本考案は、盛り土や切土などの土を支える擁壁
を構築するためのアンカー付コンクリートブロツ
クに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a concrete block with an anchor for constructing a retaining wall that supports soil such as embankment or cutting.
擁壁の種類には、コンクリートの重力式、鉄筋
コンクリートの片持ち梁式、控え壁や支え壁など
の扶壁式のほか、石積みやコンクリートブロツク
積みによるものがある。
Types of retaining walls include concrete gravity type, reinforced concrete cantilever type, retaining walls such as buttresses and supporting walls, as well as those made of masonry or concrete blocks.
このような擁壁は、一般的には土圧およびその
土の上に載る荷重、地震力、地盤の支持力および
擁壁の自重などを条件として、部材および擁壁全
体の転倒やすべり出しに対する安全性を勘案して
設計する。 In general, retaining walls of this type are designed to ensure safety against overturning or sliding of the members and the retaining wall as a whole, based on conditions such as earth pressure, the load placed on the soil, seismic force, the bearing capacity of the ground, and the retaining wall's own weight. Design with gender in mind.
従つて、コンクリートブロツクによる擁壁も、
従来はブロツクの自重を大きくして、ブロツク相
互間の結着力を補つていた。 Therefore, retaining walls made of concrete blocks also
Conventionally, the weight of the blocks was increased to compensate for the binding force between the blocks.
〔考案が解決しようとする問題点〕
コンクリートブロツクの自重が大きいと、その
搬送や設置の際のハンドリングのために１個当た
りのブロツクの大きさが制限され、大きなブロツ
クを製作することができない。[Problems to be solved by the invention] When the weight of concrete blocks is large, the size of each block is limited due to handling during transportation and installation, making it impossible to manufacture large blocks.
本考案者は、先に、擁壁用ブロツクを本体とア
ンカーに分割し、使用に際して両者を一体にして
擁壁を構築するコンクリートブロツクを提案し
た。そのブロツクによれば、地盤との結着力はア
ンカーによつて得られるため、自重は余り要しな
いということを知見した。 The present inventor previously proposed a concrete block in which a retaining wall block is divided into a main body and an anchor, and when used, the two are integrated to construct a retaining wall. According to the block, it was discovered that because the binding force with the ground was obtained by the anchor, it did not require much of its own weight.
本考案は、このような知見に基づくものであ
り、コンクリートブロツクの軽量化による施工の
容易化、安全化を図ることを目的とするものであ
る。 The present invention is based on such knowledge and aims to make construction easier and safer by reducing the weight of concrete blocks.
本考案は、背部に係合部を有するブロツク本体

The present invention provides a concrete block with an anchor for a retaining wall, which has a block main body having an engaging part on the back, and an anchor having a locking part at its tip that engages with the engaging part on the back of the block main body. This is an ultra-lightweight concrete block with an anchor, whose main body is made of foamed resin for the inside, concrete for the outer layer, and galvanized iron plate for the surface.
以下、本考案を図面に示す実施例に基づいて具
体的に説明する。
Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings.
第１図は本考案に係るアンカー付コンクリート

である。図中１はブロツク本体、２はアンカーで
ある。ブロツク本体１は背部にヘアピンの頭状の
係合部１ａが形成され、アンカー２には、この係
合部１ａに嵌まり込む係止部２ａを先端に有する
アーム部２ｂが一体に形成されている。 FIG. 1 is a sectional view showing an embodiment of a concrete block with an anchor according to the present invention, and FIG. 2 is a perspective view. In the figure, 1 is the block body and 2 is the anchor. The block body 1 has a hairpin head-shaped engagement part 1a formed on its back, and the anchor 2 is integrally formed with an arm part 2b having a locking part 2a at its tip that fits into this engagement part 1a. There is.
ブロツク本体１の構造は、内部は発泡スチロー
ル等の発泡樹脂を芯材１０として構成され、その
表面に金網ラス１１を被覆し、これにモルタルを
付着させ、コンクリートあるいはプラスターの表
皮層１２を形成し、表面層１３を亜鉛鉄板で鋳込
み成型により形成している。図中１４は番線等で
形成した補強筋である。 The structure of the block body 1 consists of a core material 10 made of foamed resin such as styrofoam, the surface of which is covered with wire mesh lath 11, mortar is attached to this, and a skin layer 12 of concrete or plaster is formed. The surface layer 13 is formed of a galvanized iron plate by casting. In the figure, reference numeral 14 indicates reinforcing bars formed of wires or the like.
アンカー２の方も、同様に発泡樹脂の芯材２
０、金網ラス２１、表皮層２２、表面層２３を形
成する。 Anchor 2 is also made of foamed resin core material 2.
0, a wire mesh lath 21, a skin layer 22, and a surface layer 23 are formed.
第３図は、アンカー２の他の例を示すものであ
