Steel space grid gas station project construction

Dette projekt er en kvadratisk rumramme / højde 16 meter / total længde 30 meter / total spændvidde 18 meter

1. Installationen af ​​stålrumrammen skal udføres efter accept af den nedre strukturakse og den indstøbte plade.Kravene til den nederste understøtning er: højdeforskellen mellem tilstødende understøtninger (afstand L2): den mindste værdi af L2/800 og 10 mm, ved samme højde Højdeforskel mellem højeste og laveste understøtning: 20 mm;

2. Bestem installationsprocessen af ​​stålrumrammen i henhold til kraften og strukturelle egenskaber af gitteret og de faktiske konstruktionsforhold på stedet;

3. Efter at stålrumsrammen er installeret, skal den kontrolleres:

en.Den tilladte værdi af den lodrette og vandrette sidelængdeafvigelse er 1/2000 af længden og bør ikke være større end 30 mm;

b.Den tilladte værdi af midterforskydning bør være 1/3000 af spændvidden af ​​stålrummets ramme og bør ikke være større end 30 mm;

c.For netrammen, der understøttes af periferien, er den tilladte højdeafvigelse 1/400 af den tilstødende støtte og bør ikke være større end 15 mm, og maksimum og minimum bør ikke være større end 30 mm;for netrammen, der understøttes af flere punkter, er den tilladte højdeafvigelse 1/800 af den tilstødende støtte og bør ikke være større end 30 mm;

d.Detekter afbøjningen af ​​gitteret i henhold til specifikationerne og designkravene.Efter konstruktionen må udbøjningen af ​​stålrumrammen ikke være større end 115 % af den konstruktive beregningsværdi.(Maksimal afbøjningsværdi for gitterramme L/250)

4. Hvis der er svejsekugler lokalt, anvendes rillesvejsning til svejsning af svejsekuglen og stangen, og svejsesømsgraden bør ikke være lavere end anden klasse.

5. Efter installationen af ​​stålrumrammen er afsluttet, skal overfladen af ​​rumrammens samlinger og stænger være ren og fri for ar og snavs.Boltenes samlinger og overskydende huller skal fyldes og forsegles med fedt.

6. Under brugen af ​​nettet bør der udføres omfattende anti-korrosionsvedligeholdelse hvert 4. til 5. år.

 

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.
