[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skeleton structure of a building unit, and can be used particularly when building a building such as a house.

[0002]

BACKGROUND ART In recent years, unit-type buildings such as houses in which building units produced in advance in a factory are transported to a construction site and a plurality of building units are combined therein to be built therein are increasing. As shown in FIG. 9, a building unit 80 manufactured in a factory in advance has four pillars 2 standing vertically at four corners, and long-side beams 4 and short-side beams connecting the upper ends of these pillars 2 with each other. A frame 81 having an upper beam 6 made of 5 and a lower beam 3 made of a long side beam 3A and a short side beam 3B connecting the lower ends of the columns 2 is provided, and the frame 81 has a ceiling material, a floor material and an inner wall. It is manufactured in the shape of a rectangular parallelepiped as a whole by attaching the outer wall and the like.

However, even if a plurality of such building units are combined, since each building unit has a rectangular parallelepiped shape, the entire unit-type building that is completed is also angular and the appearance is monotonous. As a technique shown to solve this problem, the actual fair 4-
No. 52325 is cited.

The structure of the ramen unit shown in this publication is, as shown in FIG. 10, four pillars 91 arranged vertically.
Is composed of two short pillars 91A and 91A and two long pillars 91B and 91B, and four lower beams are provided between the lower ends of these four pillars 91.
Short columns 91A, 91A and long columns 91 combined at 92
The upper beams 93 are connected between the upper ends of B and 91B, and the intermediate beams 94 of the same length as the upper beams 93 are connected to the positions of the long columns 91B and 91B at the height positions of the columns 91A, 91A and 91B. , 91B,
Both ends of the long columns 91B, 91B and both ends of the intermediate beam 94 are connected by horizontal beams 95, and both ends of the shorter columns 91A, 91A and both ends of the intermediate beam 94 are connected by inclined beams 96, and an inclined portion is provided between them. There is.
That is, the side surface of the ramen unit 90 has a pentagonal shape. Then, by combining such a side-pointed pentagonal-shaped ramen unit 90 and an ordinary rectangular parallelepiped-shaped ramen unit, it is intended to obtain a unit-type building having a changed appearance.

[0005]

However, in the above-mentioned ramen unit, the intermediate beam 94 is provided at the intersection of the horizontal beam 95 and the inclined beam 96. For that purpose, first, the horizontal beam 95 and the inclined beam 96 are provided. After 96 and 96 are joined by welding, the welded portion will not work as it is and the intermediate beam 94 will be difficult to attach. Therefore, the welded portion must be finished smoothly. Since the intermediate beam 94 must be attached after that, the intersection becomes complicated, and the work up to that point is troublesome and time-consuming.

Further, in the smooth finishing work of the welded portion of the horizontal beam 95 and the slanted beam 96, it is difficult to obtain the flatness of the portion to be finished.
There was also a problem that it was difficult to install the with high accuracy.

An object of the present invention is to provide a skeleton structure for a building unit in which an intermediate beam can be attached easily and accurately.

It is formed so as to project from the width of 12. Further, on the lower surface of the lower flange portion 13 of each of the beams 40A and 40C, a lower coupling plate 14 wider than the width thereof is provided. The beams 40A and 40C are welded to each other such that the upper flange portion 12 is welded to the short side protrusion of the inner coupling plate 11 and the lower flange portion 13 is welded to both sides of the lower coupling plate 14. It is designed to be combined with.

The connection between the intermediate beam 7 and the horizontal beam 40A is made at the intersection point P.

It is fixed by 18.

As shown in FIG. 2, on the upper surface of the intermediate beam 7,
A bracket 16 supporting a roof panel 8 forming the roof of a unit-type building is fixed by a bolt 17. The roof panel 8 is supported along the upper surface of the inclined beam 40B with the same inclination as that of the inclined beam 40B. Also, the bracket 16 is
The upper flange portion 16A, the lower flange portion 16B, and the web portion 16C connecting them are formed in a substantially U shape, and the upper flange portion 16A has the same inclination as that of the roof panel 8 to which it is attached. .

The connection between the inclined beam 40B and the short columns 2A, 2A is performed at the connecting position P3 as shown in FIGS. 5 and 6, and the structure of the connecting portion is such that the inclined beam 40B has a cross section at its end. A substantially L-shaped coupling plate 20 is attached in a shape protruding toward the short column 2A. On the other hand, at the upper ends of the short columns 2A, 2A,
A bracket 23 is attached which engages with the coupling plate 20. The bracket 23 is integrally formed by a contact plate 24 fixed to the pillar 2A by welding or the like, a mounting plate 25 fixed orthogonally to the contact plate 24, and reinforcing ribs 26 of both. The mounting plate 25 and the coupling plate 20 are bolts,
It is joined by a nut 27.

Further, as shown in FIG. 5, a roof support bracket 30 for supporting the end portion of the roof panel 8 is attached to the short side beam 5 fixed to the upper end portion of the short column 2A. The roof receiving bracket 30 is formed by a receiving plate 31 having a vertical portion 31A and an inclined portion 31B, and a reinforcing rib 32.
31A is fixed to the short-side beam 5 by bolts and nuts 33, and the inclined portion 31B is formed so as to be substantially perpendicular to the mounting angle of the roof panel 8. A stiffener 5A that reinforces the strength of the short side beam 5 to which the roof receiving bracket 30 is attached is fixed.

In order to construct the frame structure 1 of such a building unit, the short pillars 2A, 2A and the long pillars 2B, 2B are connected at their upper and lower ends by short-sided beams 3B, 5 respectively to form two gable sides. Along with manufacturing the panels 50 and 51, a long side beam 3A for connecting the lower end portions of the panels 50 and 51 to each other, and a floor panel 52 having joists or the like attached to the 3A, and a length for connecting the upper end portions to each other. A ceiling panel 53 in which the intermediate beam 7 and the small beam 53A are attached to the side beam 4 is manufactured. Here, when manufacturing the ceiling panel 53, the horizontal projecting beam 40C is welded to the tip of the inclined beam 40B via the coupling plate 10 in advance. Then, the horizontal projecting beam 40C and the horizontal beam 40A in this state are connected to the inner connecting plate 11
And the lower joining plate 14 for welding and joining at the joining position P1.

Next, the floor panel 52 and the ceiling panel 53 are
Each is connected to two wife side panels 50 and 51 to form the frame structure 1 of the building unit. Here, when mounting the ceiling panel 53, one end of the horizontal beam 40A is attached to the long pillar of the end panel 51.
After welding and fixing to 2B and 2B, the other end is the short column 2 of the end panel 50.
Install by tightening bolts to brackets A and 2A.

The frame structure 1 thus manufactured
A floor unit, a ceiling unit, an inner wall, an outer wall, etc. are attached to the building to produce a building unit with an inclined surface at the top. Then, such a building unit is carried into a construction site and appropriately combined with a rectangular parallelepiped building unit or the like to construct a unit-type building. In this unit type building, when attaching the roof panel 8 to the inclined surface of the building unit, the bracket 16 for supporting the roof panel 8 is fixed to the intermediate beam 7, and the roof receiving bracket 30 is fixed to the short side beam 5, The roof panel 8 is attached to the brackets 16 and 30.

According to this embodiment as described above, there are the following effects. That is, the intermediate beam 7 includes the horizontal portion 4A and the inclined portion.
Since it is mounted at a mounting position P2 distant from the intersection point P with 4B, and both ends are attached to the mounting plate 15 with bolts 17, smooth finish after welding is unnecessary as compared with the welding mounting performed at the intersection point P. Work is easy.

Further, since the intermediate beam 7 is provided at the mounting position P2 distant from the intersection P between the horizontal portion 4A and the inclined portion 4B,
Compared with the case where the intermediate beam is provided at the intersection P, there is also an effect that another beam for supporting the bracket 16 need not be provided.

Furthermore, if the two long-side beams 4 and 4 are first joined by the intermediate beam 7, the long-side beams 4 and 4 are partially fixed, so that the small beam 53A can be easily attached, and therefore the ceiling panel 53 is easy to make.

Further, the connection between the horizontal beam 40A and the slanted beam 40B constituting the long side beam 4 of this embodiment is such that both ends of the horizontal beam 40A and the projecting horizontal beam 40C at the tip of the slanted beam 40B at the connecting position P1. , The inner coupling plate 11 and the lower coupling plate 14 are interposed, both beams 40A and 40C and both coupling plates 11 and 14 are kept horizontal, and are coupled by welding,
Horizontal beams compared to welding and joining diagonal cuts
It is easy to connect the 40A and the inclined beam 40B, and the mounting accuracy is high.

Further, the inner connecting plate 11 and the lower connecting plate 14 for connecting both ends of the horizontal beam 40A and the projecting horizontal beam 40C are wider than the both beams 40A and 40C, and therefore, the both beams 40A. , 40C upper flange part 12 is on the protruding part of the inner connecting plate 11, and lower flange part 13 is on the lower connecting plate 14
Since the protrusions on both sides of the can be welded downward, the workability is good and the joining work is easy.

When the roof panel 8 is provided on the inclined beam 40B, the bracket 16 can be attached to the intermediate beam 7, so that the roof panel 8 is temporarily placed between the width centers of the building units.
Even if the layout is done, the bracket 16 can evenly support the end portion of the panel 8, so that the roof panel 8 can be freely allocated.

By the way, in FIG. 9, when the roof panel is attached along the inclined portion, the bracket cannot be attached on the intermediate beam. Considering the tilt from the lower side of the eaves, it is preferable to provide it on the long side beam as close as possible to the intermediate beam. However, in this case, if the roof panel is allocated between the width centers of the building units, the allocated end of the roof panel must be supported, and in order to accommodate it,
It is uneconomical because it requires another beam separate from the intermediate beam.

The present invention is not limited to the above-mentioned embodiments, but includes the following modifications. That is, in the above-described embodiment, the intermediate beam 7 is provided on the horizontal beam 40A at the mounting position P2 at a position separated from the intersection P on the side of the long pillar 2B by a predetermined distance.
It suffices that 2 is a position away from the intersection point P, for example, in FIG.
As shown in, the frame structure 1A of the building unit may be attached to the inclined beam 40B at a position distant from the intersection P on the short column 2A side.

Further, in the above-mentioned embodiment, the frame structure inclining in the short side direction of the building unit is adopted, but the structure is not limited to this,
For example, as shown in FIG. 8, a frame structure 1B of a building unit that inclines in the long side direction may be used. That is, in this embodiment, the intermediate beam 7A is formed to have the same length as the long-side beam 60, and the short-side beam 61 is formed of the horizontal portion 61A and the inclined portion 61B.
Then, the intermediate beam 7A constitutes the frame structure 1B of the building unit attached to the attachment position P2 at a position separated from the intersection P on the long column 2B side by a predetermined distance. Also in the frame structure 1B of such a building unit, the intermediate beam 7A may be provided at the inclined portion 61B at a position away from the intersection P on the short column 2B side.

Further, in the above-mentioned embodiment, the roof panel 8 is provided on the inclined surface formed across the inclined portions 4B. However, the present invention is not limited to this, and the inclined portion 4B may be used as a light window or a separate window, for example. May be used for the purpose of

Further, in the above-described embodiment, when the frame structure 1 of the building unit is formed, the horizontal beam 40A and the horizontally projecting beam 40C of the inclined beam 40B are welded to each other at the connecting position P1 to form the connecting position P1.
Although the ends of the slanted beams 40B and the short columns 2A are bolted to each other at 3, the present invention is not limited to this, and they may be reversed, for example. That is, the horizontal beam 40A and the horizontal protruding beam 40C may be bolted at the connecting position P1, and the end of the inclined beam 40B and the short column 2A may be welded at the connecting position P3.

In addition, the specific structure and shape for carrying out the present invention may be other structures as long as the object of the present invention can be achieved.
