Steel space grid gas station project construction

Šis projektas yra kvadratinis erdvės rėmas / aukštis 16 metrų / bendras ilgis 30 metrų / bendras tarpas 18 metrų

1. Plieninio erdvės karkaso montavimas turi būti atliktas priėmus apatinę konstrukcijos ašį ir įmontuotą plokštę.Reikalavimai apatinei atramai yra: aukščių skirtumas tarp gretimų atramų (atstumas L2): mažesnė L2/800 reikšmė ir 10mm, tame pačiame aukštyje Aukščių skirtumas tarp aukščiausios ir žemiausio atramos: 20mm;

2. Nustatykite plieninio erdvės karkaso montavimo procesą pagal tinklo jėgą ir konstrukcines charakteristikas bei faktines statybos sąlygas vietoje;

3. Sumontavus plieninį erdvės rėmą, reikia patikrinti:

a.Leidžiama vertikalios ir horizontalios kraštinių ilgio nuokrypio vertė yra 1/2000 ilgio ir neturi būti didesnė nei 30 mm;

b.Leidžiama centro poslinkio vertė turi būti 1/3000 plieninio tarpinio rėmo tarpatramio ir neturi būti didesnė nei 30 mm;

c.Tinklinio rėmo, atremto į periferiją, leistinas aukščio nuokrypis yra 1/400 gretimos atramos ir neturi būti didesnis nei 15 mm, o didžiausias ir mažiausias – ne didesnis kaip 30 mm;tinklinio rėmo, paremto keliais taškais, leistinas aukščio nuokrypis yra 1/800 gretimos atramos ir neturi būti didesnis nei 30 mm;

d.Nustatykite tinklelio įlinkį pagal specifikacijas ir projektavimo reikalavimus.Pastačius plieninio erdvės karkaso įlinkis turi būti ne didesnis kaip 115 % projektinės skaičiavimo vertės.(Maksimali tinklelio rėmo įlinkio vertė L/250)

4. Jei vietoje yra suvirinimo rutulių, suvirinimo rutuliui ir strypui suvirinti naudojamas suvirinimas grioveliais, o suvirinimo siūlės klasė neturi būti žemesnė nei antroji.

5. Užbaigus plieninio tarpinio rėmo montavimą, tarpinio rėmo jungčių ir strypų paviršius turi būti švarus, be randų ir nešvarumų.Varžtų rutulinių jungčių jungtys ir perteklinės skylės turi būti užpildytos ir užsandarintos tepalu.

6. Tinklelio naudojimo metu kas 4–5 metus reikia atlikti visapusišką antikorozinę priežiūrą.

 

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.
