本発明は、鉄骨造諮よび鉄骨鉄筋コンクリート造の建築
物または構築物に使用される角鋼管柱の柱脚に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a column base of a square steel pipe column used in a steel frame construction or a steel reinforced concrete building or structure.
従来の技術
鉄骨造建物または構築物の柱として角鋼管が使われるこ
とが多く、耐震上の必要から剛構造とするために鉄骨柱
脚を鉄筋コンクリートで根巻きすることになり、第1図
のような設計が一般に行われている。Conventional technology Square steel pipes are often used as columns in steel-framed buildings or structures, and in order to create a rigid structure due to the need for earthquake resistance, the steel column bases are wrapped with reinforced concrete. design is commonly used.
また鉄骨鉄筋コンクリート造の柱脚部も同様の納まりと
なる。The base of the steel-framed reinforced concrete column will also fit in the same way.
ただしこの方式には次のような数々の問題点がある。However, this method has a number of problems as follows.
発明が解決しようとする問題点

ンカーボルトJの頭部ヲ設置せざるを得なくなり1次の
ような多くの欠点が生ずる。Problems to be Solved by the Invention @1 As shown in Figure 1, the base plate J of the conventional square steel pipe column/ is square or rectangular, but the dimension from the outer surface of the square steel pipe column/ to the outer surface of the neck-wrapping concrete 7, In other words, the concrete cover thickness λ is normally /koj− to /jOtx
Since it is only about M, in order to fix the column, I have no choice but to cut out the square steel pipe column base as shown in the diagram and install the head of the anchor bolt J at the position where the column base is cut. A number of drawbacks arise, such as first order.
(1) 角鋼管柱柱脚の四面に切り火きを作るには、
柱を回転させる必要があって多くの加工手間がかかり、
しかも柱脚に断面欠損が生じるのでその分だけ柱耐カが
弱くなる。(1) To make bonfires on all four sides of the square steel pipe column base,
It is necessary to rotate the pillar, which takes a lot of processing time,
Moreover, since a cross-sectional defect occurs in the column base, the strength of the column becomes weaker by that amount.
(2)特に角鋼管柱下端とベースプレートを溶接する場
合に、連続溶接ができず、しかも切り欠き縁端部の回わ
し溶接は一實に施工できないので忘れられるおそれさえ
ある。(2) Particularly when welding the lower end of a square steel pipe column and a base plate, continuous welding is not possible, and furthermore, the round welding of the notch edge cannot be performed all at once, so there is a risk that it may be forgotten.
(3) ペースプレートは柱面から60曙程貨出るの

008程度しか残らず、その間に主筋lとフープjを配
筋すれば、鉄筋に対するコンクリートの必要なかぶり厚
(通常ゲθ■以上)を確保するのが困難である。(3) Since the pace plate protrudes from the column surface by about 60 degrees, the dimension from the edge of the base plate to the outer surface of the column concrete is 7j to 7, which is calculated by subtracting jθ- from the above λ.
If only about 0.08 mm remain and the main reinforcement l and hoop j are placed between them, it will be difficult to secure the necessary cover thickness of concrete for the reinforcing bars (normally more than ge θ■).
(4)鉄骨柱建方時に立上り主¥Egが邪魔になるので

不足する上に。(4) The upright main Eg will get in the way when erecting the steel column, so bend it as shown in the dotted line in Figure J and tighten the nut of the steel frame erecting anchor bolt (to turn a spanner or wrench,
The adjacent main reinforcements need to be bent close to 0), and then the main reinforcements are repositioned, but once the main reinforcements have been bent significantly, they will not straighten out as shown in Figure @j, so the cover thickness will become increasingly insufficient. To.
構造上も最も曲げ応力の大きい柱脚断面に於いて主筋が
引張りに効かなくなり、信大な欠陥を残すことになる。Structurally, the main reinforcing bars become ineffective in tension at the section of the column base where the bending stress is greatest, leaving a huge defect.
(5) アンカーボルトのす゛ソトも、主筋の内側で
しかも切り欠きデの間の狭い個所での施工で1作業がし
に<<、よく締まらない恐れがある。(5) There is a risk that the anchor bolts may not tighten properly during one operation if they are installed inside the main reinforcement and in a narrow space between the notches.
(6) 柱脚切り火き2の孔より打検コンク11−ト

発明の効果 本発明による時は。Effect of the invention According to the present invention.
(1) 角屑管柱注脚にリリ欠きを設けないので。(1) There is no rim notch in the foot of the square scrap tube column.

る。In addition to requiring less time and effort for steel frame processing, there is no reduction in yield strength due to loss of the cross section of the foot, and there is no separation of cast concrete due to cement paste flowing into the square steel pipe from the notched hole.
(2) 魚屑管柱下端とペースプレートJとの溶接は
、全周溶接を連続して行えるので、完全な溶接を短時間
で施工できる。(2) Since welding between the lower end of the fish waste pipe column and the pace plate J can be performed continuously over the entire circumference, complete welding can be performed in a short time.
(3)主筋を柱の四隅に寄せることによって。(3) By placing the main reinforcement near the four corners of the column.
主筋lとペースプレートコとのあきが第1〜WgJ図の
ように大きくとれるので、主筋を曲げずに鉄骨柱の建方
ができる。Since the gap between the main reinforcement l and the pace plate can be made large as shown in Figures 1 to WgJ, the steel column can be erected without bending the main reinforcement.
(4) アンカーボルトJの位置が角鋼管柱/の外側
で、主筋lとも離れているのでスパナまたはレンチの4
操作がし易く、ナツトが十分締められる。(4) Since the anchor bolt J is located on the outside of the square steel pipe column and is away from the main reinforcement l, use a spanner or wrench.
It is easy to operate and the nut can be tightened sufficiently.
+51 鉄筋に対するコンクリートのかぶり厚さが確
保できる。+51 The concrete cover thickness over the reinforcing bars can be ensured.
(6) 工費、工期的にも、角鋼管の切り欠きゃ。(6) In terms of construction cost and construction period, cutting out square steel pipes is a problem.
主筋の台直しなどの無理な作業6iなくなるだけ合理化
される。The process is streamlined to the extent that it eliminates difficult tasks such as resetting the main reinforcement.
等、数々の利点が挙げられる。その中でも特に最も重要
な点は、従来設計の柱脚では実現できなかった
(イ)構造上欠陥となる主務の台直しの排除。There are many advantages such as: Among these, the most important point is (a) the elimination of the need to re-stand, which would be a structural defect, which could not be achieved with conventionally designed column bases.
(ロ)鉄筋のかぶ厚さの確保。(b) Ensuring the cover thickness of reinforcing bars.
(ハ) アンカーボルトのナツト締め什けのシ易さと確
実性。(c) Ease and reliability of tightening anchor bolt nuts.
