Abstract
The invention relates to a steel pipe concrete pouring construction device, in particular to a self-compacting concrete jacking-nonreturn device comprising a poured steel pipe column. The jacking-nonreturn device mainly a consists of a connecting pipe and a nonreturn valve. The steel pipe column is provided with an insertion slot; one end of the connecting pipe is inserted in the insertion hole of the steel pipe column, while the other end of the connecting pipe is connected with the nonreturn valve through a first pipe clamp; the other end of the nonreturn valve is connected with a high pressure hose through a second pipe clamp; the other end of the high pressure hose is connected with a pump pipe through a third pipe clamp; and the pump pipe is connected with a concrete pump. As the middle of the nonreturn valve of the device is connected by a flange and the flange is insert-connected with a steel plate wedge anchorage, the reflow of the concrete is prevented and the compactness of the concrete of the poured steel pipe column is ensured. The connection technology of the self-compacting concrete jacking-nonreturn device is simple in construction technology, fast in construction speed and low in labor intensity. The self-compacting concrete jacking-nonreturn device has no noise and no disturbance to people, reduces pollution, improves the environment and achieves good environmental benefit. The self-compacting concrete jacking-nonreturn device has a positive popularization role in environment-friendly construction and the application of new technique and new technology.
Description
Technical field
The present invention relates to a kind of concrete filled steel tube casting and constructing device, particularly relate to a kind of from secret room concrete lift-up check device.
Background technology
It all is to send out construction with high the throwing that present most concrete filled steel tube is built, and promptly builds from top to bottom with tower crane.The defective that the method exists:
1, highly higher owing to building, conventional job practices can not guarantee construction quality, occurs phenomenons such as segregation, separation in the concreting process easily, can not guarantee concrete compactness;
2, Chang Gui casting method does not meet the green construction requirement;
Three layers was a joint when 3, most steel pipe columns were installed, and needed with special-purpose vibrating head operation, and workman's difficulty of construction is bigger, and speed of application is slow, and need take the plenty of time of tower crane, has increased a large amount of labour costs and mechanical one-shift expense.Along with the application and the development of construction technology, the mode that conventional concrete filled steel tube adopts tower crane to build can not satisfy the green construction requirement.Under the advocating of green construction, how to solve building of concrete filled steel tube, energy-saving and environmental protection, new technology application have become the problem that needs to be resolved hurrily.
Summary of the invention
Goal of the invention of the present invention is the many deficiencies at prior art, provides a kind of simple in structure, easy to operate, can effectively prevent the self-compacting concrete jacking check device that coagulation refluxes when removing delivery pump pipe that is cast in of concrete filled steel tube.
Realize the foregoing invention purpose by the following technical solutions: a kind of self-compacting concrete jacking ends
Return device, comprise the steel pipe column of being poured into a mould, described check device mainly is made up of tube connector, flap valve, have jack on the described steel pipe column, tube connector one end inserts in the jack of steel pipe column, and the other end is connected with flap valve by first pipe clamp, and the other end of flap valve is connected with high-pressure hose by second pipe clamp, the other end of high-pressure hose is connected with pump line by the 3rd pipe clamp, and pump line is communicated with concrete pump.
Adopt technique scheme, compared with prior art, remarkable result of the present invention is: because the centre of the flap valve of device connects with flange, grafting steel plate wedge anchorage on the flange prevents that concrete from refluxing and the concrete compactness of steel pipe column of assurance cast.Link technique construction technology from secret room concrete lift-up check device is simple, and speed of application is fast, and labour intensity is low.Noiselessness, do not disturb residents, reduce and pollute, improve environment, have good environmental benefit.For green construction, the application of new technology, new technology has positive popularizing action.
