Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a joint structure between a wall panel and a ceiling panel constituting a prefabricated room space such as a bathroom unit, a washroom unit, a shower room unit, etc.

[Prior art and its problems] When providing room spaces such as bathrooms, washrooms, shower rooms, etc. in residential buildings, prefabricated units are sometimes used in order to shorten the construction period. The outline of these assembly methods will be explained using the bathroom unit shown in FIG. 5 as an example. First, the floor panel 2 and bathtub 3 are installed on the foundation structure 1, and the wall panel 4 is erected on the periphery of the floor panel 2. The wall panel 4 is constructed by attaching a decorative panel 4b to a frame 4a made of square pipes or the like. Note that the surface of the decorative panel 4b may be finished with a tile surface, if necessary. Next, the ceiling panel 5 is placed on the upper end surface of the frame 4a of the wall panel 4, and as shown in FIG.
A suitable number of screw holes 5c, 4c are drilled in the side edges of the wall panel 4 and the frame 4a of the wall panel 4 using a drill or the like, and fixing screws 6 are screwed into the frame 4a to fix the ceiling panel 5. However, as the wall panel 4 is erected close to the building frame A as shown in FIG. This must be done in a very narrow space between A and the wall panel 4. Therefore, complicated installation work such as drilling screw holes and fixing screws is very inefficient and has poor workability. In addition, a relatively large number of screw holes are required to attach the ceiling panel 5, but since metal is often used for the frame 4a of the ceiling panel 5 and wall panel 4, the drilling work is very time-consuming. It was hot.

[Purpose of the invention] In order to solve the above-mentioned problems, the purpose of the invention is to provide a joint structure that can simply, quickly and firmly join a wall panel and a ceiling panel using an engagement tool without using fixing screws. .

[Structure of the invention] The gist of the invention is to provide a structure in which a wall panel in which a joining piece is installed horizontally on the upper side of the back side and a ceiling panel placed on the upper end surface of the wall panel are joined by an engaging tool. The fitting includes a connecting part with a flange formed on the outside and an elastic push-in part formed in a bulge at the lower end of the connection part, and the connecting piece of the wall panel has a diameter larger than the outer diameter of the elastic push-in part of the engagement tool. A narrow slit is formed continuously or intermittently in the longitudinal direction, and the ceiling panel is provided with an insertion hole having an inner diameter that allows the elastic push-in part of the engagement tool to be inserted in the joint part, and the ceiling panel The engagement tool has an elastic pushing part press-fitted from the insertion hole into the slit of the joint piece of the wall panel, and the collar part pinches the opening periphery of the insertion hole, and the elastic pushing part presses the inner opening edge of the slit. This is because the pressure was applied.

With this configuration, the engagement tool uses the flange to pinch the opening periphery of the ceiling panel insertion hole, and the elastic push-in part to pinch the inner opening edge of the slit in the joint piece, making drilling work unnecessary. To easily, quickly and firmly join a ceiling panel and a wall panel without having to do so.

[Description of Embodiments] The present invention will be described below based on embodiments shown in the drawings. FIGS. 1 and 2 show a first embodiment of a joint structure for a wall panel and a ceiling panel according to the present invention. The engagement tool 7 includes a connecting part 7b having a flange 7a formed on the outside, and an elastic push-in part 7c in the shape of a hollow abacus bead formed in a bulge at the lower end of the connecting part 7b. and elastic push-in part 7c
An appropriate number of vertical slits 7d are cut in the. In the wall panel 8, a frame 9 is arranged on the back side of the decorative panel 8a, and tiles 10, 10, . . . are attached to the front side of the decorative panel 8a. A joint piece 9b made of the upper wall of the hollow frame 9 horizontally installed above the back side of the wall panel 8 has a slit 9 having a width narrower than the outer diameter of the elastic push-in portion 7c of the engagement tool 7.
a are provided continuously or intermittently in the longitudinal direction of the frame. The ceiling panel 11 is the wall panel 8
A joint portion 11b at the side edge is placed on the joint piece 9b, and an insertion hole 11a having an inner diameter into which the elastic push-in portion 7c of the engagement tool 7 can be inserted is provided along the side edge as appropriate. It is perforated in the pitch. Then, the ceiling panel 11 is joined and fixed to the wall panel 8 using an appropriate number of engagement tools 7 as follows. That is, by press-fitting the elastic push-in part 7c of the engagement tool 7 from the insertion hole 11a of the ceiling panel 11 into the slit 9a of the joint piece 9b, the collar part 7a of the engagement tool 7 opens the insertion hole 11a of the ceiling panel 11. While squeezing the peripheral edge of the upper opening, the shoulder of the elastic push-in part 7c presses the lower opening edge of the slit 9a of the joining piece 9b upward,
A ceiling panel 11 is firmly joined to a wall panel 8.

FIG. 3 shows a second embodiment of the present invention, and the difference from the first embodiment shown in FIGS. 1 and 2 is that the wall panel 16 is joined by bending decorative steel plates. Piece 16b and decorative panel portion 16c
is integrally formed, and the joint piece 16b has a slit 16a having a width narrower than the outer diameter of the elastic push-in part 7c of the engagement tool 7.
are provided continuously or intermittently in the longitudinal direction of the joint piece, and insertion holes 17a having an inner diameter into which the elastic push-in portion 7c of the engagement tool 7 can be inserted are bored at appropriate pitches in the bent joint piece 17b of the ceiling panel 17. The elastic push-in portion 7c of the engagement tool 7 is press-fitted into the insertion hole 17a and the slit 16a from the lateral direction.

FIG. 4 shows a third embodiment of the present invention, and the difference from the first embodiment shown in FIGS. 1 and 2 is that A slit 19a having a width narrower than the outer diameter of the elastic push-in portion 7c of the engagement tool 7 is provided continuously or intermittently in the longitudinal direction of the frame in the joint piece 19b made of the lower wall of the hollow frame 19, and the slit 19a is provided in the joint piece 19b consisting of the lower wall of the hollow frame 19, and the slit 19a is continuously or intermittently provided in the longitudinal direction of the frame.
An insertion hole 20a having an inner diameter into which the elastic push-in part 7c of the engagement tool 7 can be inserted is formed at an appropriate pitch in the bent joint piece 20b, and the engagement tool 7 is inserted into the insertion hole 20a from below.
and is press-fitted into the slit 19a.

[Function] As shown in FIGS. 2 to 4, the joining structure of the wall panel and the ceiling panel according to the present invention is such that the flange 7a of the engagement tool 7 connects the insertion holes 11a, 17a of the ceiling panels 11, 17, 20. , 20a, and the elastic push-in portion 7c connects the joining pieces 9b, 16b,
Since the inner opening edges of the slits 9a, 16a, 19a of 19b are squeezed, the ceiling panels 11, 1
7, 20 and wall panels 8, 16, 18 are firmly joined.

[Effects of the invention] As detailed above, the joining structure of the wall panel and ceiling panel according to the invention eliminates the need for drilling work using a drill, etc., which was required in the past, so the joining work is extremely simple. This reduces the time required for joining work. Furthermore, since the joining piece of the wall panel is provided with slits continuously or intermittently in the longitudinal direction, there is an advantage that the fixing position of the engaging tool can be changed as appropriate to suit the construction site.
