Ntchito

Moni, bwerani mudzakambirane zinthu zathu!
Steel space grid gas station project construction

Ntchitoyi ndi lalikulu danga chimango / kutalika 16 mamita / okwana kutalika 30 mamita / okwana span 18 mamita

1. Kuyika kwazitsulo zachitsulo kuyenera kuchitidwa pambuyo pa kuvomereza kwa axis otsika ndi bolodi lophatikizidwa.Zofunikira pa chithandizo chapansi ndi: kusiyana kwa kutalika pakati pa zothandizira zoyandikana (mtunda L2): mtengo wochepa wa L2 / 800 ndi 10mm, pamtunda womwewo Kutalikirana kusiyana pakati pa chithandizo chapamwamba ndi chotsika kwambiri: 20mm;

2. Dziwani njira yopangira chitsulo chachitsulo molingana ndi mphamvu ndi mawonekedwe amtundu wa gridi ndi zochitika zenizeni zomanga pamalopo;

3. Pambuyo poyika chitsulo chachitsulo, chiyenera kufufuzidwa:

a.Mtengo wololeka wa kupatuka koyima ndi kopingasa kutalika kwake ndi 1/2000 utali wake, ndipo sikuyenera kupitirira 30mm;

b.Mtengo wovomerezeka wapakati pazigawo uyenera kukhala 1/3000 wa kutalika kwa chitsulo chachitsulo, ndipo sayenera kukhala wamkulu kuposa 30mm;

c.Kwa chimango cha mauna chothandizidwa ndi periphery, kutalika kovomerezeka kovomerezeka ndi 1/400 ya chithandizo choyandikana, ndipo sikuyenera kukhala kwakukulu kuposa 15mm, ndipo kuchuluka kwake ndi kochepa sikuyenera kupitirira 30mm;pa chimango cha mauna chothandizidwa ndi mfundo zingapo, kupatuka kovomerezeka kwa kutalika ndi 1/800 ya chothandizira moyandikana, ndipo sikuyenera kupitilira 30mm;

d.Dziwani kupatuka kwa gululi molingana ndi zomwe mukufuna komanso kapangidwe kake.Pambuyo pomanga, kupatuka kwa chitsulo chachitsulo sikungakhale kwakukulu kuposa 115% ya mtengo wowerengera.(Kupatuka kwakukulu kwa grid frame L/250)

4. Ngati pali mipira yowotcherera kwanuko, kuwotcherera kwa groove kumagwiritsidwa ntchito powotcherera mpira wowotcherera ndi ndodo, ndipo kalasi yowotcherera msoko siyenera kukhala yotsika kuposa kalasi yachiwiri.

5. Pambuyo poika chitsulo chachitsulo chachitsulo chatsirizidwa, pamwamba pazitsulo za danga ndi ndodo ziyenera kukhala zoyera komanso zopanda zipsera ndi dothi.Zolumikizana ndi mabowo owonjezera amagulu a mpira wa bolt ayenera kudzazidwa ndi kusindikizidwa ndi mafuta.

6. Pogwiritsa ntchito gridi, kukonzanso kwathunthu kwa dzimbiri kuyenera kuchitika zaka 4 mpaka 5 zilizonse.

 

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.
