Description

The present invention relates to a wooden flooring construction method used in houses, stores, offices, and the like, and more particularly to a flooring construction method that requires site recovery, such as rental properties and temporary exhibition halls.

2. Description of the Related Art Conventionally, in a flooring re-installation method, there is known a straightening method in which an existing flooring is peeled off and a floor material having a special sane shape is attached to a veneer or the like, or directly attached to a concrete slab.

However, in the above construction method, the flooring is fixed by sticking the wooden flooring directly to the existing flooring using a nail or an adhesive, so it takes construction period and cost, and the flooring is damaged when removed. Therefore, it cannot be reused, and a large amount of garbage including waste materials is also produced.

Therefore, a method has been proposed in which a wooden flooring is bonded to an existing flooring material using a peel-up bond such as a modified silicone bond or an acrylic emulsion bond. Peel-up type bonds have the property that they do not lose their tackiness indefinitely even after drying. Immediately after application, the color is white. In this state, there is no adhesive force, and when it becomes transparent, sufficient adhesive force is produced.

In Patent Document 1, an existing flooring is bonded to a new flooring provided with either a vinyl chloride layer, a polyethylene layer, or a polypropylene layer on a sticking surface using a modified silicon adhesive. A construction method is disclosed.

JP 2014-173224 A

However, in the conventional peel-up method represented by Patent Document 1, a peel-up bond is uniformly applied in an amount of 60 to 100 g / square meter with a roller iron or a flat iron on both the construction surface and the wooden flooring material with sash. , The adhesive is transparent (after sufficient adhesive force has been generated), and it is pasted while crimping. It was. Further, since the above amount of peel-up bond is applied to the entire surface of the wooden flooring material, the adhesive strength is large, and in the case of temporary flooring, there is a problem that it takes time to remove.
Then, this invention makes it a subject to provide the flooring construction method which the construction work and removal work of wood type flooring are easy, and can reuse the wood type flooring after removal.

In the flooring construction method of the present invention, a foamed urethane sheet is laid on the construction surface, and then a wooden flooring is laid on the construction surface sequentially from the construction edge using a peel-up type bond.
Below, the flooring construction method of this invention is demonstrated based on FIGS.

(1) The foamed urethane sheet 1 shown in FIG. 1 having an expansion ratio of 10 to 40, a thickness of 3 to 12 millimeters, and a width of 45 to 200 centimeters is spread on the floor on which the construction is performed. At this time, the urethane sheet 1 and the floor are basically not bonded, but may be bonded if necessary.
(2) The peel-up bond 3 is uniform as shown in FIG. Apply with a roller.
(3) When the peel-up bond becomes transparent, the wood flooring 2 is attached to the urethane sheet 1 and pressure-bonded from above. In order to obtain a sufficient adhesive strength, it is necessary to perform construction when the peel-up bond becomes transparent.
(4) In the second and subsequent rows, the peel-up bond 4 is applied to the foamed urethane sheet 1 side only in a mottled amount as shown in FIG.
(5) In a white state immediately after the peel-up bond 4 is applied, the wood flooring 2 is attached to the urethane sheet 3 without being crimped, and positioning is performed by fitting the sash. If the peel-up bond is white, the adhesive force has not yet been generated, and positioning is easy.
(6) The wooden flooring 2 is stretched in the steps (4) to (5) until it reaches 180 cm in the short direction of the wooden flooring 2, and after 180 cm, the above ( Repeat steps 2) to (5). When the procedure (2) is entered every 180 centimeters, it is possible to prevent any misalignment in units of 180 centimeters.
(7) In the final row, the wood flooring 2 is attached to the foamed urethane sheet 1 by the method of (2) to (3) above, and is crimped from above. Similar to the first row, the adhesive force is strengthened, thereby preventing the displacement of the entire flooring. In addition, if all the flooring 2 is pasted on the urethane sheet 3 after the peel-up bond 4 becomes transparent, the construction becomes difficult.

The existing floors on which foamed urethane sheets are spread are general flooring materials such as concrete, wood, cushion floor, P tile, cork, carpet with short hairs and tatami mats. At this time, the urethane sheets may be just abutted or temporarily fixed with an adhesive tape. However, in order to prevent the foamed urethane sheet from being pushed up due to expansion and contraction, it is always necessary to leave a space of 3 mm or more around the room.

The peel-up bond is selected from a modified silicone bond, an acrylic emulsion bond, and the like.

By applying peel-up bond to both the urethane sheet and the wooden flooring every 180 centimeters as in the above procedure to increase the adhesive force, the wooden flooring can be prevented from shifting, and in the meantime, the urethane flooring can be prevented. By reducing the adhesive force by applying only to the sheet side, construction work and removal work can be facilitated, and the wood flooring can be reused. Further, when peeling off the flooring that has already been pasted for position correction during construction, the urethane sheet is stretched, so that the operation of disengaging the sash portion is easy. Furthermore, when peeling off the entire flooring at the time of removal, the urethane sheet can be lifted and the urethane sheet can be peeled off from the flooring.

According to the present invention, the construction work can be easily performed without any deviation of the wooden flooring, the removal work for on-site restoration is easy, and the wooden flooring can be reused.

It is a figure of the construction method concerning procedure (2)-(3) of embodiment of this invention. It is a figure of the construction method concerning procedure (4)-(5) of embodiment of this invention. It is a figure of the construction method concerning the procedure (6) of embodiment of this invention.

In the following examples and comparative examples, a urethane floor having a foaming ratio of 10, a thickness of 4 millimeters, and a width of 100 centimeters is laid down on a floor on which a wooden flooring with vines having a width of 140 millimeters and a length of 900 millimeters is placed. I pasted it.

(Example) Construction was carried out according to the following procedure.
(1) Peel-up bond was applied to the back surface of the wooden flooring and the foamed urethane sheet with a roller in an amount of 60 to 100 g / square meter.
(2) When the peel-up bond became transparent, the wood flooring was attached to a urethane sheet and pressure-bonded from above.
(3) In the second and subsequent rows, peel-up bonds are applied to the urethane sheet only in an amount of 10 to 30 g / square meter. It stuck without crimping, and the positioning was performed by fitting the steel.
(4) The wooden flooring is stretched in the procedure of (2) to (3) until it becomes 180 cm in the short direction of the wooden flooring, and after 180 cm, the procedure of (2) to (3) above Was repeated.
(5) In the final row, the wooden flooring was attached to the urethane sheet by the method of (1) to (2) above, and pressure-bonded from above, and after 60 minutes, all the wooden flooring was pressure-bonded.

(Comparative example) Construction was performed according to the following procedure.
(1) Peel-up bond was applied to the back surface of the wooden flooring and the foamed urethane sheet with a roller in an amount of 60 to 100 g / square meter.
(2) When the peel-up bond became transparent, the peel-up bond was applied with a roller in an amount of 60 to 100 g / sq.m.

In the construction method shown in the Examples, the slippage was easily corrected by sliding the wooden flooring, and the sane portion could be fitted, and the construction work was completed in a short time. In addition, the wood flooring can be easily removed, and the wood flooring can be reused without being damaged.

In the construction method shown in the comparative example, it was not easy to slide the wooden flooring, and it was difficult to correct the deviation, so that the construction work took a long time compared to the example. Moreover, since all the wooden flooring was adhered relatively firmly, it took time for the removal work.

In addition, when the urethane sheet used in the present invention has too large a thickness and a foaming ratio, the walking feeling when walking on the floor is deteriorated. The foaming ratio and thickness of the urethane sheet that does not deteriorate walking feeling are 3 mm to 12 mm at a foaming ratio of 10 times, 3 mm to 8 mm at a foaming ratio of 15 to 35 times, and 3 mm to 8 mm at a foaming ratio of 40 times. 5 millimeters.

INDUSTRIAL APPLICABILITY The present invention is useful as a wooden flooring construction method used in houses, stores, offices, etc., particularly as a flooring construction method that requires site recovery, such as rental properties and temporary exhibition halls.
