Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a joint structure between a lightweight concrete panel and a wooden material, and can be used for a building such as a house using a wood material as a main structure.

(Background technology)

2. Description of the Related Art Conventionally, in a building such as a house, a wooden material is often used for a main structure such as a pillar or a beam or a wall material.

In particular, in Japan, wood-based houses have been popular since old days because of the favorable texture of the skin and the natural ventilation and the comfort in humid climates. For this reason, there is a merit that a technique related to a wooden building is widely and widely used, and a building technician (a so-called carpenter) can relatively easily secure the technique.

On the other hand, in recent years, in addition to the tendency to increase the heat insulation and airtightness based on the development of air conditioners, concrete-based materials with high airtightness are used to prevent neighborhood noise caused by crowded houses. It has become so. For example,
Light-weight cellular concrete, abbreviated as PALC or ALC, is widely used in the field of home building. This lightweight concrete is generally used as a panel material for a wall material or the like, and is usually fixedly supported by a bolt or the like via a fixture on a frame or the like using a lightweight steel frame.

[Problems to be solved by the invention]

By the way, since the lightweight concrete as described above is light in weight, it can be used for building a wooden structure. However, when joining a panel made of lightweight concrete to a wooden structural material, a conventional mounting fixture for a steel structure cannot be used. For this reason, a structure in which the panel is held by a box-shaped metal member bolted to a wooden structure is employed. However, since an exposed portion is generated, there is a problem in appearance, and a load tends to concentrate on the mounting portion. In particular, wood has a property that it is strong against pulling in the grain direction but relatively weak against intensive bending and compression, and there has been a strength problem with the conventional fixture.

SUMMARY OF THE INVENTION An object of the present invention is to provide a joint structure between a lightweight concrete panel and a wooden material which can secure strength by dispersing a concentrated load at a joint portion and has a simple structure and good appearance.

[Means for solving the problem]

The present invention embeds in a lightweight concrete panel a metal contact member having a contact surface exposed at a joint surface of the panel and a connection surface exposed at a surface crossing the joint surface. A metal receiving member having a receiving surface exposed at a joint surface of the frame is embedded in a frame made of a wooden material, and a connecting member intersecting with the frame is arranged along one side of the receiving member. The contact surface and the receiving surface are brought into surface contact with each other, and the connecting member is fixed to the connecting surface of the contact member, thereby forming a joint structure between the lightweight concrete panel and the wooden material.

Here, as the connecting member, a structure in which the panel and the frame are fixed by welding or the like to the side surface of the receiving member or the like and the end is connected to the abutting member can be used. By connecting both ends to the connection surface of the panel joined to the opposite side of the frame, a structure in which the frame is clamped and fixed by both panels can be used.

Further, as the contact member and the receiving member, a metal plate bent into a substantially L-shaped or substantially U-shaped cross section in which a connecting surface intersects a connecting surface from the abutting surface or a surface on which the connecting member is arranged from the receiving surface intersects, respectively. It is preferable to disperse the load in such a manner as to be closely fixed to the two surfaces of the panel and the frame with a large area on the back side of each.

Furthermore, the contact member and the receiving member may have a contact surface and a receiving surface that are substantially the same as the surrounding joint surface where each is disposed,
Alternatively, it is preferable to arrange them so as to protrude slightly.

[Operation] In the present invention as described above, the mutual load is applied between the contact member and the panel, and between the contact member and the frame by bringing the contact surface on the panel side and the receiving surface on the frame side into contact with each other. It can be received over the entire contact surface, and the concentrated load on each is dispersed. In addition, since the fixing between the panel and the frame is performed by connecting and fixing the contact member and the receiving member with the connecting member, the possibility of causing a concentrated load is smaller than in a case where bolts or the like are directly used for each. Thus, strength problems are improved.

Furthermore, the simple structure using the contact member of the panel, the receiving member of the frame, and the connecting member prevents the appearance from being impaired because the contact member and the receiving member are buried, thereby achieving the above object. You.

〔Example〕

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a wall portion 1 of a house to which the present invention is applied. A plurality of beams 10 which are frames made of wood are arranged in parallel in the horizontal direction. A plurality of panels 20 made of lightweight cellular concrete are arranged.

As shown in FIG. 2, these panels 20 have upper and lower end faces 21 which are bonding surfaces bonded to upper and lower surfaces 11 which are bonding surfaces of the beam 10, respectively. And these surfaces 11 and end faces
In joining with 21, the joining structure of the present invention is adopted.

As shown in FIGS. 3 and 4, the beam 10 is formed by laminating two laminated timbers 12 together. Laminated timber 12
The inner surface 13 of the lamination from the upper surface 11
Is formed to reach the lower surface 11, and a receiving member 40 formed by bending a metal plate into a substantially U-shaped cross section is fitted in the concave portion 14. This receiving member 40
Are formed such that the receiving surfaces 41 at both ends of the U-shape are slightly flush with the surface 11 respectively. In addition, the intermediate portions 42 connecting the receiving surfaces 41 are respectively disposed at positions deeper than the inner side surface 13, and when the two glued laminated timbers 12 are laminated, a gap 43 at a predetermined interval between the respective intermediate portions 42 is formed. It is formed.
A connecting member 44 having a thickness substantially equal to or slightly larger than the interval between the portions is penetrated through the gap 43.

As shown in FIG. 5, the panel 20 includes an end face 21 and a side face 22.
The notch 23 is formed over the
Inside, a contact member 50 formed by bending a metal plate into a substantially L-shaped cross section is disposed. This contact member 50 is L
One of the U-shaped contact surfaces 51 is formed so as to protrude slightly from the same surface as the end surface 21 of the panel 20. Further, the other connecting surface 52 is arranged along a surface parallel to the side surface 22 inside the notch 23.

Here, the contact member 50 is integrally fixed in advance when the panel 20 is formed, and is connected to the reinforcing member 24 in the panel 20 by welding before forming. The notch 23 is also formed in accordance with the contact member 50 when the panel 23 is formed.

Returning to FIG. 2, when the panel 20 and the beam 10 are joined, the contact surface 51 of the contact member 50 contacts the receiving surface 41 of the receiving member 40. The upper and lower ends of the connecting member 44 penetrated by the beam 10 are inserted into the cutouts 23 of the panel 20, respectively.
Along the connection surface 52 of the contact member 50, the contact member 50 is penetrated and fixed by a plurality of screws 45. These form a joint structure between the panel 20 and the beam 10.

In the present embodiment configured as described above, bonding is performed in the following procedure.

First, the end surface 21 of the panel 20 is brought into contact with one of the upper and lower surfaces 11 of the beam 10, and the joining position is adjusted so that the contact surface 51 of the contact member 50 contacts the receiving surface 41 of the receiving member 40.

Next, the connecting member 44 is passed through the space 43 between the beams 10, and the leading end thereof is inserted into the cutout portion 23 of the panel 20 so as to be along the connecting surface 52 of the contact member 50. In this state, a plurality of screws 45 are screwed into the connection surface 52 through the tip of the connection
And the contact member 50.

Subsequently, the end surface 21 of another panel 20 is attached to the other surface 11 of the beam 10.
To the contact surface 51 of the contact member 50 and the receiving surface 41 of the receiving member 40.
And the beam in the notch 23 of the panel 20
The other end of the connecting member 44 projecting from 10 is inserted and fixed with screws 45.

Thus, the upper and lower panels 20 are connected with each other by the connecting members 44 of the contact members 50, and are fixed while holding the beam 10. In addition, the connecting member 44 penetrates the beam 10, whereby the beam 10 and each panel 20 are securely fixed.

According to this embodiment, the following effects can be obtained.

That is, when the beam 10 and the panel 20 are joined, mutual load can be received by the contact between the contact surface 51 of the contact member 50 and the receiving surface 41 of the receiving member 40.

For this reason, the load applied to the beam 10 is received by a large area on the back side of the receiving member 40, and the deformation of the beam 10 due to the concentration of the load can be prevented.

In particular, since the receiving member 40 is substantially U-shaped and the load from one panel 20 is released to the other panel 20 via the member 40, the load applied to the beam 10 can be further reduced, Even if wood is used for 10, the strength problem can be solved.

Further, the load applied to the panel 20 side is received by a large area on the back side of the contact member 50, and it is possible to prevent the panel 20 from cracking due to the concentration of the load.

In particular, since the contact member 50 is welded to the reinforcement 24 of the panel 20, the load applied to the contact member 50 can be more widely dispersed.

Furthermore, the panel 20 and the beam 10 are fixed by connecting the contact member 50 and the receiving member 40 by the connecting member 44, and
Since it is performed by sandwiching the bolts 10, the possibility of causing a concentrated load is smaller than in the case where bolts or the like are directly used, and the strength can be further increased without cracking or the like.

Further, the connecting member 44 is disposed so as to penetrate the beam 10, so that the panel 20 and the beam 10 can be prevented from being displaced in the direction of the joint surface of each other, and can be securely fixed.

Further, the receiving members 40 are fitted to the inner side surfaces 13 of the two glued laminated lumbers 12, respectively, and these are adhered to each other to form the beam 10, so that the gap 43 through which the connecting member 44 passes is reinforced by the receiving members 40 on both sides. In other words, sufficient strength can be obtained even with torsion.

On the other hand, in the above embodiment, the beam 10 and the panel 20 can be joined to each other with a simple structure using the contact member 50 on the panel 20 side, the receiving member 40 and the connecting member 44 on the beam 10 side.

The contact member 50 can be buried in advance when the panel 20 is formed.
Even the fitting of the 40 or the bonding of the glued laminated lumber 12 can be performed in advance. For this reason, the number and types of components to be carried into the site can be reduced, work at the site can be significantly reduced, and construction efficiency can be increased.

Furthermore, in the joined beam 10 and panel 20,
Only the portion inside the cutout portion 23 of the panel 20 in the above-mentioned joint structure is only visible from the outside, and the portion can be covered with a suitable lid material, filler, etc., so that the appearance is extremely good. Can be.

The present invention is not limited to the above embodiment, but includes the following modifications.

That is, the beam 10 is not limited to the glued laminated lumber 12, but may be ordinary wood, and its size, shape, and the like may be appropriately set in practice.

In the above embodiment, the connecting member 44 is simply penetrated through the beam 10, but the connecting member 44 may be welded and fixed to the receiving member 40 as appropriate.

Further, the receiving member 40 is not limited to the substantially U-shape, and may be any shape as long as the receiving member 40 comes into contact with the panel 20 with a large area. However, considering the simplification of the structure and the point that the load can be released, it is preferable to use the receiving member 40 as in the above-described embodiment.The beam 10 is not limited to the structure in which the two laminated timbers 12 are bonded, A recess in the upper and lower surfaces or one side of a single piece of wood
And the receiving member 40 may be fitted. In this case, the connecting member 44 is biased toward the one side surface of the receiving member 40, and accordingly, the notch 23 of the panel 20 is made shallow, and the connecting surface 52 of the abutting member 50 is similarly biased, so that at the time of joining, What is necessary is just to adjust so that it may overlap with each other.

On the other hand, in the above-described embodiment, the contact member 50 is
, But they may be separately constructed.

Although the contact member 50 is buried integrally when the panel 20 is formed, a cavity corresponding to the contact member 50 is provided when the panel 20 is formed, and the contact member 50 is later provided in this portion.
May be fixed. However, it is more advantageous in terms of strength to integrally mold and weld to the bar 24 as in the above embodiment.

Further, the contact member 50 is not limited to the substantially L-shape, and may be any shape that is in contact with the panel 20 with a wide area, for example, may be a substantially U-shape or the like. It may be used for fixing to the panel 20 by bending it into an appropriate shape or the like.

Further, the connection between the contact member 50 and the connection member 44 is not limited to the screw 45, but may be any suitable means such as using a strong adhesive or the like.

Furthermore, the joint structure of the present invention is similar to that of the above-described embodiment.
The present invention can be widely used not only for joining the panel 10 and the wall material panel 20 but also for joining the lightweight concrete panel and the wood material in various parts such as the beam 10 and the floor panel or the panel 20 and the column.

[Effects of the Invention] As described above, according to the joint structure of the lightweight concrete panel and the wooden material of the present invention, the concentrated load at the joint portion can be dispersed and the strength can be ensured, and the structure can be simplified to reduce Workability can be improved, and appearance can be improved.
