Abstract
この特許の目的は、普通建設のため、特にそれはハンガ(4)折り曲げ時に発生する多角形にそれらの製造過程で非同一平面エッジが発生することを防止し、これが工程に大きな節約をもたらすので、強化構造のためのハンガ(4)生産のための曲げ加工を目的とした棒鋼(2)製造技術における技術状態の進歩にある。非同一平面エッジもったハンガ(4)の形成は、普通建設に費用と遅れをもたらし、これはこの特許の目的である、普通建設専用八角芯を持った棒鋼の使用により回避することができる。普通建設専用八角芯を持った棒鋼の芯は、図8のように八角形であるが、その固有断面は、図9のように棒鋼(2)が作られる波型材により形成される八角構造である。
The purpose of this patent is for normal construction, especially because it prevents polygons generated during hanger (4) folding from generating non-coplanar edges in their manufacturing process, which results in significant savings in the process, The state of the art in the steel bar (2) manufacturing technology for the purpose of bending for the production of hangers (4) for reinforced structures. The formation of hangers (4) with non-coplanar edges brings cost and delay to normal construction, which can be avoided by the use of steel bars with a regular construction octagonal core, the purpose of this patent. The core of a steel bar with an octagonal core dedicated to ordinary construction is octagonal as shown in Fig. 8, but its intrinsic cross section is an octagonal structure formed by a corrugated material from which steel bar (2) is made as shown in Fig. 9. is there.
Description
普通建設は強化コンクリート技術を採用したので、柱生産は手作業工程であり垂直ボックスはそれらの内部に適当な長い棒鋼を入れて立てられる;これらの箱は、所謂コンクリートが構成される水、砂及び破砕石を混ぜたセメントで充満される。 Since ordinary construction has adopted reinforced concrete technology, column production is a manual process, and vertical boxes are erected with suitable long steel bars inside them; these boxes are water, sand, which constitutes so-called concrete And filled with cement mixed with crushed stone.
図1,2及び3にこの工程及びその段階を示す。
図1で工程の最初の段階が見られ、ここでは棒鋼(2)が何らかの支持台(12)上に垂直に配置され、それら自身の剛性により所定の位置に保たれ、又はそれらは針金(3)で結束される。
1, 2, and 3 illustrate this process and its stages.
The first stage of the process can be seen in FIG. 1, in which the steel bars (2) are placed vertically on some support base (12) and are kept in place by their own rigidity, or they are made of wire (3 ).
図2で棒鋼はハンガ(4)で所定位置に保持され、通常は構造計画によるが、これは何番でもよく、そしてこれらはまた棒鋼と同じ鋼でできており、そして溶接又は針金結束のいずれかにより棒鋼に固定される。
図3は建築中の柱(5)の一般的正面図であり、そしてこの段階でそれは木型(6)で包まれ、その正面部は柱の内部を露出させるため省略され、それらはその内部に配置されるコンクリートが固まれば除去される。
ハンガ(4)は通常主鉄筋のそれより小さい寸法を有し、そしてそれらは、図4により上面からハンガを見る、ここでは長方形の適当な寸法と形状でそれら自身の切断及び折り曲げにより得られる;しかしそれは正方形、三角形、六化形等のそれのような他の多角形状でもよい。
棒鋼として使用される市場により提供される原材料は、通常図5で示すように丸芯棒と呼ばれる固有断面(7)、および図6に示すように波形表面として知られる固有表面(8)を有する。これらの固有形状及び表面はコンクリートと棒鋼(2)及びハンガ(4)の接触面及び接着性を増加させそして全体の抵抗を上げることを目的とする。
しかし棒鋼(2)がハンガ(4)を作るために折り曲げられる場合、材料の固有断面のため、形成される多角形(9)は、丸芯の固有形状が期待されるそれらと異なる角度で変形するため、図7により同じ平面にエッジを保持しない。このような状況は再度同一平面にエッジを有するように棒鋼を針金にて結束するために、通常二人の作業員が必要とされるため、コストを上昇させそして建設工期を長引かせる。
In FIG. 2, the steel bar is held in place by a hanger (4), usually according to the structural plan, but this can be any number, and these are also made of the same steel as the steel bar, and either welding or wire binding It is fixed to the steel bar.
FIG. 3 is a general front view of a pillar (5) under construction, and at this stage it is wrapped in a wooden mold (6), whose front is omitted to expose the interior of the pillar, they are Once the concrete placed in is hardened, it is removed.
The hangers (4) usually have dimensions smaller than that of the main rebar, and they are seen from the top according to FIG. 4, where they are obtained by cutting and bending themselves with suitable dimensions and shapes of rectangles; However, it can be other polygonal shapes such as squares, triangles, hexagons etc.
The raw materials offered by the market used as steel bars usually have a natural cross section (7) called round core bar as shown in FIG. 5 and a natural surface (8) known as corrugated surface as shown in FIG. . These inherent shapes and surfaces are intended to increase the contact surface and adhesion of concrete and steel bars (2) and hangers (4) and increase the overall resistance.
However, when the steel bar (2) is bent to make the hanger (4), due to the inherent cross-section of the material, the formed polygon (9) is deformed at an angle different from those expected for the natural shape of the round core. Therefore, the edges are not held in the same plane as shown in FIG. Such a situation increases the cost and lengthens the construction period because two workers are usually required to bind the steel bars with wires so as to have edges on the same plane again.
その芯の八角形状による、この特許の目的「普通建設専用八角芯を持った棒鋼」は手作業または工業的に折り曲げられる時、ハンガが明確な平面にエッジを有するようにする角度を形成させない様にする。 Due to the octagonal shape of its core, the purpose of this patent "bars with a regular construction octagonal core" does not form an angle that causes the hanger to have an edge in a clear plane when folded manually or industrially To.
図8は「普通建設専用八角芯を持った棒鋼」(1)の八角形状(10)を示し、そして図9はその固有波型表面に由来するその固有断面(11)を示す。
図10は色々な断面形状から手作業および工業的に棒鋼を折り曲げる場合、加えられる力のシステムを示す:棒鋼(2)は固定具(12)と(12A)により折り曲げボルト上の正しい位置に配置される;この点でそれは力(14)の作用により折り曲げられる。
FIG. 8 shows the octagonal shape (10) of “bars with octagon cores for ordinary construction” (1), and FIG. 9 shows its natural cross section (11) derived from its natural wave surface.
Figure 10 shows the system of force applied when manually and industrially bending steel bars from various cross-sectional shapes: Steel bar (2) is positioned in the correct position on the folding bolt by fasteners (12) and (12A) At this point it is folded by the action of force (14).
図11は得られた結果を正面図で示す;期待される結果は点ABDにより規定される直線状のそれらであるが、実際上直線ABC及びABEで形成される角度で統計的に分散した折り曲げが得られ、そして、正方形ハンガ(4)の形成において、これらのような四つのランダム分散が付加され、その結果ハンガ(4)は指摘したような経過で同一平面にならないことは明確である。 FIG. 11 shows the results obtained in a front view; the expected results are those of a straight line defined by the point ABD, but in practice a fold distributed statistically at angles formed by the straight lines ABC and ABE. And in the formation of the square hanger (4), four random dispersions like these are added, so that the hanger (4) does not become coplanar in the course as indicated.
この理由は明らかであり:円盤形状の棒鋼(2)を折り曲げる場合、折り曲げ力に対向する抵抗は直径の均一性ため、あらゆる方向で同一であり;八角形状棒鋼(2)について、このような多角形の対向側の平行性により棒鋼は図12により固定具(12)及び(12A)により折り曲げボルト(13)上にしっかりと正しく配置され、そして多角形の辺心距離に相当する切断面H・・・Iの領域はその対角線に相当するF・・・Gより小さく、このため作用力に対し最も小さな抵抗を持った領域であり、そしてそれは折り曲げが効率的に起こり、その結果同一平面ハンガ(4)ができる。 The reason for this is clear: when bending a disk-shaped steel bar (2), the resistance against the bending force is the same in all directions due to the uniformity of the diameter; Due to the parallelism of the opposite sides of the square, the steel bar is firmly positioned correctly on the bending bolt (13) by the fixtures (12) and (12A) according to FIG. .. The area of I is smaller than F ... G corresponding to the diagonal line, and is therefore the area having the smallest resistance to the acting force, and that the folding occurs efficiently, with the result that the coplanar hanger ( 4) is possible.
