Description

[Detailed description of the invention] This invention is a paving rug that is used to manually spread relatively high-viscosity paving materials such as resin paint or resin mortar close to the surface to be paved. Regarding.

In recent years, the finishing of floors in gymnasiums, etc. has been carried out by uniformly spreading resin paint on the floor, but the spreading work still requires full plastering. It is used.

With this full-spindle method, workers were forced to spread over a relatively wide area in a half-hearted state, resulting in severe fatigue and poor efficiency.

Furthermore, since resin mortar uses resin instead of cement as a binder, it generally has a high viscosity, and requires greater force to spread, and it is difficult to maintain a constant coating thickness. It required considerable skill to do so.

On the other hand, items that allow you to work while standing include:
There is a drainer used for cleaning toilets, etc., but the rubber plate of this drainer is too soft and weak, so it cannot spread high-viscosity paving materials.

Therefore, the object of this invention is to provide a paving rug that can uniformly spread a relatively high-viscosity paving material in a comfortable posture.

Hereinafter, embodiments of this invention will be described with reference to the accompanying drawings.

As shown in Figure 1, the leveling tool invented by this invention is
The stem 1 is preferably formed to have a length of 1 m or more so that work can be performed in a standing position.

This stem 1 has a handle 2 formed at one end thereof,
Further, a weight plate 3 is attached to the other end in a T-shape.

The weight plate 3 is made of a highly elastic and strong oblong plate member made of spring steel, reinforcing wire-containing comb, hard rubber, or flexible synthetic resin. A plurality of sawtooth cut grooves 4 are provided in a V-shape.

In this case, the weight plate 3 is fixed to the stem 1 at a predetermined angle (preferably around 150 degrees) via a metal holding member 5, as shown in FIG.

To explain in more detail, the holding member 5 includes a first fixture 6 that holds the upper edge of the weight plate 3, and a second fixture 7 that is attached to the stem 1 side.

The fixing fitting 7 is formed by bending a metal plate as shown in FIG. It is also screwed to the center of the upper side of the first fixture 6 with a screw or the like inserted through the screw hole 8 .

As shown in FIG. 4, when this paving material is pulled in the direction of arrow A while being slightly pressed through the stem 1, a certain amount of paving material 10 is released from the serrated grooves 4.
is pushed out and spread on the floor surface 11.

In this case, an indentation line is formed by the convex portion of the cut groove 4, but this indentation line gradually disappears due to the malleability of the paving material 10, resulting in a smooth surface.

Note that by changing the width of the serrated grooves 4, the amount of spreading can be adjusted, and by changing the depth of each groove, the coating thickness can be adjusted.

Further, the shape of the cut groove 4 provided at the lower edge of the weight plate 3 is not particularly limited to that shown in this embodiment, and may be, for example, wave-shaped.

Furthermore, the angle of inclination between the stem 1 and the plane of the weight plate 3 can be made adjustable in consideration of usage and workability.

For example, as shown in FIG. 5, the first fixture 6 and the second fixture 7 are connected by a hinge 12, and an angle adjustment plate 13 is attached to one of them between the two. , and a set screw 14 that cooperates with this angle adjustment plate is provided on the other side.

As is clear from the above description of the embodiments, this invention allows workers to work while standing, reducing worker fatigue.Also, since construction can be carried out while observing the overall performance, paving materials can be used more efficiently. It can be spread evenly.

In addition, the coating width of the weight plate can be made several times longer than that of conventional plastering trowels, which greatly improves work efficiency.

Furthermore, by changing the depth and width of the cut at the lower edge of the weight plate, the amount of spreading and the coating thickness can be adjusted.

On the other hand, since the weight plate is made of an elastic material that does not easily undergo buckling deformation, the applied force can be adjusted appropriately, and therefore uniform spreading can be performed without requiring any skill.
