  Next, the best mode for carrying out the present invention will be described with reference to examples.

As shown in FIG. 1, the vibration compaction device 1 according to the present embodiment can be broadly divided into a plate-like rolling plate 3 installed on the lower side of the gantry member 2 so as to be capable of oscillating, and the gantry member 2. A power source means 4 such as an engine installed on the upper side of the motor, a vibrator means 5 for generating vibration by the power of the power source means 4 and applying the vibration to the compaction plate 3, and the gantry member 2 And an operation handle 6 for manual operation having a gate shape as a whole, which is erected substantially obliquely at the rear portion (right side in FIG. 1).
The gantry member 2 has a box-shaped frame body structure, and each of the rolling plate 3, the power source means 4, and the vibrator means 5 is installed by existing means. The exciter means 5 includes a pulley provided on each shaft of an output shaft (not shown) of an engine or the like as the power source means 4 and an input shaft (not shown) of the exciter means 5 and the pulley. The reference numeral 8 denotes a fuel tank in the engine or the like as the power source means 4.

  The rolling plate 3 is doubled from an upper plate member 9a located on the side of the vibrator means 5 and a lower plate member 9b located on the side to be compacted (also referred to as paving material in this specification) W. It is formed in a substantially flat plate shape having a predetermined thickness and extending outside the entire lower surface of the gantry member 2, and the front side (left front side in the figure) and the rear side of the gantry member 2 The end portions on the side (right rear side in the figure) are bent to a desired length so as to be directed obliquely upward. The upper plate member 9a and the lower plate member 9b are both made of a metal plate, but the upper plate member 9a requires an action to effectively propagate vibration from the vibrator means 5, Since the lower plate member 9b needs to have a function of firmly compacting the high-temperature pavement material W, the material of the metal plate is preferably excellent in economy, rigidity, durability, heat resistance and the like, and is preferably made of iron.

  In the rolling plate 3, a heat insulating member 10 facing the lower plate member 9b and a solid sound propagation suppressing member 11 facing the upper plate member 9a are layered between the upper plate member 9a and the lower plate member 9b. The rolling plate 3 as a whole is configured to have a quadruple structure.

The heat insulating member 10 is preferably formed from a material having durability against load and heat and having a high heat insulating effect even if it is a relatively thin plate, particularly carbon fiber, glass wool or the like synthetic fiber having high heat insulating properties. A plate material formed by molding or a plate material formed by wood is preferable. In this case, it is preferable to use a laminated material, particularly a compressed laminated material that has been subjected to a compression treatment, in terms of load durability, heat resistance, and heat insulation, for the plate material formed of wood.
Further, the solid sound propagation suppressing member 11 can suppress the propagation of noise (solid sound) generated (generated) when the lower plate member 9b of the rolling plate 3 strikes the pavement material W during compaction. The upper plate member 9a and the lower plate member 9b are made of a material having a natural frequency different from that of the metal material of the upper plate member 9a and the lower plate member 9b, easily processed into a plate shape, and the vibrator means 5 Therefore, it is desirable to form from a synthetic resin, wood, synthetic fiber molding material, etc., especially hard foam urethane elastomer etc. It is preferable to form it from vibration-proof rubber.
Further, as described above, since the heat insulating member 10 is a material having a natural frequency different from that of a metal material, the heat insulating member 10 also exhibits the function as the solid sound propagation suppressing member 11 described above. In other words, the heat insulation member 10 and the solid sound propagation suppressing member 11 are made of materials having clearly different natural frequencies so that the noise propagation is further suppressed. For example, the solid sound propagation suppressing member 11 is hard. A combination structure such as forming the heat insulating member 10 made of vibration-proof rubber and protecting the heat insulating member 10 from heat from the above-described wood (compressed compressed laminated material) is preferable.

  If the thickness of the heat insulating member 10 and the solid sound propagation suppressing member 11 is too thin, the soundproofing and heat resistance will be inferior. If it is too thick, workability such as compaction will be inferior. A range of ~ 10 mm is preferred.

  The four members of the upper plate member 9a, the heat insulating member 10, the solid sound propagation suppressing member 11, and the lower plate member 9b are not easily separated by heat or vibration, for example, bonding with an adhesive, baking, bolts, nuts, It is integrated by fixing (adhering) means such as a mounting bracket such as a screw or a pin, and in particular, means for fastening and fixing a desired portion with a bolt or nut in a state of being bonded by an adhesive or baking is preferable. The upper plate member 9a can be detachably fastened to the upper plate member 9b, the lower plate member 9b, the heat insulating member 10, and the solid sound propagation suppressing member 11 by means of mounting brackets such as bolts. The three members of the plate member 9b, the heat insulating member 10, and the solid sound propagation suppressing member 11 can be integrated in advance.

  In the present embodiment configured as described above, the compaction plate 3 is placed between the upper plate member 9a and the lower plate member 9b with the solid sound propagation suppressing member 11 in the upper part and the heat insulating member 10 in the lower part. By using a composite (multi-layer) structure interposed in layers, the vibration from the vibrator means 5 is transmitted to the pavement material W by the rolling plate 3 and the compaction of the pavement material W by the rolling plate 3 is efficient. It can be done well and can maintain (maintain) good compaction.

  In the rolling plate 3, the solid sound propagation suppressing member 11 is interposed in the upper part, so that noise generated by hitting the rolling surface of the pavement material W by the rolling plate 3 during the rolling (consolidation) operation. Propagation into the air can be suppressed, and noise during this operation, particularly high-frequency noise and sound pressure of the entire noise can be suppressed as much as possible.

  Further, when the hot pavement material W is pressed (consolidated), the heat conduction of the high temperature pavement material W to the solid sound propagation suppression member 11 is provided by interposing the heat insulating member 10 below the rolling plate 3. Therefore, damage to the solid sound propagation suppressing member 11 due to the heat can be prevented in advance, stable noise suppression can be maintained, and the noise reduction effect can be enhanced as much as possible.

  As a result, in the rolling plate 3 of the present embodiment, effective vibration transmission for compaction can be achieved, and the noise suppression function (prevention function) can be maintained for a long period of time. The durability and life of the resin can be greatly improved.
