この考案は手摺柵の支柱に関し、アルミ合金等、不銹金
属製手摺柵支柱を、その外観を変えず、また電食のおそ
れなく鋼材により補強することを目的とする。[Detailed description of the invention] The purpose of this invention is to reinforce handrail fence posts made of non-corrosive metal such as aluminum alloy with steel without changing the appearance or without fear of electrolytic corrosion. .
この考案の概要は、中空の手摺柵支柱内に補強用鋼柱を
納め、間隔片をはさみ二個所で固定し、上端は中空支柱
だけ笠木に固定し、補強柱下端を露出させるもので、外
観は従来と変らないが、電食のおそれなく充分補強され
る。The outline of this idea is to house a reinforcing steel column inside a hollow handrail fence post, fix the spacing piece in two places with scissors, fix the upper end of the hollow column only to the cap, and expose the lower end of the reinforcing column. is the same as before, but is sufficiently reinforced without the risk of electrolytic corrosion.
露出した補強柱下端は建物躯体に埋めたアンカープレー
トや鉄筋に溶接できるので、現場作業を簡易化する。The exposed lower ends of the reinforcement columns can be welded to the anchor plates and reinforcing bars buried in the building frame, simplifying on-site work.
以下、図示した実施例によって、この考案の構成を説明
する。The configuration of this invention will be explained below with reference to the illustrated embodiments.
図の1はアルミ合金製外装中空柱、2は鋼製内部補強柱
で、中空柱1の内周との間に絶縁間隙3をもち、中空柱
1下端から露出した部分2aを床コンクリートにより固
定される。In the figure, 1 is an aluminum alloy exterior hollow column, 2 is a steel internal reinforcement column, which has an insulating gap 3 between it and the inner circumference of the hollow column 1, and the part 2a exposed from the lower end of the hollow column 1 is fixed with floor concrete. be done.
この場合、中空柱1は内面に、押出成形時、作られたネ
ジ嵌合溝4を通している。In this case, the hollow column 1 has a screw fitting groove 4 formed during extrusion molding passed through the inner surface thereof.
この実施例の上記間隙3は充分広いので、第2図に示す
ように中空柱1内面に突出させた上記嵌合溝4の両縁も
補強柱2に触れず、電食の危険を完全に予防している。Since the gap 3 in this embodiment is sufficiently wide, both edges of the fitting groove 4 protruding from the inner surface of the hollow column 1 do not touch the reinforcing column 2 as shown in FIG. 2, completely eliminating the risk of electrolytic corrosion. It is being prevented.
しかし、間隙3がさほど広くないか、広くても使用中の
移動により嵌合溝4上縁が補強柱2表面に線接触しても
実害はない。However, even if the gap 3 is not so wide or wide, there is no actual harm even if the upper edge of the fitting groove 4 comes into line contact with the surface of the reinforcing column 2 due to movement during use.
異種金属が面接触して間隙に水分をとどめる場合には電
食が生ずるのであって、線接触では水分が流下蒸発して
電食に必要な水分が残留しないからである。Electrolytic corrosion occurs when dissimilar metals come into surface contact and moisture remains in the gap, whereas in line contact, the moisture flows down and evaporates, leaving no moisture necessary for electrolytic corrosion.
その線接触面に防錆処理、塗装等を施してあれば、さら
に安全である。It will be even safer if the wire contact surface is treated with anti-corrosion treatment, painting, etc.
第1図の各部品が組立てられたところを第3図に示す。FIG. 3 shows how the parts shown in FIG. 1 are assembled.
この場合、中空柱1は上端に固定した笠木取付金具6を
介して笠木(上梓)5に固定されている。In this case, the hollow column 1 is fixed to a Kasagi (upper Azusa) 5 via a Kasagi mounting bracket 6 fixed to the upper end.
そして、その取付金具6は下面に補強柱2上端に面接触
なく入込む突出部7をもっている。The mounting bracket 6 has a protrusion 7 on its lower surface that enters the upper end of the reinforcing column 2 without surface contact.
もつとも、取付金具6がステンレス鋼で、中空柱1がア
ルミ合金の場合は面接触でも害はない。However, if the mounting bracket 6 is made of stainless steel and the hollow column 1 is made of aluminum alloy, there is no harm in surface contact.
また中空柱1は手摺下枠8の高さにおいて、絶縁間隙3
に介入させた絶縁性間隔片9を中空柱1両側のT枠受金
具10と共に貫通支持する締付ボルト、ナツト11を備
え、さらに中空柱1の下端近くを補強柱2もろ共貫通し
絶縁間隙3に介入させた絶縁性間隔片9を固定するボル
ト、ナツト12を備える。In addition, the hollow pillar 1 has an insulating gap 3 at the height of the handrail lower frame 8.
Tightening bolts and nuts 11 are provided to penetrate and support the insulating spacing piece 9 interposed in the hollow column 1 together with the T-frame holder 10 on both sides of the hollow column 1, and the reinforcing column 2 also penetrates near the lower end of the hollow column 1 to form an insulating gap. 3 are provided with bolts and nuts 12 for fixing the insulating spacing piece 9 interposed therebetween.
第1,3図の実施例の笠木5は背板、腹板が一体のもの
であるから、取付金具6の上に載せ、下から止ネジ13
により固定すること、従来と変りない。Since the cap 5 of the embodiment shown in FIGS. 1 and 3 has a back plate and a belly plate integrated, it is placed on the mounting bracket 6 and set screws 13 are inserted from below.
This is the same as before.
その前に取付金具6は、押込ネジ14を支柱1の嵌合溝
4へねじ込んで沖空柱1に固定しておく。Before that, the mounting bracket 6 is fixed to the offshore column 1 by screwing the push screw 14 into the fitting groove 4 of the column 1.
外装中空柱1と補強柱2との締付固定部は、外装中空柱
1両側に間隔片9が入込む穴、補強柱2両側にボルトが
触れずに通るだけの穴が同心に設けられており、外装中
空柱1両側の穴へ挿入した上記各穴と同軸のボルト穴つ
き間隔片9と、この間隔片9と外装中空柱穴縁とを共に
抑える両側の座金15と、上記各穴、座金を貫通して締
付固定するボルト、ナツトとからなる。The tightening and fixing part between the exterior hollow column 1 and the reinforcement column 2 is provided concentrically with holes into which the spacing pieces 9 enter on both sides of the exterior hollow column 1 and holes through which bolts can pass through without touching on both sides of the reinforcement column 2. A spacing piece 9 with a bolt hole coaxial with each of the holes inserted into the holes on both sides of the exterior hollow column 1, washers 15 on both sides that hold the spacing piece 9 and the edge of the exterior hollow column hole together, and each of the holes, Consists of bolts and nuts that pass through the washer and are tightened and fixed.
こうして中空柱1、補強柱2を正しい関係位置に組立て
、所要床面に立てて補強柱2の露出端をアンカープレー
ト、鉄筋等に溶接し、床コンクリートFを打設して固定
する。In this way, the hollow column 1 and the reinforcing column 2 are assembled in the correct relative positions, erected on the required floor surface, the exposed end of the reinforcing column 2 is welded to an anchor plate, reinforcing steel, etc., and floor concrete F is poured and fixed.
第′3図は補強柱露出部2aも、中空柱1も共にコンク
リートにより強力に固定された例で、この場合中空柱1
は補強柱2を入れない従来のもの同様、それ自身でも中
空柱1の屈曲耐力に見合う強さで片持支持される。Figure '3 shows an example in which both the reinforced column exposed part 2a and the hollow column 1 are strongly fixed with concrete.
As with the conventional structure without the reinforcing column 2, the hollow column 1 is cantilever-supported by itself with a strength corresponding to the bending strength of the hollow column 1.
しかし、支柱としての水平荷重耐力を大部分、補強柱2
にまかせ、例えば中空柱1は薄肉、その下端は軽くコン
クリ−)F面に埋まっただけにする事もあり得る。However, most of the horizontal load bearing capacity as a support column is
For example, the hollow column 1 may have a thin wall and its lower end may be lightly buried in surface F (concrete).
氷炭荷重で中空柱1内面が補強柱2に触れ面接触となる
場合は電食を起すので、接触しそうな位置に予め絶縁材
を接着その他の方法で絶縁間隙3へ介在させてもよい。If the inner surface of the hollow column 1 comes into surface contact with the reinforcing column 2 due to the icy coal load, electrolytic corrosion will occur, so an insulating material may be placed in advance in the insulation gap 3 by gluing or other method at a position where contact is likely to occur.
しかし、この実施例はネジ嵌合溝4の存在により接して
も線接触であるから、その必要がない。However, in this embodiment, due to the presence of the screw fitting groove 4, even if they make contact, it is a line contact, so this is not necessary.
上記実施例は可能性のある付属物を種々取付けているが
、取付金具突出部7を省略し、笠木5への水平荷重が中
空柱1上部を介して補強柱2へ加わるようにしてもよい
。In the above embodiment, various possible accessories are attached, but the mounting bracket protrusion 7 may be omitted and the horizontal load on the cap 5 is applied to the reinforcing column 2 via the upper part of the hollow column 1. .
中空柱1内面のネジ嵌合溝4又は、そのために設けた突
条が補強柱5表面に線接触して荷重を伝達する。The screw fitting groove 4 on the inner surface of the hollow column 1 or the protrusion provided therefor comes into line contact with the surface of the reinforcing column 5 to transmit the load.
そして、そのまま使用しても前述の理由で、電食を起こ
すおそれはない。Even if it is used as it is, there is no risk of electrolytic corrosion for the reasons mentioned above.
第4図は笠木5が背板、腹板に分離したものの場合を示
す。FIG. 4 shows a case where the Kasagi 5 is separated into a back plate and a belly plate.
中空柱1に取付けた笠木取付金具6の上に腹板5aだけ
を当ててネジ止め後、背板5をはめるのである。Only the belly plate 5a is placed on top of the Kasagi mounting bracket 6 attached to the hollow column 1, and after screwing, the back plate 5 is fitted.
第5,6図は同じく背板5、腹板5aに分離した笠木の
場合であるが、取付金具6をくさび式のものにした例で
ある。Figures 5 and 6 show a case where the cap is separated into a back plate 5 and a belly plate 5a, but the mounting bracket 6 is of a wedge type.
周知の一対の1形材5 a 、5 aをくさび6bによ
り、第6図に示すように中空柱1上端に固定する。A pair of well-known sections 5a, 5a are fixed to the upper end of the hollow column 1 by a wedge 6b, as shown in FIG.
くさび6bの下部が突出部7になり補強柱2上端に入込
んでいる。The lower part of the wedge 6b becomes a protrusion 7 and enters the upper end of the reinforcing column 2.
この場合は第1,3図の場合のようなネジ嵌合溝4がな
いがら絶縁間隙3を小さくできる利点もある。In this case, there is an advantage that the insulation gap 3 can be made smaller even though there is no screw fitting groove 4 as in the case of FIGS. 1 and 3.
以上、小数の実施例によって説明したが、この考案は設
計条件により、設計者の公知技術により多様に変化し得
るもので、中空柱は角柱に限らず、補強柱も丸管、丸棒
、工形、コ形鋼等から適宜選択できる。Although the above has been explained using a small number of examples, this invention can be varied in various ways depending on the design conditions and the well-known techniques of the designer. It can be selected as appropriate from the shape, U-shaped steel, etc.
絶縁性間隔片、締付ボルトの使い方、固定する二個所の
位置等は設計者の公知技術に任せられる。The use of the insulating spacer, the tightening bolts, the positions of the two fixing points, etc. are left to the well-known skill of the designer.
この考案はアルミ合金等、不銹金属製手摺柵の支柱にそ
の内面に面接触しないよう鋼柱を入れ、絶縁性間隔片を
介して二個所で固定したから、そのまま現場の取付位置
に立てて下端をアンカープレート、鉄筋等に溶接固定し
、コンクリート打ちができる。This idea involves inserting steel columns into the posts of a handrail fence made of rust-free metal such as aluminum alloy so that they do not come into contact with the inner surface, and fixing them at two points via insulating spacing pieces. The lower end can be welded and fixed to an anchor plate, reinforcing steel, etc. and concrete can be poured.
これは従来のアルミ合金支柱では考えられなかった利便
である。This is a convenience that could not have been considered with conventional aluminum alloy columns.
内外の柱を二個所で個定する上下の締付ボルトも、上記
実施例のようにコンクリ−I・に埋設する位置と、下枠
8取付位置に設けられるから、全く外部へ出ない。The upper and lower tightening bolts that separate the inner and outer columns at two locations are also provided at the location where they are buried in the concrete I and at the location where the lower frame 8 is attached, as in the above embodiment, so that they do not come out to the outside at all.
また外部へボルト頭、ナツトが露出しても、支障のない
位置を選ぶこともできる。You can also choose a position where there is no problem even if the bolt head or nut is exposed to the outside.
電食を防ぐ内外柱間の絶縁手段は最も安価な空気層とし
、補強柱は特別の防錆処理不要である事、中空柱は薄肉
でする事等からこの考案の経済的利点も大きい。The economic advantage of this idea is that the insulation between the inner and outer columns to prevent electrolytic corrosion is the least expensive air layer, the reinforcing columns do not require special anti-rust treatment, and the hollow columns are thin.
しかし最も重要な効果は、強度面で鋼製のものより劣る
とされたアルミ合金手摺柵も、この考案により、その美
麗な外観を損うことなく充分強化でき、特に高層建築用
手摺柵としてその安全性が画期的に高められた事である
。However, the most important effect is that aluminum alloy handrail fences, which are considered to be inferior to steel ones in terms of strength, can be sufficiently strengthened with this invention without compromising their beautiful appearance, making them particularly useful as handrail fences for high-rise buildings. This is a revolutionary improvement in safety.
