  FIG. 1 is a side sectional view showing a corrugated board 1 according to an embodiment of the present invention. In the present specification, the left side of FIG. 1 is described as the front side or the front end side, and the right side is described as the rear side or the base end side.

  As shown in the figure, the step board 1 is used for a wooden indoor staircase of a general house. The corrugated board 1 includes a substrate 10.

  A non-slip mounting groove 16 extending continuously along the substrate length direction (step width direction) is formed in the front portion of the upper surface (plate surface) of the substrate 10. Further, a kick groove 19 extending continuously in the substrate length direction (step width direction) is formed in the front portion of the lower surface of the substrate 10.

  The nose 11 is the front end of the substrate 10. In particular, in the present embodiment, the upper surface of the nose 11 is a portion in front of the non-slip mounting groove 16 on the upper surface side of the substrate 10, and the lower surface of the nose 11 is in front of the kick groove 19 in the lower surface of the substrate 10. It is a part of. Needless to say, the front end surface of the nose 11 is the front end surface of the substrate 10.

  Further, the front end surface of the nosing 11 constitutes a finding surface 12, and the lower surface of the nosing 11 constitutes a facing surface 13.

  Further, in the present embodiment, the range in which the non-slip mounting groove 16 is formed is referred to as the rear edge of the nose 11 on the upper surface side of the board, and the range in which the kick groove 19 is formed is behind the nose 11 on the lower surface side of the board. It is called an edge.

  The top decorative sheet 2 is attached to the top surface 14 of the substrate 10 except for the non-slip mounting groove 16 portion.

  Further, a continuous nosing decorative sheet 3 is attached to the turning surface 13, the finding surface 12 and the upper surface of the nosing 11 in the substrate 10 so as to cover the nosing 11.

  In addition, since the thickness of the decorative sheets 2 and 3 is about 0.1 mm to 0.5 mm and the thickness of the substrate 10 is about 30 mm to 40 mm, the decorative sheets 2 and 3 are difficult to represent in the drawing at the actual scale. However, in FIG. 1, the thickness of the decorative sheets 2 and 3 is exaggerated for easy understanding of the invention (the same applies to FIGS. 2 to 5 below).

 Below, the detailed structure of the corrugated board 1 of this embodiment is demonstrated according to a manufacture procedure.

  First, as shown in FIG. 2, the upper decorative sheet 2 is attached to a required region on the upper surface of the substrate base material 10a to obtain an upper decorative sheet (upper decorative process).

  In this embodiment, as a base material 10a, a plywood, LVL, medium specific gravity fiber board (MDF), or these composite boards, for example, the thing which stuck MDF on the plywood, etc. can be used conveniently.

  As the upper decorative sheet 2, a veneer, an olefin-based (polypropylene, polyethylene, or the like) resin sheet, a polyvinyl chloride sheet, paper, a resin-impregnated paper, or the like can be suitably used.

  After the upper surface decorative process is completed, the upper decorative base material is cut (cut) into a predetermined corrugated board shape to obtain a substrate (upper decorative sheet) on which the upper decorative sheet 2 is attached to the entire upper surface (cutting process). ).

  In the present embodiment, what is obtained by cutting the base material 10a into a predetermined stepped plate shape is referred to as a substrate 10. Needless to say, the base material 10a and the substrate 10 are made of the same material.

  For example, as the step plate 1 for a straight staircase, the substrate 10a is cut into a rectangle in plan view to obtain a rectangular substrate 10.

  In addition, as shown in FIG. 11, the two-stage rotating staircase includes two substrates 10 and 10 having a right-angled isosceles triangle shape in plan view so that a square plate is formed as a set of two pieces. ing. Further, as shown in FIG. 12, the five-step rotating staircase includes five substrates 1 of a plurality of types in a plan view so that a rectangular plate material is formed by combining five.

  In the present invention, the shape of the step plate 1 (substrate 10) is not particularly limited. The substrate 10 for a corrugated board of the present invention includes a substrate having a shape used for a three-stage rotation type, a four-stage rotation type, a four-stage deformation rotation type, and the like in addition to those already described.

  For reference, in the present invention, as the various step plates 1, one having a thickness of 30 mm to 40 mm can be suitably used.

  Furthermore, as the step plate 1 of the straight staircase, one having a width (dimension in the length direction) of 900 mm to 1200 mm and a depth (dimension in the front-rear direction) of 220 mm to 270 mm can be suitably used.

  Further, as the step plate 1 of the two-stage type or the three-stage type, a plate having a shape obtained by dividing a 900 mm × 900 mm to 1200 mm × 1200 mm plate into two or three parts can be suitably used. As the deformed four-stage type and five-stage type corrugated plate 1, a plate having a shape obtained by dividing a 900 mm × 1800 mm to 1000 mm × 2000 mm plate into four or five can be suitably used.

  Furthermore, as the corrugated board 1 for landings, the board of 900 mm x 900 mm-1200 mm x 1200 mm can be used conveniently.

  Further, in the present invention, the front end position of the top decorative sheet 2 is arranged between the front end position of the nose 11 and the rear end position of a region (non-slip mounting region 15) where a non-slip mounting groove 16 described later is formed. It ’s fine. That is, the top decorative sheet 2 does not necessarily have to be provided over the entire top surface of the substrate 10, and may be pasted except for the region of the front end portion on the top surface of the substrate 10.

  After the cutting step is completed, as shown in FIG. 4, the non-slip attachment region 15 in the top decorative plate is cut to form the non-slip attachment groove 16 (upper surface side grooving step). Further, along with this upper surface side grooving step, the portion of the upper decorative sheet 2 attached to the non-slip region 15 is also removed by cutting.

  The non-slip mounting groove 16 is formed continuously along the length direction (step width direction) of the substrate 10.

  After the upper surface side grooving step is completed, as shown in FIG. 5, the nose decorative sheet 3 is attached to the nose 11 of the upper decorative plate to obtain the upper nose decorative plate (nosing decorative step).

  The nosing decorative sheet 3 is affixed to the upper surface, the finding surface 12 and the facing surface 13 of the nosing 11. This nosing decorative sheet 3 is composed of a single continuous sheet, and is arranged to wrap the nosing 11.

  The rear end edge on the upper surface side of the nosing decorative sheet 3 is attached to the inner peripheral surface of the non-slip mounting groove 16. Further, the rear end edge of the lower face side of the nosing decorative sheet 3 is arranged in the lower nose rear end edge of the lower face side, that is, in a region where a kick groove 19 described later is formed.

  In the present invention, the rear end edge on the lower surface side of the nosing decorative sheet 3 may be arranged behind the region where the kick groove 19 is formed, or may be arranged forward. However, as will be described later, in order to improve the fit of the lower side rear end edge of the nosing decorative sheet 3, the lower side rear end edge of the nosing decorative sheet 3 is within the region where the kick groove 19 is formed, or more Is also preferably arranged rearward.

  In this embodiment, the nosing decorative sheet 3 is one in which paper or non-woven fabric is pasted on the back surface of the veneer, and an olefin-based (polypropylene, polyethylene, etc.) resin sheet or polyvinyl chloride sheet is stuck on the surface of the veneer. An olefin-based resin sheet, a polyvinyl chloride sheet, or a sheet having a resin sheet attached to the surface of paper can be suitably used.

  Further, the coloring and painting of the top decorative sheet 2 and the nosing decorative sheet 3 may be performed before or after the sheets 2 and 3 are adhered to the substrate 10 (base material 10a).

  For example, when using a nose decorative sheet 3 with a paper or nonwoven fabric pasted on the back surface of the veneer, the top decorative sheet 2 and the nose decorative sheet 3 are pasted on the substrate 10 (base material 10a), Both sheets 2 and 3 are preferably colored or painted.

  Furthermore, when using the thing which stuck the olefin resin sheet or the polyvinyl chloride sheet on the surface of the veneer as the nosing decorative sheet 3, the upper decorative sheet 2 and the nosing decorative sheet 3 are colored or painted in advance. The upper decorative sheet 2 and the nose decorative sheet 3 are preferably attached to the substrate 10 (base material 10a).

  In the present embodiment, the nose makeup step may be performed before the upper surface side grooving step. That is, after pasting the nosing decorative sheet 3 on the nose 11 of the top decorative plate, the non-slip mounting region 15 in the substrate 10 is cut to form the non-slip mounting groove 16 (upper surface side grooving step). In the upper surface side grooving step, with the formation of the non-slip attachment groove 16, the portion attached to the non-slip attachment region 15 in the upper decorative sheet 2 and the nose decorative sheet 3 is also removed by cutting.

  Next, as shown in FIG. 1, the rear edge of the nose 11 on the lower surface of the substrate 10 is cut to form a kick groove 19 (lower surface side grooving step). In this lower surface side grooving step, the rear end edge on the lower surface side of the nosing decorative sheet 3 is also removed by cutting. However, in the present invention, the nose decorative sheet 3 is not removed when the lower end side rear edge of the nose decorative sheet 3 is disposed forward of the position where the kick groove is to be formed.

  The kick groove 19 is formed continuously along the length direction (step width direction) of the substrate 10.

  In the present invention, the lower surface side grooving step may be performed prior to the upper surface side grooving step.

  Next, the non-slip 5 is fitted and fixed in the non-slip mounting groove 16 to obtain the corrugated plate 1 of the present embodiment (non-slip mounting step).

  As shown in FIGS. 6 and 7, the non-slip 5 functioning as an anti-slip is constituted by a molded product such as a soft synthetic resin or synthetic rubber having elasticity and softness and having a large friction coefficient.

  The non-slip 5 of the present embodiment includes a non-slip main body 51 provided on the upper side thereof, and two leg portions 55 and 55 that are integrally formed on the lower surface side of the non-slip main body 51 and constitute an elastic contact portion. Yes.

  The front-rear dimension of the non-slip main body 51 (the dimension in the left-right direction in FIG. 7) is slightly smaller than the width of the non-slip mounting groove 16 so that the non-slip main body 51 is accommodated in the non-slip mounting groove 16 in an adapted state. It has become. Furthermore, the upper surface (upper end surface) 52 of the non-slip main body 51 is formed as a flat inclined surface (front inclined surface) that is inclined forward so that the front end side is lower than the rear end side.

  Further, the front surface 53 and the rear surface 54 of the non-slip main body 51 are configured to be vertical surfaces when assembled to the corrugated plate 1.

  Further, the upper front end corner portion 51a of the non-slip main body 51 is formed in an arc shape having a curvature radius of 0.5 mm to 1.5 mm, and the upper rear end corner portion 51b has a curvature radius of 0.2 mm to 1.2 mm. It is formed in a circular arc shape.

  In the present embodiment, as shown in FIG. 7, the boundary position between the non-slip main body upper surface 52 as a flat surface and the upper front end corner portion 51a as a curved surface is defined as an upper surface front end position 52a, and the non-slip main body upper surface 52 and the curved surface The height difference H between the upper surface front end position 52a and the upper surface rear end position 52b is set to 0.4 mm to 1.0 mm with the boundary position with the upper rear end corner portion 51b as the upper surface rear end position 52b.

  Here, in the present embodiment, the upper surface 52 of the non-slip main body 51 is constituted by a surface that does not include the surface of the upper front end corner portion 51a and the surface of the upper rear end corner portion 51b. Therefore, the front end of the upper surface 52 is the upper surface front end position 52a, and the rear end of the upper surface 52 is the upper surface rear end position 52b.

  The leg portions 55 and 55 of the non-slip 5 are configured to be elastically deformable inward. Further, three retaining fins 56 are integrally formed on both the front and rear sides of the leg portions 55 and 55, respectively.

  The tip of each retaining fin 56 is disposed so as to protrude forward and rearward from the front surface 53 and the rear surface 54 of the non-slip main body 51 in a natural state.

  When the non-slip 5 is fitted into the non-slip mounting groove 16 of the corrugated plate 1, the leg portions 55 and 55 are elastically deformed inward, and the retaining fins 56 are also elastically deformed inward. Therefore, in this state, the retaining fins 56 are brought into close contact with the inner peripheral side surface of the non-slip mounting groove 16 by the elastic repulsive force of the leg portions 55 and 55 and the retaining fins 56. As a result, the non-slip 5 is not easily detached from the non-slip mounting groove 16.

  Needless to say, the non-slip 5 can be removed from the non-slip mounting groove 16 by scraping the non-slip 5 out of the non-slip mounting groove 16 with a tool such as a screwdriver.

  In the present embodiment, when the non-slip 5 is fitted in the non-slip attachment groove 16 and attached, the upper front end position 52a of the non-slip main body 51 is substantially the same height as the upper surface 14 of the corrugated plate 1 (the upper surface of the nose decorative sheet 3). Is set. Further, the upper surface rear end position 52b of the non-slip main body 51 is disposed so as to protrude above the upper surface 14 of the corrugated board 1 (the upper surface of the upper decorative sheet 2). Accordingly, the rear surface 54 of the non-slip main body 51 is configured as a vertical wall surface that stands vertically with respect to the upper surface 15 of the corrugated plate 1.

  In the present embodiment, the upper surface front end position 52a of the non-slip main body 51 is set at substantially the same height as the upper surface 14 of the corrugated board 1, and therefore the upper surface front end position with respect to the upper surface of the corrugated board 1 (surface decorative sheet 2). The height of 52a is equal to the height difference H between the upper surface front end position 52a and the upper surface rear end position 52b described above.

  Here, in the present embodiment, the height of the upper surface rear end position 52b of the non-slip main body 51 is preferably set to be 0.2 mm to 0.8 mm higher than the height of the upper surface of the corrugated plate. That is, when the height of the upper surface rear end position 52b is lower than the above specified range, the anti-slip effect may be slightly reduced. Assembling work to the side plate 6 may be difficult.

  Further, as described later, the upper surface front end position 52a is preferably set to be lower or equivalent to the upper surface of the step plate in consideration of workability at the time of stair assembly. Specifically, the height of the upper surface front end position 52a is preferably set to be 0.2 mm to 0 mm lower than the height of the upper surface of the step board.

  The inclination angle of the upper surface 52 of the non-slip 5 with respect to the step plate upper surface 15 is set to 6 ° to 15 °. In the present embodiment, when the inclination angle is smaller than the specified range, the anti-slip effect may be slightly reduced. When the inclination angle is larger, as will be described later, to the side plate 6 of the step plate 1 at the time of stair assembly. Assembling work may be difficult.

  As described above, according to the corrugated board manufacturing method of the present embodiment, the top decorative sheet 2 is attached to the top surface of the base material 10a and cut into a predetermined shape to obtain a top decorative sheet, and the top decorative sheet A nose decorative sheet 3 is pasted so as to cover the nose 11 of the board. That is, since the upper surface decorative sheet 2 is only attached on the plane which is the upper surface of the base material 10a, it can be easily attached. Further, since the nosing decorative sheet 3 is attached so as to cover only the nosing 11 of the substrate 10, it can be easily pasted without changing the setup, regardless of the shape of the substrate 10. Can do. Thus, the decorative sheets 2 and 3 can be easily and efficiently attached without changing the setup, and the corrugated board 1 can be manufactured efficiently.

  Furthermore, it arrange | positions so that the upper surface side edge of the nosing decorative sheet 3 may be turned around to the inner side of the non-slip attachment groove 16. For this reason, when the non-slip 5 is fitted into the non-slip mounting groove 16, the rear edge on the upper surface side of the nosing decorative sheet 3 is pushed into the non-slip mounting groove 16 by the non-slip 5, so The rear edge fits nicely at the front end position of the non-slip mounting groove 16, and the edge corresponding to the rear end position of the non-slip mounting groove 16 in the top decorative sheet 2 (the front edge of the exposed portion in the top decorative sheet 2) is also provided. It fits nicely. As described above, the edges of the decorative sheets 2 and 3 fit nicely, so that a good finish can be obtained.

  Further, the rear end edge on the upper surface side of the nosing decorative sheet 3 is suppressed by the non-slip main body front surface 53 of the non-slip 5, and the front end edge of the exposed portion in the upper decorative sheet 2 is suppressed by the non-slip main body rear surface 54 of the non-slip 5. For this reason, it is possible to effectively prevent a problem that the edges of the decorative sheets 2 and 3 are peeled off, and to obtain a satisfactory finish more reliably.

  In the present invention, the upper edge of the nosing decorative sheet 3 does not necessarily have to be disposed so as to go around into the non-slip mounting groove 16, and may be disposed at the opening edge of the non-slip decorative groove 16. Also in this case, since the upper surface side rear end edge of the nose decorative sheet 3 can be suppressed by the front surface 53 of the non-slip 5, the upper surface side rear end edge of the nose decorative sheet 3 can be satisfactorily fit, peeled, etc. It is also possible to reliably prevent such problems.

  Further, in the present embodiment, also on the lower surface side of the step plate, the kick groove 19 is formed so as to cut out the rear end edge on the lower surface side of the nose decorative sheet 3. For this reason, as will be described later, by inserting the kick plate 7 into the kick groove 19, the lower end of the nose decorative sheet 3 looks nicely at the front end position of the kick groove 19, and a good finish is obtained. be able to.

  In addition, since the nose 11 of the substrate 10 is wrapped by one continuous nosing decorative sheet 3, the nosing decorative sheet 3 is disposed across the entire area from the upper surface to the lower surface of the nosing 11 without any breaks, and the finish is more reliably improved. Can be obtained.

  Next, a procedure for assembling an indoor staircase using the step board 1 of the present embodiment will be described.

  FIG. 8 is a perspective view showing a straight staircase assembled using the step board of the embodiment, FIG. 9 is an inner side view showing a side plate used for the straight staircase of the embodiment, and FIG. 10 is a key of the straight staircase of the embodiment. It is a notch perspective view which shows a part.

  As shown in these drawings, this staircase includes a plurality of step plates 1, a pair of side plates (both side plates) 6, 6 and a plurality of kick plates 7 as basic components.

  Both side plates 6 and 6 support the step plate 1 and are fixed to the housing (structure) of the house so as to be arranged along both sides of the staircase construction position.

  A plurality of step plate mounting grooves 61 are formed along the horizontal direction at predetermined intervals on the inner side surfaces of the side plates 6 and 6 corresponding to the mounting positions of the step plates 1. Each step plate mounting groove 61 has a rear end opened rearward on the back side of the staircase, and both edge measuring portions of the step plate 1 can be inserted into the step plate mounting groove 61 from the rear end opening portion.

  Further, a plurality of kick plate mounting grooves 62 are formed on the inner side surfaces of the side plates 6 and 6 along the vertical direction at predetermined intervals corresponding to the mounting position of the kick plate 7. Each kick plate mounting groove 62 is disposed so as to extend downward from the tip of each step plate mounting groove 61, and has an upper end communicating with the step plate mounting groove 61 and a lower end downward on the back side of the staircase. It is open towards. Further, both ends of the kick plate 7 can be inserted into the kick plate mounting groove 62 from the lower end opening portion.

  The plurality of corrugated plates 1 are inserted and attached to the plurality of sets of corrugated plate mounting grooves 61, 61 corresponding to each other between the side plates 6, 6, respectively, and the corresponding plural sets of kick plate mounting grooves 62, A plurality of kick plates 7 are inserted into 62 and attached from below. The stairs are assembled in this way.

  By the way, when the upper end portion of the non-slip 5 protrudes from the upper surface of the step plate 1 as in this embodiment, when the step plate 1 is inserted into the step plate mounting groove 61 of the side plate 6, the upper end portion of the non-slip 5 It is assumed that the assembling work of the corrugated plate 1 cannot be smoothly performed by striking the upper wall surface of the corrugated plate mounting groove 61.

  In view of this, in the step plate 1 of the present embodiment, the upper surface 52 of the non-slip 5 is formed as an inclined surface that is inclined forward, so that the upper surface 52 of the non-slip 5 is inserted when the step plate 1 is inserted into the step plate mounting groove 61. However, it is guided by the upper wall surface without protruding to the upper wall surface of the corrugated plate mounting groove 61, and is elastically compressed and deformed so that the upper end portion of the non-slip 5 is recessed downward. Therefore, the upper surface 52 of the non-slip 5 does not come into strong contact with the upper wall surface of the step plate mounting groove 61, and the insertion work of the step plate 1 into the step plate mounting groove 6 can be performed easily and reliably, and efficiently. You can assemble stairs.

  In the present invention, the upper surface front end position 52a of the non-slip 5 does not necessarily have to be set at the same height with respect to the upper surface 14 of the step plate 1. The upper surface front end position 52a of the non-slip 5 is not necessarily set to the upper surface 14 of the step plate. Alternatively, it may be set low or high.

  Of course, in the present invention, the position of the upper surface front end position 52a of the non-slip 5 is set to be equal to or lower than the upper surface 14 of the step plate, thereby further smoothly inserting the step plate 1 into the step plate mounting groove 61. It can be carried out.

  Moreover, since the non-slip 5 is arrange | positioned at the upper surface front part of each step board 1, the step assembled in this embodiment, when going up and down the stairs, the sole is in close contact with the upper end of the non-slip 5; It is possible to reliably prevent slipping.

  In particular, in the present embodiment, the upper surface rear end position 52b of the non-slip 5 is disposed so as to protrude upward from the upper surface of the step board 1, so that the sole of the foot is more reliably attached to the upper surface rear end position 52b. It can be made to adhere and a sufficient anti-slip effect can be obtained.

  In addition, in the present embodiment, the rear surface 54 of the non-slip 5 protrudes upward from the upper surface of the step plate 1 and is formed on the vertical wall surface, so that the forward sliding is more reliably prevented by the vertical wall surface. And a sufficient anti-slip effect can be obtained more reliably.

  As described above, according to the stairs of this embodiment, a sufficient anti-slip effect can be obtained, so that the stairs can be smoothly moved up and down without difficulty.

  The present invention is not limited to a straight staircase step board, and can also be applied to various staircase steps.

  Furthermore, the present invention includes a plate used for a landing, which is also included in the step plate, and can also be applied to this step plate.

  In the above embodiment, the upper decorative sheet is attached to the base material, and then the base material is cut to produce the upper decorative board. However, the present invention is not limited to this, and in the present invention, the base material is specified. After the substrate is cut into a shape (stepped plate shape), an upper decorative sheet may be attached to the upper surface of the substrate.

  In the above embodiment, the upper surface of the non-slip is constituted by a flat inclined surface. However, the present invention is not limited to this. In the present invention, the upper surface of the non-slip is gently inclined, for example, a large curvature radius. You may make it comprise with a concave surface or a convex surface. When the non-slip upper surface is configured as a concave surface or a convex surface, the inclination angle of the straight line (flat surface) connecting the non-slip upper surface front end position and gradual surface rear end position with respect to the stepped plate upper surface in the side surface sectional state is set. What is necessary is just to treat as the inclination angle of a non-slip upper surface.

  Further, in the above embodiment, a non-slip mounting groove is formed at the rear edge (non-slip mounting region) of the nose on the upper surface of the substrate, and the non-slip is fitted and fixed in the groove. In the present invention, the non-slip mounting groove is not necessarily formed. For example, without forming a non-slip mounting groove on the rear edge of the nose on the upper surface of the substrate, directly apply non-slip so as to cover the front edge of the exposed part of the upper decorative sheet and the upper edge of the upper nose decorative sheet. You may make it attach. Further, a decorative material may be provided on the rear edge of the nose on the upper surface of the substrate. In this case, non-slip may be provided in another region.
