In the process of stitching 10 and fixing it to the base frame 30, the lower sides of the first and second vertical portions 12 and 12a divided into two sides based on the elastic cut portions 16 are respectively elastic cut portions. (16) serves to provide an elastic force that can be smoothly moved or restored to its original state.

At this time, the locking groove 15 may be installed in one place, but the conventional synthetic wood deck 20 is not constant even in the precision manufacturing, the thickness is not constant, and the thickness deviation occurs as the thickness of the synthetic wood deck 20 is caught Only when the position of the groove 15 is changed, smooth coupling with the base frame 30 is possible.

Therefore, the present invention in view of such a situation that the engaging groove 15 is formed by a plurality of continuous up and down in succession to any one of the locking groove 15 selectively in accordance with the thickness change of the synthetic wood deck 20 As the locking projection 32 of the frame 30 is caught, a smooth binding state can be maintained.

That is, the present invention can smoothly bind even in the case of a synthetic wood deck 20 having a thin thickness t1 as shown in FIG. 5, as well as a synthetic wood deck 20 having a thick thickness t2 as shown in FIG. 7. The locking projections 32 of the base frame 30 are selectively caught in any one of the locking grooves 15 in accordance with the thickness change of the synthetic wood deck 20, thereby providing an effect of maintaining a solid binding state.

On the other hand, the synthetic wood deck 20 applied to the present invention is formed on the upper surface 21 of the non-slip groove 22 of the mountain form at equal intervals, but is not limited to this, the lower surface 23 of the semi-circular non-slip projections 24 ) Is formed continuously to prevent the sliding smoothly, as well as having a different shape according to the user's taste or selection, while changing the position of the lower surface (21, 23) synthetic wood deck (20) It can be installed to further expand the user's choice, and provides the effect to provide a variety of designs.

In addition, even when the positions of the upper and lower surfaces 21 and 23 are changed, the multi-couplers 10 are respectively provided on both sides of the upper and lower surfaces 21 and 23 so as to enable a smooth engagement with the multi-coupler 10 at all times. An indentation surface 25 on which the upper plate portions 13 and 13a of the upper surface is formed is formed, and the indentation surface 25 into which the engagement protrusions 14 and 14a of the multi coupler 10 can be fitted. ) Are formed respectively.

The base frame 30 which serves to stably support the synthetic wood deck 20 in a cross state is made of a conventional rectangular tube cross-sectional shape, but the center of the upper surface of the first and second of the multi-coupler 10 A coupler insertion portion 31 into which the two vertical portions 12 and 12a are inserted is formed to penetrate up and down along the longitudinal direction, and the upper surfaces of both sides except the coupler insertion portion 31 are formed of the multi-coupler 10. While engaging the locking groove 15 to form a locking projection 32 to maintain the binding force.

4 and 5, when the multi-coupler 10 is sewn between the adjacent synthetic wood decks 20 as shown in FIGS. 4 and 5, the binding protrusions 14 and 14a on both sides are inserted into the synthetic wood deck 20. While each of which is inserted into the 26, the synthetic wood deck 20 is integrally bound to each other, and at the same time, the first and second vertical portions 12 and 12a are obstacles in the process of being inserted into the coupler inserting portion 31. When the machine 32 is engaged with any one of the recesses 15, the multi coupler 10 and the base frame 30 are integrally bound to each other, thereby consolidating and binding the composite wood deck 20 and the base frame 30 to each other. It becomes possible.

Therefore, while providing the effect that can be installed very quickly and easily the composite wood deck 20, while significantly improving the irrationality according to the use and piece work of the direct connection as in the prior art by reducing the number of work dramatically reduced construction cost It provides a special effect to further improve the work quality.

In addition, the present invention is the first, second vertical portion 12 (12a) directly when the need to detach the multi-coupler 10 constructed in order to partially replace, maintain the synthetic wood deck 20 The front and rear surfaces of the multi-coupler 10 can be detached while retracting the house using a separate tong tool or the like.
