JP 7-290431 A

  However, in the above conventional panel molding apparatus disclosed in Patent Document 1, the concrete mold is laid and the panel molding is performed by so-called flat laying, and the area occupied by the mold increases on the floor. The number of panels is limited. Moreover, in the conventional panel molding apparatus which press-molds a concrete panel, special special equipment is required and it cannot perform panel molding easily.

  An object of the present invention is to provide a panel molding apparatus with improved productivity that can mold a large number of panels at a time without using special dedicated equipment.

For this reason, the present invention

Panel holding means for holding the panel in a standing state by supporting the both side ends of the panel whose front plate and back plate are moved from the front and back by the moving means with a pair of side plates;
Panel fall prevention means for temporarily preventing the fall of the panel released from being held by the panel holding means;
The panel molding apparatus is configured to include a demolding unit that lifts or lifts the panel that is released from being held by the panel holding unit and has been prevented from falling by the panel overturn preventing unit, and demolds the panel.

  According to this configuration, the mold is erected to form a space surrounding the four sides with the front plate, the back plate, and the pair of side plates. The panel is shaped by pouring a panel forming material into this space formed corresponding to its outer shape. The shaped panel is released by moving the front plate and the back plate covering the front and back surfaces of the panel in a direction away from each other. Furthermore, the both sides of the panel from which the front plate and the back plate are moved from the front and back are supported by the pair of side plates by the panel holding means, so that the panel is held in a standing state. Thereafter, the holding of the panel by the panel holding means is released. The panel released from the holding by the panel holding means is temporarily prevented from falling by the panel falling prevention means and is lifted or lifted by the releasing means to be removed from the mold.

  Therefore, the panel forming apparatus of this configuration for forming the panel by pouring the panel forming material into the mold in this way can be configured without using special dedicated equipment, unlike the conventional panel forming apparatus for press forming. In addition, since the formwork that models the panel is erected, the floor area required for installation of the formwork does not require a large area, unlike the conventional panel forming apparatus that flat-molds the panel. Therefore, by providing a plurality of standing molds, it is possible to provide a panel molding apparatus with improved productivity that can mold a large number of panels at a time without using special dedicated equipment.

  Further, according to the present invention, the panel holding means supports the pair of side plates, which are moved away from each other in the direction in which the front plate and the back plate are separated from each other, using members from both sides. The panel is held in a standing state by being kept standing.

  According to this structure, the front plate and the back plate are moved away from each other by the moving means, and the pair of side plates that are not engaged with the front plate and the back plate are separated from each other by the panel holding means. The panel is held in a standing position by using and to keep it standing.

  Further, according to the present invention, the panel overturn prevention means is provided by hanging a hanging tool provided on the panel, holding the panel, pressing the upper end of the panel downward, or Locking the upper end temporarily prevents the panel from overturning.

  According to this configuration, the temporary overturn prevention of the panel by the panel overturn prevention means can be achieved by hanging a suspension provided on the panel, holding the panel, or pressing the upper end of the panel downward. Or by locking the upper end of the panel.

  Further, according to the present invention, the mold releasing means lifts the suspension provided on the panel, or lifts the panel by gripping, or both sides of the panel exposed by releasing the holding by the panel holding means. It is characterized in that the panel is removed by lifting while pinching the end.

  According to this configuration, the removal of the panel from the formwork by the removal means is performed by lifting a suspension provided on the panel, holding the panel to lift the panel, or holding by the panel holding means. This is done by sandwiching and lifting the both ends of the exposed panel.

The present invention also provides:
The side plate is supported by the upper end side so as to be rotatable about the rotation fulcrum on the lower end side, or is attached to the mold form so as to be removable from the mold form,
The panel holding means releases the holding of the panel when the upper end side of the side plate rotates around the pivot point and moves away from the side edge of the panel, or when the side plate is removed from the formwork. Features.

  According to this configuration, when the upper end side of the side plate is supported so as to be pivotable about the pivot point on the lower end side, the upper end side of the side plate pivots about the pivot point and moves away from the side edge of the panel. Thus, the holding of the panel by the panel holding means is released. When the side plate is detachably attached to the formwork, the side plate is removed from the formwork, so that the holding of the panel by the panel holding means is released.

The present invention also provides:
The side plate is provided with a predetermined length portion on the upper end side so as to be rotatable in a direction away from the panel, or detachably provided from the remaining portion,
The panel overturn prevention means temporarily prevents the panel from overturning by sandwiching both side ends of the panel exposed by turning or removing a predetermined length portion on the upper end side of the side plate,
The demolding means demolds the panel by sandwiching and lifting the both side ends of the exposed panel.

  According to this configuration, when the predetermined length portion on the upper end side of the side plate is provided so as to be rotatable in the direction away from the panel, the panel released from the holding by the panel holding means is the predetermined length portion on the upper end side of the side plate. The both ends of the panel exposed by turning are sandwiched by the panel fall prevention means, so that the fall is temporarily prevented. Further, when the predetermined length portion on the upper end side of the side plate is provided to be removable from the remaining portion, the panel released from the holding by the panel holding means is the panel exposed by removing the predetermined length portion on the upper end side of the side plate. By sandwiching the both ends of the panel by the panel fall prevention means, the fall is temporarily prevented. In either case, the both ends of the exposed panel are sandwiched and lifted by the demolding means to be demolded.

The present invention also provides:
The side plate has a predetermined length portion on the upper end when the predetermined length portion on the upper end side is vertically divided and divided into two on both the front plate and the rear plate, and the space is formed by the front plate and the rear plate. Is combined with the rest to form an integral shape,
The panel fall prevention means holds the both side edges of the exposed panel by being moved by the moving means in a direction in which the front plate and the back plate are separated from each other and the predetermined length portion on the upper end side of the side plate is divided into two. In order to temporarily prevent the panel from falling,
The demolding means demolds the panel by sandwiching and lifting the both side ends of the exposed panel.

  According to this configuration, the panels released from being held by the panel holding means are moved by moving the front plate and the back plate so that the predetermined length portion on the upper end side of the side plate is divided into two, and the both side ends of the panel exposed. However, by being sandwiched by the panel fall prevention means, the fall is temporarily prevented. Then, the both side ends of the exposed panel are sandwiched and lifted by the demolding means to be demolded.

  In addition, the present invention provides a predetermined contact relative to the panel in order to temporarily prevent the panel from overturning by the panel overturn prevention means or to remove the panel by the demolding means. Guide means for guiding the position is provided.

  According to the present configuration, the temporary fall prevention of the panel by the panel fall prevention means and the demolding of the panel by the demolding means are performed by some kind of contact with the panel. At this time, the contact is It is guided to a predetermined relative position with respect to the panel by the guide means and comes into contact with the panel. For this reason, the contactor comes into reliable and quick contact with the panel at a position necessary for preventing the panel from falling over or removing the panel. The panel can be removed from the mold reliably and quickly.

The present invention also provides:
A shaft protruding from the side of the back plate facing the space, a metal insert embedded in the panel by magnetic force, a magnet inserted into the shaft and attached to the side of the back plate, and a predetermined metal insert A fitting part that exists at the end of the shaft and that has an outer diameter that fits with play, and the panel forming material poured into the formwork enters the metal insert from the abutment part between the magnet and the metal insert. And a packing material for preventing intrusion, and a depression for accommodating the packing material is formed around the contact surface between the magnet and the metal insert.

  According to this configuration, each panel is formed by pouring the panel forming material into a space formed by being sandwiched between the back plate and the front plate, and a metal insert protrudes into this space. Therefore, a metal insert is embedded in the back surface of the panel that is formed by pouring the panel forming material into this space, and the metal insert is integrated with the panel. At this time, the metal insert is attracted by a magnetic force to a magnet mounted on the side surface of the back plate by being fitted to a fitting portion present at the end of the shaft protruding from the side surface of the back plate. Even if the forming material is poured into the space and a force is applied to the metal insert, the installation position does not change. For this reason, the metal insert is accurately embedded at a predetermined position on the back surface of the panel.

  In addition, the packing material prevents the panel forming material poured into the mold from entering the inside of the metal insert from the contact portion between the magnet and the metal insert. The panel forming material is not clogged in the groove of the female thread. Further, the packing material is accommodated in the depression, and the packing material is held around the contact surface between the magnet and the metal insert even when the panel forming material is poured into the mold. This reliably prevents the panel forming material from entering the inside of the metal insert from the contact portion between the magnet and the metal insert.

  After the panels are shaped, the front plate covering the front of each panel and the back plate covering the back of each panel are moved away from each other by the moving means, and the panels are released. At this time, since the metal inserts embedded in the back of each panel are merely attracted to the magnet by being fitted to the fitting portion with a predetermined play, the force for pulling the back plate away from the panel is this suction. Overcoming the force, the metal insert is easily removed from the fitting against the suction force. For this reason, metal inserts can be embedded in the back of each panel easily, accurately and efficiently.

The present invention also provides:
A pedestal formed with a storage chamber for storing a magnet, which is inserted into the shaft and attached to the side surface of the back plate in contact with the bottom surface, is provided on the side surface of the back plate,
The magnet is housed in the housing chamber and attached to the side surface of the back plate.

  According to this configuration, since the magnet is stored in the storage chamber of the pedestal and attached to the side surface of the back plate, the magnet can be easily attached to and detached from the side surface of the back plate together with the pedestal. Further, when the pedestal is made of metal, the magnetic force of the magnet is increased, so that the magnet can be miniaturized.

The present invention also provides:
A recess for housing the magnet is formed on the side surface of the back plate,
The magnet is housed in the recess and attached to the side surface of the back plate.

  According to this configuration, the magnet is housed in the recess formed on the side surface of the back plate and attached to the side surface of the back plate, so that the embedded position of the metal insert in the panel depends on the depth of the recess, The exposed end surface of the metal insert is positioned so as to be flush with or close to the back surface of the panel.

  Further, the present invention is characterized in that the magnet is covered with a cap.

  According to this configuration, since the magnet is protected by the cap, it is difficult to chip. In addition, even if it is missing, it can be easily repaired by simply replacing the magnet together with the cap without causing the troublesome work of the missing magnet to adhere to the side surface of the back plate or the base and peel it off. be able to. Moreover, since the magnetic force of a magnet increases when a cap is metal, a magnet can be reduced in size.

The present invention also provides:
A shaft protruding from the side surface of the back plate on the side facing the space, and a press-fitting portion present at the end of the shaft having an outer diameter press-fitted into a nonmagnetic insert embedded in the panel.

  According to this configuration, when the panel forming material is poured into the formwork and the nonmagnetic insert is embedded in the back surface of the panel, the nonmagnetic insert is a press-fit portion that is present at the end of the shaft protruding from the side surface of the back plate. Therefore, even if a force is applied to the nonmagnetic insert from the poured panel forming material, the installation position does not change. For this reason, the nonmagnetic insert is accurately embedded at a predetermined position on the back surface of the panel. Also, when the panel is released, the non-magnetic insert embedded in the back of the panel is only press-fitted into the press-fitting part, so the force to pull the back plate away from the panel is superior to this press input, and the non-magnetic insert Is easily removed from the press-fit portion against the pressure input. For this reason, the nonmagnetic insert can be embedded in the back surface of each panel easily, accurately and efficiently.

    Further, the present invention is characterized in that a protrusion is formed on a side surface facing the space of each of the pair of side plates.

  When the front plate and the back plate that cover the front and back of the panel are moved away from each other by the moving means, they adhere to each other between the front and front plates of the panel and between the back and back plates of the panel. Adhesive force is created and the panel is pulled in both directions away. For this reason, the action of the panel holding means that tries to hold the panel in a standing state by supporting both sides of the panel with a pair of side plates becomes unstable due to this pulling force. It can be shifted to either one. However, according to this configuration, since the protrusion is formed on the side surface of each of the pair of side plates facing the space that shapes the panel, the panel is pulled in both directions that separate when the panel is released by the moving means. However, the both sides of the panel are supported by the protrusions formed on the side plates so that they do not shift. Therefore, the mutual positions of the both side ends of the panel and the pair of side plates are firmly fixed, and are securely held by the panel holding means without fear of detaching the panel.

  According to the present invention, as described above, it is possible to provide a panel molding apparatus with improved productivity capable of molding a large number of panels at a time without using special dedicated equipment.

  The concrete panel 5 removed from the mold and lifted up is collected from the state shown in FIG. 28 (a) and then as shown in FIG. 28 (b), as in the fourth embodiment. Then, they are packed and shipped as shown in FIG.

  Such a sixth embodiment also provides a panel forming apparatus 1E with improved productivity that can form a large number of concrete panels 5 at a time without using special dedicated equipment. The same effects as the panel molding apparatus 1C according to the embodiment are exhibited.

  In each of the above embodiments and modifications, as shown in FIG. 6, the magnets 10 are accommodated in the pedestals 9, 9 provided on both side surfaces of the back plate 3, and the back of the concrete panel 5 is accommodated. The configuration in which the metal inserts 7 and 7 to be embedded are fitted to the fitting portion 8a and the fitting portion 11 while being attracted by the magnets 10 and 10 has been described. However, as a first modification of the structure for mounting the embedded insert to the back plate 3, the magnets 10 and 10 are mounted in a state where they are exposed on both sides of the back plate 3 without being housed in the bases 9 and 9. It is good also as a structure to be. In this configuration, the metal inserts 7 and 7 are fitted to the fitting portion 8 a and the fitting portion 11 while being attracted by the magnets 10 and 10 that are present alone on both side surfaces of the back plate 3. Further, as shown in FIG. 42 (a), the recesses 3c and 3c for storing the magnets 10 and 10 are formed on both side surfaces of the back plate 3, and the magnets 10 and 10 are stored in the recesses 3c and 3c and It is good also as a structure with which 3 side surfaces are mounted | worn. FIG. 42A is an exploded view showing a second modification of the structure for mounting the embedded insert to the back plate 3.

  Further, in each of the above-described embodiments and modifications, the configuration in which the shaft 8 is integrally formed with the fitting portion 8a at the head has been described. However, the shaft 8A shown in the figure, which is not formed integrally with the head like the shaft 8 described above and is formed in a cut shape, may be used. In this case, the fitting parts 11, 11, which are separate parts, are screwed into both ends of the shaft 8 </ b> A, so that the fitting parts 11, 11 exist at both ends of the shaft 8 </ b> A as shown in FIG. Like that. In FIG. 6B, the shaft 8A is passed through the back plate 3, magnets 10 are inserted into the shaft 8A protruding from both side surfaces of the back plate 3, and the fitting portions 11 are inserted at both ends of the shaft 8A. , 11 are screwed together. FIG. 3C is a side view of the state in which the metal inserts 7 and 7 are further attached to the fitting portions 11 and 11 protruding on both side surfaces of the back plate 3.

  According to this configuration, the magnets 10 and 10 are housed in the recesses 3c and 3c formed on both side surfaces of the back plate 3 and attached to both side surfaces of the back plate 3, so that the metal insert 7 in the concrete panel 5 is provided. , 7 is located at a position where the exposed end surfaces of the metal inserts 7, 7 are flush with or close to the back surface of the concrete panel 5, depending on the depth of the recesses 3c, 3c. In each of the above-described embodiments and modifications, the magnets 10, 10 are accommodated in the pedestals 9, 9, or the single magnets 10, 10 project from both side surfaces of the back plate 3, so that the concrete panel The embedded positions of the metal inserts 7 and 7 in FIG. 5 are positions where the exposed end surfaces of the metal inserts 7 and 7 are lowered from the back of the panel according to the height of the bases 9 and 9 or the height of the magnets 10 and 10. .

  Further, the magnet 10 is configured such that the periphery thereof is covered with a cap 12 as in the third modification of the structure for mounting the embedded insert to the back plate 3 shown in FIGS. 43 (a) and 43 (b). May be. Parts (a) and (b) of FIG. 42 that are the same as or equivalent to those of FIGS. 42 (b) and (c) are assigned the same reference numerals, and descriptions thereof are omitted. Further, the magnet 10 that is accommodated in the pedestal 9 in each of the above-described embodiments and modifications, or that is exposed to both side surfaces of the back plate 3 without being accommodated in the pedestal 9 is covered with the cap 12. You may comprise. In this case, a front view and a sectional view of the magnet 10 are shown in FIG. 43C, and a front view and a sectional view of the cap 12 are shown in FIG. A front view and a cross-sectional view of the state where the magnet 10 is covered with the cap 12 are shown in FIG.

  According to this structure, since the magnet 10 is protected by the cap 12, it becomes difficult to chip. Also, even if the magnet 10 is missing, the magnet 10 and the cap 12 together with the cap 12 do not incur the troublesome work of attaching the chipped magnet 10 to the side surface of the back plate 3, the recess 3 c, the pedestal 9, etc. Repair can be easily performed by simply replacing 10. Moreover, since the magnetic force of a magnet increases when the cap 12 is metal, the magnet 10 can be reduced in size.

  Further, in each of the above embodiments and modifications, as shown in FIG. 44 (a), a packing material such as grease is provided around the contact portion between the magnet 10 housed in the base 9 and the metal insert 7. 13 may be provided. At this time, even if the periphery of the magnet 10 is covered with the cap 12, similarly, the packing material 13 can be provided around the contact portion between the magnet 10 and the metal insert 7.

  In the third modification of the embedded insert mounting structure shown in FIG. 43, as shown in FIG. 44 (b), the magnet 10 covered with the cap 12 housed in the recess 3c, and the metal insert 7 The packing material 13 may be provided around the contact portion. At this time, in the second modification of the embedded insert mounting structure shown in FIG. 42 in which the periphery of the magnet 10 is not covered with the cap 12, the magnet 10 is further provided on both side surfaces of the back plate 3. Similarly, in the first modified example of the mounting structure for the embedded insert, the packing material 13 can be provided around the contact portion between the magnet 10 and the metal insert 7.

  44 (a) and 44 (b), the packing material 13 exists over a range W that covers the periphery of the contact surface between the magnet 10 and the metal insert 7. Therefore, according to these configurations, the packing material 13 prevents the concrete poured into the mold from entering the inside of the metal insert 7 from the contact portion between the magnet 10 and the metal insert 7. For this reason, the concrete is not clogged in the groove of the female screw formed inside the metal insert 7.

  Further, in the configuration shown in FIG. 44 (a), a depression 14a for accommodating the packing material 13 is formed around the contact surface between the magnet 10 and the metal insert 7, and in the configuration shown in FIG. 44 (b), a depression 14b is formed. You may make it do. The depression 14a is such that the opening end of the storage chamber 9a that accommodates the magnet 10 of the base 9 spreads in two steps, and the height of the contact surface between the magnet 10 and the metal insert 7 is lowered from the height of the base 9. The depression 14b is formed such that the inner peripheral edge of the cap 12 is tapered, and the height of the contact surface between the magnet 10 and the metal insert 7 is lowered from the side surface of the back plate 3. ,It is formed. According to these structures, the packing material 13 is accommodated in the depressions 14a and 14b, and the packing material 13 is held around the contact surface between the magnet 10 and the metal insert 7 even when concrete is poured into the mold. The For this reason, the concrete is reliably prevented from entering the inside of the metal insert 7 from the contact portion between the magnet 10 and the metal insert 7.

  In the structure in which the magnet 10 shown in FIG. 44B is housed in the recess 3c, the magnet 10 is covered with the cap 12, but the magnet 10 is not covered with the cap 12. The second modification shown in FIG. Even in this structure, the height of the contact surface between the magnet 10 and the metal insert 7 is made lower than the side surface of the back plate 3, and the back plate 3 surrounding the periphery of the magnet 10 is formed into a tapered shape, for example, to form a depression. As a result, similarly, the concrete is reliably prevented from entering the inside of the metal insert 7 from the contact portion between the magnet 10 and the metal insert 7. Further, also in the first modification of the embedded insert mounting structure in which the magnet 10 is provided exposed on both side surfaces of the back plate 3, a recess is provided on the exposed end surface of the magnet 10, and the magnet 10 and the metal insert in the recess are provided. The height of the abutting surface with 7 is lower than the height of the exposed end surface of the magnet, and the magnet 10 surrounding the abutting surface is formed into a tapered shape, for example, to form a depression. In addition, the concrete is reliably prevented from entering the inside of the metal insert 7 from the contact portion between the magnet 10 and the metal insert 7.

  Further, in each of the above-described embodiments and modifications, the metal insert 7 is attached to the back plate 3 by fitting the metal insert 7 into the fitting portions 8 a and 11 while attracting the metal insert 7 with the magnet 10. The configuration has been described. However, as shown in FIG. 45, the resin insert 15 may be mounted on the back plate 3 by press-fitting the nonmagnetic resin insert 15 into the press-fit portions 8Ba and 16. FIG. 6A is an exploded view showing a fourth modification of the structure for mounting the embedded insert to the back plate 3 constituted by using the resin insert 15. The shaft 8B is formed by integrally forming a press-fit portion 8Ba on the head of the bolt, and is penetrated through the back plate 3 as shown in a side view of FIG. Then, the press-fit portion 16 is screwed into the end portion of the shaft 8B protruding to one side of the back plate 3, and the press-fit portions 8Ba and 16 are present at both end portions of the shaft 8B on both sides of the back plate 3. Resin inserts 15 and 15 embedded in the concrete panel 5 are press-fitted and attached to the press-fitting portions 8Ba and 16 protruding on both sides of the back plate 3 as shown in the side view of FIG.

  46A shows a shaft 8B, FIG. 46B shows a press-fitting portion 16, and FIG. 46C shows a front view and a side view of the resin insert 15, respectively. The internal hole of the resin insert 15 is formed with a female screw, but there is no female screw forming portion at the opening side end portion, and the side surface of the press-fit portions 8Ba and 16 is smooth so as to be press-fitted. . The side portions of the press-fit portions 8Ba and 16 have an outer diameter that is press-fit into the smooth surface forming portion of the resin insert 15.

  According to this configuration, when the concrete is poured into the formwork and the resin insert 15 is embedded in the back surface of the concrete panel 5, the resin insert 15 exists at both ends of the shaft 8 </ b> B that penetrates the back plate 3. Since it is press-fitted into the press-fitting parts 8Ba and 16, even if a force is applied to the resin insert 15 from the poured concrete, the installation position does not change. For this reason, the resin insert 15 is accurately embedded at a predetermined position on the back surface of the concrete panel 5. Further, when the concrete panel 5 is released, the resin insert 15 embedded and fixed on the back surface of the concrete panel 5 is only press-fitted into the press-fit portions 8Ba and 16, so that the back plate 3 is attached to the concrete panel. The force pulled away from 5 is superior to this pressure input, and the resin insert 15 is easily removed from the press-fit portions 8Ba and 16 against the pressure input. For this reason, while the back plate 3 is shared between adjacent molds, the floor area occupied by each standing mold is reduced, and the panel molding apparatuses 1, 1A to 1E are further miniaturized. The resin insert 15 can be embedded in the back surface of each concrete panel 5 easily, accurately and efficiently.

  In each of the above-described embodiments and modifications, the shafts 8, 8 </ b> A, 8 </ b> B penetrate the back plate 3, and both ends of the shafts 8, 8 </ b> A, 8 </ b> B project to both sides of the back plate 3. ,explained. However, the shafts 8, 8 </ b> A, 8 </ b> B do not necessarily have to penetrate the back plate 3. When the back plate 3 is relatively thin, the number of parts can be reduced by adopting a configuration in which the shafts 8, 8A, 8B penetrate the back plate 3 as described above. However, when the back plate 3 is thick, it is difficult to make such a configuration. For example, a female screw hole is formed on each side surface of the back plate 3 and each end portion of the two shafts on which the male screw is formed is provided. It can also be set as the structure which a shaft protrudes in the both sides of the backplate 3 also by screwing in this female screw hole. Also in this case, the fitting portions 8a and 11 and the press-fit portions 8Ba and 16 are made to exist integrally with the shaft or separately from the other end portion of each shaft protruding on both sides of the back plate 3.

  Moreover, in each said embodiment and each modification, the back plate 3 was shared between the adjacent formwork, and demonstrated the structure which partitions off the concrete poured into each adjacent formwork. However, the back plate 3 is not necessarily shared between adjacent molds, and may be provided for each mold that forms the concrete panel 5. In this case, each formwork may be arranged so that the concrete panels 5 face in opposite directions as in each of the above embodiments and modifications. Also, each of the above embodiments and modifications. Unlike the above, the concrete panels 5 can be arranged in the same direction.

  In each of the above-described embodiments and modifications, the panel holding means moves in a direction in which the front plate 2 and the back plate 3 are separated from each other, and the protrusions 2b and 3b are fitted to the grooves 4a and 4a. By maintaining the pair of side plates 4, 4 that have been released from the engagement with the front plate 2 and the back plate 3 in a state of being supported and supported by the pipes 29, 29 from both sides, the concrete panel 5 The case where the device is kept standing has been described. However, the projections 2b and 3b and the grooves 4a and 4a are provided, and pins that penetrate the front plate 2, the back plate 3, and the side plate 4 are separately provided. This pin constitutes the engaging means for engaging the front plate 2, the back plate 3 and the side plate 4 together with the projections 2b and 3b and the grooves 4a and 4 when the mold is tightened. When the match is lost, a panel holding means for holding the concrete panel 5 in the standing state may be configured by maintaining the pair of side plates 4 and 4 in a standing state by pins. In this case, the holding of the concrete panel 5 by the panel holding means is released by removing the pins penetrating the front plate 2, the back plate 3 and the side plate 4.

  Further, in each of the above-described embodiments and modifications, as shown in FIG. 47, the side surfaces of the pair of side plates 4, 4 facing the space where the concrete panel 5 is shaped and the top surface of the bottom plate 6 are prevented from slipping. You may comprise so that protrusion may be formed with the pin 64. FIG. FIG. 4A is a plan view of the main part of the panel forming apparatus 1 in a state in which the side plates 4 and 4 according to this modification are opened, and FIG. FIG. 4C is a front view of the main part of the panel forming apparatus 1 before and after being supported by the side plates 4, 4.

  The concrete panel 5 is held in a standing state by the pair of side plates 4 and 4 constituting the panel holding means being in a closed state indicated by dotted lines in FIG. Yes. At the time of releasing the panel, in this state, the front plate 2 and the back plate 3 that cover the front and back surfaces of the concrete panel 5 are moved away from each other by the moving means. At this time, an adhesive force is generated between the front surface of the concrete panel 5 and the front plate 2 and between the back surface and the back plate 3 of the concrete panel 5, and the concrete panel 5 is pulled in both directions away from each other. . For this reason, the action of the panel holding means that supports the both ends of the concrete panel 5 with the pair of side plates 4 and 4 to hold the concrete panel 5 in an upright state becomes unstable due to this pulling force, The panel 5 may be shifted to either the front side or the back side.

  However, according to this configuration, since the protrusions are formed by the displacement preventing pins 64 on the side surfaces of the pair of side plates 4 and 4 and the upper surface of the bottom plate 6, the concrete panel 5 is released when the concrete panel 5 is released by the moving means. Even if the concrete panel 5 is pulled in two directions away from each other, the both ends and the bottom surface of the concrete panel 5 are supported by the protrusions formed on the side plates 4 and 4 and the bottom plate 6 so that they do not shift. Therefore, when the panel is released, the mutual positions of both side edges and bottom surface of the concrete panel 5 and the pair of side plates 4, 4 and the bottom plate 6 are firmly fixed, and the concrete panel 5 is securely held by the panel holding means without fear of coming off. Is done. The effect is that the both side ends of the concrete panel 5 with which the side plates 4 and 4 abut are not formed into a concavo-convex shape having a step as shown in FIG. 3, but a flat shape as shown in FIG. This is particularly noticeable when the side plates 4 and 4 are slippery. After the front plate 2 and the back plate 3 are moved from the front and back of the concrete panel 5 as described above, the pair of side plates 4 and 4 are shown by solid lines from the closed state shown by dotted lines in FIG. The concrete panel 5 is removed from the mold by being turned to the open state.

  Here, the protrusions are formed by the detent pins 64 on the side surfaces of the side plates 4 and 4 and the upper surface of the bottom plate 6, but it is sufficient that the projections are formed on at least the side surfaces of the side plates 4 and 4. It is not always necessary to form the upper surface of 6. When the concrete panel 5 is supported by a side plate 4A provided with a predetermined length portion 4A1 on the upper end side so as to be rotatable about the shaft 4A2, as shown in FIG. 32 (b), the side plate 4A. By similarly forming protrusions on the side surface of the remaining portion 4A3, the panel holding means securely holds the panel without releasing the possibility of detaching the concrete panel 5 when the panel is released. Further, as shown in FIG. 38, when the concrete panel 5 is supported by the side plate 4B divided into the front side portion 4B1 and the back side portion 4B2, it is formed on the side surface of the remaining portion 4B3 of the side plate 4B. Similarly, by forming the protrusion, the panel holding means can securely hold the panel without releasing the possibility of the concrete panel 5 coming off when the panel is released.
