[0042] Furthermore, in the description of the technical scheme of the utility model, unless another explicit provision / limitation / restriction, the term "set" "install" "connect" "connect" "set" "lay" "arrange" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected, which can be welding, riveting, bolting, screwing and other commonly used connecting means in the art. Such connection can be mechanical connection, electrical connection or communication connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be connected inside two elements.

[0043] In the related art, when the top of the concrete structure is finished, if the formwork structure height is consistent with the design structure height, the finishing operation is performed according to the formwork surface, and on this basis, if the top of the structure has a chamfer, the overall finishing is performed first, and then the mold is pressed to chamfer. The process is complex, and the smoothness of the chamfer depends on the proficiency of the worker. If the formwork height is higher than the design structure height, the finishing operation is performed by manually inserting the trowel into the formwork top below through artificial pull lines. Such finishing is affected by human factors, and the top is not smooth and beautiful after the formwork is removed, and it is necessary to re-invest human resources for polishing and finishing. In the above two ways, additional processes are required, thereby increasing the operation time and labor cost. Therefore, the technical scheme of the present application is generated, which is described below in combination with Figures 1 to 6 .

[0044] Embodiment 1

[0045] As Figures 1 to 5 indicated, the adjustable concrete finishing trowel of the utility model comprises a bottom die 1 and a carrier 2.

[0046] Utilizing the principle of three points to establish a plane, at least three strip holes 31 are arranged on the periphery of the carrier 2, the length direction of the strip hole 31 is arranged along the thickness direction of the carrier 2, one roller 6 is arranged corresponding to each strip hole 31, the rotating shaft of the roller 6 is detachably connected to the strip hole 31, and the bottom die 1 is connected to the bottom of the carrier 2.

[0047] In an optional embodiment, as Figures 1 to 3 indicated, the carrier 2 adopts a rectangular rigid steel plate structure, at least two ear plates 3 are arranged on each long side of the carrier 2, the ear plate 3 is arranged perpendicular to the carrier 2, the ear plate 3 and the carrier 2 are welded, or the ear plate 3 and the carrier 2 are integrally formed, for example, the ear plate 3 is integrated with the carrier 2 in one plane during manufacturing, and the ear plate 3 is cold-rolled perpendicular to the carrier 2; the strip hole 31 is vertically arranged on each ear plate 3, and the ear plate 3 is preferably arranged at both ends of each long side, the rotating shaft of the roller 6 is perpendicular to the long side direction of the carrier 2, that is, four rollers 6 are arranged on the carrier 2.

[0048] In one alternative implementation, such as Figures 1 to 3 As shown, the bottom mold 1 adopts a rectangular stainless steel structure. The bottom mold 1 and the carrier 2 have the same length and width. The bottom mold 1 is bonded, welded, bolted, or magnetically connected to the carrier 2. The bonding and welding methods are easy to understand. The bolting or magnetic connection method involves setting blind holes on the top surface of the bottom mold 1, and fixing magnets or bolt heads in the blind holes. The carrier 2 is attracted by the magnets, or the bolts pass through the carrier 2 from bottom to top and are tightened by nuts. It should be noted that if the magnetic method is used, the bottom mold 1 and the carrier 2 need to be additionally provided with limiting protrusions and limiting grooves for limiting cooperation to prevent the magnetic attraction from falling off due to shear force between the bottom mold 1 and the carrier 2 when the trowel is used.

[0049] In one alternative implementation, such as Figures 1 to 3 As shown, the roller 6 includes a bearing, which is connected to the strip hole 31 by bolts 4 and fastened by nuts, thereby fixing the roller 6 relative to the ear plate 3.

[0050] In one alternative implementation, such as Figures 1 to 3 As shown, the carrier 2 is provided with a handle 5, which makes it convenient for construction personnel to hold the trowel through the handle 5.

[0051] In some optional embodiments, at least one of the two sides of the bottom mold 1 along its length is provided with a chamfer structure 11, the structure of which matches the chamfer requirements of the concrete structure 8, such as a 45° chamfer or a rounded chamfer, etc.

[0052] When using, such as Figure 4 or Figure 5 As shown, the widths of the bottom mold 1 and the carrier 2 match the width of the concrete structure 8, thus determining the height difference between the height of the concrete structure 8 and the height of the formwork 7.

[0053] Figure 4If the height of the template 7 is consistent with the height of the concrete structure 8, then the bolt 4 is loosened, the position of the bolt 4 in the strip-shaped hole 31 is adjusted, the wheel bottom of the roller 6 is located in the same plane with the bottom surface of the bottom die 1, the bolt 4 is tightened, the roller 6 is placed on the top surface of the template 7, the bottom surface of the bottom die 1 is matched to the top surface of the concrete structure 8, and the carrier 2 is moved along the top surface of the template 7 by the handle 5, so that the top surface of the concrete structure 8 is smoothed by the bottom die 1.

[0054] Figure 5 If the height of the template 7 is higher than the height of the concrete structure 8, compared with the case that the height of the template 7 is consistent with the height of the concrete structure 8, only the wheel bottom of the roller 6 is higher than the bottom surface of the bottom die 1, and the height difference is consistent with the height difference between the template 7 and the concrete structure 8, so that the bottom die 1 can be inserted into the template 7 to smooth the concrete structure 8, and the bottom die 1 does not need to be manually pulled into the template 7 to smooth the concrete structure 8. Figure 4

[0055] The adjustable concrete smoothing trowel has the advantages that the height position of the roller 6 can be adjusted along the length direction of the strip-shaped hole 31, that is, the relative height between the wheel bottom of the roller 6 and the bottom surface of the bottom die 1 can be adjusted, that the roller 6 is suitable for the case that the height of the template 7 is consistent with the height of the concrete structure 8 when the wheel bottom of the roller 6 is located in the same plane with the bottom surface of the bottom die 1, that the roller 6 is suitable for the case that the height of the template 7 is higher than the height of the concrete structure 8 when the wheel bottom of the roller 6 is higher than the bottom surface of the bottom die 1, that the top surface of the concrete structure 8 can be directly formed by the bottom surface of the bottom die 1, including the case that chamfering is needed, so that the operation time and cost are reduced, and that the trowel has the advantages of simple structure, convenient use and good effect.

[0056] Embodiment 2

[0057] As shown in Figure 6 The adjustable concrete smoothing trowel is different from the embodiment 1 in that the bottom die 1 and the carrier 2 are arc-shaped plates and have consistent sizes in the embodiment, so that the top of a ring-shaped or arc-shaped structure can be smoothed.

[0058] ​In an alternative embodiment, at least two of the ear plates 3 are provided on each of the arc-shaped edges of the carrier 2, preferably one at each end of the arc-shaped edges, and the rotation axis of the roller 6 is perpendicular to the tangential direction of the arc-shaped edges of the carrier 2, i.e. the roller 6 can move along the top surface of the arc-shaped template 7, as shown by the arrow in Figure 6

[0059] The above merely provides the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall fall within the protection scope of the present application.​
