One side surface of the vertical connector 520b in the width direction may correspond to a smooth vertical surface. Therefore, when the first deck connecting member 500a or the second deck connecting member 500b is installed at the side end of the deck structure in the width direction, the side end surface can be smoothed, so the deck structure Ease of construction can be improved because there is no need to install a separate finishing member at the side end in the width direction.

[Basic structure of deck structure]

1 is a perspective view showing a state in which a yoke is installed on the foundation to install the deck structure of the present invention, and FIG. 2 is a perspective view showing a state in which joists are installed on the yoke of FIG. 3 is a perspective view showing a state in which a deck is installed using a deck connection member on the joists of FIG. 2;

1 to 3, in the deck structure according to an embodiment of the present invention, the yoke 20, the joist 30, and the deck 40 are stacked and installed on the foundation 10 so that they cross each other It can be.

First, as shown in FIG. 1, the yoke 20 may be installed on the base portion 10 that has undergone a flattening process. In an embodiment of the present invention, the yoke 20 is exemplified as being, for example, a metal square tube. However, the material or shape of the yoke 20 is not necessarily limited thereto.

A plurality of yokes 20, as shown in Figure 1, are spaced apart at equal intervals to the side and may be arranged and installed side by side.

Next, as shown in FIG. 2, a joist 30 may be installed on the yoke 20. In an embodiment of the present invention, the joist 30 is exemplified as being, for example, a metal square tube. However, the material or shape of the joist is not necessarily limited thereto. The joists 30 are also spaced apart at equal intervals to the side and may be arranged side by side and installed. The joist 30 may be installed more densely than the yoke, and may be constructed as a square pipe having a smaller cross-sectional area than the yoke. Joists may be installed on the yoke 20 in a direction orthogonal to the yoke 20 .

A deck 40 is installed on the joists 30. For example, the deck 40 may be made of flat and long wood, and the deck 40 may be arranged and installed in a direction orthogonal to the joists 30. The distance between adjacent decks 40 may be about 2 mm to about 5 mm. One deck 40 may be arranged across a plurality of joists 30 adjacent to each other. That is, one deck 40 may be supported by a plurality of joists 30 disposed on its bottom surface.

As a part for fixing the deck 40 to the joist, in the present invention, the deck connection member 500 may be installed. Specifically, the plurality of deck connection members 500 may be provided side by side on the joists 40. In addition, as shown in Figure 3, the finishing member (R) may be installed at the side end of the width direction of the deck structure.

[Structure of deck and deck connecting member]

4 is a front view of FIG. 3, and FIG. 5 is a perspective view showing a state in which a portion of FIG. 3 is enlarged and a portion of the deck is removed.

Referring to Figures 4 and 5, the upper surface of the deck 40 may be formed with grooves coupled to the deformation preventing portion 530 to be described later at both ends in the width direction. However, it is not limited to this configuration. Therefore, a groove may not be formed on the upper surface of the deck 40 .

In addition, the deck connection member 500 includes a base part 510, a vertical connection part 520, a deformation prevention part 530, a first support part 540, a second support part 550, a first coupling part 560 and It may be configured to include a second coupling part 570.

At this time, the deck connection member 500 may be separated into a first deck connection member 500a and a second deck connection member 500b, which will be described later in this regard.

Hereinafter, unless otherwise specified, it is assumed that the deck connection member 500 is configured by integrally combining the first deck connection member 500a and the second deck connection member 500b.

Therefore, the base portion 510 of the deck connection member 500 means that the first base portion 510a and the second base portion 510b are integrally coupled, and the vertical connection portion 520 is the first vertical connection portion ( 520a) and the second vertical connector 520b are integrally coupled. In addition, the deformation preventing portion 530 means that the first deformation preventing portion 530a and the second deformation preventing portion 530b are integrally coupled, and the first support portion 540 includes one side support portion 540a and the other side support portion 540a. This means that the branch 540b is integrally combined.

The base portion 510 may extend from the lower portion of the deck 40 along the longitudinal direction of the deck 40 . In addition, the base portion 510 may be disposed on top of the joists 30 and may have a plate shape.

A second coupling part 570 may be formed at the other end of the base part 510 in the width direction.

Accordingly, the second coupling portion 570 coupled to the first coupling portion 560 of the adjacent deck connecting member 500 can be easily formed at low cost with a simple configuration.

In addition, since the base portion 510 can stably support the second coupling portion 570, the first coupling portion 560 of the deck connecting member 500 adjacent to the second coupling portion 570 is coupled. At this time, it is possible to prevent the second coupling part 570 from being damaged or being pushed to one side in the width direction. Therefore, since the deck connecting members 500 adjacent to each other can be stably coupled and aligned, the deck 40 can be easily aligned and installed along the deck connecting member 500.

The base portion 510 may be formed to extend long in the other side in the width direction based on the vertical connection portion 520 .

Accordingly, the first coupling portion 560 of the new deck connecting member 500 is connected to the second coupling portion 570 of the other end of the base portion 510 of the deck connecting member 500 previously disposed on the joist 30 Since it can be easily combined, ease of construction can be improved. Specifically, for example, even if the new deck connecting member 500 is pushed slightly to one side in the width direction, the first support part 540 of the new deck connecting member 500 is placed on the joist 30 and the joist 30. While being inserted between the arranged decks 40, the first coupling portion 570 of the new deck connecting member 500 is attached to the second coupling portion 570 of the deck connecting member 500 previously disposed on the joist 30. can be combined

For example, an upper portion near the other end of the base portion 510 may be provided with a locking protrusion 512 extending from the base portion 510 in a "b" shape. The second coupling part 570 may be defined by a space between the base part 510 and the “L” shape of the locking jaw 512 . Accordingly, the second coupling portion 570 coupled to the adjacent deck connection member 500 can be easily formed at low cost with a simple configuration.

A cutting groove 514 may be formed to extend in the longitudinal direction in the base portion 510 . Accordingly, during construction, the length of the deck connection member 500 in the width direction can be easily adjusted by easily cutting the base portion 510 in the longitudinal direction according to the width of the deck 40 and the like. Therefore, even if the deck 40 has a small width, the two deck connecting members 500 respectively installed on both sides in the width direction of the deck 40 can be easily aligned and installed while being coupled to each other. Thus, the deck 40 can also be easily aligned and installed along the deck connection member 500 and the distance between adjacent decks 40 can be maintained constant. In this regard, it will be described later.

In addition, since the deck 40 is supported by the deck connecting member 500 having a width matched to the width of the deck 40, the deck 40 is stably supported and the deformation of the deck 40 is effectively suppressed, The durability of the structure can be improved.

On the other hand, when the base portion 510 is cut in the longitudinal direction along the cutting groove 514, the locking jaw 512 near the other end of the base portion 510 is removed, so that the base portion 510 and the locking jaw 512 The second coupling part 570 defined by may be removed.

Therefore, on the other side of both sides in the width direction of the vertical connecting portion 520 or the first support portion 540, the first coupling portion 560 of the adjacent deck connecting member 500 replaces the second coupling portion 570. A coupled third coupling portion 575a may be formed. In this regard, it will be described later.

The base portion 510 may be fixed to the upper portion of the joist 30 through a fixing means 60 coupled to the base portion 510 and the joist 30 below the base portion 510. The fixing means 60 may correspond to, for example, bolts, nuts, nails, pieces, rivets, and the like. However, the fixing means 60 is not limited thereto.

On the other hand, the base part 510 is connected to the first area A between the vertical connection part 520 and the second support part 550 and the second support part 550, and is connected to the other side of the second support part 550 in the width direction. It may be configured to include an existing second region (B). The first area A and the second area B may be spaced apart from each other in the width direction and connected via the second support part 550 .

The fixing means 60 may be combined with the second region (B) and the joist 30 below the second region (B). Accordingly, the moisture introduced into the first area (A) of the base part 510 along the vertical connection part 520 is blocked by the second support part 500, and the fixing means 60 located in the second area (B) ) cannot penetrate. Therefore, the durability of the deck structure can be improved by preventing the fixing means 60 from being damaged by corrosion due to moisture and the like easily at low cost with a simple configuration.

The vertical connecting portion 520 extends upward from the base portion 510 and may be interposed between the side surfaces of the decks 40 disposed opposite to each other. In addition, the vertical connection portion 520 may be formed extending long along the longitudinal direction of the deck 40 .

As shown in the drawing, the vertical connection part 520 may extend upward from one end among both ends of the base part 510 in the width direction.

Accordingly, since the base part 510 does not exist on one side in the width direction based on the vertical connection part 520, the length of the base part 510 in the width direction is shortened so that the base part 510 is connected to the upper surface of the joist 30. The contact area is reduced. Therefore, when the deck connecting member 500 is pushed into the deck 40 previously disposed above the joist 30 in a state in which the deck connecting member 500 is disposed above the joist 30, the deck connection reduces the frictional force. Since the member 500 can be easily installed, ease of installation is improved.

In addition, since the deck connecting member 500 can be easily tilted to one side from both sides in the width direction in a state where the deck connecting member 500 is disposed above the joist 30, the deck connecting member 500 is placed on the joist line. Since it can be easily installed on the deck 40 previously disposed above the 30, the ease of installation is improved. In this regard, it will be described later.

Meanwhile, a third coupling part 575a may be formed on the other side of both sides of the vertical connector 520 in the width direction. Specifically, for example, a protrusion 523 protruding to the other side in the width direction at a predetermined distance from the base portion 510 may be formed on the other side surface of the vertical connection part 520 in the width direction, and the third coupling part Area 575a may correspond to a groove defined by a space between the base part 510, the vertical connection part 520, and the protrusion 523. Here, the protrusion 523 may be formed to extend long in the longitudinal direction.

Accordingly, the third coupling portion 575 coupled to the first coupling portion 560 of the adjacent deck connecting member 500 can be easily formed at low cost with a simple configuration.

The deformation preventing portion 530 may protrude from the vertical connection portion 520 to both sides in the width direction and may be respectively coupled to upper surfaces of adjacent decks 40 disposed opposite to each other. For example, the deformation preventing portion 530 may protrude from the upper end of the vertical connection portion 520 to both sides in the width direction, as shown in the drawing.

The deformation preventing portion 530 may extend along the longitudinal direction of the deck 40 and may be formed at a higher position than the first support portion 540 .

The deformation preventing unit 530 may press the upper surfaces of the adjacent decks 40 that are opposed to each other.

Accordingly, since deformation of the deck 40 is prevented, durability of the deck structure may be improved. In addition, since the deformation preventing unit 530 is coupled to the upper surface of the deck 40, as in the prior art for preventing deformation of the deck 40, grooves are created on both sides of the deck 40 and the deck connection member is connected to the deck. There is no need to engage the grooves formed on both sides of (40). Thus, the manufacturing/processing cost of the deck 40 can be reduced.

A water channel groove 532 may be formed to extend along the longitudinal direction of the deck 40 on the upper surface of the deformation preventing part 530 .

Accordingly, the moisture on the upper surface of the deformation preventing portion 530 does not flow to the bottom of the deformation preventing portion 530 along both ends in the width direction of the deformation preventing portion 530, and along the waterway groove 532, the deformation preventing portion ( 530) may be discharged to both ends in the longitudinal direction. Therefore, since moisture does not penetrate into the base portion 510, the durability of the deck structure can be improved by preventing the fixing means 60 from being damaged by corrosion due to moisture easily and at low cost with a simple configuration.

The first support part 540 may include one side support part 540a provided on one side in the width direction with respect to the vertical connection part 520 and the other support part 540b provided on the other side in the width direction.

One support part 540a or the other support part 540b may be formed on the base part 510 or the vertical connection part 520 . That is, the one side support portion 540a or the other side support portion 540b may protrude upward from the base portion 510 near the vertical connection portion 520 or protrude from the vertical connection portion 520 in the width direction.

For example, as shown in the drawing, one side support portion 540a or the other side support portion 540b may be formed to protrude from the vertical connecting portion 520 to one side or the other side in the width direction.

As another example, unlike the drawing, the one side support part 540a or the other support part 540b may be formed to protrude upward from the base part 510 on one side or the other side in the width direction with respect to the vertical connection part 520. At this time, one side support portion 540a or the other side support portion 540b protruding from the base portion 510 may be formed near the vertical connection portion 520 .

In addition, the first support portion 540 may extend along the longitudinal direction of the deck 40 and may be formed at a lower position than the deformation preventing portion 530 .

The first support part 540 may respectively support bottom surfaces of adjacent decks 40 disposed facing each other. Specifically, one side support portion 540a may support the bottom surface of the deck 40 disposed on one side in the width direction with respect to the vertical connection portion 520 among the opposing decks 40, and the other side support portion 540b may support the bottom surface of the deck 40 disposed on the other side in the width direction relative to the vertical connection portion 520 among the decks 40 disposed opposite to each other.

In this way, by forming the first support portion 540, the adjacent deck 40 is stably supported, so that the durability of the deck structure can be improved.

In addition, since the one side support part 540a is not formed on the base part 510 but protrudes from the vertical connection part 520 to one side in the width direction, the vertical connection part 520 is formed at one end of the base part 510 in the width direction. Since it can extend upward from, as described above, it is possible to easily install the deck connecting member 500, thereby improving ease of installation.

A vertical extension part 542 extending downward may be provided at one end of the one side support part 540a in the width direction. Accordingly, the lower end of the vertical extension 542 is in contact with the joist 30 so that the vertical extension 542 can be supported by the joist 30 and one end of the one side support 540a is the vertical extension 542 ) Since it can be supported by, one side support (540a) can more stably support the deck (40).

A first coupling part 560 to be described below may be formed on one side of both sides of the vertical extension part 542 in the width direction. Accordingly, the first coupling portion 560 coupled to the second coupling portion 570 or the third coupling portion 575 of the adjacent deck connecting member 500 can be easily formed at low cost with a simple configuration.

On the other hand, unlike the drawing, when the other side support portion 540b is formed by protruding upward from the base portion 510 on the other side in the width direction with respect to the vertical connection portion 520, the third coupling portion 575a is the vertical connection portion ( 520) may be formed on the other side surface of the other support portion 540b instead of being formed on the other side surface in the width direction.

Specifically, for example, a protrusion protruding to the other side in the width direction at a predetermined distance from the base portion 510 may be formed on the other side surface of the other side support portion 540b in the width direction, and a third coupling portion 575a ) may correspond to a groove defined by a space between the base part 510, the other support part 540b and the protrusion.

The second support part 550 may include a part spaced apart from the first support part 540 and protruding upward from the base part 510 on the other side of the first support part 540 in the width direction. In addition, the second support part 550 may extend along the longitudinal direction of the deck 40 .

The second support part 550 may support the deck 40 disposed on the other side with respect to the vertical connection part 520 among the opposing decks 40 .

In this way, since the second support portion 550 is formed, the deck 40 is stably supported and deformation of the deck 40 is prevented, so that the durability of the deck structure can be improved. In addition, when the deck 40 and the deck connecting member 500 are installed, the second support 550 of the deck connecting member 500 previously installed on the top of the joist 30 is installed on the deck connecting member 500. The downward inclination of the other side end in the width direction of (40) can be suppressed. Therefore, the deck 40 can be easily installed on the pre-installed deck connecting member 500, and a new deck connecting member ( 500) can be easily installed, so the ease of installation is improved.

Conversely, when the second support portion 550 is not formed, the other side end in the width direction of the deck 40 is greatly inclined downward, and a new deck connection member 500 is placed on the other side end in the width direction of the deck 40. ) may not be easily installed.

At this time, the second support part 550 is formed below the middle part in the width direction of the deck 40 disposed on the other side with respect to the vertical connection part 520 among the opposing decks 40, so that the width of the deck 40 You can support the middle part of the direction.

Accordingly, the deck 40 can be more stably supported and the deformation of the deck 40 can be effectively prevented, thereby improving the durability of the deck structure. In addition, since the deck 40 and the deck connecting member 500 are installed, the other end in the width direction of the deck 40 is effectively suppressed from inclining downward, so that the deck 40 and the deck connecting member 500 can be easily installed. Therefore, ease of installation is improved.

The second support part 550 extends upward from the base part 510 and extends along the longitudinal direction of the deck 40 in the first vertical part 552 and the width direction from the upper end of the first vertical part 552. It may be configured to include a horizontal portion 554 that protrudes into and extends along the longitudinal direction of the deck 40.

Accordingly, the second support portion 550 can be easily formed with a simple configuration at low cost.

In addition, the second support portion 550 is formed on the other side of the first vertical portion 552 in the width direction, protrudes downward from the horizontal portion 554, and extends long along the longitudinal direction of the deck 40. (558) may be further included.

The first vertical portion 552 may be coupled to the first area (A) of the base portion 510 and the second vertical portion 558 may be connected to the second area (B) of the base portion 510 .

Specifically, for example, the first vertical portion 552 protrudes upward from the first area A at a predetermined distance from the other widthwise end of the first area A of the base portion 510 to form a horizontal portion. 554, and the second vertical portion 558 protrudes upward from one end of the second region B of the base portion 510 in the width direction and is coupled to the horizontal portion 554.

At this time, when the first area (A) and the second area (B) of the base portion 510 are spaced apart from each other in the width direction, the first area (A) and the second area (B) are the second support portion ( 550) can be connected as a medium.

In the horizontal portion 554, a cutting groove 556 may be formed extending in a longitudinal direction. Specifically, the cut groove 556 may be formed to elongate in the longitudinal direction on the horizontal portion 554 between the first vertical portion 552 and the second vertical portion 558 .

Accordingly, it is possible to easily adjust the width direction length of the deck connecting member 500 by easily cutting the horizontal portion 554 in the longitudinal direction according to the width of the deck 40 during construction. Therefore, even if the deck 40 has a small width, the two deck connecting members 500 respectively installed on both sides in the width direction of the deck 40 can be easily aligned and installed while being coupled to each other. Therefore, the deck 40 can also be easily aligned and installed along the deck connection member 500, and the distance between adjacent decks 40 can be maintained constant. In this regard, it will be described later.

In addition, since the deck 40 is supported by the deck connecting member 500 having a width matched to the width of the deck 40, the deck 40 is stably supported and the deformation of the deck 40 is effectively suppressed, The durability of the structure can be improved.

In addition, even if the horizontal portion 554 is cut at the cutting groove 556 and a part of the second support portion 550 on the other side in the width direction with respect to the cutting groove 556 is removed, the cutting groove 556 is the standard. The remaining portion of one side in the width direction may support the bottom surface of the deck 40. Therefore, as described above, the durability and ease of construction of the deck structure can be improved by the second support part 550 .

On the other hand, when the horizontal portion 554 of the second support portion 550 is cut in the longitudinal direction along the cutting groove 556, the second vertical portion 558 can be removed and the base connected to the second vertical portion 558 The locking jaw 512 near the other end of the second region B of the portion 510 may also be removed. Accordingly, the second coupling portion 570 defined by the base portion 510 and the locking jaw 512 may also be removed.

Therefore, the third coupling coupled to the first coupling portion 560 of the adjacent deck connecting member 500 in place of the second coupling portion 570 on the other side of both side surfaces in the width direction of the first vertical portion 552. A portion 575b may be formed. Accordingly, the third coupling portion 575b coupled to the first coupling portion 560 of the adjacent deck connecting member 500 can be easily formed at low cost with a simple configuration.

Specifically, for example, a protrusion 553 protruding to the other side in the width direction at a predetermined distance from the base portion 510 may be formed on the other side surface of the first vertical portion 552 in the width direction. The coupling portion 575b may correspond to a groove defined by a space between the base portion 510 , the first vertical portion 552 , and the protrusion 553 . Here, the protrusion 553 may be formed to elongate in the longitudinal direction.

The first coupling portion 560 may be formed at one end of the deck connection member 500 in the width direction. Specifically, for example, the first coupling part 560 may be formed on one side of both sides in the width direction of the vertical extension part 542 .

However, it is not limited to this configuration, and unlike the drawings, when the vertical extension part 542 is not formed, the first coupling part 560 corresponds to one end of the deck connection member 500 in the width direction. It may be formed on one side of both sides in the width direction of the vertical connector 520.

In addition, the first coupling portion 560 may correspond to a protrusion protruding to one side in the width direction and may be formed to extend long along the length direction. Accordingly, the first coupler 560 can be easily formed at low cost with a simple configuration.

On the other hand, when the first coupling portion 560 corresponds to a protrusion, the length of the first coupling portion 560 in the width direction is the width of the deck 40 and the second coupling portion 570 or the third coupling portion ( 575) may be determined according to the location. In this regard, it will be described later.

The second coupling part 570 may be formed at the other end of the width direction of the deck connection member 500 . Specifically, for example, the second coupling part 570 may be formed at the other end of the base part 510 in the width direction.

In addition, the second coupling portion 570 may correspond to a groove into which the first coupling portion 560 is inserted, and may extend along the longitudinal direction. Specifically, for example, the second coupling portion 570 may correspond to a groove defined by a space between the other end of the base portion 510 in the width direction and the "L" shape of the locking jaw 512 .

Accordingly, the second coupler 570 can be easily formed with a simple configuration at low cost.

The first coupling portion 560 and the second coupling portion 570 are coupled to each other, so that the deck connecting member 500 and the adjacent deck connecting member 500 may be coupled to each other. Accordingly, the deck connection member 500 can be easily aligned and installed while being coupled to each other with the adjacent deck connection member 500 . Therefore, the deck 40 can also be easily aligned and installed along the deck connection member 500, and the distance between adjacent decks 40 can be maintained constant.

In addition, since the adjacent deck connecting members 500 are coupled to each other through the first coupling portion 560 and the second coupling portion 570, the deck connecting member 500 cannot leave the installed position, so a small number of fixing means are required. Even if the deck connecting member 500b is fixed on the joist 30 in (60), the deck connecting member 500 can be stably fixed on the joist 30. Thus, ease of installation can be improved.

The third coupling part 575 may be formed on the other side of both side surfaces in the width direction of the vertical connection part 520 or the first vertical part 552 .

However, it is not limited to this configuration, and as described above, unlike the drawings, when the other side support portion 540b protrudes upward from the base portion 510 on the other side in the width direction based on the vertical connection portion 520. In this case, the third coupling part 575a may not be formed on the other side surface of the vertical connection part 520 in the width direction, but may be formed on the other side surface of the other support part 540b.

The third coupling portion 575 may correspond to a groove formed in the width direction, may be coupled to the first coupling portion 560 in place of the second coupling portion 570, and extend long in the longitudinal direction. It can be.

Specifically, for example, the third coupling part 575 is any one of the base part 510, the vertical connection part 520, the other side support part 540b or the first vertical part 552, the protrusion 523, 553) may correspond to a groove defined by the space between them.

Accordingly, the third coupling portion 575 can be easily formed at low cost with a simple configuration.

The first coupling part 560 and the third coupling part 575 are coupled to each other, so that the deck connecting member 500 and the adjacent deck connecting member 500 can be coupled to each other. Accordingly, even if the cutting grooves 514 and 556 formed in the base portion 510 or the horizontal portion 554 are cut and the second coupling portion 570 is removed, the deck connecting member through the third coupling portion 575 500 can be easily aligned and installed while being coupled to each other with the adjacent deck connecting member 500. Therefore, the deck 40 can also be easily aligned and installed along the deck connection member 500, and the distance between adjacent decks 40 can be maintained constant.

6 to 8 are views showing a state in which the length of the deck connection member in the width direction is adjusted for the deck having a width of various sizes.

Specifically, FIG. 6 is a deck connecting member (500p) of the horizontal portion 554 is cut in the cut groove (556, FIG. 4) portion to fit the small width of the deck 40, the deck connecting member (500p) The first coupling portion 560 of the adjacent deck connecting member 500q is coupled to the third coupling portion 575b formed on the other side of the first vertical portion 552 of the coupled state. At this time, the width direction length of the first coupling portion 560 of the adjacent deck connecting member (500q) may be formed short.

At this time, the length in the width direction of the first coupling portion 560 of the adjacent deck connecting member 500q may be formed to extend long.

8 shows that the horizontal portion 554 of the deck connecting member 500p is cut at the cutting groove 556 (FIG. 4) to match the width of the deck 40, and the first vertical portion of the deck connecting member 500p ( 552) shows a state in which the first coupling portion 560 of the adjacent deck connection member 500q is coupled to the third coupling portion 575b formed on the other side. At this time, the length in the width direction of the first coupling portion 560 of the adjacent deck connecting member 500q may be formed to extend long.

As such, the length of the first coupling portion 560 in the width direction may be determined according to the width of the deck 40 and the position of the third coupling portion 575 . Accordingly, even if the deck 40 has a width of various sizes, the two deck connection members 500p and 500q respectively installed on both sides in the width direction of the deck 40 can be easily aligned and installed while being coupled to each other. Therefore, the deck 40 can also be easily aligned and installed along the deck connection member 500, and the distance between adjacent decks 40 can be maintained constant.

In addition, since the deck 40 is supported by the deck connecting member 500 having a width matched to the width of the deck 40, the deck 40 is stably supported and the deformation of the deck 40 is effectively suppressed, The durability of the structure can be improved.

Accordingly, along the vertical connection part 520 and the first support part 540 of the deck connection member 500q, moisture introduced into the point where the first coupling part 560 and the second coupling part 570 are coupled is caught. It is blocked by the other end of 512 and cannot penetrate into the fixing means 60 located in the second area (B) of the base part 510 and can be discharged to both ends in the longitudinal direction. Therefore, the durability of the deck structure can be improved by preventing the fixing means 60 from being damaged by corrosion due to moisture and the like easily at low cost with a simple configuration.

One side surface of the vertical connector 520b in the width direction may correspond to a smooth vertical surface. Therefore, when the first deck connecting member 500a or the second deck connecting member 500b is installed at the side end of the deck structure in the width direction, the side end surface can be smoothed, so the deck structure Ease of construction can be improved because there is no need to install a separate finishing member at the side end in the width direction. In this regard, it will be described later.

In addition, the fourth coupling portion 580 extends along the longitudinal direction of the deck 40 at a point protruding from the bottom of the first vertical connection portion 520a to the other side in the width direction, and the fifth coupling portion 590 Is protruded from the bottom of the second vertical connection portion (520b) to one side in the width direction and is formed to extend along the longitudinal direction of the deck 40, so that the fourth coupling portion 580 and the fifth coupling portion 590 are coupled In the state, between the first vertical connection portion 520a and the second vertical connection portion 520b, a waterway groove c extending upward along the longitudinal direction of the deck 40 may be formed.

Accordingly, moisture on the upper surface of the vertical connection part 520 or the deformation preventing part 530 cannot flow to the lower part of the deformation preventing part 530 along both ends in the width direction of the deformation preventing part 530, and the water channel groove (c) It can be discharged to both ends in the longitudinal direction of the vertical connection part 520 along the. Therefore, since moisture does not penetrate into the base portion 510, the durability of the deck structure can be improved by preventing the fixing means 60 from being damaged by corrosion due to moisture easily and at low cost with a simple configuration.

On the other hand, as shown in Figures 3 and 4, the finishing member (R) may be installed at the other end of the width direction of the deck structure.

The finishing member (R) may support the bottom surface of the other side end in the width direction of the deck 40 and may be coupled to the other side end portion in the width direction of the upper surface of the deck 40. Like the deck connection member 500, the closing member R may be formed to extend in the longitudinal direction.

The finishing member R may smooth the other end of the deck structure in the width direction.

On the other hand, since the second deck connecting member 500b having a smooth widthwise side is installed at one end of the deck structure in the width direction, a finishing member for smoothing one end of the deck structure in the width direction may be unnecessary. Thus, ease of installation can be improved.

In the second width matching step (S750), as shown in FIGS. 6 to 8, according to the width of the deck 40 and the position of the second coupling portion 570 or the third coupling portion 575, the first coupling portion 560 ) in the width direction can be determined. For example, the length of the first coupling portion 560 in the width direction may be adjusted by cutting the protrusion of the first coupling portion 560 .

In the deck connection member installation step (S760), the deck connection member 500 may be installed on the joists 30.

When there is no deck 40 already disposed above the joists 30, the second deck connecting member 500b may be disposed on the joists 30 as shown in FIGS. 3 and 4. At this time, the second deck connecting member (500b) may be installed in a direction orthogonal to the joists (30).

11 and Likewise, the other side in the width direction of the deck 40a previously disposed above the joist 30 between one side in the width direction of the deformation preventing portion 530 of the deck connection member 500q and one side in the width direction of the first support portion 540 Insert, and combine the first coupling portion 560 of the deck connecting member (500q) with the second coupling portion 570 of the deck connecting member (500p) already fixed to the joist 30 to form a deck connecting member (500q) Can be placed on top of the joist 30.

After being inserted between (30) and the pre-arranged deck (40a), when the deck connecting member 500 is pushed to one side in the width direction, the deck connecting member 500 is attached to the pre-arranged deck (40a). It can be easily installed, so the ease of installation is improved.

On the other hand, even when there is a pre-arranged deck 40a above the joist 30 and the deck connecting member 500 is not installed on the other side in the width direction of the pre-arranged deck 40a, the deck connecting member ( 500), as shown in FIGS. 3 and 4, the finishing member R may be installed on the joist 30.

In the deck connecting member fixing step (S770), as shown in FIG. 12, the deck connecting member 500q may be newly fixed to the joist 30 using the fixing means 60.

At this time, since the position where the fixing means 60 is installed is exposed to the outside, the deck connection member 500 can be easily fixed to the top of the joist 30.

In addition, the finishing member R may be newly fixed to the joist 30 using the fixing means 60.

In the deck arrangement step (S780), as shown in FIG. 13, the other side in the width direction of the deformation preventing portion 530 of the newly fixed deck connection member 500q and the other side in the width direction of the first support portion 540 are not previously arranged.
