Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of masonry scraper devices, in particular to a mortar scraping device for aerated concrete block masonry. Background Art
[0002] Aerated concrete blocks are a new type of building material that is lightweight, porous, heat-insulating, seismic-insulating, sound-insulating, energy-saving and environmentally friendly. It uses cement, lime, silica sand and other materials as the main raw materials, and is mixed with aluminum powder as an aerating agent. It is a porous concrete product made through grinding, metering, mixing, pouring, gas expansion, static maintenance, cutting and other processes. Because it has a large number of pores and micropores inside, it has excellent thermal insulation performance, low thermal conductivity and high thermal resistance. At the same time, aerated concrete blocks also have good seismic resistance, fire resistance and sound insulation performance, which can effectively improve the overall performance of buildings. Aerated concrete blocks are widely used in various types of buildings. In the construction of internal and external wall filling, partition walls, floor slabs and roof panels, compared with traditional solid clay bricks, aerated concrete blocks have lighter weight, higher strength, better thermal insulation performance and lower cost. Therefore, the use of aerated concrete blocks can effectively reduce the weight of the building, improve construction efficiency, reduce construction costs, and also help energy conservation, emission reduction and environmental protection.
[0003] When laying aerated concrete blocks, the necessity of evenly applying the mortar cannot be ignored. As the adhesive between the blocks, the even application of the mortar is directly related to the overall strength and stability of the wall. If the mortar is not evenly applied, the bonding layer between the blocks will be of different thicknesses, which will not only weaken the load-bearing capacity of the wall, but may also cause cracking, deformation and other quality problems during the use of the wall. In addition, evenly applying the mortar can also ensure the flatness and beauty of the block surface and improve the overall quality of the wall. Therefore, when laying aerated concrete blocks, attention must be paid to the quality of the mortar scraping to ensure that the mortar can evenly cover the block surface and has a moderate thickness. This is not only a guarantee of wall performance and service life, but also a responsible attitude towards building quality and safety. At the same time, operators should also have professional skills and rich experience to ensure the accuracy and efficiency of the mortar scraping. Utility Model Content
[0004] (I) Technical problems to be solved: In view of the deficiencies in the prior art, the utility model provides a mortar scraping device for aerated concrete block masonry, which has the advantage of being able to evenly scrape the mortar, thus solving the problem of uneven mortar application during masonry.
[0005] (ii) Technical solution: In order to achieve the above-mentioned purpose of being able to evenly scrape mortar, the utility model provides the following technical solution: a device for scraping mortar evenly for aerated concrete block masonry, comprising a handle, a U-shaped scraper head and a scraper, the handle being connected to the closed end of the scraper head, notches and balancing components being provided on both sides of the scraper head, and a connecting rod being provided in the notch, a scraper being fixed on the connecting rod, and the diameters of the two ends of the scraper being larger than the diameter of the middle section, the scraper being able to translate and rotate with the connecting rod, the balancing component being closer to the handle than the notch, the balancing component being connected to the two ends of the connecting rod by a push rod, when the scraper is tilted during operation, driving the connecting rod to tilt, the balancing component at the tilted end will generate a greater reaction force than the other end, making the scraper parallel.
[0006] Preferably, the balancing assembly consists of an airbag and two permanent magnets of the same magnetic property, the airbag is arranged between the two permanent magnets, one of the permanent magnets is fixed inside the balancing assembly, and the other is connected to the push rod and can move inside the balancing assembly so that the airbag is compressed.
[0007] Preferably, a window is provided on the surface of the balancing component, through which the expansion of the airbag can be observed, and the airbag is filled with colored gas. Workers can quickly judge the approximate thickness of the mortar by the expansion of the airbag and the change in color depth, and make adjustments during the scraping process.
[0008] Preferably, the handle and the scraper head are movably connected. Different operating angles and forces may be required in different masonry operations. By adjusting the position and angle of the handle, the operator can better adapt to these changes and achieve more precise and efficient operations.
[0009] Preferably, the scraper surface is provided with serrated patterns. The design of the serrated patterns helps to form a more uniform scraping slurry layer during the scraping process. Due to the presence of the patterns, the scraper can better disperse and distribute the slurry to avoid uneven thickness during the scraping process. The serrated patterns increase the contact area between the scraper and the scraping slurry, thereby improving the adhesion and gripping ability of the scraping slurry. This makes the scraper more effective in scraping off excess slurry, can more thoroughly remove the scraping slurry, and reduce the residue of slurry on the scraper.
[0010] (III) Beneficial effects: Compared with the prior art, the utility model provides a mortar scraping device for aerated concrete block masonry, which has the following beneficial effects:
[0011] 1. The mortar-scraping device for aerated concrete block masonry uses the repulsive force between two permanent magnets with the same magnetic properties. When the scraper tilts due to encountering thicker slurry, the two permanent magnets on the tilted side will repel each other due to the shortened distance. This repulsive force is a dynamic process. It will increase with the increase of the scraper tilt angle, thereby forming a self-correction mechanism. This mechanism can quickly and effectively adjust the scraper back to a horizontal state to prevent uneven slurry caused by tilting. When the permanent magnets repel each other, they will squeeze the airbag to compress the gas in the airbag. The reaction force generated by this compression will help the scraper to return to a balanced state faster. The elasticity of the airbag can also absorb the vibration and impact during the movement of the scraper to a certain extent, making the movement of the scraper more stable and further improving the uniformity of the slurry. Since the scraper can automatically adjust the angle and maintain the uniformity of the slurry, the frequency and difficulty of manual adjustment of the scraper can be greatly reduced. At the same time, since the movement of the scraper is more stable, the problems of block dislocation and wall cracking caused by uneven slurry can also be reduced, thereby improving the overall performance of the wall.
[0012] 2. The mortar scraping device for aerated concrete block masonry is provided with a window on the surface of the balance component, through which the expansion of the airbag can be observed, and the airbag is filled with colored gas. Workers can quickly judge the approximate thickness of the mortar by the expansion of the airbag and the change in color depth, and make adjustments during the scraping process. The handle and the scraper head are movably connected. Different operating angles and forces may be required in different masonry work. By adjusting the position and angle of the handle, the operator can better adapt to these changes and achieve more accurate and efficient operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1 A device for scraping mortar for aerated concrete block masonry comprises a handle 1, a U-shaped scraper head 2 and a scraper 212, wherein the handle 1 is connected to the closed end of the scraper head 2, notches 21 and balancing components 22 are provided on both sides of the scraper head 2, and a connecting rod 211 is provided in the notch 21, a scraper 212 is fixed on the connecting rod 211, and the diameters of the two ends of the scraper 212 are larger than the diameter of the middle section, the scraper 212 can translate and rotate with the connecting rod 211, the balancing component 22 is closer to the handle 1 than the notch 21, and the balancing component 22 is connected to the two ends of the connecting rod 211 through a push rod 201, when the scraper 212 is tilted during operation, driving the connecting rod 211 to tilt, the balancing component 22 at the tilted end will generate a greater reaction force than the other end, so that the scraper 212 is parallel.
[0018] For further information, see Figure 2 The balancing component 22 is composed of an airbag 222 and two permanent magnets 221 of the same magnetic property. The airbag 222 is arranged between the two permanent magnets 221. One of the permanent magnets 221 is fixed inside the balancing component 22, and the other is connected to the push rod 201 and can move inside the balancing component 22, so that the airbag 222 is compressed, and the scraper 212 is tilted, so that the end of the connecting rod 211 moves upward in the notch 21 on the corresponding side, driving the push rod 201 to push the connected permanent magnet 221 upward. Because the balancing component 22 is also provided with a permanent magnet 221 of the same magnetic property, and There are air bags in the two permanent magnets 221. The two permanent magnets 221 on the inclined side will repel each other due to the shortened distance. This repulsive force is a dynamic process. It will increase as the inclination angle of the scraper 212 increases, thereby forming a self-correction mechanism. This mechanism can quickly and effectively adjust the scraper 212 back to a horizontal state to prevent uneven scraping due to inclination. When the permanent magnets 221 repel each other, they will squeeze the air bags 222, compressing the gas in the air bags 222. The reaction force generated by this compression will help the scraper 212 to return to a balanced state faster.
[0019] A window is provided on the surface of the balancing component 22, through which the expansion of the airbag 222 can be observed. The airbag 222 is filled with colored gas. Workers can quickly judge the approximate thickness of the mortar by the expansion of the airbag 222 and the change in color depth, and make adjustments during the scraping process.
[0020] The handle 1 and the scraper head 2 are movably connected. Different operating angles and forces may be required in different masonry operations. By adjusting the position and angle of the handle 1, the operator can better adapt to these changes and achieve more precise and efficient operations.
[0021] The scraper 212 has serrated patterns on its surface. The serrated patterns help to form a more uniform slurry layer during the scraping process. Due to the patterns, the scraper can better disperse and distribute the slurry to avoid uneven thickness during the scraping process. The serrated patterns increase the contact area between the scraper and the slurry, thereby improving the adhesion and gripping ability of the slurry. This makes the scraper more effective in scraping off excess slurry, and can more thoroughly remove the slurry, reducing the residue of slurry on the scraper.
[0022] Working principle: When workers are laying aerated concrete blocks, after surface treatment of the blocks, they prepare an appropriate amount of slurry to ensure that its quality and performance meet the construction requirements. Then, mortar is applied on the top of the blocks. The workers hold the handle 1 and use a scraper to evenly apply the mortar. When the mortar thickness on the top of the blocks is uneven, one side is thicker, which will cause the scraper 212 to tilt. The scraper 212 tilts, causing the end of the connecting rod 211 to move upward in the groove 21 on the corresponding side, driving the push rod 201 to push the connected permanent magnet 221 upward, because the balance component 22 is also provided with a permanent magnet 221 with the same magnetic property, and There are air bags in the two permanent magnets 221. The two permanent magnets 221 on the inclined side will repel each other due to the shortened distance. This repulsive force is a dynamic process. It will increase as the inclination angle of the scraper 212 increases, thereby forming a self-correction mechanism. This mechanism can quickly and effectively adjust the scraper 212 back to a horizontal state to prevent uneven scraping due to inclination. When the permanent magnets 221 repel each other, they will squeeze the air bags 222, compressing the gas in the air bags 222. The reaction force generated by this compression will help the scraper 212 to return to a balanced state faster.
