Prestressed strut reinforced concrete beam structure
The invention discloses a prestressed strut reinforced concrete beam structure. The structure is characterized in that a steel beam is arranged below a concrete beam, the left side and the right sideof the midspan position of the concrete beam are correspondingly provided with middle supporting point prestressed struts, and a horizontal strut is arranged between the left middle supporting point prestressed strut and the right middle supporting point prestressed strut. Steel anchoring hoops connected with the lower end parts of the middle supporting point prestressed struts are arranged at theposition of 600-700 mm below a concrete floor slab, side supporting point prestressed struts are arranged at the positions of 1/4 and 3/4 of the concrete beam in a span direction, steel anchoring hoops connected with the lower end parts of the side supporting point prestressed struts are arranged at the position of 450-550 mm below the concrete floor slab, tension bolts are arranged in the middles of the prestressed struts, the tensioning bolts are fixedly connected with the lower prestressed struts, and the tension bolts are in screwed connection with the upper prestressed struts.
本发明公开了一种预应力撑杆加固混凝土梁结构，其特征是在混凝土梁下面设置钢梁，混凝土梁跨中位置左侧和右侧分别设置中支点预应力撑杆，左侧中支点预应力撑杆和右侧中支点预应力撑杆之间设置水平撑杆。与中支点预应力撑杆下端部联接的钢锚固箍设置在混凝土楼板下方600～700mm位置，混凝土梁沿跨度方向1/4位置和3/4位置均设置边支点预应力撑杆，与边支点预应力撑杆下端部联接的钢锚固箍设置在混凝土楼板下方450～550mm位置，预应力撑杆中部均设置张拉螺栓，张拉螺栓与下部预应力撑杆为固接，张拉螺栓与上部预应力撑杆为丝扣连接。
