この発明は、上記のような技術的背景に基づいてなされたものであって、次の目的を達成するものである。
この発明の目的は、セパレータの構造が簡単であって、ユニットの組み立てを容易に短時間で行うことができ、施工コストを安価に抑えることができる型枠ユニット提供することにある。
The present invention has been made based on the technical background as described above, and achieves the following object.
An object of the present invention is to provide a mold unit that has a simple separator structure, can be easily assembled in a short time, and can reduce construction costs.

この発明は上記課題を解決するために、次のような手段を採用している。
すなわち、この発明は、2枚のパネルが複数のセパレータを介し相対して連結されてなる型枠ユニットであって、
前記セパレータは前記パネル間に配設されるパイプと、
該パイプの両端部にそれぞれ圧入固定されるアンカープラグと、
前記パネルを外側から貫通して前記アンカープラグにねじ込まれるタッピンネジとからなることを特徴とする型枠ユニットにある。
In order to solve the above problems, the present invention employs the following means.
That is, this invention is a mold unit in which two panels are connected to each other through a plurality of separators,
The separator is a pipe disposed between the panels;
Anchor plugs that are press-fitted and fixed to both ends of the pipe,
A formwork unit comprising a tapping screw that penetrates the panel from the outside and is screwed into the anchor plug.

より具体的には、前記パイプには前記アンカープラグの圧入固定部分に絞り部が設けられている。また、前記パネルは少なくとも一方の内側面に断熱材が積層されている構造とすることができる。   More specifically, the pipe is provided with a throttle portion at a press-fitting and fixing portion of the anchor plug. The panel may have a structure in which a heat insulating material is laminated on at least one inner surface.

この発明の型枠ユニットによれば、パネルをその間隔を保持した状態で連結するセパレータが、パネル間に配設されるパイプと、パイプの両端部に圧入固定されるアンカープラグと、パネルを貫通してアンカープラグにねじ込まれるタッピンネジとからなる極めて簡単な構造である。したがって、パネル間にパイプを配設して、アンカープラグにタッピンネジをねじ込ませるという極めて簡単な作業でユニットを組み立てることができ、施工コストを安価に抑えることができる。   According to the formwork unit of the present invention, the separator for connecting the panels in a state where the distance between the panels is maintained, the pipe disposed between the panels, the anchor plug press-fitted to both ends of the pipe, and the panel penetrated Thus, it has a very simple structure consisting of a tapping screw screwed into the anchor plug. Accordingly, it is possible to assemble the unit by an extremely simple operation of disposing a pipe between the panels and screwing the tapping screw into the anchor plug, and the construction cost can be suppressed at a low cost.

以下、この発明の型枠ユニットを実施するための最良の形態を図面に基づいて説明する。図1は、この発明による型枠ユニットのセパレータ部を詳細に示す断面図、図2は図1のX−X線断面図、図3は型枠ユニットの全体を示す外観図である。   The best mode for carrying out the formwork unit of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing in detail a separator portion of a mold unit according to the present invention, FIG. 2 is a sectional view taken along line XX of FIG. 1, and FIG. 3 is an external view showing the entire mold unit.

この発明の型枠ユニット1は、2枚のパネル2と、パネル2をその間隔を保持した状態で連結する複数(この実施形態では上下各2つで計4つ)のセパレータ3とからなる。   The formwork unit 1 according to the present invention includes two panels 2 and a plurality of separators 3 (four in total in this embodiment, two in each of the upper and lower sides) that connect the panels 2 in a state where the distance between the panels 2 is maintained.

パネル2は、薄い板材からなるもので、同一のサイズのものが2枚用いられる。パネル2の材質としては、永久型枠となることからセメント系,セラミックス系,自然石系、木質系などのものが選択される。この場合、2枚のパネル2に同じ材質のものを使用してもよいし、異なる材質のものを使用するようにしてもよい。   The panel 2 is made of a thin plate material, and two sheets having the same size are used. The material of the panel 2 is selected from cement-based, ceramic-based, natural stone-based, and wood-based materials because it is a permanent mold. In this case, the two panels 2 may be made of the same material or different materials.

パネル2の相対する上下方向の2つの縁辺には、他の型枠ユニット1のパネル2と継ぎ合わせるための相じゃくりによる継目4が形成されている。パネル2の4隅から少し離れた位置には、セパレータ3の構成要素の1つであるタッピンネジ5を通すためのネジ孔6が穿孔されている。このネジ孔6はパネル2の外側面側において大径の窪み7となっていて、この窪み7にタッピンネジ5の頭部が収容される(図1参照)。   On the two opposite vertical edges of the panel 2, a joint 4 is formed by a spigot for joining the panel 2 of another mold unit 1. At positions slightly apart from the four corners of the panel 2, screw holes 6 through which tapping screws 5, which are one of the components of the separator 3, are drilled. The screw hole 6 is a large-diameter recess 7 on the outer surface side of the panel 2, and the head of the tapping screw 5 is accommodated in the recess 7 (see FIG. 1).

セパレータ3は、図1に示すように、前述のタッピンネジ5と、パイプ8と、アンカープラグ9と、座金10とで構成される。タッピンネジ5,パイプ8,座金10の材質としては、耐腐食性のあるステンレス材が選択される。   As shown in FIG. 1, the separator 3 includes the aforementioned tapping screw 5, a pipe 8, an anchor plug 9, and a washer 10. As the material of the tapping screw 5, the pipe 8, and the washer 10, a corrosion-resistant stainless material is selected.

タッピンネジ5は、パネル2に設けられたネジ孔6を通過してパネル2の内側面から所要長さ突出するだけの軸長を有している。パイプ8は、コンクリートの打設の際の流動抵抗を低減するために丸管となっているが、角管でも構わない。パイプ8の軸長は、実質的(座金10の厚さも含まれる)に2枚のパネル2の相対する間隔を規定する。パイプ8の両端部には、湾曲した凹形に形成されて小径になった絞り部11が設けられている。   The tapping screw 5 has an axial length that passes through a screw hole 6 provided in the panel 2 and projects a required length from the inner surface of the panel 2. The pipe 8 is a round tube in order to reduce the flow resistance when placing concrete, but may be a square tube. The axial length of the pipe 8 substantially defines the relative distance between the two panels 2 (including the thickness of the washer 10). At both ends of the pipe 8, there are provided narrowed portions 11 formed in a curved concave shape and having a small diameter.

アンカープラグ9は合成樹脂製のものであり、市販もされている。このアンカープラグ9は、通常、コンクリートの壁や床などに機器類を取り付ける際に使用されている。すなわち、コンクリートの壁などに下穴をあけ、アンカープラグを圧入した後、このアンカープラグにタッピンネジをねじ込むことにより機器類を取り付けている。   The anchor plug 9 is made of a synthetic resin and is also commercially available. The anchor plug 9 is usually used when attaching equipment to a concrete wall or floor. That is, after drilling a pilot hole in a concrete wall or the like and press-fitting an anchor plug, devices are attached by screwing a tapping screw into the anchor plug.

この発明では、このような合成樹脂製のアンカープラグ9をパイプ8に圧入固定し、このアンカープラグ9にタッピンネジ5をねじ込むことにより、パイプ8とパネル2との一体化を図ったものである。このためアンカープラグ9はパイプ8に対する摩擦抵抗による所要の引抜き強度が要求される。この場合、パイプ8にステンレス製のものを使用すると、アンカープラグ9とパイプ8との間の大きな摩擦抵抗が得られない可能性がある。この問題は、アンカープラグ9が圧入固定されパイプの両端部に径を小さくした絞り部11を設けることによって解決される。   In the present invention, such an anchor plug 9 made of synthetic resin is press-fitted and fixed to the pipe 8 and the tapping screw 5 is screwed into the anchor plug 9 so that the pipe 8 and the panel 2 are integrated. For this reason, the anchor plug 9 is required to have a required pulling strength due to frictional resistance against the pipe 8. In this case, if a stainless steel pipe 8 is used, there is a possibility that a large frictional resistance between the anchor plug 9 and the pipe 8 cannot be obtained. This problem can be solved by providing the throttle plug 11 with the anchor plug 9 being press-fitted and fixed and having a reduced diameter at both ends of the pipe.

この発明の型枠ユニット1は、相対させた2枚のパネル2の間に座金10を介してパイプ8を配設し、タッピンネジ5をパネル3の外側からネジ孔6に挿通してアンカープラグ9にねじ込むことで組立てられる。組み立てられた型枠ユニット1においては、大きな引抜き強度を有するアンカープラグ9及びこれにねじ込まれるタッピンネジ9を介して、パネル2とパイプ8とが一体化されているので、パネル2どうしを確実に緊結することができる。   In the formwork unit 1 of the present invention, a pipe 8 is disposed between two opposed panels 2 via a washer 10, and a tapping screw 5 is inserted into the screw hole 6 from the outside of the panel 3 to fix the anchor plug 9. It can be assembled by screwing into. In the assembled formwork unit 1, since the panel 2 and the pipe 8 are integrated through the anchor plug 9 having a large pulling strength and the tapping screw 9 screwed into the anchor plug 9, the panels 2 are securely connected to each other. can do.

組立てられた型枠ユニット1は、図4に示すように、継目4を突き合わせて横方向に並列させ、さらに縦方向に積み上げ、内部に鉄筋を配筋したうえ、パネル2間に形成される空間にコンクリートが打設される。コンクリートの硬化後も型枠ユニット1は脱型されることなく、構造物の一部として使用される。   As shown in FIG. 4, the assembled formwork unit 1 is a space formed between the panels 2 by joining the joints 4 in parallel in the horizontal direction, further stacking in the vertical direction, and arranging reinforcing bars inside. Concrete is placed on the wall. The mold unit 1 is used as a part of the structure without being removed after the concrete is hardened.

図5には、この発明の型枠ユニット1の別の実施形態が示されている。この実施形態では、パネル2の内側面に発泡樹脂等の断熱材12を積層している。この実施形態による型枠ユニットは壁に適用され、断熱材12を一方のパネル2にのみ設ける構造とすることにより、外断熱構造にも内断熱構造にも構成することができる。   FIG. 5 shows another embodiment of the mold unit 1 of the present invention. In this embodiment, a heat insulating material 12 such as foamed resin is laminated on the inner surface of the panel 2. The formwork unit according to this embodiment is applied to a wall, and by providing a heat insulating material 12 only on one panel 2, it can be configured for both an outer heat insulating structure and an inner heat insulating structure.
