Steel space grid gas station project construction

Dan il-proġett huwa qafas ta 'spazju kwadru / għoli 16-il metru / tul totali 30 metru / medda totali 18-il metru

1. L-installazzjoni tal-qafas tal-ispazju tal-azzar għandha titwettaq wara l-aċċettazzjoni tal-assi tal-istruttura t'isfel u l-bord inkorporat.Ir-rekwiżiti għall-appoġġ aktar baxx huma: id-differenza fl-għoli bejn l-appoġġi adjaċenti (distanza L2): il-valur iżgħar ta 'L2/800 u 10mm, fl-istess elevazzjoni Differenza tal-għoli bejn l-ogħla u l-aktar appoġġ baxx: 20mm;

2. Iddetermina l-proċess ta 'installazzjoni tal-qafas tal-ispazju tal-azzar skont il-forza u l-karatteristiċi strutturali tal-grilja u l-kundizzjonijiet attwali tal-kostruzzjoni fuq il-post;

3. Wara li jiġi installat il-qafas tal-ispazju tal-azzar, għandu jiġi ċċekkjat:

a.Il-valur permissibbli tad-devjazzjoni tat-tul tal-ġenb vertikali u orizzontali huwa 1/2000 tat-tul, u m'għandux ikun akbar minn 30mm;

b.Il-valur permissibbli tal-offset taċ-ċentru għandu jkun 1/3000 tal-medda tal-qafas tal-ispazju tal-azzar, u m'għandux ikun akbar minn 30mm;

c.Għall-qafas tal-malji appoġġjat mill-periferija, id-devjazzjoni tal-għoli permissibbli hija 1/400 tal-appoġġ li jmissu magħhom, u m'għandhiex tkun akbar minn 15mm, u l-massimu u minimu m'għandux ikun akbar minn 30mm;għall-qafas tal-malji appoġġjat minn punti multipli, id-devjazzjoni tal-għoli permissibbli hija 1/800 tal-appoġġ li jmissu magħhom, u m'għandhiex tkun akbar minn 30mm;

d.Issib id-deflessjoni tal-grilja skont l-ispeċifikazzjonijiet u r-rekwiżiti tad-disinn.Wara l-kostruzzjoni, id-deflessjoni tal-qafas tal-ispazju tal-azzar m'għandhiex tkun akbar minn 115% tal-valur tal-kalkolu tad-disinn.(Valur massimu tad-deflessjoni tal-qafas tal-grilja L/250)

4. Jekk hemm blalen tal-iwweldjar lokalment, l-iwweldjar tal-kanal jintuża għall-iwweldjar tal-ballun tal-iwweldjar u l-virga, u l-grad tal-ħjata tal-welding m'għandux ikun inqas mit-tieni grad.

5. Wara li titlesta l-installazzjoni tal-qafas tal-ispazju tal-azzar, il-wiċċ tal-ġonot u l-vireg tal-qafas tal-ispazju għandu jkun nadif u ħieles minn ċikatriċi u ħmieġ.Il-ġonot u t-toqob żejda tal-bolt ball joints għandhom jimtlew u ssiġillati bil-grass.

6. Waqt l-użu tal-grilja, għandha titwettaq manutenzjoni komprensiva kontra l-korrużjoni kull 4 sa 5 snin.

 

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.
