Description

  The present invention relates to a foamable heat insulator for a plastic mold used for a plastic mold.

  2. Description of the Related Art Conventionally, a wooden form made of a plywood and a reinforcing frame attached to the outer periphery of the plywood has been used. Since this wooden formwork has low durability, it is disposed of after several uses. Therefore, in recent years, plastic molds advantageous in durability have been proposed.

  By the way, when concrete is placed and hardened using the plastic formwork at a time when the temperature in winter is low, the temperature of the concrete suddenly drops, and cracks and cracks may occur. In order to solve this, in recent years, a form having a heat insulating effect has been proposed. This is comprised from the heat insulation board which consists of a synthetic resin foam, and the reinforcement piercing tree embedded in the ditch | groove formed in one surface of this heat insulation board (for example, refer patent document 1).

Japanese Patent No. 3441434

  Although the formwork of the said patent document 1 can exhibit the heat insulation effect, it is for attaching the hook bolt for hanging a formwork or fixing a formwork to a horizontal pipe, and the clip for connecting formwork There is no mounting hole. Therefore, it is difficult to suspend and fix the formwork or to connect the formwork, and there is room for improvement.

  Therefore, the present invention has been made in view of such circumstances, and is a foam for a plastic mold that can exert a heat insulation effect and can easily perform a hanging work, a fixing work, or a joining work between the molds. It is an object to provide a heat insulating body.

  The foamable heat insulator for a plastic mold according to the present invention is provided along a rectangular flat plate portion having a concrete placement surface and four sides on the back side opposite to the concrete placement surface, and a hook bolt And a plastic mold frame comprising: a peripheral rib in which an attachment hole for attaching at least one of the clips is formed; and a partition rib for partitioning an interior surrounded by the peripheral rib into a plurality of ridges, A foamable heat insulating material for a plastic form housed in a bag, wherein an outer portion located on the peripheral rib side to allow insertion of at least one of the hook bolt and the clip into the mounting hole. It is characterized by being lower than the inner portion that is separated from the peripheral rib.

  According to the present invention, the heat insulating effect can be exerted by housing the foamable heat insulator in the bag. In addition, by setting the outer portion of the foamable heat insulator lower than the inner portion, the hook bolt and the clip can be inserted into the mounting hole without being obstructed by the foamable heat insulator. Therefore, it is possible to smoothly perform the work of suspending and fixing the formwork or the work of connecting the formwork.

  Moreover, the foamable heat insulating body for plastic molds according to the present invention is characterized in that the ridges include a first ridge located at both ends in the width direction of the mold and a second ridge located in the middle in the width direction of the mold. A first foamable heat insulating body and a second foamable heat insulating material, each having a width set to be larger than the width of the second bag and configured to be accommodated in the first bag and the second bag. A width of the first foamable heat insulating body is set to be larger than a width of the second foamable heat insulating body, the first foamable heat insulating bodies are located at both longitudinal ends, and the mounting holes A plate-like both end portions having a lower height, and a substantially triangular main body portion having an inclined surface which is located between the both end portions and becomes higher from the width direction outer end toward the width direction inner end; May be provided.

  As described above, since the width of the first foamable heat insulator is set to be larger than the width of the second foamable heat insulator, the inclined surface becomes higher from the width direction outer end toward the width direction inner end. An angle can be set comparatively moderately and the space which can insert a hook bolt and a clip in a mounting hole reliably can be ensured. Moreover, while providing a heat insulation effect by providing both ends of the flat plate, the thickness of the foam heat insulator increases from the outer side in the width direction toward the inner side in the width direction by the substantially triangular main body, and the heat insulation effect Can be increased.

  Further, the foamable heat insulating body for plastic molds according to the present invention is such that the peripheral rib and the partitioning rib are set at the same height from the flat plate portion, and the peripheral rib in a state where the peripheral rib is accommodated in the bag. And it may be comprised in the height which protrudes from the said rib for a partition.

  According to such a configuration, by setting the inner portion of the foam heat insulator to a height protruding from the peripheral rib and the partition rib, the heat insulation effect can be enhanced, but the foam heat insulator can be taken out from the bag. Easy to work.

  As described above, according to the present invention, the outer portion is made lower than the inner portion so as to allow the hook bolt and the clip to be inserted into the mounting hole. It is possible to provide a foamable heat insulator for a plastic mold that can be easily connected.

And as shown in FIG. 1, many attachment holes H for attaching a hook bolt and a clip are formed in 5 A of upper side ribs, 5 C of left side ribs, and 5 D of right side ribs. Although not shown, a mounting hole is also formed in the lower rib.

  Each of the two foamable heat insulators 1 positioned at both ends in the left-right direction is composed of a first elongated block body configured to be smaller than the first rods 6 and 14 so as to be accommodated in the first rods 6 and 14. Yes. Each of the remaining seven foaming heat insulators 2 is accommodated in the second rods 7, 8, 9, 10, 11, 12, 13 so that the second rods 7, 8, 9, 10, 11, 12, It is comprised from the 2nd elongate block body comprised smaller than 13. FIG. The horizontal width (left-right width) of the first elongate block body 1 is set larger than the horizontal width (left-right width) of the second elongate block body 2. As the foamable heat insulators 1 and 2, polystyrene foam, polyethylene foam, polypropylene foam, rigid urethane foam, phenol foam, isocyanate foam, epoxy foam, and the like can be used. The expansion ratio can be freely changed as appropriate.

  As shown in FIGS. 1, 3 (a), 3 (b), and FIG. 4, the first elongate block body 1 is a flat plate located at both ends in the longitudinal direction and having a height lower than the mounting hole H. 1A and 1A (only one is shown in the figure) and an inclined surface 1S which is located between both end portions 1A and 1A and becomes higher from the width direction outer end toward the width direction inner end. And a main body portion 1B having a substantially triangular shape. At both ends in the longitudinal direction of the main body 1B, inclined surfaces 1R that are higher toward the center in the longitudinal direction are formed. In addition, the inner end surface 1b in the left-right width direction of the main body 1B is recessed so that a gap N1 is formed between the partition ribs 15 and 22, and a finger is put into the gap N1 so that the upper end of the main body 1B 1T can be easily grasped. The flat end portions 1A and 1A and the portion 1B1 lower than the mounting hole H in the main body 1B are defined as outer portions located on the peripheral rib 5 side. Further, a portion 1B2 that is higher than the attachment hole H in the main body 1B is an inner portion that is separated from the peripheral rib 5.

  As shown in FIGS. 1, 2 (a), (b) and FIG. 4, the second elongate block body 2 is a flat plate located at both ends in the longitudinal direction and having a height lower than the mounting hole H.

The second reinforcing ribs 24 positioned second from the right are positioned between the both end portions 24A and 24A and the both end portions 24A and 24A that are positioned at both ends in the left-right direction and rise up to the height of the partitioning ribs 16 and 17. An intermediate portion 24B configured to have a height lower than the height of the partition ribs 16 and 17 (here, a height of half or less) is provided. The other first reinforcing ribs 24 not described have the same configuration.

  In addition, a large number of slits 25 and 26 are formed on the bottom of the first elongate block body 1 and the bottom of the second elongate block body 2 for facilitating bending when accommodated in the elongate troughs 6 to 14. . Each slit 25 or 26 is formed so as to extend in the left-right width direction of the elongated block body 1 or 2, and is formed at a predetermined interval in the longitudinal direction of the elongated block body 1 or 2. Each slit 25 or 26 is formed to correspond to the first reinforcing rib 23 or the second reinforcing rib 24. Each slit 25 or 26 is locked to the first slit 25A or 26A that is locked to the first reinforcing rib 23 or the second reinforcing rib 24, and to the first reinforcing rib 23 or the second reinforcing rib 24. The second slit 25B or 26B is not provided.

  In other words, the longitudinal dimension of the elongated block body of the first slit 25A or 26A is such that the first slit 25A or 26A is locked to the first reinforcing rib 23 or the second reinforcing rib 24. The rib 23 or the second reinforcing rib 24 is configured to have a size slightly larger than the size in the longitudinal direction of the elongated block body. Specifically, as shown in FIGS. 3A and 3B, the first slit 25 </ b> A of one first elongated block body 1 is slightly smaller than the first reinforcing rib 23 having a rectangular cross section. The first slit 25A enters the first reinforcing rib 23 and is locked therewith. Further, the second slit 25B of the first elongated block body 1 is formed in a slit in which a trapezoidal space far larger than the rectangular first reinforcing rib 23 having a vertically long cross section is formed, and the second slit 25B. However, it only covers the first reinforcing rib 23 and does not engage with the first reinforcing rib 23. Further, the first slit 26A of the other second elongated block body 2 is formed in a slit in which a trapezoidal space slightly larger than the rectangular second reinforcing rib 24 having a vertically long cross section is formed. The slit 25 </ b> A enters the second reinforcing rib 24, and the narrow space at the upper end of the first slit 25 </ b> A is locked to the upper end of the second reinforcing rib 24. In addition, the second slit 26B of the second elongated block body 2 has a rectangular section 26b having a large dimension in the longitudinal direction and a rectangular section 26b that is horizontally long (long in the longitudinal direction of the heat insulating body 2) and the upper ends of the corner sections 26b. And a trapezoidal trapezoidal portion 26c extending upward from the second reinforcing rib 24. The second reinforcing rib is formed simply by covering the second reinforcing rib 24 with the second slit 26B. Do not lock to 24. These first slits 25A or 26A and second slits 25B or 26B are alternately provided in the longitudinal direction of the first elongated block body 1 or the second elongated block body 2.

  Therefore, the 1st elongate block body 1 (or 2nd elongate block body 2) is provided with the slit 25 (or slit 26), and the 1st elongate block body 1 or the 2nd elongate block body 2 is made into the eaves 6-14. The first elongate block body 1 (or the second elongate block body 2) can be bent at the slit 25 (or the slit 26) when being accommodated. 2B shows a state where the second elongate block body 2 is bent by the slit 26 by a two-dot chain line in FIG. Therefore, the first elongate block body 1 or the second elongate block body 2 is hardly cracked or cracked and can be satisfactorily accommodated in the ridges 6 to 14.

  When the first elongate block body 1 or the second elongate block body 2 is accommodated in the flanges 6 to 14, the first slit 25A or 26A is locked to the first reinforcing rib 23 or the second reinforcing rib 24. Thus, the elongated first elongated block body 1 or the second elongated block body 2 can be securely held by the mold 3. Further, when the first elongate block body 1 or the second elongate block body 2 is accommodated in the flanges 6 to 14, the second slit 25 </ b> B or 26 </ b> B is engaged with the first reinforcement rib 23 or the second reinforcement rib 24. Therefore, the first elongate block body 1 or the second elongate block body 2 can be smoothly accommodated in the ridges 6-14. Further, the first slits 25A or 26A and the second slits 25B or 26B are alternately provided in the longitudinal direction of the first elongated block body 1 or the second elongated block body 2, whereby the first slits 25A or 26A and the first slits 25A or 26A are provided. The first elongate block body 1 or the second elongate block body 1 or the second elongate block body 2 is securely held by the mold 3 by the engagement with the reinforcing rib 23 or the second reinforcing rib 24. The elongated block body 2 can be smoothly accommodated in the ridges 6-14.

Although not shown, a mounting hole is also formed in the lower rib.

  Each of the two foamable heat insulators 27 located at both ends in the left-right direction is composed of a first elongated block body having a lateral width (left-right width) accommodated in the first rods 32 and 38. Each of the remaining five foamable heat insulators 28 is composed of a second elongated block body having the same lateral width (left-right width) accommodated in the second rod 33, 34, 35, 36, 37. The lateral width (left-right width) of the first elongated block body 27 is set to be larger than the lateral width (left-right width) of the second elongated block body 28. As the foam heat insulators 27 and 28, polystyrene foam, polyethylene foam, polypropylene foam, hard urethane foam, phenol foam, isocyanate foam, epoxy foam, or the like can be used. The expansion ratio can be freely changed as appropriate.

And a main body portion 27B having a substantially triangular shape. Inclined surfaces 27R are formed at both ends in the longitudinal direction of the main body 27B so as to increase toward the center in the longitudinal direction. In addition, the inner end surface 27b in the left-right width direction of the main body 27B is inclined so that a gap N2 is formed between the ribs 39 or 44 for partitioning, and a finger is put into the gap N2 so that the upper end of the main body 27B The part can be easily grasped. The flat end portions 27A and 27A and the portion 27B1 lower than the mounting hole H in the main body portion 27B are outer portions located on the peripheral rib 31 side.

In addition, the second slit 48B of the first elongated block body 27 has a rectangular section 48b having a large dimension in the longitudinal direction and a rectangular section 48b that is horizontally long (long in the longitudinal direction of the heat insulator 27) and the upper end of the square section 48b. The trapezoidal trapezoidal portion 48c extending upward from the second slit 48B only covers the first reinforcing rib 45 and does not engage with the first reinforcing rib 45. The first slit 49A of the other second elongated block body 28 is formed in a slit in which a trapezoidal space slightly larger than the rectangular second reinforcing rib 46 whose section is vertically long is formed, and the first slit 49A. Enters the second reinforcing rib 46 and the narrow space at the upper end of the first slit 49 </ b> A is locked to the upper end of the second reinforcing rib 46. In addition, the second slits 49B of the second elongate block body 28 are rectangular rectangular portions 49b having a large cross-section in the longitudinal direction and having a horizontally long cross section (long in the longitudinal direction of the heat insulator 28) and the upper ends of the square portions 49b. And a trapezoidal trapezoidal portion 49c extending upward from the second reinforcing rib 46. The second reinforcing rib simply covers the second reinforcing rib 46 by the second slit 49B. 46 is not locked. The first slits 48A or 49A and the second slits 48B or 49B are alternately provided in the longitudinal direction of the first elongated block body 27 or the second elongated block body 28. In FIG. 6, the square part 49b of the ninth second slit 49B from the right is larger in the longitudinal direction than the square part 49b of the other second slit 49B.

  Therefore, the first elongate block body 27 (or the second elongate block body 28) includes the slit 48 (or the slit 49), so that the first elongate block body 27 or the second elongate block body 28 is turned into the flanges 32 to 38. When accommodated, the first elongate block body 27 (or the second elongate block body 28) can be bent at the slit 48 (or the slit 49) (similar to FIG. 2B). Not shown). Therefore, the first elongate block body 27 or the second elongate block body 28 is hardly cracked or cracked and can be satisfactorily accommodated in the ridges 39 to 44.

  Further, when the first elongate block body 27 or the second elongate block body 28 is accommodated in the flanges 39 to 44, the first slit 48A or 49A is locked to the first reinforcing rib 45 or the second reinforcing rib 46. Thus, the elongated first block body 27 or the second elongated block body 28 can be securely held by the mold 29. Further, when the first elongate block body 27 or the second elongate block body 28 is accommodated in the flanges 39 to 44, the second slits 48B or 49B are engaged with the first reinforcing rib 45 or the second reinforcing rib 46. Therefore, the first elongate block body 27 or the second elongate block body 28 can be smoothly accommodated in the ridges 39 to 44. Furthermore, the first slit 48A or 49A and the second slit 48B or 49B are alternately provided in the longitudinal direction of the first elongated block body 27 or the second elongated block body 28, whereby the first slit 48A or 49A and the first slit 48A or 49A and the first slit 48A or 49A are provided. The first elongate block body 27 or the second elongate block body 27 or the second elongate block body 27 can be securely held on the mold 29 by the engagement with the reinforcing rib 45 or the second reinforcing rib 46. The elongated block body 28 can be smoothly accommodated in the flanges 39 to 44.

  In addition, a concave groove 28M continuous in the longitudinal direction is formed in the left and right central portion of the bottom of the second elongated block body 28, so that the weight of the second elongated block body 28 can be reduced. Further, by forming a concave groove 28M in the bottom of the second elongated block body 28, ribs 50 and 51 are formed on the upper surface of the flat plate portion 30 so as to protrude along the longitudinal direction of the heat insulator (see FIGS. 5 and 8). ) In the concave groove 28M, it is possible to avoid the bottom of the second elongated block body 28 from coming into contact with the ribs 50 and 51.

  The present invention is not limited to the two embodiments described above, and various modifications can be made without departing from the scope of the present invention.

  In the second embodiment, the concave groove 28M is formed at the bottom of the second elongated block body 28, but the concave groove may be omitted and the bottom of the second elongated block body 28 may be formed flat.

  Moreover, in the said 1st and 2nd embodiment, although the cross section comprised the 1st elongate block bodies 1 and 27 in the triangle shape, you may comprise in any shapes, such as trapezoid shape and step shape. That is, the shape of the first elongate block body can be freely changed as long as the hook bolt and the clip can be inserted into the mounting hole H.

  In addition, the number and size of the foam heat insulators shown in the first and second embodiments can be changed according to the formwork.
