Description
本考案は「中空ボイドスラブ」領域に属する。コンクリート打設時に生ずる浮力と横力による球体ボイドの移動を拘束し上下のコンクリートかぶり厚を確保する拘束治具からなる移動防止金具である。 The present invention belongs to the “hollow void slab” region. It is a movement prevention bracket made up of a restraining jig that restrains the movement of spherical voids caused by buoyancy and lateral force generated when placing concrete and secures the upper and lower concrete cover thicknesses.
中空ボイドスラブを施工する際に、球体ボイドが治具内で十分に拘束されてない状態でコンクリートを打設するのが業界で行われてきた方式である。しかるに、図６
、図７にあるとおりコンクリート４を打設する際に生じる浮力Ｆ１と横力Ｆ２により、球体ボイドは拘束治具の緩みがあることから、浮き上がったり横移動したりした。また平行繋鉄線より上に球体ボイド頂部が浮上る例も見られ、球体ボイド上下のコンクリートかぶり厚Ｌ１、Ｌ２が著しく不均等なる品質上の問題があった。それを防ぐため、本考案者は球体ボイドの移動防止専用の「拘束治具」を考案した。この新考案の拘束治具により、球体ボイドはしっかりと拘束され、コンクリート打設時に浮力や横力による移動がなく、所定の位置に保ち上下のコンクリートかぶり厚を同じにでき、スラブの品質を格段に向上させることができる。
When constructing a hollow void slab, it has been practiced in the industry to place concrete in a state where the spherical void is not sufficiently restrained in the jig. However, FIG.
As shown in FIG. 7, due to the buoyant force F1 and lateral force F2 generated when placing the concrete 4, the spherical voids are lifted or moved laterally due to the looseness of the restraining jig. Moreover, the example which a spherical void top part floats above a parallel connecting iron wire was also seen, and there existed a quality problem that the concrete cover thickness L1 and L2 of the spherical void upper and lower sides were not quite uneven. In order to prevent this, the inventor has devised a "restraint jig" dedicated to preventing the movement of spherical voids. With this newly-developed restraint jig, the sphere voids are firmly restrained, there is no movement due to buoyancy or lateral force when placing concrete, and the concrete cover thickness at the top and bottom can be made the same, keeping the slab quality the same. Can be improved.
本考案の目的は、球体ボイドをコンクリート打設時に生ずる浮力や横力に抗し所定の位置に拘束しコンクリートの上下かぶり厚の均一性を維持することにある。 An object of the present invention is to maintain the uniformity of the top and bottom cover thickness of concrete by restraining a spherical void at a predetermined position against buoyancy and lateral force generated when placing concrete.
本考案の拘束治具から成る移動防止金具により、球体ボイドはしっかりと拘束され、コンクリート打設時に浮力や横力により移動することなく所定の位置に保ちスラブの品質を格段に向上させることができ。したがって、球体ボイドは左右上下で拘束治具に密着拘束されゆるみがなく、所定のコンクリートかぶり厚を維持することが出来る。 Due to the movement prevention bracket made up of the restraining jig of the present invention, the spherical void is firmly restrained, and it can be kept in place without moving by buoyancy or lateral force when placing concrete, and the quality of the slab can be greatly improved. . Therefore, the spherical void is tightly restrained by the restraining jig on the left, right, top and bottom and is not loosened, and a predetermined concrete cover thickness can be maintained.
図１から図４までに示した通り本考案は、球体ボイドのコンクリート打設時の移動を拘束することが出来る。平行繋鉄線３に、球体ボイド１を抱えた、複数の拘束治具２が溶接されている。本考案の特徴は、球体ボイド１と拘束治具２とがしっかりと密着し、緩みがないことである。 As shown in FIG. 1 to FIG. 4, the present invention can restrain the movement of the spherical void when placing concrete. A plurality of restraining jigs 2 holding a spherical void 1 are welded to the parallel connecting wire 3. The feature of the present invention is that the spherical void 1 and the restraining jig 2 are in close contact with each other and there is no looseness.
前述のごとく、拘束治具２の構成部品である1対の小円弧状の側円弧鉄線２１は球体ボイド１を両側から包み込みこんでいる。側円弧鉄線２１は球体ボイド１を横から拘束している。拘束治具２の下部部品である弧状底鉄線２２は球体ボイド１と同一半径を持つ弧状の鉄線で、左右の円弧側鉄線２１と最下部で溶接接合されている。 As described above, the pair of small arc-shaped side arc iron wires 21 which are components of the restraining jig 2 enclose the spherical void 1 from both sides. The side arc iron wire 21 constrains the spherical void 1 from the side. An arc-shaped bottom iron wire 22 which is a lower part of the restraining jig 2 is an arc-shaped iron wire having the same radius as the spherical void 1 and is welded to the left and right arc-side iron wires 21 at the bottom.
球体ボイド１と1対の円弧状側鉄線２１及び弧状底鉄線２２は密着してゆるみがない。前述のごとく拘束治具２の上部部品である頂部押鉄線２３は片側から丁度球体ボイド１の頂部中心を押さえつけるように調整されていて、上部で球体ボイドと密着しており安定的な拘束効果がある。
図にあるごとく、円弧側鉄線２１は上部で平行繋鉄線３に溶接固定されている、平行繋鉄線３が開かないよう留金物２４で平行繋鉄線の上から掛けて固定する。
The spherical void 1 and the pair of arcuate side iron wires 21 and arcuate bottom iron wires 22 are in close contact with each other and are not loosened. As described above, the top pushing wire 23 which is the upper part of the restraining jig 2 is adjusted so as to press the center of the top of the sphere void 1 from one side, and is in close contact with the sphere void at the upper portion, thereby providing a stable restraining effect. is there.
As shown in the drawing, the arc-side iron wire 21 is fixed to the parallel-connected iron wire 3 by welding on the parallel-connected iron wire 3 with a clasp 24 so that the parallel-connected iron wire 3 is not opened.
図５を参照して下さい。以上の構造によって拘束治具２の円弧側鉄線２１と弧状底鉄線２２及び上部開口側の頂部押鉄線２３とで球体ボイド１をしっかり拘束し緩みが無い。コンクリート打設時の球体ボイド１の浮上りと横移動が拘束され、上下のかぶり厚が均等に維持される。上述の詳細な説明は本考案の実例に即した具体例である。 Refer to FIG. With the above structure, the spherical void 1 is firmly restrained by the arc-side iron wire 21, the arc-shaped bottom iron wire 22 and the top pushing wire 23 on the upper opening side of the restraining jig 2, and there is no looseness. The floating and lateral movement of the spherical void 1 at the time of placing concrete are restrained, and the upper and lower cover thicknesses are maintained uniformly. The above detailed description is a specific example in accordance with an example of the present invention.
