本発明は、コンクリート、プレハブ等の建築物特に老朽
ビル等の外壁外装の改装に使用して便なる外装材及びそ
の施工方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an exterior material made of concrete, prefabricated materials, etc., which can be conveniently used for renovating the exterior walls of buildings, particularly old buildings, and a method for constructing the same.
タイルやモルタル製のビルの外壁は建築後20年程度以
上経つと、塵埃で汚くなったりはがれ落ちる危険性があ
り、現に落下事故が社会問題にもなっている。Building exterior walls made of tiles and mortar are at risk of becoming dirty with dust or peeling off more than 20 years after construction, and falling accidents have become a social problem.
昭和30年代以降のビル建設ラッシュ時に完成したビル
は、これから本格的な改装時期を迎えることになり、外
壁外装の需要は逐次多大なものとなっている。Buildings that were completed during the building construction boom that began in the 1950s are about to enter the period of full-scale renovation, and the demand for exterior walls is increasing one by one.
ところが、外壁外装の代表的な従来法である吹き付は塗

の仕上げ材等に吹き付は剤が飛んで汚染されないように
ビニールシー1〜、紙等をテープで張って養生する必要
もある。However, in the case of painting, spraying, which is a typical conventional method for exterior walls, prepares the base by applying cement paste containing a synthetic resin emulsion or cement-based filler (ready-mixed base conditioning material), especially for exterior walls. Where there were cracks, distortions, or irregularities, adhesive-containing perlite mortar was applied evenly with a metal trowel, and then the finish was brushed off. Before spraying after preparing the base, the outer surface of the scaffold must be covered with a sheet to protect it from direct sunlight, wind, rain, etc. In addition, when spraying on uprights, openings, other finishing materials, etc., it is necessary to cure them by covering them with vinyl sheets, paper, etc. with tape to prevent the spray agent from flying off and contaminating them.
下地処理後は、充分な乾燥(モルタル下地では14日以

が用いられている。After the surface treatment, sufficient drying (more than 14 days for mortar bases) was confirmed, and the finish was completed by performing two operations, bottom blowing and top blowing, using a pressure-feed blower or the like. Usually, the bottom spray material does not contain a waterproofing agent, the top spray material contains a waterproofing agent, and a finishing agent is used for spraying to give water repellency.
以上述べたように吹き付は塗装では、前記養生の他吹き

ればならない他、色むら・吹きむら等吹き付は塗装を行
なうにはかなりの熟練を要し、施工時期や施工箇所周辺
に様々な注意を払わなければならない。As mentioned above, in spray painting, in addition to the above-mentioned curing, it is necessary to take thorough care to prevent the spray agent from scattering far and coming into contact with neighbors, passersby, cars, etc. Furthermore, since efflorescence may occur when painting in the winter, it is necessary to choose a warm day to apply the paint when it is cold. It requires skill, and various precautions must be taken regarding the construction period and surrounding areas.
タイル施工の場合、モルタルで下地塗りを行ない、接着
セメントを混練して、櫛目付き平ごてて塗着する。そし

条件に応じて適宜小さくする。In the case of tile construction, the base coat is applied with mortar, the adhesive cement is kneaded and applied with a combed flat trowel. Then, tap the tiles lightly with a mallet to blend them well and align them flat. The amount of adhesive cement to be used within about one hour is kneaded and mixed, and the area of one application is limited to about 2M, with the area reduced as appropriate depending on weather conditions.
また、タイルを固定するためにセメント粉を振りかけ、
モルタルを急結させると、後日目地の切れ目から入った
雨水に熔けて濃厚なアルカリ液となり、下方の目地から
流れ出してタイル面が白く汚れることがある。Also sprinkle cement powder to fix the tiles,
If the mortar is allowed to set too quickly, it will later dissolve into rainwater that enters through the joint cuts, forming a thick alkaline solution that may flow out from the joints below, staining the tile surface white.
このように、タイル張り外壁ではタイル裏面に隙間が生
したり、タイルのねじれや目違い等が生したすしないよ
うに細心の注意を払う必要があり工事期間はもとより工
事費等が増加するという欠点を有するものであった。In this way, with tiled exterior walls, great care must be taken to prevent gaps from forming on the back of the tiles, twisting or misalignment of tiles, etc., which increases not only the construction period but also construction costs. It had some drawbacks.
