Abstract
Description
本発明は、タイル等の目地を模した目地状模様を有したプレキャストパネル等のセメント組成体、その製造方法、及びその表面仕上げ方法に関する。 The present invention relates to a cement composition such as a precast panel having a joint pattern imitating joints such as tiles, a manufacturing method thereof, and a surface finishing method thereof.
従来、建物の外壁材等には、プレキャストコンクリート（ＰＣａ）板や押出成形セメント板などのプレキャストパネルが使用されている。そして、その意匠性を高めたパネルとして、上記のプレキャストパネルにモルタルや接着剤等でタイルや石、レンガ等（以下、「タイル」と総称する）を張り付けてなるパネルも使用されている。
但し、後者のパネルのタイルは、経年劣化などにより剥離・剥落の危険がある。そのため、この問題を回避すべく、最近では、予めプレキャストパネルの表面に格子状の溝部を設け、その溝部を目地部に見立てて着色してタイルに似せて仕上げることが行われている。すなわち、プレキャストパネルの表面における溝部を目地相当部分とし、溝部以外の部分をタイル相当部分として、互いに色違いで塗装することにより、タイルを模擬している。
Conventionally, a precast panel such as a precast concrete (PCa) plate or an extrusion-molded cement plate is used for a building outer wall material or the like. In addition, as a panel with improved design properties, a panel in which tiles, stones, bricks, etc. (hereinafter collectively referred to as “tiles”) are attached to the above-mentioned precast panels with mortar, adhesive, or the like is also used.
However, the tiles of the latter panel have a risk of peeling or peeling off due to deterioration over time. Therefore, in order to avoid this problem, recently, a grid-like groove portion is provided in advance on the surface of the precast panel, and the groove portion is colored like a joint portion and finished to resemble a tile. That is, the tiles are simulated by painting the groove portions on the surface of the precast panel as joints and painting the portions other than the grooves as tile equivalents with different colors.
しかしながら、これらタイル相当部分及び目地相当部分のどちらも塗装仕上げだと、質感に乏しく本物のタイルのようには見えない。 However, if both the tile-corresponding portion and the joint-corresponding portion are painted, the texture is poor and it does not look like a real tile.
本発明は、上記のような従来の問題に鑑みなされたものであって、タイル張りの質感を醸し出す目地状模様を有したセメント組成体、その製造方法、及びその表面仕上げ方法を提供することを目的とする。 The present invention has been made in view of the above-described conventional problems, and provides a cement composition having a joint-like pattern that produces a tiled texture, a manufacturing method thereof, and a surface finishing method thereof.

＝＝＝第１実施形態＝＝＝
図１Ａは、第１実施形態に係る目地状模様を有したプレキャストパネル１の平面図である。また、図１Ｂは、図１Ａ中のＢ−Ｂ矢視図である。
プレキャストパネル１はコンクリート製の板状部材を本体１ｓ（セメント組成体に相当）とする。そして、この本体１ｓの略平坦な表面１ａには、所定範囲に亘ってタイルの目地部を模した溝部３，３…が形成されている。図示例では、上記所定範囲は表面１ａの全面であり、つまり目地状模様が表面１ａの全面に亘って形成されている。但し、上記所定範囲は全面でなくても良く、表面１ａの一部でも良い。以下では、溝部３のことを目地相当部分３とも言い、表面１ａにおける溝部３，３…以外の残部（島状に残った部分）のことを、タイル相当部分５，５…とも言う。
=== First Embodiment ===
FIG. 1A is a plan view of a precast panel 1 having a joint pattern according to the first embodiment. Moreover, FIG. 1B is a BB arrow line view in FIG. 1A.
The precast panel 1 has a concrete plate-like member as a main body 1s (corresponding to a cement composition). Then, on the substantially flat surface 1a of the main body 1s, groove portions 3, 3... Simulating tile joints are formed over a predetermined range. In the illustrated example, the predetermined range is the entire surface 1a, that is, a joint pattern is formed over the entire surface 1a. However, the predetermined range may not be the entire surface, and may be a part of the surface 1a. Below, the groove part 3 is also referred to as a joint equivalent part 3, and the remaining part (the part remaining in an island shape) other than the groove parts 3, 3... On the surface 1 a is also referred to as a tile equivalent part 5, 5.
タイル相当部分５は、塗装されている。つまり塗料７によって着色されている。塗料７の種類は、模擬しようとするタイルの種類に応じて選択される。例えば、石板状タイルを模す場合には、石粉を混ぜた塗料７が使用され、レンガタイルを模す場合には、レンガ色の塗料７が使用され、金属タイルを模す場合には、金属色の塗料７が用いられる。 The tile equivalent part 5 is painted. That is, it is colored by the paint 7. The type of paint 7 is selected according to the type of tile to be simulated. For example, when imitating a stone tile, paint 7 mixed with stone powder is used, when imitating a brick tile, brick-colored paint 7 is used, and when imitating a metal tile, metal Color paint 7 is used.
この塗装は、タイル相当部分５のみに施しても良いし、タイル相当部分５に加えて、タイル相当部分５以外の部分たる溝部３に施しても良い。前者のようにタイル相当部分５にのみ塗装する場合には、溝部３を不図示のマスキングテープ等により覆ってマスキングしつつ塗料７を塗れば良い。そして、これによれば、溝部３には塗料７が付着しないので、塗装後に溝部３に充填すべき目地材９の溝部３への接着性を高めることができる。 This coating may be applied only to the tile-corresponding portion 5, or may be applied to the groove portion 3 other than the tile-corresponding portion 5 in addition to the tile-corresponding portion 5. When painting only on the tile-corresponding portion 5 as in the former case, the coating 7 may be applied while masking the groove portion 3 by covering it with a masking tape (not shown). And according to this, since the coating material 7 does not adhere to the groove part 3, the adhesiveness to the groove part 3 of the joint material 9 which should be filled into the groove part 3 after coating can be improved.
一方、溝部３たる目地相当部分３には、塗料ではない謂わば本物の目地材９が充填されている。すなわち、この目地材９としては、通常のタイル張りの際に使用されるものと同種の充填材が使用される。例えば、セメントやモルタル、樹脂モルタル等のセメントを主材とする充填材が使用される。そして、これにより、この目地相当部分３には、本物の目地材９が充填されているので、プレキャストパネル１は、本物のタイル張りと同様の質感を醸し出す。 On the other hand, the joint-corresponding portion 3 that is the groove portion 3 is filled with a so-called real joint material 9 that is not a paint. That is, as the joint material 9, the same kind of filler as that used in normal tiling is used. For example, a filler mainly composed of cement such as cement, mortar, or resin mortar is used. Thus, since the joint-corresponding portion 3 is filled with the real joint material 9, the precast panel 1 brings on the same texture as that of the real tile.
ここで、望ましくは、図１Ｂ中の一部拡大図に示すように、溝部３の縁部３ｅ（つまり、タイル相当部分５と溝部３との境界部分３ｅ）が、目地材９で覆われていないようにすると良い。そうすれば、目地材９が、タイル相当部分５と面一にはならずに、同タイル相当部分５よりもへこむようになり、これにより、目地材９を充填後の溝部３にも適度な陰影が付与されて、より一層タイル張りの質感を醸し出すようになる。 Here, preferably, as shown in a partially enlarged view in FIG. 1B, the edge 3 e of the groove 3 (that is, the boundary portion 3 e between the tile equivalent portion 5 and the groove 3) is covered with the joint material 9. It is better not to. By doing so, the joint material 9 does not become flush with the tile equivalent part 5 but becomes dented more than the tile equivalent part 5, and accordingly, the joint part 9 is also suitable for the groove part 3 after filling. Shading is added to create a more tiled texture.
また、望ましくは、同拡大図に示すように、溝部３の縁部３ｅは角張っていると良い。そしてこのようになっていれば、上述と同様に陰影を高めることができる。 Desirably, the edge 3e of the groove 3 is angular as shown in the enlarged view. And if it becomes like this, a shadow can be heightened similarly to the above-mentioned.
図２Ａ乃至図３Ｅは、このプレキャストパネル１の製造方法の説明図であり、何れの図も縦断面視で示している。
先ず、図２Ａのように、成形すべきプレキャストパネル１の外形形状に対応させて型枠２１を組む。図示例では、型枠２１は、底板２１ａと、底板２１ａの四辺にそれぞれ対応して配された四つの側板２１ｂ，２１ｂ…と、を有している。また、プレキャストパネル１の表面１ａを形成すべき底板２１ａには、形成すべき溝部３，３…に対応する各位置に、予め目地棒２３，２３…が平面視で格子状に配置されている。
2A to 3E are explanatory views of the method for manufacturing the precast panel 1, and each figure is shown in a longitudinal sectional view.
First, as shown in FIG. 2A, the mold 21 is assembled in accordance with the outer shape of the precast panel 1 to be molded. In the illustrated example, the mold 21 has a bottom plate 21a and four side plates 21b, 21b,... Arranged corresponding to the four sides of the bottom plate 21a. Further, joint rods 23, 23... Are arranged in a lattice shape in plan view at positions corresponding to the grooves 3, 3... On the bottom plate 21a on which the surface 1a of the precast panel 1 is to be formed. .
そうしたら、図２Ｂ及び図２Ｃのように型枠２１内にコンクリート１Ｃを打設し、打設したコンクリート１Ｃの硬化後に型枠２１を脱型し、これにより、図２Ｄのようにプレキャストパネル１の本体１ｓが成形される。なお、この脱型時には、底板２１ａの目地棒２３もプレキャストパネル１の本体１ｓから取り外され（図２Ｄ）、これにより、同本体１ｓの表面１ａには格子状に溝部３，３…が形成される（以上、成形工程に相当）。 Then, concrete 1C is placed in the mold 21 as shown in FIGS. 2B and 2C, and after the cast concrete 1C is hardened, the mold 21 is demolded. Thus, as shown in FIG. 2D, the precast panel 1 is cast. The main body 1s is molded. During the demolding, the joint rod 23 of the bottom plate 21a is also removed from the main body 1s of the precast panel 1 (FIG. 2D), thereby forming grooves 3, 3,... On the surface 1a of the main body 1s. (Corresponding to the molding process).
なお、この例では溝部３，３…の形成に目地棒２３，２３…を用いたが、用いなくても良い。すなわち、型枠２１の底板２１ａに目地棒２３，２３…を配置しないまま同型枠２１内にコンクリート１Ｃを打設することにより、表面１ａに凹部のない略平坦面のプレキャストパネル１の本体１ｓを成形し、この後で、目地切りカッター等で同本体１ｓの表面１ａを削って溝部３，３…を形成しても良い。 In this example, the joint rods 23, 23,... Are used for forming the grooves 3, 3,. That is, by placing concrete 1C in the mold 21 without placing the joint rods 23, 23... On the bottom plate 21a of the mold 21, the main body 1s of the precast panel 1 having a substantially flat surface without a recess on the surface 1a. After this, the surface 1a of the main body 1s may be shaved with a joint cutting cutter or the like to form the grooves 3, 3,.
次に、図３Ｂ及び図３Ｃに示すように、溝部３，３…が形成された表面１ａを、模擬すべきタイル色の塗料で塗装する（塗装工程に相当）。塗装方法はスプレー３１等で塗料７を吹き付けても良いが、刷毛塗りでも良い。また、この塗装の際に、各溝部３，３…をマスキングしても良いし、しなくても良い。そして、溝部３をマスキングしない場合には、マスキング作業を省略できて作業手間の削減を図れる。なお、ここで、後者の場合、つまり、溝部３のマスキングをしない場合には、望ましくは、表面１ａにおけるタイル相当部分５と目地相当部分３との境界部分たる前記縁部３ｅ及びその近傍部分に塗りこぼしが出ないように、例えば、タイル相当部分５だけでなく、目地相当部分３たる溝部３にも塗装すると良い。 Next, as shown in FIGS. 3B and 3C, the surface 1a on which the groove portions 3, 3,... Are formed is painted with a tile color paint to be simulated (corresponding to a painting process). The paint 7 may be sprayed with the spray 31 or the like, but may be brushed. Further, at the time of this coating, the grooves 3, 3... May or may not be masked. And when not masking the groove part 3, a masking operation | work can be abbreviate | omitted and reduction of an operation | work effort can be aimed at. Here, in the latter case, that is, when the groove portion 3 is not masked, it is desirable that the edge portion 3e as a boundary portion between the tile equivalent portion 5 and the joint equivalent portion 3 on the surface 1a and the vicinity thereof. For example, it is preferable to paint not only the tile equivalent part 5 but also the groove part 3 which is the joint equivalent part 3 so as not to spill the paint.
そうしたら、図３Ｄ及び図３Ｅに示すように各溝部３，３…に対して、それぞれ目地材９，９…を塗料７の上から充填する（充填工程に相当）。充填には鏝３３を用いると良く、そうすれば、溝部３からタイル相当部分５へと若干はみ出させながら目地材９を充填するので、溝部３内に密実に充填可能となる。また、鏝３３によれば、溝部３からはみ出してタイル相当部分５に付着した目地材９も、掻き落としにより容易に除去可能である。なお、タイル相当部分５に付着残存した目地材９は、最終的には、ウエス等の適宜な拭き取り部材によって拭き取られる。これにより、タイル相当部分５には塗料７が露出し、また、目地相当部分３たる溝部３には目地材９が露出し、以上をもって、目地状模様を有したプレキャストパネル１が完成する。 Then, as shown in FIG. 3D and FIG. 3E, each of the grooves 3, 3,... Is filled with the joint material 9, 9,. It is preferable to use a ridge 33 for filling, and in that case, the joint material 9 is filled while slightly protruding from the groove 3 to the tile-corresponding portion 5, so that the groove 3 can be filled densely. Moreover, according to the ridge 33, the joint material 9 that protrudes from the groove 3 and adheres to the tile-corresponding portion 5 can be easily removed by scraping. The joint material 9 remaining on the tile-corresponding portion 5 is finally wiped off by an appropriate wiping member such as a waste cloth. As a result, the paint 7 is exposed to the tile-corresponding portion 5, and the joint material 9 is exposed to the groove portion 3 which is the joint-corresponding portion 3. Thus, the precast panel 1 having the joint pattern is completed.
＝＝＝第２実施形態＝＝＝
図４Ａ乃至図４Ｄ、及び、図５Ａ乃至図５Ｃは、それぞれ第２実施形態のセメント組成体の製造方法の説明図である。図４Ａ乃至図４Ｄは、セメント組成体が床部の場合であり、図５Ａ乃至図５Ｃは壁部の場合である。何れも斜視図である。
=== Second Embodiment ===
4A to 4D and FIGS. 5A to 5C are explanatory views of the method for producing a cement composition according to the second embodiment, respectively. 4A to 4D show the case where the cement composition is a floor portion, and FIGS. 5A to 5C show the case where it is a wall portion. Both are perspective views.
上述の第１実施形態との相違点は、この第２実施形態に係るセメント組成体が、建物等の施工現場において、現場打ちコンクリートによって製造される点にある。なお、これ以外の点は概ね上述の第１実施形態と同じであり、同じ構成については同じ符号を付し、その説明については省略する。 The difference from the first embodiment described above is that the cement composition according to the second embodiment is manufactured by cast-in-place concrete at a construction site such as a building. The other points are generally the same as those in the first embodiment described above, and the same components are denoted by the same reference numerals and the description thereof is omitted.
施工現場で床部を成形する場合には、先ず、図４Ａに示すように、形成すべき床部の外形形状に対応させて型枠２５を現地で組む。図示例では、型枠２５は、底板２５ａと、底板２５ａの四辺にそれぞれ対応した配された四つの側板２５ｂ，２５ｂ…と、を有している。そして、型枠２５内に配筋し、同型枠２５内に上方から、コンクリート供給管３７を介してコンクリート１Ｃ（セメント流動物に相当）を打設する。 When the floor portion is molded at the construction site, first, as shown in FIG. 4A, the mold 25 is assembled on-site in correspondence with the outer shape of the floor portion to be formed. In the illustrated example, the mold 25 has a bottom plate 25a and four side plates 25b, 25b,... Arranged corresponding to the four sides of the bottom plate 25a. Then, the bar is placed in the mold 25, and concrete 1C (corresponding to a cement fluid) is placed into the mold 25 from above via a concrete supply pipe 37.
次に、図４Ｂのように、打設したコンクリート１Ｃの上面１ｕを鏝等で平坦に均す。そして、この略平坦な上面１ｕが完全に硬化する前に、同上面１ｕに溝部３，３…を形成すべくスタンプ部材３９を押し当てる（図４Ｃ）。このスタンプ部材３９は例えば板材３９ａを本体とし、その板面には、上述のタイル相当部分５の外形形状に対応したロ字状の凸部（不図示）が形成されている。よって、スタンプ部材３９に押し当てられたコンクリート１Ｃの上面１ｕには、図４Ｃのようなタイル相当部分５の外形形状に沿った溝部３，３…が形成され、この押し当て作業を何度か繰り返すことにより、コンクリート１Ｃの上面１ｕには格子状に溝部３，３…が形成される。 Next, as shown in FIG. 4B, the upper surface 1u of the placed concrete 1C is leveled with a scissors or the like. Then, before the substantially flat upper surface 1u is completely cured, the stamp member 39 is pressed against the upper surface 1u to form the grooves 3, 3,... (FIG. 4C). The stamp member 39 has, for example, a plate material 39a as a main body, and has a B-shaped convex portion (not shown) corresponding to the outer shape of the tile-corresponding portion 5 described above. Therefore, on the upper surface 1u of the concrete 1C pressed against the stamp member 39, grooves 3, 3,... Along the outer shape of the tile-corresponding portion 5 as shown in FIG. 4C are formed, and this pressing operation is repeated several times. By repeating, grooves 3, 3,... Are formed in a lattice shape on the upper surface 1u of the concrete 1C.
そして、コンクリート１Ｃの上面１ｕの硬化後に型枠２５を脱型すれば、図４Ｄの床部の本体１ｓが成形される（以上、成形工程に相当）。ちなみに、スタンプ部材３９を用いずに、コンクリート１Ｃの硬化後に、目地切りカッター等で削って溝部３を形成しても良い。 When the mold 25 is removed after the upper surface 1u of the concrete 1C is cured, the floor main body 1s shown in FIG. 4D is formed (this corresponds to the forming step). By the way, without using the stamp member 39, after the concrete 1C is hardened, the groove 3 may be formed by cutting with a joint cutting cutter or the like.
そうしたら、前述の第１実施形態のプレキャストパネル１の場合と同様、図３Ａ乃至図３Ｃに示すように、床部の本体１ｓの上面１ｕを塗料で着色し（塗装工程に相当）、その後に、図３Ｄ及び図３Ｅのように、同上面１ｕの溝部３に充填材９を充填すれば（充填工程に相当）、上面１ｕに目地状模様を有した床部が完成する。 Then, as in the case of the precast panel 1 of the first embodiment described above, as shown in FIGS. 3A to 3C, the upper surface 1u of the main body 1s of the floor portion is colored with paint (corresponding to the painting process), and thereafter As shown in FIGS. 3D and 3E, if the groove 9 on the upper surface 1u is filled with the filler 9 (corresponding to the filling step), a floor portion having a joint pattern on the upper surface 1u is completed.
他方、施工現場で壁部を成形する場合には、以下のようにする。先ず、図５Ａに示すように、形成すべき壁部の外形形状に対応させて各側方に型枠２７の側板２７ｂ，２７ｂ…を現地で組む。ここで、これら側板２７ｂ，２７ｂ…のうちで、溝部３を有した壁面１ｗを形成すべき側板２７ｂにあっては、形成すべき溝部３，３…に対応する各位置に、予め目地棒２３，２３…が格子状に配置されている。また、これと同時又は相前後して型枠２７内に配筋する。そして、図５Ｂに示すように、同型枠２７内に上方からコンクリート１Ｃ（セメント流動物に相当）を打設する。 On the other hand, when the wall is formed at the construction site, the following is performed. First, as shown in FIG. 5A, the side plates 27b, 27b,... Of the mold 27 are assembled locally on each side so as to correspond to the outer shape of the wall portion to be formed. Here, among these side plates 27b, 27b, in the side plate 27b where the wall surface 1w having the groove portion 3 is to be formed, joint rods 23 are previously provided at positions corresponding to the groove portions 3, 3. , 23... Are arranged in a grid pattern. In addition, the bars are arranged in the mold 27 at the same time or in parallel. Then, as shown in FIG. 5B, concrete 1C (corresponding to a cement fluid) is placed in the same mold frame 27 from above.
次に、打設したコンクリート１Ｃの硬化後に型枠２７を脱型し、これにより、図５Ｃの壁部の本体１ｓが成形される。なお、この脱型時には、型枠２７の側板２７ｂの目地棒２３も壁部の本体１ｓから取り外され、これにより、同本体１ｓの壁面１ｗには格子状に溝部３，３…が形成される（以上、成形工程に相当）。 Next, after the cast concrete 1C is hardened, the formwork 27 is removed from the mold, thereby forming the main body 1s of the wall portion in FIG. 5C. At the time of demolding, the joint rod 23 of the side plate 27b of the mold 27 is also removed from the main body 1s of the wall portion, whereby groove portions 3, 3,... Are formed on the wall surface 1w of the main body 1s in a lattice shape. (This corresponds to the molding process).
なお、この例でも、溝部３，３…の形成に目地棒２３，２３…を用いたが、用いずに、目地切りカッター等で壁面１ｗを削って溝部３，３…を形成しても良いのは、前述の第１実施形態の場合と同様である。 In this example, the joint rods 23, 23,... Are used to form the grooves 3, 3,..., But the wall portions 1w may be shaved with a joint cutter or the like to form the grooves 3, 3,. This is the same as in the case of the first embodiment described above.
そうしたら、前述の第１実施形態のプレキャストパネル１の場合と同様、図３Ｂ及び図３Ｃに示すように、溝部３が形成された壁面１ｗを塗料で着色し（塗装工程に相当）、その後に、同壁面１ｗの溝部３に充填材９を充填すれば（充填工程に相当）、壁面１ｗに目地状模様を有した壁部が完成する。ちなみに、この壁部の場合には、図３乃至図３Ｅ中の左右方向が、実際の上下方向（鉛直方向）に対応している。 Then, as in the case of the precast panel 1 of the first embodiment described above, as shown in FIGS. 3B and 3C, the wall surface 1w on which the groove 3 is formed is colored with paint (corresponding to the painting process), and then If the groove portion 3 of the wall surface 1w is filled with the filler 9 (corresponding to the filling step), the wall portion having the joint pattern on the wall surface 1w is completed. Incidentally, in the case of this wall, the horizontal direction in FIGS. 3 to 3E corresponds to the actual vertical direction (vertical direction).
