Steel space grid gas station project construction

Ang proyektong ito ay isang parisukat na space frame / taas na 16 metro / kabuuang haba 30 metro / kabuuang span 18 metro

1. Ang pag-install ng steel space frame ay dapat isagawa pagkatapos ng pagtanggap ng mas mababang axis ng istraktura at ang naka-embed na board.Ang mga kinakailangan para sa mas mababang suporta ay: ang pagkakaiba sa taas sa pagitan ng mga katabing suporta (distansya L2): ang mas maliit na halaga ng L2/800 at 10mm, sa parehong elevation Pagkakaiba sa taas sa pagitan ng pinakamataas at pinakamababang suporta: 20mm;

2. Tukuyin ang proseso ng pag-install ng steel space frame ayon sa puwersa at mga katangian ng istruktura ng grid at ang aktwal na mga kondisyon ng konstruksiyon sa site;

3. Pagkatapos mai-install ang steel space frame, dapat itong suriin:

a.Ang pinahihintulutang halaga ng vertical at horizontal side length deviation ay 1/2000 ng haba, at hindi dapat mas malaki sa 30mm;

b.Ang pinahihintulutang halaga ng center offset ay dapat na 1/3000 ng span ng steel space frame, at hindi dapat higit sa 30mm;

c.Para sa mesh frame na sinusuportahan ng periphery, ang pinapayagang paglihis ng taas ay 1/400 ng katabing suporta, at hindi dapat mas malaki sa 15mm, at ang maximum at minimum ay hindi dapat mas malaki sa 30mm;para sa mesh frame na sinusuportahan ng maraming puntos, ang pinahihintulutang paglihis sa taas ay 1/800 ng katabing suporta, at hindi dapat hihigit sa 30mm;

d.Alamin ang pagpapalihis ng grid ayon sa mga pagtutukoy at mga kinakailangan sa disenyo.Pagkatapos ng konstruksiyon, ang pagpapalihis ng steel space frame ay hindi dapat lalampas sa 115% ng halaga ng pagkalkula ng disenyo.(Maximum na halaga ng pagpapalihis ng grid frame L/250)

4. Kung mayroong lokal na welding balls, ang groove welding ay ginagamit para sa welding ng welding ball at ang rod, at ang welding seam grade ay hindi dapat mas mababa kaysa sa pangalawang grado.

5. Matapos makumpleto ang pag-install ng steel space frame, ang ibabaw ng space frame joints at rods ay dapat na malinis at walang mga peklat at dumi.Ang mga joints at labis na mga butas ng bolt ball joints ay dapat punan at selyuhan ng grasa.

6. Sa panahon ng paggamit ng grid, ang komprehensibong pagpapanatili ng anti-corrosion ay dapat isagawa tuwing 4 hanggang 5 taon.

 

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.
