濟南抹面砂漿廠家告訴您砂漿開裂的原因

來源：http://www.wavc.cn 日期：2020-05-19 發布人：

　　下面就濟南抹面砂漿施工中導致外墻保溫系統抹灰砂漿層裂縫的施工因素進行分析。

　　Next, the paper analyzes the construction factors that cause the cracks in the plastering mortar layer of the external wall insulation system in the plastering mortar construction of Jinan.

　　外墻外保溫系統在本工程施工現場完成。抹面砂漿的質量關系到保溫系統的整體質量，也是導致保溫抹灰砂漿層開裂的重要因素。

　　The external wall external insulation system shall be completed at the construction site of the project. The quality of plastering mortar is related to the overall quality of the insulation system, and it is also an important factor leading to the cracking of the insulation plastering mortar layer.

　　1. 基礎面平整度偏差過大，調整粘結劑厚度、調整多層板、調整表面拋光、調平等，都會導致保溫質量的質量缺陷。

　　1. If the flatness deviation of the foundation surface is too large, adjusting the thickness of the binder, adjusting the multi-layer plate, adjusting the surface polishing, and adjusting the equality will lead to the quality defects of the insulation quality.

　　2、基層表面含有粉塵等阻礙膏體的物質，膏體制作時未進行界面處理。

　　2、 The surface of the base layer contains dust and other substances that hinder the paste, and the interface treatment is not carried out when the paste is made.

　　3.濟南粘接砂漿介紹保溫板粘接面積太小，不符合規范和施工方案的要求，不能滿足粘接面積的質量要求。

　　3. Jinan bonding mortar introduces that the bonding area of insulation board is too small, which does not meet the requirements of specifications and construction scheme, and cannot meet the quality requirements of bonding area.

　　4. 保溫板的埋深和錨釘數量不符合設計和施工方案的要求。

　　4. The buried depth of the insulation board and the number of anchor nails do not meet the requirements of the design and construction scheme.

　　5. 耐堿性玻璃纖維網格布的研磨寬度不符合規范要求，研磨處產生裂紋。

　　5. The grinding width of alkali resistant glass fiber mesh does not meet the specification requirements, and cracks are produced at the grinding place.

　　6. 門窗開口的四個角是應力集中的地方。沿門窗開口45°方向不加耐堿玻纖網布，經常出現裂縫。

　　6. The four corners of the door and window opening are the places where the stress is concentrated. Along the 45 ° direction of the door and window opening, alkali resistant glass fiber mesh is not added, and cracks often occur.

　　7. 在太陽暴曬或高溫天氣下施工抹灰砂漿層，保水性能不足，導致抹灰砂漿層失水過多而產生裂縫。

　　7. When the plastering mortar layer is constructed in the sun or high temperature weather, the water retention performance is insufficient, resulting in excessive water loss of the plastering mortar layer and cracks.

　　濟南抹面砂漿介紹了導致外墻保溫系統抹灰砂漿層裂縫預防措施的材料因素

　　Jinan plastering mortar introduces the material factors that cause the cracks in the plastering mortar layer of the external wall insulation system

　　1、圖紙設計選擇密度18 - 22公斤/立方米保溫板,材料的批準由國家檢驗機構檢驗合格,保溫材料進入現場測量后質量檢查的密度,在施工的過程中檢查或定期聚苯板測量密度,防止施工單位在施工過程中以次充好的行為。

　　1. The density of 18-22kg / m3 insulation board is selected in the drawing design. The approval of the material is inspected and qualified by the national inspection agency. The density of the quality inspection after the insulation material enters the site for measurement. During the construction process, check or regularly measure the density of polystyrene board to prevent the construction unit from shoddy behavior in the construction process.

　　2. 保溫材料應由系統材料供應商配套供應，更好地發揮粘結劑、保溫板、耐堿玻璃纖維網布、抹灰砂漿的整體效果。

　　2. The thermal insulation material shall be supplied by the system material supplier to give full play to the overall effect of binder, thermal insulation board, alkali resistant glass fiber mesh and plastering mortar.

　　3、濟南抹面砂漿告訴你選擇正常施工企業綜合實力盡可能開發人員可以支付預付款prematerial,建設單位建議需要提前定制保溫板,為了確保保溫板保溫施工前有足夠的老化時間,防止墻后的保溫板繼續萎縮。

　　3. Jinan plastering mortar tells you to choose the normal construction enterprise's comprehensive strength as much as possible, the developer can pay the advance payment, the construction unit must customize the insulation board in advance, in order to ensure that the insulation board has enough aging time before construction, to prevent the insulation board behind the wall from shrinking.

　　4、將聚苯乙烯板糊固定好后，其糊強度要滿足要求，及時做好表面層，避免因曝光時間過長而引起的板面溫度過高。

　　4. After the polystyrene board paste is fixed, the paste strength shall meet the requirements, and the surface layer shall be prepared in time to avoid the board temperature caused by too long exposure time.

　　5. 基礎與粘結劑的抗拉結合強度不低于0.3mpa，結合界面分離面積不大于50%。

　　5. The tensile bond strength of foundation and binder shall not be less than 0.3mpa The separation area of the interface shall not be greater than 50%.

　　6. 外墻保溫系統的材料應符合《發泡聚苯板薄抹灰外墻保溫系統》、《外墻保溫工程技術規程》等相關行業標準的要求。

　　6. The materials of external wall insulation system shall meet the requirements of relevant industry standards such as foamed polystyrene board thin plastering external wall insulation system, technical specification for external wall insulation engineering, etc.
