Description

Technical Field

[0001] This utility model relates to the field of autoclaved aerated concrete (AAC) panels, and more particularly to an AAC panel that can be installed quickly. Background Technology

[0002] Autoclaved aerated concrete (AAC) panels are lightweight, porous precast panels primarily composed of siliceous and calcareous materials, with aluminum powder added as a gas-generating agent. Furthermore, these panels are typically reinforced with rust-resistant steel mesh and are manufactured through processes including batching and casting, gas generation and static curing, cutting, and autoclaving. AAC panels can be used for building exterior walls, partitions, roof panels, and floor slabs.

[0003] In existing technologies, when multiple autoclaved aerated concrete (AAC) wall panels are assembled together, the sides of the panels are spliced ​​together, and an adhesive is applied to the joints to improve the bonding strength between the AAC panels. However, due to issues such as the size or weight of the AAC wall panels, it is impossible to guarantee that they will make proper contact after splicing, and misalignment may occur, resulting in insufficient bonding strength. Therefore, we propose a quick-installation AAC panel to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fast-installing autoclaved aerated concrete panel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-installation autoclaved aerated concrete (AAC) slab includes a first slab body and a second slab body. A butt joint strip is fixedly connected to the outer walls of both the first and second slab bodies. A butt joint groove is formed on the outer walls of both the first and second slab bodies. Four grooves are formed on the outer walls of both the first and second slab bodies. A U-shaped component is slidably fitted onto the inner walls of two of the grooves. Two gaskets are welded to the outer walls of the U-shaped component. Circular holes are formed on the outer walls of the gaskets. Two assembly holes are formed on the outer walls of both the first and second slab bodies. Threaded rods are slidably connected to the inner walls of the assembly holes. A butt joint mechanism is provided on the outer walls of the threaded rods.

[0007] Preferably, the docking mechanism includes two nuts, the outer wall of the threaded rod is threadedly connected to the inner wall of the two nuts, and two docking pieces are slidably sleeved on the outer wall of the threaded rod. The outer wall of the docking pieces has two through holes, and the inner wall of the two through holes is threadedly connected to the same bolt. By setting the threaded rod and nuts, the two docking pieces are fixed on the outer wall of the first concrete slab body and the second concrete slab body to facilitate subsequent installation.

[0008] Preferably, each of the four grooves is provided with a through hole in pairs. The through holes and the round holes are used in conjunction to fix the U-shaped piece to the outer wall of the first concrete slab body and the second concrete slab body after the bolt is slid in.

[0009] Preferably, the connecting strip and the connecting groove cooperate to facilitate the connection and installation, and to avoid misalignment during installation.

[0010] Preferably, the outer walls of the plurality of nuts are respectively pressed against the outer walls of the first concrete slab body and the second concrete slab body.

[0011] Preferably, the outer wall of the gasket is slidably connected to the inner wall of the groove, and the U-shaped piece is pre-clamped onto the outer walls of the first concrete slab body and the second concrete slab body through the gasket.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution increases overall connectivity and prevents subsequent misalignment by setting up connecting strips, connecting grooves, recesses, through holes, assembly holes, U-shaped parts, gaskets, round holes, threaded rods, nuts, connecting pieces, and bolts. At the same time, it further increases the overall connection strength, allowing the adhesive in the connecting groove to better contact the connecting strip and the outer wall of the first concrete slab, forming a better bonding effect.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1-4 As shown, a quick-installation autoclaved aerated concrete (AAC) slab is disclosed, comprising a first concrete slab body 1 and a second concrete slab body 2. The first concrete slab body 1 and the second concrete slab body 2 are each fixedly connected to an interlocking strip 3. Both the first concrete slab body 1 and the second concrete slab body 2 have interlocking grooves 4 on their outer walls. The interlocking strip 3 engages with the interlocking grooves 4, sliding into the interlocking grooves 4 to connect the first concrete slab body 1 and the second concrete slab body 2.

[0022] The outer walls of both the first concrete slab body 1 and the second concrete slab body 2 are provided with four grooves 5. Each of the four grooves 5 is provided with a through hole 6 in pairs. The through hole 6 is used for the subsequent insertion of bolts 14. The inner walls of the two grooves 5 are slidably fitted with the same U-shaped piece 8. The outer walls of the U-shaped piece 8 are welded with two gaskets 9. The outer walls of the gaskets 9 are slidably connected to the inner walls of the grooves 5. The U-shaped piece 8 slides into the grooves 5 through the two gaskets 9. The U-shaped piece 8 is limited in the grooves 5 by the extrusion force.

[0023] The outer wall of the gasket 9 has a round hole 10. The outer walls of the first concrete slab body 1 and the second concrete slab body 2 each have two assembly holes 7. The inner walls of the multiple assembly holes 7 are slidably connected with threaded rods 11. The threaded rods 11 slide into the assembly holes 7 and are fixed in position with two nuts 12. This also drives the two mating pieces 13 to be fixed in the appropriate position. Subsequently, the mating pieces 13 will slide into the groove 5 onto the outer wall of the gasket 9.

[0024] The outer wall of the threaded rod 11 is provided with a docking mechanism, which includes two nuts 12. The outer walls of the multiple nuts 12 are respectively pressed against the outer walls of the first concrete slab body 1 and the second concrete slab body 2. The outer wall of the threaded rod 11 is threadedly connected to the inner walls of the two nuts 12. The outer wall of the threaded rod 11 is slidably fitted with two docking pieces 13. The outer wall of the docking pieces 13 has two through holes. The inner walls of the two through holes are threadedly connected to the same bolt 14. The bolt 14 is screwed into the through hole and the round hole 10, so that the U-shaped piece 8 is fixed on the outer walls of the first concrete slab body 1 and the second concrete slab body 2, and the connection between the first concrete slab body 1 and the second concrete slab body 2 is increased.

[0025] Working principle: When assembling the first concrete slab body 1 and the second concrete slab body 2, firstly, the first concrete slab body 1 and the second concrete slab body 2 are erected to form a side splice. Adhesive is applied to the inner wall of the mating groove 4 and the outer wall of the second concrete slab body 2. Then, the first concrete slab body 1 is moved closer to the second concrete slab body 2, so that the mating strip 3 slides into the mating groove 4 to form an adhesive process. At this time, the upper and lower U-shaped parts 8 of the first concrete slab body 1 slide into the outer wall of the second concrete slab body 2 to increase the overall connection and prevent subsequent misalignment. At the same time, the mating pieces 13 slide into the outer walls of multiple gaskets 9 respectively. After the through holes and round holes 10 on the mating pieces 13 are interconnected, the bolts 14 are screwed into the through holes and round holes 10, so that the first concrete slab body 1 moves towards the second concrete slab body 2 to make them contact each other, further increasing the overall connection strength. At the same time, the adhesive in the mating groove 4 makes better contact with the mating strip 3 and the outer wall of the first concrete slab body 1 to form a better bonding effect. The above splicing and installation can then be carried out sequentially.
