Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically a plastering device for building construction. Background Technology

[0002] Building plastering refers to the process of applying mortar or mixed materials to the base surface of building walls, ceilings, etc. Its core purpose is to achieve a smooth base, protect the structure, and improve aesthetics and functionality. This construction is completed in layers: the base coat mainly fills holes in the base and enhances adhesion; the middle coat further levels the surface and corrects unevenness; the top coat focuses on decorative effects, improving smoothness and texture. Plastering materials typically include cement, lime, and gypsum, with the proportions selected according to project requirements. This process is widely used in residential and public buildings, not only concealing structural defects but also providing an ideal base for subsequent decorative works (such as painting and tile laying), making it an indispensable foundational step in building decoration.

[0003] Existing plastering trowels generally have limitations in design, with most featuring a straight blade. While this traditional design is efficient for plastering flat walls, it struggles to adapt to complex and varied architectural forms. Particularly when dealing with curved walls, the straight blade cannot closely conform to the curved contours, resulting in uneven application of plaster, hollow areas, or cracks. This not only affects construction efficiency but also compromises the aesthetics and structural stability of the wall. This design limitation forces construction workers to frequently change tools or resort to manual repairs when working on curved walls, arched doors and windows, increasing both the difficulty and cost of the operation. Summary of the Invention

[0004] The purpose of this utility model is to provide a plastering device for building construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastering device for building construction, comprising a handle and a plastering knife, wherein the plastering knife is fixed to the front end of the handle and the plastering knife has a three-sided protruding structure design.

[0006] Preferably, the grip includes a rotating handle, a first fixed rod, a second fixed rod, and a connecting member. A connecting rod is fixedly connected between the first fixed rod and the second fixed rod. The rotating handle is rotatably connected to the outer wall of the connecting rod. The top end of the connecting member is fixedly connected to the bottom end of the second fixed rod.

[0007] Preferably, the plastering trowel includes a straight blade surface, a raised blade surface, and a rounded blade surface. The raised blade surface has two sets of symmetrically fixed on both sides of the top of the raised blade surface, and the rounded blade surface is fixed to the front end of the straight blade surface.

[0008] Preferably, the raised cutting surface is a slanted design with an inner edge protrusion, the rounded cutting surface is a rounded design with a protruding top, and the straight cutting surface is a rounded triangular design.

[0020] Please see Figures 1 to 2 This utility model provides a technical solution: a plastering device for building construction, including a handle 1 and a plastering knife 2. The plastering knife 2 is fixed at the front end of the handle 1 and has a three-sided protruding structure design.

[0021] This plastering trowel 2 boasts an innovative and practical design, employing a multi-faceted approach. Its different blade surfaces adapt to various plastering scenarios, whether flat, sloping, or walls with unusual angles. A single plastering trowel 2 can easily complete the plastering process, significantly improving work efficiency. The attached handle 1 is also ingeniously designed, featuring a rotatable design in the middle. This design allows operators to easily switch angles without frequently adjusting their posture; a simple turn of the handle 1 makes the plastering process easier and more efficient.

[0022] The grip 1 includes a rotating handle 11, a first fixed rod 12, a second fixed rod 13 and a connector 14. A connecting rod is fixedly connected between the first fixed rod 12 and the second fixed rod 13. The rotating handle 11 is rotatably connected to the outer wall of the connecting rod.
