Taslamalar

Salam, önümlerimiz bilen maslahatlaşmaga geliň!
Steel space grid gas station project construction

Bu taslama inedördül giňişlik çarçuwasy / beýikligi 16 metr / umumy uzynlygy 30 metr / umumy aralygy 18 metr

1. Polat giňişlik çarçuwasyny gurnamak aşaky gurluş oky we oturdylan tagta kabul edilenden soň amala aşyrylmalydyr.Aşaky goldaw üçin talaplar: goňşy diregleriň arasyndaky beýiklik tapawudy (L2 aralyk): L2 / 800 we 10mm kiçi bahasy, şol bir beýiklikde iň ýokary we iň pes goldawyň arasyndaky beýiklik tapawudy: 20mm;

2. Toruň güýjüne we gurluş aýratynlyklaryna we ýerdäki gurluşyk şertlerine görä polat kosmos çarçuwasynyň gurnama işini kesgitläň;

3. Polat kosmos çarçuwasy gurlansoň, ony barlamaly:

a.Dik we keseligine gapdal uzynlygyň gyşarmagynyň rugsat berilýän bahasy uzynlygyň 1/2000 bolup, 30 mm-den uly bolmaly däldir;

b.Merkezi ofsetiň rugsat berilýän bahasy polat giňişligiň çarçuwasynyň 1/3000 bolmaly we 30 mm-den uly bolmaly däldir;

c.Daş-töweregi goldaýan tor çarçuwasy üçin rugsat berilýän beýiklik gyşarmasy goňşy goldawyň 1/400 bölegi bolup, 15 mm-den köp bolmaly däldir, iň ýokary we iň pes 30 mm-den köp bolmaly däldir;Birnäçe nokat bilen goldanýan tor çarçuwasy üçin, rugsat berilýän beýiklik gyşarmasy goňşy goldawyň 1/800 bolup, 30 mm-den uly bolmaly däldir;

d.Aýratynlyklara we dizaýn talaplaryna laýyklykda gözenegiň ýalňyşlygyny kesgitläň.Gurluşykdan soň polat kosmos çarçuwasynyň deflýasiýasy dizaýn hasaplaýyş bahasynyň 115% -inden köp bolmaly däldir.(L / 250 gözenegiň çarçuwasynyň iň ýokary deflýasiýa bahasy)

4. locallyerli kebşirleýiş toplary bar bolsa, kebşirleýiş topuny we hasany kebşirlemek üçin çukur kebşirlemek ulanylýar we kebşirleýiş tikiş derejesi ikinji synpdan pes bolmaly däldir.

5. Polat kosmos çarçuwasy gurlandan soň, kosmos çarçuwasynyň bogunlarynyň we çybyklarynyň ýüzi arassa we yzlardan we kirlerden arassa bolmalydyr.Bolt top bogunlarynyň bogunlary we artykmaç deşikleri doldurylmaly we ýag bilen möhürlenmeli.

6. Tor ulanylanda, her 4-5 ýyldan bir gezek poslama garşy abatlaýyş işleri geçirilmelidir.

 

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.
