Steel space grid gas station project construction

هذا المشروع عبارة عن اطار فضاء مربع / ارتفاع 16 متر / اجمالي طول 30 متر / اجمالي امتداد 18 متر

1. يجب أن يتم تركيب إطار الفضاء الفولاذي بعد قبول محور الهيكل السفلي واللوحة المدمجة.متطلبات الدعم السفلي هي: فرق الارتفاع بين الدعامات المجاورة (المسافة L2): القيمة الأصغر من L2 / 800 و 10 مم ، عند نفس الارتفاع ، فرق الارتفاع بين أعلى وأقل دعم: 20 مم ؛

2. تحديد عملية تركيب إطار الفضاء الفولاذي وفقًا للقوة والخصائص الهيكلية للشبكة وظروف البناء الفعلية في الموقع ؛

3. بعد تركيب إطار الفضاء الفولاذي ، يجب فحصه:

أ.القيمة المسموح بها لانحراف طول الجانب الرأسي والأفقي هي 1/2000 من الطول ، ويجب ألا تكون أكبر من 30 مم ؛

ب.يجب أن تكون القيمة المسموح بها لإزاحة المركز 1/3000 من امتداد إطار الفضاء الفولاذي ، ويجب ألا تزيد عن 30 مم ؛

ج.بالنسبة لإطار الشبكة الذي يدعمه المحيط ، يكون انحراف الارتفاع المسموح به هو 1/400 من الدعم المجاور ، ويجب ألا يكون أكبر من 15 مم ، ويجب ألا يزيد الحد الأقصى والحد الأدنى عن 30 مم ؛بالنسبة لإطار الشبكة المدعوم بنقاط متعددة ، يكون انحراف الارتفاع المسموح به هو 1/800 من الدعم المجاور ، ويجب ألا يزيد عن 30 مم ؛

د.كشف انحراف الشبكة حسب المواصفات ومتطلبات التصميم.بعد البناء ، يجب ألا يزيد انحراف إطار الفضاء الفولاذي عن 115٪ من قيمة حساب التصميم.(الحد الأقصى لقيمة الانحراف لإطار الشبكة L / 250)

4. في حالة وجود كرات لحام محليًا ، يتم استخدام لحام الأخدود في لحام كرة اللحام والقضيب ، ويجب ألا تكون درجة خط اللحام أقل من الدرجة الثانية.

5. بعد الانتهاء من تركيب إطار الفضاء الفولاذي ، يجب أن يكون سطح وصلات وقضبان إطار الفضاء نظيفًا وخاليًا من الندوب والأوساخ.يجب ملء الوصلات والثقوب الزائدة في الوصلات الكروية للمسامير وإغلاقها بالشحم.

6. أثناء استخدام الشبكة ، يجب إجراء صيانة شاملة ضد التآكل كل 4 إلى 5 سنوات.

 

1. The installation of the grid frame must be carried out after the acceptance of the lower structure axis and the embedded board. The requirements for the lower support are: the height difference between adjacent supports (distance L2): the smaller value of L2/800 and 10mm, at the same elevation Height difference between the highest and lowest support: 20mm; 2. Determine the installation process of the grid according to the force and structural characteristics of the grid and the actual construction conditions on site; 3. After the grid frame is installed, it should be checked: a. The allowable value of the vertical and horizontal side length deviation is 1/2000 of the length, and should not be greater than 30mm; b. The allowable value of center offset should be 1/3000 of the span of the grid, and should not be greater than 30mm; c. For the mesh frame supported by the periphery, the allowable height deviation is 1/400 of the adjacent support, and should not be greater than 15mm, and the maximum and minimum should not be greater than 30mm; for the mesh frame supported by multiple points, the allowable height deviation is 1/800 of the adjacent support, and should not be greater than 30mm; d. Detect the deflection of the grid according to the specifications and design requirements. After construction, the deflection of the grid frame shall not be greater than 115% of the design calculation value. (Maximum deflection value of grid frame L/250) 4. If there are welding balls locally, groove welding is used for welding the welding ball and the rod, and the welding seam grade should not be lower than the second grade. 5. After the installation of the grid frame is completed, the surface of the joints and rods should be clean and free of scars and dirt. The joints and excess holes of the bolt ball joints should be filled and sealed with grease. 6. During the use of the grid, comprehensive anti-corrosion maintenance should be carried out every 4 to 5 years.
