Whether disconnected concrete is closely knit.Pouring for same root steel pipe column 1 should be carried out continuously, and the midfeather time is first no more than concrete
The solidifying time；When concrete cannot be in time for that at once, should take intermittent pumping mode.
Embodiment
It as shown in Figure 1: include the pouring hole 3 that 1 side wall of steel pipe column is opened, pouring hole 3 is poured as the concrete of lower layer's steel pipe column
That builds pump line puts in hole.Pouring hole 3 is located at the 2 above 800mm~1200mm of top surface absolute altitude of floor girder steel, the height position of pouring hole 3
Casting concrete should be convenient for by setting.One drain hole 4 is set down apart from 3 center line of pouring hole, drain hole 4 is for draining and controlling
The absolute altitude of concreting.When Specific construction, at the pouring hole 3 in inner wall of steel pipe column 9 paste a reinforcement with a thickness of 25mm
Ring 6, for reinforcing ring 6 as shown in Fig. 2, reinforcing ring 6 is equipped with grout hole 8, the axis of grout hole 8 is consistent with the axis of pouring hole 3.It pours
Build hole 3 and drain hole 4 be all made of cutting technique and cut, the pouring hole raw steel plate 10(cut down is shown in Fig. 3) it is used for
Pouring hole 3 is blocked after the completion of concreting；The drain hole raw steel plate 5(cut down is shown in Fig. 4) it is poured for concrete
Drain hole 4 is blocked after the completion of building.When closure, copes with pouring hole 3 and pouring hole raw steel plate 10 and drain hole 4 and sluice
Hole raw steel plate 5 is polished, and pouring hole raw steel plate 10 and 5 surrounding of drain hole raw steel plate is polished groove, then in groove
Surrounding weld all around is completed, weld seam answers full bubble-free.Weld seam grade is first-order weld.6 outer arc of reinforcing ring should be with 9 arc of inner wall of steel pipe column
It spends identical, it is ensured that 6 outer arc of reinforcing ring is fitted closely with steel pipe column inner arc.Fitting uses the weld all around of angle fillet surrounding.
The present invention constructs according to the following steps:
1, the cutting of pouring hole 3 and drain hole 4 on steel pipe column 1 is completed according to drawing in professional chemical plant；What is cut down pours
Hole raw steel plate 10 and drain hole raw steel plate 5 retain spare.And the production of reinforcing ring 6 is completed according to drawing in professional chemical plant, and
Reinforcing ring 6 is welded in the inner wall of steel pipe column 9 of 3 corresponding position of pouring hole；
2, steel pipe column 1 is end to end, complete the installation of steel pipe column 1；It is completed at the same time the connection of steel pipe column 1 Yu floor girder steel；
3, operating platform 11 is set up outside the pouring hole 3 of steel pipe column 1；And it is set up at 11 edge of operating platform and faces side guardrail 12；
4, vertical pump line 17 is laid using operating platform 11, vertical pump line 17 is connected using connecting flange 15, and vertical pump line 17 is logical
Bracket 14 is crossed to connect with floor girder steel 2；
5, one section of vertical pump line 17 being located at outside pouring hole 3 is removed, and in next section of 17 top of vertical pump line connection quarter bend pump
Pipe 16,16 other end of quarter bend pump line are protruded into steel pipe column 1 and are connect through connecting flange 15 with eyesight elbow 13；Eyesight elbow 13 goes out
Mouth end is bent downwardly and is overlapped with the center line of steel pipe column 1；
6, in 16 bottom of quarter bend pump line setting support 7, support 7 and operating platform 11 or face side guardrail 12 and connect.
7, concreting is carried out；Concreting is vibrated using layering, and layer height is not more than 1 meter, when layering rests
Between, it is put in steel pipe column 1 and is vibrated from pouring hole 3 using intermediate frequency vibrating spear.The artificial mallet of 1 fit on of steel pipe column strikes simultaneously
It hits, judges whether concrete is closely knit according to sound.The pumping dynamics that pump truck should be controlled when pouring enables concrete hang down in cavity
It is straight to fall, the self-compaction of concrete is reached using the kinetic energy that concrete whereabouts generates.And controlled using drain hole 4, it pours
Build to drain hole 4 overflow concrete grout when, that is, stop pour.Concreting forming surface in lower section steel pipe column 1 is away from drain hole 4
Distance cannot be less than 500mm.
8, after the completion of a layer concrete pours, pouring hole raw steel plate 10 is carried out before concreting after carrying out upper layer and is let out
Water hole raw steel plate 5 blocks welding, and weld seam grade is first-order weld.It must be strictly controlled welding sequence when welding, after the completion of welding
It needs to carry out carrying out flaw detection qualification, guarantees quality.
When carrying out pouring hole raw steel plate 10 and drain hole raw steel plate 5 and blocking welding, it should be ensured that 1 concrete is not in steel pipe column
It can be impaired because welding.Same root steel pipe column 1 should be carried out continuously when pouring, initial set of the midfeather time no more than concrete
Time.When concrete cannot be in time for that at once, should take intermittent pumping mode.
Concreting process carries out from the bottom to top, repeats step 5~8 until completing pouring for whole steel pipe column 1.
The present invention improves construction safety coefficient, shortens the construction period, plays to saving labour and construction cost
Good effect.The present invention has the characteristics that structure is simple, construction safety is convenient, time saving and energy saving.
