Description

[0001]
[Industrial application fields]
The present invention relates to a large door panel configured by connecting a plurality of panels. Here, the door includes an open / close door supported by a hinge and a hanging door type door.
[0002]
[Prior art]
There are doors attached to the frontage that can be opened and closed via hinges, and doors that can be opened and closed by hanging on the upper rail. Hinged doors rarely use large door panels, but in the case of hanging doors, there are cases in which they cannot be configured with a single panel to be installed in a large frontage. For example, in the case of using a panel in which a steel plate is attached as a surface material, if the width dimension exceeds 1550 mm, the surface material does not exist and must be joined together.
[0003]
FIG. 5 shows a general hanging door, but the door panel (A) is formed by connecting two panels (B) and (B) arranged vertically. Suspension wheels (c) and (c) are attached to the upper end of the door panel, and the frontage can be opened and closed by being suspended and moved by an upper rail (not shown) provided at the upper part of the frontage. (D) in the figure is a handle. This sliding door can be a semi-automatic door that pushes open by hand and automatically closes, or it can be a fully automatic door using a motor, but the conventional large door panel (a) has a loss of appearance due to the connecting structure of the upper and lower panels. Yes.
[0004]
6 (a) and 6 (b) are conventional specific examples showing the connection structure between the panels (b) and (b), and are enlarged cross-sectional views taken along the line AA of FIG. In the case of (a), the upper and lower panels (b) and (b) are attached to the middle frame (e) of the frame by inserting joint joints (g) and screws. Of course, in order to cover the joint joint (g) and the screw head, the joint cover (chi) is fitted in the joint space. In this way, the joint cover (H) is interposed between the upper and lower panels (B) and (B), so that the appearance of the door panel (A) is poor and the panel (B) and (B) are attached to the frame. Therefore, the manufacturing cost is also increased.
[0005]
(B) The upper and lower panels (b) and (b) are brought into contact with each other, and a connecting plate (re) is applied between the panels (b) and (b) to reinforce the panel reinforcements ( ). This connection form is simple in structure, but the appearance is greatly impaired because the connection plate (re) that is screwed is exposed on the surface of the panel connecting portion.
[0006]
[Problems to be solved by the present invention]
As described above, when the door panel becomes large, the panel connection structure has the above-described problems. The problem to be solved by the present invention is this problem, and provides a large-sized door panel that does not cause unevenness in the connecting portion between the connected panels, and that has a simple connecting structure and does not impair the appearance.
[0007]
[Means for Solving the Problems]
The large door panel of the present invention is a door panel configured by connecting two or three panels, and bolts are used as connecting means. The arrangement direction of the panels may be either the vertical direction or the horizontal direction, and bolts are attached to the panel joints to tighten and connect both panels to form a large panel. Reinforcing materials are provided on the panels, and the reinforcing materials are abutted against each other and bolted together.
[0008]
Here, either bolts or nuts are pre-welded to the reinforcement. A pipe is fixed to the other frame body, and can be screwed through the pipe hole. One of the frames to which the bolts or nuts are welded is not provided with the pipe. Each frame is filled with a paper core, and a surface material is adhered to both surfaces.
[0009]
Further, in the present invention, in order to prevent the appearance of the connecting portion between the panels from being damaged, a device such as interposing a connecting member or attaching a joint is devised. That is, when the surface material to be attached to the panel is slightly misaligned between the front side and the back side, a gap will remain in the joined panel joint, but this gap will not appear on the appearance The connecting structure is covered. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
[0010]
【Example】
FIG. 1 is an embodiment showing a longitudinal section of a door panel 1, and two panels 2a and 2b are arranged vertically and connected to each other. The panel 2 has a frame as a reinforcing material around it, and a paper core 3 is accommodated in the frame, and surface materials 4 and 4 are bonded to both sides. Both panels 2a and 2b are tightened with bolts 5 and nuts 6 to form a large door panel 1, with a lifting tool for hanging on the rail at the upper end and a guide groove 7 at the lower end. 7 is fitted with a steady rest 8 that stands up from the floor.
[0011]
Both the panels 2a and 2b are fastened by the bolts, but the reinforcing members 9a and 9b provided at the upper and lower ends of the panels are bolted to each other. By the way, when both the panels 2a and 2b are bolted, the bolt 5 is previously welded to the reinforcing member 9a, and one nut 6 is inserted from the lower end of the lower panel 2b, screwed into the bolt, and tightened. Therefore, a through hole is provided in the panel 2b from the lower end to the reinforcing material 9b.
[0012]
FIG. 2 shows a case where both panels are bolted and connected, but the state of the frame is shown for easy understanding. Actually, the rectangular cores 10a and 10b are filled with the paper core 3, and the surface materials 4 and 4 are adhered to both surfaces to form the panels 2a and 2b. Bolts 5, 5,... Are welded to the lower reinforcing member 9a of one frame 10a and extend downward, and through holes are provided in the upper reinforcing member 9b of the other frame 10b to pass the bolts 5, 5,. The nuts 6, 6... Can be inserted and screwed from the lower end of the frame 10b.
[0013]
As shown in the figure, the lower frame 10b has pipes 11, 11,... Attached vertically, and the nuts 6, 6,... Pass through the spaces of the pipes 11, 11,. And is screwed onto the bolts 5, 5. At this time, the nut 6 can be fitted into the tip socket of the jig 12 having a length equal to or higher than the panel height and turned to be screwed into the bolt 5. Since the frame body 10b is provided with the pipes 11, 11,..., The paper core 3 is filled in the remaining space.
[0014]
FIG. 1 shows a large door panel 1 in which the panels 2a and 2b are connected in this way. However, if the surface materials 4, 4. The external appearance is impaired, for example, a gap is formed in the connecting portion between 2b. FIG. 3 shows a case where a gap 13 is generated between the panels 2a and 2b connected by the sticking misalignment of the surface materials 4 and 4, and not only the appearance of the connecting portion is impaired, but also the connected state is not stable.
[0015]
Therefore, the connection structure shown in FIGS. 4A and 4B can be provided so that the external appearance is not impaired by the gap 13 and stable connection is made. In (a), the connecting member 14 is bolted by being interposed between the panels 2a and 2b. However, the connecting member 14 has an H-shaped cross section, and the upper and lower ends of the panels 2a and 2b are both side pieces 15 and 15 respectively. In between. Although both the reinforcing members 9a and 9b are not strongly tightened due to the gap, the upper and lower ends of the panels 2a and 2b fitted between the side pieces 15 and 15 cover the gap 13 and are not misaligned. Will be linked.
[0016]
(B) shows the case where the joint material 16 is interposed between the two panels, and the joint material 16 has a width smaller than the panel thickness and recedes from the panel surface to form a gap 17. Yes. The edge 18 of the surface material 4 that is misaligned and protrudes from the reinforcing material 9a is bent by hitting the joint material 16 by screwing, and the reinforcing materials 9a and 9b of both panels 2a and 2b are firmly connected to each other. Tightened. And since the joint material 16 is interposed between both panels 2a and 2b and the gap 17 is left, even if a slight misalignment occurs in the joint portion, it does not stand out and the appearance is not impaired.
[0017]
In this embodiment, the case where the upper and lower panels 2a and 2b are connected to form the door panel 1 has been described, but the same applies to the case where the three panels are connected. On the other hand, not only the upper and lower sides but also the left and right sides can be arranged and connected. Also in this case, the structure of the connecting portion is tightened using a bolt as described in the embodiment. As described above, the large door panel of the present invention is configured by connecting a plurality of panels. In this case, bolts are used as the panel connecting means, and the following effects can be obtained.
