Description

本発明は仮設構造物の床板固定用具に係り、特に構台の床板の固定に適した固定用具に関するものである。   The present invention relates to a floor plate fixing tool for a temporary structure, and more particularly to a fixing tool suitable for fixing a floor plate of a gantry.

仮設構造物の一つである構台は、仮設の支柱、床等によりある程度の高さに構成された設備であり、仮設道路や、部材の集積や建設機械等の作業台や足場台として利用されている。
特許文献１に示すものは一例であり、左右及び前後方向に所定の間隔を開けて多数の支柱が並列した配置で立設されており、その隣り合う支柱間を横架材が繋いでいる。横架材は上下方向に間隔を開けて複数配置されており、隣り合う支柱と横架材とで四角形の枠組みが形成され、更に、この四角形の枠組みの対角部間に筋交いが掛け渡される。このような組み合わせで、骨組構造体が構築されている。 The gantry, which is one of the temporary structures, is a facility constructed to a certain height with temporary columns, floors, etc., and is used as a work platform and scaffolding for temporary roads, material accumulation and construction machinery, etc. ing.
The one shown in Patent Document 1 is an example, and a large number of support columns are arranged in parallel at predetermined intervals in the left-right and front-rear directions, and a horizontal member is connected between the adjacent support columns. A plurality of horizontal members are arranged at intervals in the vertical direction, and a quadrangular frame is formed by the adjacent struts and the horizontal members, and further, braces are spanned between diagonal portions of the quadrangle frame. .

特開２０１１−３８３５２号公報JP 2011-38352 A 特開２０１６−２３４１０号公報JP 2006-23410 A

支柱の上部側では、大引材が掛け渡され、その上に根太材が架設されて、大引材と根太材とが格子状に配置されており、根太材上に床板材が敷設されて、最上面となる部分に床板が構築されている。この床板材は、二層構造で下側が木板で上側が鉄板で構成されており、最上面を鉄板で構成することで、キャタピラ車や大型ダンプのような重量車両が走行しても床板が強度的に耐え得るようになっている。   On the upper side of the column, a large pulling material is stretched, a joist is laid on it, and the large pulling and joist are arranged in a grid, and the floor board is laid on the joist The floorboard is constructed on the top surface. This floor board material is a two-layer structure with the lower side made of wood and the upper side made of iron, and the top is made of steel, so that the floor is strong even when heavy vehicles such as caterpillar cars and large dump trucks run. To withstand.

而して、足場台や２トン、３トントラックのような車両が走行する仮設道路までは、強度的には木板で十分に対応できることから、最近では、鉄板を敷設せずに済ませようとする傾向がある。
しかしながら、床板材は切板を並べただけになっているので、軽量な木製の切板だけで最上面を構成するとなると、車両が走行したり、下方からの風にあおられたりしたときに、捲れあがってズレてしまう恐れがある。
そのため、通常は、切板に孔をあけておき、そこに番線を通して支柱や横架材と結束固定しているが、番線は比較的容易に伸びてしまい、番線が飛び出すと引っ掛かり易くなって走行の邪魔になるので、番線の交換作業が頻繁に必要となっている。 Thus, up to temporary roads where vehicles such as scaffolding platforms and 2 ton and 3 ton trucks run can be adequately handled with wooden boards, and recently, there is a tendency to avoid laying iron plates. There is.
However, since the floorboard material consists only of cut plates, when the top surface is composed only of lightweight wooden cut plates, when the vehicle runs or is hit by the wind from below, There is a risk of getting out of touch.
For this reason, usually, a hole is made in the cut plate, and it is bound and fixed to a post or horizontal member through a number wire, but the number wire is relatively easy to stretch, and when the number wire jumps out, it becomes easy to catch. Therefore, it is necessary to replace the wire frequently.

ところで、車両走行用の床板材として鉄製の切板を敷設する場合であっても、安全率を高めるために固定する場合があり、そのような場合従来は溶接によって固定していたが、本発明者は、先に、特許文献２で、溶接によらずに固定することを可能にするために、特殊な固定用具の利用を提案しているが、この固定用具は鉄板側にネジ孔を設けることが前提となっており、木製の切板に応用することはできない。   By the way, even in the case of laying an iron cut board as a floor board material for vehicle travel, it may be fixed in order to increase the safety factor. In such a case, it is conventionally fixed by welding. The person has previously proposed the use of a special fixing tool in Patent Document 2 to enable fixing without welding, but this fixing tool is provided with a screw hole on the iron plate side. Therefore, it cannot be applied to wooden cutting boards.

本発明は上記従来の問題点に着目して為されたものであり、上記した固定用具に更に工夫を凝らし、仮設構造物の床板を木製の切板で構成したときに、番線に代わってその床板を固定するのに適した固定用具を提供することを、その目的とする。   The present invention has been made paying attention to the above-mentioned conventional problems, and when the above-described fixing tool is further devised, when the floor plate of the temporary structure is configured with a wooden cut plate, the wire is replaced with a wire. It is an object of the present invention to provide a fixing tool suitable for fixing a floor board.

本発明の実施の形態に係る床板固定具１の構成を、図１にしたがって説明する。
この床板固定具１は、鋼製になっている。
符号３は中継体を示す。この中継体３は細長い長円状の環を成しており、中間部は平行になっている。この中間部の幅はそれ程大きくはなく、片手で十分に把持できるようになっている。また、長軸方向両端部は幾分か肉厚になっており、そこにはそれぞれネジ孔が形成されて雌ネジ部５、７になっている。この雌ネジ部５、７は同軸状に位置決めされて上下に対向している。更に、雌ネジ部５と雌ネジ部７は互いに逆ネジの関係を作っている。 The structure of the floor board fixture 1 which concerns on embodiment of this invention is demonstrated according to FIG.
This floor board fixture 1 is made of steel.
Reference numeral 3 denotes a relay body. The relay body 3 forms an elongated oval ring, and the intermediate portion is parallel. The width of the intermediate portion is not so large and can be sufficiently grasped with one hand. Further, both end portions in the long axis direction are somewhat thickened, and screw holes are formed in the respective end portions to form female screw portions 5 and 7. The female screw portions 5 and 7 are positioned coaxially and face each other vertically. Furthermore, the female screw portion 5 and the female screw portion 7 have a reverse screw relationship with each other.

符号９、１５はシャフト部を示す。このシャフト部９、１５は中継体３を挟んで上下に配置されており、シャフト部９が上側に、シャフト部１５が下側に位置されている。
シャフト部９の軸方向下端側の外周面はネジが形成されて雄ネジ部１１になっており、上端側は曲げられてフック状の掛止部１３になっている。この雄ネジ部１１は上記した中継体３の雌ネジ部５に螺合するよう形成されている。従って、シャフト部９の雄ネジ部１１が中継体３の雌ネジ部５に上側から差し込まれ、螺合されると、螺進退が可能になる。
シャフト部１５もシャフト部９と同じように、但し上下逆に構成されており、シャフト部１５の軸方向上端側は雄ネジ部１７になっており、下端側はフック状の掛止部１９になっている。従って、シャフト部１５の雄ネジ部１７が中継体３の雌ネジ部７に下側から差し込まれ、螺合されると、螺進退が可能になる。 Reference numerals 9 and 15 denote shaft portions. The shaft portions 9 and 15 are arranged above and below the relay body 3, and the shaft portion 9 is located on the upper side and the shaft portion 15 is located on the lower side.
A screw is formed on the outer peripheral surface on the lower end side in the axial direction of the shaft portion 9 to form a male screw portion 11, and the upper end side is bent to form a hook-shaped hook portion 13. The male screw portion 11 is formed so as to be screwed into the female screw portion 5 of the relay body 3 described above. Accordingly, when the male screw portion 11 of the shaft portion 9 is inserted into the female screw portion 5 of the relay body 3 from the upper side and screwed, the screw can be advanced and retracted.
The shaft portion 15 is configured upside down in the same manner as the shaft portion 9, but the upper end side in the axial direction of the shaft portion 15 is a male screw portion 17, and the lower end side is a hook-shaped latching portion 19. It has become. Therefore, when the male screw portion 17 of the shaft portion 15 is inserted into the female screw portion 7 of the relay body 3 from the lower side and screwed, the screw can be advanced and retracted.

上記したように、中継体３には、上側からシャフト部９が連結され、下側からシャフト部１５が連結されて軸状になっている。中継体３の環内の上下寸法は、シャフト部９、１５の雄ネジ部１１、１７の長さ寸法に対して十分に長く設定されているので、両方が中継体３の環内に最大限入り込んだときでも、当たることはない。
上記した逆ネジの関係により、シャフト部９、１５に対して、中継体３をその長軸方向を軸方向として軸周りに回転させると、両方のシャフト部９、１５の中継体３の環内への進退が連動して起こり、シャフト部９の雄ネジ部１１が中継体３の環内に退行するときは、シャフト部１５の雄ネジ部１７も中継体３の環内に退行し、シャフト部９の雄ネジ部１１が中継体３の環外に進行するときは、シャフト部１５の雄ネジ部１７も中継体３の環外に進行する。 As described above, the shaft portion 9 is connected to the relay body 3 from the upper side, and the shaft portion 15 is connected from the lower side to have an axial shape. Since the vertical dimension in the ring of the relay body 3 is set sufficiently long with respect to the length dimension of the male screw parts 11 and 17 of the shaft portions 9 and 15, both are maximum in the ring of the relay body 3. Even if you get in, you won't win.
When the relay body 3 is rotated around the axis with the long axis direction as the axial direction with respect to the shaft portions 9 and 15 due to the reverse screw relationship described above, the inside of the relay body 3 of both the shaft portions 9 and 15 When the male threaded portion 11 of the shaft portion 9 retreats into the ring of the relay body 3, the male threaded portion 17 of the shaft portion 15 also retreats into the ring of the relay body 3, so that the shaft When the male screw portion 11 of the portion 9 advances outside the ring of the relay body 3, the male screw portion 17 of the shaft portion 15 also advances outside the ring of the relay body 3.

符号２１は取付け体を示し、この取付け体２１は二枚の薄板材で構成されている。上側の四角の板材は当接板２３になっている。この当接板２３は正方形に近い長方形になっており、長手寸法と短手寸法の差は大きくない。
当接板２３の下面に吊架板２５が溶接固定されている。この吊架板２５は全体として長方形状になっているが、一方の短手縁側は丸みが付けられて半円弧状の縁部２６になっている。この円弧状縁部２６側に丸い孔部２７が貫通形成されている。この孔部２７は上記したシャフト部９の掛止部１３が掛止し易いように大きさや位置が調整されている。 Reference numeral 21 denotes an attachment body, and the attachment body 21 is composed of two thin plate members. The upper square plate material is a contact plate 23. The contact plate 23 has a rectangular shape close to a square, and the difference between the long dimension and the short dimension is not large.
A suspension plate 25 is fixed to the lower surface of the contact plate 23 by welding. The suspension plate 25 has a rectangular shape as a whole, but one short edge side is rounded to form a semicircular edge 26. A round hole 27 is formed through the arcuate edge 26 side. The size and position of the hole portion 27 are adjusted so that the hook portion 13 of the shaft portion 9 can be easily hooked.

吊架板２５は、両板面が左右方向を向き、円弧状縁部２６が下方を向いた状態で、その上端の板厚部分が、当接板２３の長手方向中心線に重ねて固定されている。吊架板２５は当接板２３の縁部内に収められており、外方にははみ出していない。
吊架板２５と当接板２３は板面どうしが垂直に交差しており、吊架板２５を左右方向の板厚部分から見ると、取付け体２１はＴ字状をなしている。 The suspension plate 25 is fixed so that the plate thickness portion at the upper end overlaps the longitudinal center line of the contact plate 23 with both plate surfaces facing left and right and the arcuate edge 26 facing downward. ing. The suspension plate 25 is accommodated in the edge portion of the contact plate 23 and does not protrude outward.
The plate surfaces of the suspension plate 25 and the contact plate 23 intersect each other vertically, and when the suspension plate 25 is viewed from the plate thickness portion in the left-right direction, the attachment body 21 has a T shape.

床板固定具１は上記したように構成されており、図２に示すように並べられた切板２９を固定するのに利用される。
この切板２９は木製になっており、図３〜図５に示す構台３１の一部を構成している。いずれも、固定具１の使用状態が示されており、図３では上面図が、図４ではそのＡ−Ａ断面図が、図５では図４と直角方向の一部断面図が示されている。
この構台３１は、左右及び前後方向に所定の間隔を開けて多数の支柱３３、３３、……が並列した配置で立設されている。その隣り合う支柱３３、３３どうしを横架材としてのパイプ３５がパイプ固定金具３７を介して繋いでいる。パイプ３５は上下方向に間隔を開けて複数配置されており、隣り合う支柱３３、３３とパイプ３５、３５とで四角形の枠組みが形成され、更に、この枠組みの対角部間には筋交い（図示省略）が架け渡されており、支柱３３、パイプ３５、筋交いの組み合わせで骨組構造体が構築されている。 The floor plate fixture 1 is configured as described above, and is used to fix the cut plates 29 arranged as shown in FIG.
The cut plate 29 is made of wood and constitutes a part of the gantry 31 shown in FIGS. In both cases, the use state of the fixture 1 is shown. In FIG. 3, a top view is shown, FIG. 4 is a sectional view taken along line AA, and FIG. 5 is a partial sectional view perpendicular to FIG. Yes.
This gantry 31 is erected in such a manner that a large number of support pillars 33, 33,... The adjacent support columns 33 and 33 are connected to each other by a pipe 35 as a horizontal member through a pipe fixing bracket 37. A plurality of pipes 35 are arranged at intervals in the vertical direction, and a quadrangular frame is formed by the adjacent support columns 33 and 33 and the pipes 35 and 35, and further, struts are formed between diagonal portions of the frame (illustrated). The frame structure is constructed by a combination of the support 33, the pipe 35 and the braces.

この骨組構造体の支柱３３の上部側では、大引材固定金具３９を介して固定された状態で大引材４１が支柱３３間に掛け渡され、その上には根太材４３が架設されており、大引材４１と根太材４３とが上面視格子状に配置されている。そして、根太材４３上に、床板材としての切板２９が並べられている。図３に示すように、縦横に配置されており、切板２９の両方の短辺縁が根太材４３、４３に両持ち支持された状態になっている。隣り合った切板２９、２９どうしの間には小さな隙間４５があけられている。
床板固定具１は、この隣り合って並べられた切板２９、２９どうしを連結すると共に、パイプ３５に対して、以下の手順で固定するようになっている。 On the upper side of the support column 33 of the framework structure, the extended member 41 is stretched between the support columns 33 in a state of being fixed through the extended member fixing bracket 39, and a joist member 43 is erected thereon. In addition, the large pull material 41 and the joist material 43 are arranged in a lattice shape in a top view. And the cut board 29 as a floor board material is arranged on the joist 43. As shown in FIG. 3, they are arranged vertically and horizontally, and both short edges of the cut plate 29 are both supported by the joists 43 and 43. A small gap 45 is formed between the adjacent cut plates 29 and 29.
The floor board fixture 1 connects the cut plates 29 and 29 arranged side by side and fixes the pipes 35 to the pipe 35 in the following procedure.

シャフト部９〜中継体３〜シャフト部１５は螺合により軸状に一体化して、両端が掛止部１３、１９になった状態にしておく。この状態になったものを、説明の便宜のために、連結シャフト４７とする。
そして、切板２９、２９どうしの間の隙間４５に取付け体２１の吊架板２５を円弧状縁部２６側から差し込む。吊架板２５は隙間４５に入り込んでいき、当接板２３の下面が切板２９の上面に当接する。このとき、当接板２３は、隙間４５を挟んで両側の切板２９、２９の上面に跨った状態となっている。また、吊架板２５の円弧状縁部２６側は、隙間４５から抜け出て切板２９、２９の下面より突出する。 The shaft portion 9 to the relay body 3 to the shaft portion 15 are integrated into a shaft shape by screwing so that both ends become the hook portions 13 and 19. In this state, the connecting shaft 47 is used for convenience of explanation.
Then, the suspension plate 25 of the attachment body 21 is inserted into the gap 45 between the cut plates 29 and 29 from the arcuate edge 26 side. The suspension plate 25 enters the gap 45, and the lower surface of the contact plate 23 contacts the upper surface of the cut plate 29. At this time, the contact plate 23 is in a state of straddling the upper surfaces of the cut plates 29 and 29 on both sides with the gap 45 interposed therebetween. Further, the arcuate edge portion 26 side of the suspension board 25 protrudes from the lower surfaces of the cut plates 29 and 29 through the gap 45.

この下方に突出した吊架板２５の孔部２７に、シャフト部９の掛止部１３を差し込んで掛止させると共に、支柱３３側に横架されているパイプ３５を、シャフト部１５の掛止部１９に下側から抱き込ませる。
連結シャフト４７は中継部３を回転することで長さを調整できるので、上記した掛止部１３、１９の掛止めは容易にできる。
その後、連結シャフト４７を縮めて緊張させると、図４、図５に示すように、切板２９、２９が根太材４３側に押し付けられて固定される。
連結シャフト４７を伸ばせば緊張は解除されるので、床板固定具１は容易に取り外すことができ、構台３１を分解する際にも作業負担が少ない。 The hook portion 13 of the shaft portion 9 is inserted into the hole portion 27 of the suspension plate 25 protruding downward to be hooked, and the pipe 35 horizontally mounted on the column 33 side is hooked to the shaft portion 15. The part 19 is embraced from below.
Since the length of the connecting shaft 47 can be adjusted by rotating the relay portion 3, the above-described latching portions 13 and 19 can be easily latched.
Thereafter, when the connecting shaft 47 is contracted and tensioned, the cut plates 29 and 29 are pressed and fixed to the joist 43 side as shown in FIGS.
Since the tension is released when the connecting shaft 47 is extended, the floor board fixture 1 can be easily removed, and the work load is reduced when the gantry 31 is disassembled.

なお、床板固定具１は、図３に示すように、二枚の切板２９、２９に跨るように取付けるだけでなく、四枚の切板２９、２９、２９、２９に跨るように取付けることもできる。
この床板固定具１を使用して固定すれば、隙間４５を上手く利用して複数の切板２９を同時に効率良く固定することができる。 In addition, as shown in FIG. 3, the floor board fixture 1 is attached not only so as to straddle the two cut plates 29, 29 but also to straddle the four cut plates 29, 29, 29, 29. You can also.
If it fixes using this floor-plate fixing tool 1, the several cut board 29 can be efficiently fixed simultaneously using the clearance gap 45 well.

また、取付け体２１に代えて、図５の拡大斜視図に示すように、当接板２３のサイズを半分にした当接板４９を使用し、吊架板２５をその縁部に逆Ｌ字状に固定した取付け体５１を利用することもできる。
この取付け体５１を、床板の縁部側に配置された切板２９に対して取付ければ、金具が外方に突出せずに済む。二枚の切板２９、２９を連結する場合だけでなく、一枚の切板２９に単独で取付けることも可能である。
取付け体５１を併用することで、床板の縁部側に配置された切板２９を含めて、全ての切板２９を複数の箇所で固定して捲れあがりを確実に阻止することが可能となっている。 Further, in place of the attachment body 21, as shown in the enlarged perspective view of FIG. 5, a contact plate 49 in which the size of the contact plate 23 is halved is used, and the suspension plate 25 is inverted L-shaped at the edge thereof. A mounting body 51 fixed in a shape can also be used.
If the attachment body 51 is attached to the cut plate 29 arranged on the edge side of the floor board, the metal fitting does not protrude outward. In addition to the case where the two cut plates 29 and 29 are connected, it is possible to attach the cut plate 29 alone to the single cut plate 29.
By using the attachment body 51 in combination, it becomes possible to reliably prevent the rising up by fixing all the cutting plates 29 including the cutting plate 29 arranged on the edge side of the floor board at a plurality of locations. ing.

以上、本発明の実施の形態について詳述してきたが、具体的構成は、この実施の形態に限られるものではなく、本発明の要旨を逸脱しない範囲における設計の変更などがあっても発明に含まれる。
例えば、上記の実施の形態では大引材は固定金具により支柱側に固定されているが、支柱に大引受を取付け、そこに単純に載せただけの場合もあり、そのような場合には、大引材も併せて固定されることになる。 The embodiment of the present invention has been described in detail above. However, the specific configuration is not limited to this embodiment, and the present invention can be changed even if there is a design change without departing from the gist of the present invention. included.
For example, in the above embodiment, the large pulling material is fixed to the column side by the fixing bracket, but there is a case where the large pulling is attached to the column and simply placed on the column, in such a case, The large draw material is also fixed together.

また、床板固定具１は、以下のような使い方もある。
図６のように、取付け体２１の孔部２７にシャフト部９の掛止部１３を掛止させた後塑性加工によりフックの開放部分を閉じて環状体５３にしておき、他方のシャフト部１５は中継体３と螺合させておく。すなわち、床板固定具１を、（取付け体２１〜シャフト部９）と、（中継体３〜シャフト部１５）に分離しておく。
その上で、取付け体２１を切板２９に対して取付けていき、シャフト部１５をパイプ３５に掛止した後に、シャフト部９と中継体３とを連結（螺合）するようにする。
シャフト部９と中継体３の連結（螺合）の方が、取付け体２１とシャフト部９の連結（掛止）よりも、作業し易い。また、シャフト部９の掛止部１３は閉じた環状体５３になっているので、上記の作業中にシャフト部９が取付け体２１から外れることはない。 Moreover, the floor board fixture 1 can also be used as follows.
As shown in FIG. 6, after the hook portion 13 of the shaft portion 9 is hooked in the hole portion 27 of the attachment body 21, the hook open portion is closed by the plastic working to form the annular body 53, and the other shaft portion 15. Is screwed to the relay body 3. That is, the floor board fixture 1 is separated into (attachment 21 to shaft 9) and (relay 3 to shaft 15).
Then, the attachment body 21 is attached to the cutting plate 29, and after the shaft portion 15 is hooked on the pipe 35, the shaft portion 9 and the relay body 3 are connected (screwed together).
The connection (screwing) between the shaft portion 9 and the relay body 3 is easier to work than the connection (hanging) between the attachment body 21 and the shaft portion 9. Moreover, since the latching | locking part 13 of the shaft part 9 is the closed annular body 53, the shaft part 9 does not remove | deviate from the attachment body 21 during said operation | work.

切板２９を全て敷設し終えた後に、床板固定具１を取付けるような場合、例えば、床板固定具１を交換するような場合には、中継体３の挿通できるような隙間４５は無いので、図１に示すように、（取付け体２１）と、（シャフト部９〜中継体３〜シャフト部１５）に分離しておくことになる。
しかしながら、通常は、固定基準箇所から順番に切板２９を敷設していくので、すなわち片側端から順番に切板２９を敷設していくので、切板２９を敷設する合間に取付け体２１をシャフト部９を繋げた状態で取付けていくことができ、中継体３を取付け体２１側に連結させた状態で取付け体２１の設置作業を進めることができる。 When the floor plate fixture 1 is installed after all the cut plates 29 have been laid, for example, when the floor plate fixture 1 is replaced, there is no gap 45 through which the relay body 3 can be inserted. As shown in FIG. 1, (attachment body 21) and (shaft portion 9 to relay body 3 to shaft portion 15) are separated.
However, since the cut plate 29 is normally laid in order from the fixed reference point, that is, the cut plate 29 is laid in order from one side end, the attachment body 21 is attached to the shaft between the cut plate 29 lays. It can attach in the state which connected the part 9, and the installation operation | work of the attachment body 21 can be advanced in the state which connected the relay body 3 to the attachment body 21 side.
