Abstract

PURPOSE:To reduce the number of operations by a method in which a flat plate having rivet holes and wire holes is bent into an angled form, and two pieces of the angled plates are combined into a pipe form and joined to each other. CONSTITUTION:Column parts 20 are set on given positions in such a way as to enable panels 10 to connect to lipped angled parts 21 to make up the column part 20. The panels 10 are placed to turn the flat panel 11 outside of room between the column parts 20 to connect the panels 10 with the column parts 20 by rivets. After all the panels 10 are attached, an electric wire 3 is passed through the parts 10 and 20 and a copper foil tape 31 is applied to the joint of the panels 10 and wall panels 35 are attached to the indoor side. Holes 22 and 23 necessary for the column parts 20 can thus be exactly formed in the flat panel 11 before forming the column parts 20 by using a turret punch or others by reducing the number of the holing operations.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillar used in a panel structure having a plurality of panels and a method for manufacturing the pillar.

[0002]

2. Description of the Related Art As a conventional pillar material for a panel structure, for example, there is one using a square pipe as shown in FIG. When the column material 1 which is a square pipe and the panel 2 are to be riveted, a rivet hole is drilled at the construction site using a drill. Also, when passing the electric wire 3 etc. through the pillar material 1,
Drill the hole 4 according to the size of the electric wire 3 etc.
Open.

[0003]

However, such a conventional pillar material has a problem that it takes a lot of time and labor because a hole is drilled at the construction site by using a drill.
In particular, when it is a hole for electric wires, it is necessary to penetrate the drill to a desired position many times to increase the hole diameter, which is a huge labor and labor. The present invention has been made by paying attention to such a conventional problem, and provides a pillar material for a panel structure capable of reducing the time and effort for making a hole during the construction of the panel structure, and a manufacturing method thereof. The purpose is to do.

[0004]

In order to achieve the above object, a pillar material for a panel structure is provided with a hole at a predetermined position of at least one of two chevron members having a chevron cross section. The chevron members are combined and joined so as to form a square pipe shape.

[0005]

After a hole for passing an electric wire or the like is formed at a predetermined position of the flat plate member, the flat plate member is bent to form a chevron member. The chevron thus formed and the chevron without holes for passing electric wires or the like are combined and joined in a square pipe shape.

As described above, by forming the pillar member by combining the two chevron members, the holes required for the pillar can be formed in the flat plate before the pillar member is formed. Therefore, a machine such as a turret punch can be used to make a hole accurately and cleanly, and the number of man-hours required for making the hole can be reduced. Especially when the panel structure is an electromagnetically shielded room and there are many rivet holes for joining the panel and the pillars in order to reduce the leakage of electromagnetic waves, the effect is very large. Is.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment according to the present invention will be described with reference to FIGS. The panel structure of this embodiment is shown in FIG.
As shown in (1), the electromagnetic wave shielded room prevents electromagnetic waves emitted from medical devices such as magnetic resonance diagnostic equipment (MRI) and electronic devices from leaking to the outside or from entering from the outside. This electromagnetic wave shielded room is configured to have a pillar material 20 and a panel 10. As shown in FIGS. 1 and 2, the column member 20 is formed of a lip-shaped chevron 21 and a normal chevron 26.

The column member 20 needs rivet holes 22, 22, ... For joining the panel 10 by rivets, and wire holes 23 for passing the wires 3 and the like. These holes 22.
As shown in FIG. 3, 23 is opened using a turret punch before bending the flat bar 25 to form a chevron. Further, the hole 24 for riveting the angle pieces 21 and 26 to each other is also opened at this time using a turret punch. In this way, after the holes 22, 23, 24 are opened, the angle pieces 21, 26 are combined and riveted together so as to form a square pipe shape. When the chevron members 21 and 26 are joined by welding or the like, the rivet hole for chevron member mutual joining is not necessary.

Usually, since a square pipe is used for the column member, a turret punch cannot be used, and a hole is manually drilled using a drill. In particular, when this is performed at a construction site or when a hole having a large diameter for passing an electric wire or the like is formed, the labor is very large. In this embodiment, the turret punch can be used to make holes, so that the hole shape is accurate and clean, and the time and effort required to make holes can be reduced.

The panel 10 has a rectangular main flat plate 11 and a peripheral plate 16 provided on the periphery of the main flat plate 11 at a right angle. This panel 10 also has a panel 1
A hole 17 for riveting with 0, 10 or the pillar 20 and an electric wire hole 18 are required. Therefore,
When the panel 10 is formed, the turret punch is used at a predetermined position on the flat plate to open the rivet holes 17 and 18 and the like, and then a portion to be the peripheral plate 16 of the flat plate is provided to form the panel.

Generally, if the length of the dipole antenna on the receiving side is set to 1/2 of the length of the dipole antenna on the transmitting side, the receiving efficiency becomes poor. Therefore, in this embodiment, the distance between the rivet holes of the pillar member 20 and the panel 10 is set to be equal to or less than 1/2 of the frequency of the electromagnetic wave to be shielded. The panel 10 and the pillar member 20 are all formed of a conductive stainless material.

When constructing the electronic shield room, first, the pillar member 20 is installed at a desired position. At this time, the pillar material 2
It is preferable to dispose the column member 20 so that the panel 10 is joined to the angled bar member 21 forming 0. This is to prevent the rivet heads for joining the chevron members from coming out on the joining surface with the panel 10 so that the joining surfaces come into close contact with each other. After that, the main flat plate 1 is placed between the pillar materials.
The panel 10 is arranged so that 1 faces the outdoor side, and the panel 10 and the pillar member 20 are riveted to each other. Rivet hole 1
Since Nos. 7 and 22 are finely opened by a turret punch, there is no burr on the peripheral edge of the hole and the adhesion between the joint surfaces is improved. Therefore, the bonding becomes strong and the effect of the electromagnetic wave shield can be enhanced.

After mounting all the panels 10,
The electric wire 3 is passed through the panel 10 and the column member 20, the copper foil tape 31 is attached to the joint between the panels, and then the wall member 35 is attached to the indoor side. In this embodiment, since the column members 20 are provided at the corners of the electromagnetic wave shielded room, as shown in FIG. 1, there is no overlap between the panels at the corners, and the width is the same as that of the panel 10, that is, the standard dimension width. The wall material 35 can be used.

Although the present embodiment relates to an electromagnetic wave shield room, it goes without saying that the present invention can be basically applied to a panel structure without being an electromagnetic wave shield room. In this case, since it is not necessary to care about the leakage of the electromagnetic machine, it is not necessary to particularly consider the adhesion between the panels and the interval between the rivet holes.

[0015]

According to the present invention, since two pillars are combined to form a pillar, holes necessary for the pillar can be formed in the flat plate before the pillar is formed. Using such a machine, it is possible to accurately and cleanly make holes, and it is possible to reduce the number of man-hours required for making holes.
