。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a construction method for forming the surface of a concrete structure into a rough surface, and a formwork used in the construction method.
従来の技術
従来、コンクリート擁壁、コンクリート建造物、境界壁
等を現場打ちする場合は、内面を滑面となした型枠を用
いてコンクリートを打設しているもので、表面を平面的
なフラットに成型しているものである。Conventional technology Traditionally, when concrete retaining walls, concrete buildings, boundary walls, etc. were poured on-site, concrete was poured using formwork with a smooth inner surface. It is molded flat.
発明が解決しようとする問題点
しかしながら、建造物の外壁や内壁、また花壇等におい

を要する欠点があった。Problems to be Solved by the Invention However, flat concrete surfaces are monotonous and lack aesthetic appeal on the outer and inner walls of buildings, flower beds, etc., and are susceptible to light reflection, especially on road retaining walls. In some cases, it leads to the destruction of the natural environment. Therefore,
In recent years, the surface of concrete buildings has been roughened using an electric vibrator after forming, but this method has the drawback of requiring time and effort.
問題点を解決するための手段
この様な問題点を解消する目的において、本発明は型枠

等を特徴とするものである。Means for Solving the Problems In order to solve the above problems, the present invention adheres and solidifies foamed urethane to the inner surface of a formwork, and uses the formwork to form a concrete structure. The surface can be roughened at low cost, and is characterized by diffused reflection of light, improved aesthetics, improved acoustic effects, and the ability to protect the natural environment.
以下、実施用例図により本発明の詳細な説明する。Hereinafter, the present invention will be explained in detail with reference to practical example figures.

構造物４の外面に凹凸粗面５を形成すべくなして成るも
のである。A formwork 2 for forming a rough surface is formed with a foam 1 such as urethane foam adhered and solidified on the inner surface, and the formwork 2 for forming a rough surface is assembled and concrete 3 is cast inside. After curing, the rough surface molding frame 2 is removed from the mold to form an uneven rough surface 5 on the outer surface of the concrete structure 4.
作用、効果
つぎに、実施用例図により本発明の作用効果を説明する
。Functions and Effects Next, the functions and effects of the present invention will be explained with reference to practical example diagrams.
粗面成型用型枠２は、内面に発泡ウレタンのニジストマ

粗面５に成型されるものである。粗面成型用型枠２は反
復使用するものであるが、使用中に発泡体１が剥離した
ら再びニジストマーを吹付けて修理し得るものである。The mold 2 for forming a rough surface can be easily solidified by spraying foamed urethane nidistomer onto the inner surface, and the surface is solidified into an uneven surface. Foam 1 like the urethane foam
When the formwork 2 for forming a rough surface is assembled appropriately according to the type of structure, the inside is filled with concrete 3, and the mold is removed after curing, the outer surface of the concrete structure 4 is formed into an uneven and rough surface 5. It is something that will be done. The mold 2 for forming a rough surface is used repeatedly, but if the foam 1 peels off during use, it can be repaired by spraying the nidistomer again.
なお、発泡体１は、通常の型枠を組立した後に内面にエ
ラストマーを吹付けて発泡固化させてもよいものである
。なお発泡体１の保温効果によりコンクリートのサイド
養生性も向上するものである。Note that the foam 1 may be formed by assembling a normal mold and then spraying an elastomer onto the inner surface to foam and solidify the foam. Note that the heat retaining effect of the foam 1 also improves the side curing properties of concrete.
前記した様に、本発明になる施工法によりコンクリート

、前記した様な顕著な諸効果を奏するものである。As described above, by the construction method of the present invention, the uneven surface 5 is formed on the outer surface of the concrete structure 4 at the same time as the formwork is removed, which saves time and effort compared to the conventional case of using an electric pick. It brings about the remarkable effects mentioned above, such as being able to save money and reduce construction costs.
