Description

  The present invention relates to actual bonding of building board materials. More specifically, the present invention relates to a real structure used when a male real part and a female real part provided on a wooden building board are actually coupled.

Conventionally, with regard to the joining of wooden building boards such as floor boards and wall boards, a male part and a female part that can be fitted to each other are provided on opposite end faces of the veneer. It is generally performed to join a plurality of single plates by actually connecting a female fruit of a female fruit part. For example, the following patent document describes an actual connection composed of a male real part 61 and a female real part 62 shown in FIG.
JP-A-8-109734 (pages 1-4, 2, 3, 4)

  Usually, in the actual connection, the male real part 61 is fixed to a base material such as a trunk edge, and the female real part 62 is actually connected. That is, in FIG. 4 of the present application, the base portion of the upper vertical surface of the base end where the male part 611 of the male part 61 protrudes is set as a nail driving part 612, and a nail is applied to this part by an automatic nail driver or the like. A nail is driven in, and then the female fruit 621 is joined. However, when nailing, there is a problem that the tip of the nail escapes and is difficult to drive, and the entire male part 61 bulges after driving. Therefore, the present invention provides a plate material for construction that can be driven with a nailing machine or the like with good workability, and that can prevent a poor fitting due to wood swelling and can firmly connect a male part and a female part. The problem is to provide an actual structure of

In order to solve the above problems, the present invention takes the following technical means. In other words, according to the present invention, the male body includes a male body part and a female body part, and the male body protrudes in a real connection in which the male body of the male body part fits into the female body of the female body part. A bulge absorbing groove portion is recessed in the upper vertical surface of the end portion, and a base portion on the surface side of the male body is notched at the base end portion where the male body protrudes to form a nail driving groove portion. As a result, the lower vertical portion of the upper vertical surface is expanded by a depth corresponding to the depth of the nail driving groove and the nail is driven into the nail driving groove. An actual structure of a building board material is provided in which the bulge is absorbed into the groove for absorbing the bulge of the same tree .

It is preferable that the wood swelling absorbing groove portion is inclined so that the ceiling portion becomes lower as it goes deeper, and the groove portion has a substantially right-angled triangular cross section. In addition, it is preferable that a base portion on the surface side of the male body is cut into a V shape at the base end portion where the male body protrudes to form a nail driving groove. Furthermore, it is preferable that the lower corner portion of the protrusion on the upper part of the female real part is chamfered to form a nail head accommodating part.

The invention according to claim 1 is as described above, and in particular, a wood swelling absorbing groove portion is recessed in the upper vertical surface of the base end portion on which the male fruit projects, and the male fruit projects. The base portion on the surface side of the same male and female at the base end portion is cut out to form a nail driving groove, so that the lower part of the upper vertical surface of the wood swelling absorbing groove is the nail driving groove. Since it extends downward by the depth, so that the blister caused by the nail being driven into the nail driving groove is absorbed into the puff absorbing groove, so that the tip of the nail escapes. It is possible to nail firmly without the need to absorb the blisters generated during nailing and prevent a poor fitting, and the male part and the female part can be firmly coupled.

  The wood swelling absorbing groove portion is obliquely arranged so that the ceiling portion becomes lower as it goes into the depth, and has a substantially right-angled cross section, so that the wood swelling can be released laterally and The thickness of the upper part of the protruding base end part remains, and the strength can be maintained.

At the base end where the male projectingly protrudes, the base on the surface side of the male is cut out to form a V-shaped nail driving groove, which can be used as a guide when nailing. In addition, the tip of the nail can be applied to the nail groove and the nail can be driven with good workability by an automatic nail driver or the like.

  In addition, since the lower corner portion of the protrusion on the upper part of the female body of the female body part is chamfered to form a nail head storage part, the head of the nail that has been driven into the nail driving groove part is stored, And the female body can be firmly fitted.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing the actual structure of a building board according to the present invention. As can be seen from FIG. 1, the actual structure is composed of a male real part 1 and a female real part 2, and the male fruit 11 of the male real part 1 is fitted to the female fruit 21 of the female real part 2 for construction. Plate members, for example, end portions of plywood are joined together to form a floor plate, a wall plate or the like.

  In the embodiment of the present invention, as shown in FIG. 1, the base end upper vertical surface 12 on which the male fruit 11 protrudes is provided with a tree swelling absorbing groove portion 13 for absorbing the wood swelling generated when nailing. Is provided. Further, as can be clearly understood from FIG. 1, the above-mentioned tree swelling absorbing groove portion 13 is obliquely arranged so that the ceiling portion becomes lower as it goes into the depth, and has a substantially right-angled cross section. That is, the expansion of the wood part is escaped as much as possible into the groove 13 for absorbing the swelling of the wood, and the thickness of the upper vertical surface 12 of the base end part is left, so that the strength of the male part 1 is maintained.

  In addition, the base of the upper vertical surface 12 of the base end portion on which the male fruit 11 is projected is used as a guide when nailing, and a V-shaped so that the tip of the nail does not escape and can be firmly nailed. A notch of the mold is provided to form a nail driving groove 14. Further, the lower corner portion of the upper projection 22 of the female fruit 21 is chamfered to form a nail head storage portion 23 for storing the nail head.

  FIG. 2 is an explanatory diagram showing a state in which the nail 3 is applied to the nail driving groove 14 and the nail 3 is driven using the automatic nailing machine 5. FIG. 3 is a cross-sectional view showing a state where the nail 3 is driven in this manner to fix the male real part 1 to the base material 4 and the real female part 2 is actually coupled. The male part 1 is fixed to the base material 4 by the nail 3 and the wood swelling is absorbed into the wood swelling absorbing groove 13 and the head of the nail 3 is housed in the nail head storage part 23 and is firmly actually joined. It is clear that As can be seen from FIG. 3, the female fruit 21 is formed with some allowance. Therefore, when an actual bonding is performed using an adhesive, this extra space is used as an adhesive reservoir.

It is sectional drawing which shows the actual structure of the board | plate material for construction concerning this invention. It is explanatory drawing which shows the state which drives a nail into the nail-groove part concerning this invention. It is sectional drawing which shows the state actually couple | bonded using the actual structure of this invention. It is sectional drawing which shows a well-known real coupling | bonding.
