InactiveCN101824917APrevent backflowPrevent spillageStrutsBuilding material handlingSteel tubeGlobe valve
The invention relates to a column core concrete lift-up connecting device of a steel pipe column, belonging to the technical field of building construction. The device comprises an elbow with a horizontal port and an upwarping port. A one-way valve cover is installed at the higher side of the upwarping port of the elbow through a hinge, and the higher side of the upwarping port extends into the steel pipe column from the lower part of the steel pipe column; the horizontal port of the elbow is connected with a pumping line, and the pumping line is provided with a stop valve with a plug-in board. When the device works, the upwarping end extends into the steel pipe column, but not clings to the pipe wall of the steel pipe column, therefore, concrete is pumped out by a pipe core with favorable pouring effect; a one-way valve and the stop valve prevent the concrete from flowing backwards respectively at the inside and the outside of the steel pipe column, and therefore, the invention fulfills a function of double insurance, is reliable, also has favorable sealing effect and can keep the lift-up pressure; and when the pressure in a pipe is larger, the one-way valve firstly shares the pressure, thereby efficiency avoiding overflowing of the concrete at the stop valve, therefore, the invention is particularly suitable for pouring the higher steel pipe column.
