Description

[Detailed description of the invention] (Field of industrial application) The invention relates to an inner frame of a panel.
Specifically, the invention relates to inner frames of panels used for exterior walls, partition walls, etc.

(Prior Art) Conventionally, as shown in Fig. 1, the inner frame of a panel used for an exterior wall or a partition wall is made by aligning the inner frame A with the upper and lower frames and side frames of front and back panels forming the outer skin of the panel. It was manufactured by welding the corner R of four U-shaped frames a so that they could be installed together.

However, manufacturing the inner frame by welding requires means such as sanding,
For this reason, the manufacturing process was time consuming, which made it impossible to work efficiently, and the inner frame was particularly distorted by the welding heat, which was a major cause of hindering quality stability.

In addition, in the outer peripheral frame of a general panel, a long groove-shaped frame a is used, and by providing a notch in the flange and bending at this part, some corner R can be made into a series. However, even if special technical means are required for other connections, or notches are provided at bent parts, stress will be concentrated in those areas and the formation of the outer skin will not be possible. It was a hindrance.

(Problems to be solved by the invention) The present invention was created based on a completely new concept in view of the above-mentioned actual situation, and its purpose is to solve the problem without using any welding means.
To provide an inner frame that can be easily manufactured simply by bending means, does not take much time to manufacture, and has stable quality without thermal distortion.

(Means for Solving the Problems) In order to solve the above problems, the technical means adopted by the present invention is that a side frame is formed around the outer periphery of the front and back sides of the panel. In the inner frame, the inner frame is formed by bending an elongated frame member with a groove-shaped cross section into a pair of U-shaped unit frames, and the bent portion includes opposing portions of both rising pieces. A V-shaped notch is formed from the lower edge to the upper edge, and an upward U-shaped notch is integrally formed on the lower edge to form a bending allowance, and the elongated groove-shaped frame member is By bending the oblique edges of the V-shaped notch in the direction of the bending allowance, each side of the unit frame can be bent in the direction of the upper and lower frames and side frames of the front and back panels forming the outer skin of the panel. The reason lies in that the inner frame of the panels is constructed by placing them facing each other on the inside.

(Function) By adopting the above-mentioned technical means, a uniform U-shaped unit frame can be formed extremely easily by simply bending the bending allowance of the elongated U-shaped frame by hand. Therefore, it is possible to efficiently manufacture an inner frame that is always highly reliable and of stable quality, and it is possible to manufacture panels without any trouble.

(Example) An example of the present invention will be described below with reference to the accompanying drawings. That is, in FIGS. 2 to 7, reference numeral 1 denotes an elongated groove-shaped frame member that serves as a constituent base material of the inner frame A, and a rising piece flange 2 of the groove-shaped frame member 1 is provided with preset grooves. An upwardly U-shaped bending allowance 3 is cut out at the lower edge of the opposing portion, and a V-shaped notch 4 is integrally formed from the bending allowance 3 to the upper edge of the rising piece 2. Reference numeral 5 denotes a U-shaped unit frame, and the unit frame 5 bends the elongated groove-shaped frame member 1 into the V-shaped notch 4 through a bending allowance 3 formed in the upright piece 2 thereof. The unit frame 5 is formed by bending the edges 4a, 4a in opposing directions.
The front plate 7 and the back plate 8 forming the outer skin of the panel 6
An inner frame A of the panel 6 is configured by opposing the upper and lower frames (not shown) and the side frames 7a and 8a.

Next, in order to manufacture the inner frame A configured as described above, first, as shown in FIG. , and this fold line 1
0, 10 and both side edges 9a, 9a,
A bending allowance 3 and a V-shaped notch 4 are integrally punched out using a press or the like at preset opposing portions. Next, the both side edges 9a, 9a are bent in the same direction along the folding lines 10, 10 to form the elongated groove-shaped frame member 1, and then the bending allowance 3 is bent along the diagonal of the V-shaped notch 4. By manually bending the edges 4a, 4a in opposite directions, a U-shaped unit frame 5 as shown in FIG. 6 is formed in accordance with the shape of the panel. In this case, a fan-shaped gap 11 as shown in FIG. 5 is formed at the corner of the folded bending allowance 3, but this portion cannot be formed by simply bending the groove-shaped frame member 1. This prevents the beveled edges 4a of the rising pieces 2 from colliding with each other and avoids stress concentration on the inside, and by sealing this area, even when the panel 6 is used as an exterior wall, water will not leak out from the doorway of the panel. Since the infiltration can be prevented, even if a void 11 is formed in the bending allowance 3, the function of the panel will not be adversely affected.

As shown in FIGS. 6 and 7, the U-shaped unit frame 5 manufactured by the method described above has the upper and lower frames (not shown) and side walls of the front and back panels 7 and 8 that form the outer skin of the panel. It is used as the inner frame A of the panel by placing it oppositely along the frames 7a and 8a, but in this case, when manufacturing the panel, a core material 12 such as a honeycomb core is filled and the inner frame A There is no need to explain in detail that the core material 12 and the front and back plates 7, 8 are bonded together using a hot press.

(Effects) As is clear from the above embodiments, according to the present invention, since the inner frame is constructed by simple bending means without using welding means, the following advantages are achieved compared to the conventional one: This produces particularly remarkable effects.

Since no welding means is used, there is no distortion in the manufactured inner frame, resulting in products of consistently stable quality and high reliability.

Coupled with the fact that no welding means is used, no sanding work is required, which shortens the manufacturing time and enables efficient work.

Since the inner frame can be manufactured by a simple bending means, the manufacturing work is simplified, and even those who do not require special welding techniques can easily manufacture the inner frame, so that productivity can be significantly improved.
