Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a prefabricated ALC interior wall panel. Background Technology

[0002] ALC is short for autoclaved lightweight concrete, a type of high-performance autoclaved aerated concrete. ALC boards are made from fly ash (or silica sand), cement, lime, and other main raw materials, and are formed into multi-porous concrete panels (containing treated steel reinforcement) through high-pressure steam curing. ALC boards can be used as wall materials or roof panels, and are a new type of building material with superior performance.

[0003] Existing ALC wall panels typically require U-shaped clips to be installed on the top of the installation location before the ALC wall panels are inserted into the U-shaped clips. However, the gap between the ALC wall panels and the ceiling is relatively large and difficult to minimize, resulting in weak installation stability of the ALC wall panels. To address these issues, the existing equipment needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated ALC interior wall panel to solve the problem mentioned in the background art that existing ALC wall panels generally require a U-shaped buckle to be installed on the top of the installation location before installation, and then the ALC wall panel is embedded in the U-shaped buckle. The gap between the ALC wall panel and the ceiling is large and it is difficult to minimize the gap as much as possible, resulting in poor installation stability of the ALC wall panel.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated ALC interior wall panel, comprising an ALC wall panel, a protruding strip fixed on one side of the ALC wall panel, a first groove formed on the other side of the ALC wall panel, a second groove formed on the top of the ALC wall panel, a pressing and locking mechanism provided in the second groove, the pressing and locking mechanism comprising a pipe, a pressing block fixed on the top of the pipe, a third groove formed on the bottom of the pipe, a first compression spring fixed in the third groove, a sealing plate fixed on the bottom of the first compression spring, an auxiliary positioning mechanism engaged with the outer side of one end of the pipe, and a fastening plate fastened to the outer side of the pipe.

[0006] A top plate is placed in the second groove, and the top plate rests on the buckle plate. A movable block is fixed at the bottom of the top plate. The movable block is wedge-shaped and fitted to one side of the extrusion block. A hydraulic channel is opened in the ALC wall panel, and the hydraulic channel is connected to the bottom of the second groove.

[0007] Preferably, one end of the pipe has an annular groove, and the other end of the pipe is fixed with a sealing ring.

[0008] Preferably, the extrusion blocks are evenly distributed on the pipe, and the extrusion blocks and the movable blocks are arranged in a one-to-one correspondence.

[0009] Preferably, a top support rod is fixed inside the pipe, and the top support rods are evenly distributed on the pipe.

[0010] Preferably, the top and bottom of the pipe are provided with slots, and the bottom of the pipe is provided with a first through hole.

[0011] Preferably, the auxiliary positioning mechanism includes a positioning frame, which is fitted onto the outside of one end of the pipe. The positioning frame has symmetrically arranged fourth grooves on both sides. A gear is rotatably connected in the fourth groove, and a first toothed plate is meshed with one side of the gear. The first toothed plate is connected to the positioning frame through a second compression spring, and the first toothed plate penetrates the outer wall of the positioning frame and is connected to a pressing block. A second toothed plate is meshed with the other side of the gear, and the second toothed plate penetrates the inner wall of the positioning frame and is engaged in a slot.

[0012] Preferably, the top of the buckle plate is provided with a second through hole, and both the pressing block and the movable block extend into the second through hole. Limiting grooves are symmetrically provided on both sides of the buckle plate.

[0013] Preferably, a piston is slidably connected to the end of the hydraulic channel, and support columns are symmetrically fixed on both sides of the upper surface of the piston, the support columns being slidably connected in the limiting groove.

[0014] Preferably, a third compression spring is symmetrically fixed on the two inner walls at the first end of the hydraulic channel, and a locking block is fixed to the inner end of the third compression spring. A bracket is fixed at the first end of the hydraulic channel, and a sealing block is fixed to the upper end face of the bracket.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This prefabricated ALC interior wall panel can reduce gaps. When splicing multiple ALC wall panels together, the protruding strip needs to be inserted into the first groove. Multiple pipes can be clamped together by the action of the annular groove and sealing ring. After completing the splicing and installation of all ALC wall panels, a positioning frame can be installed on the outside of the last pipe. Then, tap the pipe to the left, and all the pipes will move to the left. The extrusion block will press the movable block and the top plate upward, and the top plate will be close to the ceiling, which can reduce the gap between the ALC wall panel and the ceiling.

[0017] 2. This prefabricated ALC interior wall panel can achieve the purpose of top support and locking. When the top plate is moved up by tapping the pipe, when the positioning frame moves to the left to the bottom, it means that the top plate has moved up to the top. At this time, the first through hole is completely aligned with the hydraulic channel. When hydraulic oil is injected into the pipe, the hydraulic oil enters the hydraulic channel, the piston and support column move up and support the top plate to prevent the top plate from moving back. After removing the positioning frame, continue to tap the pipe to the left and make the third groove align with the hydraulic channel. The sealing plate automatically pops into the hydraulic channel, the sealing block seals the hole on the sealing plate, the sealing plate seals the hydraulic channel, and the piston and support column are fixed.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 7 The present invention provides a technical solution: a prefabricated ALC interior wall panel, including an ALC wall panel 1, a protruding strip 2 fixed on one side of the ALC wall panel 1, a first groove 3 opened on the other side of the ALC wall panel 1, a second groove 4 opened on the top of the ALC wall panel 1, a pressing and locking mechanism 5 provided in the second groove 4, the pressing and locking mechanism 5 including a pipe 501, a pressing block 504 fixed on the top of the pipe 501, a third groove 508 opened on the bottom of the pipe 501, a first compression spring 509 fixed in the third groove 508, a sealing plate 510 fixed on the bottom of the first compression spring 509, an auxiliary positioning mechanism 6 engaged with the outer side of one end of the pipe 501, and a buckle plate 7 fastened to the outer side of the pipe 501.

[0028] A top plate 10 is placed inside the second groove 4. The top plate 10 rests on the buckle plate 7. A movable block 11 is fixed to the bottom of the top plate 10. The movable block 11 is wedge-shaped and connected to one side of the extrusion block 504. A hydraulic channel 14 is opened inside the ALC wall panel 1. The hydraulic channel 14 is connected to the bottom of the second groove 4.

[0029] In this embodiment, as Figure 2 and Figure 4As shown, one end of the pipe 501 has an annular groove 502, and the other end of the pipe 501 is fixed with a sealing ring 503. When multiple ALC wall panels 1 are spliced ​​together, the sealing ring 503 needs to be engaged and connected in the annular groove 502 to facilitate the connection of two adjacent pipes 501 together.

[0030] In this embodiment, as Figure 2 , Figure 4 and Figure 5 As shown, the extrusion blocks 504 are evenly distributed on the pipe 501, and the extrusion blocks 504 are set in a one-to-one correspondence with the movable blocks 11. When the pipe 501 is struck to the left, the extrusion blocks 504 will move to the left along with the pipe 501, thereby extruding the movable blocks 11 and the top plate 10 upward, so that the top plate 10 can be tightly attached to the ceiling, which helps to reduce the gap between the ALC wall panel 1 and the ceiling.

[0031] In this embodiment, as Figure 4 , Figure 5 and Figure 6 As shown, a top support rod 505 is fixed inside the pipe 501, and the top support rods 505 are evenly distributed on the pipe 501. The top support rods 505 play a supporting role inside the pipe 501, which helps to increase the strength of the pipe 501.

[0032] In this embodiment, as Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the top and bottom of the pipe 501 are provided with slots 506, and the bottom of the pipe 501 is provided with a first through hole 507. When the pipe 501 moves to the left and the first through hole 507 is connected to the hydraulic channel 14, when hydraulic oil is pressed into the pipe 501, the hydraulic oil can pass through the first through hole 507 and be pressed into the hydraulic channel 14.

[0033] In this embodiment, as Figure 1 , Figure 4 and Figure 6As shown, the auxiliary positioning mechanism 6 includes a positioning frame 601, which is fitted onto the outer side of one end of the pipe 501. A fourth groove 602 is symmetrically formed on both sides of the positioning frame 601. A gear 603 is rotatably connected within the fourth groove 602, and a first toothed plate 604 is meshed with one side of the gear 603. The first toothed plate 604 is connected to the positioning frame 601 via a second compression spring 605, and penetrates the outer wall of the positioning frame 601 and is connected to the pressing block 606. A second toothed plate 607 is meshed with the other side of the gear 603, and penetrates the inner wall of the positioning frame 601 and is engaged in the slot 506. When assembling multiple ALC wall panels 1 together, all pipes 501 need to be engaged and connected together to complete the assembly of multiple ALC wall panels 1. After the splicing and assembly operation, the positioning frame 601 can be placed on the outside of the last pipe 501. Pinch the two pressing blocks 606, and the first toothed plate 604 moves with the pressing blocks 606. The second toothed plate 607 moves under the rotation of the gear 603 and retracts into the fourth groove 602. After the positioning frame 601 is placed on the last pipe 501 and the second toothed plate 607 is aligned with the slot 506, release the two pressing blocks 606. The first toothed plate 604 automatically springs open under the action of the second compression spring 605. The second toothed plate 607 moves under the rotation of the gear 603 and is locked into the slot 506, which makes it easy to lock the positioning frame 601. When the positioning frame 601 moves to the left to the bottom during the process of tapping the pipe 501, it means that the first through hole 507 and the hydraulic channel 14 are aligned.

[0034] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, the top of the buckle plate 7 is provided with a second through hole 8, and the pressing block 504 and the movable block 11 both extend into the second through hole 8. The buckle plate 7 is provided with symmetrical limit grooves 9 on both sides. After the pipe 501 is placed in the second groove 4, the buckle plate 7 can be placed on the outside of the pipe 501. The buckle plate 7 plays the role of clamping and limiting the pipe 501.

[0035] In this embodiment, as Figure 4 and Figure 5 As shown, a piston 12 is slidably connected to the end of the hydraulic channel 14, and support columns 13 are symmetrically fixed on both sides of the upper surface of the piston 12. The support columns 13 are slidably connected in the limiting groove 9. When oil is pressed into the hydraulic channel 14, the piston 12 moves upward under the action of oil pressure, and the top plate 10 moves upward accordingly and lifts the top plate 10, so that the top plate 10 can be tightly attached to the ceiling.

[0036] In this embodiment, as Figure 4 and Figure 7As shown, a third compression spring 15 is symmetrically fixed on the two inner walls at the beginning of the hydraulic channel 14, and a locking block 16 is fixed to the inner end of the third compression spring 15. A bracket 17 is fixed to the beginning of the hydraulic channel 14, and a sealing block 18 is fixed to the upper end face of the bracket 17. When the pipe 501 is knocked to the left and the third groove 508 is aligned with the hydraulic channel 14, the sealing plate 510 automatically pops open and extends into the hydraulic channel 14. A small hole is opened on the sealing plate 510, and the hydraulic oil in the hydraulic channel 14 can pass through the small hole and be pressed into the third groove 508. The sealing block 18 finally seals the small hole on the sealing plate 510, and the sealing plate 510 seals the hydraulic channel 14, thus locking the piston 12 and the support column 13.

[0037] The method of use and advantages of this invention: The working process of this prefabricated ALC interior wall panel is as follows:

[0038] like Figures 1 to 7 As shown: First, place pipe 501 into the second groove 4, then place the buckle plate 7 into the second groove 4 and secure it to pipe 501. Next, place the top plate 10 into the second groove 4. Install a U-shaped clip on the top of the ALC wall panel 1 at the installation location. After installing the U-shaped clip, embed the ALC wall panel 1 into the U-shaped clip. When assembling multiple ALC wall panels 1 together, insert the protruding strip 2 into the first groove 3. Simultaneously, use the annular groove 502 and the sealing ring 503 to snap all pipes 501 together. Multiple ALC wall panels 1 are connected together using ALC-specific adhesive. The first groove 3 is half-filled with mortar. After mortar extrusion, the ALC wall panels 1 should be fixed in time. After completing the splicing and installation of all ALC wall panels 1, the positioning frame 601 is fitted onto the outer side of the last ALC wall panel corresponding to the pipe 501. The two pressing blocks 606 are pinched to fit the positioning frame 601 onto the outer side of the pipe 501 and the second toothed plate 607 is aligned with the slot 506. Then, the two pressing blocks 606 are released, and the second toothed plate 607 is aligned with the slot 506. Plate 607 automatically snaps into slot 506, thus locking positioning frame 601. Then, tapping pipe 501 to the left causes all pipes 501 to move to the left. Pressing block 606 compresses movable block 11 and top plate 10, moving them upwards so that top plate 10 is close to the ceiling, reducing the gap between ALC wall panel 1 and the ceiling. When positioning frame 601 reaches its leftmost position, it indicates that top plate 10 has moved to the top, and the first through hole 507 is perfectly aligned with hydraulic channel 14. Then, hydraulic oil is injected into pipe 501. Once inside the hydraulic channel 14, the piston 12 and support column 13 move upward under the action of oil pressure. The support column 13 supports the top plate 10 to prevent the top plate 10 from moving back. After removing the positioning frame 601, continue to knock the pipe 501 to the left and make the third groove 508 align with the hydraulic channel 14. The sealing plate 510 automatically pops into the hydraulic channel 14, and the sealing block 18 seals the hole on the sealing plate 510. The sealing plate 510 seals the hydraulic channel 14, and the piston 12 and support column 13 are locked. Finally, use ALC special sealant to seal the joint.

[0039] In summary, this prefabricated ALC interior wall panel achieves the goals of reducing gaps and locking the top support, thus meeting people's usage needs.
