Wheels 10 which are engaged with rails 9 attached to the side frame 3a of the vehicle are mounted, and these wheels 10 are rotated by transmitting power from a prime mover 11 to an axle 8 by a transmission member 12, and the bogie is changed by changing the direction of rotation. 1 is self-propelled forward or backward on the formwork 3.

A support shaft 14 supported by a bearing 13 is provided in front of the bogie 1 in the traveling direction. A pair of swing arms 15 projecting forward of the bogie 1 are provided on the support shaft 14 so as to be vertically swingable. Supported. The leveling roller 4 is mounted on the shaft 16 at the tip of the swing arm 15. When power is transmitted from the motor 17 to the shaft 16 by the transmission member 18, the leveling roller 4 is rotated. Roller 4 on the peripheral surface of roller 4
The right and left spiral leveling strips 19 are formed starting from the center in the length direction. These leveling strips 19 are engaged with the surface of the concrete product 2 and are rotated to increase the height of the product surface. The leveling roller 4 moves the portion from the middle side to the outside to level the level difference generated on the surface of the product. When an aggregate or the like rides, the swing arm 15 swings upward to allow the leveling roller 4 to escape and pass over an obstacle without any trouble.

[0008] The leveling roller 4 needs to be set with its height set so that the leveling strip 19 provided on the peripheral surface thereof is engaged with the surface of the concrete product 2. Therefore, the bearing 13

The lower ends of these suspension shafts 26 are connected to mounting pieces 27 attached to the iron plate 5, and an adjustment nut 28 is screwed into a portion of the suspension shaft 26 that projects above the cushioning material 25. When the adjusting nut 28 is operated, the suspension shaft 26 is raised and lowered so that the lower surface of the iron plate 5 can be adjusted so as to contact the surface of the concrete product 2. After the adjustment, the lock nut 29 is tightened onto the adjustment nut 28 so that the iron plate 5 is held at a position where the iron plate 5 is in contact with the surface of the product. When the vibration is applied to the iron plate 5 by the vibration exciter 30, the iron plate 5 vibrates freely, but the vibration is not transmitted to the carriage 1.

When the iron plate 5 is not used,
It is necessary to keep it away from the surface of the concrete product 2. For this reason, as shown in FIGS. 6 and 7, an extension 27 a facing the inside of the bogie 1 is provided above the mounting plate 27 of the iron plate 5,
A window hole 31 is formed at the upper end of the extension 27, and a shaft 33 supported by a bearing 32 provided on the carriage 1 penetrates the window hole 31, and the shaft 33 has an eccentric located in the window hole 31. The cam 34 is fixed, and the operation handle 35 is attached to the outer end. Then, when the shaft 33 is rotated by the operation handle 35 to turn the eccentric cam 34 downward as shown in FIG.
The extension portion 27a and the attachment piece 27 are lowered to lower the iron plate 5, and the lower surface thereof is brought into contact with the surface of the concrete product 2 as shown in FIG. 6, but when the eccentric cam 34 is rotated upward as shown in FIG. The extension 27a and the mounting piece 27 are raised to raise the iron plate 5, and the lower surface thereof is separated from the surface of the concrete product 2 as shown in FIG. The raising and lowering of the mounting plate 27 and its extension 27a is not limited to the eccentric cam 34 described above, and many other mechanisms can be adopted.

As shown in FIGS. 1 and 2, a pair of bearings 36 are attached to the rear portion of the bogie 1. Arms 37 are respectively attached to these bearings 36, and a concrete Numerous streaks 39 that nibble on the surface of product 2
Is attached to the shaft 41 by the turning bracket 40. And the said creased member 6
The arm 3 must be held at a position where the tip of the filament 39 bites into the surface of the concrete product.
An adjusting screw 42 is screwed near the base of 7, and a receiving piece 43 attached to the carriage 1 is provided below the adjusting screw 42.
When the adjusting screw 42 is pulled out downward, the arm 37 is raised upward to move the creased member 6 away from the surface of the concrete product 2. However, when the adjusting screw 42 is returned upward, the arm 37 is lowered and the creased member 6 is brought close to the surface so that the tip of the wire 39 is appropriately bitten into the surface of the concrete product 2. Is stopped, and the crease member 6 is fixed. In addition, since the scoring member 6 is attached to the shaft 41 by the rotating metal fitting 40, the rotating metal fitting 40 may be rotated about the shaft 41 as shown by a chain line in FIG. it can.

When the creased member 6 is not used, it is preferable that the arm 37 is held above the carriage 1, and in this case, the arm 37 is rotated to a position above the carriage 1 as shown by a chain line in FIG. The head of the adjusting screw 42 screwed to the arm 37 is
Arm 37 stops when it is placed in contact with the upper end of
And stably holds the creased member 6 in the non-use position.

In the concrete product surface finishing apparatus shown in the above embodiment, when the concrete product 2 is formed by the mold frame 3, the wheel 10 is engaged with the rail 9 attached to the side frame 3a to form the bogie 1 into the mold. Place on frame 3. Then, the leveling roller 4, the iron plate 5, and the creased member 6 are positioned so as to act on the concrete surface, the leveling roller is rotated by the prime mover 17, and the iron plate 5 is vibrated by the vibrator 30. When the wheels 10 are rotated by the prime mover 11, the bogie 1 is
The vehicle runs on the concrete product 2 based on a. Then, the leveling roller 4 in the front in the traveling direction rolls on the surface of the concrete product 2 first, and the surface concrete, which is normally struck at a middle and high level, is moved from the inside to the outside by the leveling 19 provided on the peripheral surface. Level the surface so that there is no height difference. Next, the surface of the concrete product 2 is stroked while the iron plate 5 vibrates slightly, and the surface of the concrete product 2 is rubbed while floating the moisture of the concrete on the surface to finish it into a flat and dense surface. Next, the creasing member 6 scratches the surface of the concrete product 2 with a number of filaments 39 to form a streak on the surface, so that the concrete product 2 is completed in one continuous step of surface finishing and creasing by this operation. I do.

The surface finish condition of the concrete product 2 differs depending on the product. When only rough leveling for leveling the surface is sufficient, when finishing to a flat and dense state is performed, or after finishing, In the case of creasing, there may be no creasing, etc., and even when performing roughing and finishing and creasing, it is not performed in one continuous step as described above,
When the pre-process is completed, there may be a case where the time to reach a surface state suitable for the next process is set before moving to the next process. Therefore, in such a case, if the leveling roller 4 is placed at the use position and the iron plate 5 and the creased member 6 are placed at the non-use position and the carriage 1 is run, the surface of the concrete product 2 is roughened. I can only do it. Also, if the trolley plate 5 is placed at the use position and the carriage 1 with the leveling roller 4 and the creased member 6 placed at the non-use position is run, the surface of the concrete product 2 can be finished flat. Furthermore, if the carriage 1 is run with the creasing member 6 placed at the use position and the leveling roller 4 and the iron plate 5 at the non-use position, the surface of the concrete product 2 can be creasing.

Further, a plurality of iron plates 5 are provided on the carriage 1 as shown in FIG.
If the amplitude of 0, 30 is set to be smaller in the rear part than in the front part in the traveling direction, the surface of the concrete product 2 can be stroked while micro-vibrating the iron plates 5, 5 with different amplitudes. Since the operation of troweling the surface while floating the water of the concrete on the surface is repeatedly performed with different amplitudes, it is possible to obtain a finished surface having more excellent surface flatness and denseness than finishing with one iron plate 5. be able to.

[0017]

According to the first aspect of the present invention, a leveling roller, a trowel, and a creasing member are attached to a self-propelled carriage guided by a side frame of a formwork. The surface finishing and creasing of the concrete product can be accurately performed on the basis of the side frame only by operating the bogie by acting on the surface, and no labor is required for the work. According to the second aspect of the present invention, if the trolley is run by simultaneously applying the leveling roller, the iron plate, and the creasing member to the surface of the concrete product, the surface of the concrete product is roughly leveled so that there is no difference in elevation, and then flattened. To finish the process on a secret surface and complete the creasing work on this surface in one process. Advantageous Effects of Claim 3 Because one or two of the leveling roller, the iron plate, and the creasing member can be selectively applied to the surface of the concrete product, the surface can be roughened, finished, and creasing alone. It is possible to select selectively or to select a combination of the two processes of roughening, finishing and creasing, so that the finishing can be efficiently performed according to the finishing degree and finishing accuracy of the concrete product. Effect of Claim 4 When a plurality of iron plates are provided and vibrated under different vibration conditions, an operation of rubbing while floating concrete water on the surface is repeatedly performed under different conditions. Denseness is further improved compared to finishing with a single iron plate.
