Merero

Lumela, tloo ho bona lihlahisoa tsa rona!
Steel space grid gas station project construction

Morero ona ke sebaka sa lisekoere tsa lisekoere / bophahamo ba limithara tse 16 / bolelele bohle ba limithara tse 30 / bolelele ba limithara tse 18

1. Ho kenngoa ha foreimi ea sebaka sa tšepe ho tlameha ho etsoa ka mor'a ho amoheloa ha mohaho o ka tlaase oa mohaho le boto e kentsoeng.Litlhoko tsa tšehetso e tlaase ke: phapang ea bophahamo pakeng tsa litšehetso tse haufi (bohōle ba L2): boleng bo fokolang ba L2 / 800 le 10mm, ka bophahamo bo tšoanang Phapang ea bophahamo pakeng tsa tšehetso e phahameng le e tlaase ka ho fetisisa: 20mm;

2. Etsa qeto ea ts'ebetso ea ho kenya sebaka sa tšepe ea sebaka sa tšepe ho ea ka matla le litšobotsi tsa sebopeho sa marang-rang le maemo a sebele a kaho setšeng;

3. Ka mor'a hore foreimi ea sebaka sa tšepe e kenngoe, e lokela ho hlahlojoa:

a.Boleng bo lumelletsoeng ba ho kheloha ha bolelele ba lehlakore le otlolohileng le le rapameng ke 1/2000 ea bolelele, 'me ha ea lokela ho ba kholo ho feta 30mm;

b.Theko e lumelletsoeng ea setsi sa offset e lokela ho ba 1/3000 ea bolelele ba foreimi ea sebaka sa tšepe, 'me ha ea lokela ho ba kholo ho feta 30mm;

c.Bakeng sa foreime ea letlooeng e tšehelitsoeng ke periphery, phapang e lumelletsoeng ea bophahamo ke 1/400 ea tšehetso e haufi, 'me ha ea lokela ho ba kholo ho feta 15mm,' me boholo le bonyane ha boa lokela ho ba kholo ho feta 30mm;bakeng sa foreimi ea letlooeng e tšehetsoeng ke lintlha tse ngata, phapang e lumelletsoeng ea bophahamo ke 1/800 ea tšehetso e haufi, 'me ha ea lokela ho ba kholo ho feta 30mm;

d.Lemoha ho kheloha ha gridi ho latela lintlha le litlhoko tsa moralo.Kamora ho hahoa, ho kheloha ha foreimi ea sebaka sa tšepe ha hoa lokela ho ba kholo ho feta 115% ea boleng ba lipalo tsa moralo.(Boleng bo phahameng ba ho kheloha ba foreimi ea grid L/250)

4. Haeba ho na le libolo tsa welding sebakeng sa heno, welding ea groove e sebelisoa bakeng sa ho kenya bolo ea welding le molamu, 'me boemo ba seam seam ha boa lokela ho ba tlase ho sehlopha sa bobeli.

5. Ka mor'a hore ho behoe foreimi ea sebaka sa tšepe ho phethoa, bokaholimo ba marang-rang a sebaka sa marang-rang le lithupa li lokela ho hloeka 'me ho se na maqeba le litšila.Manonyeletso le masoba a feteletseng a lihlopha tsa bolo ea bolt li lokela ho tlatsoa le ho tiisoa ka mafura.

6. Nakong ea tšebeliso ea marang-rang, tlhokomelo e pharaletseng e khahlanong le kutu e lokela ho etsoa lilemo tse ling le tse ling tse 4 ho isa ho tse 5.

 

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.
