Description

【０００１】
【発明の属する技術分野】
本発明は家屋等の建造物を支えるために、束石等を介して鉛直方向に配置され、当該建造物の大引等の基礎材を支持する床束に関する。
【０００２】
例えば木造家屋においては、家屋の床部分を支える架材である大引や根太等と土間との間に床束と称する木材や金属材料からなる支持材を配置することにより家屋の床部分を支える構造となっている。
【０００３】
【従来の技術】
床束により床部を支持する構造では、前記架材である大引や根太の反りや歪み等の木材の経時的変化により、或いは土間の沈下等によって架材側が固定された床束と、床束を支持する束石との間に隙間ができ床束が本来の役目を果たさなくなってしまう事態がしばしば生じている。また、このような固定がなされていない床束の場合には床束自体が倒れてしまう事態も生じている。
【０００４】
【発明が解決しようとする課題】
この様な点に鑑み、床束の一部を螺合構造として、例えばナットを回転させることにより全体の支持高さが調整可能に構成された床束も提供されている。しかし実際には床束の長さ調節は、作業者が床下に入り、多数の床束を個々に高さ調節せねばならず、かつ定期的に床下を見回る必要がある等人手がかかり、実際にはあまり効果的な解決とはなっていない。
【０００５】
発明者らはこのような点に鑑み、床束内にコイルバネ等の弾性体を収納し、この弾性体の弾発力を利用して床束を伸縮可能に構成し、常時床束を架材側に圧接するようにした床束を別途開発している。
【０００６】
この床束は、架材と土間との間隔が変化しても、非常に簡単な構造で当該床束を長期間に渡って架材側に自動的に接触させ、架材を支持することが可能である。反面、土間と架材との間隔の離間の分は全て弾性体の弾発力に依存するため、弾性体の弾発力が強すぎると床部を押し上げる力が働き、また弱すぎると床部を支持できないという点に難点があり、このためこの構成では支持すべき床部の荷重に対応して所定の弾発力を有する弾性体を慎重に選択する必要がある。
【０００７】
なお、特開２００１−５９３３０号にはコイルバネを収納した床束の構成が示されているが、これは螺杆に係止する係止片を斜めに付勢するものであって、架材側の荷重を支持するための弾性体ではなく、床束そのものの高さ調整はやはりボルト・ナットの螺合構造によるものである。即ちこの発明は人手による定期的な床束の高さ調整を行うことを前提とし、かつこの高さ調整作業を容易にすることを目的としている。
【０００８】
【課題を解決するための手段】
本発明は上述の技術的課題を解決するために構成したものであって、床束の高さが自動調整でき、然も高さ自動調整後の架材の支持は弾性体による弾発力ではなく架材を構成する各部材の係合による固定的な支持が可能に構成された床束を提供することを目的としている。
【０００９】
即ち本発明は、主軸と、この主軸に支持され、かつ建築物の架材に当接してこの架材を直接支持する架材支持部とを有し、この架材支持部と主軸との間にはコイルばね等の弾性体が介在配置され、これにより架材支持部は常時架材に当接するよう構成される。また架材支持部と主軸には架材支持部を主軸に係合させる係合手段が設けられ、かつ当該係合手段は、架材支持部が架材側に上昇する事を許容しかつ主軸側に下降するのを阻止するよう構成される。これにより架材側の荷重は前記弾性体を介さず、架材支持部から主軸側に直接伝達されるよう構成したことを特徴とする床束である。
【００１０】
【発明の実施の形態】
架材支持部は架材支持部固定用の係止手段により、内部に収納した弾性体（以下実施例も含めて「コイルばね」を例に説明する）の弾発力に抗して、主軸の頂部に最も近接した状態、即ち主軸側に下降した状態で当該主軸に予め固定されている。
【００１１】
この状態で、床束を家屋等の構造物の床下の所定の位置に配置する。主軸は支持筒側と螺合しており、所定の位置に配置された床束は、ナットを調節することにより支持筒の軸心方向に対して主軸を昇降させ、主軸上端の架材支持部が架材に当接するように高さ調節を行う。
【００１２】
この状態で前記架材支持部固定用の係止手段の係止状態を解除すると、架材支持部はコイルばねの弾発力により架材に対して当接する。なお実施例で詳述するようにコイルばねは架材側の荷重を支持する部材としては機能しないので、その弾発力は架材の下降を阻止する係止手段に抗して架材支持部を上昇させるだけの弾発力を有していればよい。
【００１３】
架材支持部は当該架材支持部の下降阻止係止手段により主軸に対して直接係合するので、架材側の荷重は架材支持部から直接主軸に伝達される。この状態で地盤の沈下等により、地盤と架材との距離が延びると、下降阻止用係止手段は架材支持部が架材側に上昇するのは許容する構成となっているので、前記コイルばねの弾発力により架材支持部はその分架材側に上昇し、架材に対して当接する状態を保持し、架材の荷重を支える。
【００１４】
【実施例】
以下、本発明の実施例を図面を参考に説明する。
図１（Ａ）は本発明の基本構成を示し、（Ｂ）は応用例を示す。なお応用例は床束を上下対象に構成したものであり、（Ａ）は土間（地面）Ｌに接地する側と架材支持部とを別に形成した構成を示す。以下主として（Ａ）の構成を例に説明する。
【００１５】
図１（Ａ）において、矢印１は床束を示す。２はこの床束全体を地盤Ｌ上に立設させるための基台部、３はこの基台部２に嵌挿固定された支持筒である。４は主軸であって、支持筒３の上端に配置されたナット５と螺合することにより支持筒３により支持され、かつナット５を回動調節することにより当該支持筒３の軸心方向に対して昇降可能に構成されている。なお、符号５ａはナット５をロックするロックナットである。
【００１６】
符号６は主軸４に対して取り付けられた架材支持部である。この架材支持部６と主軸４との取り合わせ構造を主として図２を用いて説明する。
架材支持部６は主軸４の上端側が当該架材支持部６内に挿入されるようにして主軸４に取り付けられ、この主軸４により支持される構成となっている。
【００１７】
符号７はコイルばねであって、主軸４の内部空間に一部が収納されると共に、他端は主軸４に嵌挿された架材支持部６に当接し、当該架材支持部６を架材側に当接するよう構成されている。但し、前述の如くコイルばね７自体は架材側の荷重を支持する機能は必要ではなく、あくまでも架材支持部６を架材側に当接するだけであるため、弾発力もその目的を達成する程度で十分であり、従ってこの架材支持部によって架材が上方に押し上げられる等の事態は生じない。
【００１８】
前記架材支持部６と、主軸４との間には、床束１全体を取り付ける際に、架材支持部６を主軸４側に固定する固定手段（以下「架材支持部固定手段」とする）と、床束による架材の支持を行う際に架材支持部６を架材側に当接しかつ架材支持部４の下降を阻止する係止手段（以下「架材支持部保持手段」とする）が形成されている。
【００１９】
先ず架材支持部保持手段について説明する。図２において８Ａ、８Ｂは係止爪部であって、架材支持部保持手段の一部をなす架材支持部６側の構成である。なお図示の構成ではこの係止爪部は図５の符号８Ｃ、８Ｄで示すように、架材支持部６の側壁円周方向に合計４か所形成されている。
【００２０】
一方、主軸４側には前記係止爪部８Ａ乃至８Ｄに対応する係止段部９Ａ乃至９Ｄが形成されている（図２及び図５参照）。この係止段部９Ａ乃至９Ｄは図４（Ａ）及び（Ｂ）に示されるように水平部９Ａａと、この水平部９Ａａからオーバーハング状に上方に展出している斜行部９Ａｂの連続として構成されている。
【００２１】
一方架材支持部６側の係止爪部８Ａの下端部には前記係止段部９Ａの水平部９Ａａと係合する水平部８Ａａと、係止段部９Ａの斜行部９Ａｂと接触摺動する斜行部８Ａｂが形成されている。また、架材支持部６の全体或いは少なくともこの係止爪部８の形成部分は、例えば塩化ビニル等ある程度可撓性を有する材料により構成されている。これにより、床束１と架材とが離間する方向に変位したとき、この変位量に対応して内部のコイルばね７の弾発力に対応して、架材支持部６が上昇し、この上昇に対応して係止爪部８Ａはその可撓性により符号８Ａ´の如く外側に撓みながら斜行部８Ａｂが係止段部９Ａの斜行部９Ａｂ接触摺動しながら上昇し、両斜行部８Ａｂと９Ａｂとの接触状態が解除された時点で係止爪部８Ａの水平部８Ａａは一段上の係止段部の水平部９Ａａに自己の復元力により位置し、架材支持部６と主軸４は再度直接に係合し、架材側の荷重は主軸４側に伝達される。この動作を離間距離の増加に対応して繰り返すことにより架材支持部６は常時架材に当接し、架材側の荷重を支持する。
【００２２】
なお、係止爪部８Ａの水平部８Ａａと係止段部９Ａの水平部９Ａａとが離間している間は、架材側の荷重の支持は、前記架材支持部６の係止爪部８Ａの水平部８Ａａと係止段部９Ａの水平部９Ａａとが接触するまで架材支持部６が下降することにより行われるが、係止段部９Ａのピッチを多くすれば、架材支持部６の僅かな上昇で次の段の水平部に係合することができ、また例えかつ前記水平部８Ａａと水平部９Ａａが離間しているときでも、架材支持部６の僅かな下降で架材側の荷重を主軸４側に直接伝達することができる。
【００２３】
次に架材支持部固定手段の構成について説明する。
図２及び図３において、符号１０は架材支持部６側に形成された係止爪部であり、前記係止爪部８Ａ乃至８Ｄと同様可撓性を有する材料により構成されている。一方主軸４側には、軸心に沿うようにガイド溝１１が形成され、かつ当該ガイド溝１１の下端部は溝本体にほぼ直交する係止溝１１Ａが連接されている。
【００２４】
前記ガイド溝１１は図３（Ａ）に示されるように、係止段部９Ａ及び９Ｂの中央部ではなく何れか一方に変位した位置（図示の構成では係止段部９Ｂ側に変位した位置）に形成されている。これにより図３（Ｂ）の如く係止爪部１０はガイド溝１１に嵌入しかつこの状態で架材支持部６を下降させると、係止爪部８Ａ乃至８Ｄのそれぞれは、点線ＤＬで示される係止爪部８Ａの移動軌跡に沿って移動することになり、架材支持部６の下降が可能となる。つまり各係止爪部８Ａ乃至８Ｄは各係止段部９Ａ乃至９Ｄと係合せず、従ってこの係止段部９Ａ乃至９Ｄに下降を阻止されることなく下降が可能となる。
【００２５】
次に、係止爪部１０がガイド溝１１の下端に至ったならば図３（Ｂ）に示すように架材支持部６をＡ方向に回動させ、前記係止爪部１０をカイド溝１１の本体部に連接する係止溝１１Ａに係止させる。これにより架材支持部６は内蔵されるコイルばね７の弾発力に抗して下端の位置で主軸４側に固定される。またこの状態で各係止爪部８Ａ乃至８Ｄは対応する係止段部９Ａ乃至９Ｄと係合する。
【００２６】
なお、図５に示すように架材支持部６の背面にも同様の係止爪部１３が形成さているが、この係止爪部１３は主軸４の背面の上端部近傍に凹設された係止溝１４と係合することにより、架材支持部６が最上部まで上昇した際に、当該係止爪１３が係止溝１４に係合することにより架材支持部６が主軸４から脱落するのを防止するストッパとしての機能を有している。
【００２７】
次に床束１の取り付け状態について説明する。
床束１は上述のように架材支持部６が主軸４側に固定された状態で床下に配置され、基台部２を土間に接地させることにより所定の位置に立設させる。この状態でナット５により架材支持部６が架材に当接するまで主軸４及び当該架材支持部６を上昇させる。架材支持部６が所定の位置で架材に当接したならば前記係止爪部１０を外側に折り曲げ、或いはこの係止爪部１０を架材支持部６から取り去ることにより主軸４に対する架材支持部６の固定状態を解除する。以後は前述のように、架材と地盤との距離の離間に対応して架材支持部６は架材に当接した状態で主軸４に沿って上昇し、かつ前記係止爪部８Ａ乃至８Ｄと係止段部９Ａ乃至９Ｄの係合により架材支持部６の下降は阻止され、架材の荷重は弾性体であるコイルばね７を介することなく主軸４側に直接伝達れ、架材を常時強固に支持する。
【００２８】
次に図１（Ｂ）の構成は本発明の変形例を示す。この構成は床束を上下対称に構成し、現場において符号６及び６´で示される部材のうち何れか一方を架材支持部として、他方を基台部として使用するよう構成したものである。なお基台部として利用する側の部材は、主軸４に対する固定状態を解除せずそのままの状態で使用する。なお、符号３Ａ、３Ｂは支持筒、４Ａ、４Ｂは主軸である。
【００２９】
次に同図（Ｂ）の符号１５で示すセンサについて説明する。このセンサは架材支持部６の上昇距離が一定値以上となったときにこの状態を外部に告知するためのセンサである。なお、このセンサ１５は同図（Ａ）に対してももとより実施可能である。
【００３０】
１５ａはセンサ本体であって、主軸４側に固定されている。１５ｂは架材支持部６側に固定されたピン部材であって、センサ本体内１５ａに挿入配置されており、架材支持部６の上昇に対応して当該センサ本体内１５ａ内を上昇するよう構成されている。センサ本体１５ａに所定の位置にスイッチ機構が設けられており、ピン部材１５ｂの下端がこのスイッチ機構の位置まで上昇した時に、外部に信号を発する構成となっている。
上記構成のセンサは床束の外部に設置した構成となっているが、要するに架材支持部６の上昇の度合いが検知できればよいので、上記構成以外に、センサを床束内部に内装し、このセンサにより主軸４と架材支持部６との離間を検知する等の構成も可能である。
【００３１】
本発明に係る床束は上記説明及び図に示す構成からも明らかなとおり、地盤と架材との距離の変位量に係わりなく対応できる構造となっているが、そもそもその変位量が極端に大きくなった場合には、構造物の変形、大規模な地盤沈下等、床束という支持構造のみで解決できない事態が生じている可能がある。従って、予め設定された変位量を越えた場合には前記センサ１５により警報を発する等して、床下の状態の確認を促すように構成することは非常に有効である。
【００３２】
なお、前記センシングシステムは例えば出願人等が先に提案している「木造構造物の接地環境監視改善システム」（特願２０００−２９３３２６号）におけるセンシングシステムの中に組み込むことも可能である。
【００３３】
【発明の効果】
本発明は以上に説明したように、弾性体の弾発力により、ボルトやナットを人手により調整することなく架材支持部を常時架材に当接することができ、かつ係合手段により架材支持部の下降は阻止されるので、架材側の荷重は架材支持部を介して直接主軸等の床束本体側に伝達され、この結果長期間に渡って所謂メンテナンスフリーで架材を強固に支持する事が可能となり、人手と経費を大幅に低減することが可能となる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor bundle that is vertically disposed via a slab or the like to support a building such as a house, and supports a base material such as a slab of the building.
[0002]
For example, in a wooden house, the floor portion of the house is supported by placing a support member made of wood or a metal material called a floor bundle between the floor and a floor supporting the floor portion of the house. It has a structure.
[0003]
[Prior art]
In the structure in which the floor is supported by the floor bundle, the floor bundle whose floor is fixed by the temporal change of wood such as warp or strain of the pulling or joist, or the floor is fixed to the floor, A gap often occurs between the slabs supporting the bundle and the floor bundle no longer fulfills its intended role. Further, in the case of a floor bundle not fixed as described above, the floor bundle itself may fall down.
[0004]
[Problems to be solved by the invention]
In view of such a point, there has also been provided a floor bundle in which a part of the floor bundle is formed into a screwed structure and, for example, the whole support height is adjustable by rotating a nut. However, in practice, adjusting the length of the floor bundle requires labor, such as workers having to go under the floor, individually adjusting the height of a large number of floor bundles, and having to regularly look under the floor. Is not a very effective solution.
[0005]
In view of such a point, the inventors house an elastic body such as a coil spring in a floor bundle, make the floor bundle expandable and contractable by using the elasticity of the elastic body, and always use the floor bundle as a frame member. A floor bundle that is pressed against the side is being developed separately.
[0006]
This floor bundle has a very simple structure and can automatically contact the floor bundle for a long period of time to support the frame even if the space between the frame and the soil changes. It is possible. On the other hand, the distance between the soil and the frame is all dependent on the elasticity of the elastic body, so if the elasticity of the elastic body is too strong, the force to push up the floor will work, and if it is too weak, the floor will work. However, in this configuration, it is necessary to carefully select an elastic body having a predetermined elastic force in accordance with the load on the floor to be supported.
[0007]
Japanese Patent Application Laid-Open No. 2001-59330 discloses a configuration of a floor bundle in which a coil spring is housed, which obliquely urges a locking piece that locks to a screw rod, The height adjustment of the floor bundle itself, not the elastic body for supporting the load, is also based on the screwing structure of the bolt and nut. That is, the present invention is based on the premise that the height of the floor bundle is periodically adjusted manually and aims to facilitate this height adjustment work.
[0008]
[Means for Solving the Problems]
The present invention is configured to solve the above-described technical problem, and the height of the floor bundle can be automatically adjusted, and the support of the frame member after the automatic height adjustment is performed by the elastic force of the elastic body. It is an object of the present invention to provide a floor bundle configured to be able to be fixedly supported by engagement of each member constituting the frame member without being engaged.
[0009]
That is, the present invention has a main shaft, and a bridge support portion that is supported by the main shaft and directly supports the bridge member by abutting against a bridge member of a building. An elastic body such as a coil spring is interposed and disposed in the frame, so that the frame support portion is configured to always contact the frame. An engaging means for engaging the frame supporting portion with the main shaft is provided on the frame supporting portion and the main shaft, and the engaging means allows the frame supporting portion to rise to the frame side, and It is configured to prevent descending to the side. Thus, the floor bundle is configured such that the load on the frame member side is directly transmitted from the frame member support portion to the main shaft side without passing through the elastic body.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
The support member is fixed to the main shaft by a locking means for fixing the support member against a resilient force of an elastic body (hereinafter, a "coil spring" will be described also by way of example) including the embodiment. Is fixed to the spindle in advance in a state closest to the top, that is, a state of descending toward the spindle.
[0011]
In this state, the floor bundle is arranged at a predetermined position below the floor of a structure such as a house. The main shaft is screwed with the support cylinder side, and the floor bundle arranged at a predetermined position raises and lowers the main shaft with respect to the axial direction of the support cylinder by adjusting a nut, and a frame support portion at the upper end of the main shaft. Adjust the height so that the abutment comes into contact with the frame.
[0012]
In this state, when the locking state of the locking means for fixing the support member is released, the support member comes into contact with the support member by the elastic force of the coil spring. As described in detail in the embodiment, since the coil spring does not function as a member for supporting the load on the frame, the elastic force of the coil spring is against the locking means for preventing the frame from lowering. As long as it has enough resilience to raise
[0013]
Since the frame supporting portion is directly engaged with the main shaft by the descent prevention locking means of the frame supporting portion, the load on the frame side is directly transmitted from the frame supporting portion to the main shaft. In this state, when the distance between the ground and the frame material is extended due to the subsidence of the ground or the like, the descent prevention locking means is configured to allow the frame material support portion to rise to the frame material side. Due to the resilience of the coil spring, the bridge supporting portion rises to the bridge side by that amount, maintains the state of contact with the bridge, and supports the load of the bridge.
[0014]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1A shows a basic configuration of the present invention, and FIG. 1B shows an application example. In the application example, the floor bundle is configured to be vertically symmetrical, and (A) illustrates a configuration in which the side that is in contact with the ground (ground) L and the support member are separately formed. Hereinafter, the configuration (A) will be mainly described as an example.
[0015]
In FIG. 1A, an arrow 1 indicates a floor bundle. Reference numeral 2 denotes a base portion for erecting the entire floor bundle on the ground L, and reference numeral 3 denotes a support tube fitted and fixed to the base portion 2. Reference numeral 4 denotes a main shaft, which is supported by the support tube 3 by screwing with a nut 5 arranged at the upper end of the support tube 3, and is rotated in the axial direction of the support tube 3 by adjusting the rotation of the nut 5. It is configured to be able to move up and down. Reference numeral 5a is a lock nut for locking the nut 5.
[0016]
Reference numeral 6 denotes a frame supporting portion attached to the main shaft 4. The structure of the connection between the support member 6 and the main shaft 4 will be described mainly with reference to FIG.
The frame support 6 is attached to the main shaft 4 such that the upper end side of the main shaft 4 is inserted into the frame support 6, and is supported by the main shaft 4.
[0017]
Reference numeral 7 denotes a coil spring, a part of which is housed in the internal space of the main shaft 4, and the other end of the coil spring comes into contact with the frame supporting portion 6 fitted into the main shaft 4, and It is configured to contact the material side. However, as described above, the coil spring 7 itself does not need to have a function of supporting the load on the frame material side, but merely abuts the frame material support portion 6 on the frame material side. The degree is sufficient, and therefore, a situation in which the frame is pushed upward by the frame support portion does not occur.
[0018]
A fixing means (hereinafter referred to as a "frame support portion fixing means") for fixing the frame support portion 6 to the main shaft 4 when the entire floor bundle 1 is attached between the frame support portion 6 and the main shaft 4. And a locking means (hereinafter referred to as a “frame supporting portion holding device”) that abuts the frame supporting portion 6 on the frame side and prevents the frame supporting portion 4 from descending when supporting the frame by the floor bundle. ") Is formed.
[0019]
First, the support member holding means will be described. In FIG. 2, reference numerals 8A and 8B denote locking claws, which are structures on the side of the support member 6 forming a part of the support member for holding the support member. In the configuration shown in the figure, the locking claw portions are formed at a total of four locations in the circumferential direction of the side wall of the support member 6 as shown by reference numerals 8C and 8D in FIG.
[0020]
On the other hand, locking step portions 9A to 9D corresponding to the locking claw portions 8A to 8D are formed on the main shaft 4 side (see FIGS. 2 and 5). As shown in FIGS. 4A and 4B, the locking steps 9A to 9D are formed by a continuation of a horizontal portion 9Aa and a sloping portion 9Ab that extends upward from the horizontal portion 9Aa in an overhang shape. It is configured as
[0021]
On the other hand, the lower end of the locking claw 8A on the side of the support member 6 has a horizontal portion 8Aa that engages with the horizontal portion 9Aa of the locking step 9A and a sloping portion 9Ab of the locking step 9A. A moving skewing portion 8Ab is formed. Further, the entire frame supporting portion 6 or at least a portion where the locking claw portion 8 is formed is made of a material having some flexibility such as vinyl chloride. Thereby, when the floor bundle 1 and the frame are displaced in a direction in which they are separated from each other, the frame supporting portion 6 is raised in accordance with the amount of displacement and in accordance with the elastic force of the internal coil spring 7. In response to the rise, the locking claw 8A flexes outward as indicated by reference numeral 8A 'due to its flexibility, and the skewed portion 8Ab rises while sliding in contact with the skewed portion 9Ab of the locking step 9A. When the contact state between the row portions 8Ab and 9Ab is released, the horizontal portion 8Aa of the locking claw portion 8A is positioned by its own restoring force on the horizontal portion 9Aa of the upper locking step portion. And the main shaft 4 are directly engaged again, and the load on the frame member is transmitted to the main shaft 4 side. By repeating this operation in accordance with the increase in the separation distance, the frame supporting portion 6 always comes into contact with the frame and supports the load on the frame.
[0022]
While the horizontal portion 8Aa of the locking claw portion 8A and the horizontal portion 9Aa of the locking step portion 9A are separated from each other, the support of the load on the bridge member side is performed by the locking claw portion of the frame member supporting portion 6. This is performed by lowering the supporting member support portion 6 until the horizontal portion 8Aa of the locking step portion 8A and the horizontal portion 9Aa of the locking step portion 9A come into contact with each other. 6 can be engaged with the horizontal portion of the next step by a slight rise, and even when the horizontal portion 8Aa and the horizontal portion 9Aa are separated from each other, the frame supporting portion 6 is slightly lowered and the frame is supported. The load on the material side can be directly transmitted to the main shaft 4 side.

Next, the structure of the frame support fixing means will be described.
In FIGS. 2 and 3, reference numeral 10 denotes a locking claw formed on the support member 6 side, and is made of a material having the same flexibility as the locking claw 8A to 8D. On the other hand, on the main shaft 4 side, a guide groove 11 is formed along the axis, and a lower end portion of the guide groove 11 is connected to a locking groove 11A substantially perpendicular to the groove main body.
[0024]
As shown in FIG. 3A, the guide groove 11 is displaced to one of the locking steps 9A and 9B, not to the center (in the configuration shown, the position displaced to the locking step 9B side). ). As a result, as shown in FIG. 3 (B), when the locking claw 10 is fitted into the guide groove 11 and the support member 6 is lowered in this state, each of the locking claw 8A to 8D is indicated by a dotted line DL. Since the engaging claw portion 8A moves along the movement trajectory of the engaging claw portion 8A, the frame support portion 6 can be lowered. That is, the locking claw portions 8A to 8D do not engage with the locking step portions 9A to 9D, so that the locking step portions 9A to 9D can be lowered without being prevented from lowering.
[0025]
Next, when the locking claw 10 reaches the lower end of the guide groove 11, as shown in FIG. 3 (B), the frame supporting portion 6 is rotated in the direction A, and the locking claw 10 is 11 is locked in a locking groove 11A connected to the main body. As a result, the frame supporting portion 6 is fixed to the main shaft 4 at the lower end position against the elastic force of the built-in coil spring 7. Also, in this state, the locking claws 8A to 8D engage with the corresponding locking steps 9A to 9D.
[0026]
As shown in FIG. 5, a similar locking claw 13 is also formed on the back surface of the support member 6, but this locking claw 13 is recessed near the upper end of the back surface of the main shaft 4. By engaging with the locking groove 14, when the frame supporting portion 6 rises to the uppermost portion, the locking claw 13 engages with the locking groove 14, so that the frame supporting portion 6 is separated from the main shaft 4. It has a function as a stopper for preventing it from falling off.
[0027]
Next, the mounting state of the floor bundle 1 will be described.
As described above, the floor bundle 1 is placed under the floor with the frame support portion 6 fixed to the main shaft 4 side, and the base portion 2 is erected at a predetermined position by being grounded to the ground. In this state, the main shaft 4 and the frame support 6 are raised until the frame support 6 is brought into contact with the frame by the nut 5. When the support member 6 comes into contact with the support member at a predetermined position, the locking claw portion 10 is bent outward, or the locking claw portion 10 is removed from the support member 6 so that the support member 4 can be mounted on the main shaft 4. The fixed state of the material support 6 is released. Thereafter, as described above, the supporting member supporting portion 6 rises along the main shaft 4 in a state of contact with the supporting member corresponding to the distance between the supporting member and the ground, and the engaging claw portions 8A to 8A are provided. The lowering of the frame support 6 is prevented by the engagement of the locking step portions 8A and the locking steps 9A to 9D, and the load of the frame is directly transmitted to the main shaft 4 side without passing through the coil spring 7 which is an elastic body. Is always strongly supported.
[0028]
Next, the configuration of FIG. 1B shows a modification of the present invention. In this configuration, the floor bundle is configured to be vertically symmetrical, and one of the members indicated by reference numerals 6 and 6 'is used on the site as a supporting member for supporting members and the other is used as a base. The member used as the base portion is used as it is without releasing the fixed state to the main shaft 4. Reference numerals 3A and 3B are support cylinders, and 4A and 4B are main shafts.
[0029]
Next, the sensor indicated by reference numeral 15 in FIG. This sensor is a sensor for notifying this state to the outside when the ascending distance of the frame supporting portion 6 becomes a predetermined value or more. Note that the sensor 15 can also be implemented with respect to FIG.
[0030]
A sensor body 15a is fixed to the main shaft 4 side. Reference numeral 15b denotes a pin member fixed to the frame supporting portion 6 side, which is inserted and arranged in the sensor main body 15a so as to rise in the sensor main body 15a in response to the rising of the frame supporting portion 6. It is configured. A switch mechanism is provided at a predetermined position in the sensor main body 15a, and a signal is issued to the outside when the lower end of the pin member 15b is raised to the position of the switch mechanism.
Although the sensor having the above configuration is configured to be installed outside the floor bundle, it is only necessary to be able to detect the degree of elevation of the frame material supporting portion 6. In addition to the above configuration, the sensor is provided inside the floor bundle, A configuration in which the sensor detects the separation between the main shaft 4 and the frame supporting portion 6 or the like is also possible.
[0031]
As is clear from the above description and the configuration shown in the drawings, the floor bundle according to the present invention has a structure that can respond regardless of the displacement amount of the distance between the ground and the frame material, but the displacement amount is extremely large in the first place. In such a case, there is a possibility that a situation such as deformation of a structure or large-scale land subsidence that cannot be solved only by a support structure called a floor bundle may occur. Therefore, when the displacement exceeds a preset amount, it is very effective to provide a warning by the sensor 15 or the like to prompt confirmation of the under-floor state.
[0032]
The sensing system can be incorporated in a sensing system in, for example, a "wooden structure grounding environment monitoring improvement system" (Japanese Patent Application No. 2000-293326) previously proposed by the applicant or the like.
[0033]
【The invention's effect】
As described above, according to the present invention, the elastic support of the elastic member allows the support member to be always in contact with the support member without manually adjusting bolts and nuts, and the support member is provided with the engaging means. Since the lowering of the support portion is prevented, the load on the frame member is transmitted directly to the floor bundle body such as the main shaft through the frame member support portion, and as a result, the member is rigidly maintained for a long time without maintenance. And labor and costs can be greatly reduced.
