Welding jig device for manufacturing side frame integrated with window frame of assembling panel

The present invention is used for the manufacture of a side frame for prefabricated panels disposed along the side of the prefabricated panel to strengthen the strength of the prefabricated panel, the side frame for the prefabricated panel can be manufactured in a form integrally provided with a window frame portion for forming a window At the same time, it relates to a welding jig device for manufacturing a side frame integrated with a window frame for a prefabricated panel that enables manufacturing and production of the corresponding side frame as a product of accurate and precise specifications.

Prefabricated buildings are used not only for general residential purposes, but also as buildings for various purposes, including buildings in resorts and military barracks.

Prefabricated panels are mainly used for walls, roofs, floors, etc. of prefabricated buildings, and a representative example of prefabricated panels is a sandwich panel. Hereinafter, a sandwich panel will be described as an example.

Briefly describing the structure of a general sandwich panel, the sandwich panel is made by attaching a metal plate mainly using a steel plate to both sides of an insulating material such as Styrofoam (EPS), polyurethane, or glass wool. Further, in the sandwich panel, recesses and outward protrusions for connection between the sandwich panels are formed on both sides of the metal plate, and accordingly, the sandwich panels are connected to each other through the recesses and outward protrusions to form a continuous connection.

However, since the above-mentioned conventional sandwich panel has relatively weak bearing capacity, it is usually constructed together with a frame such as a steel frame to constitute a prefabricated building. And, as the assembly tolerance between the sandwich panel and the frame increases, the structural stability and assemblyability of the prefabricated building are deteriorated, and at the same time, the sound insulation and insulation functions are also affected. In addition, as the external exposure of a frame such as steel frame and a separate finishing construction to cover it are in progress, the construction work of the prefabricated building becomes complicated and the construction period becomes longer.

In addition, when a window is formed in a prefabricated building using an existing sandwich panel, an opening for forming a window is provided in the sandwich panel, and then a separate window frame made in this way is embedded and installed in the opening provided in this way. will install In other words, as a solidly manufactured window frame is separately required for window installation, and the work of firmly bonding the provided heavy window frame to the sandwich panel is involved, the window installation work for the prefabricated building becomes relatively complicated. it was In addition, when a relatively inexpensive material is used as the material of the window frame, the structural stability of the corresponding window is lowered, and this is a result of the different structural stability and robustness of the windows for each prefabricated building.

Therefore, as the self-resistance of the prefabricated panel is strengthened, the overall strength of the prefabricated building using it can be strengthened, and the method and work process of forming a window on the wall using the prefabricated panel is more simplified, and at the same time, the window frame that forms the window There is a need for a technology that can better ensure structural stability and robustness.
