Description

Technical Field

[0001] This application relates to the technical field of building decoration, and in particular to a mineral wool board ceiling and a hoisting method. Background Technology

[0002] Mineral wool boards have noise reduction, sound absorption, sound insulation, fire resistance, and strong decorative properties, so they are often used as decorative ceiling materials.

[0003] The existing method for installing mineral wool boards involves first installing vertical hangers on the roof. The lower end of the hangers is connected to a load-bearing keel, which is perpendicular to the hangers. The lower surface of the load-bearing keel is connected to a main keel, which is perpendicular to the load-bearing keel. The main keel is connected to a secondary keel, which is perpendicular to the main keel. The secondary keel has protrusions on both sides. The main keel and the secondary keel enclose several rectangular areas. When placing the mineral wool board, the board is first vertically inserted through the rectangular frame, then placed horizontally within the rectangular frame and fixed in place. This completes the installation of the mineral wool board.

[0004] The aforementioned techniques require the mineral wool board to be vertically inserted through a rectangular frame and then placed horizontally within the frame, which is time-consuming and labor-intensive, resulting in low installation efficiency. Summary of the Invention

[0005] To improve the installation efficiency of mineral wool boards, this application provides a mineral wool board ceiling and hoisting method.

[0006] Firstly, the mineral wool board ceiling provided in this application adopts the following technical solution:

[0007] A mineral wool board ceiling and its installation method are applicable to roofs. The method includes a hanger, a load-bearing keel, a main keel, and a secondary keel. One end of the hanger is fixedly connected to the roof, and the length of the hanger is perpendicular to the roof. The load-bearing keel is horizontally positioned at the bottom of the hanger and connected to the hanger. The main keel is horizontally positioned below the load-bearing keel and connected to it, perpendicular to the load-bearing keel. The secondary keel is connected to the main keel and horizontally positioned, with its length perpendicular to the main keel. Clamping plates are slidably connected to opposite sides of the secondary keel, with the length of the clamping plates parallel to the length of the secondary keel. Installation grooves are formed along the length of the secondary keel on opposite sides, and support plates are slidably connected within these grooves. The support plates are positioned below the clamping plates and are parallel to them. Fixing components for fixing the support plates are provided at the secondary keel.

[0008] By adopting the above technical solution, the tray is first placed in the placement groove, and the fixing components fix the tray. The mineral wool board is then lifted horizontally upwards, moving it into the rectangular area enclosed by the main keel and secondary keel. During the movement of the mineral wool board, it first contacts the clamping plate and pushes the clamping plate upwards. After the mineral wool board moves above the tray, the fixing components release the tray, and the tray moves back into the placement groove. The upper surface of the tray and the lower surface of the mineral wool board abut against each other, making it less likely for the mineral wool board to fall downwards, thus completing the installation of the mineral wool board. There is no need to first vertically pass it through the rectangular frame and then place the mineral wool board horizontally within the rectangular frame, saving time and improving the installation efficiency of the mineral wool board.

[0009] Optionally, a first spring is fixedly connected to the side of the tray near the bottom wall of the placement groove. The end of the first spring away from the tray is fixedly connected to the bottom wall of the placement groove, and the extension and retraction direction of the first spring is parallel to the movement direction of the tray.

[0010] By adopting the above technical solution, when the entire pallet is in the placement groove, the first spring is in a compressed state. When the fixing component releases the fixing of the pallet, the first spring releases its elastic force and pushes the pallet to move outward. This eliminates the need for workers to manually move the pallet outward, thus providing convenience for workers.

[0011] Optionally, the secondary keel has a cavity inside, which is located above the mounting groove. The bottom end of the cavity is connected to the mounting groove. The fixing component includes a fixing rod and a second spring. The fixing rod is disposed in the cavity and is slidably connected to the secondary keel. The second spring is fixed between the fixing rod and the top wall of the wall. The support plate has a first fixing groove through it, and the fixing rod and the first fixing groove are inserted and adapted to each other.

[0012] By adopting the above technical solution, when the entire pallet is in the placement groove, the bottom end of the fixing rod extends into the first fixing groove, making it difficult for the pallet to move out of the placement groove. When the fixing rod is moved upward, the second spring is compressed, and at the same time, the bottom end of the fixing rod disengages from the first fixing groove, releasing the fixing of the pallet. The pallet then moves out of the placement groove, thus the fixing component achieves the fixing function of the pallet.

[0013] Optionally, a second fixing groove is provided on the upper surface of the pallet, and the second fixing groove and the fixing rod are plugged into and adapted to each other. The second fixing groove is located on the side of the first fixing groove close to the first spring.

[0014] By adopting the above technical solution, when the tray moves outside the placement groove, the second spring releases its elastic force, pushes the fixing rod downward, and inserts the fixing rod into the second fixing groove to fix the tray again, making it difficult for the tray to move into the placement groove.

[0015] Optionally, the secondary keel has vertical grooves on its opposite sides, and a slider is slidably connected to the secondary keel in the groove. The slider is fixedly connected to the clamp plate on the side away from the bottom wall of the groove and they correspond one-to-one. A third spring is fixed between the slider and the top wall of the groove, and the extension and retraction direction of the third spring is parallel to the length direction of the groove.

[0016] By adopting the above technical solution, when the mineral wool board pushes the clamping plate upward, the clamping plate drives the slider to move in the slide groove, and the third spring is compressed. The setting of the slider and the slide groove realizes the sliding connection between the clamping plate and the secondary keel. At the same time, the third spring always exerts a downward force on the clamping plate. The clamping plate and the support plate realize the clamping and fixing of the mineral wool board, which improves the stability of the mineral wool board fixing.

[0017] Optionally, the slide groove and the cavity are connected at the upper end, and the secondary keel is slidably connected to a lever at the connection between the slide groove and the cavity. The length direction of the lever is perpendicular to the fixed rod, and the end of the lever near the fixed rod is set as an inclined surface. The inclined surface is inclined from top to bottom towards the direction near the fixed rod. The side wall of the fixed rod is provided with a slot. The lever and the slot are inserted and adapted. The side of the lever away from the fixed rod is inclined from the middle towards both the upper and lower sides.

[0018] By adopting the above technical solution, during the upward movement of the slider, the slider and the lever abut against the inclined surface on the side away from the fixed rod, and push the lever to move towards the fixed rod. The end of the lever close to the fixed rod gradually moves towards the groove, and drives the fixed rod to move upward, so that the fixed rod and the first fixed groove are separated. At the same time, after the fixed rod and the first fixed groove are separated, the slider and the lever are separated, eliminating the need for the staff to manually move the fixed rod, thus providing convenience for the staff.

[0019] Optionally, the lower surface of the main keel is provided with a first connecting groove, which extends through the opposite sides of the main keel. The secondary keel is engaged with the first connecting groove. The upper surface of the secondary keel is provided with a second connecting groove, which extends through the opposite sides of the secondary keel. The main keel and the second connecting groove are engaged with each other. The main keel is provided with a connecting component for connecting with the secondary keel at the first connecting groove.

[0020] By adopting the above technical solution, the first connecting groove and the second connecting groove are aligned, and then the secondary keel is moved towards the main keel. The secondary keel moves into the first connecting groove, while the main keel is in the second connecting groove. Then, the secondary keel and the main keel are fixed by connecting components. The setting of the first connecting groove and the second connecting groove ensures that the lower surfaces of the main keel and the secondary keel are in the same horizontal plane, which improves the aesthetics of the ceiling.

[0021] Optionally, the secondary keel has slots on opposite sides, and the main keel has movable slots on opposite side walls of the first connecting slot. The connecting component includes a locking block and a fourth spring. The locking block is disposed in the movable slot and slidably connected to the main keel. The fourth spring is fixed between the locking block and the bottom wall of the movable slot. The extension and retraction direction of the fourth spring is parallel to the sliding direction of the locking block. The locking block and the slot are engaged and adapted. The end of the locking block away from the fourth spring is set as an inclined surface, and the inclined surface is inclined from top to bottom towards the direction of the fourth spring.

[0022] By adopting the above technical solution, during the process of the secondary keel moving into the first connecting groove, the secondary keel first abuts against the inclined surface of the locking block and pushes the locking block to move into the moving groove. The fourth spring is compressed. When the secondary keel moves into the first connecting groove, the fourth spring releases its elastic force and pushes the locking block to move into the locking groove, so that the end of the locking block away from the fourth spring extends into the locking groove, thereby realizing the locking and fixing of the secondary keel and the main keel.

[0023] Optionally, a threaded sleeve is rotatably connected to the upper surface of the supporting keel, the length direction of the threaded sleeve is perpendicular to the supporting keel, and the threaded sleeve is threadedly connected to the bottom end of the hanger rod.

[0024] By adopting the above technical solution, when the load-bearing keel and the hanger are connected, the threaded sleeve is rotated and the bottom thread of the hanger is connected. At the same time, by adjusting the length of the connection between the threaded sleeve and the hanger, the load-bearing keel can be kept in a horizontal state.

[0025] Secondly, this application provides a method for hoisting mineral wool board ceilings, employing the following technical solution:

[0026] A method for installing mineral wool board ceiling panels includes the following steps:

[0027] S1. Mark a horizontal line on the wall;

[0028] S2. Install hangers on the roof, and apply anti-rust paint to the hangers before installation;

[0029] S3. Install load-bearing keels at the bottom of the hanger rods, and adjust multiple load-bearing keels to be neat and at the same elevation;

[0030] S4. Install the main keel on the lower surface of the load-bearing keel, and fix the side keel with cement nails around the wall according to the elevation line on the wall. The end of the main keel is overlapped to the side keel and fixed.

[0031] S5. Install the secondary keel according to the size of the mineral wool board;

[0032] S6. Install the mineral wool boards in sequence. After the mineral wool boards are installed, clean the surface of the mineral wool boards.

[0033] By adopting the above technical solution, firstly, a horizontal line is drawn on the wall, and the hangers are installed on the roof for support. Then, the load-bearing keels are connected according to the horizontal line so that multiple load-bearing keels are at the same height and in a horizontal state. Next, multiple main keels are installed, also so that the main keels are at the same height and in a horizontal state. Side keels are installed to support the main keels. Then, secondary keels are installed. The secondary keels and main keels form multiple rectangular areas. Mineral wool boards are installed into the rectangular areas, and the mineral wool boards are cleaned to complete the installation of the mineral wool boards.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. Move the mineral wool board horizontally upwards. The mineral wool board pushes the clamping plate upwards. When the mineral wool board moves above the support plate, the fixing component releases the support plate. The support plate moves out of the placement groove. The upper surface of the support plate and the lower surface of the mineral wool board abut against each other to support the mineral wool board, thus completing the installation of the mineral wool board. It is not necessary to first pass it vertically through the rectangular frame and then place the mineral wool board horizontally in the rectangular frame, which saves time and improves the installation efficiency of the mineral wool board.

[0036] 2. The lever design eliminates the need for staff to manually move the fixed lever, providing convenience for their work.

[0037] 3. The third spring always exerts a downward force on the clamping plate, which enables the clamping plate and the support plate to clamp and fix the mineral wool board, thus improving the stability of the mineral wool board fixation. Attached Figure Description

[0044] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0045] This application discloses a mineral wool board ceiling.

[0046] refer to Figure 1 A mineral wool board ceiling is suitable for roof 1. Multiple hangers 2 are fixedly connected to the lower surface of roof 1. The length direction of the hangers 2 is perpendicular to roof 1. Multiple load-bearing keels 3 are horizontally arranged below the hangers 2. The load-bearing keels 3 are connected to the bottom ends of the multiple hangers 2. The load-bearing keels 3 are perpendicular to the hangers 2 and parallel to each other. Multiple main keels 4 are horizontally arranged below the load-bearing keels 3. The main keels 4 are fixedly connected to the load-bearing keels 3 and the length direction of the main keels 4 is perpendicular to the load-bearing keels 3. Side keels 9 are horizontally arranged at the ends of the main keels 4. The length direction of the side keels 9 is perpendicular to the length direction of the main keels 4. Multiple secondary keels 5 are connected below the main keels 4. The length direction of the secondary keels 5 is perpendicular to the main keels 4 and parallel to each other.

[0047] refer to Figure 1 and Figure 2 Multiple threaded sleeves 31 are rotatably connected to the upper surface of the supporting keel 3. The length direction of the multiple threaded sleeves 31 is perpendicular to the length direction of the hanger 2. The multiple threaded sleeves 31 are arranged sequentially along the length direction of the supporting keel 3. The threaded sleeves 31 are threadedly connected to the bottom end of the hanger 2 and correspond one-to-one. When fixing the supporting keel 3, the threaded sleeves 31 and the hanger 2 are aligned. Rotating the threaded sleeves 31 connects the threaded sleeves 31 to the bottom end of the hanger 2 and drives the supporting keel 3 to move upward. By adjusting the connection length between individual threaded sleeves 31 and the hanger 2, the supporting keel 3 can be kept in a horizontal state.

[0048] refer to Figure 1 , Figure 3 and Figure 4The lower surface of the main keel 4 is provided with multiple first connecting grooves 41, which are arranged sequentially along the length of the main keel 4. The first connecting grooves 41 penetrate through the opposite sides of the main keel 4. The first connecting grooves 41 and the secondary keel 5 are engaged and adapted. The main keel 4 is provided with moving grooves 42 on the opposite side walls of the first connecting grooves 41. The moving grooves 42 are provided with connecting components 7 for connecting with the secondary keel 5. The upper surface of the secondary keel 5 is provided with multiple second connecting grooves 59, which are arranged sequentially along the length of the secondary keel 5. The second connecting grooves 59 penetrate through the opposite sides of the secondary keel 5. The second connecting grooves 59 and the main keel 4 are engaged and adapted. The first connecting grooves 41 and the second connecting grooves 59 correspond one-to-one.

[0049] Multiple slots 8 are provided on both sides of the secondary keel 5. The multiple slots 8 are arranged sequentially along the length of the secondary keel 5. The connecting component 7 includes a locking block 71 and a fourth spring 72. The locking block 71 is set in the moving groove 42. The locking block 71 and the main keel 4 are slidably connected. The locking block 71 and the slot 8 are locked and matched one by one. The fourth spring 72 is fixed between the locking block 71 and the bottom wall of the moving groove 42. The side of the locking block 71 away from the fourth spring 72 is set as an inclined surface. The inclined surface is set from top to bottom along the direction towards the fourth spring 72.

[0050] When the secondary keel 5 and the main keel 4 are connected, the second connecting groove 59 of the secondary keel 5 is aligned with the first connecting groove 41 of the main keel 4. The secondary keel 5 is moved upward. The secondary keel 5 first abuts against the inclined surface of the locking block 71 and pushes the locking block 71 to move into the moving groove 42. The fourth spring 72 is compressed. When the bottom wall of the second connecting groove 59 of the secondary keel 5 abuts against the bottom wall of the first connecting groove 41 of the main keel 4, the fourth spring 72 releases its elastic force and pushes the locking block 71 to move towards the locking groove 8. The end of the locking block 71 away from the fourth spring 72 moves into the locking groove 8, and the locking block 71 and the secondary keel 5 are locked together and fixed, thus realizing the locking and fixing of the main keel 4 and the secondary keel 5.

[0051] refer to Figure 1 and Figure 5 The secondary keel 5 has a mounting groove 52 on both sides. A support plate 53 is slidably connected to the secondary keel 5 in the mounting groove 52. A first spring 54 is fixed between the support plate 53 and the bottom wall of the mounting groove 52. A sliding groove 56 is opened on both sides of the secondary keel 5 in the vertical direction. The sliding groove 56 is located directly above the mounting groove 52. A slider 561 is slidably connected to the secondary keel 5 in the sliding groove 56. A third spring 57 is fixed between the slider 561 and the top wall of the sliding groove 56. A clamping plate 51 is fixedly connected to the side of the slider 561 away from the bottom wall of the sliding groove 56. The clamping plate 51 is horizontally set and its length direction is parallel to the length direction of the secondary keel 5.

[0052] The mineral wool board is moved horizontally within the rectangular area enclosed by the main keel 4 and the secondary keel 5. During the movement of the mineral wool board, the support plate 53 moves into the placement groove 52, and the first spring 54 is compressed. Then, the mineral wool board and the clamping plate 51 come into contact, pushing the clamping plate 51 upward. The clamping plate 51 drives the slider 561 to move, and the third spring 57 is compressed. When the mineral wool board moves above the support plate 53, the first spring 54 releases its elastic force to push the support plate 53 outward. The upper surface of the support plate 53 comes into contact with the lower surface of the mineral wool board. At the same time, the third spring 57 always exerts a downward force on the slider 561, so that the clamping plate 51 and the support plate 53 complete the clamping and fixing of the mineral wool board, thus completing the installation of the mineral wool.

[0053] refer to Figure 1 and Figure 5 The secondary keel 5 has two cavities 55 vertically arranged inside. The bottom of the cavity 55 is connected to the mounting groove 52 and they correspond one-to-one. The cavity 55 is provided with a fixing component 6 for fixing the support plate 53. The upper surface of the support plate 53 near the first spring 54 has a first fixing groove 531 and a second fixing groove 532. The first fixing groove 531 is located on the side of the second fixing groove 532 away from the first spring 54. The fixing component 6 includes a fixing rod 61 and a second spring 62. The fixing rod 61 is arranged in the cavity 55 and slidably connected to the secondary keel 5. The length direction of the fixing rod 61 is perpendicular to the length direction of the secondary keel 5. The fixing rod 61 and the first fixing groove 531 are inserted and matched, and the fixing rod 61 and the second fixing groove 532 are inserted and matched. The second spring 62 is fixed between the fixing rod 61 and the top wall of the cavity 55. The elastic force of the second spring 62 is less than the elastic force of the third spring 57.

[0054] The slide groove 56 and the cavity 55 are connected at the upper end. The secondary keel 5 is slidably connected to the lever 58 at the connection between the slide groove 56 and the cavity 55. The lever 58 is inclined from top to bottom towards the fixed rod 61 on the side near the fixed rod 61. The fixed rod 61 has a lever groove 611 on the side facing the lever 58. The lever 58 and the lever groove 611 are plugged into each other. The slider 561 has an avoidance groove 562 on the side away from the clamp 51. The lever 58 is inclined from the middle towards the upper and lower sides on the side away from the fixed rod 61.

[0055] When the mineral wool board is not placed, the support plate 53 is in the placement groove 52, the first spring 54 is in a compressed state, and the bottom end of the fixing rod 61 extends into the first fixing groove 531 to fix the support plate 53. As the mineral wool board pushes the clamping plate 51 upward, the clamping plate 51 drives the slider 561 to move. The slider 561 first abuts against the inclined surface of the end of the lever 58 away from the fixing rod 61, and pushes the lever 58 towards the fixing rod 61. The end of the lever 58 near the fixing rod 61 gradually extends into the lever groove 611, and... When the fixed rod 61 moves upward, the second spring 62 is compressed, and the bottom end of the fixed rod 61 moves out of the first fixed groove 531. The first spring 54 releases its elastic force, pushing the tray 53 to move outward. At this time, the lever 58 and the clearance groove 562 are aligned. The second spring 62 releases its elastic force, pushing the fixed rod 61 downward and pushing the lever 58 to move into the clearance groove 562. The bottom end of the fixed rod 61 extends into the second fixed groove 532, thus fixing the tray 53 and making it difficult for the tray 53 to move into the placement groove 52.

[0056] The implementation principle of a mineral wool board ceiling according to an embodiment of this application is as follows: the mineral wool board is moved horizontally upward. The mineral wool board first contacts the clamping plate 51 and pushes the clamping plate 51 to move upward. The third spring 57 is compressed, the clamping plate 51 drives the slider 561 to move, and the slider 561 drives the lever 58 to move, so that the fixing component 6 releases the fixation of the support plate 53. The first spring 54 releases its elastic force and pushes the support plate 53 to move out of the placement groove 52. The support plate 53 supports the mineral wool board. At the same time, the fixing component 6 fixes the support plate 53 again, so that the support plate 53 is not easy to move into the placement groove 52. The clamping plate 51 is always subjected to a downward force from the third spring 57, so that the clamping plate 51 and the support plate 53 clamp and fix the mineral wool board, thus completing the installation of the mineral wool board. It is not necessary to first pass it vertically through the rectangular frame and then place the mineral wool board horizontally in the rectangular frame, saving time and improving the installation efficiency of the mineral wool board.

[0062] S3. Move the load-bearing keel 3 so that the threaded sleeve 31 and the bottom end of the hanger 2 are aligned. Rotate the threaded sleeve 31 to connect the threaded sleeve 31 and the hanger 2, thus connecting the load-bearing keel 3 and the hanger 2. By rotating the threaded sleeve 31, adjust the connection length between the threaded sleeve 31 and the hanger 2, and adjust the multiple load-bearing keels 3 to be neat and consistent in elevation.

[0063] S4. Install the main keel 4 on the lower surface of the load-bearing keel 3, and fix the side keel 9 with cement nails around the wall according to the elevation line on the wall. The end of the main keel 4 is connected to the side keel 9 and fixed.
