。The area required to construct one surface of these elastic sports floors, such as a tennis court, is approximately 670 mm, and even if this were to be constructed on all four sides, the required area is approximately 2,408 mm, which is relatively small. However, it is too narrow to use large-scale paving machines such as those commonly used for road paving work.
Therefore, in most cases, when constructing a rubber chip layer, the rubber chips are spread by hand, spread out using wooden boards, and then
Because the method used is to level the surface with a plasterer, the thickness of the resulting rubber chip layer tends to be uneven.
Leveling with a plasterer is carried out in a half-hearted position, which causes severe fatigue for the workers and, therefore, poor work efficiency. Furthermore, the surface of the rubber chip layer is usually coated with a viscous steel binder such as urethane resin, so in order to spread it evenly, use a leveling tool such as a mirror to average the appropriate shearing force of the trout. A high degree of proficiency is required, such as having to add
Therefore, finishing accuracy varies depending on the skill level of the workers, and since rubber chips tend to adhere to the surface of the eel, it sometimes takes time to remove them, which poses considerable difficulties in terms of construction efficiency and accuracy. . In view of the above-mentioned current situation, it is an object of the present invention to provide a small and light portable floor rubber chip leveling device suitable for use at construction sites of relatively small-scale elastic floor structures for sports as illustrated above. With the goal.

The leveling thickness is adjusted, and in this example device, the tamper plate 2 adjusts the length of the support birch 2a located at the front in the direction of travel to that of the rear support birch 2a2, as shown in FIG. By setting it shorter, it is attached to the mounting frame main body 1 in such a manner that it slopes upward as it reaches the front green portion. The tamper plate 2 has a pair of vertical frames 5 on its back surface that are spaced apart from each other and fixed in parallel to each other, and the vibrator 4 is mounted on a mounting plate 6 that spans both vertical frames. The rubber chips are vibrated up and down by the vibrator 4, and the rubber chips are compacted and laid to a required thickness t.

具１２を備える。The hopper part 7 is equipped with a wire mesh 9 that is removably hooked at both ends to a U-shaped fitting 8, and the rubber chips accumulated and stored in the hopper part 7 are protected by their own weight and the progress of counterfeiting. Due to the accompanying vibrations, the material falls from the mesh of the wire mesh 9 onto the work surface, and is rolled and leveled by the aforementioned tamper plate 2 located at the rear. Further, the hopper part 7 is located below the wire mesh 9 and has a sliding type closing plate 1 that closes the entrance of the part.
0. In FIG. 1, the closing plate 10 includes a handle 1 that penetrates the front frame portion lc of the mounting frame body 1 and projects forward.
By pulling out 0a forward, the entrance of the hopper section 7 is opened. In this example, the mounting frame body 1

Further, the overlap width with the already leveled surface is determined by the distance 1 of the leveling width adjuster 12. As mentioned above, the leveling width adjustment member 12 is installed directly from the right green of the mounting frame body 1 at a position quite close to the center, so it is formed to a length that ends at the front green of the entrance of the hopper part 7. .

As shown in part, it has a hemispherical sliding body 13a at its tip, extends upward through the oblong through hole 13b of the tamper plate 2, and its upper end is attached to the vertical equipment 3 of the tamper hanging attachment 3.
A height adjustment rod 13 fixed at d is provided. Furthermore, as mentioned above, since the rubber chips will be scattered partially overlapping the leveled surface, the mounting A protrusion prevention plate 14 made of inverted L-shaped steel is provided on the lower surface of the right side frame portion lb of the frame body 1, as shown by the dotted line in FIG. The apparatus of this example has a towing rope mooring ring 15 on the front surface of the front frame part lc of the mounting frame main body 1, and a guide ring 16 mounted on the outer surface of the left side frame part la of the main body 1 so as to be able to be turned upside down. This guide wheel is an all-legged rail 17 with a chevron-shaped cross section.
While placed on top of the mooring ring 15, the mooring ring 15 is towed and moved forward via a rope tied to the mooring ring 15 by a small towing vehicle or a winch. The details of the rubber chip leveling operation using the apparatus of this embodiment having the above-mentioned configuration are as follows.
