【導(dǎo)讀】土木工程結(jié)構(gòu)常用到兩種材料，即鋼筋混凝土以及結(jié)構(gòu)鋼，對于土木工程來說，不僅要從結(jié)構(gòu)特性的角度考慮，還要考慮施工的成本有效性以及施工有效性。就分析了鋼結(jié)構(gòu)在土木工程中的特點(diǎn)，并簡單闡述鋼結(jié)構(gòu)的施工要點(diǎn)?？梢岳糜嘘P(guān)的國家標(biāo)準(zhǔn)來確定結(jié)構(gòu)鋼的構(gòu)件性能，這些標(biāo)準(zhǔn)中列出。近幾年來，建筑用鋼發(fā)生了。定出7個(gè)鋼種和8個(gè)強(qiáng)度級別。根據(jù)屈服強(qiáng)度其范圍為260～。鋼種類型和強(qiáng)度級別的選擇就非常重要。從整體來說，采用鋼結(jié)構(gòu)可以減少物料。的剛性有著顯著的優(yōu)勢。建筑物直接依賴于主要結(jié)構(gòu)框架經(jīng)歷大的非彈性變形時(shí)的滯后耗能性。以說是目前使用最廣泛的、韌性最好的工程材料之一。不過材料內(nèi)在的延性并不。構(gòu)系統(tǒng)可以提供最佳的設(shè)計(jì)靈活性以及最大的空間利用率。適合繼續(xù)承載的巨大變形為結(jié)構(gòu)設(shè)計(jì)的極限狀態(tài)為準(zhǔn)則。并且目前鋼結(jié)構(gòu)的生產(chǎn)標(biāo)準(zhǔn)、價(jià)格標(biāo)準(zhǔn)以及質(zhì)量標(biāo)準(zhǔn)都沒有統(tǒng)一，頭做焊接工藝的試驗(yàn)，定出焊接的格料和各項(xiàng)參數(shù)。
【正文】 parameters. Between the beam and the beam, the connection between the beams and columns, you can take the accuracy of the welded connections or highstrength bolts, pay attention to the highstrength bolts connecting holes. System hole, there are two, one is a high precision CNC drilling, another is relatively low precision template system holes. Technical conditions allow more suitable for multiaxis CNC drilling. Transported to the site to test the bolts parameters, installation can not be forced to tighten with a wrench into or forcibly break into with a hammer, step screwed into the screw to go through the beginning, retighten and the final twist. 、 The steel ponents stacked and select installation of mechanical Location Typically the case of the land area of the mounting structure for the structure covers an area of times. Transported to the site from the transit yard supporting steel members in accordance with the order of the installed water handling machinery placed on the installation of machinery within the radius of gyration. Because of transportation reasons caused by the deformation of the ponent, at the construction site should be corrected. General installation of steel structures used tower cranes, the length of the arm to have enough coverage, and lifting capacity accordingly enough to meet the lifting requirements of various parts of the ponent. Wire rope capacity must be able to meet the the lifting height requirements。 lifting speed enough grades to meet the installation requirements. In the case of multimachine operation, the arm height difference should be enough to avoid unsafe collision, to ensure safe operation. Have the appropriate safety distance between the tower crane boom and tower collide. The steel structure is more appropriate in a structured, wellproportioned and relatively flat construction plane, so the installation of the layout of the pipeline to local conditions. 、 Paint process 、 Primary treatment First clean the surface of the metal, and then do the rust. Manual processing first brush repeatedly hit with a wire brush, then polished fine emery cloth, making a bright, smooth surface, and then use a cotton yarn or gauze to clean polished stainless powder and floating dust. If severe surface corrosion with a wire brush and blade handle, large areas of rust, you can use the grinder with the cleanup. 、 Coated with antirust paint and putty To ensure that the metal surface dry before painting, water will have to wipe it dry immediately. Applied to fine brush, brush full of paint in place, and pay attention to the rivet holes can not paint into. Until the time of the antirust paint dry, putty and paint system ponent surface defects gelling. Putty in the right amount of red lead powder or paste paint, thereby increasing its dry hard. Polished smooth the putty is dry and clean. Stacked too long, they have to do it again brushing. 、 Coated with phosphate primer Phosphate primer primer and phosphate solution. Two hours later brushing phosphate primer can be painted in other paint or primer. Typically, in twentyfour hours can phosphate residue with water or brush the surface to be cleaned. Dried formed on the surface of a uniform graybrown phosphate coating, on behalf of the phosphide has been reached. 、 Brush paint Brush paint many reasons brush, oil or else stream does not fall, full uniform, bright color and consistent. Brushing to check the to avoid leakage brush. The steel structure topcoats usually need to brush more than twice the thickness of 70microns.
