Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a joining structure of studs used for partition wall surfaces.

[Conventional technology]

Conventionally, in this type of stud joining structure, both studs have been joined by screwing or the like using an L-shaped metal fitting at the joining portion.

[Problems to be solved by the device]

However, in the above structure, there is a problem that both studs are misaligned during joining and workability is deteriorated. In addition, due to the cross-sectional shape of the stud, a gap may be formed at the joint, and the appearance may be deteriorated.

Therefore, an object of the present invention is to provide a stud joining structure that prevents displacement of both studs in the joining portion and does not cause a gap in the joining portion.

[Means for Solving the Problems]

The stud joining structure of the present invention has a pair of substantially square tubular studs having chamfered tapered surfaces at the corners and provided with facing recesses, and both edges are housed in the facing recesses. A stud cover, a pair of stud caps each having a locating piece whose bottom surface is inclined so as to correspond to the tapered surface, and a supporting piece erected from the locating piece are provided. The studs are joined to one side of the stud, and a pair of stud cap positioning pieces are interposed between one end surface of one stud and the tapered surface of the other stud, and the support piece is placed between the stud cover and one stud. Both sides of the stud cover are housed in the facing groove while being sandwiched between them.

[Action]

According to the configuration of this invention, one stud is sandwiched by the support pieces of the pair of stud caps, and the positioning piece is straddled over the opposing tapered surfaces of the other stud.
One stud can be positioned in the front-back direction. Therefore, it is possible to prevent positional deviation between the studs and improve workability. Further, there is an advantage that the stud cap closes the gap of the joint portion caused by the sectional shape of the stud. Further, the stud cap may be attached to the end surface of one of the studs before joining the studs, or may be attached after joining the studs.

〔Example〕

A stud joining structure according to an embodiment of the present invention will be described with reference to FIGS.

1a, 1b, 1c are studs, 2 is a stud cover, and 3 is a stud cap. The studs 1 ... Are arranged between the panels 12, 12 and are formed in a substantially rectangular tube shape. Specifically, the tapered surface 5 chamfered at the corner of the stud 1 ...
The umbrella body 15 having the above is formed, and the accommodation groove 6 which faces the inside of the umbrella body 15 is provided. The stud cover 2 is provided with a ridge 7 whose both side edges are bent and are stored in the groove 6. The stud cap 3 has a positioning piece 8 whose bottom surface is inclined so as to correspond to the tapered surface 5, and a support piece 9 which is erected from the positioning piece 8 and has a substantially U-shaped cross section. A protrusion may be provided on the web of the support piece 9 so as to be aligned with the flange.

Next, the horizontal stud 1b is attached to one side of the vertical stud 1a.
The assembling procedure at the joint portion A for joining the one end faces of will be described. That is, as shown in FIG. 2, a pair of stud caps are provided on opposite side surfaces of the end of the horizontal stud 1b.
Protrusions 7 of the stud cover 2 are provided by disposing support pieces 9 and 9 of 3 and 3.
Fit in the groove 6. By this, a pair of support pieces
The ends of the stud 1b are clamped by 9,9. Then, the vertical stud 1a and the horizontal stud 1b are tapped to the L-shaped metal fitting 10 with the positioning pieces 8 and 8 positioned on the taper surfaces 5 and 5 of the vertical stud 1a and positioned in the front-rear direction. Fasten with 11 and join both studs 1a, 1b. In this case, even after both the studs 1a and 1b are joined by the L-shaped metal fitting 10, the stud cap 3 can be attached by the same method.

Further, an assembling procedure at the joint B for joining the vertical lower end surface of the stud 1c to the side surface of the horizontal stud 1b facing upward will be described. That is, similarly to the joint portion A, the support pieces 9 and 9 of the pair of stud caps 3 and 3 are arranged on the opposite side surfaces of the lower end portion of the vertical stud 1c, and the ridge 7 of the stud cover 2 is accommodated in the groove 6. Fit in. Then, the positioning piece 8,
The vertical stud 1c is positioned in the front-rear direction by straddling 8 on the tapered surfaces 5, 5 of the horizontal stud 1b.
Further, since the panel 12 is positioned in the left-right direction, it is not necessary to use the L-shaped metal fitting 10.

The panels 12 are arranged in the space defined by the studs 1 as described above. That is, as shown in FIG.
The panel 12 is positioned by sandwiching the edges of the panel 12 between the umbrella bodies 15, 15. The stud cover 2 is also attached to the exposed side surface of each stud 1. 16 is a Kasaki, and 17 is a Kasaki adapter.

4 and 5 show another embodiment in which a stud cap 3'having a different shape is used. The stud cap 3'has support pieces 9'protrudingly provided at both ends thereof, and the support pieces 9'are accommodated in the opposing receiving grooves 6. Other structural effects are similar to those of the above-described embodiment.

[Effect of device]

According to the stud joining structure of the present invention, one stud is sandwiched between the support pieces of the pair of stud caps and the positioning piece is straddled over the opposite tapered surfaces of the other stud. Directional positioning is possible. Therefore, it is possible to prevent positional deviation between the studs and improve workability. Further, the stud cap closes the gap of the joint portion caused by the cross-sectional shape of the stud, so that the appearance can be improved. Further, the stud cap may be attached to the end surface of one of the studs before joining the studs, or may be attached even after joining the studs, which can be adapted according to the situation at the site.
