The present invention relates to an assembly structure of deck material and a deck fastener used for the assembly.

In general, in the construction of the deck, as shown in FIG. 1, the lower joist 2 is installed, and the deck material 1 (wood or synthetic wood) is directly connected to the joist 2 (or nails). Fasten with).

At this time, when the head of the vis 3 is exposed on the deck material 1 surface and the fastening interval and the line of the vis 3 do not match, the appearance quality is significantly degraded. In addition, when fixed with the direct connection (3) there is a fear that the deck material 1 is deformed and damaged while the deck material 1 shrinks and expands after construction.

U.S. Patent No. 661398 discloses a decking assembly and kit having a hold-down clip, but the hollow structure of the present invention prevents deformation due to contraction and expansion of the deckboard. Has not been disclosed.

U.S. Pat.No.7052200 discloses a deck board fastener having a compression element formed at both ends to correspond to the contraction and expansion of the deckboard. The structure is different from the present invention.

Accordingly, it is an object of the present invention to provide a deck fastener and an assembly structure of deck materials using the same, which is easy to construct and does not expose direct connection bis, and prevents deformation of deck materials.

In order to achieve the above object, the present invention provides a deck fastener having a vertical member having a bishole for receiving a vis and a horizontal member inserted into a side of an adjacent deck material.

In the present invention, the horizontal member has a bishole formed in the center and wings formed in an arc shape on both sides thereof, in particular, a hollow portion is formed in the wing, and the hollow portion of the wing expands in response to the contraction and expansion of the deck material. And shrink.

In addition, the present invention comprises a deck material having a groove on the side, a vertical member having a bishole and a horizontal member, the deck fastener is formed on both sides of the horizontal member arcuate wings are formed, the hollow is formed on the wings, It provides a deck material assembly structure characterized in that the horizontal member of the deck fastener is inserted into both side grooves of the adjacent deck material.

In the present invention, the deck fastener is fixed to the joist with a straight screw or nail through the bishole, characterized in that the deck fastener and the straight screw or nail is concealed from the surface of the deck material.

The present invention can be more easily installed deck using a fastener made of synthetic resin material, and can compensate for problems such as deformation and breakage of materials after construction.

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

1 is a cross-sectional view showing a conventional deck material assembly structure, when the construction of the prior art when the head of the bis (3) is exposed to the surface of the deck material (1), when fastening several screws (3) If the spacing of the screws 3 and the lines of the screws 3 do not match, the appearance quality is very poor. In addition, when the deck material (1) and the lower joist (2) is directly connected to each other when the coefficient of thermal expansion between the two materials (for example, the deck material (1) is wood or synthetic wood, the lower joist (2) is steel (Steel) ), When the deck material 1 shrinks or expands due to moisture and heat, it may cause distortion or breakage of the deck material 1.

Figure 2 is a cross-sectional view showing a deck material assembly structure 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.

The fastener 20 is made of a material such as synthetic resin, it is coupled to the side grooves 11 between the adjacent deck material 10 and coupled.

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. 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.

3 and 4 are a plan view and a side view of the deck fastener according to the present invention, respectively, the fastener 20 is composed of a vertical member 21 and a horizontal member 22 is composed of a T-shaped when viewed from one side.

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

The horizontal member 22 is formed in a substantially rectangular shape having a longer length in the direction of insertion into the deck material 10, and a bishole 23 for accommodating the bis 30 is formed at the center thereof.

Wings 24 are formed at both sides of the horizontal member 22 in the longitudinal direction, and the wings 24 are formed in an arc shape and are easily inserted when inserted into the deck material 10.

Wings 24 are formed in the hollow portion 25, while the hollow portion 25 is inflated and contracted in response to the contraction and expansion of the deck material 10, to prevent deformation or breakage of the deck material 10 Can be.

That is, by forming the wings 24 on both sides to absorb the shrinkage / expansion in the fastener 20, even if the deck material 10 increases and decreases after construction, there is no problem such as damage or deformation of the deck material 10. none. The contraction / expansion absorbing wing 24 having the hollow portion 25 is pressed when the deck material 10 is stretched, and then returns to its original state when the material is reduced.

In the case of US Patent No. 7042200, the contraction / expansion absorption structure is remarkably different from the present invention. Specifically, in the case of the first US patent, the compression element is formed by protruding a separate component from the top plate. On the other hand, in the case of the present invention, the shrinkage / expansion absorbing wing is formed to extend integrally with the horizontal member, and the structure is simple, so that the production is easy. Second, in the case of the US patent, the compression element is not inserted into the slot of the deck board, but in the present invention, the shrinkage / expansion absorbing wing is inserted into the side groove of the deck material together with the horizontal member. Third, although the compression element is formed on the unidirectional side of the fastener in the US patent, the shrinkage / expansion absorbing wing is formed on the long side of the fastener in the present invention.

The present invention by using the deck-only fastener made of synthetic resin in the construction of the deck, the appearance is beautiful compared to the prior art, can be easily installed, and also by damage / expansion and contraction of the material that can occur after construction and We suggest the construction structure of the deck to compensate for the deformation.
