Description

  The present invention relates to a flooring construction method, and in particular, relates to a construction method when a rectangular flooring is directly pasted to a floor base to form a flooring.

  It is known that a large number of rectangular flooring materials having a size of 300 mm × 1800 mm are directly pasted on an under floor using an adhesive to form a flooring. Usually, an adhesive such as an epoxy resin or a cross-linked vinyl acetate resin is used as the adhesive, and after the adhesive is applied to the floor base surface or the back surface of the floor material, the floor material is placed on the floor base. Before the adhesive is cured, that is, before sufficient adhesive force is obtained, the floor material is positioned on a predetermined position while sliding on the floor base, and the actual part formed around the floor material 4 is used. Nailing and temporarily fixing in place, wait for the adhesive to cure. If the temporary fixing by nailing is omitted, it is not preferable because a positional shift occurs before the adhesive is cured.

  When using a solvent-type adhesive that has strong adhesive strength and hardens early, temporary fixing such as nailing may be omitted, but harmful substances may volatilize and positioning may be performed precisely. It becomes difficult.

  There has been proposed a flooring construction method in which a flooring material is fixed to a floor base using a double-sided adhesive tape without using an adhesive (see Patent Documents 1 and 2, etc.). As the double-sided pressure-sensitive adhesive tape, one having a pressure-sensitive adhesive layer made of an acrylic pressure-sensitive adhesive on both surfaces of a tape base material such as foamed polyethylene is suitably used.

  The flooring construction method that uses double-sided adhesive tape to fix the flooring to the floor floor allows the flooring with the release paper peeled off to slide on the floor floor, making it easy to position the flooring. By pressing from above after positioning, there is an advantage that the flooring can be fixed at a required position by the adhesive force of the double-sided adhesive tape. However, in order to obtain the adhesive force required to fix the flooring to the floor base surface with only the adhesive strength of the double-sided adhesive tape, it is necessary to apply the double-sided adhesive tape to a considerable area on the back of the flooring. This increases the cost and requires a lot of labor for the work of peeling the release paper at the construction site, the work of disposing the peeled release paper, and the like.

  The present invention has been made in view of the above circumstances, and it is possible to directly apply a flooring material to a floor base at a low cost and with a small work amount while taking advantage of the double-sided adhesive tape. An object of the present invention is to provide a construction method for flooring.

  The present invention is a construction method for directly attaching a rectangular flooring material to a floor base to make a flooring, and carrying a flooring material in which a double-sided adhesive tape is bonded to a part of the back surface to a construction site, , Peel off the release paper attached to the adhesive layer of the double-sided adhesive tape, apply adhesive to the back of the flooring, and place it on the floor base and slide it into place. , After positioning, pressing the floor material from above to the floor substrate, and temporarily fixing the floor material to the floor substrate by the adhesive force of the adhesive of the double-sided adhesive tape is characterized by sequentially performing a plurality of floor materials .

  In the above construction method, the temporary fixing of the floor material to the floor base is performed by the adhesive force of the double-sided adhesive tape, and the main fixing is performed by the adhesive applied to the back surface of the floor material. Therefore, the area of the double-sided pressure-sensitive adhesive tape to be affixed to a part of the back surface may be an area necessary for temporary fixing, and the amount used is very small. As a result, the cost associated with the double-sided adhesive tape is reduced, and the work for peeling the release paper and the work for disposing of the peeled release paper are reduced, and the work efficiency is improved.

  In the state where the release paper is peeled off from the double-sided pressure-sensitive adhesive tape, the flooring can slide on the floor base, so that the positioning of the flooring can be performed reliably. By pressing from above after positioning, the adhesive force of the double-sided adhesive tape is effectively exerted, and the flooring is temporarily fixed to the floor base. In this state, similarly, the next floor material is sequentially arranged, positioned, and temporarily fixed on the floor base. Since the flooring material is temporarily fixed in sequence, there will be no misalignment during construction. All the flooring materials are temporarily fixed, and the adhesive applied to the back surface of the flooring material is allowed to harden. Thereby, desired flooring construction is completed.

  As described above, the area of the double-sided pressure-sensitive adhesive tape to be attached to the back surface is not particularly limited as long as the adhesive force necessary for temporary fixing is obtained, and the attachment position and area are not particularly limited, but it is effective with less adhesive force. Since it is possible to obtain a temporary fixing force, it is effective to apply it in parallel to the short side direction of the rectangular flooring, and to apply it in parallel to the short side direction at two locations near both ends in the long side direction. It is particularly effective.

  The double-sided pressure-sensitive adhesive tape to be used may be a conventionally known one, for example, one having a pressure-sensitive adhesive layer that is an acrylic pressure-sensitive adhesive on both surfaces of a foamed polyethylene tape base material. Other examples of the tape base material include a foamed polyurethane tape base material and a foamed polypropylene tape base material.

  As the rectangular flooring to be used, those conventionally known can be used as they are. For example, what laminated | stacked the appropriate surface decoration material like a veneer on the surface side of the plywood as a base material or a wood fiber board is mentioned. A large number of concave grooves may be formed on the back side of the base material to cope with unevenness of the floor base. It may be a floor material in which a buffer material is laminated on the back surface of the base material to improve sound insulation performance. In the floor material of this form, a double-sided adhesive tape is bonded to an appropriate position on the back surface of the laminated cushioning material.

  ADVANTAGE OF THE INVENTION According to this invention, a floor material can be directly affixed on a floor base | substrate at low cost and a small work amount, utilizing the advantage which a double-sided adhesive tape has.

  Hereinafter, the present invention will be described based on embodiments with reference to the drawings. FIG. 1 is a back view of an example of a rectangular flooring used in the flooring construction method according to the present invention, FIG. 2 is a side view thereof, and FIG. 3 shows a state in which release paper is removed from the flooring. 4a and 4b show a work procedure when the floor material is stuck on the floor base.

  In the illustrated example, the flooring 1 has a rectangular shape, the total length is about 1800 mm, the width is about 300 mm, and the thickness is about 12 mm. The flooring 1 is composed of a wood part 2 and a buffer material 3, and in this example, the wood part 2 is a plywood having a thickness of about 9 mm, but may be a wood fiber board such as MDF. A surface decorative material 4 such as a veneer is laminated on the front surface side of the wood part 2, and a buffer material 3 having a thickness of about 3 mm is laminated on the back surface side. A material such as a soft foamed olefin-based sheet or a synthetic resin-based nonwoven fabric sheet is used for the buffer material 3. Actual processing 5 is performed around the wood portion 2.

  In the vicinity of both ends in the longitudinal direction of the flooring 1, a double-sided adhesive tape 10 is bonded in parallel with the short sides 6 and 6. The double-sided pressure-sensitive adhesive tape 10 has a width of about 10 to 30 mm. For example, the pressure-sensitive adhesive layer 11 made of an aliicle-type pressure-sensitive adhesive is formed on both surfaces of a foamed polyurethane sheet that is a tape base material. One adhesive layer adheres to the back surface of the cushioning material 3 laminated on the back surface of the flooring 1 (wood part 2), and the release paper 12 is attached to the other adhesive layer 11.

  The flooring 1 in this state is carried into the construction site. As shown in FIG. 3, the worker performing the flooring construction removes the release paper 12 attached to the adhesive layer 11 of the double-sided pressure-sensitive adhesive tape 10 from the floor material 1, and removes the back surface of the floor material 1 (this In this case, an adhesive 13 such as an epoxy resin adhesive or a rubber latex resin adhesive is applied to the back surface of the buffer material 3. Application of the adhesive 13 may be performed on the entire back surface of the floor material except for the place of the double-sided pressure-sensitive adhesive tape 10, and may be performed only on a part of the back surface when a necessary adhesive force is obtained.

  The release paper 12 is removed, and the operator places the flooring 1 with the adhesive 13 applied to the back surface at a suitable position on the floor base 20. When the flooring 1 is simply placed, the adhesive layer 11 of the double-sided pressure-sensitive adhesive tape 10 does not exhibit adhesive strength, and when placed, the adhesive 13 is uncured, and the flooring 1 is on the floor substrate 20. You can move while sliding. Therefore, the operator moves the flooring 1 while sliding on the floor base 20 as shown in FIG. 4a, and accurately joins with the flooring 1a already fixed as shown in FIG. 4b. In this position, the flooring 1 is positioned.

  After positioning, the operator presses the flooring 1 toward the floor base 20 from above. By the pressing, the pressure-sensitive adhesive layer 11 of the double-sided pressure-sensitive adhesive tape 10 exhibits an adhesive force with respect to the floor base 20, and the flooring 1 is temporarily fixed at that position. Hereinafter, the same operation is performed for the other flooring 1. Since the floor material 1 arranged in front is temporarily fixed by the adhesive force of the adhesive layer 11 of the double-sided pressure-sensitive adhesive tape 10, the floor material 1 arranged in front in the process of temporarily fixing the floor material afterwards. , 1a is not displaced. By temporarily fixing all the flooring materials 1 and leaving them for a required time, the adhesive 13 applied to the back surface of the flooring material 1 is cured, and the flooring material 1 is permanently fixed to the floor base.

  As described above, in the flooring construction method according to the present invention, the double-sided pressure-sensitive adhesive tape 10 to be bonded to the back surface of the flooring 1 is used only for temporarily fixing the flooring, and the amount used is very small. That's it. For this reason, the cost associated with the double-sided pressure-sensitive adhesive tape 10 is reduced, and the work of peeling the release paper 12 and the work of disposing of the peeled release paper 12 are reduced, thereby improving the work efficiency. The main fixing of the flooring 1 to the floor base 20 is based on the adhesive force of the adhesive 13 applied to the back surface of the flooring 1, and a firm main fixing is obtained. Further, since there is a certain amount of time until the applied adhesive 13 is cured, the positioning of the flooring 1 on the floor base can be performed easily and reliably.

  In addition, in the present invention, the specification of the target floor base is arbitrary, and a plywood of about 12 mm thickness is pasted on a concrete slab, a particle board is placed on a joist, and finished with a mortar base. Examples can be given as examples.
