Method for erecting bridge precast beam slab by using sand box type temporary support
The invention belongs to the technical field of bridge precast beam plate erection, and particularly discloses a method for erecting a bridge precast beam plate by using a sand box type temporary support, which comprises the following steps: manufacturing a cover plate with a conical structure, and forming a pouring hole in the cover plate; a circular outer steel drum with the diameter larger than that of the inner steel drum is manufactured, an opening of the outer steel drum faces upwards, a solid base is arranged at the bottom of the outer steel drum, and the top of the solid base is of a conical structure with the tip facing upwards; sand discharging openings which are obliquely and downwards formed along the conical face of the solid base are symmetrically formed in the two sides of the outer steel barrel, and screws are installed in nuts of the two sand discharging openings. Through cooperation of the cover plate of the conical structure, the conical groove is formed in the end of concrete poured into the inner steel barrel, and the solid base with the conical top face is arranged at the bottom of the outer steel barrel and can be clamped with the conical groove in a matched mode; and the conical surface of the solid base forms a flow guide inclined surface convenient for discharging the standard sand, and is matched with the sand unloading opening which is obliquely arranged, so that the standard sand can be conveniently guided out under the gravity action of the precast beam plate, and the sand discharging effect is good.
本发明属于桥梁预制梁板架设技术领域，具体公开了一种用砂箱式临时支座架设桥梁预制梁板的方法，包括制作锥形结构的盖板，并在盖板上开设浇注孔；制作直径大于内钢桶的圆形外钢桶，外钢桶开口朝上放置，其底部设置有实心基座，实心基座顶部为尖端向上的锥形结构；在外钢桶两侧对称设置有沿实心基座锥形面倾斜向下设置的卸砂口，在两卸砂口的螺帽内安装有螺杆。本发明在利用锥形结构的盖板的配合，使得灌注在内钢桶内的混凝土端部形成锥形凹槽，外钢桶底部设置具有锥形顶面的实心基座，能够与锥形凹槽配合卡接；实心基座的锥形面形成便于标准砂排出的导流斜面，与倾斜设置的卸砂口配合，便于在预制梁板的重力作用下将标准砂导出，排砂效果好。
