Description

  The present invention relates to a plate material made of foamed resin, that is, a plate material used as a formwork or a partition wall.

A conventional partition wall is constructed by placing a base pillar between a ceiling-side runner with a U-shaped cross section installed on the ceiling side and a floor-side runner with a U-shaped cross section installed on the floor side. The wall material was pasted. However, when the partition wall has a curved surface, that is, when the entire partition wall is formed in a curved shape, a curved surface cannot be formed with a wall material such as a gypsum board. Therefore, the plywood is bent in a curved shape. On the other hand, the plywood is also used as the dam plate in the mold, but in the case of the mold having a curved surface, the plywood is bent and formed. Moreover, as another partition wall, there exists invention of Unexamined-Japanese-Patent No. 2005-9263.
JP 2005-9263 A

  However, the above partition walls and formwork use plywood as wall material and dam plate, and when it forms a curved surface, it is a complicated work because it was bent and formed, requiring skilled formwork It was.

  The present invention has been made in view of these problems. The purpose of the present invention is to form a curved surface easily by anyone without the need for skilled formwork when forming a partition wall or a mold having a curved surface. It is providing the board | plate material which can form.

In the plate material for solving the above problems, the surface side slits along the long side direction or the short side direction are formed at appropriate intervals on the surface of the foam resin plate main body, and are alternately positioned with the surface side slits. Back side slits along the long side direction or the short side direction are formed on the back side, and these front side slits and back side slits are flat V-shaped, and their tips are located behind the central axis of the plate thickness. The front side slit or the back side slit is provided with a reinforcing material so as to be removable. Moreover, it is included that the slits for joining are formed in the same direction as the front side slits or the rear side slits on both side surfaces of the plate body, both side surfaces of the front surface and the back surface.
Further, the plate material is formed with surface side slits along the long side direction or the short side direction at appropriate intervals on the surface of the plate material body made of foamed resin, and the back side of the position alternating with the surface side slits on the long side direction or short side. Back side slits along the side direction are formed, these front side slits and back side slits are flat V-shaped, the tip portion is located on the back side of the central axis of the plate thickness, and is formed in a curve, A fitting slit is formed on the front surface or the back surface between the front side slit or the back side slit, and a reinforcing material is detachably provided in the fitting slit.
Moreover, it is included that the slits for joining are formed in the same direction as the front side slits or the rear side slits on both side surfaces of the plate body, both side surfaces of the front surface and the back surface.

  Surface side slits along the long side direction or short side direction are formed at appropriate intervals on the surface of the foamed resin plate body, and along the long side direction or short side direction on the back surface at positions alternating with the surface side slits. By forming the rear-surface-side slit, the plate material can be freely bent to form an arbitrary curved shape. Further, since the plate material can be bent into, for example, a semicircular shape or a corrugated shape, a curved surface can be easily formed in the mold frame and the partition wall. Further, the front side slit and the rear side slit are V-shaped in a plane, and the tip portion is located on the back side with respect to the central axis of the plate thickness and is formed in a curved shape. The curvature is determined and the tip is not torn even when the V-shaped slit is opened. Moreover, the strength which can be used as a formwork or a partition wall can be obtained by providing the reinforcing material in the front side slit or the back side slit so as to be removable. Further, the plate materials can be easily connected to each other by the joining slits formed on both side surfaces of the plate material main body, both side surfaces of the front surface and the back surface, thereby forming a formwork or a partition wall.

  Hereinafter, embodiments of the plate material of the present invention will be described. In each embodiment, the same configuration is described with the same reference numeral, and different configurations are described with different reference numerals. This plate material is used when forming a curved formwork or a curved partition wall.

  1-4 is the board | plate material 1 of 1st Embodiment. The plate material 1 has a surface side slit 3 formed along the long side direction on the surface of a plate body main body 2 (appropriately thick rectangle) 2 made of thermoplastic foamed resin, and a back surface alternately positioned with the surface side slit 3. The back surface side slit 4 is formed along the long side direction, and a U-shaped reinforcing material 5 is fitted to the back surface side slit 4.

  As the thermoplastic foamed resin, a foamed product having a density of 8 to 40 g / l made of high density polyethylene, linear low density polyethylene, polypropylene, propylene / ethylene copolymer, or the like is used. These front-side slit 3 and back-side slit 4 are V-shaped, and their tip portions are located on the back side with respect to the center axis 6 of the plate thickness and are formed in a curved shape.

  When this tip portion is positioned on the back side of the center axis 6 of the plate thickness and overlapped with each other, as shown in (1) of FIG. Can be bent freely.

  Therefore, when the plate 1 is bent in one side, that is, in the direction in which the front side swells, as shown in FIG. 3 (2), the back side slit 4 is closed and the front side slit 3 is opened widely, but the tip is It is not torn. The extent 8 of the V-shaped opening of the slits 3 and 4 and the depth 9 determine the degree of bending of the plate 1, that is, the curvature. When these two are large, the curvature is large. When these two are small, the curvature is large. Becomes smaller.

  However, when the front end portions of the front surface side slit 3 and the back surface side slit 4 are located on the near side of the center axis 6 of the plate thickness, as shown in FIG. Since it is formed, folding becomes difficult.

  Further, a reinforcing material 5 is fitted into the back side slit 4 to maintain the strength of the curved plate 1. Therefore, when the front surface side is bent in the direction in which it swells, as shown in FIG. 5 (1), the reinforcing material 5 is fitted to the rear surface side slit (slit on the closing side) 4 and bent into a waveform. As shown in (2), the reinforcing material 5 is fitted into the front surface side slit 3 and the back surface side slit 4. Since the curved plate member 1 retains a predetermined strength by the reinforcing member 5, it is possible to form a barrier plate or a partition wall having a curved surface.

  Moreover, the slit 10 for joining is formed along the long side direction (same direction as the surface side and the back surface side slits 3 and 4) in the both-sides part in the both sides | surfaces, the surface, and the back surface of the board | plate material main body 2. Therefore, when the U-shaped connecting material 11 is fitted into the joining slit 10, as shown in FIG. 6, the plate materials 1 can be connected to each other on the side surface, and when the two plate materials 1 are connected, a large formwork 12 or partition wall is formed. 13 can be formed.

  These are joined by joining the connecting material 11 to the joining slits 10 at both ends, but as shown in FIG. 7 (1), the I-shaped joining material 14 is fitted into the joining slits 10 on both sides. They can also be joined together. Furthermore, as shown in (2) of the figure, it is also possible to join using the H-shaped connecting material 15 without using these joining slits 10. When the end portion of the plate member is fitted to the H-shaped connecting member 15, if the joining slit 10 is formed, the end portion is easily contracted, and after being fitted, it returns to its original state by a spring action. It becomes difficult to come off.

  8 and FIG. 9 show a curved partition wall 13 formed by inserting the plate material 1 into a ceiling-side runner 16 having a U-shaped cross section on the ceiling and a floor-side runner 17 having a U-shaped cross section on the floor. Since the plate material 1 is bent along the curved runners 16 and 17, the curved partition wall 13 is formed. Therefore, even if the runners 16 and 17 have other curved shapes, the partition wall 13 can be formed in any shape because the plate 1 is curved along the curved shapes.

  FIG. 10 shows a plate material 18 according to the second embodiment. This plate member 18 is obtained by making the reinforcing member 19 into a plane T shape, and the other configuration is the same as that of the plate member 1 of the first embodiment. In this structure, a fitting slit 20 is formed on the front and back surfaces between the front-side slit 3 and the back-side slit 4, and a vertical piece 21 of a reinforcing material is fitted to the fitting slit 20. The reinforcing member 19 is installed on the side opposite to the side that is curved and swells, and maintains the strength of the plate member 18 and is used as the mold frame 12 or the partition wall 13 as in the first embodiment. To do.

  In the above embodiment, since the reinforcing members 5 and 19 are detachable, for example, when the plate members 1 and 18 are used as a dam plate of the mold, the reinforcing material is set after the concrete placed in the mold is cured. 5 and 19 can be used as a heat insulating material when pulled out from the fitting slit 20.

  FIG. 11 shows the plate member 1 in which the reinforcing member 5 is fitted to the front side slit 3, and can be fitted to either of the slits 3 and 4. Further, in FIG. 12, the reinforcing member 5 is not a single piece (long shape) along the slits 3 and 4 as shown in FIG. It can also be provided at intervals. By dividing in this way, it is possible to install the reinforcing material 5 only in a necessary portion in the vertical direction.

  In the above embodiment, the front side slit 3 and the rear side slit 4 are formed along the long side direction of the plate body 2 (vertical direction in (2) of FIG. 1). The back surface side slit 4 can also be formed along the short side direction (lateral direction in FIG. 1 (2)), and this direction shall be determined as needed.

  The front surface side slit 3 and the back surface side slit 4 are formed along the same direction, and these are different directions (directions in which both intersect), that is, the front surface side slit (or back surface side slit) 3 is in the long side direction. The rear side slit (or front side slit) 4 is not formed along the short side direction.

  In the above embodiment, the plate members 1 and 18 in which the reinforcing members 5 and 19 are fitted to the front side slit 3 or the rear side slit 4 have been described. However, a plate member that does not fit the reinforcing members 5 and 19 is also formed. can do. The plate material that does not fit the reinforcing materials 5 and 19 has the same configuration as the plate material 1 of the first embodiment except that the reinforcing materials 5 and 19 are not fitted.
