Description
本発明は、梁にデッキプレートを支持するためデッキプレート用支持部材と、これを用いたデッキプレート支持構造及びその支持方法に関するものである。 The present invention relates to a deck plate support member for supporting a deck plate on a beam, a deck plate support structure using the support member, and a method for supporting the deck plate.
従来、床スラブを構築する際に、デッキプレートが用いられる場合がある。デッキプレートは、型枠として機能し、コンクリートと一体化する。 Conventionally, deck plates may be used when constructing floor slabs. The deck plate functions as a formwork and integrates with concrete.
このようなデッキプレートを梁に設置する際には、所定間隔で配置された梁の上にデッキプレートをかけ渡して配置する。しかし、梁同士がスプライスプレートなどによって接続される部位においては、スプライスプレートによって梁の上部に段差が生じ、デッキプレートの設置の妨げとなる。 When such a deck plate is installed on a beam, the deck plate is placed over the beams arranged at predetermined intervals. However, in a portion where the beams are connected to each other by a splice plate or the like, the splice plate causes a step on the upper part of the beam, which hinders the installation of the deck plate.
このような梁の接合部においてデッキプレートを設置する方法として、梁同士の接合部に、スプライスプレートを固定するボルト等を避ける孔が形成され、両端部に支持部と水平受け部とが形成された受け金具を配置し、水平受け部にデッキプレートを設置する方法がある（特許文献１）。 As a method of installing the deck plate at the joint portion of such a beam, a hole for avoiding a bolt or the like for fixing the splice plate is formed at the joint portion between the beams, and a support portion and a horizontal receiving portion are formed at both ends. There is a method of arranging the receiving metal fittings and installing the deck plate on the horizontal receiving portion (Patent Document 1).
しかし、特許文献１のように、特殊な受け金具を用いたのでは、梁のサイズごとに金具を準備する必要がある。また、金具が大型であり、コスト増ともなる。これに対し、より簡易な方法として、梁のフランジ側面に板部材を溶接し、この板部材上にデッキプレートを設置する方法がある。 However, if a special receiving metal fitting is used as in Patent Document 1, it is necessary to prepare a metal fitting for each beam size. In addition, the metal fittings are large, which increases the cost. On the other hand, as a simpler method, there is a method in which a plate member is welded to the side surface of the flange of the beam and a deck plate is installed on the plate member.
図９は、板状のデッキプレート用支持部材１０７を用いたデッキプレート１００の支持構造である。梁１０１は、一対のフランジ部１０５がウェブで接合されたＨ形鋼である。前述したように、梁１０１同士がスプライスプレート１０３によって接合されている。このため、梁１０１のフランジ部１０５の上面に凹凸が生じ、デッキプレート１００を直接設置することができない。 FIG. 9 shows a support structure of the deck plate 100 using the plate-shaped support member 107 for the deck plate. The beam 101 is an H-section steel in which a pair of flange portions 105 are joined by a web. As described above, the beams 101 are joined to each other by the splice plate 103. Therefore, the upper surface of the flange portion 105 of the beam 101 is uneven, and the deck plate 100 cannot be directly installed.
このため、梁１０１の上方のフランジ部１０５の側端面にデッキプレート用支持部材１０７が接合される。このように、デッキプレート用支持部材１０７をフランジ部１０５の側方に張り出させることで、デッキプレート１００をデッキプレート用支持部材１０７上に設置することができる。 Therefore, the deck plate support member 107 is joined to the side end surface of the flange portion 105 above the beam 101. By projecting the deck plate support member 107 to the side of the flange portion 105 in this way, the deck plate 100 can be installed on the deck plate support member 107.
図１０（ａ）は、デッキプレート用支持部材１０７をフランジ部１０５の側端面に溶接する方法の一例を示す図である。デッキプレート用支持部材１０７の端部には、溶接用の開先部１１１が形成される。フランジ部１０５の側端面とデッキプレート用支持部材１０７との間に隙間を開けて、デッキプレート用支持部材１０７とフランジ部１０５は、互いの上面の位置を合わせて配置され、裏面側に裏当金１１３を配置した状態で溶接が行われる。 FIG. 10A is a diagram showing an example of a method of welding the deck plate support member 107 to the side end surface of the flange portion 105. A groove 111 for welding is formed at the end of the deck plate support member 107. With a gap between the side end surface of the flange portion 105 and the deck plate support member 107, the deck plate support member 107 and the flange portion 105 are arranged so that their upper surfaces are aligned with each other, and the back surface is backed. Welding is performed with the gold 113 placed.
しかし、この方法では、デッキプレート用支持部材１０７の上面に溶接部１０９が盛り上がるため、デッキプレート１００との干渉を避けるため、溶接後、溶接部１０９の上面を研磨して平らにする必要がある。また、裏当金１１３を必要とするため、作業性が悪い。 However, in this method, since the welded portion 109 rises on the upper surface of the support member 107 for the deck plate, it is necessary to polish and flatten the upper surface of the welded portion 109 after welding in order to avoid interference with the deck plate 100. .. In addition, workability is poor because a backing money 113 is required.
これに対し、図１０（ｂ）に示すように、開先部１１１を大きくとり、デッキプレート用支持部材１０７の側端面をフランジ部１０５の側端面に接触させることで、裏当金１１３は不要となる。しかし、このようにすると、溶接部１０９が小さくなるため、接合強度が低下する。また、この場合でも、溶接後に溶接部１０９の上部を研磨する必要があるため、作業性が悪い。 On the other hand, as shown in FIG. 10B, the groove portion 111 is made large and the side end surface of the deck plate support member 107 is brought into contact with the side end surface of the flange portion 105, so that the backing metal 113 is unnecessary. It becomes. However, in this way, the welded portion 109 becomes smaller, so that the joint strength decreases. Further, even in this case, since it is necessary to polish the upper part of the welded portion 109 after welding, the workability is poor.
また、図１０（ｃ）に示すように、デッキプレート用支持部材１０７とフランジ部１０５の上面を合わせずに、溶接を行うと、溶接代が十分でなく、接合強度を確保することが困難である。また、段差を形成すると、隣り合う他のデッキプレートとの間で高さが変わるため望ましくない。 Further, as shown in FIG. 10C, if welding is performed without aligning the upper surfaces of the deck plate support member 107 and the flange portion 105, the welding allowance is insufficient and it is difficult to secure the joint strength. be. Further, forming a step is not desirable because the height changes between the deck plates and the adjacent deck plates.
一方、図１０（ｄ）に示すように、デッキプレート用支持部材１０７とフランジ部１０５の上面の位置を合わせて配置して、下面側を溶接すると、デッキプレート用支持部材１０７とフランジ部１０５の上面は平坦となるが、デッキプレート用支持部材１０７への上方からの力に対して溶接強度を十分に確保することが困難である。 On the other hand, as shown in FIG. 10D, when the deck plate support member 107 and the upper surface of the flange portion 105 are aligned and the lower surface side is welded, the deck plate support member 107 and the flange portion 105 are formed. Although the upper surface is flat, it is difficult to secure sufficient welding strength against a force from above on the deck plate support member 107.
本発明は、このような問題に鑑みてなされたもので、簡易な構造で、容易に固定することが可能なデッキプレート用支持部材、これを用いたデッキプレート支持構造及び支持方法を提供することを目的とする。 The present invention has been made in view of such a problem, and provides a deck plate support member that can be easily fixed with a simple structure, and a deck plate support structure and support method using the same.

前述した目的を達成するため、第１の発明は、梁に固定され、デッキプレートを支持することが可能な支持部材であって、板状の支持部材の一方の端部側に形成されるデッキプレートの支持部と、前記支持部とは逆の端部側に形成される、梁への突き当て部と、前記突き当て部に併設するように、前記突き当て部に対して板の下面方向に向けて形成される溶接受け部と、を具備することを特徴とするデッキプレート用支持部材である。 In order to achieve the above-mentioned object, the first invention is a support member fixed to a beam and capable of supporting a deck plate, and a deck formed on one end side of a plate-shaped support member. The support portion of the plate, the abutting portion to the beam formed on the end side opposite to the supporting portion, and the lower surface direction of the plate with respect to the abutting portion so as to be attached to the abutting portion. It is a support member for a deck plate, which comprises a welded receiving portion formed toward the surface of the deck plate.
前記溶接受け部は、前記突き当て部に対して板の下面方向に向けて斜めに形成されることを特徴とする請求項１記載のデッキプレート用支持部材。 The support member for a deck plate according to claim 1, wherein the weld receiving portion is formed obliquely toward the lower surface direction of the plate with respect to the abutting portion.

第１の発明によれば、突き当て部に併設するように、突き当て部に対して板の下面方向に向けて形成される溶接受け部が形成されるため、突き当て部をフランジ部の側端面に接触させた際に、溶接受け部をフランジ部の下方に位置させることができる。このため、溶接時に裏当金が不要であり、また、フランジ部の厚み分を溶接可能であるため、十分な溶接代を確保することができる。このため高い接合強度を得ることができる。 According to the first invention, since the weld receiving portion formed toward the lower surface direction of the plate is formed with respect to the abutting portion so as to be attached to the abutting portion, the abutting portion is placed on the side of the flange portion. The weld receiving portion can be positioned below the flange portion when it comes into contact with the end face. Therefore, a backing metal is not required at the time of welding, and the thickness of the flange portion can be welded, so that a sufficient welding allowance can be secured. Therefore, high bonding strength can be obtained.
この際、溶接受け部が斜めに形成されれば、形状が簡易であり、製造も容易である。 At this time, if the weld receiving portion is formed diagonally, the shape is simple and the manufacturing is easy.
また、溶接受け部の上面に、溶接範囲を示す溶接マークを形成することで、溶接部が上方にはみ出すことを抑制するとともに、確実に必要な溶接代を確保することができる。 Further, by forming a welding mark indicating the welding range on the upper surface of the welding receiving portion, it is possible to prevent the welded portion from protruding upward and to surely secure the necessary welding allowance.
また、平面視において、突き当て部の先端から、溶接受け部を突出させることで、より確実に溶接部を受けることができる。例えば、溶接受け部とフランジ部との間に多少の隙間が生じても、溶融金属が下方に流れてしまうことを抑制することができる。 Further, in a plan view, by projecting the weld receiving portion from the tip of the abutting portion, the welded portion can be received more reliably. For example, even if there is a slight gap between the weld receiving portion and the flange portion, it is possible to prevent the molten metal from flowing downward.
また、突き当て部が、互いに離間して複数個所に配置されれば、デッキプレート用支持部材をフランジ部に対して確実にまっすぐに配置することができ、デッキプレート用支持部材の配置が容易である。 Further, if the abutting portions are arranged at a plurality of locations separated from each other, the deck plate support members can be reliably arranged straight with respect to the flange portions, and the deck plate support members can be easily arranged. be.
第２の発明は、第１の発明にかかるデッキプレート用支持部材を用いたデッキプレート支持構造であって、前記突き当て部が梁のフランジ部の側端面に当接し、前記溶接受け部が前記フランジ部の下方に張り出すように前記デッキプレート用支持部材が配置され、前記溶接受け部と前記フランジ部とが溶接され、前記支持部の上にデッキプレートが設置されることを特徴とするデッキプレート支持構造である。 The second invention is a deck plate support structure using the deck plate support member according to the first invention, in which the abutting portion abuts on the side end surface of the flange portion of the beam, and the weld receiving portion is the said. The deck is characterized in that the support member for the deck plate is arranged so as to project below the flange portion, the weld receiving portion and the flange portion are welded, and the deck plate is installed on the support portion. It is a plate support structure.
第２の発明によれば、梁同士の接合部のように、フランジ部の上面に凹凸があるような場合でも、確実にデッキプレートを支持することができる。 According to the second invention, the deck plate can be reliably supported even when the upper surface of the flange portion has irregularities such as a joint portion between beams.
第３の発明は、第１の発明にかかるデッキプレート用支持部材を用いたデッキプレート支持方法であって、前記突き当て部を梁のフランジ部の側端面に当接させるとともに、前記溶接受け部が前記フランジ部の下方に張り出すように前記デッキプレート用支持部材を配置する工程と、前記溶接受け部と前記フランジ部とを溶接する工程と、前記支持部の上にデッキプレートを設置する工程と、を具備することを特徴とするデッキプレート支持方法である。 A third invention is a deck plate support method using a deck plate support member according to the first invention, wherein the abutting portion is brought into contact with a side end surface of a flange portion of a beam, and the weld receiving portion is provided. A step of arranging the support member for the deck plate so as to project below the flange portion, a step of welding the weld receiving portion and the flange portion, and a step of installing the deck plate on the support portion. It is a deck plate support method characterized by comprising.
第３の発明によれば、梁同士の接合部のように、フランジ部の上面に凹凸があるような場合でも、容易にデッキプレート用支持部材を設置することが可能であり、確実にデッキプレート支持構造を得ることができる。 According to the third invention, it is possible to easily install the support member for the deck plate even when the upper surface of the flange portion has irregularities such as a joint portion between beams, and the deck plate can be reliably installed. A support structure can be obtained.
本発明によれば、簡易な構造で、容易に固定することが可能なデッキプレート用支持部材、これを用いたデッキプレート支持構造及び支持方法を提供することができる。 According to the present invention, it is possible to provide a deck plate support member that can be easily fixed with a simple structure, a deck plate support structure using the support member, and a support method.
以下、本発明の実施の形態にかかるデッキプレート用支持部材１について説明する。図１は、デッキプレート用支持部材１を示す斜視図である。デッキプレート用支持部材１は、梁に固定されて使用され、デッキプレートを支持することが可能な支持部材である。 Hereinafter, the deck plate support member 1 according to the embodiment of the present invention will be described. FIG. 1 is a perspective view showing a deck plate support member 1. The deck plate support member 1 is a support member that is fixed to a beam and can be used to support the deck plate.
デッキプレート用支持部材１は、全体として略板状であり、板状の部材の一方の端部側にデッキプレート支持部３が形成される。デッキプレート支持部３は上面が平坦である。デッキプレート支持部３とは逆の端部側には、突き当て部５が形成される。突き当て部５は、梁へ突き当てられる部位である。突き当て部５は、互いに離間して複数個所に配置される。図示した例では、デッキプレート用支持部材１の両端部近傍の２カ所に配置される。デッキプレート支持部３と突き当て部５は、略同一面に形成される。 The deck plate support member 1 has a substantially plate shape as a whole, and the deck plate support portion 3 is formed on one end side of the plate-shaped member. The upper surface of the deck plate support portion 3 is flat. An abutting portion 5 is formed on the end side opposite to the deck plate supporting portion 3. The abutting portion 5 is a portion that is abutted against the beam. The abutting portions 5 are arranged at a plurality of locations separated from each other. In the illustrated example, the deck plate support members 1 are arranged at two locations near both ends. The deck plate support portion 3 and the abutting portion 5 are formed on substantially the same surface.
一対の突き当て部５の間には、溶接受け部７が配置される。溶接受け部７は、突き当て部５に併設するように、突き当て部５及びデッキプレート支持部３に対して板の下面方向に向けて、略まっすぐに斜めに形成される。なお、突き当て部５の長さよりも、溶接受け部７の長さは長く、平面視において、突き当て部５の先端から、溶接受け部７が突出する。なお、溶接受け部の上面には、溶接範囲を示す溶接マーク９が形成される。溶接マーク９は、例えばケガキ線等で形成される。 A weld receiving portion 7 is arranged between the pair of abutting portions 5. The weld receiving portion 7 is formed substantially straight and obliquely with respect to the abutting portion 5 and the deck plate supporting portion 3 toward the lower surface of the plate so as to be attached to the abutting portion 5. The length of the weld receiving portion 7 is longer than the length of the abutting portion 5, and the welding receiving portion 7 projects from the tip of the abutting portion 5 in a plan view. A welding mark 9 indicating a welding range is formed on the upper surface of the welding receiving portion. The welding mark 9 is formed by, for example, a marking line or the like.
なお、デッキプレート用支持部材１は、板状の素材から、溶接受け部を折り曲げて形成してもよく、鋳造や鍛造などで形成してもよい。 The deck plate support member 1 may be formed by bending a weld receiving portion from a plate-shaped material, or may be formed by casting or forging.
次に、デッキプレート用支持部材１の使用方法について説明する。図２は、デッキプレート用支持部材１を梁１１に固定した状態を示す平面図、図３（ａ）は、図２のＡ−Ａ線断面図、図３（ｂ）は、図２のＢ−Ｂ線断面図である。なお、図２、図３においては、簡単のため、スプライスプレート等の図示を省略する。 Next, a method of using the deck plate support member 1 will be described. FIG. 2 is a plan view showing a state in which the deck plate support member 1 is fixed to the beam 11, FIG. 3A is a cross-sectional view taken along the line AA of FIG. 2, and FIG. 3B is B of FIG. -B line sectional view. In addition, in FIG. 2 and FIG. 3, the illustration of the splice plate and the like is omitted for the sake of simplicity.
前述したように、梁１１はフランジ部１３を有するＨ形鋼である。デッキプレート用支持部材１のデッキプレート支持部３の上面とフランジ部１３の上面とが略同一面となるようにした状態で、突き当て部５の端面をフランジ部１３の側端面に接触させる。 As described above, the beam 11 is an H-shaped steel having a flange portion 13. The end surface of the abutting portion 5 is brought into contact with the side end surface of the flange portion 13 in a state where the upper surface of the deck plate support portion 3 of the deck plate support member 1 and the upper surface of the flange portion 13 are substantially the same surface.
この際、平面視において、突き当て部５の先端から、溶接受け部７が突出するため、溶接受け部７は、フランジ部１３の下方に向けて突出する。すなわち、溶接受け部７は、フランジ部１３の側端面（下縁部除く）とは面接触しない。 At this time, in a plan view, the weld receiving portion 7 protrudes from the tip of the abutting portion 5, so that the weld receiving portion 7 protrudes downward of the flange portion 13. That is, the weld receiving portion 7 does not come into surface contact with the side end surface (excluding the lower edge portion) of the flange portion 13.
この状態で、フランジ部１３の側端面と溶接受け部７の上面とが溶接部１５によって溶接される。以上により、デッキプレート用支持部材１が梁１１に固定される。 In this state, the side end surface of the flange portion 13 and the upper surface of the weld receiving portion 7 are welded by the welded portion 15. As described above, the deck plate support member 1 is fixed to the beam 11.
なお、溶接受け部７をフランジ部１３の下方に突出させずに、溶接受け部７の長さを平面視において突き当て部５と同等としてもよい。このようにしても、溶接受け部７とフランジ部１３との溶接を行うことができる。なお、図示した例では、溶接受け部７の上面とフランジ部１３の下縁部とが接触するが、多少の隙間が形成されてもよい。溶接受け部７がフランジ部１３の下方に突出しているため、多少の隙間が生じても、溶接時に溶融金属が下部に流れ落ちることが抑制される。 The length of the weld receiving portion 7 may be the same as that of the abutting portion 5 in a plan view without projecting the weld receiving portion 7 below the flange portion 13. Even in this way, the welding receiving portion 7 and the flange portion 13 can be welded. In the illustrated example, the upper surface of the weld receiving portion 7 and the lower edge portion of the flange portion 13 come into contact with each other, but a slight gap may be formed. Since the weld receiving portion 7 projects below the flange portion 13, even if a slight gap is generated, the molten metal is prevented from flowing down to the lower portion during welding.
ここで、溶接を行う際に、溶接受け部７の上面の溶接マーク９を目安にすることで、溶接量のばらつきを抑え、必要な溶接強度を確保することができる。なお、溶接受け部７の両端部（図２の左右方向端部）には、突き当て部５との間に隙間（図３（ａ）の溶接受け部７と突き当て部５との間の略三角形の隙間）が形成される。このため、溶接部１５は、溶接受け部７の全幅に形成しなくてもよく、両端部に隙間を開けてもよい。この場合にも、幅方向の溶接範囲を示す溶接マーク９を溶接受け部７上に形成してもよい。 Here, by using the welding mark 9 on the upper surface of the welding receiving portion 7 as a guide when performing welding, it is possible to suppress variations in the welding amount and secure the required welding strength. It should be noted that there is a gap between both ends of the weld receiving portion 7 (ends in the left-right direction in FIG. 2) and the abutting portion 5 (between the welding receiving portion 7 and the abutting portion 5 in FIG. 3A). Approximately triangular gaps) are formed. Therefore, the welded portion 15 does not have to be formed over the entire width of the weld receiving portion 7, and gaps may be provided at both ends. In this case as well, a welding mark 9 indicating a welding range in the width direction may be formed on the welding receiving portion 7.
次に、デッキプレート用支持部材１を用いたデッキプレート支持方法について説明する。図４は、デッキプレート２１を梁１１にかけ渡した状態を示す図である。デッキプレート２１は、板状の鋼製部材であり、デッキプレート２１の長手方向に沿って、主鉄筋が配置されて固定される。なお、図示した例では、所定の角度でラチス筋が接合され、鉄筋トラスが構成される。図示したように、梁１１（フランジ部１３）の上面が平坦である部位には、そのままデッキプレート２１をフランジ部１３上に配置すればよい。 Next, a deck plate support method using the deck plate support member 1 will be described. FIG. 4 is a diagram showing a state in which the deck plate 21 is stretched over the beam 11. The deck plate 21 is a plate-shaped steel member, and main reinforcing bars are arranged and fixed along the longitudinal direction of the deck plate 21. In the illustrated example, the lattice trusses are joined at a predetermined angle to form a reinforcing bar truss. As shown in the drawing, the deck plate 21 may be arranged on the flange portion 13 as it is in the portion where the upper surface of the beam 11 (flange portion 13) is flat.
図５はこのようにしてデッキプレート２１を梁１１上に設置する工程を示す図である。デッキプレート２１を設置する部位にスプライスプレート２３がある部位には、予め、デッキプレート用支持部材１を接合しておく。より詳細には、突き当て部５を梁１１のフランジ部１３の側端面に当接させるとともに、溶接受け部７がフランジ部１３の下方に張り出すようにデッキプレート用支持部材１を配置し、溶接受け部７とフランジ部１３とを溶接することで、デッキプレート用支持部材１を梁１１に接合する。 FIG. 5 is a diagram showing a process of installing the deck plate 21 on the beam 11 in this way. The deck plate support member 1 is joined in advance to the portion where the splice plate 23 is located at the portion where the deck plate 21 is installed. More specifically, the abutment portion 5 is brought into contact with the side end surface of the flange portion 13 of the beam 11, and the deck plate support member 1 is arranged so that the weld receiving portion 7 projects below the flange portion 13. By welding the weld receiving portion 7 and the flange portion 13, the deck plate support member 1 is joined to the beam 11.
図６は、この状態で、デッキプレート支持部３の上にデッキプレート２１を設置することで得られるデッキプレート支持構造２０を示す図である。この状態から、デッキプレート２１上にコンクリートを打設することで、鉄筋構造体である床スラブを得ることができる。 FIG. 6 is a diagram showing a deck plate support structure 20 obtained by installing the deck plate 21 on the deck plate support portion 3 in this state. From this state, a floor slab, which is a reinforced structure, can be obtained by placing concrete on the deck plate 21.
本実施の形態によれば、デッキプレート用支持部材１を用いることで、フランジ部１３の厚み分を全て溶接部に使用することができる。このため、溶接部１５が、デッキプレート支持部３及びフランジ部１３の上面からはみ出さないように形成されても、十分な溶接強度を得ることができる。このため、溶接部１５とデッキプレート２１との干渉を避けるために、溶接部１５の上面を研磨する必要がない。 According to the present embodiment, by using the deck plate support member 1, the entire thickness of the flange portion 13 can be used for the welded portion. Therefore, even if the welded portion 15 is formed so as not to protrude from the upper surfaces of the deck plate support portion 3 and the flange portion 13, sufficient welding strength can be obtained. Therefore, it is not necessary to polish the upper surface of the welded portion 15 in order to avoid interference between the welded portion 15 and the deck plate 21.
また、フランジ部１３の厚みを全て溶接に使用しても、突き当て部５によって確実に位置合わせをすることができる。また、溶接受け部７によって、裏当金や開先加工も不要となり、溶接作業も容易である。 Further, even if the entire thickness of the flange portion 13 is used for welding, the abutting portion 5 can be used for reliable alignment. Further, the welding receiving portion 7 eliminates the need for a backing metal and groove processing, and the welding work is easy.
また、溶接マーク９が形成されるため、溶接代を容易に把握することができ、溶接ばらつきや溶接部１５の上方へのはみ出しを抑制するとともに、確実に所望の溶接強度を確保することができる。 Further, since the welding mark 9 is formed, the welding allowance can be easily grasped, the welding variation and the protrusion of the welded portion 15 upward can be suppressed, and the desired welding strength can be surely secured. ..
なお、前述の実施形態では、突き当て部５が２カ所である例を示したが、これには限られない。例えば、図７に示すデッキプレート用支持部材１ａのように、突き当て部５を一カ所としてもよい。この場合にも、突き当て部５以外の部位を溶接受け部７とすればよい。このように、突き当て部５は、１カ所であってもよく、２カ所以上であってもよい。なお、突き当て部５が複数個所にあれば、デッキプレート用支持部材の向きや位置合わせなどが容易となるため望ましい。 In the above-described embodiment, an example in which the abutting portions 5 are located at two locations is shown, but the present invention is not limited to this. For example, as in the deck plate support member 1a shown in FIG. 7, the abutting portion 5 may be provided in one place. In this case as well, the portion other than the abutting portion 5 may be the welding receiving portion 7. As described above, the abutting portion 5 may be at one location or at two or more locations. It is desirable that the abutting portions 5 are provided at a plurality of locations because the orientation and alignment of the deck plate support members can be facilitated.
また、溶接受け部７も、連続した１カ所であってもよく、２カ所以上に分離されていてもよい。また、溶接受け部７は、デッキプレート支持部３と突き当て部５に対して斜めに形成されるのではなく、図８に示すデッキプレート用支持部材１ｂのように、段差状に折り曲げられた形状であってもよい。この場合でも、溶接受け部７の先端が、フランジ部１３の下方に突出するように形成されることが望ましい。 Further, the welding receiving portion 7 may also be a continuous one location, or may be separated into two or more locations. Further, the weld receiving portion 7 is not formed obliquely with respect to the deck plate supporting portion 3 and the abutting portion 5, but is bent in a stepped shape like the deck plate supporting member 1b shown in FIG. It may be in shape. Even in this case, it is desirable that the tip of the weld receiving portion 7 is formed so as to project downward from the flange portion 13.
