Description

  The present invention relates to an improved floor board material for floor construction. More specifically, improved floor board material for reinforcing ondol floor construction with sound insulation, which can be smoothly bonded in the width direction with the adjacent floor board material, and has improved workability by the horizontal horizontal click coupling method. It is about.

  In general, a floor board material that can be assembled and formed by forming a deco-shaped protrusion and a concave-shaped home on the side (edge) is often used. . These floorboard materials were very easy to install and could be installed by ordinary engineers. The floor board is generally composed of a surface layer such as lacquer or a laminate board. According to Patent Document 1 disclosed by the present inventor (floor material for floor construction including ondol), in the floor material for floor construction manufactured using the unit original plate, at one side end parallel to the length direction. A side accommodating portion is formed at one side end of the side inserting portion; an end inserting portion is formed at one end parallel to the width direction; an end accommodating portion is formed at the other end; and a synthetic rubber-based hot melt adhesive is formed on the back surface. It is applied and formed by attaching release paper on this adhesive; it is provided at one end at the same time as connecting the side insertion part to the side accommodating part formed in the adjacent floor board previously applied at the time of construction. Further, the end protruding portion is coupled to the end recessed home portion provided on the adjacent floor board material previously constructed. In addition, a floor board material for floor construction including an ondol for which a hot melt adhesive attached to the back surface is simultaneously bonded to the bottom surface is disclosed. The present invention is related to Patent Document 1. Further, according to Patent Document 2 (floor material composed of board-shaped floor components connected in the vertical direction), floor material (flooring material) mainly composed of regular quadrangular, quadrangular, or regular rhombus shaped floor boards is used. The board is composed of an edge, a horizontal lower surface, and a horizontal upper decorative surface. The floorboard has a lower connecting lip on two adjacent edges, and an upper connecting lip on the other two edges. It is characterized by having. On the other hand, the lower connecting lip is composed mainly of a vertical lower lip surface arranged parallel to the nearest edge, so that the lower lip surface interacts with a mainly vertical upper lip surface arranged on the upper connecting lip. It is configured. Thereby, the two connected adjacent floor boards are locked together in the horizontal direction. Also, since the connecting lip is mainly composed of a horizontal locking surface, one or a snap which is snap-connected with a recess that limits the vertical movement between two connected adjacent floorboards or Disclosed is a flooring material consisting of several heels.

  However, the cited invention that discloses the above-mentioned click structure in the width direction avoids structural problems of protrusions and home shapes, that is, physical friction due to the square shape, when the basic floor material and the adjacent floor material are bonded in the width direction. Since the protrusion or home deformation may occur at the time of width direction binding construction, not only the assembly workability is remarkably lowered, but the hook binding method applied at the time of length direction binding construction is In the case of construction on an uneven floor surface, there are problems such as the occurrence of a step between floor boards due to the uneven surface. Further, it has been pointed out that the hot melt adhesive on the back surface of the floor board material cannot sufficiently absorb vibrations and noises and has insufficient sound insulation.

  Therefore, the inventor of the present invention has completed the present invention as a result of trying various side and end structure modifications so as to enable smooth mounting when the basic floor material and the adjacent floor material are joined.

By improving the dimensional stability, which is a fundamental disadvantage of wood, by stabilizing the dimensional change of the wood, it gives the workability with the concrete bottom and the ease of partial repair and re-working, sound insulation and sound absorption It is to provide a floor board material for floor construction including for ondol, which is advantageous for noise reduction by a material feature provided with. In particular, it is to disclose an improved floor board material for soundproofing reinforced floor construction in which an inclined click connection without any structural deformation in the width direction between the floor board material and a horizontal click connection is possible in the length direction.

Means for Solving the Invention

  To achieve the above object, the present invention uses a plywood, log, high-density fiber plate or patterned particle board as a base plate, and a pattern, a high-pressure melamine laminate (HPM) or a low-pressure melamine laminate on the upper and lower portions of the base plate. (LPM) parallel to the length direction in flooring materials for floor construction manufactured using unit original plates formed by cutting an original plate manufactured in an integrated structure through cold or hot press processing into a predetermined length and width One side end has a side insertion portion, and the other side end is formed with an arcuate downward inward bay, and has a side receiving portion having a lower home inclined upward from one point, and a lower protrusion at one end parallel to the width direction. And an end receiving portion having a lower home locked with the lower projection at the other end. Furthermore, a foaming synthetic rubber hot melt adhesive is applied to the back surface, and a release paper is attached to the adhesive body, and the above side insertion part is formed on the adjacent floor board material previously constructed at the time of construction. At the same time, the end insertion portion provided at one end is horizontally click-coupled to the end receiving portion. Moreover, the floor board material for floor constructions including the one for ondol where the hot melt adhesive attached to the back surface is simultaneously bonded to the bottom surface is provided.

  In the present invention, the “length direction” is defined as the major axis direction in a rectangular quadrilateral floor board material, and the “width direction” means the minor axis direction. In addition, “both sides” or “both sides” define both sides parallel to the long direction of the floorboard material, and “both sides” or “both ends” mean both sides parallel to the minor axis direction. . On the other hand, when applied to a regular square floor board, the “length direction” or “width direction” referred to in the present invention is defined as any one side direction selected from both sides perpendicular to each other.

  In the floorboard material of the present invention formed in the above structure, the side insertion portion and the side housing portion formed on both side surfaces are fixed to the floorboard material and the floorboard material that are continuously constructed, and at the same time the back surface The hot-melt pressure-sensitive adhesive adhered to the bottom adheres to the bottom surface and serves to facilitate the close construction between the floor boards. Moreover, the end insertion part and end accommodating part which were formed in the both ends cross section of a floor board material play the role which click-fixes a floor board material and a floor board material in a length direction. In addition, foamable hot melt adhesives based on synthetic rubber are solvent-free adhesives that are harmless to the human body. The role of this adhesive is to bond a concrete floor with a slightly rough surface to a plate-like floor board. Fixed, the floorboard made of wood serves to adapt to any deformation that can occur in the wood due to shrinkage and expansion due to changes in the heating conditions and moisture content of the living environment. In addition, the foamable synthetic rubber-based hot-melt pressure-sensitive adhesive layer absorbs or blocks the impact transmission sound of the floor during walking, thereby improving sound absorption and sound insulation.
