Nā papahana

Aloha, hele mai e nīnau i kā mākou huahana!
Steel space grid gas station project construction

ʻO kēia pāhana he pahu ākea huinahā / kiʻekiʻe 16 mika / ka lōʻihi holoʻokoʻa 30 mika / ka lōʻihi holoʻokoʻa 18 mika

1. Pono e ho'okomo 'ia ka pahu kila ma hope o ka 'ae 'ana i ka axis lalo a me ka papa i ho'okomo 'ia.ʻO nā koi no ke kākoʻo haʻahaʻa: ka ʻokoʻa kiʻekiʻe ma waena o nā kākoʻo pili (ka mamao L2): ka waiwai liʻiliʻi o L2/800 a me 10mm, ma ke kiʻekiʻe like ʻO ke kiʻekiʻe ʻokoʻa ma waena o ke kākoʻo kiʻekiʻe a me ka haʻahaʻa: 20mm;

2. E hoʻoholo i ke kaʻina hana hoʻokomo o ka pahu kila e like me ka ikaika a me nā hiʻohiʻona o ka pae a me nā kūlana hana maoli ma ka pūnaewele;

3. Ma hope o ka hoʻokomo ʻia ʻana o ke kahua kila, pono e nānā ʻia:

a.ʻO ke kumukūʻai ʻae ʻia o ka ʻaoʻao ʻaoʻao kū a me ka ʻaoʻao ʻaoʻao ʻaoʻao ʻo 1/2000 o ka lōʻihi, ʻaʻole pono e ʻoi aku ma mua o 30mm;

b.ʻO ka waiwai i ʻae ʻia o ka hoʻokaʻawale waena he 1/3000 o ka lōʻihi o ka pahu kila, ʻaʻole pono e ʻoi aku ma mua o 30mm;

c.No ke kiʻi mesh i kākoʻo ʻia e ka ʻaoʻao, ʻo ka ʻae ʻia ʻana o ke kiʻekiʻe ʻokoʻa he 1/400 o ke kākoʻo e pili ana, a ʻaʻole pono e ʻoi aku ma mua o 15mm, a ʻo ka nui a me ka liʻiliʻi ʻaʻole pono e ʻoi aku ma mua o 30mm;no ke kiʻi mesh i kākoʻo ʻia e nā helu he nui, ʻo ka ʻae ʻia ʻana o ke kiʻekiʻe ʻokoʻa he 1/800 o ke kākoʻo pili, a ʻaʻole pono e ʻoi aku ma mua o 30mm;

d.E ʻike i ka deflection o ka mānoanoa e like me nā kikoʻī a me nā koi hoʻolālā.Ma hope o ke kūkulu ʻia ʻana, ʻaʻole ʻoi aku ka nui o ka deflection o ka pahu kila ma mua o 115% o ka helu helu hoʻolālā.(Waiwai hoʻoneʻe kiʻekiʻe loa o ka pahu pahu L/250)

4. Inā loaʻa nā pōlele kuʻihao ma ka ʻāina, hoʻohana ʻia ke kuʻi kuʻihao no ka wiliwili ʻana i ka pōpō kuʻihao a me ke koʻokoʻo, a ʻaʻole pono e emi ka papa kuʻihao ma mua o ka papa ʻelua.

5. Ma hope o ka pau ʻana o ka hoʻokomo ʻana i ka pahu kila, pono ka maʻemaʻe o ka ʻili o nā hui a me nā koʻokoʻo me ka ʻole o nā ʻōpala a me ka lepo.Pono e hoʻopiha ʻia a hoʻopaʻa ʻia nā ʻāpana a me nā puka keu o nā hui pōpō bolt.

6. I ka wā o ka hoʻohana ʻana i ka māka, pono e mālama ʻia ka mālama anti-corrosion i kēlā me kēia 4 a 5 mau makahiki.

 

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.
