常見(jiàn)鋼結(jié)構(gòu)廠(chǎng)房的設(shè)計(jì)問(wèn)題
Common Design Problems of Steel Structure Workshop
很多廠(chǎng)房在搭建時(shí),都會(huì)選用鋼結(jié)構(gòu)材質(zhì),因?yàn)殇摻Y(jié)構(gòu)強(qiáng)度大,建筑成本比較低,施工周期短,對(duì)于鋼結(jié)構(gòu)廠(chǎng)房在設(shè)計(jì)時(shí),有哪些常見(jiàn)問(wèn)題呢?
Many factory buildings are built with steel structure materials, because the steel structure is strong, the construction cost is relatively low, and the construction period is short. What are the common problems in the design of steel structure factory buildings?
1、基礎(chǔ)問(wèn)題:主要表現(xiàn)為地基強(qiáng)度,地基變形以及地基破壞三個(gè)方面。強(qiáng)度問(wèn)題集中在因承載力不足引起的基礎(chǔ)穩(wěn)定性不足的問(wèn)題,變形問(wèn)題多發(fā)生在荷載地基易出現(xiàn)不均勻的沉降、過(guò)大變形的軟土、膨脹土、濕陷性黃土以及季節(jié)凍土等地區(qū),破壞問(wèn)題主要呈現(xiàn)為局部或整體的剪切破壞及沖切剪切破壞等形式。
1. Foundation problems: Foundation strength, foundation deformation and foundation failure are the main manifestations. Strength problems mainly focus on the insufficient stability of foundation caused by insufficient bearing capacity. Deformation problems often occur in the areas of uneven settlement of loaded foundation, soft soil with excessive deformation, expansive soil, collapsible loess and seasonally frozen soil. The failure problems mainly take the form of local or integral shear failure and punching shear failure.
2、鋼屋蓋系統(tǒng)的設(shè)計(jì)問(wèn)題
2. Design of Steel Roof System
鋼結(jié)構(gòu)廠(chǎng)房鋼屋蓋大部分的承重構(gòu)件由細(xì)長(zhǎng)、壁薄的桿件組成,截面的形狀較為復(fù)雜,節(jié)點(diǎn)的應(yīng)力相對(duì)集中且存在偏心,在進(jìn)行屋蓋系統(tǒng)的設(shè)計(jì)時(shí),計(jì)算荷載與計(jì)算簡(jiǎn)圖接近于計(jì)算的極限狀態(tài),系統(tǒng)構(gòu)件承載力的儲(chǔ)備有限,相應(yīng)的系統(tǒng)對(duì)于溫度、超載及腐蝕的作用十分敏銳,偶然的因素就可能導(dǎo)致其失效。
Most bearing components of steel roof of steel structure factory building are composed of slender and thin-walled members. The shape of section is complex, the stress of joints is relatively concentrated and eccentricity exists. When designing roof system, the calculation load and calculation sketch are close to the limit state of calculation. The reserve of bearing capacity of system members is limited, and the corresponding system plays a role in temperature, overload and corrosion. Very sensitive, accidental factors may lead to its failure.
3、檁條、墻梁與拉條問(wèn)題
3. Purlins, Wall Beams and Strings
鋼結(jié)構(gòu)廠(chǎng)房工程的檁條、拉條與墻梁多選用Z形、C形的實(shí)腹式冷彎薄壁型鋼材,這種類(lèi)型的鋼材具有整體剛度較好的優(yōu)點(diǎn),截面的回轉(zhuǎn)半徑與慣性矩較大,可以充分發(fā)揮材料性能。
In purlin, tension bar and wall beam of steel structure factory building, Z-shaped and C-shaped solid-web cold-formed thin-walled steel is mostly used. This kind of steel has the advantages of good overall stiffness, larger turning radius and inertia moment of section, and can give full play to material performance.
鋼結(jié)構(gòu)車(chē)間的防火保護(hù)措施
Fire protection measures for steel structure workshop
1、澆筑混凝土砌筑磚塊法,可在鋼結(jié)構(gòu)車(chē)間上現(xiàn)澆成型或者采用噴射工藝也行,比較適用于沒(méi)有保護(hù)面板的鋼柱防火保護(hù),或者容易碰撞的鋼柱。
1. The method of pouring concrete bricks can be cast in situ or sprayed in steel structure workshop. It is more suitable for steel columns without protective panels for fire protection or easy to collide with.
2、防火涂料方法,具有一定的裝飾效果,方法可刷可噴,高溫時(shí)涂層膨脹增厚可以保護(hù)鋼構(gòu)件,有施工簡(jiǎn)單輕便的特點(diǎn),比較適合用于隱蔽的構(gòu)件等。
2. Fire-proof coating method has certain decorative effect. It can be brushed and sprayed. Expansion and thickening of coating can protect steel components at high temperature. It has the characteristics of simple and light construction, and is more suitable for concealed components.
 
                                                  濟(jì)南輕型鋼結(jié)構(gòu)     
 
3、輕質(zhì)防火厚板包覆法:這種方法不僅損耗小、耐老化、施工方便周期短等特點(diǎn)。
3. Lightweight fire-proof thick plate coating method: This method not only has the characteristics of low loss, aging resistance, short construction period and so on.
4、復(fù)合保護(hù)方法:在表面要求裝飾,需要粘貼柔性毯狀隔熱材料,或者涂敷厚質(zhì)防火涂料的鋼柱,采用柔性毯狀隔熱材料,或者緊貼鋼板用的防火涂料,表面可使用防火薄板做罩面板。
4. Compound protection method: Decoration is required on the surface. Flexible blanket insulation material or steel column coated with thick fire retardant coating are required. Flexible blanket insulation material or fire retardant coating for steel plate are used. Fire retardant sheet can be used as cover panel on the surface.
