Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a building unit, and more particularly to a trapezoidal unit capable of accommodating a prefabricated building within a slanted line limit.

[0002]

2. Description of the Related Art Conventionally, a unit construction method often used for building a building such as a house is to produce a building unit such as a rectangular parallelepiped unit or a trapezoidal unit in a factory in advance, and combine these at a construction site to construct a prefab building It is a thing. Further, in such a unit construction method, in order to accommodate the prefabricated building within the oblique line restriction on the north side at the construction site, a so-called trapezoidal unit is arranged in the oblique line restriction corresponding portion or the like.

Here, as a so-called trapezoidal unit,
There are a rectangular parallelepiped unit in which an inclined portion is formed on a part of its upper surface, a rectangular parallelepiped unit whose entire upper surface is inclined, and a rectangular parallelepiped unit in which a step is formed.

For example, a trapezoidal unit 50 shown in FIG. 4 has an inclined portion 51 formed toward one short side surface thereof, and has a ceiling panel 52, a floor panel 53, and a pair of gable panels 54, 55.
Etc. are held in an assembling jig called a total assembling apparatus, and are connected to each other to be manufactured.

In the ceiling panel 52, a pair of beams 56 constituting the ceiling panel 52 are bent downward at a predetermined position, and correspondingly, the pillars 57 of the gable panel 54 have a gable panel 55 having a normal length. It is set shorter than the pillar 58. Wife panel 54, 55
Are substantially frame-shaped, and beams 59 are bridged between the columns 57 and 58 so that the floor panels 53 are arranged so that the lower end surfaces of the columns 57 and 58 have the same height position. It is connected.

By the way, the building units manufactured as described above are arranged and stored in a stock yard of a factory. In the stock yard, it is desirable that the building units are stacked one above the other in terms of space efficiency.
At this time, in order to directly support the weight of the upper building unit, it is preferable that the upper end surface of the lower building unit pillar directly abuts on the lower end surface of the upper building unit pillar.

[0007]

However, the trapezoidal unit 50 described above has a problem that it is difficult to store the stacked layers and space efficiency in the stockyard is poor. For example,
When attempting to place the building unit on the trapezoidal unit 50 described above, the pillar 57 of the trapezoidal unit 50 is shorter than the pillar 58 of the normal length, and the height positions of the lower end surfaces of the pillars are the same. The upper end surface cannot contact the lower end surface of the pillar of the building unit.

Therefore, a part of the weight of the upper building unit is supported by the convex bending portion of the ceiling panel 52 of the trapezoidal unit 50, and as a result, the beam 56 of the ceiling panel 52 is bent or deformed or damaged. Problems such as reaching will occur. Therefore, it is difficult to stack and store the trapezoidal unit 50 as it is.

Further, in manufacturing the trapezoidal unit 50, there is a problem that the production efficiency in the factory is low.
That is, a conventional assembly device holds the upper and lower ends of columns on both sides of a normally-sized gable panel. However, since the gable panel 54 of the trapezoidal unit 50 has a smaller vertical dimension than the gable panel 55, the total assembly device for a normal building unit cannot be used as it is. For this reason, a total assembly device dedicated to the wife panel 54 is separately required, and the factory equipment becomes large-scale.

The above-mentioned problems are caused by the trapezoidal unit 50 in which the inclined portion 51 is formed toward the one short side surface described above.
In addition to the above, a trapezoidal unit in which the entire upper surface of the rectangular parallelepiped unit is inclined, a trapezoidal unit in which a step is formed on the upper surface of the rectangular parallelepiped unit, and the like similarly occur.

An object of the present invention is to provide a method of manufacturing a building unit which can improve space efficiency in a stockyard and production efficiency in a factory.

[0012]

SUMMARY OF THE INVENTION The present invention is a method of handling a building unit having a pillar whose upper end is lower than the maximum height portion, and when handling, up to the upper end of the maximum height portion at the upper end of the pillar. It is characterized in that an extension member that extends is attached.

Here, the handling includes a manufacturing process of building units such as a trapezoidal unit and storage in a stockyard. As the extension member, an adapter type member for filling the difference in length between the columns can be used, and it may be attached to the short column by an appropriate means such as bolting.

[0014]

In the present invention as described above, since the extension member extends to the maximum height of the building unit, even in a column where the weight of another building unit placed on the building unit is shorter than usual in the stockyard. You will be able to support it. In addition, since a column shorter than usual can be made the same length as a regular column, it becomes possible to hold a gable panel whose vertical dimension is smaller than usual when manufacturing it in a factory with an ordinary total assembly device. To be achieved.

A hanging bolt nut 18 that can be screwed is provided.
The hanging bolt nut 18 is also provided on the upper end surface of another column (not shown) having a normal length.

In the factory, pillars 57 and beams shorter than usual
59 and 59 are combined to manufacture a gable panel 54 having a substantially frame shape, and the extension member 11 is attached to the attachment portion 10 of each pillar 57. And
The trapezoidal unit 50 is manufactured by holding the gable panel 54 by a general assembly device for the gable panel and interconnecting it with a ceiling panel, a floor panel (both not shown) and the like.

The trapezoidal unit 50 is an extension member even after manufacturing is completed.
It is transported to the stockyard with the 11 installed, and stacked with other building units. As shown in FIG.
The trapezoidal unit 50, which is the upper building unit, is a crane
A wire (20) extending from (19) is suspended by being connected to a suspension bolt (17) and placed on a lower trapezoidal unit placed on the stockyard. At this time, the upper trapezoidal unit
The 50 is placed so that the lower end surfaces of the pillars 57 and 58 are in contact with the pillar 58 of the lower trapezoidal unit 50 and the upper end surface of the extension member 10, so that its own weight is applied to the ceiling panel of the lower trapezoidal unit 50. Does not work.

According to the present embodiment as described above, since another trapezoidal unit 50 can be placed on the top of the trapezoidal unit 50,
Space efficiency in the stockyard can be improved.

Further, the upper and lower dimensions of the end panel 54 are the extension members.
Since 11 can be attached to the pillar 57 to be the same as the normal gable panel 55, the normal total assembly device can be used, and the production efficiency in the factory that manufactures the trapezoidal unit 50 can be improved.

Further, when the trapezoidal unit 50 is suspended by the crane 19, the crane 19 and the suspension bolts 17 can be equally spaced, so that the suspension balance of the trapezoidal unit 50 can be improved during the work. it can.

Further, since the extension member 11 is attached to the attachment portion 10 by the fixing bolt 13, the attachment / detachment work thereof is facilitated and the extension member 11 can be reused for another trapezoidal unit 50 after use.

The extension member 11 has a positioning pin 15
Is provided, the attachment to the attachment portion 10 is facilitated, and when the extension member 11 is attached to the attachment portion 10, the extension member 11 does not rotate about the axis of the column 57.
