Description

  The present invention relates to a flooring joining structure in which ends of flooring are joined on a base material such as a slab.

Conventionally, various techniques have been known for the joining structure of floor materials. For example, in Patent Document 1 below, a floor board having a predetermined standard and a joining member having a substantially U-shaped cross section for joining adjacent floor boards to each other, A floorboard joining unit is disclosed. This joining unit is formed in a groove shape in which protruding ends that are erected on both sides of the U-shaped joining member are formed at predetermined intervals along both sides of the long side of the floor plate, and the bottom is a taper shape. It is made to fit so that the floor boards adjacent to this fitting part may join, and a floor surface is formed.
No. 3059410 (pages 1 and 2, Fig. 1)

  However, when the floorboards are joined using the joining unit described in Patent Document 1, it is difficult to prevent lifting, but it is not always satisfactory. The present invention solves such problems, and firmly joins the ends of floor materials such as floorboards to prevent lifting, and can be easily and easily constructed on a base material with a workability. The issue is to provide

In order to solve the above problems, the following technical means are taken in the present invention. That is, according to the present invention, a floor material and a joining member that joins end portions of adjacent floor materials are formed, and V-shaped grooves having a substantially V-shaped cross section are formed on both ends of the bottom layer of the floor material. The bottom layers of the side portions facing each other of the floor material are cut into a corner shape to form an engagement recess, and the joining member is integrally formed from a synthetic resin having elasticity. are those made up of a base portion where the hook-shaped engaging pieces bent inward is extended at both ends, a pair of elastic engagement portion provided upright on a substantially central portion of the base portion, the elastic engagement Locking protrusions that engage with the engaging recesses are extended to the outside at the joint portions, and a locking groove portion that locks a locking claw portion of the hook-shaped engagement piece is formed on the V-shaped groove. An internally installed flooring joining structure is provided. The joining member is preferably formed from a synthetic resin such as polypropylene.

  The said joining member is good also as a short length so that the edge part of an adjacent flooring may be joined at a suitable space | interval along a length direction. Or it is good also as a long length which joins the edge part of an adjacent flooring material over the full length.

  In addition, a mating convex portion is provided on one joint surface of the adjacent floor material, and a mating concave portion is provided on the other joint surface so that actual coupling is possible. May be joined.

  The invention according to claim 1 is as described above, and the pair of elastic engaging portions erected at a substantially central portion of the base portion of the joining member includes the bottom layers of the side portions facing each other of the flooring. A hook-like engagement piece extending at both ends of the base portion of the joining member is engraved on both end sides of the bottom layer of the flooring material. Since it engages elastically with the V-shaped groove having a substantially V-shaped cross section and engages at two places in this way, it is possible to prevent the floating and firmly join adjacent flooring materials. Further, since a clicking sound is generated when elastically engaging, it is possible to easily confirm the completion of joining and to perform construction with good workability.

  The joining member is short so that the end portions of the adjacent flooring can be joined at appropriate intervals along the length direction, and the interval can be adjusted according to the construction site, so the manufacturing cost of the joining member can be reduced. At the same time, the workability of construction can be improved.

  A fitting convex part is provided on one joining surface of the adjacent flooring material, and a fitting concave part is provided on the other joining surface to enable actual coupling, and in addition to joining by the joining member, actual joining is performed to join the flooring material. Therefore, it is possible to prevent the lifting and join the floor materials more firmly.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a partial cross-sectional side view showing a state in which a flooring joint structure A according to the present invention is applied to a base material 4. FIG. 2 is an exploded side view showing the flooring joining structure A shown in FIG. As shown in FIG. 1 and FIG. 2, the flooring joint structure A of the present invention comprises a flooring 1 and a joining member 2 for joining the ends of the flooring 1 adjacent to each other. The joining member 2 has substantially the same length as the flooring 1. A V-shaped groove 11 having a substantially V-shaped cross section is formed on the end portion side of the bottom layer of the flooring 1, and the bottom layers of the side portions facing each other are cut out into a corner shape to form an engagement recess 12. ing. Reference numeral 3 in FIG. 1 indicates an elastic sheet body having substantially the same thickness as the base portion 21 of the joining member 2, and keeps the flooring 1 stably and horizontally on the base material 4 together with the joining member 2.

  The joining member 2 is integrally formed from a synthetic resin having elasticity, and includes a base portion 21 and a pair of elastic engagement portions 22 erected at a substantially central portion of the base portion 21, and this elastic engagement portion A locking projection 221 is extended on the outer side of each of the 22. Further, hook-shaped engaging pieces 23 are extended at both ends of the base portion 21, and the end portions of the hook-shaped engaging pieces 23 are locking claw portions 231. The V-shaped groove 11 is further provided with a locking groove 111, and the locking claw 231 of the hook-shaped engagement piece 23 is locked to the locking groove 111.

  FIG. 3 is an explanatory view showing a method of joining adjacent flooring materials 1 using the joining member 2. As shown in FIG. 3, the joining member 2 is previously fixed to the base material 4 by a known method such as a screw, an adhesive, or a double-sided tape, and the elastic engaging portion 22 and the hook-like engaging piece 23 of the fixed joining member 2 are fixed. Next, the engaging recess 12 and the V-shaped groove 11 of the flooring 1 are respectively fitted. As described above, since the joining member 2 is integrally formed from a synthetic resin having elasticity, the pair of elastic engagement portions 22 are pushed by the bottom corners of the flooring 1 and are mutually connected as shown in FIG. The locking protrusion 221 engages with the engaging recess 12. Similarly, the hooking claw portion 231 of the hook-like engagement piece 23 is also elastically displaced and engages with the hooking groove portion 111 provided in the V-shaped groove 11, and in both cases, a clicking sound is generated. As shown in FIG.

  FIG. 4 shows a flooring joint structure A according to the present invention in which a mating convex portion 13 is provided on one joint surface of adjacent flooring 1 and a mating concave portion 14 is provided on the other and both are joined by actual coupling. It is a partial cross section side view shown. As shown in FIG. 4, it is clear that the floor materials 1 can be more firmly joined to each other because they are actually joined in addition to the floor material joining structure A.

It is a partial cross section side view which shows the state which constructed the joining structure of the flooring concerning this invention. It is a decomposition | disassembly side view which shows the joining structure of the flooring shown in FIG. It is explanatory drawing which shows the method of joining the adjacent flooring using the joining member of this invention. It is a partial cross section side view which shows the state which actually joined and joined the flooring in addition to the joining structure of the flooring concerning this invention.
