Halo, thig a choimhead air na toraidhean againn!
Steel space grid gas station project construction

Tha am pròiseact seo na fhrèam àite ceàrnagach / àirde 16 meatairean / fad iomlan 30 meatairean / rèis iomlan 18 meatairean

1. Feumar stàladh an fhrèam fànais stàilinn a dhèanamh às deidh gabhail ris an axis structar ìosal agus am bòrd freumhaichte.Is e na riatanasan airson an taic as ìsle: an eadar-dhealachadh àirde eadar taicean faisg air làimh (astar L2): an luach nas lugha de L2 / 800 agus 10mm, aig an aon àrdachadh Eadar-dhealachadh àirde eadar an taic as àirde agus as ìsle: 20mm;

2. Obraich a-mach pròiseas stàlaidh an fhrèam fànais stàilinn a rèir feachd agus feartan structarail a’ ghriod agus na fìor shuidheachaidhean togail air an làrach;

3. An dèidh dhan fhrèam fànais stàilinn a bhith air a stàladh, bu chòir a sgrùdadh:

a.Is e an luach ceadaichte den chlaonadh fad taobh dhìreach is chòmhnard 1/2000 den fhaid, agus cha bu chòir dha a bhith nas àirde na 30mm;

b.Bu chòir gum biodh an luach ceadaichte airson an ionad ionad a bhith 1/3000 de raon frèam an fhànais stàilinn, agus cha bu chòir dha a bhith nas àirde na 30mm;

c.Airson frèam mogal le taic bhon iomall, is e an claonadh àirde ceadaichte 1/400 den taic ri thaobh, agus cha bu chòir dha a bhith nas àirde na 15mm, agus cha bu chòir an ìre as àirde agus as ìsle a bhith nas àirde na 30mm;airson frèam mogal le taic bho ghrunn phuingean, is e an claonadh àirde ceadaichte 1/800 den taic ri thaobh, agus cha bu chòir dha a bhith nas àirde na 30mm;

d.Lorg sèididh a’ ghriod a rèir mion-chomharrachadh agus riatanasan dealbhaidh.Às deidh an togail, cha bhith sèididh an fhrèam fànais stàilinn nas àirde na 115% de luach àireamhachaidh an dealbhaidh.(Luach sèididh as àirde de fhrèam clèithe L/250)

4. Ma tha bàlaichean tàthaidh gu h-ionadail, thathas a 'cleachdadh tàthadh groove airson a bhith a' tàthadh a 'bhàl tàthaidh agus an t-slat, agus cha bu chòir an ìre seam tàthaidh a bhith nas ìsle na an dàrna ìre.

5. Às deidh crìoch a chuir air an fhrèam fànais stàilinn, bu chòir uachdar na joints frèam fànais agus na slatan a bhith glan agus saor bho sgaraidhean is salachar.Bu chòir na h-aonaidhean agus na tuill a bharrachd de na joints ball-bolt a lìonadh agus a sheulachadh le saim.

6. Rè a bhith a 'cleachdadh a' ghriod, bu chòir cumail suas farsaing an-aghaidh corrach a dhèanamh gach 4 gu 5 bliadhna.

 

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.
