Description
Technical field
The utility model relates to a kind of concrete filled steel tube jack-up system that is applied in the building operations.
Background technology
The concrete lift-up construction technology is applied to the construction of the concrete filled steel tubular member in the heavy construction.Concrete filled steel tubular member is to fill self-compacting concrete and the member that forms in steel pipe, and steel pipe and core concrete thereof bear external load (power) effect jointly.As everyone knows, concrete compressive strength is high, but bending resistance is very limited, and the bending resistance of steel, particularly shaped steel is strong, has good elastoplasticity, but when pressurized easy unstability and lose the axial compression resistance ability.Concrete filled steel tubular member with the two advantages together, make concrete be in the three dimension stress state, its compressive strength can significantly improve, simultaneously because concrete existence, improved the rigidity of steel pipe, both play a role jointly, thereby have improved widely the supporting capacity of member.
Traditional concrete lift-up construction technology is that bottom (height so that the construction be advisable) tube wall at steel pipe column is opened a hole similar to the carrier pipe size, be attached thereto with the outlet of carrier pipe (pump line or high pressure pump line) with concrete pump, utilize pump pressure that concrete is injected in the steel pipe column continuously by carrier pipe, until fill with concrete in the pipe.Shown in Fig. 1 (concrete by the concrete pump jacking of ground floor to one of three steel pipe columns of certain floor), the carrier pipe supervisor (horizontal pump line) that the job site floor sets up, by vertically arranged carrier pipe standpipe carrier pipe supervisor one is terminated to a concrete pump, carrier pipe supervisor's the other end connects the first steel pipe column (shown in label among Fig. 1 5) with the carrier pipe arm.Carrier pipe supervisor and carrier pipe arm are formed general every joint 2～3m by the single-unit pipe of certain-length.General employing flange is connected between carrier pipe supervisor's joint and the joint, between carrier pipe supervisor and carrier pipe arm, carrier pipe arm and the carrier pipe arm generally the employing buckle be connected, be connected with a valve (flap valve) between carrier pipe arm and the steel pipe column, begin to carry out the concrete lift-up construction after complete when pipeline connects, valve-off flows out in the steel pipe column main body to prevent concrete after concrete lift-up is complete.
In traditional concrete lift-up construction, after a steel column lifting operation is finished, will implement following steps: 1, concrete pump is shut down; 2, close flap valve; 3, dismounting carrier pipe arm, and remove the interior residual concrete of pipe; 4, disengaging section carrier pipe supervisor, to regulate carrier pipe supervisor length to next lifting operation position, removing is disassembled the inner concrete of carrier pipe supervisor; 5, connecting conveying pipe supervisor, carrier pipe arm and next root steel pipe column; 6, the start of high pressure pump line and the operation of enforcement concrete lift-up.Under the regular situation, need 6-8 name labour to finish above-mentioned steps work in the time at 20～30min, if above-mentioned steps can not be finished in 20～30min, then the part concrete among carrier pipe standpipe and the carrier pipe supervisor may solidify, and the coarse aggregate (such as stone) in the concrete in the carrier pipe standpipe may precipitate downwards because of the gravity reason, thereby cause pump line to block, cause the concrete lift-up failure.
By above-mentioned situation as can be known, the defective of traditional concrete lift-up construction is as follows: 1, the engineering time is long, and owing to tearing pipe and connecting line length consuming time again open, so easily cause discontinuous construction, in other words, exactly owing to tear the pipe limited time open, so if misoperation (operating time is long), easily cause pump line to block, thereby bring about great losses.2, the concrete among carrier pipe arm and the part carrier pipe supervisor is because tearing pipe open, clearing up and can't re-use, so can cause waste, the concrete that goes out of use in addition can be laid on the work plane usually, so caused the problems such as environment pollution and refuse collection.
