

[0017] In a specific feasible implementation scheme, the fixing part also includes a back-pull mechanism, which includes a connecting screw, an operating rod and two inner connecting tubes; the operating rod is arranged on the connecting screw, and the two ends of the connecting screw are respectively connected to the inner connecting tubes with threads; one of the inner connecting tubes is arranged on the special-shaped curtain wall, and the other inner connecting tube is arranged on the wall keel.

[0018] By adopting the above technical solution, the operating rod makes it easy for construction workers to quickly rotate the connecting screw rod, so that the connecting screw rod is simultaneously connected to the two inner connecting tube threads, thereby ensuring the connection strength and connection stability between the special-shaped curtain wall and the wall keel, and improving the position stability and application stability of the unit curtain wall on the building.

[0019] In a specific possible implementation scheme, the wall mounting part also includes a supporting mechanism, which includes an extension touch plate and a stabilizing component; the extension touch plate is arranged on the wall mounting keel to receive the material receiving keel; a preset groove is provided on the extension touch plate, and one end of the stabilizing component is arranged in the side wall of the preset groove, and the other end is against the special-shaped curtain wall.

[0020] By adopting the above technical solution, the extended touch plate receives the part of the splicing keel away from the wall-mounting keel, making the unit curtain wall easy to install while effectively ensuring the position stability of the splicing keel on the wall-mounting keel; the stabilizing component abuts against the special-shaped curtain wall, thereby ensuring the position stability of the special-shaped curtain wall relative to the extended touch plate, thereby improving the application stability of the special-shaped curtain wall.

[0021] In a specific feasible implementation scheme, the stabilization assembly includes a stabilization block, a docking bar, a fixing bolt and multiple groups of movable parts; the stabilization block is arranged at one end of the docking bar through multiple groups of movable parts, and the other end of the docking bar is inserted into the side wall of the preset groove, and the fixing bolt is arranged on the extension plate to position the docking bar in the side wall of the preset groove.

[0022] By adopting the above technical solution, the connecting strip is fixed to the side wall of the preset groove by fixing bolts. After the stabilizing block is against the special-shaped curtain wall, the movable part reacts to the special-shaped curtain wall through its own elastic force in a compressed state, so as to reduce the connection gap between the special-shaped curtain wall and the connecting keel, and improve the position stability and application stability of the special-shaped curtain wall on the exterior wall of the building.

[0023] In a specific possible implementation manner, a plurality of latching grooves are further provided on the docking bar, and the plurality of latching grooves are distributed at intervals along the extension direction of the docking bar.

[0024] By adopting the above technical solution, the spaced positioning grooves facilitate the quick tightening of the fixing bolts, so that the docking strip can be quickly positioned in the preset groove cavity, thereby effectively ensuring the convenience of positioning the docking strip in the preset groove cavity.

[0025] In summary, this application has the following beneficial technical effects:

[0026] 1. Multiple pieces of special-shaped curtain walls are quickly installed on the splicing keel through the mounting mechanism, allowing them to be assembled into unit curtain walls in advance for future use. After the splicing keel is inserted into the inner cavity of the assembly slot, the fastening part securely connects the splicing keel and the wall mounting keel, allowing multiple pieces of special-shaped curtain walls to be simultaneously and quickly positioned on the exterior wall of the building, thereby greatly improving the work efficiency of construction workers in installing unit curtain walls and reducing the construction difficulty for construction workers.

[0027] 2. The extended touch plate is used to support the end of the splicing keel away from the wall-mounting keel, thereby improving the connection strength between the splicing keel and the wall-mounting keel; the stabilizing component ensures the position stability and application stability of the special-shaped curtain wall on the exterior wall of the building by abutting the special-shaped curtain wall, thereby reducing the construction difficulty of the construction workers and ensuring the position stability of the unit curtain wall after installation.

DETAILED DESCRIPTION

[0034] The embodiments of the present application disclose a special-shaped unit curtain wall based on BIM.

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] Reference Figure 1 The BIM-based special-shaped unit curtain wall includes a curtain wall portion 1, a wall mounting portion 2, and a fixing portion 3. The wall mounting portion 2 is mounted on the exterior wall of the building for mounting the special-shaped unit curtain wall. The curtain wall portion 1 is mounted on the wall mounting portion 2 via the fixing portion 3, so that multiple curtain walls can be quickly mounted on the exterior wall of the building to form a unit curtain wall.

[0037] Reference Figure 2 The wall mounting portion 2 includes a wall keel 21 and a wall mounting mechanism 22. The wall keel 21 can be made of steel. The wall mounting mechanism 22 includes flanges 221 and locking bolts 222. The flanges 221 are integrally formed on both sides of the width of the wall keel 21. Each flange keel 221 faces the side wall of the building and is coplanar with the side wall of the wall keel 21 facing the building.

[0038] Reference Figure 2 In this embodiment, the locking bolts 222 can be expansion bolts. The wall keel 21 and the flange plate 221 are simultaneously abutted against the exterior wall of the building. The locking bolts 222 pass through the flange plate 221 and are screwed onto the exterior wall of the building, thereby securing the flange plate 221 to the exterior wall of the building and thereby quickly and stably securing the wall keel 21 to the exterior wall of the building.

[0039] Reference Figure 2 and Figure 3The curtain wall portion 1 includes a splicing keel 11, a mounting mechanism 12, and multiple special-shaped curtain walls 13. All special-shaped curtain walls 13 are installed on the splicing keel 11 through the mounting mechanism 12 to quickly form a unit curtain wall. As a result, construction workers only need to install the formed unit curtain wall on the wall mounting keel 21 to achieve the installation of multiple special-shaped curtain walls 13 on the building at the same time, reducing the phenomenon of construction workers installing the special-shaped curtain walls 13 one by one on the special-shaped curtain wall 13 and abutting and assembling them, which helps to reduce the construction difficulty of construction workers on the building.

[0040] Reference Figure 3 The mounting mechanism 12 includes a positioning plate 121, a plug-in plate 122, mounting bolts 123 and a correction strip 124. In this embodiment, the correction strip 124 can be a dovetail-shaped steel strip, which is welded to each special-shaped curtain wall 13. An adaptation channel 111 is provided along the length direction of the splicing keel 11. The inner diameter of the adaptation channel 111 is adapted to the outer circumference of the correction strip 124. The correction strip 124 is inserted into the inner cavity of the adaptation channel 111, so that the special-shaped curtain wall 13 can be quickly installed on the correction strip 124. As the correction strip 124 slides in the inner cavity of the adaptation channel 111, all the special-shaped curtain walls 13 on the correction strip 124 can be abutted against each other to form a unit curtain wall together.

[0041] Reference Figure 3 The positioning plate 121 is welded vertically to the splicing keel 11, and the plug-in plate 122 is welded vertically to each special-shaped curtain wall 13. The plug-in plate 122 on each special-shaped curtain wall 13 is loosely matched with the correction strip 124. A limited channel 1211 is provided along the length of the positioning plate 121. When the correction strip 124 is inserted into the inner cavity of the adaptation channel 111, the plug-in plate 122 is precisely inserted into the inner cavity of the limited channel 1211, thereby improving the stability of the special-shaped curtain wall 13 installed on the splicing keel 11. The construction personnel pass the mounting bolts 123 through the positioning plate 121 and screw them into the preset thread groove on the outer wall of the plug-in plate 122, so that the plug-in plate 122 is positioned in the inner cavity of the limited channel 1211, thereby ensuring the connection strength and position stability of the special-shaped curtain wall 13 installed on the splicing keel 11.

[0042] Reference Figure 3 and Figure 4 The wall keel 21 is also provided with an assembly groove 211, and the length of the inner cavity of the assembly groove 211 is adapted to the length of the material keel 11. The construction worker inserts the end of the material keel 11 close to the building body into the inner cavity of the assembly groove 211, so that the material keel 11 is initially overlapped on the wall keel 21.

[0043] Reference Figure 3 and Figure 4The fastening portion 3 is used to position the splice keel 11 on the wall-mounting keel 21. The fastening portion 3 includes a splice screw 31, a retaining nut 32, and a pull-back mechanism 33. The splice screw 31 is welded perpendicularly to the inner bottom wall of the mounting groove 211. When the end of the splice keel 11 closest to the building is inserted into the inner cavity of the mounting groove 211, the splice screw 31 passes through the splice keel 11 to prevent the splice keel 11 from being dislodged from the opening of the mounting groove 211. The retaining nut 32 is screwed onto the splice screw 31, positioning the splice keel 11 on the splice screw 31 and thereby quickly securing the splice keel 11 to the wall-mounting keel 21.

[0044] Reference Figure 2 and Figure 4 To improve the positional stability of the material splicing keel 11 on the wall mounting keel 21, the wall mounting portion 2 also includes a support mechanism 23, which includes an extension plate 231 and a stabilizing assembly 232. The extension plate 231 is integrally formed on the wall mounting keel 21 to receive the portion of the material splicing keel 11 outside the assembly groove 211, thereby improving the positional stability of the material splicing keel 11 on the wall mounting keel 21.

[0045] Reference Figure 4 The stabilizing assembly 232 includes a stabilizing block 2321, a docking bar 2322, fixing bolts 2323, and multiple sets of movable parts 2324. In this embodiment, the movable parts 2324 may be steel compression springs. All movable parts 2324 are welded to one end of the docking bar 2322 in a spaced relationship. The stabilizing block 2321 is welded to the end of all movable parts 2324 away from the docking bar 2322.

[0046] Reference Figure 4 A pre-set groove 2311 is provided on the end wall of the contact plate 231, away from the wall stud 21. The inner diameter of the pre-set groove 2311 matches the outer circumference of the docking strip 2322. Multiple locking grooves 23221 are also spaced and equidistantly provided on the sidewall of the docking strip 2322. In this embodiment, the locking grooves 23221 are threaded grooves that mate with the threads of the fixing bolts 2323.

[0047] Reference Figure 2 and Figure 4After the end of the docking strip 2322 away from the stabilizing block 2321 is inserted into the inner cavity of the preset groove 2311, the docking strip 2322 slides in the inner cavity of the preset groove 2311, allowing the fixing bolt 2323 to pass through the docking strip 2322 and be screwed into the inner cavity of any one of the positioning grooves 23221, thereby positioning the end of the docking strip 2322 located in the inner cavity of the preset groove 2311 within the side wall of the preset groove 2311. At this time, the stabilizing block 2321 abuts against the side wall of the special-shaped curtain wall 13 facing the wall keel 21, and the movable part 2324 reacts to the special-shaped curtain wall 13 through its own elastic deformation, thereby reducing the connection gap between the special-shaped curtain wall 13 and the material connection keel 11, thereby improving the connection stability of the special-shaped curtain wall 13 on the material connection keel 11 and helping to ensure the connection stability of the material connection keel 11 on the wall keel 21.

[0048] Reference Figure 3 and Figure 4 The reverse pull mechanism 33 is located on the side of the material receiving keel 11 away from the extension plate 231 to further enhance the stability of the installation of the special-shaped curtain wall 13 on the building. The reverse pull mechanism 33 comprises a connecting screw 331, an operating rod 332, and two inner connecting tubes 333. In this embodiment, the inner connecting tubes 333 can be internally threaded cylinders. One inner connecting tube 333 is welded to the side wall of the special-shaped curtain wall 13 facing the building, and the other inner connecting tube 333 is welded to the wall mounting keel 21. The central axes of the two inner connecting tubes 333 are collinear.

[0049] Reference Figure 3 and Figure 4 The operating rod 332 is welded to the outer edge of the connecting screw 331. One end of the connecting screw 331 is screwed into the side wall of one of the inner connecting tubes 333. After the special-shaped curtain wall 13 is installed on the wall keel 21 via the material connection keel 11, the construction worker rotates the operating rod 332 to thread the connecting screw 331 into the side wall of the other inner connecting tube 333. At this time, the two inner connecting tubes 333 are connected by the same connecting screw 331, ensuring the stability of the position of the special-shaped curtain wall 13 installed on the exterior wall of the building.

[0050] The implementation principle of the BIM-based special-shaped unit curtain wall in the embodiment of the present application is as follows: the special-shaped curtain wall 13 is inserted into the inner cavity of the adaptation channel 111 through the correction strip 124. At this time, the plug-in plate 122 is pressed into the inner cavity of the limiting channel 1211. The construction personnel fix the positioning plate 121 and the plug-in plate 122 by installing bolts 123 to position the special-shaped curtain wall 13 on the splicing keel 11, so that multiple special-shaped curtain walls 13 can be quickly and efficiently installed on the same splicing keel 11 and abut against each other.

[0051] Next, the construction worker inserts the splice keel 11 into the inner cavity of the assembly slot 211, passes the splice screw 31 through the splice keel 11, and screws the retaining nut 32 onto the splice screw 31, thereby firmly connecting the splice keel 11 to the wall mounting keel 21. At this point, multiple pieces of special-shaped curtain wall 13 are quickly installed on the building's exterior wall to form a unitized curtain wall. This process greatly improves the convenience and efficiency of installing unitized curtain walls on the building's exterior wall, effectively reducing the workload for construction workers.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
