Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a live-container placement vibrator that vibrates the live-cone in order to fluidize the live-cone that has flowed into the mold when placing the live-container or to evacuate internal air, and a vibrator hose used therefor.

Conventionally, when placing a ready-mixed concrete, vibration is applied to the ready-mixed concrete (fresh concrete) that has flowed into the formwork, thereby fluidizing the ready-mixed concrete and extracting (purges) air mixed in the ready-mixed concrete. ing.
In this way, the ready-mixed concrete poured into the mold can be made to vibrate by applying vibration to the ready-mixed food, so that it can be filled into every corner of the mold.
Moreover, by giving vibration to the raw control unit, it is possible to drive out air mixed in the raw control unit and prevent generation of a cavity caused by the air solidifying while mixed in the raw control unit.

Conventionally, a high-frequency vibrator (vibration frequency is, for example, 200 to 240 Hz) that vibrates a vibrating body inserted into the live-container at a high frequency is widely used as a component that gives vibration to the live-con poured into the mold.
For example, Patent Document 1 below discloses a high-frequency vibrator for placing this type of live-con.

However, in the case of this high-frequency vibrator, if the reinforcing bars are closely assembled, there is a problem that even if the high-frequency vibrator is vibrated at a high frequency, the raw concrete cannot be sufficiently fluidized.
For example, as shown in FIG. 7, when the vertical hole 200 that is as deep as 150 m deep in the ground is drilled, the concrete wall 202 that constitutes the hole wall needs to have extremely strong strength. In such a concrete wall 202, as shown in FIG. 7B, the reinforcing bars 204 are densely incorporated.

  In this case, even if a high-frequency vibrator is inserted into the interior surrounded by the reinforcing bars 204 and 204 and vibrates, the vibration exceeds the reinforcing bars 204 and sufficiently reaches the internal raw material surrounded by the other reinforcing bars 204 and the reinforcing bars 204. It does not propagate, and the vibration is attenuated quickly, so that the whole raw concrete does not vibrate well, so even if a highly fluid raw concrete is used, the raw concrete does not sufficiently fluidize and the inside of the mold Insufficient filling of raw concrete into the tank will occur, or air bleeding will be insufficient.

The cause is considered to be due to the small amplitude in the case of high-frequency vibrations. Therefore, in such a case, it is more effective for the operator to hold the stick, push it into the raw control unit, and repeatedly perform the pushing action.
However, when the hole wall 200 is large (for example, when the hole diameter is as large as 10 m), a very large number of workers hold the sticks in their hands at the same time and poke the raw control. Is difficult to realize.

Therefore, there has been a demand for a vibrator for placing a live-con that can sufficiently vibrate the entire raw-container even when the reinforcing bars 204 are closely assembled, and can fluidize it satisfactorily.
As a prior art to the present invention, Patent Document 2 discloses an invention relating to a rubber expansion tube unit using a flat rubber hose.
However, the one disclosed in Patent Document 2 is common to the present invention in that a rubber hose is used, but is different from the present invention in its usage and configuration.

JP-A-10-292628 JP-A-2005-104646

  The present invention is based on the circumstances as described above, and even when the reinforcing bars are densely assembled, the raw control unit that can give good vibration to the raw control unit poured into the mold It is made for the purpose of providing the vibrator for vibrators and the vibrator hose used for this.

  Thus, Claim 1 relates to a vibrator for driving a live concrete, and a vibrator hose including a rubber hose is inserted into a live concrete poured into a mold, and the vibrator hose is inserted by introducing a fluid into the vibrator hose. It expands in the direction perpendicular to the hose axis and contracts in the direction of the hose axis, and by discharging the fluid, the vibrator hose contracts in the direction perpendicular to the axis and extends in the direction of the hose axis. A vibration is imparted to the raw food container by repeating it alternately.

  Claim 2 relates to a vibrator hose, which is a vibrator hose which is inserted into a raw concrete poured into a mold and gives vibration to the raw concrete, wherein (a) a rubber hose and (b) a tip of the rubber hose are closed. A distal end member attached to the distal end of the rubber hose so as to protrude from the rubber hose in the hose axial direction; and (c) an inside of the rubber hose attached to a proximal end opposite to the distal end of the rubber hose. And an end member having a fluid inlet, and the rubber hose is free-form and has a flat cross-sectional shape.

  According to a third aspect of the present invention, in the second aspect of the present invention, the tip member has a circular cross-sectional shape and a shape that gradually decreases in diameter toward the tip.

  According to a fourth aspect of the present invention, there is provided the vibrator hose according to any one of the second and third aspects, wherein the vibrator hose is inserted vertically and downward in a suspended state in the raw concrete, and the tip member is made of a metal material. The tip member forms a weight.

  A fifth aspect of the present invention is the vibrator hose which is inserted into the raw concrete in a horizontal direction according to any one of the second and third aspects and extends in the axial direction of the hose inside the rubber hose so that the shape of the rubber hose is linearly maintained. A rigid core member is provided.

  According to a sixth aspect of the present invention, in the fifth aspect, the tip member is made of a resin material.

Effects and effects of the invention

  As described above, the vibrator for placing a live-con according to claim 1 inserts the vibrator hose including the rubber hose into the live-con poured into the formwork, and introduces the vibrator hose in the direction perpendicular to the axis by introducing the fluid into the vibrator hose. The vibrator hose is contracted in the direction perpendicular to the axis by expanding and contracting in the axial direction of the hose, and extended in the direction of the hose axis by discharging the fluid.

  In the vibrator for placing a live-con according to claim 1, the vibrator hose can be expanded and contracted slowly and largely in the direction perpendicular to the axis at a low frequency (5 to 10 times / min). It can be contracted and extended slowly and greatly in the axial direction.

By repeating this, vibration can be applied in the direction perpendicular to the axis and in the direction of the hose axis with a large amplitude to the raw material inside the mold, and even if the reinforcing bars are closely assembled, the raw material can be effectively fluidized. In other words, it is possible to fill the raw concrete into every corner inside the mold.
At the same time, the air mixed in the live control can be driven out of the live control and extracted with the large vibration.

  Claim 2 relates to a vibrator hose used for the vibrator for driving a live concrete, and a rubber hose and a tip member attached to the tip part in a state of closing the tip part and protruding from the rubber hose in the hose axial direction. And an end member having a fluid inlet to the inside of the rubber hose mounted on the opposite base end portion, and forming a vibrator hose, and the rubber hose is in a free shape state and the cross-sectional shape is flat It was made to become.

  As the vibrator hose in the vibrator for placing a live-con according to claim 1, it is possible to use one having a circular cross-sectional shape, but when the cross-sectional shape of the rubber hose is made flat according to this claim 2 When a fluid is introduced inside and expanded in a direction perpendicular to the axis, the cross-sectional shape is larger than that of a rubber hose having a circular shape. Therefore, compared with the case where a rubber hose having a circular cross section is used, it is possible to give a large vibration to the raw concrete more effectively.

In addition, in the case of a rubber hose with a circular cross-sectional shape, the entire outer peripheral surface expands evenly in the direction perpendicular to the axis when expanded in the direction perpendicular to the axis. Greatly expands in the direction perpendicular to the axis with respect to the other part, and the outer peripheral surface of the rubber hose causes uneven movement in the direction perpendicular to the axis between the flat part and the other part.
And the non-uniform movement makes it possible to effectively stir and flow the ready-mixed rice and promote the flow of the ready-made food.

In the vibrator hose according to claim 2, the tip member attached to the tip of the rubber hose is provided in a state of protruding from the rubber hose in the hose axial direction. When it extends | stretches later, a rubber hose can pierce | push well in a raw hose by the front-end | tip member in the hose axial direction.
The movement of the rubber hose, that is, the vibrator hose at this time is the same as if the operator thrusts the stick into the raw control.

In this case, the tip member may have a circular cross-sectional shape and a shape that gradually decreases in diameter toward the tip.
In this case, there is an advantage that the tip member has a bullet-like shape and can be pushed into (inserted into) the raw control with less resistance.

The vibrator hose of the present invention can be used in a state where the vibrator hose is inserted vertically and downward in a suspended state in a living concrete.
In this case, the tip member can be made of a metal material (preferably an iron material), and the tip member can act as a weight (claim 4).
In this case, the tip of the rubber hose (ie, vibrator hose) can easily penetrate into the raw control when it extends in the axial direction of the hose, and can vibrate the raw control well in the vertical direction to exert a stirring action. It becomes.

  In the present invention, the vibrator hose can also be used by being inserted sideways into the biocon. In this case, a rigid core member is provided that extends in the hose axial direction inside the rubber hose and holds the shape of the rubber hose linearly. (Claim 5).

In this way, when the vibrator hose is inserted sideways into the raw control unit and vibrated, the rubber hose may be deformed such that the tip side of the rubber hose hangs down.
However, according to the fifth aspect, the drooping deformation can be prevented well by the shape holding effect by the rigid core member, and the vibration hose (vibrator hose) can be vibrated in a state where the rubber hose (straight vibrator) is extended straight sideways. Become.

In this case, the tip member can be made of a resin material.
When the vibrator hose is used sideways, if the tip is heavy, the tip tends to hang down. However, if the tip member is made of a light resin material according to claim 6, such inconvenience can be avoided.

The rubber hose 26 has a laminated structure of an inner rubber layer 28, a reinforcing layer 30, and an outer rubber layer 32.
Here, the inner rubber layer 28, the reinforcing layer 30, and the outer rubber layer 32 are integrally vulcanized and bonded.
The reinforcing layer 30 is formed by braiding reinforcing yarns made of chemical fibers (blade braiding, spiral braiding).

A tip member 34 is attached to the tip of the rubber hose 26, that is, the right end in the figure, and the tip of the rubber hose 26 is closed by the tip member 34.

Engagement teeth 40 having a sawtooth shape in cross section are formed on the outer peripheral surface of the insertion portion 36. The engagement teeth 40 bite into the inner surface of the rubber hose 26, thereby preventing the tip member 34 from coming off the rubber hose 26. Has been.

The protruding portion 38 protrudes from the distal end portion of the rubber hose 26 to the right in the drawing, that is, in the hose axial direction.
The projecting portion 38 has a bullet-like shape as a whole, more specifically a circular cross-sectional shape, and a shape that gradually decreases in diameter toward the right in the drawing, that is, toward the tip. Here, the tip has a round shape.
A metal fastening sleeve 42 is externally attached to the distal end portion of the rubber hose 26, and the distal end member 34 and the distal end portion of the rubber hose 26 are strengthened by tightening the fastening sleeve 42 in the diameter reducing direction. It is fixed.

A metal end member 44 is attached to the left end of the rubber hose 26 in the drawing, that is, the base end opposite to the distal end.
The end member 44 has a cylindrical portion 46, and the cylindrical portion 46 is fitted into the proximal end portion of the rubber hose 26.
Also in the end member 44, engagement teeth 40 having a sawtooth shape in cross section are formed on the outer peripheral surface of the cylindrical portion 46, and when the engagement teeth 40 bite into the inner surface of the rubber hose 26, The member 44 is prevented from coming off from the rubber hose 26.

Also at the base end portion of the rubber hose 26, a metal fastening sleeve 42 is extrapolated, and the end member 44 is firmly attached to the base end portion of the rubber hose 26 by tightening the fastening sleeve 42 in the diameter reducing direction. It is fixed.
The end member 44 includes a coupler 48, and the coupler 48 protrudes from the base end portion of the rubber hose 26 to the left in the drawing.
The end member 44 is provided with an inlet 50 for pressurized air at the center. The pressurized air is introduced into the rubber hose 26, that is, into the vibrator hose 12 through the introduction port 50.

In this embodiment, the rubber hose 26 has a length L of about 1 m.
Further, the rubber hose 26 is in a shape at the time of molding, that is, in a free shape, and most of the rubber hose 26 excluding a part of both end portions in the axial direction, that is, almost the whole part excluding a part near the tip member 34 and the end member 44 is traversed. It has a flat surface.
Specifically, the thickness dimension T shown in FIG. 2B is 15 mm, whereas the width dimension W is 80 mm.
In the present invention, it is desirable that the rubber hose 26 has a flat shape so that the thickness dimension T is at least 15 mm or less with respect to the width dimension W.

FIG. 3 shows a vibrator hose that is used by being inserted sideways in a raw concrete poured into the mold, and in the vibrator hose 12 of FIG. 3, a plate-like shape that extends in the hose axial direction inside the rubber hose 26. The metal rigid core body member 52 is provided.
Here, as shown in FIG. 3B, the core member 52 is integrally fixed with the left end portion thereof fixed to the cylindrical portion 46 of the metal end member 44.

  In the case of the vibrator hose 12 of FIG. 3 used in the lateral direction, the tip member 34 having the same shape as that shown in FIG. 2 is provided, but here the tip member 34 is made of a resin material, and the tip member 34 is a lightweight one.

Further, in the vibrator hose 12 shown in FIG. 3, since the core member 52 is provided inside the rubber hose 26, the thickness dimension T in the shape at the time of molding, that is, a free shape, is larger than that of the vibrator hose 12 shown in FIG. Slightly thicker.
In addition, about another structure, it is the same as that of the vibrator hose 12 shown in FIG. 2, Only a code | symbol is described in a corresponding part and detailed description is abbreviate | omitted.

FIG. 4 shows the action during the vibration operation of the vibrator hose 12.
As shown in FIGS. 2 and 3, the vibrator hose 12 has a flat shape when substantially the entire rubber hose 26 is in a free shape.
When pressurized air is introduced into the inside through the introduction port 50 under this state, the shape of the vibrator hose 12, specifically the rubber hose 26, changes due to the pressure from the inside.
Specifically, as can be seen from a comparison between (I) (A) and (II) (A) in FIG. 4, the rubber hose 26 expands in the direction perpendicular to the axis by the introduction of pressurized air, and the cross-sectional shape after expansion Becomes circular.
At this time, the rubber hose 26 expands in the direction perpendicular to the axis in the direction perpendicular to the flat surface and expands in the direction perpendicular to the axis, or does not change so much in the direction perpendicular to the axis at the both end portions in the width direction.

Whether the portions other than the flat surface, that is, both end portions in the middle width direction in FIGS. 4 (A) and 4 (A), expand in the direction perpendicular to the axis depends on the pressure of the pressurized air introduced into the rubber hose 26, that is, the expansion amount of the rubber hose 26. It depends on.
In any case, the expansion and deformation of the rubber hose 26 due to the introduction of pressurized air greatly increases the area of the internal cross section, and the rubber hose 26, that is, the live control around the vibrator hose 12 is largely eliminated in the direction perpendicular to the axis.

  On the other hand, when the internal air is discharged from the state shown in FIG. 4 (II), ie, the state where pressurized air is introduced into the interior and the rubber hose 26 is expanded in the direction perpendicular to the axis, the rubber hose 26 is restored by its own elasticity. At this time, the rubber hose 26 contracts and deforms in the direction perpendicular to the axis while it expands and deforms in the hose axial direction.

When the compressed air inside the rubber hose 26 is discharged to restore the rubber hose 26 to its original shape, not only the internal air is naturally discharged but also the internal air is forcibly sucked and discharged in some cases. You can also.
In this case, in addition to the restoring force of the rubber hose 26, a forced restoring force from the outside is applied, and the rubber hose 26 is forcibly forced inside the raw control regardless of the resistance of the raw control unit. It returns to the length of the original shape shown in (B), and at that time, the tip part is pushed into the hose axial direction with respect to the raw control.

When the introduction and discharge of pressurized air are alternately performed at a predetermined cycle with respect to the vibrator hose 12 as described above, the vibrator hose 12 has the shape shown in FIGS. 4 (II) and (A) are alternately and repeatedly deformed, and in the hose axial direction, the shape shown in FIGS. 4 (I) and (B) and FIGS. 4 (II) and (B). The shape changes alternately and periodically, and the vibrator hose 12 vibrates by periodically introducing and discharging pressurized air. And thereby, a large vibration with a large amplitude and a slow vibration is applied to the raw concrete poured into the mold.
In this embodiment, supply and discharge of pressurized air, that is, internal pressurization and decompression are performed so that the vibrator hose 12 repeats expansion and contraction alternately at a cycle of about 5 to 10 times per minute. .

5 and 6 show the actual action of the vibrator hose 12 shown in FIG. 2 and the vibrator hose 12 shown in FIG.
5 shows the operation of the vibrator hose 12 shown in FIG. 2, and FIG. 6 shows the operation of the vibrator hose 12 shown in FIG.

FIG. 5 shows that the vibrator hose 12 shown in FIG. 2 is inserted into the raw concrete K in a suspended state vertically and downward (54 in FIG. 5 indicates a rebar that is closely assembled at a pitch of 60 to 100 mm, for example). FIG. 5 (I) shows the action when the vibrator hose 12 is vibrated by expanding and contracting it by supplying and discharging pressurized air, that is, by internal pressurization and decompression. By changing the shape of the vibrator hose 12 in the shape of a flat shape as shown in FIG. 5 (II) by introducing pressurized air, the live control around the vibrator hose 12 is pushed out in the direction perpendicular to the axis.
Further, the vibrator hose 12 extends in the axial direction from the state shown in FIG. 5 (II) to the state shown in FIG. 5 (I) due to the internal pressure reduction, so that the vibrator hose 12 is protruded downward in the figure, and the raw concrete K is directed downward. Extruded.

By repeating this, vibration is applied to the raw concrete K in the direction perpendicular to the axis and the direction of the hose axis.
Since a heavy bullet-like metal tip member 34 is attached to the tip of the vibrator hose 12, when the vibrator hose 12 extends the hose shaft in the raw control K, it can be extended with little resistance, and the raw control The tip portion can be pushed into K, and vibration can be effectively applied to the raw concrete K in the hose axial direction.

  On the other hand, as shown in FIG. 6, the vibrator hose 12 shown in FIG. 3 is inserted laterally into the bio-container K (at this time, the base end side is fixed), and internal pressurization and decompression are periodically performed in this state. Even in the case of repeating alternately, vibrations are applied in the direction perpendicular to the axis (the vertical direction here) and the hose axis direction (here, the horizontal direction in the figure, which is the horizontal direction) with respect to the live control around the vibrator hose 12.

  In the vibrator hose 12 shown in FIG. 3 that is used sideways, the tip member 34 is made of a lightweight resin material. Further, in the vibrator hose 12 shown in FIG. Since the body member 52 is disposed and the vibrator hose 12 is linearly held by the core body member 52, it is satisfactorily suppressed that the tip end side hangs down.

  As described above, according to the present embodiment, the vibrator hose 12 is expanded and contracted slowly and largely in the direction perpendicular to the axis at a low frequency (5 to 10 times / min) and simultaneously contracted and contracted in the hose axis direction. By extending, vibration can be applied in the direction perpendicular to the axis and in the direction of the hose axis with a large amplitude with respect to the raw component inside the mold.

Therefore, even when the reinforcing bars are closely assembled, the raw concrete can be effectively fluidized and can be filled into every corner of the mold.
At the same time, the air mixed in the live control can be driven out of the live control and extracted with the large vibration.

  Further, in the vibrator hose 12 of the present embodiment, since the rubber hose 26 has a flat cross-sectional shape, the vibrator hose 12 is arranged in the direction perpendicular to the axis and in the hose axial direction as compared with the case where a rubber hose having a circular cross-section is used. It can be expanded and contracted greatly, and can effectively give a large vibration to the raw control.

  In the vibrator hose 12 of this embodiment, the tip member 34 is attached to the tip of the rubber hose 26 in a protruding state in the hose axial direction, and the tip member 34 has a bullet-like shape. When the hose 12 is extended from the contracted state, the vibrator hose 12 can be pushed forward (intruded) into the raw concrete by the tip member 34.

  Further, in the vibrator hose 12 of FIG. 2 that is used in the state of being inserted vertically in the suspended state and in the downward direction in the raw concrete K, the tip member 34 is made of a metal material (preferably an iron material). This can be used as a weight.

On the other hand, in the vibrator hose 12 shown in FIG. 3 that is used by being inserted sideways into the raw concrete K, the rubber hose 26 is provided with a rigid core member 52 that holds the shape of the rubber hose 26 in a straight line. It is possible to satisfactorily prevent the drooping deformation from being caused by the shape retaining effect of the core member 52, and the vibrator hose 12 can be vibrated in a state where the vibrator hose 12 is turned sideways.
Further, in this case, since the tip member 34 is made of a light resin material, it is possible to prevent the tip side from hanging more favorably.

  Although the embodiments of the present invention have been described in detail above, these are merely examples, and the present invention can be configured in various modifications without departing from the spirit of the present invention.
