DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a precast concrete unit having a display function, a buried display body suitable for the unit, and a buried display holder.

[0002]

2. Description of the Related Art Concrete stakes or columns for burial with a display function, such as display piles and boundary piles for displaying objects buried in the ground such as electric wires and pipes, and bollards for reflecting lights, or other objects. A wide variety of concrete products are prepared for the purpose. For display piles that display embedded objects such as electric wires and pipes, water,
Since it is necessary to display the types of buried objects such as sewage, gas, high voltage, and low voltage, the pipe diameter, and also the branch direction of the pipes, the types of display piles to be prepared are enormous,
If the display method is different depending on the region or jurisdiction, the number of types is further increased.

[0003] In these display piles, if the display portion deteriorates with age and cannot be distinguished, the original purpose cannot be achieved. Therefore, the display contents are not added by painting or sealing, but the form is adjusted according to the display contents. It is processed so that the display contents are represented by irregularities on the concrete surface.

[0004]

These display piles and boundary piles are precast by using a formwork processed in accordance with display contents. For this reason, as the contents to be displayed on display piles, boundary piles, etc. increase, these piles are likely to be produced in a large variety of small quantities, it takes time to manufacture at the factory, and it is difficult to deliver them to the site in a timely manner. With it becomes very expensive. Even if such products are mass-produced, they require space for inventory and manpower for management, so they are not inexpensive. Reflecting it makes it even more expensive.

[0005] It is possible to reduce the cost of a display pile or the like by separately manufacturing a display body in accordance with the diversified display contents and attaching the display body at a site or a factory or attaching with a concrete nail or the like. However, it is hard to say that this is a very effective method in view of the labor required for bonding and nailing, and a decrease in reliability such as subsequent dropout. Although it is possible to bury the display body in display piles, etc., when pouring concrete into the formwork, the position will shift or the display surface will be covered with concrete and it will not be able to function as a display body. It is not possible to supply inexpensive and stable products with high frequency of failures.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a buried-type display body capable of reliably burying a display body at a predetermined position and a precast concrete unit having the display body buried therein. Still another object of the present invention is to provide a buried display body capable of more flexibly coping with a variety of display contents, a precast concrete unit in which the buried body is buried, and a method of manufacturing these units.

[0007]

For this reason, according to the present invention, a projection is provided for attaching the display body to a predetermined position of the mold, and the projection is fitted into a hole of the mold so that the display body is formed in a predetermined shape. , And concrete is injected, and then the mold can be easily removed by the same procedure as a concrete unit without buried objects. That is, the embedded display body of the present invention has an embedded body having a display surface exposed on the surface of the concrete unit, and at least one projection protruding from the display surface, and the projection forms the concrete unit. It is characterized in that it can be fitted into a setting hole provided in a mold. By inserting and fixing the projections protruding from the display surface into the setting holes, the embedded body can be set at a predetermined position and the display surface can be pressed against the surface of the mold. For this reason,
It is possible to bury a buried type display body having a display surface at a predetermined position at the time of precasting, and further, it is possible to bury the display body so that the display surface is surely exposed after manufacturing. In addition, since the buried display may be changed in order to change the display content, the mold can be used in common. Therefore, it is possible to reduce the cost required for processing the formwork, and it is possible to flexibly cope with a change in display contents. As described above, by using the buried type display body of the present invention, a predetermined display can be provided at a predetermined position of a precast concrete unit without any trouble, and a variety of displays can be provided. Concrete units can be supplied very inexpensively and in a short time.

Further, the projection can be cut when the concrete unit is removed from the mold. Accordingly, a step of fitting the protrusion protruding from the buried type display body into a setting hole provided in the manufacturing formwork of the concrete unit to set the buried type display body at a predetermined position of the manufacturing formwork; Following the step of injecting concrete into the frame, a concrete unit having a display function is manufactured by using the concrete unit having no buried object and the step of removing the concrete unit from the production form in the same procedure. be able to. Ie display
Buried display body with surface was buried during precast
It is a concrete unit and the display surface is exposed
At least one protruding from its display surface
Characterized by having a projection or a trace of it being cut
A concrete unit can be provided .

With such a buried display and a concrete unit, a concrete unit having a display function can be supplied at low cost in a short period of time.
Further, in order to cope with various display styles, in the present invention, instead of directly embedding the display body in the concrete unit, a buried type display body holder having a holder portion into which the display body can be fitted is made of concrete. It is buried in a unit so that an appropriate display body can be easily attached to a concrete unit at an appropriate time at a site or the like.
That is, the embedded display body holder of the present invention has an embedded body provided with a holder portion exposed on the surface of the concrete unit, and the holder portion includes a frame body into which a plate-type display body can be fitted, and a frame body. And a mounting part surrounded by a body. The concrete unit buried so that the holder part of the buried type display body holder of the present invention is exposed can be fitted in any display body at a convenient place at a convenient time.
High versatility. Therefore, mass production is possible, and product inventory management is easy, so that it is possible to supply the product at very low cost and to deliver it to the site in a timely manner.

[0010] Such a buried display holder can be made detachable by fitting the frame into a setting boss provided on a mold for molding a concrete unit. Therefore, a step of setting the embedded display body holder at a predetermined position of the production form by fitting into the setting boss, a step of injecting concrete into the production form, and a direction in which the setting boss extends from the production form. A concrete unit to which a display function can be easily added can be manufactured by using the step of removing the concrete unit from the mold.

Further, similarly to the above-mentioned buried type display, at least one projection protruding from the surface of the frame or from the mounting portion is provided, and this projection is provided on a mold for molding a concrete unit. It is also possible to set by fitting into the hole. Further, it is possible that the projection can be cut when the concrete unit is released from the mold. Therefore, the buried-type display body holder can be set in the form using the setting holes, and the mold can be easily removed in the same process as a concrete unit having no buried object. Since the holes prepared in the mold for fitting the projections may have a small diameter, the processing of the mold is easy and the position of the holes can be easily changed. In addition, since the same concrete unit can be used for different display contents, it is not necessary to change the formwork, and a concrete unit having a display function can be provided at very low cost.

[First Embodiment] FIG. 1 shows an outline of an embedded display having a reflection function according to the present invention. The buried display 10 of this embodiment is made of a plate-shaped plastic, and has a buried body 13 having a rectangular base 11 buried in concrete and a display 12 formed on the surface side of the base 11. The display 12 is diamond cut so as to reflect light and the like. The base 11 is wider than the display body 12, and when the buried body 13 is buried in the concrete so that the surface 12a of the display body 12 is exposed from the concrete, the base 11 is completely buried in the concrete and removed. The buried body 13 is prevented from falling off the concrete when molding or when a concrete product is used.

In the buried display 10 of this embodiment, two diagonal corners of the surface (display surface) 12a of the display 12 are
The projections 30a and 30b of the book are formed so as to project in a direction perpendicular to the display surface 12a. As will be described later, by using these projections 30a and 30b, the buried-type display body 10 of this example can be set as a formwork for manufacturing a concrete product. At this time, the display surface 12a of the display body 12 Can be attached to the formwork so as to press against the inner surface. The protrusions 30a and 30b are made of plastic and are formed in a shape in which ribs 33 each having a thickness of about 1 mm are combined in a cross shape, and have a diameter of about 2 to 5 mm and a length of about 5 to 10 mm. The size of the protrusion 30 is not limited to this example, and can be changed according to the size and weight of the embedded body 13 or the thickness of the mold. Also,
The shape of the projection 30 is not limited to the four ribs combined in a cross shape as in this example, but may be a combination of three or less or five or more ribs. Further, it is also possible to adopt a projection having a cylindrical or columnar shape. The number of projections is preferably two or more in order to stabilize the setting direction, and may be three or more. In addition, the size of the projection can be changed according to the number of projections provided on the embedded display body 10. further,
The position where the protrusion 30 is formed is not limited to the two corners of the display body 12 as in this example, but may be provided at four corners, or the protrusion 30 may be formed near the center of the display surface 12a of the display body. good. Further, it is desirable that the protrusion 30 be set to a size that can be easily cut when the mold is removed, and it is also possible to provide a groove or a cut at the boundary between the protrusion and the display surface so that the protrusion 30 is easily cut.

FIG. 2 shows a block 1 for stopping a vehicle in a parking lot as an example of a concrete unit using the buried display 10 of this embodiment.
The car stop block 1 of this example is a concrete block having a substantially trapezoidal cross section that is long in the horizontal direction, and a substantially vertical recess 2a is formed on a part of a slope 2 that is inclined so as to be easily in contact with a vehicle tire. The buried display 10 is buried in the recess 2a. Block 1 for car stop in this example
Is a precast product prefabricated at the factory,
A buried display 10 is formed integrally with a vehicle stop block (concrete unit) 1. Therefore, the buried display body 10 does not separate or peel off from the concrete unit 1 even when the car stop block is constructed or used thereafter, and the product is highly durable and reliable. Also, by embedding the buried display body 10 in the recess 2a at an angle close to substantially vertical, the headlight or backlight of the vehicle is efficiently reflected toward the driver by the display surface 12a having a reflection function. Therefore, the position of the block for a vehicle can be clearly shown even at night.

A process of manufacturing the vehicle stop block 1 according to the present embodiment will be described with reference to FIGS. The car stop block 1 of the present embodiment is formed using a durable formwork 40 made of a durable material such as iron as shown in FIG. Formwork 40 of this example
Is provided with a convex portion 41 for forming the recess 2a of the vehicle stop block 1, and this convex portion 41 is formed with two setting holes 42a and 42b. As shown in FIG. 6 in an enlarged manner, the projection 41 has a display surface 1 of the embedded display body 10.
A flat surface 41a slightly wider than 2a is provided, and two setting holes 42a and 4 are formed at diagonal corners of the flat surface 41a.
2b is provided. The positions of the setting holes 42a and 42b correspond to the protrusions 30a and 3 provided on the embedded display body 10.
0b, and setting holes 42a and 42b
Has a size that allows the protrusions 30a and 30b to be fitted. Further, the fitting tolerance between the setting holes 42a and 42b and the projections 30a and 30b is set to a close fit or a range of the close fit. For this reason,
When the projections 30a and 30b are inserted into the setting holes 42a and 42b, the embedded display body 10 can be set at a predetermined position of the mold 40.

Further, as shown in FIG.
When the projections 30a and 30b are inserted into and 42b,
The display surface 12a can be brought into close contact with the plane 41a of the mold. For this reason, when the concrete is poured into the formwork 40, the concrete or the slack of the concrete is displayed on the display surface 12a.
And the flat surface 41a.
The embedded display 10 and the concrete unit 1 can be integrally precast so that 2a is reliably exposed from the surface of the concrete.

As shown in FIG. 4, after setting the buried type display body 10 on the convex portion 41 of the mold 40, concrete 19 is poured into the concrete block 1 to bury the buried type display body 10 therein. Can be molded. In the buried display 10 of this example, since the projections 30a and 30b are provided on the display surface 12a of the display 12, the projections 30a and 30b are simply inserted into the setting holes 42a and 42b. Can be set at a predetermined location of the mold 40, and the buried display 10 can be prevented from moving even when concrete is poured. Further, by aligning the projections 30a and 30b with the setting holes 42a and 42b, the display surface 12a faces the inner wall of the mold frame 40, and the direction and the inclination of the display surface 12a become constant.
It is possible to easily and reliably manufacture a high-quality concrete block 1 in which the position, angle, direction, and the like of a are constant. In the buried display 10 of this example, the base 11 extending outward from the display 12 is buried in the concrete, so that the adhesion between the buried body 13 and the concrete can be sufficiently ensured. Therefore, there is no fear that the embedded display body 10 will fall out of the concrete block 1 when it is removed from the mold, which will be described later, or that the embedded display body 10 will peel off or fall off from the concrete unit 1 during construction or during subsequent use. It is possible to provide a highly reliable block 1 for a vehicle stop.

FIG. 5 shows a state in which the block 40 for the vehicle stop is formed from the mold 40.
Is shown. FIG.
The figure shows a state in which the mold 40 and the block 1 for car stop are vertically separated and demolded by turning by 80 degrees and using gravity. As shown in the drawing, when the car stop block 1 is released from the mold frame 40, the cutting force applied to the boundary between the projections 30a and 30b and the display body 12 when the vehicle stopping block 1 is released, and the embedded die embedded in the block 1 is removed. The projections 30a and 30b are cut from the display surface 12a of the display body 10. For this reason, the block 1 for car stops of this example can be removed in the same procedure as a concrete block having no buried object, and can be manufactured very easily. Further, the protrusions 30a and 30b remaining on the side of the mold 40 can be easily removed by using a wire or the like, and the next buried display 10 can be set immediately. Furthermore, since the buried type display body 10 of this example is formed of a resin such as plastic, including the projections 30a and 30b, the form frame 40 is not damaged, and the same form frame 40 can be used many times. The block 1 for a vehicle stop can be manufactured.

In order to bury a display board when a concrete block is precast at a factory by a method other than this example, the display board is fixed to a mold by screws or the like, or an adhesive is used. A method of sticking the display plate to the formwork can be adopted. The method of fixing the display panel to the formwork with screws, etc., takes time when mounting the display panel to the formwork, and furthermore, it is necessary to remove the screws that attached the display panel to the formwork before removing the mold. Was. Therefore, the operation takes time and costs are increased, and if there is an error in mounting or removing the screw, the concrete unit or the buried display body is damaged, so that the loss is large. On the other hand, in the method of attaching the display panel to the formwork, it is difficult to obtain a large adhesive force because the release material such as oil is applied to the surface of the formwork. It is very unstable, for example, the display panel cannot be exposed because it runs slowly. In addition, it is troublesome because it is necessary to clean the trace of the adhesive after removing the mold. As described above, embedding a display board when precasting a concrete block is very time-consuming, increasing the cost and, at the same time, it is difficult to bury the display board securely in a predetermined position. Not done. On the other hand, it is also possible to adopt a method in which a display panel is attached to the surface of a concrete block with an epoxy resin or the like on the precast concrete unit, or the display panel is nailed using a concrete nail. However, these methods are also troublesome, and are liable to cause troubles such as peeling or falling off of the display panel. Therefore, when the notation is definitely required on the surface of the concrete unit, a method is employed in which the formwork itself is processed according to the notation, and the surface of the concrete is formed and displayed. For this reason,
As described above, as the notation becomes more diverse, various types of formwork are required, and the production management becomes difficult, so that the concrete product is very expensive.

On the other hand, the embedded display 10 of this embodiment
Are setting holes 42a and 42 provided in the mold 40 in advance.
simply insert the projections 30a and 30b into the display body 1
0 can be set to a predetermined position, which saves time and trouble, and even when concrete is poured, there is no displacement and no slack of concrete goes around the surface. In addition, when removing the mold, the protrusions are automatically cut, so it can be easily removed with the same effort as a concrete block without a buried body, and there is a risk of damage to the formwork and concrete block due to mistakes. Not at all. Furthermore, since the formwork does not require any effort, it can be used many times,
Cleaning is also very easy. Further, since the embedded display body 10 and the concrete unit 1 are buried in the concrete at the time of precasting and integrated with the concrete unit 1, there is no problem such as peeling or falling off at the time of construction or use. Furthermore, by changing the notation of the resin-made buried type display body embedded in the concrete unit 1, the functions and notations added to the concrete unit 1 can be easily changed. Therefore, by standardizing the size of the display surface 12a of the various buried type display bodies 10 and the positions and sizes of the protrusions 30a and 30b, the same mold 4
The indicator 10 having a different notation can be embedded in the concrete unit 1 by using 0. Therefore, concrete units having different notations and functions can be mass-produced in the same mold, and the production efficiency of the mold can be greatly improved.
As described above, by adopting the embedded display body 10 of the present embodiment, it is possible to manufacture concrete units having different notations and functions at a low cost in a short period of time. in this way,
By the present invention, for the display of buried objects that will be further diversified in the future,
Alternatively, it is possible to provide a buried display body and a concrete unit suitable for various types of concrete blocks such as boundary piles and wheel stops.

As described above, in this embodiment, the description is made with reference to an example of a vehicle stopping block in which an embedded display body having a reflecting function is embedded. However, the present invention is not limited to the reflecting function.
It is possible to apply the present invention to all products that have conventionally been processed and processed with a concrete surface, such as blocks for display indicating the contents and positions of buried objects and blocks for boundaries. Concrete products can be provided at low cost in a short period of time.

[Second Embodiment] FIG. 8 shows a second embodiment of the present invention.
FIG. 9 shows an outline of the embedded display body holder according to the embodiment, and FIG. 9 shows the configuration of the embedded display body holder of the present example using a cross section. Buried display holder 2 of this example
Numeral 0 denotes a molded plastic article, which comprises a substantially square plate-shaped base 21 and an embedded body 23 composed of a holder 22 formed on the base 21. The holder 22 has four sides of the base 21. And a mounting portion 25 surrounded by the frame 24. An approximately square thin space is secured in the mounting portion 25, and a plate-type display body can be fitted therein. The frame body 24 is formed so as to frame along four sides of the mounting portion 25, and the upper portion of the mounting portion 25 so as to hold a plate-type display body (display plate) mounted on the mounting portion 25. Claw part 24 which slightly protruded
a. A step projecting toward the inside of the mounting portion 25 is formed inside the mounting portion 25 by the claw portion 24a, so that the display plate can be held.
Further, a gap 21a is provided on the back surface of the frame 24 so that the buried display holder 20 having such a shape can be made of plastic having a substantially constant thickness. Further, since the frame body 24 is formed inside the base 21, a step is formed on the outer periphery of the buried body 23, and when this is buried in the concrete, a sufficient adhesive force with the concrete unit is provided. It can be secured.

In the buried display holder 20 of this embodiment, four projections 30a to 30d further project upward (in the direction of the holder 22 with respect to the base 21) from the four corners of the frame 24. With these projections 30a to 30d, the embedded display body holder 20 can be set in a state where the frame body 24 is in close contact with the mold for manufacturing a concrete unit. Accordingly, it is possible to precast a concrete unit having the holder portion 22 of the buried type display body holder 20 exposed on the surface at the factory, and fit the display plate into the mounting portion 25 of the holder portion 22 at the site or the like. Can be. The configuration of each of the projections 30a to 30d is substantially the same as that described in the above embodiment, and the detailed description is omitted. In addition, as described above, the shape and size of the protrusion are not limited to this example, and the size, the number, and the shape more suitable for the size of the display body holder 20 can be similarly selected. .

FIG. 10 shows the buried display holder 2 of this embodiment.
The display stake 5 is shown as a concrete unit employing 0. The display pile 5 of the present example is a prism having a substantially square cross section, and has an embedded display body holder 20 of the present example on a surface (heaven) 6 that faces upward when buried in the ground in the vertical direction.
Is buried. The display pile 5 of the present example can attach a display plate to the mounting portion 25 of the embedded display body holder 20 even after the display pile 5 is buried, and by using the standardized mounting portion 25 and the display plate, the same display plate can be used. The display pile 5 in the form can be used for various purposes.

FIGS. 11 and 12 show an example. In this example, a state is shown in which the display plate 9, which is made of stainless steel and indicates the branch direction of the gas pipe, is set on the mounting portion 25 of the buried display holder 20. If the display pile 9 of this example prepares the display plate 9 with various notations beforehand, the embedded type display embedded in the display pile 5 immediately before or immediately after the display pile 5 is embedded at the site. The display plate 9 can be set on the attachment portion 25 of the body holder 20, and the display of the branch direction of the gas pipe and other indications about the buried object can be easily given. Further, since the display plate 9 and the mounting portion 25 in this example are substantially square, the direction in which the display plate 9 is set can be freely adjusted according to the direction in which the display pile 5 is embedded. The display plate 9 is formed in a size standardized in accordance with the size of the mounting portion 25, and is inserted into the mounting portion 25 or struck from above the frame 24 with a simple jig such as a plastic hammer. It can be easily installed. Once set on the mounting portion 25, the claw portion 24a of the frame body 24
Therefore, the display plate 9 can be permanently attached to the display stake 5 because it is not detached because it is held from the front side. In addition, the buried type display body holder 20 of the present example is used.
Is made of weather-resistant plastic, and since the display plate 9 is made of stainless steel, the display plate 9 has excellent weather resistance and can reliably display the buried object for a long period of time. It is of course possible to use a resin plate such as plastic as the display plate 9.
Even if a label printed on an aluminum foil or the like is laid in the inside and a transparent acrylic plate is fitted into the mounting portion 25 from above, an appropriate display can be given to the display pile 5.

The projections 30a to 30a projecting from the frame 24
30d is designed to be automatically cut when the mold is removed from the formwork, and the frame 24 of the display body holder 20 embedded in the surface 6 of the display pile 5 is a mark where the projection is cut. 3
Only one remains. When the projections 30 remain without being cut when the mold is removed from the mold, the remaining projections can be easily cut using a nipper or the like.

The display plate 9 shown in FIGS. 11 and 12 is merely an example. In addition, tap water, drainage, sewage,
Separation of sewage, gas, etc., pipe size, pipe material, pipe direction / branch, or presence / absence of valves, as well as discrimination of buried wires such as high voltage, low pressure, weak electricity, communication, etc. A wide variety of display plates can be prepared, such as site boundaries, boundary directions, and survey points. These display plates can be easily provided with a permanent notation by etching or the like, so that they can be supplied at a low cost, and the contents of the notation can be easily changed. It is easy to change the notation according to the standard. When a transparent plastic plate or the like is used, a more durable notation can be given by engraving characters or the like from the back side that fits in the mounting portion 25 of the holder portion 22.

In the display pile 5 of this embodiment, since the buried display holder 20 is integrally formed, any of the various display plates as described above can be mounted on the holder mounting portion 25. Therefore, except for the length of the pile, etc., by mass-producing and supplying one type of display pile 5,
It is possible to correspond to all sites, and it is possible to supply display piles at low cost when the sites require. Also,
Since the display pile of this example is very versatile, it can be marketed to general users. In addition, by mounting a plate whose name is described by weather-resistant paint or the like instead of the ready-made display plate, the display plate can be used for many more purposes.

FIGS. 13 and 14 show how the display pile 5 of this embodiment is manufactured. The display pile 5 of this example is precast at a factory using the same durable formwork 40 as in the above embodiment. 13 and 14 show a vertically elongated formwork 4 with the display pile surface 6 down.
0 shows how the display pile 5 is manufactured. FIG.
As shown in FIG. 3, the manufacturing formwork 40 of the present example has a setting hole 42 corresponding to each projection 30 of the embedded display body holder 20 in the bottom plate 43 facing the surface of the display pile.
Is open. These setting holes 42 and projections 30
Similar to the above-described embodiment, it is formed with a close fit or a close fit tolerance, and the embedded display body holder 20 can be fixed to the bottom plate 43 simply by inserting the projection 30 into the setting hole 42. Further, since the projections 30 are formed on the surface of the frame 24 of the display body holder 20, when the projections 30 are inserted and fixed in the setting holes 42, the frame 24 comes into close contact with the bottom plate 43 of the mold, and the holder is attached. The concrete and the back of the concrete do not enter the part 25. By setting the embedded type display body holder 20 of the present embodiment to the formwork 40 and then injecting the concrete 19, a display pile in which the embedded body 23 is embedded and integrated can be manufactured.

As shown in FIG. 14, after the concrete 19 is cured after curing, the formwork is rotated by 180 degrees and the display pile 5 is removed from the formwork 40. The projection 30 is cut off by the force applied to the boundary with the projection 43 and remains on the bottom surface 43 of the mold, or the projection 30 comes out of the setting hole 42 together with the display body holder 20. In any case, since the display body holder 20 is integrated with the display pile 5 and removed from the mold 40, the display pile 5 of the present example is removed in the same procedure as the display pile 5 having no buried object. be able to. Therefore, as in the case of the concrete unit described in the above-described embodiment, the demolding operation does not take much trouble, the display pile 5 can be manufactured with a low yield with less trouble in the construction, and the display pile 5 can be manufactured very inexpensively. Can be supplied. Also, in the display body holder 20 of this example,
Since the base 21 extends outward from the holder 22, when the display body holder 20 is buried in the display pile 5, the base 21 is caught by concrete. For this reason, since the display body holder 20 is buried with a sufficient adhesive force, it is difficult to peel off from the display pile 5, and the display body holder 2 is used at the time of removing the mold, installing the work, or attaching the display plate 9.

FIGS. 15 and 16 show how the display pile 5 of this embodiment is manufactured by using a horizontally elongated mold 40. FIG. In the formwork 40 of this example, the surface 6 of the display pile 5
A setting hole 42 is provided for inserting and fixing the projection 30 to the side wall 44 facing the side. Therefore, just by inserting the projection 30 into these setting holes 42, the display body holder 20 is
0 can be attached to a predetermined position. Further, since the frame 24 is in close contact with the side wall 44, it is possible to prevent concrete or slug from wrapping around the surface of the frame 24 or the mounting portion 25, and the frame 24 and the mounting portion 25 are reliably displayed when the mold is removed. It can be made to be exposed on the surface of the pile 5.

The concrete 1 poured into the mold 40
After the mold 9 has hardened, the mold 40 of this example is turned upside down, and FIG.
When the display pile 5 is released from the mold as shown in FIG. 6, the projection 30 is cut off, and the display body holder 20 is released from the mold 40 integrally with the display pile 5. Therefore, also in this example, the display pile 5 can be removed from the mold very easily, similarly to the display pile having no buried object.
