Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a trapezoidal unit of a unit house, and can be applied to a unit house having a roof adapted to the so-called north diagonal restriction.

[Background technology]

Some conventional houses have roofs formed to satisfy the northern diagonal line restriction regulations, and in such houses, the roofs are formed by cutting out a portion of the top floor.

This north diagonal line restriction also applies to unit housing built by assembling multiple housing units. For this reason, among the box-shaped housing units that make up unit housing, there are trapezoidal units in which one of the upper corners is cut out diagonally.

FIG. 3 shows a frame 2 of a trapezoidal unit 1 as an example.

In the figure, each pair of long columns 11 and short columns 12 are arranged at the four corners of the trapezoidal unit 1, and the lower ends of the long columns 11 and short columns 12 are the lower short sides of each pair of oppositely arranged columns.粱1
3 and the lower long side wire 14.

Further, the upper ends of the long columns 11 are connected to each other by an upper short side beam 15, and the upper ends of the short columns 12 are connected to each other by a small beam 16.

A horizontal beam 17 and a diagonal beam 18 are arranged between the upper ends of these long columns 11 and short columns 12.

One end of the horizontal beam 17 and the diagonal beam 18 are connected to the long column 11 and the short column 12, respectively, and the other ends are butted against each other and connected, as shown in FIGS. 4 and 5. .

In the figure, the horizontal beam 17 and the diagonal beam 18 form an angle θ within a plane that includes the horizontal beam 17 and the diagonal beam 18 among the planes of the upper and lower surfaces and each side surface of the trapezoidal unit 1, and are connected via a joining plate 30. has been done.

This joining plate 30 includes a horizontal beam 17 and a diagonal beam 1.
A small beam 19 is joined to both of the parts 8 at right angles. Furthermore, gusset plates 31 and 32 are joined to the ends of the horizontal beam 17 and the diagonal beam 18, respectively. These gusset plates 31, 32 are provided with diagonally extending braces 2 to increase the rigidity of the framework 2.
0.21 ends are each bolted.

[Problem to be solved by the invention]

In such a trapezoidal unit l, the gusset plate 31
．． 32 are each connected only to beams 17 and 18, so
The joint strength of the gusset plates 31.32 is low, and therefore the joint strength of the braces 20.21 to the framework 2 is also low. For this reason, there is a problem that the rigidity of the frame 2 cannot be made sufficiently strong by the braces 20 and 21.

In addition, when welding the horizontal beam 17 and the diagonal beam 18 to the joint plate 3°, it is necessary to weld while maintaining the angle θ between the horizontal beam 17 and the diagonal beam 18, which makes the welding work complicated. There is also the problem.

A first object of the present invention is to provide a trapezoidal unit for a housing unit, which can increase the strength of bonding the brace to the frame and increase the rigidity of the frame by the brace.

A second object of the present invention is to provide a trapezoidal unit for a unit house that facilitates welding of horizontal beams and diagonal beams to a joining plate.

[Means to solve the problem]

A first aspect of the present invention is that the frame includes a horizontal beam, a diagonal beam connected to the horizontal beam at an angle in the same plane via a joint plate, and the horizontal beam and the diagonal beam connected to the joint plate. In the trapezoidal unit configured to include small beams connected at right angles, and in which a gusset plate connecting the brace is connected to the horizontal beam, the gusset plate is also connected to the connection plate. It is a feature.

Further, in a second aspect of the present invention, the joining plate and the gusset plate are joined by fitting the notches formed in these plates to each other, and the gusset plate is connected to the gusset plate. having two extending parts extending from the notch in both directions of the horizontal beam and the diagonal beam and being joined to the horizontal beam and the diagonal beam;
A feature is that these extending portions are provided with connecting portions of the brace.

[For production]

In the present invention, since the gusset plate is joined to both the beam and the joint plate, the joint strength of the gusset plate to the frame of the trapezoidal unit is increased.
As a result, the bonding strength of the brace to the frame also increases.

Further, by providing notches in each of the joining plate and the gusset plate, when welding the joining plate and the gusset plate, these notches can be fitted together to temporarily fasten both plates. .

Furthermore, by providing two extensions on the gusset plate that extend to both the horizontal beam and the diagonal beam, welding of the horizontal beam and the diagonal beam to the joint plate can be done easily. This welding work can be done easily with the beam placed on it.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In the following description, the same reference numerals will be used for the same members as those already described, and the description thereof will be simplified or omitted.

FIG. 1 shows the main part of this embodiment, and this part corresponds to the joint part A where the beams 17 to 19 shown in FIG. 3 are joined.

In the figure, the horizontal beam 17, the inclined beam 18, and the small beam 19 are each made of channel steel or the like having a U-shaped cross section. The ends of these beams 17 to 19 are joined to each other via a joining plate 23.

A gusset plate 24 is welded and integrated with the joint plate 23, and one end of the brace 20.21 is bolted to this gusset plate 24.

As shown in FIG. 2, the joining plate 23 is a plate-like member made of two steel plates or the like, and has a notch 25 extending in the horizontal direction near the upper end in the figure. On the other hand, the glass set plate 24 is formed by bending a steel plate or the like at an angle θ in advance, and has a notch 26 that fits into the notch 25 of the joint plate 23 . This notch 2
5.26, the gusset plate 24 can be temporarily fixed to the joining plate 23.

Further, the gusset plate 24 is provided with two extending portions 24A and 24B extending from the cutout portion 26 in the direction of the horizontal beam 17 and the diagonal beam 18, respectively. A horizontal beam 17 and a diagonal beam 18 are connected to these extending portions 24A and 24B by welding, respectively. extension part 24A,

That is, since the gusset plate 24 is integrated with the joining plate 23 and the gusset plate 24 is joined to all of the horizontal beam 17, the diagonal beam 18, and the joining plate 23, the set plate 24 is connected to the frame 2 of the trapezoidal unit l. Brace 20.2
The connection strength of 1 to 17 and 18 can be increased.

Furthermore, by integrating the gusset plate 24 and the joint plate 23, only the joint plate 23 is interposed between the small beam 19 and the gusset plate 24, so that the joint plate 30 and the beam 17°18 are Unlike the case where the small beam 19 is connected to the set plate 31, 32 through the
The connection strength to the small beam 19 of 0.21 can also be increased.

Furthermore, since the horizontal beam 17 and the diagonal beam 18 are also connected to each other by the gusset plate 24, the horizontal beam 17
