Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building hardware, a building structure, and a method of suspending a building unit.

[0002]

2. Description of the Related Art After a building unit is produced in a factory,
It is transported to the construction site and installed. During installation at this building site, the building units are lifted by cranes and installed on foundations or lower building units.

In the prior art, as a method of suspending a building unit, as described in Japanese Patent Publication No. 59-50835, a frame fitting for locking a suspending fitting at an upper portion between a pair of adjacent vertical frames at four corners of the building unit is used. It has been proposed that the frame metal fitting is supported by pins which are passed between both vertical frames, and a hanging metal fitting is attached to the frame metal fitting and lifted.

[0004]

However, the prior art has the following problems. The frame fitting to which the hanging fitting is attached is used only for the 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] The entire frame fitting to which the hanging fitting is attached is
A pair of vertical frames including the frame fittings, which are accommodated between a pair of vertical frames and supported by pins that are passed across both vertical frames, and the entire frame fitting has a constant wide width. Occupies a considerable width in the wall, which limits the width of the opening that can be provided in the wall.

[0006] In a building, when the main body of the building is joined to the upper and lower structures, the joints are compressed at their own weight, by snow, etc., and tensile by wind, seismic force, etc., while maintaining a compact structure. It is necessary to ensure that the load can be transmitted.

An object of the present invention is to make a joint structure of a building such as a building unit compact.

Another object of the present invention is to realize a method of suspending a building unit without reducing the cost efficiency.

[0009]

According to the first aspect of the present invention, there is provided a building hardware provided at an end of a pillar, wherein the metal fitting is inserted into a slit provided in a longitudinal direction of the pillar body, and the slit of the pillar body is provided. A mounting plate having a pin hole into which a connecting pin inserted into a pin insertion hole provided to intersect with a mounting plate, and integrally connected to an end of the mounting plate, can be installed at an end of the pillar body. And a joined body.

According to a second aspect of the present invention, there is provided an architectural structure of a building having the building hardware according to the first aspect having columns provided at an upper end portion and a lower end portion of a column main body. , The joint of the building hardware provided at the lower end of the pillar body is tied to the lower structure, and the joint of the building hardware provided at the upper end of the pillar body is tied to the upper structure. It is.

[0013] According to a third aspect of the present invention, the joined structure of the building hardware according to the first aspect is set so as to be sandwiched between pillar members at an end of the pillar body.

According to a fourth aspect of the present invention, there is provided a method of suspending a building unit having the architectural hardware according to the first aspect, wherein the joint of the architectural hardware provided at the upper end of the pillar body. It is designed to attach a hanging bracket to the hoist and lift it.

According to the first aspect of the present invention,
Has the effect of The metal joint is installed at the upper end or lower end of the pillar body of the pillar, and the mounting plate is inserted into the slit of the pillar body and pin-coupled. Therefore, the column main body can be narrowed (compact) only by sandwiching the relatively thin mounting plate, and the opening width of a window, an entrance and the like provided adjacent to the column main body in the wall can be widened.

The compressive load and the tensile load acting on the building are:
It is reliably transmitted through the connecting pin between the mounting plate of the hardware and the pillar body. In addition, the compressive load is more reliably transmitted through a wide abutment surface between the joined body and the end of the column main body because the joined body of metal is installed at the end of the column main body.

According to the second aspect of the present invention,
Has the effect of Since the hardware is provided at each of the upper end and the lower end of the pillar main body, the joint structure of the building can be immediately made more compact by using these pillars.

In the above, the metal structure provided at the lower end of the column main body can make the joint structure with the lower structure such as the floor structure compact. In addition, the metal structure provided at the upper end of the pillar main body can make the joint structure with the upper structure such as the upper-floor building unit compact.

According to the third aspect of the present invention, the following operations are provided. At the end of the pillar body where the metal joint was installed, pillar materials were left on both sides of the pillar body. Therefore, the upper frame of the wall can be directly fixed to the pillars on both sides of the joined body by nailing at the upper end of the pillar body.
Further, the lower frame of the wall can be directly fixed to the pillar members on both sides of the pillar body by nailing at the lower end of the pillar body. Thereby, when the metal of the present invention is incorporated in a pillar constituting a wall panel made of a pillar and a frame, the pillar and the frame can be joined by the frame so that the frame covers the end face of the pillar. Can be. In addition, the hardware is pin-connected by inserting the mounting plate into the slit of the pillar body, and the pillar members on both sides of the joined body need not be thin, so that the narrowing (compact) of the pillar body is not hindered.

According to the present invention, the following effects are obtained. The hardware to which the hanging metal fittings are attached is used for lifting work, and then used for joining with an upper structure such as an upper-floor building unit. Therefore, the hanging fitting can be attached without lowering the cost efficiency of the building unit.
