Description

本発明は、建物の構築方法において、柱を鉄筋コンクリート造にして、梁を鉄骨構造にする複合構造（ＲＣＳ造）における仕口鉄骨の固定方法と仕口構造に関するものである。   The present invention relates to a method for fixing a joint steel frame and a joint structure in a composite structure (RCS structure) in which a column is reinforced concrete and a beam is a steel structure in a building construction method.

従来、柱が鉄筋コンクリート（ＲＣ）造で、梁が鉄骨（Ｓ）造の複合構造の場合、柱と仕口鉄骨の取付けにおいて、一例として、柱に仮設鉄骨を内蔵させておいて、鉄骨建方のようにして施工することができた。しかしながら、前記仮設鉄骨のコストが嵩み、更に、前記仮設鉄骨だけでは自立しないので、ブレース材等で構造的に補強する必要があって、手間が掛かりコストも嵩むものであった。   Conventionally, when the column is a reinforced concrete (RC) structure and the beam is a steel (S) composite structure, as an example when mounting the column and the jointed steel frame, the column is built with a temporary steel frame, It was possible to construct as follows. However, the cost of the temporary steel frame is increased, and further, since the temporary steel frame alone is not self-supporting, it is necessary to reinforce structurally with a brace material or the like.

そこで、図９に示すように、例えば、柱に前記仮設鉄骨を内蔵させないで、バンドプレート（高さ１７５ｍｍ程度）１ｃを仕口下に取り付けて、ベースモルタル等で仕口を支持させる場合がある。なお、関連した技術背景として、杭上に設けた基礎梁の仕口鉄骨と基礎梁端部とをコンクリートで連結する従来例が、特許文献１に記載されているように知られ
ている。 Therefore, as shown in FIG. 9, for example, the temporary steel frame may not be built in the column, and a band plate (height of about 175 mm) 1c may be attached under the joint and the joint may be supported by a base mortar or the like. . As a related technical background, a conventional example in which a jointed steel frame of a foundation beam provided on a pile and an end portion of the foundation beam are connected with concrete is known as described in Patent Document 1.

しかし、従来の複合構造における仕口鉄骨の固定方法において、ベースモルタルで仕口を支持させる方法では、仕口の設置が困難であり、床コンクリート打設時の荷重に耐えられない場合もあるので、仕口を設置後から床コンクリート打設前までの間に、梁下の梁下空間１０までコンクリートを打設して、その後に、床コンクリートを打設する場合がある。しかし、これでは、仕口鉄骨の水平方向の位置調整や上下方向の高さ調整が煩わしく、且つ、精度良く設置することが困難である。更に、床コンクリートと梁下のコンクリートとの間に、コンクリートの打継ぎ部分が発生する。本発明に係る複合構造における仕口鉄骨の固定方法と仕口構造は、このような課題を解決するために提案されたものである。   However, in the conventional method of fixing a jointed steel frame in a composite structure, the method of supporting the joint with a base mortar makes it difficult to install the joint and may not be able to withstand the load when placing floor concrete. In some cases, after placing the joint and before placing the floor concrete, concrete is placed up to the space 10 below the beam, and then the floor concrete is placed. However, in this case, the horizontal position adjustment and the vertical height adjustment of the jointed steel frame are troublesome and it is difficult to install with high accuracy. Furthermore, a jointed portion of the concrete is generated between the floor concrete and the concrete under the beam. The method for fixing a joint steel frame and the joint structure in the composite structure according to the present invention have been proposed in order to solve such problems.

本発明に係る複合構造における仕口鉄骨の固定方法の上記課題を解決して目的を達成するための要旨は、柱躯体の上に仕口鉄骨を載置して固定する方法であって、柱躯体の上部に、一端部を前記柱躯体中に埋設させ、他端部を前記柱躯体の上端面から突出させて仕口鉄骨を支持する仕口支持部材を所要数設け、前記仕口支持部材が柱躯体の上端面から突出している部分の上部に、仕口高さ調整部材を、高さ位置未調整状態でそれぞれに設け、前記柱躯体が構築された後に、前記仕口高さ調整部材の高さ位置を仕口鉄骨の取付位置に合わせて高さ調整して、前記仕口高さ調整部材を所定高さに位置固定し、仕口鉄骨の据置き用のガイドとなるガイド部材を前記柱上端面の周囲縁部に載置して位置固定し、降下してくる仕口鉄骨を前記ガイド部材でガイドさせながら、前記仕口鉄骨を前記仕口高さ調整部材の上に載置して、更に、前記仕口鉄骨に梁部材を連結して当該仕口鉄骨を位置固定することである。   The gist for achieving the object by solving the above-described problem of the method for fixing a steel frame in a composite structure according to the present invention is a method of mounting and fixing a steel frame on a column frame, At the upper part of the housing, a required number of joint support members are provided to support the joint steel with one end embedded in the pillar housing and the other end protruding from the upper end surface of the pillar housing, and the joint support member Is provided with a joint height adjusting member at an upper portion of the portion protruding from the upper end surface of the column housing in a height position unadjusted state, and after the column housing is constructed, the joint height adjusting member The height position of the joint is adjusted in accordance with the fitting position of the joint steel frame, the joint height adjustment member is fixed at a predetermined height, and a guide member serving as a guide for the stationary steel frame is installed. Placed on the peripheral edge of the upper end surface of the column and fixed in position, the lowered steel frame is lowered to the guide member While the guide, said Joint steel is placed on the Joint height adjusting member, further, is that by coupling the beam member to the Joint steel positioned fixing the Joint steel.

前記柱躯体用の柱主筋と帯筋とを配筋した後に、前記柱主筋の上部位置にある帯筋において、仕口鉄骨を支持する複数箇所に鉛直方向に沿って仕口支持部材を固定手段で固定し、前記仕口支持部材の上部に仕口高さ調整部材を仮止めし、前記柱主筋の周囲に型枠を設置し、その後、前記型枠内にコンクリートを打設し、当該コンクリートの所要強度の発現後に、前記柱躯体の上端面から突出している仕口支持部材に仮止めしてある仕口高さ調整部材の高さ位置を所定高さに位置固定した後に、前記仕口高さ調整部材と仕口支持部材とを互いに固定手段で固定することである。   Fixing means for fixing the joint support member along the vertical direction at a plurality of locations supporting the joint steel frame in the strap located at the upper position of the pillar main reinforcement after arranging the column main reinforcement and the reinforcement for the column main body The joint height adjustment member is temporarily fixed to the upper part of the joint support member, a mold is installed around the column main reinforcement, and then concrete is placed in the mold, the concrete. After the required strength is expressed, after fixing the height position of the joint height adjusting member temporarily fixed to the joint support member protruding from the upper end surface of the column housing to a predetermined height, the joint The height adjusting member and the joint support member are fixed to each other by a fixing means.

前記ガイド部材は、仕口鉄骨に設けられたバンドプレートを該仕口鉄骨の降下・設置の際にガイドすべく、予め所要の枠体形状に治具として組み立てられ、柱躯体の上方から降ろされて柱上端面の周囲縁部に載置されるとともに固定手段で位置固定されるものであることを含むものである。   The guide member is assembled in advance as a jig in a required frame shape to guide the band plate provided on the jointed steel frame when the jointed steel frame is lowered and installed, and is lowered from above the column frame. It is mounted on the peripheral edge of the upper end surface of the column and is fixed in position by a fixing means.

本発明に係る複合構造における仕口構造の要旨は、上記本発明に係る仕口鉄骨の固定方法にて前記柱躯体の上に梁用の仕口鉄骨を固定し、前記梁用の仕口鉄骨に梁鉄骨を接続し、前記仕口鉄骨の内部にコンクリートを充填させて、柱躯体と仕口鉄骨とを一体に連結させてなることである。   The gist of the joint structure in the composite structure according to the present invention is that a joint steel for a beam is fixed on the column frame by the method for fixing a joint steel according to the present invention, and the joint steel for the beam is used. A beam steel frame is connected to the steel frame, concrete is filled into the jointed steel frame, and the column frame and the jointed steel frame are integrally coupled.

本発明の複合構造における仕口鉄骨の固定方法と仕口構造によれば、仕口鉄骨の取付精度が向上するとともに、仕口鉄骨を柱上に載置する作業が、ガイド部材にガイドされて容易であり、且つ、仕口鉄骨設置作業の手間が短縮され、効率的になる。また、仕口高さ調整部材及び仕口支持部材で仕口の高さをレベル調整するので、従来のベースモルタル等を施工した場合のモルタル強度の発現を待つ手間が省けることになる。更に、仕口部分におけるコンクリートの打設回数が減って打継ぎが発生せず、コンクリート強度においても好ましい仕口構造になる、と言う数々の優れた効果を奏するものである。   According to the joint steel fixing method and joint structure in the composite structure of the present invention, the accuracy of attaching the joint steel is improved, and the work of placing the joint steel on the column is guided by the guide member. It is easy, and the labor for installing the jointed steel frame is shortened and becomes efficient. In addition, since the height of the joint is adjusted by the joint height adjusting member and the joint support member, it is possible to save the trouble of waiting for the expression of the mortar strength when the conventional base mortar is constructed. Furthermore, there are many excellent effects that the number of times of placing the concrete in the joint portion is reduced and no splicing occurs, and the joint structure is preferable in terms of concrete strength.

本発明に係る複合構造における仕口鉄骨１の固定方法は、図１に示すように、仕口高さ調整部材とガイド部材とで、前記仕口鉄骨１を位置決めして柱上端面に載置して、該仕口鉄骨１を梁部材に接続して位置固定することである。   As shown in FIG. 1, the method of fixing the joint steel frame 1 in the composite structure according to the present invention positions the joint steel frame 1 with a joint height adjusting member and a guide member and places the joint steel frame 1 on the column upper end surface. Then, the joint steel frame 1 is connected to the beam member and fixed in position.

本発明に係る複合構造における仕口鉄骨１の固定方法は、図１に示すように、柱躯体４の上に、仕口高さ調整部材としてのフランジ付きナット２および仕口鉄骨載置用のガイド部材（ガイドバー）３を設けて仕口鉄骨１を載置して固定する方法である。以下、施工手順に沿って、各部材等を説明しながら、仕口鉄骨１の固定方法を説明する。   As shown in FIG. 1, the method for fixing the joint steel frame 1 in the composite structure according to the present invention is provided on the column housing 4 with the flanged nut 2 as the joint height adjusting member and the joint steel frame mounting. In this method, a guide member (guide bar) 3 is provided and the jointed steel frame 1 is placed and fixed. Hereinafter, the fixing method of the jointed steel frame 1 will be described while explaining each member and the like along the construction procedure.

前記柱躯体４構築用の柱主筋４ａと帯筋４ｃとを配筋した後に、図２，図３に示すように、前記柱主筋４ａの上部位置で仕口鉄骨１を支持する複数箇所（図示では４箇所）に鉛直方向に沿って、仕口支持部材として、例えば、段取り筋５を、番線等の固定手段で前記帯筋４ｃに固定する。この作業は、柱躯体４用の型枠８の組立との同時施工でも良い。尚、前記仕口支持部材は、前記帯筋４ｃに固定するだけに限定されず、例えば、柱躯体４の柱上端面４ｂに植設したり、主筋等に取り付けたりして、仕口鉄骨１を支持する箇所に位置固定されるものであれば良い。   After arranging the column main reinforcement 4a and the band reinforcement 4c for constructing the column housing 4, as shown in FIGS. 2 and 3, a plurality of locations (illustrated) for supporting the joint steel frame 1 at the upper position of the column main reinforcement 4a. Then, for example, a setup bar 5 is fixed to the band bar 4c as a joint support member along the vertical direction by a fixing means such as a wire. This operation may be performed simultaneously with the assembly of the mold 8 for the column housing 4. The joint support member is not limited to being fixed to the band 4c. For example, the joint support member is planted on the column upper end surface 4b of the column housing 4 or attached to the main reinforcement or the like. What is necessary is just to be position-fixed to the location which supports.

前記段取り筋５は、一例として、適宜直径の１本のねじ鉄筋、若しくは、太径の全ネジ、その他の支持目的を達成する強度を有する部材等を使用するものである。図２に示すように、前記段取り筋５は、鉛直方向において複数の帯筋４ｃに亘るような長さで、且つ、柱上端面４ｂから突出させる長さである。   For example, the set-up bar 5 uses one screw reinforcing bar having an appropriate diameter, a large-diameter full screw, or a member having a strength that achieves another supporting purpose. As shown in FIG. 2, the set-up bars 5 have a length that extends over the plurality of band bars 4c in the vertical direction and a length that protrudes from the column upper end surface 4b.

更に、この段取り筋５の上端の位置は、仕口鉄骨１の下端面１ｄの位置よりも明らかに下位置になる位置に設定される。但し、前記フランジ付きナット２の鉛直方向に沿った位置調整に必要なネジ部の長さが、柱上端面４ｂから前記段取り筋５が突出している長さＬ１として確保されているものでなければならない。 Further, the position of the upper end of the setup bar 5 is set to a position clearly lower than the position of the lower end surface 1 d of the joint steel frame 1. However, the length of the threaded portion required alignment along the vertical direction of the flanged nut 2, as they do not have the setup muscle 5 from pillar upper end surface 4b is secured as the length L 1 that projects I must.

図２および図３に示すように、４箇所に設けた前記段取り筋５の上部に、仕口高さ調整部材の一例として、例えば、フランジ付きナット２およびナット６を、鉛直方向に沿った高さ位置の未調整状態で、それぞれ螺着して仮止めする。この仕口高さ調整部材は、前記フランジ付きナット２とナット６との組み合わせに限定されること無く、高さ位置決めを精度良く達成できるもので有れば、特に限定するものではない。   As shown in FIG. 2 and FIG. 3, for example, a flanged nut 2 and a nut 6 are provided on the upper part of the set-up bars 5 provided at four locations as an example of a joint height adjusting member. In the unadjusted state, each is screwed and temporarily fixed. The joint height adjusting member is not particularly limited as long as it can accurately achieve height positioning without being limited to the combination of the nut 2 with flange and the nut 6.

前記柱主筋４ａの周囲に柱用の型枠８を設置して、その後に、前記型枠８内にコンクリートを打設する。前記型枠８は、木製、金属製、樹脂製、コンクリート製などであり、また、型枠の断面の大きさや、上下高さを調整できるシステム型枠等でも良い。   A column mold 8 is installed around the column main reinforcement 4 a, and then concrete is placed in the mold 8. The mold 8 is made of wood, metal, resin, concrete, or the like, and may be a system mold that can adjust the cross-sectional size and the vertical height of the mold.

前記型枠８内に打設したコンクリートの所要強度が発現して柱躯体４が完成する。次に、前記柱躯体４用のコンクリートの柱上端面４ｂから突出している、前記仕口支持部材である段取り筋５に螺着し仮止めしてある、仕口高さ調整部材の一例であるフランジ付きナット２の高さ位置を、図２に示す仕口鉄骨１の下端面１ｄと一致するように、高さ調整する。   The required strength of the concrete placed in the mold 8 is developed, and the column body 4 is completed. Next, it is an example of the joint height adjusting member that is screwed and temporarily fixed to the setup bar 5 that is the joint support member, protruding from the column upper end surface 4b of the concrete for the pillar frame 4. The height of the flanged nut 2 is adjusted so as to coincide with the lower end surface 1d of the jointed steel frame 1 shown in FIG.

図４（Ａ），（Ｂ）に示すように、例えば、前記フランジ付きナット２を回転させて適宜に上下に移動させ、フランジ２ａの上端面の位置が所定の高さになったら、回転を停止させる。   As shown in FIGS. 4A and 4B, for example, the flanged nut 2 is rotated and appropriately moved up and down, and when the position of the upper end surface of the flange 2a reaches a predetermined height, the rotation is performed. Stop.

前記フランジ付きナット２を直ちに固定手段である、溶接による固定方法、接着剤による固定方法等で上下方向の位置を固定する。なお、前記固定手段で前記フランジ付きナット２を固定するまでに、フランジ付きナット２が上下移動しないように、位置固定する必要があれば、前記フランジ付きナット２の下位置に予め、配置させていたナット（若しくはロックナット等も含む）６を回転させてねじり上げて、前記フランジ付きナット２に当該ナット６を当接させて本締めすることで、当該フランジ付きナット２が上下方向に移動しないように位置決めすることができる。こうして、前記フランジ付きナット２のフランジ２ａ上端面に、仕口鉄骨１が載置されることになる。   The flanged nut 2 is immediately fixed in the vertical direction by a fixing method such as welding or an adhesive. If it is necessary to fix the position of the flanged nut 2 so that the flanged nut 2 does not move up and down before the flanged nut 2 is fixed by the fixing means, the flanged nut 2 is placed in advance under the flanged nut 2. The nut 6 (including a lock nut or the like) is rotated and twisted up so that the nut 6 is brought into contact with the flanged nut 2 and finally tightened, so that the flanged nut 2 does not move in the vertical direction. Can be positioned as follows. Thus, the closed steel frame 1 is placed on the upper end surface of the flange 2a of the nut 2 with flange.

更に、図１と図５（Ａ），（Ｂ）とに示すように、仕口鉄骨１の下部のバンドプレート１ｃを柱上端面４ｂに設置する際の、当該バンドプレート１ｃの据え置き用のガイドとなるガイド部材であるガイドバー３を、前記柱上端面４ｂの周囲縁部に載置する。   Further, as shown in FIG. 1 and FIGS. 5A and 5B, a guide for placing the band plate 1c when the band plate 1c below the jointed steel frame 1 is installed on the column upper end surface 4b. The guide bar 3 which is a guide member is placed on the peripheral edge of the column upper end surface 4b.

前記ガイド部材の一例としては、ガイドバー３は、図５（Ａ）に示すように、例えば、その１枚の大きさが、高さＨが略１００ｍｍ程度、長さＬ２が柱躯体４の１辺長さと略同じ長さ、板厚ｔが適宜厚さの金属板である。なお、これに限らず、棒状体のバーや、長さの短い不連続な棒体を並べて構成しても良く、作業者が前記仕口鉄骨１のバンドプレート１ｃを誘導し、載置する際のガイドとなるのに適した部材であれば、形状、大きさ、材質を特に限定するものではない。 As an example of the guide member, as shown in FIG. 5A, the guide bar 3 has, for example, a size of one of the guide bars 3 having a height H of about 100 mm and a length L 2 of the column housing 4. A metal plate having a length that is substantially the same as the length of one side and a plate thickness t appropriately. However, the present invention is not limited to this, and a bar-shaped bar or a discontinuous bar having a short length may be arranged side by side. When the operator guides and places the band plate 1c of the joint steel frame 1, The shape, size, and material are not particularly limited as long as the material is suitable for the guide.

図５（Ａ）に示すように、４枚の前記ガイドバー３を矩形状に組み付け、その端部同士を溶接してガイド枠３ｂを形成する。更に、図５（Ａ）、図６に示すように、前記ガイド枠３ｂの他に、下層階では強度的に必要であれば、斜材（ブレース）３ａを前記４枚のガイドバー３のうち隣接するガイドバー３，３にそれぞれ架設する。該斜材３ａの端部とガイドバー３内壁面とを溶接手段で溶接し、ガイドバー３内側に斜材３ａを固定する。こうして強度的な補強を施しても良い。上層階では、柱も細くなり強度的にも補強が不要なので、前記斜材３ａは不要とする。   As shown in FIG. 5A, the four guide bars 3 are assembled in a rectangular shape, and the ends thereof are welded to form a guide frame 3b. Further, as shown in FIGS. 5A and 6, in addition to the guide frame 3b, if it is necessary for strength on the lower floor, a diagonal member (brace) 3a is placed on the four guide bars 3. It is installed on the adjacent guide bars 3 and 3 respectively. The end of the diagonal member 3a and the inner wall surface of the guide bar 3 are welded by welding means, and the diagonal member 3a is fixed inside the guide bar 3. Thus, strength reinforcement may be applied. On the upper floor, the column is thin and reinforcement is not required in terms of strength, so the diagonal material 3a is not required.

このガイド枠３ｂの全体の大きさは、仕口鉄骨１の塞ぎ板１ａの下部に設けてあるバンドプレート１ｃ（図９参照）の矩形状の大きさよりも、一回り大きくして形成されている。なお、他の実施例として、図示していないが、前記ガイド枠３を前記バンドプレート１ｃよりも一回り小さくして、当該バンドプレート１ｃを内側からガイドするようにしてもよい。   The entire size of the guide frame 3b is formed to be slightly larger than the rectangular size of the band plate 1c (see FIG. 9) provided at the lower portion of the closing plate 1a of the jointed steel frame 1. . As another embodiment, although not shown, the guide frame 3 may be slightly smaller than the band plate 1c to guide the band plate 1c from the inside.

前記ガイド枠３ｂは、図５（Ｂ）に示すように、柱上端面４ｂの墨に沿って、ガイド治具として柱躯体の上方から載置されるものである。よって、前記斜材３ａは、柱主筋４ａ等と衝突しないように、配設されている。   As shown in FIG. 5B, the guide frame 3b is placed from above the column housing as a guide jig along the black ink on the column upper end surface 4b. Therefore, the diagonal member 3a is disposed so as not to collide with the column main reinforcement 4a and the like.

前記ガイドバー３は、前記柱躯体４の柱上端面４ｂに設けた墨に合わせるようにして、組み立てられるものである。よって、前記ガイド枠３ｂを矩形状の枠に形成して、これをガイド用の治具としても良いが、これに限らず他の実施例として、柱躯体４の上端面４ｂにおいて、墨に沿わせて前記ガイドバー３を載置する。そして、固定用補助筋７で前記ガイドバー３および段取り筋５を溶接手段で溶接して固定する。これを柱上端面４ｂの４箇所の墨に対してそれぞれ行っていく。このように、治具としての前記ガイド枠３ｂを形成しないで、ガイドバー３を適宜手段で配設することもできる。   The guide bar 3 is assembled so as to match the black provided on the column upper end surface 4 b of the column housing 4. Therefore, the guide frame 3b may be formed in a rectangular frame and used as a guide jig. However, the guide frame 3b is not limited to this, and as another example, the upper end surface 4b of the column housing 4 is in line with the ink. Then, the guide bar 3 is placed. Then, the guide bar 3 and the set-up bar 5 are welded and fixed by welding means with the fixing auxiliary bars 7. This is performed for each of the four ink spots on the column upper end surface 4b. As described above, the guide bar 3 can be disposed by appropriate means without forming the guide frame 3b as a jig.

前記ガイドバー３を、固定用補助筋７を介して前記段取り筋５に溶接止めして位置固定した後は、図７、図８に示すように、前記柱躯体４の柱上端面４ｂにおいて、前記ガイドバー３にバンドプレート１ｃをガイドさせながら、クレーン等で吊持して搬入した仕口鉄骨１を４箇所のフランジ付きナット２の上に載置する。前記バンドプレート１ｃは、その下端面の位置が、柱躯体４の柱上端面４ｂに当たることのないように、上下方向の高さ寸法が設定されている。   After the guide bar 3 is welded and fixed to the set-up bar 5 via the fixing auxiliary bar 7, as shown in FIGS. 7 and 8, on the column upper end surface 4b of the column frame 4, While the band plate 1c is guided by the guide bar 3, the joint steel frame 1 suspended and carried by a crane or the like is placed on four flanged nuts 2. The band plate 1c has a height dimension in the vertical direction so that the position of the lower end surface thereof does not hit the column upper end surface 4b of the column housing 4.

前記仕口鉄骨１のバンドプレート１ｃと、ガイドバー３との水平方向の間には、コンクリート天端精度によっては隙間が生じることがあり、その隙間からコンクリート流出のおそれがある場合には、その隙間を塞ぐようにテープ等を貼着させたり、前記隙間にモルタルなどを充填したりする等して封止する。更に、前記仕口鉄骨１に梁部材（図示せず）をボルト・ナットで連結して、当該仕口鉄骨１を位置固定する。これを所定の工区内で行って、多数の仕口鉄骨１を互いに梁部材を介して連結する。   Between the horizontal direction of the band plate 1c of the jointed steel frame 1 and the guide bar 3, there may be a gap depending on the accuracy of the top of the concrete. Sealing is performed by attaching a tape or the like so as to close the gap, or filling the gap with mortar or the like. Further, a beam member (not shown) is connected to the jointed steel frame 1 with bolts and nuts, and the jointed steel frame 1 is fixed in position. This is performed in a predetermined work area, and a large number of jointed steel frames 1 are connected to each other via beam members.

前記梁部材の上に床デッキ等を敷設して、更に、床配筋をした後に、床コンクリートの打設よりも先に、若しくは同時に、前記仕口鉄骨１における梁下のバンドプレート１ｃとガイドバー３とで囲まれた梁下空間１０（図７参照）も含めて、前記仕口鉄骨１の塞ぎ板１ａの内部にコンクリートを打設して充填する。こうして、工期短縮とコンクリート打継ぎ部分の解消となる。   After laying a floor deck or the like on the beam member and further arranging the floor, prior to or simultaneously with placing the floor concrete, the band plate 1c below the beam in the joint steel frame 1 and the guide Concrete is cast and filled inside the closing plate 1a of the jointed steel frame 1 including the space 10 below the beam surrounded by the bar 3 (see FIG. 7). In this way, the construction period is shortened and the concrete joint portion is eliminated.

なお、前記ガイドバー３によるガイド枠３ｂは、全体が金属製であり、解体・撤去作業の無駄を省くために、そのままにされる。当該ガイドバー３は、金属製の他、木製でもプラスチック製でも良いが、後の処理も考慮すると、前記仕口鉄骨１による仕口構造の完成後に、そのまま放置することができる金属製が好ましいものである。   The guide frame 3b by the guide bar 3 is entirely made of metal, and is left as it is in order to eliminate waste of dismantling / removal work. The guide bar 3 may be made of metal or wooden or plastic, but considering the subsequent processing, the guide bar 3 is preferably made of metal that can be left as it is after the joint structure of the joint steel frame 1 is completed. It is.

前記仕口鉄骨１へのコンクリート打設とともに、若しくは、前記コンクリート打設後に、床デッキ上に床コンクリートを打設するものである。こうして、仕口鉄骨１のコンクリートと床コンクリートとが一体になるものである。   The floor concrete is placed on the floor deck together with the concrete placement on the jointed steel frame 1 or after the concrete placement. In this way, the concrete of the jointed steel frame 1 and the floor concrete are integrated.

本発明に係る複合構造における仕口鉄骨の固定方法とその仕口構造は、複合構造の倉庫や体育館等の広い空間を有する建物に適用されるものである。   The method of fixing a joint steel frame and its joint structure in a composite structure according to the present invention is applied to a building having a wide space such as a warehouse or a gymnasium having a composite structure.
