Hoop type combined cross beam
According to the technical scheme, the hoop type combined cross beam is characterized by comprising a pre-embedded steel plate arranged on a stand column and a vertical support fixed to the pre-embedded steel plate, hoops are arranged on the vertical support, each hoop is provided with a plurality of hydraulic jacks and a plurality of unloading blocks, cross beams are arranged on the unloading blocks, and the cross beams are erected in the transverse direction of a viaduct. The cross beam comprises a plurality of sections, the sections are connected through bolts, the cross beam is made of I45b I-shaped steel, and a plurality of transverse limiting devices are arranged on the cross beam. The multiple screw jacks are arranged on the outer side of the cross beam to jack up the steel truss, then the longitudinal moving rollers are installed on the cross beam and along the bottom of the steel truss, the cross beam serves as a track when the steel truss slides, and friction force generated when the steel truss slides can be effectively reduced. The cross beam is formed by splicing a plurality of sections, the upper connecting plate, the lower connecting plate and the middle connecting plate are arranged at the connecting part of every two adjacent sections and are connected through bolts, and therefore the length of the cross beam can be freely adjusted according to requirements.
本发明公开了一种抱箍式组合横梁，其技术方案的要点是包括有设在立柱上的预埋钢板、固定在预埋钢板上的竖撑，在竖撑上设有抱箍，在每个抱箍上设有多个液压千斤顶和多个卸落块，在卸落块上设有横梁，横梁沿高架桥的横向架设。横梁包括多段，每段之间通过螺栓连接，横梁采用I45b工字钢，在横梁上设有多个横向限位装置。本发明在横梁外侧设有多个螺旋千斤顶顶起钢桁架，然后在横梁上且沿钢桁架的底部安装纵移滚筒，横梁充当钢桁架滑移时的轨道，可有效减少钢桁架滑移时的摩擦力。横梁由多段拼接而成，相邻两段的连接部分设有上连接板、下连接板、中间连接板并通过螺栓连接，故横梁长度可根据需求任意调节。
