Description

[Detailed explanation of the idea] The present invention relates to wall structures in wooden buildings.

In conventional wooden buildings, for example, the braces and rims or studs each occupied their own planar space, so they were surrounded by two foundations, horizontal members such as girders, and two pillars such as through columns and studs. It was impossible to attach shielding boards for insulation, soundproofing, etc. to the entire surface of a large rectangular plot.

In addition, although it is possible to fill small sections separated by studs, girders, bracing, etc. with insulation materials, heat and sound shielding boards generally allow heat and sound to leak from the surrounding gaps. Therefore, the smaller the area of a single shielding plate, the lower the actual shielding effect, and therefore it is not preferable to make the partition smaller.

In this case, there is a method of sealing the peripheral gap with a sealing material, but it is time-consuming and the construction cost is enormous.

Particularly in cold regions or in winter, when there is a large temperature difference between the outside air and the room temperature, even a small gap will cause cold air and warm air to come into contact and cause condensation or ice, so the reduction in the shielding effect is significant.

Generally, when aiming for heat insulation or soundproofing, it is known that a wall with a two- or three-layer structure separated by space is much more effective than a single-layer structure made of a single member.

However, when considering the maintenance of voids in a multi-layered structure in the wall structure of a wooden building, it is difficult to install a multi-layered shielding plate in a space with a column thickness of, for example, only 1QQmm. It was thought that it was impossible to obtain walls of a satisfactory thermal or soundproof structure in a wooden building.

The purpose of this invention is to create a thin and wide interior of a wooden structure surrounded by horizontal members such as two pillars, two foundations, girders, and girders, for example, an area of 2 m x 1 m and a thickness of 10 cm. To provide a wall structure in which a large heat insulating panel or a sound insulating panel covering the entire wall surface can be provided in a space, in addition to the outer wall and the indoor interior panel.

Hereinafter, the present invention will be explained based on drawings of embodiments.

Figure 1 is an overall front view of the wall framework structure according to the present invention, Figure 2
3 is a partial perspective view of section A in FIG. 1, FIG. 3 is a partial perspective view of section B in FIG. 1, and FIG. 3 is a partial perspective view of section C in FIG. 1.

The overall construction is, for example, by standing two pillars 2 and 3 upright on a foundation 1, and building an eaves 4 on top of them, connecting the pillars 2 and 3 with 5 through the center, and bracing 6. , 7 and furring receivers 8, 9
, 10.11 are installed.

Each inner surface 1a of the two columns 2, 3 and the two horizontal members 1, 4
, 2 a , 3 a , and 4 a each have a central groove (for example, indicated by reference numerals 1 b and 3 b in FIGS. 2 and 3).

In addition, there are small grooves for fitting interior panels, etc. on the surfaces of the inner surfaces 1a, 2a, 3a, 4a on the indoor side of the central grooves 1b, 3b (for example, Figs. 2 and 3). 1c and 3c) are shown in the figure, respectively.

Nuki 5, braces 6, 7 and body edge receivers 8, 9, 10.11
The thickness, that is, the thickness in the direction perpendicular to the plane of the paper in FIG. 8,9,10.1
1 are all inner surfaces 1a, 2a of the above members 1, 2, 3.4
, 3a, 4a within the space surrounded by the central grooves.

To explain such a structure in more detail, the pillars 2, 3 and the slot 5 are joined using, for example, a joining fitting 12, a nut 13, and a pin 14 shown in FIG.

The joining fitting 12 has a flat plate-like penetration part 15 and a handle part 16, a screw 17 is carved in the tip of the handle part 16, and a pin hole 18 is bored in a predetermined position of the penetration part 15. .

The width b of this penetration portion is approximately equal to the thickness of the cutout 5.

Cut grooves are carved along the central plane of both ends of the slot 5 and the penetration portion 15 is inserted, a pin hole is drilled at a position corresponding to the pin hole 18 and the pin 14 is inserted therethrough, and the slot 5 and the metal fitting 12 are inserted. to be fixed.

Further, a through hole through which the handle 16 passes is bored in the center of the pillars 2 and 3, a washer is applied, and the metal fitting 12 and the pillars 2 and 3 are fixed with nuts 13.

The braces 6 and 7 are held at both ends by central grooves and slots 5 formed in the columns 2 and 3 and the horizontal members 1 and 4.

As shown in FIGS. 2 and 4, the braces 6 and 7 have grooves 6 a and 6 on the side faces facing the columns 2 and 3.
b or 7a, 7b are engraved, and the body edge receivers 8, 9,
10. The protrusion provided at one end of 11 fits into the concave groove 6b, 6b or 7b, 7b, and the other end of the furring support is connected to the pillar 2,
It fits into the central concave groove of No.3.

In the above structure, the members that make up the outer periphery of the wall, such as the foundation 1, pillars 2 and 3, and the eaves 4, are considered to be the outer periphery of the wall.
, braces 6, frame supports 8, 9, 10.11, etc., which make up the interior of the wall, can be generally expressed as internal structures or members, and can be explained using the cross-sectional model shown in Figure 6. .

That is, as schematically shown in FIG. 6, a plane P1 formed by the outdoor side surface 21a of the outer peripheral structure or member 21 of the wall such as the foundation, pillar, girder, etc. There is no internal structural material between the plane P2 formed by the outdoor side surface 22a of the internal structural member 22 of the wall, forming a complete space.

Similarly, a complete space is formed between the plane P3 formed by the indoor side surface 2lb of the outer peripheral structure or member 21 and the plane P4 formed by the indoor side surface 22b of the internal structure member 22. It's intimidating.

Here, a complete space refers to a space in which there are no members such as braces, rims, rim holders, or slots within a predetermined length, width, and thickness.

In this way, since a complete space is formed on both sides of the wall internal structure or member, the insulation plate 1 made of heat insulating material, soundproofing material, etc. can be easily attached.

FIG. 7 shows a sectional view of an embodiment of the present invention.

A first shielding plate 23 is attached to the outdoor side surface 22a of the internal structure member 22, which is attached with reference to the central groove 21C of the outer peripheral structure or member 21, and a second shielding plate 24 is attached to the indoor side surface 22b. Further, an outer wall panel 25 is attached to the outdoor side surface 21a of the outer circumferential structural member 21, and an exterior covering 26 such as mortar is applied to the outside thereof.

An interior panel 27 is attached to the small groove 21 d of the outer peripheral structure or member 21 .

Therefore, between the outer wall panel 25 and the first shielding plate 23, the first
a space layer 28 , a second space layer 29 between the first and second shielding plates 23 , 24 , a second shielding plate 24 and the interior panel 27
A third spatial layer 30 is formed in between.

As the first and second shielding plates 23,24, for example,
Heat and sound insulation materials such as wood fiber panels, foamed plastic panels, and rock wool panels are used.

Furthermore, one or more of the space layers 28, 29, and 30 may be filled with a cotton-like material such as glass cotton.

Further, either one or both of the first and second shielding plates 23, 24 may be made of a noncombustible material such as rock wool.

FIG. 8 shows a cross-sectional view of another embodiment of the present invention in which both sides of a wall outer peripheral structure or member 21 such as a column are exposed.

In the figure, 21 d and 21 e are both outer peripheral structural members 21
23 and 24 are first and second shielding plates, and 27 and 31 are interior panels.

An example of the dimensional relationship of the embodiment of the present invention is 100mm
Width 3Q mm of central groove 21C of outer peripheral structural member 21 when using 100 mm pillar material, g shielding plates 23, 24
thickness of 9 mm, thickness of interior panel 27.31 4 to l
Qmm, and the thickness of the outer wall panel 25 was 12 mm.

FIG. 9 shows a perspective view of the shielding plate of the present invention attached.

When using the cutout 5 shown in FIG. 3, it is possible to use a large size cutout 32 of, for example, 2m x 1m, along with the first and second shielding plates, over the entire large section surrounded by the outer wall structure or members. can.

In this way, according to the present invention, shielding plates can be pasted over the entire wall without increasing the thickness of the wall, while leaving the internal structure and materials of the wall such as braces and frame supports in conventional wooden buildings intact. Can be attached.

Therefore, it is possible to obtain a building which has excellent shielding effects such as heat insulation and sound insulation, and which does not generate dew or ice even in cold regions or in winter, even if there is a large temperature difference between inside and outside.
