3.栓接:高层钢结构承重构件的高强度螺栓连接应采用摩擦型。高强度螺栓连接施工方便,但连接尺寸过大,因而造价较高,且在大震下容易产生滑移。
3. Bolting: High strength bolt connections for load-bearing components of high-rise steel structures should be friction type. High strength bolt connection is convenient for construction, but the connection size is too large, resulting in high cost and easy to slip under large earthquakes.
铆接形式,在建筑工程中,现已很少采用.
Riveting is now rarely used in construction projects
普通螺栓抗剪性能差, 可在次要结构部位使用.
Ordinary bolts have poor shear resistance and can be used in secondary structural parts
高强螺栓,使用日益广泛.常用8.8s和10.9纤维 驱鸟设备 保定通风管道 塑料土工格栅 检查井模具 流水槽模具 锻造厂家 华尔街铜牛s两个强度等级.根据受力特点分承压型和摩擦型.两者计算方法不同. 高强螺栓很小规格M12. 常用M16~M30. 超大规格的螺栓性能不稳定,应慎重使用。
High strength bolts are increasingly widely used. Two strength grades, 8.8s and 10.9s, are commonly used. According to the stress characteristics, they are divided into compression type and friction type. The calculation methods for the two are different. High strength bolts have a very small size, M12 Commonly used M16~M30. The performance of oversized bolts is unstable and should be used with caution.
自攻螺丝用于板材与薄壁型钢间的次要连接. 在低层墙板式住宅中也常用于主结构的连接. 难以解决的是自攻过程中防腐层的破坏问题。
Self tapping screws are used for secondary connections between plates and thin-walled steel sections In low rise wall panel residential buildings, it is also commonly used for connecting the main structure What is difficult to solve is the problem of damage to the anti-corrosion layer during the self tapping process.
4.焊接: 钢结构焊接连接是传力很充分,有足够的延性;对焊接焊缝的尺寸及形式等,规范有强制规定,应严格遵守. 焊条的选用应和被连接金属材质适应.E43对应Q235,E50对应Q345. Q235与Q345连接时,应该选择低强度的E43,而不是E50.
4. Welding: The welding connection of the steel structure has sufficient force transmission and sufficient ductility; There are mandatory regulations in the specifications for the size and form of welding seams, which should be strictly followed The selection of welding rods should be adapted to the material of the connected metal. E43 corresponds to Q235, and E50 corresponds to Q345 When connecting Q235 to Q345, low strength E43 should be chosen instead of E50
焊接设计中不得任意加大焊缝. 焊缝应尽量与被连接构件接近.其他详细内容可查规范关于焊缝构造方面的规定.
In welding design, it is not allowed to arbitrarily increase the weld seam The weld seam should be as close as possible to the connected component. For other details, please refer to the regulations on weld seam construction in the specifications
5.梁腹板: 应验算栓孔处腹板的净截面抗剪.承压型高强螺栓连接还需验算孔壁局部承压.
5. Beam web: The net cross-sectional shear resistance of the web at the bolt hole should be verified. For high-strength bolt connections under pressure, local pressure on the hole wall should also be verified
