DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments 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. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0027] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] On the one hand, the embodiment of the present application provides a GRG decorative panel 3 installation structure, including a base frame 2 and a connecting assembly 4. The base frame 2 is installed on a wall 1, and the base frame 2 includes a first wall 6 and a second wall 7 that are arranged opposite to each other. The connecting assembly 4 includes a rotating part 8, a hanging part 10, a connecting part 12, a connecting cable 11 and a driving component 9. The rotating part 8 is rotatably connected to the first wall 6, the connecting part 12 is connected to the GRG decorative panel 3, the connecting cable 11 connects the connecting part 12 and the rotating part 8, the hanging part 10 is connected to the base frame 2, the hanging part 10 is arranged above the connecting part 12, the connecting cable 11 is arranged around the hanging part 10, along the rotation axis of the rotating part 8, the rotating part 8 is provided with an axial hole 16, the cross section of the axial hole 16 is rectangular, the connecting part 12 is provided with a first limiting hole 17, the cross section of the first limiting hole 17 is rectangular, the second wall 7 is provided with a second limiting hole 18, the cross section of the second limiting hole 18 is rectangular, the driving component 9 is a rectangular parallelepiped structure adapted to the shape of the axial hole 16, the first limiting hole 17 and the second limiting hole 18, and the driving component 9 is inserted into the second limiting hole 18 via the axial hole 16 and the first limiting hole 17.

[0029] The base frame 2 is used to install and support the GRG decorative panel 3. The connection method between the base frame 2 and the wall 1 can be selected from the existing structures, which will not be repeated here. The base frame 2 can be a frame structure composed of angle steel.

[0030] One end of the connecting rope 11 may be provided with a hook, and the rotating part 8 may be provided with a hanging hole. By hanging the hook on the hanging hole, the connecting rope 11 can be detachably connected to the rotating part 8.

[0031] When the connecting rope 11 passes through the hanging part 10 and is connected to the rotating part 8, the GRG decorative panel 3 can be hung on the base frame 2 by the connecting rope 11 to form a preliminary fixation, which makes it easy for the installer to adjust the position of the GRG decorative panel 3. The installer does not need to keep supporting the GRG decorative panel 3 when adjusting the position of the GRG decorative panel 3, which reduces the workload of the installer and improves the installation efficiency.

[0032] In the embodiment of the present application, the hanging portion 10 may be a hanging wheel rotatably connected to the base frame 2, and the connecting rope 11 is wound around the outer peripheral wall of the hanging wheel.

[0033] Since the cross-section of the shaft hole 16 is rectangular, when the driving component 9 is inserted into the shaft hole 16, the rotating part 8 can be rotated by rotating the driving component 9. When the rotating part 8 rotates, the rotating part 8 can reel in the connecting rope 11, thereby enabling the GRG decorative panel 3 to be lifted through the connecting rope 11 for easy installation.

[0034] When the GRG decorative panel 3 is lifted into place, the driving component 9 is moved along the shaft hole 16, so that the driving component 9 can be simultaneously inserted into the shaft hole 16, the first limiting hole 17 and the second limiting hole 18. Since the cross-sections of the first limiting hole 17 and the second limiting hole 18 are also rectangular, on the one hand, the rotating part 8 is locked. On the other hand, the GRG decorative panel 3 can be supported by the driving component 9. On the other hand, the driving component 9 and the connecting rope 11 can simultaneously fix the GRG decorative panel 3, thereby improving the fixing reliability of the GRG decorative panel 3.

[0035] In some embodiments, the driving component 9 includes a main body 15 and a moving part 14. The main body 15 is inserted in the shaft hole 16 and the first limiting hole 17. Along the rotation axis of the rotating part 8, a plug hole is provided on the side of the main body 15 close to the second wall 7. The main body 15 is also provided with a limiting part 13. The main body 15 is provided with a sliding hole, which is connected to the plug hole. The axis of the sliding hole is perpendicular to the axis of the plug hole. The limiting part 13 is inserted in the sliding hole. The inner wall surface of the first limiting hole 17 is provided with a recessed part, which is used to accommodate the limiting part 13. One side of the moving part 14 is inserted in the plug hole, and the other side is inserted in the second limiting hole 18. The moving part 14 is provided with an inclined surface, which is used to push the limiting part 13 to move.

[0036] The main body 15 can be slidably matched with the shaft hole 16 , that is, there is no gap between the outer peripheral wall of the main body 15 and the inner wall surface of the shaft hole 16 .

[0037] The moving part 14 is inserted into the insertion hole so that the moving part 14 can be connected to the main body 15 and can move along the axial direction of the insertion hole relative to the insertion hole.

[0038] The moving portion 14 and the second limiting hole 18 are slidably matched, that is, there is no gap between the outer peripheral wall of the moving portion 14 and the inner peripheral wall of the second limiting hole 18 .

[0039] In the embodiment of the present application, the cross-section of the socket can be a polygonal structure, and the shape of the movable part 14 is adapted to the shape of the socket, so that when the movable part 14 is inserted into the socket, relative rotation cannot occur between the movable part 14 and the main body 15.

[0040] The inclined surface of the moving part 14 is used to drive the limiting part 13 to move, that is, when the moving part 14 moves into the insertion hole, the limiting part 13 is pushed to move out of the insertion hole under the action of the inclined surface, so that the limiting part 13 can enter the recessed part, thereby fixing the position of the driving component 9 relative to the connecting part 12. On the contrary, when the moving part 14 is moved in the direction of exiting the insertion hole, the limiting part 13 moves into the insertion hole, making it easier to insert the main body 15 into the first limiting hole 17.

[0041] In the embodiment of the present application, the movable part 14 and the main body 15 may be respectively provided with through holes for bolts to pass through, and the relative positions of the movable part 14 and the main body 15 can be fixed by passing the bolts through the through holes of the two and then connecting them with nuts.

[0042] In some embodiments, the first limiting hole 17 includes a first side located at the top and a second side located at the bottom, the main body 15 includes a third side close to the first side and a fourth side close to the second side, the width between the first side and the second side is greater than the width between the third side and the fourth side, and the recessed portion is arranged on the first side.

[0043] Under such a structure, the main body 15 and the first limiting hole 17 can form a clearance fit structure, that is, the main body 15 can move vertically relative to the first limiting hole 17. The recessed portion is arranged on the first side, so that the limiting portion 13 can not only limit the driving component 9, but also fine-tune the position of the GRG decorative panel 3. When the travel of the limiting portion 13 out of the insertion hole increases, the limiting portion 13 can lift the GRG decorative panel 3 to fine-tune the position of the GRG decorative panel 3 relative to the base frame 2.

[0044] In some embodiments, a rotating sleeve 20 is provided on the outer peripheral wall of the rotating part 8. A spiral groove 23 is provided on the outer peripheral wall of the rotating part 8 around the rotation axis of the rotating part 8. The rotating sleeve 20 is provided with a matching portion, which is inserted into the spiral groove 23. The moving part 14 is provided with a supporting portion 19, which abuts against the rotating sleeve 20. The rotating part 8 is also provided with a locking component, which is used to limit the axial position of the rotating sleeve 20 relative to the rotating part 8.

[0045] The connecting rope 11 is wound around the outer peripheral wall of the rotating sleeve 20 .

[0046] Under the action of the matching portion and the spiral groove 23 , when the rotating sleeve 20 moves axially relative to the rotating portion 8 , the rotating sleeve 20 can also rotate relative to the rotating portion 8 .

[0047] The abutting portion 19 may be detachably connected to the moving portion 14 , for example, the two may be connected by bolts.

[0048] When the abutting portion 19 abuts against the rotating sleeve 20 , the moving portion 14 moves relative to the main body 15 , and the abutting portion 19 can apply an axial force to the rotating sleeve 20 , so that the rotating sleeve 20 can further rotate to reel in the connecting rope 11 .

[0049] The locking component allows the rotating sleeve 20 to have two working states, one is an unlocked state, in which the rotating sleeve 20 can move axially relative to the rotating part 8, and the other is a locked state, in which the rotating sleeve 20 cannot move axially relative to the rotating part 8.

[0050] When the limiter 13 is driven by the moving part 14 to lift the connecting part 12, the connecting cable 11 is in a relaxed state, and it is difficult for the connecting cable 11 to fix the GRG decorative panel 3. Therefore, the rotating sleeve 20 is driven to rotate by the abutting part 19, and the rotating sleeve 20 further reels the connecting cable 11, so that the connecting cable 11 can be tightened to support the GRG decorative panel 3.

[0051] It should be noted that the rotation direction of the spiral groove 23 on the rotating portion 8 is configured so that when the abutting portion 19 pushes the rotating sleeve 20 , the rotating sleeve 20 can reel in the connecting rope 11 .

[0052] In some embodiments, the rotating portion 8 is provided with a shaft shoulder 22 , and the locking component includes a limiting ring 21 , which is sleeved on the rotating portion 8 and disposed between the rotating sleeve 20 and the shaft shoulder 22 .

[0053] The shoulder 22 can be arranged on the side of the rotating part 8 away from the second wall 7. When the abutting portion 19 abuts against the rotating sleeve 20 from the side of the rotating sleeve 20 close to the second wall 7, the limiting ring 21 can limit the rotating sleeve 20 so that it cannot move axially along the rotating part 8.

[0054] In some embodiments, the limiting ring 21 is an incomplete ring structure.

[0055] The incomplete ring structure of the limiting ring 21 facilitates the disassembly and assembly of the limiting ring 21 on the rotating part 8. Furthermore, the limiting ring 21 can be made of elastic material so that the two ends of the limiting ring 21 can be separated, so that the rotating part 8 can be inserted into the limiting ring 21 between the two ends of the limiting ring 21.

[0056] In some embodiments, the GRG decorative panel 3 is provided with embedded parts 5 , and the embedded parts 5 are used to be connected to the base frame 2 .

[0057] The embedded parts 5 are used to further fix the GRG decorative panel 3 , that is, after the GRG decorative panel 3 is initially fixed by the connecting assembly 4 , it is further fixed by connecting it to the base frame 2 through the embedded parts 5 .

[0058] The embedded part 5 can be connected to the base frame 2 by bolts, or the embedded part 5 can be welded to the base frame 2.

[0059] On the other hand, the embodiment of the present application provides a BIM-based construction method, which is applicable to the GRG decorative panel 3 installation structure in the above embodiment, including:

[0060] Establish a BIM model and simulate construction based on the BIM model. The specific software operation process of establishing a BIM template through BIM software is well known to those skilled in the art and will not be repeated here.

[0061] By simulating the construction through the BIM model, on the one hand, it is convenient to control the size of the GRG decorative panel 3 produced by the order. On the other hand, through the simulated construction, possible problems in the construction can be discovered in time, reducing the losses caused by on-site rework. On the other hand, based on the simulation of on-site construction, the construction organization plan can be optimized, and communication and coordination with units that may cause construction work surface collisions can be proposed in advance, reducing on-site work surface conflicts and improving construction efficiency.

[0062] Production of GRG decorative panels 3. When placing an order for GRG panels, the seam principle of the construction drawing and the BIM model should be strictly followed when ordering and processing the production. At the same time, the finished prefabricated modules should be classified and numbered according to the order drawings, and special modeling modules should be noted in advance to facilitate the installation of the corresponding panels according to the drawing numbers during on-site construction, ensuring the smoothness and integrity of the GRG finished surface. When GRG finished modules are brought to the site, they should be reasonably classified and grouped according to the module installation position, and try to avoid bumping and damaging the finished modules during transportation and installation.

[0063] Install the base frame 2, which can be a steel frame formed by a combination of steel materials. Before the steel frame is installed on the wall, the cutting and welding required for the steel frame itself can be completed first, thereby reducing the workload of high-altitude welding and reducing the safety risks of high-altitude operations.

[0064] Connect the GRG decorative panel 3 to the base frame 2. In the embodiment where the GRG decorative panel 3 is provided with a connecting component 4 and an embedded part 5, the GRG decorative panel 3 is firstly fixed by the connecting component 4, and then the base frame 2 connected with the embedded part 5 is further fixed to complete the GRG decorative panel 3.

[0065] In some embodiments, when establishing the BIM model, the special GRG decorative panels 3 are marked.

[0066] By marking the special GRG decorative panel 3, the risk of dimensional error during production is reduced, thereby improving construction efficiency.

[0067] In some embodiments, the GRG decorative panel 3 is provided with embedded parts 5, which are welded to the base frame 2, and dock reinforcement is performed between the embedded parts 5 and the base frame 2, and between the embedded parts 5 and the GRG decorative panel 3.

[0068] The welding between the embedded part 5 and the base steel frame must be firm, the weld surface must be flat and smooth, and there must be no quality defects such as pores, slag inclusions, weld nodules, incomplete penetration and lack of fusion.

[0069] The dock reinforcement is to use wrapping materials to wrap between the embedded parts 5 and the base frame 2, and between the embedded parts 5 and the GRG decorative panel 3. By performing dock reinforcement on the above two places, the safety and stability of the GRG can be improved. The wrapping material can be a mixture of high-strength gypsum powder, glass fiber and water dedicated to the GRG material. The specific mixing process is well known to those skilled in the art and will not be repeated here.

[0070] The above embodiments are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
