LINKING STRUCTURE FOR STUD FOR UNIT HOUSE

Abstract

An object is to provide a coupling structure of a stud for a prefabricated house which is durable so as to be used repeatedly and which can enhance appearance design.

A fixed nut 11 is previously fixed to a stud 10. A fixed bolt 12 is provided which screws to the fixed nut 11 so as to fix coupling pieces 21 to the stud 10. Sealing members 13 are previously provided along the left and right coupling side surfaces of the stud 10. The sealing members 13 are used to seal gaps between the stud 10 and wall panels 20. A cover member 14 is provided which engages with the gap of the wall panels 20 on an indoor side.

Claims

A coupling structure of a stud for a prefabricated house which is formed such that coupling pieces provided along coupling side surfaces of wall panels are fixed to a surface of the stud on an indoor side installed between the wall panels on left and right sides in the prefabricated house, the coupling structure comprising: a fixed nut which is previously fixed to the stud; a fixed bolt which screws to the fixed nut from the indoor side of the coupling pieces so as to fix the coupling pieces to the stud; elastic fin-shaped sealing members which are previously fixed along left and right coupling side surfaces of the stud so as to seal gaps between the stud and the wall panels; and a cover member which is removably fitted to the coupling pieces from the indoor side and engages with a gap of the wall panels on the indoor side so as to cover the fixed bolt that is fixed to the stud.

2. The coupling structure of the stud for the prefabricated house according to claim 1, wherein the stud is formed of a C-type channel material, the fixed nut is welded to a position in which the fixed bolt is inserted through a slit of the stud thereinto and is screwed, a side of the slit is arranged so as to make contact with surfaces of the coupling pieces on an outdoor side and passing-through portions through which the fixed bolt is inserted are formed in the coupling pieces by being cut out.

3. The coupling structure of the stud for the prefabricated house according to claim 1, wherein the sealing member includes: an adhesion portion which is adhered to the side surface of the stud; and two rows of crimp contact pieces which are protruded from the adhesion portion toward the coupling side surface of the adjacent wall panel, and when the stud is fixed to the coupling pieces, the crimp contact pieces seal the gaps between the stud and the wall panels.

4. The coupling structure of the stud for the prefabricated house according to claim 1, wherein the cover member has a thickness which has the same height as inner surfaces of skeletons of the wall panels, and the cover member is removably attached to the coupling pieces of the wall panels by magnetism.

DESCRIPTION OF EMBODIMENTS

[0023] An embodiment of the present invention will be described below. The present invention is a coupling structure of a stud 10 which couples together wall panels 20 in a prefabricated house P that is produced in a factory and is assembled locally (see FIG. 1).

[0024] In other words, the stud 10 is installed between the wall panels 20 on left and right sides (see FIG. 2). On the side surfaces on the left and right sides of the wall panel 20, coupling pieces 21 are provided along the coupling side surfaces of the stud 10. The coupling pieces 21 of the wall panels 20 are fixed to the surface of the stud 10 on the indoor side (see FIG. 3).

[0025] The illustrated stud 10 is formed of a C-type channel material. Fixed nuts 11 are provided therewithin, and with fixed bolts 12 for screwing to the fixed nuts 11 from the indoor side of the coupling pieces 21, the coupling pieces 21 are fixed to the stud 10 (see FIG. 4). Hence, the fixed nuts 11 are welded to positions in which the fixed bolts 12 are inserted through the slit 10A of the stud 10 thereinto and are screwed.

[0026] When the surface of the stud 10 on the indoor side and the surfaces of the coupling pieces 21 on an outdoor side are brought into contact with each other, a gap between the coupling pieces 21 overlaps the slit 10A in the stud 10 (see FIG. 3). In the illustrated coupling pieces 21, tip end portions are bent toward the slit 10A so as to form insertion portions 21B, and when the stud 10 and the coupling pieces 21 are fixed together, the insertion portions 21B are inserted through the slit 10A into the stud 10 (see FIG. 4).

[0027] Furthermore, on the left and right coupling side surfaces of the stud 10, elastic fin-shaped sealing members 13 are provided which makes contact with the coupling side surfaces of the wall panels 20 (see FIG. 5). When the wall panels 20 are installed on both sides of the stud 10, gaps between the stud 10 and the wall panels 20 are sealed with the sealing members 13 (see FIG. 4). Consequently, it is possible to prevent the entry of wind and rain through the gaps of the wall panels 20.

[0028] The illustrated sealing member 13 includes an adhesion portion 13A and a pair of crimp contact pieces 13B (see FIG. 3). Specifically, the adhesion portion 13A is a band-shaped part which is adhered to the side surface of the stud 10, and the crimp contact pieces 13B are integrally formed so as to be protruded from the adhesion portion 13A.

[0029] The crimp contact pieces 13B are formed in the shape of two rows of fins which are protruded from the adhesion portion 13A toward the coupling side surface of the adjacent wall panel 20, and the gap between the stud 10 and the wall panel 20 are double-sealed (see FIG. 4).

[0030] After the coupling pieces 21 of the wall panels 20 are fixed to the stud 10, a cover member 14 is fitted to the coupling pieces 21 from the indoor side (see FIG. 3). The cover member 14 is a strip-shaped member which engages with a gap of the wall panels 20 on the indoor side, and the cover member 14 covers the fixed bolt 12 which is fixed to the stud 10 (see FIG. 4).

[0031] Since the cover member 14 has a thickness which has the same height as the inner surfaces of skeletons of the wall panels 20, when the cover member 14 engages with the gap of the wall panels 20, the surfaces of the wall panels 20 are flush with the surface of the cover member 14 (see FIG. 4).

[0032] Furthermore, a permanent magnet is provided in the cover member 14, and thus the cover member 14 is removably attached to the coupling pieces 21 of the wall panels 20 by magnetism. Hence, the cover member 14 can easily be fitted by performing only an operation of bringing the cover member 14 close to the coupling pieces 21 from the indoor side.

[0033] The configuration of the prefabricated house P in the present invention is not limited to the illustrated example, and the configurations and the shapes of the stud 10, the wall panel 20, the sealing member 13, the cover member 14 and the like can be arbitrarily changed. The design can freely be changed without departing from the spirit of the present invention.
