Description

本発明は、道路工事、河川工事、宅地造成工事の土止め擁壁や護岸の構築に使用される壁体構築用ブロックに関するものである。   The present invention relates to a wall construction block used for construction of earth retaining walls and revetments for road construction, river construction, and residential land development construction.

このような壁体構築用ブロックとしては、正面壁板部と背面壁板部を互いに平行に配置し、上下左右の４本の控え梁によって正面壁板部と背面壁板部を一体に連結して、上下に貫通した空洞部を設け、上位側の左右２本の控え梁の後部上面と背面壁板部の上面に跨って第１突起部を幅方向に設け、下位側の左右２本の控え梁の前部下面と正面壁板部の下面に跨って第２突起部を幅方向に設け、上位側の左右２本の控え梁の接合用上面に各２個の第１ピン受孔を設け、下位側の左右２本の控え梁の接合用下面に各２個の第２ピン受孔を設けたものがある（特許文献１参照）。   As such a wall building block, the front wall plate portion and the rear wall plate portion are arranged in parallel to each other, and the front wall plate portion and the rear wall plate portion are integrally connected by four upper, lower, left and right guide beams. The upper and lower cavities are provided, the first protrusions are provided in the width direction across the rear upper surface of the two upper and lower left beams and the upper surface of the rear wall plate, and the lower left and right two A second protrusion is provided in the width direction across the front lower surface of the front beam and the lower surface of the front wall plate, and two first pin receiving holes are provided on the upper surface of the upper and lower two horizontal beams. There are ones in which two second pin receiving holes are provided on the lower surface for joining the left and right two lower beams on the lower side (see Patent Document 1).

この壁体構築用ブロックの積上げ施工においては、下段側ブロックの第１突起部に上段側ブロックの正面壁板部の前面下部を当接させる一方、下段側ブロックの背面壁板部の後面上部に上段側ブロックの第２突起部を当接させて、下段側ブロックの上位側の左右２本の控え梁に上段側ブロックの下位側の左右２本の控え梁を載置し、下半部を下位側控え梁の各第１ピン受孔に挿入してある各連結ピンの上半部を、上位側控え梁の各第２ピン受孔に挿入する。   In the stacking construction of the wall building block, the lower part of the front wall plate of the upper block is brought into contact with the first protrusion of the lower block, while the rear wall plate of the lower block is placed on the upper rear surface of the rear wall plate. The second protrusions of the upper block are brought into contact with each other, and the left and right two lower beams of the upper block are placed on the upper and lower two upper beams of the lower block, and the lower half is The upper half part of each connecting pin inserted into each first pin receiving hole of the lower side guard beam is inserted into each second pin receiving hole of the upper side guard beam.

この壁体構築用ブロックでは、上段側ブロックの下位側の左右２本の控え梁の下面部が下段側ブロックの上位側の左右２本の控え梁の上面部に当接し、これら接合面を貫いて合計４本の連結ピンが下段側ブロックの第１ピン受孔と上段側ブロックの第２ピン受孔に挿入されるため、壁体構築用ブロックは介在する連結ピンによって積上げ施工の各ステップにおいて自立安定性を有するものである。   In this wall construction block, the lower surface portions of the two left and right stay beams on the lower side of the upper block are in contact with the upper surface portions of the left and right stay beams on the upper side of the lower block, and penetrate these joint surfaces. Since a total of four connecting pins are inserted into the first pin receiving hole of the lower block and the second pin receiving hole of the upper block, the wall building block is inserted in each step of stacking construction by the intervening connecting pins. It has self-supporting stability.

しかしながら、下段側ブロックの第１ピン孔に対する連結ピン下半部の挿入は、上段側ブロックが未だ据付位置に来ていない状態、すなわち、第１ピン受孔の位置を目視確認した状態においてなされるため、ピンの本数の多さによる煩雑さを除外すれば、作業性良く的確に行なえるのであるが、上段側ブロックの第２ピン孔に対する連結ピン上半部の挿入は、上段側ブロックが据付位置に最も接近した据付直前状態、すなわち、連結ピンの位置の目視確認が非常に困難な状態でなされるため、作業性は極めて悪く、的確な挿入作業を能率良く進めることができない。   However, the insertion of the lower half of the connecting pin with respect to the first pin hole of the lower block is performed in a state where the upper block has not yet reached the installation position, that is, in a state where the position of the first pin receiving hole is visually confirmed. Therefore, if the complexity due to the large number of pins is excluded, the work can be performed accurately and with good workability. Since the state immediately before the installation closest to the position, that is, a state in which the visual confirmation of the position of the connecting pin is very difficult, the workability is extremely poor, and an accurate insertion work cannot be efficiently performed.

確かに、壁体構築用ブロックの形状寸法が設計図面通り正確に成形されており、壁体構築用ブロックが施工図面通りに正確に据え付けられるのであれば、第２ピン受孔への連結ピン上半部の挿入は、作業性良く的確に行なえる筈なのであるが、実際の製作現場や施工現場では、製作上や施工上の誤差がかなりの頻度及び大きさで出るのが普通である。
このような実態を考慮すると、単立円形孔として形成した４個の第２ピン受孔に４本の連結ピン上半部を的確に挿入すること、すなわち、各連結ピン上半部と各第２ピン受孔が特定された一点において正しく対面配置させることは、実現はほとんど不可能である。
これは、特許出願の図面上においては実現可能なように見えても、実際上では実現不可能なことである。 Certainly, if the shape and dimensions of the wall building block are accurately formed as per the design drawing and the wall building block is installed correctly as per the construction drawing, then the top of the connecting pin to the second pin receiving hole Insertion of the half should be performed with good workability and accuracy, but in actual production sites and construction sites, errors in production and construction usually occur with a considerable frequency and size.
Considering such a situation, the upper half of the four connecting pins are accurately inserted into the four second pin receiving holes formed as the single circular holes, that is, the upper half of each connecting pin and the second half of each connecting pin. It is almost impossible to arrange the two-pin receiving holes correctly facing each other at a specified point.
This seems to be feasible on the patent application drawings, but is not feasible in practice.

また、この壁体構築用ブロックでは、正面壁板部と背面壁板の上下左右の各隅部に一体形成された上下左右４本の控え梁は、単純な角棒状に形成されたものであり、空洞部はブッロクの上下平面と左右側面に広く開放されたものであるから、胴込コンクリートの充填に当ってコンクリートの流動性が良いものであるが、その半面、ブッロクの上下平面と左右側面は角棒状の控え梁を残して広く開放されているため、ブロック全体としての構造的強度に難点があった。   Further, in this wall building block, the four upper, lower, left, and right guide beams integrally formed at the upper, lower, left, and right corners of the front wall plate and the rear wall plate are formed in a simple square bar shape. The hollow part is widely open on the upper and lower planes and left and right sides of the block, so the fluidity of the concrete is good when filling the intruded concrete. Since it is widely opened except for a square bar-shaped retaining beam, there is a difficulty in the structural strength of the entire block.

特開２００２−２５６５７６号公報JP 2002-256576 A

本発明の課題は、製作上や施工上の誤差があってもブロックの積上げ施工を作業性良く的確に行なえ、据付直後における据付位置の微調整が容易に行なえるとともに、構造的強度の高い控え梁構造を有しながら胴込コンクリートの充填作業性が良い壁体構築用ブロックを提供することである。   The problem of the present invention is that it is possible to perform the stacking construction of the blocks accurately with good workability even if there is an error in manufacturing or construction, and to easily fine-tune the installation position immediately after installation, and to keep the high structural strength. It is to provide a block for building a wall body that has a beam structure and has good workability for filling in-body concrete.

本発明の壁体構築用ブロックは、正面壁板部と背面壁板部を平行に配置し、互いに逆傾斜の二枚の斜面板部を内端側で会合させる一方、外端側で開口させた形の横倒しＶ字状断面を呈する左右一対の控え梁によって、前記正面壁板部と前記背面壁板部を一体に連結し、前記左右一対の控え梁の間に上下に連通した開放部を形成し、前記背面壁板部の上端肉厚部にピン受孔を前方に張出して形成し、前記背面壁板部の下端部に後方に向けて開口した第１の調整用切欠き溝を設け、前記正面壁板部の下端部の左右各隅部に後方に向けて開口した第２の調整用切欠き溝を設け、前記ピン受孔に下部が挿入されたガイドピンの上部を、前記背面壁板部の接合用上面の延長面より突出させたものである。   In the wall building block of the present invention, the front wall plate portion and the rear wall plate portion are arranged in parallel, and two inclined plate portions having opposite inclinations are associated with each other on the inner end side, while being opened on the outer end side. The front wall plate portion and the rear wall plate portion are integrally connected by a pair of left and right support beams having a V-shaped cross-section, and an open portion that communicates vertically between the pair of left and right support beams. Forming a pin receiving hole in the upper wall thickness portion of the back wall plate portion, and providing a first adjustment notch groove opened rearward in the lower end portion of the back wall plate portion. A second adjustment notch groove opened rearwardly at each of the left and right corners of the lower end portion of the front wall plate portion, and the upper portion of the guide pin having the lower portion inserted into the pin receiving hole, It is made to protrude from the extended surface of the upper surface for joining of a wall board part.

この壁体構築用ブロックの据付に当っては、下段側ブロックの背面壁板部の上端肉厚部のピン受孔にガイドピンの下部が挿入され、上段側ブロックの背面壁板部の前面を前記ガイドピンの上部に沿わせながら、上段側ブロックを下段側ブロックの上に降ろす。前記ガイドピンによって前後位置を規制されているため、原則として上段側ブロックは、その背面壁板部の接合用下面が下段側ブロックの背面壁板部の接合用上面に正しく対面し、また、その前面壁板部の接合用下面が下段側ブロックの前面壁板部の接合用上面に正しく対面した状態で据え付けられる。   When installing this wall building block, the lower part of the guide pin is inserted into the pin receiving hole in the upper wall portion of the rear wall plate of the lower block, and the front surface of the rear wall plate of the upper block is The upper block is lowered onto the lower block while being along the upper portion of the guide pin. Since the front and rear positions are regulated by the guide pins, as a general rule, the lower block of the upper wall side of the upper block correctly faces the upper surface of the lower wall block and the upper surface of the lower wall block. The front wall plate portion is installed in a state where the lower surface for bonding of the front wall plate portion correctly faces the upper surface for bonding of the front wall plate portion of the lower block.

このように本発明においては、下段ブロック側のガイドピンは背面壁板部の接合用上面に立設されたものではなくて、背面壁板部の前方に張出した上端肉厚部に配置されたものであり、また、ガイドピンの上部は上段側ブロックの背面壁板部の接合用下面の孔部などに差し込まれるものではなくて、上段側ブロックの背面壁板部の前面がそれに沿って降ろされて来るものであるから、下段側ブロックに対する上段側ブロックの据付は、ガイドピンの位置を目視確認しながら作業性良く的確に行なえる。水平積みにおいてブロックの転倒がガイドピンによって制止されて自立安定するため、施工時の安全性に優れている。   Thus, in the present invention, the guide pin on the lower block side is not erected on the upper surface for joining of the back wall plate part, but is disposed on the upper end thick part projecting forward of the back wall plate part. In addition, the upper part of the guide pin is not inserted into the hole on the lower surface for joining of the rear wall plate part of the upper block, and the front surface of the rear wall plate part of the upper block is lowered along with it. Therefore, the installation of the upper block with respect to the lower block can be accurately performed with good workability while visually confirming the position of the guide pin. In the horizontal stacking, the fall of the block is restrained by the guide pin and becomes independent and stable, so it is excellent in safety during construction.

壁体構築用ブロックの製作上または施工上の誤差によって、据え付けた上段側ブロックの水平位置と高さに多少の狂いがあっても、背面壁板部の下端部の第１の調整用切欠き溝と前面壁板部の下端隅部の第２の調整用切欠に溝に調整作業用工具を差し入れて、上段側ブロックの水平位置および高さ位置を的確に微調整することができるため、ブロックの据付け作業が容易となり、施工性が大幅に向上する。   The first adjustment notch at the lower end of the back wall plate even if the horizontal position and height of the installed upper block are slightly out of alignment due to errors in the construction or construction of the wall building block Since the adjustment work tool can be inserted into the groove in the groove and the second adjustment notch at the lower end corner of the front wall plate, the horizontal position and height position of the upper block can be finely adjusted accurately. The installation work becomes easier and the workability is greatly improved.

上段側ブロックが正しい位置に据え付けられた後、正面壁板部と背面壁板部間の空洞部に胴込コンクリートが充填されるのであるが、胴込コンクリートは、左右の控え梁の外側空間と、左右の控え梁間の内側空間に円滑に流動し、各控え梁を密実に包摂した状態で固化することによって、一体化の高いブロック積み壁体が構築される。
左右に配置された控え梁は、互いに逆傾斜の二枚の斜面板部を内端側で会合させる一方、外端側で開口させた形の横倒しＶ字状断面を呈するものであるから、胴込コンクリート充填時の流動性を害することなく、ブロック全体の構造的強度を高めることができる。 After the upper block is installed at the correct position, the hollow concrete between the front wall plate and the rear wall plate is filled with the trunk concrete. By smoothly flowing into the inner space between the left and right girder beams and solidifying each of the girder beams densely, a highly integrated block stacking wall is constructed.
Since the stay beams arranged on the left and right sides have two inclined sloped plate portions that are oppositely inclined to each other on the inner end side and exhibit an overturned V-shaped cross section that is open on the outer end side, The structural strength of the entire block can be increased without harming the fluidity when filling concrete.
