Steel space grid gas station project construction

O lenei poloketi ose fa'avaa sikuea sikuea / maualuga 16 mita / umi atoa 30 mita / aofa'i atoa 18 mita

1. O le faʻapipiʻiina o le uʻamea avanoa avanoa e tatau ona faʻatinoina pe a maeʻa le taliaina o le pito i lalo o le fausaga ma le laupapa faʻapipiʻi.O mea e manaʻomia mo le lagolago pito i lalo o: le maualuga o le eseesega i le va o lagolago lata ane (mamao L2): o le tau laʻititi o le L2 / 800 ma le 10mm, i le maualuga tutusa O le maualuga o le eseesega i le va o le lagolago maualuga ma le maualalo: 20mm;

2. Fuafua le faʻatulagaina o le faʻapipiʻiina o le vaʻa avanoa uʻamea e tusa ai ma le malosi ma uiga faʻatulagaina o le faʻasologa ma tulaga tonu o le fausiaina i luga o le nofoaga;

3. A maeʻa ona faʻapipiʻi le faʻavaa avanoa uamea, e tatau ona siaki:

a.Ole tau fa'ataga ole va'aiga fa'alava ma fa'alava itu umi ole 1/2000 ole umi, ma e le tatau ona sili atu ile 30mm;

e.O le tau fa'ataga o le fa'aoga ogatotonu e tatau ona 1/3000 o le lautele o le fa'avaa avanoa, ma e le tatau ona sili atu nai lo le 30mm;

i.Mo le faʻavaa faʻavaa o loʻo lagolagoina e le pito, o le faʻatagaina o le maualuga o le eseesega o le 1/400 o le lagolago lata ane, ma e le tatau ona sili atu nai lo le 15mm, ma le maualuga ma le laʻititi e le tatau ona sili atu nai lo le 30mm;mo le faʻavaa faʻavaa o loʻo lagolagoina e le tele o mea, o le faʻatagaina o le maualuga o le eseesega o le 1/800 o le lagolago lata ane, ma e le tatau ona sili atu nai lo le 30mm;

o.Su'esu'e le fa'afefe o le fa'asologa e tusa ai ma fa'amatalaga ma mana'oga.A maeʻa le fausiaina, e le tatau ona sili atu i le 115% o le faʻatusatusaga o le faʻatulagaina o mamanu.(Tausaga aupito maualuga o le fe'avea'i o le fa'avaa laina L/250)

4. Afai o loʻo i ai ni polo uelo i le lotoifale, e faʻaaogaina le faʻafefeteina mo le ueloina o le polo uʻamea ma le tootoo, ma e le tatau ona laʻititi le togi o le suʻisuʻi nai lo le vasega lua.

5. A maeʻa le faʻapipiʻiina o le vaʻa avanoa uamea, e tatau ona mama le pito i luga ole vaʻa vaʻavaʻa ma faʻamau ma leai ni maʻila ma palapala.O sooga ma pu sili atu o sooga polo polo e tatau ona faʻatumu ma faʻamaufaʻailogaina i le gaʻo.

6. I le taimi o le faʻaogaina o le faʻasologa, e tatau ona faʻatinoina le tausiga atoatoa o le anti-corrosion i le 4 i le 5 tausaga.

 

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.
