Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for constructing a frame wall structure for a wooden building, and basic supports and lintels used in this method.

There is a so-called "two-by-four" construction method that uses (conventional technology) to build.

In this two-by-four construction method, the component timbers are attached to the subfloor using tightening means such as nails and bolts along the contour of the wall, and the end of one of the component timbers is cut to a predetermined length from the bottom component timbers and used as a stud. Align and perpendicular to each other, arrange a plurality of them at a predetermined interval, and install the top component timbers along the other end of the stud in the same direction as the bottom component timbers so as to follow the outline of the wall to form a framework. A cloak-like flexible fibrous heat insulating material is attached by adhesive between adjacent studs between panels and inner wall panels.

(Problem to be Solved by the Invention) However, in the conventional two-by-four frame wall construction method, the mat-like flexible fibrous insulation material attached with adhesive between the outer wall panel and the inner wall panel loses its weight over time. It will sink downward under the action of , creating a large gap above. Furthermore, since a small gap is created between the side studs, the insulation properties of the wall structure of the building are inevitably deteriorated.

Therefore, an object of the present invention is to obtain a frame wall construction method that does not reduce the insulation characteristics seen in the conventional two-by-four construction method, can maintain high insulation characteristics, has good workability, and is highly robust. The purpose is to obtain the basic supports and lintels used in this construction method.

(Means for Solving the Problem) In order to achieve this object, the framed wall construction method of the present invention includes a pair of timbers made of standard construction timbers facing the outside and inside of the wall, and at least Of the basic pillars, the gap filler has a shape self-retaining and heat insulating gap filler with a central keyway extending vertically on one side end surface, and a means for integrally connecting the wood and the gap filler. A basic post with a central keyway on the side end faces on both sides is arranged perpendicularly as a stud at a predetermined interval to the constituent timber having a width equal to the thickness of the basic post, and the spacing between the studs is , and has a thickness equal to the thickness of the basic strut, and is provided with a central keyway extending longitudinally on both side end surfaces, and gap filler panels made of the same material as the gap filler are mutually connected. A key spline made of the same material as the gap filler is placed between opposing sides of adjacent studs, and inserted into the closed vertically extending space created between the opposing gap fillers and the central keyway of the gap filler panel. However, at the right-angled corners of the wall, a basic column with a center key groove provided only on the inner side end surface of the gap filler is installed as an end column, and the top surface of the closed wall structure constructed in this way is characterized in that it consists of installing structural timbers along which the width is equal to the thickness of the base strut.

The basic support used in the framed wall construction method of the present invention consists of a pair of standard construction timbers facing the outside and inside of the wall, and a center that is placed between these timbers and extends vertically on at least one side end surface. It is characterized by having a shape-retaining and heat-insulating gap filler provided with a keyway, and a means for integrally connecting the wood and the gap filler.

Furthermore, the lintel used in the framed wall construction method of the present invention consists of a pair of wooden boards of the same shape facing the outside and inside of the wall, and a gap filler with self-shape characteristics and heat insulation properties installed between these boards. It is characterized in that it has the same thickness as the basic strut used for the studs, and has a horizontal length that engages a pair of opposing notches formed in a pair of adjacent studs.

(Function) According to the framed wall construction method of the present invention, the frame is assembled using basic supports in the same way as the conventional two-by-four construction method is assembled using standard component timber, and the insulation material between the studs is attached to the outer wall panel and inner wall panel. Rather than attaching a mat-like material with adhesive, a self-shape insulating gap filler panel is placed between the studs to fill the closed space created between the gap filler of the basic column and the center keyway of the gap filler panel. Press fit the key spline and install. This key spline crosses the interface between the studs and the gap panel, ensuring that air flow between the outside and inside of the wall structure is blocked, even if there is a gap at this interface. At the same time, it also acts as a wedge to firmly hold the gap filler panel between the studs.

(Example) Next, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a perspective view of a portion of a right-angled corner and a portion provided with a lintel of a wall structure constructed by the framed wall construction method of the present invention.

According to the present invention, the basic support 1 is used as a stud and an end support, like the standard constituent timber of the conventional two-high-four construction method.
Lateral (horizontal) with a width equal to the thickness of the base strut
Install between the bottom and top constituent timbers that extend to the bottom.

As shown in FIG. 2, the basic support 1 is formed into an integral structure by connecting two stages with, for example, a self-retaining and heat-insulating gap filler 1b sandwiched therebetween. The thickness of this gap filler is, for example, 2-
'' (64nrm), and the width is a standard groove.The connecting means is made of an adhesive that adheres the standard component wood 1a and the gap filler 1b and/or that engages both standard component materials (gi, bolt donut, self-tapping screw, etc.). Alternatively, it may be configured by a tightening means such as a band. (The tightening means such as the girdles 11 are preferably attached at at least three points spaced apart from each other along the longitudinal center line of the constituent wood.

The gap filler 1b is preferably made of expanded polystyrene (styrene foam), for example, but any material may be used as long as it has shape self-retention and heat insulation properties.

When the basic column 1 is used as a stud, and when the gap filler 1 is used as an end column 1', a basic column is used in which a center keyway is provided only on one side end surface of the gap filler.

Between adjacent studs, a heat insulating gap filling panel 3 made of the same material as the gap filling material of the basic struts, for example, made of expanded polystyrene, is arranged. The thickness of this gap filling panel 3 shall be the same as that of the basic struts, and the width approximately equal (slightly larger) to the spacing between the studs, and the length equal to the length (height) of the studs. Make it. Furthermore, a center keyway 4 similar to the center keyway in the gapfiller of the basic column is provided along the longitudinal center line on both side end faces of the gap filler panel. When the gap filler panel is placed between adjacent studs, a closed longitudinally extending space is created between the center keyway 2 of the gap filler 1b of the basic strut and the center keyway 4 of the gap filler panel 3; do. An electrical wiring groove 6 can be provided as appropriate on the side surface of the gap filling panel 3 on the inner wall side.

The key spline 5 is also press-fitted into the closed space created between the center keyway 2 between the stud 1 and the gap filler of the end support 1'.

The insulation properties are further improved if the interface between the gap filler panel and the surrounding components is covered.

In the part corresponding to the door or window, notches are provided in the mutually opposing side end surfaces of the upper part of the mutually adjacent studs of this part, and each end of the lintel 7 is engaged with this notch, and nails or tapping are provided. Secure with tightening means such as screws.

Like the basic support, this lintel 7 is composed of a pair of wooden boards 8 and a gap filler 9 attached between these planks, and has the same thickness as the basic support, in this case, Tightening means such as nails 11 are engaged with both plates at a plurality of positions spaced apart from each other along the lateral (horizontal) center line, and are integrally constructed.

FIG. 3a shows an assembly method for corners that are not at right angles, and the end struts used for such corners are obtained by cutting the basic strut 1 diagonally as shown in FIG.

4a, b, and c, a component lumber 20 having a width equal to the thickness of the basic support 1 and the same thickness as the standard component lumber 1a of the basic support 1 is attached to the upper end of the stud with a nail 11. This shows how to secure the product using a tightening means such as the following.

Figures 5a, b and c show how the structural timber 20 at the right angle corner is secured to the upper end of the end support 1' by means of fastening means such as nails 11.

FIGS. 6a, b, and c show a method of fixing the studs 1 and the upper and lower structural timbers 20 in the lintel area using tightening means such as nails 11.

FIG. 7 shows the foundation 21, screws 22, and subfloor 23.
and the right-angled corners of the framed wall according to the invention.

FIG. 8 shows a method of fixing the bottom structural timber 20 to which the lower end of the basic support is attached to the subfloor 23 and the bead 22 using tightening means such as nails 11.

In order to increase the strength of the basic strut against loads from the width direction, in a preferred embodiment of the present invention, side edges of metal strips 10 having a length equal to the length of the standard structural timbers are provided between the standard structural timbers 13. Press fit into the opposing standard constituent wood 1a,
Gap fillers are attached to both sides of this metal strip 10 using an adhesive.

Reinforced elementary struts constructed in this manner are particularly suitable for use as end struts, the assembly stages of which are shown in FIGS. 9a, b and c.

(Effects of the invention) Compared to the conventional two-high-four construction method, the frame wall construction method of the present invention uses double-stand basic supports made of double standard construction timber, so the strength is improved, and even wooden structures with three floors You will be able to construct buildings.

In addition, instead of attaching the insulation material between the studs by gluing a mat-like flexible insulation material (glass wool) to the exterior or interior wall panels as in the past, we have installed a self-retaining insulation material such as expanded polystyrene. By arranging the gap panel between the studs and press-fitting the key spline into the space created by the central keyway, it can be fixed easily and quickly, reducing the construction period.

Furthermore, since the gap-filling panel has shape self-retention properties, it does not sink like glass wool over time, and can reliably seal the boundary between the gap-filling panel and the studs. The presence of key splines across the interface between adjacent members acts as a labyrinth seal, improving thermal insulation properties.
