Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hardware for building, a building structure, and a method for hanging a building unit.
[0002]
[Prior art]
After the building unit is produced at the factory, it is transported to the building site and installed. At the time of installation at the construction site, the building unit is lifted by a crane and installed on the foundation or lower floor building unit.
[0003]
In the prior art, as a method of hanging a building unit, as described in Japanese Examined Patent Publication No. 59-50835, a frame bracket for locking a hanging bracket is placed in the upper part between a pair of adjacent vertical frames at the four corners of the building unit. It has been proposed that a frame metal fitting is supported by pins extending between both vertical frames, and a hanging metal fitting is attached to the frame metal fitting and lifted.
[0004]
[Problems to be solved by the invention]
However, the prior art has the following problems.
{Circle around (1)} The frame bracket to which the hanging bracket is attached is used only for lifting work, and is stored between a pair of vertical frames and cannot be collected after the lifting work, so that the cost efficiency is low.
[0005]
(2) The entire frame bracket to which the hanging bracket is attached is supported by a pin that is placed between a pair of vertical frames and passed between both vertical frames. Therefore, the pair of vertical frames including the frame metal occupies a considerable width in the wall, and limits the widening of the opening width that can be provided in the wall.

Accordingly, the column body 27 can be narrowed (compact) only by sandwiching the relatively thin mounting plates 31 and 41, and the opening width of windows, doorways, etc. provided adjacent to the column body 27 in the wall can be reduced. Can be widened.
[0038]
(2) The compressive load and tensile load acting on the building unit 10 are reliably transmitted through the connecting pins 33 and 43 between the mounting plates 31 and 41 of the hardware 30 and 40 and the column main body 27. Further, the compressive load is such that the joined bodies 32, 42 of the hardware 30, 40 are installed at the end of the column main body 27, so that a wide abutting surface between the joined bodies 32, 42 and the end of the column main body 27 is formed. More reliably.
[0039]
(3) Since the hardware 30 and 40 are provided on the upper end and the lower end of the column main body 27 of the column 23, the connection structure of the building unit 10 can be immediately established by using the column 23 as described in the items (1) and (2). Can be made more compact.
[0040]
{Circle around (4)} In the above {circle around (3)}, the joint structure with the lower structure such as the floor panel 11 can be made compact by the lower metal fitting 40 provided at the lower end of the column main body 27. Moreover, the upper metal fitting 30 provided in the upper end part of the column main body 27 can make a joining structure with upper structures, such as the upper floor building unit 10B, compact.
[0041]
{Circle around (5)} The upper hardware 30 to which the hanging metal fitting 60 is attached is used for lifting work, and is then used for joining with an upper structure such as the upper floor building unit 10B. Therefore, the hanging bracket 60 can be attached without reducing the cost efficiency of the building unit 10.
[0042]
Second Embodiment (FIG. 9)
