Description

本発明は、地盤沈下による建物の傾斜を防ぐための建物支持装置に関するものである。   The present invention relates to a building support device for preventing the inclination of a building due to ground subsidence.

従来、例えば地震による液状化現象で地盤沈下を生じた場合、家屋やビル等の建物の一部が地盤沈下を生じた空洞に沈下して建物が傾くといった被害を受ける場合がある。このような場合には、例えば沈下した建物の基礎を油圧ジャッキ等によって押し上げるとともに、鋼管等の支柱で支持し、沈下した地盤をコンクリート等によって埋め戻すことにより、建物を元の水平状態に戻す修復工事が行われる（例えば、特許文献１参照）。   Conventionally, when a land subsidence occurs due to a liquefaction phenomenon caused by an earthquake, for example, a part of a building such as a house or a building may sink into a cavity where the land subsidence occurs and the building may be damaged. In such a case, for example, the foundation of the submerged building is pushed up with a hydraulic jack, etc., supported by a column such as a steel pipe, and the subsidence ground is backfilled with concrete, etc., to restore the building to its original horizontal state. Construction is performed (see, for example, Patent Document 1).

特開２０１０−２４８７４４号公報JP 2010-248744 A

しかしながら、地盤沈下により傾いた建物を修復するためには、前述のように油圧ジャッキ等を用いて建物を押し上げるなどの大掛かりな修復工事が必要となるため、修復までに長期間を要するとともに、修復に要する経済的な負担も大きくなる。また、建物を水平状態に修復した場合であっても、一旦大きく傾いた建物は、梁、柱、建具等に歪みが残る場合が多く、完全に元の状態に戻すことは困難であった。   However, in order to repair a building that has been tilted due to land subsidence, large-scale restoration work, such as pushing up the building using a hydraulic jack as described above, is required. The economic burden required for this will also increase. Moreover, even when the building is restored to a horizontal state, a building that has been largely inclined once has many distortions remaining in the beams, columns, fittings, etc., and it has been difficult to completely restore the original state.

本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、地盤沈下が生じた場合でも建物の傾斜を抑制することのできる建物支持装置を提供することにある。   This invention is made | formed in view of the said problem, The place made into the objective is providing the building support apparatus which can suppress the inclination of a building, even when ground subsidence arises.

本発明の建物支持装置は、前記目的を達成するために、上端側によって建物本体を下方から支持する第１の支持部材と、下端側を地盤側に接地された第２の支持部材と、第２の支持部材を第１の支持部材に対して下方に付勢する付勢手段と、第１の支持部材に対する第２の支持部材の上方への移動を規制する移動規制手段とを備えた複数の支持ユニットを建物本体側と地盤側との間の複数箇所に設置し、各支持ユニットを、建物本体に対して地盤沈下により傾斜する耐圧盤上に設置するとともに、第２の支持部材の下端側を自在継ぎ手を介して耐圧盤に揺動自在に連結している。 In order to achieve the above object, the building support apparatus of the present invention includes a first support member that supports the building body from below by an upper end side, a second support member that is grounded at the lower end side to the ground side, A plurality of urging means for urging the two support members downward with respect to the first support member; and a movement restricting means for restricting the upward movement of the second support member relative to the first support member. Are installed at a plurality of locations between the building main body side and the ground side, and each supporting unit is installed on a pressure-resistant panel that is inclined with respect to the building main body due to ground subsidence, and the lower end of the second supporting member The side is swingably connected to a pressure-resistant panel via a universal joint .

これにより、建物の地盤に地盤沈下が生じた場合には、地盤沈下した位置の支持ユニットの第２の支持部材が地盤沈下した分だけ第１の支持部材に対して下方に移動し、伸長した支持ユニットによって建物が下方から支持されることから、地盤沈下による建物の傾斜が抑制される。その際、第２の支持部材は付勢手段によって下方に付勢されていることから、第２の支持部材が地盤沈下に追従するように下方に移動する。また、第２の支持部材は移動規制手段によって反対方向への移動を規制されることから、下方に移動した状態に保持される。更に、各支持ユニットが建物本体側と地盤側の耐圧盤との間に設置され、建物本体に対して耐圧盤が地盤沈下によって傾斜するようになっていることから、一部の支持ユニットの設置位置のみが過度に沈下することがなく、沈下量が各支持ユニットに分散する。 As a result, when the ground subsidence occurs in the ground of the building, the second support member of the support unit at the position where the ground subsidence moves downward with respect to the first support member and extends. Since the building is supported from below by the support unit, the inclination of the building due to ground subsidence is suppressed. At that time, since the second support member is urged downward by the urging means, the second support member moves downward so as to follow the ground subsidence. Further, since the movement of the second support member in the opposite direction is restricted by the movement restricting means, the second support member is held in a state of moving downward. In addition, each support unit is installed between the building main body side and the ground side pressure platen, and the pressure platen is inclined with respect to the building body due to ground subsidence. Only the position does not sink excessively, and the amount of settlement is distributed to each support unit.

本発明によれば、地盤沈下に応じて伸長した支持ユニットによって建物本体を支持することにより、建物本体の傾斜を抑制することができるので、傾斜した建物を修復するための大掛かりな工事を必要とせず、しかも建物の傾斜による梁、柱、建具等の歪みを生ずることがなく、地盤沈下による建物への被害を少なくすることができる。また、沈下した地盤を修復する場合でも、建物が支持ユニットによって水平状態に保持されているので、従来のように建物を油圧ジャッキ等で押し上げる必要がない分、地盤の修復工事を容易に行うことができる。この場合、第２の支持部材を付勢手段によって地盤沈下に追従するように下方に移動させることができるので、支持ユニットを地盤沈下に応じて確実に伸長させることができる。また、地盤沈下によって第２の支持部材が下方に移動した状態を保持することができるので、伸長した支持ユニットによって建物本体を確実に支持することができる。更に、沈下量を各支持ユニットに分散させることができるので、第２の支持部材の移動量を大きくする必要がなく、支持ユニットを上下方向に小型化することができる。 According to the present invention, the inclination of the building body can be suppressed by supporting the building body with the support unit extended according to the ground subsidence, so that a large-scale construction for repairing the inclined building is required. In addition, there is no distortion of the beams, columns, joinery, etc. due to the inclination of the building, and damage to the building due to ground subsidence can be reduced. Also, even when repairing the subsidized ground, the building is held in a horizontal state by the support unit , so it is not necessary to push up the building with a hydraulic jack, etc. Can do. In this case, since the second support member can be moved downward so as to follow the ground subsidence by the biasing means, the support unit can be reliably extended according to the ground subsidence. Moreover, since the state which the 2nd support member moved below by ground subsidence can be hold | maintained, a building main body can be reliably supported by the extended support unit. Furthermore, since the amount of settlement can be distributed to each support unit, it is not necessary to increase the amount of movement of the second support member, and the support unit can be downsized in the vertical direction.

同図に示す建物１は、例えば木造建築物からなる建物本体２を鉄筋コンクリート構造の耐圧盤３の上方に設置してなり、耐圧盤３は地盤側の地中に設けられている。建物本体２の土台２ａは補強フレーム４上に固定されており、補強フレーム４は土台２ａに沿って延びる鋼材からなる。   The building 1 shown in the figure is constructed by installing a building body 2 made of, for example, a wooden building above a reinforced concrete structure pressure platen 3, and the pressure platen 3 is provided in the ground on the ground side. The base 2a of the building body 2 is fixed on the reinforcing frame 4, and the reinforcing frame 4 is made of a steel material extending along the base 2a.

本実施形態の建物支持装置１０は、補強フレーム４と耐圧盤３との間に配置される複数の支持ユニット１１を備え、図３に示すように、各支持ユニット１１は建物１の前後方向及び幅方向に複数ずつ設置されている。   The building support apparatus 10 according to the present embodiment includes a plurality of support units 11 disposed between the reinforcing frame 4 and the pressure platen 3, and as shown in FIG. A plurality of them are installed in the width direction.

支持ユニット１１は、上端側を建物側に連結された第１の支持部材１２と、下端側を地盤側に接地された第２の支持部材１３と、第２の支持部材１３を第１の支持部材１２に対して下方に付勢する付勢手段としてのコイル状のスプリング１４と、第１の支持部材１２に対する第２の支持部材１３の上方への移動を規制する移動規制手段としてのストッパ機構１５とから構成されている。   The support unit 11 includes a first support member 12 whose upper end side is connected to the building side, a second support member 13 whose lower end side is grounded to the ground side, and the second support member 13 as a first support. A coil spring 14 as a biasing means for biasing the member 12 downward, and a stopper mechanism as a movement restricting means for restricting the upward movement of the second support member 13 relative to the first support member 12. 15.

第１の支持部材１２は上下方向に延びるピストン状の部材からなり、その上端には補強フレーム４を支持する第１の台座１２ａが設けられている。第１の台座１２ａの下端には第１の支持部材１２に螺合するネジ部１２ｂが設けられ、第１の台座１２ａを回動すると、ネジ部１２ｂによって第１の台座１２ａが第１の支持部材１２に対して上下動するようになっている。   The first support member 12 is a piston-like member extending in the vertical direction, and a first pedestal 12a for supporting the reinforcing frame 4 is provided at the upper end thereof. A screw portion 12b that is screwed into the first support member 12 is provided at the lower end of the first pedestal 12a. When the first pedestal 12a is rotated, the first pedestal 12a is first supported by the screw portion 12b. It moves up and down with respect to the member 12.

第２の支持部材１３は上端を開口したシリンダ状の部材からなり、その内部には第１の支持部材１２が上下方向に移動自在に挿入されている。第２の支持部材１３の下端側には耐圧盤３に固定される第２の台座１３ａが設けられ、第２の台座１３ａは、球体と球面を係合してなる自在継ぎ手１３ｂを介して第２の支持部材１３の下端に揺動自在に連結されている。   The 2nd support member 13 consists of a cylindrical member which opened the upper end, and the 1st support member 12 is inserted in the inside so that a movement to an up-down direction is possible. A second pedestal 13a fixed to the pressure-resistant panel 3 is provided on the lower end side of the second support member 13, and the second pedestal 13a is provided via a universal joint 13b formed by engaging a sphere and a spherical surface. The support member 13 is connected to the lower end of the second support member 13 in a swingable manner.

スプリング１４は第２の支持部材１３内に設けられ、第２の支持部材１３の底面と第２の支持部材１３の下端面との間に圧縮状態で配置されている。   The spring 14 is provided in the second support member 13 and is disposed in a compressed state between the bottom surface of the second support member 13 and the lower end surface of the second support member 13.

ストッパ機構１５は、第１の支持部材１２側に設けられた係止歯１５ａと、第２の支持部材１３側に設けられた係止爪１５ｂとからなり、係止爪１５ｂは第２の支持部材１３の周方向複数箇所に設けられている。係止歯１５ａは第１の支持部材１２の外周面に上下方向に配列されるとともに、第１の支持部材１２の全周に亘るように形成されている。係止爪１５ｂは第２の支持部材１３の周面を第２の支持部材１３の径方向に移動自在に貫通しており、その先端が係止歯１５ａに係止するようになっている。この場合、係止爪１５ｂの先端は係止歯１５ａに向かって上り傾斜をなし、係止歯１５ａは係止爪１５ｂに向かって下り傾斜をなしている。これにより、係止爪１５ｂは係止歯１５ａによって上方への移動を規制され、下方への移動は係止爪１５ｂが前記傾斜により係止歯１５ａから後退することにより許容されるようになっている。この場合、係止爪１５ｂはスプリング１５ｃによって係止歯１５ａ側に付勢されており、スプリング１５ｃは第２の支持部材１３の外面に取り付けられたケース１５ｄ内に収納されている。   The stopper mechanism 15 includes a locking tooth 15a provided on the first support member 12 side and a locking claw 15b provided on the second support member 13 side, and the locking claw 15b is a second support. The member 13 is provided at a plurality of locations in the circumferential direction. The locking teeth 15 a are arranged on the outer peripheral surface of the first support member 12 in the vertical direction and are formed so as to extend over the entire periphery of the first support member 12. The locking claw 15b penetrates the peripheral surface of the second support member 13 so as to be movable in the radial direction of the second support member 13, and its tip is locked to the locking teeth 15a. In this case, the front end of the locking claw 15b is inclined upward toward the locking tooth 15a, and the locking tooth 15a is inclined downward toward the locking claw 15b. As a result, the locking claw 15b is restricted from moving upward by the locking teeth 15a, and the downward movement is allowed when the locking claw 15b moves backward from the locking teeth 15a due to the inclination. Yes. In this case, the locking claw 15 b is biased toward the locking tooth 15 a by the spring 15 c, and the spring 15 c is accommodated in a case 15 d attached to the outer surface of the second support member 13.

以上のように構成された支持ユニット１１は、第１の台座１２ａを補強フレーム４に固定されるとともに、第２の台座１３ａを耐圧盤３に固定されることにより、建物本体２側と地盤側との間に設置される。その際、第１の台座１２ａを回動してネジ部１２ｂにより上下動させることにより、フレーム５に対する第１の台座１２ａの高さ位置を調整することができる。   In the support unit 11 configured as described above, the first pedestal 12a is fixed to the reinforcing frame 4 and the second pedestal 13a is fixed to the pressure-resistant panel 3 so that the building main body 2 side and the ground side are fixed. It is installed between. At that time, the height position of the first pedestal 12a relative to the frame 5 can be adjusted by rotating the first pedestal 12a and moving it up and down by the screw portion 12b.

前記建物支持装置１０においては、例えば地震による液状化現象で地盤沈下が発生すると、図６に示すように地盤沈下によって耐圧盤３が傾斜する。これにより、地盤沈下が生じた位置の支持ユニット１１では、図７に示すように地盤沈下により耐圧盤３が沈下した分だけ第２の支持部材１３が第１の支持部材１２に対して下方に移動する。その際、第２の支持部材１３はスプリング１４によって下方に付勢されていることから、第２の支持部材１３が耐圧盤３の沈下に追従するように下方に移動する。また、第２の支持部材１３はストッパ機構１５によって反対方向への移動を規制されることから、下方に移動した状態に保持される。即ち、地盤沈下が生じた位置の支持ユニット１１が地盤の沈下量に応じて上下方向に伸長することにより、建物本体２が水平状態に保持され、地盤沈下による建物本体２の傾斜が抑制される。この後、地盤沈下が進行した場合でも、地盤沈下の進行に応じて第２の支持部材１３が更に下方に移動して建物本体２の傾斜が抑制される。   In the building support apparatus 10, for example, when ground subsidence occurs due to a liquefaction phenomenon caused by an earthquake, the pressure-resistant panel 3 is inclined by the ground subsidence as shown in FIG. 6. As a result, in the support unit 11 at the position where the ground subsidence occurs, the second support member 13 is lowered with respect to the first support member 12 by the amount that the pressure platen 3 has subsided due to the ground subsidence, as shown in FIG. Moving. At this time, since the second support member 13 is biased downward by the spring 14, the second support member 13 moves downward so as to follow the settlement of the pressure-resistant platen 3. Further, since the second support member 13 is restricted from moving in the opposite direction by the stopper mechanism 15, the second support member 13 is held in a state of moving downward. That is, the support unit 11 at the position where the ground subsidence extends in the vertical direction according to the amount of ground subsidence, so that the building main body 2 is held in a horizontal state, and the inclination of the building main body 2 due to the ground subsidence is suppressed. . Thereafter, even when the land subsidence proceeds, the second support member 13 moves further downward in accordance with the progress of the land subsidence, and the inclination of the building body 2 is suppressed.

このように、本実施形態によれば、上端側を建物側に連結された第１の支持部材１２と、下端側を地盤側に接地された第２の支持部材１３と、第２の支持部材１３を第１の支持部材１２に対して下方に付勢するスプリング１４と、第１の支持部材１２に対する第２の支持部材１３の上方への移動を規制するストッパ機構１５とからなる複数の支持ユニット１１を建物本体２側と地盤側との間に配置し、地盤沈下した位置の第２の支持部材１３をスプリング１４によって下方に移動させることにより、建物本体２を下方から支持するようにしたので、地盤沈下による建物本体２の傾斜を支持ユニット１１によって抑制することができ、建物本体２を水平状態に保つことができる。これにより、傾斜した建物を修復するための大掛かりな工事を必要とせず、しかも地盤沈下によって建物が大きく傾くことがないので、建物の傾斜による梁、柱、建具等の歪みを生ずることがなく、地盤沈下による建物への被害を少なくすることができる。また、沈下した地盤を修復する場合でも、建物本体２が支持ユニット１１によって水平状態に保持されているので、従来のように建物を油圧ジャッキ等で押し上げる必要がない分、地盤の修復工事を容易に行うことができる。   Thus, according to the present embodiment, the first support member 12 whose upper end side is connected to the building side, the second support member 13 whose lower end side is grounded to the ground side, and the second support member. A plurality of supports comprising a spring 14 for urging 13 downward with respect to the first support member 12 and a stopper mechanism 15 for restricting upward movement of the second support member 13 relative to the first support member 12. The unit 11 is disposed between the building body 2 side and the ground side, and the second supporting member 13 at the position where the ground sinks is moved downward by the spring 14 to support the building body 2 from below. Therefore, the inclination of the building main body 2 due to ground subsidence can be suppressed by the support unit 11, and the building main body 2 can be maintained in a horizontal state. This eliminates the need for extensive construction work to repair the tilted building, and the building does not tilt significantly due to ground subsidence, so there is no distortion of the beams, columns, fixtures, etc. due to the building tilt. Damage to buildings due to land subsidence can be reduced. Even when the subsidized ground is repaired, since the building body 2 is held in a horizontal state by the support unit 11, it is not necessary to push up the building with a hydraulic jack or the like as in the prior art, so that the ground can be repaired easily. Can be done.

この場合、第２の支持部材１３をスプリング１４によって下方に付勢するようにしているので、第２の支持部材１３を地盤沈下に追従するように下方に移動させることができ、支持ユニット１１を地盤沈下に応じて確実に伸長させることができる。   In this case, since the second support member 13 is urged downward by the spring 14, the second support member 13 can be moved downward so as to follow the ground subsidence, and the support unit 11 can be moved. It can be reliably extended according to land subsidence.

また、第２の支持部材１３の反対方向への移動をストッパ機構１５によって規制するようにしたので、地盤沈下によって第２の支持部材１３が下方に移動した状態を確実に保つことができ、伸長した支持ユニット１１によって建物本体２を確実に支持することができる。   Further, since the movement of the second support member 13 in the opposite direction is restricted by the stopper mechanism 15, the state where the second support member 13 has moved downward due to the ground subsidence can be reliably maintained and extended. The building main body 2 can be reliably supported by the support unit 11.

更に、第１の支持部材１２及び第２の支持部材１３を互いに上下方向に摺動自在に係合するシリンダ状の部材及びピストン状の部材によって形成するとともに、スプリング１４を第１の支持部材１２と第２の支持部材１３との間に圧縮状態で配置したので、第１の支持部材１２、第２の支持部材１３及びスプリング１４を同軸状に配置することができ、支持ユニット１１を幅方向に小型化することができる。   Further, the first support member 12 and the second support member 13 are formed by a cylinder-like member and a piston-like member that are slidably engaged with each other in the vertical direction, and the spring 14 is formed by the first support member 12. Since the first support member 12, the second support member 13, and the spring 14 can be coaxially arranged, the support unit 11 is arranged in the width direction. Can be reduced in size.

また、ストッパ機構１５を、第１の支持部材１２側に上下方向に配列された係止歯１５ａに第２の支持部材１３側に設けられた係止爪１５ｂを係止するように構成したので、第２の支持部材１３の反対方向への移動を第２の支持部材１３が移動した位置で確実に規制することができ、建物本体２を地盤の沈下量に応じて的確に支持することができる。   Further, the stopper mechanism 15 is configured so that the locking claw 15b provided on the second support member 13 side is locked to the locking teeth 15a arranged in the vertical direction on the first support member 12 side. The movement of the second support member 13 in the opposite direction can be reliably restricted at the position where the second support member 13 has moved, and the building body 2 can be accurately supported according to the amount of ground subsidence. it can.

更に、各支持ユニット１１を、建物本体２の底面側に設けられた補強フレーム４と地盤側に設けられた耐圧盤３との間に設置し、建物本体２に対して耐圧盤３が地盤沈下によって傾斜するようにしたので、一部の支持ユニット１１の設置位置のみが過度に沈下することがなく、沈下量を各支持ユニット１１に分散させることができる。これにより、第２の支持部材１３の移動量を大きくする必要がなく、支持ユニット１１を上下方向に小型化することができる。   Furthermore, each support unit 11 is installed between the reinforcing frame 4 provided on the bottom surface side of the building body 2 and the pressure board 3 provided on the ground side, and the pressure board 3 sinks to the building body 2. Therefore, only the installation positions of some of the support units 11 do not sink excessively, and the amount of settlement can be distributed to each support unit 11. Thereby, it is not necessary to increase the movement amount of the second support member 13, and the support unit 11 can be downsized in the vertical direction.

この場合、各支持ユニット１１は建物本体２の補強フレーム４を支持しているので、補強フレーム４によって地盤沈下時の建物本体２の歪みを抑制することができる。   In this case, since each support unit 11 supports the reinforcing frame 4 of the building body 2, the reinforcing frame 4 can suppress distortion of the building body 2 when the ground sinks.
