Abstract
The invention provides a multilayer hollow sandwich steel tube and foam concrete electric tower. The electric tower comprises four main columns and support rods between the main columns. Each main column is a hollow tapered steel tube and foam concrete column. The support rods are connected with the hollow tapered steel tube and foam concrete columns through tapered metal hoops on the outer surfaces of the tapered steel tube and foam concrete columns. Each tapered steel tube and foam concrete column includes two layers of steel tubes and a reinforcing foam concrete column which is formed between the two layers of steel tubes in a pouring mode. The reinforcing foam concrete column is made of reinforcing foam concrete. The reinforcing foam concrete includes waste brick slag, fly ash, stone powder, sand, plaster, compound admixtures, liquid foaming agents and steel fiber. The multilayer hollow sandwich steel tube and foam concrete electric tower has the advantages of light weight, high bearing capacity, low cost and good quality.
Description
Technical field
The present invention relates to a kind of multilayer sandwich hollow steel pipe foam concrete electric tower, belong to building engineering field.
Background technology
Steel pipe foam concrete combination column refers to filled and process concrete in steel pipe, and the composite pillar of concrete cover is set at outer wall of steel pipe.
Steel core concrete column starts to introduce China in middle 1960s, no matter concrete filled steel tube technology is from theory or technology has had development rapidly in less than 50 years, the concrete filled steel tube pillar using in existing industry, civilian construction is mostly to be poured into a mould simply portland cement concrete and is made in steel pipe.Early stage steel core concrete column has made up the feature of the high fragility of concrete greatly to concrete horizontal restrain effect by steel pipe; The concrete of simultaneously filling in steel pipe has limited steel pipe and has produced distortion.Because its combination property is better than simple reinforced concrete post far away, so obtained a large amount of uses.Along with building is to high stratification, complicated future development, the some shortcomings part of conventional steel concrete column shows gradually.First, the strength and stiffness of steel core concrete column increase greatly, but its shock resistance well do not improved, and brittle fracture easily occurs the concrete under the repeated action of seismic forces in steel pipe, cause column bearing capacity to reduce.Secondly, under high-temperature condition, steel pipe can deform, and these harm all can affect the stressed of concrete column.
Chinese patent application 201310047960.9 has proposed a kind of steel pipe foam concrete combination column and construction method thereof, but its complex structure, quality is bigger than normal, and cost is relatively still higher.
Summary of the invention
For existing deficiency, the invention provides a kind of multilayer sandwich hollow steel pipe foam concrete electric tower.
Technical scheme of the present invention is as follows:
Multilayer sandwich hollow steel pipe foam concrete electric tower, it comprises the support bar between four principal posts and principal post; Described principal post is taper hollow steel pipe foam concrete post, and support bar is by being connected with the cone-shaped metal anchor ear of taper hollow steel pipe foam concrete outer surface of column.
Described taper hollow steel pipe foam concrete post comprises two-layer steel pipe and be cast in the enhancement mode foam concrete post in two-layer steel pipe, and the top of described enhancement mode foam concrete post is provided with plate platform, plate platform and the cross section combination of two-layer steel pipe top.
Described enhancement mode foam concrete post source is enhancement mode foam concrete, and enhancement mode foam concrete comprises deposed brick slag powder, flyash, stone flour, sand, gypsum, compound additive, aqueous foaming agent and steel fibre.
The match ratio of described enhancement mode foam concrete is deposed brick slag powder 35% ~ 40%, flyash 15% ~ 25%, stone flour 12% ~ 15%, sand 22% ~ 25%, gypsum 3% ~ 5%, compound additive 2% ~ 3%, aqueous foaming agent 0.15%, steel fibre 0.05%, ratio of water to material 0.21.
C-3 water reducing agent and expansion agent that described compound additive is 1:1.1 by mass ratio form.
The steel fibre that multilayer sandwich hollow steel pipe foam concrete electric tower of the present invention increases in foam concrete, can effectively improve the load resistant power of foam concrete and steel pipe, and raw material is brick ground-slag, flyash, stone flour, sand, gypsum etc., wide material sources, simple in structure, with low cost, and quality is light, and intensity is high.
