Problems solved by technology

At present, the bottom plates of the trowels are all made of metal plates. When the condition of the building base is poor, it is usually necessary to repeatedly smear the colloidal building materials several times to obtain a relatively smooth smeared surface; during this process, in order to check whether the smeared surface is To be smooth, you need to lift the trowel and observe directly with the naked eye. In this way, it is not only difficult to obtain an accurate flat surface, but also more laborious and less efficient

Embodiment 1

[0014] exist figure 1 , figure 2 In the shown embodiment one, the construction trowel includes a knife body and a handle 2; the knife body includes a bottom plate 11, and a convex lens 12 arranged above the bottom plate; the lower surface of the convex lens 12 is a convex surface, The upper surface is a plane parallel to the base plate 11, and the axis of the convex lens 12 is perpendicular to the base plate 11; the base plate 11 and the convex lens 12 are connected by a rigid knife handle 3 connecting rod that runs through the convex lens 12 along the axis of the convex lens; The knife handle connecting rod 3 bends backward on the convex lens 12 and connects the knife handle 2; the bottom plate 11 is also provided with a ring wall 13 surrounding the outer edge of the convex lens 12 to prevent the bottom plate 11 from The colloidal building material on the edge enters the area where the base plate 11 and the convex lens 12 are facing; there is a gap of 0.5-1 mm between the r...

Embodiment 2

[0019] for image 3 The second embodiment shown is different from the first embodiment in that: a ring-shaped light tube 4 is provided directly above the convex lens 12, and the ring-shaped light tube 4 is powered by the battery module 5 in the knife handle 2 ; so as to provide light to the wedge-shaped air layer 100 between the convex lens 12 and the bottom plate 11, so that the annular interference fringes are clearer and more obvious.

Abstract

The invention provides a building construction plastering trowel which comprises a trowel body and a trowel handle. The trowel body comprises a bottom plate and a convex lens arranged above the bottom plate. The lower surface of the convex lens is a convex face, the upper surface of the convex lens is parallel to the plane of the bottom plate, and the axis of the convex lens is orthogonal to the bottom plate. The bottom plate and the convex lens are connected through a rigid trowel handle connecting rod penetrating the convex lens along the axis of the convex lens. The trowel handle connecting rod is bent backwards above the convex lens and is connected with the trowel handle. A circle of ring wall around the outer edge of the convex lens is further arranged on the bottom plate. A clearance ranging from 0.5 mm to 1 mm is arranged between the ring wall and the outer edge of the convex lens. According to the building construction plastering trowel, in the continuous plastering process, a level plastering face can be easily and accurately obtained without lifting the trowel.

Description

technical field [0001] The invention relates to the field of building construction tools, in particular to a trowel. Background technique [0002] In the construction field, a trowel is a commonly used construction tool for applying colloidal building materials on a plane, such as concrete, lime mud, paint, etc.; and usually requires the colloidal building materials to be applied to a flat surface. At present, the bottom plates of the trowels are all made of metal plates. When the condition of the building base surface is poor, it is usually necessary to repeatedly smear the colloidal building materials several times to obtain a relatively smooth smeared surface; For smoothing, it is necessary to lift the trowel and observe directly with the naked eye. In this way, it is not only difficult to obtain an accurate flat surface, but also more laborious and less efficient. Contents of the invention [0003] In view of the above problems, the object of the present invention is ...
