Molo, yiza kudibana neemveliso zethu!
Steel space grid gas station project construction

Le projekthi yindawo yesakhelo esisikweri / ubude beemitha ezili-16 / ubude bubonke buziimitha ezingama-30 / ubude bubonke buziimitha ezili-18

1. Ukufakwa kwesakhelo sendawo yensimbi kufuneka kuqhutywe emva kokumkelwa kwe-axis yesakhiwo esisezantsi kunye nebhodi edibeneyo.Iimfuno zenkxaso ephantsi zi: umehluko wokuphakama phakathi kweenkxaso ezikufutshane (umgama we-L2): ixabiso elincinci le-L2 / 800 kunye ne-10mm, ekuphakameni okufanayo Ukuphakama kokuphakama phakathi kwenkxaso ephezulu kunye neyona nto iphantsi: 20mm;

2. Ukugqiba inkqubo yofakelo lwesakhelo sendawo yensimbi ngokwendlela yamandla kunye nesakhiwo segridi kunye neemeko zangempela zokwakha kwisiza;

3. Emva kokufakwa kwesakhelo sesithuba sentsimbi, kufuneka sijongwe:

a.Ixabiso elivumelekileyo lokutenxa ubude becala elithe nkqo nelithe tye yi-1/2000 yobude, kwaye akufunekanga ibe nkulu kuno-30mm;

b.Ixabiso elivumelekileyo le-centre offset kufuneka libe yi-1/3000 ye-span ye-steel space frame, kwaye akufanele ibe ngaphezu kwe-30mm;

c.Kwisakhelo se-mesh esixhaswa ngumda, ukutenxa kobude obuvumelekileyo yi-1/400 yenkxaso ekufutshane, kwaye akufanele ibe ngaphezu kwe-15mm, kwaye ubuninzi kunye nobuncinci akufunekanga bube ngaphezu kwe-30mm;kwisakhelo semesh esixhaswa ngamanqaku amaninzi, ukutenxa kobude obuvumelekileyo yi-1/800 yenkxaso ekufutshane, kwaye akufunekanga ibe nkulu kuno-30mm;

d.Khangela ukuphambuka kwegridi ngokweenkcukacha kunye neemfuno zoyilo.Emva kokwakhiwa, ukuphambuka kwesakhelo sendawo yentsimbi akuyi kuba ngaphezu kwe-115% yexabiso lokubala loyilo.(Elona xabiso ligqwesileyo lesakhelo segridi L/250)

4. Ukuba kukho iibhola ze-welding zendawo, i-groove welding isetyenziselwa i-welding ibhola ye-welding kunye nentonga, kwaye ibakala le-welding seam akufanele libe ngaphantsi kwebanga lesibini.

5. Emva kokufakwa kwesakhelo sesithuba sentsimbi kugqityiwe, indawo yokudibanisa i-space frame kunye neentonga kufuneka zihlambuluke kwaye zingabi nazibazi kunye nokungcola.Amalungu kunye nemingxuma engaphezulu kweebhola zebhola kufuneka zizaliswe kwaye zitywinwe ngegrisi.

6. Ngethuba lokusetyenziswa kwegridi, ukugcinwa okupheleleyo kwe-anti-corrosion kufuneka kwenziwe rhoqo kwiminyaka emi-4 ukuya 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.
