Cast-in-place box girder support and construction method thereof
The invention discloses a cast-in-place box girder support and a construction method thereof.The cast-in-place box girder support comprises a box girder top and a trapezoid box girder bottom integrally formed with the box girder top, a bamboo plywood is arranged on the upper top face of the interior of the trapezoid box girder bottom, and square timber is installed between the bamboo plywood and the top face of the interior of the trapezoid box girder bottom; at least three supporting rods which are arranged side by side in the left-right direction are installed in the trapezoid box girder bottom, each supporting rod comprises a supporting rod body and a threaded rod which is inserted into the supporting rod body from top to bottom, nuts are rotatably installed at the upper ends of the supporting rod bodies, and the nuts and the threaded rods are rotatably connected through threads. The supporting rods are arranged, the threaded rods are arranged above the supporting rods, the bearing strength of the top of the box girder can be improved through the supporting rods, when the top of the upper box girder sinks, the nut can be rotated to enable the threaded rods to ascend, the sunken top of the box girder is jacked up, and it is guaranteed that the top of the box girder is horizontal; the bamboo plywood is high in hardness and resistant to fracture and compression, and the strength of the structure is enhanced.
本发明公开了一种现浇箱梁支架及其施工方法，包括箱梁顶以及与箱梁顶一体成型的梯形箱梁底，所述梯形箱梁底的内部上顶面设有竹胶板，所述竹胶板与梯形箱梁底的内部顶面之间安装有方木，所述梯形箱梁底的内部安装有至少三个左右并排的支撑杆，所述支撑杆包括支撑杆以及从上向下插入支撑杆内部的螺纹杆，所述支撑杆的上端转动安装有螺母，所述螺母与螺纹杆之间通过螺纹转动连接。本发明设置了支撑杆以及在支撑杆上方设置螺纹杆，支撑杆的设置可将箱梁顶的承重强度加大，并且在上方箱梁顶有下陷时，可通过旋转螺母，使得螺纹杆上升，来将下陷的箱梁顶顶起，保证箱梁顶的水平，采用竹胶板代替钢板，竹胶板硬度高、抗折、抗压，增强本结构的强度。
