Abstract
The concreting method of a kind of concrete filled steel tube steel tower, comprises the following steps: a, with bolt by ring flange and tower body main material Flange joint；B, the sling point that rises using coaster to pass through on cantilever lift by crane concrete；C, concrete is poured in the main material of tower body by grouting mouth reserved on ring flange；D, complete the pouring of one section of main material of tower body after, remove the bolt of mounting flange and tower body main material flange, movable concrete lifting steelframe rises along with the group of iron tower main material is vertical, carries out pouring of next section of iron tower main material concrete；E, when pouring on next section of main material of tower body, repeat step a, b, c, d, until all main materials have poured.The present invention can realize the cast-in-place of concrete, but the requirement to construction machinery is relatively low, form of construction work is flexible, the area being difficult to arrive for concrete mixer can use the casting method of the present invention, the movable concrete lifting repeatable utilization of steelframe that the present invention uses, simple to operate, consumption of materials is few.
Description
Technical field
The present invention relates to the form of construction work of a kind of iron tower of power transmission line, be specifically related to a kind of for concrete filled steel tube steel tower
Concreting method.
Background technology
Along with the development of work transmission line, the size of steel tower, load there occurs the change of matter, and steel tower tends to maximizing,
As the component that bearing capacity is higher, concrete filled steel tube has begun to be applied to electric power line pole tower design.Steel tube concrete
Soil is remarkably improved the comprcssive strength of component compared with steel pipe, and it is long-pending to effectively reduce steel tube section, thus reduces bar cost, saves
Investment.The at present construction of concrete filled steel tube steel tower, mostly is after iron tower main material group founds certain altitude, by concrete mixer by outstanding
Concrete, to pipe top, is then poured in steel pipe by arm pump concrete.Owing to concrete mixer volume is relatively big, it is not suitable for landform
Big rise and fall and the poor area of transportation condition, have certain limitation.It is thus desirable to a kind of novel steel tube concrete steel tower of design
Concreting mode, to meet the concrete filled steel tube tower erection requirement of various orographic condition and transportation condition.
At present, adaptable to poor landform, the concreting method of easy construction has opens on iron tower main material
Hole, uses concrete mixer, by tapping, concrete pump is delivered to specific bit and puts, need again to iron tower main material after having poured
On perforate carry out repair welding.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of concreting speed fast, and the construction period is short, to various landform
The concreting method of the concrete filled steel tube steel tower that condition and transportation condition are all suitable for.
The purpose of the present invention is achieved through the following technical solutions:
The concreting method of a kind of concrete filled steel tube steel tower, comprises the following steps:
A. with bolt by ring flange and tower body main material Flange joint；
B. coaster is used to lift by crane concrete by the sling point that rises on cantilever；
C. concrete is poured in the main material of tower body by grouting mouth reserved on ring flange；
D., after completing the pouring of one section of main material of tower body, the bolt of mounting flange and tower body main material flange is removed, movable
Concrete lifting steelframe rises along with the group of iron tower main material is vertical, carries out pouring of next section of iron tower main material concrete；
When e. pouring on next section of main material of tower body, repeat step a, b, c, d, until all main materials have poured.
The lifting steelframe of movable concrete described in step d is made up of steel pipe, ring flange and cantilever.
At least 4 kinds of apertures and at least 10 screws are set on ring flange described in step a.
The present invention can realize the cast-in-place of concrete, and the requirement to construction machinery is relatively low, and form of construction work is flexible, for mixed
The area that solidifying soil pump truck is difficult to arrive can use the casting method of the present invention, the movable concrete lifting steelframe that the present invention uses
Repeatable utilization, simple to operate, consumption of materials is few.
Accompanying drawing explanation
Fig. 1 is the structural representation of movable concrete lifting steelframe in the present invention.
Fig. 2 is the section structure schematic diagram of ring flange in movable concrete lifting steelframe in the present invention.
In figure 1, play sling point, 2, cantilever, 3, steel pipe, 4, ring flange, 5, grouting mouth, 6, aperture be the screw of 1mm, 7, hole
Footpath is the screw of 2mm, 8, aperture be the screw of 3mm, 9, aperture be the screw of 4mm.
Detailed description of the invention
Embodiment 1
The concreting method of a kind of concrete filled steel tube steel tower, comprises the following steps:
A. with bolt by ring flange 4 and tower body main material Flange joint；
B. coaster is used to lift by crane concrete by the sling point 1 that rises on cantilever 2；
C. concrete is poured in the main material of tower body by grouting mouth 5 reserved on ring flange 4；
D., after completing the pouring of one section of main material of tower body, the bolt of mounting flange 4 and tower body main material flange is removed, movable
Concrete lifting steelframe rises along with the group of iron tower main material is vertical, carries out pouring of next section of iron tower main material concrete；
When e. pouring on next section of main material of tower body, repeat step a, b, c, d, until all main materials have poured.
The lifting steelframe of movable concrete described in step d is made up of steel pipe 3, ring flange 4 and cantilever 2.
At least 4 kinds of apertures and at least 10 screws are set on described ring flange 4.As it is shown in figure 1, on ring flange 4 from interior to
Outer be respectively provided with successively 12 apertures be the screw 6 of 1mm, aperture be the screw 7 of 2mm, aperture be that the screw 8 of 3mm, aperture are
The screw 9 of 4mm, to adapt to the main material Flange joint requirement of the tower body of different size, is carried out even by bolt and tower body main material flange
Connect.
In the present invention, movable concrete lifts by crane steelframe and the connected mode of iron tower main material and the shape of ring flange preformed hole
Formula can be adopted in other ways.
