Miradi

Halo, njoo kushauriana na bidhaa zetu!
Steel space grid gas station project construction

Mradi huu ni sura ya nafasi ya mraba / urefu wa mita 16 / urefu wa jumla mita 30 / jumla ya urefu wa mita 18

1. Ufungaji wa sura ya nafasi ya chuma lazima ufanyike baada ya kukubalika kwa mhimili wa muundo wa chini na bodi iliyoingia.Mahitaji ya usaidizi wa chini ni: tofauti ya urefu kati ya msaada wa karibu (umbali L2): thamani ndogo ya L2/800 na 10mm, kwa mwinuko sawa Tofauti ya urefu kati ya msaada wa juu na wa chini: 20mm;

2. Kuamua mchakato wa ufungaji wa sura ya nafasi ya chuma kulingana na nguvu na sifa za kimuundo za gridi ya taifa na hali halisi ya ujenzi kwenye tovuti;

3. Baada ya sura ya nafasi ya chuma imewekwa, inapaswa kuchunguzwa:

a.Thamani inayokubalika ya kupotoka kwa urefu wa upande wa wima na mlalo ni 1/2000 ya urefu, na haipaswi kuwa kubwa kuliko 30mm;

b.Thamani inayokubalika ya kukabiliana na kituo inapaswa kuwa 1/3000 ya urefu wa fremu ya nafasi ya chuma, na haipaswi kuwa kubwa kuliko 30mm;

c.Kwa fremu ya matundu inayoungwa mkono na pembeni, kupotoka kwa urefu unaoruhusiwa ni 1/400 ya usaidizi wa karibu, na haipaswi kuwa kubwa kuliko 15mm, na kiwango cha juu na cha chini haipaswi kuwa zaidi ya 30mm;kwa fremu ya matundu inayoungwa mkono na pointi nyingi, kupotoka kwa urefu unaoruhusiwa ni 1/800 ya usaidizi wa karibu, na haipaswi kuwa zaidi ya 30mm;

d.Tambua kupotoka kwa gridi ya taifa kulingana na vipimo na mahitaji ya muundo.Baada ya ujenzi, kupotoka kwa sura ya nafasi ya chuma haipaswi kuwa zaidi ya 115% ya thamani ya hesabu ya kubuni.(Thamani ya juu zaidi ya mkengeuko wa fremu ya gridi L/250)

4. Ikiwa kuna mipira ya kulehemu ndani ya nchi, kulehemu kwa groove hutumiwa kwa kulehemu mpira wa kulehemu na fimbo, na daraja la mshono wa kulehemu haipaswi kuwa chini kuliko daraja la pili.

5. Baada ya ufungaji wa sura ya nafasi ya chuma imekamilika, uso wa viungo vya sura ya nafasi na vijiti vinapaswa kuwa safi na bila makovu na uchafu.Viungo na mashimo ya ziada ya viungo vya mpira wa bolt vinapaswa kujazwa na kufungwa na mafuta.

6. Wakati wa matumizi ya gridi ya taifa, matengenezo ya kina ya kupambana na kutu yanapaswa kufanyika kila baada ya miaka 4 hadi 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.
