Description

  The present invention relates to an angle member for connecting panels in a warehouse, a refrigerator, a clean room, or the like.

Generally, in a warehouse, a refrigerator, a clean room, or the like, a so-called angle material having a substantially L-shaped cross section is used when the panels are angled, particularly when they are connected at right angles. As a structure for connecting the panels using the angle material, the angle material having two contact pieces that contact the connecting frame material having a narrow opening provided on the end surfaces of the panels arranged at right angles to each other is contacted. A structure is known in which a bolt penetrating the contact piece is screwed into a square nut disposed in the opening of the connecting frame member, and the connecting frame member is fastened and connected between the square nut and the angle member ( For example, see Patent Document 1).
JP-A-7-257687 (paragraph number 0016, FIG. 2)

  By the way, in a refrigerator, a clean room, and the like, airtightness is indispensable at a connecting portion between panels, and for this purpose, it is necessary to attach a packing in the longitudinal direction of the angle member.

  However, if the packing is attached to the angle member described in JP-A-7-257687 as it is, there is a problem that a gap is generated between the panel and the angle member, so that the airtightness cannot be maintained.

  In addition, it is possible to connect the panels by connecting the connecting side surfaces of the panels to the contact piece of the angle member described in JP-A-7-257687, but in this case, the head of the bolt is in contact. It will be exposed in the state which protruded to the piece, and not only the appearance beauty will fall, but there exists a possibility of contact with an operator or a storage thing. Further, in order to pass the bolt through the flat surface of the contact piece, it is necessary to position the bolt. However, since the positioning is troublesome, there is a problem that the efficiency of the panel connecting operation is lowered.

  This invention has been made in view of the above circumstances, has high airtightness, workability, and freedom during construction, and eliminates a gap between the panel and the head of the fixing screw member. It is an object of the present invention to provide an angle member for panel connection that has no protrusion.

  In order to solve the above-mentioned problems, an angle material for panel connection according to the present invention is an angle material for panel connection that connects panels that intersect each other or a panel and a wall body. Two contact pieces that contact each other along the connecting side surface are formed at an angle, and a concave groove common to the packing arrangement or the screw arrangement along the contact piece is formed on both surfaces of each of the contact pieces. At least one or more are provided (Claim 1).

  In the present invention, the angle between the two abutting pieces may be arbitrary as long as the two abutting pieces are in contact with the connected side surfaces at the intersection of the panels or the wall body. However, it is preferable that the two contact pieces are formed substantially at right angles (claim 2).

  In addition, it is preferable that the angle material of the present invention is formed of an extruded shape made of an aluminum alloy.

  According to this invention, since it is configured as described above, the following excellent effects can be obtained.

  (1) According to the first aspect of the present invention, both the surfaces of the two abutting pieces that are in contact with each other along the connecting side surfaces of both panels to be connected or the panel and the wall body are provided along the abutting pieces. Since at least one common groove is provided for packing arrangement or screw arrangement, the packing is arranged in the groove provided on the surface side that comes into contact with the panel or wall, and the groove on the other surface side is arranged. A screw head can be disposed in the groove in a state where the screw member for fixing the panel or the wall body is penetrated. Moreover, since the panels or the panel and the wall body can be connected in a state where the panels or the wall body are in contact with each other on both surfaces of the contact piece, the connection form of the panels or the panel and the wall body is possible. The degree of freedom can be increased. Therefore, it has high airtightness, workability, and freedom during construction, and has a good fit that eliminates the gap between the panel or the wall and eliminates the protrusion of the head of the fixing screw member. An angle material for connection can be provided.

  (2) According to the invention described in claim 2, by forming the two abutting pieces substantially at right angles, the angle members can be connected to the vertically connected panels or the connection state between the panels and the wall body. Since the usage form can be selected, in addition to the above (1), the usability can be further improved.

  (3) According to the invention described in claim 3, the angle material is formed of an extruded shape made of an aluminum alloy, whereby the weight and strength can be increased.
