Description

本発明は、コンクリートやアスファルト等の骨材ストックヤードの施工法に関するものである。 The present invention relates to a construction method for aggregate stockyards for concrete, asphalt, etc.

道路舗装工事では、工事規模がかなりのものになると舗装材料としてのアスファルトを製造するための製造プラントや骨材ストックヤードを仮設的に設けることがある。 When road paving work is of a considerable scale, temporary manufacturing plants and aggregate stock yards for producing asphalt, the paving material, may be set up.

そして、この骨材ストックヤードは砂利、砂等の骨材を種類ごとに野積みできるものとして、間隔を存してフェンスを並列させてなるものである。 This aggregate stockyard consists of fences lined up at intervals, allowing aggregates such as gravel and sand to be piled up by type.

並列するフェンス間が骨材のストック場所であり、当該フェンスの前後が材料の搬入、搬出口となる。 The area between the parallel fences is where aggregates are stored, and the areas in front of and behind the fences are where materials are brought in and taken out.

出願人は先に設置の施工が簡単で、しかも各フェンスは骨材の荷重に十分に耐え得る強度を有し、また、撤去も簡単で、しかも撤去に際して産業廃棄物の発生も生じない骨材ストックヤードとして下記の特許文献のものを提案し、特許を取得した。 The applicant previously proposed and obtained a patent for an aggregate stockyard described in the patent document below, which is easy to install, each fence is strong enough to withstand the weight of aggregate, and is easy to remove without generating industrial waste upon removal.

特許第2537730号明細書Patent No. 2537730

これは図9に示すように 間隔を存してフェンス1,1aを並列させてなる骨材ストックヤードにおいて、鋼材による脚体5を直交方向に向けて設けた鋼材による支柱3を該脚体5が相互に平行になるようにして適宜間隔で立設し、この支柱3の側面に板体としてのコルゲートシート4を張設してフェンス1として構成する。また、端のフェンス1aを構成する支柱3は脚体5aがストックヤード外側に突出するようにし、該支柱1aの中間から脚体5aの先端にかけて鋼材による斜材6をかけわたすものである。 As shown in Figure 9, in an aggregate stockyard consisting of fences 1, 1a arranged side by side with a gap between them, steel posts 3 with steel legs 5 facing perpendicularly are erected at appropriate intervals so that the legs 5 are parallel to each other, and a corrugated sheet 4 as a plate is stretched on the sides of the posts 3 to form the fence 1. In addition, the posts 3 that make up the end fence 1a have legs 5a that protrude outside the stockyard, and steel diagonal members 6 are stretched from the middle of the posts 1a to the tips of the legs 5a.

端列のフェンス1aを除いて中列のフェンス1は全て同じ形のものである。また、フェンス1の間にスクリニングスの上屋2を設けている。 Except for the fences 1a in the end rows, all of the fences 1 in the middle row are of the same shape. In addition, a screening shed 2 is provided between the fences 1.

このようにして、垂直に立ち上げられた支柱3の側面に波板としてのコルゲートシート4をこのコルゲートシート4の波の山が連続する方向に対して支柱3の長手方向が直交するように張設することで、このコルゲートシート4は適宜間隔で立設する支柱3,3間に掛け渡される。 In this way, the corrugated sheet 4 is stretched over the sides of the vertically erected support posts 3 so that the longitudinal direction of the support posts 3 is perpendicular to the direction in which the crests of the corrugated sheet 4 continue, and the corrugated sheet 4 is stretched across the support posts 3, 3 that are erected at appropriate intervals.

一方、端列のフェンス1aについても、前記中状列のフェンス1と同様に、H型鋼等の鋼材による支柱3aと、この支柱3aとおなじH型鋼等の鋼材による支柱根としての脚体5aと、波板であるコルゲートシート4の組合せからなる。 On the other hand, like the fence 1 in the middle row, the fence 1 in the end row is also made up of a post 3a made of steel such as an H-shaped steel, a leg 5a serving as the post base, also made of the same steel such as an H-shaped steel as the post 3a, and a corrugated sheet 4, which is a corrugated plate.

支柱3の下端に脚体5をフェンス1aに対して直交方向に設け、かつこの支柱3は脚体5の端によせて結合して全体をL字形となるように結合する。さらに、支柱3の中間から脚体5の先端にかけて鋼材による斜材6を掛け渡すことにより、下部をトラス状とした。 A leg 5 is attached to the lower end of the support 3 in a direction perpendicular to the fence 1a, and the support 3 is joined to the end of the leg 5 so that the whole is L-shaped. Furthermore, a steel diagonal member 6 is hung from the middle of the support 3 to the tip of the leg 5, giving the lower part a truss shape.

前記特許文献1の骨材ストックヤードを施工するには、図6~図8に示すように、支柱3をクレーン13で吊降ろして接地し、この支柱3に他のクレーン14でコルゲートシート4を水平状態に吊降ろし、支柱3にこのコルゲートシート4の端を結合した上で、コルゲートシート4をクレーン14で吊ったままで支柱3を吊っていたクレーン13を解除する。 To construct the aggregate stockyard of Patent Document 1, as shown in Figures 6 to 8, the support pillar 3 is lowered by a crane 13 and set on the ground, and the corrugated sheet 4 is lowered horizontally onto the support pillar 3 by another crane 14. The ends of the corrugated sheet 4 are then joined to the support pillar 3, and the crane 13 that was suspending the support pillar 3 is released with the corrugated sheet 4 still suspended by the crane 14.

前記支柱3に並ぶ支柱3を同じクレーン13を用いて吊降ろし、この支柱3を接地してコルゲートシート4の他の端を該支柱3に結合する。 The next support 3 next to the previous support 3 is lowered using the same crane 13, and this support 3 is grounded and the other end of the corrugated sheet 4 is connected to the support 3.

このようにして、垂直に立ち上げられた支柱3の側面に波板としてのコルゲートシート4をこのコルゲートシート4の波の山が連続する方向に対して支柱3aの長手方向が直交するように張設する。このコルゲートシート4は適宜間隔で立設する支柱3,3間に掛け渡される。 In this way, the corrugated sheet 4 is stretched over the sides of the vertically erected support posts 3 so that the longitudinal direction of the support posts 3a is perpendicular to the direction in which the crests of the corrugated sheet 4 continue. The corrugated sheet 4 is stretched across the support posts 3, 3 that are erected at appropriate intervals.

支柱3は自立しないのでクレーン13で吊った状態にしておく必要があり、コルゲートシート4は第2のクレーン14で吊下すことになり、2台のクレーンを必要とした。 The support pillar 3 cannot stand on its own, so it had to be suspended by a crane 13, and the corrugated sheet 4 was suspended by a second crane 14, requiring two cranes.

本発明の目的は前記従来例の不都合を解消し、1台のみのクレーンで施工を可能とし、その結果、工費が低減でき、また、安全性を高めることができる骨材ストックヤードの施工法を提供することにある。 The object of the present invention is to provide a construction method for an aggregate stockyard that eliminates the disadvantages of the above-mentioned conventional examples and allows construction to be carried out with only one crane, thereby reducing construction costs and increasing safety.

前記目的を達成するため請求項1記載の本発明は、支柱間に波板を波の山の連続方向に対して支柱側面の長手方向が直交するようにして掛け渡して構成する骨材ストックヤードにおいて、下端に鋼材による脚体を自立する脚体として設けた鋼材による第1の支柱を第1のクレーンで吊降ろして接地させ、この支柱に対して同じ第1のクレーンで波板を波の山の連続方向に対して支柱側面の長手方向が直交するようにして水平に吊降ろして第1の支柱と波板を結合し、第1の支柱は波板を結合した状態で自立することができ、前記同じ第1のクレーンで第1の支柱に並ぶように第2の支柱を吊り降ろしてこの第2の支柱と前記波板を結合することを要旨とするものである。 In order to achieve the above-mentioned object, the present invention described in claim 1 relates to an aggregate stockyard constructed by hanging corrugated sheets between supports so that the longitudinal direction of the support side is perpendicular to the direction in which the wave crests continue, wherein a first support made of steel having a steel leg at its lower end as a free-standing leg is lowered by a first crane to the ground, and the corrugated sheet is lowered horizontally from this support using the same first crane so that the longitudinal direction of the support side is perpendicular to the direction in which the wave crests continue, thereby connecting the first support to the corrugated sheet, so that the first support can stand on its own with the corrugated sheet connected to it, and the second support is lowered by the same first crane so that it is aligned with the first support, thereby connecting the corrugated sheet to the second support.

請求項1記載の本発明によれば、第1の支柱は下端に鋼材による脚体を自立する脚体として設けたものであり、この第1の支柱をクレーンで吊降ろして接地させたなら、そのクレーンを開放して同じクレーンで波板を波の山の連続方向に対して支柱側面の長手方向が直交するようにして水平に吊降ろして第1の支柱と波板を結合することができる。また、そのクレーンでさらに第1の支柱に並ぶように第2の支柱を吊り降ろしてこの第2の支柱と前記波板を結合することができるので1台のクレーンのみの使用ですむ。 According to the present invention described in claim 1, the first support pillar has a steel leg at the bottom end as a self-supporting leg, and once this first support pillar is lowered by a crane and set on the ground, the crane can be released and the corrugated sheet can be lowered horizontally with the same crane so that the longitudinal direction of the support pillar side is perpendicular to the direction of the succession of wave crests, thereby joining the first support pillar and the corrugated sheet. In addition, the same crane can be used to further lower a second support pillar so that it is aligned with the first support pillar, and this second support pillar and the corrugated sheet can be joined, so only one crane is required.

請求項2記載の本発明は第1の支柱と波板を結合した段階で、波板の下に角材による枕をかませることを要旨とするものである。 The gist of the present invention described in claim 2 is that when the first support and the corrugated sheet are joined, a support made of square timber is placed under the corrugated sheet.

請求項2記載の本発明によれば、第1の支柱と波板を結合した状態のものはそのままでも自立はできるが、波板の下に角材による枕をかませることで波板の水平を保ち、より安定した状態で次の作業に移行できる。 According to the present invention described in claim 2, the first support and the corrugated sheet can stand on their own when connected, but by placing a square piece of wood under the corrugated sheet, the sheet can be kept horizontal, allowing it to be moved to the next work in a more stable state.

請求項3記載の本発明は、第1の支柱の脚体は十字方向に突設し、第2の支柱の脚体は横一文字に突設することを要旨とするものである。 The gist of the present invention described in claim 3 is that the legs of the first support are arranged to protrude in a cross direction, and the legs of the second support are arranged to protrude in a horizontal line.

請求項3記載の本発明によれば、第1の支柱の脚体は自立するものとして十字方向に突設したが、第2の支柱はクレーンで吊降ろしてそのまま波板を結合することができ、第1の支柱と第2の支柱に架け渡される波板で全体が自立するものとなるので、第2の支柱を吊降ろしたクレーンは開放して他の作業に用いるこことができる。 According to the present invention described in claim 3, the legs of the first support are self-supporting and protrude in a cross direction, but the second support can be lowered by a crane and the corrugated sheet can be connected to it as is. Since the entire structure is self-supporting with the corrugated sheet stretched across the first and second support, the crane that lowers the second support can be released and used for other work.

このようにして第2の支柱以下は第1の支柱と比較して脚体が簡易な安価なもので済む。 In this way, the second and subsequent support pillars can have simpler and less expensive legs compared to the first support pillar.

以上述べたように本発明の骨材ストックヤードの施工法は1台のみのクレーンで施工を可能としたので、その結果、重機の使用料等の工費が低減でき、また、複数の重機が錯綜して作業することもないので安全性を高めることができるものである。 As described above, the aggregate stockyard construction method of the present invention allows construction to be completed with only one crane, which results in reduced construction costs, such as the use of heavy machinery, and also increases safety, as there is no need for multiple pieces of heavy machinery to work together.

以下、図面について本発明の実施の形態を詳細に説明する。図1~図3は本発明の骨材ストックヤードの施工法の1実施形態の工程を示す斜視図で、前記従来例を示す図6~図9と同一構成要素には同一参照符号を付したものである。 The following describes in detail an embodiment of the present invention with reference to the drawings. Figures 1 to 3 are perspective views showing the steps of one embodiment of the construction method for an aggregate stockyard of the present invention, and the same components as those in Figures 6 to 9 showing the conventional example are given the same reference numerals.

本発明により施工される骨材ストックヤードの全体から説明すると、図4に示すように、間隔を存してフェンス1を並列させてなるものである。また、フェンス1の間にスクリニングスの上屋2を設けてもよい。 The aggregate stockyard constructed according to the present invention is constructed as a whole by arranging fences 1 in parallel with a gap between them, as shown in Figure 4. A screening shed 2 may also be provided between the fences 1.

フェンス1は、H型鋼等の鋼材による支柱と、この支柱とおなじH型鋼等の鋼材による支柱根としての脚体と、波板であるコルゲートシート4の組合せからなる。 The fence 1 is made up of a combination of posts made of steel such as H-shaped steel, legs serving as the base of the posts made of the same steel such as H-shaped steel, and a corrugated sheet 4, which is a corrugated plate.

前記H型鋼等の鋼材による支柱は第1の支柱3aと第2の支柱3bがあり、ともに支柱根としての脚体を有するが、第1の支柱3aは脚体を後述のように波板を結合した状態で自立する脚体5aとして設けた。 The pillars made of steel such as H-shaped steel include a first pillar 3a and a second pillar 3b, both of which have legs serving as pillar bases, but the leg of the first pillar 3a is provided as a self-supporting leg 5a with a corrugated plate connected thereto as described below .

一例としてこの脚体5aは十字方向に突設したもので、この脚体がフェンス1の連続方向と直交する向きと平行する向きのものになる。 As an example, the leg 5a protrudes in a cross direction, and is oriented parallel to the direction perpendicular to the continuous direction of the fence 1.

一方、第2の支柱3bは脚体5bを横一文字に突設するもので、支柱3bに対して直交方向に設けて逆T字形となるように組み合わせた。この脚体5bがフェンス1の連続方向と直交する向きで相互に平行となるようにして配設することで、前記支柱3bが適宜間隔毎に並列して立設される。 On the other hand, the second support 3b has legs 5b that protrude horizontally and are arranged perpendicular to the support 3b to form an inverted T shape. The legs 5b are arranged parallel to each other and perpendicular to the direction in which the fence 1 continues, so that the support 3b are erected in parallel at appropriate intervals.

このようにして、垂直に立ち上げられた支柱3a,支柱3bの側面に波板としてのコルゲートシート4をこのコルゲートシート4の波の山が連続する方向に対して支柱3の長手方向が直交するように張設することで、このコルゲートシート4は適宜間隔で立設する支柱3a,支柱3b間に掛け渡される。 In this way, the corrugated sheet 4 is stretched over the sides of the vertically erected supports 3a and 3b so that the longitudinal direction of the supports 3 is perpendicular to the direction in which the crests of the corrugated sheet 4 continue, and the corrugated sheet 4 is stretched across the supports 3a and 3b that are erected at an appropriate interval.

次に本発明の施工法について説明する。図1に示すように鋼材による第1の支柱3aを第1のクレーン13で吊降ろして接地させる。該第1の支柱3aは脚体5aにより自立する。 Next, we will explain the construction method of the present invention. As shown in Figure 1, the first support pillar 3a made of steel is lowered by the first crane 13 and placed on the ground. The first support pillar 3a stands on its own by means of the legs 5a.

次に、この第1のクレーン13は開放し、図2に示すように支柱3aに対して同じ第1のクレーン13で波板であるコルゲートシート4を波の山の連続方向に対して支柱3aの側面の長手方向が直交するようにして水平に吊降ろして第1の支柱3aとで波板であるコルゲートシート4を結合する。 Next, the first crane 13 is opened, and as shown in FIG. 2, the corrugated sheet 4, which is a corrugated plate, is lowered horizontally by the same first crane 13 to the support 3a so that the longitudinal direction of the side of the support 3a is perpendicular to the continuous direction of the wave crests, thereby joining the corrugated sheet 4, which is a corrugated plate, to the first support 3a.

第1の支柱3aと波板であるコルゲートシート4を結合した段階で、波板の下に角材18等によるによる枕をかませる。 After the first support 3a and the corrugated sheet 4 are joined, a support made of a square timber 18 or the like is placed under the corrugated sheet.

コルゲートシート4を吊っていた第1のクレーン13を開放し、同じ第1のクレーン13で第1の支柱3aに並ぶように第2の支柱3bを吊り降ろしてこの第2の支柱3bと前記であるコルゲートシート4を結合する。 The first crane 13 that was suspending the corrugated sheet 4 is released, and the second support 3b is lowered by the same first crane 13 so that it is aligned with the first support 3a, and the second support 3b is connected to the corrugated sheet 4.

図示は省略するが、さらに、第2の支柱3bに対してコルゲートシート4を吊降ろして結合し、この第2の支柱3bに並ぶように新たな第2の支柱3bを吊降ろし、コルゲートシート4を結合し、このようして第2の支柱3bを何本か並べ、コルゲートシート4を架け渡してフェンス1を完成させるが、その吊降ろしは第1のクレーン13の1台のみで行うことができる。 Although not shown in the figure, a corrugated sheet 4 is then lowered and connected to the second support 3b, and a new second support 3b is lowered next to this second support 3b and the corrugated sheet 4 is connected to it. In this way, several second supports 3b are lined up, the corrugated sheet 4 is stretched across them, and the fence 1 is completed; this lowering and lifting can be done by just the first crane 13.

フェンス1の間にスクリニングスの上屋2を設ける場合は、上屋2は、H型鋼等の鋼材を連続させてなる2本の平行な基礎梁を地上に配置し、この基礎梁間にH型鋼等の鋼材による柱と梁9による架構を立設し、該架構間を小梁19で連結し、屋根部にはキーストンプレートによる屋根板11を貼り、側面上部にはシート12を貼りめぐらせた。 When a screening shed 2 is installed between the fences 1, the shed 2 is constructed by placing two parallel foundation beams made of continuous steel material such as H-shaped steel on the ground, erecting a framework of columns and beams 9 made of steel material such as H-shaped steel between the foundation beams, connecting the framework with small beams 19, attaching roof panels 11 made of keystone plates to the roof, and attaching sheets 12 to the upper side surfaces.

キーストンプレートによる屋根板11を貼るのに、図4に示すように、パイプによる親綱取付支柱10を設置して、この親綱取付支柱10で親綱15を張りめぐらせて、作業員の安全性を確保する。 To attach the roof panels 11 using keystone plates, pipe-based lifeline attachment posts 10 are installed as shown in Figure 4, and lifelines 15 are stretched around these lifeline attachment posts 10 to ensure the safety of workers.

図中、17は親綱取付支柱13を立設するためのクランプ、16はシート12のホルダーで、シート12はこのホルダー16から引き出し可能なロールであり、コルゲートシート4の上の開口を遮蔽できる。 In the figure, 17 is a clamp for erecting the lifeline mounting post 13, and 16 is a holder for the sheet 12. The sheet 12 is a roll that can be pulled out from this holder 16, and can cover the opening above the corrugated sheet 4.
