Description

  [Technical Field] The present invention relates to a method of repairing a stair which covers an existing stair with a decorative member.

  Conventionally, there is known a method of repairing stairs that covers existing wooden steps with a flat plate-shaped new member (for example, Patent Document 1 and Patent Document 2). In many cases, the sinking and the slope of the risers are caused, and the new members have to be processed on site according to the size of the existing stairs. As a result, a gap may occur at the joint between the lower end of the member covering the riser and the member covering the tread, but if the color of the existing stairs and the color of the new member are significantly different, the gap will be noticeable , It took time to adjust the dimensions of new members to prevent gaps.

  On the other hand, in the new stairs, the lower end of the riser is joined without a gap by fitting the lower end of the riser, whose lower end is at an acute angle to the decorative surface, into the notch provided in the tread. In addition, a joint structure has been proposed to improve the design. (Patent Document 3)

  However, as in the invention described in Patent Document 1 and Patent Document 2, when covering the riser of the existing stairs, the decorative material grooved to receive the upper end portion of the decorative material covering the riser. Needs to be installed in the stair nose, and it takes time to manufacture the components. Moreover, although the center part of the existing tread has sunk downward due to aging, the cosmetic covering the tread and the cosmetic placed on the stair nose separate at the tread surface of the stairs. There is a high possibility of causing a catch or a step in the joint portion of the two cosmetic materials, which is dangerous. In addition, since the cosmetic materials are joined at a position where they are visible when going up the stairs, there is a possibility that the stairs user may have various impressions.

  Then, this invention is made in view of the subject mentioned above, Comprising: The existing stairs are easily coat | covered with a decorative member, and it aims at providing about the repair method of the stairs excellent in construction property and designability. .

  The first method for repairing stairs according to the present invention is a method for repairing a stair including an existing stair including a riser and a step board having a nose nose protruding from the riser with a plate-shaped decorative member, The decorative member has a top surface covering portion covering the top surface of the footboard, and a first member having a side surface covering portion extending downward from one end of the top surface covering portion to cover the side surface on the stair nose side, and faces the room. It has a second member which forms the lower end surface at an acute angle to the decorative surface and covers the riser, and a third member which covers the step of the tread plate, and the first member is stuck to the tread plate A lower end portion of the second member is fitted in a notch groove which is formed at one end opposite to the side surface covering portion side of the upper surface covering portion and which is narrower than a plate thickness of the second member; Bonding the two members to the kick plate and bonding the third member to the back of the step It is characterized in that the construction from the stage under the serial existing stairs in the order.

  A second method for repairing stairs according to the present invention is characterized in that the upper surface of the second member is formed at an acute angle with respect to the decorative surface.

  The method for repairing a stairway according to the present invention is characterized in that the side surface covering portion further covers a side surface of the third member opposite to the second member side.

  According to the first method of the present invention, the lower surface of the second member is formed at an acute angle to the decorative surface, and the upper surface covering portion of the first member is wider than the thickness of the second member on the decorative surface. The lower end of the second member slides to the decorative surface of the second member when the lower end of the second member is fitted into the notch groove, so the first member and the second It is possible to prevent a gap from being generated between members. In addition, since the third member is stuck on the back and back after the second member abuts on the kicking surface, the second member is the third member even if the sticking strength of the second member to the riser is weakened. You won't fall. Furthermore, since nails and screws are not used, the workability can be improved. And since each member is not joined by the tread surface, it is possible to improve the design without giving various impressions to the user when moving up and down the stairs.

  According to the second method of the present invention, since the upper end surface of the second member is formed at an acute angle with respect to the decorative surface, the lower end portion of the second member is fitted into the notch groove and the riser is formed. When turning to the side, the upper end portion of the second member and the step back can easily contact the riser without interference.

  According to the third method of the present invention, since the side covering portion further covers the side opposite to the second member side of the third member, the side of the third member is visually recognized when going up the stairs The design can be improved without giving various impressions to the user.

  Hereinafter, the best embodiment of the method of repairing stairs will be described with reference to the drawings. The stair improvement method is a method of covering the existing stairway 1 installed inside the building with a plate-like decorative member 2, and is suitably used mainly for the existing stairway formed of wooden straight stairs or stair stairs be able to. As shown in FIG. 1, the existing stairs 1 are supported by structural members (not shown) and close between the tread plates 11 and the tread plates 11 which are a plurality of horizontal members arranged at intervals in the height direction. The step nose 11 a of the step board 11 protrudes from the riser 12.

  As shown in FIG. 1 and FIG. 2, the decorative member 2 includes an elongated first member 21 having a substantially L-shaped side view and a riser 12 that covers the upper surface 11 b of the footplate 11 and the side surface 11 c on the step nose 11 a side. A long flat second member 22 to cover and a long flat third member 23 to cover the step back 11 d of the tread plate 11 are provided. In addition, although the decorative member 2 in case the existing stairs 1 are straight stairs is shown in FIG. 2, as the decorative member 2 is shown in FIG. 3, the shape of the 1st member 21 is deformed and it is a winding staircase. It can also be used for the existing stairs 1.

  The first member 21 includes an upper surface covering portion 21a covering the upper surface 11b of the step board 11, and a side surface covering portion 21b extending substantially perpendicularly from one end of the upper surface covering portion 21a to cover the side surface 11c on the step nose 11a side. Be done. Further, the upper surface covering portion 21a is formed with a plurality of non-slip grooves 21d extending in the longitudinal direction at an end portion on the side surface covering portion 21b side of the decorative surface 21c facing in the room and at an end portion opposite to the side surface covering portion 21b. The notch groove 21e for inserting the lower end part of the 2nd member 22 is formed.

  As shown in FIGS. 2 to 5, the second member 22 is a long flat plate member, and the lower end surface 22 a and the upper end surface 22 b are formed at an acute angle with respect to the decorative surface 22 c facing the room. The thickness t1 of the second member 22 shown in FIG. 4 is not particularly limited. However, when the second member 22 is inserted into the notch groove 21e and rotated toward the riser 12 side, it contacts the riser 12 It has a contact thickness.

  As shown in FIG. 4, the notch groove 21e is formed with a width W1 narrower than the plate thickness t1 of the second member 22, and when the lower end of the second member 22 is fitted into the notch groove 21e, the lower end surface 22a partially protrudes from the notch groove 21e. Further, the notch groove 21e is formed to have a groove height H1 longer than the insertion depth H2 of the second member 22 when the lower end portion of the second member 22 is inserted into the notch groove 21e. The lower end of the second member 22 does not abut on the bottom surface of the notch groove 21e. Although the width W1 and the groove height H1 of the notch groove 21e are not particularly limited, for example, when the plate thickness t1 of the second member 22 is about 7 mm, the width W1 is about 3 mm and the groove height H1 is about 5 mm. be able to. With such dimensions, the existing stair 1 can be used safely without the lower end portion of the second member 22 being removed from the notch groove 21 e by vibration even if a person repeatedly moves up and down the existing stair 1. Further, by setting the thickness t2 of the upper surface covering portion 21a to about 1.5 times to 2 times the groove height H1, it is possible to prevent a crack in the notch groove 21e. Furthermore, as shown in FIG. 5, when the third member 23 is attached to the step back 11 d, the side surface covering portion 21 b closely covers the side surface 23 a of the third member 23 opposite to the second member 22. It has a length.

  Next, the repair procedure of the stairs which coats the existing stairs 1 with the decorative member 2 will be described. The covering of the existing stairway 1 with the decorative member 2 is performed from the lower side. First, a double-sided tape is attached to the surface of the first member 21 opposite to the decorative surface 21c and an adhesive is applied, and as shown in FIG. The first member 21 is attached to the tread 11 in such a manner that the first member 21 is aligned with the protruding corner portion. By bonding the first member 21 to the tread 11 in combination with a double-sided tape and an adhesive, the first member 21 can be firmly fixed to the existing staircase 1.

  Then, as in the first member 21, a double-sided tape is attached to the surface of the second member 22 opposite to the decorative surface 22c, and an adhesive is applied, and as shown in FIGS. 7 and 8A, the second member The lower end portion of the second member 22 is fitted in the notch groove 21e while inclining the second member 22 so that the upper end portion of the second member 22 separates from the riser 12, and the second end of the second member 22 is centered The upper end of the member 22 is pivoted in the direction approaching the riser 12. At this time, the lower end portion of the second member 22 whose plate thickness is larger than the width W1 of the notch groove 21e can not be completely inserted into the notch groove 21e, and the groove depth H1 of the notch groove 21e is Since it is longer than the insertion depth H2 of the second member 22, a space S is formed between the lower end portion of the second member 22 and the bottom of the notch groove 21e as shown in FIG. Then, as shown in FIGS. 8B to 8D, the lower end surface 22b is slid downward so that the decorative surface 22c abuts on the corner of the notch groove 21e on the opposite side to the riser 12. The second member 22 is further rotated to stick the back surface of the second member 22 to the riser 12. Thus, since the space S is formed between the lower end portion of the second member 22 and the bottom surface of the notch groove 21e, the tread plate 11 has sunk downward or the riser 12 is inclined due to aging. However, the second member 22 can be attached to the riser 12 by absorbing the distortion.

  Further, as described above, since the upper end surface 22b of the second member 22 forms an acute angle with the decorative surface 22c, the second member 22 can easily be the riser 12 without interfering with the step back 11d. It can be made to abut on, and the squeeze due to the upper end portion interfering with the step back 11d when moving up and down the stairs can be reduced. Furthermore, since the thickness t1 of the second decorative member 22 is larger than the width W1 of the notch groove 21e, when the second member 22 is brought into contact with the riser 12 as shown in FIG. The lower end surface 22b of the member 22 can be prevented from sliding toward the decorative surface 22c to form a gap between the first member 21 and the second member 22.

  Then, as shown in FIG. 9, the third member 23 is attached to the step back 11d projecting from the decorative surface 22c of the second member 22 with a double-sided tape, and the steps above the existing step 1 are also the decorative member 2 in the same procedure. Cover with At this time, as shown in FIG. 5, the side surface covering portion 21b of the first member 21 is a side surface 23a of the third member 23 opposite to the second member 22 when the third member 23 is attached to the step back 11d. The side 23a is not exposed when the user climbs the stairs because it has a length covering the upper end of the stair. In addition, since the third member 23 is fixed after the second member 22 is installed, the second member 22 is suppressed to the third member 23 even if the adhesion of the second member 22 to the riser 12 is weakened. Being prevented from falling to the tread 11 side. Therefore, it is necessary to fix the second member 22 to the riser 12 with a nail or a screw, or to provide a groove into which the upper end of the second member 22 is inserted in the step 11d of the tread plate 11 located above the second member 22. There is no need for installation, and the installation can be improved by omitting the installation work.

  Further, since the side surface 23a of the third member 23 is covered by the side surface covering portion 21b, and the first member 21 and the third member 23 are not joined at the tread surface, the first member 21 and the third member 23 are There is no catching or step on the joint, and the user can use the existing stairs 1 covered with the decorative member 2 safely, and there is no possibility that the image will be deteriorated due to various impressions. . And since the decorative member 2 is divided into two members without using the first member 21 and the third member 23 as one member, the decorative member 2 can be easily manufactured according to the step board 11 of various dimensions. Therefore, the method of modifying a stair according to the present invention can be suitably used for a stair where it is difficult to adjust the size of each part.

  Further, the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately modified without departing from the scope of the concept of the present invention.

  The method of repairing a stair according to the present invention can be suitably used in existing existing stairways.
