DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for connecting panels.

[0002]

2. Description of the Related Art A wall panel formed by bending a steel sheet such as a vinyl chloride coated steel sheet has been known, but this wall panel is widely used because it is easy to manufacture and inexpensive. When connecting the wall panels formed by bending this steel plate, as shown in FIG.
The bent pieces of the steel plate at the side ends of A are connected to each other by bolts 50 and nuts 51. However, for example, when assembling a bathroom panel by assembling a wall panel in a building body, the connection by the bolts 50 and the nuts 51 must be performed outside the bathroom unit to be formed, and the workability is extremely poor. There is. In addition, if a wall panel formed by bending a steel plate such as a vinyl chloride coated steel plate is provided with an opening for a window or an opening for fitting a storage box, lighting equipment, a ventilation fan, or the like, the strength becomes weak. Cannot be provided.

[0003] Accordingly, the opening is provided so that there is no problem in strength, and the strength is secured by a frame as shown in FIG. 18 so that the connecting operation can be performed from the inside of the bathroom unit to be formed. A frame panel 3 configured as described above has been proposed. Since the strength of the frame panel 3 is ensured by the frame, there is no problem even if the opening is provided. Further, the frame panel 3 has a U-shaped vertical frame portion 4 with a lip in cross section which is open outward at a side end. Then, a connection tool 52 having a substantially H-shaped cross section with both sides being bulged portions is prepared, and both bulged portions are placed in the U-shaped vertical frame portion 4 with a lip cross-section of the adjacent frame panel 3. The two frame panels 3 are connected to each other by a connection operation from the inside of the bathroom unit formed. However, the frame panel 3 provided with the vertical frame portion 4 has a problem that manufacturing is troublesome and cost is high.

[0004] Conventionally, only a wall panel 1A formed by bending a steel plate such as a vinyl chloride coated steel plate is connected to each other to form a wall of a bathroom unit or to form a frame panel 3a. Only the wall panel 1A and the frame panel 3 formed by bending a steel plate were not connected.

[0005]

Smaller and larger than the small-diameter hole, the large-diameter hole of the Daruma hole is inserted into the large-diameter projection of the engaging projection, and the engaging projection and the engaging hole are not relatively displaced. The radial projection can be easily engaged with the small-diameter hole, and the coupling structure is simple and quick coupling can be performed.

According to a fourth aspect of the present invention, in addition to the effects of the second aspect of the invention, in addition to the above-mentioned effects, an engaging hole comprising a plurality of vertical holes provided at the side end of the ordinary wall panel, An engagement hole comprising a round hole provided at a side end of the lower small wall panel,
An engagement hole formed of a round hole provided at a side end of the upper small wall panel is formed such that the large diameter hole of the round hole is located on the upper side and the small diameter hole is located on the lower side. An engagement hole formed of a round hole provided on the plate is formed so that the large diameter hole is located on the lower side and the small diameter hole is located on the upper side. The lower engaging hole of the mating hole is formed such that the large-diameter hole is located on the lower side and the small-diameter hole is located on the upper side, and the upper engaging hole has the large-diameter hole located on the upper side and Since the small diameter hole is formed so as to be located on the lower side, the basic wall panel and the lower small wall panel can be connected by driving the connecting member from above, and the connecting member and the frame panel are driven by driving the connecting plate from above. Can be connected, and the connecting plate is driven into the lower small wall panel and the frame panel by driving in from above. The upper small wall panel, the connecting plate and the basic wall panel can be connected by driving the joiner from above, and thus the connection structure can be easily connected only by the driving operation from above. It is for simplicity.

According to the fifth aspect of the present invention, in addition to the effect of the first or second aspect of the present invention, the engaging hole has a large-diameter hole at the central portion and the upper and lower portions of the large-diameter hole. The engaging projection is composed of a small-diameter neck portion of the protruding base and a large-diameter projection portion whose front portion is larger than the neck portion, and the neck portion is smaller than the small-diameter hole. Because the small, large-diameter protrusion is smaller than the large-diameter hole and larger than the small-diameter hole,
The large-diameter protrusion is fitted into the large-diameter hole, and the engagement protrusion and the engagement hole are relatively shifted vertically, so that the large-diameter protrusion is securely engaged with the small-diameter hole above or below the engagement hole. And the engagement holes are turned upside down without any problem.

According to the sixth aspect of the present invention, in addition to the effects of the first or second aspect of the present invention, a window is formed in the frame panel. Since the panel is a panel, there is no problem in strength, and the frame panel provided with the window can be connected to a wall panel formed by bending a steel plate with a simple configuration by engagement.
