Description

LINKING STRUCTURE FOR STUD FOR UNIT HOUSE

Technical Field

[0001] The present invention relates to a coupling structure of a stud which is used in a

prefabricated house and to a coupling structure of a stud for a prefabricated house which

prevents the entry of wind and rain and which can enhance design.

Background

[0002] Conventionally, as a structure for sealing a gap in a prefabricated house, a joint

seal structure in a prefabricated box disclosed in patent literature 1 is proposed. The

seal structure is formed with a sealing member which is inserted from indoor into a joint

in the prefabricated box; and an elastic plate member which is fitted to rails provided in

columns for the joint and which is located on an indoor side with respect to the sealing

member.

[0003] In this seal structure, a double seal structure of the sealing member and the

elastic plate member is adopted, and thus sufficient sealing is provided. Specifically,

the sealing member such as a T-type joiner is inserted from indoor into the joint in the

prefabricated house, then the elastic plate member such as sponge is fitted between the

rails provided on the indoor side of the columns for the joint and thus a double sealed

state is provided.

Summary

Technical Problem

[0005] However, in the seal structure disclosed in patent literature 1, a pair of rails needs to be previously provided on the indoor side of columns adjacent to each other so as to be opposite each other. Hence, in order for the seal structure to be used, two types of columns that include the rails whose orientations are different are needed, and thus the number of types of columns is disadvantageously increased.

[0006] Moreover, the elastic plate member such as sponge which is fitted to the rails is

clearly different in texture from the other materials of the prefabricated house. Hence,

when the seal structure as described above is fitted to the noticeable indoor side, for

example, a sense of discomfort may be provided to a person who sees the seal structure,

and hence, there is still room for improvement in design. Furthermore, the elastic plate

member such as sponge is problematic in water resistance and durability.

[0007] Hence, some embodiments of the present disclosure aim to be made so as to

remove the problems described above. Furthermore, some embodiments of the present

disclosure aim 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 design on an indoor side

while preventing the entry of wind and rain.

Any discussion of documents, acts, materials, devices, articles or the like which

has been included in the present specification is not to be taken as an admission that any

or all of these matters form part of the prior art base or were common general

knowledge in the field relevant to the present disclosure as it existed before the priority

date of each of the appended claims.

Throughout this specification the word "comprise", or variations such as

"comprises" or "comprising", will be understood to imply the inclusion of a stated

element, integer or step, or group of elements, integers or steps, but not the exclusion of

any other element, integer or step, or group of elements, integers or steps.

Summary

[0008] According to the present disclosure there is provided a coupling structure of a

stud 10 for a prefabricated house which is formed such that coupling pieces 21 provided

along coupling side surfaces of wall panels 20 are fixed to a surface of the stud 10 on an

indoor side of the stud installed between left and right sides of a prefabricated house P

including: left and right wall panels, a stud having left and right coupling side surfaces,

coupling pieces, a nut 11 which is fixed to the stud 10; a bolt 12 for screwing into the

nut 11 from an indoor side of the coupling pieces 21 so as to fix the coupling pieces 21

to the stud 10; elastic fin-shaped sealing members 13 fixed along the left and right

coupling side surfaces of the stud for sealing gaps between each coupling side surface

and the respective left and right wall panels 20; and a cover member 14 which is

removably fitted to the coupling pieces 21 from the indoor side of the coupling and

engages with a gap between the respective left and right wall panels at an indoor side of

the wall panels 20 so as to cover the bolt 12 when the bolt is screwed into the fixed nut

11.

[0009] The stud 10 is formed of a C-type channel material, the nut 11 is welded to the

stud at a position such that the bolt 12 can be inserted through the slit 1OA formed by a

longitudinal channel, or opening, formed by the C-section of the stud 10 and screwed

into the nut, wherein each side of the slit 1OA contacts an outdoor side surface of the

respective coupling piece 21 of the left and right wall panels and each coupling piece

having a cut-out through which the bolt 12 is inserted.

[0010] Each sealing member 13 includes: an adhesion portion 13A which is adhered to

the respective coupling side surface of the stud; and two fin-shaped pieces 13B which

are protruded from the adhesion portion 13A toward a side surface of an adjacent wall panel 20, and when the stud 10 isfixed to the coupling pieces 21, the fin-shaped pieces

13B seal the gaps between the stud 10 and the wall panels 20.

[0011] The cover member 14 is configured such that when the cover member is

engaged with the gap between and the left and right wall panels a surface of the cover

member is flush with surfaces of the respective wall panel, and wherein the cover

member 14 is removably attached to the coupling pieces 21 of the wall panels 20 by

magnetism.

[0012] The elastic fin-shaped sealing members 13 which are previously fixed along the

left and right coupling side surfaces of the stud 10 so as to seal the gaps between the

stud 10 and the wall panels 20 is provided, and thus when the wall panels 20 are

installed on both sides of the stud 10, the sealing members 13 simultaneously seal the

gaps. Hence, the sealing members 13 prevents the entry of wind and rain.

[0013] The cover member 14 is provided which engages with the gap of the wall panels

from the indoor side so as to cover the fixed bolt 12 that is fixed to the stud 10, and

thus it is possible to enhance design on the indoor side. Moreover, the wall panel 20

has a symmetrical configuration, and thus it is possible to perform rational fitting.

[0014] The stud 10 is formed of a C-type channel material, the fixed nut 11 is welded to

the position in which the fixed bolt 12 is inserted through the slit 1OA of the stud 10

thereinto and is screwed, the side of the slit is arranged so as to make contact with the

surfaces of the coupling pieces 21 on the outdoor side and the passing-through portions

21A through which the fixed bolt 12 is inserted are formed in the coupling pieces 21 by

being cut out, with the result that the stud 10 and the wall panels 20 are fixed together in

a state where the slit 1OA of the stud 10 overlaps the gap between the coupling pieces

21 of the wall panels 20. Consequently, the coupling structure itself of the stud 10 and the wall panels 20 can interrupt rain and wind, and thus it is possible to reliably prevent the entry of wind and rain.

[0015] The sealing member 13 includes: the adhesion portion 13A which is adhered to

the side surface of the stud 10; and the two fin-shaped pieces 13B which are protruded

from the adhesion portion 13A toward the coupling side surface of the adjacent wall

panel 20, and when the stud 10 is fixed to the coupling pieces 21, the fin-shaped pieces

13B seal the gaps between the stud 10 and the wall panels 20, with the result that the

sealing members 13 is durable so as to be used repeatedly together with the stud 10.

[0016] The cover member 14 has a thickness which has the same height as the inner

surfaces of skeletons of the wall panels 20, and the cover member 14 is removably

attached to the coupling pieces 21 of the wall panels 20 by magnetism, with the result

that it is possible to achieve excellent appearance design of the prefabricated house P on

the indoor side. Moreover, since the cover member 14 is attached to the coupling

pieces 21 by magnetism, the cover member 14 is easily fitted thereto and can be

repeatedly used any number of times.

[0017] As described above, according to the present disclosure, the present disclosure

aim to provide some embodiments in which durability is high so as to achieve repeated

use and in which it is also possible to enhance appearance design while preventing the

entry of wind and rain.

Description of Embodiments

[0019] An embodiment of the present disclosure will be described below. 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).

[0020] 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).

[0021] 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 1OA of the stud 10 thereinto and are screwed.

[0022] 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 1OA in the stud 10 (see Fig. 3). In the

illustrated coupling pieces 21, tip end portions are bent toward the slit 1OA 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).

[0023] 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.

[0024] 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.

[0025] 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).

[0026] 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).

[0027] 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).

[0028] 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

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.

[0029] The configuration of the prefabricated house P in the present disclosure is not

limited to the illustrated example, and the configurations and the shapes of the stud 10,

the wall panel 20, the sealing member13, 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 disclosure.
