Description

本発明は、暗渠や橋梁などに用いることが可能なコンクリート組立構造体およびその施工方法に関する。   The present invention relates to a concrete assembly structure that can be used for underdrains, bridges, and the like, and a construction method thereof.
暗渠や橋梁などのコンクリート構造体として、現場で型枠を組んでコンクリートを打設する現場施工によるものや、ボックス状にしたプレキャスト製品を現場で組み立てるものが知られている。プレキャスト製品を現場で組み立てるものでは、現場施工によるものと比較して、現場での施工性に優れているものの、大型の構造物の場合、運搬時の寸法上および重量上の制約を受けやすい。   As concrete structures such as culverts and bridges, there are known ones based on on-site construction in which concrete is placed by laying a formwork on site, and ones in which precast products in the form of boxes are assembled on-site. When precast products are assembled on-site, they are more easily installed on site than on-site construction, but large structures tend to be subject to dimensional and weight restrictions during transportation.
そこで、この種のコンクリート構造体では、従来、プレキャスト製品を分割型として、現場へ運搬し、組み立てるものや、プレキャスト部材と現場打ちコンクリートとを組み合わせて構築するものなどが開発されている。   Therefore, in this type of concrete structure, a precast product has been developed as a divided type, which is transported to the site and assembled, or constructed by combining a precast member and a cast-in-place concrete.
例えば、特許文献1には、幅方向両側に設けられ立壁部の下部に横方向の自立脚部を一体に有するプレキャストコンクリート製の側壁部材と、これら側壁部材の立壁部の上部間に掛け渡されるプレキャストコンクリート製の型枠部材と、この型枠部材と型枠部材上にコンクリートを打設して形成された打設コンクリート部とからなる頂版部と、自立壁部の内端に下向き段部が形成され、幅方向両側の自立脚部間に底版部とを備えたコンクリート組立構造体が開示されている。   For example, in Patent Document 1, a side wall member made of precast concrete which is provided on both sides in the width direction and integrally has a self-standing leg portion in the lateral direction at the lower portion of the standing wall portion, and the upper portion of the standing wall portion of these side wall members are spanned. A form plate member made of precast concrete, a top plate portion formed by placing the concrete member on the mold member and the formwork member, and a downward stepped portion at the inner end of the self-supporting wall portion A concrete assembly structure having a bottom plate portion between self-standing leg portions on both sides in the width direction is disclosed.
また、特許文献2には、側壁と底面壁を有する左右の分割L型構造体とその底面壁間の現場打ちコンクリート底面壁と、左右の分割L型構造体に載置の分割コンクリート頂版からなり、側壁上端面と底面壁端面に鉄筋出しを設け、側壁上端面に載置の分割コンクリート頂版の端部下端面にスリーブを設けて鉄筋出しを接続し、左右の底面壁間の現場打ちコンクリート内に鉄筋を設けて底面壁端面の鉄筋出しと接続したボックス型ガレージが開示されている。   Further, Patent Document 2 discloses a left and right divided L-type structure having side walls and a bottom wall, a cast-in-place concrete bottom wall between the bottom walls, and a divided concrete top plate placed on the left and right divided L-type structures. In the cast-in-place concrete between the left and right bottom walls, reinforcing bars are provided on the upper end surface of the side wall and the end surface of the bottom wall, and a sleeve is provided on the lower end surface of the split concrete top plate placed on the upper end surface of the side wall. There is disclosed a box-type garage in which a reinforcing bar is provided and connected to the reinforcing bar on the end face of the bottom wall.
ところで、水路と道路や道路と道路などが交差する施工現場では、その交差角が直角以外の斜角となることが多い。そこで、このような施工現場に対応可能な門形ブロックを製造する技術として、例えば特許文献3には、平面視下で前後動、左右動または旋回して互いに連結可能な、左右端部中子と複数の調整中子と、前後妻板と前後端部妻板からなり、左右端部中子は、フレーム上に設けた中子端部と、底面部材を挟んで前後左右に摺動して固定可能に立設した鋭角状端部を有する側板からなり、任意数の調整中子と組付け、調整中子と左右端部中子に妻板と端部妻板を装着し、所要幅員と左右の水路壁が任意角度に形成可能な門形ブロック製造用型枠が開示されている。   By the way, at construction sites where waterways and roads or roads and roads intersect, the intersection angle is often an oblique angle other than a right angle. Therefore, as a technique for manufacturing such a gate-shaped block that can be applied to the construction site, for example, Patent Document 3 discloses a left and right end core that can be connected to each other by moving back and forth, moving left and right, or turning in a plan view. And a plurality of adjustment cores, front and rear end plates and front and rear end end plates, and the left and right end cores can be fixed by sliding back and forth and left and right across the core end provided on the frame and the bottom member It consists of a side plate with an acute-angled end standing upright, assembled with an arbitrary number of adjustment cores, fitted with adjustment plates and left and right end cores with end plates and end end plates, required width and left and right channel walls Is disclosed in a portal block manufacturing form that can be formed at an arbitrary angle.

特許文献1に記載のコンクリート組立構造体では、頂版部を現場打ちするため、生コンクリートの使用量が多く、養生日数も多くなる。また、側壁部材の立壁部の上部間に型枠部材を掛け渡した後、この型枠部材上に鉄筋トラスを現場にて配筋する必要があるため、施工に多くの時間を要する。   In the concrete assembly structure described in Patent Document 1, since the top plate portion is hit in the field, the amount of ready-mixed concrete used is large and the number of days of curing is also increased. In addition, since it is necessary to place a reinforcing bar truss on the formwork member after the formwork member is bridged between the upper portions of the standing wall portions of the side wall member, a lot of time is required for the construction.
また、特許文献2に記載のボックス型ガレージ構造体では、分割コンクリート頂版が側壁上に載置され、この分割コンクリート頂版の端部下端面にスリーブを設け、側壁上端面に設けた鉄筋出しをこのスリーブに挿入し、モルタルを充填して固化して接合するだけであるため、連結箇所の強度が弱い。   Moreover, in the box-type garage structure described in Patent Document 2, the divided concrete top plate is placed on the side wall, a sleeve is provided on the lower end surface of the end portion of the divided concrete top plate, and the reinforcing bar provided on the upper end surface of the side wall is provided. Since it is only inserted into this sleeve, filled with mortar, solidified, and joined, the strength of the connecting portion is weak.
また、特許文献3に記載の門形ブロック製造用型枠では、交差角に応じて門形ブロックを形成することが可能であるものの、1つの門形ブロックごとに型枠を調整する作業は非常に複雑であり、作業に多くの時間を要する。   Further, in the portal block manufacturing form described in Patent Document 3, it is possible to form the portal block according to the crossing angle, but the work of adjusting the mold for each portal block is very difficult. It is complicated and takes a lot of time to work.
そこで、本発明においては、施工性に優れ、側壁部材と頂版部との連結箇所の強度に優れたコンクリート組立構造体およびその施工方法を提供することを目的とする。   Then, in this invention, it aims at providing the concrete assembly structure excellent in workability | operativity, and excellent in the intensity | strength of the connection location of a side wall member and a top plate part, and its construction method.
本発明のコンクリート組立構造体は、対面配置される対のプレキャストコンクリート製の側壁部材であり、立壁部の上部に鉄筋を突出させた側壁部材と、対の側壁部材の上部間にそれぞれ隅角部を空けて掛け渡されるプレキャストコンクリート製の頂版部材であり、隅角部に側壁部材の上部の鉄筋と連結される鉄筋を突出させた頂版部材と、隅角部にコンクリートを打設して形成された打設コンクリート部とを含むものである。   The concrete assembly structure of the present invention is a pair of precast concrete side wall members arranged face-to-face, each having a corner portion between a side wall member having a reinforcing bar projecting from the upper portion of the standing wall portion and the upper portion of the pair of side wall members. A top plate member made of precast concrete that is spanned with a gap between the top plate member that protrudes a reinforcing bar that is connected to the reinforcing bar on the upper side of the side wall member at the corner portion, and concrete is placed at the corner portion. And a cast-in concrete part formed.
また、本発明のコンクリート組立構造体の施工方法は、立壁部の上部に鉄筋を突出させた対のプレキャストコンクリート製の側壁部材を対面配置すること、プレキャストコンクリート製の頂版部材であり、側壁部材の上部の鉄筋と連結される鉄筋を突出させた頂版部材を、対の側壁部材の上部間にそれぞれ隅角部を空けて掛け渡すこと、頂版部材の鉄筋と側壁部材の鉄筋とを連結すること、隅角部にコンクリートを打設して打設コンクリート部を形成することを含む。   Further, the method for constructing a concrete assembly structure of the present invention includes a pair of precast concrete side wall members in which reinforcing bars protrude from the upper portion of the standing wall portion, a precast concrete top plate member, and a side wall member The top plate member that protrudes the reinforcing bar connected to the upper reinforcing bar is spanned between the upper parts of the pair of side wall members with a corner between them, and the reinforcing member of the top member and the reinforcing member of the side wall member are connected. Doing, and placing concrete in a corner portion to form a cast concrete portion.
本発明のコンクリート組立構造体によれば、側壁部材および頂版部材がプレキャストコンクリート製であり、施工現場においては、頂版部材を対の側壁部材の上部間にそれぞれ隅角部を空けて掛け渡し、頂版部材の鉄筋と側壁部材の鉄筋とを連結し、隅角部にコンクリートを打設すれば良いため、短時間での施工が可能となり、施工性が良い。また、頂版部材と側壁部材とがそれぞれから突出させた鉄筋により連結され、コンクリートにより一体化されて剛結されているため、側壁部材と頂版部材との接合強度が優れている。   According to the concrete assembly structure of the present invention, the side wall member and the top plate member are made of precast concrete, and at the construction site, the top plate member is spanned between the upper portions of the pair of side wall members with a corner portion therebetween. Since it is only necessary to connect the reinforcing bar of the top plate member and the reinforcing bar of the side wall member and to place concrete in the corner portion, the construction can be performed in a short time and the workability is good. Moreover, since the top plate member and the side wall member are connected by reinforcing bars protruding from each other, and are integrated and rigidly connected with concrete, the bonding strength between the side wall member and the top plate member is excellent.
ここで、対の側壁部材は、それぞれ立壁部の内面側に突出させた張り出し受け部を有するものであり、頂版部材は、張り出し受け部上に載置されるものであることが望ましい。これにより、側壁部材の立壁部の上方が空くため、側壁部材の立壁部の配筋を上方へ延長して突出させた鉄筋と、張り出し受け部上に載置された頂版部材から突出させた鉄筋とを連結してコンクリートにより一体化することができる。   Here, each of the pair of side wall members has an overhang receiving portion that protrudes toward the inner surface side of the standing wall portion, and the top plate member is preferably placed on the overhang receiving portion. Thereby, since the upper part of the standing wall portion of the side wall member is vacant, the reinforcing bar of the side wall member is protruded by extending upward and the top plate member placed on the overhang receiving portion. It can be integrated with concrete by connecting the reinforcing bars.
また、本発明のコンクリート組立構造体は、対の側壁部材が、それぞれ張り出し受け部上に、上方へ突出させた鉄筋を有するものであり、頂版部材が、張り出し受け部上の鉄筋が挿入される空隙部を有するものであることが望ましい。これにより、頂版部材をその空隙部に側壁部材の張り出し受け部上の鉄筋が挿入されるように配置し、空隙部にモルタルなどの充填材を注入して固結することで、偶角部の剛性がより高いものとなる。   In the concrete assembly structure of the present invention, the pair of side wall members each have a reinforcing bar protruding upward on the overhang receiving portion, and the top plate member is inserted with the reinforcing bar on the overhang receiving portion. It is desirable to have a void portion. Accordingly, the top plate member is arranged so that the reinforcing bar on the overhang receiving portion of the side wall member is inserted into the gap portion, and a filler such as mortar is injected into the gap portion and solidified, so that the even angle portion The rigidity becomes higher.
また、本発明のコンクリート組立構造体は、斜角に施工する場合には、頂版部材が、掛け渡し方向に沿った側面が対の側壁部材の立壁部の外面に対して斜め方向に形成されたものであることが望ましい。これにより、頂版部材のみを斜角に対応する型枠により形成すれば良く、側壁部材については通常の型枠により形成することが可能となる。   Further, when the concrete assembly structure of the present invention is constructed at an oblique angle, the top plate member is formed such that the side surface along the extending direction is inclined with respect to the outer surface of the standing wall portion of the pair of side wall members. It is desirable that Thereby, only the top plate member may be formed by a mold corresponding to the oblique angle, and the side wall member can be formed by a normal mold.
ここで、頂版部材から突出させた鉄筋は、対の側壁部材の立壁部の外面に対して斜め方向に配設されたものであり、側壁部材から突出させた鉄筋は、頂版部材から斜め方向に突出させた鉄筋に沿う方向に配設されたものであることが望ましい。これにより、頂版部材の掛け渡し方向に沿った配筋をそのまま斜め方向に延長して突出させた鉄筋と、頂版部材から斜め方向に突出させた配筋とを連結してコンクリートにより一体化することができる。   Here, the reinforcing bar protruded from the top plate member is disposed obliquely with respect to the outer surface of the standing wall portion of the pair of side wall members, and the reinforcing bar protruded from the side wall member is inclined from the top plate member. It is desirable that it is disposed in a direction along the reinforcing bar protruding in the direction. As a result, the reinforcing bar along the direction of the top plate member extending in the diagonal direction is directly connected to the reinforcing bar that protrudes diagonally from the top plate member and integrated by concrete. can do.
また、側壁部材の鉄筋および頂版部材の鉄筋は、それぞれ側壁部材および頂版部材からループ状に突出させたものであることが望ましい。これにより、側壁部材の鉄筋および頂版部材の鉄筋が、それぞれ側壁部材および頂版部材に強固に位置決めされて固定されているので、側壁部材と頂版部材との接合強度がさらに向上する。   Moreover, it is desirable that the reinforcing bars of the side wall member and the reinforcing member of the top plate member protrude from the side wall member and the top plate member in a loop shape, respectively. Thereby, since the reinforcing bar of the side wall member and the reinforcing bar of the top plate member are firmly positioned and fixed to the side wall member and the top plate member, respectively, the bonding strength between the side wall member and the top plate member is further improved.
(1)対面配置される対のプレキャストコンクリート製の側壁部材であり、立壁部の上部に鉄筋を突出させた側壁部材と、対の側壁部材の上部間にそれぞれ隅角部を空けて掛け渡されるプレキャストコンクリート製の頂版部材であり、隅角部に側壁部材の上部の鉄筋と連結される鉄筋を突出させた頂版部材と、隅角部にコンクリートを打設して形成された打設コンクリート部とを含む構成により、短時間での施工が可能となり、施工性が良い。また、頂版部材と側壁部材とがそれぞれから突出させた鉄筋により連結され、コンクリートにより一体化されて剛結されているため、側壁部材と頂版部材との接合強度が優れている。 (1) A pair of precast concrete side wall members arranged face-to-face, and spanned between a side wall member having a reinforcing bar projecting from an upper part of a standing wall part and an upper part of the pair of side wall members with a corner portion therebetween. A top plate member made of precast concrete, and a top plate member in which a reinforcing bar connected to a reinforcing bar on the upper side of the side wall member is projected at a corner portion, and a cast concrete formed by placing concrete at the corner portion By the structure including the part, construction in a short time becomes possible, and workability is good. Moreover, since the top plate member and the side wall member are connected by reinforcing bars protruding from each other, and are integrated and rigidly connected with concrete, the bonding strength between the side wall member and the top plate member is excellent.
(2)対の側壁部材が、それぞれ立壁部の内面側に突出させた張り出し受け部を有するものであり、頂版部材が、張り出し受け部上に載置されるものであることにより、側壁部材の立壁部の配筋を上方へ延長して突出させた鉄筋と、張り出し受け部上に載置された頂版部材から突出させた鉄筋とが連結されてコンクリートにより一体化されるので、側壁部材と頂版部材との接合強度がさらに優れたコンクリート組立構造体が得られる。 (2) The pair of side wall members each have an overhang receiving portion that protrudes toward the inner surface side of the standing wall portion, and the top plate member is placed on the overhang receiving portion, whereby the side wall member Since the reinforcing bars protruding from the upright wall of the upright wall are projected upward and the reinforcing bars protruding from the top plate placed on the overhang receiving part are connected and integrated by the concrete, the side wall member A concrete assembly structure having a further improved bonding strength between the top plate member and the top plate member is obtained.
(3)対の側壁部材が、それぞれ張り出し受け部上に、上方へ突出させた鉄筋を有するものであり、頂版部材が、張り出し受け部上の鉄筋が挿入される空隙部を有するものであることにより、頂版部材をその空隙部に側壁部材の張り出し受け部上の鉄筋が挿入されるように配置し、空隙部にモルタルなどの充填材を注入して固結することで、隅角部の剛性がより高いものとなる。 (3) The pair of side wall members each have a reinforcing bar protruding upward on the overhang receiving portion, and the top plate member has a gap portion into which the reinforcing bar on the overhang receiving portion is inserted. By arranging the top plate member so that the reinforcing bar on the overhang receiving portion of the side wall member is inserted into the gap portion, and filling the gap portion with a filler such as mortar, the corner portion The rigidity becomes higher.
(4)頂版部材が、掛け渡し方向に沿った側面が対の側壁部材の立壁部の外面に対して斜め方向に形成されたものであることにより、頂版部材のみを斜角に対応する型枠により形成すれば良く、側壁部材については通常の型枠により形成することが可能となるので、斜角に施工する場合であっても型枠を安価に構成することが可能となり、頂版部材を容易かつ安価に形成することが可能となる。 (4) Since the top plate member is formed such that the side surface along the extending direction is inclined with respect to the outer surface of the standing wall portion of the pair of side wall members, only the top plate member corresponds to the oblique angle. What is necessary is just to form by a formwork, and since it becomes possible to form a side wall member by a normal formwork, even if it is a case where it constructs at an oblique angle, it becomes possible to constitute a formwork at low cost, and a top plate The member can be easily and inexpensively formed.
(5)頂版部材から突出させた鉄筋が、対の側壁部材の立壁部の外面に対して斜め方向に配設されたものであり、側壁部材から突出させた鉄筋が、頂版部材から斜め方向に突出させた鉄筋に沿う方向に配設されたものであることにより、頂版部材の掛け渡し方向に沿った配筋をそのまま斜め方向に延長して突出させた鉄筋と、頂版部材から斜め方向に突出させた配筋とが連結されてコンクリートにより一体化されるので、施工性が向上する。 (5) The reinforcing bars protruded from the top plate member are arranged in an oblique direction with respect to the outer surface of the standing wall portion of the pair of side wall members, and the reinforcing bars protruded from the side wall members are inclined from the top plate member. The reinforcing bars are arranged in a direction along the reinforcing bars protruding in the direction, so that the reinforcing bars along the extending direction of the top plate member are extended in the oblique direction as they are and protruded from the top plate member. Since the reinforcing bar protruding obliquely is connected and integrated with concrete, the workability is improved.
(6)側壁部材の鉄筋および頂版部材の鉄筋が、それぞれ側壁部材および頂版部材からループ状に突出させたものであることにより、側壁部材の鉄筋および頂版部材の鉄筋が、それぞれ側壁部材および頂版部材に強固に位置決めされて固定されているので、側壁部材と頂版部との接合強度がさらに向上する。 (6) Since the reinforcing bars of the side wall member and the reinforcing member of the top plate member are respectively protruded in a loop from the side wall member and the top plate member, the reinforcing bars of the side wall member and the reinforcing bar of the top plate member are respectively side wall members. Further, since the top plate member is firmly positioned and fixed, the bonding strength between the side wall member and the top plate portion is further improved.

図3に示すように、底版部4の鉄筋41は、頂版部材3の鉄筋32と平行方向に配設される。一方、本実施形態においては、鉄筋23,27は立壁部20の外面20bに対して直角方向に形成されており、スリーブ26によって底版部4の鉄筋41と接続される。なお、側壁部材2は、基礎コンクリート5上にL字状の金具50およびボルト51からなる側壁固定用治具により固定される。   As shown in FIG. 3, the reinforcing bars 41 of the bottom plate portion 4 are arranged in a direction parallel to the reinforcing bars 32 of the top plate member 3. On the other hand, in the present embodiment, the reinforcing bars 23 and 27 are formed in a direction perpendicular to the outer surface 20 b of the standing wall portion 20, and are connected to the reinforcing bar 41 of the bottom plate portion 4 by the sleeve 26. The side wall member 2 is fixed on the foundation concrete 5 by a side wall fixing jig including an L-shaped metal fitting 50 and a bolt 51.
次に、上記構成のコンクリート組立構造体1の施工方法について説明する。まず、コンクリート組立構造体1の幅に対応して左右に基礎コンクリート5を打設し、この基礎コンクリート5上に側壁部材2,2を対面配置し、金具50およびボルト51により固定する。また、基礎コンクリート5間に捨てコンクリート6を敷設し、底版部4の鉄筋41などを配筋し、現場打ちコンクリートにより底版部4を形成する。   Next, the construction method of the concrete assembly structure 1 having the above configuration will be described. First, foundation concrete 5 is placed on the left and right according to the width of the concrete assembly structure 1, and the side wall members 2, 2 are arranged facing each other on the foundation concrete 5, and fixed with metal fittings 50 and bolts 51. Further, the discarded concrete 6 is laid between the foundation concrete 5, the reinforcing bars 41 and the like of the bottom plate portion 4 are arranged, and the bottom plate portion 4 is formed by on-site concrete.
次に、頂版部材3を側壁部材2,2の上部間にそれぞれ隅角部7を空けて掛け渡し、頂版部材3の鉄筋32の突設部32aと側壁部材2,2の鉄筋23の突設部23aとを鉄筋70により連結する。そして、この隅角部7にコンクリートを打設して打設コンクリート部を形成する。   Next, the top plate member 3 is spanned between the upper portions of the side wall members 2, 2 with the corners 7 therebetween, and the protruding portions 32 a of the reinforcing bars 32 of the top plate member 3 and the reinforcing bars 23 of the side wall members 2, 2 are arranged. The projecting portion 23 a is connected to the reinforcing bar 70. And concrete is cast in this corner part 7, and a placement concrete part is formed.
このようにして構築したコンクリート組立構造体1では、側壁部材2および頂版部材3がプレキャストコンクリート製であり、施工現場においては、頂版部材3を側壁部材2,2の上部間にそれぞれ隅角部7を空けて掛け渡し、頂版部材3の鉄筋32と側壁部材2の鉄筋23とを連結し、隅角部7にコンクリートを打設すれば良いため、短時間での施工が可能となり、施工性が良い。   In the concrete assembly structure 1 constructed as described above, the side wall member 2 and the top plate member 3 are made of precast concrete. Since the portion 7 is opened and connected, the reinforcing bar 32 of the top plate member 3 and the reinforcing bar 23 of the side wall member 2 are connected, and concrete may be placed in the corner portion 7, so that construction in a short time becomes possible. Good workability.
また、頂版部材3と側壁部材2,2とがそれぞれから突出させた鉄筋32,23により連結され、コンクリートにより一体化されているため、側壁部材2と頂版部材3との接合強度が優れている。特に、こられの側壁部材2の鉄筋23および頂版部材3の鉄筋23は、それぞれ側壁部材2および頂版部材3からループ状に突出させたものであることから、それぞれ側壁部材2および頂版部材3に強固に位置決めされて固定されているので、側壁部材2と頂版部材3との接合強度がさらに向上している。   Moreover, since the top plate member 3 and the side wall members 2 and 2 are connected by the reinforcing bars 32 and 23 protruded from each other and integrated by concrete, the bonding strength between the side wall member 2 and the top plate member 3 is excellent. ing. In particular, the reinforcing bar 23 of the side wall member 2 and the reinforcing bar 23 of the top plate member 3 are projected from the side wall member 2 and the top plate member 3 in a loop shape, respectively. Since the member 3 is firmly positioned and fixed, the bonding strength between the side wall member 2 and the top plate member 3 is further improved.
また、本実施形態におけるコンクリート組立構造体1では、頂版部材3が側壁部材2の立壁部20の内面側に突出させた張り出し受け部21上に載置されるので、側壁部材2の立壁部20の上方が空いている。そのため、側壁部材2の立壁部20の配筋を上方へ延長して突出させた鉄筋23と、張り出し受け部21上に載置された頂版部材3から突出させた鉄筋32とを連結してコンクリートにより一体化することができ、側壁部材2と頂版部材3との接合強度がさらに優れている。   Further, in the concrete assembly structure 1 in the present embodiment, the top plate member 3 is placed on the overhang receiving portion 21 that protrudes to the inner surface side of the standing wall portion 20 of the side wall member 2, so that the standing wall portion of the side wall member 2 is Above 20 is vacant. Therefore, the reinforcing bar 23 which protruded by extending the reinforcement of the standing wall part 20 of the side wall member 2 and the reinforcing bar 32 protruded from the top plate member 3 placed on the overhang receiving part 21 are connected. It can be integrated with concrete, and the bonding strength between the side wall member 2 and the top plate member 3 is further excellent.
また、本実施形態におけるコンクリート組立構造体1は、側壁部材2が、それぞれ張り出し受け部21上に、頂版部材3の位置決めのために上方へ突出させた鉄筋24を有するものであり、頂版部材3が、この鉄筋24の先端部24aが挿入される挿通孔31を有するので、頂版部材3をその挿通孔31に側壁部材2の張り出し受け部21上の鉄筋24の先端部24aが挿入されるように配置することで、頂版部材3が位置決めされ、施工性が向上している。なお、挿通孔31は、鉄筋24の先端部24aが挿入可能な空隙部であれば良く、頂版部材3の端面に形成した切欠部とすることも可能である。   Moreover, the concrete assembly structure 1 in this embodiment is such that the side wall members 2 each have a reinforcing bar 24 that protrudes upward on the overhang receiving portion 21 for positioning the top plate member 3. Since the member 3 has the insertion hole 31 into which the distal end portion 24 a of the reinforcing bar 24 is inserted, the distal end portion 24 a of the reinforcing bar 24 on the overhang receiving portion 21 of the side wall member 2 is inserted into the insertion hole 31 of the top plate member 3. By arrange | positioning so that the top plate member 3 may be positioned, workability | operativity is improving. The insertion hole 31 only needs to be a gap in which the tip 24 a of the reinforcing bar 24 can be inserted, and can be a notch formed in the end surface of the top plate member 3.
また、本実施形態におけるコンクリート組立構造体1は、斜角に施工するものであるが、側壁部材2は斜角用の特殊なものではなく、頂版部材3が、掛け渡し方向に沿った側面30が側壁部材2の立壁部20の外面20bに対して75°の斜め方向に形成されているだけである。したがって、側壁部材2は通常の型枠により形成することが可能であり、頂版部材3のみを斜角に対応する型枠により形成すれば良い。この頂版部材3は、図7に示すように側面30のみが斜めに形成された平板状であるため、型枠の形成は容易である。   Moreover, although the concrete assembly structure 1 in this embodiment is constructed at an oblique angle, the side wall member 2 is not a special one for the oblique angle, and the top plate member 3 is a side surface along the spanning direction. 30 is formed in an oblique direction of 75 ° with respect to the outer surface 20 b of the standing wall portion 20 of the side wall member 2. Therefore, the side wall member 2 can be formed by a normal mold, and only the top plate member 3 may be formed by a mold corresponding to the oblique angle. Since the top plate member 3 has a flat plate shape in which only the side surface 30 is formed obliquely as shown in FIG. 7, it is easy to form a mold.
そのため、頂版部材3の側面30の角度については75°以外の角度でも容易に型枠を調整して形成することが可能であり、例えば、60°以上90°未満の範囲で任意に調整することが可能である。なお、頂版部材3の強度上の問題がなければ60°未満とすることも可能である。また、図8に示すように、頂版部材34,35のそれぞれの両側面34a,34bおよび35a,35bの角度を少しずつずらしていくことで、左右の幅の異なるコンクリート組立構造体を構築することも容易である。もちろん、側面30の角度を側壁部材2の立壁部20の外面20bに対して90°とすることも可能である。   Therefore, the angle of the side surface 30 of the top plate member 3 can be easily adjusted and formed even at an angle other than 75 °, for example, arbitrarily adjusted within a range of 60 ° or more and less than 90 °. It is possible. If there is no problem with the strength of the top plate member 3, it may be less than 60 °. Further, as shown in FIG. 8, concrete assembly structures having different left and right widths are constructed by gradually shifting the angles of both side surfaces 34a, 34b and 35a, 35b of the top plate members 34, 35. It is also easy. Of course, the angle of the side surface 30 can be 90 ° with respect to the outer surface 20 b of the standing wall portion 20 of the side wall member 2.
