Description

Technical Field

[0001] This utility model belongs to the field of building engineering, and in particular relates to an auxiliary device for plastering autoclaved aerated concrete blocks. Background Technology

[0002] Controlling the mortar joint thickness of autoclaved aerated concrete (AAC) blocks requires a certain level of operational skill, demanding a high level of expertise from workers. Many workers are unable to achieve the required mortar joint thickness, affecting the final project quality. Currently, there are some auxiliary tools for plastering thickness, but they can only control the plastering thickness based on the tool itself, and cannot monitor whether the tool is tilted or easily adjusted. If the tool is placed at an angle, it will result in uneven plastering thickness. Therefore, an adjustable plastering auxiliary device is needed. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an auxiliary device for plastering autoclaved aerated concrete blocks.

[0004] This invention is achieved through the following technical solution:

[0005] An auxiliary device for plastering autoclaved aerated concrete (AAC) blocks includes two parallel control rods. The inner sides of each control rod have several scale lines along its length. The distance between the two control rods is equal to the thickness of the AAC block. Vertical plates are provided at both ends of the control rods, and a horizontal plate is fixedly connected between the vertical plates on the same side of the two control rods. A vertical rod is provided vertically downwards at the bottom of one end of the horizontal plate, and a level is mounted on the vertical rod. Torsion springs are provided at both ends of the outer sides of the control rods, and clamping strips are connected between the two torsion springs. These clamping strips can be tightly pressed against the side of the AAC block.

[0006] Preferably, the height of the control rod is equal to the required plaster thickness.

[0007] Preferably, the clamping strip is V-shaped.

[0008] Preferably, the length of the control rod is 2-4m.

[0009] The plastering auxiliary device of this invention is adjustable to ensure the horizontality of the device, avoiding uneven plastering thickness caused by the tilt of the plastering auxiliary device. At the same time, it can effectively control the plastering thickness, requires low operator skill, is simple to operate, improves plastering quality, and increases construction efficiency.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some embodiments of the present invention, but not all embodiments.

[0015] This embodiment includes two parallel control rods 1, with the distance between the two control rods 1 equal to the thickness of the autoclaved aerated concrete (AAC) block. Mortar is applied between the two control rods 1 to form a mortar joint. Preferably, the length of the control rods 1 is 2-4m. The control rods 1 are used to control the mortar thickness. Several scale lines are provided on the inner side of the control rods 1 along their length. The mortar thickness can be controlled according to these scale lines. Since the mortar joint thickness of AAC blocks is generally required to be 15mm, it is preferable that the height of the control rods 1 is equal to the required mortar thickness, i.e., preferably 15mm. This allows the mortar to be applied directly until it is flush with the upper surface of the control rods 1.

[0016] Each control rod 1 has vertical plates 2 extending upwards at both ends. The inner side of the vertical plates 2 is flush with the inner side of the control rod 1, meaning the distance between two corresponding vertical plates 2 is equal to the thickness of the autoclaved aerated concrete block. A horizontal plate 3 is fixedly connected between the vertical plates 2 on the same side of the two control rods 1, connecting the two control rods 1 into a single unit.

[0017] A vertical rod 4 is provided vertically downward on the bottom surface of any one of the horizontal plates 3. A level 5 is provided on the vertical rod 4. The level 5 is used to test the verticality of the vertical rod 4.

[0018] Torsion springs 6 are provided at both ends of the outer side of the control rod 1. Clamping strips 7 connect the torsion springs 6 on both sides of the control rod 1. One end of each torsion spring 6 is connected to the control rod 1, and the other end is connected to the end of the clamping strip 7. Under the action of the torsion springs 6, the clamping strips 7 have a certain preload, allowing them to press tightly against the sides of the autoclaved aerated concrete block. The clamping strips 7 are similar to the clamping bars on a folder; their principle and structure will not be elaborated further here. In this embodiment, the clamping strip 7 is V-shaped.

[0019] During construction, first rotate the clamping strips 7 on both sides outward at a certain angle, place the device on the autoclaved aerated concrete block, align the bottom edge of the inner side of the control rod 1 with the edge of the upper surface of the autoclaved aerated concrete block, and make the bottom surface of the control rod 1 flush with the upper surface of the autoclaved aerated concrete block. Then loosen the clamping strips 7, and the clamping strips 7 on both sides tightly clamp the sides of the autoclaved aerated concrete block. Then observe the level 5 to see if the vertical rod 4 is in a vertical state. If the vertical rod 4 is not in a vertical state, it means that the device is tilted. At this time, rotate the clamping strips 7 outward and fine-tune the control rod 1 to make the vertical rod 4 in a vertical state. Use the clamping strips 7 again to clamp the device on the autoclaved aerated concrete block. After the device is fixed, apply mortar between the two control rods 1 until it is flush with the upper surface of the control rod 1. After completing this section, move the device to carry out the mortar joint construction of the next section. The device of this invention can make the surface of the applied mortar level, avoiding the problem of tilting, and can also correct the tilting problem of autoclaved aerated concrete blocks in a timely manner.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
