Fish-bellied sill device capable of increasing prestress
The invention discloses a fish belly sill device capable of increasing prestress. Belongs to the field of foundation pit engineering support. Comprising triangular keys, steel strands, enclosing purlins, rectangular steel supporting beams, diagonal bracings, arc-shaped steel beams, straight web members, end connecting components, concrete base plates, anchoring devices, fastening devices, diagonal web members, rotating shaft devices, cross beams, connecting devices, clamping grooves, semicircular connecting pieces, rectangular base plates, stiffening plates, locking steel strand anchorage devices, prestress locking devices, angle rotating discs and tension components. And a rotating rod and a steel pipe are arranged. The angle change in the large-span prestress fish-belly sill foundation pit supporting construction process can be adjusted, and the foundation pit supporting stress is effectively controlled by connecting the enclosing purlins and the web members at the ends of the diagonal web members through the connecting devices, the clamping grooves and the semicircular connectors. A component for preventing the fish-bellied sill from lowering the head is additionally arranged and is arranged at a certain position on the outer side of the fish-bellied sill; safety and reliability can be guaranteed, the supporting structure can be flexibly arranged, stress is clear, and deformation of the foundation pit can be effectively controlled.
本发明公开了一种增大预应力的鱼腹梁装置。属于基坑工程支护领域，包括三角键、钢绞线、围檩、矩形钢撑梁、剪刀撑、弧形钢梁、直腹杆、端部连接构件、混凝土垫板、锚固装置、紧固装置、斜腹杆、转轴装置、横梁、连接装置、卡槽、半圆形连接件、矩形垫板、加劲板、锁定钢绞线锚具、预应力锁定装置、角度转盘、拉力构件、转杆及钢管等设备。本发明可以调节大跨度预应力鱼腹梁基坑支护施工过程角度变化，在斜腹杆端部通过连接装置、卡槽、半圆形连接和将围檩和腹杆连接，有效控制基坑支撑受力。本发明还增加了防止鱼腹梁低头的构件，置于鱼腹梁外侧一定位置处；既能保证安全及可靠性，亦可使支护结构布置灵活，受力明确，可有效控制基坑的变形。
