Description

Tools for plastering work

[0001] The present invention relates to a plastering instrument used for a surface finishing operation in a plastering operation of an interior surface.

Plastering is an operation of finishing the inner wall of a concrete building or a masonry building using bricks with cement mortar (or remital).

In the plastering operation, first, the remital is first applied to the plastered surface with a predetermined thickness, and while the water remains on the remital, the surface is rubbed with a trowel to remove the marks and nourish the surface. Afterwards, wet the primed surface with water, and if there is a place where the primer is applied too thickly, purify it, apply the entire surface with mortar and rub the surface with a trowel or the like.

Next, after the chaebol application is dry and hardened, wet it and perform the chaebol application. Finally, the surface is finished with an iron trowel or other finishing equipment.

When the operator performs the surface finishing, the surface is leveled by the operator's eyes or intuition. Since the leveling of the plastering surface requires a high level of skill, when a worker with low skill level performs the work, there is a problem that the plastering quality is greatly deteriorated and a lot of work time is required.

In addition, when relying only on the skill level of the operator, it is very difficult to keep the thickness of the plastered surface uniform, and there is a inconvenience of measuring the thickness of the plastering surface during plastering work.

Referring to FIGS. 6 and 8 , a cosmetic appliance including the rail 300A shown in FIG. 2 may be installed near a corner of an indoor wall near a bathroom. After the first body 100 is in contact with the indoor ceiling, and the length of the plastering device is reduced and fixed so that the second body 200 is in contact with the indoor floor, the guide surface G is placed on the reference surface L of the plastering surface. Move the decorative tool to position, at this time, the first surface 110 is in contact with the installation wall (S). And the guide surface (G) is arranged to be spaced apart by a first distance from the construction wall (W) by the plaster thickness (t). Here, the first distance corresponds to the plaster thickness (t) as the shortest linear distance between the reference plane (L) of the plastered surface and the construction wall (W).

Thereafter, the position is positioned so that the cosmetic appliance is vertical through the leveling system 500 . When the plastering apparatus is installed to be perpendicular to the indoor ceiling and indoor floor, the guide surface G is disposed parallel to the reference surface L of the plastering surface.

The length D of the rail 300A may be variously changed and set to correspond to the installation environment of the plastering apparatus.

The contact surface 11 of the pusher 10 is brought into contact with the guide surface G, and the surface finishing operation is performed while moving the pusher 10 along the guide surface G from the upper side to the lower side or from the lower side to the upper side.

Referring to FIG. 7 , two plastering instruments including the rail 300A shown in FIG. 2 are respectively disposed on one side and the other side, and each guide surface G of the two plastering apparatuses is a reference surface of the plastering surface. It may be arranged parallel to (L).

Referring to Figures 7 and 9, the rail 300B shown in Figure 4 in the vicinity of the angled corner wall may be installed for the decoration.
