Description

Joint structure of rectangular tube for landscape structure and construction method using same {JOINT STRUCTURE OF SQUARE PIPE AND METHOD FOR CONSTRUCTING USING THE SAME}

The present invention is to install the connecting plate in a state in which the two pipes to be joined to each other, and after the initial welding (weld welding) of the joint through the opening hole formed in the connecting plate, it is possible to temporarily fix the two pipes by separating the connecting plate And the joint structure of the rectangular tube for landscape structure, which is to be finished by final welding (main welding) of the non-welded part of the joint in the state of temporary connection to several pipes forming the landscape structure, and the construction method using the same It is about.

To connect the square tubes that form the landscape structure,

Conventionally, one end of a plate in the form of a plate is welded to an inner surface of one pipe and the other end is exposed to the outside.

After the other pipe is inserted into the other end exposed, the joints of the two pipes are welded.

A plurality of pipes connected in this form forms a landscape structure.

As the operator performs the welding process directly and welds one end of the plate-shaped plate in one pipe, it is inevitably changed from the initial set position, and in particular, the deformation of the plate due to the heat conduction by the welding and the difference in the cooling rate is inevitable. no,

When the other pipe is fitted to the other end of the deformed plate, there is a problem such that it does not fit properly and is fitted or shifted at all.

If it is forcibly inserted or displaced, it may not match the original design length before construction.

In addition, as a structure for establishing the landscape structure formed by the mutually connected rectangular tube, when at least two anchor installation frames, such as `` anchor mounting frame '' is installed in the Republic of Korea Patent Publication No. 2001-0095915 (2001.11.07) Both ends of the tubular structure do not fit each of the two anchor installation frame to remove the anchor after the new anchor construction, or after the removal of the anchor installation frame should be installed a new anchor installation frame.

At this time, due to factors such as shortening the construction air and reducing the construction cost, there is a problem in that the construction of a new anchor after simply removing the anchor only results in poor construction.

In the conventional joint structure, after the final welding of the two pipes (main welding) and the final welding of another pipe connected thereto, the final welding between the plurality of pipes forming the landscape structure is completed. It is installed on the anchor installation frame, or pre-installed on the anchor installation frame installed in one of two places, the final welding between the pipes is made sequentially,

As a result, after the final welding of the last pipe, there is a case where the joint surface between the pipe and the anchor installation frame installed on the other one does not coincide with each other.

In order to solve the above problems, the joint structure of the rectangular tube for landscape structures according to the present invention,
