1. المواصفات الفنية لمواد التسقيف ومتطلبات بيئة العمل

تُستخدم لفائف الأغشية البيتومينية البوليمرية ذات الأساس من الألياف الزجاجية أو البوليستر كمادة عزل مائي أساسية. للطبقة العلوية من فرش السقف، تُستخدم مادة بكثافة سطحية تتراوح من 4.2 إلى 4.8 كجم/م² وقوة شد عند الكسر لا تقل عن 490 نيوتن (على أساس قماش الألياف الزجاجية) أو 590 نيوتن (على أساس نسيج البوليستر). للطبقة السفلية، تُستخدم غشية بكثافة تتراوح من 3.4 إلى 3.8 كجم/م². يجب أن لا تقل الكثافة السطحية للمادة الرابطة البيتومينية البوليمرية على الجانب القابل للحام بدقة عن 2.0±0.3 كجم/م².

تتضمن طريقة التركيب بدون لهب لصق طبقة اللفائف عن طريق إذابة الطبقة السفلية من المادة الرابطة. لهذا الغرض، يُستخدم برايمر يتكون من بيتومين إنشائي درجة 70/30، مخفف بالكيروسين أو الوايت سبيريت بنسبة 1:3 بالوزن بدقة. تسمح هذه التقنية بتنفيذ الأعمال خلال فصلي الصيف والشتاء على قواعد صلبة (بلاطات خرسانية مسلحة، مونة أسمنتية رملية، أو طبقات تسوية أسفلتية).

تُنفذ الأعمال في وردية واحدة بواسطة فريق مؤهل من فنيي عزل الأسقف. عند العمل في الظروف الشتوية أو في درجات حرارة متجمدة، يجب تكييف المواد الملفوفة مسبقًا في غرفة دافئة. يزيل استخدام الطريقة عديمة اللهب الحاجة إلى استخدام اللهب المكشوف، وهو أمر بالغ الأهمية في المنشآت ذات متطلبات السلامة من الحرائق العالية.

2. إعداد الركيزة الحاملة وتركيب حاجز البخار

تعمل ألواح الخرسانة المسلحة كقاعدة حاملة للسقف؛ يجب أن يتم حشو الفواصل بينها إلزامياً بمونة أسمنتية رملية بقوة ضغط لا تقل عن 10 ميجا باسكال أو خرسانة ناعمة من فئة C8/10 (B8.5). يُسمح أيضًا باستخدام ألواح أسمنت الأسبستوس المسطحة أو ألواح الجسيمات المربوطة بالأسمنت بسمك 10 مم كطبقة تسوية مسبقة الصنع. لمنع التواء الألواح، يتم تأسيسها من كلا الجانبين، وتوضع شرائط بعرض 100 مم تحت فواصل الألواح المتجاورة.

لحماية العزل الحراري من انتشار بخار الماء من المساحات الداخلية، يتم تركيب حاجز بخار فوق الهيكل الحامل. قبل وضعه، يتم تنظيف السطح الخرساني من اللباني الأسمنتي، وإزالة الغبار عنه بواسطة ضواغط صناعية، وتجفيفه. يُصنع حاجز البخار المطلي من ماستيكات بوليمرية بيتومينية باردة أو ورنيشات مطاط كلوريني. يتم تركيب حاجز البخار الملصق من غشاء بولي إيثيلين بسمك لا يقل عن 200 ميكرومتر أو مواد مغلفة بالرقائق مع إغلاق إلزامي للتداخلات.

من المعلمات الحاسمة في هذه المرحلة هو استواء القاعدة. يتم فحص التفاوتات باستخدام مسطرة مستقيمة قياسية بطول ثلاثة أمتار: يجب ألا تتجاوز الفجوات 5 مم عند وضع المسطرة على طول الميل و10 مم عند وضعها عرضياً. لا يُسمح بأكثر من فجوة واحدة ذات شكل ناعم لكل متر من طول المسطرة. النتوءات الحادة وفروق الارتفاع عند فواصل البلاطات التي تتجاوز 5 مم تخضع للتسوية الإلزامية.

3. تقنية مد مواد العزل الحراري

يجب أن تتمتع مواد العزل الحراري الصلبة على شكل ألواح بقوة ضغط عند تشوه بنسبة 10% لا تقل عن 0.06 ميجا باسكال وأن تكون مقاومة للمذيبات. تُوضع الألواح في طبقة واحدة أو عدة طبقات. في التركيب متعدد الطبقات، تكون فواصل الطبقة العلوية متخالفة بالنسبة لفواصل الطبقة السفلية للقضاء على الجسور الحرارية. يتم الالتصاق باستخدام ماستيك بيتوميني ساخن (نقطة تليين 75-80 درجة مئوية)، يُطبق على شكل شرائط بعرض 20 سم بمسافة بينية 40-50 سم.

لضمان تصريف فعال، يتم الحفاظ بدقة على الميول التصميمية. في المزاريب، يتشكل الميل ضمن 1-3%. حول قمعات تصريف السطح الداخلية، على مسافة 0.5-1.0 م، يزداد الميل بشكل مصطنع إلى 5-10% لإنشاء وعاء استقبال بقطر حوالي 1 م وعمق 5-10 سم. عند الأجزاء المتدلية من الأفاريز (على مسافة 0.2-0.5 م من الحافة)، ومع ميول السقف الطفيفة، يزداد الميل المحلي إلى 25% كحد أدنى.

تُورد مواد العزل السائب (الركام الطيني الخفيف، البيرلايت) بواسطة التركيبات الهوائية وتُرصف في طبقات لا يزيد سمكها عن 10 سم على طول قضبان توجيه طبقة التسوية مع دك شامل. يُوضع العزل الحراري المتراص المصنوع من الخرسانة الخفيفة في شرائط متناوبة بعرض 4-8 أمتار، مع قطع فواصل تمدد عرضية بعرض 15-20 ملم كل 2-6 أمتار. يُسمح بصب الخرسانة للعزل المتراص فقط عند درجات حرارة هواء خارجية لا تقل عن +5 درجات مئوية.

4. تركيب مونة التسوية وفواصل التمدد والانكماش

فوق عزل الألواح أو الخرسانة الخفيفة المتراصة، تُطبق طبقة تسوية من المونة الأسمنتية الرملية بسمك 15 ملم. يجب أن لا تقل مقاومة الضغط للمونة عن 5 ميجا باسكال (رتبة M50). عند تنفيذ الأعمال في الظروف الشتوية، تُستخدم مونة بمقاومة 10 ميجا باسكال (M100) باستخدام رمل الركام الطيني الخفيف وإضافة البوتاس بكمية 10-15% من كتلة الإسمنت. يجب أن تكون درجة حرارة ماء الخلط في هذه الحالة +30 درجة مئوية، مما يسمح بإجراء العمل في درجات حرارة هواء تصل إلى -33 درجة مئوية.

في فترة الخريف والشتاء، يُسمح بتركيب طبقات تسوية بسمك 15-30 ملم من الخرسانة الإسفلتية الرملية بمقاومة ضغط لا تقل عن 0.8 ميجا باسكال (عند درجة حرارة 50 درجة مئوية). فوق القواعد الصلبة، يكون السمك 15-20 ملم، وفوق القواعد غير الصلبة — 20-30 ملم. تُوضع الخرسانة الإسفلتية على طول قضبان التوجيه في شرائط بعرض 2-3 أمتار وتُدمك بمدحل يدوية بوزن 80-100 كجم. من المهم ملاحظة أن تركيب طبقات التسوية من الخرسانة الإسفلتية ممنوع منعًا باتًا فوق العزل السائب وعلى المنحدرات التي تتجاوز 20-25% بسبب خطر الانزلاق تحت تأثير درجات حرارة الصيف.

لمنع التشققات في طبقات التسوية، يُلزم قطع فواصل تمدد وانكماش بعرض يصل إلى 5 ملم. تُقسّم هذه الفواصل طبقات التسوية الأسمنتية الرملية إلى أقسام لا تزيد عن 6x6 متر، وطبقات التسوية الخرسانية الإسفلتية — لا تزيد عن 4x4 متر. في أرضيات الأسقف المصنوعة من الألواح مسبقة الصب، يُخفض حجم القسم إلى 3x3 متر. يجب أن تتطابق الفواصل تمامًا مع فواصل النهايات للألواح الحاملة. فوق الفواصل، تُوضع شرائط من المواد اللفائفية بعرض 150 ملم مع التصاق موضعي على جانب واحد فقط من الفصل.

5. تجهيز الأساس بالبرايمر وتركيب الزوايا الانتقالية (المشطوفات)

عند تقاطعات السقف مع الهياكل العمودية (الستائر، الجدران، فتحات التهوية)، تُعتبر الحليات الانتقالية (الزوايا المائلة) المصنوعة من المونة الأسمنتية الرملية إلزامية. يجب ألا يقل ارتفاع الحلية عن 100 ملم. تُنفذ إما بزاوية 45 درجة (ميل 100%) أو كمنحنى أملس بنصف قطر 100-150 ملم. يمنع هذا تمزق المواد اللفائفية عند الانتقال من مستوى أفقي إلى مستوى عمودي.

مباشرة بعد وضع طبقة التسوية الأسمنتية الرملية الطازجة، يُطلى سطحها بطبقة أساس من محلول بيتومين درجة 90/10 في مذيب بطيء التبخر (زيت الديزل/السولار) بنسبة 1:2 أو 1:3. يبلغ استهلاك هذه الطبقة الأساس 0.2 كجم/م². يسمح التطبيق على المونة الطازجة للطبقة الأساس بالتغلغل بعمق في المسام، وتحمي الطبقة الناتجة طبقة التسوية من التبخر المبكر للرطوبة، لتحل محل معالجة الخرسانة. عند تحضير قواعد الخرسانة الإسفلتية، يُستخدم بيتومين 70/30 باستهلاك 0.8-1.0 كجم/م².

يتم تحضير الأسطح العمودية (الجدران، الستائر، الأنابيب) إلى ارتفاع 150-350 ملم من مستوى السقف، حسب المنطقة المناخية. عند هذا الارتفاع، تُثبت عارضة خشبية مطهرة مقاس 40x60 ملم في مجرى لتثبيت حافة طبقة العزل المائي للسطح ميكانيكيًا. تُسوّى السطح أسفل التقاطع بطبقة من المونة الأسمنتية الرملية (بقوة 10 ميجا باسكال) بسمك 10-15 ملم بمحاذاة العارضة المثبتة.

6. ضبط جودة الأساس وتركيب طبقة التسقيف باللفائف

قبل بدء تركيب طبقة العزل المائي للسطح، يتم استلام دقيق بالأجهزة للقاعدة. يتم التحقق من مطابقة الميول التصميمية من فواصل المياه إلى مصارف تصريف السطح. إن وجود ميول عكسية ممنوع منعًا باتًا، لأنه حتى مع ميل 1-3%، فإن أدنى تفاوت سيؤدي إلى ركود المياه. في الوديان، يتم فحص الاستواء باستخدام خيط مشدود بإحكام بين المصارف — يجب ألا تتجاوز المسافة من الخيط إلى قاع الوادي 5 ملم.

يبدأ التصاق غشاء العزل الملفوف بالطريقة غير اللهبية فقط بعد أن يجف السطح التمهيدي تمامًا (يتم التحقق من عدم لزوجته 'tack-free'). يتم فرد اللفائف ولصقها باستخدام مذيب يعمل على تليين الطبقة السفلية البوليمرية-البيتومينية للغشاء. لضمان التصاق موثوق وإزالة فقاعات الهواء، تُستخدم معدات احترافية: بكرات ضغط ثقيلة (قوة 70-150 نيوتن، عرض الشريط يصل إلى 150 ملم). تم تجهيز البكرة بنظام موازنة يسمح بالتكيف مع الانحرافات السطحية الطفيفة.

يتم تعزيز بروزات الأفاريز ذات التصريف الحر للمياه بشكل إضافي. يتم لف حافة مادة اللفائف حول البروز، وتُثبت بمسامير في لوح خشبي مدمج، وتُنهى بفولاذ تسقيف مجلفن (حافة تنقيط). تُثنى حواف التنقيط للتشطيب الفولاذي بعيدًا عن الأفريز بمسافة لا تقل عن 30 ملم. تُلصق الطبقة العلوية من غشاء السقف المصنوعة من مادة ذات تكسية أردوازية واقية بإزاحة للفواصل الطولية والعرضية بالنسبة للطبقة السفلية، وذلك وفقًا للوائح الفنية للمصنع.

Tips & Recommendations
!
يُحظر منعًا باتًا التلامس المباشر لألواح العزل الحراري من رغوة الفينول-فورمالدهيد (نوع ريزول) مع ألواح التغطية الفولاذية المضلعة، وذلك نظرًا لارتفاع خطر تآكل المعادن.
i
عند تركيب ألواح الصوف المعدني عالية الصلابة، يحظر استخدام المعدات ذات العجلات على السطح. ويجب أن يتم تركيب العزل والطبقة السفلية للعزل المائي بدقة في وردية عمل واحدة.
!
لا تستخدم طبقات التسوية من الخرسانة الإسفلتية على المنحدرات التي تزيد عن 20% وفوق العزل الحراري السائب. ففي ظل تأثير درجات الحرارة الصيفية المرتفعة، هناك خطر كبير لهبوط وانزلاق نظام السقف الساندويتش.
i
عند تحضير طبقة تسوية أسمنتية رملية حديثة الوضع، استخدم برايمر بيتوميني يعتمد على مذيب بطيء التبخر (السولار). سيحجب غشاء البرايمر تبخر الماء، مما يوفر ظروفًا مثلى لاكتساب الخرسانة قوتها.
!
في الأودية والمزاريب، لا يتم وضع طبقة العزل الحراري. هذا الحل التصميمي ضروري لإنشاء منطقة لذوبان مكثف للثلج والجليد بسبب انبعاثات الحرارة من المبنى.
