It relates to a deck, and more particularly to a deck plate fastening device capable of cushioning impacts in the vertical and horizontal directions and a deck to which it is applied.

Deck is a structure that is installed on the floor of walkways, hiking trails, rivers, parks, and pensions. The deck is generally composed of a deck plate made of natural wood, synthetic wood, and the like, and a device for connecting the deck plates.

The deck is installed in a place with many outdoor people, such as walkways and hiking trails. The deck installed outdoors is impacted in the vertical direction by the load of pedestrians moving on the deck. In addition, since the deck is mainly installed outdoors, strong impacts in various directions are transmitted to the deck due to disasters such as rain, wind, and earthquake. There is a problem that the deck may be deformed or damaged due to the above-described impacts transmitted to the deck. Since the conventional deck does not have the function of buffering the above-described impact, there is a problem that the deck is easily damaged even with a small impact.

In this regard, Republic of Korea Patent Registration No. 10-1852985 "deck plate fastening device" discloses a deck plate fastening device for preventing deformation of the deck plate. Such a conventional deck plate fastening device forms connection grooves on both sides in the width direction of the deck plate, and connects the deck plates in such a way that a connection portion of the deck plate fastening device is inserted into the connection groove. The deck plate fastening device connecting the two deck plates was inserted into the connecting grooves of two adjacent deck plates, thereby preventing the deck plate from being deformed and lifted. However, such a conventional deck plate is fixedly coupled between the deck plates, there is a problem in that it is not possible to alleviate the impact in the vertical direction and the horizontal direction transmitted to the deck plate.

It is to provide a deck that does not break by alleviating a vertical impact and a horizontal impact applied to the deck. In addition, it is not limited to the above-described technical problems, and another technical problem may be derived from the following description.

Deck plate fastening device according to an embodiment of the present invention is a rectangular plate-shaped body; An insertion connector protruding in a “[” shape from the center of one side of the main body; A plurality of fixed connecting portions protruding in a “[” shape from both corners of the other side of the main body; And a plurality of coupling portions protruding from the upper surface of the main body in an “L” shape and coupling the deck plate fastening device with the deck plate, wherein the insertion connection portion and the fixed connection portion are bent to and coupled to the main body 101 ) Is disposed at a position lower than the portion, the insertion connection is inserted under the other deck plate fastening device adjacent to the deck plate fastening device and between a plurality of fixed connections of the other deck plate fastening device, and the inserted deck plate fastening device The insertion connecting portion of the other deck plate fastening device is spaced apart from the bottom of the main body, so that each of the deck plate fastening device and the other deck plate fastening device independently moves in a vertical direction.

As one side surface of the main body 101 of the deck plate fastening device 10 is formed with a concave 1011 recessed, the deck plate fastening device 10 is coupled to the bottom surface of the deck plate 20 The concave portion 1011 forms a void through which air flows on the bottom surface of the deck plate 20,
Moisture is discharged to the outside by air flowing through the air gap between the concave portion 1011 and the bottom surface of the deck plate 20,
The concave portion 1011 includes a plurality of embossed projections 106 projecting convexly toward the deck plate 20,
The concave portion 1011 of the body 101 of the deck plate fastening device 10 includes an opening 107 through which rainwater and air are discharged,
The opening 107 is disposed between the plurality of embossed projections 106, the impact buffer, characterized in that rainwater is discharged to the outside as the rainwater falling to each embossed projection 106 flows toward the opening 107 Deck with function.
