Description

  The present invention relates to a door frame structure that is assembled and configured without welding a frame that is a framework of a door panel.

  In order to partition a large space of a building, a partition device is frequently used, and the partition device is arranged so that the partition panel is connected to a vertically standing stud and does not fall down. Similarly, in the case of a low partition for partitioning a private small space, panels are connected and arranged with studs in between. And such a panel is comprised by filling core materials, such as a paper core, in a metal frame and sticking a surface material on both sides.

  There are various sizes and shapes of the above panels, but the metal frame that forms the frame of the panel is a rectangle, and both vertical bars, upper bars, and lower bars are framed. Middle rail is used. These crosspieces are welded to form a frame having high strength and rigidity. By the way, when each beam is welded, it must be positioned correctly at the time of assembling, and care must be taken not to cause poor welding.

  Therefore, it must be a skilled worker who is accustomed to welding, but it requires man-hours for assembly work such as the positioning work of each beam, and the cost is inevitably high. In this case, the strength as a frame body is lowered. In addition, in the frame to be welded, distortion occurs due to heat during welding, and the frame to be assembled cannot be twisted to form an accurate rectangle, so that the surface material can be attached in a later process. It will also be a hindrance.

On both side pieces (f) and (f) of the connecting member (c) having a U-shaped cross section, fitting projections (g) and (g) are provided protruding outward. These fitting holes (e), (e) and fitting projections (g), (g) can be easily made by pressing, and as shown in FIG. ) And (b) are connected via a connecting material (c).

  That is, in the state where the U-shaped cross-section bars (A) and (B) are butted together, the U-shaped cross-section connecting material (C) is fitted, and the fitting holes (e), (e) are fitted with projections ( (G) and (g) are fitted and connected. In this way, in order to connect both bars (b) and (b) using the connecting material (c), the connecting material (c) is fitted and fitted to the bars (b) and (b) of the U-shaped cross section. The projections (G) and (G) must be fitted into the holes (e) and (e). At this time, the side pieces (d) and (d) It must bend and deform outward, and both side pieces (f) and (f) of the connecting material (c) must bend inward. Therefore, it is not easy to fit the connecting member (c) to the crosspieces (b) and (b).
