Description

本発明は、建築物の鉄筋コンクリート中空スラブ内に埋設する軽量材から成る埋込体に係り、特に複数の軽量埋込体を並べたコンクリートスラブ用軽量埋込体の連設体に関するものである。   The present invention relates to an embedded body made of a lightweight material embedded in a reinforced concrete hollow slab of a building, and more particularly to a continuous body of lightweight embedded bodies for a concrete slab in which a plurality of lightweight embedded bodies are arranged.

従来から軽量材からなる埋込体をコンクリート内に埋設するコンクリート中空スラブ工法が知られている。これは、軽量材から成る埋込体を型枠板の上面であって縦横に配筋した上端筋及び下端筋の間に配置し、その後コンクリートを打設する工法である。これにより、埋込体が埋設された部分にコンクリート内に中空部が形成され、コンクリートスラブの軽量化を図ると共に遮音性等を向上させる。   2. Description of the Related Art Conventionally, a concrete hollow slab method in which an embedded body made of a lightweight material is embedded in concrete is known. This is a construction method in which an embedded body made of a lightweight material is disposed between upper and lower reinforcement bars arranged vertically and horizontally on the upper surface of a mold plate, and then concrete is placed. As a result, a hollow portion is formed in the concrete in the portion where the embedded body is embedded, thereby reducing the weight of the concrete slab and improving sound insulation and the like.

コンクリート内に埋込体を埋設する技術が種々提案されている。例えば特許文献１の特開２００３−３２１８９４公報「平面格子中空コンクリートスラブ及び押さえ金物」のように、埋込体として中空コンクリートスラブとこれに用いる押さえ金物が提案されている。   Various techniques for embedding embedded bodies in concrete have been proposed. For example, as disclosed in Japanese Patent Application Laid-Open No. 2003-321894 of “Patent Lattice Hollow Concrete Slab and Presser”, a hollow concrete slab and a presser used for this are proposed as an embedded body.

この特許文献１の押さえ金物は、隣り合う上端筋の間に平行に配置される少なくとも２本の補助筋と、補助筋に下向きに固着された複数のユニットで構成され、このユニットは格子状に配筋された上端筋が形成する小空間に装入され、軽量球体をこの小空間の所定位置に固定するようにした
1104974534140_0

特開２００３−３２１８９４ The presser foot of Patent Document 1 is composed of at least two auxiliary bars arranged in parallel between adjacent upper end bars, and a plurality of units fixed downward to the auxiliary bars. It was inserted into the small space formed by the arranged upper streak, and the lightweight sphere was fixed at a predetermined position in this small space.

JP 2003-321894 A

そこで、本発明の発明者は、図７の断面図に示すように、軽量埋込体５１の素材として発泡樹脂材に着目し、軽量埋込体５１を球体のような所定の形状に成型し、この軽量埋込体５１に略コ字形状の取付金具５２をその両先端から差し込み、この取付金具５２を２本の支持筋５３に間隔をあけて取り付け、軽量埋込体５１の連設体を構成する技術に着目した。   Therefore, as shown in the cross-sectional view of FIG. 7, the inventor of the present invention pays attention to the foamed resin material as the material of the lightweight implant 51, and molds the lightweight implant 51 into a predetermined shape such as a sphere. A substantially U-shaped mounting bracket 52 is inserted into the lightweight implant 51 from both ends, and the mounting bracket 52 is attached to the two support bars 53 with a space between them. We paid attention to the technology that composes.

しかし、支持筋５３に間隔をあけて取り付けた略コ字形状の取付金具５２は、軽量埋込体５１にその両先端部から差し込んでいるだけで、この軽量埋込体の連設体を乱暴に取り扱う際に、軽量埋込体５１が取付金具５２から簡単に抜けることがあった。一旦、取付金具５２から抜けた軽量埋込体５１を再度差し込んでも、軽量埋込体５１に開いた取付金具５２の挿通穴が緩くなって軽量埋込体５１が外れやすくなるという問題を有していた。   However, the substantially U-shaped mounting bracket 52 attached to the support bar 53 with a space is merely inserted into the lightweight implant 51 from both ends thereof, and the connected structure of the lightweight implant is roughly disturbed. In handling, the lightweight embedded body 51 may easily come off from the mounting bracket 52. Once the lightweight implant 51 that has come out of the mounting bracket 52 is inserted again, the insertion hole of the mounting bracket 52 opened in the lightweight implant 51 becomes loose and the lightweight implant 51 is likely to come off. It was.

このように一旦軽量埋込体５１が外れやすくなった連設体は、これを上端筋及び下端筋の間に配置する際にも、軽量埋込体５１が外れて作業のやり直しが多くなり配置作業が煩雑になりやすいという問題を有していた。   As described above, the continuous body in which the lightweight implant 51 is easily detached once is arranged so that the lightweight implant 51 is detached and the work is re-executed even when it is disposed between the upper and lower reinforcements. There was a problem that the work was likely to be complicated.

本発明は、かかる問題点を解決するために創案されたものである。すなわち、本発明の目的は、取付金具の一部を曲がりやすくすることで、軽量埋込体に取付金具を差し込むだけで、この取付金具を軽量埋込体に強固に固定することができるコンクリートスラブ用軽量埋込体の連設体を提供することにある。   The present invention has been developed to solve such problems. That is, an object of the present invention is to make a part of the mounting bracket easy to bend, so that the mounting bracket can be firmly fixed to the lightweight implant by simply inserting the mounting bracket into the lightweight implant. Another object of the present invention is to provide a continuous assembly of lightweight embedded bodies for use.

本発明によれば、コンクリート内に埋設する軽量材からなる複数の軽量埋込体（１）と、前記軽量埋込体（１）内に差し込むために、先端部（３）が下向きになるように線材（２）を略コ字形状に形成した取付金具（４）と、前記取付金具（４）を複数並列させて取り付けた支持筋（５）と、を備え、各取付金具（４）が各軽量埋込体（１）から抜けないように、該取付金具（４）を先端部（３）から該軽量埋込体（１）に差し込むときに、前記線材（２）の途中が曲折するように構成した、ことを特徴とするコンクリートスラブ用軽量埋込体の連設体が提供される。
前記軽量埋込体（１）は発泡樹脂材からなる埋込体である。 According to the present invention, a plurality of lightweight implants (1) made of a lightweight material to be embedded in concrete, and the tip (3) face down to be inserted into the lightweight implant (1). And a support bar (5) in which a plurality of the mounting brackets (4) are mounted in parallel, each mounting bracket (4) having a wire rod (2) formed in a substantially U-shape. When the mounting bracket (4) is inserted into the lightweight implant (1) from the tip (3) so that it does not come out from each lightweight implant (1), the wire (2) is bent halfway. There is provided a continuous structure of a lightweight embedded body for concrete slabs configured as described above.
The lightweight embedded body (1) is an embedded body made of a foamed resin material.

前記取付金具（４）は、各先端部（３）に傾斜した切断面（６）を形成すると共に、該取付金具（４）が曲折しやすいように、前記線材（２）の途中に曲折契機部（７）を形成したものである。
前記取付金具（４）の先端部（３）に形成した両切断面（６）の傾斜方向が異なる方向である。 The mounting bracket (4) forms an inclined cut surface (6) at each tip end portion (3), and is bent in the middle of the wire rod (2) so that the mounting bracket (4) can be easily bent. Part (7) is formed.
The inclined directions of both cut surfaces (6) formed at the tip (3) of the mounting bracket (4) are different directions.

上述したように、本発明では、各軽量埋込体（１）に取付金具（４）を差し込む際に、取付金具（４）の先端部（３）が該軽量埋込体（１）内を侵入しているときに直進方向から外れて線材（２）の途中が曲折し、取付金具（４）が軽量埋込体（１）から抜けないようになる。そこで、この軽量埋込体（１）を取付金具（４）に強固に固定することができる。特に、取付金具（４）が下向きの略コ字形状になり、各先端部（３）の傾斜した切断面（６）が軽量埋込体（１）内で曲がりやすいので、取付金具（４）を軽量埋込体（１）に容易に差し込むことができる。軽量埋込体の連設体を迅速に組み立てることができる。   As described above, in the present invention, when the mounting bracket (4) is inserted into each lightweight implant (1), the tip (3) of the mounting bracket (4) is placed inside the lightweight implant (1). When invading, it deviates from the straight direction and the wire (2) is bent in the middle, so that the mounting bracket (4) cannot be removed from the lightweight implant (1). Therefore, the lightweight implant (1) can be firmly fixed to the mounting bracket (4). In particular, the mounting bracket (4) has a substantially U-shape downward, and the inclined cut surface (6) of each tip (3) is easy to bend in the lightweight implant (1). Can be easily inserted into the lightweight implant (1). A continuous assembly of lightweight implants can be quickly assembled.

特に、取付金具（４）は、線材（２）の途中に曲折契機部（７）を形成したものでは、取付金具（４）を軽量埋込体（１）に差し込む際に先端部（３）を確実に曲折させることができる。   In particular, in the case where the mounting bracket (4) has a bending trigger portion (7) formed in the middle of the wire (2), the distal end portion (3) when the mounting bracket (4) is inserted into the lightweight implant (1). Can be bent reliably.

本発明は、コンクリート内に埋設する軽量材からなる複数の軽量埋込体と、軽量埋込体内に差し込めると共に曲がりやすい線材を略コ字形状に形成した取付金具と、複数の取付金具を並列させて取り付けた支持筋とを備えたコンクリートスラブ用軽量埋込体の連設体である。   The present invention includes a plurality of lightweight implants made of a lightweight material embedded in concrete, a mounting bracket that is inserted into the lightweight implant and that is easily bent and formed into a substantially U-shape, and a plurality of mounting brackets in parallel. It is the continuous installation body of the lightweight embedded object for concrete slabs provided with the supporting reinforcement attached by doing.

以下、本発明の好ましい実施の形態を図面を参照して説明する。
図１は実施例１のコンクリートスラブ用軽量埋込体の連設体の正面図である。図２は実施例１のコンクリートスラブ用軽量埋込体の連設体の平面図である。図３は実施例１のコンクリートスラブ用軽量埋込体に取付金具を差し込んだ状態の断面図である。
本発明のコンクリートスラブ用軽量埋込体の連設体は、コンクリート内に埋設する軽量材からなる複数の軽量埋込体１と、この軽量埋込体１内に差し込めるように線材２の先端部３を下向きに略コ字形状に形成した取付金具４と、２本１組の取付金具４を複数間隔をあけて取り付けた２本の線材を並行に並べた支持筋５とを備えたものである。この軽量埋込体１は、発泡スチロールのような軽量な発泡樹脂材からなる。図示例では、１個の軽量埋込体１を２本１組の取付金具４で固定しているが、支持筋５に固定することができると共に、軽量埋込体１が不用意に外れないものであれば、取付金具４は２本１組に限定されない。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a continuous body of lightweight embedded bodies for concrete slabs of Example 1. FIG. FIG. 2 is a plan view of a continuous body of lightweight embedded bodies for concrete slabs of Example 1. FIG. FIG. 3 is a cross-sectional view of a state in which a mounting bracket is inserted into the lightweight embedded body for a concrete slab of the first embodiment.
A continuous body of lightweight embedded bodies for concrete slabs according to the present invention includes a plurality of lightweight embedded bodies 1 made of a lightweight material embedded in concrete, and a tip of a wire 2 so as to be inserted into the lightweight embedded body 1. A mounting bracket 4 in which the portion 3 is formed in a substantially U-shape downward, and a support bar 5 in which two wire rods each having a pair of mounting brackets 4 mounted at intervals are arranged in parallel. It is. The lightweight implant 1 is made of a lightweight foamed resin material such as expanded polystyrene. In the illustrated example, one lightweight implant 1 is fixed by a set of two mounting brackets 4, but can be fixed to the support bar 5 and the lightweight implant 1 does not come off carelessly. If it is a thing, the attachment metal fitting 4 is not limited to 1 set of 2 pieces.

このように構成した軽量埋込体１の連設体は、型枠板の上面であって縦横に配筋した上端筋及び下端筋の間に配置し、その後コンクリートを打設する。この軽量埋込体１は埋設された部分にコンクリート内に中空部が形成され、コンクリートスラブの軽量化を図ることができるものであれば、発泡樹脂材の空隙率は限定されない。なお、図示例では３個の軽量埋込体１を支持筋５に連設した状態であるがこの個数に限定されない。   The continuous structure of the lightweight embedded body 1 configured as described above is disposed between the upper and lower reinforcing bars arranged vertically and horizontally on the upper surface of the mold plate, and then concrete is placed. As long as this lightweight embedded body 1 has a hollow portion formed in the embedded part and can reduce the weight of the concrete slab, the porosity of the foamed resin material is not limited. In the illustrated example, three lightweight implants 1 are connected to the support muscle 5, but the number is not limited thereto.

図４は実施例１のコンクリートスラブ用軽量埋込体に差し込む前の取付金具の拡大正面図である。
本発明の取付金具４は、軽量埋込体１に差し込む際に、この取付金具４の先端部３が軽量埋込体１内を侵入しているときに直進方向から外れ、線材２の途中が曲折して、取付金具４が軽量埋込体１から抜けないようになっている。例えば、取付金具４は、下向きの各先端部３に傾斜した切断面６を形成すると共に、取付金具４が曲折しやすいように線材２の途中に曲折契機部７を形成したものである。この先端部３に傾斜した切断面６は、取付金具４を軽量埋込体１内に差し込むときに直進方向から外れて線材２の途中を曲折させる機能を有する。また、線材２の途中に形成した曲折契機部７は、取付金具４の線材２を曲折しやすくする機能を有する。このように本発明では、取付金具４を軽量埋込体１内に差し込んだときにのみ、取付金具４の一部が曲折するように構成したので、取付金具４を軽量埋込体１に容易に差し込みやすく迅速に軽量埋込体１の連設体を組み立てることができる。
なお、曲折契機部７は線材２の一部を切り欠いて機械的強度を低下させた部位であるが、曲折契機部７は線材２の一部に予め折り目を入れておいたものでもよい。 FIG. 4 is an enlarged front view of the mounting bracket before being inserted into the lightweight embedded body for concrete slab of the first embodiment.
When the mounting bracket 4 of the present invention is inserted into the lightweight implant 1, the mounting bracket 4 comes off from the straight direction when the tip 3 of the mounting bracket 4 enters the lightweight implant 1, and the middle of the wire 2 It is bent so that the mounting bracket 4 cannot be removed from the lightweight implant 1. For example, the mounting bracket 4 is formed by forming an inclined cut surface 6 at each tip portion 3 facing downward, and forming a bending trigger portion 7 in the middle of the wire 2 so that the mounting bracket 4 is easily bent. The cut surface 6 inclined to the distal end portion 3 has a function of bending the wire 2 in the middle of the straight wire 2 when the mounting bracket 4 is inserted into the light weight embedded body 1. Moreover, the bending trigger part 7 formed in the middle of the wire 2 has a function of easily bending the wire 2 of the mounting bracket 4. As described above, in the present invention, since the mounting bracket 4 is configured to bend only when the mounting bracket 4 is inserted into the lightweight implant 1, the mounting bracket 4 can be easily attached to the lightweight implant 1. It is easy to insert into the light-emitting device, and the continuous assembly of the lightweight implants 1 can be assembled quickly.
In addition, although the bending opportunity part 7 is a site | part which notched a part of the wire 2 and reduced the mechanical strength, the bending opportunity part 7 may have put a crease in a part of the wire 2 beforehand.

図５は実施例１の取付金具を軽量埋込体に差し込む状態を示すものであり、（ａ）は取付金具の先端部を軽量埋込体に差し込む状態の断面図、（ｂ）は取付金具が曲折していく状態の断面図、（ｃ）は取付金具を最後まで差し込んだ状態の断面図である。
本発明の取付金具４が軽量埋込体１内で曲折する状態を説明する。先ず、図５（ａ）に示すように、下向きの略コ字形状の線材２からなる取付金具４を軽量埋込体１に、各先端部３から差し込む。取付金具４の先端部３には傾斜した切断面６が形成されているので、容易に取付金具４を差し込むことができる。
次に、図５（ｂ）に示すように、取付金具４はその先端部３には傾斜した切断面６が軽量埋込体１内を突き進むときに、この切断面６が抵抗になって直進できなくなる。図示上では２本の先端部が内側に傾斜していく。更に、本発明では取付金具４の線材２の途中に曲折契機部７を形成してあるので、この曲折契機部７部分で容易にかつ確実に曲折する。
最後に、図５（ｃ）に示すように、略コ字形状の取付金具４を軽量埋込体１に最後まで差し込むと取付金具４の曲折契機部７で大きく曲折する。このように線材２に曲折部分があるために、取付金具４が軽量埋込体１から抜けにくくなる。 FIG. 5 shows a state in which the mounting bracket of Example 1 is inserted into the lightweight implant, (a) is a cross-sectional view of a state in which the tip of the mounting bracket is inserted into the lightweight implant, and (b) is a mounting bracket. Is a cross-sectional view in a state in which the metal plate is bent, and (c) is a cross-sectional view in a state in which the mounting bracket is inserted to the end.
A state in which the mounting bracket 4 of the present invention is bent in the lightweight implant 1 will be described. First, as shown in FIG. 5 (a), a mounting bracket 4 made of a substantially downward U-shaped wire 2 is inserted into the lightweight implant 1 from each tip 3. Since the inclined cutting surface 6 is formed at the distal end portion 3 of the mounting bracket 4, the mounting bracket 4 can be easily inserted.
Next, as shown in FIG. 5 (b), when the cutting surface 6 inclined at the tip 3 of the mounting bracket 4 advances through the lightweight implant 1, the cutting surface 6 becomes a resistance and goes straight. become unable. In the drawing, the two tip portions are inclined inward. Furthermore, since the bending trigger part 7 is formed in the middle of the wire 2 of the mounting bracket 4 in the present invention, the bending trigger part 7 is easily and reliably bent.
Finally, as shown in FIG. 5 (c), when the substantially U-shaped mounting bracket 4 is inserted into the lightweight implant 1 to the end, it is bent greatly at the bending trigger portion 7 of the mounting bracket 4. Thus, since the wire 2 has a bent portion, the mounting bracket 4 is difficult to be removed from the lightweight implant 1.

本発明では、取付金具４は支持筋５に固定しやすいよういに、下向きの略コ字形状の線材２を用いているが、軽量埋込体１にその先端部３から差し込みやすい形状であれば、この略コ字形状に限定されない。また、取付金具４の先端部３は、軽量埋込体１内を突き進むときに抵抗を受けて傾斜しやすいように、傾斜した切断面６としている。しかし、このように抵抗を受けて傾斜しやすい形状であれは、傾斜した切断面６以外に、例えば、先端部３に傾斜したウィングのような抵抗部材（図示していない）を取り付けることも可能である。   In the present invention, the mounting bracket 4 uses a downwardly substantially U-shaped wire 2 so that it can be easily fixed to the support bar 5. However, the mounting bracket 4 may be easily inserted into the lightweight implant 1 from its distal end portion 3. For example, it is not limited to this substantially U shape. In addition, the distal end portion 3 of the mounting bracket 4 is formed as an inclined cut surface 6 so as to be easily inclined due to resistance when proceeding through the lightweight implant 1. However, if the shape is easy to tilt due to resistance in this way, it is possible to attach a resistance member (not shown) such as a tilted wing to the tip 3 in addition to the tilted cut surface 6. It is.

図６は実施例２の取付金具の正面図である。
実施例２では、取付金具４の先端部３に形成した両切断面６の傾斜方向が内側になっている。このように構成した取付金具４は、両切断面６は軽量埋込体１内を突き進むときに抵抗を受けて外側に曲折するようになる。本発明では取付金具４の先端部３が曲折して、軽量埋込体１から抜けづらくなる形状であれば、上述した傾斜方向に限定されない。 FIG. 6 is a front view of the mounting bracket of the second embodiment.
In Example 2, the inclination direction of both the cut surfaces 6 formed in the front-end | tip part 3 of the attachment metal fitting 4 is inside. The mounting bracket 4 configured in this manner is bent outward due to resistance when both cut surfaces 6 push through the lightweight implant 1. In this invention, if the front-end | tip part 3 of the attachment metal fitting 4 bends and it is a shape which becomes difficult to remove | deviate from the lightweight embedded body 1, it will not be limited to the inclination direction mentioned above.

なお、本発明は上述した発明の実施の形態に限定されず、取付金具４を曲がりやすくすることで、軽量埋込体１に取付金具４を差し込むだけで、この軽量埋込体１を取付金具４で強固に固定することができる構成であれば、図示したような構成に限定されず、本発明の要旨を逸脱しない範囲で種々変更できることは勿論である。   In addition, this invention is not limited to embodiment of the invention mentioned above, By making the attachment metal fitting 4 easy to bend, only by inserting the attachment metal fitting 4 into the light weight implantation object 1, this lightweight implant 1 is attached to the attachment metal fitting. Of course, as long as the configuration can be firmly fixed at 4, it is not limited to the configuration shown in the figure, and it is needless to say that various modifications can be made without departing from the gist of the present invention.

本発明のコンクリートスラブ用軽量埋込体の連設体は、コンクリートスラブを軽量化するために、このコンクリートスラブ内に埋設するだけでなく、その他の打設するコンクリートを軽量化するような様々な用途に利用することができる。   In order to reduce the weight of the concrete slab, the continuous structure of the light weight embedded body for the concrete slab of the present invention is not only embedded in the concrete slab but also various other types of lightening the concrete to be placed. Can be used for applications.
