Description

[Detailed description of the invention] The present invention relates to a sanderch panel used for partitioning a room, for example, or constructing a unit bath or clean room wall. Regarding the chip panel.

Techniques for improving the sealing performance of this type of sandwich panel during the manufacturing process have been proposed in Japanese Utility Model Application No. 55-86815 and Japanese Patent Application Laid-open No. 55-107434. This proposal involves inserting a rod-shaped sealing material made of soft alloy resin between the front and back plates, bonding them together, and compressing and expanding the sealing material using the foaming pressure when the resin is foamed. An attempt was made to improve sealing performance by crimping the front and back plates to the peripheral edges of the front and back plates. However, in this proposal, because the sealant is sandwiched between the front and back plates,
The peripheral frame must be attached to the outer surface of the peripheral edge of the front and back plates, and this creates a step between the peripheral frame and the front and back plates, resulting in poor appearance and especially when used as a wall material for a unit bath. However, there is a problem in that water droplets and dust accumulate in the stepped portion, causing rust.

The main purpose of the present invention is to solve the above-mentioned difficulties, and one embodiment of the present invention will be explained below based on the drawings. As shown in FIG. 3, a sealing peripheral frame 5 or 6 is sandwiched between the peripheral edges of the inner and outer front and back plates 3, 4, and the front and back plates 3,
The sealing frame 5 of the panel 1 shown in FIGS. External wall portion 5a and a pair of side wall portions 5b, 5b
It has a main body 5c with a substantially U-shaped cross section consisting of the outer surfaces of the side walls 5b, 5b of the main body 5c, that is, the front and back plates 3,
A concave portion 8 is provided on the surface facing the panel 4, and the sealing peripheral frame 6 of the panel 2 shown in FIGS. A pair of side wall portions 6c connecting the wall portions 6a and 6b,
The main body 6d has a substantially hollow rectangular main body 6d consisting of a substantially hollow rectangular main body 6d, and recessed portions 9 are provided on the outer surfaces of the side wall portions 6c, 6c of the main body 6d, that is, on the surfaces facing the front and back plates 3 and 4, and the above-mentioned inner An umbrella-shaped retaining rib 10 projects from the center of the face wall portion 6b. and each panel 1
or 2, the recesses 8 and 9 of each sealing peripheral frame 5 or 6 are filled with the sealing material 11, or a tape-shaped sealing material is pasted, and the side walls 5b and 6c are Adhesive 12 is applied to the outer surface of the front and back plates 3 and 4 and the sealing frames 5 and 6 are sandwiched between the front and back plates 3 and 4. 3a, 4a are attached and glued to the outer wall portions 5a, 6a, and a resin core material 7 such as urethane is inserted through a filling port (not shown) that has been penetrated in the appropriate position in the sealing peripheral frames 5, 6 in advance. Front and back plates 3, 4
Inject in between and foam filling. At this time, in the panel 2, as the resin core material 7 is filled with foam, an umbrella-shaped retaining rib 10 is embedded in the resin core material 7, so that the rib 10 allows the sealing peripheral frame 6 to be connected to the resin core material 7. This means that the core material 7 is firmly connected to the core material 7. Note that the filling port is closed with a suitable plug after the resin core material 7 is foamed and filled. Panel 1 thus produced
or 2 must have a joint structure so that the panels can be connected to each other in order to constitute a partition wall or a unit bath wall. Therefore, in panel 1 shown in Fig. 1, both vertical sides of the panel A joint frame portion 13 extends from the outer wall portion 5a of the peripheral frame body 5c, and approximately L-shaped ribs 14, 14 are protruded from the side outer surface of the joint frame portion 13, so that both ribs 1
A connecting fitting fitting groove 15 is formed between 4 and 14, and in the panel 2 shown in FIG.
A required number of grooves 6 are formed on the upper and lower sides, and gasket fitting grooves 17 are recessed. Then, as shown in FIG. 3, the connection fitting 18 is inserted into the connection fitting fitting groove 15 of the panel 1, and the packing 19 is fitted into the packing fitting groove 17 of the other panel 2. The hook portion 20 is engaged with the hook engagement hole 16 on the panel 2 side to draw both panels 1 and 2 together, and the sealing peripheral frame 5 of the panels 1 and 2 is
The gasket 19 is compressed between the panels 6 and 6 to seal, and the panels 1 and 2 are connected to each other. In addition, the sealing panel frames 5 and 6 on the upper and lower sides of each panel 1 and 2
does not require connection between panels,
It is sufficient to provide only the above-mentioned main body structures 5c and 6d on the upper and lower sides.

In addition, in FIG. 3, another peripheral frame 21 is inserted and inserted vertically into the middle part of the panel 1, but this is because the entire length of the panel 1 is relatively long, and the front and back panels are made of a single plate. 3 and 4, respectively, so the two left and right front plates 3 and 3 and the back plates 4 and 4 are connected by a peripheral frame 21 at the middle part of the panel 1. Therefore, this peripheral frame 21 has a shape in which side wall portions 21b and 21c extend outwardly from both sides of the partition wall portion 21a, and both side wall portions 21b and 21c
A groove 22 for engaging the bent flange portions 3a, 4a of the front and back plates 3, 4 is formed between them. Reference numeral 23 denotes a recessed portion provided on the outer surface of each side wall portion 21b, 21c.

As described above, the present invention provides a sandwich panel formed by foam-filling a resin core material between the inner and outer front and back plates. The edge flange portion is attached to the outer surface of the sealing frame, and the peripheral edges of the front and back plates and the sealing frame are bonded with adhesive, so that only the front and back plates are exposed on the inner and outer surfaces. ,
Since there are no steps, the appearance is good, and especially when used as a wall material for a unit bath, it is possible to prevent water droplets and dust from accumulating on the wall surface, which can cause rust and unsanitary conditions.

In addition, a recess is provided on the surface of the sealing peripheral frame that faces the front and back plates, and the recess is filled with or affixed with a sealing material, so that the sealing peripheral frame can be sandwiched between the sealing frames as described above. By simply polymerizing and adhering the front and back plates to the upper and lower surfaces of the front and back plates, the filled resin will not leak from between the front and back plates and the peripheral frame, and in particular, by bending the edges of the front and back plates into an L shape. Since the flange portion formed by the above method is attached to the outer peripheral surface of the sealing peripheral frame and the peripheral frame is supported by the flange portion, the peripheral frame does not protrude from the front and back plates due to the foaming pressure during resin foam filling.

Furthermore, in terms of the manufacturing process, between the front and back plates, an L-shaped flange part is bent in advance at the edge of the peripheral part,
The frame can be assembled simply by sandwiching a sealing frame filled with or affixed with a sealing material into the concave part, and the manufacturing process is extremely easy as all that is required is to foam and fill the hollow part of the frame with resin. It is.
