The first frame 110, the second frame 120, the first connecting member 130, and the second connecting member 160 according to an embodiment of the present invention may be made of a steel material. During the assembly process of the first frame 110, the second frame 120, the first connecting member 130, and the second connecting member 160, there is a risk of causing scratches while colliding with each other.

When the scratch occurs, the strength of the first frame 110, the second frame 120, the first connecting member 130, and the second connecting member 160 decreases as rust occurs around the scratch. There is.

To prevent this, at least one of the first frame 110, the second frame 120, the first connecting member 130, and the second connecting member 160 according to an embodiment of the present invention is It may be coated with a protective film, a protective material, or the like.

The above-described connection device for a deck support frame according to an embodiment of the present invention has the following effects.

Looking at the conventional deck installation process, the joist is installed in the horizontal yoke by welding the horizontal yoke (the first frame) and the joist (the second frame).Because the welding process uses high temperature heat, There is a problem that increases the risk of fire occurrence.

In particular, decks made of wood, synthetic wood, and the like can easily catch fire, and there is a problem that the risk of fire increases further as trees and grasses are located around areas such as hiking trails and pensions.

In addition, when the lateral yoke and joist are welded as in the conventional deck installation process, there is a problem in that the thermal load cannot be absorbed. In the deck installation process, various materials having different coefficients of thermal expansion are used, and thermal loads are generated as the coefficients of thermal expansion are different for each material. When the lateral yoke and joist are welded, there is a problem that a part of the deck system, such as a welded area and a weak area of the deck system, is damaged as the welding area is fixed so that the thermal load cannot be absorbed.

However, the connecting device for a deck support frame according to an embodiment of the present invention may not proceed with a welding process as the first frame and the second frame intersecting each other are connected through the connection part. Through this, the connecting device for a deck support frame according to an embodiment of the present invention has an advantage of simplifying work while preventing a fire that may occur in a welding process.

In addition, the connecting device for a deck support frame according to an embodiment of the present invention is coupled to the first frame and the second frame through the first connecting member and the second connecting member, without performing a welding process, by thermal load. It has the advantage of absorbing thermal loads while preventing damage to parts of the deck system, such as welding areas and weak areas.

In general, looking at the process of installing the deck, a section in which the deck is arranged in a straight line and a section in which the deck is arranged while forming a curvature are mixed. However, if the horizontal yoke (first frame) and joist (second frame) are welded as in the prior art, the position of the horizontal yoke (first frame) and joist (second frame) fixed by welding cannot be modified. Accordingly, there was a problem that it was difficult to install the deck to be arranged while forming a curvature.

However, the connecting device for a deck support frame according to an embodiment of the present invention provides a first connection member and a second connection through a rotating protrusion narrower than the width of the expansion part of the insertion hole and a fixed protrusion that is wider than the width of the expansion part of the insertion hole. As the members are coupled, the second connection member can be rotatably coupled to the first connection member.

A connecting device for a deck support frame according to an embodiment of the present invention is provided with respect to a first frame (horizontal yoke) coupled to the first connecting member by rotatably coupling the second connecting member to the first connecting member. It is possible to rotate the second frame (joist) coupled to the second connecting member.

Through this, the connecting device for a deck support frame according to an embodiment of the present invention has the advantage of being able to easily install a curved deck while easily modifying the relative position of the second frame with respect to the first frame according to the curvature of the deck.

In the above, although the present invention has been described in detail with reference to a preferred embodiment, the present invention is not limited to the above embodiment, and various modifications may be provided within the scope of the present invention. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
