The lattice type steel rib concrete-filled steel tube composite component mainly comprises a hollow ring-shaped steel tube and concrete which is injected into the ring-shaped steel tube, wherein longitudinal pass-length stiffening plates are evenly distributed on the inner wall of the ring-shaped steel tube in a spaced mode, the longitudinal stiffening plates can improve flexural rigidity and can be used for connection between the steel tube and steel ribs, transverse stiffening plates are distributed in the ring-shaped steel tube in the vertical direction at equal intervals, the transverse stiffening plates are used for improving performance of together working between the concrete and the steel tube, the lattice type steel ribs are arranged inside the ring-shaped steel tube, the lattice type steel ribs are connected with the longitudinal stiffening plates through bolts, round steel rotating shafts which facilitate concrete filling construction are distributed in the lattice type steel ribs at equal interval, and a safety protective ring and station platforms are arranged on the inner wall of the upper portion of the ring-shaped steel tube, and provide space to facilitate construction. The lattice type steel rib concrete-filled steel tube composite component has the advantages of being simple and reasonable in structure, convenience to use, reliable in use, capable of improving processing efficiency and construction efficiency, and the like.
Description
Technical field
The utility model relates to a kind of component form of overhead transmission line steel pipe iron tower, in particular, relate to a kind of composite component form of steel tube tower body of the tower master material.
Background technology
In towering and large-span structure, pillar need bear very high axle power, is the bearing strength and the ductility that satisfy post, and the steel-concrete combined member is widely adopted in engineering.Common steel-concrete post mainly contains combined steel and concrete column and steel core concrete column.
Combined steel and concrete column, reinforcing bar are wrapped in the concrete, have improved supporting capacity and the ductility of pillar, and concrete has increased the rigidity of reinforcing bar, anti-cripling and complete buckling ability simultaneously, and the reinforcing bar in the combined steel and concrete column adopts real abdomen formula member more at present.
Steel core concrete column is that concrete is injected the composite component that forms in the steel pipe of sealing.In the combining structure, not only the compressive strength of three dimension stress core concrete is significantly improved, and in pressurized process, the cripling of thin ancient piece of jade, round, flat and with a hole in its centre steel pipe and complete buckling are inhibited and delay, and the load-carrying properties of a steel pipe ancient piece of jade, round, flat and with a hole in its centre are also greatly strengthened.But along with the increase of external load, as improving diameter of steel tube simply, will cause the cross section steel ratio to reduce, member ductility can't meet design requirement.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and has than the bigger supporting capacity of conventional components form, better ductility, can satisfy the lattice reinforcing bar concrete filled steel tube composite component applicable to big load multiloop power transmission tower of Structural Design Requirement.
The utility model is achieved by the following technical solution: it mainly comprises hollow ring steel pipe and the interior concrete that injects of ring steel pipe, described ring steel pipe inwall evenly at interval is furnished with vertically elongated stiffener, and it can be used for being connected of steel pipe and reinforcing bar when improving bending rigidity; Along being furnished with horizontal stiffener every certain altitude between the upper and lower, in order to strengthen the co-operation performance of concrete and steel pipe, the ring steel duct is provided with the lattice reinforcing bar in the ring steel pipe, and this lattice reinforcing bar links to each other with bolt with vertical stiffener by junction plate.
Keep at a certain distance away in the described lattice reinforcing bar and be furnished with round steel rotating shaft be used to making things convenient for concrete perfusion construction; Be furnished with safeguard protection circle and erect-position platform on the upper inside wall of described ring steel pipe, so that the space convenient construction to be provided.
Continuous upgrading along with the transmission line construction scale, the application of steel tube tower is extensive all the more in big leap and the UHV transmission line, for improving power transmission tower principal post supporting capacity, guarantee member ductility simultaneously, the utility model is in achievement in research and the pluses and minuses of summing up combined steel and concrete column and steel core concrete column, with both in conjunction with so that a kind of novel combining structure proposed, reinforcing bar is imbedded steel core concrete column, the name steel frame-steel pipe concrete column, for obtaining better cross section anti-bending strength, and improve and process, efficiency of construction does not adopt conventional real abdomen formula reinforcing bar, but selects lattice reinforcing bar form for use; Thereby make to the utlity model has simple and reasonable for structurely, easy to use, reliable, can improve processing and characteristics such as efficiency of construction.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Fig. 1,2,3,4,5, the utility model mainly comprises hollow ring steel pipe 1 and the interior concrete 2 that injects of ring steel pipe, described ring steel pipe 1 inwall evenly is furnished with vertically elongated stiffener 4 at interval, the edge is furnished with horizontal stiffener 5 every certain altitude between the upper and lower in the ring steel pipe 1, ring steel pipe 1 inside is provided with lattice reinforcing bar 3, and this lattice reinforcing bar 3 links to each other with bolt by junction plate 6 and vertical stiffener 4.
Keep at a certain distance away in the described lattice reinforcing bar 3 and be furnished with round steel rotating shaft 9 be used to making things convenient for concrete perfusion 2 construction; Be furnished with safeguard protection circle 7 and erect-position platform 8 on the upper inside wall of described ring steel pipe 1.
Steel tube component adds man-hour, and inwall has welded vertical, horizontal ribbed in advance, in position installs safeguard protection circle and erect-position platform simultaneously.During the member on-site consolidation, overall package lattice reinforcing bar at first, and with above-mentioned steel tube component hoisted in position, by junction plate both are linked to each other by bolt then, last concrete perfusion forms integral body.
It should be noted that above what enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and a lot of distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
