The invention is used in the field of bridge construction.

摘要：【中文】本发明公开了一种斜拉桥混凝土梁组合式挂篮施工方法，斜拉索施工分两次张拉，分别在节段浇筑后及挂篮走行后进行，减少因不同工况对新旧混凝土间的内力影响，减少交叉作业，加强对成桥线形的有效控制；由于主梁两箱室中间为小横梁，混凝土浇筑完成后挂篮前移时，由于横梁的阻隔，需将挂篮底模系统先进行下放操作。因此横梁部位板应采用便于安拆的小块木模，使拆除后的模板及支架平铺于挂篮底模上，以减小挂篮吊挂系统下放高度，节省下放时间，且能保证桥下通航净空要求。此发明用于桥梁挂篮施工领域。 【EN】The invention discloses a combined hanging basket construction method for concrete beams of a cable-stayed bridge, wherein the construction of a stay cable is divided into two times of tensioning, and the two times of tensioning are respectively carried out after segment pouring and after the hanging basket runs, so that the influence of internal force between new and old concrete due to different working conditions is reduced, the cross operation is reduced, and the effective control on the line shape of a formed bridge is enhanced; because the small cross beam is arranged between the two box chambers of the main beam, when the hanging basket moves forwards after concrete pouring is finished, the hanging basket bottom die system needs to be placed down firstly due to the obstruction of the cross beam. Therefore, the beam position plate is made of small wood molds convenient to mount and dismount, and the dismounted templates and supports are flatly laid on the hanging basket bottom die to reduce the lowering height of the hanging basket hanging system, save the lowering time and guarantee the requirement of navigation clearance under the bridge. The invention is used for the field of bridge hanging basket construction.

摘要：【中文】本发明公开了一种菱形索塔下塔柱线形调整结构及调整方法，包括下塔柱、横撑杆和若干钢绞线等，下塔柱包括左墩身和右墩身，横撑杆设于左墩身和右墩身之间，横撑杆包括第一杆节和第二杆节，环绕横撑杆设置若干钢管，钢绞线穿过钢管，第一杆节和第二杆节的连接处设置至少一块垫板，用于调节第一杆节和第二杆节之间的距离。本菱形索塔下塔柱线形调整结构，横撑杆和钢绞线形成内顶外拉的支撑结构，通过增减垫板的数量或厚度，可调节第一杆节和第二杆节之间的距离，从而使下塔柱线形向外或向内调整，方便后期进行调整，并且由于垫板的厚度可控制在精确范围内，因此能够提高下塔柱的线形精度，此发明用于桥梁建筑技术领域。 【EN】The invention discloses a linear adjusting structure and method for a lower tower column of a rhombic cable tower, which comprises the lower tower column, a transverse stay rod, a plurality of steel strands and the like, wherein the lower tower column comprises a left pier body and a right pier body, the transverse stay rod is arranged between the left pier body and the right pier body and comprises a first rod section and a second rod section, a plurality of steel pipes are arranged around the transverse stay rod, the steel strands penetrate through the steel pipes, and at least one base plate is arranged at the joint of the first rod section and the second rod section and used for adjusting the distance between the first rod section and the second rod section. According to the linear adjusting structure for the lower tower column of the rhombic cable tower, the transverse supporting rod and the steel strand form a supporting structure with an inner top and an outer pull, the distance between the first rod section and the second rod section can be adjusted by increasing or decreasing the number or the thickness of the base plates, so that the lower tower column is linearly adjusted outwards or inwards, later-stage adjustment is facilitated, and the linear accuracy of the lower tower column can be improved due to the fact that the thickness of the base plates can be controlled within an accurate range.

摘要：【中文】本发明公开了一种错位连接工艺凸台工装及加工工件的方法，包括工艺凸台本体和工作台，工艺凸台本体上设有压紧孔，螺栓穿过压紧孔将工艺凸台本体固定在工作台上，工艺凸台本体与工件之间通过连接件连接，连接件分别为高位连接块和低位连接块，所述高位连接块和低位连接块在横向与纵向上均错位排列，工件外形在高位和低位两个位置受压紧力作用，提高了装夹的稳定性，因此即使减少连接部位面积也可以保证工艺凸台连接强度和刚度。钳工易于下断和打磨，工作效率高。 【EN】The invention discloses a dislocation connection process boss tool and a method for processing a workpiece, wherein the tool comprises a process boss body and a workbench, a compression hole is arranged on the process boss body, a bolt penetrates through the compression hole to fix the process boss body on the workbench, the process boss body is connected with the workpiece through a connecting piece, the connecting piece is a high-position connecting block and a low-position connecting block respectively, the high-position connecting block and the low-position connecting block are arranged in a dislocation way in the transverse direction and the longitudinal direction, the shape of the workpiece is stressed by compression force at the high-position and the low-position, the clamping stability is improved, and the connection strength and the rigidity of the process boss can be ensured even if the area of a connection part is reduced.
