Description

本発明は、奥行き方向一対の支柱どうしを連結部材によって連結して成る、ラックの側枠構造体に関するものである。 The present invention relates to a side frame structure for a rack, which is formed by connecting a pair of columns in the depth direction with a connecting member.

ラックの側枠構造体は、棚板や荷支持用フレームなどの、荷を支持するための荷支持用部材の間口方向の両端を支持する部材として使用されるものであり、奥行き方向一対の支柱どうしを連結部材によって連結して成るものが知られている。この種の側枠構造体としては、例えば特許文献１に記載されるように、前記支柱が、互いに対面する内側が開放した横断面形状であって、前記連結部材の端部は、前記支柱の左右両側板部間に挿入された状態で、当該連結部材の端部と前記支柱の左右両側板部とを貫通する締結具により、前記支柱に取り付けられている。 The side frame structure of the rack is used as a member for supporting both ends of a load supporting member for supporting a load, such as a shelf board or a load supporting frame, in the front direction, and a pair of columns in the depth direction. It is known that the members are connected by a connecting member. As a side frame structure of this type, as described in, for example, Patent Document 1, the pillar has a cross-sectional shape in which the inner surfaces facing each other are open, and the end portion of the connecting member has an end portion of the pillar. In a state of being inserted between the left and right side plate portions, it is attached to the support column by a fastener penetrating the end portion of the connecting member and the left and right side plate portions of the support column.

上記のような支柱構造では、奥行き方向一対の支柱どうしを連結する連結部材の取り付けのために、支柱の内側が開放状態のままであって、この開放端部から塵埃などの異物が支柱内に入り込んで付着堆積する恐れがあり、ラックの使用環境によっては、長期間の使用によって支柱内に入り込んで付着堆積した塵埃などの異物が、周囲の環境に悪影響を及ぼす懸念があった。尤も、角パイプ材など、閉断面構造の支柱を使用すれば、前記のような問題点は解消するが、連結部材の取付けには、支柱の外側面に連結部材の端面を溶接する方法や、連結部材の端面に溶接などで固着された取付け板を支柱の外側面にボルトなどで取り付ける方法によらなければならず、大巾なコストアップは免れない。 In the above-mentioned strut structure, the inside of the strut remains open because of the attachment of the connecting member that connects the pair of strut in the depth direction, and foreign matter such as dust enters the strut from the open end. There is a risk that they may get in and adhere to and accumulate, and depending on the environment in which the rack is used, foreign matter such as dust that has entered and accumulated in the support column for a long period of use may adversely affect the surrounding environment. However, if a pillar having a closed cross-section structure, such as a square pipe material, is used, the above-mentioned problems are solved, but to attach the connecting member, a method of welding the end face of the connecting member to the outer surface of the pillar, A mounting plate fixed to the end surface of the connecting member by welding or the like must be attached to the outer surface of the support column with a bolt or the like, which inevitably results in a large cost increase.

本発明は、上記のような従来の問題点を解消することの出来るラックの側枠構造体を提案するものであって、本発明に係るラックの側枠構造体は、後述する実施例との関係を理解し易くするために、当該実施例の説明において使用した参照符号を括弧付きで付して示すと、奥行き方向一対の支柱(3)どうしを連結部材(4,5)によって連結して成るラックの側枠構造体(1)であって、前記支柱(3)が、互いに対面する内側が開放した横断面形状であり、前記連結部材(4,5)の端部が前記支柱(3)の左右両側板部(7a)間に入り込んだ状態で締結具(19)により支柱(3)に取り付けられている、ラックの側枠構造体(1)において、前記支柱(3)の左右両側板部(7a)間に、この支柱(3)の開放端部(7)を塞ぐカバー(8)が取り付けられ、このカバー(8)は、前記連結部材(4,5)が前記支柱(3)の内部に入り込む連結部材入り込み領域(13)以外の領域において、この支柱(3)の左右両側板部(7a)間の開口端を塞ぐカバー本体(9)と、前記連結部材入り込み領域(13)を支柱(3)の内側から囲む凹窪カバー部(10)とで構成されている。 The present invention proposes a rack side frame structure capable of solving the above-mentioned conventional problems, and the rack side frame structure according to the present invention is the same as the embodiment described later. In order to facilitate understanding of the relationship, the reference numerals used in the description of the example are shown in parentheses, and the pair of depth direction columns (3) are connected by the connecting members (4,5). In the rack side frame structure (1), the support columns (3) have a cross-sectional shape in which the inner surfaces facing each other are open, and the ends of the connecting members (4,5) are the support columns (3). ) Of the side frame structure (1) of the rack, which is attached to the column (3) with the fasteners (19) while being inserted between the left and right side plate parts (7a) of the column (7). A cover (8) that closes the open end (7) of the column (3) is attached between the plate portions (7a), and in the cover (8), the connecting member (4,5) is used for the column (3). ) In the region other than the connecting member entering region (13), the cover body (9) for closing the opening end between the left and right side plate portions (7a) of the support column (3) and the connecting member entering region (13). ) Is formed from the inside of the support column (3) and a concave cover portion (10).

上記本発明の構成によれば、従来の開放断面の支柱をそのまま使用し、支柱に対する連結部材の取り付けにも、支柱内に差し込んだ連結部材の端部を横断貫通するボルトナットなどの締結具を使用する、従来の取付け構造をそのまま使用することが出来るものでありながら、支柱の内部空間は、前記カバー本体と凹窪カバー部とからなるカバーによって、支柱の全長にわたって確実に閉じることが出来る。従って、前記カバーを追加するためのコストはかかるが、支柱が開放断面のものである場合に懸念された問題点が完全に払拭され、しかも、支柱を閉断面構造体に代えると共に支柱に対する連結部材の取り付けに溶接を利用する、従来周知の解決手段と比較して、簡単且つ容易に実施することが出来、大巾なコストダウンを図ることが出来る。更に、本発明の構成によれば、支柱どうしを連結する連結部材の端部が支柱内に入り込む場所では、この連結部材の端部を避けるように支柱内部に凹窪カバー部が入り込んでいるが、それ以外の個所、即ち、支柱の全長の大部分では、カバー本体によって、支柱の左右両側板部間の開口端を塞いでいるので、支柱全体として見たとき、塵埃などの異物が入り込める個所は、前記凹窪カバー部内のみとなり、角パイプ材のような閉断面構造の支柱を使用している状況と殆ど変わりない防塵効果が得られる。 According to the configuration of the present invention described above, a conventional support pillar having an open cross section is used as it is, and a fastener such as a bolt and nut that penetrates through the end of the connection member inserted into the support pillar is also used for mounting the connection member to the support pillar. Although the conventional mounting structure used can be used as it is, the inner space of the column can be reliably closed over the entire length of the column by the cover composed of the cover body and the concave cover portion. Therefore, although the cost for adding the cover is high, the problems of concern when the support pillar has an open cross section are completely wiped out, and the support pillar is replaced with a closed cross section structure and a connecting member for the support pillar. Compared with the conventionally known solution means that uses welding for mounting, it can be carried out easily and easily, and a large cost reduction can be achieved. Further, according to the configuration of the present invention, at the place where the end of the connecting member that connects the columns to each other enters the column, the recessed cover portion is inserted inside the column so as to avoid the end of the connecting member. At other points, that is, at most of the entire length of the column, the cover body closes the open ends between the left and right side plate parts of the column, so when viewed as a column as a whole, foreign matter such as dust can enter. Is only in the concave cover portion, and the dustproof effect is almost the same as in the case where a pillar having a closed cross-section structure such as a square pipe material is used.

上記本発明を実施する場合、前記凹窪カバー部(10)は、支柱(3)の左右両側板部(7a)の内側に重なる左右両側板部(11a)と支柱(3)の内部に位置する底板部(11b)とからなる溝形カバー材(11)と、前記カバー本体(9)の端につながる仕切り板部(12)とから構成し、前記仕切り板部(12)が、前記溝形カバー材(11)内に入り込んで、当該溝形カバー材(11)内の支柱長さ方向の端部を塞ぐように構成することが出来る。この構成によれば、前記凹窪カバー部を、支柱の左右両側板部間の開口端側のみが開いた、箱形に構成する場合と比較して、凹窪カバー部の製造が簡単容易になり、本発明を安価に実施することが出来る。この場合、前記支柱(3)の左右両側板部(7a)に、その開放端側縁から左右外向きに張出し板部(7b)が折曲連設されているときは、前記カバー(8)の溝形カバー材(11)には、その左右両側板部(11a)の開放端側縁から、前記支柱(3)側の左右両張出し板部(7b)の外側に重なる張出し板部(11c)を折曲連設しておくのが望ましい。この構成によれば、カバーを支柱内に嵌入させて、カバー側の張出し板部を支柱側の張出し板部の外側に重ねるだけで、支柱に対するカバーの取付け位置が確定することになり、側枠構造体の組み立てが容易になる。 In the case of carrying out the present invention, the recess cover portion (10) is located inside the left and right side plate portions (11a) and the support column (3) overlapping the inside of the left and right side plate portions (7a) of the support column (3). A groove-shaped cover material (11) consisting of a bottom plate portion (11b) and a partition plate portion (12) connected to the end of the cover body (9), wherein the partition plate portion (12) is the groove. It can be configured so as to enter the shaped cover material (11) and close the end portion of the groove shaped cover material (11) in the column length direction. According to this configuration, the concave cover portion can be easily and easily manufactured, as compared with the case where the concave cover portion is formed in a box shape in which only the opening end sides between the left and right side plate portions of the column are opened. Therefore, the present invention can be implemented at low cost. In this case, when the left and right side plate portions (7a) of the support column (3) are bent and connected outwardly from the open end side edge thereof outwardly to the left and right, the cover (8) In the groove-shaped cover material (11), the overhanging plate portion (11c) that overlaps with the outer edges of the left and right side plate portions (11a) on both sides of the left and right overhanging plate portions (7b) on the column (3) side. It is desirable to make a series of bends. According to this configuration, by simply inserting the cover into the column and overlapping the cover-side overhanging plate portion with the outside of the column-side overhanging plate portion, the mounting position of the cover with respect to the column can be determined. Assembling the structure becomes easy.

又、前記凹窪カバー部(10)は、前記連結部材入り込み領域(13)の支柱長さ方向の端部を塞ぐ仕切り板部(12)と、この仕切り板部(12)に連なる底板部(22)とを備え、この凹窪カバー部(10)の左右両側に前記支柱の左右両側板部(7a)が隣接するように構成することが出来る。即ち、凹窪カバー部の一部を、前記支柱の左右両側板部で兼用させて、全体の使用材料を節減することが出来る。この場合、前記支柱(3)が、巾の広い支柱本体部(6)と巾が狭まった開放端部(7)とから構成され、前記凹窪カバー部(10)の深さを深くするために、前記底板部(22)が、支柱(3)の前記支柱本体部(6)内に入り込むようなときは、当該底板部(22)の左右両側辺から、支柱(3)の前記開放端部(7)における左右両側板部(7a)の内側に達する左右両側板部(23)を連設することが出来る。 Further, the concave cover portion (10) is a partition plate portion (12) for closing the end portion of the connecting member entering region (13) in the column length direction, and a bottom plate portion (12) connected to the partition plate portion (12). 22), and the left and right side plate portions (7a) of the support columns can be configured to be adjacent to the left and right sides of the concave cover portion (10) . That is, a part of the recessed cover portion can also be used by both the left and right side plate portions of the support column to save the entire material used. In this case, the column (3) is composed of a column body (6) having a wide width and an open end portion (7) having a narrow width in order to deepen the depth of the concave cover portion (10). In addition, when the bottom plate portion (22) enters into the column main body portion (6) of the column (3), from the left and right sides of the bottom plate portion (22), the open end of the column (3). The left and right side plate portions (23) reaching the inside of the left and right side plate portions (7a) of the portion (7) can be connected in series.

勿論、本発明を実施する場合、前記凹窪カバー部(10)は、支柱(3)の左右両側板部(7a)間に嵌まり込む有底箱形部材で構成することも可能である。この構成によれば、支柱の連結部材入り込み領域での支柱内に対する防塵効果を、簡単且つ確実に高めることが出来る。更に、前記カバー本体と前記凹窪カバー部とからなるカバーを、支柱の全長にわたって連続した１本のカバーとして構成することも可能であるが、当然、前記凹窪カバー部が配置される連結部材入り込み領域は、支柱の長さ方向の複数個所に存在するので、前記カバー本体(9)と前記凹窪カバー部(10)とは、当該凹窪カバー部(10)の支柱長さ方向両端の内の少なくとも一端において分割することが出来る。この構成によれば、長尺の１本のカバーを取り扱わなければならない場合と比較して、支柱への取付けなどの作業が容易に行える。 Of course, when implementing the present invention, the concave cover portion (10) may be formed of a box-shaped member with a bottom fitted between the left and right side plate portions (7a) of the column (3). According to this structure, the dustproof effect in the column in the region where the column is inserted into the connecting member can be easily and surely enhanced. Further, the cover including the cover body and the concave cover portion may be configured as a single continuous cover over the entire length of the column, but naturally, the connecting member in which the concave cover portion is arranged is arranged. Since the intrusion area exists at a plurality of positions in the length direction of the column, the cover main body (9) and the concave recess cover portion (10) are provided at both ends of the concave recess cover portion (10) in the column length direction. Can be split at at least one end of. According to this configuration, as compared with the case where one long cover has to be handled, work such as attachment to a support can be performed easily.

前記カバー８の溝形カバー材１１は、連結部材４，５の端部が取り付けられる支柱３の長さ方向の複数個所、即ち、支柱３の長さ方向複数個所の連結部材入り込み領域１３を支柱３の内部側からカバーするように配置され、カバー本体９は、溝形カバー材１１でカバーされない支柱３の開放端部、即ち、支柱３の開放端部７における左右両側板部７ａ間を閉じるように配置される。従って、カバー本体９、仕切り板部１２、及び溝形カバー材１１の底板部１１ｂが支柱３の長さ方向に連続すると共に、且つ溝形カバー材１１の底板部１１ｂの内側の空間、即ち、連結部材入り込み領域１３の左右両側が、溝形カバー材１１の左右両側板部１１ａで塞がれた状態になる。而して、これらカバー本体９と溝形カバー材１１は、それぞれが備えている左右両側部９ａ及び左右両張出し板部１１ｃを、支柱３の開放端部７における左右両張出し板部７ｂにタッピングビスなどの止着具１４によって止着することにより取り付けることが出来るが、図示のように、溝形カバー材１１の取付けに関しては、その左右両張出し板部１１ｃの端部と、この上に重なるカバー本体９の左右両側部９ａの端部とを、共通の止着具１４により支柱３の左右両張出し板部７ｂに止着することが出来る。 The groove-shaped cover material 11 of the cover 8 has a plurality of connecting member insertion regions 13 at a plurality of positions in the length direction of the supporting column 3 to which the ends of the connecting members 4 and 5 are attached, that is, at a plurality of connecting member insertion regions 13 in the longitudinal direction of the supporting column 3. The cover body 9 is arranged so as to cover from the inner side of the column 3, and the cover body 9 closes the open end of the column 3 that is not covered by the channel-shaped cover material 11, that is, between the left and right side plate portions 7a at the open end 7 of the column 3. Is arranged as. Therefore, the cover main body 9, the partition plate portion 12, and the bottom plate portion 11b of the groove-shaped cover material 11 are continuous in the length direction of the support column 3, and a space inside the bottom plate portion 11b of the groove-shaped cover material 11, that is, The left and right sides of the connecting member entering region 13 are closed by the left and right side plate portions 11 a of the groove-shaped cover material 11. Thus, in the cover body 9 and the groove-shaped cover material 11, the left and right both side portions 9a and the left and right overhanging plate portions 11c provided respectively are tapped to the left and right overhanging plate portions 7b at the open end 7 of the column 3. It can be attached by fixing it with a fixing tool 14 such as a screw, but as shown in the figure, when attaching the channel-shaped cover material 11, the end portions of the left and right projecting plate portions 11c overlap with this. The ends of the left and right side portions 9a of the cover body 9 can be fixed to the left and right overhanging plate portions 7b of the support column 3 by a common fastening device 14.

前記凹窪カバー部１０の溝形カバー材１１が配置される連結部材入り込み領域１３の内、図２及び図３に示すように、支柱３の上下両端に接近して取り付けられる水平連結部材４の端部（斜め連結部材５の端部との交差端部を含む）が入り込む連結部材入り込み領域１３Ａは、支柱３の上下両端に接近しているため、この連結部材入り込み領域１３Ａに配置される凹窪カバー部１０Ａの溝形カバー材１１に対しては、片側にのみカバー本体９を接続することが出来る。この場合には、凹窪カバー部１０Ａの溝形カバー材１１として、その一端が支柱３の端部と一致する長さに構成した溝形カバー材１１を使用することが出来る。勿論、前記連結部材入り込み領域１３Ａが支柱３の端部から離れているときは、当該連結部材入り込み領域１３Ａに配置される溝形カバー材１１と支柱３の端部との間に、仕切り板部１２を備えた、長さの短いカバー本体９を配設することが出来る。何れの場合も、支柱３の内部空間が当該支柱３の上端で開放されるのを防止するために、支柱３の上端には、必要に応じてキャップ１５を被せることが出来る。 As shown in FIGS. 2 and 3, in the connecting member entry region 13 in which the groove-shaped cover material 11 of the concave cover portion 10 is arranged, as shown in FIGS.

The cover body 9 can be connected to only one side of the groove-shaped cover material 11 of the recess cover portion 10A. In this case, as the groove-shaped cover material 11 of the recessed cover portion 10A, it is possible to use the groove-shaped cover material 11 configured such that one end thereof has a length matching the end of the support column 3. Of course, when the connecting member entering region 13A is separated from the end of the support column 3, the partition plate portion is provided between the groove-shaped cover material 11 arranged in the connecting member entering region 13A and the end of the support column 3. A short length cover body 9 with 12 can be arranged. In any case, in order to prevent the internal space of the support column 3 from being opened at the upper end of the support column 3, the upper end of the support column 3 can be covered with a cap 15 if necessary.

尚、水平連結部材４及び斜め連結部材５の両端は、開放端部７が互いに対面する向きで配置された奥行き方向一対の支柱３に連結されるが、この実施例におけるこれら各連結部材４，５は、支柱３における開放端部７の左右両側板部７ａ間の内巾の３／４弱程度の巾を有するもので、下側板部の巾の中央に、この連結部材４，５の巾の１／３強程度の巾のスリット１６が全長にわたって形成された、角形のリップ付きＣ型鋼状のものが使用されている。そしてこれら各連結部材４，５の両端部の上側板部には、その巾の１／３強程度の巾の切込み１７が、端辺から各連結部材４，５の長さ方向に沿って、巾の中央位置に形成されている。従って、水平連結部材４の端部と斜め連結部材５の端部との交差部、及び上下の斜め連結部材５の端部どうしの交差部では、図３及び図４Ｂに示す斜め連結部材５の端部どうしの交差部１８で例示するように、各連結部材４，５のスリット１６と切込み１７とを利用して、各連結部材４，５の端部どうしを互いに噛み合わせて、当該連結部材端部どうしの交差部の全体の巾を、支柱３の開放端部７における左右両側板部７ａ間に、適度の余裕をもって嵌め込める巾としている。具体的には、カバー８の溝形カバー材１１が厚さ0.4mmの薄板材で構成されているとして、支柱３の開放端部７における左右両側板部７ａ間の内巾から、溝形カバー材１１の左右両側板部１１ａの板厚合計の0.8mmを除算した寸法より、前記連結部材端部どうしの交差部の全体の巾を若干狭めている。 Both ends of the horizontal connecting member 4 and the diagonal connecting member 5 are connected to a pair of depth-direction columns 3 in which the open ends 7 are arranged so as to face each other. 5 has a width of about a little less than 3/4 of the inner width between the left and right side plate portions 7a of the open end 7 of the column 3, and the width of the connecting members 4 and 5 is at the center of the width of the lower plate portion. The C-shaped steel with a rectangular lip, in which the slit 16 having a width of about 1/3 of the above is formed over the entire length, is used. And, in the upper side plate portions at both ends of each of the connecting members 4 and 5, a notch 17 having a width of about 1/3 of the width is formed from the end side along the length direction of the connecting members 4 and 5. It is formed at the center of the width. Therefore, at the intersection of the end of the horizontal connecting member 4 and the end of the oblique connecting member 5, and the intersection of the ends of the upper and lower oblique connecting members 5, the diagonal connecting member 5 shown in FIGS. As exemplified by the intersection 18 of the end portions, the slits 16 and the notches 17 of the connecting members 4 and 5 are used to engage the end portions of the connecting members 4 and 5 with each other, and the connecting member is connected. The entire width of the intersection between the end portions is set to be a width that can be fitted between the left and right side plate portions 7a of the open end portion 7 of the support column 3 with an appropriate margin. Specifically, assuming that the groove-shaped cover material 11 of the cover 8 is made of a thin plate material having a thickness of 0.4 mm, the groove-shaped cover material is determined from the inner width between the left and right side plate portions 7a at the open end 7 of the column 3. The width of the entire intersection of the end portions of the connecting member is slightly narrowed by a dimension obtained by dividing 0.8 mm of the total plate thickness of the left and right side plate portions 11a of the material 11.

上記のように、水平連結部材４の単独端部、水平連結部材４の端部と斜め連結部材５の端部との交差部、及び斜め連結部材５の端部どうしの交差部は、支柱３の開放端部７における左右両側板部７ａと、各連結部材４，５の端部を水平に貫通するボルトナットなどの締結具１９により、支柱３の開放端部７における左右両側板部７ａ間に取り付けられるものであるから、支柱３の各連結部材入り込み領域１３，１３Ａの左右両側、即ち、開放端部７における左右両側板部７ａと、凹窪カバー部１０，１０Ａの溝形カバー材１１における左右両側板部１１ａには、図５に示すように、前記締結具１９を挿通させるための貫通孔２０，２１が予め穿設されている。従って、支柱３にカバー８を取り付けるときは、支柱３側の前記貫通孔２０と、溝形カバー材１１側の貫通孔２１とが合致するように、溝形カバー材１１を、支柱３の開放端部７における左右両側板部７ａ間に嵌め込むと共に、上下に隣り合う溝形カバー材１１間で支柱３にカバー本体９を取り付けることにより、各連結部材入り込み領域１３，１３Ａが、溝形カバー材１１と、その内側に嵌合するカバー本体９側の仕切り板部１２とで形成された凹窪カバー部１０，１０Ａによって内側から囲まれた状態で、支柱３の内側の開放端がカバー８で塞がれた状態になる。 As described above, the single end of the horizontal connecting member 4, the intersection of the end of the horizontal connecting member 4 and the end of the diagonal connecting member 5, and the intersection of the end of the diagonal connecting member 5 are the columns 3 Between the left and right side plate parts 7a at the open end 7 of the support column 3 and the left and right side plate parts 7a at the open end part 7 of the support column 3 by means of fasteners 19 such as bolts and nuts that horizontally penetrate the ends of the respective connecting members 4, 5. Since it is attached to each of the connecting members 13 and 13A of the supporting column 3, that is, the left and right side plate portions 7a at the open end 7, and the groove-shaped cover material 11 of the concave cover portions 10 and 10A. As shown in FIG. 5, through holes 20 and 21 for inserting the fasteners 19 are preliminarily formed in the left and right side plate portions 11a. Therefore, when the cover 8 is attached to the pillar 3, the groove-shaped cover material 11 is opened so that the through-hole 20 on the pillar 3 side and the through-hole 21 on the groove-shaped cover material 11 match. By fitting between the left and right side plate portions 7a of the end portion 7 and attaching the cover body 9 to the column 3 between the vertically adjacent groove-shaped cover materials 11, the connecting member insertion regions 13 and 13A are formed into groove-shaped covers. The inner open end of the support column 3 is surrounded by the concave cover portions 10 and 10A formed of the material 11 and the partition plate portion 12 on the cover body 9 side that fits inside the material, and the open end of the support pillar 3 covers the cover 8. Will be blocked.

水平連結部材４の単独端部、又は連結部材の端部どうしの交差部は、対応する位置にある連結部材入り込み領域１３，１３Ａの凹窪カバー部１０，１０Ａ内に嵌め込んだ状態で、支柱３の開放端部７における左右両側板部７ａ間を水平に貫通するボルトナットなどの締結具１９により、支柱３に結合され、側枠構造体１が組み立てられている。尚、連結部材の端部どうしの交差部を支柱３に連結する締結具１９は、十分に締め付けて、連結部材の端部どうしの交差部を支柱３に強固に固定することが出来るが、水平連結部材４の単独端部は、図３に示すように、支柱３に嵌め込まれているカバー８の溝形カバー材１１における左右両側板部１１ａ間の内巾より１／４程度、巾が狭いので、この水平連結部材４の単独端部を支柱３に連結する締結具１９には、当該水平連結部材４の単独端部と溝形カバー材１１の片側の側板部１１ａとの間の隙間を埋めるスペーサーを併用するのが望ましい。 The single end of the horizontal connecting member 4 or the intersection of the end portions of the connecting members is fitted into the recessed cover portions 10 and 10A of the connecting member entering regions 13 and 13A at corresponding positions, and the strut is supported. The side frame structure 1 is assembled by being joined to the support columns 3 by fasteners 19 such as bolts and nuts that horizontally penetrate between the left and right side plate portions 7a at the open end portion 7 of the third frame 3. The fastener 19 that connects the intersection of the ends of the connecting member to the column 3 can be sufficiently tightened to firmly fix the intersection of the ends of the connecting member to the column 3, but As shown in FIG. 3, the single end of the connecting member 4 is narrower by about 1/4 than the inner width between the left and right side plate portions 11a of the groove-shaped cover material 11 of the cover 8 fitted to the support column 3. Therefore, in the fastener 19 that connects the single end of the horizontal connecting member 4 to the column 3, the gap between the single end of the horizontal connecting member 4 and the side plate portion 11a on one side of the groove-shaped cover material 11 is provided. It is desirable to use a filling spacer together.
