By fitting a female tongue to the male tongue for pairing, the screw is covered and concealed by the female tongue, thereby suppressing swelling and contraction of a wooden material caused by moisture contained in the air. A notch 5 is formed on the male tongue for clearly indicating a position of screwing the screw, enhancing work efficiency, and preventing a damage to a decorative veneer due to slipping of the screw while screwing. A protrusion 17 and a notch 18 are provided, for enhancing fitting strength.SELECTED DRAWING: Figure 3

Description

  The present invention relates to a floor board for laying wide floors such as gymnasiums, auditoriums, fitness, sports clubs, and multipurpose halls.

Technical background

  Conventionally, this kind of floor board is constructed by applying an adhesive to the base plywood, and usually stretching the nails diagonally from the top of the ridge to the joist, applying the adhesive to the base plywood, It is used for floor board construction such as special upholstery or hidden special sticking that drills holes and penetrates the base plywood through the holes and screws the cerebral screws to the joists.

  In the construction method of ordinary floor boards, joists are attached in parallel at regular intervals so as to be orthogonal to the pulling. Then, place the base plywood on the joists and drive screws or nails into the joists from the base plywood. Next, an adhesive is applied to the base plywood, and a floor board such as that shown in FIG. 5 is laid on the base plywood. After that, the female fruit is inserted into the male fruit held by the nail, and the male fruit is driven in the same manner. Repeat these steps and stretch the floorboard. See Figure 5

  For specially-tensioned floorboards, a single floorboard is stretched by applying an adhesive on the base plywood. Then, the nail 10 is struck diagonally from the male as in the ordinary tension method, and fixed. Then, the second sheet is stretched in such a manner that the male side of the long side of the second floor board is fitted to the female side of the long side of the first floor board already laid. Similarly, the floorboards are laid down on the entire surface, connected vertically and horizontally. Next, in order to maintain a sufficient adhesion state on the adhesion surface, a large number of screw screws 9 are screwed or driven into nails from the floor board to the joists 7. For this purpose, first, inking is performed at an accurate position on the joist where the screw 9 is to be screwed, and dowel holes are formed at a plurality of positions along the inking. Then, screw screws 9 are screwed into the joists from each dowel hole to firmly fix the floor board. After fixing the entire surface, clean the dowel holes. Thereafter, the dowel 12 coated with the adhesive is embedded in the dowel hole. Alternatively, the dowel 12 is embedded after pouring an adhesive into the dowel hole. Then, polish with a drum sander. Polishing requires a plurality of processes such as roughing, intermediate coating, and finishing. Then, it is finished through cleaning, undercoating, polishing, intermediate coating, coating line drawing, and top coating. See FIG.

  Hidden specially-bonded floorboards are formed in a rectangular shape throughout the floorboard, with semi-circular male cross sections along one long side and one short side, and the remaining long and short sides. A cross section in which the male is fitted is provided with a semicircular female fruit, and a protruding part 2 that protrudes horizontally with a constant width is provided below the groove, and the long side provided with the protruding line has a protruding line on the long side. Use a floorboard with a notch that fits in. Adhesive is applied to a base plywood laid on a large number of joists, and one floor board is installed so as to cross the joists. A screw screw 9 is screwed in so that the base plywood is penetrated into the projecting portion 2 projecting the lower part of the female fruit of the installed floor board and the joist is fixed. Insert the ridge of the next floor board into the groove of the fixed floor board, and repeatedly fix the projecting part 2 to the joist under the groove with screw screws or the like in the same way as the first sheet, and stretch the floor board. See FIG.

Problems to be solved by the invention

  The conventional slab and groove shape of the floor board is not strong enough to hold the floor board because it has a shape that can only be nailed diagonally to the ridge as described in the normal tension. In addition, the floorboard is made of wood, so it is greatly affected by the moisture content, and when it is installed in a wide gymnasium, the floorboard is greatly affected by the expansion and contraction due to the humidity in the air. In the special tension method that has been changed, complicated work such as drilling holes in the surface of the floor board and screwing them, and closing the holes that were drilled earlier with dowels reduces workability and increases work time and labor costs. The floor plate of the hidden special sticking method that tried to improve them was made by lengthening the lower part of the groove, screwing it to the joist with a screw screw, and fitting the first groove with the second protrusion. The head of the screw is concealed and it is beautiful in design, shortening the work time and labor cost, but the position where the floor plate is screwed is about 1/3 of the thickness of the whole floor plate, so it will be applied to the floor plate or other holding power It has the problem that it is inferior to a floor board.

Means for solving the problem

  In order to solve the above-mentioned problem, the floor board is formed in a rectangular shape, and one long side is provided with a rectangular protrusion 1 having a rounded tip at the lower part of the floor board, and the protrusion 1 is a lower protrusion 2. And the upper ridge portion 3, and the lower ridge portion 2 and the upper ridge portion 3 have a certain width for screwing the screw screw 9 vertically, and the upper ridge portion 3 of the ridge is lower. A groove 4 in which the protrusion 1 is fitted is provided on one long side which is longer than the protrusion 2 and the rectangular protrusion having a rounded tip is provided on one short side. A groove into which the above-mentioned ridge is fitted is provided on the short side that is paired with the side, and a floor plate is formed by bonding a decorative veneer on the surface of the floor plate, and the lower ridge portion of the ridge 1 of this floor material By providing a certain width for screwing screw screws into 2 and the upper ridge part 3, the ridge 1 of the floor board becomes thick, so that the actual strength of the floor board can be increased. Come.

  And the workability is improved by determining the position when screw screw 9 is screwed in by using the floor plate in which notch 5 is inserted in parallel with the long side at the top of ridge 1 provided on one long side of the floor plate. In addition, damage to the veneer 6 and the like due to sliding of screws is eliminated. Furthermore, the adhesive strength is increased by passing through the base plywood from the ridge 1 and fixing the joist to the joist, thereby suppressing expansion and contraction due to the influence of moisture drifting in the air of the wood. Further, when the pair of grooves 4 is fitted to the protrusions 1, the screw screws 9 screwed into the protrusions 1 are covered with the grooves 4.

  Furthermore, by providing the notch part 18 which becomes a pair with the protrusion part 17, the protrusion part and groove | channel for a combination increase and the further fitting part can be strengthened.

The structure of the floor board according to the present invention will be described with reference to FIG.
The floor board has a rectangular shape, and one long side is provided with a rectangular ridge with a rounded tip at the bottom of the floor board, and the ridge 1 is fixed for screwing screw screws 9 vertically from the top to the bottom. The upper portion of the ridge is provided with a ridge portion 3 that is longer than the lower portion 2 and protrudes horizontally with a constant width, and the upper ridge of the ridge 1 is formed on one long side of the pair. A groove 4 is provided in which the strip 3 is fitted. A notch is formed on the lower side of the groove 4 so that the lower projection 2 is aligned with the end green, and one short side has a rounded tip. A rectangular ridge centered on the center of the thickness of the cage is provided, a groove on which the ridge is fitted is provided on the short side that is paired with the short side, and a decorative veneer is provided on the surface of the floor plate. Or a floor plate in which a notch 5 is cut in parallel with the long side at the top of the ridge 1 provided on the long side of the floor plate, or one long side The long sides of the a provided pair ridges 17 on the 4 side is a floor plate having a cutout portion 18 which protrusions 17 are fitted.

  For construction using this floor board, for example, as shown in FIGS. 2 is a three-dimensional view of the entire construction, FIG. 3 is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 4 is a cross-sectional view taken along the line BB in FIG.

  First, a plurality of joists 8 are installed on the large guide 11 so as to be orthogonal to the large guide 11, and screw screws 9 are screwed and fixed from the joist 8 to the large guide 11. Next, a base plywood (discarded plywood) 7 is laid on the assembled joists 8, and screws or nails are driven from the base ply into the joists and fixed. Adhesive is applied to the fixed base plywood, and a single floor board is placed so as to be perpendicular to the joists 8. Here, the base ply is pierced with a screw screw 9 from the top of the notch 5 provided on the ridge 1 to the joist 8. At this time, the screw screw 9 is notched so that the head of the screw screw 9 is flush with the surface of the ridge 1 and the screw screw 9 does not slip or does not hit the decorative veneer 6 when the screw screw 9 is screwed. Type in from the top of 5.

  Then, when the long side groove 4 of the second floor board is fitted to the long side protrusion 1 of the first floor board, the first protrusion 1 becomes the groove 4 of the second floor board. It will be in the state of fitting. Thereafter, the screw screw 9 is screwed into the notch 5 of the second protrusion 1 in the same manner as the first sheet. Then, a plurality of floor boards are laid side by side so as to be perpendicular to the joists 8. In the vertical direction, the installation and the fixing with the screw screw 9 are repeated while being fitted into the short side groove 14 of the adjacent floor plate to the short side protrusion 13 of the floor plate. In this way, the entire construction is completed.

  In addition, it can also be constructed in such a way that it is directly fixed to the joists without using the base plywood and then laid down.

Effect of the invention

  According to the present invention, the solidity of the floorboard is thickened by providing a constant width in the lower ridge portion 2 and the upper ridge portion 3 in order to screw the screw screws into the floorboard's male fruit and the lower part of the flooring material. Therefore, the actual strength of the flooring is increased. Furthermore, since the screw screw 9 is screwed to the joist through the base plywood from the ridge 1, the adhesion strength is increased, and the expansion and contraction due to the influence of moisture drifting in the air of the wood is suppressed.

  Further, since the screw 9 is screwed from the ridge 1 to the joist, the holding force against the intense vibration and shaking in the vertical direction is greatly improved. And, it is not necessary to make holes on the surface of the floor board during construction, and screw screws 9 are screwed to the joists to pass through the base plywood from the floor board, so that the screws are fixed when the base plywood is laid on the joists. The work can be reduced more than before, and the construction time is shortened and the labor cost is reduced accordingly.

  By combining the groove 4 which becomes the mating surface of the ridge 1, the screw screw head embedded in the notch 5 does not come out on the surface and has the effect of being finished beautifully in design. By inserting a notch 5 into the ridge 1 into which the screw screw is screwed in, the position of the screw fastening is clarified, and the phenomenon that the screw slips when screwing in the screw screw can be prevented and screwed in accurately. It also eliminates damage to the decorative material at the top of the floor board when screwed.
