Description

ガレージに打設する鉄筋コンクリートの目地に植栽するための目地保持用スペーサに関する。   The present invention relates to a joint retaining spacer for planting in a joint of reinforced concrete to be placed in a garage.

従来工法として図1及び図1におけるX矢視図（図2）に示すように、2枚の幕板Aを並列し、その対面間に目地1を形成するための間隔を保持する間柱2を挟入し、幕板Aが動かないように、双方の外側面に添わせて数本の鉄筋3を立設して固定すると共に、幕板Aの端部上面を直角に切り欠いて段部A1を形成し、幕板Aと直交する方向に２枚の幕板Bを並列し、その幕板B間の対面間に目地1を形成するため、幕板Bの下端部を下方へ突設して断面L字形の突部B1を形成し、突部B1と段部A1を凹凸嵌合し、幕板Aと幕板Bの交差部をビス4で連結し、幕板Aと幕板Bに囲まれる複数の各区画に砕石と鉄筋を配設し、コンクリートを各区画に打設してガレージのコンクリート敷設面を形成し、目地1に植栽している。   As shown in the X arrow view (Fig. 2) in Fig. 1 and Fig. 1 as a conventional construction method, two curtain plates A are arranged side by side, and a stud 2 is used to maintain a space for forming a joint 1 between the facing surfaces. In order to prevent the curtain plate A from moving, several rebars 3 are erected and fixed along the outer sides of both sides, and the upper surface of the edge of the curtain plate A is cut at a right angle to form a stepped portion. A1 is formed, and two curtain plates B are juxtaposed in a direction perpendicular to the curtain plate A, and the lower end of the curtain plate B projects downward to form a joint 1 between the facing surfaces of the curtain plates B. To form a projection B1 having an L-shaped cross section, the projection B1 and the stepped portion A1 are concavo-convexly fitted, and the intersection of the curtain plate A and the curtain plate B is connected with a screw 4, and the curtain plate A and the curtain plate B Crushed stones and reinforcing bars are placed in each of the plurality of sections surrounded by the concrete, and concrete is laid on each section to form a concrete laying surface of the garage, which is planted on the joint 1.

敷地内の空地に敷設される舗装材によって形成される目地に納められて設置される補助舗装材であって、目地の幅を備えた水平部と、水平部における長さ方向に亘る両縁部からそれぞれ下方に突き出して補助舗装材を下側開口のチャンネル状とする脚部とを有し、前記水平部が舗装材の上面以下に位置されるよう脚部を目地の地盤に埋め込んで設置すると共に水平部に複数の貫通孔を形成し、目地に植えた植物の成長を妨げないようにしている。   Auxiliary pavement material that is installed in a joint formed by a pavement material laid in an open space in the site, and has a horizontal part with a joint width and both edges in the length direction of the horizontal part Each leg projecting downward from the base, and the auxiliary pavement is formed into a channel shape with a lower opening, and the leg is embedded in the joint ground so that the horizontal part is located below the upper surface of the pavement. At the same time, a plurality of through holes are formed in the horizontal portion so that the growth of the plant planted on the joint is not hindered.

しかしながら該発明には本考案のように、幕板を縦横に交差させ各区画を形成するための目地保持用スペーサの記載はない。   However, the invention does not include a joint holding spacer for crossing the curtain plate vertically and horizontally to form each section as in the present invention.

特開2013−64295号公報 本考案に係る目地保持用スペーサS1とS2の実施状態を示す平面図3において、目地保持用スペーサS1は、2枚の幕板C、Cの間隔を保持して並列し、対面間に目地1を設けて植物5を植え込み、他の2枚の幕板D、Dを間隔を保持して並列し、対面間に目地1を設けて植物5を植え込み、幕板C、Cを幕板D、Dと直交させて複数の区画6を形成し、各区画6に砕石7を敷き詰めると共に鉄筋8を配筋し、モルタルを打設して鉄筋コンクリート製の区画6を有する複数のガレージ敷設面9の連接箇所に形成される目地1にそれぞれ植物5を植裁するものであり、幕板C、Cを直線状に繋ぐ場合には平面視において方形の目地保持用スペーサS1を用い、幕板C、Cと幕板D、DをT字形に繋ぐ場合には平面視においてT字形の目地保持用スペーサS2を用いるものである。JP, 2013-64295, A In plan view 3 showing the state of implementation of joint holding spacers S1 and S2 according to the present invention, joint holding spacer S1 is arranged in parallel while maintaining the distance between two curtain plates C, C. Then, planting the plant 5 with the joint 1 between the faces, and placing the other two curtains D, D side by side with a gap, planting the plant 5 with the joint 1 between the faces, and the curtain C , C is perpendicular to the curtain plates D, D to form a plurality of sections 6, each section 6 is laid with crushed stone 7 and reinforcing bars 8 are arranged, and mortar is placed to form a plurality of sections 6 made of reinforced concrete. Plant 5 is planted on the joint 1 formed at the joint location of the garage laying surface 9 of the garage, and when the curtain plates C and C are connected in a straight line, a square joint holding spacer S1 is used in plan view. When the curtain plates C, C and the curtain plates D, D are connected in a T shape, a T-shaped joint holding spacer S2 is used in a plan view.

特開2013−64295号公報に係る発明は、敷地内の空地に敷設される舗装材によって形成される目地に納められて設置される補助舗装材であり、チャンネル状部材の開口を下向きに目地のある地盤に、その水平面を舗装材の上面より低く位置するように配置し、水平面上に植栽するのであるが、植物を目地のある地盤に直接植え込むものではなく生育が遅れ或いは枯死する欠点がある。   The invention according to Japanese Patent Laid-Open No. 2013-64295 is an auxiliary pavement material that is placed and installed in a joint formed by a pavement material laid in an open space in a site, and the opening of the channel-shaped member faces downward. It is placed on a certain ground so that its horizontal plane is lower than the upper surface of the pavement and planted on the horizontal plane, but it does not directly plant the plant on the ground with joints, but there is a disadvantage that growth is delayed or withered is there.
