Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a floor construction method, particularly to a finishing construction method for floors of medium- and high-rise residential buildings.

[Conventional technology]

As conventional flooring materials, those shown in FIGS. 7 and 8 are known. The floor material 1 is formed in a rectangular shape and has a decorative layer 3 layered on the upper surface of a plywood substrate 2. The bottom of the flooring 1 has an overhang 4 on one side edge.

The other side edge has a notch 5, which allows a plurality of flooring materials 1 to be joined in parallel as shown in the figure. The floor material 1 is directly laid on the foundation floor surface, and specifically, after nails 6 are nailed to the foundation floor surface from the overhang portion 4 for one piece of floor material 1, the overhang portion 4 is inserted into the notch. The next flooring material 1 is placed so as to be covered by the section 5, and the flooring materials are laid one after another.

[The problem that the invention attempts to solve]

When using the conventional construction method, each flooring material 1 is fixed to the foundation floor surface with nails 6, but the locations where the nails 6 can be used are limited to the overhang portion 4. Because of this, the nail 6 cannot be nailed into the central part of the cover and flooring material 1, which is not sufficiently fixed, and there is a risk of creating a gap between the lid and the foundation floor surface.

In addition, wooden boards such as plywood expand and contract depending on humidity, and after the flooring material 1 is laid, in high humidity, the flooring material 1 expands and stretches in the longitudinal direction, pushing up the longitudinal ends of each other and causing 7
There is a problem that the floor material 1 warps as shown by the chain line in the figure, and on the other hand, at low humidity, the flooring material 1 contracts and creates gaps between the longitudinal ends, which leads to the problem of poor finishing. do.

Furthermore, in mid-to-high-rise residential buildings, consideration must be given to prevent noise such as footsteps from being transmitted to the floor below, but conventional methods have not been able to satisfy this problem.

[Means for solving problems]

The present invention aims to provide a floor construction method that solves the above-mentioned problems, and is characterized in that a plurality of rectangular base plates 10 and a plurality of rectangular base plates 10 are used. Finishing plate 11 and 4! Preparation: The base plate IO has an elastic Ji 13 formed on at least the lower surface of the wooden substrate 12, and the finishing plate 11 is formed in a thin sheet shape having a decorative surface 15 on the upper surface of the wooden substrate 14. After laying and fixing the base plate 10 directly on the foundation floor surface with the elastic layer 13 facing downward and the longitudinal direction of multiple base plates parallel to each other, finish vi1 in the longitudinal direction of the base plate 10.
A plurality of finished plates are laid and fixed on the base plate parallel to each other with the decorative surfaces 15 facing upward, with the longitudinal directions of the finishing plates perpendicular to each other.

However, according to the present invention, since the flooring material is divided into the base board 10 and the finishing board 11, the base material 1
0 can be reliably fixed to the base floor surface using nails and/or adhesives, etc., and the finishing board 11 can be laid and fixed on the base board 10. In particular, the base plate 10 and the finishing plate l
(1) and 0M are polymerized so that their longitudinal directions are perpendicular to each other, so the effect of high and low humidity is extremely small and a beautiful finish can be guaranteed. Although it does not prevent
Push-up due to expansion is suitably suppressed from above by the finishing plate 11 that is perpendicular to the longitudinal direction. Furthermore, since the finishing plate 11 itself is formed in the form of a thin sheet, the rate of expansion and contraction in the longitudinal direction is extremely small, and even when expansion and contraction due to humidity differences occurs, there is no noticeable finish defect as in the past.

Moreover, when laying the finishing plate after laying and fixing the base plate, the finishing plate 11 can be cut into a thin sheet shape using a cutter.

Accurate machining near walls is easy, which not only improves work efficiency but also leads to better material yields.

Furthermore, since the base plate 10 has an elastic layer 13 on the lower surface, this serves as a soundproofing material and has an excellent soundproofing effect on the upper and lower floors, and also absorbs the height of the foundation floor surface during construction and improves the finished state. You can also do it.

〔Example〕

Embodiments of the present invention will be described in detail based on the drawings.

In the present invention, a base board 10 and a finishing board 11 are used as flooring materials.
is prepared.

The base plate 10 is made of a wooden substrate 12, as shown in FIGS.
An elastic layer 13 is formed on the lower surface of the rectangular plate having a total thickness of approximately 6 mm to 8 mm. The wooden board 12 is made of 3-ply plywood with a thickness of about 41 mm, and has tongues on one side edge, that is, a protrusion 16 on one side edge and a ridge 117 on the other side edge. The elastic layer 13 is formed by foaming a mixture of polyolefin resin and gypsum inorganic material to a thickness of about 100 cm.
A sheet having a diameter of 4 mm to 4 mm is bonded to the plywood 12 via an adhesive layer 18. Base plate 10
The rectangular dimensions are 1 shaku x 6 shaku, or 2 shaku x 6 shaku,
Or selected from each size of 3 shaku x 6 shaku.

The finishing board 11 is a wooden substrate 14, as shown in FIGS.
A decorative surface 15 is formed on the upper surface of the.

A girder 19 is attached to the lower surface, and a double-sided adhesive tape 20 is further preferably provided on the lower surface of the girder 19, and the girder 9 is formed into a thin rectangular sheet having a total thickness of about 2.7 fl. be done. The wood substrate 14 is made of 3-ply plywood having a thickness of about 2.51 mm. The decorative surface 15 is made of a decorative veneer 21 made of natural wood with a thickness of about 0.28 mm.
The surface of the decorative veneer 21 is adhered via an adhesive layer 22, and the surface of the decorative veneer 21 is finished with a coating 23. Said G19
is about 20g/m, and the plywood 1 is attached via adhesive.
The double-sided adhesive tape 20 adhered to the back side of the base plate 4 is a known type having an adhesive on the front and back sides of the base material. There are multiple pieces glued together at intervals.

Such an adhesive tape 20 is not necessarily required for the finishing plate 11 used in the present invention.Although not shown in the drawings, a release tape is laminated on the adhesive surface of the double-sided adhesive tape 20. The rectangular dimensions of the finishing plate 11 are selected from the following dimensions: 1 shaku x 6 shaku, 1 shaku x 3 shaku, or 1 shaku x 2 shaku.

To explain the floor construction method of the present invention using the base board 10 and finishing board 11 described above, first, the foundation floor of a building to which the floor is to be constructed is mainly a mortar floor of a mid-to-high-rise residential building, and therefore If the unevenness of the floor surface is significant, prepare the unevenness using a carving tool or the like to reduce the unevenness to less than 2 to 3 degrees.After that, take into consideration material loss and corner settlement on the foundation floor surface.

The construction method of the present invention is performed in the following order.

(First step) Clean the foundation floor surface, and apply 350 to 400 g/rn' of concrete adhesive (for example, epoxy adhesive under the trade name Konishi E350 R) or other adhesive using a comb-toothed trowel.
is applied as a guide, and the base plate 10 is laid on top of it in a brick-like manner, with the elastic layer 13 facing the adhesive.
(Fig.) or in a patched manner. At this time, the plurality of base plates 10 are arranged parallel to each other in the longitudinal direction, and the projecting edges 16
and the grooves 17 are fitted into each other so that they are tongue-and-groove connected.

Incidentally, the base plate 10 placed next to the wall is cut as appropriate to match the dimensions of one room.6 Note that instead of using the adhesive, the base plate 10 may be fixed to the foundation floor surface with nails. Furthermore, it is also possible to use the adhesive and nails together.

(Second Step) The finishing plate 11 is laid and fixed on top of the laid base plate 10 in a brick-like manner (FIG. 1) or in a laminated-like manner. Preferably, when pasting the finishing plate 11, it is pasted while pressing diagonally in the longitudinal direction so that there is no gap.
The surfaces are pressed down with hands and stepped on with feet, and the joints are pressed down with hand iron rolls. At this time, the finishing boards 11 are arranged so that their longitudinal directions are parallel to each other but orthogonal to the longitudinal direction of the base board 1o.

It goes without saying that the decorative surface 15 of the finishing plate 11 faces upward, and it is fixed onto the base plate 10 using double-sided adhesive tape 2° on the back side.

If the finishing plate 11 is not equipped with the adhesive tape 20, an appropriate adhesive is applied to the surface of the base plate IO.Incidentally, the finishing plates 11 are joined by butt to make them flush. The finishing plate 11 placed next to the wall is cut to size using a cutter knife or the like. More preferably, it is possible to drive temporary nails to finish pasting.

Although not shown in the drawings, it is preferable that the finishing plate 11 is finished in advance so that it curves gently into a convex shape on the decorative surface side.

The repulsive force of the convex warp on the cover is 1/0 compared to the concave warp of plywood, and the end portion of the finished board 11 transitions to a concave warp after crimping with the double-sided adhesive tape 20. It is possible to maintain a beautiful finish for a long time.

〔Effect of the invention〕

As a result of the present invention configured as described above, the flooring material is divided into the base board 10 and the finishing board 11. Therefore, during construction, the base material IO can be attached to the base floor surface using nails and/or adhesives. It can be firmly and easily fixed to the base plate l.
A finishing plate 11 can be laid and fixed on the O. In particular, since the base plate 10 and the finishing plate 11 are superposed so that their longitudinal directions are orthogonal to each other, there is no push-up of the joint part or generation of voids due to humidity levels, which is the case with conventional methods, and a beautiful finish can be maintained for a long period of time. 1M, which can be guaranteed, and the upthrust of the joint part due to expansion of the base plate 10 is suitably suppressed from above by the finishing plate 11 that is perpendicular to the longitudinal direction, and since the finishing plate 11 itself is formed in a thin sheet shape, The expansion and contraction ratio is extremely small, and the gap between the joints due to shrinkage due to low humidity is also narrow.

There is almost no effect on the appearance.

Moreover, when laying the finishing plate after laying and fixing the base plate, the finishing plate 11 can be cut into a thin, sorted piece with a cutter.

It is easy to perform accurate machining near walls, and it is also easy to finish near walls in rooms where gray water is not used, such as in modern condominiums, which not only improves work efficiency but also improves material yield. invite.

Furthermore, since the base plate 10 has an elastic layer 13 on the lower surface, this serves as a soundproofing material and has an excellent soundproofing effect on the upper and lower floors, and also absorbs the height of the foundation floor surface during construction and improves the finished state. You can also do it.

5. The conventional interior construction procedure for a living room is in the order of floor - wall - ceiling - one fixture, and it is impossible to avoid problems such as the floor surface that is finished first getting dirty, broken, or damaged during later work. However, according to the present invention, it is possible to lay the base board for the floor in the order of laying the base board for the floor, then the finishing board for one wall, one ceiling, one fitting, and one floor, which eliminates the need for curing and other steps. It also has the effect of keeping it beautiful.
