Description

本発明は、スチールラック及びスチールラック用ビームの改良に関するものである。   The present invention relates to an improvement in a steel rack and a beam for a steel rack.

一般に、スチールラックは、家庭内の書架や商店の商品の載置台として使用される軽荷重用のものから、倉庫で機械部品の保管や収納用の重荷重用のものまで、広く使用されており、棚板やこれを支持するビームも用途に合わせて、例えば軽荷重用、中荷重用、重荷重用と、複数のランクがあり、これをその目的や用途に合わせて使用するようにしている。
そしてかかるスチールラックの構造は、例えば特許文献1及び特許文献2に示すように、断面がL形のアングル支柱若しくは、断面が角形の支柱を四隅に設けこの支柱間に保形を兼ねた棚載せ用のビーム(梁)を設け、このビームに棚板を設置した構造になっている。
In general, steel racks are widely used from light load used as a home for bookshelves and merchandise in stores to heavy load for storing and storing machine parts in warehouses. There are a plurality of ranks for the shelf board and the beam supporting it, for example, for light load, medium load, and heavy load, and these are used in accordance with the purpose and application.
The structure of such a steel rack is, for example, as shown in Patent Document 1 and Patent Document 2, an angle column having an L-shaped section, or a shelf mounted with square-shaped columns having cross sections at four corners and also serving as a shape-retaining member between the columns. For this purpose, a beam is provided and a shelf is installed on the beam.

ところが、従来のスチールラックでは、上記のように複数のランク毎に支柱、ビーム、棚板等、多品種の部材を保管・管理しなくてはならず手間がかかり、広い収納スペースも必要とするという問題があった。
さらに、スチールラックの上記軽荷重用、中荷重用、重荷重用等の各ランクは、安全率は設定されているものの、大まかな目安であって、その許容荷重範囲内で使用する場合でも、例えば収納若しくは載置される物品が棚板上に偏って置かれ、局部的に荷重が偏った場合には当該部分の棚板やこれを支持するビームが変形し、耐久性が悪くなるだけでなく、スチールラック自体が変形、損壊してしまうという危険性もあった。
However, in the conventional steel rack, as described above, it is necessary to store and manage various kinds of members such as columns, beams, shelves, etc. for each rank, and it takes time and requires a large storage space. There was a problem.
Furthermore, each rank of the steel rack for light load, medium load, heavy load, etc. is a rough guideline, although the safety factor is set, and even when used within the allowable load range, for example, When an article to be stored or placed is placed on a shelf board in a biased manner and the load is locally biased, the shelf board in that part or the beam that supports it will be deformed, resulting in poor durability. There was also a risk that the steel rack itself would be deformed and damaged.

Or having a mounting portion fixed by a fixing tool, and the cross-sectional shape of the beam between the mounting portions is from the groove portion into which the edge portion of the shelf plate is inserted and from one side edge forming the groove portion, from the shelf plate Since the load receiving portion that receives the load of the shape is formed to extend substantially horizontally, a large load is received on the wide surface of the load receiving portion that extends from the groove and one side edge that forms the groove. Can do.

これにより、許容荷重範囲を広くして、軽荷重用、中荷重用、重荷重用等の種類を少なくすることができ、従来のように複数のランク毎に支柱、ビーム、棚板等、多品種の部材を保管・管理する手間を少なくできるとともに、その収納スペースも少なくできる利点がある。   This makes it possible to widen the allowable load range and reduce the types for light loads, medium loads, heavy loads, etc. There is an advantage that it is possible to reduce the trouble of storing and managing the members, and to reduce the storage space.

また、本発明はかかるスチールラックは、支柱間に渡ってスチールラック用ビームが梁わたされ、このスチールラック用ビームに天板若しくは棚板を設置されて構成されるスチールラックであって、スチールラック用ビームが、両端部に支柱に掛止され若しくは固定具で固定される取り付け部を有し、当該取り付け部間のビームの断面形状が、棚板の端縁部分が挿入される溝部と当該溝部を形成する一側縁から棚の荷重を受ける荷重受け部を略水平に延出した形状に形成されているので、上述のように大きな荷重や偏荷重にもスチールラック用ビームの変形が無く、安全で且つ、スチールラックの耐久性を大幅に向上させることができる利点がある。   Further, the present invention is a steel rack in which a beam for a steel rack is passed between struts, and a top plate or a shelf is installed on the beam for the steel rack. The beam for use has a mounting part that is hooked to a support column or fixed by a fixture at both ends, and the cross-sectional shape of the beam between the mounting parts is a groove part into which the edge part of the shelf is inserted and the groove part. Since the load receiving part that receives the load of the shelf from one side edge forming the shape is formed in a substantially horizontal shape, there is no deformation of the beam for the steel rack even for a large load or uneven load as described above, There is an advantage that it is safe and the durability of the steel rack can be greatly improved.

以下、本発明にかかるスチールラック用ビームとこれを備えたスチールラックの最も好ましい実施の形態を図面に基づいて説明する。
図1は本発明にかかるスチールラックの分解斜視図であって、図中符号1は後述する部品からなるスチールラックを全体的に示す。
Hereinafter, the most preferred embodiment of a beam for a steel rack according to the present invention and a steel rack provided with the beam will be described with reference to the drawings.
FIG. 1 is an exploded perspective view of a steel rack according to the present invention. In FIG. 1, reference numeral 1 generally indicates a steel rack composed of parts to be described later.

このスチールラック1は、棚板2の4隅に位置して立設される支柱3・3・3・3と、当該支柱3・3・3・3間に配設されるスチールラック用ビーム(以下単にビームという)4・4・4・4・・・と、前記4本の支柱3・3・3・3をビーム4・4・4・4・・・で連結して形成された枠体の上端部に設置される天板5と、枠体の下方に設けられ、棚板2を兼用する底板6とを備えてなる。   This steel rack 1 is composed of columns 3, 3, 3, 3 that are erected at the four corners of a shelf plate 2, and a beam for a steel rack (between the columns 3, 3, 3, 3). (Hereinafter simply referred to as a beam) and a frame formed by connecting the four columns 3, 3, 3, 3 with beams 4, 4, 4, 4,. The top plate 5 installed at the upper end of the base plate and the bottom plate 6 provided below the frame and also serving as the shelf 2 are provided.

上記棚板2は矩形の鋼板を、その周縁を下方に折り曲げて後述のビーム4・4・4・4の溝部13に掛合する掛合辺(端縁部分)7を形成するとともに、下面の中央部分にはその長手方向に鋼板を折り曲げて形成した補強用桟材8が設けられている。
また、上記各支柱3は、鋼板を、その横断面をL形若しくはコの字形あるいはロの字形に折り曲げて形成されており、側面部分にはビーム4の端部が掛合乃至連結される複数の連結穴9が等間隔に穿設されている。
The shelf plate 2 is a rectangular steel plate and its peripheral edge is bent downward to form an engaging side (edge portion) 7 that engages with a groove 13 of a beam 4, 4, 4, 4, which will be described later. Are provided with reinforcing bars 8 formed by bending a steel plate in the longitudinal direction.
Each of the support columns 3 is formed by bending a steel plate into an L shape, a U shape, or a B shape, and a plurality of side portions are connected to or connected to the end of the beam 4. Connecting holes 9 are formed at equal intervals.

ビーム4は、図2に示すように、両端部分に上記支柱4の連結穴9に掛合乃至連結される掛止部10とボルト等の固定具(図示せず)が挿通される連結具挿通孔11とからなる取り付け部12が形成されるとともに、支柱3・3間部分は、その縦断面の形状が、棚板2の掛合辺7が挿入される溝部13と、この溝部13を形成する一側縁から棚板2の荷重を受ける荷重受け部14を略水平に延出した形状に、鋼板を折り曲げてしてある。
因みに、溝部13を形成する他縁部分は、溝部13の内方に折り曲げてビーム4の補強を兼ねた端部処理15が施されている。
As shown in FIG. 2, the beam 4 has a coupling tool insertion hole through which a hook 10 and a fixing tool (not shown) such as a bolt are inserted at both end portions thereof. 11 is formed, and the portion between the columns 3 and 3 has a vertical cross-sectional shape that forms the groove 13 into which the engaging side 7 of the shelf 2 is inserted, and the groove 13. The steel plate is bent into a shape in which the load receiving portion 14 that receives the load of the shelf board 2 from the side edge extends substantially horizontally.
Incidentally, the other edge part which forms the groove part 13 is bend | folded inward of the groove part 13, and the edge part process 15 which served as reinforcement of the beam 4 is given.

上記のように形成された各部材でスチールラック1を組み立てる場合を次に説明すると、先ず、4本の各支柱3の側面に穿設された連結穴9にビーム4の端部の取り付け部12の掛止部10を掛合させ、連結具挿通孔11にボルト等の固定具を挿通して固定することにより、上下3段のビーム4で4本の支柱3・3・3・3が固定された枠体を形成する。   Next, the case where the steel rack 1 is assembled with each member formed as described above will be described. First, the attachment portion 12 at the end of the beam 4 is inserted into the connection hole 9 formed in the side surface of each of the four columns 3. The four support pillars 3, 3, 3 are fixed by the upper and lower three-stage beams 4 by engaging the latching portions 10 and inserting the fixtures such as bolts into the connector insertion holes 11. A frame is formed.

次に、枠体のビーム4の底部には、棚板2を兼用する底板6を、中断には棚板を、上段には天板5のそれぞれを、図3に示すように、掛合辺7がビーム4の溝部13に掛合するように嵌合させるとともに、各板2・5・6の底面部分16を溝部13の一側縁から略水平に延出した荷重受け部14に当接させると、上下2段のスチールラック1が形成される。
斯くして組み立てられたスチールラック1は、例えば中断部分の棚板2に重い物品を載置した場合、この物品の荷重は棚板2の底面16に面で当接している広い面に分散して受けられるので、単位面積当たりの荷重が小さくなる。
Next, a bottom plate 6 that also serves as the shelf 2 is provided at the bottom of the beam 4 of the frame body, a shelf plate is provided for interruption, and a top plate 5 is provided for the upper stage, as shown in FIG. Is engaged with the groove portion 13 of the beam 4 and the bottom surface portion 16 of each plate 2, 5, 6 is brought into contact with the load receiving portion 14 extending substantially horizontally from one side edge of the groove portion 13. The upper and lower steel racks 1 are formed.
In the steel rack 1 thus assembled, for example, when a heavy article is placed on the shelf 2 at the interrupted portion, the load of the article is distributed over a wide surface that is in contact with the bottom surface 16 of the shelf 2. Therefore, the load per unit area becomes small.

したがって、重い物品が棚板2に偏った状態で載置されても、ビーム4や棚板2の変形を可及的に防止することができる。これにより、棚板2への載置許容範囲を拡大させることができる。
ここで、ビーム4の溝部13の一側縁から保護水平に形成された荷重受け部14について付言しておくと、この荷重受け部14は、単に棚板2からの荷重を受けとめるだけでなく、溝部13の補強を兼ねており、例えば大きな荷重で溝部13が開いて変形するのを防止する。
Therefore, even if a heavy article is placed on the shelf 2 in a biased state, the deformation of the beam 4 and the shelf 2 can be prevented as much as possible. Thereby, the mounting allowable range on the shelf 2 can be expanded.
Here, if it adds about the load receiving part 14 formed in the protection horizontal from the one side edge of the groove part 13 of the beam 4, this load receiving part 14 not only receives the load from the shelf 2, It also serves to reinforce the groove 13 and prevents the groove 13 from being opened and deformed by a large load, for example.

尚、上記実施の形態ではビーム4の溝部13の縦断面の形状を図上角形U字状にしてあるが、こうしたものに限られず、溝部13の縦断面の形状を例えば図4に示すようにV字形にしても良い。
この場合、溝部13に挿入された棚板2の掛合辺7の先端部がV字形の傾斜面21に当接して案内されて落ち着くので、ガタツキを防止することができる。
また、図示は省略したが底が丸いU字形にすることもできることは勿論のことである。
In the above embodiment, the shape of the longitudinal section of the groove 13 of the beam 4 is a square U-shape in the figure. However, the shape is not limited to this, and the shape of the longitudinal section of the groove 13 is, for example, as shown in FIG. It may be V-shaped.
In this case, since the front end portion of the engaging side 7 of the shelf 2 inserted in the groove portion 13 is guided and settled against the V-shaped inclined surface 21, rattling can be prevented.
In addition, although not shown, it is needless to say that a U-shape with a round bottom can be used.
