In the mechanical forming of concrete structures, fresh concrete with low slump is used, so air is added to improve fluidity (workability).
% to 6%. Then, a vibrator is used to apply vibrations, and the vibration force is propagated to each part of the ready-mixed concrete via coarse aggregate and air. As described above, air plays an important role in the mechanical forming of concrete structures, but if air is present even after finishing the forming, it will reduce the strength of the structure, so it must be degassed. If the air is not properly vented, the internal pressure will cause the concrete structure to swell and deform the mold after forming. This deformation phenomenon is caused by paving stoppers (Fig. 5 A) and retaining walls (Fig. 5 A).
Concrete structures with high and wide walls (referred to as high structural concrete structures ), large concrete structures such as breakwaters (Figure 6 A), foundations and concrete rails for Hakama-za type monorails (Figure 6 B), large U-shaped ditches (Figure 6 C), or concrete pavement (Figure 7 Figure A), the so-called L gutter (road curb)
(Fig. 7 B), apron-type road curb foundations (Fig. 7 C), and concrete pavements integrated with L gutter (Fig. 7 D). Concrete structures). Furthermore, conventionally, when the air in the surface area is deaerated after demolding, the surface of the concrete structure is roughened in the form of pockmarks, and deaeration marks are formed on the surface. Such deformation and deaeration marks not only result in poor aesthetics but also reduce strength. however,
In the past, no effective measures could be taken against such deformation and degassing marks. As a result, a great deal of effort and time was spent on backfilling the deaeration marks or on subsequent post-process work for finishing corrections.

Next, a molding frame for an automatic continuous concrete structure molding machine according to the present invention will be explained based on an embodiment shown in the drawings. Reference numeral 1 denotes a formwork that is attached to the lower part of the automatic continuous molding machine for concrete structures and moves as the machine advances, as indicated by the dotted chain line. The formwork 1 has an inflow section 2 into which fresh concrete is introduced, and an inflow section 2.
It consists of a degassing section 3 that communicates with the finishing section 4 and a finishing section 4. The inflow section 2 consists of a front plate 5 and a side plate 6, and an input port 7 is provided in the ceiling. On both sides of the degassing section 3, along the traveling direction, in this example, several strip plates 8 are arranged parallel to the bottom section 1a.
A to 8e are hung horizontally, and a slit 9 of an appropriate width is formed between each strip plate 8. In this example, the dimensions of each strip plate 8 are approximately 200 mm.
mm to about 300 mm, and the strip plate 8a is about 150 mm to 250 mm
The standard thickness is about 6 mm, and the thickness is about 6 mm. A top plate 10 is provided on the ceiling of the degassing section 3. The deaeration section 3 is connected to the inflow section 2 at the front in the direction of movement.
It communicates with the finishing part 4 at the rear. The standard width of the slit 9 is about 0.5 mm to about 3 mm. However, since the amount of deaeration is different between the vibration propagation zone and the non-vibration propagation zone, the width of the slit 9 is approximately 0.5 mm in the vibration propagation zone, based on experience.
mm to 1.5mm, approximately 1.5mm in non-vibration propagation zone
It is desirable to set it to about 3.0 mm. Furthermore, if an appropriate number of deaeration holes 11 are provided at appropriate locations on the strip plate 8 together with or in place of the slits 9, the deaeration efficiency will be further improved. In this case, from the viewpoint of preventing sand leakage and ensuring the deaeration function, the diameter of the deaeration hole 11 is set to about 0.5 mm to about 3 mm. In this case, since the amount of deaeration is different between the vibration propagation zone and the non-vibration propagation zone, the diameter of the deaeration hole 11 is approximately 0.5 mm to 1.5 mm in the vibration propagation zone, and approximately 1.5 mm to 3.0 mm in the non-vibration propagation zone. It is desirable to keep it at a certain level. When the slit 9 and the deaeration hole 11 are expanded outward as shown in FIGS. 3 and 4, it becomes easy to remove the solidified cement portion after the slit flows out, and the function is to prevent clogging and deaeration. It is desirable from the viewpoint of securing The expansion degree θ is arbitrary. In the illustrated example, the degree of expansion θ is approximately 90°. The finishing section 4 is composed of flat plates 12 parallel to the direction of movement of the machine body, and is formed at the rear end of the formwork 1 so as to be continuous with the degassing section 3. The ceiling of the finished part 4 has an extended top plate 10, and the rear end is open. The deaeration section 3 and finishing section 4 constitute a molding section 13 of the formwork 1. The bottom 1a of the formwork 1 is open. However, because of the above configuration, the molding section 13
When fresh concrete is actually poured, it becomes a sealed structure. From the perspective of ensuring deaeration and backfilling, the horizontal length ratio of the finished part 4 and the degassing part 3 is 70% to 80% in the degassing part 3 and 30% in the finished part 4, based on experience. It is desirable to set it to about 20%. Reference numeral 14 designates a tray receiving gutter, 15 a tray receiving tray, 16 a superstructure member, 17 a supporting member, and 18 a vibrator. In this example, the radius from the center of the vibrator 18 is
A vibrator 18 is installed so that vibrations are propagated within a range of about 200 mm.

In the molding work of the concrete structure according to the present invention, from the inlet 7 through the inflow part 2 to the molding part 1.
The concrete poured into the container 3 is filled with fluidity while receiving vibration propagation from the vibrator 18 at the lower part of the inlet part 2 and the front part of the degassing part 3.
It is molded in the degassing section 3. In a concrete structure formed in this manner, air from deep inside gradually rises to the surface due to vibration propagation. Since this air floats in all directions, the air reaching the side surface of the deaeration section 3 is discharged to the outside through the slit 9 or the slit 9 and/or the deaeration hole 11. Degassing from the slit 9 or the slit 9 and/or the degassing hole 11 is naturally carried out not only for the air floating up from the inner core but also for the air present at the surface. During this deaeration, the surface of the concrete structure is roughened in the form of scars. by the way,
As the air floats up, a liquid cement portion of the ready-mixed concrete, called a doro, flows out from the slit 9 or the slit 9 and/or the deaeration hole 11. Since the dust is immediately applied and evenly distributed on the surface by the flat plate 12 of the finished part 4 provided continuously to the deaeration part 3, no deaeration traces are formed on the surface of the concrete structure. Therefore, in the molding work of the concrete structure according to the present invention, post-process work to finish and correct some unevenness, collapse, etc. is performed approximately 10 to 20 minutes after the completion of the series of mechanical molding work described above. It becomes much easier.
