First, I roughly smashed with a wooden trowel, and then finished with a metal trowel. Although not shown in the drawing, this finishing trowel has a structure in which a regular U-shaped notch is provided on one peripheral edge in the longitudinal direction of the trowel plate. Finishing was done by extruding sand and mortar in the ready-made concrete onto the surface.

題点があった。[Problems to be solved by the invention] However, in rough smashing with a wooden trowel, although gravel in fresh concrete is pushed in, sand and mortar are not pushed out to the surface, so it is easier However, even in the subsequent finishing with the iron trowel, the extrusion of sand and mortar by the U-shaped notch is not effective because only the concrete in the U-shaped notch is raised. There was a problem that finishing with was not easy.

しこてを提供することにある。The present invention has been made in view of such conventional problems, and an object thereof is to push gravel in fresh concrete and to remove sand or mortar in rough crushing of fresh concrete. The purpose is to provide a fresh concrete trowel that is extruded to the surface and facilitates subsequent finish leveling.

FIG. 1 is a side view showing an example of a leveling iron according to the present invention, FIG. In a trowel for ready-mixed concrete, including a grip handle 13 which is laterally provided on the trowel plate 10 via support legs 11 and 12,
The trowel plate 10 is characterized in that a large number of continuous groove portions 14 are provided on at least one side peripheral portion in the longitudinal direction on the bottom surface of the trowel plate 10. The supporting leg may be one, and the structure and grip of the supporting leg are also possible. The structure of the handle is not an essential part of the present invention, and therefore, these include all known ones.

る。To explain further, the iron plate 10 is made of wood or hard resin, and its shape is a well-known shape such as a rectangular plate shape with a sharp tip. In the longitudinal direction of the bottom surface of the trowel plate 10, as shown in FIGS. 1 and 2, on at least one side of the peripheral edge thereof, and at a predetermined equal interval from the rear end to just before the front end. A large number of concave groove portions 14 are provided so as to be continuously arranged in parallel in the lateral direction. In the case of rough blasting of ready-mixed concrete, the groove 14 pushes out sand or mortar in the fresh concrete to the surface, so that a flat iron plate without the groove 14 can be used for leveling or with a metal trowel. It has the function of facilitating the smoothing of the finish, and when applying a top coat on fresh concrete, it forms a rough surface on the concrete surface in order to eliminate the deformation of the base and increase the adhesive strength. It has a function for.

ることができる。The recessed groove portion 14 may be provided on the peripheral portion on either the left or right side in the longitudinal direction, and need not be provided on the left and right sides. As described above, this is because the gravel in the green concrete is pushed in on the flat surface including the peripheral portion on one side, and the sand and the mortar in the green concrete are applied to the surface in the groove portion 14 in the groove portion 14 on the other side. This is because it is easy to extrude and smooth the next smoothing. The cross-sectional shape, width, interval, and other dimensions of the groove portion 14 can be set as appropriate.

Since it is extruded to the surface in the concave groove portion, it becomes easier to smooth and the workability of the next finishing smoothing can be improved. Further, even when applying the overcoating agent, if the rough surface is formed by the concave groove portion, the adhesive force can be increased without being disturbed by the base.
