DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing structure for reinforcing an inner peripheral edge of an opening formed in a panel.

2. Description of the Related Art Generally, in order to form an opening for a window, an inspection port or an opening for ventilation in a metal panel such as an enamel panel constituting a wall surface of a unit bathroom,
First, as shown in FIG. 6, corner holes 4a are formed at positions corresponding to the four corners of the opening to be formed in the panel 4, and then the portions indicated by broken lines in the figure are connected so as to connect these corner holes 4a. Was cut with a jigsaw. With this,
The panel 4 has an opening 5 of a desired size as shown in FIG.
However, if the opening 5 is formed in the panel 4 in this way, the strength of the panel 4 is reduced and the thickness of the panel 4 itself is thin, so that a window frame or the like cannot be directly attached here. Was. Therefore, it was necessary to reinforce this opening 5. Conventionally, to reinforce this opening 5, the opening 5
In this case, reinforcing piers 11a and 11b having a length corresponding to each side are prepared, and the piers 11a and 11b are attached with an adhesive along the periphery of the opening 5 of the panel 4 as shown in FIG. Further, as another method for reinforcing the opening formed in the panel, there is one disclosed in Japanese Patent Application Laid-Open No. 9-112129. As shown in FIG. 9, a corner member 12 is attached to the back side of each corner of an opening (not shown) opened in a panel (not shown), and the inside of each side of this opening is formed. Thus, a side member 13 having a length of one side of the opening and having a cross-sectional shape capable of being fitted into the inner periphery of one side is fitted and engaged with the corner member 12.

In the above-described conventional reinforcement of a panel opening, first, a reinforcing bar is pasted in a frame shape along a peripheral edge of the panel opening by cutting the reinforcing bar into a predetermined length. Must be aligned with the periphery of the opening of the panel, and then fixed to this panel with an adhesive.
Since the workability is poor and the reinforcing bar is only bonded to the back surface of the panel, there is a problem that the strength is weak. Further, as shown in FIG. 9, in the case of using a corner member and a side member to reinforce the opening, the corner member is positioned on the back side of each corner of the opening and bonded with an adhesive. After the drying, the four side members must be fitted into the inner periphery of the opening, and this also has a problem that the workability is poor as in the case described above. An object of the present invention is to solve the problems of the above-described conventional panel opening reinforcing structure.

In order to solve the above-mentioned problems, the invention according to claim 1 of the present invention comprises a reinforcing structure for reinforcing the inner peripheral edge of an opening formed in a panel, and a reinforcing structure for the panel opening. A corner member engaging with the corner portion and a side member whose both ends are connected and fixed to the corner member. The corner member is provided with a locking piece protruding from one side of a substantially L-shaped main body when viewed from the side so as to have a predetermined gap with the corner side surface of the main body. It is substantially equal to the length of one side, and is connected and fixed to the corner member so that the panel can be attached to the inner periphery of the opening of the panel in a frame shape, thereby reinforcing the inner peripheral edge of the opening. Features.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on illustrated embodiments. In the drawing, the same functional components as those shown as the conventional example are denoted by the same reference numerals.
Generally, in order to form an opening for a window, an inspection port or an opening for ventilation on a metal panel such as an enamel panel constituting a wall surface of a unit bathroom, first, as shown in FIG. Corner holes 4a were formed at positions corresponding to the four corners of the opening 5 to be formed, and then the portions shown by broken lines in the figure were cut with a jigsaw so as to connect the corner holes 4a. As a result, an opening 5 having a desired size is formed in the panel 4 as shown in FIG. 7, but when the opening 5 is formed in the panel 4 in this manner, the strength of the panel 4 is reduced, and Since the thickness of the panel 4 itself was thin, a window frame or the like could not be directly attached here. Therefore, the opening 5 needs to be reinforced.
The present invention is used when reinforcing the opening 5 formed in the panel 4 as described above. FIG. 1 is a perspective view showing a structure for reinforcing a panel opening according to the present invention. As shown in the drawing, in the reinforcing structure of the present invention, two members, a corner member 1 and a side member 2 screwed to the corner member 1, are used. As shown in the enlarged view of FIG. 2, the corner member 1 has a main body 1 a in which rectangular parallelepipeds are connected in an L-shape, and a substantially rectangular plate-like engagement protruding from one side of the main body 1 a. 1b, and is made of synthetic resin or metal. The locking piece 1b protrudes from the inner corner 1e of the main body 1a so as to have a predetermined gap (substantially equal to the thickness of the panel 4) with the corner side surface 1d of the main body 1a. A screw hole 1c for screwing is provided on a surface adjacent to the main body 1a at a right angle in a direction penetrating the main body 1a. The side member 2 is a long member having a constant cross-sectional shape as shown in the perspective view of FIG. 1 and the cross-sectional view of FIG. 3, and is substantially equal to the length of one side of the opening 5 formed in the panel 4. It has dimensions. The side member 2 is manufactured by extrusion molding of, for example, aluminum or a hard synthetic resin, and has insertion holes 2c for screw insertion at both ends. Reference numeral 2a denotes a step formed in the longitudinal direction of the front surface, and 2b denotes a rib which is similarly provided on the rear surface in a rib shape. Next, a procedure for reinforcing the panel opening 5 using the above members will be described. First, as shown in FIG. 7, a panel 4 having an opening 5 of a desired size is prepared. Then, as shown by an arrow in FIG. 2, the corner member 1 is inserted into the corner 5a of the opening 5 of the panel 4 so that the panel 4 is sandwiched between the main body 1a and the locking piece 1b. Insert.
As a result, the corner member 1 is locked to the corner 5a of the opening 5 so as to cover the corner hole 4a formed in the corner 5a of the opening 5. In this way, the corner members 1 are attached to the four corners 5a of the opening 5 respectively.
When the corner member 1 is attached, if silicon for waterproofing is applied to the inner edge of the opening 5 in advance,
Even when the corner member 1 and the panel 4 are loosely fitted, the corner member 1 can be temporarily held at a predetermined position on the panel 4 until a fixing operation described later is completed, which is convenient. Next, the adjacent corner members 1, 1
A side member 2 having a length between the corner members 1 and 1, that is, a length corresponding to one side of the opening 5 is inserted from the inside of the opening 5 so as to be bridged therebetween. Then, the screw 3 is inserted into the screw hole 1 of the corner member main body 1a through the insertion hole 2c of the side member 2.
c, the both ends of the side member 2 are integrally connected and fixed to the corner member 1. In this way, the side members 2 having the corresponding lengths are attached along the four sides on the inner periphery of the opening 5. Thereby, the corner member 1 and the side member 2 are connected to each other, and are attached in a frame shape to the inner peripheral edge of the opening 5 as shown in FIG. At this time, the corner members 1 are connected to each other via the side members 2 and the inward movement of the opening 5 is prevented, so that the engagement between the locking piece 1b and the panel 4 sandwiched between the main body 1a is prevented. There is no danger that the gaps will come off.
As described above, in the reinforcing structure of the panel opening of the present invention,
The inner peripheral edge of the opening 5 is reinforced by inserting the corner member 1 into the corner 5a of the opening 5 formed in the panel 4 and connecting and fixing the side member 2 to the corner member 1 with the screw 3. is there. Then, for example, a window frame 8 as shown in FIG. 5 is attached to the opening 5 reinforced in this way, so that the fixed and held state is ensured. When it is necessary to close water leakage from the periphery of the opening 5 in a unit bath or the like, the space between the side member 2 and the panel 4 may be appropriately closed with silicon 7 or the like as shown in FIG. If there is a possibility that the cut edge of the panel opening 5 may be rusted, a rust preventive material may be applied to the cut edge of the opening 5 in advance before the above operation. In FIG. 4, reference numeral 6 denotes a reinforcing spacer that is attached to an appropriate position of the side member 2 to improve the strength. In the above description, an example in which the side member 2 is connected to the corner member 1 with the screw 3 is shown. However, the side member 2 may be integrally connected and fixed to the corner member 1 so as not to be displaced. May be connected by means of (1). In the illustrated embodiment, the panel 4 is divided into two so that the opening 5 can be easily formed, and the backing material 4b is additionally provided on the back surface in order to improve the flatness and heat insulation. The shape and structure of the panel 4 in which the opening 5 is reinforced may be of any shape, and needless to say, the present invention is not limited to the illustrated one.

As described above, in the panel opening reinforcing structure of the present invention, there is no step of bonding members for reinforcement, so that there is no need to wait for drying, and work can be performed efficiently. Further, since the side members are connected and fixed to the corner members with screws or the like, there is an effect that errors do not occur in assembly dimensions and a window frame or the like can be assembled with high accuracy.
