EARTHQUAKE ANT REINFORCEMENT APPARATUS,‘
EARTHQUAKE RESISTANT BUILDING, AND AN EARTHQUAKE
RESISTANT REINFORCING METHOD
CROSS—REFERENCE TO RELATED APPLICATIONS
The disclosure of Japanese Patent Application No. 2013-
157441 filed on July 30, 2013 including the specification,
drawings, and abstract is incorporated herein by reference in
its entirety.
BACKGROUND OF THE INVENTION
Field of the Invention
The t invention relates to earthquake resistant
reinforcement of a building having a frame structure and it
particularly s to an earthquake resistant reinforcement
for a building of relatively low story.
Description of the Related Art
Japan geographically situates in uake prone areas
and frequently suffered from disastrous earthquakes
historically in various districts of the country. Particularly,
it has been said that the t age is going to enter the
period of crustal movement and the possibility of seismic
disaster has been increased.
NUmber of existent buildings in Japan amounts to
,000 or more including many residential buildings not
addressing to earthquake resistance or those aged residences
likely to suffer from damages.
Further, most of such residences have wooden framework
structures, and are not ient for earthquake resistance
and, accordingly, require earthquake resistant reinforcement.
r, actual progress of adopting the earthquake
resistant reinforcement is very slow and, while there are
,000,000 or more residences requiring such earthquake
resistant rcement in Japan, countermeasures or
have not been advanced at present.
SUMMARY OF THE INVENTION
In view of the situations described above, several
techniques have been developed for promoting adoption of the
earthquake resistant reinforcement.
For example, JP—A No. 2010—275473 provides an anti-
seismic device having an anti—seismic element of a specified
shape. The device can absorb a seismic force acting on the
structural frame of a building by plastic bending deformation
of the anti—seismic element, thereby preventing deformation of
the building and providing earthquake resistant reinforcement.
r, installation of the anti—seismic device to
existent building requires relatively large—scaled
construction work, for example, partial detachment of ceiling
or floor to give a significant burden on inhabitants.
Further, for avoiding the large-scaled renovation as
described above, a technique as disclosed in JP—A No. 2013-
19233 is also proposed. This is a technique of performing
uake resistant reinforcement by simple and convenient
construction work of merely removing existent outer walls from
below the ceiling to above the floor and installing an
earthquake resistant wall. However, even such a simple and
convenient construction work imposes a large burden on aged
buildings to bring about a m that there is a limit of
ensuring qualified earthquake resistant strength.
The present invention has been accomplished in view of
the problems described above and s to provide an
uake resistant rcement apparatus of high
earthquake resistant strength, which can be attached simply
and iently without imposing significant burdens on
inhabitants even to buildings constructed before the year of
1980 in which the new revised earthquake resistant standards
were ished, since an earthquake resistant wall plane is
attached newly by way of a horizontal tion beam that
also serves as an attaching member for an earthquake resistant
wall from the outside of the building.
Alternatively, it is an object of the invention to at
least provide the public with a useful choice.
For solving the problems described above, the present
invention provides in one aspect, an earthquake resistant
reinforcement apparatus of a structure comprising an antiseismic
device for absorbing a c energy, an attaching
member for attaching the anti-seismic device to the outside of
a ng, and a horizontal supporting member for supporting
the anti-seismic device substantially horizontally.
Further, for solving the problem described above, the present
invention provides in another aspect, an earthquake resistant
building comprising an anti-seismic device for absorbing a
seismic energy, an attaching member for attaching the antiseismic
device to the outside of the ng, and a horizontal
supporting member for ting the anti-seismic device
substantially horizontally.
Further, for solving the problem described above, the
present invention es in another aspect
An earthquake resistance reinforcing method using an
earthquake resistant rcing apparatus of a ure
including an anti-seismic device for absorbing a seismic
energy, an ing member for attaching the anti-seismic
device to the outside of a ng, and a horizontal
supporting member for supporting the anti-seismic device
substantially horizontally, in which the method includes:
forming a recess for attaching the attaching member to
the outer wall of the building,
attaching the attaching member to a portion where the
recess is formed for attaching the attaching member, and
supporting the attaching member to a portion exposed
through the recess, and
supporting the anti-seismic device by the attaching
member and the ntal supporting member.
Since the externally attached earthquake resistant wall
plane of the invention can be simply attached by a required
number in parallel with the wall surface of an existent
building that requires reinforcement outer wall e at a
some clearance from the outer wall, this provides an advantage
capable of economizing the space for installation.
According to the present invention, earthquake resistant
reinforcement of the ng can be med simply and
iently simultaneously with th reinforcement of an
existent ng. r, according to the invention, since
the earthquake reinforcement can be provided by attachment of
a bearing bracket and a horizontal connection beam and the
uake resistant wall plane only by the construction work
from the out side, significant burden on the inhabitants can
be avoided.
Specifically, the externally added earthquake resistant
wall structure of the invention has the following advantages.
(1) An earthquake resistant reinforcement structure that can
be applied both to wooden and steel structures irrespective of
the kind of the structure of existent buildings.
(2) The earthquake resistant bracket and the earthquake
resistant wall plane can be attached from the outside of the
outer wall by one side work without demolition of the existent
building, and it needs no large place for installation.
(3) As to be described later, installation is extremely
simple and convenient to mitigate inhabitants' troubles.
(4) Since the earthquake resistant wall plane is installed
by way of a bearing bracket directly on one side to a girder
of an existent building, a seismic force is absorbed ly
and high performance can be expected.
(5) The earthquake resistant reinforcement structure has no
ature dependence and the performance does not change
also at the outdoor.
(6) This has a tough structure capable of withstanding
repetitive after—shocks.
(7) The reinforcement structure is made of inexpensive metal
materials of a simple structure and has improved workability.
Further, since the construction work can be simplified further
compared with the existent techniques, earthquake resistant
reinforcement can be ed with no large—scaled
construction work even for aged buildings.

Preferred Embodiments
8 [followed by page 8a]
Fig. 1 is a perspective view illustrating the outline of
an earthquake ant reinforcing structure of the present
invention.
According to the invention, an earthquake resistant wall
plane 11 (earthquake resistant wall plane 11 as an anti-
[followed by page 9]
8a [followed by page 9]
seismic ) having an anti—seismic function is attached to
the outside of an outer wall of an existent building 1,
thereby providing earthquake resistant reinforcement to the
existent building.
The t invention can provide earthquake resistant
reinforcement both to buildings of a wooden structure and
ngs of a steel structure (non—wooden structure), and
description is to be made herein with reference to an example
of a building having the steel structure. r, the
invention provides a structure that can be ed also for
earthquake resistant reinforcement of a new building. Since
the invention intends to rce mainly the existent
building, the following description is to be made to an
embodiment of the existent ng. "Building" includes
herein not only existent ngs but sometimes also
buildings to be-built newly. Further, in the present
specification, "earthquake resistant wall plane" is an
abbreviation of "bearing and earthquake resistant wall plane"
and it may also include, without restriction, a bearing wall
plane not accompanied by the anti—seismic function.
The existent building 1 comprises a footing 2, a girder
3, and main columns 4 (main column 4a and mail column 4b) of
the building 1. The structure of the existent building 1
r 3 and main column 4) may be made of a wooden material
or a non—wooden material (such as a steel frame)
The earthquake resistant wall plane 11 comprises support
columns 12 (support column 12a and support column 12b), and
steel pipe braces 13 (steel pipe brace 13a to steel pipe brace
13d) as connection members.
The support column 12a has a fixing metal 15a at an
upper stage of an inner lateral side, a fixing metal 15c at a
lower stage of the inner lateral side, and an anti—seismic
element 14a at a middle stage of the inner lateral side.
The support column 12b has a fixing metal 15b at the
upper stage of the inner lateral side, a fixing metal 15d at
the lower stage of the inner lateral side, and an anti-seismic
element 14b at the middle stage of the inner lateral surface.
The anti—seismic t 14 is an element of a
ntially'EZ—shaped configuration (Fig. 2A and Fig. 2B)
described, for example, in JP—A 2009—275473 which absorbs a
seismic force that may act on the ng by plastic bending
deformation of the anti-seismic element. In a bearing wall
plane having no anti—seismic function, a fixing metal of the
same type is applied instead of the anti—seismic element.
The support column 12a and the support column 12b are
connected by two upper and lower pairs of steel pipe braces 13,
each pair crossing diagonally. That is, an upper end of the
steel pipe brace 13a is fixed to the fixing metal 15a and the
lower end of the steel pipe brace 13b is fixed to the anti—
seismic t 14b. Further, the upper end of the steel pipe
brace 13b is fixed to the fixing metal 15b and the lower end
of the steel pipe brace 13b is fixed to the anti—seismic
element 14a. Further, the upper end of the steel pipe brace
13c is fixed to the anti—seismic element 14a and the lower end
of the steel pipe brace 13c is fixed to the fixing metal 15d.
Further, the upper end of the steel pipe brace 13d is fixed to
the anti—seismic element 14b and the lower end of the steel
pipe brace 13d is fixed to the fixing metal 15c. Thus, the
support column 12a and the support column 12b are connected
firmly by using a high tension bolt to thereby constitute an
earthquake resistant wall plane 11.
The outer wall 16 of the existent ng 1 is made of
various kinds of materials and has various configurations and
sizes. The earthquake resistant wall plane 11 constituted as
bed above is provided at a some clearance relative to
the outside of the outer wall (to be described specifically
later).
A column head 17 of the uake resistant wall plane
11 is supported by a g bracket 21 as an attaching member
and a horizontal connection beam 22 as a horizontal supporting
element, and a column leg 18 of the earthquake resistant wall
plane 11 is supported by a reinforcing footing 23 and attached
to the existent building 1.
At first, a method of fixing the column head 17 is to be
described. For fixing the column head 17, the outer wall 16 is
recessed for a necessary range at each portion to which the
bearing bracket 21 is attached, to thereby expose the girder
of the building as an existent structure, and an upper end
disposing member is disposed on the lateral side of the girder
3. In the upper end disposing member, the bearing bracket 21
is screw-fixed to the girder 3 on one side, and then a
horizontal connection beam 22 is ntally disposed along
the girder 3 to the top end of the arm of the bearing bracket
The g bracket 21 has a gular bottom plate 27
and two opposing trigonal arm plates 26. A connection hole is
formed at a cross section of the arm plate 26 on the side of
the girder 3 and the two arm plates 26 are tightly connected
by bolts and nuts or one—sided bolts such that the two arm
plates 26 put the main column 12 between them. FUrther, the
bottom of the arm plate 26 and the upper surface of the bottom
plate 27 are welded. Further, the connection hole is formed in
the bottom plate 27 for connection with the horizontal
tion beam 22.
The horizontal connection beam 22 is made of an L—shaped
steel material and attached to the bearing t 21 such
that the cross n is downwarded. The kind of the steel
material, the direction of the cross section for attachment,
and the length of the steel material can be selected
ally. Connection holes are formed each at a
predetermined position of the horizontal connection beam 22,
and the horizontal connection beam 22 and a plurality of
bearing brackets 21 are connected by inserting known
connection s (for example, bolts) through the connection
holes. A member for disposing the column top of the support
column 12 is provided as described above.
Then, a method of fixing a column leg 18 is to be
described. For fixing the column leg 18, a column leg
disposing member such as a reinforcing footing 23 formed by
subsequently piling te along an nt continuous
footing 2 is used, for example, in a wet construction method.
The reinforcing footing is provided so as to extend partially
or entirely along the continuous footing 2 of the existent
building. Anchor bolts 25 for fixing the column legs are
provided to predetermined positions at the upper surface of
the reinforcing footing 23, and the column legs 18 are fixed
by the anchor bolts 25.
Each of the column legs 18 of the support columns 12 is
fixed in a wet construction , as illustrated in Fig. 3A,
by using an anchor bolt 44 buried in a rced concrete
footing (reinforcing footing 23) formed by piling concrete
along the existent continuous footing (footing 2) and a hold
down metal 41 welded or screw-fixed to the column leg 18 of
the support column 12 together. Thus, the support column 12 is
firmly fixed by the footing 2.
As illustrated in Fig. 3B. The column leg may also be
fixed, in a dry construction method, by a hold down metal 41
welded or screw-fixed to the column leg by using a l
member 43 fixed to the lateral side of the footing 2 instead
of the reinforcing footing 23.
Fig. 4 is a lateral longitudinal cross sectional view of
an existent building of a light—gauge steel structure and an
earthquake resistant wall plane 11.
The earthquake resistant wall plane 11 is ably
attached such that a some clearance 31 is formed relative to
the outer wall 16 of the existent building 1. That is, a
clearance of about 100 mm is formed between the center of the
support column 12 of the earthquake resistant wall plane 11
and the center of the outer wall 16 of the existent building 1
such that the earthquake resistant wall plane 11 and the
existent building 1 are not in contact to each other upon
undergoing seismic vibrations. This can prevent interference
between the earthquake ant wall plane 11 and the
nt building 1 when earthquake occurs, which may
otherwise fracture the ing portion or damage the outer
wall 16. The clearance between them is not restricted to 100
mm but can be selected optionally.
In this embodiment, the g bracket 21 is provided
to a joint between the main column 12 and the girder 3 (Fig.
1). That is, the bearing bracket 21 is provided not in a
continuous stripe configuration along the girder 3 but
provided ise at a position where the main column 12 and
the girder 3 intersect (corresponding to the point of contact
of the horizontal lattice beam).
The bearing bracket 21 is disposed by forming a recess
in the outer wall of the existent building 1. If a strip—like
continuous recess is formed, some or other bearing defects may
be caused to the existent building 1. However, since the
bearing brackets 21 are ed spot—wise, burden on the
nt building 1 can be zed.
Further, since the girder 3 of the nt building and
the horizontal connecting beam 22 are integrated to provide
earthquake ant reinforcement more strongly and the
seismic force acting on the existent building 1 is reliably
transmitted to the earthquake resistant wall plane 11 and
minimize the load of the seismic force on the existent
building.
Further, when a plurality of the bearing brackets 21 are
connected by the horizontal connection beam 22 as illustrated
in Fig. 1, the horizontal connection beam 22 serves as a sort
of a wind resistant horizontal beam. Accordingly, they can
endure the horizontal seismic force acting on the nt
building 1 in ation with the girder 3 for the outer wall
of the existent building 1 and can transmit the acting force
with scarce loss to the externally attached earthquake
resistant wall plane 11. This effect cannot be provided
sufficiently only by using the bearing ts 21 but can be
provided sufficiently only when the bearing t 21 is
combined with the horizontal connected beam 22. The length of
the horizontal connection beam 22 is increased or decreased
depending on the scale of the existent building 1 or the
number of the earthquake resistant wall planes 11, thereby
capable of ning the time for the construction work and
ng the construction cost. Further, provision of the
horizontal connection beam 22 can reinforce the building
itself.
Fig. 5 illustrates another embodiment of the earthquake
resistant structure according to the invention. A bearing
bracket 21 ses a rectangular bottom plate 61, a
rectangular back plate 62, and two opposing trigonal arm
plates 63.
The arm plate 63 and the back plate 62 are bent into a
'U—shaped configuration and welded to the bottom plate 61.
Connection holes for connection with the existent building 1
and the girder 3 are formed in the bottom plate 62.
When the bearing bracket 21 is attached to the girder 3
of the existent building 1, the bearing bracket 21 is tightly
joined to the web of the girder 3 from the outside by a one—
sided bolt irrespective of the position of the main column 4
of the existent building 1.
Further, connection holes are formed in the bottom plate
61 for tightly connecting the lower flange of the girder 3 and
the horizontal connection beam 22.
This embodiment is extremely effective since the
externally added earthquake resistant plane 11 can be
led to an optional position of the existent building 1
(outer wall 16).
Fig. 6 and Fig. 7 illustrate other embodiments of the
earthquake ant structure according to the invention in
which Fig. 6 illustrates an embodiment of attaching a bearing
bracket 21 to an existent building of a wooden frame structure
and Fig. 7 shows an embodiment of attaching a bearing bracket
21 to an existent building of a steel structure.
Fig. 8 rates the bearing bracket 21 of Fig. 6 and
Fig. 7 in details. As illustrated in Fig. 8, the g
bracket 21 comprises a rectangular back plate 71 for
ment to the lateral side facing the outside of the
girder 3 of the existent ng 1, a substantially trigonal
arm plate 72 (arm) attached vertically to the central portion
thereof, and a horizontal vibration stop plate 73 for
horizontally connecting the back plate 71 and the arm plate 72
(horizontal vibration stop member for preventing the arm plate
72 from vibrating in the horizontal ion), and an angle
74 for attaching a horizontal connection beam 22 is welded to
the outside of the horizontal vibration stop plate 73. By
mounting the bearing bracket 21 and the horizontal connection
beam 22 of the structure described above to an existent wooden
building 1, a ntal seismic force can be transmitted
reliably to the externally added earthquake resistant wall
plane 11. Further, provision of the horizontal vibration stop
plate 73 can decrease the number of the g brackets 21 to
be installed.
Then, a method of attaching the bearing bracket 21 to
the existent building 1 is to be described.
At first, for attaching the bearing bracket 21, a
plurality of recesses are formed spot—wise to the outer wall
of the existent ng 1. The recesses are formed only to
the portions of attaching the bearing ts 21 and each of
the recesses is cut out to a size substantially equal with
that of the back surface (attaching portion) of the bearing
bracket 21. By minimizing the recessed portion, g
deficiency of the existent building 1 can be minimized.
