【摘要】：在我國經(jīng)濟(jì)發(fā)展新常態(tài)下,考慮到重工業(yè)領(lǐng)域?qū)I(yè)廠房的需求朝跨度更大、承載能力更高、建設(shè)速度更快、環(huán)境破壞和污染更小、經(jīng)濟(jì)性更好的方向發(fā)展趨勢,本文以某實(shí)際項(xiàng)目為背景,擬建大跨度單層雙聯(lián)跨重型鋼結(jié)構(gòu)廠房為研究對象,從設(shè)計、加工制作、施工安裝三個階段展開分析,研究大跨度重型鋼結(jié)構(gòu)廠房的造價控制方法。設(shè)計階段,通過對6m、9m、12m三種柱距布置方案的對比分析,研究了鋼架、吊車梁、支撐系統(tǒng)、檁條、墻梁等主要構(gòu)件單位面積用鋼量對柱距變化的敏感性。研究結(jié)果表明,鋼架用鋼量隨柱距增大而減小;吊車梁、支撐系統(tǒng)、檁條、墻梁用鋼量隨柱距增大而增加;柱距為9m時,本文研究廠房的鋼材用量最少。加工制作階段,分析了制作流程、關(guān)鍵制作工序的設(shè)備和工藝對鋼結(jié)構(gòu)廠房制作成本影響。研究結(jié)果表明,切割、焊接、涂裝等關(guān)鍵制作工序中加工設(shè)備和工藝的恰當(dāng)選擇對鋼結(jié)構(gòu)制作成本有顯著影響;采用數(shù)字坡口切割技術(shù)、埋弧自動焊及無氣噴涂法可以有效降低鋼結(jié)構(gòu)的制作成本。施工安裝階段,分析了安裝流程、吊裝方案、安裝工藝、勞動力組織以及設(shè)備機(jī)具等因素對安裝成本的影響。研究結(jié)果表明,按需選取汽車式起重機(jī)并合理安排機(jī)械臺班可有效降低鋼結(jié)構(gòu)的安裝成本;綜合考慮各類因素,制定合理施工組織方案和科學(xué)施工管理方法可實(shí)現(xiàn)對鋼結(jié)構(gòu)安裝成本的有效控制。通過設(shè)計、加工制作、施工安裝三個階段,主要考慮材料、人工、施工機(jī)具三要素,提出了對大跨度重型鋼結(jié)構(gòu)廠房造價控制的合理建議,可為該類型廠房建設(shè)提供有益參考。
[Abstract]:Under the new normal state of China's economic development, considering the trend of the heavy industrial field's demand for industrial factories towards the direction of greater span, higher carrying capacity, faster construction speed, less environmental damage and pollution, and better economy, Taking a practical project as the background, this paper intends to build a large-span single-story double-span heavy steel structure factory building as the research object, and analyzes the cost control method of the large-span heavy steel structure factory building from the three stages of design, manufacture, construction and installation. In the design stage, the sensitivity of steel content per unit area of steel frame, crane beam, support system, purlin and wall beam to the change of column spacing is studied by comparing and analyzing three kinds of column spacing layout schemes of 6 m ~ 9 m ~ (-1) ~ (12 m), such as steel frame, crane beam, support system, purlin, wall beam and so on. The results show that the amount of steel used in steel frame decreases with the increase of column distance, the amount of steel used in crane beam, support system, purlin and wall beam increases with the increase of column distance, and the steel content of the workshop is the least when the distance of column is 9 m. In the manufacturing stage, the influence of the production process, the equipment and the process of the key manufacturing procedure on the production cost of the steel structure factory building is analyzed. The results show that the proper selection of processing equipment and process in key manufacturing processes such as cutting, welding and coating has a significant effect on the cost of steel structure fabrication. Automatic submerged arc welding and airless spraying can effectively reduce the production cost of steel structures. In the stage of construction and installation, the influence of installation process, hoisting scheme, installation technology, labor force organization and equipment on installation cost is analyzed. The research results show that the installation cost of steel structure can be effectively reduced by selecting the automobile crane and arranging the machine shift according to the need, and considering all kinds of factors synthetically, Reasonable construction organization scheme and scientific construction management method can effectively control the installation cost of steel structure. Through the three stages of design, manufacture and installation, mainly considering the three elements of material, labor and construction tools, the reasonable suggestions for the cost control of large-span heavy steel structure factory building are put forward, which can provide a useful reference for the construction of this type of workshop.
