Detailed Description
To make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be further described with reference to the accompanying drawings. The following description is of the preferred embodiment of the present invention and is provided to enable a person of ordinary skill in the art to make and use the invention and is not intended to identify key or critical elements of the invention or to delineate the scope of the invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood as a specific case by those skilled in the art.
Referring to fig. 1 and 2, an embodiment of the present invention provides a tool for plastering an external corner chamfer, which is mainly applied to building inverted external corner construction such as a stand step, a stair step, a decorative molding, etc., in the embodiment, the stair step is taken as an example for explanation, and the tool mainly includes a horizontal plate 1, a vertical plate 2 and an outer frame.
As shown in fig. 2, the vertical plate 2 is disposed in a vertical direction of the horizontal plate 1. The horizontal plate 1 and the vertical plate 2 are arranged vertically, but the horizontal plate 1 and the vertical plate 2 are not directly intersected, an intersection line L exists between a plane where the vertical plate 2 is located and a plane where the horizontal plate 1 is located, two adjacent edges of the horizontal plate 1 and the vertical plate 2 are mutually parallel to form an ash scraping plane, the ash scraping plane is an inclined plane, and the ash scraping plane is the shape of a male chamfer plane.
The inclination angle of the ash scraping plane, namely the angle of the inverted external corner, can be flexibly set according to the building design requirement. If the included angle between the ash scraping plane and the horizontal plate 1 and the included angle between the ash scraping plane and the vertical plate 2 are the same, namely the inverted external angle is 45 degrees, at the moment, the distances from two adjacent sides of the horizontal plate 1 and the vertical plate 2 to the intersecting line L are the same. Similarly, the included angle between the ash scraping plane and the horizontal plate 1 and the included angle between the ash scraping plane and the vertical plate 2 are different, that is, the inverted external angle is not 45 degrees, and if the inverted external angle is 30 degrees, 60 degrees or the like, the distances from the two adjacent edges of the horizontal plate 1 and the vertical plate 2 to the intersecting line L are different.
Besides the angle of the inverted external corner, the side length of the section of the inverted external corner can be flexibly set according to the requirement of building design. The distances from two adjacent edges of the horizontal plate 1 and the vertical plate 2 to the intersecting line L are respectively adjusted, so that the side length of the inverted external corner can be adjusted. Meanwhile, in order to facilitate plastering operation, the length of the horizontal plate 1 is the same as that of the vertical plate 2, and is set to be about 0.5-1.5 m, namely the length of one-time chamfering of the tool is controlled to be about 0.5-1.5 m.
Because the horizontal plate 1 and the vertical plate 2 both have a certain thickness, the plastering knife 7 may be affected when the chamfering operation is performed, so that the horizontal plate 1 and the vertical plate 2 both select an oblique scraping rule, and the back of the oblique scraping rule is provided with an oblique scraping surface 5. The cross-sectional shape of oblique scraping ruler is right trapezoid, like this the horizontal plate 1 with the adjacent both sides of vertical board 2 all become the conical surface setting, and the plastering trowel 7 of being convenient for is scraped.
The outer frame is respectively connected with the horizontal plate 1 and the vertical plate 2 and used for supporting and positioning the horizontal plate 1 and the vertical plate 2. As shown in fig. 1, the outer frame includes two L-shaped brackets 3, the two brackets 3 are disposed in parallel and opposite to each other and are respectively located outside two ends of the horizontal plate 1 and the vertical plate 2, and two ends of each bracket 3 are respectively connected to the back of the horizontal plate 1 and the back of the vertical plate 2.
In addition, the structural strength of the tool is improved, the outer frame further comprises two cushion strips 4, the two cushion strips 4 are respectively arranged on the outer edge of the back face of the horizontal plate 1 and the outer edge of the back face of the vertical plate 2 along the length direction, and two ends of each support 3 are respectively connected with two ends of the same side of the two cushion strips 4.
This instrument is mainly applied to the construction site construction, for the purpose of being convenient for draw materials, in this embodiment the support 3 with filler strip 4 is the square steel, just support 3, filler strip 4 horizontal plate 1 with all through welded connection between the vertical board 2. It is understood that the materials of the components can also be flexibly selected according to the actual application scenario, and are not limited in the present embodiment.
As shown in fig. 3, when the tool for plastering the external corner chamfer is used for construction, after the stair step 6 is constructed, the vertical plate 2 of the tool is attached to the vertical surface of the stair step 6, the horizontal plate 1 is attached to the plane of the stair step, so that the tool is clamped on the stair step 6, then the plastering knife 7 scrapes the ash along the ash scraping plane, and the chamfer is plastered to close the surface, so that the external corner chamfer can be finished. Further, as shown in fig. 4, for each step of the stair step 6, the same tool can be used for performing external corner chamfering construction so as to ensure the consistency of the external corner chamfering of each step of the stair step 6.
In this document, the terms front, back, upper, lower and the like in the drawings are used for the sake of clarity and convenience only for the components are located in the drawings and the positions of the components relative to each other. It should be understood that they are relative concepts, which may be varied in relation to their use and placement, and that the use of directional terms should not be taken to limit the scope of the claims.
