DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure for wooden floor panels to be laid on a floor in a building.

[0002]

2. Description of the Related Art A rectangular laminated veneer laminated material (floor LVL) applied as a floor panel is obtained by aligning a plurality of veneers in a certain direction except for a small number of veneers. It is produced by a process of laminating and bonding in a state of being folded. The floor panel made of a veneer laminate is connected and constructed by a method of arranging a large number of floor panels closely in the vertical and horizontal directions and directly fixing them to a horizontal member such as a large-scale building.

[0003]

The above laminated veneer laminate has a large hygroscopic expansion in the grain direction due to moisture, and the floor panels are laid in a state where a gap of 2 to 3 mm is formed between the floor panels. Because it is necessary, the work of constructing each floor panel while creating a gap with a certain width becomes complicated and the work efficiency deteriorates, and the gap between each floor panel deteriorates the heat insulation and sound insulation. There is a problem to do. Therefore,
It is an object of the present invention to provide a floor panel connection structure capable of improving workability in construction of a wooden floor panel and suppressing a decrease in heat insulation and sound insulation after construction.

[0004]

According to the present invention, there is provided a floor panel connection structure according to the present invention, wherein the edge of the floor panel, in which an engaging ridge protruding to the side is formed over the entire length, is provided with the above-mentioned connection. A first abutment surface formed along the joint ridge and a first relief surface formed along the engagement ridge at a position slightly inside the first abutment surface are provided side by side. Of the edges of the panel, an edge formed along the entire length of the engagement groove to be fitted to the engagement ridge is a second edge formed along the engagement groove.
An abutment surface and a second relief surface formed along the engagement groove at a position slightly inward of the second abutment surface are arranged side by side, and the two floor panels constructed adjacent to each other are attached to the second abutment surface. The first abutment surface and the second abutment surface are in contact with each other, and the first relief surface and the second relief surface are connected to each other with a slit-shaped gap therebetween.

According to the first aspect of the present invention, the engaging ridge formed on the edge of one of the adjacent floor panels and the engaging groove formed on the edge of the other floor panel. And a first abutment surface formed along an engagement ridge on an edge of one floor panel and a second abutment formed along an engagement groove on an edge of the other floor panel. When the two floor panels are constructed in a state where the surfaces abut against each other, the first floor panel is formed along the engagement ridge at an edge of one floor panel at a position slightly inside the first abutting surface. In a state where the relief surface and the second relief surface formed along the engagement groove at a position slightly inside the second abutment surface at the edge of the other floor panel are separated by a slit-shaped gap, Adjacent floor panels are connected. When the laid floor panel expands due to moisture absorption, the portions of the adjacent floor panels near the first butting surface and the portions near the second butting surface are pressed against each other and are respectively compressed and deformed, and the floor panels are compressed by moisture. The expansion deformation is absorbed by the compression deformation behavior near the first and second abutting surfaces and the gap.
