【正文】 鼎盛環(huán)保設備生產(chǎn)車間設計 ─────結(jié)構(gòu)部分第一章 方案選擇 材料的選擇材料選擇根據(jù)《門式剛架輕型房屋結(jié)構(gòu)技術(shù)規(guī)程》CECS102：2022 中的相關規(guī)定選取，由于本廠房是輕型門式剛架結(jié)構(gòu)，本身自重較輕且吊車噸位較小，鋼架承受荷載也較小，所以廠房梁、柱、檁條等結(jié)構(gòu)構(gòu)件可選用 Q235 鋼，又由于廠房對材料的沖擊韌性無特殊要求，所以質(zhì)量等級可以選用 B 級，且廠房對鋼材無特殊要求，為了節(jié)省造價，可采用沸騰鋼，因此，長房梁、柱、檁條、吊車梁、壓型鋼板等結(jié)構(gòu)構(gòu)件均可選用 Q235B 鋼材。 屋頂構(gòu)造本廠房屋面采用壓型鋼板有檁體系，即在鋼架斜梁上放置 C 型冷軋薄壁鋼檁條，再鋪設壓型鋼板屋面。為節(jié)約能源，不使外圍護結(jié)構(gòu)流失的熱量過多，外墻，屋面應采取保溫措施。壓型鋼板采用保溫復合式壓型鋼板，板外側(cè)采用 YX35—175—65 型鋼板，內(nèi)板采用平板式鋼板。邊跨內(nèi)天溝做法示意圖 廠房立面設計廠房立面利用矩形窗，墻體勒腳等水平構(gòu)件及其色彩變化形成立面劃分形狀，使立面簡潔大方，具有開朗，明快的效果。?則窗地比為 1/4故滿足采光要求。為滿足采光要求，在兩山墻上設置高側(cè)窗，窗邊距山墻邊緣 1550mm。本廠房擬采用雙側(cè)采光，因此窗地面積比為 / 應大于 1/4。所以廠房頂部標高=+。2．縱向定位軸線對于抗風柱的設置，考慮到跨度為 21m，柱距為 ，盡量使抗風柱間 第 19 頁距與柱距相近，所以 7m 設置抗風柱。為便于機械化生產(chǎn)，減少造價，所以柱距選擇 。關鍵詞：輕型鋼結(jié)構(gòu)，門式剛架，建筑設計，結(jié)構(gòu)設計，基礎設計 第 12 頁AbstractThe design for the light steel structure plant, the use of light portal frame system, the construction of light steel structure light weight, high strength, largespan, steel structure construction period short, lower investment costs, economic benefits. In China it has a more extensive application prospects. Light steel structure of the roof load lighter, and thus a smaller crosssection bar, thin. In addition to its ordinary lighter weight steel structures, material uniformity, accurate and reliable stress calculation, simple processing, a high degree of industrialization, transport and other features easy installation, the general also has easy material to be used than the provinces, the advantages of lighter weight .The design specification, including architectural design, structural design and foundation of three parts. Architectural design for the construction plane to some of the specific forms of choice, plant profile design, plant design elevation, the structure of plant design, door and window schedules. Part of the structural design, including program selection, the design of the crane beam, purlin design, pillar of windresistant design, corbel design, rigid frame design (handcounting puter parison, bination of internal forces), the node design. Chapters detail the main ponents of calculus calculation.Foundation programs include ground handling, foundation design. Part of the design drawings are as follows: plant floor plan, Node elevation profiles and detailed, Frame Construction ,wallbeam purlin plant layout map, construction of crane beam map, support layout map, foundation plan, limesoil paction pile layout map .Key Words: Light steel structure，Portal frame，Architectural Design，Structural design，foundation design 第 13 頁目 錄建筑部分1．1 廠房平面 設計 ..................................................6 建筑平面形式的選擇 .........................................6 柱網(wǎng)的選擇 .................................................6 定位軸線的劃分 .............................................61．橫向定位軸線 ................................................62．縱向定位軸線 ................................................61．2 廠房剖面設計 ..................................................7 廠房高度的確定 .............................................7 室內(nèi)外高差的確定 ...........................................8 廠房天然采光設計 ...........................................8 廠房屋面排水設計 ...........................................8 廠房立面設計 ...................................................9 廠房的構(gòu)造設計 .................................................9 外墻 .......................................................9 外維護結(jié)構(gòu)的保溫設計 ......................................10 屋頂構(gòu)造 ..................................................11 散 水構(gòu)造 ..................................................11 門窗明細表 ....................................................12結(jié)構(gòu)部分第一章 方案選擇 ...................................................13 材料的選擇 ..................................................13 柱網(wǎng)布置 ....................................................13 屋面布 置 ....................................................13 柱間支撐布置 ................................................14 第 14 頁 屋蓋支撐布置 ................................................14 墻面結(jié)構(gòu)布置 ................................................14第二章 吊車梁設計 .................................................15 荷載的計算 ..................................................15 最大輪壓的計算 ..........................................15 橫向荷載設計值 ..........................................15 內(nèi)力計算 ....................................................15 兩臺吊車荷載作用下的內(nèi)力（3 個輪子時） ...................16 兩臺吊車荷載作用下的內(nèi)力（2 個輪子時） ...................17 一臺吊車荷載作用下的內(nèi)力（2 個輪子時） ...................18 兩臺吊車荷載作用下的內(nèi)力（2 個輪子時） ...................19 截面選擇 ....................................................20 毛截面特性 ...............................................20 強度驗算 ....................................................21 正應力 ..................................................21 剪應力 ..................................................22 腹板的局部壓應力 ........................................22 腹板計算高度邊緣處的折算應力 ............................22 穩(wěn)定性驗算 ..................................................23 梁的整體穩(wěn)定性 ...........................................23 腹板的局部穩(wěn)定性 .........................................24 撓度驗算 ....................................................26 支承加勁肋的驗算 ............................................26 焊縫計算 ....................................................28 上翼緣與腹板連接處的角焊縫設計 ..........................28 下翼緣與腹板連接處的連接角焊縫設計 ......................28 支座加勁肋與腹板的焊縫 ..................................28 疲勞驗算 ....................................................28 第 15 頁第三章 檁條設計 ..................................................
