Description

Technical Field

[0001] The invention relates to the technical field of ceiling splicing, and in particular to an indoor high-altitude special-shaped GRG painted ceiling device. Background Art

[0002] GRG gypsum board material is a new type of decorative material. It has the advantages of general decorative materials such as good plasticity, strong surface adhesion, green environmental protection performance and good ornamental performance. It also has very excellent impact resistance, sound and light performance. The randomness of its shape is more sought after by architectural masters. Therefore, it has been increasingly used in contemporary antique public buildings, such as exhibition halls, museums, etc. These buildings generally have large space, large span, antique style of interior architecture, decorative shape, high color requirements, etc. Therefore, there are still some problems that need to be overcome in the construction of GRG ceiling splicing.

[0003] Through research on existing assembly methods, it was found that in the existing technical construction process, the diaphragm method is used to reasonably optimize the division according to the size and shape of the caisson, and then the frame structure is constructed to ensure the integrity of the frame pattern, and then holes for assembling GRG ceiling panels are reserved. When constructing the holes, a GRG ceiling panel is first installed on the edge of the ceiling (close to the frame), and during the assembly process, the central axis position, front and rear position, etc. need to be repeatedly checked until the positioning is accurate, leveled and corrected, and then fixed and hoisted on the nut, and then the next GRG panel is installed according to the height and position of the first ceiling panel.

[0004] However, when assembling the last GRG ceiling board, since the surrounding structures have been completed, workers are required to either enter the artificial passage reserved in the steel frame transfer layer to fix the hangers and adjacent panels, or to make additional holes in the surrounding structures and repair them after the assembly is completed. However, this limits the workers' operating space, increases safety risks, and increases the complexity and time cost of construction. In addition, the existing traditional method of splicing and installing GRG boards requires workers to constantly position, level and align, which is not only time-consuming but also labor-intensive, affecting construction efficiency and quality.

[0005] Based on this, it is necessary to study an indoor high-altitude special-shaped GRG painted ceiling device which is easy to position and level, convenient to construct, and effectively improves construction efficiency. Summary of the invention

When adjacent GRG plates are adapted and aligned, the end of the arc-shaped top head is pressed in the limiting groove and can slide down into the card slot, so that the adjacent GRG plates are fixedly docked together.

[0008] Furthermore, the top of the fixing seat is welded and fixed to the bottom of the suspension rod, and a strip-shaped avoidance hole is opened in the middle of the fixing seat, and the avoidance hole runs through to the bottom of the fixing seat to form an assembly space for installing the hanging rod on the top of the GRGB board.

[0009] Furthermore, a pin is installed in the fixing seat for transverse rotation, and the top of the hook is fixedly sleeved on the pin in the fixing seat.

[0010] Furthermore, the bottom of the hook is an inclined structure, and a baffle is fixed on the rear side wall of the hook, and the width of the baffle is greater than the width of the avoidance hole.

[0011] Furthermore, a U-shaped connecting frame is fixed to the outer side of the docking seat by bolts, and its opening is facing the locking seat. A connecting shaft is rotatably installed in the connecting frame, and the flip rod is fixedly sleeved on the connecting shaft.

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Example 1. This example aims to provide an indoor high-altitude special-shaped GRG painted ceiling device, which is used for quick hoisting, docking and locking of GRG boards. In some large-space ceiling decoration projects, due to the architectural decoration characteristics of large-space buildings such as high height, large span, large area, and complex shape, it is easy to cause deformation and cracks in the GRG ceiling decoration, affecting the decorative effect. In addition, the positioning and installation process between the GRG board ceilings and the parts docked with the wall is relatively cumbersome, resulting in poor surface flatness and easy cracking in the later stage. Therefore, this example provides an indoor high-altitude special-shaped GRG painted ceiling device, which can not only be used for docking and fixing between adjacent GRG boards, but also can quickly realize the hoisting and fixing of the ceiling boards.

[0023] The present embodiment provides an indoor high-altitude special-shaped GRG painted ceiling device, including a hanging assembly 4, a docking locking assembly 6 and a driving assembly, wherein the hanging assembly includes a hanger 41, a fixing seat 42, a pin 43 and a hook 45, and the top of the hanger is fixed to the steel frame conversion layer 1 by a fastener 5, and the fastener can be an expansion bolt, etc., and horizontal supports or oblique supports can be welded at the hanger with angle steels of different lengths to prevent the plate from shaking. The steel frame conversion layer is welded by a keel frame, wherein the vertical keel can be fixed to the structural top plate with expansion bolts. During actual construction, the main steel frame of the GRG ceiling is adaptively reinforced with steel sections according to the requirements of the drawings (fasteners and steel frame conversion layers are prior art and will not be elaborated here).

[0024] like Figure 1 and 2 As shown, the top of the suspension rod is vertically fixed on the steel frame transfer layer by fasteners, the fixing seat 42 is welded and fixed to the bottom of the suspension rod, and a strip-shaped avoidance hole 44 is opened in the middle of the fixing seat, and the avoidance hole runs through the bottom of the fixing seat to form an assembly space for the installation of the hanging rod on the top of the GRG board. The pin 43 is installed on the fixing seat in a lateral rotation, and the top of the hook 45 is fixedly sleeved on the pin in the fixing seat. The bottom of the hook is an inclined structure, and the hook body itself can rotate inside and outside the avoidance hole. During the actual lifting construction, a hanging rod 22 is pre-set on the GRG board, and a gasket 21 is welded at the bottom of the hanging rod 22. The gasket can be fixedly installed on the top of the GRG board by bolts, and the gasket and hanging rod can also be pre-buried in advance when the GRG board is processed and produced.

[0025] When construction workers are carrying out GRG board ceiling construction, they use tools such as laser projectors to guide the GRG board hanging points to the ceiling board installation position based on on-site positioning, so that the hanging rod is inserted from bottom to top into the avoidance hole on the fixed seat, and when the hanging rod contacts the inclined surface at the bottom of the hook, it can press the hook upward to make it swing out of the avoidance hole with the pin as the center, until the hanging rod moves upward to the assembly space 47 formed between the hook and the avoidance hole. At this time, the hanging rod has no contact with the hook, and the hook naturally swings inward to the position below the hanging rod in the avoidance hole, and the hanging rod falls and is hoisted on the hook accordingly.

[0026] Furthermore, a baffle 46 is fixed on the rear side wall of the hook, and the width of the baffle is greater than the width of the avoidance hole. Therefore, when the hook swings into the avoidance hole, the two sides of the baffle can fit on the side walls of the fixing seat on both sides of the avoidance hole, so that the hook can be adapted to swing into the avoidance hole. This embodiment hoisting and connecting the GRG board effectively ensures the stability and safety of the GRG board during the hoisting process.

[0027] like Figure 3-5 As shown, the docking locking assembly 6 includes a docking seat 61, a locking seat 62, a flip rod 64, a spring 66 and an arc-shaped head 67, etc., wherein the docking seat 61 and the locking seat 62 are fixed on both sides of the GRG board respectively, and the docking seat on one GRG board is adjacent to the locking seat on the adjacent GRG board. Specifically, as Figure 3 As shown, a connecting frame 63 is fixed to the outer side of the docking seat by bolts. In this embodiment, the connecting frame is a U-shaped structure with its opening facing the locking seat. A connecting shaft 65 is rotatably installed in the connecting frame, and a flip rod 64 is fixedly mounted on the connecting shaft 65, so that when the connecting shaft is driven to rotate, the flip rod can be driven to rotate synchronously.

[0028] like Figure 3 and Figure 5As shown, a limited stop 68 is fixed on the end of the flip rod away from the connecting frame, and the arc-shaped top 67 is slidably mounted on the flip rod, and a spring 66 is provided between the arc-shaped top and the stop, and the two ends of the spring are respectively fixedly connected to the two, so that the arc-shaped top can slide back and forth on the flip rod under the action of the spring.

[0029] like Figure 3 and Figure 4 As shown, one side of the connecting shaft on the docking seat extends out of the connecting frame and is connected to a driving assembly. Under the action of the driving assembly, the flip rod is driven to swing inward and outward. This embodiment provides a structure of a driving assembly, including a support seat 81, a driven bevel gear 82, a spline shaft 83 and a driving bevel gear 84, wherein the inner side of the spline shaft is matched and sleeved on the end of the connecting shaft 65, and the outer side of the spline shaft is fixedly sleeved with a shaft sleeve, the support seat 81 and the driven bevel gear 82 are fixedly sleeved on the spline shaft through the shaft sleeve, the support seat 81 is an L-shaped structure, the driven bevel gear 82 is meshed with the driven bevel gear for transmission, and the driving shaft in the driven bevel gear 82 is rotatably installed on the support seat, and its bottom extends vertically downward. A cross groove is also provided on the bottom surface of the driving shaft for matching with a cross screwdriver.

[0030] The drive assembly in this embodiment is arranged in this way. When the GRG plate is hoisted on the fixed seat at the bottom of the suspension rod, the long-arm screwdriver is matched with the cross groove at the bottom of the central shaft of the active bevel gear, so that the central shaft can be rotated clockwise or counterclockwise, and the active bevel gear is driven to rotate. The driven bevel gear is driven to rotate through the meshing of the active bevel gear and the driven bevel gear, and then the connecting shaft 65 is driven to rotate, thereby prompting the flip rod to swing toward the locking seat with the connecting shaft as the center, so as to facilitate locking with the card slot on the locking seat.

[0031] like Figure 3 As shown, the bottom of the locking seat 62 is fixed on the top of the GRG plate, and the side of the locking seat away from the docking seat is an arc-shaped curved surface structure, and a limiting groove 70 is also opened in the middle. A card slot 69 is opened at the bottom of the curved surface structure, and the card slot 69 is on the same plane as the connecting axis on the docking seat. Therefore, when the flip rod swings downward to the horizontal direction, the arc-shaped top head 67 can be matched and installed in the card slot of the docking seat.

[0032] Specifically, in this embodiment, when two adjacent GRG boards are adapted to be docked, or when the GRG board is adapted to be docked with the side wall, the driving assembly controls the flip rod to rotate toward the docking seat, so that the flip rod rotates downward in the limit groove on the docking seat, and at the same time, when it rotates to the top of the limit groove, the outer end surface of the arc-shaped top head contacts the curved surface structure of the docking seat, and as the flip rod rotates, the arc-shaped top head moves along the curved wall of the docking seat, and at the same time, the spring is compressed and stores energy. When the arc-shaped top head slides to the slot position, the spring elastic force is released and prompts the arc-shaped top head to be adapted to be mounted in the slot 69, thereby ensuring close contact between adjacent GRG boards while still having room for movement.

[0033] In addition, if Figure 6 As shown, elastic pressure pads 9 are fixed on the side walls of adjacent GRG boards. The pressure pads are made of elastic materials, such as sponge layers or rubber pads. On the one hand, when adjacent GRG boards are butt-jointed, the pressure pads can effectively improve the flatness and verticality between adjacent boards through the butt contact of adjacent pressure pad structures. On the other hand, they can adapt to the slight displacement caused by the extrusion, deformation or vibration of the boards in a long-term environment, ensure the stability of the connection, and extend the service life of the GRG boards. At the same time, after the GRG boards are assembled, the overall surface can be made smooth without obvious gaps, thereby improving the decorative effect.

[0034] Description of working principle: The indoor high-altitude special-shaped GRG painted ceiling device provided in this embodiment, during actual construction, according to the requirements of the construction drawings, a steel frame transfer layer is installed on the structural top plate, and then the top of the hanger is vertically fixed to the steel frame transfer layer by fasteners. Before construction, according to the design drawings, the construction personnel need to pre-weld gaskets and hanging rods on the top of the GRG board to ensure the accuracy of the installation position, and then use tools such as laser projectors to guide the GRG board hanging point to the ceiling board installation position according to the on-site positioning, and insert the hanging rod into the corresponding avoidance hole of the fixing seat from the bottom to hang it on the hook.

[0035] After the lifting is completed, connect the screwdriver with the matching connection of the active shaft 85 on the active bevel gear, rotate the screwdriver and drive the meshing transmission between the bevel gears, so that the connecting shaft 65 drives the flip rod to flip, and the flip rod swings downward and matches the arc-shaped top with the slot of the docking seat, so that the arc-shaped top on the flip rod is clamped in the slot of the locking seat under the action of the spring, so as to achieve close docking and locking between the GRG plates or between the GRG plates and the wall.

[0036] It should be noted that in actual application, multiple sets of hanging rod structures can be pre-set on the GRG boards in each construction unit cell, and at least one set of docking locking components can be set on both sides of the board respectively, so as to realize the docking assembly between adjacent GRG boards and between the GRG boards and the wall, which not only ensures tight docking, but also can adapt to the slight deformation or displacement that may occur in the GRG boards during long-term use, so as to maintain the stability and durability of the connection.

[0037] The indoor high-altitude special-shaped GRG painted ceiling device provided in this embodiment greatly improves the installation efficiency and safety of GRG boards, especially in large-space buildings, enhances the connection stability between GRG boards, shortens the construction period, and reduces the labor intensity of workers. In high-altitude and complex-shaped construction environments, it provides a more flexible and safe solution to meet the needs of modern architectural decoration.

[0038] Embodiment 2: Based on Embodiment 1, this embodiment further explains the installation position of the driving component.

[0039] like Figure 7 As shown, in this embodiment, the docking seat and the locking seat are respectively embedded in the GRG board. When the GRG prefabricated components are manufactured, the docking seat and the locking seat are embedded in the board body in advance, thereby ensuring the integration of the docking seat and the locking seat with the GRG board, and enhancing the overall stability and aesthetics. A mounting groove 11 is provided on the GRG board to accommodate the drive assembly, and a through hole is provided on the board body for a screwdriver to pass through to screw the driving shaft. When the docking is completed, the screwdriver is withdrawn from the through hole, and the through hole is blocked from the engraved surface of the GRG board, that is, the bottom surface, which prevents the entry of dust and debris and keeps the surface of the GRG board flat and smooth.

[0040] With this arrangement, the mounting groove can better adapt to the size of the driving assembly, thereby avoiding interference with the driving assembly when the panels are docked, and avoiding damage to the surface of the GRG board due to improper installation; at the same time, since the docking seat and locking seat are pre-embedded in the board body, the seismic resistance and durability of the GRG prefabricated components are also improved, enabling them to maintain good performance in various complex environments.

[0041] Embodiment 3, as Figure 8 As shown, this embodiment also provides another installation structure of the drive assembly.

[0042] The drive assembly in this embodiment is an existing 90-degree universal joint structure, one end of the shaft is matched and fixed with the connecting shaft on the docking seat in the horizontal direction, which is convenient for transmitting force and torque in the horizontal direction; the other end of the shaft is vertically arranged in the installation groove on the GRG board, the bottom corresponds to the perforation on the board body, and a cross groove is provided at the bottom for matching with a screwdriver to facilitate the screwing operation. The drive assembly of this embodiment is arranged in this way, with simple structure, convenient operation and stronger practicality.

[0043] Embodiment 4, as Fig. 9 As shown, this embodiment provides another installation structure of the drive assembly.

[0044] The driving assembly in this embodiment includes a bead 12 and a rotating wheel 13, and the rotating wheel is matched and mounted on the connecting shaft 65. A toothed slot 14 is provided in the middle of the rotating wheel. The bead is mounted on the rotating wheel, and the outer diameter of the bead matches the inner diameter of the slot in the rotating wheel. The bottom of the bead extends to the gap between adjacent GRG boards or between the GRG board and the wall. By pulling both sides of the bead and utilizing the clamping connection between the bead body and the slot, the rotating wheel can be rotated in different directions accordingly.

[0045] For example, when the right side of the annular bead is pulled downward, it can drive the rotating wheel to rotate clockwise, and synchronously drive the driving shaft and the flip rod to rotate clockwise. When the left side of the annular bead is pulled downward, it can drive the rotating wheel to rotate counterclockwise, and synchronously drive the driving shaft and the flip rod to rotate counterclockwise.

[0046] The operating method of the driving assembly provided in this embodiment not only simplifies the installation and adjustment process and reduces the difficulty of operation, but also improves the flexibility and reliability of the entire connection structure. Whether in the installation, adjustment or maintenance of the GRG board, the staff can easily achieve precise control of the connection structure by pulling the pull bead; and because the pull bead is cleverly hidden in the gap between the GRG board or the wall, the flatness of the GRG board assembly is also guaranteed.

[0047] Embodiment 5: Based on the above embodiments 1-4, this embodiment further illustrates the installation structure of the flip rod.

[0048] like Fig.10As shown, in order to prevent the arc-shaped top head from being stuck by the top surface of the locking seat under the action of the spring before the flip rod falls into the limiting groove of the locking seat, so that it cannot slide along the arc-shaped end of the top of the locking seat into the outer groove, the present embodiment provides a limiting structure symmetrical to the arc-shaped top head and the spring on the flip rod, the limiting structure includes an arc-shaped top block and a top spring, and the arc-shaped top block naturally presses the arc-shaped top head toward the distal end under the action of the top spring, and at the same time compresses the spring. When the flip rod is driven by the driving assembly to rotate toward the locking seat, it can match with the top of the locking seat and slide along the curved surface into the groove.

[0049] Such a configuration of the present embodiment effectively avoids the problem that the arc-shaped top head is stuck by the top surface of the locking seat due to the action of the spring before the flip rod falls into the limiting groove of the locking seat. It not only enhances the contact stability between the flip rod and the locking seat, but also improves the impact resistance of the flip rod during the rotation process, so that the staff does not need to worry about the flip rod getting stuck or misaligned during the rotation process, thereby improving work efficiency.

[0050] The embodiments of the present invention described above do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is to adopt the design of the hook and avoidance hole with an inclined structure, which simplifies the lifting process and improves the efficiency and safety of the lifting. The matching design of the flip rod and the arc-shaped head enables the GRG board to be automatically locked when docked, and has an elastic margin, which effectively reduces the probability of plate deformation and cracking, and the ceiling board can be quickly lifted and fixed through the cooperation of the lifting assembly and the docking locking assembly. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
