Description

[Detailed explanation of the invention] (Purpose of the invention) In the installation of architectural floor panels with connecting edge plates attached to the outer periphery of the back surface, even if there are slight variations in the dimensions of the chamfering applied to the side edges of the floor panels, it is possible to The present invention relates to a free floor having a cutout that facilitates connection.

(Prior art) In order to lay architectural floor panels, connecting edge plates are attached in advance to the outer periphery of the back surface of the floor panel, and a part of the edge plates protrudes outward to form an engaging part, which is arranged in a conventional manner. Utility Model Publication No. 53-26842 No. 1, No. 2,
There is no problem in the case of butt connection as shown in Figure 3, but when a decorative panel is stretched on the top surface and a free floor with vertical and horizontal chamfering is fitted and connected on the side edges, the chamfering dimensions are Unless the precision is extremely high, there will be large variations in the thickness of the decorative board, so the positions of the female and male corners will be misaligned and it will not be possible to fit them together, or even if they are forced to fit together, there will be a difference in the surface, which will need to be chamfered. Not only is it unseemly to have to make corrections, but the yield rate is low and uneconomical as parts that cannot be fitted are discarded. Furthermore, in order to facilitate fitting and connection, the adhesive surface of the engaging portion protruding outward from the connecting edge plate is cut down slightly to release the entire surface, which results in poor adhesion and, therefore, the adhesive effect of the adhesive material. If it was insufficient, the degree of adhesion to the floor deteriorated and the strength was insufficient, resulting in "floor noise".
This invention solves these problems and allows easy connection even if there is some variation in the dimensions of the actual panes without causing any "floor noise."

(Structure of the device) This device solves the above problems by cutting out a part of the upper surface of the engaging portion of the connecting edge plate.Hereinafter, one embodiment of this device will be explained based on the drawings. .

FIG. 1 is a perspective view of the free floor 1, and FIG. 2 is a side sectional view thereof. An engagement part is formed by protruding along the front and left side edges of the free floor 1 which has a female tongue 3 formed on the lower end of the decorative board 2, and a cutout part 4 is recessed along the side edge on the upper surface of the free floor 1. Attach the connecting edge plate 5 and the auxiliary connecting edge plate 6, and then attach the connecting edge plate 5.
A mounting frame 7 made of synthetic resin is screwed onto the back surface of the frame 7 at appropriate intervals, and an adjustment support leg 9 fitted into the central spiral portion 8 of the mounting frame 7 is provided through a through hole drilled in the connecting edge plate 5. A hollow adjustable support leg 9 made of synthetic resin that can be rotated through the support leg 12 to adjust its height can be erected on the floor surface 10 to form a flat bed. Figure 3 is a plan view of a free floor, where the right side and far side edges that are not shown in the perspective view of Figure 1 are machined to have male tongues 11. Formed so as to fit and connect to the side edge. FIG. 4 is a side view showing the male tongue 11 and female tongue 3 on the side edges. Now, in order to easily connect the interlocking fitting at the time of installation in question, even if there are some variations in the dimensions of the actual groove machining, Fig. 1, Fig. 2, and Fig. 3.
The notch 4 shown in the figure can be recessed in the connecting edge plate 5 with a depth of about 1 mm and a width of 30 to 40 mm, so that there is no difference in the adhesion between the mating floor and the upper surface of the connecting edge plate. It can be pressed tightly without any problem.

(Effects of the invention) Since this invention has the above configuration, it has the following advantages.

(1) Even if there is some variation in the dimensions of the floor grooves, they can be easily connected, which eliminates the need for highly accurate grooves and improves yield.

(2) Since the adhesive surface is flush with the bottom surface of the decorative board, highly accurate adhesion is possible, which prevents the phenomenon of "floor noise" after flooring.

(3) Adhesive precision is good, so the strength is sufficient.

Claims (1)

[Scope of utility model registration request] A connecting edge plate 5 and an auxiliary connecting edge plate 6 are attached vertically and horizontally to the outer periphery of the back surface of the decorative board 2, and a part thereof protrudes outward to form an engaging part, so that when a free floor is arranged and laid, adjacent floors are attached. In the configuration in which the side edges are fitted and connected, the female tongue 3 is placed on the upper surface of the connecting edge plate 5 and the auxiliary connecting edge plate 6 that protrude along the side edge edges of the processed decorative board 2, This free floor is characterized in that a notch 4 with a width of approximately several centimeters and a slight depth of approximately 1 to 2 mm is recessed in contact with the outer peripheral edge of a decorative board 2.
