The present invention relates to a floor finishing flooring material, and more particularly, the flexible flooring construction in the vertical direction with the adjacent flooring material is possible to improve the construction workability improved floorboard material for construction, especially S-line It relates to a floorboard material in which the fastening is maintained.

BACKGROUND ART Floorboard materials which can be formed by assembling iron protrusions and grooves in a side (edge) in advance are commonly used. Such a floorboard material can be installed by a person skilled in the art while easy to install while solving the problem of being attached to the bottom floor by an adhesive or fixed by fixing the bottom floor with a fastening means or the like. These floorboard materials are generally composed of surface layers such as lacquers or laminates. According to Korean Patent Registration No. 394968 (floor finishing flooring material comprising ondol) disclosed by the present inventors, in the floor finishing flooring material manufactured by using a unit disc, the side insertion portion at one end in the longitudinal direction And a side accommodating part is formed at one end of the other side; An end receiving portion is formed at one end in the width direction and the other end; Synthetic rubber-based hot melt adhesive is applied to the back side, and is formed by attaching a release paper on the adhesive; When the construction is coupled to the side receiving portion formed in the adjacent floorboard material pre-installed at the same time, the end projection provided at one end is coupled to the end recess groove provided in the adjacent finishing plate material pre-constructed Disclosed is a floor finishing floorboard comprising an ondol for which a hot melt adhesive adhered to a back surface is simultaneously bonded to a bottom surface.

In addition, according to Korean Patent Laid-Open Publication No. 2001-101827 (floor material consisting of board-like flooring components connected in a vertical direction), it is mainly a flooring material consisting of floorboards having a regular quadrilateral, a quadrilateral, or a versatile shape, The floorboard material is composed of an edge, a horizontal bottom surface and a horizontal top decoration surface, the floorboard is composed of a lower connecting lip (lip) on two adjacent edges, characterized in that the two remaining edges are composed of an upper connecting lip Doing. On the other hand, the lower connecting lip consists of a mainly vertical lower lip face disposed parallel to the nearest edge, and the lower lip face is configured to interact with the mainly vertical upper lip face disposed on the upper connecting lip and thus two connecting adjacencies. The floorboards are locked together in the horizontal direction. In addition, since the connecting lip mainly consists of a horizontal locking surface, it discloses a flooring composed of one or several heels that are snap-connected with a recess that restricts the vertical movement between two connecting adjacent floor plates. Doing.

A common feature of the above cited references is that binding with adjacent floorboards consists of horizontal fastening means and vertical locking means, and it is found that rotation and / or horizontal construction is inevitable in order to establish the binding by these means. Can be. Hereinafter, a description will be given of the technical configuration to which the present invention is disclosed in order to improve the conventional problem, in particular, the constructionability, while explaining the conventional configuration of the conventional floorboard material.

1 is an enlarged cross section of a general floorboard, and in particular, an enlarged configuration of two opposite sides of the floorboard. The floorboard material may be rectangular or square or any other shape, but usually has a length of 1 m, a width of about 10 cm, and a rectangular shape of 0.5 cm to 1.5 cm in thickness. Therefore, in the present specification, when it is necessary to define the direction, the length direction is defined as the direction extending along the length, and the width direction may be understood as the direction extending along the width shorter than the length. The floorboard material is manufactured using the original board with the veneer, HPM or LPM attached on the plywood, solid wood, high density fiber board or particle board, and is suitable for ondol in consideration of thermal properties. A foamed synthetic rubber-based or foamed polypropylene-based hot melt pressure-sensitive adhesive having improved resilience may be attached to the back surface of the floorboard material, and a release paper for maintaining adhesive performance may be attached thereto. 1 is an enlarged configuration of two opposite sides (edges) in the longitudinal direction and / or the width direction. As shown in FIG. 1, a typical floorboard 100 is constructed in which a locking means 120 having fastening means 130 extends along sides in the longitudinal and / or width directions. The locking means is embodied by the protrusions 121 and the grooves 122 having a shape complementary thereto, which are installed in an inclined direction with respect to the adjacent lined floorboard material 100 ′ (see FIG. 2) or are attached to the floorboard. Construction in the horizontal direction with respect to (see Fig. 3), the protrusion 121 is inserted into the adjacent floorboard groove 122 and locked so as not to move in the vertical direction, and thus the fastening means 130 is fastening elements that tightly tighten each other Ie, the protrusions and the locking projections 133 and 134 are snap-fitted to each other so as to be prevented from being separated in the horizontal direction. At this time, when the inclined construction is described in more detail, the two floorboards are inserted into each other by the rotational movement, and one end of the protrusion 121 may be formed as a curved portion so that the rotational movement is smooth. In order for the protrusion 121 to be seated on the upper wall 123 and the lower wall 124 of the groove 122, the horizontal length of the protrusion 121 should be designed to be about the horizontal length of the fastening means in order to sufficiently support the pressure applied from the upper side. However, due to the constant horizontal length that the protrusions should have, construction with adjacent floorboards actually causes the following problems. That is, when attempting to bind the floorboard material to the adjacent floorboard material in the longitudinal direction and / or the width direction, only inclined (rotation) construction and / or horizontal construction is possible, for example, the longitudinal side part is adjacent to the floorboard material. After tightening with, the widthwise side part is fixed when the widthwise side part is fastened with other adjacent floorboards, so the horizontal side part can only be installed horizontally. Since it is established by hitting the opposite side by using a certain tool on the other side, there is a significant inconvenience in the construction, resulting in a low construction efficiency. In addition, the underfloor floorboard material is a material that repeats expansion and contraction by heat transmitted from the bottom of the floor, but in particular, there is a problem that the horizontal separation between the floorboards caused by expansion caused the play between the floorboards. Such a play can be found in the conventional floorboard fastening means are weak.

Accordingly, the present inventors can smoothly fasten when the base and the adjacent floorboards are combined, and attempted various side structural modifications to prevent horizontal deviation between the fastened floorboards, resulting in the present invention.

The present invention has been made in order to solve the problems in the conventional construction as described above, the object of the present invention is a veneer, plywood, wood, high density fiber board (High density Fiber board) or patterned plate (Particle board) on A foamed synthetic rubber-based or foamed polypropylene-based hot melt adhesive prepared by using an HPM or LPM-attached disk, and optionally with improved thermal stability, suitable for ondol, is attached to the back surface of the floorboard and Release paper is attached to maintain the adhesive performance, the protruding portion is formed downward in one side of the longitudinal and / or width direction, the protrusion of the S line is formed on the inner surface of the protrusion, the other side of the groove complementary to the protrusion The upper part is formed upward, but the recess of the S-line which can be seated with the S-line protrusion is designed, so that the floorboard and the floorboard path Direction and / or width of the vertical construction of the interference fit from, in the direction of the side engaged, is prevented from leaving in the horizontal direction, to provide a floor finish floor plate material for granting workability and partial repair and ease of jaesigong.

The present invention is based on plywood, solid wood, high-density fiber board or cut plate, the upper and lower parts of the base plate, the veneer, high pressure melamine laminated board (HPM) or low pressure melamine laminated board (LPM) by cold or hot pressing processing as an integral structure In a floor finishing floorboard material manufactured by using a unit disk that is formed by cutting the original disk to be formed in a predetermined length and width, having a protrusion on one side in the longitudinal direction and / or the width direction and a groove on the other side, And projections in the longitudinal and / or lateral sides are downwardly formed so as to enable vertical construction only in the longitudinal and / or widthwise side fastening of the floorboard material, and grooves in the other side to be co-fitted with the projections are upwardly formed. It is composed. The floorboards fastened by the insertion of the protrusions and the grooves are prevented from being horizontally separated by the underfloor heat.

The present invention is to form a S-line shaped projections on the inner surface of the protrusion to prevent vertical departure of the fastened floorboards, S-shaped recesses and latching jaw is designed on one side of the groove portion to be complementary to this It features.

The present invention is characterized in that the foamed synthetic rubber-based hot melt adhesive is optionally applied to the back surface of the floorboard material, and is formed by attaching a release paper on the adhesive. The foamed hot melt adhesive, which is composed mainly of synthetic rubber, is a non-solvent type adhesive that is harmless to the human body, and its role is to adhere and fix concrete floors and plate-like floorboards having a somewhat rough surface. It can adapt to any deformation that may occur in wood such as shrinkage and expansion according to the heating conditions and moisture content change.In addition, the foamed synthetic rubber-based hot melt adhesive layer absorbs the impact transfer of the floor when walking or Imparting improved sound absorption and sound insulation. In particular, when constructing a floorboard material with an adhesive, problems when the adhesive is adhered to the floor and fastened with adjacent floorboards in the horizontal direction may be solved by the vertical construction according to the present invention.

In the present invention, the term "length direction" refers to a rectangular floorboard material, and is defined as a long axis direction, and the "width direction" defines a short axis direction, but when applied to a square floorboard material, a "length direction" Alternatively, the "width direction" may be understood as one side direction selected from both sides perpendicular to each other. In addition, the "horizontal direction" refers to the horizontal direction with the bottom surface placed on the floor sales, the "vertical direction" refers to the direction set to be perpendicular to the horizontal direction, that is, perpendicular to the floor bottom surface. However, horizontal or vertical is horizontal or vertical to the extent understood by those skilled in the art and does not necessarily mean perfect parallel or perfect right angles.

In the construction of the floorboard member having the above structure, the floorboard member having a protrusion extending in the longitudinal direction with respect to the pre-installed floorboard member groove portion is vertically installed to fasten and fix the floorboard member groove part, in particular, to be attached to the back surface. The hot melt adhesive is adhered to the bottom surface to facilitate adhesion between the floorboards, and at the same time, the protrusions extending in the width direction are vertically aligned with the other floorboard widthwise grooves of the pre-constructed floorboards. When the pressure is applied, the widthwise protrusion and the groove may be clamped by being clamped. This vertical construction is advantageous in comparison with the conventional floorboard material in which the fastening between the widthwise protrusions and the grooves was possible only by horizontal construction, especially in comparison with the conventional floorboard material in which the widthwise fastening construction was inconvenient with the adhesive fixed to the floor. To provide convenience and ease of image.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

The floorboard side configuration according to the present invention can be applied to either the longitudinal or the widthwise direction, preferably constitute the widthwise side, and most preferably constitute the side in both the longitudinal and lateral directions. Can be. In the case where the side structure according to the present invention is applied only in the width direction, the longitudinal side structure can be applied with a conventional fastening structure.

Figure 4 is a schematic cross-sectional view of the floorboard longitudinal and / or widthwise side portion according to the present invention, Figure 5 illustrates a floorboard vertical construction method according to Figure 4, Figure 6 is a construction example of Figure 5 4 is a cross-sectional view illustrating the state in which the floorboards of FIG. 4 are fastened.

The floorboard 200 has fastening means consisting of the protrusions 250 and recesses 251 and locking means consisting of the downward protrusions 221 and complementary grooves 222 extending along the longitudinal and / or widthwise sides thereof. It is configured. At this time, the locking means is an element for preventing the horizontal departure of the floorboard material, the fastening means is a configuration for preventing the vertical departure.

The downward protrusion 221 is complementary to the groove 222, and the protrusion outer surface 226 is inclined inwardly with a slight angle to meet one end of the horizontal protrusion lower surface 261, and the other if the protrusion The ends are curved and inclined vertically inward to extend to the protrusion inner surface 228 to form a curved protrusion 250 surrounded by the lower surface 261 and the inner surface 228. Such a protruding portion is hereinafter referred to as an S-line protruding portion. The inner side surface 228 has the same curvature as the curvature of the protrusion 250 and extends horizontally. The downward protrusions 221 and the grooves 222 are designed to be vertically fastened by interference fit so that an interspace 230 is formed, that is, the protrusions outer surface 226 and the groove vertically inner side surface 227 are not tightly coupled. Thus, a space in which dust residues may be interposed between the fastening floorboards may be formed.

On the other hand, the groove portion 222 is made of a complementary space so that the downward protrusion 221 is inserted by interference fit, the vertical inner surface 227 forming the interspace 230 with the protrusion outer surface 226 is the groove portion The lower surface 226 vertically meets one end, and the other end of the lower surface 226 is curved to be inclined vertically inwardly to form the groove outer surface 229, which is surrounded by the lower surface 262 and the outer surface 229. A recess 251 is formed. This recess 251 will hereinafter be referred to as an S-line recess, in which the S-line protrusion 250 of the downward protrusion will complementarily rest. The outer side surface 229 has the same curvature as the curvature of the recess 251 and extends horizontally to form the locking jaw 234. The locking jaw shape will be referred to as an S-line locking jaw, and after the engagement with the protrusion 221 and the groove 222, the S-line locking jaw is seated and coupled to the recess 251 to the upper portion, that is, to the top. It can function as a blocking element to prevent vertical deviation.

The vertical construction according to the present invention is primarily possible by the structure of the downward protrusion and the complementary groove, but it should be understood that the vertical deviation can be prevented by the S-line protrusion 250 and the S-line latching jaw 234. . In particular, the S-line shape is formed so as to flexibly click coupled while preventing the breakage caused by the collision with the protrusion 250 and the locking projection 234 when the protrusion 221 is fixed to the groove 222. That is, there is an important feature of the present invention in designing the S-line protrusion and the locking jaw in order to achieve the two purposes of preventing vertical departure and vertical click binding.

Floorboard material according to the present invention is characterized in that the construction by the rotational movement is impossible and can be fastened only by vertical construction (see Fig. 5).

Longitudinal and / or widthwise construction of the floorboard according to the present invention, as shown in Figure 5, only vertical binding construction is possible to solve the problem caused by horizontal construction or rotational movement construction pointed out in the prior floorboard Doing. First, when one floor board projection 250 is vertically approached toward the pre-installed adjacent floor board recess 251, the protrusion 250 S line is tangent to the latching jaw 234 S line, but there is a slight pressure at the top. Applying the force, the downward protrusion 221 along the S-line may be click-bound to the groove 222 along the S line. At this time, the protrusion S line can reduce the friction with the groove catching jaw so that the interference fit can be more easily progressed, and also reduce the impact that may occur when elastically pushing the catching jaw 234 backward momentarily. It can be useful. At this time, the locking jaw 234 is slightly bent backward, but may be returned to its original shape as the protrusion 250 is seated in the recess 251. Such vertical fastening is ultimately possible from the configuration of the downward protrusion and the corresponding groove, and the protrusion of the S-line and the corresponding recess structure, and the vertical deviation after the fastening can be achieved by the locking line structure of the S-line. .

A schematic cross sectional view in which a floorboard according to the present invention is fastened is shown in FIG. 6. As described above, the protrusion 221 outer surface 226 need not be completely coincident with the groove 222 inner surface 227, and an interspace 230 may be formed. In addition, the groove rear surface 268 also need not be engaged with the adjacent floorboard counterpart, which forms the play due to horizontal expansion. On the other hand, in the case of the floorboard material having the hot melt adhesive 50 attached to the rear surface, the protrusion part 221 is attached to the groove part 222 provided in the adjacent floorboard material in which the protrusion part 221 is pre-constructed in the longitudinal direction and / or the width direction, and it adheres to the bottom bottom. Construction is completed.

Although the present invention has been described in detail only with respect to the specific and preferred embodiments as described above, it is apparent to those skilled in the art that modifications and changes can be made within the scope of the technical idea of the present invention, and such modifications or changes are the present invention. Will fall within the scope of the claims.
