Amaphrojekthi

Sawubona, woza uzobonisana nemikhiqizo yethu!
Steel space grid gas station project construction

Le phrojekthi iyisikwele sohlaka lwesikhala / ukuphakama 16 amamitha / ubude obuphelele 30 amamitha / ingqikithi ye-span 18 amamitha

1. Ukufakwa kohlaka lwesikhala sensimbi kufanele kwenziwe ngemuva kokwamukelwa kwe-axis yesakhiwo esiphansi kanye nebhodi elishunyekiwe.Izidingo zokusekelwa okuphansi yilezi: umehluko wokuphakama phakathi kwezisekelo eziseduze (ibanga L2): inani elincane le-L2/800 kanye ne-10mm, ekuphakameni okufanayo Umehluko wokuphakama phakathi kokusekela okuphezulu nokuphansi kakhulu: 20mm;

2. Ukunquma inqubo yokufaka uhlaka lwesikhala sensimbi ngokusho kwamandla kanye nezici zesakhiwo segridi kanye nezimo zangempela zokwakha esizeni;

3. Ngemuva kokufakwa kwefreyimu yesikhala sensimbi, kufanele ihlolwe:

a.Inani elivumelekile lokuchezuka kobude bohlangothi oluqondile noluvundlile lingu-1/2000 wobude, futhi akufanele libe likhulu kuno-30mm;

b.Inani elivumelekile le-centre offset kufanele libe ngu-1/3000 we-span yohlaka lwesikhala sensimbi, futhi akufanele libe likhulu kuno-30mm;

c.Kufreyimu yemeshi esekelwa indawo ezungezile, ukuchezuka kobude obuvunyelwe kungu-1/400 wosekelo oluseduze, futhi akufanele kube mkhulu kuno-15mm, futhi umkhawulo nobuncane akumele kube kukhulu kuno-30mm;kufreyimu yemeshi esekelwa amaphuzu amaningi, ukuchezuka kobude obuvunyelwe kungu-1/800 wosekelo oluseduze, futhi akufanele kube ngaphezu kuka-30mm;

d.Thola ukuchezuka kwegridi ngokuya ngemininingwane nezidingo zokuklama.Ngemva kokwakhiwa, ukuchezuka kohlaka lwesikhala sensimbi akufanele kube ngaphezu kuka-115% yenani lokubala lokuklama.(Inani eliphezulu lokuchezuka lozimele wegridi L/250)

4. Uma kukhona amabhola e-welding endaweni, i-groove welding isetshenziselwa ukuthungatha ibhola le-welding kanye nenduku, futhi ibanga le-welding seam akufanele libe ngaphansi kwebanga lesibili.

5. Ngemuva kokufakwa kwefreyimu yesikhala sensimbi sekuqediwe, ingaphezulu lezinhlaka zefreyimu yesikhala kanye nezinduku kufanele zihlanzeke futhi zingabi nezibazi nokungcola.Amalunga kanye nezimbobo ezidlulele zebhola le-bolt kufanele zigcwaliswe futhi zivalwe ngamafutha.

6. Ngesikhathi sokusetshenziswa kwegridi, ukugcinwa okuphelele kokulwa nokugqwala kufanele kwenziwe njalo eminyakeni emi-4 kuya kwemi-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.
