Abstract
Enhanced steel tube foam concrete electric tower includes four supporting rods between principal post and principal post, and principal post is the enhanced steel tube foam concrete column of taper, and supporting rod with the cone-shaped metal anchor ear of conical steel pipe foam concrete outer surface of column by connecting.Conical steel pipe foam concrete column is enhanced steel tube foam concrete column, the raw material of enhanced foam concrete column is enhanced foam concrete, and enhanced foam concrete includes deposed brick slag, flyash, mountain flour, sand, gypsum, compound additive, liquid foaming agent and steel fibre.The pylon of the present invention fills the enhanced foam concrete poured, increases the bearing capacity of steel pipe, alleviates the quality of pylon, and reduces the cost of pylon.
Description
Technical field
The present invention relates to a kind of enhanced steel tube foam concrete electric towers, belong to building engineering field.
Background technology
It refers to the filled and process concrete in steel pipe that steel tube foam concrete, which combines column, and coagulation is arranged in outer wall of steel pipe
The composite pillar of protective soil layer.
Steel core concrete column started to introduce China in middle 1960s, and steel pipe is mixed in less than 50 years
Solidifying soil technology whether has rapid development, the steel pipe used in existing industrial, civil buildings mixed from theoretical or technology
Solidifying soil pillar is mostly simply to pour into a mould portland cement concrete in steel pipe to be made.Early stage steel core concrete column passes through steel
The characteristics of pipe greatly compensates for concrete high brittleness to the effect of the lateral confinement of concrete；The concrete filled in steel pipe simultaneously
Steel pipe is limited to be deformed.Since its comprehensive performance is much better than simple reinforced column, so having obtained a large amount of
It uses.As building develops to high stratification, complication direction, some shortcomings of conventional steel concrete column is gradually shown
Come.First, the strength and stiffness of steel core concrete column greatly increase, but its shock resistance is not improved well, on ground
Brittle break easily occurs for the concrete under the repeated action of brisance in steel pipe, causes the reduction of column bearing capacity.Secondly, in high tender feeling
Steel pipe can deform under condition, these harm can all influence the stress of concrete column.
Chinese patent application 201310047960.9 proposes a kind of steel tube foam concrete combination column and its construction party
Method, but its structure is complex, and quality is bigger than normal, and cost is opposite or higher.
Invention content
For existing deficiency, the present invention provides a kind of enhanced steel tube foam concrete electric tower.
Technical scheme is as follows：
Enhanced steel tube foam concrete electric tower, it includes four supporting rods between principal post and principal post, and principal post is
The enhanced steel tube foam concrete column of taper, supporting rod pass through the taper with the enhanced steel tube foam concrete outer surface of column of taper
Metal anchor ear connects.
The enhanced foam concrete column of the taper includes steel pipe and is cast in the enhanced foam coagulation of steel duct
Earth pillar, enhanced foam concrete column top set plate platform, and plate platform and steel pipe upper surface combine.
The taper enhanced foam concrete column source is enhanced foam concrete, enhanced foam concrete packet
Include deposed brick slag powder, flyash, mountain flour, sand, gypsum, compound additive, liquid foaming agent and steel fibre.
The match ratio of the enhanced foam concrete is deposed brick slag powder 35% ~ 40%, flyash 15% ~ 25%, mountain flour 12%
~ 15%, sand 22% ~ 25%, gypsum 3% ~ 5%, compound additive 2% ~ 3%, liquid foaming agent 0.15%, steel fibre 0.05%, ratio of water to material
0.21。
The compound additive is 1 by mass ratio:1.1 C-3 water-reducing agents and swelling agent composition.
The enhanced steel tube foam concrete electric tower of the present invention increased steel fibre, Ke Yiyou in foam concrete
Effect ground improves the load resistant power of foam concrete and steel pipe, and raw material is brick ground-slag, flyash, mountain flour, sand, gypsum etc., is come
Source is extensive, simple in structure, of low cost, and light weight, and intensity is high.

The enhanced foam concrete column 1 of the taper, as shown in figure 3, including steel pipe 4 and the increasing for being cast in steel duct
Strong type foam concrete column 5, enhanced 5 top of foam concrete column set plate platform 6, plate platform 6 and 4 upper surface of steel pipe knot
It closes.
Enhanced 1 source of foam concrete column of the taper is enhanced foam concrete, enhanced foam concrete
Including deposed brick slag powder, flyash, mountain flour, sand, gypsum, compound additive, liquid foaming agent and steel fibre.
The match ratio of the enhanced foam concrete is deposed brick slag powder 35% ~ 40%, flyash 15% ~ 25%, mountain flour 12%
~ 15%, sand 22% ~ 25%, gypsum 3% ~ 5%, compound additive 2% ~ 3%, liquid foaming agent 0.15%, steel fibre 0.05%, ratio of water to material
0.21。
The compound additive is 1 by mass ratio:1.1 C-3 water-reducing agents and swelling agent composition.
The enhanced foam concrete column 1 of taper is connected with supporting rod 2 by cone-shaped metal anchor ear 3, takes construction cost
The enhanced steel tube foam concrete electric tower of invention.
