Ihe oru ngo

Ndewo, bịa jụọ ngwaahịa anyị!
Steel space grid gas station project construction

Nke a oru ngo bụ a square oghere etiti / elu 16 mita / ngụkọta ogologo 30 mita / ngụkọta span 18 mita

1. A ghaghị ime ntinye nke oghere oghere ígwè mgbe a nabatara usoro nhazi nke ala na bọọdụ agbakwunyere.Ihe ndị a chọrọ maka nkwado dị ala bụ: ọdịiche dị elu dị n'etiti nkwado dị n'akụkụ (anya L2): uru dị nta nke L2 / 800 na 10mm, n'otu elu dị elu dị iche n'etiti nkwado kachasị elu na nke dị ala: 20mm;

2. Kpebie usoro ntinye nke oghere oghere ígwè dị ka ike na njirimara nhazi nke grid na ọnọdụ ihe owuwu n'ezie na saịtị;

3. Mgbe etinyere oghere oghere ígwè, a ga-enyocha ya:

a.Uru a na-anabata nke ogologo akụkụ kwụ ọtọ na nke kwụ ọtọ bụ 1/2000 nke ogologo, na ekwesịghị ịbụ ihe karịrị 30mm;

b.Uru a na-anabata nke nkwụghachi etiti kwesịrị ịbụ 1/3000 nke ogologo nke oghere oghere igwe, na ekwesịghị ịbụ ihe karịrị 30mm;

c.Maka oghere ntupu na-akwado site na mpụta, ikike ịdị elu a na-ekwe ka ọ bụrụ 1/400 nke nkwado dị n'akụkụ, na ekwesịghị ịbụ ihe karịrị 15mm, na kacha na kacha nta ekwesịghị ịbụ ihe karịrị 30mm;n'ihi na ntupu etiti na-akwado site n'ọtụtụ isi ihe, ikike ịdị elu dị elu bụ 1/800 nke nkwado dị n'akụkụ, na ekwesịghị ịbụ ihe karịrị 30mm;

d.Chọpụta ngbanwe nke grid dị ka nkọwapụta na nhazi chọrọ.Mgbe e wuchara ya, ngbanwe nke oghere oghere ígwè agaghị adị karịa 115% nke uru nhazi nhazi.(Uru ngbanwe kacha nke etiti grid L/250)

4. Ọ bụrụ na e nwere bọọlụ ịgbado ọkụ na mpaghara, a na-eji oghere ịgbado ọkụ na-agbado bọọlụ na mkpanaka, na ọkwa ịgbado ọkụ ekwesịghị ịdị ala karịa ọkwa nke abụọ.

5. Mgbe echichi nke oghere oghere ígwè gwụchara, elu nke oghere oghere oghere na mkpanaka kwesịrị ịdị ọcha na enweghị ntụpọ na unyi.A ga-ejupụta nkwonkwo na oke oghere nke nkwonkwo bọọlụ bolt ma mechie ya na griiz.

6. N'oge ojiji nke okporo, keukwu mgbochi corrosion na-arụ ọrụ ọ bụla 4 ruo 5 afọ.

 

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.
