ところが、上記既出願の振動伝播阻止方法では、図20に示すように、廃タイヤ重合連結体1は、岩盤等の硬い頑丈な支持層に固定されておらず、ほとんどが軟弱層内に埋設されていることから、振動発生源からの振動によって廃タイヤ重合連結体それ自体が揺れを生じ易く、しかもこれが共振を起こし易くなるため、振動源からの振動の吸収ないし反射作用が低下し、住宅24等建物への振動の伝播を十分阻止し得ないことがある。
However, in the above-described vibration propagation preventing method, as shown in FIG. 20, the waste tire polymerization connector 1 is not fixed to a hard and strong support layer such as a rock, and most of it is embedded in the soft layer. Therefore, the waste tire polymerization connector itself tends to sway due to vibration from the vibration source, and moreover it tends to resonate, so that the absorption or reflection of vibration from the vibration source is reduced, and the house 24 It may not be possible to sufficiently prevent the propagation of vibrations to buildings.
即ち、地盤中を伝わる振動の波は硬い地盤ほど速く伝播し、軟らかい地盤ほどその速度は遅くなる。この遅いというのは、1周期の間に波の進む距離(波長)が短くなるということである。一つの波に含まれるエネルギーは土の種類によって変わることがないので、軟らかい地盤を伝わる波は波長が短くなる分、振幅が増大して、エネルギーを一定に保とうとし、これが軟弱地盤のよく揺れる理由である。そして、廃タイヤ重合連結体1には、これが揺れる時に振動体として固有の周期を有しており、この固有周期が振動源から伝播する振動の周期に近づいたり、同じになって重なると、廃タイヤ重合連結体1の揺れが加速されて、より大きく揺れるようになり、これが共振であって、この共振作用によって、振動伝播阻止作用が十分発に揮し得なくなる。
That is, the vibration wave propagating in the ground propagates faster in the hard ground, and the speed becomes slower in the soft ground. This slow means that the distance (wavelength) that the wave travels during one period is shortened. Since the energy contained in one wave does not change depending on the type of soil, the wave that travels on the soft ground will increase in amplitude as the wavelength becomes shorter, trying to keep the energy constant, which is why the soft ground often shakes It is. The waste tire polymerization connector 1 has a natural period as a vibrating body when it is swayed. When the natural period approaches or becomes the same as the period of vibration propagating from the vibration source, The vibration of the tire superposition | polymerization coupling body 1 is accelerated, and it shakes more greatly, and this is a resonance, and this resonance action cannot fully exhibit a vibration propagation prevention effect.
そこで、本発明は、地盤中に埋設される廃タイヤ重合連結体の揺れを極力少なくして、廃タイヤ重合連結体が振動源からの振動の吸収ないし反射作用を十分に発揮し得るようにした振動伝播阻止方法を提供することを目的とする。
In view of this, the present invention minimizes the vibration of the waste tire polymerization connector embedded in the ground so that the waste tire polymerization connector can sufficiently absorb or reflect the vibration from the vibration source. An object is to provide a vibration propagation preventing method.

The concrete loaded bodies 10 and 11 are placed by burying a large number of waste tire polymerization connectors 1 in the ground, and the cores 14 and 18 of each waste tire polymerization connector 1 through the anchor reinforcing bars 5 and the support layer G3. After being fixed to the concrete, a concrete formwork is temporarily installed on the heads of the numerous waste tire polymerization connectors 1, and concrete may be poured into them.

図1及び図2によって説明した振動伝播阻止方法は、タイヤ外周部より周方向適当間隔置きに半径方向の切り込み3を入れた多数の廃タイヤ2の中央開口部、又は廃タイヤ2をタイヤ幅方向に分割した多数の分割タイヤ4の中央開口部に亘って鋼管やコンクリートパイル等の芯体14,18を嵌挿し、これら多数の廃タイヤ2又は分割タイヤ4を互いに圧縮した状態で芯体14,18に対し固定してなる多数本の廃タイヤ重合連結体1を、車両27の走行や各種機械の稼動によって振動する構造物又は道路とこれの近くに設置された住宅等建物との間の地盤中に所要配列状態で埋設したことにより、地盤中の廃タイヤ重合連結体1を形成する各廃タイヤ2又は分割タイヤ4の緩衝作用によって、この廃タイヤ2又は分割タイヤ4に伝わってくる大きな振動を吸収して減衰させ、反対側への伝播を阻止することができ、構造物又は道路から住宅等建物への振動の伝播を阻止し、住宅等建物が受ける振動の影響を極力少なくすることができる。
The vibration propagation preventing method described with reference to FIG. 1 and FIG. 2 uses a plurality of waste tires 2 having central openings in the tire width direction in which radial incisions 3 are provided at appropriate intervals in the circumferential direction from the tire outer periphery. The core bodies 14 and 18 such as steel pipes and concrete piles are fitted and inserted over the central openings of the large number of divided tires 4 divided into a large number of the divided tires 4 and the core bodies 14 and the divided tires 4 in a compressed state. The ground between the structure or road that vibrates by the traveling of the vehicle 27 and the operation of various machines and a building such as a house installed in the vicinity of the waste tire polymerization connector 1 fixed to the 18 By being buried in the required arrangement state, it is transmitted to the waste tire 2 or the divided tire 4 by the buffering action of each waste tire 2 or the divided tire 4 that forms the waste tire polymerization connected body 1 in the ground. Absorbs and attenuates large vibrations, preventing propagation to the other side, preventing the propagation of vibrations from structures or roads to buildings such as houses, and minimizing the effects of vibrations on buildings such as houses be able to.
特にこの方法では、各廃タイヤ重合連結体1の芯体14,18をアンカー鉄筋5を介して支持層G3に固定するようにしたから、各廃タイヤ重合連結体1の上部側が軟弱層G1中にあっても、各廃タイヤ重合連結体1は、振動発生源からの振動によって廃タイヤ重合連結体1それ自体が揺れを生じ難く、従って廃タイヤ重合連結体1が共振を起こし難くなり、それがために廃タイヤ重合連結体1が振動源からの振動の吸収ないし反射作用を十分に発揮して、振動発生源から住宅等の建物に伝播する振動を有効に阻止することができる。
In particular, in this method, since the core bodies 14 and 18 of each waste tire polymerization connector 1 are fixed to the support layer G3 via the anchor reinforcing bars 5, the upper side of each waste tire polymerization connector 1 is in the soft layer G1. Even in such a case, the waste tire polymerization connectors 1 are less likely to shake due to vibration from the vibration source, and therefore the waste tire polymerization connectors 1 are less likely to resonate. Therefore, the waste tire polymerization connector 1 can sufficiently absorb or reflect the vibration from the vibration source, and can effectively prevent the vibration propagating from the vibration source to the building such as a house.
また、各廃タイヤ重合連結体1の頭部上にコンクリート載荷体10,11を載設した場合には、各廃タイヤ重合連結体1の芯体14,18を支持層G3に対してより安定状態に固定することができる。
Moreover, when the concrete loading bodies 10 and 11 are mounted on the head of each waste tire polymerization coupling body 1, the core bodies 14 and 18 of each waste tire polymerization coupling body 1 are more stable with respect to the support layer G3. Can be fixed to the state.
また、各廃タイヤ重合連結体1の芯体14,18を支持層G3に固定するアンカー鉄筋5は、芯体14,18をその軸芯に沿って貫通すると共に、鉄筋5の下端部を支持層G3に根固めされる根固め材7に固定し且つ鉄筋5の上端部を芯体14,18の頭部側に固定することによって、芯体14,18及び支持層G3への取付作業を的確に行なうことができる。
Further, the anchor reinforcing bar 5 that fixes the core bodies 14 and 18 of each waste tire polymerization connector 1 to the support layer G3 penetrates the core bodies 14 and 18 along the axis and supports the lower end portion of the reinforcing bars 5. Fixing to the core material 7 fixed to the layer G3 and fixing the upper end of the reinforcing bar 5 to the head side of the core bodies 14 and 18 enables the attachment work to the core bodies 14 and 18 and the support layer G3. It can be done accurately.
図4は、図20に示すように車両27の走行により振動する道路28とこの道路28の近くに設置された住宅24等建物との間の地盤G中に多数本の廃タイヤ重合連結体1を1列状に埋設すると共に、各廃タイヤ重合連結体1の芯体14,18の先端部を支持層G3に根入れした状態を示す側面断面図、図5の(a) は図4に示す廃タイヤ重合連結体1の配列状態を地盤表面から見た平面図、(b) は(a) のY−Y線拡大断面図である。尚、図5の(b) は、廃タイヤ重合連結体1が鋼管PHCパイルからなる芯体18を有する場合を示している。
FIG. 4 shows a large number of waste tire superposed connectors 1 in the ground G between a road 28 that vibrates as the vehicle 27 travels and a building such as a house 24 installed near the road 28 as shown in FIG. Are embedded in one row, and a side cross-sectional view showing a state in which the leading ends of the core bodies 14 and 18 of each waste tire polymerization connector 1 are embedded in the support layer G3. FIG. 5 (a) is shown in FIG. The top view which looked at the arrangement | sequence state of the waste tire superposition | polymerization coupling body 1 shown from the ground surface, (b) is the YY expanded sectional view of (a). FIG. 5 (b) shows a case where the waste tire polymerization connector 1 has a core body 18 made of a steel pipe PHC pile.
各廃タイヤ重合連結体1は、廃タイヤ2又は分割タイヤ4が地盤の軟弱層G1のほぼ全域に亘るように埋設されると共に、芯体14,18が軟弱層G1及び硬質層G2を貫通して、その先端部が支持層G3に根入れされている。
Each waste tire polymerization connector 1 is embedded so that the waste tire 2 or the divided tire 4 extends over substantially the entire soft layer G1 of the ground, and the core bodies 14 and 18 penetrate the soft layer G1 and the hard layer G2. Thus, the tip portion is embedded in the support layer G3.
廃タイヤ重合連結体1の埋設施工にあたっては、スクリューオーガーにより地盤を掘削しつつ排土しながら軟弱層G1から硬質層G2までは廃タイヤ2又は分割タイヤ4が貫入し得るように比較的径の大きい孔を掘孔し、支持層G3からは芯体14,18が貫入するように別のスクリューオーガーにより比較的径小の孔を支持層G3所定深さまで掘孔し、こうして掘孔した一連の孔にセメントミルクを注入した後、セメントミルクの溜まった孔内にクレーンにより廃タイヤ重合連結体1を落とし込み、芯体14,18の先端部を支持層G3の根入れ用孔部に挿入して根入れする。
When the waste tire polymerization connector 1 is buried, the ground tire 2 is excavated by a screw auger and the soil is excavated while the ground layer 2 is divided so that the waste tire 2 or the divided tire 4 can penetrate from the soft layer G1 to the hard layer G2. A series of drilled holes having a relatively small diameter to a predetermined depth by a separate screw auger so that the cores 14 and 18 penetrate from the support layer G3. After injecting the cement milk into the hole, the waste tire polymerization connector 1 is dropped into the hole where the cement milk is accumulated by a crane, and the tips of the core bodies 14 and 18 are inserted into the holes for rooting of the support layer G3. Root.
こうして各廃タイヤ重合連結体1を軟弱層G1から硬質層G2に埋入すると共に、芯体14,18の先端部を支持層G3に根入れした後、図5の(a),(b) に示すように、各廃タイヤ重合連結体1の頭部上に亘って、例えばC形鋼からなる2本の連結部材8,8を並置し、この連結部材8を、各廃タイヤ重合連結体1の芯体18の上端にボルト40で取り付けてある固定部材15に例えば溶接によって固着する。
In this way, each waste tire polymerization coupling body 1 is embedded from the soft layer G1 to the hard layer G2, and the tips of the core bodies 14 and 18 are embedded in the support layer G3, and then (a) and (b) in FIG. As shown in Fig. 2, two connecting members 8 and 8 made of, for example, C-shaped steel are juxtaposed over the head of each waste tire polymerization connector 1, and this connection member 8 is connected to each waste tire polymerization connector. The fixing member 15 is fixed to the upper end of one core body 18 with a bolt 40, for example, by welding.
上記のように各廃タイヤ重合連結体1を地盤中に埋設すると共に、その芯体14,18の先端部を支持層G3に根入れすることによって、各廃タイヤ重合連結体1は、上部側が軟弱層G1中にあっても、振動発生源からの振動によって廃タイヤ重合連結体1それ自体が揺れを生じ難く、従って廃タイヤ重合連結体1が共振を起こし難くなり、それがために廃タイヤ重合連結体1が振動源からの振動の吸収ないし反射作用を十分に発揮して、振動発生源から住宅等の建物に伝播する振動を有効に阻止することができる。
As described above, each waste tire polymerization connector 1 is embedded in the ground, and the ends of the core bodies 14 and 18 are embedded in the support layer G3, so that each waste tire polymerization connector 1 has an upper side. Even in the soft layer G1, the waste tire polymerization connector 1 itself does not easily shake due to vibration from the vibration generation source, and therefore the waste tire polymerization connector 1 does not easily resonate. The superposition | polymerization coupling body 1 can fully exhibit the absorption or reflection effect | action of the vibration from a vibration source, and can prevent the vibration which propagates to buildings, such as a house, from a vibration generation source.
この場合、各廃タイヤ重合連結体1の芯体14,18の先端部を支持層G3に単に根入するだけでなく、その根入れ部分をセメントミルクによって支持層G3の根入れ用孔部内に固着することによって、各廃タイヤ重合連結体1の芯体14,18を支持層G3に対しきわめて強固に連結固定することができ、振動発生源から住宅等の建物に伝播する振動を一層有効に阻止することができる。
In this case, not only the front ends of the core bodies 14 and 18 of each waste tire polymerization connector 1 are inserted into the support layer G3, but also the roots are inserted into the hole for rooting of the support layer G3 with cement milk. By fixing, the core bodies 14 and 18 of each waste tire polymerization connector 1 can be very firmly connected and fixed to the support layer G3, and vibrations propagating from a vibration source to a building such as a house can be made more effective.

If the heads of the cores 14 and 18 of each waste tire polymerization connector 1 are connected to each other by the connecting member 8, the vibration-proof walls formed by the many waste tire polymerization connectors 1 are integrated. As in the case of fixing to the support layer G <b> 3 by anchor reinforcing bars 5 or penetration, it is possible to prevent the waste tire polymerization connector 1 itself from shaking and the resonance of the waste tire polymerization connector 1.

In this state, the ring-shaped fixing member 15 may be fitted into the other end of the steel pipe 14 and fixed by welding. As the core body, in addition to the steel pipe 14, a hard plastic core body, a concrete core body, or the like can be used. Further, the fixing member 15 is not limited to the one that is welded and attached to the steel pipe 14 as described above. For example, one end portion or both end portions are protruded from the outer peripheral surface of the core body through a through hole provided in the steel pipe 14. A round bar or the like that is attached and fixed to the state may be used.
図12の(b-1) は、図12の(a-1) に示す廃タイヤ重合連結体1と殆ど同じであるが、多数の廃タイヤ2を嵌挿させた芯体としての鋼管14の両端部に夫々コンクリート製のリング状押え17を介して、アングル片からなる複数個の固定部材16を固着してなる廃タイヤ重合連結体1を示す縦断面図であり、(b-2) はこの廃タイヤ重合連結体1の平面図である。この場合、アングル片からなる固定部材16は溶接により鋼管14に取り付ける。また、このようなアングル片からなる固定部材16に代えて、図20の(a-1) に示すリング状の固定部材15を使用してもよい。コンクリート製のリング状押え17は、鋼管14に嵌挿した廃タイヤ2のタイヤ軸方向に圧縮変形させる際の錘の役割を有する。
(B-1) in FIG. 12 is almost the same as the waste tire polymerization connector 1 shown in (a-1) in FIG. 12, but the steel pipe 14 as a core body into which a large number of waste tires 2 are inserted is shown.

Further, instead of the fixing member 16 formed of such an angle piece, a ring-shaped fixing member 15 shown in FIG. 20 (a-1) may be used. The concrete ring-shaped presser 17 has a role of a weight when compressing and deforming the waste tire 2 fitted in the steel pipe 14 in the tire axial direction.
図13の(a-1) は、図12の(a-1) に示す廃タイヤ重合連結体1と殆ど同じであって、廃タイヤ2の代わりに分割タイヤ4aを使用した点だけが異なった廃タイヤ重合連結体1の縦断面図、(a-2) はその平面図である。また、図13の(b-1) は、図13の(b-1) に示す廃タイヤ重合連結体1と殆ど同じであって、廃タイヤ2の代わりに分割タイヤ4aを使用した点だけが異なった廃タイヤ重合連結体1の縦断面図、(b-2) は平面図である。
(A-1) in FIG. 13 is almost the same as the waste tire polymerization connector 1 shown in (a-1) in FIG. 12, except that a split tire 4a is used instead of the waste tire 2. The longitudinal cross-sectional view of the waste tire superposition | polymerization coupling body 1, (a-2) is the top view. Further, (b-1) in FIG. 13 is almost the same as the waste tire polymerization connector 1 shown in FIG. 13 (b-1), and only the divided tire 4a is used instead of the waste tire 2. FIG. 5 is a longitudinal sectional view of different waste tire polymerization connectors 1, and (b-2) is a plan view.
上記した図12及び図13に示すような廃タイヤ重合連結体1によれば、夫々切り込み3を設けた多数の廃タイヤ2又はタイヤ幅方向に分割した多数の分割タイヤ4の中央開口部2o,4oに亘って鋼管14等の芯体を嵌挿し、この芯体の両端部に取り付けられる固定部材15,16により、これら多数の廃タイヤ2又は分割タイヤ4aを互いに圧縮した状態でその上下両端側を固定するようにしたものであり、鋼管14等の芯体によって廃タイヤ重合連結体1の自重が増し、剛性が確保されるため、地盤中で安定した状態となり、周辺の地盤の振動に対し抵抗性があって廃タイヤ重合連結体1自体が振動を生ずることがなく、外周部の圧縮した廃タイヤ2又は分割タイヤ4で振動を吸収し又は反射して制振作用を働かせることができ、免震杭として非常に有効である。
According to the waste tire polymerization connector 1 as shown in FIG. 12 and FIG. 13 described above, the central openings 2o of the multiple waste tires 2 provided with the cuts 3 or the multiple divided tires 4 divided in the tire width direction, respectively. A core body such as a steel pipe 14 is fitted over 4o, and the upper and lower end sides of the waste tire 2 or the divided tire 4a are compressed with fixing members 15 and 16 attached to both ends of the core body. Since the weight of the waste tire polymerized connected body 1 is increased by the core body such as the steel pipe 14 and the rigidity is secured, it becomes a stable state in the ground, and the vibration of the surrounding ground There is resistance and the waste tire polymerization connector 1 itself does not generate vibrations, and the vibrations can be absorbed or reflected by the waste tires 2 or the divided tires 4 compressed at the outer periphery to act the damping action. Seismic isolation It is very effective as.
図14は、図12に示す廃タイヤ重合連結体1と同じ様に、多数の廃タイヤ2に芯体を嵌挿して廃タイヤ重合連結体1を形成したものであるが、ここではPHCパイルからなる芯体18を使用したものであり、(a) は縦断面図、(b) は平面図である。このPHCパイルは、中空状のコンクリートパイル本体19の上下両端部にリング状の金属製座金20,20が取り付けられると共に、上下両座金20,20間のコンクリートパイル本体19内に田とカバ8本のPC鋼線33が周方向に45°の間隔で貫通張架され、また上下各座金20には周方向に隣り合うPC鋼線33,33の間にボルト孔34が設けてある。この廃タイヤ重合連結体1を形成するには、夫々切り込み3を設けた多数の廃タイヤ2にPHCパイルからなる芯体18を嵌挿し、これら多数の廃タイヤ2を互いにタイヤ軸方向に圧縮した状態で、リング状固定部材15,15をPHCパイル芯体18の上下両端部にある座金20,20に夫々溶接すればよい。
FIG. 14 shows a structure in which a waste tire polymerization connector 1 is formed by inserting a core body into a large number of waste tires 2 in the same manner as the waste tire polymerization connector 1 shown in FIG. The core body 18 is used, (a) is a longitudinal sectional view, and (b) is a plan view. In this PHC pile, ring-shaped metal washers 20 and 20 are attached to the upper and lower ends of a hollow concrete pile body 19, and eight fields and covers are provided in the concrete pile body 19 between the upper and lower washers 20 and 20. The PC steel wire 33 is stretched through at an interval of 45 ° in the circumferential direction, and the upper and lower washers 20 are provided with bolt holes 34 between the PC steel wires 33 and 33 adjacent in the circumferential direction. In order to form the waste tire polymerization connector 1, cores 18 made of PHC piles are fitted into a large number of waste tires 2 each provided with cuts 3, and the waste tires 2 are compressed together in the tire axial direction. In this state, the ring-shaped fixing members 15 and 15 may be welded to the washers 20 and 20 at the upper and lower ends of the PHC pile core body 18 respectively.
尚、廃タイヤ2にその外周部より切り込み3を設けた廃タイヤ重合連結体1にあっては、廃タイヤ重合連結体1の外周面が従来の廃タイヤ重合連結体1よりも多岐に亘って小刻みに凹凸状を呈しているから、振動をより効果的に乱反射させることができ、それにより廃タイヤ重合連結体1の制振・防振効果をより一層高めることができる。
In addition, in the waste tire polymerization connector 1 in which the cut 3 is provided in the waste tire 2 from the outer peripheral portion, the outer peripheral surface of the waste tire polymerization connector 1 is more diverse than the conventional waste tire polymerization connector 1. Since the unevenness is formed in small increments, vibrations can be diffused more effectively, thereby further enhancing the vibration damping / vibration preventing effect of the waste tire polymerization connector 1.
図15は更に他の廃タイヤ重合連結体1を示す。(a) に示す廃タイヤ重合連結体1は、夫々切り込み3を設けた多数の廃タイヤ2に対し複数本の連結用軸材35を周方向に所要間隔を置いて軸方向に貫通させると共に、これら多数の廃タイヤ2に例えばPHCパイルからなる芯体18を嵌挿し、更にこれら多数の廃タイヤ2の上下両端には連結用軸材35を貫通させた固定部材36,36を当てがい、そしてこれら多数の廃タイヤ2を図15の(b) に示すようにタイヤ軸方向に圧縮した状態で上下両固定部材36,36を、各連結用軸材35の上下両端部側に螺着した長ナット37,37で締め付け固定すると共に、各連結用軸材35の上下両端部を、PHCパイル18の両端面にボルト38で固定した固定プレート39,39に挿通し、その挿通端部にナット41を螺合して締め付けることにより、形成されたものである。尚、連結用軸材35としては、PC鋼線、異形鉄筋、丸鋼が使用され、そして何れも少なくとも上下両端部に雄ねじが切られている。このように、互いに圧縮される多数の廃タイヤ2に対し複数本の連結用軸材35を周方向に所要間隔を置いて軸方向に貫通させるようにすれば、これら多数の廃タイヤ2の中央開口部への芯体14,18の嵌挿が容易で、廃タイヤ重合連結体1の組み付けが容易となる。
FIG. 15 shows still another waste tire polymerization connector 1. In the waste tire polymerization connector 1 shown in (a), a plurality of connecting shaft members 35 are penetrated in the axial direction at a predetermined interval in the circumferential direction with respect to a large number of waste tires 2 each provided with cuts 3. A core body 18 made of, for example, a PHC pile is inserted into the large number of waste tires 2, and fixing members 36, 36 through which connecting shaft members 35 penetrate are applied to the upper and lower ends of the large numbers of waste tires 2. As shown in FIG. 15 (b), the upper and lower fixing members 36, 36 are screwed to the upper and lower end portions of each connecting shaft 35 in a state in which these many waste tires 2 are compressed in the tire axial direction. The nuts 37 and 37 are fastened and fixed, and both upper and lower end portions of each connecting shaft 35 are inserted into fixing plates 39 and 39 fixed to both end surfaces of the PHC pile 18 with bolts 38, and nuts 41 are inserted into the insertion end portions. Screw and tighten More, and is formed. In addition, as the connecting shaft member 35, a PC steel wire, a deformed rebar, and a round steel are used, and any of them has male threads cut at least at both upper and lower ends. In this way, if a plurality of connecting shaft members 35 are penetrated in the axial direction at a predetermined interval in the circumferential direction with respect to a large number of waste tires 2 compressed together, the center of the large number of waste tires 2 is obtained. The core bodies 14 and 18 can be easily inserted into the opening, and the assembly of the waste tire polymerization connector 1 is facilitated.
図16 に示す廃タイヤ重合連結体1は、図15 に示す廃タイヤ重合連結体1と同様に互いに圧縮される多数の廃タイヤ2に対し複数本の連結用軸材35を周方向に所要間隔を置いて軸方向に貫通させたものであるが、この廃タイヤ重合連結体1にあっては、多数の廃タイヤ2又は分割タイヤ4の圧縮力を調整可能にして、廃タイヤ重合連結体1の固有振動数を調整できるようしたものである。即ち、図15の廃タイヤ重合連結体1と同様に、多数の廃タイヤ2に対し複数本の連結用軸材35を周方向に所要間隔を置いて軸方向に貫通させると共に、これら多数の廃タイヤ2に例えばPHCパイルからなる芯体18を嵌挿し、これら多数の廃タイヤ2の下端側を、芯体18に対しスライド可能で各連結用軸材35の下端部に止着されるリング状の可動部材50によって支持し、これら多数の廃タイヤ2の上端部側を、芯体18の上端部に固定された固定部材39によって支持すると共に、各連結用軸材35の上端部を油圧式のジャッキ43に連動連結し、しかして芯体18の上端部の固定部材39と下端部側の可動部材50との間で互いに圧縮状態に保持される多数の廃タイヤ2又は分割タイヤ4の圧縮力をジャッキ43によって調整可能としたものである。
The waste tire polymerization connector 1 shown in FIG. 16 has a plurality of connecting shaft members 35 in the circumferential direction with respect to a large number of waste tires 2 compressed together like the waste tire polymerization connector 1 shown in FIG. In this waste tire polymerization connector 1, the waste tire polymerization connector 1 can be adjusted by adjusting the compression force of a large number of waste tires 2 or divided tires 4. The natural frequency of can be adjusted. That is, in the same manner as the waste tire polymerization connector 1 in FIG. 15, a plurality of connecting shafts 35 are penetrated in the axial direction at a predetermined interval in the circumferential direction with respect to a large number of waste tires 2 and A ring body 18 is inserted into the tire 2, for example, a PHC pile, and the lower ends of the many waste tires 2 are slidable with respect to the core body 18 and fastened to the lower ends of the connecting shaft members 35. Are supported by a movable member 50, and the upper end portions of the many waste tires 2 are supported by a fixing member 39 fixed to the upper end portion of the core body 18, and the upper end portions of the respective connecting shaft members 35 are hydraulically operated. Of a large number of waste tires 2 or divided tires 4 that are held in a compressed state between the fixed member 39 at the upper end of the core body 18 and the movable member 50 at the lower end. Adjusting force with jack 43 It is obtained by Noh.
上記可動部材50は、各連結用軸材35の下端部に螺着されたナット42によって保持され、また各連結用軸材35の上端部は、芯体18の上端部の固定部材39を貫通して上方に突出し、テンションプレート46を支持する複数の引張ボルト45の夫々にカプラージョイント44を介して連結されている。そして、芯体18の上端部の固定部材39上にジャッキ43が設置され、このジャッキ43とテンションプレート46との間にロードセル47が介設されている。図16において、48は各連結用軸材35の上端部に螺着された固定用ナット、49は引張ボルト45の上端部に螺着されたテンションプレート取付用ナットである。引張ボルト45は、必要に応じて所要長さのものと交換できるようになっている。
The movable member 50 is held by a nut 42 screwed to the lower end portion of each connecting shaft member 35, and the upper end portion of each connecting shaft member 35 penetrates the fixing member 39 at the upper end portion of the core body 18. The plurality of tension bolts 45 projecting upward and supporting the tension plate 46 are connected to each other via a coupler joint 44. A jack 43 is installed on the fixing member 39 at the upper end of the core body 18, and a load cell 47 is interposed between the jack 43 and the tension plate 46. In FIG. 16, 48 is a fixing nut screwed to the upper end portion of each connecting shaft 35, and 49 is a tension plate mounting nut screwed to the upper end portion of the tension bolt 45. The tension bolt 45 can be replaced with one having a required length as required.
多数の廃タイヤ2は、常時、固定部材39と下端部側の可動部材50との間で所要圧力に圧縮された状態にあり、この圧縮力はロードセル47によって検出することができる。しかして、斯かる状態から圧縮力を調整する時は、ジャッキ43操作によってテンションプレート46を上動させると、引張ボルト45及び連結用軸材35が引き上げられて、可動部材50が上動するから、圧縮力が増大し、またジャッキ43操作によってテンションプレート46を下動させると、引張ボルト45及び連結用軸材35が押し下げられて、可動部材50が下動するから、圧縮力が減少する。こうして廃タイヤ3の圧縮力を加減することにより、廃タイヤ重合連結体1の固有振動数をコントロールすることができる。この廃タイヤ重合連結体1は、地盤の状況、振動源の大きさや種類等によって、伝播する振動の固有振動数が変化することから、その変化する固有振動数に対応して廃タイヤ重合連結体1自体の固有振動数を変更調整することができるようにしたもので、それによって振動源からの振動の伝播をより有効に阻止することができる。
Many waste tires 2 are always compressed to a required pressure between the fixed member 39 and the movable member 50 on the lower end side, and this compressive force can be detected by the load cell 47. Therefore, when adjusting the compression force from such a state, if the tension plate 46 is moved upward by the operation of the jack 43, the tension bolt 45 and the connecting shaft member 35 are pulled up, and the movable member 50 moves upward. When the compression force is increased and the tension plate 46 is moved downward by the operation of the jack 43, the tension bolt 45 and the connecting shaft 35 are pushed down, and the movable member 50 is moved downward, so that the compression force decreases. In this way, by adjusting the compressive force of the waste tire 3, the natural frequency of the waste tire polymerization connector 1 can be controlled. Since the natural frequency of the propagating vibration changes depending on the ground condition, the size and type of the vibration source, etc., the waste tire superposed connector 1 corresponds to the changing natural frequency. The natural frequency of 1 itself can be changed and adjusted, whereby the propagation of vibration from the vibration source can be more effectively prevented.
また、この廃タイヤ重合連結体1では、ジャッキ43によって複数本、例えば4本ある連結用軸材35を同時に上げ下げ操作できるから、圧縮力が調整が簡単容易となる。
Moreover, in this waste tire superposition | polymerization coupling body 1, since the multiple shafts 35, for example, the four connecting shaft members 35 can be simultaneously raised and lowered by the jack 43, the compression force can be easily and easily adjusted.
