JP 09-125643 A Japanese Patent Laid-Open No. 09-096073

  As in the staircase covering structure of Patent Document 1, the step surface covering portion of the staircase covering material is adhered to the tread surface of the stair base with an adhesive, and the adhesive is applied to the tread surface of the stair base to provide an open time. Therefore, it takes time and labor, and the workability is somewhat difficult. On the other hand, what sticks most of the staircase covering material to the staircase foundation with the adhesive layer as in the staircase covering structure of Patent Document 2 is provided on the back surface of the staircase covering material in advance. By simply pressing the stair covering material against the stair base, it can be attached easily, and the above-mentioned labor and time can be saved.

  However, when sticking the tread covering part of the stair covering material to the stair base with the adhesive layer, once the adhesive layer on the back of the stair covering material is in contact with the stair base, the stair covering material is Therefore, there is a problem that it is difficult to perform the fine adjustment by repositioning the stair covering material or slightly shifting the position of the stair covering material.

  The present invention has been made to cope with the above-mentioned problem, and the problem to be solved is to stick the tread surface covering portion to the tread surface of the staircase foundation with an adhesive such as an adhesive. In spite of this, it is an object of the present invention to provide a stair covering material excellent in workability capable of easily performing positioning work, re-positioning work, and fine adjustment work of the position, and a stair covering method using this stair covering material.

  In order to solve the above-mentioned problems, a staircase covering material according to the present invention is a staircase covering material bent in an inverted L shape that covers a tread surface, a nose, and a raised surface of a stair base, and the tread surface covering portion thereof An adhesive layer is formed on the lower surface of the adhesive layer, a net is partially laminated on the lower surface of the adhesive layer, and a release paper covering the network and the adhesive layer is further laminated. To do.

In the staircase covering material of the present invention, it is desirable that the net-like body is laminated over substantially the entire width of the lower surface of the adhesive layer near the nose covering portion.
And it is desirable for the area of the lamination | stacking area | region of the said mesh body to be 1/10-1/2 of the area of the said adhesive agent layer.
Furthermore, it is desirable that the release paper can be divided at a portion corresponding to the layered region of the mesh body.

  Further, the staircase covering method according to the present invention is a staircase covering method in which the staircase base is covered with the above staircase covering material according to the present invention, and the release paper in a portion corresponding to the laminated region of the mesh body is peeled off. Then, the staircase covering material is overlaid on the staircase foundation, the staircase covering material is properly positioned, and then the net layer laminated region of the tread surface covering portion of the staircase covering material is pressed and adhered to the tread surface of the staircase foundation, Further, the remaining release paper is peeled off, and the entire tread surface covering portion of the staircase covering material is adhered to the tread surface of the staircase foundation.

  The term “sticking” as used in the present invention is a conceptual term that encompasses both adhesion and adhesion.

  The stair covering material of the present invention is a part of the release paper covering the laminated mesh body, that is, the part of the release paper corresponding to the laminated area of the mesh body is peeled to expose the mesh body, and the stair covering material is provided on the stair base. In this state, the exposed network and the remaining unpeeled release paper only touch the tread on the staircase, and the adhesive layer does not touch the tread on the staircase. The covering material can be moved to be positioned at an appropriate position, repositioned, or finely adjusted. Next, when the mesh layered region of the tread surface covering portion of the stair covering material is pressed against the tread surface of the stair base material, the adhesive layer is partially pushed out to the stair base side through the opening of the net material, or the net material is After sinking into the adhesive layer, the adhesive layer and the staircase substrate come into contact with each other, and the net-like layered region of the tread surface covering portion of the staircase covering material is adhered to the staircase substrate. Then, when the release paper of the portion covering the adhesive layer other than the reticulated layer layer is peeled and the entire tread surface covering portion of the stair covering material is pressed against the tread surface of the stair base material, the staircase covering to the tread surface of the stair base material Adhesion of the tread surface covering portion of the material is completed.

  As described above, the staircase covering material of the present invention attaches the tread surface covering portion to the tread surface of the staircase base by the adhesive layer formed on the lower surface thereof, so that it takes time and effort to apply adhesive. Time setting is unnecessary, and as described above, positioning work for the staircase covering material, repositioning work, fine adjustment work for the position, etc. can be easily performed, so that the workability is excellent. The staircase covering method can be implemented efficiently.

  Further, in the staircase covering material of the present invention, the one in which the net-like body is laminated over substantially the entire width on the portion near the nose covering portion on the lower surface of the adhesive layer is the first nose covering of the tread covering portion of the staircase covering material. Since the portion close to the portion can be positioned and pasted and fixed over substantially the entire width, positioning work can be easily performed and positioning can be performed accurately. When attaching staircase covering material, it is important that the nose of the staircase foundation and the staircase covering portion of the staircase covering material are in an appropriate positional relationship. If the load of the person who moves up and down is repeatedly applied to the nose covering part of the staircase covering material, it may cause problems such as cracks in the nose covering part or damage to the nose covering part. When positioning and sticking and fixing the portion near the nose covering part of the tread surface covering part over almost the entire width, make sure that the nose of the staircase foundation and the nose covering part of the staircase covering material are in an appropriate positional relationship Since the staircase covering material can be accurately positioned, the above-described problems do not occur.

  The layered area of the net-like body has a slightly lower adhesive strength than the other areas, but the staircase covering material in which the area of the layered area of the net-like body is 1/10 to 1/2 of the area of the adhesive layer Since practically sufficient adhesion strength can be obtained, there is no fear that the tread surface covering portion of the stair covering material will be peeled off from the tread surface of the stair base. If the area of the layered region of the mesh is larger than ½ of the area of the adhesive layer, the adhesive strength may be insufficient, and the amount of the mesh used may increase, resulting in high costs. . On the other hand, when the area of the mesh layer is smaller than 1/10 of the area of the adhesive layer, the stair covering material is first positioned to attach and fix the mesh layer when the mesh layer is pasted. There is a risk that the wearing strength will be insufficient, and the stair covering material will move, making accurate positioning difficult.

  Further, the staircase covering material in which the release paper can be divided at the portion corresponding to the laminated area of the mesh body is peeled and removed while dividing the release paper at the portion corresponding to the laminated area of the mesh body, so that the network body is separated. Since it can be easily exposed, workability is very good.

  Further, the staircase covering method according to the present invention uses the above-mentioned staircase covering material, peels off the release paper of the portion corresponding to the layered area of the mesh body, and superimposes the staircase covering material on the staircase foundation, so that the staircase covering material is appropriate. After positioning, the mesh layered region of the tread covering part of the staircase covering material is pressed against the tread surface of the stair base, and then the remaining release paper is peeled off to cover the tread surface of the stair covering material. Since the entire part is attached to the tread surface of the staircase, there is no need to apply adhesive or set the open time, and the positioning work, repositioning work, and fine positioning of the staircase covering material are not required. Since adjustment work etc. can be performed easily and correctly, it is excellent in workability and can be implemented efficiently.

  Hereinafter, each embodiment of the staircase covering material and the staircase covering method according to the present invention will be described in detail with reference to the drawings.

  1 is a cross-sectional view of a staircase covering material according to an embodiment of the present invention, FIG. 2 is a perspective view of the staircase covering material turned upside down, FIG. 3 is a bottom view of the staircase covering material, and FIG. Sectional drawing of the staircase covering material which concerns on embodiment, FIG. 5: is a fragmentary perspective view which shows an example of a mesh body.

  The staircase covering material 1 shown in FIGS. 1 to 3 is a flexible covering material bent in an inverted L shape, and includes a tread surface covering portion 1a that covers the tread surface 20a of the staircase foundation 20 indicated by a virtual line in FIG. The stair nosing covering portion 1b for covering the stair nose 20b of the staircase foundation 20 and the kicking surface covering portion 1c for covering the kicking surface 20c of the stair base 20 are integrally formed. An adhesive layer 2 is formed on the lower surface of the tread surface covering portion 1a of the staircase covering material 1, and the reticulate body 3 is formed on the lower surface of the adhesive layer 2 near the nose covering portion 1b. It is laminated over substantially the entire width of the covering portion 1a. And the release paper 4 which covers this mesh body 3 and the adhesive agent layer 2 is further laminated | stacked on the lower side. Further, on the back surface of the raised surface covering portion 1c of the staircase covering material 1, a raised surface pressure-sensitive adhesive layer 5 is formed over the entire width along the lower edge of the raised surface covering portion 1c. Covered.

  The staircase covering material 1 is formed of a flexible synthetic resin (for example, soft vinyl chloride resin, olefin resin, etc.) or synthetic rubber, and the upper surface of the tread surface covering portion 1a has a size for preventing slipping. A large number of protrusions 1d and 1e are formed and a stair covering portion 1f for reinforcement is formed on the nose covering portion 1b to which stress is repeatedly applied when the stairs are raised and lowered. The staircase covering material 1 of this embodiment itself has a single-layer structure, but it may have a two-layer structure in which a surface layer having a pattern or a pattern and a non-patterned back surface layer (backing layer) are laminated. And it is good also as a three-layer structure which laminated | stacked the intermediate | middle layer and the back layer.

  The adhesive layer 2 is formed by applying an adhesive or an adhesive to the lower surface of the tread surface covering portion 1a of the step covering material 1, or applying a sheet-like or film-like adhesive or adhesive under the tread surface covering portion 1a. It is a layer formed by laminating on the side. This adhesive layer 2 has viscoelasticity and can be flowed because it is necessary to sink the mesh body 3 at the time of stair covering construction or to be pushed out through the opening of the mesh body 3 to the stair base as described later. Is used. As the former pressure-sensitive adhesive, an acrylic, rubber-based, or silicone-based pressure-sensitive adhesive is used, and an acrylic-based pressure-sensitive adhesive is particularly preferably used. The thickness of the adhesive layer 2 formed with these adhesives is preferably in the range of 0.05 to 1 mm, particularly in the case of the adhesive layer 2 formed with an acrylic adhesive. Is optimally about 0.1 mm thick. Moreover, as the latter adhesive, urethane, epoxy, modified silicone, vinyl acetate, acrylic and the like are used, and urethane adhesive is particularly preferably used. The thickness of the adhesive layer 2 formed with these adhesives is preferably in the range of 0.2 to 2.5 mm, and particularly the adhesive layer formed with a urethane-based adhesive. In this case, the thickness is optimally about 1 mm.

  In this embodiment, the adhesive layer 2 is formed on substantially the entire lower surface of the tread surface covering portion 1a of the staircase covering material 1, but only partially on the nose covering portion 1b side of the lower surface of the tread surface covering portion 1a. You may form in. However, in that case, it is necessary to make the formation region of the adhesive layer 2 wider than the layered region of the mesh 3. Further, the adhesive layer 2 may be formed on the lower surface of the tread surface covering portion 1a at a distance of about 3 to 20 mm from the nose covering portion 1b (in other words, the corner portion of the staircase covering material 1).

  The reticulated body 3 exposed and partially laminated on the lower surface of the adhesive layer 2 is peeled off the release paper 4 covering the reticulated body 3 and the stair covering material 1 is stacked on the stair base 20, as will be described later. In addition, the adhesive layer 2 in the laminated region of the mesh body 3 is prevented from being stuck and fixed in contact with the stair base 20, and the positioning work of the stair covering material 1, the repositioning work, In addition to facilitating fine adjustment work and the like, after positioning, when the tread surface covering portion 1a of the stair covering material 1 is pressed from above, the adhesive layer 2 is placed on the stair base 20 side through the opening of the mesh body 3. Or the net body 3 sinks into the adhesive layer 2, and the adhesive layer 2 in the laminated region of the net body 3 and the staircase substrate 20 are brought into contact with each other, whereby the net body 3 of the tread surface covering portion 1a is contacted. It has a function of attaching and fixing the laminated region.

  Although the area | region which laminates this mesh body 3 is not specifically limited, It is preferable to laminate | stack the mesh body 3 over substantially full width in the part near the nose coating part 1b of the lower surface of the adhesive agent layer 2 like this embodiment. . In this way, first, the portion near the nose covering portion 1b of the tread surface covering portion 1a on which the mesh body 3 is laminated is positioned over substantially the entire width, and the tread surface covering portion 1a is moved upward while maintaining this state. Can be attached and fixed on the tread surface covering portion 1a, so that the positioning operation can be easily performed and the positioning can be accurately performed. In addition, it is desirable to laminate | stack the net-like body 3 so that the front end (end on the nose covering part 1b side) may substantially correspond with the front end (end on the nose covering part 1b side) of the adhesive layer 2.

  As described above, when attaching the staircase covering material 1, it is important that the nose 20 a of the staircase foundation 20 and the nose covering portion 1 b of the staircase covering material 1 have an appropriate positional relationship, and an inappropriate position. When the staircase covering material 1 is stuck in relation, the load of a person who goes up and down the stairs is repeatedly applied to the nose covering portion of the staircase covering material, so that the nose covering portion 1b is cracked or the nose covering portion 1b is damaged. Although it becomes a cause of a malfunction, when positioning and adhering and fixing the part near the nose covering part 1b of the tread covering part 1a of the stair covering material 1 over substantially the entire width as described above, Since the staircase covering material 1 can be accurately positioned so that the nose 20b and the staircase covering portion 1b of the staircase covering material 1 have an appropriate positional relationship, such a problem does not occur.

The area of the layered region of the net-like body 3 is not particularly limited, but is preferably 1/10 to 1/2 of the area (total area) of the adhesive layer. The laminated area of the network 3 has a slightly lower adhesive strength than the area of the adhesive layer 2 where the network 3 is not laminated, but the area of the laminated area of the network 3 is adhered as described above. If the area is set to 1/10 to 1/2 of the area of the agent layer 2, a practically sufficient sticking strength can be obtained as the entire region. There is no worry about peeling off. If the area of the layered region of the mesh body 3 is larger than ½ of the area of the adhesive layer 2, the adhesive strength may be insufficient, and the amount of the mesh body 3 used may increase, leading to high costs. There is also. On the other hand, when the area of the layered region of the mesh body 3 is smaller than 1/10 of the area of the adhesive layer 2, the stair covering material 1 is first positioned and the layered region of the mesh body 3 is stuck and fixed. There is a risk that the adhesion strength in the laminated region is insufficient, and the stair covering material 1 is easily displaced, making accurate positioning difficult.
Since the depth dimension (the dimension in the front-rear direction) of the tread surface covering portion 1a of the staircase covering material 1 is usually about 200 to 280 mm, the adhesive layer 2 is formed on substantially the entire lower surface of the tread surface covering portion 1a. If the depth dimension (dimension in the front-rear direction) of the laminated area of the mesh body 3 is set to about 20 to 140 mm, the area of the laminated area of the mesh body 3 is 1/10 to 1 of the area of the adhesive layer 2. / 2 or so.

  The reticulated body 3 is made of a synthetic resin reticulated sheet (including a reticulated film) in which a large number of openings are formed in a fixed array pattern, or a reticulated reticulated fiber, organic fiber, inorganic fiber, or other fiber (mesh yarn). A suitable net is preferably used. As the material resin for the former net-like sheet, ester resins such as vinyl chloride resin, acrylic resin and polyethylene terephthalate, and olefin resins such as polyethylene and polypropylene are suitable, and polypropylene is particularly preferably used.

  The mesh body 3 of the present embodiment is a polypropylene mesh sheet formed by arranging square openings 3a vertically and horizontally as shown in FIG. 5, and the length of one side of the opening 3a is about 2 to 50 mm (preferably Is about 5 to 10 mm), the distance between the openings 3a and 3a (that is, the width of the mesh portion corresponding to the non-opening region) is about 1 to 50 mm (preferably about 2 to 10 mm), and the thickness of the sheet is It is about 0.3 to 3 mm (preferably about 0.5 to 1 mm). The mesh sheet 3 has a different area ratio (aperture ratio) of the openings 3a in the mesh sheet 3 depending on the length of one side of the openings 3a and the mutual interval between the openings 3a. In this embodiment, the mesh sheet 3 conforms to JIS A 5536. Based on the 90 ° peel test, the reticulated sheet 3 and the sticking having an opening area ratio such that the sticking strength (peeling strength) falls within the range of 10 to 70 N / 25 mm, preferably 20 to 40 N / 25 mm. The kind of the adhesive agent for the agent layer 2 is selected so that it can be reliably attached to the staircase substrate 20 so as not to peel off the reticulated body 3 laminated region of the staircase covering material 1.

  The shape of the opening 3a of the mesh body (mesh sheet) 3 is not limited to a square, but is a regular polygon such as a regular triangle, a regular hexagon, a regular octagon, an isosceles right triangle, a rectangle, a rhombus, a circle, or an ellipse. Various shapes such as shapes can be used. Further, the arrangement pattern of the openings 3a is not limited to the vertical and horizontal arrangement patterns, and various arrangement patterns such as a diagonal arrangement and a staggered arrangement pattern can be used.

  On the other hand, when the net 3 is a net made of synthetic resin fibers or the like, the net of the fibers (intersection of the net yarn) is knotted by heat-sealing or binding, and the intersection of the fibers is knotted. You may use a net that is not. Such a net has a side length of about 2 to 50 mm (preferably about 5 to 10 mm) and a fiber thickness of about 0.2 to 2 mm (preferably 0.3 to 1 mm). Some are suitable. The shape of the opening (mesh) can be a desired shape such as a square, a rectangle, a regular triangle, a diamond, or a regular hexagon.

  Even when the above-described net is used as the net 3, as described above, the adhesion strength (peel strength) in the 90 ° peel test based on JIS A 5536 is in the range of 10 to 70 N / 25 mm, preferably 20 to 40 N / 25 mm. It is important to select the opening ratio of the net and the type of the adhesive for the adhesive layer 2 so as to fit in the interior.

  The release paper 4 that covers the net 3 and the adhesive layer 2 is not contaminated or wetted until the adhesive layer 4 contacts and sticks to the tread surface 20a of the stair base 20 so that the adhesive force does not decrease. In addition, the adhesive layer 2 covers the adhesive layer 2 so that the adhesive layer 2 does not interfere with the covering and pasting work by adhering to other objects. It consists of a thin sheet or film. The material is arbitrary, For example, what peeled the surface of paper, a synthetic resin sheet, or a film, what formed the synthetic resin which has peelability in the shape of a thin sheet or film, etc. are used.

  In this embodiment, as shown in FIGS. 1 to 3, a single release paper 4 is configured to cover both the mesh 3 and the adhesive layer 2 other than the mesh laminate region. As shown in FIG. 4, two release papers 4A and 4B are used, one release paper 4A covers the net 3 and the other release paper 4B covers the adhesive layer 2 other than the net laminate region. You may comprise as follows.

  When covering both the mesh body 3 and the adhesive layer 2 with one sheet of release paper 4 as in this embodiment, as shown in FIG. 2, the rear end of the mesh body 3 (opposite to the nose covering portion 1b). It is desirable to form a perforation line 6 </ b> A in the lateral direction on the release paper 4 over the entire width along the edge of the release paper 4 so that the release paper 4 can be divided at a portion corresponding to the laminated region of the mesh 3. In this way, the part 3 of the release paper 4 corresponding to the laminated area of the mesh body 3 can be peeled and removed while being divided along the perforation line 6A, so that the mesh body 3 can be easily exposed. improves. Further, as shown in FIG. 3, when a plurality of perforation lines 6B in the vertical direction (depth direction) are formed on the release paper 4 with an interval of about 2 to 10 cm, the release paper 4 is formed on the perforation lines 6A and 6B. Since it can be easily peeled and removed while being finely divided, the workability is further improved.

  Moreover, when separately covering the mesh body 3 and the adhesive layer 2 using two release papers 4A and 4B, as shown in FIG. 4, either one before or after the release paper 4A covering the mesh body 3 is used. By extending the edge and bending downward, the peeling protrusion 7A is formed, and the front edge (edge on the net side) of the release paper 4B covering the adhesive layer 2 is extended and bent downward. Thus, it is desirable to form the peeling protrusion 7B. Forming such peeling protrusions 7A and 7B has an advantage that workability is improved because the peeling sheets 4A and 4B can be easily peeled and removed by picking the protrusions 7A and 7B with a finger. The release paper 4A covering the mesh 3 is peeled off before the stair covering material 1 is stacked on the stair base 20, so that the peeling protrusion 7A of the release paper 4A may be omitted.

  The kick-up surface pressure-sensitive adhesive layer 5 formed on the back surface of the covering portion 1c along the lower edge of the step-up covering material 1 of the staircase covering material 1 is peeled off from the kick-up surface 20c of the stair base 20 by the kick-up surface covering portion 1c. In order to prevent the stair covering material 1 from rolling up, the kick covering portion 1c is adhered and fixed to the kicking surface 20c of the stair base 20, and for example, an acrylic pressure-sensitive adhesive is applied to both surfaces of a thin strip-shaped resin foam sheet. A coated double-sided adhesive tape having a three-layer structure or a single-layer butyl rubber sheet having a strip shape is preferably used. As the release paper 40 covering the kick-up surface pressure-sensitive adhesive layer 5, a strip-like release paper made of the same material as the release paper 4 described above is used.

  Although not shown, a foam layer may be formed between the staircase covering material 1 and the adhesive layer 2, and when the foamed layer is formed in this way, the staircase covering material 1 is When the layered portion of the mesh body 3 is pressed from above on the stair base 20, the mesh body 3 sinks into the adhesive layer 2 while compressively deforming the foamed layer, and the adhesive agent is opened from the opening of the mesh body 3. There is an advantage that the layer 2 is easily pushed out toward the staircase substrate 20 side. As the foam layer, for example, a foam sheet having a thickness of about 1 to 5 mm obtained by continuously or independently foaming a synthetic resin is preferably used.

  Moreover, in this embodiment, although the single-layer adhesive agent layer 2 is formed in the lower surface of the tread surface covering part 1a of the staircase covering material 1, it adheres to both surfaces of a resin foam sheet as the adhesive agent layer 2. You may use the double-sided adhesive sheet of the 3 layer structure which apply | coated the agent, the double-sided adhesive sheet of the 3 layer structure which laminated | stacked the sheet-like adhesive agent on both surfaces of the resin foam sheet, etc. When such a double-sided adhesive sheet is provided on the lower surface of the tread surface covering portion 1a, when the staircase covering material 1 is superimposed on the staircase foundation 20 and the layered portion of the mesh body 3 is pressed from above, the same as described above. The net body 3 is sunk while compressing and deforming the resin foam sheet of the double-sided adhesive sheet, so that the adhesive is easily pushed out from the opening of the net body 3 to the staircase substrate 20 side.

  Next, the staircase covering method of the present invention using the staircase covering material will be described with reference to FIGS.

  First, while separating the release paper 4 of the staircase covering material 1 along the perforation line 6A, the part of the release paper corresponding to the laminated region of the mesh 3 is peeled and removed as shown in FIG.

  Next, as shown in FIG. 7, the stair covering material 1 is overlapped on the stair base material 20, and the stair covering material 1 is arranged so that the nose covering portion 1 b of the stair covering material 1 and the stair nose 20 b of the stair base material 20 are in an appropriate positional relationship. Perform positioning. In the state where the staircase covering material 1 is overlaid on the staircase base 20, the mesh 3 and the release paper 4 come into contact with the tread surface 20a of the staircase base 20 as shown in FIG. Since it does not contact the surface 20a, it is possible to easily perform the positioning operation while moving the staircase covering material 1, and of course, it is possible to easily perform the repositioning operation and the fine adjustment operation of the position.

  Before the stair covering material 1 is stacked on the stair base 20, a filler 8 is attached in advance to the back surface of the nose covering portion 1b of the stair covering material 1, and the stair covering material 1 is attached to the stair as shown in FIG. When superposed on the base 20, the filler 8 is filled between the nose covering portion 1 b of the staircase covering material 1 and the nose 20 b of the staircase base 20. The purpose of the filler 8 is to fill a gap caused by a small positional deviation at the time of attaching the staircase covering material 1 or the thickness of the kick-up surface adhesive material layer 5 or to fill a missing portion of the step nose 20b of the staircase foundation 20. For example, a one-component or two-component urethane-based, two-component epoxy-based, one-component modified silicone-based filler or the like is preferably used.

  When the positioning of the staircase covering material 1 is finished, as shown in FIG. 8, the laminated region of the mesh body 3 of the tread surface covering portion 1 a of the staircase covering material 1 is pressed from above toward the tread surface 20 a of the staircase foundation 20. . Then, the adhesive layer 2 is partially pushed out to the staircase base 20 side through the opening of the net-like body 3, or the net-like body 3 sinks into the adhesive layer 2, and the adhesive layer 2 and the staircase base 20 The tread surface 20a contacts and the tread surface covering portion 1a of the staircase covering material 1 is adhered and fixed to the tread surface 20a of the staircase foundation 20 in the layered region of the mesh body 3. As described above, when the region near the nose covering portion 1b where the mesh body 3 of the tread surface covering portion 1a is laminated is positioned and fixed over substantially the entire width, the entire positioning of the staircase covering material 1 is easily and accurately performed. Can be done.

  When the pasting of the mesh layered region of the tread surface covering portion 1a of the staircase covering material 1 is completed, the release paper 40 covering the raised surface adhesive layer 5 on the back surface of the raised surface covering portion 1c is peeled and removed, and FIG.
