Description

  The present invention relates to a staircase covering structure and a covering method thereof that can improve the safety and design of staircases, the sound insulation and slipperiness during ascending / descending, and maintain the performance for a long period of time.

Conventionally, when covering a staircase with a staircase covering material, it is necessary to firmly fix it on the staircase base from the viewpoint of ensuring the safety of pedestrians. The method of fixing was taken.
Such a curing type adhesive takes time until the curing progresses to a certain degree and the adhesive strength is developed. Therefore, before the adhesive strength is developed, the top of the staircase covering material coated on the staircase is covered. When walking, there was a problem that the staircase covering material was displaced from an appropriate position or peeled off.

Moreover, in the staircase covering structure in which the staircase covering material that covers the kicking surface from the stepped surface of the staircase is bonded to the staircase bottom surface, it is approximately 90 ° downward from the stepping surface of the staircase base to the lower side kicking up. Using a synthetic resin stair covering material that is bent and bent upward at approximately 90 ° toward the upper kick-up, the upper stair covering material is directed downward on the upward rising surface covering portion of the lower stair covering material. In many cases, the lifted surface covering part is overlapped and joined, but it is necessary to adjust the bent part according to the width in the depth direction of the stepping surface of the staircase foundation. It is necessary to form a bent portion at an appropriate position on the kick-up surface covering portion.
In such a case, as a characteristic of the step covering material made of synthetic resin, the bent portion tends to return to the state before the bending, so before the adhesive strength of the adhesive is expressed, the vicinity of the bent portion is There is a problem that the tread surface covering portion and the kick-up covering portion are displaced due to the floating from the stair base.

On the other hand, the bent part from the step surface of the staircase to the lower kick-up surface is a part that serves as a reference for the covering operation, so it is often bent in advance, but the staircase foundation formed at various angles ( It is bent at an angle smaller than 90 ° so that it can correspond to the corner angle of the tread surface and the kick-up).
For example, when a staircase base having a corner angle of 90 ° is coated using such a staircase covering material, the downwardly raised surface covering portion of the upper staircase covering material is intended to return to an angle smaller than 90 ° that has been bent in advance. For this reason, there is a problem that the upper stepped surface covering material of the lower step peels off from the staircase base surface together with the upwardly raised kick surface covering portion or shifts from an appropriate position.
In order to cope with this problem, the adhesive force by the initial adhesive is improved by applying an adhesive to the stair base surface and covering the step covering material after taking an open time of about 30 minutes. However, in this case, there is a problem that a waiting time for the work occurs, the work efficiency is lowered, and the closed time during the work becomes long.

Therefore, the applicant of the present application firstly overlapped the staircase floor made of synthetic resin over the stepped surface of the staircase and the kicked up connected to the stepped surface, and the overlapping part of the floorboard, the stepped surface and the raised surface A staircase structure that is joined by a belt-like adhesive layer provided across the surface and a butyl rubber-based pressure-sensitive adhesive layer provided throughout the portion where the adhesive layer is not disposed (see Patent Document 1) ) And a staircase structure (see Patent Document 2) in which a floor sheet made of a synthetic resin having a soft foam layer formed on the back surface is joined with a sheet-like pressure-sensitive adhesive on a staircase surface having an uneven tread surface Proposed.

  Embodiments of the staircase covering structure and the covering method according to the present invention will be described below.

FIG. 1 shows an embodiment of a staircase covering structure according to the present invention.
This staircase covering structure is obtained by bending the staircase covering material 2 upward and downward along the raised surface 14 at the corner corner portion 12 and the nose corner portion 11 of the stepping surface 13 of the foundation of the staircase 1. 1 is fixed to the tread base 13 and the kicking surface 14 via the adhesive tapes 3a and 3b and the adhesive layer 4, and the upper step covering material 2 is disposed on the upper kicking surface covering portion 21 on the upper step. The staircase covering material 2 is a staircase covering structure in which a downwardly raised kick surface covering portion 22 is fixed via a second adhesive tape 30, and the first adhesive tapes 3 a and 3 b are stepped on the base of the staircase 1. The base of the staircase 1 including the periphery of the first adhesive tapes 3a and 3b, which is disposed in the width direction of the staircase at the back of the face 13 on the corner corner portion 12 side and at the top of the nose corner portion 11 side of the kick-up surface 14 Tread surface 13 and kick-up surface 14 Adhesive layer 4 in which is formed.

  Here, the “back part of the corner 13 on the side of the tread 13 on the base of the staircase 1” on which the first adhesive tape 3a is disposed is the corner corner 12 on the corner 13 of the base 13 on the base of the staircase 1. The distance from the center is preferably 5 to 100 mm, preferably 10 to 60 mm (region Ara indicated by a dotted line in FIG. 2), and the first adhesive tape 3b is disposed "(under the ground of the staircase 1)" The “upper portion of the kicking surface 14 on the nose corner portion 11 side” means a portion where the distance from the nosing corner portion 11 of the kicking surface 14 of the base of the stairs 1 is between 5 and 75 mm, preferably between 10 and 60 mm. (Area Arb indicated by a dotted line in FIG. 2) is meant.

  By the way, the covering structure of the staircase is such that the first adhesive tapes 3a and 3b are disposed on the back of the stepping surface 13 on the base of the staircase 1 on the inner corner corner 12 side and on the upper side of the kicking surface 14 on the nose corner portion 11 side. Adhesive is applied in the width direction of the staircase 1 and an adhesive is applied to the base tread surface 13 and the kick-up surface 14 of the staircase 1 including the periphery of the first adhesive tapes 3a and 3b to form the adhesive layer 4. The staircase covering material 2 is sequentially attached and fixed to the base of the staircase 1 from the bottom to the top of the staircase 1 through the first adhesive tapes 3a and 3b and the adhesive layer 4, and the lower staircase cover is fixed. It can be constructed by adhering and fixing a downwardly raised kick surface covering portion 22 of the upper staircase covering material 2 via a second adhesive tape 30 on the upwardly raised kick surface covering portion 21 of the material 2. .

More specifically, the staircase covering material 2 is attached to the base of the staircase 1 in the following order.
(1) The first adhesive tapes 3a and 3b with release paper are placed in the width direction of the stairs 1 at the back of the tread surface 13 on the corner corner portion 12 side and at the top of the nose corner portion 11 side of the kicking surface 14 Adhere.
(2) The adhesive layer 4 is formed by applying an adhesive in a comb pattern on the entire surface of the base of the staircase 1 including the periphery of the first adhesive tapes 3a and 3b.
In this case, the adhesive is applied so that the thickness of the adhesive layer 4 in the state covered with the staircase covering material 2 is substantially the same as the thickness of the first pressure-sensitive adhesive tapes 3a and 3b.
(3) Peel off the release paper of the first adhesive tapes 3a and 3b. At this time, the adhesive adhered on the release paper of the first adhesive tapes 3a and 3b can be removed at the same time.
(4) The staircase covering material 2 is sequentially applied from the lower step to the upper step side of the staircase 1 from the tread surface 13 of the staircase 1 of the staircase covering material 2, which is a reference part at the time of the covering operation, to the lower kicking surface 14 Using the bent portion as a reference, the tread surface 13 and the upper kick-up surface 14 are attached and fixed to the base of the stairs 1 in this order.
In this case, the staircase covering material 2 is bent along the corner corner portion 12. At this time, if the bent portion is pressed strongly on the tread surface 13 so as to mold the bent portion, the corner corner portion of the tread surface 13 is formed. Since the 1st adhesive tape 3a stuck to the back part by the side of 12 and the foundation | substrate of the staircase 1, and the staircase covering material 2 are each crimped | bonded strongly, adhesive force can be increased.
In addition, when the length of the upward kicking surface covering portion 21 of the staircase covering material 2 exceeds the height of the kicking up, the portion is cut and removed with a cutter knife or the like.
Further, the release paper of the second adhesive tape 30 is peeled off, and the downwardly raised surface covering portion 22 of the upper stairs covering material 2 is placed on the upwardly raised surface covering portion 21 of the lower stairs covering material 2 in the second manner. The adhesive tape 30 is attached and fixed.
Further, as shown in FIG. 1, gaps 41, 42 formed between the staircase covering material 2 and the nose corner portion 11 or the corner corner portion 12, and a triangle at the tip of the downwardly raised kick surface covering portion 22 of the staircase covering material 2. As the reinforcing portion 43, another optimal sealing agent (caulking agent) having appropriate filling properties and sealing properties can be used.

  In this case, the base of the staircase 1 is not particularly limited, such as concrete, steel plate, or wood.

Stairs covering material 2, is not particularly limited, are use vinyl chloride resin, made of thermoplastic resin such as polyolefin resin (e.g., Taki step 4W (trade name, manufactured by Takiron Co., Ltd.)) be able to.
In this case, the staircase covering material 2 is a single layer, laminated and integrated, and further laminated with a glass fiber layer having dimensional stability and a reinforcing effect between the surface layer and the back surface layer, the backmost surface A laminate of synthetic resin non-woven fabric layers for improving the adhesion with the base and preventing the stair covering material 2 from swelling due to aeration and gas holding action can be appropriately used.
Further, the staircase covering material 2 is formed at various angles with bent portions from the tread surface 13 of the staircase 1 to the lower kick-up surface 14 of the staircase covering material 2 which is a reference part at the time of covering work. In order to be able to cope with the ground of the staircase 1 (the corner angle between the tread surface and the kick-up surface), it is possible to use one in which the angle between the tread surface covering portion and the kick-up covering portion is bent at an angle smaller than 90 °. . In addition to those bent at an angle smaller than 90 ° as described above, those bent at an angle larger than 90 ° and those bent at 90 ° should be used. Needless to say, you can.
In addition, the stair covering material 2 is thickened at the bent portion from the tread surface 13 of the stair 1 to the lower kicking surface 14 of the stair covering material 2 in order to maintain safety during elevation for a long period of time. In addition, one having an anti-slip convex pattern 23 or the like can be used.

The first pressure-sensitive adhesive tapes 3a, 3b and the second pressure-sensitive adhesive tape 30 can use arbitrary pressure-sensitive adhesive tapes, but have high adhesive strength, little deterioration due to moisture and heat, and maintain adhesiveness for a long time. Can be made of acrylic resin-based adhesive and butyl rubber-based adhesive, or non-woven fabric or woven fabric made of foamed synthetic resin, synthetic fiber or glass fiber as the core layer, and acrylic resin-based adhesive or butyl rubber-based adhesive on both sides What applied the agent (it does not exclude other adhesive tapes) can be used suitably.
In this case, the first pressure-sensitive adhesive tapes 3a and 3b are tape-like products having a width of about 10 to 50 mm and a thickness of about 0.1 to 2.0 mm, and preferably a thickness of about 0.2 to 1.0 mm. In addition, those provided with release paper can be suitably used.
The second pressure-sensitive adhesive tape 30 can be a tape-like material having a width of about 10 to 50 mm and a thickness of about 0.5 to 3.0 mm, preferably about 1.0 to 2.5 mm.
Moreover, the first adhesive tapes 3a and 3b are not limited to one each, and a plurality of the first adhesive tapes 3a and 3b may be attached in parallel with a predetermined interval as necessary.

  Further, the adhesive of the adhesive layer 4 is not particularly limited, but curable adhesive such as one-component (moisture curing) type urethane adhesive, two-component type urethane adhesive, two-component type epoxy adhesive, etc. An agent, various emulsion adhesives, etc. can be used conveniently. Here, solvent-free curable adhesives such as urethane adhesives and epoxy adhesives are very slow in developing adhesive strength, but these adhesives with a slow rate of adhesive strength should be used without any problem. Therefore, the present invention is useful.

Unless there are special circumstances, the adhesive layer 4 is formed on the entire surface of the tread 13 and the kick-up surface 14 of the base of the staircase 1 including the periphery of the first adhesive tapes 3a and 3b.
In this case, it is preferable to apply the adhesive so that the thickness of the adhesive layer 4 in the state covered with the staircase covering material 2 is approximately the same as the thickness of the pressure-sensitive adhesive tapes 3a and 3b. For this reason, the thickness of the first pressure-sensitive adhesive tapes 3a and 3b is smaller than the comb height of 1.0 to 3.0 mm when the adhesive is applied (by coating with the staircase covering material 2, It is preferable that the comb height of the agent is compressed). By using the adhesive tapes 3a and 3b having such a thickness, the staircase covering material 2 does not rise or dent at the position of the adhesive tapes 3a and 3b. Don't be.

The adhesive layer 4 is preferably formed on the entire circumference of the first pressure-sensitive adhesive tapes 3a and 3b. In particular, as shown in FIG. 2, around the first pressure-sensitive adhesive tapes 3a and 3b. The dimensions La and Lb of the base of the staircase 1 of the adhesive layer 4 to be formed are set to 5 to 50 mm, preferably 10 to 30 mm.
Thereby, it is possible to reliably supplement the adhesive force of the adhesive until the adhesive strength is developed, and to form on the base tread surface 13 and the kick-up surface 14 of the staircase 1 including the periphery of the first adhesive tapes 3a and 3b. By the adhesive layer 4 that has been made, the adhesive force between the stair covering material 2 and the base of the stair 1 over a long period of time in a poor environment can be ensured more reliably.

  Moreover, the adhesive can change the material to use suitably according to a use site | part etc., for example, as shown in FIG. 1, the staircase covering material 2, and the nose corner part 11 and the entering corner corner part 12 are used. For the gaps 41 and 42 formed between them and the triangular reinforcing portion 43 at the tip of the downwardly raised surface covering portion 22 of the staircase covering material 2, instead of an adhesive, another type of optimum sealing having a filling property and a sealing property is appropriately provided. An agent (caulking agent) can be used.

Table 1 shows the results of an evaluation test of workability and the floating / displacement of the stair covering material 2 depending on the part of the first adhesive tape 3a, 3b attached to the base of the stair 1.
Conditions for evaluation test: Underground for staircase 1: Made of concrete, staircase covering material 2: made of thermoplastic resin (Takistep 4W (trade name, manufactured by Takiron Co., Ltd.))
First adhesive tape 3a, 3b: 25 mm wide and 0.3 mm thick adhesive tape with acrylic resin adhesive applied to both surfaces of synthetic fiber woven fabric as a core material Second adhesive tape 30: foamed synthetic resin 22 mm wide and 2.0 mm thick adhesive tape / adhesive layer 4: one-component (moisture curing) type urethane adhesive / working condition: temperature 5 ℃, Open time 1-2 minutes ・ Curing conditions: Air temperature 5 ℃, Curing time 2 hours ・ Evaluation of workability: ○ Good (suitable), △ Somewhat bad (somewhat unsuitable), × Bad (unsuitable)
・ Evaluation of floating / displacement: ○ None (appropriate), △ Slightly (slightly inappropriate), × × (unsuitable)

As is apparent from Table 1, when the first adhesive tape 3a is attached to the back of the tread 13 on the base of the staircase 1, the staircase covering material 2 is adjusted while the staircase covering material 2 is being adjusted. 2 does not contact and adhere to the first adhesive tape 3a, the position can be adjusted easily, and the nose corner portion 11 is not displaced.
On the other hand, if the attachment position of the 1st adhesive tape 3a is made in front of the tread 13 of the base of the staircase 1 (near the nose corner part 11) or the center part, the position of the staircase covering material 2 is adjusted. While the staircase covering material 2 was in contact with and adhered to the first adhesive tape 3a, it was difficult to adjust the position, and the staircase corner portion 11 was displaced after curing.
On the other hand, when the attachment position of the first adhesive tape 3b is set above the kick-up surface 14 of the base of the staircase 1, when the staircase covering material 2 is entered and bent along the corner corner portion 12, the staircase covering material 2 is The adhesive tape 3b is not contacted and adhered, the position adjustment is easy, the nose corner portion 11 does not float, and the upper end portion of the kick-up surface does not float or shift.
On the other hand, when the attachment position of the first adhesive tape 3b is set to the center part or the lower part of the kick-up surface 14 of the foundation of the staircase 1, when the staircase covering material 2 is entered and bent to the corner corner part 12, Since the staircase covering material 2 contacts and adheres to the first adhesive tape 3b, it is difficult to adjust the position, and the nose corner portion 11 is lifted, and the upper end of the kicked surface is also lifted.
Further, the staircase covering material 2 has a property of becoming hard at a low temperature, and the force (repulsive force) at which the bent portion of the staircase covering material 2 floats at the nose corner portion 11 and the entering corner corner portion 12 is increased. However, by sticking the first adhesive tapes 3a and 3b on the back of the tread 13 on the base of the staircase 1 and on the top of the kick-up surface 14 on the base of the staircase 1, the adhesive tape 3a, 3b is displaced even at a low temperature (5 ° C.). There was no lift.

If the first adhesive tape 3a is attached in contact with the innermost corner portion 12 of the bottom tread 13 of the stairs 1, that is, the innermost corner portion 12 of the bottom tread 13 of the stairs 1, When the staircase covering material 2 is inserted and crimped to the corner corner portion 12, the adhesive applied to the kick-up surface 14 of the base of the staircase 1 flows onto the first adhesive tape 3a, and the effect of the first adhesive tape 3a is achieved. The staircase covering material 2 is lifted during long-term use because it is not effectively used or the corner portion 12 and the staircase covering material 2 are fixed with an adhesive tape whose long-term durability is inferior to that of an adhesive. There are concerns.
In addition, when any one of the first adhesive tapes 3a and 3b was omitted, the staircase covering material 2 on the surface where the first adhesive tapes 3a and 3b were omitted was displaced.

This step covering structure and the covering method have the following effects.
(1) Adhering the first adhesive tapes 3a and 3b by sticking them in the width direction of the staircase 1 on the back of the tread 13 of the base of the staircase 1 and the top of the kicking surface 14 of the base of the staircase 1 Compensates the adhesive strength of the adhesive until strength is developed, and can absorb the force (repulsive force) of the folded portion of the staircase covering material 2 at the corner corner portion 12 and the force that shifts due to human walking. Thus, the open time can be shortened or omitted, the work efficiency can be improved, and the closed time during the work can be shortened, and the ground of the staircase 1 including the periphery of the first adhesive tapes 3a and 3b can be reduced. The adhesive layer 4 formed on the tread surface 13 and the kick-up surface 14 can secure the adhesive force between the stair covering material 2 and the ground of the stair 1 for a long time in a poor environment.
(2) The first adhesive tapes 3a and 3b are covered in the width direction of the stairs 1 by sticking the first adhesive tapes 3a and 3b on the back of the tread surface 13 of the stairs 1 and the upper part of the kicking surface 14 of the stairs 1 In order to adjust the position of the staircase covering material 2 during the covering operation, the vicinity of the bent portion from the tread surface 13 of the staircase 1 to the lower kick-up surface 14 as a reference during the work is not restrained. It is possible to prevent problems.
(3) By fixing the downwardly raised surface covering portion 22 of the upper stairs covering material 2 on the upwardly raised surface covering portion 21 of the lower stairs covering material 2 via the second adhesive tape 30, It can compensate the adhesive strength of the adhesive until the adhesive strength is developed, and can absorb the force (repulsive force) of the folded portion of the staircase covering material 2 at the nose corner portion 11 and the force that shifts due to human walking. As a result, it is possible to shorten or omit the open time until coating with the staircase covering material 2.
(4) The adhesive layer 4 is formed on the entire circumference of the first pressure-sensitive adhesive tapes 3a and 3b, and in particular, the step 1 of the adhesive layer 4 formed around the first pressure-sensitive adhesive tapes 3a and 3b. By setting the dimension in the width direction of the base to 5 to 50 mm, it is possible to reliably supplement the adhesive strength of the adhesive until the adhesive strength is developed, and the staircase 1 including the periphery of the first adhesive tapes 3a and 3b. By the adhesive layer 4 formed on the tread 13 and the kick-up surface 14 of the base, it is possible to more reliably secure the adhesive force between the stair covering material 2 and the base of the stair 1 over a long period of time in a poor environment. .

  As mentioned above, although the covering structure of the staircase and the covering method thereof according to the present invention have been described based on the embodiment, the present invention is not limited to the configuration described in the above embodiment, and does not depart from the spirit thereof. The configuration can be changed as appropriate within the range.

  The staircase covering structure and the covering method according to the present invention enable safety and design of staircases so as not to hinder the position adjustment of staircase covering materials during covering work while enabling shortening and omission of the open time. Therefore, it can be used for covering the stairs of public facilities and public facilities because it can maintain the performance over a long period of time.
