DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing floorboards, and more particularly to an improved method of laying a plurality of unit floorboards on a slab surface.

[0002]

2. Description of the Related Art In recent years, so-called flooring, in which a wooden floorboard is laid directly on a concrete slab or through a heat insulating material made of foam, has been widely used not only in middle- and high-rise houses but also in ordinary houses. Is coming. As the wooden floorboard, there are conventionally known many floorboards. Generally, as shown in FIG. 6, a unit floorboard in which a plurality of square plate bodies 10 are integrally assembled is used. FIG. 7 shows FIG.
1 shows a part of an AA cross section. As shown in the figure, each square plate body 10 is formed on four rounds of a wooden substrate 1 in which a plurality of thin wooden substrates such as a hard board and a particle board are laminated. 2 and female seeds 3 are formed, and decorative plywood 4 is adhered to the surface of them. At the factory, a plurality of the rectangular plate members 10 are gathered together in a state where the male and female members 3 are engaged with each other, and an appropriate adhesive such as hot melt resin 5 is injected into a lower portion where the male members 2 and female members 3 are further engaged. By doing so, it is shaped into a step-like shape as shown in FIG. Next, a cushion member 6 such as a foamed material such as a synthetic resin or a natural rubber or a fiber mat is adhered to the entire lower surface to form the unit floor panel A.

In the construction, a required number of unit floorboards A are carried into a construction site where slab construction has already been completed. Then, at the site, after applying a resin-based adhesive such as epoxy resin to a slab surface to be laid and laid such as a concrete slab, each unit floor plate A was formed on four rounds of adjacent unit floor plates. The real parts 2 and 3 are sequentially laid so as to engage with each other. The so-called flooring construction is completed by bonding the floorboards using unit floorboards (not shown) cut to appropriate dimensions in the four peripheral portions of the planned laying area. Instead of applying an adhesive to the slab surface, an adhesive is applied to the back surface of the unit floorboard and bonded to the slab surface.

[0004]

The above construction method is widely used because it can be reliably performed in any construction environment, but has some disadvantages. Not only is it difficult to apply the adhesive evenly over a large area, but it is also necessary to ensure that the unit floor panel is properly bonded to the slab surface, and to perform it quickly, making it difficult to lay And skill.

Further, since the entire back surface of the unit floor plate is stuck to the slab surface with an adhesive, the bonding is firmly and securely performed, but on the contrary, the unit floor plate is partially or wholly damaged. In such a case or for the purpose of changing the pattern, if the floorboard is to be partially or entirely replaced, it is not easy to remove the floorboard from the slab surface and it is difficult to work,
Irregularities are formed on the slab surface after peeling by the remaining adhesive and fragments of the wooden base material. Therefore, when newly bonding the unit floorboard, it is necessary to remove the residue such as the adhesive remaining on the slab surface in advance by some means and to flatten the surface, which requires much time and labor. . Due to this, it is a fact that re-placing the flooring is not always performed in spite of many demands.

Further, when the slab surface is a concrete slab, no particular problem occurs. However, a plate made of a foamed resin material or the like is interposed on the surface of the concrete slab for the purpose of heat insulation or soundproofing, and a floor plate is attached thereon. In such cases, the foamed resin material may be degraded or deformed by the adhesive depending on the type of adhesive, so care must be taken in selecting the adhesive. In some cases, the floor surface was distorted.

An object of the present invention is to provide a method of constructing a floorboard which solves the above-mentioned inconvenience when constructing a so-called flooring floor using a wooden floorboard. It is an object of the present invention to obtain a method of constructing a floorboard that can be reliably performed without requiring special skills, and that can easily be replaced with a once-constructed floorboard.

[0008] Still another object of the present invention is to provide a slab surface to be laid and constructed in a reliable and stable state without any particular adverse effect on the material constituting the slab, regardless of the material. An object of the present invention is to provide a method of constructing floorboards that can be laid.

[0009]

Means for Solving the Problems In order to solve the above-mentioned problems and achieve the object, as a first invention of the present application, 4
A construction method of laying and constructing a floorboard having a fruit formed on its periphery on a slab, without applying an adhesive to both the slab surface and the backside of the floorboard, and applying an adhesive only to the actual portion of the floorboard to be laid. The present invention discloses a method of constructing a floorboard, characterized in that a floorboard is laid on a slab by applying a predetermined area by sequentially applying real parts of the floorboards which are in contact with each other.

The present invention further provides, as a second invention, a construction method for laying and constructing a floor panel having four rounds of fruit on a slab, wherein the slab is provided only on the slab surface near the periphery of the area to be laid or on the periphery. Applying an adhesive only to the back surface of the floor plate located in the vicinity, applying an adhesive to the actual part of the floor plate to be laid, and sequentially joining the real parts of the adjoining floor plates to form a floor plate on the slab Disclosed is a method for constructing a floorboard, which is characterized by laying a predetermined area.

[0011]

When laying construction according to the first invention of the present application, an adhesive is applied to the actual part of the unit floorboard to be laid, preferably the lower side surface constituting the female seed, and the side part of the slab surface to be laid is constructed. To be installed sequentially. Next, an adhesive is similarly applied to the lower side surface of the separate unit floor panel that constitutes the female nut, and then laid on the already installed floor panel so that the mutual female nut and male nut are joined to each other. Hereinafter, the same operation is repeated to complete the laying work of the predetermined laying area. As a result, the unit floorboards which are close to each other are bonded and joined by the adhesive applied to one of the female floors and the male floor of the other unit floorboard which is engaged therewith. The flooring is bonded to each other.

In the construction according to the second aspect of the invention, the adhesive is applied in advance near the side of the slab surface to be laid and the adhesive is applied only to the back surface of the floorboard located near the periphery. Executing the construction of the first invention. In this case, the unit floorboard laid in the peripheral portion of the floor surface is bonded to the slab surface in addition to the adhesive bonding at the actual portions of the adjacent unit floorboards. This construction method is effective for construction over a large area.

[0013]

The present invention will be described below in more detail with reference to examples. 1 to 4 show unit floorboards B suitable for the practice of the present invention.
FIG. As the unit floor plate B, the unit floor plate conventionally used as described above can be used as it is. However, as shown in the figure, the shape of the actual portion is changed to a male fruit and a female fruit having a large bite amount and flat surfaces 21 and 21 as shown in the figure. This is a preferred embodiment, whereby the bonding area between the unit floorboards can be increased, and a more stable roofering surface can be formed.

[0014] 22 is a decorative plate portion constitutes the surface of the flooring surface, but Ru usually consists of plywood, a decorative plate having a substrate and MDF (medium density fiberboard), etc. Is also good. Reference numeral 23 denotes a wooden board portion which constitutes a substantial thickness portion of the unit floorboard, and is made of a material such as a hard board or a particle board, which has a relatively large specific gravity as compared with an ordinary Rawan plywood as shown in the above-mentioned conventional example. It consists of . Thereby, stability after construction is ensured. Numeral 24 is a cushion material made of a material such as a foam or a fiber mat, such as synthetic resin or natural rubber, adhered to the entire lower surface, and is adapted to be able to adapt to the unevenness of the slab surface. The wood board 23 is provided with a notch 25 formed in a direction perpendicular to the longitudinal direction (the left-right direction in FIG. 1) of the unit floor board B, and the unit floor board is adapted to the unevenness of the slab surface and easily adheres. Formed for purpose.

FIG. 2 shows a modification of the unit floor panel.
In this unit floor panel, an elastic sheet 26 is interposed between the decorative panel section 23 and the wooden board section 24 as an intermediate sheet to improve functions such as cushioning, vibration suppression, and sound insulation. FIG.
Shows another modification of the unit floorboard. This unit floorboard has a sound insulation sheet 27 interposed between a wooden board portion 24 and a cushion material 24. Generally, the sound insulation sheet is a material having a relatively large specific gravity, such as a PVC sheet mixed with lead powder. Therefore, the unit floorboard of this embodiment has an effect of maintaining a more stable state after construction.

FIG. 4 shows still another modification of the unit floor panel, in which both an elastic sheet 26 and a sound insulation sheet 27 are interposed. Unit floor plate B used in the present invention
Is a rectangular plate 10 having a sectional shape as shown in FIGS.
May be combined to form a step-like shape as shown in FIG. 6, or the whole may be formed into a similar shape by a single member. Also, the overall shape is not limited to the step shape, and a unit floor plate having an arbitrary shape such as a square can be used as long as male and female fruits can be formed on four sides.

Such a unit floor plate B is laid on the slab surface C. The slab surface C may be the concrete slab surface itself, or may be a concrete slab surface on which a foam as a heat insulating material is laid. First, a unit floor plate B is installed on preferably a side portion of a slab surface to be laid (FIG. 5 shows a state where only one unit floor plate is laid). At this time, an adhesive is applied to the actual portion of each unit floorboard, preferably to the lower surface 30 of the female nut 3 (the portion shown in a sand pattern in FIG. 5). After arranging one row along the side, apply glue to the lower floor surface of the female floor of the next row in the same way, then the female floor and the male floor Lay so as to join. Hereinafter, the same operation is repeated to complete the laying work of the predetermined laying area.

As another construction method, an area 40 (similarly shown in FIG. 5 in the form of sand) may be formed near the side of the slab surface to be laid. Subsequent construction is performed in the same manner as described above. Also,
As another construction method, an adhesive may be applied in advance to the back surface of the unit floor plate installed on the side portion of the slab surface to be laid. In the case of using the above construction method, the unit floor plate located in the peripheral part of the construction floor surface will be bonded to the slab surface with an adhesive, so that when constructing over a large area, obtain a stable floor surface Can be.

[0019]

According to the construction method of the present invention, unit floorboards that are close to each other are bonded and bonded only to the actual portions that engage with each other, that is, they are not bonded to the slab surface at all. (Or in a state where only the side of the slab surface is bonded and bonded), flooring work can be performed, so that each unit slab can be quickly and easily installed on the slab surface. In the flooring constructed according to the present invention, when the floorboard is to be replaced for some reason, not only can the existing unit floorboard be easily peeled off from the slab surface, but also the slab surface after the peeling is performed. However, when an adhesive is applied to the vicinity of the side, the same flat surface immediately after slab construction is maintained except for that part, and the workability at the time of re-placing can be greatly improved. That. Further, in the floorboard according to the present invention, a fruit is formed on four circumferences, and a material having a relatively large specific gravity is disposed in the intermediate layer and the lower layer portion of the floorboard, and the intermediate layer member substantially constituting the thickness portion is provided. Because it has a notch that extends from the front surface to the back surface in a direction perpendicular to the longitudinal direction, even in the above-mentioned construction method that does not use adhesive, it follows the slab surface well and remains stable after being laid Can be maintained.
