1.Field of the Invention
The present invention relates to reinforcing hardware for
wooden housing that connects and reinforces beams, such as a
vertical girder and a horizontal girder, of a wooden housing.
2. Description of the Related Art
Conventionally, as reinforcing hardware for wooden
housing that connects and reinforces a vertical girder and a
horizontal girder, hardware commonly referred to as a strap bolt
is known. In this reinforcing hardware, a bolt is fixedly
attached to a metal strap. A strap bolt such as this has a
disadvantage in that, even when retightening or the like is to
be performed after construction of the housing, retightening
or the like cannotbe performedbecause the bolt cannotbe rotated
from the strap bolt side and a nut is positioned on an outer
side (within an outer wall).
In addition, when a housing is to be demolished, because
the vertical girder and the horizontal girder are connected by
the strap bolt, the coupling of the vertical girder and the
horizontal girder cannot be easily released. A joining portion
of pieces of lumber cannot be disassembled unless the strap bolt
or the like is destroyed.
Regarding hardware in which the bolt is not fixed to the strap, for example, "a strap characterized by including: a strap main body in which a bolt is detachably or fixedly attached to one end portion; a bolt insertion hole in which a notched portion is formed in an opposing section formed in a section near an other end portion of the strap main body; and a bolt that bites into lumber, such as a column, in a rotating manner by being driven into a bolt main body portion in a section near a head portion inserted into the bolt insertion hole and has a biting piece that is formed in a section corresponding to the notched portion of the bolt insertion hole" (Patent Literature 1) is known.
However, regarding such a strap as well, because the bolt
itself cannot be rotated and the nut is positioned on the outer
side (within the outer wall), there is a disadvantage in that
retightening or the like cannot be performed.
Here, when a bolt in which the biting piece is not provided
is used, the bolt can be rotated. However, the nut may spin.
Retightening cannot be reliably performed. During demolition
of a housing as well, disassembly may not be able to be performed
as a result of the nut spinning, and the bolt or the like may
be required to be destroyed.

Publication No. 2000-320013
In light of conventional disadvantages such as those
described above, a need of the present invention is to provide
reinforcing hardware for wooden housing that is able to be easily
and reliably retightened, and easily disassembled during
demolition.
It is an object of the present invention to meet this need
or to substantially overcome, or at least ameliorate, one or more
disadvantages of existing arrangements.
According to an aspect of the present invention, there is
provided, reinforcing hardware for wooden housing configured by:
a strap nut that has a screw portion and a strap portion; a bolt
that has a first screw portion that is screwed into the screw
portion of the strap nut and a second screw portion on a side
opposite the first screw portion; and a nut member that screws
onto the second screw portion. A tool engaging portion into which
a tip end portion of a tool is able to be inserted and by which
the bolt is able to be rotated is formed on at least an end surface
on the first screw portion side, and the second screw portion is
formed as a screw that turns in a direction opposite the first
screw portion.
As is clear from the description above, the present
invention achieves the effects listed below:
(1) According to a first aspect of the invention, the tool
engaging portion is formed on the end surface on the first screw
portion side. Therefore, even after a housing is constructed, a
tip end portion of a screwdriver or the like can be engaged with
the tool engaging portion, and retightening or the like can be
performed.
(2) The strap nut, the bolt, and the nut member can be
separated. Therefore, during demolition, the strap nut and the
bolt can each be separated by the bolt being rotated.
Consequently, coupling of pieces of lumber can be easily
released. The disassembled materials can be reused.
(3) According to second to fourth aspects of the invention
as well, effects similar to (1) and (2), described above, can be
achieved. In addition, the second screw portion can be screwed
to the nut member simply by the bolt being pressed into the nut
member.
Furthermore, the strap nut and the bolt can each be more
easily separated during demolition.
(4) Moreover, because the washer member is provided, the
nut member can be easily fixed to lumber and the like, and used.

The present invention will hereinafter be described in
detail based on embodiments for carrying out the present
invention shown in the drawings.
According to a first embodiment for carrying out the present invention shown in FIG. 1 to FIG. 6, reference number
1 represents reinforcing hardware for wooden housing (referred
to, hereafter, as "reinforcing hardware") that connects and
reinforces beams, such as a vertical girder S and a horizontal
girder C) of a wooden housing.
As shown in FIG. 1, the reinforcing hardware is configured
by a strap nut 4, a bolt 7, and a nut member 8. The strap nut
4 has a screw portion 2 (female screw) and a strap portion 3.
The bolt 7 has a first screw portion 5 (male screw) and a second
screw portion 6 (male screw). The first screw portion 5 is
screwed into the screw portion 2 of the strap nut 4. The second
screw portion 6 is formed on an end portion of the bolt 7 on
the side opposite the first screw portion 5. The nut member 8
screws onto the second screw portion 6.
The strap nut 4 is configured by the strap portion 3 and
the screw portion 2. The strap portion 3 is rectangular. Anail
hole 9 into which a nail is inserted and a bolt through-hole
10 are formed in the strap portion 3. The screw portion 2 is
screwed to the first screw portion 5. For example, as shown in
FIG. 2, the screw portion 2 is fixed to a surface of the strap
portion 3. According to the present embodiment, the screw
portion 2 is fixed to a substantially center portion of the
surface of the strap portion 3 by welding. A screw hole of the
screw portion 2 is formed such as to be screwed to the first
screw portion 5.
In the bolt 7, the first screw portion 5 is formed near
one end portion. Meanwhile, the second screw portion 6 is formed
near the other end portion on the side opposite the first screw
portion 5.
In addition, a tool engaging portion 11 (having a minus
shape, a plus shape, or the like) that engages with a tool, such
as a screwdriver or an Allen wrench, is formed on an end surface
of the bolt 7 on the first screw portion 5 side. According to
the present embodiment, a substantially cross-shaped tool
engaging portion 11 is formed such that a tip portion of a
Phillips head screwdriver engages therewith.
The tool engaging portion 11 may be formed on only the end
surface on the first screw portion 5 side. Alternatively, the
tool engaging portion 11 may be formed on the end surface on
the first screw portion 5 side and the end surface on the second
screw portion 6 side.
According to the present embodiment, the first screw
portion 5 of the bolt is formed to be a left-handed screw. The
second screw portion 6 is formed to be a right-handed screw.
As a result of the screw portions 5 and 6 being formed in this
manner, retightening can be performedby the bolt 7 being rotated
in a single direction.
Here, all that is required is that the first screw portion
5 and the second screw portion 6 be screws that are turned in
opposite directions. Therefore, the first screw portion 5 may be the right-handed screw and the second screw portion 6 may be the left-handed screw.
The nut member 8 is configured by a nut main body 13, a
plurality of nut segments 14, an urging means 15, a holding means
16, and a washer member 17. The nut main body 13 has a single
or a plurality of nut segment housing portions 12. According
to the present embodiment, the nut main body 13 has three nut
segment housing portions 12. The nut segment 14 is housed in
the nut segment housing portion 12. According to the present
embodiment, three nut segments 14 are respectively housed in
the three nut segment housing portions 12. The urging means 15
is provided above the nut segments 14 and urges the nut segments
14 in a direction towards a bottom surface of the nut main body
13. The holdingmeans16holds the nut segments14 and the urging
means 15 (such as an urging spring) inside the nut main body
13. The washer member 17 is provided in a lower end portion of
the nut main body 13.
The nut segment 14 of the nut member 8 is formed such as
to be screwed onto the second screw portion 6.
According to the present embodiment, in the holdingmember
16, a washer is locked by an upper end portion of the nut main
body 13 being bend inward by crimping. The holding means 16
thereby holds the nut segments 14 and the urging mean 15 inside
the nut main body 13. For example, the holding means 16 may be
such that a screw is formed on an outer peripheral surface near the upper portion of the nut main body 13. A cap nut-like cover body is screwed onto the screw, and the nut segments 14 and the urging means 15 are thereby held inside the nut main body 13.
According to the present embodiment, the washer member 17
is rotatably provided in the nut main body 13. A plurality of
prongs 18 are formed on a bottom surface of the washer member
17. The nut member 8 is attached to lumber by the prongs 18.
A nut in which publicly known nut segments are used can
be used as the nut member 8.
When retightening is performed using the reinforcing
hardware 1 of the present invention, as shown in FIG. 6, the
tipendportion ofa screwdriveris engagedwith the toolengaging
portion 11 and the bolt 7 is rotated. Because the first screw
portion 5 and the second screw portion 6 are formed as screws
that are turned in opposite directions, tightening of the screw
portion 2 and the nut member 8 can be simultaneously performed.
When demolition is performed, as a result of the bolt 7
being rotated in the direction opposite the direction when
retightening, on the nut member 8 side, the bolt 7 attempts to
move towards the strap nut 4 side (inward) as a result of the
rotation of the bolt 7. However, the strap nut 4 side also
attempts to move towards the nut member 8 side (inward).
Therefore, the screw portion 2 and the nut member 8 receive force
in an axial direction. As a result, the nut segments 14 are
pressed by this force and move outward against the urging force from the urging means 15. An inner diameter of the nut member
8 therebyincreases. As aresult, the first screwportion5moves
in a direction (towards the nut member 8 side detaching from
the screw portion 2 of the strap nut 4. The reinforcing hardware
1 can be thereby be disassembled.
[Other embodiments for carrying out the invention]
Next, other embodiments for carrying out the present
invention, shown in FIG. 7 to FIG. 10, will be described.
Regarding the descriptions of the other embodiments for carrying
out the present invention, constituent sections that are
identical to those according to the above-described first
embodiment for carrying out the present invention are given the
same reference numbers. Redundant descriptions are omitted.
Asecondembodiment for carrying out the presentinvention,
shown in FIG. 7 to FIG. 9, mainly differs from the first
embodiment for carrying out the presentinventionin that a strap
nut 4A and a nut member 8A are used. The strap nut 4A is
configured by a strap portion 3A that has a nut inserting portion
19 and a nut 2A that is inserted into the nut inserting portion
19 and serves as a screw portion 2A. In the nut member 8A, a
washer member 17A is fixed near a bottom surface of the nut main
body 13. In addition, a hexagonal hole-shaped tool engaging
portion 11A is formed on the end surface of the first screw
portion 5 of the bolt 7. A reinforcing hardware 1A such as this
can also achieve working effects similar to those according to the first embodiment for carrying out the present invention.
Here, the washer member 17A according to the present
embodiment does nothave tabs. The washermember17Ais provided
with plurality of screw holes 20 into which countersunk screws
can be inserted and is attached to lumber by the countersunk
screws.
A third embodiment for carrying out the present invention
shown in FIG. 10 mainly differs from the above-described first
embodiment for carrying out the present invention in that a
typical nut that does not include nut segments is used as a nut
member 8B. A reinforcing hardware 1B such as this can also
achieve working effects similar to those according to the first
embodiment for carrying out the present invention.
According to the present embodiment, because the typical
nut is used as the nut member 8B, when the bolt 7 is rotated
during demolition, the nut member 8B receives force in the axial
direction and the nut member 8B itself moves outward. The bolt
7 detaches from the strap nut 4 and disassembly can thereby be
performed.
According to the embodiments of the present invention, an
embodiment in which three nut segments are used as the nut
segments of the nut member is described. However, all that is
required is that a plurality of nut segments be provided. For
example, two, six, or eight nut segments may be used.
The present invention is used in an industry for
manufacturing reinforcing hardware for wooden housing, an
industry for constructing wooden housing, and an industry for
construction using heavy- and light-weight steel frames.
