Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically to a plastering device. Background Art

[0002] Plastering is an indispensable process in building decoration projects. The straightness and squareness of the inner corners of the plastering directly affect the construction quality of the next process and the realization of the decoration effect.

[0003] The traditional plastering method generally uses a small plastering knife to manually hold the inner corner of the wall formed during the plastering construction process to make a straight straight fill. However, since the straight track of the small plastering knife cannot be fixed, the inner corner plastering will cause a small bend, and the straight inner corner decoration effect cannot be achieved. If the inner corner decoration effect is to be straight, it is necessary to rely on exquisite plastering technology to control the plastering knife to plaster the inner corner, resulting in low construction efficiency and high technical requirements for the operator.

[0004] Therefore, how to improve the plastering efficiency while ensuring the plastering effect of the inner corners of the wall has become a technical problem that needs to be solved urgently by technical personnel in this field. Utility Model Content

DETAILED DESCRIPTION

[0036] The core of the utility model is to provide a plastering device to improve the plastering efficiency while ensuring the plastering effect of the inner corner of the wall.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] like Figure 1 As shown, an embodiment of the utility model discloses a plastering device, including a frame 100 and a plastering assembly 200.

[0039] It should be noted that plastering construction is an indispensable process in building decoration projects. Plastering the corners of the wall is an important task in plastering construction, which involves the beauty of the wall and the stability of the structure. Wall corners are generally divided into wall inner corners and wall outer corners. Wall inner corners usually refer to the concave parts of the wall, that is, the concave corners in the building, such as the concave angle between two walls or the angle between the ceiling and the wall of the room, while wall outer corners refer to the convex parts of the wall, that is, the protruding corners in the building, such as the angle formed by the window and the wall or the protruding angle formed by the two walls at the turning position of the aisle.

[0040] Among them, in the process of plastering the inner corner of the wall, the straightness and squareness of the inner corner of the plastering directly affect the construction quality of the next process and the realization of the decoration effect. The traditional plastering method generally uses a small plastering knife to manually hold the inner corner of the wall formed during the plastering construction process to make a straight straight fill. However, since the straight trajectory of the small plastering knife cannot be fixed, the plastering of the inner corner will cause a small bend, and the decoration effect of the inner corner cannot be achieved. If you want to achieve the decoration effect of the inner corner straight, you need to rely on exquisite plastering technology to control the plastering knife to plaster the inner corner, which leads to low construction efficiency and high technical requirements for the operator.

[0041] The plastering device disclosed in the embodiment of the utility model positions the plastering device through the first positioning member 101 and the second positioning member 102 of the frame 100, and drives the scraper 201 to plaster the corner of the wall through the sliding mechanism 202 arranged on the guide rod 103. Since the first positioning member 101, the second positioning member 102 and the scraper 201 are coaxially arranged, the first positioning member 101, the second positioning member 102 and the scraper 201 are located on the same straight line, thereby ensuring the straight trajectory of the scraper 201. Independent of the operator's plastering technology, the decorative effect of the straight internal corner can be achieved without repeatedly finding the straight line. While ensuring the plastering effect of the internal corner of the wall, the plastering efficiency is improved.

[0042] The plastering device disclosed in the embodiment of the utility model will be specifically explained and illustrated below for the plastering construction of the inner corner of the wall. It should be noted that, unless otherwise specified, the wall corner refers to the inner corner of the wall.

[0043] like Figure 1 and Figure 2As shown, the frame 100 includes a first positioning member 101 and a second positioning member 102, and a guide rod 103 is arranged between the first positioning member 101 and the second positioning member 102. The plastering device is positioned at the corner of the wall by the first positioning member 101 and the second positioning member 102 of the frame 100, and the first positioning member 101 and the second positioning member 102 are respectively attached to the walls on both sides of the corner, so that according to the principle that two points determine a straight line in geometry, it is ensured that the guide rod 103 arranged between the first positioning member 101 and the second positioning member 102 is parallel to the walls on both sides of the corner. At the same time, the plastering assembly 200 includes a plastering scraper 201 and a sliding mechanism 202 connected to the scraper 201. The sliding mechanism 202 can be slidably arranged on the guide rod 103, so that when the sliding mechanism 202 slides along the guide rod 103, the sliding mechanism 202 can drive the scraper 201 connected to the sliding mechanism 202 to plaster the corner of the wall. Since the guide rod 103 is parallel to the walls on both sides of the corner, the scraper 201 moves along a straight track driven by the sliding mechanism 202, thereby avoiding the slight bend of the plastering at the inner corner.

[0044] In order to avoid the defects of local protrusion or depression in the corner of the wall, before plastering the corner of the wall, the scraper 201 needs to be adjusted to be coaxial with the first positioning member 101 and the second positioning member 102, that is, the scraper 201, the first positioning member 101 and the second positioning member 102 are in a collinear position. When plastering the corner of the wall, first position the first positioning member 101 and the second positioning member 102 to the corner of the wall, and ensure that the first positioning member 101 and the second positioning member 102 are respectively in close contact with the wall on both sides of the corner, and then the operator moves the sliding mechanism 202, at which time the scraper 201 moves along a straight track driven by the sliding mechanism 202, so as to achieve a straight decorative effect of the inner corner. When the scraper 201 moves along a straight line, if there is a local raised defect at the corner of the wall, the scraper 201 can be used to wipe off the excess plaster at the raised position of the corner of the wall; if there is a local depressed defect at the corner of the wall, the scraper 201 can be used to fill the depressed position of the corner of the wall with excess plaster, thereby ensuring the flatness of the plastering at the corner of the wall.

[0045] Furthermore, if Figure 1 and Figure 3As shown, in a specific embodiment, the first positioning member 101 includes two first positioning plates 1011 arranged at a first preset angle, and the first preset angle is equal to the opening angle of the corner of the wall, so that the two first positioning plates 1011 are respectively fitted with the walls on both sides of the corner. Among them, the first positioning member 101 can adopt an integrated structure, that is, two first positioning plates 1011 with the first preset angle are formed from a whole steel plate by cutting or other machining methods. Of course, the first positioning member 101 can also adopt a split structure, that is, two steel plates are respectively cut to form connecting sections by cutting or other machining methods to form two first positioning plates 1011, and the connecting sections of the two first positioning plates 1011 are aligned and fixed by welding to form the first positioning member 101. When the first positioning member 101 is positioned at the corner of the wall, since the first preset angle between the two first positioning plates 1011 is equal to the opening angle of the corner of the wall, the outer side surfaces of the two first positioning plates 1011 are respectively fitted with the walls on both sides of the corner.

[0046] At the same time, if Figure 1 and Figure 4 As shown, the second positioning member 102 includes two second positioning plates 1021 arranged at a second preset angle, and the second preset angle is equal to the opening angle of the corner of the wall, so that the two second positioning plates 1021 are respectively fitted with the walls on both sides of the corner. Among them, the second positioning member 102 can adopt an integrated structure, that is, two second positioning plates 1021 with a second preset angle are formed from a whole steel plate by cutting or other machining methods. Of course, the second positioning member 102 can also adopt a split structure, that is, two steel plates are respectively cut to form a connecting section to form two second positioning plates 1021 by cutting or other machining methods, and the connecting sections of the two second positioning plates 1021 are aligned and fixed by welding to form the second positioning member 102. When the second positioning member 102 is positioned at the corner of the wall, since the second preset angle between the two second positioning plates 1021 is equal to the opening angle of the corner of the wall, the outer side surfaces of the two second positioning plates 10211 are respectively fitted with the walls on both sides of the corner.

[0047] Since the first positioning member 101 and the second positioning member 102 are coaxial and parallel, at the same time, the first positioning plate 1011 of the first positioning member 101 and the second positioning plate 1021 of the second positioning member 102 are perpendicular to the walls on both sides of the corner, so as to ensure that the connecting line between the tips formed by the two first positioning plates 1011 and the tips formed by the two second positioning plates 1021 is parallel to the walls on both sides of the corner. In addition, the two ends of the guide rod 103 are respectively connected to the first positioning plate 1011 and the second positioning plate 1021, so that the guide rod 103 is parallel to the walls on both sides of the corner, so as to ensure that the scraper 201 moves along a straight track under the drive of the sliding mechanism 202, so as to achieve a straight decorative effect of the inner corner. In this embodiment, the two ends of the guide rod 103 are respectively connected to the first positioning plate 1011 and the second positioning plate 1021 by welding to ensure the stability of the frame 100. Of course, the two ends of the guide rod 103 can also be connected to the first positioning plate 1011 and the second positioning plate 1021 in a detachable manner. Specifically, through holes are respectively provided on the first positioning plate 1011 and the second positioning plate 1021, and threaded portions are respectively provided on both ends of the guide rod 103. The threaded portions at both ends of the guide rod 103 are respectively passed through the through holes provided on the first positioning plate 1011 and the second positioning plate 1021 and then fastened with nuts. When the opening angle of the corner of the wall changes, the first positioning member 101 and the second positioning member 102 can be replaced to achieve the positioning of the changed corner of the wall by the frame 100, thereby improving the adaptability and turnover of the plastering device.

[0048] It should be noted that the opening angle of the wall corner can be a right angle or an obtuse angle, that is, the opening angle of the wall corner is between 90° and 180°, and the first preset angle and the second preset angle must be equal to the opening angle of the wall corner, so that the outer side surface of the first positioning plate 1011 of the first positioning member 101 and the outer side surface of the second positioning plate 10211 of the second positioning member 102 are respectively attached to the walls on both sides of the corner, thereby realizing the positioning of the plastering device by the first positioning member 101 and the second positioning member 102.

[0049] Furthermore, if Figure 1 and Figure 2As shown, the first positioning member 101 is located above the second positioning member 102, and a connecting rod is connected between the two first positioning plates 1011 by welding to form a gripping portion 1012 between the two first positioning plates 1011. At the same time, a connecting member 1022 is provided between the two second positioning plates 1021, and a top rod 1023 is provided on the connecting member 1022 for facilitating the frame 100 to be pressed against the corner of the wall. Specifically, the connecting member 1022 can be made of a steel plate, and the two ends of the steel plate are respectively fixedly connected to the two second positioning plates 1021 by welding, and a threaded sleeve is welded below the steel plate. The top rod 1023 is threadedly matched with the threaded sleeve to achieve the connection and fixation between the top rod 1023 and the steel plate. Of course, the top rod 1023 can also be fixed directly to the bottom of the steel plate by welding. In order to facilitate the operator to press the frame 100 against the corner of the wall through the top rod 1023, as shown in FIG. Figure 8 As shown, a pad 1024 for applying a tightening force is provided at the end of the top rod 1023, and an arc-shaped fitting surface 1025 is provided on the pad 1024. When the first positioning member 101 and the second positioning member 102 of the frame 100 are positioned at the corner of the wall, the operator can press the frame 100 against the corner of the wall by pressing the body against the arc-shaped fitting surface 1025 on the pad 1024 of the top rod 1023, and at the same time, the operator holds the gripping portion 1012 of the first positioning member 101 and simultaneously applies a thrust to the inner side of the corner of the wall. At this time, the operator slides the sliding mechanism 202 along the guide rod 103, so that the sliding mechanism 202 drives the scraper 201 to plaster the corner of the wall, thereby ensuring the straight trajectory of the scraper, and achieving a straight decorative effect of the inner corner without relying on the operator's plastering skills, without repeatedly finding a straight line, while ensuring the plastering effect of the inner corner of the wall, the plastering efficiency is improved.

[0050] Furthermore, if Figure 1 As shown, in a specific embodiment, the number of guide rods 103 is two. Among them, the two guide rods 103 are arranged in parallel between the first positioning member 101 and the second positioning member 102, so as to improve the operator's controllability over the moving trajectory of the scraper 201 while ensuring the sliding stability of the sliding mechanism 202, so that the operator can more easily control the scraper 201 to move along a straight trajectory, thereby ensuring the decorative effect of a straight internal corner. In addition, the ends of the two guide rods 103 are respectively connected to the two first positioning plates 1011 of the first positioning member 101 and the two second positioning plates 1021 of the second positioning member 102. The specific connection method between the two ends of the guide rod 103 and the first positioning plate 1011 and the second positioning plate 1021 has been explained and illustrated in the above embodiments, and will not be repeated herein. Figure 5 and Figure 6As shown, the sliding mechanism 202 includes guide rail collars 2021 respectively disposed on the two guide rods 103 and slidingly matched with the guide rods 103, a connecting plate 2022 connecting the guide rail collars 2021 is disposed between the two guide rail collars 2021 to ensure that the two guide rail collars 2021 move synchronously along the two guide rods 103, and the scraper 201 is movably disposed on the connecting plate 2022. Specifically, the two ends of the connecting plate 202 are respectively fixed to the two guide rail collars 2021 by welding to connect the two guide rail collars 2021 as a whole, thereby realizing the synchronous movement of the two guide rail collars 2021 along the two guide rods 103. At the same time, a gripper 2023 is provided on the connecting plate 2022 for facilitating the manipulation of the sliding mechanism 202 to slide along the guide rod 103. When plastering the corner of the wall, the operator can hold the gripper 2023 and pull the guide rail rings 2021 at both ends of the connecting plate 202 along the guide rod 103 in the plastering direction. At the same time, the connecting plate 202 drives the scraper 201 to plaster the corner of the wall. There is no need to repeatedly find a straight line, thereby improving the plastering efficiency.

[0051] Furthermore, if Figure 7As shown, in a specific embodiment, the scraper 201 includes two scrapers 2011 arranged at a third preset angle, and the third preset angle is not greater than the opening angle of the corner of the wall, so that the scraper 201 can extend into the corner of the wall for plastering. The scraper 201 can be an integrated structure, that is, two scrapers 2011 with the third preset angle are formed from a whole steel plate by cutting or other machining methods. Of course, the scraper 201 can also be a split structure, that is, two steel plates are respectively cut to form connecting sections by cutting or other machining methods to form two scrapers 2011, and the connecting sections of the two scrapers 2011 are aligned and fixed by welding to form the scraper 201. When the third preset angle is equal to the opening angle of the corner of the wall, the outer side surfaces of the two scrapers 2011 are respectively in contact with the walls on both sides of the corner, thereby ensuring that the scraper 201 moves along a straight line parallel to the wall. Furthermore, a sharp angle 2012 is formed at the connection position of the two scrapers 2011, and the sharp angle 2012 is pressed against the corner of the wall, so that the scraper 201 can plaster the corner of the wall driven by the sliding mechanism 202. When the third preset angle is smaller than the opening angle of the corner of the wall, the sharp angle 2012 formed by the two scrapers 2011 is collinear with the tips formed by the two first positioning plates 1011 and the tips formed by the two second positioning plates 1021, respectively, so as to ensure that the scraper 201 moves along a straight line parallel to the wall. At this time, the sharp angle 2012 of the scraper 201 is pressed against the corner of the wall, so that the scraper 201 can plaster the corner of the wall driven by the sliding mechanism 202. Specifically, a mounting screw 2013 is provided at the connection position of the two scrapers 2011, and a mounting through hole 2024 cooperating with the mounting screw 2013 is provided on the connecting plate 2022. When the mounting screw 2013 of the scraper 201 is inserted into the preset position of the mounting through hole 2024, the mounting screw 2013 and the mounting through hole 2024 are fixed by the fastener 2014. The preset position is a position where the sharp corners 2012 formed by the two scrapers 2011 are collinear with the tips formed by the two first positioning plates 1011 and the tips formed by the two second positioning plates 1021, respectively, so as to avoid the defects of local protrusions or depressions at the corners of the wall and ensure the flatness of the plastering at the corners of the wall. In this embodiment, the mounting screw 2013 is fixed to the connection position of the two scrapers 2011 and to the side opposite to the sharp corner 2012 by welding, such as Figure 7 When the installation screw 2013 of the scraper 201 is inserted into the installation through hole 2024 to a preset position, the installation screw 2013 of the scraper 201 is fixed to the connecting plate 2022 by a nut, thereby realizing the connection between the scraper 201 and the sliding mechanism 202. At the same time, when the wall angle changes or the scraper 201 is damaged, the scraper 201 can be easily replaced without disassembling the entire plastering device, thereby reducing the use cost of the plastering device and further reducing the plastering construction cost.

[0052] Furthermore, if Figure 5 and Figure 7 As shown, in order to prevent the scraper 201 from deflecting or rotating during the process of plastering the corner of the wall or installing the scraper 201, a limiting guide rod 2015 is provided on the scraper plate 2011 of the scraper 201, and a limiting hole 2025 matching the limiting guide rod 2015 is provided on the connecting plate 2022. In this embodiment, there are two limiting guide rods 2015, and the two limiting guide rods 2015 are respectively welded to the two scrapers 2011, and limiting holes 2025 corresponding to the two limiting guide rods 2015 are respectively provided on both sides of the installation through hole 2024 of the connecting plate 2022. When installing the scraper 201, the two limiting guide rods 2015 are respectively inserted into the corresponding limiting holes 2025 on the connecting plate 2022, and the mounting screw rod 2013 is simultaneously inserted through the mounting through hole 2024 on the connecting plate 2022, and after the scraper 201 is adjusted to a preset position, it is fixed by the fastener 2014. The lateral constraint of the limiting guide rod 2015 by the inner wall of the limiting hole 2025 prevents the scraper 201 from deflecting or rotating, thereby improving the installation efficiency of the plastering device and ensuring the stability and plastering effect of the plastering device during the plastering process of the wall corner.

[0053] In a specific embodiment, when the opening angle of the wall corner is a right angle, the first preset angle and the second preset angle are both 90°. Before using the plastering device, place the plastering device on its side on a flat and solid surface, use a ruler longer than the plastering device to press against the 90° tips of the first positioning member 101 and the second positioning member 102, and then adjust the mounting screw 2013 of the scraper 201 so that the sharp corner 2012 of the scraper 201 is in a straight line with the 90° tips of the first positioning member 101 and the second positioning member 102, respectively, and fix them with fasteners 2014, thereby completing the adjustment step. When the wall on both sides of the corner is finished with flat plastering, and the plastering strength reaches the initial setting and begins to generate strength, the operator holds the gripping part 1012 of the first positioning member 101, and uses the waist to support the top rod 1023 of the second positioning member 102, and puts the plastering device at the corner of the wall and presses it tightly. The operator pushes and pulls the gripper 2023 of the sliding mechanism 202 by hand, so that the sliding mechanism 202 drives the scraper 201 to scrape at the corner of the wall, scraping out the excess plaster until the corner of the wall is square and straight. It should be noted that plastering needs to be carried out in sections from top to bottom in the corner of the wall.

[0054] When the opening angle of the wall corner is an obtuse angle, the first preset angle and the second preset angle are both obtuse angles equal to the opening angle of the wall corner. When the walls on both sides of the corner are finished with flat plastering, and the plastering strength reaches the initial setting and begins to produce strength, the operator holds the gripping portion 1012 of the first positioning member 101, and uses the waist to support the top rod 1023 of the second positioning member 102, and puts the plastering device at the corner of the wall and presses it tightly. The operator pushes and pulls the gripper 2023 of the sliding mechanism 202 by hand, so that the sliding mechanism 202 drives the scraper 201 to scrape at the corner of the wall, and scrapes out the excess plaster until the corner of the wall is square and straight. It should be noted that plastering needs to be carried out in sections from top to bottom in the order of the wall corner.
