Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure between wall panels of a unit room or a floor panel and a ceiling panel, and more specifically, a connecting tool and a wall panel used for connecting them. It is related to the fixing structure with the flange of.

[0002]

2. Description of the Related Art In recent years, unit bathrooms, shower rooms, etc. have been widely adopted not only in hotels but also in general households, and each room has a panel with a flange around it. It has a structure in which a floor panel and a ceiling panel are connected to the panel. FIG. 6 shows a conventional floor panel 10.
1 shows an example of connecting and fixing a wall panel 5 and a wall panel 5, in which a floor panel 10 has a rising portion 12 and a step portion 11 formed around the floor panel 10, and the wall panel 5 has a flange 6 and a step portion 11
, And the inner surfaces thereof are aligned with each other and fixed with screws 19 or the like.

[0003]

However, in order to match the inner surfaces of the two and to fix the stepped portion 11 and the flange 6 with screws or the like, at least one worker cooperates inside and outside the wall panel 5. It was necessary and the connection was not easy. Moreover, since the unit type room is often installed in a relatively small space, it may be difficult for an operator to work outside the wall panel 5. Under these conditions, it is also possible to assemble the unit type room once in a space other than the installation place and carry it in, but this method requires that after the unit type room is assembled. The work of moving is difficult, and even if it is possible to move, since the unevenness of the foundation surface of the assembly place and the installation place is different, it is necessary to readjust the height adjusting legs provided on the floor panel 10 again. The problem remains that the work is very difficult.

For this reason, the connector 1 for hooking on the rising portion 12 of the floor panel 10 is fixed to the flange 6 of the wall panel 5, the wall panel 5 is lifted from the inside of the chamber, and the rising portion 12 and the connecting member 1 are connected to each other. A method of fitting and fixing is provided. FIG. 7 shows an example of this, in which the connector 1 having the fitting portion 2 is fixed to the flange 6 of the wall panel 5 with screws 19. However, since the head of the screw 19 projects from the surface of the flange 6, the floor panel 10
There is a new defect that a gap is created between this and the stepped portion 11.

On the other hand, FIG. 8 shows a conventional example in which the connecting tool 1 in which the bolt 20 is erected is fixed to the flange 6 of the wall panel 5 with the nut 21, but in this case, the connecting tool 1 itself is Since it projects, there is the same drawback as in FIG. 7.

[0006] And, those having these structures are the floor panel 1
A new problem occurs because the 0 side is scratched, the fit is poor, and the dimensional accuracy is not obtained. or,
In the bathroom unit, since water tightness is required, it is common to use a seal material for the connecting and fixing part, but it is difficult to use the seal material because the screw and the connecting tool protrude. The desired sealing effect cannot be expected.

For this reason, a method has been adopted in which ribs 22 are formed on the outside of the wall panel 5 as shown in FIG. 9 and the ribs 22 and the connecting tool 1 are fixed with screws or the like. Although this method improves watertightness and compensates for the conventional drawbacks, this method also has a problem that the attachment position of the connector 1 is specified and that the attachment dimension accuracy is difficult to obtain.

[0008]

SUMMARY OF THE INVENTION The present invention provides a fixing structure that solves the above-mentioned drawbacks of the prior art, and is a fixing structure for fixing a connector to a flange formed around a wall panel. There is a mortar-shaped hole in the connecting tool and a flange is provided with a play hole, both are fixed with a countersunk screw from the flange side, the periphery of the play hole of the flange is deformed in the mortar-shaped hole, The present invention provides a fixing structure for a wall panel and a connector, characterized in that the head is fitted in the mortar-shaped hole.

[0009]

In the flange of the wall panel, the play hole for the screw is provided at the position where the connector is attached. On the other hand, in the connector, the screw mounting hole is a mortar-shaped hole having a shape and size that allows the head of the dish screw to be housed, and a screw hole is provided in the center thereof. This screw hole is about 0.8 times the screw diameter. Then, by setting both of them and tightening with a countersunk screw from the flange side, the peripheral portion of the flange screw hole is deformed, and the screw head is set within the slot-shaped mounting hole portion of the connecting portion. As a result, the protrusion of the screw head unlike the prior art is completely eliminated, and the mounting dimensional accuracy becomes sufficient. The wall panel is usually made of PVC decorative steel plate or the like, but can be deformed with a dish screw.

Embodiments of the present invention will be further described below with reference to the drawings. 1 is a perspective view of a connector of the present invention, and FIG. 2 is a sectional view taken along line AA of FIG. In the figure, reference numeral 1 denotes a connecting tool used for connecting to a rising portion of a floor panel, and this connecting tool 1 is provided with a fitting portion 2 for fitting to a rising portion of a floor panel and is attached to a flange of a wall panel. A mortar-shaped hole 4 is formed in the flat surface portion 3. The shape of the mortar-shaped hole 4 is a shape sufficient for the head of the dish screw to be fitted therein.

FIG. 3 is a cross-sectional view in which the connector 1 shown in FIGS. 1 and 2 is fixed to the flange 6 of the wall panel 5, both of which are fixed by a countersunk screw 7 from the flange 6 side. The flange 6 is deformed around the play hole 8 of the flange 6 along the inclination of the mortar-shaped hole 4. Therefore, the head 9 of the dish screw 7 sinks by this amount, and when the fixing is completed, the surface of the flange 6 and the head 9 of the dish screw 7 enter the same plane or inside thereof. Therefore, in order to stand the wall panel 5 on the stepped portion 11 formed around the floor panel 10, the fitting portion 2 of the connector 1 is fitted into the rising portion 12 rising up around the stepped portion 11. Both panels 5 and 10 are connected and fixed. At this time, the head 9 of the countersunk screw 7 does not protrude from the surface of the flange 6, and therefore, no gap is formed on the joint surface between the two.

FIG. 4 shows a fixing structure for fixing the wall panel 5 and the ceiling panel 13. A connecting tool 14 for connecting the two is a metal fitting having an L-shaped cross section, and a horizontal portion 15 is shaped like a mortar. Holes 4 are formed. Then, the flange 6 of the wall panel 5 is deformed by the countersunk screw 7 and fitted into the mortar-shaped hole 4. This is similar to the previous example in that the periphery of the play hole 8 of the flange 6 is deformed along the hole 4, and the head 9 of the dish screw 7 is
Does not protrude from the surface of the flange 6. Therefore, there is no gap between the ceiling panel 13 and the flange 6. It should be noted that the flange 16 around the ceiling panel 13 and the upright portion 17 of the connecting tool 14 are also connected and fixed by the screw 23.

FIG. 5 shows an example in which a connector 18 for fixing the wall panels 5 to each other is fixed to the flange 6, and the connector 1
8, the mortar-shaped hole 4 as in the previous example is formed, and both are fixed by the countersunk screw 7 from the flange 6 side. In this case as well, the periphery of the play hole 8 of the flange 6 is deformed and fits inside the hole 4, so that the head 9 of the countersunk screw 7 does not protrude from the surface of the flange 6.

[0014]

The present invention has a structure for fixing the flange of the wall panel and the connecting tool so that the head of the screw used for fixing does not protrude. Therefore, when connecting the flange to another member, they can be connected and fixed to each other without forming a gap therebetween, and the watertightness thereof can be ensured and the connecting and fixing work can be facilitated. .
