Steel space grid gas station project construction

این پروژه یک فضای مربع / ارتفاع 16 متر / طول کل 30 متر / کل دهانه 18 متر می باشد.

1. نصب اسپیس فریم فولادی باید پس از پذیرش محور سازه زیرین و تخته تعبیه شده انجام شود.الزامات برای تکیه گاه پایین عبارتند از: اختلاف ارتفاع بین تکیه گاه های مجاور (فاصله L2): مقدار کوچکتر L2/800 و 10 میلی متر، در همان ارتفاع، اختلاف ارتفاع بین بالاترین و پایین ترین تکیه گاه: 20 میلی متر.

2. فرآیند نصب قاب فضای فولادی را با توجه به نیرو و ویژگی های ساختاری شبکه و شرایط واقعی ساخت و ساز در محل تعیین کنید.

3. پس از نصب چارچوب فولادی، باید بررسی شود:

آ.مقدار مجاز انحراف طول ضلع عمودی و افقی 1/2000 طول است و نباید بیشتر از 30 میلی متر باشد.

بمقدار مجاز فاصله مرکزی باید 1/3000 دهانه قاب فضای فولادی باشد و نباید بیشتر از 30 میلی متر باشد.

جبرای قاب توری که توسط حاشیه پشتیبانی می شود، انحراف ارتفاع مجاز 1/400 از تکیه گاه مجاور است و نباید از 15 میلی متر بیشتر باشد و حداکثر و حداقل نباید بیشتر از 30 میلی متر باشد.برای قاب مش که توسط چندین نقطه پشتیبانی می شود، انحراف ارتفاع مجاز 1/800 از تکیه گاه مجاور است و نباید بیشتر از 30 میلی متر باشد.

دانحراف شبکه را با توجه به مشخصات و الزامات طراحی تشخیص دهید.پس از ساخت، انحراف فضای قاب فولادی نباید از 115 درصد مقدار محاسبه طراحی بیشتر باشد.(حداکثر مقدار انحراف قاب شبکه L/250)

4. در صورت وجود گلوله های جوش به صورت موضعی، برای جوش دادن گوی و میله جوش از شیاری استفاده می شود و درجه درز جوش نباید از درجه دو کمتر باشد.

5. پس از اتمام نصب اسپیس فریم فولادی، سطح اتصالات و میله های اسپیس فریم باید تمیز و عاری از اسکار و کثیفی باشد.مفاصل و سوراخ های اضافی اتصالات توپ پیچ باید با گریس پر و مهر و موم شوند.

6. در طول استفاده از شبکه، تعمیر و نگهداری جامع ضد خوردگی باید هر 4 تا 5 سال انجام شود.

 

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.
