Description

本発明は、橋梁,トンネル,桟橋など構造物の路面を構成するパネル状構造物としての溝形部材を用いた床版または覆工板用の版状パネルおよびその製造方法に関する。   The present invention relates to a plate-like panel for a floor slab or lining plate using a groove-shaped member as a panel-like structure constituting a road surface of a structure such as a bridge, tunnel, pier and the like, and a method for manufacturing the same.

従来、(1)床版橋としては、例えば、支間15m以下程度の小規模な橋梁では、主として経済性の面から、プレキャストコンクリート桁を用いた床版橋や、底鋼板にずれ止めを溶接した鋼殻とコンクリートとを合成してなる合成床版橋が用いられている。また、溝形部材を集成してなる床版橋なども知られている(例えば、特許文献1,2参照)。   Conventionally, (1) For floor slab bridges, for example, small bridges with a span of about 15m or less, mainly from the economical viewpoint, welded to the floor slab bridge using precast concrete girders and bottom steel plate Synthetic floor slab bridges made of steel shell and concrete are used. In addition, a floor slab bridge formed by collecting groove-shaped members is also known (for example, see Patent Documents 1 and 2).

また、(2)床版としては、例えば、橋梁一般に用いられる、桁の上に設置される床版では、主として経済性の面から鉄筋コンクリート床版が、耐久性の面からプレストレストコンクリート床版や底鋼板にずれ止めを溶接した鋼殻とコンクリートとを合成してなる合成床版などが用いられている。   (2) As floor slabs, for example, floor slabs installed on girders, which are generally used for bridges, are mainly reinforced concrete slabs from the viewpoint of economy, prestressed concrete slabs and bottoms from the viewpoint of durability. Synthetic floor slabs, etc., made by synthesizing steel shells and concrete with welded stoppers on steel plates, are used.

また、(3)覆工板としては、地下鉄工事、地下街建設工事、または桟橋工事などに用いられる一般的な覆工板は、H形鋼のフランジ同士を溶接した構造である(例えば、特許文献3参照)。近年、施工の効率化、経済化などを目的として、覆工板を大型化して、路面開削の際に覆工板を支持するために必要となる受桁、および柱の数を減らすことが考えられている。しかし、大型の覆工板構造を考えた場合、作業空間を確保することを目的として覆工板の桁高さを抑えるために、従来よりも剛性の高い溝形部材を用いる必要があり、また、覆工板は転用され、繰り返し何度も利用されることがあるため、長期間の使用に耐えられる耐久性が求められ、疲労強度等、耐久性に優れた構造とすることが求められている。

(3) As a lining board, a general lining board used for subway construction, underground shopping, pier construction, or the like has a structure in which flanges of H-shaped steel are welded to each other (for example, Patent Literature 3). In recent years, for the purpose of improving construction efficiency and economy, it is considered to increase the size of the lining plate and reduce the number of beams and columns required to support the lining plate during road excavation. It has been. However, when considering a large lining plate structure, it is necessary to use a channel member with higher rigidity than before in order to suppress the girder height of the lining plate for the purpose of securing a working space. Because the lining board is diverted and may be used over and over again, durability that can withstand long-term use is required, and a structure with excellent durability such as fatigue strength is required. Yes.
Japanese Utility Model Publication No. 56-005710 (Structural floor slab) JP-A-2004-285323 (floor bridge and floor slab unit) JP-A-9-296407 (lining plate)

前記(1)の従来技術の場合、下記(a)〜(c)のような課題がある。   In the case of the prior art (1), there are the following problems (a) to (c).

(a)コンクリート床版橋では自重が重いため、架設時に大型の重機が必要になることや、鋼橋に比べて下部工が比較的大きくなり、トータルコストが増加するという問題があり、また、1ブロックあたりの重量が大きいために輸送できるプレキャスト床版ブロックの大きさが限られ、輸送効率が悪いという問題がある。
また、(b)合成床版橋では、鋼殻の製作過程で溶接が必要となるため、加工コスト、疲労強度の面で問題がある。
(A) The concrete floor slab bridge has its own weight, so there is a problem that a large heavy machine is required at the time of erection, the substructure becomes relatively larger than the steel bridge, and the total cost increases. Since the weight per block is large, there is a problem that the size of the precast floor slab block that can be transported is limited and the transport efficiency is poor.
Further, (b) the composite floor slab bridge has problems in terms of processing cost and fatigue strength because welding is required in the process of manufacturing the steel shell.

また、(c)形鋼を集成してなる床版橋では、特許文献1の角形鋼管のように閉断面の部材を用いると平米あたりの鋼重が重くなり、経済化が阻害される恐れがある。また、特許文献2のように安価なH形鋼を用いようとすると、形鋼のフランジ同士を当接させるためにフランジ端部の厚さを大きくする必要があり、形鋼の製造に特別な装置が必要になる。   In addition, in (c) floor slab bridges made of shaped steel, if a member with a closed cross section is used like the square steel pipe of Patent Document 1, the steel weight per square meter may be heavy, which may hinder the economy. is there. In addition, if an inexpensive H-section steel is used as in Patent Document 2, it is necessary to increase the thickness of the flange end in order to bring the flanges of the section steel into contact with each other. Equipment is required.

前記(2)の従来の床版の場合、下記(d)〜(g)のような課題がある。   In the case of the conventional slab of (2), there are the following problems (d) to (g).

(d)鉄筋コンクリート床版では、桁の上に型枠を組み、鉄筋を組み立ててからコンクリートを打設し、コンクリートが硬化するまでを現場で一貫して施工する必要があるため、工期が長くかかるといった問題がある。
(e)プレストレストコンクリート床版では、鉄筋コンクリート床版の場合と同様、桁の上に型枠を組み、鉄筋を組み立ててからコンクリートを打設し、コンクリートが硬化した後にさらにセンターホールジャッキなどの軸力導入器具を用いてPC鋼材を緊張して床版にプレストレスを導入する工程が加わるため、工期が長くなるとともに作業が煩雑になる問題がある。
(f)合成床版は、鋼殻の製作過程で溶接が必要となるため、加工コスト、疲労強度の面で問題がある。
(g)さらに、現場での工期を短縮するため、コンクリートを工場にてあらかじめ打設するプレキャスト床版も開発されているが、床版橋の場合と同様、1ブロックあたりの重量が大きいために輸送できるプレキャスト床版ブロックの大きさが限られ、輸送効率が悪いという問題がある。
(D) With reinforced concrete floor slabs, it is necessary to construct a formwork on the girders, assemble the rebar, cast concrete, and work consistently on site until the concrete hardens. There is a problem.
(E) In the case of prestressed concrete slabs, as in the case of reinforced concrete slabs, formwork is put on the girders, the reinforcing bars are assembled, and then the concrete is placed. Since a process of introducing prestress into the floor slab by tensioning the PC steel material using the introduction tool is added, there is a problem that the work period becomes long and the work becomes complicated.
(F) Synthetic floor slabs have problems in terms of processing cost and fatigue strength because welding is required in the manufacturing process of the steel shell.
(G) Furthermore, in order to shorten the construction period at the site, precast floor slabs in which concrete is cast in advance at the factory have also been developed, but as with the floor slab bridge, the weight per block is large. There is a problem that the size of the precast slab block that can be transported is limited and the transport efficiency is poor.

前記(3)の従来の覆工板の場合、下記(h)のような課題がある。   In the case of the conventional lining board (3), there is the following problem (h).

(h)例えば、図14に示すように、従来の覆工板34aは、H形鋼部材32の組み立てに、フランジ33相互の溶接Wを含む溶接を多用しており、加工度、ならびに耐久性の面で課題があった。その他に、複数の角形鋼管を平行に配列しその長手方向の両端に複数の角形鋼管に渡って鋼材を溶接して相互に一体化する覆工板があるが、これも製作過程で溶接が必要となるため、加工コスト、疲労強度の面で問題があった。   (H) For example, as shown in FIG. 14, the conventional lining plate 34 a uses a lot of welding including welding W between the flanges 33 for assembling the H-shaped steel member 32. There was a problem in terms of. In addition, there is a lining plate that arranges a plurality of rectangular steel pipes in parallel and welds the steel materials across the square steel pipes at both ends in the longitudinal direction to integrate them together. Therefore, there were problems in terms of processing cost and fatigue strength.

本発明は、上記の課題を解決できると共に、特許文献2のように、フランジにリップなどの特殊な形状を設ける必要がなく、高価な熱延設備が必要なく、またフランジを切り欠き加工する場合でも既存の工場設備を利用して加工でき、安価に溝形部材を製作でき、また、市販の安価な溝形鋼を用いることでコスト低減を図ることも可能な溝形部材を用いた床版または覆工板用の版状パネルおよびその製造方法を提供することを目的する。
特に本発明は、平行に配列したフランジおよびウェブを有する複数の溝形部材を、溶接を用いないで接合一体化する溝形部材を用いた床版または覆工板用の版状パネルおよびその製造方法を提供することを目的とする。

However, floor slabs using channel members that can be processed using existing factory equipment, can be manufactured at low cost, and can be reduced in cost by using commercially available inexpensive channel steel. Another object of the present invention is to provide a plate-like panel for a lining plate and a method for producing the same.

次に、本発明を図示の実施形態に基づいて詳細に説明する。     Next, the present invention will be described in detail based on the illustrated embodiment.

図1は、第一の実施形態である溝形鋼を加工してなる溝形部材1を用いた床版橋4の斜視図である。図2は図1における溝形部材1を用いた床版(または覆工板などの版状パネル)を形成する場合の一形態を示す図である。   FIG. 1 is a perspective view of a floor slab bridge 4 using a channel member 1 formed by processing channel steel according to the first embodiment. FIG. 2 is a diagram showing an embodiment in the case of forming a floor slab (or a plate-like panel such as a lining plate) using the channel member 1 in FIG.

図1に示す床版橋4は、支間15m以下の橋梁に用いられる橋梁形式で、A矢印方向が橋軸方向であり、床版橋4は、橋軸方向に伸長する溝形鋼等の溝形部材1を橋軸直角方向に複数本平行に配設して構成される。すなわち、橋幅に対して溝形部材1一本あたりの上辺の幅は小さいから、この溝形部材1を複数平行に配設し、相互間を一体化して床版橋4を構成し、その上面にコンクリートまたはアスファルトよりなる舗装3を打設して路面を構成することになる。この路面を重量物である車両が走行することから溝形部材1には過大な荷重が作用し、したがって、溝形部材1を下側に撓ませる力や、溝形部材1相互を引き離す大小のせん断力が常時作用することになる。このため複数の溝形部材1の相互は強固に結合一体化されているのが望ましく、かつ、上方からの力に対して耐荷重が大きい構造が望ましい。
また、図示は省略するが、道路橋において桁の上に設置され、路面を構成する床版においても上記の床版橋4と同様の形態、性能が求められる。
The floor slab bridge 4 shown in FIG. 1 is a bridge type used for bridges with a span of 15 m or less. The arrow A direction is the bridge axis direction, and the floor slab bridge 4 is a groove of a grooved steel or the like extending in the bridge axis direction. A plurality of shape members 1 are arranged in parallel in a direction perpendicular to the bridge axis. That is, since the width of the upper side per groove member 1 is small with respect to the bridge width, a plurality of the groove members 1 are arranged in parallel, and the floor slab bridge 4 is formed by integrating each other. A pavement 3 made of concrete or asphalt is placed on the upper surface to form a road surface. Since a heavy vehicle travels on the road surface, an excessive load is applied to the groove member 1. Accordingly, the force that causes the groove member 1 to bend downward, and the large and small forces that separate the groove members 1 from each other. Shear force is always applied. For this reason, it is desirable that the plurality of channel-shaped members 1 are firmly coupled and integrated, and a structure having a large load resistance against the force from above is desirable.
Moreover, although illustration is abbreviate | omitted, the form and performance similar to said floor slab bridge 4 are calculated | required also in the floor slab which is installed on a girder in a road bridge and comprises a road surface.

このため本発明では、溶接、ボルト接合、補強板取付け作業などが不要な構成としている。すなわち、溝形部材1のウェブ12の側面5には、所定の間隔をあけて複数の開口部6が開設されており、橋軸方向に伸長する複数の溝形部材1を橋軸直角方向に平行に並べたとき、前記開口部6が橋軸直角方向の直線上に揃い、この各開口部6に棒状部材7を挿通して橋軸直角方向にせん断キーを構成しており、それにより溝形部材1の相互がずれないように強固に締結して床版橋4を構成している。棒状部材7は、鋼管、棒鋼、鉄筋などの何れの材料でもよい。   For this reason, in this invention, it is set as the structure which welding, bolt joining, a reinforcement board attachment operation | work, etc. are unnecessary. That is, the side surface 5 of the web 12 of the groove member 1 is provided with a plurality of openings 6 at predetermined intervals, and the plurality of groove members 1 extending in the bridge axis direction are arranged in a direction perpendicular to the bridge axis. When arranged in parallel, the openings 6 are aligned on a straight line in a direction perpendicular to the bridge axis, and a bar-like member 7 is inserted into each opening 6 to constitute a shear key in the direction perpendicular to the bridge axis. The slab bridge 4 is configured by being firmly fastened so that the shape members 1 do not deviate from each other. The rod-shaped member 7 may be any material such as a steel pipe, a steel bar, a reinforcing bar.

このように複数の溝形部材1の各開口部6に挿通した棒状部材7により各溝形部材1相互が結合されると共に、上方からの荷重に対して棒状部材7がせん断キーとして機能し、複数の溝形部材1相互に発生しようとするずれを防止して上面にたわみ差が生じないように構成するもので、したがって溝形部材1の耐荷力を増大することができ、溝形部材1に作用する荷重による溝形部材1の疲労破壊の恐れを少なくし、施工管理を容易・確実にできる。横方向に隣合う溝形部材1相互は、一方の溝形部材1におけるフランジ先端部の凸部(一部)と、他方の溝形部材1におけるウェブ12とフランジ基端部とのコーナー部に設けた切り込み部(支承部)とが噛み合うことで、コンクリートなどの経時硬化性材料8の打設時の漏洩が防止されている。図示の形態で、より確実に、コンクリートなどの経時硬化性材料8の打設時の漏洩を防止するために、図9および図10に示すように、横方向に隣合う溝形部材1間には、ゴムのような弾性材料17を押し潰し変形された状態で介在させて、コンクリートなどの経時硬化性材料8の打設時の漏洩を防止し、確実に充填されるようにしてもよい。   In this way, the rod-shaped members 1 are coupled to each other by the rod-shaped members 7 inserted through the openings 6 of the plurality of channel-shaped members 1, and the rod-shaped members 7 function as shear keys with respect to loads from above. The groove member 1 is configured so as to prevent a deviation from occurring between the plurality of groove members 1 so that a difference in deflection does not occur on the upper surface. Therefore, the load bearing force of the groove member 1 can be increased. The risk of fatigue breakage of the channel member 1 due to the load acting on the surface is reduced, and the construction management can be performed easily and reliably. The groove members 1 that are adjacent to each other in the lateral direction are at the convex portion (part) of the flange tip portion of one groove member 1 and the corner portion between the web 12 and the flange base end portion of the other groove member 1. Since the notched portion (supporting portion) provided is engaged, leakage at the time of placing the time-curable material 8 such as concrete is prevented. In order to prevent leakage at the time of placing the curable material 8 such as concrete more reliably in the form shown in the figure, as shown in FIG. 9 and FIG. The elastic material 17 such as rubber may be interposed in a state of being crushed and deformed to prevent leakage at the time of placing the curable material 8 such as concrete, and to be surely filled.

さらに、溝形部材1と棒状部材7の確実な一体化を図るため、隣合う該溝形部材1と棒状部材7との交差部分における溝形部材1のフランジが隣接する溝形部材1のウェブ12で閉塞することによって形成される空間(溝)25内部に、上部側のコンクリート充填孔11からコンクリートなどの経時硬化性材料8を充填する。この場合、溝形部材1の側方開口溝25aが隣接する溝形部材1のウェブ12で閉塞することによって形成される空間(溝)25内において、棒状部材7が貫通している溝形部材1長手方向の両側に所定の間隔をあけて仕切り板10を設ける構成としてもよい。   Further, in order to ensure the integration of the groove member 1 and the rod-shaped member 7, the web of the groove member 1 in which the flange of the groove member 1 at the intersection of the adjacent groove-shaped member 1 and the rod-shaped member 7 is adjacent. A space (groove) 25 formed by closing at 12 is filled with a time-curable material 8 such as concrete from the concrete filling hole 11 on the upper side. In this case, the groove-shaped member through which the rod-shaped member 7 penetrates in the space (groove) 25 formed by closing the side opening groove 25a of the groove-shaped member 1 with the web 12 of the adjacent groove-shaped member 1 It is good also as a structure which provides the partition plate 10 at predetermined intervals on the both sides of 1 longitudinal direction.

この仕切り板10で区画された内側に、溝形部材1の上面側の上フランジ33aに形成した経時硬化性材料充填孔11または側方開口部6から、前記の経時硬化性材料8を充填する。こうして経時硬化性材料8を介して溝形部材1と棒状部材7が一体化され、溝形部材1に作用するせん断力に対するキー機能は一層向上する。また、経時硬化性材料8は仕切り板10と溝形部材1が隣接する溝形部材1のウェブ12で閉塞することによって形成される溝内(空間)の必要箇所のみに部分的に充填されるから、溝形部材1の全長に渡って充填する場合に比べ、溝形部材1の重量をできるだけ軽くすることができると共に、経時硬化性材料8の使用量を低減でき、さらに、軽量であるために工場にて溝形部材1を結合して床版ユニット(または覆工板ユニット等の版状パネルユニット)14を製作したうえ現場に搬送する上で好都合である。   The time-curable material 8 is filled into the inside partitioned by the partition plate 10 from the time-curable material filling hole 11 or the side opening 6 formed in the upper flange 33a on the upper surface side of the channel member 1. . Thus, the groove-shaped member 1 and the rod-shaped member 7 are integrated via the time-curable material 8, and the key function against the shearing force acting on the groove-shaped member 1 is further improved. Further, the time-curable material 8 is partially filled only in necessary portions in the groove (space) formed by the partition plate 10 and the groove member 1 being closed by the web 12 of the adjacent groove member 1. Therefore, the weight of the groove-shaped member 1 can be reduced as much as possible as compared with the case where the entire length of the groove-shaped member 1 is filled, and the amount of the time-curable material 8 can be reduced, and further, the weight is light. It is convenient to manufacture the floor slab unit (or plate-like panel unit such as a lining plate unit) 14 by connecting the groove-shaped member 1 to the factory and transport it to the site.

溝形部材1は、単体の溝形鋼を複数本用いて施工の現場で棒状部材7を用いて相互に接合して床版2を構築してもよい。また、複数の溝形部材1を予め一体化した床版ユニット14を製作し、複数の床版ユニット14を施工現場で接合してもよく、この方法は橋幅の広い床版2を容易に構築できる(詳細は後述する)。なお、図1において、床版橋4の幅員方向両側部には、溝形鋼の溝を上向きに配置して側溝18が構成されており、さらにその外側に溝形鋼の溝を下向きに配置して地覆19が構成されており、地覆19には高欄20が立設固定されている。この側溝18、地覆19などは現場でコンクリートを打設することにより、製作してもよい。   The grooved member 1 may be constructed by using a plurality of single grooved steels and mutually joining them using a bar-shaped member 7 at the construction site. Further, a floor slab unit 14 in which a plurality of channel members 1 are integrated in advance may be manufactured, and the plurality of floor slab units 14 may be joined at a construction site. Can be constructed (details will be described later). In FIG. 1, grooved steel grooves are disposed upward on both sides in the width direction of the floor slab bridge 4 to form side grooves 18, and further, grooved steel grooves are disposed downward on the outer side thereof. Thus, a ground cover 19 is configured, and a rail 20 is erected and fixed to the ground cover 19. The side grooves 18, the ground cover 19 and the like may be manufactured by placing concrete on site.

前記の弾性材料17としては、例えば、ゴムあるいは合成樹脂のような弾性を有する材質のものを使用するとよい。前記の弾性材料17は、構造上必要な棒状部材7を利用して弾性的に押し潰し変形され、弾性材料17が設置されている区間では、弾性材料17が雨水の侵入を防ぐ役割も果たすことができる。フランジ幅方向先端部に側方開口溝を有する溝形部材1とする場合には、弾性材料17は、経時硬化性材料充填孔11の部分では設けないので、経時硬化性材料充填孔11の軸方向に両側において、経時硬化性材料8と弾性材料17が設けられている部分が重複するようにして、雨水の侵入を防ぐようにし、経時硬化性材料充填孔11より軸方向に位置をずらして仕切り板10の設置位置も設定される。   As the elastic material 17, for example, a material having elasticity such as rubber or synthetic resin may be used. The elastic material 17 is elastically crushed and deformed using the rod-like member 7 necessary for the structure, and the elastic material 17 also serves to prevent rainwater from entering in the section where the elastic material 17 is installed. Can do. When the groove-shaped member 1 having a side opening groove at the front end portion in the flange width direction is used, the elastic material 17 is not provided in the portion of the time-curable material filling hole 11. On both sides in the direction, the portions where the time-curing material 8 and the elastic material 17 are provided overlap so as to prevent rainwater from entering, and the position is shifted in the axial direction from the time-curing material filling hole 11. The installation position of the partition plate 10 is also set.

また、本発明に用いられる溝形部材1は、熱間圧延による方法によって製造された市販の溝形鋼を用い、適宜切削加工して切り込み部あるいは凹部等の支承部あるいは凸部等の被支承部を切削加工により設けると安価でよい。   In addition, the channel member 1 used in the present invention is a commercially available channel steel manufactured by a method by hot rolling, and is appropriately cut and supported such as a support portion such as a cut portion or a concave portion or a supported portion such as a convex portion. If the part is provided by cutting, it may be inexpensive.

本発明では、図2の複数本敷き並べた溝形部材1に横方向に棒状部材7を挿通すると共に、図2(b)に矢印Aで示すように各溝形部材1を中央部に向かって押付ける(または、引き寄せる)ように、棒状部材7に何らかの方法で引張力を加え、これを溝形部材1のウェブ12の側面5に定着することで、隣接する溝形部材1の接触面にプレストレス(接触面に垂直なプレストレス)が導入され、これにより隣接する溝形部材1の上下のフランジ33a,33bの側面は、(または、これらの間に介在された弾性材料17を押圧して弾性変形させて)圧着した状態で接合する。この状態でコンクリートなどの経時硬化性材料8を溝形部材1の空間(溝)25内に充填し、工場製作される床版ユニット14、または覆工板を一体化する。   In the present invention, the rod-shaped member 7 is inserted in the lateral direction into the groove-shaped members 1 arranged in a plurality of lines in FIG. 2, and each groove-shaped member 1 is directed toward the center as indicated by an arrow A in FIG. The contact surface of the adjacent channel member 1 is applied by applying a tensile force to the rod member 7 by some method so as to be pressed (or pulled) and fixed to the side surface 5 of the web 12 of the channel member 1. Prestress (prestress perpendicular to the contact surface) is introduced to the side surfaces of the upper and lower flanges 33a and 33b of the adjacent groove-shaped member 1 (or press the elastic material 17 interposed between them). And then elastically deformed) and bonded in a crimped state. In this state, the time-curable material 8 such as concrete is filled in the space (groove) 25 of the groove-shaped member 1, and the floor slab unit 14 manufactured by the factory or the lining board is integrated.

前記のように棒状部材7に引張力が導入され、溝形部材1のウェブ12の側面5に定着されることで、隣接する溝形部材1の上下のフランジ33a,33b側面(またはこれらの間の弾性材料17を介した)接触面にはプレストレスが導入された状態が保持され、隣接する溝形部材1の上下のフランジ33の側面が面接触した状態が保持され、密着面の摩擦接合により荷重を多少は水平方向に分散できる、また、弾性材料17が介在されていることにより、溝形部材1に荷重(輪荷重)が作用した際の溝形部材1相互のズレを生じてもこれを滑らかにすることができる。さらに、熱間圧延による市販の溝形鋼を使用すると、寸法精度が高いので、構造物である床版、または覆工板の寸法精度が向上する。さらに、従来の方法でプレストレスを導入する場合は、PC鋼材の両端部を緊張した上で定着するから、PC鋼材、専用ジャッキなど緊張器具、定着具などが必要となるが、本発明では容量の小さい汎用の工具を用いて作業するために、架設手順も簡略になり、作業の安全性も向上する。また、溝形部材1にプレストレスを伝達するための棒状部材7の定着部は、導入プレストレスに耐え得るものであればよく、いかなる形状であってもよい。   As described above, the tensile force is introduced into the rod-shaped member 7 and is fixed to the side surface 5 of the web 12 of the channel member 1 so that the side surfaces of the upper and lower flanges 33a and 33b of the adjacent channel member 1 (or between them). The state where the prestress is introduced is maintained on the contact surface (through the elastic material 17), and the state where the side surfaces of the upper and lower flanges 33 of the adjacent groove-shaped member 1 are in surface contact is maintained. The load can be somewhat dispersed in the horizontal direction, and the elastic material 17 is interposed, so that even when the load (ring load) is applied to the groove member 1, the groove members 1 are displaced from each other. This can be smoothed. Furthermore, when commercially available channel steel by hot rolling is used, since the dimensional accuracy is high, the dimensional accuracy of the floor slab or the lining plate which is a structure is improved. Further, when prestressing is introduced by a conventional method, since both ends of the PC steel are fixed and then fixed, a tensioning device such as PC steel and a dedicated jack, a fixing tool, etc. are required. Therefore, the construction procedure is simplified and the safety of the work is improved. Further, the fixing portion of the rod-like member 7 for transmitting the prestress to the groove member 1 may be any shape as long as it can withstand the introduced prestress.

本発明において複数本敷き並べた溝形部材1に幅方向にプレストレスを導入するには、ナット22を回転させるか、工場にて溝形部材1のウェブ12の側面5にジャッキを当てるか、または工事現場で、溝形部材1単体または床版ユニットの自重を利用してプレストレスを導入するので、簡単かつ安全にプレストレスを導入することができる。導入プレストレスは、溝形部材1相互の継ぎ目1箇所当り、例えば1〜2トンでよい。したがって、PC構造のように本格的なプレストレス導入器具が不要で、棒状部材7の鋼材の破断の恐れがないなど、施工時の安全性も高い利点がある。
棒状部材7の定着金具は、棒状部材7に導入されたプレストレスを保持することができればよく、ナット22、クサビ24(図4参照)などいかなる形状であってもよい。なお、溝形部材1の断面が大きくなると重量も重く(数トン程度)なるので、所定の位置に溝形鋼を適宜加工した溝形部材1を設置することにより、溝形部材1とその設置支承部との横方向の摩擦抵抗力が、前記プレストレス力よりも勝るようになるので、溝形部材1を設置するだけで、その自重を利用して、前記プレストレスを付与することができる。
In order to introduce prestress in the width direction to the groove-shaped members 1 arranged in a plurality in the present invention, the nut 22 is rotated, or a jack is applied to the side surface 5 of the web 12 of the groove-shaped member 1 at the factory, Alternatively, prestress can be easily and safely introduced at the construction site because the prestress is introduced by utilizing the weight of the single channel member 1 or the floor slab unit. The introduction prestress may be, for example, 1 to 2 tons per seam between the groove members 1. Therefore, there is an advantage that the safety at the time of construction is high such that a full-scale prestress introduction device is not required unlike the PC structure, and there is no fear of the steel material of the rod-shaped member 7 being broken.
The fixing bracket of the rod-shaped member 7 may be any shape such as a nut 22 and a wedge 24 (see FIG. 4) as long as the prestress introduced into the rod-shaped member 7 can be retained. In addition, since the weight will become heavier (several tons) when the cross section of the groove member 1 becomes large, the groove member 1 and its installation are installed by installing the groove member 1 in which groove steel is appropriately processed at a predetermined position. Since the frictional resistance force in the lateral direction with respect to the support portion is greater than the prestressing force, the prestress can be applied by using the weight of the grooved member 1 simply by installing the grooved member 1. .

また、本発明におけるプレストレスの導入方法は、前述のようにナット22の回転による方法、溝形部材1にジャッキなどにより荷重を加える方法などの他、棒状部材7をバーナー、ヒーターなどで一時的に熱して、伸長させるように膨張させ、棒状部材7を溝形部材1に定着した後に、棒状部材7の温度を常温に戻してプレストレスを導入する方法などを用いても良い。   In addition to the method of rotating the nut 22 as described above and the method of applying a load to the groove-shaped member 1 with a jack or the like as described above, the prestress introduction method in the present invention may be temporarily performed by using a burner, a heater, or the like. Alternatively, after the rod-like member 7 is fixed to the groove-shaped member 1 by being heated and expanded so as to be elongated, the temperature of the rod-like member 7 is returned to room temperature to introduce prestress.

以下に、棒状部材7を用いて溝形部材1相互にプレストレスを導入して結合するための具体的手段を図2を参照して簡単に説明すると、例えば、次のような(1)〜(2)の方法がある。
(1)図2(b)において、棒状部材7の両端に取り付けたナット22を回転させて棒状部材7に引張力を作用させ、端部の溝形部材1のウェブ12側面に定着するようにして、溝形部材1相互にプレストレスを導入して結合する方法。
(2)図2(a)において、ナット22を一端側に装着した棒状鋼材7を、並列して設置された溝形部材1の開口部6から挿入して、前記ナット22を開口部6周囲の溝形部材1の外面に装着した状態で、予め並列配置された溝形部材1の横方向からジャッキ等により押圧し、棒状部材7の両端をナット22、またはクサビなどの定着具を用いて定着し、ジャッキ等による押圧荷重を開放して、溝形部材1床版相互に渡ってプレストレスを導入する方法。
前記のいずれの方法の場合も、開口部6より棒状部材7の外径は小さく、ナット22の外径よりもウェブ12の側面5に設ける開口部6の内径が小さく設定されている。なお、棒状部材7は必要に応じ、上下方向にも配置して、例えば1箇所当たり間隔をおいて4本配置するようにしてもよい。
Hereinafter, specific means for introducing the prestress between the groove-shaped members 1 using the rod-shaped member 7 and joining them together will be briefly described with reference to FIG. There is a method (2).
(1) In FIG. 2 (b), the nuts 22 attached to both ends of the rod-like member 7 are rotated to apply a tensile force to the rod-like member 7 so as to be fixed to the side surface of the web 12 of the channel member 1 at the end. Then, a method of introducing prestress between the groove-shaped members 1 and coupling them.
(2) In FIG. 2 (a), a rod-like steel material 7 fitted with a nut 22 on one end side is inserted from the opening 6 of the groove-shaped member 1 installed in parallel, and the nut 22 is placed around the opening 6 In a state of being mounted on the outer surface of the groove-shaped member 1, the rod-shaped member 7 is pressed with a jack or the like from the lateral direction of the groove-shaped members 1 arranged in advance in advance, and both ends of the rod-shaped member 7 are used using a fixing tool such as a nut 22 or wedge A method in which prestress is introduced between the groove-shaped members 1 floor slab by fixing and releasing the pressing load by a jack or the like.
In any of the above methods, the outer diameter of the rod-like member 7 is smaller than that of the opening 6, and the inner diameter of the opening 6 provided on the side surface 5 of the web 12 is set smaller than the outer diameter of the nut 22. In addition, you may make it arrange | position the bar-shaped member 7 also to an up-down direction as needed, for example, may arrange | position four at intervals per place.

図3は、棒状部材7の定着具の2例を示したものである。図4(a)、(b)は、棒状部材7の端部に、外周に、図3(a)(b)に示すネジ26(雄ねじ部)、または図3(c)(d)に示すネジ節21(異径雄ねじ部)を備えた雄ねじ軸部が設けられており、これに螺合するナット22および座金を組合せた例を示している。図4(c)、(d)は、截頭円錐状の棒状鋼材挿通穴およびクサビ定着用孔を有し、かつ溝形部材1の側面に係合する支圧プレート24aと、分割型のクサビ24を用いた形態を示したものである。   FIG. 3 shows two examples of the fixing member of the rod-like member 7. 4 (a) and 4 (b) show the end of the rod-like member 7 on the outer periphery, the screw 26 (male screw portion) shown in FIGS. 3 (a) and 3 (b), or FIGS. 3 (c) and 3 (d). An example is shown in which a male screw shaft portion provided with a screw node 21 (different diameter male screw portion) is provided, and a nut 22 and a washer screwed together are combined. 4 (c) and 4 (d) show a rod-shaped steel rod insertion hole and a wedge fixing hole having a frustoconical shape, and a support plate 24a that engages with the side surface of the channel member 1, and a split type wedge. The form using 24 is shown.

次に、図2(c)に示すような床版または覆工板用の版状パネルを構築する場合、図2(a)に示すように、現場にて溝形部材1を複数本並べて架設し、横つなぎ用の棒状部材7に引張力を与えることにより結合する形態としてもよい。現場施工する場合、溝形部材1のウェブ12の側面5には開口部6が形成されていて、この開口部6から一端側にナット22を装着した棒状部材7を挿通する。その後、他端側に装着されるナット22を回転して締め込んで、棒状部材7に引張力を与え、溝形部材1のウェブ12の側面に定着する。
棒状部材7の直上部付近において溝形部材1の上フランジ33aの上面には、独立した経時硬化性材料充填孔11または、上フランジ33aの側端部に設けられた側方開口溝が隣接する溝形部材1のウェブ12またはフランジ33で閉塞することによって形成される充填孔11が形成されていて、この経時硬化性材料充填孔11からコンクリートなどの経時硬化性材料8を隣合う溝形部材1相互によって形成される空間(溝)25内に充填する。
経時硬化性材料8は、隣合う溝形部材1相互によって形成される空間(溝)25内において棒状部材7と一体化していれば、隣合う溝形部材1相互によって形成される空間(溝)25内の部材全長の空間(溝)25を埋め尽くさなくてもよく、棒状部材7の周囲の一部領域のみであって構わない。また、横つなぎ部材となる棒状部材7は、長手方向全長にわたって設ける必要はなく、一群の棒状部材7の中心間の間隔が3m以下となるように配置すればよい。各位置での配置本数、段数は、横つなぎ位置に作用するせん断力、ならびに曲げモーメントに対して、棒状部材7のみでせん断力に抵抗できる断面を確保し、なおかつ曲げモーメントに対しては隣合う溝形部材1相互間の空間(溝)25内部に充填されたコンクリートなどの経時硬化性材料8と棒状部材7で、圧縮力は経時硬化性材料8で、引張力は棒状部材7で分担し、それぞれが十分な強度を確保できるように数量、配置を決定すればよい。
Next, when building a plate-like panel for a floor slab or a lining board as shown in FIG. 2 (c), a plurality of channel members 1 are installed side by side at the site as shown in FIG. 2 (a). And it is good also as a form couple | bonded by giving the tensile force to the rod-shaped member 7 for a horizontal connection. In the case of construction at the site, an opening 6 is formed in the side surface 5 of the web 12 of the channel member 1, and a rod-like member 7 fitted with a nut 22 on one end side is inserted through the opening 6. Thereafter, the nut 22 mounted on the other end side is rotated and tightened to give a tensile force to the rod-shaped member 7 and fix to the side surface of the web 12 of the channel-shaped member 1.
In the vicinity of the upper portion of the rod-shaped member 7, the upper surface of the upper flange 33 a of the groove-shaped member 1 is adjacent to an independent time-curable material filling hole 11 or a side opening groove provided at a side end of the upper flange 33 a.

It is not necessary to fill the space (groove) 25 of the entire length of the member in 25, and it may be only a partial region around the rod-shaped member 7. Moreover, the rod-shaped member 7 which becomes a horizontal connecting member does not need to be provided over the entire length in the longitudinal direction, and may be arranged so that the distance between the centers of the group of rod-shaped members 7 is 3 m or less. The number of arrangements and the number of steps at each position ensure a cross section that can resist the shearing force with only the rod-like member 7 against the shearing force and bending moment acting on the horizontal connecting position, and is adjacent to the bending moment. The time-hardening material 8 such as concrete and the rod-shaped member 7 filled in the space (groove) 25 between the groove-shaped members 1 and the rod-shaped member 7 share the compressive force with the time-curable material 8 and the tensile force with the rod-shaped member 7. The quantity and arrangement may be determined so that each can secure sufficient strength.
