VUkuhlolwa, ukuphakanyiswa, kunye nokupakishwa kweemfumba zamaphepha
1. Ukuhlolwa kweemfumba zamaphepha
Kwiimfumba zamaphepha, kukho ukuhlolwa kwezinto eziphathekayo kunye nokuhlolwa okubonakalayo ukulungisa iimfumba zamaphepha ezingahlangabezani neemfuno zokunciphisa ubunzima ngexesha lenkqubo yokufaka.
(1) Ukuhlolwa okubonakalayo: kubandakanywa iziphene zomhlaba, ubude, ububanzi, ubukhulu, umlinganiselo we-rectangular ekupheleni, ukuthe tye, kunye nemilo yokutshixa. Phawula:
a. Amalungu adityanisiweyo achaphazela ukuqhuba kweemfumba zamaphepha kufuneka asuswe;
b. Imingxuma yokusika kunye neziphene zecandelo kufuneka ziqiniswe;
c. Ukuba imfumba yeshiti idliwe kakhulu, linganisela ubukhulu becandelo layo. Ngokomgaqo, zonke iimfumba zamaphepha kufuneka zihlolwe umgangatho wokubonwayo.
(2) Ukuhlolwa kwezinto eziphathekayo: uvavanyo olubanzi lokubunjwa kweekhemikhali kunye neempawu zemishini yezinto ezisisiseko zemfumba yephepha. Oku kubandakanya uhlalutyo lokwakheka kweekhemikhali zentsimbi, i-tensile kunye neemvavanyo zokugoba zamacandelo, iimvavanyo zamandla okutshixa, kunye neemvavanyo zokwandisa. Ubalulo ngalunye lwemfumba yamaphepha kufuneka lwenziwe ubuncinci uvavanyo lwe-tensile kunye nokugoba; Iimvavanyo ezimbini zesampulu kufuneka zenziwe kwiimfumba zamaphepha ezinobunzima obungama-20-50t.
2. Ukuphakanyiswa kweemfumba zentsimbi yentsimbi
Ukulayishwa kunye nokulayishwa kweemfumba zeshiti zetsimbi kufuneka kuqhutywe ngokuphakanyiswa kwamanqaku amabini. Xa uphakamisa, inani leentsimbi zentsimbi eziphakanyisiweyo ngexesha ngalinye akufanele libe likhulu, kwaye kufuneka kuthathwe unonophelo ukukhusela isitshixo ukuphepha umonakalo. Iindlela zokunyusa ziquka ukunyuswa kwenqwaba kunye nokuphakanyiswa okukodwa. Ukunyuswa kweenyanda ngokuqhelekileyo kusebenzisa iintambo zentsimbi zokuhlanganisa, ngelixa ukuphakanyiswa okukodwa kudla ngokusetyenziswa izixhobo ezikhethekileyo zokuphakamisa.
3. Ukupakishwa kweemfumba zentsimbi
Indawo yokupakisha iimfumba zeshiti zetsimbi kufuneka zikhethwe kwindawo ethe tyaba kwaye eqinileyo engayi kucwina okanye ikhubazeke ngenxa yoxinzelelo olunzima, kwaye kufuneka kube lula ukuyihambisa kwindawo yokwakha inqwaba. Xa i-stacking, ingqalelo kufuneka ihlawulwe koku kulandelayo:
(1) Ucwangco, indawo, indlela kunye noyilo lweplani yokupakisha kufuneka kuthathelwe ingqalelo kulwakhiwo lwexesha elizayo;
(2) Iimfumba zamaphepha entsimbi kufuneka zipakishwe ngokwemodeli, iinkcukacha kunye nobude, kwaye iimpawu kufuneka zimiswe kwindawo yokupakisha;
(3)Iimfumba zamaphepha entsimbi kufuneka zipakishwe ngokwamaleko, kunye nenani leemfumba kumaleko ngamnye ngokuqhelekileyo lingadluli kwi-5. Izinto zokulala kufuneka zibekwe phakathi komaleko ngamnye, isithuba phakathi kwabantu abalalayo sibe ziimitha ezi-3 ukuya kwezi-4, kunye namaleko angaphezulu nasezantsi eendawo zokulala. kufuneka ibe kumgca othe nkqo ofanayo. Ubude obupheleleyo be-stacking akufanele budlule iimitha ezi-2.
VI. Ukufakwa kwesikhokelo sesikhokelo.
Ekwakhiweni kweemfumba zentsimbi, ukuze kuqinisekiswe indawo echanekileyo ye-axis yemfumba kunye nokuma kwemfumba, lawula ukuchaneka kokuqhubela phambili, ukuthintela ukuguqulwa kwe-buckling ye-sheet sheet kunye nokuphucula amandla okungena kwemfumba, a isakhelo esisikhokelo esinokuqina okuthile, okwakwaziwa ngokuba yi "construction purlin", sifakwe ngokubanzi. Isakhelo sesikhokelo sithatha ifom enye-icala eliphindwe kabini, ngokuqhelekileyo iqulunqwe ngumqa wesikhokelo kunye neemfumba ze-purlin. Isithuba phakathi kweemfumba zepurlin ngokuqhelekileyo yi-2.5 ~ 3.5m. Isithuba phakathi kwee-purlins ezinamacala amabini akufuneki sibe sikhulu kakhulu, ngokubanzi sibe sikhulu kancinane kunobunzima bodonga lwemfumba yamaphepha nge-8 ~ 15mm. Xa ufaka isakhelo sesikhokelo, la manqaku alandelayo kufuneka aqatshelwe:
1)Sebenzisa i-theodolite kunye nenqanaba ukulawula kunye nokulungelelanisa indawo yebhodi yesikhokelo.
2)Ukuphakama kwebhodi yesikhokelo kufuneka kube yinto efanelekileyo, ekufuneka ihambelane nokulawula ukuphakama kokwakhiwa kwentsimbi yentsimbi kunye nokuphucula ukusebenza kakuhle kokwakhiwa.
3)Umqadi wesikhokelo akufuneki ucwilise okanye ukhubazeke njengoko imfumba yeshiti lentsimbi iqhutywa nzulu.
4)Isikhundla sombhobho wesikhokelo kufuneka sibe ngokuthe nkqo ngokusemandleni kwaye akufanele singqubuzane nentsimbi yentsimbi.
