【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、立体トラスより大張間架構に構築された建
屋の支持部構造に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a structure of a support portion of a building constructed on a span span rather than a space truss.
一般に、立体トラスより山形状若しくはアーチ形状に構
築された大張間架構の建屋においては、支持部の支持条
件をピン支持とした場合、支持部を支える下部構造体に
大きな水平反力が生ずるため、下部構造体を相当強固な
構造とする必要がある。Generally, in a building with an Owari frame structure that is constructed in a mountain shape or an arch shape rather than a space truss, if the support condition of the support part is pin support, a large horizontal reaction force will be generated in the lower structure supporting the support part. It is necessary to make the lower structure a considerably strong structure.
このため、この水平力を低減するために、大張間架構体
の支持部を水平力の作用方向に移動可能なローラ支持と
することがある。For this reason, in order to reduce this horizontal force, the support portion of the strut strut structure may be a roller support that is movable in the direction in which the horizontal force acts.

ルトを通し、その貫通部分に固定ナットを螺合すること
により構成されている。Conventionally, the supporting part of this type of structure is constructed by reinforced concrete or steel frame structure for the lower structure supporting the strut structure, and a base plate is attached to the upper end of this lower structure. Anchor bolts or bolts are projected, and at the same time, a bearing plate is attached to the bearing portion of the strut frame structure, and a long hole is formed in this bearing plate. It is configured by screwing a fixing nut to the portion.
そして、大張間架構体の支承部が長孔の大きさの範囲内
で横移動することによって、下部構造体に生ずる水平反
力を低減する構成になっている。The supporting portion of the strut structure is laterally moved within the size of the long hole to reduce the horizontal reaction force generated in the lower structure.
しかし、このような構造では、支承部の横移動量は長孔
の内径によって決まるので、横移動量を大きくするには
長孔を大きくする必要があり、これに伴って支承プレー
トも大きくする必要があり、更に支承部を受ける下部構
造体も大きくする必要あるため、支持部全体が大型化
し、きわめて不経済な設計にならざるを得ない等の課題
があった。However, in such a structure, since the lateral movement amount of the bearing is determined by the inner diameter of the long hole, it is necessary to make the long hole large in order to increase the lateral movement amount. In addition, since the lower structure for receiving the supporting portion also needs to be large, the entire supporting portion becomes large in size, and there is a problem that the design is extremely uneconomical.
この考案は、以上の課題を解決するためになされたもの
で、きわめてコンパクトな構造に構成でき、かつ、支承
部の横移動量を可能な限り大きくできるようにした建屋

さ及び方向は鉛直荷重に起因する水平移動量の大きさ及
び方向等を考慮して決められる。The joining hole 7 is an elongated hole elongated in a certain direction, and its length and direction are determined in consideration of the magnitude and direction of the horizontal movement amount due to the vertical load.
脚6,6は真上に開口する断面略溝形状に形成され、ベー
スプレート５の下側に略平行に一体的に溶接固着されて
いる。The legs 6 and 6 are formed in a substantially groove-shaped cross-section that opens right above, and are integrally fixed to the lower side of the base plate 5 by welding.
また、脚６は例えば、図示するように山形鋼の片側フラ
ンジの縁端部にプレートを一体的に溶接固着する等する
ことにより、きわめて簡易な方法によって形成されてい
る。Further, the leg 6 is formed by a very simple method, for example, by integrally welding and fixing a plate to the edge portion of the one side flange of the angle steel as illustrated.
このように構成されたベース金具２は柱又は梁１の上端
に、脚6,6のみをコンクリート中に埋設し、かつ、ベー
スプレート５を柱又は梁１の上端と略面一にした状態に
設置されている。The base metal fitting 2 configured in this way is installed at the upper end of the pillar or beam 1 so that only the legs 6,6 are embedded in concrete and the base plate 5 is substantially flush with the upper end of the pillar or beam 1. Has been done.
そして、脚6,6の底部は柱又は梁１のコンクリート中に
予め埋設された複数本のアンカーボルト8,8に複数個の
固定ナット9,9によって一体的に固定されている。The bottoms of the legs 6 and 6 are integrally fixed to a plurality of anchor bolts 8 and 8 pre-embedded in the concrete of the pillar or beam 1 by a plurality of fixing nuts 9 and 9.

手12を溶接固着することにより構成されている。The support 4 consists of a horizontal plate 10 and a plurality of vertical plates.
11 and 11 are welded and fixed, and the ball joint 12 is welded and fixed onto the vertical plates 11 and 11.
水平プレート10の略中央部と周辺部には複数個の接合孔
13,13がベースプレート５の接合孔7,7に対応して穿設さ
れ、当該接合孔13,13は接合孔7,7と同一方向に細長い長
孔になっている。A plurality of joint holes are formed in the center and the periphery of the horizontal plate 10.
13 and 13 are formed corresponding to the joint holes 7 and 7 of the base plate 5, and the joint holes 13 and 13 are elongated holes in the same direction as the joint holes 7 and 7.
尚、接合孔13の長さ及び方向は鉛直荷重に起因する水平
移動量の大きさ及び方向等を参酌して決められる。The length and direction of the joint hole 13 are determined in consideration of the magnitude and direction of the horizontal movement amount due to the vertical load.
そして、対応する各接合孔13と接合孔７に接合ボルト14
がそれぞれ締着され、当該複数本の接合ボルト14,14に
よってベース金具２と支承体４が接合されている。Then, the connecting bolts 14 are attached to the corresponding connecting holes 13 and the corresponding connecting holes 7.

このような構成において、大張間架構体の支承部は鉛直
荷重に対し、接合孔７の径の範囲で横移動し、かつ、結
合孔13の範囲で横移動することにより鉛直荷重に起因す
る水平反力を下部構造体には伝達させない。In such a structure, the bearing portion of the strut structure is laterally moved in the range of the diameter of the joint hole 7 with respect to the vertical load, and laterally in the range of the coupling hole 13 to cause the vertical load. The horizontal reaction force is not transmitted to the lower structure.
従って、大張間架構体の支承部は接合孔７及び13の各孔
の径が少々小さくともこれらの孔の径の略２倍の範囲で
横移動することができる。Therefore, even if the diameter of each of the joint holes 7 and 13 is slightly small, the support portion of the strut frame structure can be laterally moved within a range of about twice the diameter of these holes.
尚、接合孔７及び13を長孔とせず、ルーズホールとすれ
ば、支承部は何れの方向にも横移動することができるの
で、何れの方向の水平移動に対しても対応できる。If the joint holes 7 and 13 are not long holes but are loose holes, the support portion can move laterally in any direction, so that it can cope with horizontal movement in any direction.
この考案に係る建屋の支持部構造は以上の構成からなる
ので、以下の効果を有する。Since the structure of the supporting portion of the building according to the present invention has the above-mentioned configuration, it has the following effects.

合孔の内径の範囲で横移動するので、ベース金具及び支
承体双方の接合孔を必要以上に大きくしなくとも、支承
部の横移動量を充分に確保することができ、また、大張
間架構体の支持部を小型化できて経済的設計が可能とな
る。Since the support part of the strut frame structure moves laterally within the range of the inner diameter of the joint holes of both the base metal fitting and the support body, it is possible to make the horizontal side of the support part without making the joint holes of both the base metal fitting and the support body larger than necessary. A sufficient amount of movement can be secured, and the supporting portion of the strut frame structure can be downsized, which enables economical design.
また、大張間架構体の支承部はベース金具及び支承体双
方の接合孔の内径の範囲で自由に横移動でき、しかも、
前記ベース金具と支承体との間に滑り部材が介在され、
大張間架構体の支承部は特に抵抗を受けずにスムーズに
水平移動できるので、大張間架構体の支持部に大きな剪
断力が作用することがなく、従って、大張間架構体の支
持部を特に大がかり構造とする必要もない。In addition, the support part of the span structure can freely move laterally within the range of the inner diameter of the joint holes of both the base metal fitting and the support, and
A sliding member is interposed between the base metal fitting and the support,
Since the support portion of the Ootari frame structure can be smoothly moved horizontally without receiving any resistance, a large shearing force does not act on the support portion of the Ootari frame structure. It is not necessary for the part to have a particularly large structure.
