[0001] This utility model relates to the field of grooving technology for aerated concrete blocks, specifically a grooving tool for wall reinforcement bars in aerated concrete blocks. Background Technology
[0002] A Chinese patent document with publication number CN220922904U discloses a grooving device for aerated concrete blocks, comprising a workbench with a grooving device body inside. Two upright plates are fixed to the top of the workbench, and an adjustment assembly is installed inside each upright plate. The adjustment assembly includes a toothed plate fixed to one opposite wall of the inner cavity of the two upright plates, and a movable block slidably connected to the inside of the two upright plates. A micro motor is fixed inside the movable block, and a rotating rod is fixed to the output end of the micro motor. A gear is fixed to the outer surface of the rotating rod. Narrow plates are fixed to both the upper and lower ends of the movable block. This grooving device for aerated concrete blocks, by incorporating the adjustment assembly, can be adjusted according to the required grooving depth and the grooving depth required for blocks of different sizes, effectively improving the accuracy of grooving and clamping and fixing the blocks, thereby increasing the safety factor during grooving.
[0003] The existing technology lacks adjustable-width grooving tools, and construction workers often need to prepare multiple sizes of equipment or make complex modifications to the same tool. This not only reduces construction efficiency but also increases equipment procurement and maintenance costs, and may also affect the grooving quality due to poor tool compatibility.
[0004] Therefore, this utility model proposes a groove-cutting tool for aerated concrete block wall reinforcement to solve the above problems. Utility Model Content

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Example 1: Please refer to Figures 1-2 A grooving tool for aerated concrete block wall reinforcement includes a tool body 1, a handle 2, and a grooving head 3. The handle 2 is fixedly installed at the top of the tool body 1, and the grooving head 3 is installed at one end of the tool body 1. The tool body 1 is installed on an aerated concrete block 4. The grooving head 3 is provided with an adjustment component 5, a snap-fit component 6, and a fixing component 7. The adjustment component 5 is installed at the other end of the grooving head 3, the snap-fit component 6 is installed on the adjustment component 5, and the fixing component 7 is installed on the snap-fit component 6.
[0021] The top of the adjusting plate 501 in the adjusting assembly 5 is provided with a sliding protrusion 505, and the end of the adjusting plate 501 is fixedly provided with a sliding plate 502.
[0022] When using it, the construction workers first determine the required groove width according to the design specifications of the wall reinforcement bars on the aerated concrete block 4. Then, they hold the sliding protrusion 505 and apply force smoothly along the adjustment direction of the groove head 3. At this time, the adjustment plate 501 moves under the action of force, which drives the sliding plate 502 at the end to slide synchronously in the sliding groove 504 inside the groove head 3. With just a simple push and pull operation, the groove requirements of different projects can be quickly responded to, which greatly saves the preparation time before construction.
[0023] Example 2: Based on Example 1, please refer to... Figures 2-3 In the adjustment component 5, a limiting plate 503 is fixedly provided at the end of the sliding plate 502. The sliding plate 502 is adapted to slide and fit into the sliding groove 504, which is located in the slotted head 3.
[0024] The snap-fit rod 601 in the snap-fit assembly 6 is fixedly installed at the bottom end of the sliding plate 502. The snap-fit rod 601 is slidably snapped into the second snap-fit groove 602, which is located at the bottom end of the sliding groove 504.
[0025] In use, after adjusting the grooving width using the adjusting plate 501, the limiting plate 503 at the end of the sliding plate 502 ensures that it will not slide out of the sliding groove 504. At this time, the locking rod 601 at the bottom of the sliding plate 502 is inserted into the second locking groove 602 at the bottom of the sliding groove 504 to initially position and fix the adjusted sliding plate 502, so that the grooving head 3 remains stable in subsequent operations, preventing the width from changing due to slight shaking, and ensuring that the grooving operation is carried out in an orderly manner.
[0026] Example 3: Based on Example 2, please refer to... Figures 3-4The positioning holes 701 in the fixing component 7 are evenly arranged at the top end of the slotted head 3, and the positioning holes 701 and the fixing holes 702 are fixedly connected by connecting screws 703.
[0027] The fixing hole 702 in the fixing component 7 is provided on the sliding plate 502, and the top of the connecting screw 703 is provided with a connecting plate 704. The connecting screw 703 is fixed by bolts.
[0028] In use, after the snap-fit assembly 6 has completed its initial positioning, the construction personnel take out the connecting screw 703 and accurately pass it through the evenly distributed positioning holes 701 on the top of the slotted head 3 and the corresponding fixing holes 702 on the sliding plate 502. Then, using the matching screwdriver or wrench, the bolts at the top of the connecting screw 703 are tightened. As the bolts are gradually tightened, the connecting plate 704 at the top of the connecting screw 703 is slowly pressed down, using a strong clamping force to tightly fit the sliding plate 502 and the slotted head 3 together. This fixing method using screws can generate a continuous and stable clamping force. Even when facing high-intensity, long-term slotting operations and the irregular resistance brought by the aerated concrete block 4 material, it can ensure that the slotted head 3 always maintains a fixed width, effectively preventing displacement or loosening during the slotting process, and improving the overall construction quality and efficiency.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
