〔産業上の利用分野〕
この発明は主として現場打ちで、表面に凹凸模様のある
コンクリートを打設する方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] This invention relates primarily to a method for pouring concrete with an uneven pattern on its surface, mainly by casting on site.
従来、現場打設で表面に凹凸のあるコンクリートを形成
するには、シリコーン樹脂や発泡スチロール樹脂を凹凸
成形した表面板をコンパネやメタルフオームなどの型枠
の内面に貼り付けて、にコンクリートを打設してきた。Conventionally, in order to form concrete with an uneven surface by pouring it on-site, a surface plate made of silicone resin or expanded polystyrene resin was attached to the inner surface of a formwork such as a control panel or metal form, and then concrete was poured. I've done it.
これらの内貼り材料は通気性・透水性がないため、コン
クリートの打設時に凸部内の空気が抜けず、シャープな
模様が出せない、又、スランプの大きいコンクリートを
打つと、水が抜けずコンクリート強度が低下するなどの
問題点があった。These inner lining materials do not have air permeability or water permeability, so when concrete is poured, air cannot escape from the convex parts, making it impossible to create sharp patterns.Also, if concrete with a large slump is poured, water will not escape and the concrete will not be able to escape. There were problems such as a decrease in strength.
この問題を解決するため、この発明では凹凸加工され、
少なくとも凸部に小孔を設けた薄板を表面板として型枠
の内面に取付ける。In order to solve this problem, in this invention, uneven processing is applied,
A thin plate with small holes in at least the convex portion is attached to the inner surface of the formwork as a surface plate.
このように構成すると、凹凸内の空気とコンクリートの
余剰水は小孔から押し出され、シャープな凹凸を持ち、
強度のあるコンクリートが打設できる。With this configuration, the air in the unevenness and excess water in the concrete are pushed out through the small holes, creating sharp unevenness.
Strong concrete can be cast.
以下、本発明の実施例を図面に基づき詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail based on the drawings.
第１図に示すように、厚さ０．１〜１．０ｍｍ厚の薄鋼
板１の全面に直径０．１〜１．０ｍ諺程度の小孔２と深
さ１０ ｍｍ前後の凹凸模様３を付設し表面板Ａとする
。表面板の形成方法は、例えば、第２図に示すように、
多数の針４を植えた針ロール５１とゴムロール５２の間
を通して全面に小孔２を設け、続いて二本の彫刻ロール
５３の間を通して凹凸模様３を形成する。As shown in Fig. 1, a small hole 2 with a diameter of about 0.1 to 1.0 mm and an uneven pattern 3 of about 10 mm in depth are formed on the entire surface of a thin steel plate 1 with a thickness of 0.1 to 1.0 mm. A surface plate A is attached. The method for forming the surface plate is, for example, as shown in FIG.
Small holes 2 are provided on the entire surface by passing between a needle roll 51 in which a large number of needles 4 are planted and a rubber roll 52, and then an uneven pattern 3 is formed by passing between two engraving rolls 53.
このような表面板Ａを、第３図に示すように、水の通り
道７となる。Such a surface plate A becomes a passage 7 for water, as shown in FIG.
このように合成された型枠を通常の合板パネルと同様に
現場で組み立て、表面板を内側にしてコンクリート８を
打設す。The formwork thus synthesized is assembled on site in the same manner as a normal plywood panel, and concrete 8 is poured with the surface plate facing inside.
凸部内の空気は小孔を通じて押し出されるのでコンクリ
ートの廻りがよく、気泡が出来ず、シャープな凹凸模様
が形成できる。又、スランプの大きいコンクリートを打
った場合、余剰水が小孔から）８み出されるのでコンク
リートの強度低下が抑えられる。The air inside the convex portion is forced out through the small holes, allowing the concrete to move around easily, preventing the formation of air bubbles and creating a sharp uneven pattern. Furthermore, when concrete with a large slump is cast, surplus water is expelled from the small holes, which prevents the strength of the concrete from decreasing.
表面板に薄板を用いても、全体の側圧は合板パネルが支
持するし、部分的な力は凹凸がアーチ構造となっている
ので、容易に押し潰されない。Even if a thin plate is used for the surface plate, the entire lateral pressure is supported by the plywood panel, and the unevenness has an arched structure to absorb partial force, so it is not easily crushed.
尚、本発明において、薄板は通常、鋼単板を用いるが、
簡単に凹凸が押し潰されない程度の剛性があれば、合成
樹脂の薄板などを用いることも可能である。例えば、多
数の小孔を付設した０、３〜０．７ ｔｍ厚のポリスチ
レンシートを熱圧成形で凹凸を設けた表面板は、熱圧成
形の型があれば大量生産で安価に入手でき好都合である
。In addition, in the present invention, a steel veneer is usually used as the thin plate, but
It is also possible to use a thin plate of synthetic resin, etc., as long as it has enough rigidity to prevent the unevenness from being easily crushed. For example, a surface plate made by heat-pressing a 0.3 to 0.7 tm-thick polystyrene sheet with many small holes and creating irregularities can be mass-produced at low cost if a hot-pressing mold is available. It is.
又、薄板は単板でなく、第４図に示すように、薄鋼板１
の裏面に不織布９などの通気性・透水性があり、多少の
伸長性のあるシート状物を貼り合わせたり、二枚の薄鋼
板の間に同様シート状物を挟み込んだものなどを用いて
もよい。凹凸加工時に伸長するし、通気性・透水性があ
る上、比較的大きな孔を開けても不織布によりセメント
ミルクの流出がなく好都合である。In addition, the thin plate is not a single plate, but a thin steel plate 1 as shown in Figure 4.
You can also use a sheet-like material with air permeability, water permeability, and some stretch, such as non-woven fabric 9, attached to the back side of the material, or a similar sheet-like material sandwiched between two thin steel plates. good. It expands when textured, has air permeability and water permeability, and is advantageous because the nonwoven fabric prevents cement milk from flowing out even when relatively large holes are made.
又、小孔の形成は針ロール５１によらず、彫刻ロールに
尖端を付設し、°彫刻ロール間を通す工程で凸部の先に
小孔をあけてもよい。残気・税水の目的からは凸部の先
端に孔があれば充分であるからである。又、小孔・凹凸
模様の形成はロールによらずプレス加工など（亀の成形
方法によってもよい。Further, the small holes may be formed without using the needle roll 51, by attaching a pointed end to the engraving roll and making the small hole at the tip of the convex part in the step of passing between the engraving rolls. This is because it is sufficient to have a hole at the tip of the convex portion for the purpose of removing residual air and water. Moreover, the formation of small holes and uneven patterns may be performed by pressing or other methods (tortoise molding method may also be used) instead of using rolls.
模様パターンとしては石模様・石積み模様・レンガ積み
模様・幾何模様など特に限定するものではない。The pattern is not particularly limited, such as a stone pattern, a masonry pattern, a brickwork pattern, or a geometric pattern.
又、表面板と複合する型枠は合板パネルに限らず、メタ
ルフォム・網体などコンクリートの側圧に耐えるもので
あればよい。Further, the formwork to be combined with the surface board is not limited to plywood panels, and may be made of metal foam, netting, etc. as long as it can withstand the lateral pressure of concrete.
な金型を大量に用意するのは初期投資が大きいし、多ｆ
ｔ類の模様入り金型を保有するのは投下資本がが少なく
、多様な需要に応することが可能となる。Preparing a large number of molds requires a large initial investment and requires a lot of investment.
Owning T-class patterned molds requires little investment capital and allows us to meet a variety of demands.
この発明はこのように構成されているので、次のような
特長を有する。Since the present invention is configured as described above, it has the following features.
■ 表面板は薄板に小孔と凹凸模様を施すだけでよいの
で安価で、大量に供給できる。■ The surface plate is inexpensive and can be supplied in large quantities because it is only necessary to make small holes and an uneven pattern on a thin plate.
■ 小孔から空気・余剰水が押し出されるので、シャー
プで強度の大きい凹凸コンクリートが打設できる。■ Since air and excess water are forced out of the small holes, sharp and strong uneven concrete can be cast.
