Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a unit type building formed by connecting a plurality of box-shaped building units, and a corner reinforcing material for a unit type building.
[0002]
[Background]
Conventionally, a unit type building constructed by connecting a plurality of box-shaped building units manufactured in a factory at a construction site has been used.
As a building unit forming this unit type building, one having a box-shaped frame in which upper and lower ends of pillars at four corners are connected by a ceiling beam and a floor beam is generally used. The frame has a ceiling surface material supported by the ceiling beam, an interior material such as a floor surface material supported by the floor beam and a partition wall for partitioning the room, and an exterior material such as an outer wall made of lightweight cellular concrete. It is assembled with.
According to such a unit-type building, after the building unit is manufactured by performing the installation work of the interior material and the outer wall material on the box-shaped frame in the factory, these building units are simply transported to the site and connected. Since the building is completed, the work on the construction site is greatly reduced, and the construction work can be completed in a short period of time.
[0003]
By the way, for the connection between building units, for example, a flat plate-like connecting member (hereinafter referred to as a shear plate) is used (see JP-A-7-180228). According to Japanese Patent Laid-Open No. 7-180228, the shear plate is interposed between corner portions of building units adjacent in the vertical direction and the horizontal direction, and connects these building units to each other.
[0004]
[Problems to be solved by the invention]
On the other hand, when a horizontal force acts on the unit type building, the building unit resists this horizontal force with the frame. That is, each pillar of the building unit bears a horizontal force and is elastically deformed.
However, when an excessive horizontal force is applied due to an earthquake or the like, the pillars of the building unit could not bear the horizontal force, and there was a possibility of plastic deformation exceeding the range of elastic deformation. Further, even within the range of elastic deformation, there is a possibility that the construction material or the like inside the building unit may be damaged due to large deformation.
[0005]
An object of the present invention is to provide a unit type building and a corner reinforcing material for a unit type building provided with a corner reinforcing material capable of improving rigidity against a horizontal force while connecting corner portions of the building unit.
