Description

  The present invention relates to an assembling-type resin mud, and more particularly to an assembling-type resin mud having a fitting structure, an adhesive gel layer provided on the bottom surface of a surface layer, and a gap capable of absorbing expansion and contraction due to heat.

  As a conventional assembly type resin mud, for example, “FLOOR PLANK” in US Pat. No. 7,155,871 of Patent Document 1 has been proposed. As shown in FIG. 1, such an assembly type resin mud has an upper layer plate 1 that is an elongated plate and a bottom layer plate 2 that has the same dimensions as the upper layer plate 1, and an adhesive gel layer is formed on the bottom layer plate 2. 3 is provided, and the upper layer plate 1 and the bottom layer plate 2 are adhered by the adhesive gel layer 3.

  However, in the conventional assembly type resin mud, since the long side and the short side are aligned and no fitting structure is provided, when an external force is applied in the horizontal direction, each assembly type resin mud is separated separately. There has been a problem that sliding and deformation due to heat cannot be prevented.

  The conventional assembly type resin mud does not have a fitting structure at the periphery, so it cannot be positioned cleanly, and in order to improve the overall appearance, the dimensions of the place where the assembly type resin mud is placed are precisely It is necessary to measure, and it takes a lot of man-hours.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
First, reference will be made to FIGS. The assembly type resin mud of the present embodiment includes a base layer 10 and a wood grain surface layer 20.

  The base layer 10 is formed into an elongated piece-like wood floor board, and includes a long left side 11, a short upper side 12, a long right side 13, and a short lower side 14. The protrusion 111 is provided at a certain distance, and a plurality of fitting recesses 131 corresponding to the protrusion 111 are provided on the long right side 13.

  The wood grain surface layer 20 is formed into an elongated piece-like wood floor board, and its length and width are the same as those obtained by removing the protrusions 111 of the base layer 10, and an adhesive gel layer 21 is provided on the bottom surface thereof. Can be adhered to the upper surface of the base layer 10, and the protrusion 111 is held in a state protruding from the periphery of the grain surface layer 20, and is exposed as it is at a position corresponding to the fitting recess 131 of the base layer 10 of the adhesive gel layer 21. . In the assembly-type resin mud A of the present embodiment, all the connecting portions of the side edges and all the protrusions 111 and the fitting recesses 131 have gaps S that can absorb expansion and contraction due to heat. The gap S can prevent deformation due to heat.

  As shown in FIG. 3, the assembly type resin mud A of the present embodiment is exposed as it is at a portion corresponding to the fitting recess 131 of the base layer 10 of the adhesive gel layer 21. Accordingly, when another assembly type resin mud A is combined with the side of the assembly type resin mud A, the protrusion 111 of the other assembly type resin mud A is positioned on the adhesive gel layer 21 of the assembly type resin mud A. The adhesive gel layer 21 is adhered.

  In the assembly type resin mud A of this embodiment, the grain surface layer 20 is formed into an elongated piece-like wood floor board, and the base layer 10 is formed into an elongated piece-like wood floor board, and the dimensions are almost the same as the grain surface layer 20. However, a plurality of protrusions 111 are provided at a distance from the long left side 11, and a plurality of fitting recesses 131 corresponding to the protrusions 111 are provided at the long right side 13. An adhesive gel layer 21 is provided on the bottom surface of the wood grain surface layer 20, and the adhesive gel layer 21 can adhere the wood grain surface layer 20 to the upper surface of the base layer 10, and the protrusion 111 is held in a state protruding from the periphery of the wood grain surface layer 20. Is done. When the assembly type resin mud A of the present embodiment is combined, the assembly 111 can be stably fixed by fitting the projection 111 and the fitting recess 131 between the assembly type resin muds A together. All of the connected portions of the side edges and all the protrusions 111 and the fitting recesses 131 have a gap S that can absorb expansion and contraction due to heat, and the gap S can prevent deformation due to heat.

(Second embodiment)
The base layer 10 is provided with a plurality of protrusions 121 on its short upper side 12 and a plurality of fitting recesses 141 corresponding to the protrusions 121 on its short lower side 14.

  When combining the assembly type resin mud A of the present embodiment, the projection 121 and the fitting recess 141 of the assembly type resin mud A are fitted together, and another assembly type resin mud is attached to the projection 121 of the assembly type resin mud A. When the adhesive layer 21 of A is adhered, the assembly type resin mud A can be stably fixed.

  Since the conventional assembly type resin mud is not provided with a fitting structure at the periphery, it cannot be positioned cleanly. According to the assembly type resin mud A of the present invention, the protrusion 121 and the fitting recess 141 Therefore, when the protrusion 121 and the fitting recess 141 are fitted, the assembly type resin mud A can be fixed stably, and the overall appearance is improved.

  The present invention can be applied to a resin mud.
