Abstract
The utility model relates to a multilayer sandwich hollow steel tube foam concrete electric power tower, which comprises four main columns and bracing pieces among the main columns, wherein the main columns are cone-shaped hollow steel tube foam concrete columns; the bracing pieces are connected with the cone-shaped steel tube foam concrete columns by cone-shaped metal hoops on the external surfaces of the cone-shaped steel tube foam concrete columns; the cone-shaped steel tube foam concrete columns comprise two layers of steel tubes and reinforced foam concrete columns which are poured in the two layers of steel tubes; the raw material of the reinforced foam concrete columns is reinforced foam concrete which comprises waste brick slags, pulverized fuel ash, mountain flour, sand, gypsum, a compound additive, a liquid state foaming agent and steel fibers. The multilayer sandwich hollow steel tube foam concrete electric power tower has the advantages of light weight, strong bearing capacity, low cost and good quality.
Description
Technical field
The utility model relates to a kind of multilayer sandwich hollow steel pipe foam concrete electric tower, belongs 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.
Utility model content
For existing deficiency, the utility model provides a kind of multilayer sandwich hollow steel pipe foam concrete electric tower.
The technical solution of the utility model 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.

Described taper hollow steel pipe foam concrete post 1, as shown in Figure 3, comprise two-layer steel pipe 4 and be cast in the enhancement mode foam concrete post 5 in two-layer steel pipe 4, the top of described enhancement mode foam concrete post 5 is provided with plate platform 6, plate platform 6 and the 4 top cross-section combinations of two-layer steel pipe.
Described enhancement mode foam concrete post 5 sources are 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.
By cone-shaped metal anchor ear 3, taper hollow steel pipe foam concrete post 1 and support bar 2 are coupled together, build and form multilayer sandwich hollow steel pipe foam concrete electric tower of the present utility model.
