[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit with studs, and more particularly, to a building unit with studs provided with a skeleton in which columns and beams are assembled in a rectangular parallelepiped shape, and provided with studs between beams vertically opposed to the skeleton. About.

[0002]

2. Description of the Related Art In recent years, in order to increase the rate of industrialization and shorten the construction period at a construction site, a unit construction method has been used in which a plurality of building units are manufactured in a factory in advance, and these are combined at the construction site to construct a building. ing. Building units
It is manufactured by assembling pillars and beams into a rectangular parallelepiped shape to form a framework, and assembling equipment members such as flooring materials, wall materials, and ceiling materials to the framework. When a window sash or the like is attached to the side of such a building unit, a stud is provided in the framework.

As shown in FIG. 10, a stud is usually provided upright between beams 91 and 92 opposed to each other vertically, and a U-shaped plate 9 is provided.
3 and are fixed to the beams 91 and 92. That is,
The U-shaped plate 93 has a shape in which ends of a pair of side surfaces 93A are connected in a U-shape with a mounting surface 93B. In such a U-shaped plate 93, the end on the side of the opening opposite to the mounting surface 93B side is inserted into the rectangular cylindrical stud 94, and in this state, the side surface 93A is fixed to the inner surface of the stud 94. It is supposed to. When installing the stud 94, the stud 94 to which the U-shaped plate 93 is attached is connected to the beam 91,
The mounting surface 93B is connected to the beams 91 and 92 by bolts 931 and nuts 932.

When attaching a window sash to such a stud 94, as shown in FIG. 11, two studs 94 (only one is shown) are juxtaposed, and a window frame 96 is interposed between them.
And a window sill cover 97 is attached to the window sill frame 96 to form a window sill, on which a window sash is fixed. Specifically, nuts 961, nuts 961,
962 are provided, and L-shaped brackets 941 are fixed to the opposing side surfaces of the studs 94, respectively.

[0005]

In this method, the mounting surface 93B of the U-shaped plate 93 is attached to the beams 91 and 92 by bolts 93.
When tightening one, the bolt 931 had to be rotated in a narrow space sandwiched between the pair of side surfaces 93A of the U-shaped plate 93, and the workability was poor. In particular, when a rotating tool such as a wrench is used, the rotation angle is greatly limited by the side surface 93A of the U-shaped plate 93, and thus there is a problem that the working efficiency is reduced.

In addition, since the U-shaped plate 93 has a shape that is easily bent, it must be reinforced when strength is required, and if reinforced, the structure becomes complicated. There was a problem of becoming.

Further, since the window frame 96 is attached to the stud 94 via the bracket 941, two brackets 941 are provided for one window frame 96.
Must be fixed to the stud 94, so that the number of members increases and the fixing work increases.

[0008] It is an object of the present invention to provide a building unit with studs in which studs can be installed quickly and easily.
Another object of the present invention is to provide a building unit with studs that can quickly and easily install studs and can simplify the operation of attaching a window stand.

[0009]

The present invention will be described with reference to the drawings. The present invention comprises a frame 10A in which columns 11 and beams (12, 13) are assembled in a rectangular parallelepiped shape. The stud-equipped building unit 10 provided with the studs 14, wherein the end of the stud has an obliquely notched shape and is fixed to the beam via a bracket 20,
The bracket includes a fixing surface 21 protruding and fixed to the side surface of the stud in the longitudinal direction, and a mounting surface 22 provided orthogonal to an end of the fixing surface in the protruding direction and fixed to the beam. The fixing surface is fixed to a side surface opposite to the cutout side of the stud.

In the present invention, the fixing surface of the bracket is fixed to the end of the stud, and the mounting surface of the bracket is fixed to the beam. The fixing surface of the bracket is fixed to the stud by protruding in the longitudinal direction, and a mounting surface is provided at the end of the protruding direction.
A work space is formed between the mounting surface and the stud according to the height of the protrusion of the fixing surface. Also, the end of the stud has an obliquely notched shape, and the fixing surface of the bracket is fixed to the side opposite to this notched side, so the work between the mounting surface and the stud is The space is expanded by an amount corresponding to the cutout of the stud, and is greatly opened to the side opposite to the fixed surface side.

Therefore, the work of fixing the mounting surface of the bracket to the beam can be performed in a largely open work space, so that the workability is greatly improved, and the stud can be quickly and easily fixed. Further, even when the joining work between the mounting surface and the beam is performed using a rotating tool such as a wrench, the rotation is hardly limited, and a sufficient rotation angle can be secured, so that the working efficiency can be improved. .

The mounting surface is fixed to the beam by a one-way fastener 40 for connecting a plurality of members. The one-way fastener has a slit 41A at the front end and can be expanded in diameter and has a flange at the rear end. It is desirable to include a tubular fastener main body 41 provided with 41B, and a pin 42 that press-fits the fastener main body from the rear end side to expand the front end of the fastener main body.

That is, the mounting surface of the bracket is superimposed on the beam, and the fastener body is inserted through the mounting surface and the beam.
In this state, a pin is press-fitted into the fastener main body to expand the tip, and the mounting surface and the beam are sandwiched and joined between the expanded portion of the fastener main body and the flange. By using such a one-way fastener, the mounting surface and the beam can be connected and fixed without press-fitting the pin into the fastener main body and rotating like a bolt, so that the stud can be mounted more easily. .

Further, it is preferable that reinforcing ribs 23 and 24 are provided on the side edges of the fixing surface and the mounting surface, whereby a sufficient strength can be secured without reinforcement. The mounting structure can be prevented from becoming complicated, and can be easily mounted.

In the above, it is preferable that the stud is formed in a rectangular cylindrical shape, and the fixing surface is fixed to an inner surface of the stud.

That is, if the stud is formed in a rectangular cylindrical shape,
The interior space of the stud can be largely opened at the diagonally notched portion of the end of the stud. Therefore, since the work space can be configured to include the internal space of the stud, a large work space can be secured, and workability when fixing the mounting surface to the beam can be greatly improved. In addition, since the fixing surface is fixed to the inner surface of the stud, unlike the case where the fixing surface is fixed to the outer surface of the stud, no protrusion (step) due to the fixing surface is formed on the surface of the stud. Even when the fixing surface is fixed to the indoor side surface of the stud, the surface finish of the stud can be easily performed.

In this case, two studs are provided between the beams,
Receiving surfaces 15 for receiving the window sill 30 to which the window sash 4 is fixed are provided on the opposing side surfaces of these studs in a horizontal direction, and the receiving surfaces are formed by cutting and raising the side surfaces 14A of the studs. It may be formed.

In this manner, if the receiving surface is formed by cutting and raising the side surface of the stud, the number of members can be reduced because the L-shaped bracket conventionally attached to the stud to receive the window stand can be omitted. Since the operation of attaching the bracket can be omitted, the operation of attaching the window sill can be simplified.

As shown in FIGS. 5 and 6, a fixing hole 153 for fixing the window sill 30 is formed in the receiving surface 15 thus formed, and the receiving surface 1 of the pair of studs 14 is formed.
The window sill 30 is bridged between the five.

The window base 30 has a horizontal mounting surface 31 for mounting the window sash 4 (see FIG. 1), and a hanging surface 32 extending downward from an edge of the mounting surface 31 on the indoor side (inside the frame 10A). And an upright surface 33 that rises upward from the outside edge of the mounting surface 31 (outside the frame 10A), and a folded surface 34 in which the upper end of the upright surface 33 is bent toward the indoor side. The window base 30 can be manufactured by bending a plate material made of metal or the like, extruding, or the like. Windowsill 30
The end of the mounting surface 31 in the longitudinal direction is
A fixing hole 35 for coupling to the receiving surface 15 is formed on the same portion as the fixing hole 153 in the overlapped portion.

Are connected to each other by 0. The one-way fastener 40 has a structure substantially similar to the one-way fastener 40 described above (see FIGS. 3 and 4).
The same portions are denoted by the same reference numerals, and detailed description is omitted.
Here, only the connecting portion between the stud 14 and the lower window sill 30 has been described, but the upper window sill 30 (not shown) has been described.
Has a substantially similar structure, is bridged between the receiving surfaces 15 of the studs 14, and is fixed to the receiving surfaces 15.

According to this embodiment, the following effects can be obtained. That is, the fixing surface 2 of the bracket 20
1 is fixed to the stud 14 so as to protrude in the longitudinal direction, and the mounting surface 22 is provided at the end of the protruding direction, so that the height of the fixing surface 21 is between the mounting surface 22 and the stud 14. A corresponding work space is formed. The end of the stud 14 is
Since the fixing surface 21 of the bracket 20 is fixed to the side surface opposite to the cut-out side, the working space between the mounting surface 22 and the stud 14 is 14 is expanded by the cutout, and is largely opened to the side opposite to the fixed surface 21 side. Therefore, since the work of fixing the mounting surface 22 of the bracket 20 to the upper beam 12 and the lower beam 13 can be performed in a largely open work space, workability is greatly improved, and the stud 14 can be fixed quickly and easily.

Further, the one-way fastener 4 for press-fitting the pin 42 into the fastener main body 41 for joining is provided on the mounting surface 22.
0, it is fixed to the upper beam 12 and the lower beam 13 so that the mounting surface 22 and the beams 12, 13 can be connected and fixed only by press-fitting the pin 42 into the fastener body 41 without rotating like a bolt. As a result, the stud 14 can be more easily attached. Similarly, since the window sill 30 and the receiving surface 15 are also connected by the one-way fastener 40, the work of mounting the window sill 30 can be simplified, and a nut is fixed to the window sill in advance as in the prior art (see FIG. 11). You don't have to.

Since the reinforcing ribs 23 and 24 are provided on each side edge of the fixing surface 21 and the mounting surface 22, a sufficient strength can be secured without additional reinforcement, so that the mounting structure is provided. Can be prevented from becoming complicated and can be easily attached. In addition, since the fixing surface 21 and the ribs 23 are formed and fixed in a U-shape along the inner side surface of the stud 14, the number of connecting portions is larger than when only the fixing surface 21 is connected to the stud 14. , Bracket 20 to stud 1
4 can be firmly bonded.

Since the studs 14 are formed in a rectangular cylindrical shape, the interior space of the studs 14 can be largely opened at the obliquely notched portion. Therefore, stud 1
Since the working space can be configured to include the internal space of No. 4, a large working space can be secured.
The workability when fixing to 3 can be greatly improved. further,
By fixing the fixing surface 21 to the inner surface of the stud 14, a protrusion (step) due to the fixing surface 21 is formed on the surface of the stud 14 as if the fixing surface 21 was fixed to the outer surface of the stud 14. Disappears. Therefore, the fixing surface 21 is
4, the surface finish of the studs 14 can be easily performed.

The receiving surface 15 is a side surface 1 of the stud 14.
Since it is formed by cutting and raising 4A, the L-shaped bracket conventionally attached to the stud to receive the window stand can be omitted, so that the number of members can be reduced and the mounting work of the conventional bracket can be omitted. Therefore, the work of attaching the window sill 30 can be simplified.

The notch 15A for forming the receiving surface 15 is formed by using the notch forming jig 50, and the portion surrounded by the notch 15A is bent by the bending jig 60, so that the receiving jig 50 can be accurately received. The surface 15 can be formed, and the working efficiency can be greatly improved. Furthermore, the receiving member 66 is used to bend until the portion surrounded by the cut 15A abuts on the orthogonal surface 66A to form the receiving surface 15, so that the receiving surface 15 is perpendicular to the stud 14. It can be formed with high accuracy. Further, since the bent piece 641 and the receiving member 66 are formed with projections and recesses (not shown) that are fitted to each other, the receiving surface 15
, A reinforcing ridge 152 can be formed.

Conventionally, as shown in FIG. 11, a window sill cover 97 is attached to a window sill frame 96 fixed to a stud 94, and a window sill is constituted by two members. Since the window sill 30 is made of one member,
Since the number of members can be reduced and the number of steps required for installing the window sill 30 can be reduced, the working efficiency can be improved.

It should be noted that the present invention is not limited to the above-described embodiment, but includes other configurations that can achieve the object of the present invention, and the following modifications are also included in the present invention.
That is, in the above-described embodiment, the window base 30 is configured by one member. However, as illustrated in FIG. 11, the window base may be configured by a plurality of members. In the above-described embodiment, the window sill 30 is fixed to the receiving surface 15 by using the one-way fastener 40, but may be fixed by using other fasteners, for example, by being fastened with bolts and nuts. You may.

In the above embodiment, the receiving surface 15 is formed by using the notch forming jig 50 and the bending jig 60. However, the receiving surface 15 may be formed without using these jigs. Alternatively, it may be formed using only one of the two types of jigs 50 and 60.

Further, in the above embodiment, the bracket 2
Although the mounting surface 22 and the beams 12 and 13 are connected by the one-way fastener 40, they may be connected using other fasteners. For example, the mounting surface 22 and the beams 12 and 13 may be connected using a rotary fastener such as a bolt and a nut. In this connection, a joining operation is performed using a rotary tool such as a wrench. However, since a large work space is secured, the rotation is hardly restricted, and a sufficient rotation angle can be secured, so that the work efficiency can be improved.

The one-way fastener is not limited to the one described in the above embodiment, but may be any one as long as a plurality of members are joined by press-fitting a pin into the fastener main body. In implementation, it may be appropriately selected.

In the embodiment described above, the case where two studs 14 are erected is described. However, the number of studs is not particularly limited, and may be one, or three, four or more. It may be. Further, the stud is not limited to the one that fixes the window sill, and may be, for example, one that is provided for reinforcement.

A work space is formed between the mounting surface and the stud according to the height of the fixing surface. Also, the end of the stud has an obliquely notched shape, and the fixing surface of the bracket is fixed to the side opposite to this notched side, so the work between the mounting surface and the stud is The space is expanded by an amount corresponding to the cutout of the stud, and is greatly opened to the side opposite to the fixed surface side.

Therefore, since the work of fixing the mounting surface of the bracket to the beam can be performed in a large open work space, the workability is greatly improved, and the stud can be fixed quickly and easily. Further, even when the joining work between the mounting surface and the beam is performed using a rotating tool such as a wrench, the rotation is hardly limited, and a sufficient rotation angle can be secured, so that the working efficiency can be improved. .
