宜挑选周边巨型src柱，C型钢此类高层为前者。对抗震晦气 使C型钢以最直接的线路传递到根底C型钢高层钢结构规划中，常选用钢混凝土组合结构，C型钢在地震烈度高或很不规矩的高层中，不该单纯为了经济去挑选晦气抗震的中心筒加外框的形式。C型钢机器在钢结构中钢材的堵截应尽可能在剪切机上或锯床上进行，特别是关于薄壁型钢屋架，因下料要求精确，最好选用电动锯割法，不只工效高，并且断面润滑平坦，质量好，长度差错可控制在±1mm以内。
It is advisable to select the surrounding giant SRC columns, such as C steel. The steel and concrete composite structure is often used in the programming of C type steel to be transmitted to the bottom C steel structure with the most direct transmission line, and the C type steel should not be simply selected for the economy to select the central tube and the outer frame for the economy. The steel cutting of C type steel machine should be done on the shear machine or saw machine in the steel structure as far as possible. Especially about the thin-walled steel roof frame, the electric sawing bbbbbb is best chosen because of the precision of the material. It is not only high working efficiency, and the section lubrication is flat, the quality is good, and the length error can be controlled within + 1mm.
厂房建造C型钢也可选用气割为了提高气割质量，宜选用小口径喷嘴，并在切开后用锤子悄悄敲打，使切断平坦，以铲除熔渣，保证焊接质量。一般的说要刚度平均。力学模型清楚。尽可能约束大荷载或移动荷载的影响规模。
In order to improve the quality of gas cutting, the building of C steel can also be used to improve the quality of gas cutting. The small diameter nozzle should be selected and the hammer is used quietly after cutting, so that the cutting is flat and the slag can be removed to ensure the quality of the welding. It is generally said to have an average stiffness. The mechanical model is bbbbb. Limit the scale of large load or moving load as far as possible.
工程厚涂型钢结构防火漆是指涂层厚度在8～50mm的涂料,这类防火涂料的耐火极限可达0.5～3h。在火灾中涂层不胀大,依靠资料的不燃性、低导热性或涂层中资料的吸热性,推迟钢材的升温,保护钢件。
The engineering thick coated steel structure fireproof paint refers to the coating whose thickness is between 8 and 50mm, and the fire resistance of the fireproof coating can reach 0.5 to 3H. The coating does not swell in the fire, and the temperature of the steel is delayed and the steel is protected by the nonflammability of the data, low thermal conductivity or heat absorption of the data in the coating.
结构工程这类钢结构防火涂料选用适宜的粘结剂,再配以无机轻质资料、增强资料。与其他类型的钢结构防火涂料相比,除了具有水溶性防火涂料的一些优点之外,由于它从基料到大多数添加剂都是无机物,因此本钱低价。该类钢结构防火涂料施工一般选用喷涂,多应用在耐火极限要求2h以上的室内钢结构上。但这类产品由于涂层厚,外观装饰性相对较差。

This kind of steel structure fire retardant coating for structural engineering is selected as suitable binder, with inorganic light weight data and enhanced data. Compared with other types of steel structure fireproof coatings, in addition to some of the advantages of water-soluble fireproof coatings, the cost is low because it is from the base material to most of the additives are inorganic. This kind of steel structure fire retardant coating is usually sprayed and applied to indoor steel structures with fire resistance requirements of 2H or more. However, due to the thick coating, the appearance and decoration of these products are relatively poor.
