Abstract
The invention discloses a multilayer sandwiched hollow steel tube foam concrete column tower which comprises a main column and a cross arm. The cross arm is erected on the main column. The main column comprises two sleeves and reinforced type foam concrete columns poured in the two sleeves, a steel plate platform is arranged at the tops of the reinforced type foam concrete columns, and the steel plate platform is combined with the cross sections of the tops of two layers of steel tubes. Each reinforced type foam concrete column is made of reinforced foam concrete which comprises waste brick slag, coal ash, mountain flour, sand, gypsum, a composite additive, foaming agent liquid and steel fibers. According to the multilayer sandwiched hollow steel tube foam concrete column tower, the bearing capacity of the steel tubes can be increased, weight is light due to the hollow structure, and the multilayer sandwiched hollow steel tube foam concrete column tower can be used as the main column and can also be used as the cross arm.
Description
Technical field
The present invention relates to a kind of steel pipe foam concrete shaft 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 shaft tower.
Technical scheme of the present invention is as follows:
Multilayer sandwich hollow steel pipe foam concrete shaft tower, it comprises mobile jib and cross-arm, cross-arm is erected on mobile jib, described mobile jib comprises two-layer steel pipe and is cast in the enhancement mode foam concrete post in two-layer steel pipe, 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 enhanced type steel envelope foam concrete post source is enhanced type steel envelope foam concrete, and enhanced type steel envelope foam concrete comprises deposed brick slag powder, flyash, stone flour, sand, gypsum, compound additive, aqueous foaming agent and steel fibre.
The additional stirrup of described steel pipe, is fixedly connected with the mobile jib of more piece.
The match ratio of described enhanced type steel envelope 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 shaft 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, be applicable to house, industrial construction, the isostructural main support of architectural style and support component.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of multilayer sandwich hollow steel pipe foam concrete shaft tower of the present invention.
The specific embodiment
As shown in Figure 1, multilayer sandwich hollow steel pipe foam concrete shaft tower, it comprises mobile jib and cross-arm, cross-arm is erected on mobile jib, described mobile jib comprises two-layer steel pipe 1 and is cast in the enhancement mode foam concrete post 2 in two-layer steel pipe, the top of described enhancement mode foam concrete post 2 is provided with plate platform 4, plate platform 4 and the 1 top cross-section combination of two-layer steel pipe.
Described enhanced type steel envelope foam concrete post 2 sources are enhanced type steel envelope foam concretes, and enhanced type steel envelope foam concrete comprises deposed brick slag powder, flyash, stone flour, sand, gypsum, compound additive, aqueous foaming agent and steel fibre.
The additional stirrup 3 of described steel pipe.
The match ratio of described enhanced type steel envelope 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.
By stirrup 3, the multilayer sandwich hollow steel pipe foam concrete mobile jib of more piece is coupled together, form quality light, the mobile jib of the practicality shaft tower that bearing capacity is high, with low cost.
