The present invention relates to a member that is coupled to the lower structure of the deck material, that is, deck fastener (Deck Fastener) and the deck structure using the same to construct a deck material made of wood or synthetic wood, in particular nails, screws ( The head of the screw is not exposed and the deck fastener to compensate for the contraction and expansion of the deck material.

Conventional deck clips and fasteners simply have a simple shape for joining the material to the substructure, which can cause distortion and breakage when the material shrinks and expands due to temperature or humidity changes caused by climate or external factors. Can happen.

Japanese Patent Laid-Open Publication No. 2006-77446 discloses a deck material supporting structure, but differs from the present invention in which an H-type flange is used as a fastener and there is no hollow structure in the flange, and therefore a hollow structure in the T-type fastener.

Japanese Patent Laid-Open No. 1999-280144 discloses a deck structure, but has never been disclosed for the use of a flat plate as a means for fastening the deck and for preventing warping or damage of the deck.

U.S. Patent No. 6314699 discloses a deck system having a deck clip, but does not disclose the hollow structure of the clip and the prevention of warping or breaking of the deck.

The present invention is complementary to the problems of the prior art, having a structure having fluidity to accommodate the contraction and expansion of the deck material in the lower coupling portion deck coupling member that can prevent distortion and damage of the material And to provide a coupling structure of the deck material using the same.

The present invention provides a deck coupling member having a horizontal member coupled to both sides of the adjacent deck material, and a vertical member having a hollow structure therein to achieve the above object.

In the present invention, the vertical member is characterized in that it comprises a bishole formed in the center, and the hollow portion is formed symmetrically around the bishole.

The cross-sectional shape of the hollow part in the present invention is not particularly limited, and may be, for example, elliptical, circular or polygonal.

In the present invention, the hollow portion is characterized in that the expansion and contraction in response to the contraction and expansion of the deck material.

In addition, the present invention includes a deck material having a groove on the side, a vertical member having a bishole and a horizontal member and having a deck coupling member having a hollow portion formed inside the vertical member, both sides of the adjacent deck material It provides an assembly structure of the deck material, characterized in that the horizontal member of the deck coupling member is inserted into the groove.

In the present invention, the deck coupling member is fixed to the joist with a direct coupling bis or nail through the bishole, characterized in that the deck coupling member and the direct coupling bis or nail is concealed from the surface of the deck material.

In the present invention, the locking jaw is formed at the lower end of the side groove of the deck material and the locking groove is formed at the lower portion of the horizontal member of the deck coupling member, thereby increasing the coupling force between the deck material and the deck fastener.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing a coupling structure of the deck material according to the present invention, consisting of a deck material 10 and a fastener 20 for coupling it.

Deck material 10 is made of a material such as wood, synthetic wood, grooves 11 for receiving the fastener 20 is formed on the side.

A locking jaw 12 is formed at a lower end of the side groove to be engaged with the locking groove 25 formed at the bottom of the fastener 20 to increase the coupling force between the deck material 10 and the fastener 20.

The fastener 20 is made of a metal having elasticity, a synthetic resin such as a thermoplastic resin and a thermosetting resin, and the like, and is inserted into the side groove 11 between adjacent deck materials 10 and coupled thereto.

After the deck material 10 and the fastener 20 are assembled, the deck material 10 is fastened to the fastener 20 by using fastening means such as a direct connection vis 30 or a nail through the bishole 23 of the fastener 20. It is fixed to a joist (not shown) installed at the bottom of the).

That is, in the construction method, as shown in FIG. 1, the fastener 20 is inserted into the deck material 10 and fixed with a direct connection vis 30 to the lower joist previously installed. Then, the next deck material 10 may be inserted into the other side of the fastener 20. You can do this by repeating this method.

Since the fastener 20 is installed on the side of the deck material 10, the fastener 20 is concealed by the deck material 10 and is not exposed to the outside, and is directly connected to the fastening screw 30 fixed through the fastener 20. ) Is not exposed, and thus there is no problem of deterioration in appearance due to conventional biscuit exposure.

When the construction using the fastener 20 proposed by the present invention uses a general direct connection screw as in the prior art, but fastening the screw 30 to the fastener 20, so that the deck material 10 is not exposed to the surface, The spacing of the deck material 10 can also be kept constant, and the fastener 20 has a bishole 23 formed therein to facilitate the fastening of the bis 30.

The gap generated between the deck material 10 may be filled using a separate member after fixing the bis 30.

Figure 2 is a perspective view and a bottom view of the deck coupling member according to the first embodiment of the present invention, the fastener 20 is composed of a horizontal member 21 and the vertical member 22 is made of a T-shaped when viewed from one side have.

The horizontal member 21 has a length of a direction inserted into the deck material 10 has a longer rectangular shape, the center is formed with a bishole 23 for accommodating the bis 30.

The vertical member 22 includes a bishole 23 through which the bis 30 penetrates, and may be manufactured integrally with the horizontal member 21.

The vertical member 22 has a pair of hollow portions 24 formed symmetrically about a bishole 23 formed at the center thereof, and the hollow portions 24 contract the deck material 10. Deformation or breakage of the deck material 10 can be prevented while expanding and contracting in response to overexpansion.

That is, the deck fastener 20 of the present invention is formed in a hollow structure to have fluidity in the lower portion, so that when the deck material 10 is expanded, the fastener 20 contracts to prevent breakage, and the deck material 10 is again At the time of contraction, the fastener 20 expands again to maintain the gap.

3 to 5 are a perspective view and a bottom view of a deck coupling member according to another embodiment of the present invention. In FIG. 3, the hollow part 24 is a hexagonal shape, and in the case of FIG. 4, a rhombus shape is illustrated. In this case, as shown in FIG. The hollow portion 24 of the fastener 20 may have various shapes in addition to those shown in FIGS. 2 to 5.

As described above, by using the coupling member of the present invention can prevent distortion and breakage due to the contraction and expansion of the deck material, it is easy to join and dismantle, can overcome the disadvantages of direct fastening of nails, screws, etc. have.
