Recently, deck roads made of wood have been widely constructed in outdoor walking trails, hiking trails, waterside parks, and country housing complexes. This can be said to be because wooden deck rods are more nature-friendly than other materials, absorb shock and vibration, provide an excellent walking environment, and provide beautiful harmony with the surrounding environment.

These deck rods include a steel joist, a plurality of wooden deck members that are seated so as to cross the upper part of the joist and fixed to the upper part of the joist, and handrails installed along both sides of the wooden deck member.

The deck material is usually fixed to the joist using nails or screws. During the fixing process, the wooden deck material splits, and after fixing the deck material with nails or screws, the deck material may deform over time and the nail or screw may fall out. Not only do nails and screws rust and corrode, but there is a problem in that the nails or screws protrude from the deck material, compromising walking safety.

In order to solve the above problem, many technologies for fixing deck materials using clips have been recently disclosed.

A deck rod system using a deck connection eccentric clip according to an example of the present invention and including a handrail that is easy to maintain includes joists (10); Deck members 20 installed on the upper side of the joists 10 in a direction intersecting the joists 10; Eccentric clips (30) for fixing the deck materials (20) to the joist (10); Fastening members 40 that secure the eccentric clips 30 to the joist 10; It may include a railing including railing pillars 50 installed on one or both sides of the deck material 20.

The joists 10 may be steel in the shape of a square tube with an empty interior. A pair of joists 10 is installed in a balanced manner, but if necessary, one or more joists 10 may be installed in the middle of a pair of balanced joists 10. In addition, the joists 10 do not necessarily have to be installed horizontally, and may be installed in a trapezoidal shape depending on the shape of the deck rod, or may be installed only on one side of the deck rod. On the upper surface of the joist 10, through holes for inserting fastening bolts 42, which will be described later, may be formed at regular intervals, or long cut holes may be formed continuously or intermittently in the longitudinal direction.

The deck materials 20 may be installed in a direction that intersects the lower joists 10. That is, the deck material 20 may be installed in a direction perpendicular to or obliquely intersecting the joist 10. The deck material 20 may be made of natural wood, synthetic wood, or pine carbonized wood. Irregularities may be formed on the upper surface of the deck material 20 to prevent slipping. An elastic groove may be formed on the side of the deck material 20 for engaging the eccentric clip 30, which will be described later.

The railings can be installed on both sides or one side of the deck materials 20, that is, the deck road, to prevent falls of pedestrians, etc., thereby promoting safety. The handrail connects the handrail pillars 50 and the handrail pillars 50 installed at regular intervals along the side of the deck road and may include a plurality of horizontal bars 60 installed spaced apart from each other up and down. In addition, horizontal bars 60 can be installed only on the upper and lower sides between the handrail pillar 50 and the handrail pillar 50, and vertical bars 61 can be installed in the vertical direction between the upper and lower horizontal bars 60.

The railing pillar 50 includes an inner pillar 52 having a square cross-section and four external members 542 separated from each other surrounding the outside of the inner pillar 52, and an outer pillar having a square outline. It may include (54) and connecting chains 544 that connect the four external members 542 to each other.

The internal pillar 52 can be either an empty rectangle or a full rectangle. The inner pillar 52 is made of metal, but other materials such as synthetic resin are also possible if strength is ensured. The internal pillar 52 can be firmly fixed to the lower side so that the handrail pillar 50 has rigidity.

Each of the four external members 542 has a first surface 5422 in contact with each side of the square-shaped internal pillar 52, and a first surface 5422 at both ends of the first surface 5422. A second surface 5424 extending diagonally, and an external pillar 54 that is bent in the same direction, that is, all to the right or all to the left, at each end of the second surface 5424, so that the outline has a square shape. It may include a third surface 5426 extending in a direction perpendicular to each outer side. Accordingly, the facing external members 542 may be point symmetrical to each other at the center of the handrail pillar 50. That is, as shown in the drawing, each of the external members 542 may be formed in a trapezoidal shape with one outer side cut into a triangular shape and attached to the other side. In this shape, the four external members 542 are formed into a shape in which the four external members 542 are inserted into each other, so that the coupling force can be increased. In addition, connection slits into which the connecting chain 544 can be inserted are formed on both sides of the second surface 5424 facing each other in the external member 542, and both ends of the connecting slit have spherical slit holes with increased width. can be formed. This slit hole prevents the connecting slit from being easily split, and at the same time prevents the connecting chain 544 from easily falling out. The connection slits may also be formed on both sides of the third surface 5426 of the external member 542. Additionally, connection slits may be formed on both the second side 5424 and the third side 5426. The external member 542 may be made of natural wood, synthetic wood, wax pine carbonized wood, or plastic. Additionally, the external member 542 can be painted or coated.

The connecting chain 544 is inserted into the connecting slit in the shape of a plate and can couple adjacent external members 542 to each other. The connecting chain 544 has both ends formed as spherical connecting holes and is inserted into the slit hole, thereby preventing separation of the two external members 542 and firmly coupling them.

A handrail cap 56 covering the upper side of the handrail cap 50, an elastic fastener 562 extending to the lower side of the handrail cap 56, and a locking hole formed through the upper side of the inner pillar 52 ( 522) may further be included. When the handrail cap 56 is lowered, the elastic fastener 562 formed at the lower center of the handrail cap 56 may be elastically coupled to the catching hole 522 of the inner pillar 52.

The elastic fasteners 562 may be formed as a pair in the center of the handrail cap 56, and may have one fastening ring on the lower side or two fastening rings on the top and bottom. On the upper side of the inner pillar 52, one or two catching holes 522 may be formed penetrating on both opposing sides. Therefore, when the handrail cap 56 is lowered, the elastic fastener 562 moves down along the inner pillar 52, and the fastening ring on the lower side is elastically caught in the catching hole 522, thereby fixing the elastic cap. . Therefore, the handrail cap 56 can be fixed simply by lowering it downward, and at the same time, it cannot be easily separated from the outside, thereby preventing theft.

The lower side of the handrail pillar 50 may further include a finishing cap 58 covering the lower side, and a fastener 582 for fixing the finishing cap 58 to the external pillar 54 or the deck material 20. there is. The finishing cap 58 is formed in a pair of U-shapes separated from each other and can be joined to the handrail pillar 50 by inserting it from both sides. Therefore, installation of the closing cap 58 can be done quickly and easily. In other words, the finishing cap 58 can be installed at any time, such as after installing the external pillar 54 of the handrail pillar 50 or after installing the horizontal bar 60, so construction can be very convenient. In addition, if the finishing cap 58 is damaged during use, it can be easily replaced with a new closing cap 58, making maintenance very convenient. In the case of the prior art, in order to install a new finishing cap, there was a difficulty in having to remove all the handrail caps, horizontal bars, etc., then install a new finishing cap and reconnect the horizontal bars, etc., but this embodiment can solve this problem. .

The eccentric clip 30 fixes the deck material 20 to the joist 10, is seated on the upper surface of the joist 10, and has a fastening hole 34 for fastening the fastening member 40 through the top and bottom. It may include a formed body portion 32 and wings 33 having an arc shape extending upward from both sides of the body portion 32 and having elastic force.

The body portion 32 may have an appropriate thickness in the vertical direction and may have a square shape in plan view. The fastening hole 34 may be formed one in the center of the body 32 or two on both sides.

The wing portion 33 extends outward and upward from both sides of the body portion 32, and then extends again inward and upward to provide an elastic deformation space between the wings 33 on both sides, and a deck installed on both sides. It can be closely inserted into the elastic groove of material 20. That is, the wings 33 on both sides are elastically inserted into the elastic grooves of the deck material 20 installed on both sides, thereby tightly supporting the deck material 20 and preventing the deck material 20 from falling out. The wing portion 33 can respond well to expansion and contraction due to temperature changes and moisture absorption of the wooden deck material 20 due to its elastic force. The deck material 20 has elastic grooves formed to correspond to the shape of the arc-shaped wings 33 of the eccentric clip 30, so that it adheres well to the wings 33 as a whole and can be closely adhered even during the expansion and contraction process. . The wing portion 33 may become gradually thinner toward the top. Due to the thick lower side, it is firmly fixed to the body portion 32, and at the same time, due to the thin upper side, it responds well to the expansion and contraction of the deck material 20, and can also be pulled out to the upper side or inserted into the lower side of the deck material 20 when necessary. It can be made possible.

The material of the eccentric clip 30 is metal, but other materials can be used if strength and elasticity are secured.

The body portion 32 includes a compressed space portion 35 formed by cutting and removing the lower surface of one side, and when the eccentric clip 30 is fixed to the joist 10 with the fastening member 40, the eccentric clip 30 ) is tilted downward on one side due to the compressed space portion 35, so that the previously installed deck material 20 can be fixed in close contact with it. The compressed space portion 35 may be formed to extend further from one end of the body portion 32 than the middle. That is, the compressed space portion 35 may be formed to extend further to the other side than the center of the fastening hole 34 of the body portion 32. This may cause the body portion 32 to tilt downward on one side when the fastening member 40 is fastened.

An appropriate cutting angle of the compressed space portion 35 may be approximately 2 to 3 degrees. If the cutting angle is too small, the adhesion effect is reduced, and if it is too large, it may cause excessive adhesion. However, considering the width and material of the deck material 20, the environment of the deck rod installation area, etc., the cutting angle can be made larger or smaller.

An induction passage 36 formed by a long recess in the longitudinal direction on the lower surface of the body 32 at the position of the compressed space 35, and an injection passage 37 recessed in a right angle direction at a point of the induction passage 36. It may further include an injection hole 39 formed through the upper surface of the body 32 to the injection passage 37.

It may further include fillers such as silicone and adhesive that are injected into the injection passage 37 and the induction passage 36 through the injection hole 39. The filler injected into the induction passage 36 through the injection passage 37 attaches the body 32 and the joist 10 and reduces noise that may occur between the eccentric clip 30 and the joist 10. You can.

The injection passage 37 may extend to the other side of the body portion 32, that is, the lower surface opposite to the compressed space portion 35. In this case, the filler may be partially filled in the other lower surface of the body portion 32. When fastening with the fastening member 40, the eccentric clip 30 moves downward due to the compressed space 35, and therefore the lower part of the other side opposite to the compressed space 35 can be filled with filler. When the filler is filled up to the lower surface of the other side of the body portion 32, the body portion 32 and the joist 10 are perfectly coupled without movement, and thus noise, etc. can be completely prevented. However, whether or not the other lower surface of the body portion 32 is filled may be affected by the cutting angle and the width of the body portion 32. That is, if the width of the body portion 32 is narrow and the cutting angle is small, the space on the other lower surface of the body portion 32 may be small and may not be filled.

The fastening member 40 includes a fastening bolt 42 inserted through the fastening hole 34 of the body 32, and an extension fastened to the fastening bolt 42 and fixed to the inside of the joist 10. It may include a nut (44). The expansion nut 44 includes an upper ring 442, a lower ring 444 spaced apart from the upper ring 442, and expansion portions 446 connecting the upper ring 442 and the lower ring 444. And, it may include a bent portion 448 provided in the middle of the expanded portions 446. The expansion portion 446 connects the upper ring 442 and the lower ring 444 and may be formed in plural numbers along the circumferential direction.

When the fastening bolt 42 is fastened to the expansion nut 44, the lower ring 444 is in close contact with the upper ring 442, and the expansion portion 446 is bent at the bent portion 448 and expands outward. By being fixed to the inside of the joist 10, the eccentric clip 30 can be firmly fixed to the joist 10. For this purpose, a screw may be formed inside the lower ring 444.

The upper ring 442 may include a neck portion 449 corresponding to the combined thickness of the body portion 32 of the eccentric clip 30 and the thickness of the upper surface of the joist 10. The height of the neck portion 449 can be manufactured in advance by considering the thickness of the body portion 32 of the eccentric clip 30 and the thickness of the upper surface of the joist 10.

The eccentric clip 30 can be fixed by inserting both the eccentric clip 30 and the expansion nut 44 into the fastening bolt 42 and inserting them along the cut hole of the joist 10. In addition, after inserting only the expansion nut 44 into the fastening bolt 42, it can be fastened by inserting the fastening hole 34 of the eccentric clip 30 installed at the fixed position from the upper side to the lower side. The method of fastening by inserting the expansion nut 44 into the fastening bolt 42 and then inserting the fastening hole 34 of the eccentric clip 30 from the top to the bottom can quickly and easily fix the eccentric clip 30. let it be In the case of the prior art, the method of fastening by inserting the bolt from the upper side of the clip and inserting the nut inside the joist had the problem of making the fastening work very difficult, but this problem can be completely solved in this implementation.

The bent portion 448 is formed to protrude slightly outward in advance to facilitate bending and expansion of the expanded portion 446 to the outside, or the inner portion of the middle portion of the expanded portion 446 is partially cut and removed to facilitate expansion to the outside. It can be made into a shape that can be bent and expanded.

The bent portion 448 is located above the center of the expanded portion 446, so that the expanded portion 446 on the upper side of the bent portion 448 is shorter than the expanded portion 446 on the lower side of the bent portion 448. The extension 446 may be tightly secured to the interior of the joist 10. That is, the longer lower extension part 446 presses the shorter upper extension part 446 obliquely upward, thereby enhancing the effect of the extension part 446 being closely adhered to the inside of the joist 10. there is.

It may further include yokes 70 installed on the lower side of the joists 10 in a direction parallel to or intersecting the joists 10. The yoke 70 may be formed of a hollow steel square tube, H beam, etc. The yoke 70 can be installed in a direction parallel to the deck rod and in a direction perpendicular thereto to support the joists 10. In addition, the lower side of the yoke 70 may further include a vertically installed pile, a foundation installed on the lower side of the pile, etc.
