Description

本発明は、事務所ビル、工場あるいは集合住宅などの建築物の基礎において、免震装置を設置する際に、免震装置のベースプレートの下部に高流動コンクリートまたはグラウト材（モルタル）などの充填材を充填する充填装置に関する。 The present invention provides a filler such as high-fluidity concrete or grout material (mortar) in the lower part of the base plate of the seismic isolation device when the seismic isolation device is installed on the foundation of a building such as an office building, factory or apartment house. It is related with the filling apparatus which fills.

免震装置を据え置く基礎（土台）となる免震基礎の上面に免震装置の下部にベースプレートを設置する作業は以下のように行われている。まず、建築物の床版コンクリートを形成し、床版コンクリート上の所定の位置に型枠を組み立て、型枠内にコンクリートを打設して免震基礎の下部コンクリートを形成する。下部コンクリート上にベースプレートを受ける架台を設置するとともに、免震基礎を補強するはかま筋を組み立てる。ベースプレートは、円形や多角形に形成された厚さ１０ｍｍ〜３０ｍｍ程度の鉄板のような平板である。架台の上部にはベースプレート設置面を形成するための３個以上のベースプレート支持体が設けられており、架台に設けられたベースプレート支持体の上下移動機構を操作してベースプレート支持体の上下位置を調整することによってベースプレート設置面の水平レベルを調整する。架台上部に形成された水平レベル調整後のベースプレート設置面にベースプレートの下面を載置し、ベースプレートの上面が水平面となるように設置する。ベースプレートの中央部には、ベースプレートの上下面に貫通する注入孔が形成されている。
グラウト材のような充填材やコンクリートを、ホッパー及び自動突き棒装置を備えた充填装置を用いて注入孔よりベースプレート下部に注入する。この際、ホッパーの充填材排出口とベースプレートの注入孔とが合うようにベースプレートの上面に充填装置が設置される。まず、コンクリートがホッパー内からホッパーの充填材排出口及びベースプレートの注入孔を経由して型枠で囲まれたベースプレート下に打設されることによって先行コンクリートが形成される。この際、先行コンクリートの天端がベースプレートの下面より下方に約３０ｍｍ〜５０ｍｍ程度の位置まで来るようにする。即ち、先行コンクリートの天端とベースプレートの下面との間に約３０ｍｍ〜５０ｍｍ程度の充填用空間が形成される。そして、充填材がホッパー内からホッパーの充填材排出口及びベースプレートの注入孔を経由して充填用空間内に打設供給されて上端部充填材層が形成される（例えば、特許文献１等参照）。 The work of installing the base plate at the bottom of the seismic isolation device on the upper surface of the base is to be the base (base) on which the seismic isolation device is installed. First, floor slab concrete of a building is formed, a formwork is assembled at a predetermined position on the floor slab concrete, and concrete is placed in the formwork to form the lower concrete of the seismic isolation foundation. A base for receiving the base plate will be installed on the lower concrete, and a hoop will be assembled to reinforce the base for seismic isolation. The base plate is a flat plate such as an iron plate having a thickness of about 10 mm to 30 mm formed in a circular or polygonal shape. Three or more base plate supports for forming the base plate installation surface are provided on the top of the base, and the vertical position of the base plate support is adjusted by operating the vertical movement mechanism of the base plate support provided on the base. To adjust the horizontal level of the base plate installation surface. The lower surface of the base plate is placed on the base plate installation surface after the horizontal level adjustment formed on the gantry, and the upper surface of the base plate is installed so as to be a horizontal plane. An injection hole penetrating the upper and lower surfaces of the base plate is formed at the center of the base plate.
A filler such as a grout material or concrete is poured into the lower portion of the base plate through a filling hole using a filling device having a hopper and an automatic thrusting device. At this time, the filling device is installed on the upper surface of the base plate so that the filler discharge port of the hopper and the injection hole of the base plate are aligned. First, prior concrete is formed by placing concrete from the inside of the hopper through the filler discharge port of the hopper and the injection hole of the base plate and under the base plate surrounded by the formwork. At this time, the top end of the preceding concrete is made to come to a position of about 30 mm to 50 mm below the lower surface of the base plate. That is, a filling space of about 30 mm to 50 mm is formed between the top end of the preceding concrete and the lower surface of the base plate. Then, the filler is driven and supplied from the hopper through the filler discharge port of the hopper and the injection hole of the base plate into the filling space to form an upper end filler layer (see, for example, Patent Document 1). ).

従来の免震装置のベースプレート下部への充填材の充填方法によれば、充填装置の自重及び充填材の重量をベースプレートで支持した状態で充填工事を行うため、ベースプレートには、おおよそ、充填装置の自重１００ｋｇ〜１５０ｋｇと充填材の重量３００ｋｇ〜５００ｋｇとが加わり、ベースプレートが撓んだ状態で充填作業を行うこととなる。充填作業は、ベースプレートの下面、具体的にはベースプレートの注入孔の上端まで充填材が満たされた状態で終了するが、上述のようにベースプレートが撓んだ状態で充填作業を行った場合、その後、充填装置をベースプレート上から撤去することに伴いベースプレートは弾性により復元する。これに起因して、ベースプレートの下面と充填材とが互いに接触した状態から両者の縁が切れて空隙が形成され、または空隙が形成されるおそれがあった。このため、空隙の形成防止のために少しでも充填装置を軽量化することが望まれていた。この場合、例えば、薄板の金属板を用いて肉厚の薄いホッパーを形成することで充填装置の軽量化を図ることが考えられる。
また、充填作業は、例えば、ホッパー内に１つの充填箇所の体積よりも多い充填材を貯留した後に充填装置を複数の充填箇所に移動して行うが、この場合、吊りフックを溶接などによってホッパーに直接に取付け、この吊りフックをクレーン等で吊って充填装置を移動することが考えられる。
しかしながら、軽量化のために肉厚を薄くしたホッパーに吊りフックを溶接などによって直接に取付けて、この吊りフックをクレーン等で吊ると、ホッパー内に充填材が残っている場合には、吊りフックとホッパーとの接続部に充填装置の自重と充填材の重量とが加わるので、吊りフックとホッパーとの接続部において薄肉のホッパーが変形したり破壊したりしてしまうという問題点があった。
本発明は上記問題点に鑑みてなされたもので、吊りフックを備えるとともにホッパーの変形などを防止できてかつ軽量化が図れる充填装置を提供する。 According to the conventional method of filling the base material with the base material, the base plate is filled with the weight of the filling device and the weight of the filling material supported by the base plate. The weight of 100 kg to 150 kg and the weight of the filler of 300 kg to 500 kg are added, and the filling operation is performed in a state where the base plate is bent. The filling operation is completed with the filling material filled up to the lower surface of the base plate, specifically, the upper end of the injection hole of the base plate, but if the filling operation is performed with the base plate bent as described above, As the filling device is removed from the base plate, the base plate is restored by elasticity. Due to this, there is a possibility that the edges of the base plate and the filler are cut from each other and the edges thereof are cut to form voids, or voids are formed. For this reason, it has been desired to reduce the weight of the filling device as little as possible in order to prevent the formation of voids. In this case, for example, it is conceivable to reduce the weight of the filling device by forming a thin hopper using a thin metal plate.
In addition, the filling operation is performed by, for example, storing the filling material larger than the volume of one filling place in the hopper and then moving the filling device to a plurality of filling places. It is conceivable that the filling device is moved by attaching the suspension hook directly with a crane or the like.
However, if the suspension hook is attached directly to the hopper with a thin wall thickness for weight reduction by welding or the like, and this suspension hook is suspended by a crane or the like, if the filler remains in the hopper, the suspension hook Since the weight of the filling device and the weight of the filler are added to the connecting portion between the hopper and the hopper, there is a problem that the thin hopper is deformed or broken at the connecting portion between the hanging hook and the hopper.
The present invention has been made in view of the above problems, and provides a filling device that includes a hanging hook, can prevent deformation of the hopper, and can be reduced in weight.

本発明に係る充填装置によれば、免震基礎を構築するに際し、ベースプレートに設けた注入孔からベースプレートの下方に充填材を充填するための充填装置であって、ホッパーと、開閉手段と、吊り部取付部と、吊り部とを備え、ホッパーは、上部開口を有して上部開口を介して投入された充填材を貯留する筒状の貯留部と、貯留部に貯留された充填材を排出するための充填材排出口とを備え、開閉手段が充填材排出口を開閉可能なように設けられ、吊り部取付部が貯留部の上部開口側に設けられ、吊り部が吊り部取付部に取付けられており、かつ、吊り部取付部が２本以上の支柱により形成され、支柱は、ホッパーの中心線に沿って延長するようにホッパーの外周面に取付けられ、上端部に吊り部が取付けられ、下端がベースプレート上に載置されるので、吊りフックを備えるとともにホッパーの変形などを防止できてかつ軽量化を図ることができるとともに、支柱が補強部材として機能し、吊りフックとホッパーとが直接的に溶接などで取付けられている場合に比べて、吊りフックからホッパーに力が伝達されにくくなるため、ホッパーの変形などが抑止され、また、ホッパーの薄肉化による軽量化も図ることができるようになる。また、ベースプレート上にホッパーを安定に自立させることができる。
支柱の下部同士を連結してホッパーの貯留部下部の変形を防止する下部変形防止部を備えたので、ホッパーの下部側の変形を防ぐことができる。
ホッパーの貯留部の上部開口側に、当該貯留部上部の変形を防止するための上部変形防止部を備えたので、ホッパーの上部開口側の変形を防ぐことができる。

互いに上下に対応するように位置された上板２３の下面における一方の一対の側縁側の面と下板２４の上面における一方の一対の側縁側の面との間に上記貫通孔２７；２９を避けるようにそれぞれ側板２５；２５が挟み込まれた状態で、上板２３と側板２５と下板２４とがボルト及びナットや溶接などの固定手段３１により接続されたことにより、上板２３と下板２４との間にシャッター板貫通部３５を備えたシャッターボックス２１が形成される。これにより、小径円筒部１８の中心と連通部材４の充填材供給路４ａを形成する筒の中心とが一致する。
即ち、シャッターボックス２１は、互いに対向する他方の一対の側縁面間を貫通するシャッター板貫通部３５が、上記側板２５の設けられていない部分により形成される。貫通孔２７，２９の径寸法以上に離間して互いに平行に対向するように配置された一対の側板２５の対峙する側の側面間の距離により決まるシャッター板貫通部３５の幅寸法は、シャッター板２２がシャッター板貫通部３５内を移動可能となるように、シャッター板２２の幅（短手方向の幅）とほぼ同じ寸法となるように決定される。
シャッター板２２は、長手方向の長さがシャッターボックス２１のシャッター板貫通部３５の長さ寸法の２倍程度の長さの矩形板材により形成される。シャッター板２２は、長手方向の端部に貫通孔３６を備える。小径円筒部１８及び連通部材４の充填材供給路４ａの中心とシャッター板２２の貫通孔３６の中心とが一致した場合に、小径円筒部１８の下端開口部１７の内径とシャッター板２２の貫通孔３６の内径と連通部材４の充填材供給路４ａの内径とが同径となる。シャッター板２２の長手方向の両端には、シャッターボックス２１のシャッター板貫通部３５の両端開口部周りの側面に係止するストッパ３７が設けられる。例えば、シャッター板２２の長手方向の一端に設けられたストッパ３７がシャッターボックス２１のシャッター板貫通部３５の一端開口部周りの一側面２１ａに係止した状態でシャッター板２２の貫通孔３６の中心と小径円筒部１８の中心とが一致し、シャッター板２２の長手方向の他端に設けられたストッパ３７がシャッターボックス２１のシャッター板貫通部３５の他端開口部周りの他側面２１ｂに係止した状態で小径円筒部１８の下端開口部１７がシャッター板２２により塞がれる。 As shown in FIG. 2; FIG. 5, the opening / closing means 3 provided under the small diameter cylindrical portion 18 includes a shutter box 21 and a shutter plate 22.

And the lower end opening part 17 of the small diameter cylindrical part 18 is connected with the periphery of the through-hole 27 of the upper surface of the upper board 23 by welding. Alternatively, the lower end opening 17 of the small diameter cylindrical portion 18 is fitted into the through hole 27 of the upper plate 23, and the lower end opening end surface of the small diameter cylindrical portion 18 does not protrude from the lower surface of the upper plate 23. The upper plate 23 is connected by welding or the like.
The lower plate 24 is formed of a metal rectangular flat plate having a through hole 29 at the center.

The through hole 29 is formed to have the same inner peripheral diameter, or the outer peripheral diameter of the upper end opening 30 of the communication member 4 and the inner peripheral diameter of the through hole 29 of the lower plate 24 are matched. Is done. The upper end opening 30 of the communication member 4 is connected to the periphery of the through hole 29 on the lower surface of the lower plate 24 by welding or the like. Alternatively, the communication member 4 and the lower plate 24 are arranged so that the upper end opening 30 of the communication member 4 is fitted into the through hole 29 of the lower plate 24 and the upper end opening end surface of the communication member 4 does not protrude from the upper surface of the lower plate 24. And are connected by welding or the like.
The through holes 27; 29 are provided between one pair of side edge surfaces on the lower surface of the upper plate 23 and the one pair of side edge surfaces on the upper surface of the lower plate 24, which are positioned so as to correspond to each other vertically. The upper plate 23, the side plate 25, and the lower plate 24 are connected to each other by a fixing means 31 such as a bolt, a nut, or welding in a state where the side plates 25; 25 are sandwiched between the upper plate 23 and the lower plate. A shutter box 21 having a shutter plate penetrating portion 35 is formed between them. Thereby, the center of the small diameter cylindrical part 18 and the center of the cylinder which forms the filler supply path 4a of the communicating member 4 coincide.
That is, in the shutter box 21, a shutter plate penetrating portion 35 penetrating between the other pair of side edge surfaces facing each other is formed by a portion where the side plate 25 is not provided. The width dimension of the shutter plate penetrating portion 35 determined by the distance between the side surfaces facing each other of the pair of side plates 25 arranged so as to be opposed to each other in parallel with a distance larger than the diameter dimension of the through holes 27 and 29 is the shutter plate. The width of the shutter plate 22 is determined to be approximately the same as the width of the shutter plate 22 (the width in the short direction) so that 22 can move in the shutter plate penetrating portion 35.
The shutter plate 22 is formed of a rectangular plate material whose length in the longitudinal direction is about twice the length of the shutter plate penetrating portion 35 of the shutter box 21. The shutter plate 22 includes a through hole 36 at an end portion in the longitudinal direction. When the center of the small-diameter cylindrical portion 18 and the filler supply path 4a of the communication member 4 and the center of the through hole 36 of the shutter plate 22 coincide with each other, the inner diameter of the lower end opening 17 of the small-diameter cylindrical portion 18 and the shutter plate 22 penetrate.

And a disk-shaped face plate 45 that is positioned in parallel with the disk. The face plate includes a through hole 45a at the center. For example, the communication member 4 is formed such that the outer peripheral diameter of the lower end opening 41 of the cylindrical portion 40 is larger than the inner peripheral diameter of the through hole 45 a of the face plate 45, and the inner peripheral diameter of the cylindrical portion 40 and the inner peripheral diameter of the face plate 45. Are formed to have the same diameter, or the outer peripheral diameter of the lower end opening 41 of the communication member 4 and the inner peripheral diameter of the through hole 45a of the face plate 45 are matched. The lower end opening 41 of the communication member 4 is connected to the periphery of the through hole 45a on the upper surface of the face plate 45 by welding or the like. Alternatively, the communication member 4 and the face plate 45 are welded or the like so that the lower end opening 41 of the communication member 4 is fitted into the through hole of the face plate 45 and the lower end opening end face of the communication member 4 does not protrude from the lower surface of the face plate 45. Connected.

漏れ防止材５は、例えば、ゴムのような弾性体により形成される。漏れ防止材５は、充填材１０を充填材供給路４ａの下端開口４１から注入孔９３に導くガイド孔４２を備え、ベースプレート９０に後述する支柱６が載置されてベースプレート９０上にホッパー２が自立した状態において、充填装置１の荷重によってベースプレート９０の上面９１と面板４５の下面４６との間に圧縮された状態となる。ガイド孔４２は、圧縮時において、連通部材４の充填材供給路４ａの内径、及び、注入孔９３の内径と同径となる寸法に形成される。
例えば、後述する４本の支柱６の下端面５０がベースプレート９０の上面９１に設置されてホッパー２が自立された状態において、上記連通部材４の面板４５の下面４６とベースプレート９０の間に例えば１０ｍｍ以内の隙間が形成されるように４本の支柱６の長さを決める。そして、例えば、当該隙間に隙間の寸法よりも厚い寸法の弾性体シート５１を、ベースプレート９０上に載置した後、または、上記連通部材４の面板４５の下面４６に取付けておいた後に、後述する４本の支柱６の下端面５０をベースプレート９０の上面９１に設置してホッパー２を自立させる。このようにすれば、ホッパー２及び充填材１０の重量によって、充填材供給路４ａとガイド孔４２と注入孔９３とが連通するとともに、充填材供給路４ａを形成する連通部材４の下端面と漏れ防止材５とが密着し、かつ、ベースプレート９０の注入孔９３周りの上面９１と漏れ防止材５とが密着するので、充填材１０がベースプレート９０の上面９１に漏れることなく、充填用空間６９に充填される。 The leak prevention material 5 is formed of an elastic body such as rubber, for example. The leakage preventing material 5 includes a guide hole 42 that guides the filler 10 from the lower end opening 41 of the filler supply path 4 a to the injection hole 93, and a support 6 described later is placed on the base plate 90, and the hopper 2 is placed on the base plate 90. In the self-standing state, the state is compressed between the upper surface 91 of the base plate 90 and the lower surface 46 of the face plate 45 by the load of the filling device 1. The guide hole 42 is formed to have the same diameter as the inner diameter of the filler supply passage 4 a of the communication member 4 and the inner diameter of the injection hole 93 during compression.
For example, in a state where the lower end surfaces 50 of four columns 6 to be described later are installed on the upper surface 91 of the base plate 90 and the hopper 2 is self-supporting, it is, for example, 10 mm between the lower surface 46 of the face plate 45 of the communication member 4 and the base plate 90. The lengths of the four struts 6 are determined so as to form a gap of within. Then, for example, after the elastic body sheet 51 having a thickness larger than the size of the gap is placed on the base plate 90 or attached to the lower surface 46 of the face plate 45 of the communication member 4, it will be described later. The lower end surfaces 50 of the four struts 6 are installed on the upper surface 91 of the base plate 90 so that the hopper 2 is self-supporting. If it does in this way, with the weight of the hopper 2 and the filler 10, the filler supply path 4a, the guide hole 42, and the injection hole 93 communicate with each other, and the lower end surface of the communication member 4 that forms the filler supply path 4a Since the leakage preventing material 5 is in close contact with each other, and the upper surface 91 around the injection hole 93 of the base plate 90 and the leakage preventing material 5 are in close contact, the filling material 69 does not leak into the upper surface 91 of the base plate 90. Filled.

支柱６は、ホッパー２の中心線Ｏに沿って延長するようにホッパー２の外周面５３に溶接などの固定手段により取付けられ、下端面５０がベースプレート９０上に載置されることでホッパー２を自立させるものであるとともに、後述する吊り部７としての吊りフックを設けるための吊り部取付部として機能する。
例えば、支柱６は、ホッパー２の貯留部９の外周面５３に４本設けられる。図３に示すように、４本の支柱６は、ホッパー２の中心線Ｏと直交する第１の直線Ｌ１と交差する貯留部９の外周面５３の２点に設置される一方の一対の２つの支柱６Ａ；６Ｂと、当該第１の直線と直交する第２の直線Ｌ２と交差する貯留部９の外周面５３の２点に設置される他方の一対の２つの支柱６Ｃ；６Ｄとを備える。即ち、ホッパー２の中心線Ｏを中心とする円の周方向に各々９０度隔てて隣り合うようにホッパー２の外周面５３と４本の支柱６Ａ；６Ｂ；６Ｃ；６Ｄとが溶接により連結される。支柱６は、例えば、鉄製の断面形状Ｌ字型のアングル材により形成され、断面形状Ｌ字型のアングル材のＬ字の両端をホッパー２の外周面５３に接触させて、アングル材のＬ字の両端とホッパー２とが溶接により連結される。 The column 6 is attached to the outer peripheral surface 53 of the hopper 2 by a fixing means such as welding so as to extend along the center line O of the hopper 2, and the lower end surface 50 is placed on the base plate 90 so that the hopper 2 is mounted. In addition to being self-supporting, it functions as a hanging portion attaching portion for providing a hanging hook as a hanging portion 7 described later.
For example, four struts 6 are provided on the outer peripheral surface 53 of the storage portion 9 of the hopper 2. As shown in FIG. 3, the four struts 6 are one pair of two installed at two points on the outer peripheral surface 53 of the storage portion 9 that intersects the first straight line L <b> 1 orthogonal to the center line O of the hopper 2. One support column 6A; 6B, and the other pair of two support columns 6C; 6D installed at two points on the outer peripheral surface 53 of the storage section 9 intersecting the second straight line L2 orthogonal to the first straight line. . That is, the outer peripheral surface 53 of the hopper 2 and the four struts 6A; 6B; 6C; 6D are connected by welding so as to be adjacent to each other by 90 degrees in the circumferential direction of the circle centered on the center line O of the hopper 2. The The strut 6 is made of, for example, an iron-shaped L-shaped angle material, and both ends of the L-shaped angle material of the cross-sectional shape are brought into contact with the outer peripheral surface 53 of the hopper 2 to form an L-shaped angle material. Both ends of the hopper 2 and the hopper 2 are connected by welding.

吊り部７は、Ｕ字状の鋼棒により形成された吊りフック５４により構成される。吊りフック５４のＵ字の両端部５４ａ；５４ａと支柱６の上端部とが溶接により連結される（図４（ａ），（ｂ）参照）。 The hanging part 7 is constituted by a hanging hook 54 formed of a U-shaped steel rod. The U-shaped end portions 54a; 54a of the suspension hook 54 and the upper end portion of the support 6 are connected by welding (see FIGS. 4A and 4B).

このように、吊りフック５４が支柱６の上部に取付けられたことで、支柱６が補強部材として機能し、吊りフック５４とホッパー２とが直接的に溶接などで取付けられている場合に比べて、吊りフック５４からホッパー２に力が伝達されにくくなるため、ホッパー２の変形などが抑止され、また、ホッパー２の薄肉化による軽量化も図ることができるようになる。 As described above, the suspension hook 54 is attached to the upper portion of the support column 6, so that the support column 6 functions as a reinforcing member, compared to a case where the suspension hook 54 and the hopper 2 are directly attached by welding or the like. Since it becomes difficult for force to be transmitted from the suspension hook 54 to the hopper 2, deformation of the hopper 2 and the like are suppressed, and weight reduction by thinning the hopper 2 can be achieved.

ホッパー２の貯留部９の上部開口８側には、当該貯留部９上部の変形を防止するための上部変形防止部５５を備える。 On the upper opening 8 side of the storage part 9 of the hopper 2, an upper deformation prevention part 55 for preventing deformation of the upper part of the storage part 9 is provided.

上部変形防止部５５は、ホッパー２、または、支柱６に形成される。
上部変形防止部５５がホッパー２に形成される場合、上部変形防止部５５は、ホッパー２の内周面５２の同一水平面上の離間した２点以上を繋ぐ板材により形成される。例えば、ホッパー２の中心線Ｏと直交する第１の直線Ｌ１に沿って設置される一方の板材Ｂ１と、当該第１の直線と直交する第２の直線Ｌ２に沿って設置される他方の板材Ｂ２とが結合された平面視十字形の連結板材５５ａが大径円筒部１２の内周面の上端部に設置される。
上部変形防止部５５が支柱６に形成される場合、上部変形防止部５５は、互いに隣り合う支柱６同士を繋ぐ板材により形成される。例えば、ホッパー２の上部開口８を跨ぐように平面視十字形の連結板材５５ａの４つの端部を互いに隣り合う４本の支柱の上端部と連結したり、互いに隣り合う支柱６の上端部同士を繋いで四角枠形状に形成したり、互いに隣り合う支柱６の上端部同士を取り囲むように四角枠形状に形成すればよい。
連結板材５５ａ及び板材としては鉄製の断面Ｌ字型のアングル材を用いる。連結板材５５ａ及び板材とホッパー２とは溶接により連結される。また、連結板材５５ａと支柱６とは溶接により連結される。 The upper deformation prevention unit 55 is formed on the hopper 2 or the support column 6.
When the upper deformation prevention part 55 is formed in the hopper 2, the upper deformation prevention part 55 is formed by a plate material that connects two or more spaced apart points on the same horizontal plane of the inner peripheral surface 52 of the hopper 2. For example, one plate material B1 installed along the first straight line L1 orthogonal to the center line O of the hopper 2 and the other plate material installed along the second straight line L2 orthogonal to the first straight line. A connecting plate member 55a having a cross shape in plan view coupled with B2 is installed at the upper end portion of the inner peripheral surface of the large-diameter cylindrical portion 12.
When the upper deformation prevention part 55 is formed on the support column 6, the upper deformation prevention part 55 is formed by a plate material that connects the adjacent support columns 6 to each other. For example, the four end portions of the connecting plate member 55a having a cross shape in plan view so as to straddle the upper opening 8 of the hopper 2 are connected to the upper end portions of four struts adjacent to each other, or the upper end portions of the struts 6 adjacent to each other are connected to each other. May be formed in a square frame shape, or may be formed in a square frame shape so as to surround the upper ends of the columns 6 adjacent to each other.
As the connecting plate member 55a and the plate member, an iron-made angle member having an L-shaped cross section is used. The connecting plate material 55a and the plate material and the hopper 2 are connected by welding. Further, the connecting plate material 55a and the column 6 are connected by welding.

上部変形防止部５５が設けられたことにより、充填材１０が充填された充填装置１のホッパー２が吊り上げられる際に、ホッパー２の上部開口８側の変形を防ぐことができる。 By providing the upper deformation prevention part 55, when the hopper 2 of the filling device 1 filled with the filler 10 is lifted, deformation of the hopper 2 on the upper opening 8 side can be prevented.

下部変形防止部５６は、ホッパー２の貯留部９下部の変形を防止する。下部変形防止部５６は、例えば、上記４本の支柱６Ａ；６Ｂ；６Ｃ；６Ｄの下部同士を取り囲むように上記４本の支柱が連結材５７で連結されたことにより形成される。
下部変形防止部５６が設けられたことにより、ホッパー２の下部側の変形を防ぐことができる。 The lower deformation prevention part 56 prevents the deformation of the lower part of the storage part 9 of the hopper 2. The lower deformation prevention part 56 is formed, for example, by connecting the four struts with a connecting member 57 so as to surround the lower portions of the four struts 6A; 6B; 6C; 6D.
By providing the lower deformation preventing part 56, it is possible to prevent the lower side of the hopper 2 from being deformed.

充填装置１は、例えば、充填装置１の縦幅（支柱の縦幅）Ｈ＝１２６０ｍｍ、充填装置１の横幅Ｗ＝５８０ｍｍ、ホッパー２の縦幅１２００ｍｍ、ホッパー２の横幅５８０ｍｍ、円錐状筒壁部１５の縦幅４００ｍｍ、大径円筒部１２の縦幅７７０ｍｍ、シャッターボックス２１の縦幅１８ｍｍ（上板２３の縦幅、下板２４の縦幅、側板２５の縦幅各６ｍｍ）、筒部４０の縦幅３０ｍｍ、面板４５の縦幅６ｍｍ、ベースプレート９０に支柱６が載置されてベースプレート９０上にホッパー２が自立した状態の面板４５の裏面とベースプレート９０との間隔６ｍｍ、大径円筒部１２及び円錐状筒壁部１５の厚みは２．３ｍｍ、ホッパーの重量７１ｋｇ、ホッパーの容量２２０リットルである。ホッパー２は、充填用空間６９の容積よりも大きい容積を有したホッパー２を用いる。 The filling device 1 includes, for example, the vertical width (vertical width) of the filling device 1 = 1260 mm, the horizontal width W = 580 mm of the filling device 1, the vertical width of the hopper 2, 1200 mm, the horizontal width of the hopper 2 580 mm, and a conical cylindrical wall portion 15 vertical width of 400 mm, vertical diameter of large diameter cylindrical portion 12 770 mm, vertical width of shutter box 21 (vertical width of upper plate 23, vertical width of lower plate 24, vertical width of side plate 25 each 6 mm), cylindrical portion 40 30 mm in length, 6 mm in length of the face plate 45, 6 mm between the back surface of the face plate 45 and the base plate 90 with the support 6 placed on the base plate 90 and the hopper 2 standing on the base plate 90, the large-diameter cylindrical portion 12 The thickness of the conical cylindrical wall portion 15 is 2.3 mm, the weight of the hopper is 71 kg, and the capacity of the hopper is 220 liters. As the hopper 2, the hopper 2 having a volume larger than the volume of the filling space 69 is used.

充填装置１を用いた免震装置のベースプレート９０下部への充填材１０の充填方法を説明する。
まず、例えば、ベースプレート９０の注入孔９３の中心と弾性体シート５１のガイド孔４２の中心とが一致するように漏れ防止材５をベースプレート９０に設置する。次に、図外のクレーン等の揚重機により、充填装置１の各支柱６Ａ；６Ｂ；６Ｃ；６Ｄに設置された吊りフック５４に図外のワイヤーを係止してワイヤーを図外のクレーン等の揚重機により吊ることで充填装置１を吊り上げる。
次に、充填装置１の連通部材４の充填材供給路４ａの中心とガイド孔４２の中心とを一致させて支柱６をベースプレート９０に設置する。この場合、連通部材４の面板４５の面積と漏れ防止材５の面積とが同じであれば、漏れ防止材５を目標にして連通部材４の面板４５を位置合わせすることで、ホッパー２の充填材排出口１１の中心とベースプレート９０の注入孔９３の中心とを一致させることができるので、充填装置１をベースプレート９０に容易に位置決めできる。
そして、貯留部９に充填材１０を投入して、開閉手段３を開いて充填材１０を充填用空間６９に充填する。この場合、ホッパー２及び充填材１０の重量によって、充填材供給路４ａとガイド孔４２と注入孔９３とが連通するとともに、充填材供給路４ａを形成する連通部材４の下端面と漏れ防止材５とが密着し、かつ、ベースプレート９０の注入孔９３周りの上面９１と漏れ防止材５とが密着するので、充填材１０がベースプレート９０の上面９１に漏れることなく、充填用空間６９に充填される。 A method of filling the filler 10 into the lower portion of the base plate 90 of the seismic isolation device using the filling device 1 will be described.
First, for example, the leakage preventing material 5 is installed in the base plate 90 so that the center of the injection hole 93 of the base plate 90 and the center of the guide hole 42 of the elastic sheet 51 coincide. Next, an unillustrated crane or the like lifts a wire outside the figure to the suspension hook 54 installed on each column 6A; 6B; 6C; The filling device 1 is lifted by being hung by a lifting machine.
Next, the column 6 is installed on the base plate 90 so that the center of the filler supply path 4 a of the communication member 4 of the filling device 1 is aligned with the center of the guide hole 42. In this case, if the area of the face plate 45 of the communication member 4 and the area of the leakage preventing material 5 are the same, the filling of the hopper 2 can be achieved by aligning the face plate 45 of the communication member 4 with the leakage preventing material 5 as a target. Since the center of the material discharge port 11 and the center of the injection hole 93 of the base plate 90 can be matched, the filling device 1 can be easily positioned on the base plate 90.
Then, the filler 10 is put into the storage portion 9, the opening / closing means 3 is opened, and the filler 10 is filled in the filling space 69. In this case, the filler supply path 4a, the guide hole 42, and the injection hole 93 communicate with each other by the weight of the hopper 2 and the filler 10, and the lower end surface of the communication member 4 that forms the filler supply path 4a and the leakage preventing material. 5 and the upper surface 91 around the injection hole 93 of the base plate 90 and the leakage preventing material 5 are in close contact with each other, so that the filler 10 is filled in the filling space 69 without leaking to the upper surface 91 of the base plate 90. The

本実施形態によれば、支柱６に設置された吊りフック５４を備えたことにより、クレーンが吊りフック５４と直接連結された支柱６を吊り上げるので、吊りフック５４からホッパー２に力が伝達されにくくなるため、ホッパー２の変形などが抑止され、また、ホッパー２の薄肉化による軽量化も図ることができるようになる。 According to the present embodiment, the suspension hook 54 installed on the support 6 is provided, so that the crane lifts the support 6 directly connected to the suspension hook 54, so that force is not easily transmitted from the suspension hook 54 to the hopper 2. Therefore, deformation of the hopper 2 and the like are suppressed, and weight reduction due to thinning of the hopper 2 can be achieved.

本実施形態によれば、上部変形防止部５５を備えたので、ホッパー２の上部開口８側の変形を防ぐことができる。 According to the present embodiment, since the upper deformation preventing portion 55 is provided, deformation of the hopper 2 on the upper opening 8 side can be prevented.

本実施形態によれば、下部変形防止部５６を備えたので、ホッパー２の下部側の変形を防ぐことができる。 According to this embodiment, since the lower deformation prevention part 56 is provided, the deformation | transformation of the lower part side of the hopper 2 can be prevented.

本実施形態によれば、筒部４０の下端開口４１の周囲に設けられた面板４５とベースプレート９０の上面９１との間に漏れ防止材５を備えたので、充填材１０がベースプレート９０の上面９１に漏れることなく、充填用空間６９に充填される。 According to the present embodiment, since the leakage preventing material 5 is provided between the face plate 45 provided around the lower end opening 41 of the cylindrical portion 40 and the upper surface 91 of the base plate 90, the filler 10 serves as the upper surface 91 of the base plate 90. The filling space 69 is filled without leaking.

本実施形態によれば、４本の支柱６を備えたので、ベースプレート９０上にホッパー２を安定に自立させることができ、作業性を向上できる。 According to the present embodiment, since the four struts 6 are provided, the hopper 2 can be stably made independent on the base plate 90, and workability can be improved.

本実施形態によれば、ホッパー２内に充填材１０を貯留するための開閉手段３を備えたので、シャッターボックス２１のシャッター板２２により小径円筒部１８の下端開口部１７が塞がれた場合、ホッパー２内に一定量の充填材１０を一時貯留するので、ホッパー２内への投入時またはポンプによる圧送時に充填材１０中に巻き込んだ空気（気泡）を脱気でき、ベースプレート９０の下面９２と充填用空間６９に充填される充填材１０との境界に空気溜まりが生じにくくなり、ベースプレート９０の下面９２と充填材１０との密着性が保たれた高品質の免震基礎を提供できるようになる。また、開閉手段３のシャッター板２２が漏れ防止材５及び連通部材４を介してベースプレート９０よりも高い位置に設けられているため、シャッター板２２が開いた場合、ホッパー２内に貯留されていた充填材１０の高さ位置に応じた圧力が、排出圧力となって充填材１０に加わるので、充填材１０が充填材供給路４ａの下端開口４１よりスムーズに排出されるようになって、充填作業時間を短くでき、作業性が向上する。 According to the present embodiment, since the opening / closing means 3 for storing the filler 10 in the hopper 2 is provided, the lower end opening 17 of the small-diameter cylindrical portion 18 is blocked by the shutter plate 22 of the shutter box 21. Since a certain amount of filler 10 is temporarily stored in the hopper 2, air (bubbles) entrained in the filler 10 can be degassed when being charged into the hopper 2 or pumped by a pump, and the lower surface 92 of the base plate 90. Therefore, it is possible to provide a high-quality seismic isolation base in which air accumulation is less likely to occur at the boundary between the filler 10 filled in the filling space 69 and adhesion between the lower surface 92 of the base plate 90 and the filler 10 is maintained. become. Further, since the shutter plate 22 of the opening / closing means 3 is provided at a position higher than the base plate 90 via the leakage prevention member 5 and the communication member 4, the shutter plate 22 is stored in the hopper 2 when the shutter plate 22 is opened. Since the pressure corresponding to the height position of the filler 10 becomes a discharge pressure and is applied to the filler 10, the filler 10 is smoothly discharged from the lower end opening 41 of the filler supply path 4 a, and the filling is performed. Work time can be shortened and workability is improved.

本実施形態によれば、ホッパー２の漏斗部１３により、円錐状筒壁部１５から小径円筒部１８に流下する充填材の圧力を大きくする圧力付与部が構成される。即ち、充填材１０の流下する方向に向けて流路径が漸次小さくなるように形成された円錐状筒壁部１５を備えているので、充填材１０が円錐状筒壁部１５の流路径の大きい部分から流路径の漸次小さくなる円錐状筒壁部１５内を経由して流路径の小さい小径円筒部１８内に流下するため、ベルヌーイの法則によって小径円筒部１８内に流下する充填材１０の圧力が増し、充填材排出口１１及び充填材供給路４ａの下端開口４１より落下する充填材１０の落下速度が速くなるため、充填材１０が固化する前の流動性が高い状態でベースプレート９０の充填用空間６９に充填材１０が充填されるので、ベースプレート９０の下面９２と充填材１０との密着性が保たれた高品質の免震基礎を提供できる。 According to this embodiment, the funnel portion 13 of the hopper 2 constitutes a pressure applying portion that increases the pressure of the filler flowing down from the conical cylindrical wall portion 15 to the small diameter cylindrical portion 18. That is, since the conical cylindrical wall portion 15 is formed so that the flow passage diameter gradually decreases in the direction in which the filler 10 flows down, the filler 10 has a large flow passage diameter in the conical cylindrical wall portion 15. The pressure of the filler 10 flowing down into the small-diameter cylindrical portion 18 by Bernoulli's law because it flows into the small-diameter cylindrical portion 18 with a small channel diameter via the inside of the conical cylindrical wall portion 15 from which the channel diameter gradually decreases. Since the falling speed of the filler 10 falling from the filler outlet 11 and the lower end opening 41 of the filler supply passage 4a is increased, the filling of the base plate 90 is performed in a state where the fluidity before the filler 10 is solidified is high. Since the filler material 10 is filled in the working space 69, it is possible to provide a high-quality seismic isolation base in which the adhesion between the lower surface 92 of the base plate 90 and the filler material 10 is maintained.

小径円筒部１８及び連通部材４の充填材供給路４ａの中心とシャッター板２２の貫通孔３６の中心とが一致した場合に、小径円筒部１８の下端開口部１７の内径とシャッター板２２の貫通孔３６の内径と連通部材４の充填材供給路４ａの内径とが同径となるようにしたが、小径円筒部１８の下端開口部１７の内径＜シャッター板２２の貫通孔３６の内径＜連通部材４の充填材供給路４ａの内径とするとともに連通部材４の充填材供給路４ａの内径を注入孔９３の孔径よりも小さく形成してもよい。
これによれば、充填材供給路４ａの内径と注入孔９３の孔径とを同径とした場合に比べて、ベースプレート９０下に落下する充填材１０の落下速度を速くできる。このため、充填材１０が先行上部コンクリート９５ｂの天端９５ｔより上方向に山状に盛り上がるように積み重ねられた後にベースプレート９０の下面９２に接する山ができた後に放射状に周囲に拡がるので、充填材１０が充填用空間６９の空気を押出しながら充填されるため、充填材内への空気の巻き込みを少なくできる。よって、充填用空間６９に対する充填材１０の充填性が向上し、充填材１０が密実に充填されて空気溜まりの少ない上端部充填材層１１０を形成できる。つまり、ベースプレート９０の下面９２と充填用空間６９に充填される充填材との境界に空気溜まりが生じにくくなり、ベースプレート９０の下面９２と充填材１０との密着性が保たれた高品質の免震基礎を提供できる。
一方、連通部材４の充填材供給路４ａの内径と注入孔９３の孔径とを同径とした場合、本実施形態と比べて、ベースプレート９０下部に落下する充填材１０の落下速度が遅くなるので、充填材１０が先行上部コンクリート９５ｂの天端９５ｔより上方向に山状に盛り上がるように積み重なりにくく、先行上部コンクリート９５ｂの天端９５ｔに落下した充填材がすぐに周辺に拡がって面状になり、広い面を形成したままベースプレート９０の下面９２に面接触するため、その下面９２の真下に存在する空気が充填材１０により押出されないまま充填材１０が充填されるので、充填材１０内への空気の巻き込みが多くなる。このため、ベースプレート９０の下面９２と充填用空間６９に充填される充填材１０との境界に空気溜まりが生じやすくなる。 When the center of the small-diameter cylindrical portion 18 and the filler supply path 4a of the communication member 4 and the center of the through hole 36 of the shutter plate 22 coincide with each other, the inner diameter of the lower end opening 17 of the small-diameter cylindrical portion 18 and the shutter plate 22 penetrate. The inner diameter of the hole 36 and the inner diameter of the filler supply passage 4a of the communication member 4 are made the same diameter, but the inner diameter of the lower end opening 17 of the small diameter cylindrical portion 18 <the inner diameter of the through hole 36 of the shutter plate 22 <the communication. The inner diameter of the filler supply path 4 a of the member 4 may be made smaller than the hole diameter of the injection hole 93 while the inner diameter of the filler supply path 4 a of the communication member 4 may be formed.
According to this, compared with the case where the inner diameter of the filler supply path 4a and the hole diameter of the injection hole 93 are made the same diameter, the dropping speed of the filler 10 falling below the base plate 90 can be increased. For this reason, since the filler 10 is stacked so as to rise in a mountain shape upward from the top end 95t of the preceding upper concrete 95b, and then spreads radially around after forming a mountain in contact with the lower surface 92 of the base plate 90, the filler Since 10 is filled while extruding the air in the filling space 69, the entrainment of air into the filler can be reduced. Therefore, the filling property of the filler 10 into the filling space 69 is improved, and the upper filler layer 110 with less air accumulation can be formed by filling the filler 10 densely. In other words, air accumulation is less likely to occur at the boundary between the lower surface 92 of the base plate 90 and the filling material filled in the filling space 69, and high-quality relief can be achieved in which the adhesion between the lower surface 92 of the base plate 90 and the filling material 10 is maintained. Can provide earthquake foundation.
On the other hand, when the inner diameter of the filler supply path 4a of the communication member 4 and the hole diameter of the injection hole 93 are the same, the drop speed of the filler 10 falling to the lower part of the base plate 90 is slower than in the present embodiment. The filler 10 is not easily stacked so as to rise in a mountain shape upward from the top end 95t of the preceding upper concrete 95b, and the filler that has fallen on the top end 95t of the preceding upper concrete 95b immediately spreads to the periphery and becomes planar. Since the wide surface is formed and the lower surface 92 of the base plate 90 is brought into surface contact, the air existing directly below the lower surface 92 is filled with the filler 10 without being pushed out by the filler 10. Increased air entrainment. For this reason, an air reservoir tends to be generated at the boundary between the lower surface 92 of the base plate 90 and the filler 10 filled in the filling space 69.

本実施形態によれば、ホッパー２が上述した圧力付与部を備えるため、小径円筒部１８内に流下する充填材１０の圧力が増し、充填材供給路４ａの下端開口４１より落下する充填材１０の落下速度がさらに速くなるため、充填材１０内への空気の巻き込みをさらに少なくできるので、さらに空気溜まりの少ない上端部充填材層１１０を形成でき、ベースプレート９０の下面９２と充填材１０との密着性が保たれた、より高品質の免震基礎を提供できる。 According to the present embodiment, since the hopper 2 includes the pressure applying portion described above, the pressure of the filler 10 flowing down into the small diameter cylindrical portion 18 increases, and the filler 10 falls from the lower end opening 41 of the filler supply path 4a. Since the falling speed of the gas is further increased, it is possible to further reduce the entrainment of air into the filler 10, so that the upper end filler layer 110 with less air accumulation can be formed, and the lower surface 92 of the base plate 90 and the filler 10 can be formed. Providing a higher quality seismic isolation base with good adhesion.

本実施形態によれば、ホッパー２が、小径円筒部１８を備えたので、角管を用いた場合に比べて、充填材１０が筒内をスムーズに流れるので、充填作業時間を短くでき、作業性が向上する。 According to the present embodiment, since the hopper 2 includes the small-diameter cylindrical portion 18, the filling material 10 flows smoothly in the cylinder as compared with the case where a square tube is used. Improves.

尚、先行コンクリート９５ａ；９５ｂの注入時に使用する充填装置１と、充填材１０の充填時に使用する充填装置１とを別々に用意しておいて、ホッパー２を取り替えることにより、充填材１０と先行コンクリート９５ａ；９５ｂとが混合することを防止できる。
ホッパー２の中心線Ｏを中心とする円の周方向に１２０度隔てた３つの支柱６；６；６を、ホッパー２の外周面５３に設けてもよい。この場合でも、３つの支柱６；６；６によりホッパー２を自立させることができる。
また、吊ることでホッパー２の自立を支援する場合にあっては、ホッパー２の中心線Ｏを中心とする円の周方向に１８０度隔てた２つの支柱６；６を、ホッパー２の外周面５３に設けるだけでもよい。
また、吊り部取付部は、支柱６でなくともよく、ホッパー２の上部開口８側に設けられたホッパー２とは別の補強部材であればよい。 In addition, the filling apparatus 1 used at the time of injection | pouring of the preceding concrete 95a; 95b and the filling apparatus 1 used at the time of filling of the filler 10 are prepared separately, and the filler 10 and the preceding material are replaced by replacing the hopper 2. Mixing with the concrete 95a; 95b can be prevented.

When supporting the independence of the hopper 2 by suspending, the two struts 6; 6 separated by 180 degrees in the circumferential direction of the circle centering on the center line O of the hopper 2 are connected to the outer peripheral surface of the hopper 2. 53 may be provided only.
