Steel space grid gas station project construction

Ko tenei kaupapa he anga mokowā tapawha / teitei 16 mita / te roa katoa 30 mita / te roa katoa 18 mita

1. Ko te whakaurunga o te anga mokowhiti maitai me whakahaere i muri i te whakaaetanga o te tuaka hanganga o raro me te papa whakauru.Ko nga whakaritenga mo te tautoko o raro ko: te rereketanga teitei i waenga i nga tautoko tata (tawhiti L2): te iti ake o te uara o te L2/800 me te 10mm, i te teiteitanga kotahi Te rereketanga teitei i waenga i te tautoko teitei me te iti rawa: 20mm;

2. Whakatauhia te tukanga whakaurunga o te anga mokowhiti maitai i runga i te kaha me nga ahuatanga hanganga o te matiti me nga tikanga hanga i runga i te waahi;

3. I muri i te whakaurunga o te anga mokowhiti maitai, me tirotiro:

a.Ko te uara e whakaaetia ana o te inenga roa o te taha poutū me te taha whakapae he 1/2000 o te roa, kaua e nui ake i te 30mm;

b.Ko te uara e whakaaetia ana mo te whakawhanaunga pokapū kia 1/3000 o te whanganga o te anga mokowā maitai, kaua e nui ake i te 30mm;

c.Mo te anga mata e tautokohia ana e te taha taha, ko te ine teitei e whakaaetia ana ko te 1/400 o te tautoko tata, me kaua e nui ake i te 15mm, me te teitei me te iti rawa kia kaua e nui ake i te 30mm;mo te anga mata e tautokohia ana e nga tohu maha, ko te ine teitei e whakaaetia ana ko te 1/800 o te tautoko tata, a kaua e nui ake i te 30mm;

d.Rapua te paheketanga o te matiti i runga i nga whakaritenga me nga whakaritenga hoahoa.I muri i te hanganga, ko te paheketanga o te anga mokowā maitai e kore e nui ake i te 115% o te uara tatauranga hoahoa.(Te uara paopao teitei o te anga matiti L/250)

4. Mēnā he pōro fehokotaki'anga kei te rohe, ka whakamahia te whao whaowhia mo te weriweri i te poi whao me te rakau, a kaua e iti iho te reanga tui i te reanga tuarua.

5. I muri i te whakaurunga o te anga mokowhiti maitai, me ma te mata o nga hononga anga mokowhiti me nga rakau me te kore he whiu me te paru.Me whakakiia nga hononga me nga kohao taikaha o nga hononga porowhita me te hiri ki te hinu.

6. I te wa e whakamahia ana te matiti, me whakahaere te tiaki i te waikura matawhānui ia 4 ki te 5 tau.

 

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.
