The present invention relates to a flooring flooring material, and more particularly, to an improved flooring material for ondol floor construction, which enables flexible binding construction in a vertical direction with an adjacent flooring material, thereby improving construction workability.

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 must 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.

Therefore, the present inventors can smoothly fasten when combining the base flooring material and the adjacent flooring material, and as a result of attempting various side structural modifications to prevent horizontal deviation between the fastened floorboards, the present invention has been completed.

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 the veneer on the plywood, wood, high density fiber board (High density Fiber board) or cut plate (Particle board), 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 horizontal means of the fastening means in the longitudinal direction and / or the width direction side is composed of 10 times or more of the horizontal length of the protrusion and the groove portion, and the floorboard and floorboard longitudinal direction and / or width direction Vertical construction is possible in the side fastening, and the height of the vertical locking jaw of the fastening means element is about 1/2 of the thickness of the floorboard material. It is designed to provide a floorboard for floor finishing that prevents the separation in the horizontal direction and imparts workability, partial repair and ease of rework.

The present invention is based on plywood, solid wood, high-density fiberboard 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) through cold or hot pressing processing as an integral structure In a floor finishing floorboard material manufactured by using a unit disk formed by cutting a disk to be produced in a predetermined length and width, the floor board member having a projection and the other side groove portion in the longitudinal direction and / or width direction, And the horizontal means of the fastening means of the longitudinal and / or the widthwise side are 10 times or more of the horizontal length of the protrusion (or the groove) so that vertical construction is possible in the longitudinal and / or widthwise side fastening of the floorboard material. Is set to 10-15 times or more.

The present invention further provides that the height of the vertical locking jaw of the fastening means element is designed to be about 1/2 of the thickness of the floorboard, preferably 1 / 2-1 / 3, to prevent horizontal deviation due to expansion of the floorboards that are fastened. 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 direction horizontal to the floor bottom placed on the floor sale, 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 one-board member floorboard groove portion is rotated or vertically installed to fasten and fix the floorboard member, in particular on the back surface. The attached hot melt adhesive is adhered to the bottom surface to facilitate adhesion between floorboards, and at the same time, the protrusions extending in the width direction are vertically aligned with the other floorboard widthwise grooves pre-constructed so as to be vertically positioned. When pressure is applied, the width can be fixed with the protrusion part groove. The advantages of vertical construction are significant compared to conventional floorboards, where fastening between the widthwise protrusions and grooves was possible only by horizontal construction, especially in comparison with the conventional floorboards where the widthwise fastening was inconvenient with adhesives fixed to the floor. It is to provide convenience in construction.

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 the widthwise side portion according to the present invention, Figures 5 and 6 illustrate the floorboard construction mode according to Figure 4, Figure 7 is in Figure 5 or 6 According to the illustrated construction method is a cross-sectional view showing the state in which the floorboard shown in Figure 4 is fastened.

The floorboard 200 is formed by a fastening means composed of the protrusions 230 and the recesses 251 and a locking means composed of the protrusions 221 and the groove portions 222 extending along the sides in the longitudinal direction and / or the width direction. . The locking means is an element that prevents vertical separation of the floorboard material, and the fastening means is configured to prevent horizontal deviation.

The protrusion 221 is complementary to the groove 222, and the horizontal length of the protrusion, that is, the horizontal length (E) of the upper portion of the protrusion 225 is designed to be about half of the horizontal length (S) of the protrusion inclined surface (241), The angle of the inclined surface 241 is preferably composed of about 50 kPa with respect to the horizontal direction, so that the pressure applied from the top of the floorboard can be received and effectively transmitted to the adjacent floorboard chamfer 240 and the upper surface 225 of the protrusion. . The protrusion 221 and the groove 222 are designed such that an interspace 230 is formed, that is, the protrusion front surface 226 and the groove front surface 227 are not tightly coupled to each other so that dust residues between the fastening floorboards A space may be formed in which the water may be interposed. The protrusion upper surface 225 is seated on the groove upper wall 223, the protrusion inclined surface 241 is bound to the groove chamfer 240 can be prevented upward departure of the protrusion, in particular in the present invention the horizontal length (E) ) Is designed to have a very short length to enable a click by the vertical construction. That is, the horizontal length of the protrusion is designed in a predetermined range in order to achieve two purposes of preventing vertical deviation and vertical click binding. For this purpose, the horizontal length L of the fastening means is 10 times of the horizontal length E of the protrusion. (L> E * 10, L, E need not be an integer), preferably set to 10-15 times or more, such a value should be within a range suitable to achieve the purpose of vertical click binding. This is not restrictive. The inventor produced a floorboard material having an E of 0.5 mm, an S of 1.05 mm, and an L of 7.99 mm.

Floorboard material according to the invention is characterized in that not only vertical construction (see FIG. 5) but also construction by rotational movement (see FIG. 6) is also possible. The construction by the rotational movement is a method of tangentially connecting the lower end of the protrusion front surface 226 to the pre-installed floorboard groove bottom inclined surface 236 and rotating the protrusion 221 downward about this to bind to the groove. The bottom of the floorboard protrusion front surface 226 is characterized by being formed as a curved portion. Due to the shape of the curved portion, a useful rotational movement is possible while alleviating a collision with the groove lower inclined surface 236 contacted during the rotational movement. However, it should be understood that the longitudinal and / or widthwise side structures according to the present invention are, among other things, for realizing the advantages of vertical construction.

The side structure according to the present invention is bound by the fastening means composed of the protrusion 250 and the recess 251 of the complementary shape with the protrusion and the groove is provided to prevent mutual separation in the horizontal direction. As shown in FIG. 4, the protrusion 250 formed between the protrusion lower slope 235 and the upper slope 230 is seated in a recess 251 formed between the groove lower slope 236 and the upper slope 231. And, because of the vertical length (H) of the high locking step 234 made by the groove top inclined surface 231, the protrusion 250 is designed to be separated in the horizontal direction. The locking jaw vertical length (H) is preferably designed to be about half the plate thickness (D), but is not limited to this, and ultimately the extent that vertical or rotational movement is possible without horizontal construction with adjacent floorboards. Vertical length (H) is required. On the other hand, the present inventors have made a number of trial and error for setting the angle of the groove top inclined surface 231, but is preferably designed to 50 ㅀ with respect to the horizontal direction, but is not limited thereto. The present inventors produced and tested the groove upper inclined surface 231 and the vertical length of the locking jaw 234 as described above, as well as being able to completely prevent horizontal movement between the fastened floorboards, as well as binding between floorboards. Flexible vertical construction was possible in. The protrusion 250 in the fastening means may preferably be manufactured in a curved shape, and this shape is smoothly caught by the collision with the groove top inclined surface 231, especially in construction by rotational movement (see FIG. 6). Jaw 234 is advantageous to prevent breakage. In addition, the locking step in the present invention is one side is formed by the groove on the inclined surface 231, the upper surface 260, the other side of the vertical rear surface 261, the upper surface 260 and the rear surface 251 is curved shape There is no need. This is in contrast to the conventional horizontal construction floorboard structure, the present invention is to exclude the horizontal construction between floorboards, it can be seen that only vertical construction or rotational movement construction is set to be possible.

Longitudinal and / or widthwise construction of the floorboard according to the present invention, as shown in Figure 5, can be vertical binding construction. When the floor board protrusion 250 is vertically approached toward the adjacent floor board recess 251, the projecting portion 221 front surface is in contact with the groove chamfer 240, the protrusion along the chamfer slope 222 may be clicked into front surface 227 to be engaged. At this time, the curved portion of the protrusion can reduce the friction with the groove upper inclined surface 231 can not only proceed more easily, but also an impact that can occur when the momentum to push the locking jaw 234 elastically backward Useful for reducing This vertical binding construction is possible because the projected horizontal length (E) is possible from a very short structure compared with the horizontal length (L) of the fastening means, and the projected horizontal length is normally impossible from the structure which is similar to or longer than the horizontal length of the fastening means. something to do. In addition, the longitudinal and / or widthwise construction of the floorboard according to the present invention, as shown in Figure 6 may be a rotational movement binding construction. That is, by contacting the bottom surface of the projected floorboard groove groove lower inclined surface 236 pre-installed the lower end of the projection front surface, and the tangential movement of the tangent to the axis, the projecting portion 221 is pre-constructed finishing plate groove portion 222 ), The protrusion 250 may be flexibly seated in the recess 251 along the steep inclination (about 50 kPa) of the groove top slope. At this time, the locking jaw 234 is elastically bent slightly rearward, may be restored to a complementary shape according to the seating of the projection.

A schematic cross sectional view in which a floorboard according to the present invention is fastened is shown in FIG. 7. As described above, the protrusion 221 front surface 226 need not be completely coincident with the groove 222 front surface 227, and an interspace 260 may be formed. In addition, the groove rear surface 261 also need not be engaged with the adjacent floorboard counterpart, which forms the play caused by the horizontal expansion. On the other hand, in the case of the floorboard material with the hot melt adhesive 50 on the back surface, the protrusion 221 is bound 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, Bonding 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.

Floorboard material according to the present invention has a very short projection horizontal length compared to the horizontal length of the fastening means to enable vertical construction in the longitudinal and / or width direction of the adjacent floorboards, floorboard thickness to prevent the departure by horizontal expansion In contrast to the configuration having a very high locking jaw height, this can solve the problem of construction inefficiency pointed out in the conventional horizontal and / or rotational movement construction process. In particular, in relation to the construction of the floorboard material to which the foamable hot melt adhesive with resilience is applied, the floorboard material capable of vertical construction according to the present invention has the effect of being able to complete the construction very efficiently since it can be simultaneously bonded to the floor surface. will be.
