Description

Device for deck connection}

The present invention relates to a deck connection device, and more specifically, to improve assemblyability and minimize expansion and contraction of deck materials, as well as to improve durability and facilitate maintenance after construction.

In general, as interest in eco-friendliness increases, deck roads using flat-type wooden decks are being built on the floors of various places such as hiking trails, trails in parks, sidewalks formed around lakes, and terraces of country houses or pensions. ) are being installed in large numbers.

Deck road refers to a pedestrian path made by continuously arranging block-shaped decks that are mainly manufactured using synthetic wood, natural wood, or various synthetic resins.

This type of deck road is mainly installed on a separate sidewalk outside the roadway of a bridge, on a footbridge manufactured as a bridge for pedestrians only, or on hiking trails or walking trails in mountains or parks.

Conventionally, in order to fix wooden deck plates, the fixing piece is directly penetrated and then joined to the base square pipe, but there is a problem in that cracks or splits occur due to the fixing piece during the construction or replacement process due to carelessness.

In order to prevent such splitting, the installation structure of the conventional deck rod is known in Public Utility Model No. 20-2014-0001877, 'Clip for Composite Wood Deck'.

That is, coupling grooves for connecting clips are formed on both sides of the synthetic wood deck along the longitudinal direction, and the clip has a flat plate portion whose both ends are inserted into the coupling grooves of each synthetic wood deck to be coupled, and a central portion of the lower surface of this flat portion. A partition portion is provided that protrudes vertically.

A fastening hole for attaching a screw is penetrated in the center of the flat part of the clip.

Therefore, when installing a composite wood deck using clips formed in this way, first, a base such as a steel beam or support beam is installed at regular intervals on the floor of the installation location where the walkway is to be installed.

Then, after the diaphragm is placed at the bottom on the installed base, the clip is fixed to the base by inserting a screw into the fastening hole of the clip and fastening it to the base, and then connecting grooves of the synthetic wood deck are made on both sides of the flat part of the clip fixed to the base. By sliding and moving the synthetic wood deck in a aligned state, the synthetic wood deck is joined to the flat part of the clip.

Then, each synthetic wood deck is coupled to both ends of the flat plate portion of the clip.

However, according to this conventional wood deck installation structure, the clip is fixed with a piece to the base member (aka square pipe) for installing the composite wood deck, and the protrusions formed on both sides of the upper surface of the clip are connected to the joint formed on both sides of the composite wood deck. Because it is a work structure that involves inserting a screw into a groove and fastening a screw, it has the disadvantage of being time-consuming and inconvenient as it requires drilling fastening holes in each pipe one by one and fastening screws at the work site.

In particular, in the prior art, a fastening hole must be drilled in the square pipe, but the joint position cannot be specified, so the fastening hole cannot be formed at the same time when manufacturing the square pipe. For safety, the square pipe is made of a sturdy material, so the square pipe must be connected directly to the pipe at the work site. It is very difficult to form fastening holes.

On the other hand, the conventional wooden deck connection structure described above also had a problem in that the connection parts were not finished beautifully, thereby reducing marketability.

Domestic utility model publication number 20-2014-0001877 (publication date April 2, 2014) Domestic Patent Registration No. 10-1200530 (registration date: November 6, 2012)

The purpose of the present invention is to provide a deck connection device with excellent economic efficiency by improving assemblyability and preventing cracks or splits from occurring due to fixing pieces during construction or replacement.

Another object of the present invention is to provide a deck connection device that not only minimizes expansion and contraction of deck materials, but also improves durability and facilitates maintenance after construction.

To achieve this purpose, the configuration of the present invention includes a base square pipe (10) disposed at regular intervals on the floor of the installation location,

Deck boards (20) located sequentially on the upper part of the base square pipe (10) and having upper and lower fitting grooves (21) and lower fitting grooves (22) concavely dug in the longitudinal direction at the upper and lower ends of both sides, respectively,

A lower connecting member (30) with a fitting protrusion (31) protruding to fit into each of the lower fitting grooves (22) on both sides of the deck boards (20) and fixed to the base square pipe (10) by a fixing piece (32),

An upper connecting member (40) in which a hook projection (42) is integrally formed between the assembly pieces (41) fitted into the upper fitting grooves (21) on both sides of the deck boards (20), respectively,

A fastening member located in the space provided between the deck boards 20, and in which the hook engaging portion 51 is integrally bent to prevent the hook projection 42 of the upper connecting member 40 from being separated from the vertically inserted state. It is characterized in that it is composed by including (50).

The fastening member 50 is made of a metal plate of a certain thickness, and a support portion 52 is integrally bent and molded at the lower end to be inserted between the lower connection member 30 and the bottom of the deck board 20.

In addition, the upper connecting member 40 is made of a transparent or translucent synthetic resin material, and a plurality of beads 60 having a glass bead structure may be incorporated therein.

According to the present invention, the joints of the deck boards can be constructed in a state that is strong while minimizing expansion and contraction through the lower connection member with a ∪-shaped cross-sectional structure and the upper connecting member with a ∩-shaped cross-sectional structure.

Therefore, the durability of the deck is improved and maintenance after construction is easy, and it is economically efficient by preventing cracks or splits due to the fixing pieces during the construction or replacement process.

In addition, the beads made of glass ensure visibility to check whether the deck board is installed even in dark environments at night or in heavy rain, thereby preventing various safety accidents while walking and providing excellent safety.

In addition, the simple aesthetics in the assembled state improves marketability and reliability.

Figure 5 is a perspective view of the main part showing a state in which the upper connecting member is coupled to the fastening member, and Figure 6 is a partially enlarged view of Figure 3.

Figure 7 is an exploded front view showing the process of assembling the entire structure of the present invention.

As shown in the drawing, the base square pipes 10 are arranged side by side at regular intervals on the ground to form a deck rod, and the deck boards 20 are placed one after another on the top of the base square pipes 10, and the upper connection member 40 ) and the lower connection member 30 and fastening member 50.

The base square pipe 10 may be selected from a square pipe made of metal or a square piece of wood.

The deck boards 20 are made of natural wood or synthetic wood, and the upper surface is repeatedly formed with irregularities in the longitudinal direction to prevent slipping, and upper fitting grooves 21 and lower fitting grooves 22 are concave at the upper and lower ends of both sides, respectively. It is dug out in the length direction.

The lower connecting member 30 has fitting protrusions 31 protruding upward on both sides to be inserted into the lower fitting grooves 22 on both sides of the deck boards 20 and extending longitudinally in an approximately ∪ cross-sectional shape. It is cut to approximately the same length as the board 20, placed on the upper part of the base square tube 10, and firmly fixed to the base square tube 10 by a fixing piece 32.

In addition, the upper portions of the deck boards 20 are finished with the joints connected to each other through the upper connecting member 40.

The upper connecting member 40 extends in the longitudinal direction with an approximately It is cut to approximately the same length as the board 20 and the deck boards 20 on both sides are connected symmetrically to the lower connecting member 30.

At the center of the bottom of the upper connecting member 40, a hook projection 42 is integrally formed between the two assembly pieces 41.

The hook protrusion 42 is formed into an approximately arrowhead shape with a sharp end and a catching portion formed in the middle to prevent the hook from coming off while being coupled to the fastening member 50.

When the deck boards 20 are installed, a space of a certain size is formed between them. After the fastening member 50 is positioned at this space, it is fastened to the hook projection 42 of the upper connection member 40 to This prevents the connection member 40 from being separated.

The fastening member 50 is made of a metal plate of a certain thickness, and the hook engaging portion 51 is integrally bent at the upper center to prevent the upper connecting member 40 from coming off while being coupled with the hook protrusion 42. It will be prevented.

Since the hook latching portion 51 is bent and formed from a metal plate, it has appropriate elasticity, so when the hook protrusion 42 is pressed with a strong force from the upper part, the gap widens due to its own elasticity and then returns again, forming a bond as shown in Figure 6. The status quo can be maintained.

And, at the lower end of the fastening member 50, a support portion 52 is integrally bent and molded to fit between the lower connecting member 30 and the bottom portion of the deck board 20.

Accordingly, the hook protrusion 42 of the upper connecting member 40 is fitted and coupled to the hook engaging portion 51, and the support portion 52 of the fastening member 50 is connected to the lower connecting member 30 and the deck board 20. Since it is fixed by inserting it between the bottom parts of the , it is possible to maintain a solid fastening condition overall.

Therefore, since the pieces are not directly fastened to the wooden deck, contraction and expansion of the deck material is minimized, and deck damage does not occur even during replacement after construction, resulting in excellent durability and compatibility.

In addition, since it is not structured to be directly fastened to the fixed piece deck material during construction work, direct damage to the product is prevented, the finish is improved, and maintenance is easy.

On the other hand, as shown in FIG. 6, when the upper connecting member 40 is molded from a transparent or translucent synthetic resin material, a large number of beads 60 with a glass bead structure are incorporated into the upper connection member 40, so that even small lights around it make the glass visible. The beads 60 serve to reflect or refract the light.

Therefore, by securing visibility to check whether the deck board is installed even in a dark environment at night or in heavy rain, various safety accidents are prevented and safety is ensured while walking.

In addition, it has the effect of increasing the strength of the upper connecting member 40 and further improving the external aesthetics.
