Steel space grid gas station project construction

Tämä projekti on neliön muotoinen tilakehys / korkeus 16 metriä / kokonaispituus 30 metriä / kokonaisjänneväli 18 metriä

1. Teräksisen tilakehyksen asennus tulee suorittaa alemman rakenteen akselin ja upotetun levyn hyväksymisen jälkeen.Alatuen vaatimukset ovat: vierekkäisten tukien välinen korkeusero (etäisyys L2): pienempi arvo L2/800 ja 10mm, samalla korkeudella Korkeusero korkeimman ja alimman tuen välillä: 20mm;

2. Määritä terästilarungon asennusprosessi ristikon voiman ja rakenteellisten ominaisuuksien sekä paikan päällä vallitsevien rakennusolosuhteiden mukaan;

3. Kun terästilakehys on asennettu, se tulee tarkistaa:

a.Pysty- ja vaakasuuntaisen sivun pituuspoikkeaman sallittu arvo on 1/2000 pituudesta, eikä se saa olla suurempi kuin 30 mm;

b.Keskisiirtymän sallitun arvon tulee olla 1/3000 terästilakehyksen jännevälistä, eikä se saa olla suurempi kuin 30 mm;

c.Kehyksen tukeman verkkokehyksen sallittu korkeuspoikkeama on 1/400 viereisestä tuesta, eikä se saa olla suurempi kuin 15 mm, ja enimmäis- ja vähimmäiskorkeus ei saa olla suurempi kuin 30 mm;useiden pisteiden tukeman verkkokehyksen sallittu korkeuspoikkeama on 1/800 viereisestä tuesta, eikä se saa olla suurempi kuin 30 mm;

d.Tunnista ristikon taipuma eritelmien ja suunnitteluvaatimusten mukaisesti.Teräsrungon taipuma ei saa rakentamisen jälkeen olla suurempi kuin 115 % suunnittelulaskennasta.(Rätikkökehyksen suurin taipuma-arvo L/250)

4. Jos hitsauskuulia on paikallisesti, hitsauspallon ja -tangon hitsaukseen käytetään urahitsausta, eikä hitsaussauman laatu saa olla toista laatua alhaisempi.

5. Teräsrungon asennuksen jälkeen tilakehyksen liitosten ja tankojen pinnan tulee olla puhdas ja vapaa arpeista ja liasta.Pulttipalloliitosten liitokset ja ylimääräiset reiät tulee täyttää ja tiivistää rasvalla.

6. Ritikon käytön aikana on suoritettava kattava korroosionestohuolto 4-5 vuoden välein.

 

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.
