Description

本発明は、複数の斜柱を備えた柱構造、及び、該柱構造を含む構造体の施工方法に関する。   The present invention relates to a column structure including a plurality of oblique columns, and a method for constructing a structure including the column structure.

大屋根等を支持する柱構造として、複数の斜柱を多叉状に接続した柱構造が提案されている（例えば非特許文献１）。このような柱構造は、周囲の見通しを良好にし、景観にすぐれるという利点がある。非特許文献１に記載の柱構造では、複数の斜柱の柱脚をピン支持とするために、球座に支持された球体から、斜柱毎の連結部が突出した鋳鋼ジョイントが用いられている。   As a column structure for supporting a large roof or the like, a column structure in which a plurality of oblique columns are connected in a multi-fork shape has been proposed (for example, Non-Patent Document 1). Such a column structure has an advantage that the surrounding view is good and the scenery is excellent. In the column structure described in Non-Patent Document 1, in order to use pin bases of a plurality of oblique columns, cast steel joints in which connecting portions for each oblique column protrude from a sphere supported by a ball seat are used. Yes.

非特許文献１に記載の柱構造で利用されている鋳鋼ジョイントは、斜柱を一本ずつ連結部に溶接して接合することが必要であり、施工に時間を要する。特に、駅舎の改良工事において上記の柱構造を採用するような場合、電車が運行していない時間帯しか工事ができないので、工期的に問題となる。   The cast steel joint used in the column structure described in Non-Patent Document 1 requires that the oblique columns be welded to the connecting portion one by one, and requires time for construction. In particular, when the above-mentioned pillar structure is adopted in the improvement work of the station building, the work can be performed only during the time zone when the train is not operating, which causes a problem in terms of construction period.

一方、鋳鋼ジョイントに代わる柱脚のピン支持構造として、ピンと軸孔との組み合わせによる支持構造の採用が挙げられるが、現場で柱脚部にピンを挿入する方法をとると、施工性向上の点で斜柱の施工誤差の許容範囲を大きくする方が有利である。しかし、許容範囲を大きくすると、風荷重や地震荷重等の外力が作用した場合に、ピンと軸孔とのクリアランスが大きいため、構造体がガタついて音鳴りがし易くなる。   On the other hand, as a pin support structure for the column base instead of the cast steel joint, a support structure using a combination of a pin and a shaft hole can be used. However, if a method of inserting the pin into the column base at the site is taken, it will improve the workability Therefore, it is advantageous to increase the allowable range of the construction error of the inclined column. However, when the allowable range is increased, the clearance between the pin and the shaft hole is large when an external force such as a wind load or an earthquake load is applied.

本発明の目的は、短期間で精度よく施工できる柱構造、及び、該柱構造を含む構造体の施工方法を提供することにある。   An object of the present invention is to provide a column structure that can be accurately constructed in a short period of time, and a method for constructing a structure including the column structure.

A plate-like support portion having a shaft hole for pin-supporting the column base of the oblique column, the plurality of support portions arranged radially, and the adjacent support portions disposed adjacent to each other. There is provided a column structure characterized by comprising a reinforcing portion that is joined to each of the support portions and that defines an angle between the adjacent support portions.

The structure A is a two-story building, and the column structure 2 is erected on the floor slab 3 of the second floor part. The column structure 2 is connected to an assembly 11 of beam members constituting the large roof 1 and constitutes a part of a column that supports the large roof 1.

＜柱構造＞
柱構造２は、その下部を構成する垂直な柱部材２３と、その上部を構成する複数の鉄骨の斜柱２１と、これらを接続する接続部２２と、を備える。本実施形態の場合、斜柱２１は４本設けられており、柱部材２３から四叉状にこれらが立ち上がっている。しかし、斜柱２１の数はこれに限られず、二叉状、三叉状或いは五叉状にしてもよい。接続部２２は柱部材２３の上部に固定されると共に、複数の斜柱２１の各柱脚が接続されている。なお、本実施形態では、柱部材２３上に接続部２２を固定する構成としたが、柱部材２３を省略し、床スラブ３に接続部２２を直接固定する構成も採用可能である。 <Column structure>
The column structure 2 includes a vertical column member 23 that forms the lower portion thereof, a plurality of oblique steel pillars 21 that form the upper portion thereof, and a connection portion 22 that connects them. In the present embodiment, four oblique columns 21 are provided, and these stand up from the column member 23 in a four-forked shape. However, the number of the oblique columns 21 is not limited to this, and may be two-forked, three-forked or five-forked. The connecting portion 22 is fixed to the upper portion of the column member 23, and each column base of the plurality of oblique columns 21 is connected. In addition, in this embodiment, although the connection part 22 was fixed on the pillar member 23, the structure which abbreviate | omits the pillar member 23 and directly fixes the connection part 22 to the floor slab 3 is also employable.

図２（Ａ）は接続部２２の平面図、（Ｂ）は接続部２２の正面図である。接続部２２は、斜柱毎に設けられた合計４つの支承部２２１と、ベース部２２２と、隣接する支承部２２１間にそれぞれ配置された合計４つの補強部２２３と、を備える。   FIG. 2A is a plan view of the connection portion 22, and FIG. 2B is a front view of the connection portion 22. The connecting portion 22 includes a total of four support portions 221 provided for each oblique column, a base portion 222, and a total of four reinforcing portions 223 respectively disposed between the adjacent support portions 221.

各支承部２２１は一枚の板状をなしており、その厚み方向に貫通した軸孔２２１ａを有している。各支承部２２１は、図２（Ａ)に示すように、平面視で放射状で、かつ、等角度ピッチ（９０度ピッチ）で配置されている。本実施形態の場合、各支承部２２１がその中心部で接合されて十字状をなしているが、その中心部で分離していてもよい。また、各支承部２２１を等角度ピッチで配置したが、不等角度ピッチとすることも可能である。   Each support portion 221 has a single plate shape and has a shaft hole 221a penetrating in the thickness direction. As shown in FIG. 2A, the support portions 221 are arranged in a radial manner and at an equiangular pitch (90-degree pitch). In the case of this embodiment, each support part 221 is joined at its center part to form a cross shape, but may be separated at its center part. Moreover, although each support part 221 was arrange | positioned at equal angle pitch, it is also possible to make it an unequal angle pitch.

図２（Ａ）に示すように斜柱２１の柱脚側端部には一対の板状の連結部２２１が設けられており、各連結部２２１にはその厚み方向に貫通した軸孔２１１ａが形成されている。斜柱２１は、その連結部２２１間に支承部２２１を挿入し、軸孔２２１ａ及び軸孔２１１ａにピン２４を挿通することで接続部２２に接続され、かつ、ピン支持される。   As shown in FIG. 2A, a pair of plate-like connecting portions 221 is provided at the column leg side end of the oblique column 21, and each connecting portion 221 has a shaft hole 211a penetrating in the thickness direction. Is formed. The oblique column 21 is connected to and supported by the connecting portion 22 by inserting the support portion 221 between the connecting portions 221 and inserting the pin 24 through the shaft hole 221a and the shaft hole 211a.

本実施形態の場合、斜柱２１側を一対の板状の連結部２２１とし、接続部２２側を一枚の板状の支承部２２１としたが、斜柱２１側を一枚の板状の連結部とし、接続部２２側を一対の板状の支承部としてもよい。   In the present embodiment, the oblique column 21 side is a pair of plate-like connecting portions 221 and the connection portion 22 side is a single plate-like support portion 221, but the oblique column 21 side is a single plate-like support portion. It is good also as a connection part and it is good also considering a connection part 22 side as a pair of plate-shaped support part.

なお、図２（Ｂ)に示すように斜柱２１の柱頭側端部にも、一対の板状の連結部２２１及び軸孔２１１ａが形成されており、梁部材の組立体１１に設けた連結部１１２にピン支持される。   As shown in FIG. 2 (B), a pair of plate-like connecting portions 221 and a shaft hole 211a are also formed at the stigma-side end portion of the oblique column 21, and the connection provided in the beam member assembly 11 is provided. Pin 112 is supported by part 112.

ベース部２２２は、本実施形態の場合、円板状をなし、各支承部２２１の下面が溶接等によって固着されている。ベース部２２２には、その厚み方向に貫通した取付孔２２２ａが設けられている。図２（Ｂ)に示すように、取付孔２２２ａには柱部材２３の上端部に設けたベースプレート２３１（図１参照）に植設したボルト２３１ａが挿通し、ボルト２３１ａにはナット２３１ｂが螺着される。   In the present embodiment, the base portion 222 has a disk shape, and the lower surface of each support portion 221 is fixed by welding or the like. The base portion 222 is provided with a mounting hole 222a penetrating in the thickness direction. As shown in FIG. 2B, a bolt 231a planted on a base plate 231 (see FIG. 1) provided at the upper end of the column member 23 is inserted into the mounting hole 222a, and a nut 231b is screwed into the bolt 231a. Is done.

取付孔２２２ａはボルト２３１ａの直径よりも十分大きな直径を有しており、ベースプレート２３１に対する接続部２２の水平方向の位置を調整可能としている。更に、ベース部２２２とベースプレート２３１との間に、高さ調整プレートを挟み込むことにより、接続部２２の鉛直方向の位置調整も可能としている。接続部２２はこれらの位置調整ののち、ナット２３１ｂを締結して仮固定し、ベース部２２２とベースプレート２３１とを溶接することで、最終的に固定することができる。   The mounting hole 222a has a diameter sufficiently larger than the diameter of the bolt 231a, and the horizontal position of the connecting portion 22 with respect to the base plate 231 can be adjusted. Further, the height adjustment plate is sandwiched between the base portion 222 and the base plate 231 so that the position of the connection portion 22 in the vertical direction can be adjusted. After these position adjustments, the connecting portion 22 can be finally fixed by fastening and temporarily fixing the nut 231 b and welding the base portion 222 and the base plate 231.

各補強部２２３は、隣接する支承部２２１にそれぞれ接合され、隣接する支承部２２１間の角度を規定している。本実施形態の場合、各補強部２２３は扇型をなしており、その端面間の角度が、支承部２２１の配設ピッチに合わせて９０度となっている。本実施形態では、補強部２２３の形状を扇型としているが、例えば三角形等、他の形状であってもよい。   Each reinforcement part 223 is joined to the adjacent support part 221, respectively, and defines an angle between the adjacent support parts 221. In the case of the present embodiment, each reinforcing portion 223 has a fan shape, and the angle between the end faces is 90 degrees in accordance with the arrangement pitch of the support portions 221. In the present embodiment, the shape of the reinforcing portion 223 is a fan shape, but may be another shape such as a triangle.

補強部２２３を設けたことで、支承部２２１を補強でき、座屈防止を図れる。特に図２（Ｂ)に示すように、各斜柱２１の軸線Ｌの交点Ｐと同じ高さに補強部２２３の位置を設定することにより、支承部２２１の補強効果を高めることができる。   By providing the reinforcement part 223, the support part 221 can be reinforced and buckling prevention can be aimed at. In particular, as shown in FIG. 2B, by setting the position of the reinforcing portion 223 at the same height as the intersection point P of the axis L of each oblique column 21, the reinforcing effect of the support portion 221 can be enhanced.

補強部２２３は、また、支承部２２１の配置精度を向上することができる。図２（Ｃ）は接続部２２の組立例を示す説明図である。同図の例では、４つの支承部２２１を、１つの部材２２１Ａに２つの部材２２１Ｂを溶接すること構成する場合を例示している。部材２２１Ａは２つの支承部２２１を形成し、各部材２２１Ｂは１つの支承部２２１を形成することになる。   The reinforcement part 223 can also improve the placement accuracy of the support part 221. FIG. 2C is an explanatory view showing an assembly example of the connecting portion 22. In the example of the figure, a case where the four support portions 221 are configured by welding two members 221B to one member 221A is illustrated. The member 221 </ b> A forms two support portions 221, and each member 221 </ b> B forms one support portion 221.

部材２２１Ａには部材２２１Ｂが溶接されるが、その際、これらの一方に補強部２２３を溶接しておく。そうすると、補強部２２３を定規（分度器）として利用して、部材間の溶接作業を行える。この結果、支承部２２１の配置精度を向上できる。   The member 221B is welded to the member 221A, and at this time, the reinforcing portion 223 is welded to one of them. Then, the welding work between members can be performed using the reinforcement part 223 as a ruler (protractor). As a result, the placement accuracy of the support portion 221 can be improved.

本実施形態では、このように、接続部２２３を鉄鋼の板材の組合せで構成できるので、その製造コストを抑制できる。また、斜柱２１との接続作業に溶接は不要であり、ピン２４の挿入によるので、施工期間の短縮化を図れる。   In this embodiment, since the connection part 223 can be comprised with the combination of the steel plate material in this way, the manufacturing cost can be suppressed. Further, welding is not necessary for the connection work with the oblique column 21 and the insertion period can be shortened because the pins 24 are inserted.

＜施工方法＞
次に、組立体１と柱構造２との施工方法の例について図３乃至図６を参照して説明する。構造物Ａが駅舎等の建築物である場合には、建て方時間が夜間等に限られる。そこで、本実施形態では、下記に述べるように、組立体１と柱構造２の一部をユニット化しておき、建て方時間を短縮する。また、構造体Ａがガタついて音鳴りすることを抑制するため、施工誤差をより小さくする。上述した補強部２２３の定規（分度器）としての利用による支承部２２１の配置精度と、これから説明する施工方法による施工精度とにより、例えば、軸孔２１１ａ、２２１ａの直径が７０ｍｍの場合に、ピン２４との許容誤差を０．５ｍｍ程度に抑えることができる。 <Construction method>
Next, an example of a construction method of the assembly 1 and the column structure 2 will be described with reference to FIGS. When the structure A is a building such as a station building, the building time is limited to nighttime. Therefore, in this embodiment, as will be described below, a part of the assembly 1 and the column structure 2 is unitized to shorten the building time. Moreover, in order to suppress the structure A from rattling and sounding, the construction error is further reduced. For example, when the diameter of the shaft holes 211a and 221a is 70 mm, the pin 24 is arranged according to the placement accuracy of the support portion 221 by using the reinforcing portion 223 as a ruler (protractor) and the construction accuracy described below. Can be suppressed to about 0.5 mm.

図３（Ａ）を参照して、まず、組立体１をバックヤードで地組みする。組立体１は鉄骨の梁部材１１１を正方形の格子状に組み付けて構成されており、四隅部分には斜柱２１が接続される支承部１１２が設けられる。この段階では組立体１は仮締めされる。   Referring to FIG. 3A, first, the assembly 1 is grounded in the backyard. The assembly 1 is configured by assembling steel beam members 111 in a square lattice shape, and support portions 112 to which the oblique columns 21 are connected are provided at four corners. At this stage, the assembly 1 is temporarily tightened.

次に図３（Ｂ）に示すように、組立体１を不図示のクレーンのクレーンフックＦで吊って、仮置き架台４上にセットする。仮置き架台４はバックヤードで事前に組み立てられる。仮置き架台４はＨ型鋼材や仮設材等から構築され、その上部には組立体１がセットされるジャッキ４１が設けられる。なお、仮置き架台４には転倒防止ワイヤ等が組み付けられると共に枠組足場等が配設されるが、図示を省略している。   Next, as shown in FIG. 3 (B), the assembly 1 is hung by a crane hook F of a crane (not shown) and set on the temporary mounting base 4. The temporary mount 4 is assembled in advance in the backyard. The temporary mounting base 4 is constructed from an H-shaped steel material, a temporary material, or the like, and a jack 41 on which the assembly 1 is set is provided on the upper part. In addition, although the fall prevention wire etc. are assembled | attached to the temporary mounting stand 4 and a frame scaffold etc. are arrange | positioned, illustration is abbreviate | omitted.

When the positioning is completed, the assembly 1 is finally tightened.

組立体１のこれらの作業に並行して、或いは前後して、柱構造２の準備を行う。まず、図４（Ａ)に示すように、複数の斜柱２１のうちの一部の斜柱２１と、接続部２２とを地組みする。同図の例では、同一直線状に位置することになる２本の斜柱２１の柱脚を接続部２２に接続している。次に、図４（Ｂ)に示すように、地組みした２本の斜柱２１と接続部２２とを不図示のクレーンで吊り上げ、仮置き架台４内に配置する。このとき、組立体１の梁部材１１１と斜柱２１とが干渉しないように、地組みした２本の斜柱２１と接続部２２とをＶ字型に吊って降下させる。接続部２２の着地地点には事前にジャッキ５を配置しておく。その後、２本の斜柱２１の一方の柱頭の連結部２１１を組立体１１側の支承部１１２にピン接続する。次に、２本の斜柱２１の他方の柱頭の連結部２１１を組立体１１側の支承部１１２にピン接続する。その際、接続部２２をジャッキ５上に着座させ、ジャッキ５の昇降により連結部２１１と支承部１１２との高さ合わせを行うことができる。   The column structure 2 is prepared in parallel with or before or after these operations of the assembly 1. First, as shown in FIG. 4A, a part of the plurality of oblique columns 21 and the connection portion 22 are assembled. In the example of the figure, the column bases of the two oblique columns 21 that are positioned on the same straight line are connected to the connection portion 22. Next, as shown in FIG. 4 (B), the two assembled oblique columns 21 and the connecting portion 22 are lifted by a crane (not shown) and placed in the temporary mounting base 4. At this time, the two assembled oblique columns 21 and the connecting portion 22 are lowered in a V shape so that the beam member 111 and the oblique column 21 of the assembly 1 do not interfere with each other. The jack 5 is arranged in advance at the landing point of the connecting portion 22. Thereafter, the connecting portion 211 of one stigma of the two oblique columns 21 is pin-connected to the support portion 112 on the assembly 11 side. Next, the connecting portion 211 of the other stigma of the two oblique columns 21 is pin-connected to the support portion 112 on the assembly 11 side. At that time, the connecting portion 22 can be seated on the jack 5, and the height of the connecting portion 211 and the support portion 112 can be adjusted by raising and lowering the jack 5.

次に、残り２本の斜柱２１の接続作業に移る。図５（Ａ)に示すように、残り２本の斜柱２１は一本ずつ不図示のクレーンで吊り上げ、組立体１の梁部材１１１と斜柱２１とが干渉しないように仮置き架台４内に配置する。そして、柱頭の連結部２１１を組立体１１側の支承部１１２にピン接続する。必要に応じてジャッキ５の昇降により連結部２１１と支承部１１２との高さ合わせを行う。残り２本の斜柱２１の接続作業が完了すると、図５（Ｂ)に示すように、４本全部の斜柱２１、接続部２２及び組立体１とが互いに組み付けられ、かつ、構造物Ａに設置されたときの姿勢とされたユニットＵが完成する。ユニットＵには必要に応じて更に小梁等を組み付ける。   Next, the operation of connecting the remaining two oblique columns 21 is started. As shown in FIG. 5A, the remaining two oblique columns 21 are lifted one by one by a crane (not shown), and the beam member 111 of the assembly 1 and the oblique columns 21 are not interfered with each other in the temporary mount 4. To place. Then, the stigma connecting portion 211 is pin-connected to the support portion 112 on the assembly 11 side. If necessary, the height of the connecting portion 211 and the support portion 112 is adjusted by raising and lowering the jack 5. When the connection work of the remaining two oblique columns 21 is completed, as shown in FIG. 5B, all the four oblique columns 21, the connection portion 22, and the assembly 1 are assembled together, and the structure A The unit U in the posture when it is installed in is completed. A small beam or the like is further assembled to the unit U as necessary.

次に、図６に示すように、ユニットＵの建て方を行う。まず、図６（Ａ)に示すように仮置き架台４から、不図示のクレーンによってユニットＵを吊り上げる。次に、図６（Ｂ)に示すように、ユニットＵを床スラブ３に設置した仮置き架台６上にセットする。仮置き架台６の上部にはユニットＵがセットされるジャッキ６１が設けられる。ジャッキ６１の昇降によりユニットＵの高さ方向の位置が調整される。   Next, as shown in FIG. 6, the unit U is built. First, as shown in FIG. 6A, the unit U is lifted from the temporary mount 4 by a crane (not shown). Next, as shown in FIG. 6 (B), the unit U is set on the temporary placing stand 6 installed on the floor slab 3. A jack 61 on which the unit U is set is provided on the upper part of the temporary mounting base 6. The position of the unit U in the height direction is adjusted by raising and lowering the jack 61.

床スラブ３上には柱部材２３が事前に施工されており、柱部材２３のベースプレート２３１上にユニットＵの接続部２２が着座される。ベースプレート２３１と接続部２２との位置決めを行った後、両者が固定される。また、組立体１は、隣接する不図示の組立体１と接続され、溶接にて固定される。こうした施工作業が完了した後、仮置き架台６が撤去される。   A column member 23 is preliminarily constructed on the floor slab 3, and the connecting portion 22 of the unit U is seated on the base plate 231 of the column member 23. After positioning the base plate 231 and the connection part 22, both are fixed. The assembly 1 is connected to an adjacent assembly 1 (not shown) and fixed by welding. After such construction work is completed, the temporary placing stand 6 is removed.

本実施形態では、このようにバックヤードにてユニットＵの組立てを行い、かつ、その位置決めも行っているので、柱構造２やユニットＵを短期間で精度よく施工できる。   In this embodiment, since the unit U is assembled and positioned in the backyard in this way, the column structure 2 and the unit U can be accurately constructed in a short period of time.
