Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure which can easily and surely bond floor plates together without using adhesives, nails, staples, etc. when installing a floor of a building such as a house. It is a member, and is particularly suitable for installation of a reform floor plate.

[0002]

2. Description of the Related Art Conventionally, floor installation methods for buildings such as houses are roughly divided into joist attachment method and direct attachment method. The joist attachment method applies an adhesive on the joist, and puts a floor board on it. It is a construction method in which nails are fixed to the joists on the side wall of the floorboard, and the direct-adhesion construction method is a construction method in which a direct-adhesion adhesive is applied on the floor base material and the floorboard is fixed only by this adhesive. On the other hand, when it is desired to refurbish an old floorboard, there is a method in which all the old floorboards are peeled off, the adhesive is removed, and if necessary, the base material or joists are replaced and reattached. Since this method is the same as the installation of a new floor, it can be reformed by the conventional joisting method or direct method. However, when it is desired to perform the reforming more simply, the old floorboard is not forcibly peeled off, and the floorboard for the reform is attached to the old floorboard.

In this case, if the thickness of the floor plate for reforming is large, in addition to the problem that the step difference of the floor itself becomes large between the reformed portion and the non-reformed portion, the interior door, the door frame, and the closet. There are various problems such as difficulty in adjusting the height dimension of a fitting door such as a folding door door, a fitting such as a folding door frame, and an opening member. Therefore, the thickness of the floor plate for the reform is preferably as thin as possible, and preferably 2.5 mm to 5.
It has been considered that 0 mm is ideal.

However, with such a thickness, the actual machining, which is the most common method for joining the floorboards and has a high binding strength between the floorboards, cannot be done because the floorboards are too thin. Similarly, in the method using employment that has a high binding strength, it is difficult to provide sufficient strength because the floor board is too thin.

Therefore, in the construction of the floorboard for reforming, the floorboard for reforming was adhered to the original old floor surface with an adhesive and fixed from the surface of the floorboard for reforming with nails or staples.

[0006] However, a considerable technique is required to apply an adhesive to a large area and to bond them together properly, and there are also safety problems such as volatilization of the solvent and odor. Hitting or stapling causes rusting or catching, which is not desirable in terms of usability and design. Further, it is extremely difficult to cleanly remove the floor plate once it is re-formed in the future when the floor plate is once constructed by using the adhesive and nails or staples together. There has been a demand for improvement in the method of constructing such a thin floor plate for remodeling.

[0007]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a means by which a floor can be installed without using adhesives, nails or staples. -The application of means suitable for the system. That is, even if a thin reforming floor plate is used for floor reforming, there is no fear of damage to the floor plate end due to its strength, and no adhesive, nails, staples, etc. are used. The floor boards can be easily and reliably joined and bonded together,
There is no risk of gaps, warpage, steps, etc. after construction, and a floor component member that can easily peel off and remove the old floor plate when reforming again in the future, and a floor formed using this member. Is provided.

[0008]

In order to achieve the above object, a floor constituting member according to the present invention comprises a floor plate having a concave portion on a side surface and a floor plate which is inserted into a concave portion on a side surface of a floor plate to tightly bond adjacent floor plates to each other. It is a floor which is composed of locking members having inverted hook-shaped locking portions at both ends thereof and which is tightly bonded by inserting locking members having the above-mentioned inverted hook-shaped locking portions into concave portions of adjacent floor plates facing each other. The thickness of the floor board is thin from 2.5 mm to 5.0 mm, which is suitable for a floor material suitable for remodeling.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A floor plate and a locking member which are floor constituent members according to the present invention, and a floor constituted by using these members will be described in detail below with reference to the drawings. 1 is a perspective view showing an example of an embodiment of the floorboard of the present invention, FIG. 2 is a perspective view showing another embodiment of the floorboard of the present invention, and FIG. 3 is an enlarged sectional view taken along the line AA of FIGS. 1 and 2.

As shown in FIGS. 1 and 2, the floorboard 1 of the present invention has a decorative material 3 adhered to the surface of a wooden plate-like substrate 2, and the plate-like substrate 2 has opposite side surfaces. The groove 4 or the concave hole 5 is provided as a concave portion at a predetermined interval. The recesses are provided on the four side surfaces of the plate-shaped substrate 2 that face each other, but the floor plates used for the end portions of the floor may be provided on only the necessary side surfaces. The number of recesses is at least two, and it is preferable to provide more recesses in order to increase the binding strength. In the case of a room where changes in moisture absorption and dryness are drastic, it is necessary to increase the degree of tightness between the recess and the locking portion.

The depth of the recess is half the length L1 of the locking member 6 or slightly shorter. The tightness is increased by making the length a little shorter. If guide grooves or guide holes as shown by reference numerals g and h in the figure are provided on the bottom surface of the recess, the locking member 6 having a sharp tip is temporarily fixed along the guide groove g or the guide hole h. The workability of sticking is improved.

As the plate-shaped substrate 2, plywood, slab,
Textile plates, lumber, etc. can be used, but other than these may be used. The thickness of the plate-shaped substrate 2 is not particularly limited, but is 2.5 m, which is optimal as a floor plate for a reform.
The locking member 6 of the present invention when the thickness is as thin as m to 5.0 mm
You can exert the power of. When a floor plate having a thin thickness is adopted, the base material portions above and below the groove or the recessed hole provided on the side surface of the floor plate can be thickened, so that there is no possibility of damaging the base material during construction.

As the surface decorative material 3, wood veneer or veneer, synthetic resin decorative sheet, paper decorative sheet, etc. can be used, but the material is not limited to these. Decorative material 3
The pasting method may be a conventional method.

The surface of the floorboard is coated with a conventional paint or coating method. For example, a thermosetting type, an ultraviolet ray curing type, an electron beam curing type urethane resin coating material, an aminoalkyd resin coating material, or the like is used for coating with a roll coater or a flow coater. Further, it may be other than these.

The depth of the groove 4 provided on the side surface of the plate-shaped substrate 2 is optimally about 3.0 mm to 5.0 mm. Further, the width of the groove 4 is such that the thickness of the plate-shaped substrate 2 is 2.5 to
The optimum value of 5.0 mm is about 1.0 to 2.0 mm.

On the other hand, as shown in FIG. 4 (a), the locking member 6 which is inserted into the recess and tightly connects the floorboard of the present invention has a locking portion 6a whose tip is an inverted hook shape. The number of inverted hook-shaped engaging portions is not particularly limited, but when provided on the entire circumference around the tip of the engaging member 6, the effect as an engaging portion is rather reduced, so two pieces are seen from the front. It is preferable that the number is about 6 pieces. FIG. 4B shows four examples when viewed from the front. Further, it is suitable that the number of the inverted hook-shaped engaging portions as viewed from the side is about 2 to 6. FIG. 4A shows six examples as viewed from the side.

Further, the planar shape of the locking member 6 can be variously varied, and examples thereof are shown in FIGS. (C) to (C) show rod-shaped locking members,
(I) to (e) show a flat plate-like locking member. As an example of a rod-shaped locking member, (C) is one rod-shaped body provided with inverted hooks at both ends, (D) is a side view thereof, and (E) is the tip of a bar-shaped body bent in a crank shape. (H) is a side view showing a hook provided with inverted hooks, and (G) is a side view showing an H-shaped rod as a whole with both ends of a horizontal portion. Further, as an example of a flat plate-like locking member, (i) is a flat plate with thickness decreasing toward the tip, and inverted hooks are provided at both ends of the flat plate. A flat inverted hook is provided at both ends of a flat plate whose thickness decreases toward, and (e) is a side view thereof. As described above, various variations can be exemplified. It is not limited to these variations.

The shape of one rod-shaped body as shown in FIGS. 4 (c) and 4 (d) is easy to manufacture, but since both tips are sharp, it requires careful handling. In this respect, (e),
(F), (to), (chi), (ri), (nu), (ru),
(E) is easy to handle. Especially (ri), (nu),
The flat shape shown in (L) and (E) is the degree of tightness,
It is most suitable in terms of prevention of falling out and handling, and the H-shaped ones such as (G) and (H) are next suitable.

In the case of the flat plate-shaped locking member, the length in the longitudinal direction may be the length of the entire length of the groove 4, but short lengths may be used at predetermined intervals. The easy-to-use length of the flat plate-like locking member is approximately 30 mm to 200 mm. Regarding the dimensions of the flat plate-like locking member to be inserted into the groove 4, the length L1 of the locking member is approximately 10 to 15 mm, the length L2 of the inverted hook-shaped locking portion is approximately 2.0 to 6.0 mm, The thickness L3 of the locking member is preferably about 1.5 to 3.0 mm.

The groove 4 may be provided over the entire length of the side surface of the floor plate 1, but short grooves may be provided at a predetermined position on the side surface of the floor plate 1 at a predetermined interval. The number of the grooves 4 is about 3 to 7 in the longitudinal direction of the floorboard 1 and 2 in the lateral direction of the floorboard 1.
About 3 is suitable. The length of the short groove 4 is preferably about 30 mm to 200 mm.

The size of the concave hole 5 is the plate-like base material 2.
If the thickness is 2.5 to 5.0 mm, the diameter is about 1.0 to
The optimum value is about 2.0 mm. Further, the depth of the concave hole 5 is optimally about 3.0 mm to 5.0 mm. Also,
The optimal interval for providing the concave holes 5 is about 10 mm to 300 mm. The shape of the concave hole 5 may be a shape other than the round hole shape. The shape of the recessed hole 5 is not limited as long as it is within the range of common sense, but if it is a round hole, even an amateur can easily perform drilling with a woodworking drill or the like.

A rod-shaped locking member is suitable for the recess 5. The number of rod-shaped locking members used is 7 in the longitudinal direction of the floorboard.
About 20 pieces, and about 2 to 5 pieces in the lateral direction of the floorboard are preferable. Also in this case, the locking member 6 may have the same sectional shape and size as the flat plate-shaped locking member, as shown in FIG. Further, when the concave portion provided on the side surface of the plate-shaped substrate 2 has a groove shape, the locking member 6 may have a rod-shaped flat plate shape. It is also possible to mix and use both.

The material of the locking member 6 can be made of iron, brass, aluminum, stainless steel, other metal, or synthetic resin such as hard vinyl chloride. Further, other materials may be used as long as they are materials having general hardness and strength as a binding jig for wood materials, but the above-mentioned metal materials are most suitable.

Further, the groove 4 provided on the side surface of the plate-shaped substrate 2
If the guide groove g or the guide hole h for the locking member is provided on the bottom of the base or the bottom of the recessed hole 5, the position where the locking member 6 is attached becomes clear at the time of construction, and the locking member 6 is temporarily fixed. It has a merit that it can be stored and it is very easy to construct.

When constructing the floorboard 1 of the present invention, the construction procedure when the concave portion on the side surface of the floorboard is the groove 4 will be described in detail. First, no adhesive is needed on the floor substrate. The floorboard 1 is laid out in consideration of the balance of the entire room, and a layout line for construction is drawn. Next, the floor boards 1 of the present invention are tentatively arranged in consideration of the color pattern arrangement on the surface of the decorative material 3 and the accommodation of the end portion of the room. Then, the first floorboard 1 is placed at a predetermined position on the floor base. At this time, only the first floor plate 1 is firmly fixed on the floor base material using nails and staples.

Next, one or more one of the locking portions 6a of the locking member 6 having a flat plate shape or a rod shape is inserted into a predetermined position of the groove 4 provided on the side surface of the first floor plate 1. When there is a guide groove g, the tip of the engaging portion 6a is pierced into the guide groove g to temporarily fix it, and is hammered in to fix both floor boards. In this case, if the total length of the locking members 6 is about 25% or more of the length of the floorboard side surface, the binding strength, warpage after construction,
Most preferred for steps.

Next, the groove 4 of the adjacent second floor plate is fitted into the locking member 6 protruding from the side surface of the first floor plate,
Strike the other end of the second floorboard with a mallet or the like through a batten to completely bond the floorboards together. Subsequently, the third and subsequent floor plates are similarly tightly bound via the locking member 6 and sequentially constructed.

Also, when the concave portion provided on the side surface of the plate-shaped substrate 2 is a concave hole instead of a groove, the construction procedure is the same.
In this case, as a matter of course, only the rod-shaped locking member 6 can be used.

If the floor base material is an old carpet or the like and has some cushioning properties, after the floor plate for a reform of the present invention is constructed, it is necessary to step evenly and sufficiently around the floor plate joint with the foot. , The binding force between the floor boards is further increased. The reason for this is that if the floor base has cushioning properties, when a load is applied from above at the floor plate joint, the floor plate moves up and down, and the locking member penetrates deeper into the groove, further increasing the binding force between the floor plates. To do.

[0030]

As described above, according to the floor constituting member of the present invention, even if a floor plate having a thin thickness is adopted, the thickness of the base material portion above and below the groove or the concave hole provided on the side surface of the floor plate. Since it can be thickened, there is no risk of damage to that part during construction.

Further, since no adhesives, nails, staples, etc. are used, the construction work is inexpensive and the construction cost is low, so that even an layperson can perform the construction very easily. The floor boards can be reliably joined together without the need for a professional worker.

Further, the tight binding strength between the floor boards after the construction is great, and after the construction, the construction can be surely carried out without fear of gaps, warps, steps, etc. due to the variation of the water content of the floor boards.

Since no adhesives, nails, staples, etc. are used, the old floorboards can be peeled off and removed very easily in the case of reforming in the future, and by using no adhesives, The effect is that there is less risk of health hazards due to formaldehyde odor, etc. for both the person performing the construction and the person living there after the construction.
