In general, decks made of natural wood, synthetic wood, and recently, aluminum are widely used as flooring materials installed on hiking trails, walking trails in parks, around lakes, and indoor floors.

Flooring made of natural wood or synthetic wood gives pedestrians an eco-friendly aesthetic and visually comfortable feeling with beautiful patterns and soft texture unique to wood, and a deck made of aluminum gives an urban feel and a very concise feeling. give Therefore, there is a tendency to construct the deck appropriately in consideration of the material of the deck according to the site conditions.

In order to form flooring using decks, decks must be installed adjacent to each other. Conventionally, after constructing a concrete foundation on the floor where the deck is installed, a plurality of joists are attached to the concrete foundation with anchor bolts in a certain form. After fixing and installing, as shown in FIG. 1a), after prefabricated fitting of the deck board 110 on the joist, construction of combining and fixing the joist and the deck board using a fixing means 111 such as a bolt or a direct connection piece. method has been mainly used.

By the way, in the prior art as described above, it consists of a structure in which screws or bolts are fastened obliquely to the outer surface of the deck in a state where the deck is inserted to fix the clip together with the deck to the frame, and the installation is very difficult, so there are relatively many There was a problem that required time and manpower. In addition, when the deck is disassembled for repair or maintenance during use after the construction of the deck is completed, since the entire deck must be disassembled one by one, repair and maintenance due to a large amount of disassembly and reinstallation have been very inconvenient. In addition, due to the characteristics of each deck material, there is a problem in that the deck is warped, deformed, or damaged due to contraction/expansion caused by moisture and heat.

Hereinafter, an elastic clip for fixing a deck according to the present invention and a construction method of a deck using the same will be described in detail with reference to the accompanying drawings.

In the present invention, the elastic clip for fixing the deck refers to a pair of decks facing each other as well as being fixed to the joist when the decks having transverse insertion grooves formed on both sides are installed on the joist arranged side by side in the longitudinal direction. Refers to an elastic clip for fixing on top.

In the present invention, the work of constructing the deck is made elastically and conveniently, so that the installation is simple and the deck can be completely prevented from being damaged by the direct connection piece, and even when deformation such as contraction or expansion due to factors such as weather occurs, It is a technical feature that a continuous pressing force is exerted to ensure a stable fixing force.

2 and 3 are exemplary views of an elastic clip for fixing a deck according to an embodiment of the present invention.

First, the elastic clip 100 for fixing the deck can secure strength, prevent corrosion, and can be made of a material having a predetermined elasticity. For example, the elastic clip 100 for fixing the deck may be made of a metal material, preferably a stainless steel material.

Next, the elastic clip 100 for fixing the deck includes a seating portion 110 disposed above the joist 10 .

The seating portion 110 is formed in a plate-like shape having a predetermined area so as to sufficiently secure a contact area with the joist, for example, it may be formed in a rectangular shape as shown in FIG. 2 .

In addition, one or two or more fastening holes 111 are formed through the mounting part 110 so that it is fastened to the joist 10 through a fastener (not shown) such as a direct connection piece.

In addition, when the seating part 110 is disposed between the pair of decks 20 seated on the joists 10, its bottom surface is spaced apart from the joists 10 by a predetermined distance, which is the fastening hole 111 ) When fastening to the joist 10 by inserting a fastener from the top to the bottom to penetrate the joist 10, the seating portion 110 is forcibly lowered by the step between the seating portion 110 and the joist 10, which will be described later. It is to press the deck downward in a state in which the first elastic pressing portion and the second elastic pressing portion are inserted into the transverse insertion groove.

Next, the present invention includes a pair of extensions 120 extending upwardly outward from both sides of the seating portion.

The extension part 120 forms both side walls of the elastic clip for fixing the deck, and is a member that is in close contact with the side surface between the bottom surface of the deck 20 and the transverse insertion groove 21 .

Preferably, the extension portion 120 is formed extending in an arc shape in a round shape, and the side surface between the bottom surface of the deck 20 and the transverse insertion groove 21 in close contact with the extension portion corresponds to the extension portion A round surface 22 may be formed.

When the extension part 120 and the round surface 22 of the deck are mutually round, when the deck 20 contracts or expands in the longitudinal direction due to the influence of weather, it is more firmly engaged with each other on the tangential surface. Provides resistance to contraction or expansion of the deck.

In addition, when the mounting part 110 is fixed to the joist 10 with a fastener such as a direct connection piece, the head of the fastener presses the inner circumferential surface on both sides of the extension part 120 in the process of descending in the direction of the joist. As the extension part 120 is engaged more firmly with the round surface 22, the first elastic pressing part and the second elastic pressing part, which will be described later, are elastically pressed into the transverse insertion groove 21.

In the case of the prior art, as shown in FIGS. 1c) and 1d), the side surface between the bottom surface of the deck and the transverse insertion groove is simply made in a vertical form, and the first and second bent portions of reference numerals 13 and 14 in FIG. 1c) , And the member in contact with the vertical side of the deck, such as the elastic piece of reference numeral 200 in FIG.

Here, if the deck shrinks due to factors such as weather, the bent portion of reference numeral 13 in FIG. 1c) and the elastic piece of reference numeral 200 in FIG. Since it is a structure without a structure, it was not possible to prevent the behavior of the deck due to play when an external force in the horizontal direction acts. Due to this behavior, safety accidents such as slipping may occur when pedestrians pass on the deck, so the deformed deck had to be replaced with a new deck. That is, the conventional deck fixing clip has a problem in that a lot of manpower, time, and cost are generated for maintenance.

In contrast, the present invention prevents behavior due to play even when deformation such as contraction or expansion occurs in the deck due to factors such as weather through the rounded arc-shaped extension 120 and the corresponding round surface 22 Since it can be done, it is possible to further secure the life of the deck compared to the prior art, and there is a remarkable effect that manpower, time, and cost for maintenance can be reduced.

Next, the present invention includes a first elastic pressing portion 130 and a second elastic pressing portion 140 inserted into the transverse insertion groove 21 of the deck.

First, the first elastic pressing portion 130 is a member that is bent outwardly from the upper edge of the extension portion to be inserted into the transverse insertion groove 21 of the deck and protrudes.

Preferably, the first elastic pressing portion 130 includes a first bent portion 131 that is bent and extended from the end of the extension portion 120 in an arc shape so that the end is inclined downward, and the first bent portion It may include a first contact portion 132 bent in the horizontal direction from the end.

Here, when the first bent part 131 is inserted into the transverse insertion groove 21, the outer circumferential surface of the upper surface is pressed by the upper surface of the transverse insertion groove to give elastic force to the first contact part 132, 1 contact part 132 is the bottom surface of the transverse insertion groove 21 by the elastic force acting by the first bent portion 131 in a state in which the bottom surface abuts against the bottom surface of the transverse insertion groove 21 It holds the deck more firmly while pressurizing it elastically.

When the deck 20 contracts or expands in the vertical direction through the first bent part 131 and the first contact part 132, the first elastic pressing part 130 flexibly responds and holds the deck while moving. By giving it, the behavior caused by the play is prevented.

Next, the second elastic pressing part 140 according to the present invention is formed side by side on the side surface of the first elastic pressing part, is bent outwardly from the upper edge of the extension part and protrudes, and the first elastic pressing part 140 protrudes outwardly. It is a member that is inserted into the transverse insertion groove 21 of the deck together with the portion 130.

The second elastic pressing part 140 is formed bent in an arc shape from the end of the extension part 120 so that the end is inclined upward, and the end in the transverse insertion groove 21 is the first bent part 131 It includes a second bent part 141 disposed higher and a second contact part 142 bent downward from an end of the second bent part 141 .

When the second elastic pressing portion 140 is inserted into the transverse insertion groove 21 of the deck from the side, the boundary between the second bent portion 141 and the second contact portion 142 is the upper surface of the transverse insertion groove. Guided to be inserted more smoothly and resiliently while being pressed by, and when the deck 20 contracts or expands, the second bent portion 141 and the second contact portion 142 of the transverse insertion groove where the boundary abuts. It is firmly attached to the upper surface and elastically supports the deck to prevent movement due to play.

Preferably, the boundary between the second bent part 141 and the second contact part 142 can secure a contact area with the upper surface of the transverse insertion groove 21, and when in contact with each other, sharp corners It is good to have a rounded arc shape to prevent the deck from being damaged by

In the case of the clip of FIG. 1d), the pressing piece of reference numeral 300 only contacts the bottom surface of the transverse insertion groove inside the transverse insertion groove, but is completely separated from the upper surface of the transverse insertion groove, so contraction or expansion occurs If this occurs, when the upper part of the transverse insertion groove is moved downward by contraction, it is simply seated on the upper surface of the pressing piece, and the lower part is spaced apart from the elastic piece of reference numeral 200, so that a gap can be formed between them. As the deck moves in vertical and horizontal directions, it can be separated from the clip.

In the present invention, when the deck 20 expands, as shown in reference numeral (a) in FIG. 4, the rounded extension 120 touches the round surface 22 of the deck to resist expansion of the deck 20, , As shown in reference numerals (b) and (c), the first elastic pressing portion 130 and the second elastic pressing portion 140 move in a fluid manner in the transverse insertion groove 21 and resist expansion. do

Conversely, when the deck 20 contracts, as shown in (a) of FIG. 5, the extension 120 supports the round surface in a state in contact with the round surface 22 to provide resistance to contraction, As shown in reference numeral (b), the second elastic pressing portion 140 prevents the upper side of the transverse insertion groove of the deck from being pressed down and adheres more firmly to the transverse insertion groove at the same time. In addition, as shown in reference numeral (c), the first elastic pressing portion 130 elastically presses the bottom surface of the transverse insertion groove while holding the deck 20 floating upward.

In addition, in the present invention, an incision 150 vertically incised by a predetermined depth is formed along the boundary of the first elastic pressing part and the second elastic pressing part, so that the first elastic pressing part and the second elastic pressing part can be separated. . The incision 150 maximizes the force for pressing the bottom and top surfaces of the transverse insertion groove when the first elastic pressing portion 130 and the second elastic pressing portion 140 are inserted into the transverse insertion groove. Gives you the flexibility to do it.

Meanwhile, in the present invention, as shown in FIGS. 7 and 8, one second elastic pressing part 140 may be provided only on one side of the first elastic pressing part 130, and as shown in FIGS. 2 and 3, the first elastic pressing part 140 may be provided. A pair of second elastic pressing parts may be provided on both sides of the second elastic pressing part, or a pair of second elastic pressing parts may be provided on both sides of the first elastic pressing part. In the elastic clip shown in FIG. 2, one second elastic pressing part 140 is formed on the left and right sides, and a pair of first elastic pressing parts 130 are formed on both sides thereof, and the first elastic pressing part and A cutout 150 is formed between the second elastic pressing parts.
If the second elastic pressing part 140 is provided only on one side of the first elastic pressing part 130, the second elastic pressing part 140 faces each other at each corner of one extension part and the other extension part. As shown in FIG. 7 , the first elastic pressing part 130 and the second elastic pressing part 140 may be disposed in a form of crossing each other.

Next, the present invention may include a non-slip rubber bar 200 that closes the space 101 inside the elastic clip for fixing the deck formed by the seating portion and the extensions on both sides.

The non-slip rubber bar 200 is a member that passes vertically between the decks from top to bottom and is force-fitted into the space 101, and may be made of a material having elasticity, for example, a rubber material, , It may be formed in a length corresponding to the deck fixing elastic clip or may have a predetermined length so as to be intermittently fitted in the form of connecting a plurality of deck fixing elastic clips.

In addition, the non-slip rubber bar 200 has a first body portion 201 having a corresponding shape so as to be inserted into the space portion 101 inside the elastic clip for fixing the deck, as shown in FIG. 9, and the first body It extends upward from the part and may include a second body portion 202 formed of a corresponding shape to fill the space between the pair of decks 20 disposed on both sides of the elastic clip for fixing the deck.

In addition, the non-slip rubber bar 200 is installed on the elastic clip 100 for fixing the deck, when a pedestrian passes over the second body part 202 exposed between the decks 20 and 20 Anti-slip parts 210 such as concavo-convex or protrusions may be formed on the outer circumferential surface of the upper end of the second body part 202 to prevent slipping. The shape of the non-slip portion 210 in FIG. 9 is only an example to help understanding of the present invention, and is not limited to the scope of the present invention.

On the other hand, since the first body portion 201 has a larger volume than the second body portion 202, it is compressed to reduce the volume, and then forcibly inserted between the decks 20 and 20 to pass through the first body portion 201. When the body part 210 enters the space part 101, it is preferable to restore it to its original state. Accordingly, a contraction induction hole 220 may be formed in the central portion of the first body portion 201 along the longitudinal direction. The contraction induction hole 220 may be formed in one or two or more as needed, and may have an appropriate diameter.

In the case of some prior art, a synthetic resin filler having waterproof performance is injected into the space inside the elastic clip for fixing the deck, but since such a filler is difficult to remove once cured, maintenance and repair such as cracks or damage of the deck are required. In this case, there may be many difficulties in removing the filler, and there is a problem that is not economical because a huge construction cost is generated. In contrast, the present invention has the effect of enabling easy removal and replacement after construction by applying the non-slip rubber bar 200, which is inexpensive to manufacture, and significantly reducing the construction cost.

In addition, in the present invention, the non-slip rubber bar 200 may be installed on each elastic clip 100 for fixing the deck or may be arranged at regular intervals for smooth drainage. For example, as shown in FIG. 10, the non-slip rubber bar 200 is installed at regular intervals (eg, stride) along the other direction based on the deck at one end, so that a large amount of rain falls, such as during the rainy season. It is also possible to prevent pedestrians from slipping while ensuring smooth drainage. In addition, since the amount of use of the non-slip rubber bar 200 can be reduced, the effect of reducing the construction cost can also be expected.
