Abstract

PURPOSE:To form such a panel frame as excellent in accuracy by fitting a joint in an edge of the panel frame on one side by means of welding, while fitting a joint in the panel fame on the other and welding it after being butted at a right angle. CONSTITUTION:A partial outer side of side pieces 31, 32 of a joint 3 is made contact with each inner part of side pieces 11, 12 of a panel frame on one side and locked thereto by means of welding. Next, a panel frame 2 on the other is fitted in the joint 3 from a direction being crossed at a right angle with the frame piece 1. Then, an interval between the joint 3 and those of side pieces 31, 21 and 32, 22 of the frame 2 is welded together as one body.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a panel frame that can prevent warping and deformation of panel frame pieces and can be manufactured with high precision.

[Conventional technology]

Various types of panels are used in architecture, such as exterior wall panels, roof panels, floor panels, and partition panels.

Among the second class panels, steel panel frames are shown in Figures 5 and 6.
As shown in the figure, the edges of one of the panel frame pieces that butt each other at 90 degrees are embossed to reduce the size of the grooved steel by one circumference at the end, and the edge with this drawing process is
The other panel frame piece is fitted, and the fitted portion is integrated by spot welding or the like.

[Problem to be solved by the invention]

When the edges of the grooved steel are subjected to embossment processing, the grooved steel itself becomes warped, and a bulging phenomenon occurs on the wear surface of the drawn portion. For this reason, the panel frame bodies, which are constructed by fitting each other and abutting each other at 90 degrees, are deformed, resulting in a disadvantage that accuracy is reduced.

Further, since this drawing process is performed for each member, it requires a lot of processing time, and if the sizes (lengths) are different, there is a drawback that even members that have been previously subjected to a patterning process cannot be used.

An object of the present invention is to provide a panel frame with high precision by omitting the drawing process that tends to cause deformation of the panel frame.

[Means to solve the problem]

In a panel frame in which channel steel having the required size is used and panel frame pieces cut to the required dimensions are butted against each other in a perpendicular direction to integrate them, there is a hole inside the panel frame piece at the end of one panel frame piece. A joint made by cutting out the wear on one end of a channel steel of a size to be fitted to the panel frame is fitted and welded, and the other panel frame piece that is butted at right angles is fitted and welded to the joint to form an integral piece. .

[For production]

A channel steel of a size that can fit into the channel steel is used on one side of the panel frame piece, which is cut into the required size.
A joint is interposed between the ends of both panel frames that abut at 0 degrees and are welded and fixed to each other. Then, a part of the wear portion at the end of the joint is cut out so that both the wear surfaces of the joint and the panel frame piece to be joined in a straight line are flush with each other. The end of the other panel frame piece is fitted and welded to the other end of this joint in a direction perpendicular to the other end. By using this joint, the ends of the panel frame pieces that are butted against each other can be joined easily and with high precision without applying any embossment processing.

〔Example〕

The panel frame of the present invention will be explained below based on the illustrated embodiments.

In the figure, reference numeral 1 denotes a panel frame piece made by cutting channel steel having a square U-shape in cross section into predetermined dimensions, and is mainly disposed in the horizontal direction. Further, 2 is a panel frame piece which is arranged mainly in the vertical direction, and has the same cross-sectional shape and size as panel frame piece 1, but differs only in length.

Reference numeral 3 denotes a joint made of channel steel that is sized to fit into the channel steel of panel frame piece 1.2, that is, one size smaller than panel frame pieces 1 and 2. When one end is fitted, side piece 1 of panel frame piece 1
The channel steel size of the joint 3 is determined in such a way that the inner surface of 1.12 and the outer surface of the side pieces 31.32 of the joint 3 touch each other.

At the end of the joint 3 to be inserted into the panel frame piece 1, the wear part 33 is cut out by a length equal to the length to be inserted into the panel frame piece 1. The end face of the cutout portion 34 is brought into contact with the end face of the web portion 13 of the panel frame piece 1, so that the outer surfaces of the panel frame piece 1 and the wear parts 13 and 33 of the joint 3 are flush. The length at which this joint 3 is inserted into the panel frame piece 1 is the side piece 11.1.
When fixing the part where the outer surface of the side pieces 31 and 32 of the joint 3 are in contact with the inner surface of the joint 3 by spot welding etc.,
is fixed with the required strength, and the length of the joint 3 protruding from the tip of the panel frame piece 1 is equal to or shorter than the inner length of the side pieces 21 and 22 of the other panel frame piece 2. It should be a little shorter than that.

The state in which the joint 3 is joined to the end of the panel frame piece 1 is shown in FIGS. 2 and 3. After the joint 3 is fixed to the end of the panel frame piece 1 in this way, the other panel frame piece 2 is fitted into the joint 3 from the direction intersecting the panel frame piece 1, as shown in FIG. . At this time,
Both panel frame pieces 1 and 2 are arranged to intersect at right angles and butt each other, and then this joint 3 and the side pieces 31, 21 and 32.22 of the panel frame piece 2 are spot welded to be integral.

In this way two lateral panel frame pieces 1.
1 and two vertical panel frame pieces 2.2 are assembled into a frame shape.

In this case, the joints 73 can also be provided at the ends of the longitudinal panel frame pieces 2.

[Effects of the Invention] The panel frame of the present invention uses channel steel having a required size, and in a panel frame in which panel frame pieces cut into required dimensions are butted against each other in a perpendicular direction and integrated, one panel frame piece At the end of this panel frame piece, we fit and weld a joint made by cutting out the wear at one end using channel steel of a size that fits inside this panel frame piece, and then attach the other panel frame piece that butts at right angles to this joint. Since the joints are fitted and welded into one piece, there is no need to draw the panel frame pieces made of channel steel, so there is no warping or deformation of the panel frame pieces, and the panel frame can be manufactured with high precision. Furthermore, since the joint can be applied even when the lengths of panel frame pieces are different, there is an advantage that panel frames of different sizes can be easily manufactured.
