Description

Deck assembly structure {DECK ASSEMBLY STRUCTURE}

The present invention relates to a deck assembly structure.

In recent years, deck assemblies made of wood have been used for flooring and walls of various buildings, outdoor walkways, mountain trails, waterfront parks, and powerhouses. This is because the wood deck assembly is more environmentally friendly than other materials, effectively absorbing shocks and vibrations to create a quiet environment, providing a visually comfortable feel and durability.

The deck assembly according to the prior art includes at least one support member installed at a place of installation, and a plurality of deck plates which are seated orthogonally to the top of the support member and fixed to the top of the support member. At this time, the support member is formed of a material having sufficient strength to support the deck plate, and the deck plate can be formed of wood that can be walked on by a pedestrian.

On the other hand, the deck plate can be fixed to the supporting member by using a fastening means, but nails and screws are most widely used as fastening means. However, there are many problems when using nails or screws as the fastening means. First, when a nail or a screw is put on the deck plate, damage to the deck plate formed of wood occurs, and a large amount of deck plate is lost in the process of fixing the deck plate. In addition, when the deck plate is fastened for a long time after fixing with a nail or screw, the deck plate deforms, causing the nails and screws to come off, break, or rust. Therefore, there is a problem that a nail or a screw protrudes from the deck plate and the pedestrian is caught by a projected nail or a screw.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, detailed description of related arts which may unnecessarily obscure the gist of the present invention will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a deck assembling structure according to an embodiment of the present invention, FIG. 2 is a sectional view of the deck assembling structure shown in FIG. 1, FIG.

1 to 4, a deck assembly structure according to an embodiment of the present invention includes a deck 100 having a plurality of concave grooves 130 formed in side surfaces thereof and having a plurality of parallel concave grooves 130, A first protrusion 210 protruding from one side surface and a second protrusion 220 protruded from the other side of the first protrusion 210. At least one of the first protrusion 210 and the second protrusion 220 is formed in the concave groove 130 And a fastening means 300 inserted into the through hole 230 to fasten the clip 200 to the support member 400. The fastening means 300 includes a fastening means 300 for fastening the clip 200 to the support member 400, .

The deck 100 is formed in a plate-like shape, which is finally walked by a pedestrian. Here, a plurality of decks 100 are provided, and the decks 100 are disposed in the supporting member 400 in parallel in the longitudinal direction. At this time, depressed concave grooves 130 are formed on both sides of the deck 100, and a first protrusion 210 or a second protrusion 220 of the clip 200 described later is inserted into the concave groove 130 . Specifically, the concave groove 130 has a main concave groove 131, which is recessed in the thickness direction center portion of the side surface of the deck 100, and a concave concave groove 131, which is recessed in the lower side of the side surface of the deck 100 And may include a groove 133. That is, two concave grooves 130 may be formed on one side surface. At this time, the main concave groove 131 is further recessed from the side surface of the deck 100 as compared with the auxiliary concave groove 133. That is, the main concave groove 131 is recessed deeper than the auxiliary concave groove 133. The first main protruding portion 211 of the first protruding portion 210 and the second main protruding portion 221 of the second protruding portion 220 are inserted into the main concave groove 131, The first auxiliary protrusion 213 of the first protrusion 210 and the second auxiliary protrusion 223 of the second protrusion 220 can be inserted. 5), the main concave groove 131 may be formed such that two straight lines meet so that the ends thereof form a predetermined angle. That is, the main concave groove 131 may have a sharp end. However, the main concave groove 131 need not necessarily have a sharp end, but may extend in a curved line when viewed from the cross section (see FIG. 6). That is, the main concave groove 131 may have rounded ends.

The material of the deck 100 (see Figs. 1 to 2) is not particularly limited, but may be formed of natural wood or carbonized wood. Here, the carbonized wood can be produced by heating the wood while restricting the air supply, volatilizing a part of the wood material, and leaving it with charcoal mainly composed of carbon. As described above, when the deck 100 is made of carbonized wood, it has a deformation reduction effect of 90% or more as compared with ordinary wood, and is less susceptible to moisture absorption and is resistant to moisture. There is an advantage to deck loading.

In addition, the deck 100 is formed with the recessed portion 160 on the exposed surface (the surface opposite to the surface contacting with the support member 400), thereby preventing the pedestrian from slipping when walking.

Meanwhile, the support member 400 plays a role of supporting the deck 100 in the lower part of the deck 100. Here, a plurality of support members 400 may be provided, and may be arranged in parallel in the longitudinal direction. In addition, the longitudinal direction of the support member 400 may be perpendicular to the longitudinal direction of the deck 100. Accordingly, one support member 400 can support the ends of the plurality of decks 100 along the length direction. Here, the support member 400 is not particularly limited, but may be a square pipe formed of metal to ensure excellent durability, and may be, for example, a KS zinc square pipe. At this time, each pipe means a pipe having a space formed therein and a polygonal cross-section.

The clip 200 serves to fix the deck 100 to the support member 400. Here, the clip 200 includes a first protrusion 210 protruding from one side and a second protrusion 220 protruding from the other side. The first protrusion 210 and the second protrusion 220 may be formed symmetrically with respect to the central axis passing through the center of the clip 200. [ At this time, at least one of the first protrusion 210 and the second protrusion 220 is inserted into the concave groove 130 of the deck 100. Specifically, the first protrusion 210 has a first main protrusion 211 protruding from the central portion in the thickness direction of the clip 200 and a recessed groove 130 protruding from the center of the clip 200, corresponding to the main recess 131 of the recess 130. [ (A lower portion adjacent to the support member 400) of the clip 200 so as to correspond to the auxiliary concave groove 133 of the clip 200. As shown in Fig. Similarly, the second protrusion 220 includes a second main protrusion 221 protruding from the central portion of the clip 200 in the thickness direction thereof to correspond to the main recessed groove 131 of the recessed groove 130, A second auxiliary protrusion 223 protruding from the lower end of the clip 200 (the lower portion adjacent to the support member 400) so as to correspond to the auxiliary recessed groove 133 of the clip 200. [ That is, the first protrusion 210 and the second protrusion 220 may be formed on two sides of the first protrusion 210 and the second protrusion 220, respectively. The first main protrusion 211 protrudes further from one side of the clip 200 than the first sub protrusion 213 and the second main protrusion 221 protrudes from a side of the clip 200 200 from the other side. That is, the first main protrusion 211 and the second main protrusion 221 protrude more than the first auxiliary protrusion 213 and the second auxiliary protrusion 223, respectively. The first main protrusion 211 and the second main protrusion 221 are inserted into the main concave groove 131 and the first auxiliary protrusion 213 and the second auxiliary protrusion 223 are inserted into the auxiliary concave groove 133, As shown in FIG. As a result, since the two projections 211, 213 or 221, 223 of the clip 200 are inserted into the two concave grooves 131, 133 of the deck 100, the deck 100 and the clip 200 are firmly fixed Can be combined.

5), when the main concave groove 131 is formed so as to meet two straight lines so that the ends thereof are at a predetermined angle, the first main protrusion 211 and the second main protrusion 221 (see FIG. 5) May be formed such that two straight lines meet so that the ends thereof form an angle. Alternatively, when the main concave groove 131 extends in a curved line, the first main protrusion 211 and the second main protrusion 221 may extend in a curve with respect to the transverse section (refer to FIG. 6). That is, when the distal end of the main concave groove 131 is sharp, the ends of the first main protrusion 211 and the second main protrusion 221 may be sharpened to correspond to the tip of the main concave groove 131, The distal ends of the first main protrusion 211 and the second main protrusion 221 may also be sharpened to correspond to the rounded end.

In addition, the clip 200 is formed with a through hole 230 penetrating in one direction (up and down direction). The fixing means 300 is inserted into the through hole 230 so that the clip 200 can be coupled to the supporting member 400. Here, the through hole 230 may not be formed on the center axis passing through the center of the clip 200, but may be formed closer to the second protrusion 220 than the first protrusion 210 as viewed from the transverse section . This is because the deck 100 is disposed on the supporting member 400 and the first protrusion 210 of the clip 200 is inserted into the concave groove 130 of the deck 100, (300). The through holes 230 are formed in the concave grooves 130 of the deck 100 and the main concave grooves 130 of the deck 100 in the state where the first protrusions 210 of the clip 200 are inserted into the concave grooves 130 of the deck 100. [ The through holes 230 are formed in the concave grooves 130 and the main concave grooves 131 of the deck 100 so that the concave grooves 130 and the main concave grooves 131 ), But can be exposed to the outside as much as possible. Therefore, the fixing means 300 can be easily inserted into the through hole 230. The through hole 230 may extend at a predetermined angle? With respect to the imaginary line V perpendicular to one surface of the support member 400 contacting the clip 200. That is, the through hole 230 does not extend perpendicularly to one surface of the support member 400 contacting the clip 200, but can extend at a predetermined angle?. Specifically, the through-hole 230 extends away from the first protrusion 210 as it goes away from one surface of the flat support member 400 in contact with the clip 200 (toward the upper side). When the through hole 230 is formed in the through hole 230, when the fixing means 300 is inserted into the through hole 230 and fixed to the support member 400, the force is generated by the fixing means 300 in the direction of the support member 400 The force can be applied not only to the deck 100 but also to the deck 100. The clip 200 is coupled to the support member 400 by the securing means 300 and can press the sides of the deck 100 to secure the deck 100 securely. At this time, the predetermined angle [theta] with which the through hole 230 is inclined with respect to the imaginary line V perpendicular to the one surface of the support member 400 is not particularly limited, but may be 0.5 [deg.] To 1.5 [deg.]. If the predetermined angle? Is less than 0.5 deg., The force for pressing the side surface of the deck 100 to the clip 200 is too small to firmly fix the deck 100 substantially, Is more than 1.5 degrees, the fastening force between the fixing means 300 and the support member 400 becomes too weak. Particularly, when the square pipe is used as the support member 400, since there is an empty space inside the support member 400, when the fastening means 300 (screw) is inserted at an angle exceeding 1.5 degrees, 400, each pipe) and the fixing means 300 (screw) is too weak to attach the clip 200 to the supporting member 400.

As shown in FIG. 1, at least two through holes 230 may be formed along the longitudinal direction of the clip 200, and the fixing means 300 may be attached to the at least two through holes 230 Can be inserted. As described above, when two or more through holes 230 are formed and the fixing means 300 is inserted into each of the through holes 230, the clip 200 is prevented from being rotated about the fixing means 300 So that the clip 200 can more reliably fix the deck 100 to the support member 400.

The fixing means 300 serves to couple the clip 200 to the support member 400. The fixing means 300 is inserted into the through hole 230 of the clip 200 so that one side of the fixing means 300 is engaged with the upper end of the through hole 230 and the other side of the fixing means 300 is coupled with the support member 400 through the pipe. At this time, the fixing means 300 may be a screw called a normal piece. When the fastening means 300 is inserted into the through hole 230 of the clip 200 and fastened to the support member 400 as described above, the clip 200 is coupled to the support member 400, The clip 200 coupled to the deck 100 may secure the deck 100 to the support member 400. As a result, since the deck 100 is fixed using the clip 200 and the nails and screws are not directly stuck to the deck 100, it is possible to prevent the deck 100 from being damaged.

The two adjacent decks 100 of the plurality of decks 100 are separated from each other by a predetermined distance D (see FIG. 2) so that the fixing means 300 can be separated from the clip 200 for replacement of the deck 100 ). That is, the clip 200 and the deck 100 can be separated from the supporting member 400 by separating the fixing means 300 through the space between the adjacent two decks 100 spaced apart by a predetermined distance D.

FIGS. 7 to 9 are sectional views sequentially illustrating the assembling process of the deck assembling structure according to the embodiment of the present invention, and the assembly process of the deck assembling structure according to the present embodiment will be described with reference to FIG. At this time, two decks 100 adjacent to each other among a plurality of decks 100 are defined as a first deck 110 and a second deck 120, and an assembling process will be described.

7, after the first deck 110 having the first concave groove 140 recessed in the side thereof is disposed on the supporting member 400, the clip 100 is inserted into the first concave groove 140, 200 are inserted.

Next, as shown in Fig. 8, the clip 200 is coupled to the supporting member 400 by the fixing means 300. Then, as shown in Fig. The fixing means 300 is inserted into the through hole 230 in the clip 200 to couple the clip 200 to the support member 400 so that the through hole 230 is in contact with the first protrusion 210 And is formed close to the second projection 220. Therefore, the through hole 230 can be exposed to the outside as much as possible without being covered by the first concave groove 140 of the first deck 110, so that the fixing means 300 can be easily inserted into the through hole 230 . The through hole 230 may extend away from the first protrusion 210 as it is further away from the first surface of the support member 400 (toward the upper side). That is, the through hole 230 can be inclined. Therefore, when the fixing means 300 is fastened to the support member 400, a force acts in the direction of the first deck 110, and as a result, the clip 200 is coupled to the support member 400, The first deck 110 can be firmly fixed by pressing the side surface of the deck 110.

Next, as shown in FIG. 9, the second deck 120 having the second concave groove 150 recessed to the side is disposed on the supporting member 400. At this time, the second projection 220 of the clip 200 is inserted into the second concave groove 150.

By repeating the above-described assembly process, the deck 100 can be sequentially fixed along the longitudinal direction of the support member 400.

FIG. 10 is a sectional view of a deck assembling structure according to another embodiment of the present invention, and FIG. 11 is a perspective view of a clip of a deck assembling structure according to another embodiment of the present invention.

10 to 11, the deck assembling structure according to another embodiment of the present invention includes an elastic body 500 capable of elastically deforming at the distal end of the first protrusion 210 or the distal end of the second protrusion 220 . Since the elastic body 500 is provided at the end of the first protrusion 210 or the end of the second protrusion 220, the elastic body 500 finally comes into contact with the concave groove 130 of the deck 100. At this time, the elastic body 500 is pressed between the first and second protrusions 210 and 220 and the concave groove 130, and is elastically deformed so that the thickness thereof decreases (refer to FIG. 10A). Thereafter, when the supporting member 400 and the deck 100 are thermally expanded according to the temperature change, the coefficient of thermal expansion of the supporting member 400 (the square pipe) formed of metal is larger than the coefficient of thermal expansion of the deck 100 formed of wood, In particular, as viewed from the longitudinal direction of the support member 400, the support member 400 expands more than the deck 100. Therefore, there is a risk that the first and second protrusions 210 and 220 of the clip 200 and the concave groove 130 of the deck 100 are separated from each other. However, the deck assembly structure according to another embodiment of the present invention is configured such that the elastic body 500 provided at the ends of the first and second protrusions 210 and 220 are elastically deformed to increase in thickness, (See Fig. 10 (b)). As a result, even if a temperature change is severe and a difference in thermal expansion occurs between the deck 100 and the supporting member 400, the clip 200 can firmly fix the deck 100.

FIG. 12 is a sectional view of a deck assembling structure according to another embodiment of the present invention, and FIG. 13 is a perspective view of a clip of a deck assembling structure according to another embodiment of the present invention.

12 to 13, the deck assembling structure according to another embodiment of the present invention includes a rotating means 600 at the end of the first main protrusion 211 and at the end of the second main protrusion 221 . The rotating means 600 is provided at the distal end of the first main protrusion 211 and at the end of the second main protrusion 221 and thus finally comes into contact with the main concave groove 131 of the deck 100. Therefore, when the deck 100 is thermally expanded in the longitudinal direction according to the temperature change, the rotating means 600 rotates in contact with the main concave groove 131, so that the deck 100 can freely thermally expand in the longitudinal direction. As a result, even if the deck 100 is expanded in the longitudinal direction, no stress is generated in the deck 100 due to the rotating means 600, thereby preventing the deck 100 from being damaged due to thermal expansion of the deck 100 itself .

In addition, an elastic member 650 capable of elastic deformation may be provided on the outer surface of the rotating means 600. Since the elastic member 650 is provided in the rotating means 600, it finally comes into contact with the main concave groove 131 of the deck 100. The elastic member 650 is positioned between the elastic member 650 and the concave groove 130 of the deck 100 so that even if there is a difference in thermal expansion between the deck 100 and the support member 400, (See Fig. 12 (b)), the clip 200 can firmly fix the deck 100. As a result,

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
