Description

Technical Field

[0001] This utility model relates to the field of decoration and renovation technology, and in particular to a prefabricated conversion layer ceiling for building decoration. Background Technology

[0002] When installing suspended ceilings in interior decoration, if the distance between the finished ceiling surface and the original structural ceiling surface is too large, a transition layer needs to be added as an intermediate connecting layer to avoid using excessively long hangers to connect the keel and improve the structural stability of the ceiling. Currently, transition layers are generally steel frame structures, which are spliced ​​together by multiple steel pipes via connectors. This traditional structure has many problems: First, the splicing process requires fixing each connector individually, which is cumbersome and inefficient. Second, due to the large number of connection points and the lack of precise positioning structures during the splicing of multiple steel pipes, the bottom surface of the steel frame is prone to tilting and unevenness after splicing. Third, most existing connection structures are fixed connections, which cannot achieve quick folding, increasing the difficulty of transportation and storage and hindering rapid on-site assembly. These problems not only affect the construction progress but also lead to deviations in the subsequent installation of hangers, keels, and plasterboard, ultimately affecting the overall flatness and aesthetics of the ceiling. Utility Model Content

[0003] The main purpose of this utility model is to propose a prefabricated conversion layer ceiling for building decoration, which aims to improve construction efficiency, ensure installation flatness, facilitate transportation and storage, and enhance structural stability.

[0004] To achieve the above objectives, the prefabricated transfer layer ceiling for architectural decoration proposed in this utility model includes:

[0005] A steel frame, comprising horizontal steel pipes, vertical steel pipes, and connecting steel pipes, wherein the vertical steel pipes are rotatably mounted on top of the horizontal steel pipes, and the connecting steel pipes are connected to the ends of the horizontal steel pipes. The vertical steel pipes can be rotated and folded or opened relative to the horizontal steel pipes. When in the open state, the vertical steel pipes and the horizontal steel pipes are at right angles.

[0006] A suspension rod, wherein the suspension rod is disposed at the bottom of the transverse steel pipe;

[0007] Keel, which is installed at the bottom of the hanger rod;

[0008] A gypsum board is provided at the bottom of the keel.

[0009] In one embodiment, one end of the horizontal steel pipe is provided with a connector, and one end of the vertical steel pipe is provided with a rotating shaft. The vertical steel pipe is rotatably connected to the connector through the rotating shaft.

[0010] In one embodiment, the connector is provided with a rotation space, and one end of the rotating shaft and the vertical steel pipe is located in the rotation space. When the vertical steel pipe is in the open state, the side wall of the rotation space holds the vertical steel pipe in place.

[0011] In one embodiment, the connector includes:

[0012] Two side plates are provided at intervals, and the lengths of the two sides of the side plates are not the same.

[0013] End plate, the end plate being located on the long side of the side plate;

[0016] The two side plates, the end plate, the first clamping block, and the second clamping block enclose and form the rotation space. The rotation shaft is rotatably connected to the two side plates. When the vertical steel pipe is in the open state, both sides of the vertical steel pipe abut against the first clamping block and the second clamping block, respectively. The position where the vertical steel pipe abuts against the first clamping block is above the rotation shaft, and the position where the vertical steel pipe abuts against the second clamping block is below the rotation shaft, thereby clamping the two sides of the vertical steel pipe and improving the clamping effect.

[0017] In one embodiment, when the vertical steel pipe is in a folded state, the bottom wall of the vertical steel pipe contacts and is flush with the top wall of the horizontal steel pipe.

[0018] In one embodiment, the outer end of the second holding block is provided with a first protrusion, the end of the transverse steel pipe is inserted into the first protrusion, and the end of the transverse steel pipe and the first protrusion are connected by screws.

[0019] In one embodiment, a rotating component is provided at the bottom of the vertical steel pipe, the rotating component is rotatably mounted on the rotating shaft, the vertical steel pipe is connected to the rotating shaft through the rotating component, a second protrusion is provided at the top of the rotating component, and the end of the vertical steel pipe and the second protrusion are connected by screws.

[0020] In one embodiment, the transverse steel pipe has a third protrusion at both ends, and the end sidewall of the connecting steel pipe has an insertion interface, which is inserted into the third protrusion.

[0021] In one embodiment, the bottom of the insertion interface is open so that the transverse steel pipe can be installed directly from top to bottom.

[0022] In one embodiment, the transverse steel pipe is connected to the third protrusion by a snap fastener.

[0036] Please see Figures 1 to 5 This application proposes a prefabricated conversion layer ceiling 1000 for architectural decoration, including a steel frame 1, hangers 2, keel 3, and gypsum board 4. The steel frame 1 includes a horizontal steel pipe 11, a vertical steel pipe 12, and a connecting steel pipe 13. The vertical steel pipe 12 is rotatably mounted on top of the horizontal steel pipe 11, and the connecting steel pipe 13 is connected to the end of the horizontal steel pipe 11. The vertical steel pipe 12 can be rotated and folded or opened relative to the horizontal steel pipe 11. When in the open state, the vertical steel pipe 12 and the horizontal steel pipe 11 are at a right angle. The hangers 2 are located at the bottom of the horizontal steel pipe 11, the keel 3 is installed at the bottom of the hangers 2, and the gypsum board 4 is located at the bottom of the keel 3.

[0037] The horizontal steel pipe 11 can be a square or round cross-section steel pipe, and its length is determined according to the actual ceiling dimensions. The vertical steel pipe 12 is connected to the horizontal steel pipe 11 via a rotating shaft 19, which can use a bearing or hinge structure to achieve rotation. The connecting steel pipe 13 is used to connect adjacent horizontal steel pipes 11, and can be connected by plug-in or bolt. The hanger 2 can be a threaded hanger 2 or an expansion bolt fixed to the bottom of the horizontal steel pipe 11. The keel 3 can be a light steel keel 3 or a wooden keel 3. The gypsum board 4 can be ordinary gypsum board 4 or fireproof gypsum board 4.

[0038] This technical solution utilizes a rotatable vertical steel pipe 12 design, allowing the steel frame 1 to be folded before installation for easy transportation and storage. During installation, simply opening the vertical steel pipe 12 to a right-angle position allows for quick assembly of the steel frame 1. Compared to traditional fixed welded steel frame 1 structures, this reduces on-site welding work, lowers construction difficulty, and avoids unevenness on the bottom surface of the steel frame 1 caused by welding deformation. The design of the connecting steel pipe 13 allows for the rapid splicing of multiple horizontal steel pipes 11, improving construction efficiency. The installation of the hangers 2, keel 3, and gypsum board 4 is based on the stable steel frame 1 structure, ensuring the overall flatness and stability of the ceiling.

[0039] Please see Figures 2 to 5 Furthermore, this application proposes that one end of the horizontal steel pipe 11 is provided with a connector 14, and one end of the vertical steel pipe 12 is provided with a rotating shaft 19. The vertical steel pipe 12 is rotatably connected to the connector 14 via the rotating shaft 19. This technical solution achieves the rotatable function of the vertical steel pipe 12 relative to the horizontal steel pipe 11 by setting a dedicated rotating connection structure. Specifically, the connector 14 provides an installation base for the rotating connection, and the rotating shaft 19 serves as the rotation center. The two work together to enable the vertical steel pipe 12 to fold or open.

[0040] Furthermore, this application proposes that the connector 14 is provided with a rotation space, and one end of the rotating shaft 19 and the vertical steel pipe 12 is located within the rotation space. When the vertical steel pipe 12 is in the open state, the side wall of the rotation space holds the vertical steel pipe 12 in place. This technical solution, by setting a rotation space with a specific structure, ensures that the vertical steel pipe 12 can be stably held in the open state, preventing it from shaking or shifting due to external forces.

[0041] Please see Figures 2 to 5 Furthermore, this application also proposes that the connector 14 includes two side plates 141, an end plate 142, a first retaining block 143, and a second retaining block 144. The two side plates 141 are spaced apart, and the lengths of the two sides of the side plates 141 are not the same. The end plate 142 is located on the long side of the side plate 141. The first retaining block 143 is located on the top of the end plate 142. The second retaining block 144 is located on the short side of the side plate 141, and the height of the second retaining block 144 is lower than the height of the end plate 142. The two side plates 141, the end plate 142, the first retaining block 143, and the second retaining block 144 enclose a rotation space. The rotation shaft 19 is rotatably connected to the two side plates 141. When the vertical steel pipe 12 is in the open state, the two sides of the vertical steel pipe 12 abut against the first retaining block 143 and the second retaining block 144, respectively. The vertical steel pipe 12 abuts against the first clamping block 143 above the rotating shaft 19, and the vertical steel pipe 12 abuts against the second clamping block 144 below the rotating shaft 19, thereby clamping the vertical steel pipe 12 on both sides and improving the clamping effect.

[0042] Specifically, the side plate 141 can be formed by stamping steel plate, with a length difference of 50-100mm between its long and short sides. The end plate 142 is welded and fixed to the long end of the side plate 141. The second clamping block 144 is a rectangular steel plate, welded and fixed to the short side of the side plate 141. The height of the rotation space is slightly larger than the diameter of the rotation shaft 19, and the width is slightly larger than the width of the vertical steel pipe 12. The rotation shaft 19 is connected to the side plate 141 through a bearing. When the vertical steel pipe 12 is opened, its upper outer side contacts the first clamping block 143, and its lower inner side contacts the second clamping block 144, forming a bidirectional limiting. As a preferred embodiment, rubber gaskets can be provided on the contact surfaces of the first clamping block 143 and the second clamping block 144 to reduce noise and wear.

[0043] Therefore, this technical solution, through the asymmetrical side plate 141 structure, combined with the first clamping block 143 and the second clamping block 144 located at different heights, achieves bidirectional limiting of the vertical steel pipe 12 when it is in the open state. Compared with the prior art, this structure can effectively prevent the vertical steel pipe 12 from swaying or shifting during use, improving the overall stability of the transition layer ceiling. At the same time, because the clamping action is distributed on both sides of the rotating shaft 19, the force is more balanced, avoiding the deformation problem of the connector 14 caused by unilateral force. This design simplifies the installation process and facilitates operation by construction personnel while ensuring structural strength.

[0044] Please see Figures 2 to 5 Furthermore, this application also proposes that when the vertical steel pipe 12 is in a folded state, the bottom wall of the vertical steel pipe 12 contacts and is flush with the top wall of the horizontal steel pipe 11.

[0045] Specifically, the vertical steel pipe 12 is rotatably connected to the horizontal steel pipe 11 via a rotating shaft 19. In the folded state, the vertical steel pipe 12 can rotate around the rotating shaft 19 until it is parallel to the horizontal steel pipe 11. At this time, the bottom wall of the vertical steel pipe 12 is in complete contact with the top wall of the horizontal steel pipe 11, and both are on the same horizontal plane. As a preferred embodiment, the contact surfaces of the vertical steel pipe 12 and the horizontal steel pipe 11 can be provided with anti-slip textures or rubber pads to enhance the friction when they are in contact and prevent accidental slippage. In addition, the installation position of the rotating shaft 19 needs to be precisely calculated to ensure that the vertical steel pipe 12 can be fully aligned when rotated to the folded position.

[0046] Therefore, this technical solution, by defining the specific positional relationship of the vertical steel pipe 12 when folded, enables the steel frame 1 structure to achieve compact folding when not in use. The design where the vertical steel pipe 12 is in complete contact with and flush with the horizontal steel pipe 11 reduces the space occupied after folding, facilitating transportation and storage; it also avoids interference between components in the folded state, improving operational convenience.

[0047] Please see Figures 2 to 5 Furthermore, this application proposes that the outer end of the second holding block 144 is provided with a first protrusion 16, and the end of the transverse steel pipe 11 is inserted into the first protrusion 16. The end of the transverse steel pipe 11 and the first protrusion 16 are connected by screws. This technical solution achieves rapid positioning and stable connection between the transverse steel pipe 11 and the connector 14 by setting the first protrusion 16 at the outer end of the first holding block 143. The plug-in joint structure facilitates alignment during construction, while the screw connection ensures the reliability of the connection. Compared with the prior art, this solution reduces the adjustment steps during the connection process, reduces the problem of uneven ceiling caused by connection deviation, and improves construction efficiency. Furthermore, this connection method is easy to disassemble, which is beneficial for the maintenance and adjustment of the ceiling structure. It also facilitates the switching of transverse steel pipes 11 of different models and lengths.

[0048] Please see Figures 2 to 5 Furthermore, this application proposes that the bottom of the vertical steel pipe 12 is provided with a rotating component 15, which is rotatably mounted on the rotating shaft 19. The vertical steel pipe 12 is connected to the rotating shaft 19 through the rotating component 15. The top of the rotating component 15 is provided with a second protrusion 17, and the end of the vertical steel pipe 12 and the second protrusion 17 are connected by screws. Thus, this technical solution achieves an indirect connection between the vertical steel pipe 12 and the rotating shaft 19 by setting an independent rotating component 15, where the rotating component 15 both undertakes the rotation function and provides a connection interface. The combination of the second protrusion 17 and the screw connection facilitates on-site installation and adjustment while ensuring connection strength. Compared with direct welding, this structure avoids the impact of welding deformation on rotation accuracy and facilitates later maintenance and replacement. The setting of the rotating component 15 makes the vertical steel pipe 12 more evenly stressed during folding and unfolding, reducing direct wear on the rotating shaft 19. At the same time, it facilitates the switching of vertical steel pipes 12 of different models and lengths.

[0049] Please see Figures 2 to 5 Furthermore, this application proposes that the transverse steel pipe 11 has third protrusions 18 at both ends, and that the end side wall of the connecting steel pipe 13 has an insertion interface, which is inserted into the third protrusions 18. This technical solution achieves rapid assembly of the steel frame 1 structure by directly inserting the third protrusions 18 at the end of the transverse steel pipe 11 into the insertion interface on the side wall of the connecting steel pipe 13. The lateral opening design of the insertion interface avoids the difficulty of precise alignment required for traditional end-to-end connections; during construction, the connection can be completed simply by moving the connecting steel pipe 13 laterally.

[0050] In this design, the transverse steel pipe 11 has third protrusions 18 at both ends, and the end sidewall of the connecting steel pipe 13 has an insertion interface that is inserted into the third protrusion 18. The bottom of the insertion interface is open, allowing the transverse steel pipe 11 to be installed directly from top to bottom. Therefore, this technical solution, through the bottom-opening insertion interface design, enables rapid vertical installation of the transverse steel pipe 11, avoiding the need for horizontal alignment or the use of auxiliary tools in traditional connection methods. Specifically, during construction, the transverse steel pipe 11 is simply pressed vertically downwards, allowing the third protrusion 18 to slide naturally into the insertion interface along the direction of gravity to complete the connection, significantly reducing the installation difficulty.

[0051] Meanwhile, the transverse steel pipe 11 is connected to the third protrusion 18 by a buckle.

[0052] In a preferred embodiment, the buckle can be a spring-loaded buckle structure, with the buckle's engaging portion matching the shape of the third protrusion 18. When the transverse steel pipe 11 is installed from top to bottom, the buckle automatically engages into the groove of the third protrusion 18 for fixation. Alternatively, the buckle can be a rotary buckle, where rotating the handle causes the claws to lock into the third protrusion 18. Furthermore, the buckle can be designed to be detachable for easy maintenance and adjustment later.

[0053] This technical solution simplifies the installation process of the horizontal steel pipe 11 and the third protrusion 18 through a snap-fit ​​connection, enabling rapid installation and fixation without the need for additional fasteners or tools. The snap-fit ​​connection ensures a secure connection between the horizontal steel pipe 11 and the third protrusion 18, preventing loosening or misalignment during construction. Therefore, this solution effectively solves the problems of cumbersome installation and bottom surface misalignment caused by numerous connection points in traditional steel pipe splicing, improving the installation efficiency and stability of the ceiling transition layer structure.

[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
