Abstract
Description
本発明は、高断熱性と美観性を兼ね備えた外断熱装飾仕上げ工法および壁面構造体に関するものである。 The present invention relates to an outer heat insulating decorative finishing method and a wall structure having both high heat insulating properties and aesthetics.
近年、商業施設、集合住宅、戸建住宅等の建築物においては、高断熱化・高気密化によって、冷暖房費の節約を図り、省エネルギー化、省資源化を実現しようとする動きが盛んである。
一般に、断熱設計を施していない建築物では、冬期の暖房時には屋根、床、窓、壁等の部位から室内の熱が逃げ、夏期の冷房時にはこれら部位から屋外の熱が侵入してしまう。このような熱損失の約３分の１は壁面に起因すると言われている。そのため、建築物の省資源化を実現するには、室内と屋外を隔てる外壁の高断熱化が不可欠であり、外壁表面に断熱性材料を設けた壁面構造が種々提案されている。一例として、建築物外壁表面に、ポリスチレンフォームやフェノールフォーム等による断熱材層を設け、さらに塗膜を設けた壁面構造が知られている（例えば特許文献１等）。
しかしながら、このような壁面構造は、単調な色調のものが殆どであり、意匠性には乏しいのが現状である。
In recent years, in buildings such as commercial facilities, apartment houses, and detached houses, there has been a lot of efforts to save energy and resources by saving air conditioning costs through high insulation and high airtightness. .
In general, in a building not designed for heat insulation, indoor heat escapes from the roof, floor, window, wall, and other parts during heating in the winter, and outdoor heat enters through these parts during cooling in the summer. It is said that about one third of such heat loss is caused by the wall surface. Therefore, in order to realize resource saving of buildings, it is indispensable to increase the heat insulation of the outer wall that separates the room from the outside, and various wall structures in which a heat insulating material is provided on the outer wall surface have been proposed. As an example, a wall surface structure in which a heat insulating material layer made of polystyrene foam, phenol foam, or the like is provided on the outer wall surface of a building and a coating film is further provided is known (for example, Patent Document 1).
However, such wall structures are mostly monotonous in color tone and have a poor design.
本発明は、上述のような問題点に鑑みなされたもので、建築物外壁に断熱材を設け、高断熱化を図るとともに、その壁面の美観性を高めることを目的とするものである。 The present invention has been made in view of the above-described problems. It is an object of the present invention to provide a heat insulating material on a building outer wall to increase heat insulation and to enhance the aesthetics of the wall surface.
本発明者は、上記目的を達成するため鋭意検討を行った結果、建築物外壁面の壁体材料上の外断熱構造基材に対し、特定の態様で装飾性塗材層を設けることに想到し、本発明を完成させるに到った。 As a result of earnest studies to achieve the above object, the present inventor has conceived that a decorative coating material layer is provided in a specific manner on an outer heat insulating structure base material on a wall material of a building outer wall surface. The present invention has been completed.
すなわち、本発明は以下の特徴を有するものである。
１．建築物外壁面の構造体であって、
壁体材料と、該壁体材料上に設けられた断熱材層とからなる外断熱構造基材に対し、
下塗材層、装飾性塗材層が積層され、
装飾性塗材層は目地により区画されている外断熱装飾仕上げ構造体。
２．前記外断熱構造基材は補強層を有し、該補強層は断熱材層上に設けられ、
該補強層は、ポリマーセメント層及び／または網状体からなるものである１．記載の外断熱装飾仕上げ構造体。
３．（Ａ）建築物外壁面の壁体材料上に、断熱材層が積層された外断熱構造基材に対し、下塗材を塗付して下塗材層を形成する工程、
（Ｂ）該下塗材層の表面に目地材を貼着する工程、
（Ｃ）（Ｂ）で得られた表面に装飾性塗材を塗付する工程、
（Ｄ）目地材の一部または全部を脱着する工程、
を含む外断熱装飾仕上げ工法。
４．断熱材層上に補強層が設けられ、該補強層は、ポリマーセメント層及び／または網状体からなるものである３．記載の外断熱装飾仕上げ工法。
That is, the present invention has the following characteristics.
1. A structure of an outer wall surface of a building,
For an outer heat insulating structure base material composed of a wall body material and a heat insulating material layer provided on the wall body material,
A primer layer and a decorative coating layer are laminated,

試験例１〜６で作製した壁面構造体の一部を取り出し、試験体（６０×４０ｍｍ）とし、次の試験を行った。 A part of the wall surface structure produced in Test Examples 1 to 6 was taken out and used as a test body (60 × 40 mm), and the following test was performed.
・耐候性試験
耐候性試験は、促進耐候性試験機「メタルウェザー」（ダイプラ・ウィンテス株式会社製）を用い、光照射４時間・結露４時間（計８時間）を１サイクルとして８０サイクルまで実施した。評価は、８０サイクル後の塗膜外観を観察し、異常が認められなかったものを「Ａ」、色変化、膨れ、剥れ等が認められたものを「Ｃ」とする３段階（Ａ＞Ｂ＞Ｃ）で行った。試験結果を表１に示す。
・ Weather resistance test For the weather resistance test, an accelerated weather resistance tester "Metal Weather" (manufactured by Daipura Wintes Co., Ltd.) is used, and light irradiation is 4 hours and condensation is 4 hours (total 8 hours). did. The evaluation was made in three stages (A>, where the appearance of the coating film after 80 cycles was observed, with “A” indicating no abnormality and “C” indicating color change, swelling, peeling, etc. B> C). The test results are shown in Table 1.
・追従性試験
追従性試験では、試験体（３００×１５０ｍｍ）につき、水浸漬（２３℃）１８時間→−２０℃３時間→８０℃３時間を１サイクルとする温冷繰返し試験を合計１０サイクル行った後、試験体表面の状態を観察した。評価は、異常が認められなかったものを「Ａ」、膨れ、剥れ等が認められたものを「Ｃ」とする３段階（Ａ＞Ｂ＞Ｃ）で行った。試験結果を表１に示す。
・ Followability test In the followability test, a test sample (300 × 150 mm) is subjected to water-cooled (23 ° C.) 18 hours → -20 ° C. 3 hours → 80 ° C. 3 hours as one cycle for a total of 10 cycles. After the test, the state of the specimen surface was observed. The evaluation was performed in three stages (A>B> C) where “A” indicates that no abnormality was observed and “C” indicates that swelling or peeling was observed. The test results are shown in Table 1.
・密着性試験
密着性試験では、試験体を５０℃の温水に６時間浸漬した後、試験体中央部の塗膜（装飾性塗材部）にカッターナイフでクロスカットを入れ、このクロスカット部分にテープを貼り付けて剥ぐことにより密着性を評価した。評価は、異常が認められなかったものを「Ａ」、剥れが認められたものを「Ｃ」とする３段階（Ａ＞Ｂ＞Ｃ）で行った。試験結果を表１に示す。
・ Adhesion test In the adhesion test, after immersing the specimen in warm water at 50 ° C for 6 hours, a crosscut was made with a cutter knife in the coating film (decorative coating material part) at the center of the specimen. Adhesion was evaluated by applying a tape to the film and peeling it off. The evaluation was performed in three stages (A>B> C) where “A” indicates that no abnormality was observed and “C” indicates that peeling was observed. The test results are shown in Table 1.
