It relates to a fastening structure comprising a fastening member and a joist made of the fixing member and a wood deck.

As industrialization and urbanization intensify, the desire for a pleasant living environment is intensifying. As a result, there are increasing cases of creating trails or hiking trails around residential complexes.

 Wood decks are mainly used for road pavement such as trails due to the nature-friendly feeling of wood and excellent cushioning ability. The construction of the walkway using the wood deck is made by fixing the joist on the floor in the form of a train rail, and then speaking the wood deck.

However, while the wood deck has the above advantages, there is a disadvantage that the durability is inherent in the wood. In other words, the contraction and expansion is repeated according to humidity or sunlight, and as a result, deformation or cracking occurs as time passes, and the maintenance cost is increased due to frequent maintenance replacement. To prevent or delay this problem, synthetic wood with high moisture resistance is used, or reinforcement to prevent deformation is inserted into the wood.

According to the prior art of Fig. 1b, a symmetrical fastener 6 is provided so that the fixing member 4 can be inserted and fixed at the same time in the fixing groove 5 of the neighboring wooden deck 1, and the wooden deck 1 is It is made possible to speak on the joist (7).

However, since the place where the fixing member 4 is not inserted among the fixing grooves 5 is constructed in a hollow state, there is a problem that the hollow portion can be easily broken. That is, as the walking is repeated by the pedestrians, the place where the fixing member is not inserted is continuously damaged and is damaged, so that durability is poor and aesthetics are not good, and thus reconstruction is inevitable.

In addition, both ends of the longitudinal direction of the wood deck (1) is fixed on the joist (7), the center is the stress to be deformed by the escape of moisture in the wood, the stress due to the contraction and expansion of wood according to the climate and the vertical load of the pedestrian By this, the fixing member 4 at both ends is subjected to a force lifted upward by the bending phenomenon of the wood deck 1. Therefore, by repeatedly receiving the stress (forces) causing the deformation of the wood as described above, the problem that the fixing between the fixing member 4 and the joist 7 can be loosened.

In addition, the reinforcing material (3) can suppress the bending phenomenon as described above, to prevent the loosening of the fixing member to some extent, there is a problem that the construction cost increases as a separate fixing member is required during construction.

In addition, the manufacturing method of the fixing member 10 may use an extrusion method suitable for the production of beam shape having a complicated cross section.

Figure 3 is a schematic diagram showing a bending phenomenon prevention function of the wooden deck fastening member according to the present invention. As shown in Figures 2 and 3, the vertical plate 14, the upper projection piece 11, the lower projection piece 12 and the binding projection piece 13 of the fixing member 10 is a wooden deck 20 It is fixed in the longitudinal direction on both sides of the upper side of the wood deck 20 to correspond to the upper projection piece 11, the lower projection piece 12 and the binding projection piece 13 of the fixing member 21, the lower groove 22 and the binding groove 23 are formed in the longitudinal direction, respectively. The upper protrusion piece protruding to one side in the horizontal direction from the upper end of the vertical plate of the fixing member is inserted and coupled to the upper groove 21 of the wooden deck, and the upper protrusion piece from the lower end of the vertical plate of the fixing member The first protrusion 12a protruding in the same direction is inserted and coupled to the lower groove 22 of the wood deck, and the vertical plate between the upper protrusion 11 and the lower protrusion 12 of the fixing member. The binding projection piece 13 formed to protrude in the same direction as the direction in which the upper projection piece 11 and the first projection portion 12a protrude from 14 is inserted into and coupled to the binding groove 23 of the wooden deck to make it a wooden deck. The fastening member is formed. The vertical plate 14, the upper projection piece 11, the lower projection piece 12 and the binding projection piece 13 forming the fixing member of the present invention are formed to have the same cross-section in the longitudinal direction, the upper projection piece The lower protrusion piece and the binding protrusion piece are fixed to the upper groove 21, the lower groove 22, and the binding groove 23 of the wood deck, respectively. Therefore, the fixing of the fixing member 10 is in the form of fixing both sides of the width direction of the wood deck 20 to the joist 50, the deformation of the wood deck 20 is prevented. In addition, the bending resistance is enhanced by the metal and the cross-sectional shape of the fixing member 10, thereby having an effect of suppressing the bending phenomenon of the wooden deck 20 due to the pedestrian load. Therefore, the bending of the wood deck 20 is prevented, so that the load applied to the fastening means to be described later can be blocked and the loosening of the fixing member 10 can be prevented.

Figure 4 is a cross-sectional view showing a wooden deck fixing member according to the present invention. As shown in Figure 2 and 4, the upper projection piece 11 in addition to the above functions to protect the upper edge of the wooden deck 20, to prevent the edge breakage to improve the durability of the wooden deck 20 It plays a role.

The lower protrusion piece 12 further includes a bent part 12c protruding upward from an end of the second protrusion part 12b, wherein the bent part 12c is provided with a neighboring bent part 12c. By being engaged by the clasp 30 to be described later, the wood deck 20 can be spoken on the joist 50.

The bent portion 12c may be formed to protrude vertically upward with respect to the second protrusion 12b or bent to be inclined at an inclination angle α in a range of 0 to 45 ° with respect to the vertical direction. This facilitates the coupling and fixing operation when fixing the coupling member such as a screw to the joist after placing the clasp 30 on the bent portion 12c located between the narrow gaps of the adjacent wood deck 20. To make it work. However, when the inclination angle α is excessively large, the binding force between the bent portion 12c and the clasp piece 30 may be lowered. Therefore, the inclination angle α is inclined in the range of 5 to 25 degrees with respect to the vertical direction. By making the bending protrusion with α), the coupling and fixing work can be facilitated and the binding force between the bending portion and the clasp piece can be maintained.

The binding projection piece 13 has a projection angle θ in the range of 5 to 45 ° in which the vertical length d of the cross section becomes longer in the protruding direction, which is fixed from the wooden deck 20 to the fixing member 10. While preventing the separation, to further strengthen the bending prevention of the wood deck (20). However, when the protrusion angle θ is maintained too large, since the inlet 24 of the wood deck 20 may be fragile and damaged, the protrusion angle θ may be formed in a range of 10 to 30 °. As a result, the strength of the wood deck and the maintenance of the binding force between the wood deck and the fixing member may be satisfied together.

Further, the protrusion length L of the binding protrusion piece 13 of the present invention is formed to be 1.5 to 3 times longer than the protrusion length l of the first protrusion 12a of the upper protrusion piece 11 or the lower protrusion piece. The binding force between the fixing member and the wood deck can be maintained stably.

The protruding length l of the first protruding portion 12a of the upper protruding piece 11 or the lower protruding piece may protrude from 1/30 to 1/20 of the width W of the wood deck. If the protruding length (l) protrudes less than 1/30 of the width of the wood deck (W), it is not easy to prevent the protection and bending of the wood deck, and if protruding more than 1/20, the protection of the wood deck and The warpage phenomenon can be prevented, but the manufacturing cost of the fixing member and the processing cost of the wooden deck are increased, which is not preferable.
