Description

本発明は、建物の横架材と接続部材との接続構造及びユニット建物並びにその構築方法に関する。   The present invention relates to a connection structure between a horizontal member of a building and a connection member, a unit building, and a construction method thereof.

下記特許文献1の第二実施形態には、箱型の建物ユニットを隣接して配置した際に、隣り合う天井大梁の捩れ等を矯正した上で連結する技術が開示されている。簡単に説明すると、隣り合う天井大梁の上フランジ間に、送りねじを備えた仮止め用治具を架け渡して上フランジ同士を引き込み、一方又は両方の天井大梁の捩れを矯正する。捩れが矯正された段階で、仮止め用自具を装着したまま、一対の天井大梁の上フランジ間に連結具を架け渡す。そして、最後に仮止め自具を取り外す。
特開平9−105234号公報(段落番号[0056]〜[0073])
In the second embodiment of Patent Document 1 described below, a technique is disclosed in which, when box-type building units are arranged adjacent to each other, the twisted or the like of adjacent ceiling beams are corrected and connected. Briefly, a temporary fixing jig provided with a feed screw is bridged between the upper flanges of adjacent ceiling beams, and the upper flanges are pulled together to correct the twist of one or both ceiling beams. At the stage where the twist is corrected, the connecting tool is bridged between the upper flanges of the pair of ceiling beams while the temporary fixing tool is mounted. Finally, remove the temporary fastener.
JP-A-9-105234 (paragraph numbers [0056] to [0073])

しかしながら、上記先行技術による場合、天井大梁の捩れを矯正することはできても、天井大梁の撓みを強制することはできないという問題がある。具体的に説明すると、ユニット建物を構築する際に、例えば2個の箱型の建物ユニットを平行に配置し、その妻面に隣接して大スパンの箱型の建物ユニットを直交して配置することがある(以下、前者を「平行ユニット」、後者を「直交ユニット」と称す。)。このような建物ユニットの配置を採った場合、直交ユニットの天井大梁の長手方向の中間部と2個の平行ユニットの連結部(2本の柱が並ぶ箇所)とを緊結することになるが、直交ユニットの天井大梁はスパン長が長いため、ある程度の撓みが生じている。この撓みは予め決められた範囲内の撓み量になるように設計されているが、建築地で直交ユニットの天井大梁の撓みを解消する作業をしてから2個の平行ユニットの連結部とを連結作業を行うため、非常に手間がかかり、施工性が低下していた。   However, according to the above prior art, there is a problem that even though the twist of the ceiling beam can be corrected, the bending of the ceiling beam cannot be forced. More specifically, when building a unit building, for example, two box-type building units are arranged in parallel, and a large-span box-type building unit is arranged orthogonally adjacent to the wife face. In some cases (hereinafter, the former is referred to as a “parallel unit” and the latter as an “orthogonal unit”). When adopting such an arrangement of building units, the longitudinal part of the ceiling beam of the orthogonal unit and the connecting part of the two parallel units (where two pillars are lined up) are tightly connected. Since the ceiling beam of the orthogonal unit has a long span length, a certain degree of bending occurs. This bend is designed so that the bend amount is within a predetermined range, but after the work to eliminate the bend of the ceiling beam of the orthogonal unit in the building area, the connecting part of the two parallel units is connected. Since the connection work is performed, it is very time-consuming and the workability is lowered.

柱18は断面形状が方形の鋼管柱によって構成されており、その上端開放部には方形のプレート30が被嵌されて溶接されている。平行ユニット12が妻方向に隣接して配置された直交ユニット14との接合部16においては、2本の柱18が所定の隙間32をあけて対向して配置されており、これら2本の柱18の上端部同士は鋼板製のドッキングプレート(連結部材)34によって相互に連結されている。   The column 18 is constituted by a steel pipe column having a square cross-sectional shape, and a rectangular plate 30 is fitted and welded to the open end of the column 18. In the joint portion 16 with the orthogonal unit 14 in which the parallel unit 12 is disposed adjacent to the wife direction, the two columns 18 are disposed to face each other with a predetermined gap 32 therebetween. The upper end portions of 18 are connected to each other by a steel plate docking plate (connecting member) 34.

The flange (or bracket) 35 and the base portion 34A are fastened by a bolt 36 and a nut 38, so that the adjacent parallel units 12 are connected to each other vertically and horizontally.

なお、床パネル22側も天井パネル20側と同様に構成されており、長短二種類の床大梁40(図2では長辺側の床大梁40のみ図示し、短辺側の床大梁については図示を省略している。)と、複数の床小梁43(図5参照)とを含んで構成された床フレーム42を備えている。   The floor panel 22 side is configured in the same manner as the ceiling panel 20 side, and has two types of long and short floor beams 40 (in FIG. 2, only the long side floor beams 40 are shown, and the short side floor beams are shown). ) And a plurality of floor beams 43 (see FIG. 5).

上記平行ユニット12に隣接して配置された直交ユニット14も、その部材構成については平行ユニット12の場合と同様である。平行ユニット12の妻面44と直交ユニット14の桁面46との接合部16においては、直交ユニット14の長辺側の天井大梁50が平行ユニット12の2本の柱18に対して所定の隙間48をあけて平行に配置されている。なお、この長辺側の天井大梁50のスパン長は、平行ユニット12の短辺側の天井大梁28のスパン長よりも長く、図4のA線矢視部の接合部16に配置された直交ユニット14の場合、隣接する2個の平行ユニット12が備える2本分の妻側の天井大梁28の長さと柱18の幅に、平行ユニット12間の隙間48の間隙寸法を足した長さに設定されている。   The orthogonal unit 14 arranged adjacent to the parallel unit 12 is the same as that of the parallel unit 12 in terms of its member configuration. In the joint portion 16 between the end face 44 of the parallel unit 12 and the girder face 46 of the orthogonal unit 14, the ceiling girder 50 on the long side of the orthogonal unit 14 has a predetermined gap with respect to the two columns 18 of the parallel unit 12. 48 are arranged in parallel. The span length of the long side ceiling girder 50 is longer than the span length of the short side ceiling girder 28 of the parallel unit 12, and is orthogonal to the joint 16 at the portion indicated by the arrow A in FIG. In the case of the unit 14, the length is obtained by adding the length of the gap between the parallel units 12 to the length of the two ceiling-side beams 28 and the width of the pillars 18 of the two adjacent parallel units 12. Is set.

ここで、上述した隣接する2個の平行ユニット12と直交ユニット14とは、平行ユニット12の2本の柱18と直交ユニット14の長辺側の天井大梁50の長手方向の中間部において、支持ブラケット52と接続ブラケット54とを介して相互に接続されており、以下に詳細に説明する。   Here, the two adjacent parallel units 12 and the orthogonal unit 14 described above are supported in the middle portion in the longitudinal direction of the two columns 18 of the parallel unit 12 and the ceiling beam 50 on the long side of the orthogonal unit 14. The bracket 52 and the connection bracket 54 are connected to each other, and will be described in detail below.

図1〜図3に示されるように、平行ユニット12の柱18の上端部の一側面(直交ユニット14と対向する側の側面)には、支持ブラケット52が溶接等の接合手段によって接合されている。なお、この支持ブラケット52の柱18への取付作業は、高い精度を要するので予め工場内で行われる。   As shown in FIGS. 1 to 3, a support bracket 52 is joined to one side surface (side surface facing the orthogonal unit 14) of the upper end of the column 18 of the parallel unit 12 by a joining means such as welding. Yes. Note that the mounting work of the support bracket 52 to the pillar 18 is performed in advance in the factory because high accuracy is required.

図3(A)に示されるように、支持ブラケット52は、構造的には、柱18の側面に密着されて取付座面として機能する矩形平板状の取付部52Aと、この取付部52Aの下部両サイドに直角に取り付けられた側面視で直角三角形状の一対の支持部52Bと、これらの支持部52Bの上端部に架け渡された平面視で矩形平板状の被載置部52Cと、によって構成されている。被載置部52Cは、取付部52Aと一対の支持部52Bとに溶接により剛接合されている。   As shown in FIG. 3A, structurally, the support bracket 52 includes a rectangular flat plate-shaped mounting portion 52A that functions as a mounting seat surface in close contact with the side surface of the column 18, and a lower portion of the mounting portion 52A. By a pair of right-angled triangular support parts 52B attached to both sides at a right angle in a side view, and a rectangular flat plate-like placement part 52C spanned between the upper ends of these support parts 52B, It is configured. The mounted portion 52C is rigidly joined to the mounting portion 52A and the pair of support portions 52B by welding.

一方、直交ユニット14の長手方向の中間部(2本の柱18の上端部と対向する位置)には、一対の接続ブラケット54がボルト62及びナット64等の接合手段によって接合されている。なお、この接続ブラケット54の柱18への取付作業は、建築地で行われるが、支持ブラケット52と同様に予め工場内で取り付けるようにしてもよい。図3(B)に示されるように、接続ブラケット54は、構造的には、支持ブラケット52と全く同一であり、取付部54Aと一対の支持部54Bと載置部54Cとによって構成されている。但し、接続ブラケット54の取付部54Aには、その上縁部及び下縁部にボルト挿通孔56がそれぞれ形成されている。   On the other hand, a pair of connection brackets 54 are joined to a middle portion in the longitudinal direction of the orthogonal unit 14 (position facing the upper ends of the two columns 18) by joining means such as bolts 62 and nuts 64. The attachment work of the connection bracket 54 to the pillar 18 is performed in a building site, but it may be attached in advance in the factory similarly to the support bracket 52. As shown in FIG. 3B, the connection bracket 54 is structurally identical to the support bracket 52, and includes a mounting portion 54A, a pair of support portions 54B, and a placement portion 54C. . However, bolt insertion holes 56 are formed in the upper edge portion and the lower edge portion of the attachment portion 54A of the connection bracket 54, respectively.

なお、上記支持ブラケット52及び接続ブラケット54の接続構造は、図2に示されるように、平行ユニット12の柱18の下端部と直交ユニット14の長辺側の天井大梁50との間でも適用される。また、平行ユニット12の妻面44側の天井大梁28のウェブには、複数箇所にボルト挿通孔58(図5参照)が形成されている。これらのボルト挿通孔58に対応して直交ユニット14の天井大梁50のウェブにも同軸上に図示しないボルト挿通孔が形成されている。そして、これらのボルト挿通孔58を利用して図示しない梁連結ブラケットが取り付けられ、互いに対向して配置される天井大梁28と天井大梁50とがボルト及びナットで緊結されるようになっている。   The connection structure of the support bracket 52 and the connection bracket 54 is also applied between the lower end of the column 18 of the parallel unit 12 and the ceiling beam 50 on the long side of the orthogonal unit 14 as shown in FIG. The In addition, bolt insertion holes 58 (see FIG. 5) are formed at a plurality of locations on the web of the ceiling beam 28 on the side of the end face 44 of the parallel unit 12. Corresponding to these bolt insertion holes 58, bolt insertion holes (not shown) are formed on the same axis on the web of the ceiling beam 50 of the orthogonal unit 14. A beam connecting bracket (not shown) is attached using these bolt insertion holes 58, and the ceiling girder 28 and the ceiling girder 50, which are arranged to face each other, are fastened with bolts and nuts.

(作用・効果)
次に、図5〜図8を用いてユニット建物の構築方法について説明し、その説明を通して本実施形態の作用並びに効果について説明する。
(Action / Effect)
Next, the construction method of a unit building is demonstrated using FIGS. 5-8, and the effect | action and effect of this embodiment are demonstrated through the description.

まず、図4に示されるように、平行ユニット12の妻面44に位置する1本の柱18の屋外側の側面の所定位置に支持ブラケット52が溶接により剛接合される。なお、この作業は予め工場内で行われる。   First, as shown in FIG. 4, the support bracket 52 is rigidly joined to a predetermined position on the side surface on the outdoor side of one column 18 located on the end surface 44 of the parallel unit 12 by welding. This work is performed in advance in the factory.

次に、平行ユニット12及び直交ユニット14が工場から建築地まで輸送され、図6に示されるように、平行ユニット12の方が直交ユニット14よりも先に据え付けられる。平行ユニット12の据付後の状態では、2本の柱18が隣接して配置される接合部16において一対の支持ブラケット52が同一の高さで並んだ状態となる。   Next, the parallel unit 12 and the orthogonal unit 14 are transported from the factory to the building site, and the parallel unit 12 is installed before the orthogonal unit 14 as shown in FIG. In the state after the parallel unit 12 is installed, the pair of support brackets 52 are arranged at the same height in the joint portion 16 where the two pillars 18 are arranged adjacent to each other.

次に、図7に示されるように、直交ユニット14の天井大梁50の長手方向の中間部に一対の接続ブラケット54が取り付けられる。具体的には、天井大梁50のウェブに形成された上下一対のボルト挿通孔60と接続ブラケット54の取付部54Aの上下一対のボルト挿通孔56とを対応させ、ボルト62を天井大梁50のウェブに固着されたウエルドナット64に螺合させることにより、一対の接続ブラケット54が天井大梁50に取り付けられる。なお、この作業は建築地で行われる。   Next, as shown in FIG. 7, a pair of connection brackets 54 is attached to an intermediate portion in the longitudinal direction of the ceiling beam 50 of the orthogonal unit 14. Specifically, the pair of upper and lower bolt insertion holes 60 formed on the web of the ceiling beam 50 and the pair of upper and lower bolt insertion holes 56 of the attachment portion 54A of the connection bracket 54 are made to correspond to each other, and the bolt 62 is connected to the web of the ceiling beam 50. The pair of connection brackets 54 are attached to the ceiling beam 50 by being screwed to the weld nut 64 fixed to the ceiling. This work is performed in the building area.

次に、図8に示されるように、先行して据え付けられた平行ユニット12の妻面44側に隣接するように直交ユニット14が吊り込まれる。このときには、スパン長が長い天井大梁50は、その長手方向の中間部の撓み量が最大になるように撓んでいる。そして、平行ユニット12の一対の支持ブラケット52の被載置部52Cに直交ユニット14の一対の支持ブラケット52の載置部54Cが載置されるように直交ユニット14が吊り降ろされる。これにより、一対の支持ブラケット52に一対の接続ブラケット54が相対的に持ち上げられ、天井大梁50の撓みが解消される。   Next, as shown in FIG. 8, the orthogonal unit 14 is suspended so as to be adjacent to the end face 44 side of the parallel unit 12 installed in advance. At this time, the ceiling girder 50 having a long span length is bent so that the bending amount of the intermediate portion in the longitudinal direction is maximized. Then, the orthogonal unit 14 is suspended so that the placement portions 54C of the pair of support brackets 52 of the orthogonal unit 14 are placed on the placement portions 52C of the pair of support brackets 52 of the parallel unit 12. As a result, the pair of connection brackets 54 is lifted relative to the pair of support brackets 52, and the bending of the ceiling beam 50 is eliminated.

なお、平行ユニット12に対する直交ユニット14の接続作業が終了したら、相互に対向して配置された平行ユニット12の天井大梁28と直交ユニット14の天井大梁50とが前述した梁連結ブラケットを用いて相互に連結される。   When the connection of the orthogonal unit 14 to the parallel unit 12 is completed, the ceiling large beam 28 of the parallel unit 12 and the ceiling large beam 50 of the orthogonal unit 14 that are arranged to face each other are mutually connected using the beam connecting bracket described above. Connected to

このように本実施形態では、一対の平行ユニット12の2本の柱18の上端部(及び下端部)に基準となる支持ブラケット52を配設すると共に、これらの平行ユニット12に対して直交して配置される直交ユニット14の長辺側の天井大梁50の長手方向の中間部に支持ブラケット52に載置されることで撓みを解消する(矯正する)接続ブラケット54を配設したので、直交ユニット14が据え付けられた時点では、平行ユニット12及び直交ユニット14の天井間又は床間に段差が発生しないか、仮に発生したとしても極僅かな段差に抑制される。従って、建築地で段差を解消するための作業(梁同士を連結する際に、ボルトとボルト挿通孔との位置を合わせるため、梁連結ブラケットをハンマーで打撃する等の作業)をする必要がなくなり、建築地での施工性を向上させることができる。なお、天井や床に段差が生じると、クロスを貼る際に段差が表面に現れたり、クロス切れが生じたりする。   As described above, in the present embodiment, the support bracket 52 serving as a reference is disposed at the upper end portions (and the lower end portions) of the two pillars 18 of the pair of parallel units 12 and is orthogonal to the parallel units 12. Since the connecting bracket 54 that eliminates (corrects) the bending by being placed on the support bracket 52 is disposed in the middle portion in the longitudinal direction of the ceiling beam 50 on the long side of the orthogonal unit 14 that is arranged in the At the time when the unit 14 is installed, a step is not generated between the ceilings or floors of the parallel unit 12 and the orthogonal unit 14, or even if it is generated, the step is suppressed to a very small step. Therefore, it is not necessary to perform work for eliminating the level difference in the building site (work such as hitting the beam connecting bracket with a hammer to align the position of the bolt and the bolt insertion hole when connecting the beams). It is possible to improve the workability in the building area. In addition, when a level | step difference arises in a ceiling or a floor, when sticking a cross, a level | step difference will appear on the surface or a cross piece will arise.

この効果を図9及び図10を用いて、以下に説明する。図9には、本実施形態に係る支持ブラケット52及び接続ブラケット54による接続構造を備えていない場合の直交ユニットの長辺側の天井大梁(6モジュール)の撓み量を示すグラフPと、同接続構造を備えている本実施形態の場合の天井大梁50の撓み量を示すグラフQとが対比的に図示されている。なお、グラフQの点Rが支持ブラケット52及び接続ブラケット54による接続点である。上記グラフP、Qとの対比から解るように、本実施形態の接続構造が適用されると、天井大梁50の撓み量は殆ど解消される。   This effect will be described below with reference to FIGS. FIG. 9 is a graph P showing the amount of bending of the long beam on the long side of the orthogonal unit (6 modules) when the connection structure by the support bracket 52 and the connection bracket 54 according to this embodiment is not provided, and the connection. A graph Q showing the amount of deflection of the ceiling girder 50 in the case of this embodiment having a structure is shown in comparison. A point R in the graph Q is a connection point by the support bracket 52 and the connection bracket 54. As understood from the comparison with the graphs P and Q, when the connection structure of this embodiment is applied, the amount of bending of the ceiling beam 50 is almost eliminated.

補足すると、図10(A)にはユニット桁大梁に等分布荷重が作用したと仮定した場合において、1点を緊結した場合の梁の模式図が示されており、図10(B)には同じ仮定で2点を緊結した場合の梁の模式図が示されている。前者に対応する弾性曲線式は数1で現され、後者に対応する弾性曲線式は数2及び数3で現されるが、本実施形態によれば、これらの弾性曲線式を略正確に再現できるものと考えられる。   Supplementally, FIG. 10 (A) shows a schematic diagram of a beam when one point is tightly bound, assuming that an equally distributed load is applied to a unit girder girder, and FIG. 10 (B). A schematic diagram of a beam when two points are connected under the same assumption is shown. The elastic curve equation corresponding to the former is expressed by Equation 1, and the elastic curve equation corresponding to the latter is expressed by Equation 2 and Equation 3. According to the present embodiment, these elastic curve equations are reproduced substantially accurately. It is considered possible.

また、本実施形態では、接続ブラケット54の載置部54Cを支持ブラケット52の被載置部52Cに載置させるだけでよいので、ボルト締結作業や溶接作業等を行う必要がない。従って、建築地での施工作業の効率を向上させることができる。   Moreover, in this embodiment, since only the mounting part 54C of the connection bracket 54 needs to be mounted on the mounting part 52C of the support bracket 52, it is not necessary to perform a bolt fastening operation or a welding operation. Therefore, it is possible to improve the efficiency of construction work in the building area.

さらに、本実施形態では、2個の平行ユニット12と1個の直交ユニット14とが平面視で略Π字形に配置されているので、接合部16に位置する長辺側の天井大梁50に撓みが生じ易い。従って、直交ユニット14の長辺側(桁面46側)の天井大梁50の撓みを効果的に矯正することができる。   Furthermore, in the present embodiment, the two parallel units 12 and the one orthogonal unit 14 are arranged in a substantially square shape in a plan view, so that the long side side ceiling girder 50 positioned at the joint 16 is bent. Is likely to occur. Accordingly, it is possible to effectively correct the bending of the ceiling beam 50 on the long side (the girder face 46 side) of the orthogonal unit 14.

また、本実施形態では、支持ブラケット52については、予め工場内で平行ユニット12の柱18の所定位置に取り付けることとしたので、建築地で支持ブラケット52を各平行ユニット12に取り付ける場合に比し、建築地での作業が減ると共に品質も良くなる。従って、ユニット建物10の生産性及び品質を向上させることができる。   In the present embodiment, the support bracket 52 is attached in advance to a predetermined position of the pillar 18 of the parallel unit 12 in the factory, so that the support bracket 52 is attached to each parallel unit 12 in a building site. The work in the building area is reduced and the quality is improved. Therefore, the productivity and quality of the unit building 10 can be improved.

〔実施形態の補足説明〕
(1)上述した実施形態では、金属製の支持ブラケット52の被載置部52Cに同じく金属製の接続ブラケット54の載置部54Cを直接載置させていたが、これに限らず、図11に示される実施形態のように、被載置部52Cの上面及び載置部54Cの下面の少なくとも一方に、緩衝材としてのブチルテープ70を貼り付けるようにしてもよい。
[Supplementary explanation of the embodiment]
(1) In the above-described embodiment, the placement portion 54C of the metal connection bracket 54 is directly placed on the placement portion 52C of the metal support bracket 52. However, the present invention is not limited to this. As shown in the embodiment, butyl tape 70 as a buffer material may be attached to at least one of the upper surface of the placement portion 52C and the lower surface of the placement portion 54C.

この構成によれば、歩行時や重量衝撃時に、支持ブラケット52の被載置部52Cと載置部54Cとの間に介在されたブチルテープ70が振動・変形に追従することができる。その結果、支持ブラケット52の被載置部52Cと接続ブラケット54の載置部54Cとが擦れることで発生する床鳴り(きしみ音)等の異音の発生を防止又は抑制することができる。   According to this configuration, the butyl tape 70 interposed between the placement portion 52C and the placement portion 54C of the support bracket 52 can follow vibration and deformation during walking or weight impact.

In addition to the cushioning material, a sliding member such as a Teflon (registered trademark) sheet or a bearing may be interposed between the placement portion 52C and the placement portion 54C. In this case, when the mounting portion 54C of the connection bracket 54 moves (slides) relative to the mounting portion 52C of the support bracket 52 during walking or weight impact, abnormal sounds such as floor noise (squeak noise) are generated. Occurrence can be prevented or suppressed.
