一、巖棉復(fù)合板保溫層與結(jié)構(gòu)層以及保溫層與保護(hù)層的連接方式。
A composite rock wool insulation layer and structure layer and the insulation layer and protective layer connection.
保溫層、保護(hù)層與結(jié)構(gòu)層的連接方式，目前有以下幾種：連桿托架；斜連桿托架；長螺桿；黏結(jié)劑。上述4種連接方式各有特點(diǎn)，但綜合比較，前3種施工比較麻煩而第四種方案還涉及黏結(jié)強(qiáng)度和耐久性等問題，為此建議采用以下4種更為簡便的方案：射釘方案；膨脹螺栓方案；預(yù)埋鋼筋或塑料筋方案；黏、釘結(jié)合方案。這幾種方案不僅施工方便，而且也有較好的耐久性。
Insulation layer, protective layer and structure layer connection mode, at present there are the following: connecting rod bracket; inclined connecting rod bracket; long screw; binder. The above 4 kinds of connections with different characteristics, but the comprehensive comparison, the former 3 kinds of complicated construction and fourth kinds of programs also involve the bond strength and durability, therefore recommend the following 4 more simple solution: nail scheme; expansion bolt scheme; embedded steel or plastic clay, nail reinforcement scheme; combined with the project. These schemes are not only easy to be used in construction, but also have good durability.
二、巖棉復(fù)合板防止和消除保護(hù)層和飾面層出現(xiàn)裂縫，研究減少保護(hù)層應(yīng)力集中和收縮應(yīng)力的措施。
Two, rock wool composite panels to prevent and remove the protective layer and the surface layer cracks, reduce the stress concentration and the shrinkage stress protective measures.
保護(hù)層和飾面層出現(xiàn)裂縫主要有如下幾種原因：
There are several reasons for the cracks in the protective layer and the facing layer:
①保護(hù)層與保溫層的黏結(jié)強(qiáng)度較低或出現(xiàn)空鼓；
The bonding strength of the protective layer and the insulating layer is low or konggu;
②保護(hù)層和飾面層收縮變形較大，導(dǎo)致產(chǎn)生裂縫；
The protective layer and the facing layer shrink deformation, leading to crack;
③由于門窗洞口處應(yīng)力集中，導(dǎo)致保護(hù)層和飾面層出現(xiàn)裂縫。
Due to the stress concentration at the door and window of the door and window, the protective layer and the facing layer appear cracks.
針對上述產(chǎn)生裂縫的幾種主要原因，宜采取以下幾種防裂措施：
Aiming at several main cause of the cracks, should take the following measures for crack prevention:
①采用鋼絲網(wǎng)或采用鋼絲網(wǎng)夾心巖棉板增強(qiáng)層，一方面鋼絲網(wǎng)可以增強(qiáng)結(jié)構(gòu)層與保溫層和保護(hù)層的連接，另一方面還可以分散保護(hù)層和飾面層的收縮應(yīng)力和應(yīng)力集中，從而達(dá)到減少和防止出現(xiàn)裂縫的目的。在墻體容易產(chǎn)生裂縫的部位還需采取局部設(shè)置加強(qiáng)網(wǎng)措施。
The steel wire mesh or steel wire mesh sandwich rockwool board reinforced layer, a wire mesh can enhance the structure layer and the insulation connecting layer and a protective layer, on the other hand can also disperse the protective layer and the surface layer of shrinkage stress and stress concentration, so as to reduce and prevent the emergence of crack to. In the wall prone to cracks in the part of the need to take local settings to strengthen network measures.
②采用黏結(jié)強(qiáng)度較高、收縮變形小且具有一定彈性的微膨脹防裂砂漿或聚合砂漿。由于巖棉板質(zhì)地較軟，故防裂砂漿厚度以25mm~30mm為宜。
The bond strength is high, small shrinkage, and has a certain elasticity of expansive mortar cracking or polymer mortar. The rock wool board with soft texture, so the thickness of mortar cracking should be 25mm~30mm.
③將保護(hù)層進(jìn)行分塊留縫并做好嵌縫防水處理，以便減少收縮和溫度應(yīng)力。
The protective layer block seam and good sealing waterproofing treatment, in order to reduce the shrinkage and temperature stress.
三、巖棉復(fù)合板解決好保護(hù)層與飾面層的耐候性問題。
Good protection of the weathering layer and the surface layer three, rock wool composite panels.
解決好保護(hù)層與飾面層耐候性可以采用兩種方法：
Two methods can be used to solve the weather resistance of the protective layer and the facing layer:
①在保護(hù)層外貼飾面磚，但此方法增加了墻體自重和造價(jià)，做為有較高裝飾要求的建筑還是可行的。
The outside of the protective layer face tiles, but this method increases the wall weight and cost, as the higher requirements of the building decoration is feasible.
②在保護(hù)層外邊噴涂高彈性、耐候性好的外墻涂料，由于這種涂料既有較好的彈塑性和防水功能，又有較好的防裂和耐候性能，故對保護(hù)層和保溫層都起到了保護(hù)作用。
The protective layer outside coating with high elasticity, good weather resistant exterior wall paint, because the paint has good plasticity and waterproof function, but also has better crack resistance and weather resistance, so the protective layer and the insulation layer plays a protective role.
